Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a transport vehicle for a ramp-type gravity energy storage system. Background Technology

[0002] More than 20 provinces, municipalities, and autonomous regions in my country have issued policies on new energy energy storage, with energy storage allocation ratios ranging from 10% to 20% and allocation durations ranging from 2 to 4 hours. Between 2020 and 2022, new energy energy storage has generated significant demand for energy storage capacity, becoming the biggest driving force for the development of energy storage in China. Gravity energy storage has advantages such as low construction cost, low maintenance cost, high conversion rate, short construction period (1.5-2 years), abundant site resources, and long lifespan. It utilizes surplus electricity to lift heavy objects from a low position to a high position, converting electrical energy into potential energy. When discharge is needed, the potential energy is converted back into electrical energy. Existing pumped hydro storage is essentially also gravity energy storage, using flowing water as its storage medium to complete the mutual conversion between gravitational potential energy and electrical energy. This solid-state version of gravity potential energy storage offers large-scale, long-term energy storage capabilities with low construction costs and short construction timelines.

[0003] Therefore, existing energy storage vehicles use gravitational potential energy to convert into electrical energy for storage and use. However, existing energy storage transport vehicles move by grabbing cables, which is inconvenient to replace when passing through multiple cable segments. Utility Model Content

[0004] To address the issue of easy cable replacement in traditional transport trolleys, this utility model provides a transport trolley for a slope-type gravity energy storage system, comprising:

[0005] The main body of the vehicle and the clamping unit;

[0006] The main body of the trolley includes a base plate, drive wheels and baffles. There are two or more drive wheels, which are rotatably mounted on the bottom of the base plate. The drive wheels are suitable for sliding on a multi-power segment gravitational potential energy track. The baffles are provided with a preset space around the top of the base plate, which is suitable for placing heavy blocks.

[0007] There are two clamping units, which are respectively located at the front and rear ends of the trolley body. The clamping units are suitable for clamping the cable of the multi-power segment gravitational potential energy track and driving the trolley body to move.

[0008] In one possible implementation, the clamping unit is positioned at the middle of the front end of the trolley body.

[0009] In one possible implementation, the clamping unit further includes a clamping bracket and a clamping cylinder.

[0010] The clamping bracket is located at the front end and / or rear end of the trolley body and is capable of clamping the cable of the multi-power segment gravitational potential energy track.

[0011] The clamping cylinder is mounted on the clamping bracket and drives the clamping bracket to loosen or tighten.

[0012] In one possible implementation, the clamping bracket includes: a clamping rod, a rotating rod, and a connecting member;

[0013] The connector is located at the front end of the trolley body and overlaps the base plate. The connector is a plate-shaped structure with a first connecting hole and a second connecting hole. The opening direction of the first connecting hole is perpendicular to the opening direction of the second connecting hole.

[0014] The rotating rod is a rod-shaped structure that passes through the first connecting hole and is rotatably attached to the base plate;

[0015] There are two clamping rods, which are staggered and clamp the cable of the multi-power segment gravitational potential energy track.

[0016] In one possible implementation, one end of the clamping rod is a clamping end and the other end is a driving end;

[0017] The clamping rod has a first driving hole at its driving end, and the output end of the clamping cylinder passes through the first driving hole to drive the two clamping rods to clamp the cable of the multi-power segment gravitational potential energy track.

[0018] One possible implementation also includes: a transmission rod;

[0019] The transmission rod passes through the second drive hole and the second connection hole of the two clamping rods, and the two clamping rods rotate around the transmission rod to clamp or release the cable of the multi-power segment gravitational potential energy track.

[0020] One possible implementation also includes: a protective bracket;

[0021] The protective bracket has a hollow structure and is fixedly connected to the front end of the trolley body;

[0022] The clamping unit is mounted on the protective bracket.

[0023] In one possible implementation, the clamping end of the clamping rod is arc-shaped.

[0024] In one possible implementation, the inner side of the clamping end is provided with multiple anti-slip textures.

[0025] The beneficial effects of the transport trolley in the inclined gravity energy storage system of this application embodiment are as follows: The trolley body is connected to the cable drive of the multi-power segment gravity potential energy track through clamping units, enabling the excitation motor to pull the trolley body upwards via the cable. Furthermore, when the trolley body is descending, it can drive the cable to move, thereby enabling the dual-power motor to generate electricity. Specifically, the track in this application is a multi-power segment track. Clamping units are respectively provided at the front and rear ends of the trolley body. When changing different track segments, the clamping unit at the front of the trolley body releases the cable, while the clamping unit at the rear of the trolley body clamps the cable, allowing the trolley body to continue moving upwards. When the trolley body moves to another track segment, the clamping unit at the front of the trolley body grips the cable, while the clamping unit at the rear of the trolley body releases the cable, completing the movement and replacement of the trolley body on the multi-power segment gravity potential energy track.

[0036] like Figures 1-3 As shown, the transport trolley of the inclined gravity energy storage system of this application embodiment includes: a trolley body 100 and a clamping unit 200. The trolley body 100 includes a base plate, drive wheels 300 and baffles. There are two or more drive wheels 300, which are rotatably arranged at the bottom of the base plate. The drive wheels 300 are suitable for sliding on the multi-power segment gravity potential energy track. The baffles are provided with a preset space around the top of the base plate, which is suitable for placing heavy blocks. There are two clamping units 200, which are respectively arranged at the front end and rear end of the trolley body 100. The clamping units 200 are suitable for clamping the cable of the multi-power segment gravity potential energy track and driving the trolley body 100 to move.

[0037] In this specific embodiment, the trolley body 100 is connected to the cable drive of the multi-power segment gravity potential energy track via the clamping unit 200, enabling the excitation motor to pull the trolley body 100 upwards via the cable. Furthermore, when the trolley body 100 is descending, it can move the cable, thereby generating electricity for the dual-power motor. Specifically, the track in this application is a multi-power segment track. Clamping units 200 are respectively provided at the front and rear ends of the trolley body 100. When changing different track segments, the clamping unit 200 at the front of the trolley body 100 releases the cable, while the clamping unit 200 at the rear of the trolley body 100 clamps the cable, allowing the trolley body 100 to continue moving upwards. When the trolley body 100 moves to another track segment, the clamping unit 200 at the front of the trolley body 100 grips the cable, while the clamping unit 200 at the rear of the trolley body 100 releases the cable, completing the movement and replacement of the trolley body 100 on the multi-power segment gravity potential energy track.

[0038] In one specific embodiment, the clamping unit 200 is located at the middle of the front end of the trolley body 100. By placing the clamping unit 200 at the middle of the front end of the trolley body 100, the trolley can be subjected to uniform force under the drive of the cable, reducing the possibility of the trolley deviating or swaying during movement, and improving the stability and safety of the trolley operation.

[0039] In one specific embodiment, the clamping unit 200 further includes a clamping bracket and a clamping cylinder 340. The clamping bracket is disposed at the front end and / or rear end of the trolley body 100 and is capable of clamping the cable of the multi-power segment gravity potential energy track. The clamping cylinder 340 is disposed on the clamping bracket and drives the clamping bracket to release or grip.

[0040] In this specific embodiment, the clamping cylinder 340 and the clamping bracket are located at the front and rear ends of the trolley body 100. The clamping cylinder 340 drives the clamping bracket to grip or release the cable, thereby completing the exchange of the trolley body 100 between two adjacent track sections.

[0041] In one specific embodiment, the clamping bracket includes: a clamping rod 210, a rotating rod 260, and a connector 230. The connector 230 is disposed at the front end of the trolley body 100 and overlaps the base plate. The connector 230 is a plate-shaped structure with a first connecting hole and a second connecting hole. The opening direction of the first connecting hole is perpendicular to the opening direction of the second connecting hole. The rotating rod 260 is a rod-shaped structure that passes through the first connecting hole and is rotatably overlapped on the base plate. There are two clamping rods 210, which are staggered to clamp the cable of the multi-power segment gravity potential energy track.

[0042] In this specific embodiment, the first connecting hole of the connector 230 allows the connector 230 to rotate along the movement direction of the trolley body 100. The second connecting hole provides a rotational intersection point for the two clamping rods 210 to clamp the cable. The rotating rod 260 passes through the first connecting hole and overlaps the front or rear end of the bottom plate of the trolley body 100, ensuring that the connector 230 is rotatably connected to the trolley body 100 through the rotating rod 260. There are two clamping rods 210, which are in an "S" shape. One end is connected to the clamping cylinder 340, and the other end is used to clamp the cable.

[0043] Two clamping rods 210 are staggered to form an "X"-shaped combination structure to grip the cable.

[0044] In one specific embodiment, one end of the clamping rod 210 is a clamping end and the other end is a driving end. The driving end of the clamping rod 210 has a first driving hole. The output end of the clamping cylinder 340 passes through the first driving hole and drives the two clamping rods 210 to clamp the cable of the multi-power segment gravitational potential energy track.

[0045] In this specific embodiment, the clamping cylinder 340 is disposed between the driving ends of the two clamping rods 210. The output ends of the clamping cylinder 340 on opposite sides are respectively connected to the driving ends of the two clamping rods 210. When the output ends of the clamping cylinder 340 move outward, the distance between the driving ends of the two clamping rods 210 increases, thereby reducing the distance between the clamping ends of the two clamping rods 210, which enables the cable to be clamped.

[0046] In one specific embodiment, the system further includes a transmission rod 250, which passes through the second drive hole and the second connecting hole of the two clamping rods 210. The two clamping rods 210 rotate around the transmission rod 250 to clamp or release the cable of the multi-power segment gravitational potential energy track. The transmission rod 250 provides a fixed axis for the rotation of the clamping rods 210, ensuring the synchronicity and coordination of the movements of the two clamping rods 210, making the motion trajectory of the clamping end more stable, and improving the accuracy of the clamping and releasing actions. At the same time, the transmission rod 250 connects the clamping rods 210 to the connector 230, enhancing the stability and rigidity of the overall structure of the clamping bracket, enabling it to withstand greater clamping force, and ensuring that the clamping bracket will not deform or be damaged due to excessive force during the operation of the trolley.

[0047] In one specific embodiment, it further includes: a protective bracket 400, which has a hollow structure and is fixedly connected to the front end of the trolley body 100, and a clamping unit 200 is disposed on the protective bracket 400.

[0048] In one specific embodiment, the clamping end of the clamping rod 210 is arc-shaped. The arc-shaped clamping end can better fit the surface of the cable, increasing the contact area during clamping. Furthermore, the cross-sectional diameter of the two clamping ends of the clamping rods 210 when aligned is smaller than the cross-sectional diameter of the cable. This allows the cable to be clamped, enabling the cable to drive the trolley body 100 to move.

[0049] In one specific embodiment, the inner side of the clamping end is provided with multiple anti-slip textures to improve the stability of the clamping unit 200 clamping the cable. Even if there is slight vibration or shaking during the operation of the trolley, it can effectively prevent the cable from slipping off the clamping end, greatly improving the reliability and safety of clamping, ensuring that the transport trolley can move stably with the cable, and ensuring the normal operation of the entire gravity energy storage system.

[0050] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
