Ensure sufficient electrolyte in the battery and ensure the cycle life and deep discharge performance during battery use.
[0015] This embodiment is specifically a lead-acid battery acid pumping device, which includes an acid pumping pipe 1, a pipe wall 2, an opening of the pipe wall 2, and an adjustable acid pumping structure. The acid pumping pipe 1 is connected to the adjustable acid pumping structure, the pipe wall 2 is arranged on the outer sides of the adjustable acid pumping structure and the acid pumping pipe 1, and the opening of the pipe wall 2 is arranged at one end of the adjustable acid pumping structure.
[0016] The above-mentioned solution provided by this application can effectively reduce the problem of different electrolyte contents in different batteries caused by acid pumping through fixed pipelines by setting an acid pumping device in the acid pumping step during production, and ensure sufficient electrolyte in the electrode group. During use, when the liquid is higher than the opening of the pipe wall 2, the device will continuously pump the liquid. When the liquid is lower than the pipe orifice wall, air will pass through the gap 9 of the acid pumping head to keep the liquid level below the opening of the pipe wall 2. By adjusting the height of the acid pumping head, the contact height h between the opening of the pipe wall 2 and the electrode group is adjusted to control the liquid level height. Adding this structure to the battery acid pumping pipe 1 can achieve the expected effect and make the battery have sufficient electrolyte.
[0017] Further, the acid pumping structure is adjustable and includes an adjustable acid pumping head. The adjustable acid pumping head includes an adjusting head 7 and a threaded structure 8. The adjusting head 7 is connected to the pipe wall 2 through the threaded structure 8.
[0018] The contact height h between the opening of the pipe wall 2 and the electrode group, as Figure 2 shown, an inclined inlet 5 is also provided on the acid pumping pipe, which is a chamfered structure for facilitating the insertion of the pipe.
[0019] Further, the device also includes a rubber ring 6, and the rubber ring 6 is arranged between the acid pumping pipe 1 and the pipe wall 2.
[0020] Based on the above technical solution, the rubber ring 6 provided in the device can improve the sealing performance of the device and the compatibility between the rubber ring 6 and the acid pumping pipe 1.
[0021] Further, the device also includes a cross protection structure 4. The cross protection structure 4 is arranged at the position of the opening of the pipe wall 2 and is a cross-shaped strip plate structure. The separator of the electrode group is prone to tearing under the action of vacuum negative pressure. The cross protection directly presses on the separator to reduce the possibility of being torn.
