Abstract

The invention relates to a lead-acid storage battery and provides a durable anti-inclination acid-proofing explosive-proof electrolyte-rich starting lead-acid storage battery. When an inclination angle of an electrolyte-rich starting lead-acid storage battery exceeds a certain angle and the level of an electrolyte solution inside the battery exceeds an injection hole edge, the electrolyte solution is leaked and the leaked electrolyte solution can cause vehicle corrosion and potential safety hazards. The durable anti-inclination acid-proofing explosive-proof electrolyte-rich starting lead-acid storage battery is characterized in that an anti-overflow assembly is arranged on an injection hole and comprises an anti-overflow pipe, an explosive-proof acid filtering disc at the upper part of the anti-overflow pipe, a small ventilating cover above the explosive-proof acid filtering disc and a sealing gasket at the lower part of the anti-overflow pipe, a vent hole is formed in the middle part of the small ventilating cover, the inner cavity of the anti-overflow pipe forms a liquid containing cavity, a connecting part is arranged at the lower part of the anti-overflow pipe and is connected with the injection hole of an upper cover, and the sealing gasket is located between the anti-overflow pipe and the upper cover. According to the technical scheme, the problem of leakage of the electrolyte-rich starting lead-acid storage battery is solved, potential safety hazards are eliminated, the battery capacity is greatly improved and the battery life is greatly prolonged.

Description

Technical field

[0001] The invention relates to a lead-acid battery. Background technique

[0002] The flooded start-up lead-acid battery is widely used in special engineering vehicles, such as excavators for long-term tilting operations when used, and long-term tilting operations for quarrying vehicles in mountainous areas. The flooded-start lead-acid battery has flowing electrolyte inside, which has certain requirements for battery installation and tilting position. When the battery exceeds a certain angle, the internal electrolyte level exceeds the edge of the injection hole, and leakage will occur. The leakage of electrolyte will not only It will corrode the vehicle and cause safety hazards; due to the loss of electrolyte, the battery life and capacity are greatly shortened; at the same time, acid mist escapes from the battery during the charging process, and it will explode in case of open fire.
