Automatic fire extinguishing electric box

Technical Field

The utility model relates to a lithium cell safety field indicates an automatic electronic box of putting out a fire very much.

Background

With the popularization and application of new energy sources such as solar energy, wind energy and the like, an energy storage technology develops, and lithium batteries gradually become mainstream products for energy storage because of the advantages of higher energy, long service life, high rated voltage, high power bearing capacity, very low self-discharge rate, light weight, environmental protection, basically no water consumption in production and the like.

The lithium cell can produce a large amount of heats at the in-process of charge-discharge for lithium cell temperature rises, when lithium cell ambient temperature is higher than 60 ℃, can make the inside chemical reaction of lithium cell accelerate, shortens the life-span of lithium cell, and there is safety problems such as fire, explosion, consequently need be equipped with the fire control facility for the electronic box of placing the lithium cell with the needs of preparing for from time to time.

For fire extinguishing of an electric box, the following method is conventionally adopted: the method comprises the following steps that 1, a fire extinguisher is placed in an electric box, alarm facilities such as a temperature sensor and an alarm bell are arranged, when a lithium battery is detected to be ignited, an alarm is given out, and a worker receives the alarm and then extinguishes the fire by using the fire extinguisher in the electric box; and 2, arranging a plurality of fire-fighting spray headers on the top of the electric box, arranging a plurality of temperature sensors, and controlling all the fire-fighting spray headers to spray extinguishing agent to extinguish fire when the temperature sensors detect that fire is possibly generated due to overhigh temperature, namely, uniformly spraying and extinguishing the fire.

However, the conventional method has the following disadvantages: the method 1 has the defect that the fire cannot be extinguished in time, a certain potential safety hazard exists when workers enter the electric box to extinguish the fire, and when the sensitivity of the temperature sensor is reduced, the optimal fire extinguishing opportunity is delayed; the method 2 has the defects of uniform spraying fire extinguishing, low fire extinguishing speed without focusing on a fire area, large dosage of required fire extinguishing agent, high fire extinguishing cost, great damage to a non-fired lithium battery in the electric box, and delay of the optimal fire extinguishing time when the sensitivity of the temperature sensor is reduced.

Therefore, how to provide an automatic fire extinguishing electronic box, realize promoting the promptness and the security of putting out a fire, reduce the cost of putting out a fire and to the harm of lithium cell, become a problem that awaits the solution urgently.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing an automatic electronic box of putting out a fire, realizes promoting the promptness and the security of putting out a fire, reduces the cost of putting out a fire and to the harm of lithium cell.

The utility model discloses a realize like this: an automatic fire extinguishing electric box comprises a box body, at least one fire fighting pipe made of low-melting-point materials, at least one pump, a plurality of temperature sensors and an industrial personal computer;

the fire fighting pipe is arranged at the upper end inside the box body and is positioned right above the battery cell explosion-proof valve of each lithium battery; the pump is communicated with the fire fighting pipe; the temperature sensor is arranged in the box body; the pump and the temperature sensor are respectively and electrically connected with the industrial personal computer.

Furthermore, a box door and an observation window are arranged on the side wall of the box body.

The utility model has the advantages that:

through setting up the low melting point material fire control pipe and pump, the inside storage of fire control pipe has the fire extinguishing agent, the pump provides pressure for the fire control inside, and after the electric core explosion-proof valve of certain lithium cell catches fire, can melt immediately the position that the fire control pipe corresponds, the fire extinguishing agent is in automatic blowout under the pump action aims at the electric core explosion-proof valve that catches fire and puts out a fire, works as the industrial computer detects the inside temperature maintenance of electronic box through temperature sensor and after long the time that normal temperature predetermines, closes the pump stops to spout the fire extinguishing agent, gets into for the staff in the tradition the inside fire extinguisher that puts out a fire with the box puts out a fire, perhaps puts out a fire with fire sprinkler unification, very big promotion the promptness and the security of putting out a fire, because the fixed point is put out a fire.
