A storage battery can monitor the explosion-proof device

Abstract

The invention provides an anti-explosion device capable of monitoring a storage battery. The anti-explosion device comprises a valve body; a plunger is arranged inside the valve body; a wedged lug boss I and a wedged lug boss II are respectively arranged on the columnar faces on the both sides of the plunger; the end face of the wedged lug boss I and the end face of the wedged lug boss II are respectively in contact with the columnar faces on the both sides of the plunger; a wedged block I is arranged on the outer side of the wedged lug boss I; a wedged block II is arranged on the outer side of the wedged lug boss II; a spring I is arranged on one side of the wedged block I; a spring II is arranged on one side of the wedged block II; and the end parts of the springs I and II are fixed on the inner wall of the valve body. The anti-explosion device provided by the invention is simple, reliable, safe and practical, and can effectively control the internal pressure of the storage battery so as to prevent the explosion of the storage battery due to that the internal pressure of the storage battery is too high and improve the anti-explosion property of the battery. The anti-explosion device can prevent a cover plate of the anti-explosion battery from being damaged, is beneficial to material saving, and can improve the practical property of the battery. With the adoption of the anti-explosion device, a leakage state of the storage battery can be monitored in real time, and can be treated in time, so that the security property of the storage battery is high.

Description

technical field [0001] The invention relates to an explosion-proof device for a storage battery, in particular to a monitorable explosion-proof device for a storage battery. Background technique [0002] Due to its low cost, stable performance, and convenient use, batteries are widely used in daily and industrial fields. During the use of the battery, gas is often generated inside, causing the internal pressure of the battery to rise continuously, and the battery is very likely to explode. In many hazardous environments, a battery explosion can have extremely serious consequences. Therefore, the explosion-proof performance of the battery is a very important performance index. [0003] In the current battery explosion-proof technology, the most common is to use the battery explosion-proof cover plate. The battery explosion-proof cover plate is processed with a weak part. When the pressure inside the battery rises and exceeds the pressure value that the weak part can withsta...

Problems solved by technology

This method simply and effectively improves the explosion-proof performance of the battery, but this is a self-destructive explosion-proof method, that is, an explosion-proof cover can only be used once and cannot be recycled, and the scrap rate is high, resulting in waste of materials and inconvenience
