Description

Technical Field

[0001] The present invention relates to the field of power storage systems, and particularly to a gravity power generation device. Background Art

[0002] During the process of gravity energy storage power generation, gravitational potential energy is proportional to the height and the mass of the lifted object. Usually, the power generation time is extended by increasing the height of the heavy object rather than increasing its mass. For example, gravity power generation is achieved through vertical spaces (such as high towers, mountains, and mines) because there is a large amount of available space away from urban areas. However, in densely built areas such as cities, the available vertical height for gravity power generation is less, and it is difficult to apply increasing the lifting height to meet the requirements of gravity energy storage. Therefore, the form of increasing the weight of the lifted object can be adopted to improve energy storage.

[0003] However, when increasing the weight of the lifted object to improve the gravity energy storage capacity in a low space, a greater lifting weight of a single gravity energy storage power generation device means a higher power requirement for the lifting equipment and higher requirements for the winch. At the same time, a larger counterweight mass brings a stronger inertial force for the lifting and lowering actions, a stronger impact on the overall mechanical structure, and more difficult safety guarantee. In addition, only increasing the gravitational potential energy and keeping the falling height unchanged, more energy is released per unit time, resulting in higher power requirements for the generator, increased equipment costs, reduced stability, and a short power generation cycle. Summary of the Invention

[0004] The purpose of the present invention is to provide a gravity power generation device to solve the above problems. A plurality of gravity energy storage units are arranged horizontally outside the shaft tube and can operate independently. They can be arranged orderly in a relatively low space. Through step-by-step energy storage and release, high-power gravity energy storage power generation can be satisfied, with low requirements for site space. The multi-stage gravity energy storage mechanism adopts a modular design, which is convenient for installation, disassembly, and combination, and can flexibly adjust the equipment scale and layout according to the actual space situation and power generation requirements, making it convenient for urban applications. Details are described below.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A gravity power generation device provided by the present invention includes a top frame, a shaft tube, and a sling. The shaft tube is horizontally rotatably arranged below the top frame. A plurality of horizontally arranged mounting rings are coaxially sleeved outside the shaft tube, and a rotating frame for supporting the rotation of the mounting ring is fixed to the bottom side of the top frame. A plurality of movable frames forming an expandable drum structure are arranged around the outside of the mounting ring. The movable frames are used to rotate and wind the sling to pull the counterweight up for energy storage. A restraint tube for locking the rotation action of the movable frame and the shaft tube is horizontally slidably arranged inside the shaft tube.

[0007] The rotating frame includes an inner arc plate and an outer arc plate respectively arranged on the inner and outer sides of the mounting ring, the inner arc plates are in two groups and are symmetrically distributed, connecting plates are fixed on the outer sides of the two groups of inner arc plates, a radial rod that passes through the mounting ring is fixed between the connecting plate and the outer arc plate, a radial spring that keeps the outer arc plate stretched outward is sleeved on the outer side of the radial rod, a constraint groove is formed between the two groups of inner arc plates, a tenon piece that is engaged with the constraint groove is vertically slidably arranged on the outer side of the rotating frame, a constraint plate that extends into the constraint groove is arranged at the end of the constraint tube, the constraint plate is used to push the tenon piece out of the constraint groove to realize the release of the counterweight of the sling, and an inner tube spring that is pressed against the end of the constraint tube away from the constraint plate is arranged inside the shaft tube.

[0008] The above-mentioned gravity power generation device is used, and the rotating frame, the mounting ring and the movable frame cooperate to form a gravity energy storage mechanism for pulling and winding up the slings to pull up the counterweight. When in use, the following steps are included:

[0009] S1. Gradually release the gravity energy storage mechanism to realize power generation. At this time, the restraint cylinder is at the right position of the rightmost group of rotating frames. The movement process of the restraint cylinder from right to left is set as a power generation process in which multiple slings are released one by one, which specifically includes the following operations:

[0010] S101, keep the reduction motor powered off, the winch gradually releases the pull rope, and the inner tube spring pushes the constraint cylinder to gradually move horizontally from right to left as a whole. The multiple constraint plates on the constraint cylinder move horizontally close to the right side of the rotating frame. When the constraint plate moves into the constraint groove between the adjacent inner arc plates, the constraint plate pushes the tenon inserted into the constraint groove upward and disengages it. At this time, the rotating frame cooperates with the tenon to release the rotation locking state of the group of gravity energy storage mechanism. The counterweight pulls the sling downward, and the sling pulls the movable frame and the mounting ring. The constraint plate inserted into the constraint groove is used to keep the group of gravity energy storage mechanism and the shaft tube rotating synchronously, and the output gear outside the shaft tube is used to drive the generator to rotate, thereby realizing the gravity release power generation action of the first-stage gravity energy storage mechanism.

[0011] S102. When the counterweight of the first-stage gravity energy storage mechanism on the far right moves down to the ground, the sling is released and in a loose state. At this time, the winding and tightening state of the multiple groups of outer arc plates on the outer circumference of the mounting ring is released. At this time, the outer arc plates of the first-stage gravity energy storage mechanism expand outward under the action of radial springs, and at the same time drive the inner arc plates to move outward, so as to synchronously move the constraint grooves of adjacent inner arc plates outward, and then synchronously remove the multiple groups of constraint plates from the constraint grooves, that is, the multiple inner arc plates of the first-stage gravity energy storage mechanism are synchronously expanded and stretched out, thereby removing the lateral movement obstruction of the pad to the constraint plate. At this time, the constraint tube is pushed toward the direction of the second-stage gravity energy storage mechanism on the left under the pushing action of the inner tube spring, so as to realize the sequential release of the multiple-stage gravity energy storage mechanisms, thereby driving the shaft tube to rotate one by one to extend the power generation cycle.

[0012] S2. When the counterweights of the multi-stage gravity energy storage mechanism need to be rotated and raised to the energy storage height one by one, the restraint cylinder is at the left position of the leftmost group of rotating frames, and the movement process of the restraint cylinder from left to right is set as the energy storage process of multiple slings successively winding up the counterweights, which specifically includes the following operations:

[0013] S201, keep the reduction motor energized, and use the winch to reel in and pull the pull rope, and pull the constraint cylinder from left to right and move it horizontally, so as to pull the constraint plate into the force-bearing groove close to the one-way block. At this time, the constraint plate continues to move horizontally, thereby pushing the one-way block to drive the movable plate to move horizontally in the direction close to the tenon part, and use the fourth inclined surface of the movable plate to push the tenon part upward, and the constraint plate pushes the one-way block to the right to support the movable plate to push the tenon part upward out of the constraint groove, thereby releasing the locking state of the tenon part on the constraint groove. At this time, the reduction motor is used to drive the shaft tube to rotate, and the shaft tube drives the one-way block and the pad through the constraint plate extending out of the guide groove to realize the rotation action of the leftmost group of gravity energy storage mechanisms, so as to realize the rotation and lifting energy storage process of a group of slings on the counterweight;

[0014] S202. After the leftmost group of gravity energy storage mechanisms has completed energy storage, the winch is used to pull the constraint cylinder to move to the right, and the constraint plate is blocked by the one-way block. At this time, the support arm supports the constraint plate to gather and retract toward the axis of the thin rod, and at the same time, the synchronous ring slides toward the direction close to the baffle plate to compress the retaining spring, thereby ensuring that multiple groups of constraint plates can be rotated and retracted to pass through the internal channels of multiple groups of inner arc plates in a tight state. When the tightening effect of the constraint plate on the one-way block disappears, the reset block is pushed by the reset spring to reset the movable plate, thereby staggering the movable plate and the latch. At this time, the latch moves down again and is latched into the inner constraint groove of the movable frame that completes the winding and energy storage process, completing the first-level energy storage locking process;

[0015] S203, after the constraint cylinder pulls multiple constraint plates out from the inner side of the active frame that has stored energy, it continues to pull and move horizontally to the right through the pull rope, keeping the spring pushing the synchronization ring to use the support arm to support the constraint plate to an upright state again, and then the constraint plate is inserted into the outer force groove of the one-way block of the next-level gravity energy storage mechanism to repeat the next-level counterweight winding and lifting energy storage process.

A reset spring is sleeved on the outer side of the reset rod to push the reset block away from the tenon. A lifting hole is penetrated through the end of the movable plate, and a lifting rod is fixed to the side of the one-way block to slide and adapt to the lifting hole.

[0019] Preferably, the constraint cylinder is clearance-matched with the inner wall of the shaft tube, and a thick rod supporting the rotation of the constraint plate is provided at the end of the constraint cylinder, and a thin rod is provided at the end of the thick rod away from the constraint cylinder, and a synchronous ring is sleeved on the outside of the thin rod, and a baffle plate is fixed on the outer end of the thin rod, and a retaining spring is provided on the end face of the baffle plate, which is sleeved on the outside of the thin rod and presses the synchronous ring to the end face of the thick rod, and a support arm is rotatably connected between the outer side of the synchronous ring and the constraint plate.

[0020] Preferably, two groups of side frames supporting the rotation of the end of the shaft tube are fixed on the bottom side of the top frame, and a winch is arranged on the outside of one group of side frames close to the inner tube spring. A pull rope is wound on the outside of the winch, and the pull rope extends into the inner side of the end of the shaft tube and is fixedly connected to the outer end face of the constraint tube.

[0021] Preferably, a reduction motor is fixed to the outside of the side frame at one end of the shaft tube away from the winch, the output end of the reduction motor is connected to the end of the shaft tube through a coupling, and an output gear is coaxially fixed to the end of the shaft tube close to the reduction motor, and the output gear is used to engage the generator input shaft gear.

[0022] Preferably, the rotating frame is a U-shaped frame structure with its opening facing downward, and retaining edges supporting the rotation of the mounting ring are arranged on both sides of the rotating frame, an auxiliary groove accommodating the vertical sliding of the tenon is arranged on the outside of the rotating frame, and suspension bolts fixedly connected to the top frame are arranged at the four corners of the top side of the rotating frame.

The units can be arranged in an orderly manner in a relatively low space. By storing and releasing energy step by step, the units can meet the requirements of high-power gravity energy storage power generation, and have low requirements on site space.

[0026] 2. The traditional large-scale counterweight is divided into multiple slings and connected to the individual counterweights, which greatly reduces the power requirements of the equipment during the lifting process.

[0027] 3. During the energy release process, the inner tube spring pushes the constraint cylinder to move horizontally to the right side of multiple energy storage units step by step, thereby realizing the successive controlled release of multi-stage gravity energy storage. When the counterweight of the first-stage gravity energy storage mechanism descends to complete power generation, under the action of radial springs, return springs and other components, the inner arc plate expands outward, and the constraint cylinder receives the thrust of the inner tube spring and moves horizontally to the next-stage gravity energy storage mechanism to release energy, realizing long-term continuous and stable power supply and reducing human intervention.

[0047] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0048] See Figures 1-16 As shown, the present invention provides a gravity power generation device, including a top frame 1, a shaft tube 2 and a suspension cable 6. The shaft tube 2 is horizontally rotatably arranged below the top frame 1. A plurality of horizontally arranged installation rings 3 are coaxially sleeved outside the shaft tube 2. The inner diameter of the installation ring 3 is larger than the outer diameter of the shaft tube 2. And a rotating frame 4 for supporting the rotation of the installation ring 3 is fixed to the bottom side of the top frame 1. A plurality of movable frames 5 forming an expandable reel structure are arranged around the outside of the installation ring 3. The movable frame 5 is used to rotate and wind up the suspension cable 6 to pull the counterweight upward for energy storage. A constraint cylinder 7 for locking the rotation actions of the movable frame 5 and the shaft tube 2 is horizontally slidably arranged inside the shaft tube 2. The constraint cylinder 7 can lock the rotation state of the shaft tube 2 and the movable frame 5 inside a certain group of rotating frames 4, so as to realize the step-by-step upward energy storage of the counterweight and the step-by-step downward power generation;

[0049] The rotating frame 4 includes an inner arc plate 502 and an outer arc plate 501 respectively arranged on the inner and outer sides of the mounting ring 3. Each group of the inner arc plates 502 of the rotating frame 4 is two groups and are symmetrically distributed. A connecting plate 503 is fixed on the outer sides of the two groups of inner arc plates 502. A radial rod 504 that penetrates the mounting ring 3 is fixed between the connecting plate 503 and the outer arc plate 501. A radial spring 504a is sleeved on the outer side of the radial rod 504 for keeping the outer arc plate 501 tightened outward. When multiple groups of outer arc plates 501 wind up the sling 6 to pull up the counterweight, the multiple groups of outer arc plates 501 can be tightened and gathered inwardly through the sling 6, thereby compressing the radial spring 504a to keep the multiple groups of inner arc plates 502 of the rotating frame 4 in the same tight and gathered state. Similarly, when the counterweight is released to the ground, the sling 6 is loosened. At this time, the radial spring 504a pushes the outer arc plate 501 to drive the radial rod 504 and the inner arc plate 502 to expand outward. A constraint groove 507 is formed between the two groups of inner arc plates 502, and a tenon piece 8 that is engaged with the constraint groove 507 is vertically slidably arranged on the outer side of the rotating frame 4, and the tenon piece 8 is used to maintain the rotation locking state of the rotating frame 4, and a constraint plate 702 that extends into the constraint groove 507 is arranged at the end of the constraint cylinder 7, and the constraint plate 702 is used to push the tenon piece 8 out of the constraint groove 507, thereby releasing the rotation locking state of the rotating frame 4. At this time, the sling 6 releases the counterweight action, and at the same time, the constraint plate 702 locks the shaft tube 2 and the rotating frame 4 to realize synchronous rotation, so as to utilize the rotation of the shaft tube 2 to realize the power generation action, and an inner tube spring 9 is arranged inside the shaft tube 2, which is pressed against the end of the constraint cylinder 7 away from the constraint plate 702.

[0050] As an optional embodiment, the outer wall of the shaft tube 2 is provided with a guide groove 201 for accommodating the extension of the constraint plate 702, the guide groove 201 extends horizontally, a pad 506 is fixed in the constraint groove 507 between the two groups of inner arc plates 502, a first inclined surface 801 is provided on the bottom edge of the tenon member 8 away from the rotating frame 4, and a second inclined surface 702a is provided on the outer end of the constraint plate 702 to fit the first inclined surface 801, and the second inclined surface 702a is used to push the tenon member 8 upward to disengage from the constraint groove 507. With such a configuration, the constraint plate 702 can accurately push the tenon member 8 through the close fit between the inclined surfaces, ensuring that when the counterweight needs to be released for power generation, the tenon member 8 can quickly and accurately disengage from the constraint groove 507;

[0051] A movable plate 505 is horizontally disposed between the backing plate 506 and the connecting plate 503. A one-way block 508 is slidably disposed along the radial direction of the shaft tube 2 at one end of the movable plate 505 away from the tenon member 8. A third inclined surface 508a parallel to the first inclined surface 801 is disposed on the bottom side of the one-way block 508. A stress groove 508b capable of being snap-fitted and adapted to the constraint plate 702 is disposed on the outer side of the one-way block 508. A top groove 503a extending horizontally is vertically penetrated through the middle of the connecting plate 503. A reset rod 503b is horizontally fixed above the top groove 503a. A reset block 505a is fixed to the top side of the movable plate 505 and passes through the top groove 503a and is in horizontal sliding fit with the reset rod 503b. With such a setting, when the constraint cylinder 7 moves horizontally from right to left to realize the successive release of gravitational potential energy, when the sling 6 corresponding to the position of the constraint cylinder 7 is completely released and multiple groups of inner arc plates 502 expand outwards synchronously to a position where they are separated from the constraint plate 702, at this time, when the constraint cylinder 7 drives the constraint plate 702 to move horizontally, since the one-way block 508 is provided with the third inclined surface 508a and the one-way block 508 can slide along the radial direction of the shaft tube 2, it is ensured that when the constraint plate 702 moves horizontally to contact the one-way block 508, the one-way block 508 can be pushed to slide outwards by the constraint plate 702, thereby avoiding the one-way block 508 from hindering the horizontal movement of the constraint cylinder 7 from right to left.

[0052] A fourth inclined surface 505b is disposed on one side of the movable plate 505 away from the one-way block 508. The fourth inclined surface 505b is used to support the tenon member 8 to disengage from the constraint groove 507 upwards. A reset spring 503c that pushes the reset block 505a away from the tenon member 8 is sleeved outside the reset rod 503b. A lifting hole 505c is penetrated through the end of the movable plate 505. A lifting rod 509 that is slidably adapted to the lifting hole 505c is fixed to the side surface of the one-way block 508, improving the smoothness of the radial sliding of the one-way block 508 at the end of the movable plate 505 along the shaft tube 2;

[0053] The constraint cylinder 7 is in clearance with the inner wall of the shaft tube 2. A thick rod 701 is provided at the end of the constraint cylinder 7 to support the rotation of the constraint plate 702. A thin rod 703 is provided at one end of the thick rod 701 away from the constraint cylinder 7. A synchronous ring 705 is sleeved on the outer side of the thin rod 703. A baffle 706 is fixed to the outer end of the thin rod 703. A retaining spring 707 is provided on the end face of the baffle 706, which is sleeved on the outside of the thin rod 703 and presses the synchronous ring 705 to the end face of the thick rod 701. A support arm 704 is rotatably connected between the outer side of the synchronous ring 705 and the constraint plate 702. With this arrangement, when the constraint cylinder 7 drives multiple groups of constraint plates 7 02 When the restraining plate 702 moves horizontally from left to right and performs the step-by-step energy storage action, the restraining plate 702 contacts the force groove 508b of the one-way block 508. At this time, the horizontal movement of the restraining plate 702 can be used to push the one-way block 508 to drive the movable plate 505 to move horizontally, so as to use the fourth inclined surface 505b of the movable plate 505 to push the latching member 8 to move up and out of the restraining groove 507, thereby releasing the rotation locking state of the movable frame 5, so as to facilitate the subsequent rotation of the shaft rod to use the restraining plate 702 to drive the one-way block 508 and the movable frame 5 to rotate as a whole, so as to realize the rotation and lifting process of the movable frame 5 to the sling 6 and the counterweight;

[0054] Two sets of side frames 12 supporting the rotation of the ends of the shaft tube 2 are fixed to the bottom side of the top frame 1. A winch 10 is arranged outside a set of side frames 12 close to the inner tube spring 9. A pull rope 10a is wound and connected to the outer side of the winch 10. The pull rope 10a extends into the inner side of the end of the shaft tube 2 and is fixedly connected to the outer end surface of the constraint cylinder 7. The moving position and speed of the constraint cylinder 7 are controlled by the winch 10 and the pull rope 10a in cooperation with the inner tube spring 9.

[0055] A reduction motor 11 is fixed to the outside of the side frame 12 at one end of the shaft tube 2 away from the winch 10, and the output end of the reduction motor 11 is connected to the end of the shaft tube 2 through a coupling, and an output gear 13 is coaxially fixed to the end of the shaft tube 2 close to the reduction motor 11. The output gear 13 is used to engage the generator input shaft gear. This design is used to transmit the power of the reduction motor 11 to the shaft tube 2, and the shaft tube 2 is used to drive the constraint plate 702 to support the movable frame 5 to rotate and reel in or release the sling 6. At the same time, through the meshing of the output gear 13 and the generator input shaft gear, the gravitational potential energy of the sling 6 when the counterweight is unfolded and descending is converted into electrical energy, thereby achieving a stable power generation function.

[0056] The rotating frame 4 is a U-shaped frame structure with an opening facing downward. On both sides inside the rotating frame 4, there are retaining edges 401 for supporting the rotation of the support mounting ring 3. The design of the U-shaped frame structure and the retaining edges 401 provides stable support for the rotation of the mounting ring 3, ensuring the smoothness of the mounting ring 3 during rotation. Outside the rotating frame 4, there is an auxiliary groove 402 for accommodating the vertical sliding of the clamping tenon 8. The auxiliary groove 402 provides accurate guidance for the vertical sliding of the clamping tenon 8, enabling it to accurately engage or disengage from the restraint groove 507. At the four corners of the top side of the rotating frame 4, there are suspension bolts 403 fixedly connecting to the top frame 1. The suspension bolts 403 ensure the firm connection between the rotating frame 4 and the top frame 1, enhancing the structural stability of the entire device;

[0057] On the mounting ring 3, there are multiple sliding holes 301 corresponding to the movable frame 5. The radial rod 504 penetrates through the sliding holes 301 along the radial direction of the shaft tube 2, and the radial rod 504 has a clearance fit with the sliding holes 301. The diameter of the sliding holes 301 is smaller than the inner diameter of the radial spring 504a. The cooperation design of the sliding holes 301 and the radial rod 504 not only allows the movable frame 5 to have a certain degree of freedom of movement in the radial direction but also, through the action of the radial spring 504a, keeps the position of the movable frame 5 stable, ensuring the smooth winding and releasing of the sling 6.

[0058] On the side of the outer arc plate 501, an arc edge flange extends outward. The top end of the sling 6 is fixed to the outside of one group of outer arc plates 501, and a hook 601 for hanging a counterweight is fixed to the bottom end of the sling 6. The design of the arc edge flange can effectively prevent the sling 6 from slipping during the winding and releasing process, improving the safety of the equipment operation. At the same time, it is convenient for the fixing of the sling 6, ensuring its stability during the working process.

[0059] With the above structure, the rotating frame 4, the mounting ring 3, and the movable frame 5 cooperate to form a gravity energy storage mechanism for pulling and winding the sling 6 to lift the counterweight. When in use, it includes the following steps:

[0060] S1. Gradually release the gravity energy storage mechanism to generate electricity. At this time, the restraint cylinder 7 is at the right position of the rightmost group of rotating frames 4. The process of moving the restraint cylinder 7 from right to left is set as the process of gradually releasing multiple slings 6 to generate electricity, which specifically includes the following operations:

[0061] S101, keep the reduction motor 11 powered off, the winch 10 gradually releases the pull rope 10a, and the inner tube spring 9 pushes the constraint tube 7 to gradually move horizontally from right to left as a whole, and the multiple constraint plates 702 on the constraint tube 7 move horizontally to the right side of the rotating frame 4. When the constraint plate 702 moves into the constraint groove 507 between the adjacent inner arc plates 502, the constraint plate 702 pushes the latching piece 8 inserted into the constraint groove 507 upward and out of it. At this time, the rotating frame 4 cooperates with the latching piece 8 to release the rotation locking state of the group of gravity energy storage mechanism, and the counterweight pulls the sling 6 downward, and the sling 6 pulls the movable frame 5 and the mounting ring 3. The constraint plate 702 inserted into the constraint groove 507 is used to keep the group of gravity energy storage mechanism and the shaft tube 2 rotating synchronously, and the output gear 13 outside the shaft tube 2 is used to drive the generator to rotate, thereby realizing the gravity release power generation action of the first-stage gravity energy storage mechanism;

[0062] S102. When the counterweight of the first-stage gravity energy storage mechanism on the far right moves down to the ground, the sling 6 is released and in a loose state. At this time, the winding and tightening state of the multiple groups of outer arc plates 501 on the outer circumference of the mounting ring 3 by the sling 6 is released. At this time, the outer arc plates 501 of the first-stage gravity energy storage mechanism expand outward under the action of the radial spring 504a, and at the same time drive the inner arc plates 502 to move outward, so as to synchronously move the constraint grooves 507 of the adjacent inner arc plates 502 outward, and then synchronously remove the multiple groups of constraint plates 702 from the constraint grooves 507. That is, the multiple inner arc plates 502 of the first-stage gravity energy storage mechanism are synchronously expanded and stretched out, thereby releasing the lateral movement obstruction of the pad 506 on the constraint plate 702. At this time, the constraint tube 7 is pushed toward the left side of the second-stage gravity energy storage mechanism under the pushing action of the inner tube spring 9, so as to realize the release of the multiple-stage gravity energy storage mechanism in sequence, thereby driving the shaft tube 2 to rotate in sequence to extend the power generation cycle.

[0063] S2. When the counterweights of the multi-stage gravity energy storage mechanism need to be rotated and raised to the energy storage height one by one, the restraint cylinder 7 is at the left position of the leftmost group of rotating frames 4, and the movement process of the restraint cylinder 7 from left to right is set as the energy storage process of the multiple slings 6 successively winding up the counterweights, which specifically includes the following operations:

[0064] S201, keep the reduction motor 11 powered on, and use the winch 10 to reel in the pull rope 10a, pull the constraint cylinder 7 from left to right and move it horizontally, so as to pull the constraint plate 702 into the force groove 508b close to the one-way block 508. At this time, the constraint plate 702 continues to move horizontally, thereby pushing the one-way block 508 to drive the movable plate 505 to move horizontally toward the direction of the latch 8, and use the fourth inclined surface 505b of the movable plate 505 to push the latch 8 upward, so as to restrain The plate 702 pushes the one-way block 508 to the right to support the movable plate 505 to push the tenon 8 upward out of the constraint groove 507, thereby releasing the locking state of the tenon 8 on the constraint groove 507. At this time, the reduction motor 11 is used to drive the shaft tube 2 to rotate. The shaft tube 2 drives the one-way block 508 and the pad 506 to realize the rotation action of the leftmost group of gravity energy storage mechanisms through the constraint plate 702 extending out of the guide groove 201, so as to realize the rotation and lifting energy storage process of a group of slings 6 pairs of counterweights;

[0065] S202, after the leftmost group of gravity energy storage mechanisms have completed energy storage, the winch 10 is used to pull the constraint cylinder 7 to move to the right, and the constraint plate 702 is blocked by the one-way block 508. At this time, the support arm 704 supports the constraint plate 702 to gather and retract toward the axis direction of the thin rod 703, and at the same time, the synchronous ring 705 slides toward the direction close to the baffle plate 706 to compress the retaining spring 707, thereby ensuring that the multiple groups of constraint plates 702 can be rotated and retracted to pass through the internal channels of the multiple groups of inner arc plates 502 in the tight state. When the tightening effect of the constraint plate 702 on the one-way block 508 disappears, the reset block 505a is pushed by the reset spring 503c to reset the movable plate 505, and then the movable plate 505 is staggered with the latch 8. At this time, the latch 8 moves down again and is clamped into the inner constraint groove 507 of the movable frame 5 that completes the winding and energy storage process, completing the first-level energy storage locking process;

[0066] S203, after the constraint cylinder 7 pulls the multiple constraint plates 702 out from the inner side of the movable frame 5 that has stored energy, it continues to pull and move horizontally to the right through the pull rope 10a, and the spring 707 keeps pushing the synchronization ring 705 to use the support arm 704 to support the constraint plate 702 to an upright state again, and then the constraint plate 702 is inserted into the outer force groove 508b of the one-way block 508 of the next-level gravity energy storage mechanism to repeat the next-level counterweight winding and lifting energy storage process.

[0067] The mounting ring 3 of the present invention cooperates with a plurality of movable frames 5 to form a plurality of gravity energy storage units which are arranged transversely outside the shaft tube 2 and can operate independently. The units can be arranged in an orderly manner in a relatively low space, and can meet the requirements of high-power gravity energy storage power generation through step-by-step energy storage and release. The requirements for site space are low. The multi-stage gravity energy storage mechanism adopts a modular design, which is convenient for installation, disassembly and combination. The equipment scale and layout can be flexibly adjusted according to the actual space conditions and power generation needs, and the urban application is convenient.

[0068] The traditional large-scale counterweight is divided into multiple slings 6 to connect the individual counterweights, which greatly reduces the power requirement of the equipment during the lifting process. The inertial impact caused by the lighter counterweight mass when the equipment is started and stopped is significantly reduced, and the impact force on key components such as the shaft tube 2 and the mounting ring 3 is reduced, which effectively improves the stability of the entire system, thereby reducing maintenance costs and extending the service life of the equipment;

[0069] During the energy release process, the inner tube spring 9 pushes the constraint tube 7 to move horizontally step by step to the right side of multiple energy storage units, thereby realizing the successive controlled release of multi-stage gravity energy storage. When the counterweight of the first-stage gravity energy storage mechanism descends to complete power generation, under the action of the radial spring 504a, the return spring 503c and other components, the inner arc plate 502 expands outward, and the constraint tube 7 receives the thrust of the inner tube spring 9 and moves horizontally to the next-stage gravity energy storage mechanism to release energy, thereby realizing long-term continuous and stable power supply and reducing human intervention.

[0070] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
