Multifunctional liquid injection cap of lead acid storage battery for traction

Abstract

The invention relates to a multifunctional liquid injection cap of a lead acid storage battery for traction, comprising a shell (1), a liquid level control device and a cap cover, wherein the top of the cap cover is provided with a liquid injection hole (III), and the lateral surface of the cap cover is provided with an exhaust hole (IV), a panel (12) and a floater viewing port translucent cover (4). The multifunctional liquid injection cap is characterized in that the liquid level control device comprises a floater (9) which measures liquid level height and can float up and down, a liquid adding choke plug (10) and a floater connecting bar (8); the liquid injection hole (III) is connected with a T joint (3) and utilizes an overhead tank to inject liquid from the T joint (3) through a connecting tube, and then the injected liquid enters a liquid storage tank (V), the ascending and the descending of the liquid level is measured by the floater (9), and the choke plug (10) leaves or opens an upper liquid port, thus the multifunctional liquid injection cap automatically supplements liquid into the lead acid storage battery. The invention can automatically control and supplement the liquid level and prevent the lead acid storage battery from being damaged due to the liquid lack, thereby prolonging the service life of the lead acid storage battery.

Description

technical field [0001] The invention relates to a lead-acid battery, in particular to a liquid injection cap used for an automatic liquid injection system of a traction lead-acid battery. Background technique [0002] With the improvement of people's living standards, the requirements for automation are getting higher and higher. In terms of lead-acid batteries for traction, there is no maintenance-free type at home or abroad at present. During the use of the batteries, users need to frequently replenish the batteries for maintenance. Our country is still using ordinary liquid injection caps, which need to be added manually during use, which is a waste of labor and is also restricted by the operator's sense of responsibility. It is very easy to add less liquid or leak liquid, resulting in reduced battery life. Although there are automatic liquid injection systems in foreign countries, the liquid injection cap in the automatic liquid injection system has only one liquid fill...

AI Technical Summary

Problems solved by technology

In our country, the common liquid injection cap is still used. During the use, the liquid needs to be added manually, which not only wastes labor, but also is restricted by the operator's sense of responsibility. Although there are automatic liquid injection systems in foreign countries, the liquid injection cap in the automatic liquid injection system has only one liquid filling port, one vent hole, one observation port and one measurement port. During the maintenance and use of the battery, it usually takes Measure the two parameters of electrolyte temperature and density. Therefore, in the process of operation, it forms an obstacle to the convenience of operation. We need to consider how to improve the safety, convenience and practicability of the use and maintenance of traction lead-acid batteries.
