Technical Field

[0001] This utility model relates to the field of vanadium redox flow battery technology, and in particular to a protective shell for vanadium redox flow batteries suitable for outdoor environments. Background Technology

[0002] Vanadium redox flow batteries are an energy storage technology that stores and releases electrical energy through changes in the valence state of vanadium ions. They have advantages such as ultra-long cycle life, high safety, and long-term energy storage capacity, and are suitable for large-scale outdoor energy storage scenarios such as renewable energy storage and grid peak shaving.

[0003] The electrolyte in vanadium redox flow batteries is vanadium sulfate solution, which has strong oxidizing and corrosive properties. The protective casing must withstand such chemical corrosion over a long period to prevent electrolyte leakage due to material degradation. For example, traditional metal casings are easily corroded, while polymers such as modified PVC and carbon fiber composites have become the mainstream choice due to their excellent chemical resistance.

[0004] Although existing battery protective casings possess a certain degree of resistance to strong corrosion, impact forces are unavoidable during actual battery placement. These impact forces are transmitted through the casing to the interior, causing damage to the battery components and affecting their normal operation and lifespan. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 - Figure 4As shown, this utility model provides a protective shell for vanadium redox flow batteries suitable for outdoor environments, including a shell body 1. Shock-absorbing protective components 2 are connected to the bottom of both sides of the shell body 1. Each shock-absorbing protective component 2 includes a mounting bracket 201. Side ears 202 are connected to the top of the front and rear ends of the mounting bracket 201. A damper 203 is connected to the center of the bottom of the mounting bracket 201. A fixing rod 204 is inserted into the center of the interior of the mounting bracket 201. First springs 205 are sleeved on both sides of the fixing rod 204. Movable blocks 206 are connected to the inner sides of both sets of first springs 205. Sliding holes 207 are opened inside the movable blocks 206. The bottom of the movable blocks 206 is connected to... A first rotating shaft 208 is connected, and a rotating rod 209 is connected to the surface of the first rotating shaft 208. A second rotating shaft 210 is connected to one side of the rotating rod 209. A base plate 211 is connected to the bottom surface of the second rotating shaft 210. The inner wall of the sliding hole 207 is in contact with the outer surface of the fixed rod 204. The moving block 206 is slidably connected to the fixed rod 204 through the sliding hole 207. The moving block 206 and the first spring 205 form an elastic structure. The moving block 206 is rotatably connected to the rotating rod 209 through the first rotating shaft 208. The side ear 202 is fixed to the surface of the outer shell body 1 by bolts. The side ear 202 is fixedly connected to the fixed frame 201.

[0023] The effect achieved in embodiment 1 is that when the outer casing 1 is used outdoors and placed on the ground, the base plate 211 will first contact the ground. The impact force generated at this time will cause the base plate 211 to press upward, and the base plate 211 will rotate through the second pivot 210 and the rotating rod 209, thereby driving one side of the rotating rod 209 to rotate through the first pivot 208 and the moving block 206. This rotation pushes the moving block 206 to slide on the surface of the fixed rod 204 through the sliding hole 207, and compresses the first spring 205. With the synergistic effect of the damper 203, a shock absorption and buffering effect can be achieved, effectively protecting the battery inside the outer casing 1. In addition, the shock absorption and protection component 2 has a disassembly function. When replacement is required, simply remove the bolt from the side lug 202 and install the new shock absorption and protection component 2. In this way, the impact force can be prevented from being transmitted through the outer casing 1 to the interior, thereby preventing impact damage to the battery assembly.

[0024] Example 2, as Figure 4 and Figure 5As shown, a storage component 3 is located at the bottom center of the outer shell body 1. The storage component 3 includes a storage slot 301, and a storage box 302 is disposed inside the storage slot 301. Slide grooves 303 are provided on both sides of the bottom of the storage box 302. A slider 304 is connected to the inner bottom of the storage slot 301. A handle 305 is connected to the front center of the storage box 302. Fixing blocks 306 are connected to the inner walls of both sides of the outer shell body 1 near the storage slot 301. Slots 307 are provided inside the fixing blocks 306. Each side surface is connected to a connecting block 308. A second spring 309 is connected inside the connecting block 308. A push plate 310 is connected to one side of the second spring 309. An insert block 312 is connected to one side of the push plate 310. A lever block 311 is connected to the center of the front end of the push plate 310. An oblique opening is provided on the surface of the insert block 312. The insert block 312 and the slot 307 form an interlocking connection. The storage box 302 is slidably connected to the slider 304 through the slot 307. The push plate 310 and the second spring 309 form an elastic structure.

[0025] The effect achieved by embodiment 2 is that when it is necessary to take out the tools or connecting wires in the storage box 302 for use, the two sets of levers 311 can be pushed inward at the same time, so that the levers 311 can push the push plate 310 to squeeze the second spring 309 and drive the insert 312 to be pulled out from the slot 307 of the fixing block 306. Then, the storage box 302 can be pulled outward, and the slide groove 303 at the bottom of the storage box 302 can be slid out by the slider 304. Then, the accessories in the storage box 302 can be taken out for use. When it is necessary to close the storage box 302, the storage box 302 can be pushed into the storage groove 301. The angled opening of the insert 312 will automatically retract after being squeezed. When the storage box 302 is completely pushed into the storage groove 301, the second spring 309 will push the push plate 310 to drive the insert 312 to be inserted into the slot 307 for fixation. It allows for convenient storage of commonly used connecting cables or other tools, eliminating the need for separate placement and making them easy to access, thus increasing the practicality of the main body 1.

[0026] Working principle: When the outer shell 1 is used outdoors and placed on the ground, the base plate 211 will first contact the ground. The impact force will cause the base plate 211 to press upward, and drive the moving block 206 to press the first spring 205. Together with the damper 203, it achieves the function of shock absorption and buffering, thus protecting the battery inside the outer shell 1 and preventing the impact force from being transmitted through the outer shell 1 to the inside, thereby causing impact damage to the battery components. When using the battery outdoors, the storage box 302 inside the outer shell 1 can conveniently store commonly used connecting wires or other tools without the need for separate placement. It is also more convenient to access, increasing the practicality of the outer shell 1.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the protection scope of the technical solution of this utility model.
