Problems solved by technology

[0004] Lithium batteries used in firefighting equipment in the prior art have high requirements for explosion-proof, and the batteries need good high-temperature resistance, and at the same time, the batteries need to be kept in good condition. After charging and discharging for a long time, it is easy to cause battery cells to bulge. Regular maintenance is required after use. However, during maintenance, it is necessary to disassemble the shell to observe the working status of the battery cells, and to observe whether there is leakage and fire hazards, which is time-consuming and laborious.

Abstract

The invention belongs to the technical field of lithium batteries, and particularly relates to a fireproof and explosion-proof lithium battery device applied to fire fighting equipment, which comprises a shell, a top cover and a battery cell, a group of battery cells are uniformly distributed in the shell; an isolating ring is connected between the adjacent battery cells, a first contact and a second contact are arranged in the isolating ring, and the first contact and the second contact are respectively connected with the side wall of the battery cell on the corresponding side; the second contact is connected with the positive electrode of the battery cell through a wire, and the first contact is connected with the negative electrode of the battery cell in series through a first wire, a buzzer and a second wire. The first contact and the second contact are driven to make contact and the buzzer is triggered to give an alarm sound when the battery cell is seriously swelled, so that the overhaul times of the shell are reduced, meanwhile, the maintenance timeliness of the battery is improved, the normal working state of the battery is ensured, and the safety of the battery in the using process is ensured.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a fire-proof and explosion-proof lithium battery device applied to fire-fighting equipment. Background technique [0002] There are lithium batteries installed in some firefighting equipment, but due to the rescue needs of firefighting work, the temperature of the rescued fire scene is very high, and it may come into contact with the fire source, and the lithium battery is used in the high temperature environment of the fire. It is prone to combustion and explosion, which brings great difficulties to fire fighting and rescue and on-site disposal, which is not conducive to the safe development of fire protection work. [0003] A Chinese patent with the publication number CN209786035U discloses a fire-proof and explosion-proof lithium battery device used in fire-fighting equipment, including an upper cover, an outer shell and a lithium battery pack. The upper end of the o...
