The application claims the benefit of China application serial No. 202210240630.0, filed on Mar. 10, 2022, and the entire contents of which are incorporated herein by reference.
The present invention relates to a method for providing green energy and its device and, more particularly, to a method for generating electricity using gravity, a gravity-driven electricity generating device, and a power unit thereof.
In recent years, with increasing awareness of environmental protection, many countries have promoted reduction in non-renewable energy one after another and actively devoted to development of renewable energies. Renewable energies include natural energies, such as solar energy, wind power, hydropower, waves, ocean currents, tides, etc. However, each of the above renewable energies is limited in the field of installation and causes certain destruction and interference to the natural ecology. Furthermore, most renewable energies require large or complicated equipment which is expensive. Thus, considerable expenditures are required in development and production of energy as well as maintenance.
Of more importance, the renewable energies use natural energies as the power for generating electricity and, thus, may encounter periodic change in the strength of the natural energies or unpredictable sudden natural disasters, which is one of the factors resulting in failure in continuous stable generation of electricity by the equipment. Thus, current equipment can only intermittently produce energy or requires development in the compensation mechanism of off-peak production capacity and development in the protection mechanism such that the equipment is difficult to damage in extreme environments. The above factors cause problems of high costs of the equipment for producing renewable energy or difficulties in increasing the production capacity.
On the other hand, the concept of “gravitricity” has been researched and proposed in recent years, which uses wasted drilling platform and wasted mines. In a well with a depth of 150-1500 meters, a rig of a length of 16 meters can be repeatedly lifted and lowered. Namely, the rig is firstly lifted to a position above the well by an electric winch. When it is desired to use electricity, the rig is lowered to release the stored electricity. The concept is similar to a pumped-storage power station. Another type of gravitricity equipment is disposed on the ground and has a height of about 35 stories. Furthermore, a super large crane disposed on top of the equipment can stack concrete bricks of 35 tons on the top floor of the equipment in advance. When it is desired to use electricity, the crane moves the bricks to the bottom to actuate the generator by potential energy. However, the above two gravitricity equipments are extremely huge and, thus, disadvantageous to installation in the city. Furthermore, a considerable amount of energy is consumed in lifting the jig or concrete bricks. As a whole, it is not a good idea in “producing energy”, though it is an “energy storage” method.
Furthermore, products using similar concepts have come out, such as a gravity light. A user spends a few seconds to pull a string tied with a weight block to a top end of the device. Then, the weight block pulling the string drops slowly under the action of the gravitational force. During this process, a generator is driven to generate electricity, converting a portion of the gravitational potential energy into electrical energy, such that the light emission lasts for about half an hour. Although the gravity light is an example of application of using gravity to generate electricity, it cannot continuously provide electricity. Therefore, further research and development in methods and devices using gravity to provide continuous generation of electricity are necessary.
To solve the above problems, it is an objective of the present invention to provide a gravity-driven electricity generating device which utilizes a change in the centers of gravity of two power units to form two powers for repeatedly pivoting a pressing board of a pivotal module, thereby enabling a generator to generate electricity.
It is another objective of the present invention to provide a power unit for a gravity-driven electricity generating device. The power unit can swing through a change in the center of gravity, repeatedly pivoting a pressing board of a pivotal module, thereby enabling rotation of a generator for generating electricity.
It is a further objective of the present invention to provide a method for generating electricity using gravity, which utilizes two power units to repeatedly form two powers for repeatedly pivoting a pivotal module, enabling rotation of a generator for generating electricity.

A gravity-driven electricity generating device according to the present invention includes a pivotal module, a first power unit, and a second power unit. The pivotal module includes a pressing board pivotable about a pivot. The first power unit includes a first swaying frame. A first external force is provided to pivot the first swaying frame from a first position to a second position to output a first power, thereby moving a first end of the pressing board downward and moving a second end of the pressing board upward to pivot in a first direction. The second power unit includes a first swaying frame. A second external force is provided to pivot the second swaying frame from a first position to a second position to output a second power, thereby moving the first end of the pressing board upward and moving the second end of the pressing board downward to pivot in a second direction. Upward movement of the first end of the pressing board causes the first swaying frame to pivot in the second direction to the first position, and a first external force module provides the first external force. Downward movement of the second end of the pressing board causes the second swaying frame to pivot in the second direction to the first position, and a second external force module provides the second external force.
A method for generating electricity using gravity according to the present invention includes: providing a first external force to pivot a first swaying frame of a first power unit in a first direction, thereby outputting a first power, with the first power actuating a pivotal module to pivot in the first direction; and providing a second external force to pivot a second swaying frame of a second power unit in the first direction, thereby outputting a second power, with the second power actuating the pivotal module to pivot in the second direction. When the pivotal module pivots in the first direction, the pivotal module further enables the second swaying frame to pivot in the second direction, and wherein when the pivotal module pivots in the second direction, the pivotal module further enables the first swaying frame to pivot in the second direction, thereby repeatedly pivoting the pivotal module to enable rotation of a generator for generating electricity.
Thus, with the gravity-driven electricity generating device and the method for generating electricity using gravity according to the present invention, by pivotal movement of the swaying frame of each of the first power unit and the second power unit, the center of gravity of the swaying frame can be shifted, and the gravitational potential energy of the swaying fame is converted into the rotational power for the pivotal movement, thereby driving a respective pivotal module to pivot repeatedly. Furthermore, the power enables the center of gravity of the swaying frame of the other power unit to shift in the second direction, and two external force modules provide an external force to actuate the swaying frames of the two power units to pivot in the first direction. This enables rotation of a generator for generating electricity, thereby providing a green power generation.
In an example, the first swaying frame and the second swaying frame are disposed symmetrically on two sides of the pivotal module. When each of the first swaying frame and the second swaying frame pivots in the first direction, an abutting portion of each of the first swaying frame and the second swaying frame outputs a respective one of the first power and the second power to a respective one of the first and second ends of the pressing board, thereby pivoting the pressing board in a respective one of the first direction and the second direction. Therefore, the first power unit and the second power unit can respectively provide a first power and a second power to the first end and the second end of a pressing board of the pivotal module, causing pivotal movement of the pressing board about a pivot, thereby enabling a generator to rotate continuously for generating electricity.
In an example, each of the first swaying frame and the second swaying frame includes an extension frame. When each of the first swaying frame and the second swaying frame pivots in the second direction, the two extension frames respectively approaching or colliding with the first and second external force modules, thereby providing the first external power and the second external power. Therefore, with the external force module providing an external force, the swaying frame may pivot in the first direction, and the center of gravity of the swaying frame shifts from the first side to the second side of the swaying frame due to unbalance, assuring that the swaying frame can pivot rapidly in the first direction.
In an example, each of the first and second external force modules includes at least one elastic element to provide the first external force or the second external force. Therefore, with returning of the elastic element providing an external force, the swaying frame may pivot in the first direction, and the center of gravity of the swaying frame shifts from the first side to the second side of the swaying frame due to unbalance, assuring that the swaying frame can pivot rapidly in the first direction.
In an example, each of the first and second external force modules and the extension frames includes at least one magnetic member. The magnetic members of the first and second external force modules and the extension frames form a repulsive force to provide the first external force or the second external force. Therefore, with the magnetic elements forming a repulsive force to provide an external force, the swaying frame may pivot in the first direction, and the center of gravity of the swaying frame shifts from the first side to the second side of the swaying frame due to unbalance, assuring that the swaying frame can pivot rapidly in the first direction.
The gravity-driven electricity generating device may further comprise two pre-push modules disposed between the first power unit and the second power unit. Each of the first and second swaying frames includes a sliding track and a sliding member. Each of the two pre-push modules incudes a driving member pivotable about a pivotal center. Each driving member has a push portion on an end thereof and a pressed portion on another end thereof. The two push portions are configured to abut the two sliding members. The two pressed portions are configured to be abutted by abutting portions of the first and second swaying frames. Therefore, the power provided through the pivotal movement of the swaying frame can be partially released stage by stage. Aside from providing abutment of the abutting portion against the pressing board of the pivoting module to enable rotation of a generator for generating electricity, the sliding member enables the swaying frame of the other power unit to pivot more easily in the second direction due to the first-stage movement.
In an example, each of the two sliding members of the first and second swaying frames includes an extension member. Each of the first and second swaying frames includes a sliding track having a linking rod on an end or a bottom thereof. Each linking rod includes at least one auxiliary abutting portion configured to abut a respective one of the pressed portions. Therefore, by abutting the pressed portion with the at least one auxiliary abutting portion, the two push portions at the other end of the driving member can uniformly abut the extension member, assuring first-stage upward movement of the sliding member.
In an example, the pivotal module includes a first pivotal module and a second pivotal module. The pressing board includes a first pivotal portion and a second pivotal portion. Both the first pivotal portion and the second pivotal portion are located on a bottom side of the pressing board. The first pivotal portion and the second pivotal portion are located on two sides of a center of the pivotal module. The first pivotal portion pivots about a pivot of the first pivotal module. The second pivotal portion pivots about a pivot of the second pivotal module. Therefore, during pivotal movement of the pressing board, due to the change of the pivotal portion and the pivot which changes the ratio of the force arms on two sides of the pivot, a larger returning torque can be formed to allow smoother pivotal movement of the pressing board.
The gravity-driven electricity generating device according to the present invention may further include a third power unit and a fourth power unit. The third power unit includes a third swaying frame. A third external force is provided to pivot the third swaying frame from a first position to a second position to output a third power, thereby moving the first end of the pressing board downward and moving the second end of the pressing board upward to pivot in a first direction. The fourth power unit includes a fourth swaying frame. A fourth external force is provided to pivot the fourth swaying frame from a first position to a second position to output a fourth power, thereby moving the first end of the pressing board upward and moving the second end of the pressing board downward to pivot in a second direction. The first swaying frame and the third swaying frame are adjacent to each other and have a first actuating member therebetween. The second swaying frame and the fourth swaying frame are adjacent to each other and have a second actuating member therebetween. Each of the first actuating member and the second actuating member pivots about an axle. During pivotal movement of each of the first, second, third, and fourth power units from the second position to the first position, an extension frame of each of the first, second, third, and fourth swaying frames actuates a respective one of the first and second actuating members to pivot, assisting in pivotal movement from the first position to the second position of an associated one of the first, second, third, and fourth swaying frames of an adjacent one of the first, second, third, and fourth power units. Therefore, the four power units of the gravity-driven electricity generating device according to the present invention operate in sequence to provide interlocking motion, which enables accurate sequential movement of the four power units for rotation of a generator for generating electricity, thereby further enhancing the smoothness and efficacy of rotation of the generator for generating electricity.
The gravity-driven electricity generating device according to the present invention may further include a first frame and a second frame. The first is frame in a form of a substantially rectangular hollow frame. The first frame includes a first end and a second end. The second end of the first frame is coupled with the second end of the pressing board of the pivotal module. The first end of the first frame includes a first guiding board having a first guiding portion and a second guiding portion having an end connected to the first guiding portion. Another end of the second guiding portion forms a free end. The second frame is in a form of a substantially rectangular hollow frame. The second frame includes a first end and a second end. The first end of the second frame is coupled with the first end of the pressing board of the pivotal module. The second end of the second frame includes a second guiding board having a first guiding portion and a second guiding portion having an end connected to the first guiding portion. Another end of the second guiding portion forms a free end. The first frame and the second frame are arranged in an X-shaped arrangement. Therefore, when the abutting portion of the swaying frame comes in contact with the first guiding board or the second guiding board, the engaging portion of the first frame or the second frame can form a pivot-like structure causing slight downward bending deformation at the other end. Thus, the power can be partially stored, and the stored portion assists in pivotal movement of the swaying frame in the second direction.
A power unit for a gravity-driven electricity generating device according to the present invention includes a base and a swaying frame. The base includes a fulcrum. The swaying frame includes a pivotal portion to abut and pivot about the fulcrum defining a pivotal center. The swaying frame includes a center of gravity. The swaying frame defines a first side and a second side on two sides of the pivotal center. The center of gravity of the swaying frame forms a first position on the first side. When the swaying frame pivots in the first direction, the center of gravity moves from the first side to a second side of the swaying frame to form a second position and to output a power.
Therefore, in the power unit of the gravity-driven electricity generating device according to the present invention, by the pivotal movement of the swaying frame, the gravitational potential energy can be converted into rotational energy to output a power for pivoting a swinging module, thereby enabling rotation of a generator for generating electricity.
The power unit for the gravity-driven electricity generating device according to the present invention may further include an external force module. The external force module includes at least one elastic element or at least one magnetic member, such that the swaying frame collides with or approaches the external force module, thereby providing an external force to pivot the swaying frame in the first direction. Therefore, the at least one elastic element or the at least one magnetic member can provide an external force to enable pivotal movement of the swaying frame in the first direction.
In an example, the swaying frame includes an extension frame configured to collide with or approach the external force module, thereby providing the external force. Therefore, an external force can be provided through collision with or approaching the external force module, thereby providing an external force to enable pivotal movement of the swaying frame in the first direction.
In an example, the swaying frame includes a balancing weight fixed to the extension frame. Therefore, by changing the position of the balancing weight, the center of gravity of the swaying frame can be rapidly shifted to the second side, such that the swaying frame can pivot rapidly and output a larger power.
In an example, the swaying frame includes a sliding track and a sliding member. The sliding member is movable in a preset range on the sliding track. When the swaying frame pivots in the first direction, the sliding member displaces to shift the center of gravity of the swaying frame from the first side to the second side. Therefore, by displacement of the sliding member, the center of gravity of the swaying frame can be rapidly shifted to the second side, such that the swaying frame can pivot rapidly and output a larger power.
In an example, the sliding track extends outward from the second side of the swaying frame. An abutting portion is formed on at least one of an edge and a bottom side of the sliding track which extends outward. Therefore, the frictional force between the abutting portion and the pressing board can be reduced to reduce loss of energy.
In an example, the sliding track includes a first sliding track and a second sliding track. The first sliding track is located on the second side of the swaying frame. The second sliding track is located on the first side of the swaying frame. The sliding member includes a first sliding member and a second sliding member. The first sliding member is slidable on the first sliding track. The second sliding member is slidable on the second sliding track. Therefore, through displacement of the two sliding members, the center of gravity of the swaying frame can rapidly shift between the first side and the second side, such that the swaying frame can achieve effects of rapid pivoting, output of a larger power, and returning movement.
in an example, the first sliding member is provided with a returning element. Therefore, the returning element enables easy returning of the first sliding member.
The power unit for the gravity-driven electricity generating device according to the present invention may further comprise at least one auxiliary external force module each including a rectilinear track fixed on the base. The rectilinear track provides reciprocal sliding movement for a linear bearing. Two ends of an elastic element are fixed on the linear bearing and the second sliding member, respectively. Therefore, the auxiliary external force module can provide a larger auxiliary external force, such that the swaying frame can more easily pivot in the first direction or the second direction.
In an example, the base includes a first fulcrum and a second fulcrum. The swaying frame includes a first pivotal portion and a second pivotal portion. When the center of gravity of the swaying frame is located on the first side, the swaying frame pivots by the first pivotal portion and the first fulcrum. When the center of gravity of the swaying frame is located on the second side, the swaying frame pivots by the second pivotal portion and the second fulcrum. Therefore, during pivotal movement of the swaying frame, due to the change of the pivotal portion and the pivot which changes the ratio of the force arms two sides of the pivot, a larger torque can be formed to allow smoother pivotal movement of the swaying frame.
In an example, the swaying frame includes a body and a frame having a first side coupled with the body by an engaging member. A second side of the frame abuts the body. The pivotal portion is located on a bottom end of the body. The frame is located on top of the body. Therefore, the swaying frame can pivot easily.
The method for generating electricity using gravity according to the present invention may further includes providing an auxiliary external force to assist in returning of a sliding member, thereby assisting in pivotal movement of the first swaying frame and the second swaying frame in a respective one of the first and second directions. Therefore, the auxiliary external force enables the swaying frame to pivot more easily in the first direction or the second direction.
The method for generating electricity using gravity according to the present invention may further provide an energy-storing mechanism. The first power provided by the first power unit and the second power provided by the second power unit are partially stored in an energy storage module, and wherein the power partially stored in the energy storage module is used to aid pivotal movement of the first swaying frame and the second swaying frame in the second direction. Therefore, the stored partial power enables the first swaying frame and the second swaying frame to pivot more easily in the second direction.
The present invention will become more fully understood from the detailed description given hereinafter and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:

Preferably, the center of gravity of the swaying frame 2 (2a) is located adjacent to a center of the swaying frame 2 (2a), such that the swaying frame 2 (2a) is in a nearly balanced state.

Namely, the swaying frame 2 (2a) can pivot in the first direction by simply pushing the swaying frame 2 (2a) in the first direction, and the sliding member 23 can move away from the fulcrum 11 along Y axis.

Furthermore, in this embodiment, two ends of the returning element 231 are fixed on the extension frame 24, and the returning element 231 extends around the first sliding member 23a.

In the gravity-driven electricity generating device and the method for generating electricity using gravity according to the present invention, the external force module U does work on the power unit F to cause rotational movement of the power unit F, in which the work done by the external force is converted into rotational energy. Furthermore, the power units F can do work on each other to transmit kinetic energy, and the power units F can do work on the pivotal module E to rotate the pivotal module E and thereby to drive a generator. The above processes of continuous conversion between work and energy fulfills the work-energy theorem. Furthermore, during the pivotal movements of the power units F and the pivotal module E, the rotational energy can be converted into gravitational potential energy, elastic potential energy, and magnetic potential energy, which can be stored in elements, such as a plurality of balancing weights W, elastic elements, returning elements, frames, and magnetic elements. The stored potential energy can be used to provide energy for returning and continuous rotation of the power units F and the pivotal module E. Therefore, the present invention fulfils the work-energy theorem and the law of conservation of energy.
In view of the foregoing, with the gravity-driven electricity generating device and the method for generating electricity using gravity according to the present invention, by pivotal movement of the swaying frame of each of the first power unit and the second power unit, the center of gravity of the swaying frame can be shifted, and the gravitational potential energy of the swaying fame is converted into the rotational power for the pivotal movement, thereby driving a respective pivotal module to pivot repeatedly. Furthermore, the power enables the center of gravity of the swaying frame of the other power unit to shift in the second direction, and two external force modules provide an external force to actuate the swaying frames of the two power units to pivot in the first direction. The auxiliary external force module can provide an auxiliary external force to enable the swaying frame to pivot more easily. The energy storage module can store a portion of the first power and a portion of the second power, which provides assistance in returning of the swaying frame, such that the operation of the gravity-driven electricity generating device can be more smooth, which enables rotation of a generator for generating electricity, thereby providing a green power generation.
