Technical Field

[0002] Gravity energy storage is an energy storage technology based on the principle of gravitational potential energy. Its core operating mechanism is to store energy by lifting a heavy object to a predetermined height, and to drive a generator to convert energy when needed by lowering the heavy object.

[0003] Currently, mainstream gravity energy storage devices primarily employ either gear chains or wire ropes for power transmission. Gear chain transmission systems suffer from several significant drawbacks: firstly, their complex structure results in low cost-effectiveness under the same traction force; secondly, their insufficient mechanical flexibility limits power transmission efficiency. Wire rope transmission systems, on the other hand, rely heavily on friction for power transmission, leading to two main technical limitations: firstly, the system's load-bearing capacity is significantly restricted; secondly, the need for counterweights and the difficulty in withstanding excessively large unilateral loads severely limit the overall operational load-bearing capacity of the gravity energy storage system.

[0004] Therefore, it is necessary to design a geared chain power transmission mechanism for gravity energy storage to solve the above problems. Utility Model Content

[0034] According to a first aspect of this utility model, a geared chain power transmission mechanism for gravity energy storage is provided, such as... Figures 1 to 8 As shown, the gravity energy storage toothed chain power transmission mechanism is used in a gravity energy storage device. The gravity energy storage toothed chain power transmission mechanism includes a toothed sprocket 1 and a toothed chain 2.

[0035] In the following description, reference will be made to Figures 1 to 8 This section describes the detailed structure of the toothed sprocket 1 and toothed chain 2 of the gravity energy storage toothed power transmission mechanism.

[0036] like Figures 1 to 6 As shown, in this embodiment, the toothed sprocket 1 can be formed into a disc-shaped structure. The outer periphery of the disc-shaped structure is provided with a toothed portion 102 resembling a gear structure, and the center of the toothed portion 102 has a receiving groove 104 resembling a rope. The toothed chain 2 can be understood as a structure combining a chain and a wire rope. The chain body 201 can be understood as resembling a wire rope, and the buckle 202 and engaging member 203 can be understood as a buckle structure resembling a chain, capable of engaging with the toothed portion 102 of the toothed sprocket 1.

[0037] Specifically, the sprocket 1 may include a sprocket body 101 and a plurality of toothed portions 102. The plurality of toothed portions 102 are arranged around the circumferential outer wall of the sprocket body 101, and the plurality of toothed portions 102 can form the teeth of a gear. A roller groove 103 is provided between two adjacent toothed portions 102, and the roller groove 103 is used for engaging and engaging the meshing member 203. The toothed portions 102 have receiving grooves 104, and the receiving grooves 104 are used for engaging the chain body 201.

[0038] The toothed chain 2 may include a chain body 201, fasteners 202, and engaging members 203. Multiple fasteners 202 are spaced apart on the chain body 201, and can be crimped together, where metal fasteners 202 are crimped together at predetermined intervals on the chain body 201. The engaging members 203 are disposed on the fasteners 202, and can be welded together. The chain body 201 is engaged in the receiving groove 104. The chain body 201 can be understood as an approximate steel wire rope structure, which improves the flexibility of the transmission mechanism and increases transmission efficiency. The chain body 201 and the receiving groove 104 can form a structure similar to the friction drive of a steel wire rope and a drive wheel, thereby solving the problems of high cost, insufficient flexibility, and limited power transmission efficiency caused by a single sprocket structure. The fasteners 202 are disposed between two adjacent toothed portions 102, and the engaging members 203 are engaged in the roller groove 103. By engaging the meshing element 203 and the roller groove 103, the toothed chain 2 and the toothed sprocket 1 can form a meshing form similar to that of a gear and a chain, thereby solving the problem of limited load-bearing capacity and difficulty in bearing excessive unilateral load caused by single wire rope transmission.

[0039] This gravity energy storage toothed chain power transmission mechanism, through the cooperation of toothed sprocket 1 and toothed chain 2, combines the two transmission methods of the original wire rope drive and gear chain drive in the gravity energy storage device. By utilizing the cooperation between the chain body 201 and the receiving groove 104, it can form a structure approximating the friction drive of a wire rope and a transmission wheel. The cooperation between toothed chain 2 and toothed sprocket 1 can form a meshing form approximating a gear and chain. This combined component design solves the problems of excessive cost, insufficient flexibility, limited power transmission efficiency, limited load-bearing capacity, and inability to withstand excessive unilateral loads caused by a single sprocket structure. This gravity energy storage toothed chain power transmission mechanism has a compact structure, is easy to assemble and use, and is simple to manufacture. It can achieve stable operation of large-mass, high-efficiency gravity energy storage devices while effectively reducing costs.

[0040] Preferably, such as Figures 1 to 6 As shown in the embodiment, in order to ensure that the chain body 201 and the meshing member 203 have sufficient engagement strength, and at the same time provide mutual support without interfering with each other, the opening direction of the roller groove 103 is perpendicular to the opening direction of the receiving groove 104. That is, the roller groove 103 is opened along the radial direction of the toothed sprocket 1, and the receiving groove 104 is opened along the circumferential direction of the toothed sprocket 1.

[0041] Preferably, such as Figures 1 to 6As shown, in this embodiment, the receiving groove 104 is formed in the middle of the toothed portion 102, and the fastening member 202 has a meshing member 203 at each end in the opening direction of the roller groove 103. To further ensure the stability of the meshing, one fastening member 202 is provided with two meshing members 203, that is, the chain body 201 is fastened in the middle of the toothed portion 102, and a meshing member 203 is provided at each end of the fastening member 202 provided on the chain body 201.

[0042] Preferably, such as Figure 6 As shown in the embodiment, in order to ensure the normal sliding of the meshing member 203, during the operation of the gravity energy storage toothed chain power transmission mechanism, as the toothed chain wheel 1 rotates, the toothed chain 2 locked on the toothed chain wheel 1 will also change position accordingly. In order to avoid the meshing generating large friction force that damages the meshing member 203, the meshing member 203 may include a connecting rod 204 and a sleeve 205. The connecting rod 204 is fixedly set on the buckle member 202, and the fixed setting method can be welding. The sleeve 205 is fitted onto the connecting rod 204. The length of the sleeve 205 is less than the length of the connecting rod 204. The end of the connecting rod 204 is provided with a pin hole 206. When the sleeve 205 is fitted onto the connecting rod 204, the pin hole 206 is located outside the sleeve 205. A pin is inserted into the pin hole 206 to axially fix the sleeve 205 onto the connecting rod 204. Since the inner diameter of the sleeve 205 is greater than the outer diameter of the connecting rod 204, the sleeve 205 can slide relative to the connecting rod 204 to accommodate the rotation of the toothed sprocket 1.

[0043] Preferably, such as Figure 9 As shown, in an embodiment, the gravity energy storage toothed chain power transmission mechanism includes a first toothed sprocket at the top and a second toothed sprocket at the bottom, with the toothed chain 2 surrounding the first and second toothed sprockets to form a loop.

[0044] Preferably, such as Figure 3 As shown, in the embodiment, the receiving groove 104 is formed as a V-shaped groove to facilitate the locking of the chain body 201.

[0045] Preferably, in the embodiment, the toothed chain 2 also has a second structure, the only difference being that the toothed chain 2 includes at least two chain bodies 201 arranged in parallel, while the rest of the structure is the same as in the above embodiment. Specifically, in the second embodiment, the toothed chain 2 includes at least two chain bodies 201 arranged in parallel, each chain body 201 including multiple fasteners 202. The multiple fasteners 202 of one chain body 201 are arranged one-to-one with the multiple fasteners 202 of adjacent chain bodies 201. It can be understood that the number of fasteners 202 and the spacing between them of each chain body 201 are the same as the number of fasteners 202 and the spacing between them of the other chain body 201. The fasteners 202 of one chain body 201 and the corresponding fasteners 202 of the other chain body 201 are connected by a meshing member 203. This meshing member 203 is relatively long, and its two ends can be welded to the two corresponding fasteners 202 respectively. In the second embodiment, the toothed chain 2 can further improve the load-bearing capacity and transportation efficiency of the gravity energy storage device.

[0046] Preferably, such as Figure 7 and Figure 8 As shown, in the second embodiment, corresponding to the two parallel chain bodies 201, the gravity energy storage toothed chain power transmission mechanism includes at least two parallel toothed sprockets 1, which are coaxially arranged, and each toothed sprocket 1 corresponds one-to-one with at least two chain bodies 201. Each toothed sprocket 1 corresponds to one chain body 201 to ensure the stability of the movement.

[0047] like Figure 1 As shown, when the gravity energy storage toothed chain power transmission mechanism is running, the toothed chain wheel 1 rotates under the drive of the central shaft, and a part of the chain body 201 is always located in the receiving groove 104 of the toothed chain wheel 1. The toothed chain 2 moves around the toothed chain wheel 1, and the meshing member 203 meshes with or separates from the roller groove 103.

[0048] This gravity energy storage toothed chain power transmission mechanism, through the cooperation of toothed sprockets and toothed chains, combines the two traditional transmission methods in gravity energy storage devices—wire rope drive and gear chain drive—into a structure similar to the friction drive of a wire rope and a drive wheel. The cooperation between the chain body and the receiving groove creates a structure similar to the meshing of a gear and a chain. This combined component design solves the problems of high cost, insufficient flexibility, limited power transmission efficiency, limited load-bearing capacity, and inability to withstand excessive unilateral loads caused by a single sprocket structure. This gravity energy storage toothed chain power transmission mechanism has a compact structure, is easy to assemble and use, and is simple to manufacture. It can achieve stable operation of large-mass, high-efficiency gravity energy storage devices while effectively reducing costs.

[0049] In addition, such as Figure 9 and Figure 10 As shown, according to a second aspect of the present invention, a gravity energy storage device is provided, the gravity energy storage device including the gear chain power transmission mechanism for gravity energy storage as described above.

[0050] Specifically, to further improve load-bearing capacity, the gravity energy storage device may include multiple sets of gravity energy storage toothed chain power transmission mechanisms, with the toothed sprockets 1 of each set coaxial. These multiple sets of gravity energy storage toothed chain power transmission mechanisms can adopt a single chain body 201 structure or a structure with at least two chain bodies 201 arranged in parallel; there are no restrictions, and users can choose according to their specific needs. The gravity energy storage device may also include a conveyor device 3 that cooperates with the gravity energy storage toothed chain power transmission mechanism. The conveyor device 3 transports the heavy block body 4 to the gravity energy storage toothed chain power transmission mechanism. The conveyor device 3 can be a belt conveyor, commonly used in gravity energy storage devices, and enables the heavy block body 4 to mesh with the gravity energy storage toothed chain power transmission mechanism. To cooperate with the toothed chain 2, the end face of the heavy block body 4 facing the toothed chain 2 may have a meshing hole 401, the size of which is adapted to the size of the meshing member 203.

[0051] During operation, this gravity energy storage device can reduce costs, increase load-bearing capacity, and improve the power generation or energy storage efficiency of gravity energy storage by using a geared chain power transmission mechanism for gravity energy storage.
