[0001] The present invention relates to the technical field of power generation equipment, and particularly to a chain-climbing gravity ball power generation system. Background Art

[0002] The principle of gravity energy storage technology is to store energy by utilizing gravitational potential energy and convert the stored potential energy into electric energy when needed. This technology mainly uses the potential energy caused by gravity to store energy, and realizes the storage and release of potential energy by raising or lowering liquid or solid heavy objects in scenarios with natural or artificial height differences. During the power generation process, a conveying device is required to lower the heavy object block from a high place to a low place, so that the heavy object block continuously and stably does work under the action of gravity and is converted into continuous torque to drive the power generation equipment. However, the existing lifting devices and conveying devices operate independently, and cannot achieve cyclic continuous operation, which leads to the need to use a multi-channel gravity energy storage method. The multi-channel gravity energy storage has a large floor area and poor continuity, and there are certain limitations. Summary of the Invention

The gravity transmission chain unit includes a sprocket, a chain, and multiple groups of ball support frames fixedly arranged on the chain. The ball support frames receive the gravity balls and drive the chain to rotate cyclically under the gravity of the gravity balls. The chain drives the sprocket to rotate, and the generator is power-connected to the sprocket. The water circulation ball delivery unit includes a water tank, a return pipe, several groups of ball recovery modules, and a ball return pipe that are sequentially connected to form a circulating water path. The gravity balls on the ball support frames fall into the ball recovery modules, and the gravity balls are recovered into the water tank through the ball return pipe. A ball transfer module is arranged on the water tank for transferring the gravity balls in the ball return pipe to the ball support frames.

[0005] As a further improvement of the above technical solution: The chain is of a Z-shaped structure, including an upper horizontal section, an inclined section, and a lower horizontal section. The ball recovery modules are correspondingly arranged below the lower horizontal section, and the ball transfer modules are correspondingly arranged above the upper horizontal section.

[0006] A ball guiding groove for receiving the gravity balls and a ball pushing device for pushing the gravity balls from the ball guiding groove into the ball recovery module are further provided between the lower horizontal section and the ball recovery module.

[0007] A first connecting pipe and a second connecting pipe are also connected in communication between the water return pipe and the ball return pipe. A high-pressure water pump is arranged in the first connecting pipe, and a stop valve is arranged in the second connecting pipe.

[0008] The ball recovery module includes a recovery pipe, a first gate valve device arranged on the water flow input side of the recovery pipe, and a second gate valve device arranged on the water flow output side of the recovery pipe. A ball inlet for the gravity balls to fall into is formed on the recovery pipe. A movable cover plate is rotatably arranged on the recovery pipe, and a first air cylinder for driving the movable cover plate to rotate is further arranged on the recovery pipe to open or close the ball inlet.

[0011] A vertical pipe section is formed by extending the output end of the ball return pipe in the water tank. The ball transfer module includes a ball supporting groove, a ball outlet pipe, and a rotating wheel device. The input end of the ball supporting groove is connected to the output end of the vertical pipe section. The output end of the ball supporting groove is connected to the input end of the ball outlet pipe. The output end of the ball outlet pipe is arranged opposite to the ball supporting frame.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments

[0026] As Figures 1 to 9As shown in the figure, the chain climbing gravity ball power generation system of this embodiment includes a gravity transmission chain unit 100, a water circulation ball feeding unit 200, gravity balls 300, and a generator 400. The gravity transmission chain unit 100 includes a sprocket 1, a chain 2, and multiple groups of ball carriers 3 fixedly arranged on the chain 2. The ball carriers 3 carry the gravity balls 300. Under the action of the gravity of the gravity balls 300, the chain 2 is driven to rotate in a cycle. The chain 2 drives the sprocket 1 to rotate, and the generator 400 is power-connected to the sprocket 1; the water circulation ball feeding unit 200 includes a water tank 4, a return pipe 5, several groups of ball recovery modules 6, and a ball return pipe 7 that are connected in sequence to form a circulating water path. The gravity balls 300 on the ball carriers 3 fall into the ball recovery modules 6, and the gravity balls 300 are recovered into the water tank 4 through the ball return pipe 7. A ball transfer module 8 for transferring the gravity balls 300 in the ball return pipe 7 to the ball carriers 3 is arranged on the water tank 4. This chain climbing gravity ball power generation system includes gravity balls 300, a gravity transmission chain unit 100 for doing work by lowering the gravity balls 300 from a high place to a low place, a water circulation ball feeding unit 200 for storing energy by lifting the gravity balls 300 from a low place to a high place, and a generator 400. The ball carriers 3 on the chain 2 carry the gravity balls 300. Under the action of the gravity of the gravity balls 300, the chain 2 is driven to rotate in a cycle, thereby driving the sprocket 1 to rotate, and further driving the generator 400 to convert kinetic energy into electrical energy. After the gravity balls 300 drop to the low position, they fall into the ball recovery modules 6. Under the action of buoyancy and water flow pushing, the gravity balls 300 are lifted to the water tank 4 located at a high place through the ball return pipe 7. The ball transfer module 8 on the water tank 4 transfers the gravity balls 300 to the ball carriers 3. Through the cooperation of the gravity transmission chain unit 100 and the water circulation ball feeding unit 200, the gravity balls 300 can move back and forth between these two systems, realizing single-channel cyclic continuous operation. Moreover, the gravity balls 300 are lifted and stored energy under the action of buoyancy and water flow pushing, which can improve the energy conversion efficiency while reducing energy consumption, making this chain climbing gravity ball power generation system have the advantages of simple overall structure, few equipment required for cooperative installation, low cost, and small floor area, and the overall work is smooth, with strong continuous operation ability, and can effectively improve the energy conversion efficiency.

[0027] It should be noted that in this embodiment, the number of groups of the ball recovery modules 6 is set to five groups. In other embodiments, the number of groups of the ball recovery modules 6 can also be adaptively increased or decreased according to the on-site implementation conditions.

[0028] As Figure 2 As shown in the figure, preferably, the chain 2 is of a Z-shaped structure, including an upper horizontal section 201, an inclined section 202, and a lower horizontal section 203. The ball recovery modules 6 are correspondingly arranged below the lower horizontal section 203, and the ball transfer module 8 is correspondingly arranged above the upper horizontal section 201.

[0029] As Figure 4As shown, preferably, a ball guiding groove 9 for receiving the gravity balls 300 and a ball pushing device 10 for pushing the gravity balls 300 from the ball guiding groove 9 into the ball recovery module 6 are further provided between the lower horizontal section 203 and the ball recovery module 6. In this embodiment, a first ball guiding elbow is provided at the input end of the ball guiding groove 9, the ball pushing device 10 is provided on one side of the ball guiding groove 9, and a second ball guiding elbow is provided on the other side. The ball pushing device 10 and the second ball guiding elbow are arranged in one-to-one correspondence with the ball recovery module 6. When the chain 2 rotates to the turning position, the gravity balls 300 on the ball supporting frame 3 fall into the ball guiding groove 9 along the first ball guiding elbow. The ball pushing device 10 extends to push the gravity balls 300 from the ball guiding groove 9 towards the second ball guiding elbow, and the gravity balls 300 fall into the ball recovery module 6 along the second ball guiding elbow.

[0030] As Figure 5 shown, preferably, a first connecting pipe 11 and a second connecting pipe 12 are also connected in communication between the water return pipe 5 and the ball return pipe 7. A high-pressure water pump 13 is arranged in the first connecting pipe 11, and a stop valve 14 is arranged in the second connecting pipe 12. In this embodiment, when the system starts for the first time, the stop valve 14 in the second connecting pipe 12 is in a closed state. It is necessary to electrically drive the high-pressure water pump 13 to work so that the water in the water return pipe 5, the first connecting pipe 11 and the ball return pipe 7 circulates. At this time, the high-pressure water pump 13 can be shut down, and at the same time, the stop valve 14 is controlled to open, and the water tank 4, the water return pipe 5, the second connecting pipe 12 and the ball return pipe 7 are connected in sequence to form a circulating water path for transporting the gravity balls 300. After the gravity balls 300 enter the ball return pipe 7 from the ball recovery module 6, the gravity balls 300 will float and rise along the ball return pipe 7 under the action of the water medium, and the water flow in the water tank 4, the water return pipe 5 and the ball return pipe 7 can push the gravity balls 300 to rise by taking advantage of the force.

[0031] It should be noted that in this embodiment, a first ball intercepting grid for intercepting the gravity balls 300 to prevent the gravity balls 300 from flowing back into the second connecting pipe 12 is provided at one end of the ball return pipe 7 close to the second connecting pipe 12.

[0032] As Figure 6As shown, preferably, the ball recovery module 6 includes a recovery pipe 601, a first gate valve device 602 disposed on the water flow input side of the recovery pipe 601, and a second gate valve device 603 disposed on the water flow output side of the recovery pipe 601. An inlet 604 for the gravity ball 300 to fall into is formed on the recovery pipe 601. A movable cover plate 605 is rotatably arranged on the recovery pipe 601, and a first cylinder 606 for driving the movable cover plate 605 to rotate is further arranged on the recovery pipe 601 to open or close the inlet 604. In this embodiment, when the ball recovery module 6 is in a state of waiting for the gravity ball 300 to fall, the first gate valve device 602 and the second gate valve device 603 remain closed, and both ends of the recovery pipe 601 are in a truncated state. When the gravity ball 300 falls into the recovery pipe 601, the first cylinder 606 acts to close the movable cover plate 605 and close the inlet 604. The first gate valve device 602 and the second gate valve device 603 are opened. Under the action of buoyancy and water flow, the gravity ball 300 enters the ball return pipe 7. Since multiple in-place detection devices are arranged in the ball return pipe 7, when the in-place detection device detects the position signal of the gravity ball 300, it sends a signal to the PLC control system, thereby judging and controlling the first gate valve device 602 and the second gate valve device 603 to close and waiting for the next gravity ball 300 to fall.

[0033] It should be noted that, in this embodiment, a second ball intercepting grid for intercepting the gravity ball 300 to prevent it from flowing back into the return pipe 5 is arranged at one end of the recovery pipe 601 close to the water flow input side.

[0034] Preferably, the first gate valve device 602 includes a first gate plate 6021 inserted into the recovery pipe 601 and a second cylinder 6022 for driving the first gate plate 6021 to reciprocate to control the recovery pipe 601 to be in a connected or truncated state. The second gate valve device 603 includes a second gate plate 6031 inserted into the recovery pipe 601 and a third cylinder 6032 for driving the second gate plate 6031 to reciprocate to control the recovery pipe 601 to be in a connected or truncated state. In this embodiment, both the first gate valve device 602 and the second gate valve device 603 adopt the form of cylinder drive, which has the advantages of simple structure, convenient and fast installation and disassembly, long service life, and low cost. In other embodiments, the first gate valve device 602 and the second gate valve device 603 can also adopt components with reciprocating movement functions such as a gear-rack mechanism, a lead screw mechanism, an oil cylinder, and an electric cylinder, which are not limited to this embodiment.

[0035] Preferably, a number of sets of throttle valves 15 are arranged in the return water pipe 5. The throttle valves 15 are arranged in one-to-one correspondence with the ball recovery module 6, and the throttle valves 15 are located on the downstream side of the input end of the ball recovery module 6. In this embodiment, the throttle valves 15 are arranged in the return water pipe 5 and located on the downstream side of the input end of the ball recovery module 6. The flow rate ratio of different ball recovery modules 6 can be controlled by adjusting the opening degree of the throttle valves 15 to achieve dynamic distribution. For example, when the second set of ball recovery modules 6 along the water flow direction needs water flow input, the throttle valve 15 corresponding to the first set of ball recovery modules 6 is opened, and at the same time, the throttle valve 15 corresponding to the second set of ball recovery modules 6 is closed, so that part of the water flow can be input into the second set of ball recovery modules 6 to ensure the flexibility and safety of the system operation.

[0036] As Figures 7 to 9 shown, preferably, a vertical pipe section 701 is formed by extending the output end of the ball return pipe 7 in the water tank 4. The ball transfer module 8 includes a ball support groove 801, a ball outlet pipe 802 and a rotating wheel device 803. The input end of the ball support groove 801 is connected to the output end of the vertical pipe section 701, the output end of the ball support groove 801 is connected to the input end of the ball outlet pipe 802, and the output end of the ball outlet pipe 802 is arranged opposite to the ball support frame 3. The rotating wheel device 803 rotates to transfer the gravity ball 300 from the ball support groove 801 to the ball outlet pipe 802. In this embodiment, when the gravity ball 300 is lifted along the ball return pipe 7 into the water tank 4, the gravity ball 300 enters the input end of the ball support groove 801, and the rotating wheel device 803 rotates to transfer the gravity ball 300 along the ball support groove 801 into the ball outlet pipe 802. The gravity ball 300 falls back onto the ball support frame 3 along the ball outlet pipe 802 to form a cyclic operation for power generation.

[0037] Preferably, the rotating wheel device 803 includes a rotating wheel 8031 and a driving motor 8032 for driving the rotating wheel 8031 to rotate. A number of sets of grids 8033 are arranged on the rotating wheel 8031, and a ball placement cavity 8034 capable of accommodating one gravity ball 300 is formed at intervals between any two adjacent grids 8033.

[0038] Preferably, a number of sets of ball blocking gate plates 8021 are inserted into the ball outlet pipe 802, and a fourth air cylinder 8022 for driving the ball blocking gate plates 8021 to reciprocate is further arranged on the ball outlet pipe 802 to control the output order of the gravity balls 300 in the ball outlet pipe 802. In this embodiment, four sets of ball blocking gate plates 8021 and a fourth air cylinder 8022 are arranged on the ball outlet pipe 802. After the gravity balls 300 enter the ball outlet pipe 802, the four sets of ball blocking gate plates 8021 distribute the balls in an orderly manner. The output rhythm of the gravity balls 300 is adapted to the running speed of the chain 2, so that the gravity balls 300 accurately fall into the ball support frame 3.

[0039] In summary, in practical applications, when the system starts up initially, the stop valve 14 in the second connecting pipe 12 is in the closed state. It is necessary to drive the high-pressure water pump 13 electrically to make the water in the return pipe 5, the first connecting pipe 11 and the ball return pipe 7 circulate. At this time, the high-pressure water pump 13 can be shut down, and at the same time, the stop valve 14 is controlled to open, connecting the water tank 4, the return pipe 5, the second connecting pipe 12 and the ball return pipe 7 in sequence to form a circulating water path for the gravity ball 300 to operate. After the gravity ball 300 enters the ball return pipe 7 from the ball recovery module 6, under the action of the water medium, the gravity ball 300 will float and rise along the ball return pipe 7. Moreover, the water flow in the water tank 4, the return pipe 5 and the ball return pipe 7 can help to push the gravity ball 300 to rise. When the gravity ball 300 rises along the ball return pipe 7 into the water tank 4, the gravity ball 300 enters the input end of the ball support groove 801, and the rotating wheel device 803 rotates to transfer the gravity ball 300 along the ball support groove 801 into the ball outlet pipe 802. After the gravity ball 300 enters the ball outlet pipe 802, the four groups of ball blocking gate plates 8021 distribute the balls in an orderly manner. The output beat of the gravity ball 300 is adapted to the running speed of the chain 2, so that the gravity ball 300 accurately falls into the ball support 3. Under the gravity action of the gravity ball 300, the chain 2 rotates in a cycle. The chain 2 drives the sprocket 1 to rotate, and the generator 400 is power-connected to the sprocket 1 to generate electricity. When the chain 2 runs to the turning position, the gravity ball 300 on the ball support 3 falls into the guide ball groove 9 along the first guide ball elbow. The ball pushing device 10 extends to push the gravity ball 300 from the guide ball groove 9 to the second guide ball elbow, and the gravity ball 300 falls into the ball recovery module 6 along the second guide ball elbow. When the ball recovery module 6 is waiting for the gravity ball 300 to fall, the first gate valve device 602 and the second gate valve device 603 remain closed, and both ends of the recovery pipe 601 are in a truncated state. When the gravity ball 300 falls into the recovery pipe 601, the first cylinder 606 acts to cover the movable cover plate 605 and close the ball inlet 604. The first gate valve device 602 and the second gate valve device 603 open, and at the same time, the corresponding throttle valve 15 closes, so that part of the water flow is input into the corresponding recovery pipe 601. Under the action of buoyancy and water flow push, the gravity ball 300 enters the ball return pipe 7. Since there are multiple sets of in-place detection devices in the ball return pipe 7, when the in-place detection device detects the position signal of the gravity ball 300, it sends a signal to the PLC control system, thereby judging and controlling the first gate valve device 602 and the second gate valve device 603 to close, and the throttle valve 15 to open, waiting for the next gravity ball 300 to fall. The above is a complete working process of the chain climbing type gravity ball power generation system of the present invention.

[0040] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art of this technology, the improvements and transformations obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
