Enhanced liquid-rich battery with seal battery cover

Abstract

The invention discloses an enhanced liquid-rich battery with a seal battery cover, which belongs to the technical field of batteries. The battery comprises a casing body. A casing cover is arranged onthe top of the casing body. A matched acid injection cap is arranged on the inner wall of an acid injection hole. The acid injection cap includes a fixed plate connected with a boss. A plug is connected with the bottom of the fixed plate. The bottoms of positive and negative poles are connected with positive and negative terminals of a battery pole plate which is arranged in the inner cavity of the casing body respectively. According to the device, the matched acid injection cap is arranged on the inner wall of the acid injection hole, which effectively improves the sealing of the acid injection hole; the acid injection cap is provided with the fixed plate connected with the boss, which effectively improves the fixedness of the acid injection cap and prevent the leakage of the internal electrolyte of the battery caused by the fall of the acid injection cap; the outer walls of the poles are sleeved by gaskets and pressure rings; the gaps between the poles and the pressure rings are filled with sealants, which effectively improves the fixing effect of the poles; and furthermore, the sealing effect of the poles and pole holes is improved through the filling of the sealants.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to an enhanced flooded storage battery with a sealed battery cover. Background technique [0002] Flooded battery means that the remaining space in the battery tank except the base plate, separator and other solid assembly parts is completely filled with sulfuric acid electrolyte, and the electrolyte is in a state of surplus and excess. The drum is called a "flooded" battery. However, the sealing effect of the flooded battery is poor when processing the shell of the flooded battery, and the sulfuric acid electrolyte in the flooded battery often leaks through the acid injection hole, resulting in a flooded battery. Damage to other structures on the surface of the battery will shorten the service life of the flooded battery. For this reason, we propose an enhanced flooded battery with a sealed battery cover.
