Description

Technical Field

[0001] This utility model relates to the field of battery separator technology, and in particular to a short-circuit protection separator device for lead-acid battery energy storage. Background Technology

[0002] The main function of the separator is to prevent the positive and negative plates from directly contacting each other, causing an internal short circuit. There are various types of battery separators, the most common being rubber separators, PP separators, PE separators, PVC separators, and AGM separators. The separator in a lead-acid battery plays a crucial role in the battery, and its performance and quality directly affect the battery's capacity, charge-discharge cycle life, and self-discharge performance. The quality of the battery separator directly affects the battery's capacity. Poor-quality separators have larger pores, which can cause the battery's capacity to gradually decrease and eventually fail. Separators with high resistance can also cause the battery's operating voltage to drop during discharge, resulting in a lower discharge capacity.

[0003] Over long-term use, the micropores in the separators of lead-acid batteries gradually become clogged, leading to a decline in overall battery performance. Therefore, after prolonged use, lead-acid batteries require regular replacement and maintenance of the separators. However, currently, lead-acid battery separators are generally fixed directly inside the battery casing, making replacement somewhat cumbersome. Furthermore, during the manufacturing process, when no electrolyte is added inside the battery casing, the separators inside the casing are directly exposed to the air. This allows dust and impurities from the air to enter and clog the micropores in the separators.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a short-circuit protection separator device for lead-acid battery energy storage, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a short-circuit protection separator device for lead-acid battery energy storage, comprising a connecting frame, through openings on the front and rear sides of the outer wall of the connecting frame, a sliding frame slidably connected inside the connecting frame, a separator body fixedly connected inside the sliding frame, countersunk holes arranged symmetrically and linearly on the front side of the outer wall of the sliding frame, and a compression nut being rotatably pressed onto the inner wall of each countersunk hole.

[0007] As a further technical solution of this utility model, threaded sleeves are fixedly connected to the front side of the outer wall of the connecting frame in a symmetrical linear arrangement, and the compression nut is threadedly connected to the threaded sleeves.

[0008] As a further technical solution of this utility model, the connecting frame, the sliding bracket, the threaded sleeve and the compression nut are all made of fluororubber.

[0009] As a further technical solution of this utility model, a pull handle is fixedly connected to the upper end of the outer wall of the sliding frame.

[0010] As a further technical solution of this utility model, sliding frames are fixedly installed on the front and rear sides of the outer wall of the connecting frame, and protective plates are slidably connected to the inner walls of the front and rear sliding frames.

[0011] As a further technical solution of this utility model, each of the two protective plates has a pull handle fixedly connected to the back side of its outer wall.

[0012] This utility model provides a short-circuit protection separator device for lead-acid battery energy storage, which has the following advantages compared with the prior art:

[0013] 1. This utility model uses a sliding connection between a sliding frame and a connecting frame to install the separator body inside the connecting frame. The separator body prevents the positive and negative plates inside the battery casing from directly contacting each other, thus avoiding short circuits inside the battery casing. Furthermore, personnel can rotate the compression nut to make it rotate forward and compress the countersunk hole on the sliding frame, thereby pressing the rear side of the outer wall of the sliding frame against the rear side of the inner wall of the connecting frame, thereby increasing the sealing between the left and right sides of the connecting frame. At the same time, when it is necessary to replace the separator body, personnel can unscrew the compression nut to release the device from fixing the sliding frame, and then remove the sliding frame to replace the separator body, thereby increasing the convenience of the device during use.

[0014] 2. When this utility model is in use, if no electrolyte is added inside the battery casing, personnel can insert a protective plate into the sliding frame to prevent the separator body from being directly exposed to the air, which would cause a large amount of dust and impurities in the air to enter the micropores of the separator body and block the micropores. This protects the left and right sides of the separator body and improves the practicality of the device during use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution for a short-circuit protection separator device for lead-acid battery energy storage: it includes a connecting frame 100, with through openings 110 on the front and rear sides of the outer wall of the connecting frame 100, a sliding frame 200 slidably connected inside the connecting frame 100, and a separator body 210 fixedly connected inside the sliding frame 200. The front side of the outer wall of the sliding frame 200 has countersunk holes 300 arranged linearly on the left and right sides, and each countersunk hole 300 has a compression nut 320 rotatably pressed on the inner wall. The device installs the separator body 210 into the connecting frame 100 through the sliding connection between the sliding frame 200 and the connecting frame 100. The separator body 210 prevents the positive and negative plates inside the battery casing 1 from directly contacting each other, thus avoiding short circuit inside the battery casing 1. Threaded sleeves 310 are symmetrically and linearly arranged on the front side of the outer wall of the connecting frame 100. A compression nut 320 is threadedly connected to the threaded sleeve 310. After the sliding frame 200 is inserted into the connecting frame 100, a person can rotate the compression nut 320. The forward rotation of the compression nut 320 compresses the countersunk hole 300 on the sliding frame 200, thereby pressing the rear side of the outer wall of the sliding frame 200 against the rear side of the inner wall of the connecting frame 100, increasing the sealing between the left and right sides of the connecting frame 100. The connecting frame 100, sliding frame 200, threaded sleeves 310, and compression nuts 320 are all made of fluororubber, which has excellent corrosion resistance, thus improving the service life of the connecting frame 100, sliding frame 200, threaded sleeves 310, and compression nuts 320. A pull handle 400 is fixedly connected to the upper end of the outer wall of the sliding frame 200, allowing for easy sliding of the sliding frame 200.

[0023] like Figure 1 and Figure 2As shown, sliding frames 500 are fixedly installed on the front and rear sides of the outer wall of the connecting frame 100. Protective plates 510 are slidably connected to the inner walls of both sliding frames 500. The left and right sides of the partition body 210 can be protected by inserting the protective plates 510 into the sliding frames 500. Pull handles 520 are fixedly connected to the back side of the outer walls of both protective plates 510. Pull handles 400 facilitate the sliding of the protective plates 510 by personnel.

[0024] The working principle of this utility model is as follows: In use, the connecting frame 100 is installed inside the battery housing 1. The device uses the sliding bracket 200 to slide and connect with the connecting frame 100 to install the separator body 210 inside the connecting frame 100. The separator body 210 prevents the positive and negative plates inside the battery housing 1 from directly contacting each other, thus avoiding short circuits inside the battery housing 1. Pulling the handle 400 allows personnel to easily slide the sliding bracket 200. The connecting frame 100, sliding bracket 200, threaded sleeve 310, and compression nut 320 are all made of fluororubber, which has good corrosion resistance. Yes, this can improve the service life of the connecting frame 100, sliding frame 200, threaded sleeve 310, and compression nut 320. Furthermore, by rotating the compression nut 320 forward, personnel can compress the countersunk hole 300 on the sliding frame 200, causing the rear outer wall of the sliding frame 200 to press against the rear inner wall of the connecting frame 100, increasing the sealing between the left and right sides of the connecting frame 100. When the separator body 210 needs to be replaced, personnel can unscrew the compression nut 320 to release the fixing device of the sliding frame 200, and then remove the sliding frame 200 to replace the separator body 210. Simultaneously, when no electrolyte is added inside the battery casing 1, personnel can easily slide the protective plate 510 by inserting it into the sliding frame 500 and pulling the handle 400, thus protecting the left and right sides of the separator body 210.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
