Description
Technical field:
This utility model belongs to electric automobile security fields, automatic particularly to a kind of electric automobile battery box
Extinguishing device.
Background technology:
Due to reasons such as production technologies, it is poor that the capacity of each cell and performance are inevitably present some
Different, if things go on like this, this species diversity can be increasing, and the utilization rate of set of cells is the most worse and worse.More serious
, in the environment of overcharging or excessively putting, the barrier film between battery positive/negative plate can be breakdown and short-circuit, produces
Raw high temperature, overheated make electrolyte vaporization, expand and make battery case rupture, even catch fire or explode.
Therefore, it is necessary for arranging extinguishing device on electric automobile.
Typically on electric automobile, all can be equipped with hand fire extinguisher, but, hand fire extinguisher extinguishing chemical
Measure less, and implement fire extinguishing and can exist temporal delayed, it is impossible to enough control the condition of a fire effectively and timely,
Battery case can only be look at helplessly burn away and even explode.
The information being disclosed in this background section is merely intended to increase general background of the present utility model
Understand, and be not construed as recognizing or imply in any form that this information structure is for the general skill in this area
Prior art well known to art personnel.
Utility model content:
The purpose of this utility model is to provide a kind of electric automobile battery box automatic fire extinguisher, thus gram
Take above-mentioned defect of the prior art.
For achieving the above object, this utility model provides
Electric automobile battery box automatic fire extinguisher, including: air pump, high pressure tank, high pressure fluid reservoir,
Battery case；Described air pump, high pressure tank, high pressure fluid reservoir, battery case pass sequentially through pipeline and connect,
It is provided with check valve on connection pipeline between described air pump and high pressure tank, described high pressure fluid reservoir sets
It is equipped with miniature relief valve；It is provided with battery box cover on described battery case, described battery box cover is provided with bar
Shape sheet metal suspension, is provided with cavity, has been evenly arranged extinguishing chemical in described cavity in described battery box cover
Connection pipeline outside pipeline, described extinguishing chemical pipeline and battery case connects, and described extinguishing chemical pipeline is fixed on
On bullion sheet suspension；Described bullion sheet suspension is that " well " font structure is by battery box cover decile
Being nine pieces, described extinguishing chemical pipeline is provided with the spy fire tube extended downward vertically every piece of center.
Compared with prior art, this utility model has the advantages that
Quickly the position caught fire can be implemented precise fire extinguishing, extinguishing action implements the response time the most faster,
Foamite amount is less.It is set using reliable, installs and change spy fire tube more convenient.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model electric automobile battery box automatic fire extinguisher；
Reference is: 1-air pump, 2-high pressure tank, 3-high pressure fluid reservoir, 4-battery case are blue, 5-is mono-
To valve, the miniature relief valve of 6-, 7-battery box cover, 8-cavity, 9-bullion sheet suspension, 10-visit fire tube,
11-controller.
Detailed description of the invention:
Below detailed description of the invention of the present utility model is described in detail, it is to be understood that this practicality is new
The protection domain of type is not limited by detailed description of the invention.
