A gravity power generating unit having pressure load equipment is shown in Patent Documents 9 to 14. Pressure force by an oil pressure, an air pressure and weight, and a little pressure force by a water pressure, a vapor pressure and a water stream are injected in a large aperture of a cylinder of each pressure load equipment, A stroke of the cylinder is smallest not to cause a pressure drop. In the cylinder, a slight amount of capacity is injected and discharged. Pressure load balances are provided on central axes of a plurality of trunnion double rod cylinders on the right and the left of a fulcrum and are subject to the power (gravity) increased according to the ratio of upper and lower two stage balances. Top and bottom chambers of the cylinder are filled up with oil sealed up, and a closed circuit variable displacement hydraulic pump is actuated by an external power to switch the top and bottom chambers alternately. The increased power is input into a crank mechanism by reciprocating balances with an upper portion of a rod. Or, the water pressure, a steam pressure are added to a head chamber, a top and bottom rod chamber by using a double acting single rod or a double rod cylinder of a water pressure or steam pressure, instead of the double rod oil hydraulic cylinder. The water pressure and the steam pressure may be used together with oil pressure. The increased output force is gradually input from the input device which is installed on the ground of the front edge side of a load balance to a power generating output power by the existing rotation output by external power (a waterwheel, a heat turbine, a wind turbine, solar light, a water stream). The object of the power generator is to achieve increase in generation output while balancing with the load output. According to the present invention, the power which is increased by the pressure load equipment is input from the reciprocating power transfer unit to the power generator by coupling with a rotating axis of large or small horizontal axis or vertical axis wind turbine power generator, an axis of large or small gas or steam turbine power generator, a solar power generator, or a rotating axis of an engine of a large-scale ship (of a water stream) and a power generator propellant axis drive. Or a power is increased by the pressure load equipment using a regenerated surplus power of the primary, the secondary, the tertiary substations, a railway construction site, and a large-scale plant, and the increased power is input from the reciprocating power transfer unit to the power generator.
The quantity of water in dam is limited. Although in steam or gas turbine power generating, waste heat from thermal engine is reused, cost for uranium, natural gas, coal, crude oil is limited. The natural energy such as wind power, solar power generator is ranked as renewal energy but inefficient, and is employed as complex power generation which is incorporated in existing commercial power generation. Nuclear energy provokes anxiety for the future in terms of discharge of carbon dioxide. Each power generating system has disadvantage. In the present invention, as an assist device making up for disadvantages of waterpower, heat, nuclear, wind power, solar and geothermal power generation, provides a gravity power generating unit, the gravity power generating unit using the balance having the pressure load equipment as in PATENT DOCUMENTS 13 and 14 with a rotating axis of a power source of each of a waterwheel, a heat turbine, a wind power, impellent motor of a ship, solar, train and large-scale plant. The water pressure, vapor pressure are employed in the double acting single rod cylinder which is the pressure load equipment. In the wind power, solar, small-scale water flow power generation and a train, a weight, oil pressure, air pressure are used for the pressure load equipment. In addition, the water pressure of a navigating ship at a speed is used for the pressure load equipment. A load material to be most suitable for the pressure load equipment is selected, and an appropriate generator, motor are selected out of induction or synchronous power generators.
In the gravity power generating unit using balances and having the pressure load equipment which is coupled and engaged with a water wheel of water power generation, the double acting single rod cylinder is used as the pressure load equipment which is provided on right and left tips of a loaded balance. A head chamber of a water pressure cylinder on each of right and left top end portions of the load balances is communicated with a hydraulic pipe from a high-altitude reservoir, a rainwater tank or a stream, and a water pressure is added by difference in height. The water pressure becomes a force proportional to an area of the head chamber under the pressure pushing on a piston. The capacity during stroke of a hydraulic cylinder is equal to a slight discharge quantity of water, and the head chamber of the hydraulic cylinder is fixed to a frame from the ground in an arbitrary orientation. Or the head chamber of the hydraulic cylinder is fixed to the balance in an arbitrary orientation and pressurizes a frame from the ground. A water pressure force from the hydraulic pipe becomes a pressure force of the tope end of the cylinder rod through a pressure force/flow control electric operated valve, then is added on the left and the right of the load balance, and ‘places a load continuously on them. The rod chambers of the right and left hydraulic cylinders communicate with one another via a hydraulic oil tube by a closed circuit variable displacement pump. The water pressure is produced by pressurizing the hydraulic oil, and the balance is configured to automatically shift a load from one end to the other end alternately. The pressure load equipment comprises a quick opening and closing shut-off solenoid ball valve having a timer, an solenoid discharge valve in the head chamber to which the water pressure tube is connected, and an electromagnet which is provided on the leading end portion of the rod, and a control device such as a permanent magnet. Power increased by the ratio based on length of a lower load balance is transmitted to the right and the left double rod cylinders of the lower load balance. The double rod cylinder is configured to drive by the closed circuit variable displacement capacity hydraulic piston pump upper and lower, double chambers which connect upper and lower balances which are symmetrical about their fulcrums. A crank rod is provided on the upper, short-size reciprocating balance which operates at the same time and at the same place as the lower balance, the crank rod is connected to the cylinder rod, and continuous with right and left crank gears which are installed on the ground. The increased power is input into the power generator of the reciprocating hydraulic transmission unit which comprises a flywheel on an intermediate gear which is a center of the crank gear. A countershaft, a gear shaft of the power generator is coupled and engaged with a vertical a vertical axis of a large-sized generation waterwheel, and a horizontal axis of a small-sized generation waterwheel via overdrive/reduction gears. The number of revolutions is adjusted by a torque converter automatic-transmission which is a clutch. In addition, at the place such as a dam where high pressure power is provided, instead of the double rod hydraulic cylinder, double acting water pressure single rod cylinder of a water pressure double rod cylinder having an arbitrary rod diameter may be used. Both of the upper head chamber and the lower rod chamber may be constructed to operate by quantity of high-pressure water from the water pressure tube via the pressure and water flow control valve and the solenoid quick injection or discharge valve which adjust timer. In addition, oil pressure may be put in a rod chamber from a closed circuit variable displacement piston pump which is incorporated in the above multiplex oil pump. Slidability may be improved by using the water pressure and oil pressure together. In a form of using quantity of water of small-size small-scale hydraulic power generation, the pressure is low, therefore, a power is increased by loading and unloading (contact with the ground) the balance alternately according to the ratio of balances by using pressure load equipments, namely a hydraulic or a pneumatic cylinder optionally provided on the load balance or a air hydraulic cylinder, and thus increased power may be input. And the increased power moves the crank rod and the double rod cylinder (the double acting water pressure single rod cylinder) operating simultaneously with the crank rod up and down. The closed circuit variable displacement piston pump of the model which is driven with the inverter vector control motor which is an external power is constructed to switch automatically an angle adjustment forward reverse tilt plate of load sensing type at positions of top and bottom dead centers, and small quantity of oil is introduced in the upper and lower chambers. The rotating waterwheel power generator operate the motor for the double rod cylinder and the hydraulic pump which are coupled with one another, and by alternate input, water pressure and quantity of water are injected in the upper and lower chambers of each of the water pressure double acting single rod or water pressure double rod cylinder, via a flow control valve, an on-off valve which is an solenoid ball valve using a timer, and a discharge valve. The water pressure and the quantity of the water is injected in the head chamber of the reciprocating water pressure single rod cylinder of the load pressure device, then becomes a large gravity to be input according to the ratio of the upper and lower balances with respect to length of the load balance. The power is associated with increase in quantity of oil by 30% by the tilt plates of the upper and lower variable displacement pumps incorporated in the multiplex pump which is provided at a position of fulcrum, or increase in quantity of water from the water pressure/water volume control electric valve. And the number of revolutions of the power generator consequently comes into balance with the number of revolutions of the power generator operated by waterwheels. For the power generator, used is a vector control inverter synchronous power generator or an induction generator. The vector control inverter synchronous power generator is adapted for combining output by gradually adding power increased by the water pressure of the pressure load equipment to revolution power of the power generation facilities by waterwheel.
Thermal power generation using a saturation steam pressure of boilers and a nuclear power generation are main power generation facilities for commercial electricity. A double acting single rod steam pressure cylinder is applied for the pressure load equipments which are provided right and left leading end portions of the load balance. A distance of stroke is optimized to eliminate drop of an air pressure in the head chamber, thereby a slight quantity of the steam is injected or discharged. For the cylinder, used is a fluorine type elastomer seal packing which withstands saturation temperature of the steam. In consideration of heatproof temperature of a seal, a cylinder sleeve is constructed of water-cooled radiator structure comprising an air-cooling fin and a water jacket to protect the seal, while a piston rod is constructed of a radiator structure comprising a water cooling fin. A rod chamber may be constructed to lower oil temperature by operation of a closed circuit variable displacement hydraulic piston pump. In addition, the rod chamber is formed into a pipe which is open-ended and unloaded for weight saving. In the rod chamber, an attraction and repulsion forces of a permanent magnet and an electromagnet may be used. Further, in the double rod hydraulic cylinder of the reciprocating oil pressure transfer unit having upper and lower chambers of sealed structure by using closed circuits, rise in oil temperature causes leakage from the seal packing and decrease in oil viscosity, therefore the above water cooling structure is employed for cooling down the oil temperature and keep the oil temperature constant. The above-mentioned multiplex hydraulic pump is actuated by using an external vector control inverter motor. The double rod cylinders linked with upper and lower balances which are coupled with a steam turbine generator having a boiler, a crank mechanism, and a power generator connection mechanism or the like are the same as those using the above hydraulic power generation. In addition, at the place where a high steam pressure is provided, the above double acting single rod steam pressure cylinder or double rod steam pressure cylinder of water-cooled structure may be applied to the upper and lower balances at position of fulcrum. Saturated steam pressure may be applied for the cylinder head chamber, while oil pressure may be applied to the rod chamber for facilitating slidability. The steam pressure may be applied to both upper and lower chambers by using a seal packing made of fluorine type elastomer of heat resistance and good slidability as well as injecting grease. Actuation of the cylinder is switched at upper and lower dead points by a heat-resistant solenoid switching valve by means of a timer and a limit switch. The actuation of the double acting single rod steam pressure cylinders is switched alternately right and left, and associated with loading and unloading by alternate actuation of the solenoid on-off valve using a timer and a discharge valve. The steam turbine has the number of revolutions greater than that of a waterwheel. A coupled power generator is installed on the ground near the leading end of the load balance. For the coupled power generator to which torque of a power increased by a steam pressure is added from a device for gradually balancing an increased power by using a speed decreasing device and the above torque converter automatic-transmission, the vector control inverter synchronous generator or the induction generator providing an output in combination with the steam pressure generation.
A gas turbine power generator has a higher revolution rate, and is provided with a torque converter automatic reduction gear on its rear axle. A crank mechanism of a reciprocating oil pressure transfer unit and an electric control machinery of pressure load equipment are the same as those of water pressure and steam pressure power generation. For the pressure load equipment, a steam pressure cylinder which is also adapted for cooling of gas heat, a hydraulic cylinder, a pneumatic cylinder, an air hydraulic cylinder with use of a weight are used. Control devices such as a heat-resistant poppet form solenoid on-off shut-off valve, an solenoid discharge valve are provided in the head chamber, and control devices such as an electromagnet and a permanent magnet are provided on the leading end portion of the rod, thereby a pressure is applied from a steam tube to the head chamber of the pressure load chamber. And, the above oil pressure or steam pressure cylinder is used for the reciprocating oil pressure transfer unit, and the vector control inverter synchronous power generator or induction power generator, and the motor are the same as the above.
A geothermal power generation is generation by using steam pressure, therefore using nature. In the geothermal power generation, difference in pressure and quantity of steam are used. High pressure is achieved by a large diameter of a steam pressure cylinder of pressure load equipment. Used are the same double rod cylinder of closed circuit structure of the reciprocating oil pressure transfer unit and the same multiplex oil hydraulic pump as above, and the crank mechanism and other constitution were the same as above.
At present, a horizontal axis variable-pitch propeller blade is mainly used for wind power generation. With use of new Darrieus form blade equipment of the present invention, electricity production is increased. Now a group of a plurality of units of horizontal axis wind turbines are in a suitable lot, and electricity generated as a whole is applied to commercial electricity. In the new wind power station which has a plurality units of large-scale wind turbines of the new equipment, amount of power generation per unit is increased. With the use of the equipment allowing for doubled production of electricity only by a single unit, it may be considered to convert the equipment to other energy equipment such as a superconductive storage or an electricity accumulating equipment.
In a present large-scale horizontal axis propeller wind turbine, drag and lift forces from wind pressure act on a swept rotor area which is formed by three blades. Turning force of the horizontal axis may be obtained by controlling and braking variable pitch, a gear of a rotor portion of a hub is coupled with a tower central shaft via a spiral bevel gear. Here, employed is a downwind rotor system in which the rotor and a yaw mechanism of a tower spinning portion as auxiliary equipment automatically adjust orientation of a nacelle portion so as to orient the hub of a front portion of the blades in the same direction towards which the wind is blowing. A long rotating shaft which extends vertically from an interior of the nacelle to the ground, a lower portion of the tower is coupled with a horizontal axis gear power generator of an above-ground part via a spiral bevel gear or a bevel gear. Alternately, the large-scale horizontal axis propeller wind turbine is structured in such a manner that in the tower, the vertical shaft is connected directly to a multi polar low revolution permanent magnet synchronous generator, the central shaft is provided with a fly wheel on a lower portion of the shaft of the generator, thereby the central shaft is floated up and attracted by a permanent magnet and an electromagnet. An integral stress construction of the shaft and the tower is formed by a plurality of bearings of a middle portion. Or, a spinning mechanism is structured in such a manner that the nacelle and the tower portion are formed into an integral fixed structure, a yaw mechanism is provided in the portion thereof above ground, in strong winds the orientation is changed automatically while in light winds the orientation of the tower portion above ground is changed by a spinning motor with the use of a controller including a wind direction sensor. Similarly to the case with gas turbine power station and substation, the oil hydraulic cylinder, the pneumatic cylinder and the air hydraulic cylinder may be used for the pressure load equipment. The air hydraulic cylinder uses a weight installed on the ground near the left and the right leading end portions of the load balance.
an air high mud cylinder using a weight installed in a hydraulic cylinder, a pneumatic cylinder, the ground of the tip of right and left of a load balance in pressure load equipment can be employed. A force is increased according to a ratio of balances, the number of revolutions and output are changed according to the change of wind power, the fly wheel near the generator on the ground and a torque converter automatic transmission work with quantity of oil increased or decreased in upper and lower closed circuit variable displacement oil hydraulic piston pumps of the same model of machines of double rod cylinders by external motors of vector control inverters of reciprocating oil pressure transfer units, cylinder pressure force and magnetic force of the pressure load equipment are adjusted to be constant, the increased power transmits electricity to a starting motor of an external electricity in light winds and to a commercial electricity that is load in strong winds, the double rod cylinder is an oil hydraulic pump, the pump is an oil pressure motor, the external motor is a power generator, the motor just provides an output for moving up and down the weight of the pressure load equipment, and the power of increased difference is input and combined in the commercial electricity in strong winds.
When weights of the ground near right and left leading ends of the load balance are used, the output from one of multiplex pumps, a small size closed circuit variable displacement oil hydraulic piston pump to rod chambers of right and left air hydraulic cylinders is constant. And a low revolution multi polar vector control inverter permanent magnet synchronous generator is used, but a squirrel cage induction generator may be also used. A flywheel is used as an auxiliary device for wind power and gravity devices. Vertical axis wind turbines (Savonius form, paddle form) have a long history, but efficiency is not preferable compared with horizontal axis wind turbine power generators and other power generating systems. The straight bladed vertical axis Darrieus wind turbine or the like is provided with a plurality of variable blades capable of control for light winds and braking, a low revolution generating vector control inverter synchronous power generator is applied for a generator on a part above the ground. Thereby, although driving force of winds of 5 to 6 m per second or greater is required in the present system, the new system is structured in such a manner that revolutions sufficient to generate electric power may be caused by winds of 2.0/m per second or less, and power is increased by combining input of the increased power from the pressure load equipment and the wind power.
For vertical wind turbines, the arcuate Darrieus wind turbine and the straight bladed wind turbines, a variable pitch blade, a variable blade axis and a forward reverse revolution axis are applied. For right and left blades or a plurality of blades a central shaft, namely a tower portion is not provided. Right and left upper blade shafts are installed and fixed on the ground with the use of a tower structural member which is a semicircular frame member surrounding the blade shafts on three or four sides. An upper axis of the coupling structural member and an axis of a lower power generator are adapted for a main bearing portion. A plurality of, right and left upper blade shafts and lower blade shafts are entirely formed into one fit-in shaft, the fit-in shaft is fitted in and engaged with a magnetic bearing. One center shaft between center portions of upper and lower main shafts and the plurality of the blade shafts are reinforced with a horizontal reinforcing plate. The horizontal reinforcing plate and the blade plate are fixedly bonded in surface-to-surface relationship to form a bearing center portion structure in which the blade plate is flexible with respect to the blade axis. The bearing of the blade plate fixed to the horizontal reinforcing plate and the upper and lower fit-in shaft is applied to a plurality of variable control, fixedly braking, blade shafts, and an individual blade shaft is rotated by an individual oil pressure or electric motor gear to construct each of them a variable blade shaft, and the blade shaft is moved to a position most suitable for forward reversal rotation, thereby achieved is a structure in which a pitch with respect to right and left blade surface lifting force blade may be adjusted. The blade may be rotated even in light winds by adjusting the position of the blade subject to winds in the framing member, the tower. For reinforcement, the right and left blades were reinforced horizontally individually at any arbitrary position such as upper or lower center portion, and a rotation structure is constructed by receiving a blade central shaft in upper and lower reinforcing shaft which is designed slim and light-weight. The device is small-sized. Or in the structure having sufficient wind pressure resistance due to upper and lower plays of upper and lower shafts and strength of the material for the blade, any arbitrary shaft and horizontal reinforcing plate may be used. When each blade rotates by around 90 degrees, each shaft moves to the position where all blades are oriented in the direction of wind, thereby wind power is eluded in strong winds such as typhoons blow. In the straight bladed wind turbine, of straight line wing-like, semicircular frame members to be fixed on the ground are framed straight thereby forming a tower surrounding blades on three or four sides or any number of sides. Similarly to the arcuate blades, a central tower portion is not provided, separate from a central shaft of an axis bearing, an oil pressure or an electric multi rotation axis is provided, according to the number of the blade surface and the horizontal plate to be fixedly connected to the blade. A rotating shaft is provided as a large or small fit-in shaft in a center of the main shaft. Each is applied to forward reverse revolution by 90 degrees and a plurality of blades are oriented in the direction of wind, thereby wind power is eluded in strong winds. In almost the same structure as the arcuate blade wind turbine, a low revolution permanent magnet synchronous power generator, or an induction power generator is provided in a lower shaft, and a permanent magnet and an electromagnet are used in the lower bearing region, and the blade is slightly floated up by repulsion by adjusting a magnetic force, and loaded by attractive force. Self-rotation of the blade is achieved even in slight winds by using an electromagnetic bearing or a bearing for the upper bearing and employing floating structure. Thanks to the above structure for fixing the four-sided frame structure member on the ground, a wind turbine larger than the present Darrieus wind turbine may be installed on an installation area smaller than before. The size is reduced by providing a plurality of blades, and the tower and the shaft of a center axis which is reduced in diameter and weight defines an axis for receiving a horizontal reinforcing plate. The upper and lower shafts of a plurality of blades are adapted for a rotating gear axis and the structure of the blades is reduced in weight. A torque converter automatic transmission is provided on an axis of a permanent magnet synchronous power generator of a vector control inverter multi polar low revolution structure, and an intermediate gear of a crank mechanism of reciprocating oil pressure transfer unit constructed in a gravity power generating unit with the use of balance having pressure load equipment as stated above is coupled with a torque converter automatic transmission. A power of oil pressure, air pressure, etc. of the pressure load equipment on a leading end of the load balance is increased according to the ratio of balances, and the increased power is placed on the cylinder piston for pressurization by driving a double rod cylinder of a reciprocating oil pressure transfer unit with use of a closed circuit variable displacement oil hydraulic piston pump with an external electric power. An output is increased by increasing oil quantity, and it is input in a power generator. A vector control inverter motor of a multiplex oil pressure pump is actuated by switching between the external electric power and an electric power generated by wind power. The Darrieus, straight bladed, vertical axis wind turbine is structured by coupling with the gravity power generating unit using balances and having pressure load equipment for the purpose of combining the power generated by the wind power and the power generated by the gravity power generating unit to increase the power generation during drive by wind power.
In the above system, the structural member is installed fixedly on the ground with the use of the tower frame member which surrounds the wind turbine on three or four sides, and the one way rotating, arcuate Darrieus, straight bladed vertical axis wind turbine having a plurality of blades is constructed in the structural member. However, in the one way rotating wind turbine, stress such as a centrifugal force on a bearing portion will be a great burden. Therefore, the force exerted on the blades which are exposed to wind and rain for a long time period, a bearing and a fixed base is reduced by constructing an internal and an external forward reverse rotation wind turbines capable of pitch control. The distance of spacing for eliminating difference in wind speed by the arbitrary number of the blades and inner and outer blades is increased as much as possible respectively, a flywheel is provided for the difference in wind speed is changed into constant revolutions at intersection. The stress on the upper and the lower shafts is balanced with centrifugal force, thereby the burden on the bearing is reduced. This also serves to eliminate sound of winds. In two bearings on upper and lower portions of the tower, forward reverse rotating axes are applied to two of the rotating shaft for the whole of the internal blades and the whole of the outer blades. Two forward reverse rotating axes are combined to one electric generator by a torque converter reverse rotation transmission. In the inner and outer blades, a lateral pitch may be adjusted by sliding each variable blade rotating shaft in upper or lower holes in the blade plate. Repulsion and attractive force of a permanent magnet and an electromagnet which give flying force to the plurality of the blades, the weight of the flywheel and wind power, a magnetic bearing and a bearing reduces frictional resistance. The burden of the stress such as expansion and contraction, deflection and torsion due to strong wind resulted from the structure without a central tower is reduced by a play in vertical motion of the axis and entire levitation force. Each of blade shafts is a variable blade shaft, the blade shaft is moved to a position most suitable for forward reverse rotation, a right and left blade surface lift force structure is constructed, thereby a control system is provided allowing for power generation even in breeze. A directly-connected, low revolution, multi polar permanent magnet synchronous power generator or an induction power generator is used, a shaft of the generator is coupled with a gravity power generating system using balances via a spiral bevel gear and a torque converter automatic transmission of other shaft. This serves also as an auxiliary motor activated by an external electric power for start up of rotation of the blades in initial operation. The external motor of the vector control inverter of the reciprocating oil pressure transfer unit is activated by switching to an internal power generation during wind power generation.
The above one way rotation blade is in a range of a plurality of blades rotating forwardly and reversely inside and outside, as one existing technology. The present system has a structure which is fixed by a framing structural member, and is a large-scale vertical wind power generator of which production of electricity per unit is increased by the plurality of the blades. The system of simple structure having a single blade is not explained here.
A solar power generation generates electricity in proportion to the daylight hours and the number of the solar panels, electricity generated is used or stored by connecting to a commercial power supply by means of inverter control, and solar power generation is inefficient generation similarly to wind power generation, and is required to increase production of electricity in the limited daylight hours. A gravity power generating unit with the use of a balance having pressure load equipment corresponding to production of electricity of a large-scale solar power generating station is installed, and a vector control inverter power generator is constructed, and the power generator is coupled and engaged with a large-scale solar power generating station. The pressure load equipment is constructed by using an oil hydraulic cylinder, a pneumatic cylinder, an air hydraulic cylinder using a weight as in the above wind power generation. As for the closed circuit variable displacement piston pump of a multiplex oil hydraulic pump driven by the external engine of the reciprocating oil pressure transfer unit, in the solar power generation, instead of a power by connecting a power generator of the engine (water power, thermal power, wind power, water flow) and the gravity power generating unit, a power from solar power generation is used for the motor of multiplex oil hydraulic pump of the reciprocating oil pressure transfer unit and the pressure load equipment, therefore, the system is a hybrid power generating system which combines the power generated by input a power increased by the weight, oil pressure and an air pressure, and a power generated in the solar power generation. According to an existing technology, in a site where wind power is obtained, a solar power generating unit generates a power while wind power is used for power generation after sunset, in rain or cloudiness. A power generating unit is combined with the gravity power generating unit using the balance having the pressure load equipment such as a weight, thereby constructed is a complex hybrid power generating unit combined with the power wind, solar, or gravity for improving efficiency.
An oil, a liquefaction gas, a coal, an iron ore, a container carrier, a large special service ship, a self-navigation work vessel, a vessel, a submarine, or the like has a propeller shaft of a diesel engine, a gas turbine engine, a nuclear power or a motor propeller shaft from a power generator.
A large diesel engine of low or middle revolution is coupled to a gravity unit with the use of a balance having pressure load equipment on flywheels of an engine front part. A gas turbine, a nuclear power steam turbine are of a high revolution, and a propeller shaft is coupled to an intermediate gear shaft of a crank gear of a reciprocating oil pressure transfer unit via a reduction gear device and a torque converter automatic transmission. In head chambers of right and left large water pressure double acting single rod cylinders of the pressure load equipment, a high water pressure is taken through a water pipe from a bow of the ship with the use of own ship speed. When a steam pressure double acting single rod cylinder is used, each of a cooling boiler steam pressure from a gas turbine and a boiler steam pressure of nuclear power is injected in a head chamber of the cylinder via a pressure/flow rate control electric valve, only by a small quantity corresponding a short stroke, thereby a pressure on the leading end of the rod is obtained. The pressure is placed on the right and the left of the load balance, and the load is applied constantly thereto. When a high pressure force is required by water flow of self-navigation vessel, a high water pressure pump to be activated by an external motor is provided in a water pipe, and an oil hydraulic pump or a compressed air storage cylinder by an air compressor is used. In the above structure, an engine is connected directly, and a torque converter automatic gear box is connected to a power generator or a motor propeller shaft of a ship with motor propeller shaft. Pressure load equipment and a reciprocating oil pressure transfer unit are the same as in the water power, thermal power and wind power generations. In the case of a ship on cruise for a long period of time, water flow caused by the ship provides a load output, and a fuel cost is saved by increased cruising speed.
In train service, electric power, whether direct current or alternating current, which is used for operation of entire number of train services for uptown and downtown on railway routes is transmitted by a plurality of substations via overhead cables. The train services include local train service, limited express train service or the like. The electric power more than required for total number of train services is transmitted, for safety purpose. In the conventional system, regenerative electric power is not consumed efficiently by trains going uptown/downtown. An electric power consumption becomes to a maximum from when a train starts till when the train runs at a nominal velocity, will be decreased when the train operates with inertia driving force, and when a regenerative brake is used for deceleration, an electric power is returned via overhead cables to reuse the regenerated electric power is used properly, without discarding the regenerated electricity. The structure is constructed as follows. The above-mentioned gravity power generating unit using balances and having pressure load equipment is installed each substation, an inverter vector control squirrel-cage induction generator is activated by surplus electric power which is regenerated electric power, and oil pressure force is generated by operating two closed circuit variable displacement piston pumps which are connected upper and lower chambers of the double rod cylinders of the multiplex oil pressure pump of the reciprocating oil pressure transfer unit, and one closed circuit variable displacement piston pump which is connected to the rod chambers of right and left air hydraulic cylinders using oil hydraulic pumps, pneumatic pumps, weights of the pressure load equipments. In addition, the water pressure of a rainwater reservoir of a building of a substation or the like located on a high place is used. A power is increased by placing a load alternately on right and left of the balance according to the ratio of balances, the increased power increases output from increased oil pressure from two variable displacement pumps, and a generated power of the squirrel-cage induction generator of right and left crank mechanism, and a middle shaft, is transmitted to a general commercial electric power or re-transmitted to the overhead cables. Although the main purpose is to supply the commercial electric power, in this structure, since the electric power from the power increased by the pressure load equipment is returned again to the substation, the electric power to be transmitted from the main transmission line to the overhead cable is saved. The power increased in proportion to the length of the load balance is gradually discharged by a single action air cylinder of the device to which the above increased power is input gradually. The increased power transmits a power generated from the crank mechanism, while balancing with the output of the squirrel-cage induction generator, the motor by a rotation sensor of the generator and a program of a controller.
In construction of a high-speed underground electric railroad in a town area, a level track through a tunnel is constructed in a land over a public land and a private land, underground at a depth of 50 m. When total distance is supposed to be 30 km, there are five stations from a first to an end station, a distance between adjacent stations is 7.5 km, each station has three platforms for passengers, and four to six trains, connecting trains or buses can stop at the station. A distance from an underground level section to an uphill section is 1 km, and that of a down hill section is 1 km, for speed-up and slowdown sections. For a train, a high-speed low-floor rotary motor train or a magnetically elevated liner car which is allowed for acceleration up to 400 km/h on the downhill section of 1 km is applied. It accelerates at the highest speed along the downhill section of 1 km length, runs along a level section, and then slows down along the uphill section, finally stops by a platform at a station. Here, in a basic operation of a train shuttle service between the first and the end stations, the gravity power generating unit using balances and having pressure load equipment is provided each of a plurality of the stations, the electric power regenerated on a downhill braking section may be used as much as possible, thereby production of the electric power is increased, the electric power is supplied as the commercial electric power, while electric power is generated in the overhead cables. A diameter of a shielded tunnel of 6.0 m is used for a train service of standard gauge or broad gauge in a single track straight railway, that of 5.0 m for the low-floor rotary motor train and the magnetically elevated linear motor car.
When a double and straight track tunnel is divided into upper and lower parts for operation of the magnetically elevated low-floor linear motor car o in both directions, the diameter of the shielded tunnel is 8.0 m. A shielded tunnel is constructed with use of eight boring machines with shields from spots of five stations of the example, at the same time, each of the stations, and other facilities on the ground such as platforms are constructed, and it takes about three years to complete the whole system. The straight railway track section may be a tunnel section underground at depth of more than 50 m including a private land.

A flywheel (8) is provided for converting varied wind speeds to constant revolutions at intersection, a stress, a centrifugal force on upper and lower shafts are balanced each other for reducing a burden on the bearing, and are balanced with a power increased according to a ratio of balances. Two magnetic bearings (97a) on upper and lower portions of the tower serve to eliminate sound of winds by rotating two rotating shafts, an rotating shaft (107) for the inner blades, an entire rotating shaft (108) for outer blades forwardly and reversely. Forward reverse revolutions are switched and combined in one electric power generator (11) by a torque converter reverse rotation transmission (86a) of a lower axis. The outer blade (99) is not provided with a reinforcing plate, and each blade shaft (105) includes upper and lower plays (109a) for sliding (109) blade plates. For supporting weight of a plurality of the blades (99, 100) and the flywheel (8) and a floating force by wind power, repulsion and attractive forces of a permanent magnet (7) and an electromagnet (6), a magnetic bearing and a bearing are used concurrently to reduce frictional resistance. A structure without central tower is constructed, expansion and contraction of the blades and entire floating force by strong winds are absorbed in the upper and lower play portions (109a) of a shaft center, thereby the burden on the blades is reduced. Pitch is adjusted by clockwise and counterclockwise rotations of each blade shaft, the blade is rotated to a position for causing a blade lift force even in breeze, and thereby control is made allowing for power generation. A low revolution, multi polar, vector control inverter permanent magnet synchronous power generator (11) or an induction power generator (11) is directly-connected and used, and revolutions of axes of separate power generators are combined by a spiral bevel gear (94) of a torque converter transmission (86a). An intermediate gear shaft of the reciprocating oil pressure transfer unit of the gravity power generating unit (A) using the balance and having the pressure load equipment is coupled with the power generator via a torque converter automatic transmission (86).

When power is generated by wind in fair winds, the electric power is switched from an external commercial electric power to an internal wind power generated power and then used, and inner and outer forward reverse rotation blades are combined. The vertical axis Darrieus wind turbine generator or the straight blade wind power generator is coupled with the gravity power generating unit using balances and having pressure load equipment, thereby the hybrid power generating system is constructed. That is, according to the present invention, a plurality of inner and outer blades rotate in forward and reverse directions, respectively, wherein a generated power is remarkably increased, thereby a stress on the bearing portion of the tower and the like may be decreased, and the vertical axis wind turbine may generate an electric power depending on the number of the blades, compared to the existing horizontal axis wind turbine.

The gravity power generating unit is adapted for increasing a power according to a ratio of two step, upper and lower balances, and for inputting the increased power in the solar power generation of the large size solar power generating station. In solar power generation, a power is generated in proportion to daylight hours and the number of the solar panels (110), the generated power is connected to a commercial power supply (111a) and is stored in a power storage system (112) by means of inverter control, and since the daylight hours are limited, and solar power generation is required to increase production of power within the limited hours. A multiplex oil hydraulic pump (14) used for the pressure load equipment and a reciprocating oil pressure transfer unit is activated by a motor (12) which is driven by an external electric power. For the pressure load equipment provided on a leading end portion of a lower load balance (1) extending to the right and left, a water pressure cylinder by obtaining a water pressure from a high place, a steam pressure cylinder in a place where steam pressure is available, an oil hydraulic cylinder (9c) of an oil hydraulic unit (79), a pneumatic cylinder (9d), or an object which supports weight of the weights (10b) on right and left leading end portions of the load balance (1) by the air hydraulic cylinder (9c) may be used. Any one of them repeats loading and unloading alternately on the right and the left of the balance. A power is increased by the pressure load equipment according to the ratio of balances, and the increased power is transferred to right and left double rod oil hydraulic cylinders (3a) which are connected and linked to an upper reciprocating balance (2) at a fulcrum position. For the multiplex oil hydraulic pump (14) a vector control inverter motor driven by the external electric power is used. The double rod oil hydraulic pump (3a) is driven by two closed circuit variable displacement piston pumps of the same model which are provided between the upper chambers, and between the lower chambers, respectively. An alternate output of the water pressure, the steam pressure, the oil pressure or the air pressure from one small size closed circuit variable displacement oil hydraulic piston pump (27) provided between the pressure load equipments, or an alternate output into right and left rod chambers of the air hydraulic cylinders is constant.

A power increased by loading is placed alternately on pistons of right and left double rod cylinders (3a) in which volume of oil is the same between the upper chambers, and between the lower chambers, thereby pushing the pistons. With refill of hydraulic oil by an auxiliary pump (26) an output of the power generator (11) is gradually increased via intermediate axes of right and left cranks which are coupled and associated with the reciprocating balance, and the output of the power generator is combined with the solar generated power by a power conditioner (53). In hours without sunshine, such as nighttime and rainy day, the gravity power generating unit (A) using the balances and having the pressure load equipment is driven by a vector control inverter motor (12) which is activated by an external electric power, and functions as a solo gravity power generating unit or as a power generation unit constructed by combining the gravity power generating unit (A) and a wind turbine power generator, a power from each pressure load equipment is increased according to the ratio of balances and input in the gravity power generating unit (A).

In a combined power generating station, a power is generated mainly by solar power generation in unpredictable sunshine hours in daytime, and the power is combined by connecting the power conditioner (53) of the solar power generation to unpredictable wind power generation. A low revolution multi polar vector control inverter permanent magnet synchronous generator (11) capable of corresponding wind power strength is used. During either of solar power generation or wind power generation, an external electric power is switched to an internal electric power. By a revolution output of the wind turbine power generation, the double rod cylinders (3a) act as oil hydraulic pumps, the oil hydraulic pumps act as oil hydraulic motors, an output of the motor (12) is applied just as an output for moving up and down the weight (10b) of the pressure load equipment, and the power of increased difference is input in the commercial electricity, thereby combined electric power is provided.

The pressure is placed on a right and left of the load balance so as to be applied thereon constantly. Water is discharged while steam is circulated. A high water pressure pump (4b) to be activated by a motor (12) is provided in a pressure water pipe, thereby water flow of the self-navigation vessel is made at high pressure. For the reciprocating cylinder, a double rod oil hydraulic cylinder (3a), a double acting double rod water pressure cylinder, or double acting single rod water pressure cylinder (3b) is used. Oil pressure is applied in a rod chamber of the double rod cylinder. Used is the double rod cylinder in which oil pressure is applied in a rod chamber and water pressure is applied the other rod chamber, while used is the double acting single rod cylinder in which the water pressure is applied in the head chamber, and the oil pressure is applied in the rod chamber. The stroke is associated with a crank (15), and operating directions of the pistons are switched alternately between the right and the left cylinders by a switch (34) at upper and lower dead points.

That is, in the high-speed underground electric railway of the present invention, a public land in a city area is used. For a high-speed train service, stations on the ground are connected by a straight track, single-track, deep underground shield tunnels of small diameter are employed, therefore, the undergrounds of private lands are necessarily used. Each section between adjacent stations comprises the same uphill and downhill zones and the same level zone. A regenerated power is input in the gravity power generating unit using the balances and having the pressure load equipment capable of efficient use, then increased power is fed to overhead wires. Safety equipment is provided to primarily operate in case of tight transport schedule.
According to the invention of claim 11, a hybrid power generating system for coupling a gravity power generating unit using balances and having pressure load equipment, and a high-speed underground electric railroad service in land over a public land and a private land such as a town area, under bottom of the sea, or the like, as set forth in claim 10 are improved. A plurality of platforms (126) are provided at each station of the starting station, the terminal station and a plurality of the intermediate stations, a deep underground single track tunnel is provided in each section between the stations, each of the deep underground single track tunnels has a structure of the same distance, the same downhill and uphill zones, a level zone of the same distance and depth, and the deep underground single track tunnel may be a small-diameter shielded tunnel.

A service of the magnetically elevated low-floor linear motor train (118c) uses an aboveground station having two-storied, upper and lower platforms. The magnetically elevated linear motor trains (118b, 118c) operating on a single and double tracks are accelerated to the maximum speed on the downhill zone, and a regenerated power by a regenerative brake used in the zone is input in the vector control inverter motor (12) of the multiplex oil hydraulic pump (14) of the gravity power generating unit using the balance and having the pressure load equipment, via each control device of a substation facility (111), as a driving electric power. A generated power of the vector control inverter power generator (11) is transformed again to an alternate current high voltage and fed to overhead cables or transformed to a commercial electric power, by a structure similar to a low-floor rotating motor train (118a). The magnetically elevated low-floor linear motor train (118b, 118c) is driven by using an alternating current high-output vector control inverter VVVF induction linear motor. When each distance between stations is longer and higher speed is required, a superconductive elevated linear motor train is employed. The high-speed underground electric railroad service comprises the small diameter deep underground tunnels. That is, the linear motor train service according to the present invention does not require mutual exchange with other railway companies. The linear motor driven train may be sized smaller than a rotary motor driven train. Magnetic elevation or a specification of wheels is selected in an arbitrary manner. The magnetically elevated linear motor train which may be small-sized may be applied for double track which is constructed by dividing the shield tunnel into upper and lower parts. This is a merit of the magnetically elevated linear motor train. The superconductive elevated linear motor train may be employed for transportation on a section of 10 km or more between stations, specifically for transportation between airports, etc. which requires ultra high speed.
According to the invention of claim 12, a high-speed underground railway service, as set forth in claim 10 is improved. A passenger step used by passengers is adapted for facilitating swift, safe and sure boarding and alighting, An internally threaded portion is formed in a lower portion of a housing portion of a sliding door (131), side portions of the step (130) on right and left portions contacting with a floor of a body of a train is adapted for bearings (133b), right and left externally threaded shafts are fitted in the internally threaded portions, then the shafts are connected to right and left portions of the step (130), the internally threaded portion (133) rotates the externally threaded shaft (132) about an axis along with opening and closing of the door, thereby the step of a proper width contacts a floor of a platform, the step is provided with a play as counter measure against shaking of the train, and the passenger step has a simple and sure mechanical structure for being stored in front of the door and extended to contact with the floor of the platform repeatedly. Alternately, in a train having cars which are configured so as to define generally constant gap and level difference relative to a platform along an entire length of the train cars, provided is a mechanism which is actuated by using an electric, pneumatic apparatus for extending the passenger step (130a) from an underside of a floor adjacent to a door and retracting the passenger step (130a) therein, cooperating with opening and closing of the door. Two types of step equipment (130, 130a) comprise a metallic portion and an elastic material such as rubber or plastic for eliminating the gap (134) and the level difference between the platform (129) and the floor adjacent to the passenger door. The passenger step is non-slip, and has proper width and thickness, thereby the passenger step is structured so as to allow passengers with a large carry-bag or a baby baggie, a passenger in wheelchair, or a handicapped passenger for getting on and off the train surely and safely. The passenger step may be applied for the linear motor train, an aboveground street car or a route bus. The high-speed underground railroad service is provided with the passenger step (130, 130a) for allowing reduction in boarding and alighting time surely and safely in a high-speed train operation. That is, in an existing railway service, a station staff brings and sets a step for wheelchair passengers as wheelchair passengers board and alight the train. The boarding and alighting time depends on the number of passengers. The travelling time consists not only the train's driving speed. The passenger step of the present invention facilitates smooth boarding and alighting of the passengers, thereby the boarding and alighting time is reduced.
According to the invention of claim 13, a high-speed underground railroad service, as set forth in claim 10 is improved. Handrail stands are provided for facilitating smooth flow of passengers getting on and off a train which stops at a station. Since the train departs from a station at 3 to 4 minute intervals and operates through tunnels in a short time period, no window is required. In a low-floor rotary motor train (7), a portion such as a floor which covers wheels is used for the required number of seats (119, 119a) for the handicapped, in a magnetically elevated low-floor linear motor train, each air conditioner, control device or the like to be disposed in a ceiling is positioned under seats on a side wall which contacts with the floor, a rest of the floor is not provided with seats, instead, hand straps or the like are provided, and hand rails on right and left side walls (137b) (hand rest) are provided, and two rows of the handrail stands (137) are provided on a center portion of the floor, in parallel relation to the side walls, or on the floor in parallel relation to the side walls. The proper number of the handrail stands (137) having proper length roughly at waist height are provided at positions except for those near passenger doors (131, 131a), or a portion of a floor which does not disturb passengers from boarding or alighting, the handrail stands (137a) in place of seats are provided perpendicular to the direction of travel. Since the handrail stands (137a) are roughly waist-high, a passenger is allowed to lean his body on the handrail stand, while holding the strap with his hand, thereby the passenger may be prepared for acceleration during travelling at high-speed, the high-speed underground electric railroad service which are provided with the handrail stands by eliminating seats for facilitating smooth flow of passengers boarding and alighting may be applied to a commuting train, vehicle for the handicapped, or route bus. That is, in an existing double track train service, seats are required, but in a crowded train, even space for the seats appears bothersome. When the seats are eliminated in the train having windows, the windows become a nuisance. In a compartment where windows are eliminated, passengers lean on walls, a wide space is left on a floor, then handrail stands are required on a center portion of the floor, accordingly, the handrail stands (19) are provided in one or two rows in the compartment. The handrail stands have a length suitable for smooth flow of passengers.

The embodiments of the present invention are explained based on drawings and reference numerals.
At start, operation is performed in such a manner that a power is increased according to the ratio of balances with the use of pressure load equipment, and the increased power is supported by air pressure which is filled in single acting air cylinders (5). At the same time as operation, a timer (38) is adjusted, discharge time from a discharge valve (75a) is set, a device to which load is gradually input and a vector control inverter motor (12) are rotated by lowering output in order to balance with electric load output of a power generator. Through discharge of air pressure little by little and lengthy action of increased oil quantity of a closed circuit variable displacement piston pump (25) of a reciprocating oil pressure transfer unit sensing a load, the increased power is returned to a nominal output while the load output of the motor (12) and the load output of the power generator (11) are balanced. An oil pressure, a water pressure and a steam pressure are basically the same (in function), and the following embodiments will be explained for whole of them according to specifications of the above equipment, etc.
Each of solenoid on-off shut-off valves (67, 67a, 67b, 74, 74a, 84), solenoid switching valves (70), solenoid discharge valves (68, 68a, 68b, 75, 75a, 85), steam pressure solenoid switching valves (85a, 85b), electromagnets (6), relays (37), digital timers (38), exciter devices (39), limit switches (34) as illustrated in
When saturated steam pressure of a large volume of steam pressure is obtained, natural discharge is possible because the steam pressure is an air pressure. An oil pressure is not required in a rod chamber. For the cylinder, a fluorine type elastomer seal packing having heat resistance to about 200° C. and water resistance is employed. Such heat-insulated structure is employed that an electromagnet portion and a spool portion of each solenoid on-off valve and discharge valve are separated into two, and these are coupled with one another by steel spiral springs with radiation property. In order to take a countermeasure against leakage of a sliding portion of the spool, the above seal packing of the fluorine type was used. The sliding resistance of the seal packing of each of the oil pressure, the water pressure, and the steam pressure and other mechanical resistance become heavy load. By virtue of the excellent accuracy of hard chrome plating, etc. and the long lasting durability of the seal packing, etc., leakage from a dust seal (63), a piston seal, a rod seal is almost zero, in particular in closed circuit double rod oil hydraulic cylinder, single or double rod water pressure cylinder, steam pressure cylinder, or the like. In order to achieve similar accuracy with respect to a pump, a pump of higher rank is used.

With regard to horizontal wind turbines, those of large-size are employed as mainstream. However, a size is limited because of a turbine structure and a nacelle power generator having a tower, and solar, wind power generating systems depend on natural forces, therefore is inefficient compared to thermal, and water pressure power generating systems. The wind turbine power generator of the present invention is constructed in such a manner that one of vertical axis wind turbine power generators having a power generator on the ground, a Darrieus wind turbine power generator is formed into a multi polar, low revolution, vector control inverter synchronous power generator, in spite of the structure of blades which require a driving force by a wind power of 2 m/s or more, and a construction comprising variable pitch blades, a plurality of blades, an a forward reverse rotating blade axis, and input from balanced construction of an increased power from the pressure load equipment and a fly wheel allow a power generation which can be driven even in wind power 2 m/s or lower, therefore, the wind turbine power generator of the present invention is more efficient than a horizontal axis wind turbine power generator.
An arcuate Darrieus wind turbine comprises outer blades only, two right and left arcuate blades or a plurality of blades, and rotates only in one direction. A center axis and a tower portion are not provided, and a structural material is fixed on the ground with a semicircular frame member (98) surrounding right and left upper blade shafts on three or four sides. An upper magnetic bearing (97a) and a lower magnetic bearing (97a) of a coupling structural member are adapted for a center bearing portion (107), as illustrated in

The adjacent stations are connected with a straight track, an uphill and downhill slope of the same inclination of the same inclination is repeated alternately, required time for passenger interchange is about 1 minute, and a train runs on a route of 30 km, from the starting station to the terminal station, five stations away from the starting station, in twelve minutes. Velocity along a straight course is 300 km/h, namely 5 km/minute, an inclination angle of a downhill course of 1 km is 20 to 1, and acceleration time period is about 20 minutes. Each uphill course until when the train stops is the same in inclination angle and distance, the train runs along the uphill course of 1 km in about 40 seconds, decelerating from 300 km, and it takes 2 minutes for the train to run all the way of 7.5 km. The train runs along the regenerative brake zone of the downhill course in about 10 seconds, and the regenerative brake is properly used during uphill run, and it is almost offset with generating energy during downhill run. The gravity power generating unit is adapted for increased power is converted to power generation, and the power generated may cover most of electric power required for acceleration and level and inertia operation of a train.
And, in about 5 seconds after starting along the downhill course of 1 km and inclination of 1/20, and at a point of 100 m from a start, the train accelerates to about 150 km/h, in about 10 seconds, at a point of about 300 m to 400 m, the train accelerates to 400 km/h under an action of potential energy, and the rest of the downhill course of 700 m of travelling time 10 seconds is adapted for the regenerative brake zone. The train decelerates average velocity to 300 km along a level course while regenerating power, along the uphill course to the next station the train runs with inertial driving force, without deceleration. Regenerated electric power of a plurality of inbound and outbound trains is returned to each substation equipment (111), and this intermittent electric power as described in detail in Japanese Patent No. 4367795, etc. is input in an vector control inverter, three phase alternating current, six polar, squirrel-cage induction motor (12), 10,000V, about 5,000 kW/h of the gravity power generating unit (A) using balances and having pressure load equipment in which a flywheel is provided, and the squirrel-cage induction motor (12) provides driving power to two closed circuit variable displacement piston pumps (25) of a multiplex oil hydraulic pump, between upper chambers and between lower chambers of double rod cylinders (a) of the aforementioned reciprocating oil pressure transfer unit, as illustrated in
According to one of ideas of train services, a travel time required for adjacent stations including passengers interchange is three minutes. Two trains (pair train service) departing from a starting station, a first station (123a), arrive at the next station, a second station (123b) in six minutes, two trains which wait at the next station immediately start for the starting station (123a) in the opposite direction. And initial two trains departing from the second station arrive at a middle station, a third station (123c) in six minutes, while two trains waiting at the third station (123c) depart from the third station, arrive at the second station in six minutes, and wait at the second station. When two trains depart from the third station and arrive at a fourth station (123d), two trains waiting at the fourth station depart for the third station. The initial two trains are to depart the fourth station for a terminal station, a fifth station. The trains which arrive at the third station from the starting station, the first station, and the trains which arrive at the third station from the terminal station, the fifth station, will depart from the third station simultaneously. The third station is located at center of the total distance, at the same distance from the starting station and from the terminal station, and is an important station where inbound and outbound trains wait for adjusting departure time. When a person gets on a train, timing departure time of trains which depart a station prior inbound or outbound two trains, he/she arrives at the next station in three minutes. If he/she misses his/her intended train, he/she can take a following train and arrive at the next train in 6 minutes. The travel time between two stations is six minutes, and that from the starting, first station to the terminal, fifth station is 24 to 25 minutes. In operation with single train in a three minute interval, the travel time is a half, twelve minutes.
In the express railway service here, the rail gauge is a standard or wider gauge, the number of cars in a train is decided on corresponding number of passengers, and each of parts, components, and the like is as per common specification as other railway trains. Light-weight aluminum alloy is used, and a low-floor train (118a) which travels stably during acceleration to high speed.
In order to deal with travelling along the downhill acceleration zone, right and left handrail stands (137), and hand straps are provided. Windows or the like are not required since a train operates in tunnels, width and position of a passenger door, etc. is freely designed. The single railway line and aboveground stations are housed in buildings. A small-diameter wind shielding tunnel does not allow birds, dogs, cats and the like. Counter measure against accidents, etc. must be perfect. Instructions are given by control station, confirmation of safety equipment of each tunnel is instructed, and operators of trains between two stations cooperate and confirm each other. When one train starts after stops, power source of the other train automatically turns off. As such, secondary and tertiary safety structures are provided. Considering emergency stop in a tunnel by earthquake, evacuation on foot from a railway tunnel, etc., the train service is provided with full-scale preparations such as battery facilities, ventilation facilities, and water pressure pump for water seepage, humid, humidity, flooding, etc.
The cost for excavation of a single track tunnel is lower than that for excavation of a double track tunnel. Even allowing for the increased cost in providing two more platforms at each station, the related cost such as cost for purchase of private land, cost for seeking permission for underground construction, is saved by using deep underground. A straight railway service which appeared to be impossible is now possible, a travelling time is now short, and an electric power to be consumed is almost supplied by the gravity power generating unit (A) using the balances and having the pressure load device installed. Each station has a hub function. Since the present railway system is different from existing railway services, mutual exchange is not possible, but a passenger may change from a train to other transportation such as bus at the platform, or the train service cooperates with other transportation service such as route bus service as much as possible on convenience for passengers’ to transfer transportation means. The present train service provides a single track railway operation which allows a train to operate along one section in three or four minutes.

This is not limited only to the high-speed underground electric railway of the present invention, when a passenger cars of a train stops, a gap (134) and a level difference defined between a floor adjacent to a passenger door and a platform (129) varies among railway companies. A passenger step of a train in
A cylinder (136) of pneumatic equipment or motor equipment used for a pneumatic brake for stopping or decelerating a train is provided under the floor or in the door housing portion. Closing and opening action is associated with forward-and-backward motion. In the single track, straight railway service of the present invention, all floors have constant height while all of the trains have floors of constant height. In such case, the step of a thin flexible metal plate, or hard rubber or plastic materials and the like may be extended from or retracted in a mechanism for opening and closing the door. Although this is not limited to a high-speed train, the passenger step may be integral with a side surface of the car body, not to be subject to the wind pressure. And, the step may extended before the door is open, and retracted upon closure of the door, by this construction, the structure for avoiding the wind pressure may be constructed.
In
A power increased from load of pressure is gradually input during the time from start-up to normal operation, load output of a power generator driven by output of a motor of an external electric power must be balanced the increased power, under control of a vector control inverter by a programmed controller (53), and is also balanced with one of load outputs, motor devices, etc. under control, and thus operation is continued.

Accuracy (shockless property) of leakage free solenoid on-off, discharge, switch valves is important. When in and out timing of solenoid valves are controlled through relay via a timer, response is slow. In and out timing of the solenoid valves are controlled by high-performance digital timer, up and down movement is switched to cause inertial rotational movement of a flywheel, a power increased by rotation caused by smooth switching generate pressure and rotational movement.
As explained above, a power (weight) itself has no energy, and fossil fuel itself is not energy. Both are converted to energy by assisting actions from other substance. The increased power of the equipment is placed on fluid of closed circuit, oil hydraulic, water pressure, or steam pressure apparatus, pressurized, and converted to pressure by loading and unloading (contacting with the ground) by right and left portions of a balance constantly. Depending on magnitude of an auxiliary energy of this external driving power (water pressure, steam pressure, engine, motor), pressure of the pressure load equipment, size of each equipment, and energy to be obtained are decided.
Water pressure from a high place is not always available. It takes cost for managing facilities. Wind power generation is not reliable power source equipment, because a place for installment is limited, wind power difference among spring, summer, autumn, and winter, and sometimes it is calm. Solar power generation depends on average day light hours. In a hybrid power generation where equipment of the present invention is combined, consumption of fossil fuel is reduced due because of supply of energy, a superconductive flywheel equipment, etc. is installed in a facility for storage, a high performance rechargeable battery is charged, or a hydrogen is filled at high-pressure via electrolyzation, thereby it may be one of systems for controlling unreliable natural energy. It may be applied for power generation for areas of agriculture and fishery in primary industries in the future, and equipment/facility of important water supply.
Energy which is unrecognized and unused is discarded. Since fossil fuel is used easily, resulting in accumulated air pollution. In particular, pollution by carbon dioxide gas and petroleum chemical substance, and radiation contamination in the worst case, is a matter of an earth environment and creatures' survival at present and in future. Although there are many means for taking renewable natural energy, there are a few means for taking in all of power from movement around us and taking its kinetic energy efficiently. According to the present invention, there is provided a gravity power generating unit using balances and having pressure load equipment which is provided with means for obtaining a potential energy from the movement and means for converting it from a mechanical energy to an electric energy. Consumption of energy from the present fossil fuel will be limited in near future. The energy policy for the future must be reviewed soon, to convert economy of consumption to economy of environment, to reduce consumption of fossil fuel by half, and reduce exhaust of contaminated substances.
Efficient means for storing required energy is limited to a battery, a flywheel for a short term, and water pumping to a high place for a long term. One of such means is the equipment of the present invention for converting means for increasing power to water pumping force. The equipment of the present invention comprises pressure load equipment for increasing power in large diameter cylinders using water pressure of the high place. The further increased power according to a ratio of balances, is placed on up and down strokes (in large-size equipment, strokes of a double rod chamber correspond to diameter of a cylinder) of double rod water hydraulic cylinders of a reciprocating oil pressure transfer unit. A discharge of the large cylinder is a slight amount of water (stroke of about 10 mm of a head chamber). An amount of water of an water hydraulic rod chamber is also slight, therefore an oil hydraulic rod chamber requires very small capacity of sliding and timing adjustment. Input from an associated crank to a power generator generates driving output for a water power generating station. According to one of plans, in a large-size water resource of a dam, water is shared by water pipes (water pressure pipes) for city water, water for power generation, and farm land. An amount of rain water to be stored is larger than an amount of water which is consumed by a power station of the present equipment. Therefore, it is allows for constant water power generating station which require the water pressure and a slight amount of water. In a dry season, an amount of water required for the farm land may be obtained by pumping groundwater by inexpensive electric power. Inexpensive electric power finally leads to industrial, agricultural or fishery products, therefore equal to storage of energy.
A major purpose of conventional water power generation is for temporary power generation by using large amount of water which has been pumped up with the use of night power. Unlike the conventional power generation, when a power station of the present equipment is employed, water flow is increased in a downstream area, inexpensive electric power is available by constant power generation, and agricultural water is available constantly. This changes necessarily forms of agriculture, increases amount of water in the downstream area, and increases marine life (such as phytoplankton) in the sea of this area. And, the hybrid power generation station of the gravity power generating unit using the balances and having the pressure load equipment will bring the result of restored natural environment and therefore increased productivity of agriculture and fishery.
In a large ship, pressure caused by water flow caused by the large ship increases cruising speed by 30%, and this saves fuel cost. In a vertical axis wind turbine (such as Darrieus wind turbine), by a mechanism of pitch adjustment and variable rotating shafts with the equipment of the present invention, power is generated even in slight winds, and control and braking in strong winds may be secured. And, in a high-speed underground electric railway service which comprises deep underground small-diameter shield tunnels, a plurality of stations on the ground, and straight sloping tracks of the same distance and the same inclination therebetween, an electric power which is regenerated by braking during downhill run of rotary, linear motor trains at super high speed, this allows for energy saving travelling of trains.
