The invention concern a method for making an optimal working of a power machinery of waves.—Where the machinery or the apparatus consist of one or more upright standing legs, with an integrated arrangement of pistons for transmission energy.
Hitherto is known power machinery of waves, as an example described according to the French document of patent no. FR 2607870 A1, where this machinery has an upright standing leg, and where the leg in the same time is a cylinder with a piston, and where the arrangement of piston via a floating arrangement transmit the movements of the surfaces of the sea, both for the up-going as the down going movement for a hydraulic pressure via more arrangements of valves.
The disadvantages by this arrangement is that one usually use the up-going movement of the floating as power source, which is opposite the direction of the force of the gravity, why the own weight of the floater in some grade, and the hydraulic power take-off in specially grade limit the possibility of the floater for lift, and by this, the size of the power take-off.
By the invention one want to procure a power machinery of waves with up-standing legs, and with, in this, integrated pressure cylinders and pistons of the mentioned sort, where one with a new method of working, and an apparatus for this, now transmit and pick up a greater part of the coming power of waves to the arrangement.
The new is that the energy, which has to be produced, is produced in the legs, by and in the down-going stroke of the power machinery of waves.
The own weight of the float and the force of the gravity can very easy defeat the resistance from the tapping means of the hydraulic power, why this do not have any influence at all.
In the stroke of the suction, in the up-going movement of the waves, the heighten pressure of sucking in, make a pressure on the piston of the cylinder, which of course have a bottom contact. And the counter pressure will therefore lift the float, because the cylinder is mounted on or at to the float.
The float get in such a way help in its up-going movement, and it will moreover get, according to the pressure, a higher energy of level position.
The new is also, that there in one working operation for making or getting power energy by the arrangement has to be establish a heighten pressure of sucking in, which has to be accumulated in the belonging tanks for the power machinery of waves. And where the accumulated pressure itself has to be made of the energy producing stroke of the cylinder.
One obtain by this that the arrangement establish a heighten sucking in pressure qua the accumulated pressure, which has to be made of the energy producing stroke of the cylinder.
The new is also that the piston rod in the integrated piston arrangement is placed freely or loose on the bottom of the sea, and where the cylinder itself, and for this, is mounted on a float, and where the piston rod in this combination works as counter hold leg. As there at the end of the piston rod against the bottom is mounted a movable and yielding presser foot or a ski, which in its plan of foot—or ski continuous follow the surface of the bottom of the sea.
One obtain by this that the presser foot get an optimum supporting and counter holding for its pumping function via the arrangement of the piston in the leg.
The new is further that the vertical standing leg with the integrated arrangement of piston is equipped with a glide—and couple pipe for coupling and guiding of the lower part, as the upper part, of the vertical standing leg, for a continuous contact and a counter hold against the bottom, and by this a functional contact for it now working arrangement of piston.
One obtain by this that the counter hold system as the pumping system has to be coupled infinitely gliding together, in such a way that the distance between them can be extended or shorted. But where one still get the proportions and the conditions for an optimum pump function.
The invention shall after this be explained nearer according to reference of the drawing, where
The leg itself 11 and 8, here named as the counter hold leg 11 and 8 consist of two parts, namely a under water part 11, named as the under water leg 11, and a upper water part 8, named as the hydraulic cylinder 8.
The under water leg 11 is limbered up by pressure strong cardan joint 4, made of strong material, and with strong bearing sleeves 4A, which is welded for a fixing.
The underwater leg 11 has a double conical step foot 1 with haul up—wire-eyes 2 for up hauling wires 3.
The under water leg 11 is guided through the float in the sliding pipe 5. The upper water part/the hydraulic cylinder 8 consist of cylinder 8, with piston 10 and a piston rod 10A. The cylinder 8, which has ventilation hole 9, is mounted 7 to the deck 14. The ventilation hole 9 prevent vacuum and compress in the cylinder 8 under the piston 10. Under the installation the under water leg 11 has to be bolted together with the piston rod 10A, by which the piston 10 get contact with the bottom of the sea 17
The counter hold leg is loose standing on the bottom of the sea 17.
The sliding pipe 5 is going through the float and is fixed mounted to this.
The sliding pipe 5 has welded up pulled pipes 3A, and mounted wire up pulled winch 6, which regulate the extract of the under water leg 11.
The sliding pipe 5 has sliding end bearings 5A, which have to be greased from grease nipples 5B.
Of more components to the power craft machinery of waves according to
In the up going movement of the waves the volume of the cylinder 8A has to be raised over the standing still piston 10, because the float with the mounted cylinder 8 has to move up.
Because of that there are getting a different of pressure, which automatically open the one way valves 1, 2 and 3 and automatically close/stop the passing through from the one way valves 4, 5 and 8.
The loading pressure of the stroke of the sucking in is the throttle control of the float, because the size of the production is depend of this.
The loading pressure are secured the contact of the counter hold leg to the bottom of the sea.
The loading pressure has to be regulated by using of manometer 16, the means of air pressure supplying 17, the regulating screw of the pressure 18 and drain cock 19.
Position 20 is a safety valve. The loading pressure has to be established by larger quantity of hydraulic oil from the lover pressure tank 11. And with this a lesser, but a pressure giving lot of oil from the high pressure tank 9A.
The quantity of oil has to be regulated by an adjustable closing cock 21. The oil stream has to be gathered in a lead 13 of 3-way-coupling.
The volume of the cylinder 8A over the standing still piston 10 has to be reduced, because the float with the mounted cylinder 8 move down.
Because of that arise there a different of pressure, which cause automatically opening of the one way valves 4, 5 and 6, and automatically closing or stop of the passing through from the one way valves 1, 2 and 3.
The energy tapping has by this to be transmitted to the high pressure tanks 9A and 9B, by which the air mass/air pillow has to be pressed together.
The pressed air pillow 12 accumulate the pressure energy for use for a smooth pressure of oil to the hydraulic engine 14 and generator 15, which produce electricity.
The arrangement of power machinery of waves is mounted on a float of the type “point-absorber”, and have to be placed on open sea with slack mooring.
The weight of the float is adjustable with the water ballast in tanks.
The float produce electricity from power of waves by taken out of energy i the down going movement of waves, where the own weight of the float and the size of the wave is factors in the account of energy (power×way).
The tapping of power has to be done by free on the sea bottom standing counter hold leg, guided through the gliding pipe of the float, and following bolted together with the rod of the cylinder piston.
The hydraulic cylinder is a single working, with a hole of ventilation in the lower part, and it will be mounted to the float.
The under water part of the counter hold leg is done ductile by strong cardan parts, made of strength material.
The under water part has tread foot, double conical made, and with hauling up eyes for hauling up wires.
The gliding pipe is mounted on the float, and consist of a strong pip with greased end sleeve bearings, and have welded on, up hauled pips for up hailed wires.
Capstans will regulate the length of the extraction of the counter hold leg.
The hydraulic system of the float consist of: Hydraulic cylinders, high pressure tanks, low pressure tanks, hydraulic engine and generator.
The pressure tanks have air mass/air pillow, which under the power taken out will be pressed of the hydraulic pressure, and by this accumulate the power of the pressure for use for an easy and regulating power supplying to the hydraulic engine and the generator.
The pressure tanks is equipped with: Manometer, safe valves, adjustable closing valves for all connections of pipes to/from the pressure tanks, water draining valve, means for receiving of air pressure and air screw for regulation of air pressure. The raised charging pressure has to be done of a larger lot of hydraulic oil from the low pressure tank I, and a lesser lot of pressure giving hydraulic oil from high pressure tank 9A, gathered in a 3-way connection of pipe to the hydraulic cylinders.
In the cycle of operation itself is it the float, and one to the float mounted cylinder, which working up and down, around the constant standing still piston with contact of the sea bottom.
The arrangement has to be started up via the pressure tanks (air pressure).
