Description

Technical Field

[0001] The utility model relates to the technical field of gravity energy storage systems, in particular to a gravity energy storage system support frame and a gravity energy storage system. Background Art

[0002] Gravity energy storage is a method of energy storage and release that converts gravitational potential energy into electrical energy. Specifically, it utilizes height differences in conjunction with electromechanical equipment to raise or lower energy storage blocks, thereby achieving energy storage and conversion. It is a highly sustainable and innovative form of energy storage, offering advantages such as long discharge time, long cycle life, strong environmental adaptability, and high safety. When surplus electricity is generated by renewable energy, the excess energy is used to raise the energy storage blocks for "charging." This increases the height of the weight unit to store gravitational potential energy. When electricity consumption peaks, the system lowers the energy storage blocks, using gravity to "discharge" the blocks, converting gravitational potential energy into electrical energy for release.

However, existing fixed pulley support seats are fixed to the support frame with bolts. These bolts can become loose over time, leading to failure of the fixed pulley support seat, reducing the stability of the gravity energy storage system and posing a threat to worker safety.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] like Figures 1 to 5 As shown, this embodiment provides a gravity energy storage system support frame, which includes a support frame, a casting seat 2 and a fixed pulley 3. The support frame includes a support platform and a frame body arranged on the bottom wall of the support platform. The support rod 1 of the frame body passes through the support platform along the vertical direction Z; the support rod 1 is inserted into the casting seat 2 along the vertical direction Z, and the casting seat 2 is recessed with a receiving hole 23 along the first horizontal direction X. The two side walls of the receiving hole 23 along the second horizontal direction Y are respectively recessed with limiting holes, and the first horizontal direction X and the second horizontal direction Y are perpendicular; the fixed pulley 3 includes a wheel body 31 and a rotating shaft 32 passing through the wheel body 31. The wheel body 31 is located in the receiving hole 23, and the two ends of the rotating shaft 32 are respectively inserted into the two limiting holes. The support frame of the gravity energy storage system is used to support the support platform. The support rod 1 is passed through the support platform, and then the support rod 1 is buried in the casting seat 2 through the casting process. At this time, the casting seat 2 and the support frame are fixed, and the rotating shaft 32 of the fixed pulley 3 is set in two limiting holes, so that the wheel body 31 can only rotate around its axis. Therefore, a steel wire rope is passed around the wheel body 31, one end of the steel wire rope is connected to the energy storage block, and the other end of the steel wire rope is driven to realize the movement of the energy storage block along the vertical direction Z.

[0038] By pre-embedding the support rod 1 into the casting seat 2, there is no need to worry about the problem of failure of the fixing of the casting seat 2 and the support frame after the gravity energy storage system has been working for a long time, which improves the stability of the gravity energy storage system and the safety of the staff.

[0039] Optionally, the casting seat 2 is cast by cement, which can reduce the overall manufacturing cost of the casting seat 2.

[0040] Optionally, the casting seat 2 includes a base 21 and an upper cover 22. The base 21 is arranged on the top wall of the support platform. The support rod 1 is inserted into the base 21 along the vertical direction Z. The top wall of the base 21 is recessed with a first groove 231 along the vertical direction Z. The bottom wall of the upper cover 22 is recessed with a second groove 232 along the vertical direction Z. The upper cover 22 is provided with a through hole 221 along the vertical direction Z. The bottom wall of the upper cover 22 abuts against the top wall of the base 21, and the support rod 1 is inserted into the through hole 221. The first groove 231 and the second groove 232 surround the receiving hole 23. In this embodiment, the casting seat 2 is divided into the base 21 and the upper cover 22. This arrangement can facilitate the installation of the wheel body 31 into the receiving hole 23.

[0041] Optionally, the top wall of the base 21 is provided with two recessed grooves 211 along the vertical direction Z. The two recessed grooves 211 are arranged on either side of the first groove 231 along the second horizontal direction Y. The bottom wall of the upper cover 22 is provided with two first protrusions 222 along the vertical direction Z. The two first protrusions 222 are arranged on either side of the second groove 232 along the second horizontal direction Y. The two first protrusions 222 correspond one-to-one with the two recessed grooves 211. In this embodiment, this arrangement facilitates the rapid positioning and installation of the base 21 and the upper cover 22; it also limits the relative movement of the base 21 and the upper cover 22 in the horizontal direction.

[0042] Optionally, a first limiting groove 241 is provided on the bottom wall of each of the two sinks 211, and a second limiting groove 242 is provided on each of the two first protrusions 222. The two first limiting grooves 241 correspond to each other one by one and are surrounded by the two second limiting grooves 242 to form two limiting holes. In this embodiment, the provision of limiting holes can increase the contact area between the casting seat 2 and the rotating shaft 32, thereby preventing the casting seat 2 from being subjected to excessive force locally, thereby causing damage to the casting seat 2. The limiting hole is formed by the first limiting groove 241 and the second limiting groove 242. This arrangement can facilitate the installation of the rotating shaft 32 on the one hand, and on the other hand, it can facilitate the inspection of the inner wall of the limiting hole to check for cracks in the first limiting groove 241 and the second limiting groove 242.

[0043] Optionally, the top wall of the base 21 is provided with two recessed fixing grooves 212 along the vertical direction Z. The two fixing grooves 212 are respectively provided along the second horizontal direction Y on the side away from each other of the two limiting holes. The bottom wall of the upper cover 22 is provided with two second protrusions 223 along the vertical direction Z. The two second protrusions 223 are respectively provided along the second horizontal direction Y on the side away from each other of the two limiting holes. The two second protrusions 223 are inserted into the two fixing grooves 212 in a one-to-one correspondence, and the second protrusions 223 and the corresponding fixing grooves 212 are arranged to form a prismatic hole. The two prismatic holes are connected to the two limiting holes in a one-to-one correspondence. Prismatic protrusions 33 are respectively provided at both ends of the rotating shaft 32 along the second horizontal direction Y. The two prismatic protrusions 33 are respectively inserted into the two prismatic holes in a one-to-one correspondence. In this embodiment, the diamond-shaped protrusions provided on the rotating shaft 32 are inserted into the diamond-shaped holes. This configuration can prevent the rotating shaft 32 from rotating about its axis relative to the casting seat 2, thereby avoiding wear between the rotating shaft 32 and the wall of the limiting hole. Specifically, the prism hole can be a triangular prism hole, a quadrangular prism hole, a pentagonal prism hole, etc. Specifically, the wheel body 31 rotates on the rotating shaft 32 .

[0044] Optionally, along the vertical direction Z, the distance between the end of the support rod 1 away from the support platform and the support platform is a preset value a, and the distance between the highest point of the wheel body 31 and the support platform is a preset value b, where a>b. In this embodiment, when the upper cover 22 is damaged or removed, if the wire rope accidentally slips out of the wire groove, since a>b, the lateral rigidity provided by the support rod 1 can block the wire rope, preventing the gravity energy storage system from experiencing problems such as heavy objects falling or serious spatial displacement.

[0045] Optionally, the base 21 is an integrally formed part, and the upper cover 22 is an integrally formed part. In this embodiment, the base 21 and the upper cover 22 are cast by a mold, which can improve the manufacturing accuracy on the one hand and reduce the manufacturing cost on the other hand.

[0046] Optionally, along the vertical direction Z, the bottom wall of the accommodating hole 23 is recessed with an oil storage tank 213, in which lubricating oil is stored, and the wheel body 31 is partially located in the oil storage tank 213. In this embodiment, the oil storage tank 213 is a groove feature under the wheel body 31, with a lower middle position and higher ends on both sides. The oil storage tank 213 is used to store flowing lubricating oil, which is mainly used to lubricate the wire rope and the wheel body 31 groove to prevent the wire rope and the wheel body 31 groove from rusting and prolonging the service life. The oil storage tank 213 can be regularly filled with lubricating oil. When the wheel body 31 rotates, it can come into contact with the lubricating oil in the oil storage tank 213 to achieve lubrication, thereby penetrating through the wheel body 31 to the wire rope, achieving lubrication of the wire rope and the fixed pulley 3. Furthermore, the lubricating oil in the oil storage tank 213 can be monitored for liquid level or automatically filled by other automatic oil filling devices, thereby achieving automated and intelligent oil filling and lubrication.

[0047] Optionally, a plurality of support rods 1 are provided, and the plurality of support rods 1 are respectively provided on both sides of the accommodating hole 23 along the second horizontal direction Y. In this embodiment, this arrangement can improve the stability of the counter-fixation between the base 21 and the upper cover 22 .
