Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, specifically relating to a modular energy storage container mechanism for photovoltaic power plants. Background Technology

[0002] A core issue with photovoltaic power plants is the instability of power generation. Modular energy storage containers can store surplus electricity when the sun is strongest and power generation is highest at midday, storing unused electricity and releasing it to grid users in the evening, at night, or on cloudy days when power generation is insufficient.

[0003] Modular energy storage containers typically consist of a battery management system, an energy conversion system, and a temperature control system. The battery management system is responsible for monitoring the voltage, temperature, and health status of each battery cell to ensure safety. When a battery has a problem and needs to be repaired and / or replaced, the existing energy storage container structure requires disassembling the back panel of the container and manually moving the battery trays out, which is not only inefficient but also requires a lot of manpower.

Detailed Implementation

[0020] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Please see Figures 1-4 According to one embodiment of the present invention, a modular energy storage container mechanism for a photovoltaic power station includes a shell assembly 1, which includes a main shell 101 and a storage box 102, wherein the storage box 102 for storing batteries is disposed inside the main shell 101; a loading assembly 2, which includes a loading frame 201 and batteries 202, wherein the loading frame 201 is slidably arranged in the storage box 102, and a plurality of batteries 202 are assembled in the loading frame 201; and a traction assembly 3, which includes a guide rail 301, a sliding table 302, a fixed base 305, a limiting rod 306, and a side sliding table 307, wherein the guide rail 301 is fixedly assembled to the bottom side of the main shell 101. The slide table 302 is slidably mounted on the guide rail 301. A fixed base 305 is also fixedly mounted on the slide table 302. A limit rod 306 is fixedly mounted on the fixed base 305. The side slide table 307 is slidably mounted on the fixed base 305 along the arrangement direction of the limit rod 306 axis. The shell assembly 1 also includes a support plate 103, positioning holes 104 and side sliding grooves 105. The support plate 103 is fixedly mounted in the storage box 102. The support plate 103 is used to support the loading frame 201. A plurality of positioning holes 104 and side sliding grooves 105 are arranged in an array on the support plate 103. A limit pin matching the positioning hole 104 is provided at the bottom of the loading frame 201.

[0022] In practical application, when using the modular energy storage container mechanism of this photovoltaic power station, the main structure consists of a main shell 101. A storage box 102 on one side of the main shell 101 is used to fill batteries 202 for storing electrical energy. Several loading racks 201 are arrayed within the storage box 102. Each loading rack 201 is equipped with several batteries 202. The bottom of each loading rack 201 is also provided with a limiting pin that matches a positioning hole 104. When the loading rack 201 is assembled in the storage box 102, its bottom limiting pin is inserted into the positioning hole 104 to limit the movement of the loading rack 201 within the box. A movable... The movable door panel, when in the open state, can lift the loading rack 201 through the traction component 3 and pull it out from the inner cavity of the storage box 102, making it convenient for maintenance personnel to inspect and replace the battery 202. The guide rail 301 in the traction component 3 is fixedly set at the bottom of the main housing 101. The slide table 302 is slidably assembled on the guide rail 301, and a fixed base 305 is also fixedly set on the slide table 302. The side slide table 307 is slidably sleeved on the limiting rod 306 to limit the movement direction of the side slide table 307. The width of the side slide table 307 is smaller than the width of the side slide groove 105 so that the side slide table 307 can slide out of the side slide groove 105.

[0023] Please see Figure 4 In a preferred embodiment of the present invention, the traction assembly 3 further includes a first drive motor 303 and a first drive screw 304. The first drive motor 303 is fixedly mounted in the main housing 101, and the first drive screw 304 is rotatably arranged in the main housing 101. One end of the first drive screw 304 is fixedly connected to the movable shaft of the first drive motor 303, and the other end of the first drive screw 304 is engaged with the slide table 302.

[0024] In practical application, the first drive motor 303 is fixedly installed in the main housing 101, and its movable shaft is coaxially fixedly connected with the first drive screw 304, so that during the driving process, the first drive screw 304 can synchronously engage and drive the slide 302 to move, thereby controlling the sliding position of the slide 302 on the guide rail 301. Since the first drive screw 304 is driven by a servo motor, the sliding position of the slide 302 can be precisely controlled.

[0025] Please see Figure 4 In a preferred embodiment of this embodiment, the traction component 3 further includes a top support cylinder 308 and an anti-slip table 309. A plurality of top support cylinders 308 are arranged in an array on the side slide table 307, and the anti-slip table 309 is fixedly mounted on the movable shaft of the top support cylinder 308.

[0026] In practical application, several top support cylinders 308 are fixedly mounted on the side slide 307, and an anti-slip table 309 is also fixedly mounted on it. When the slide 302 drives the side slide 307 to move to the bottom of the side slide groove 105, the top support cylinders 308 in the activated state lift the anti-slip table 309 so that the anti-slip table 309 passes through the side slide groove 105 and abuts against the bottom of the loading frame 201. This causes the limiting pin at the bottom of the loading frame 201 to disengage from the positioning hole 104 after it is raised. At this time, by driving the side slide 307 to slide along the limiting rod 306, the anti-slip table 309 can push the supported loading frame 201 out of the storage box 102 cavity, thereby pushing the loading frame 201 to the outside of the main housing 101 for easy inspection.

[0027] Please see Figure 4 In a preferred embodiment of the present invention, the traction assembly 3 further includes a traction rod 310, a push block 311, a second drive screw 312, and a second drive motor 313. The traction rod 310 is slidably arranged in the main housing 101 and slidably inserted into the side slide table 307. Push blocks 311 are fixedly assembled at both ends of the traction rod 310. The second drive screw 312 is fixedly arranged in the main housing 101, and one end of the second drive screw 312 is engaged with the push block 311. The other end of the second drive screw 312 is fixedly connected to the movable shaft of the second drive motor 313.

[0028] In practical application, one end of the traction rod 310 is slidably mounted on the side slide table 307, and the push block 311 at the other end of the traction rod 310 is slidably mounted in the main housing 101. The push block 311 and the second drive screw 312 are engaged and connected, so that the second drive motor 313 can drive the side slide table 307 to slide directionally along the fixed base 305 in the driving state, and then cooperate with the anti-slip table 309 to push the raised loading frame 201 to the outside of the storage box 102.

[0029] The present invention provides a modular energy storage container mechanism for photovoltaic power plants in the above embodiments. By providing a plurality of loading racks 201 for loading batteries 202 inside the storage box 102, and providing directional sliding slides 302 and side slides 307 at the bottom of the main shell 101, any set of loading racks 201 can be independently lifted and pushed out, which facilitates maintenance personnel to inspect and replace batteries.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
