Description
Technical field
The present invention relates to a kind of extinguishing device, especially relate to a kind of battery case extinguishing device.
Background technology
The advantages such as at present, in the modern production field of circulation, it is very extensive that electric motor car is used, and lithium ion battery has that specific capacity is large, operating voltage is high, has extended cycle life, volume is little, lightweight have become the first-selection of electric motor car.Electrokinetic cell as electric vehicle power sources requires to have larger capacity and voltage, and the voltage of the lithium ion battery of monomer and capacity are all very little, therefore, generally need a lot of cells is installed in a plurality of battery cases in electric motor car, form the requirement that battery pack reaches car power source by series and parallel.But owing to reasons such as production technologies, there are some differences inevitably in the capacity of each cell and performance, electric motor car is when operation, the battery of the little poor performance of capacity had puts phenomenon, and when charging, phenomenon can appear overcharging again in the battery of the little poor performance of capacity, if things go on like this, this species diversity will inevitably be increasing, makes the utilization rate of battery pack worse and worse.More seriously, overcharging or crossing under the environment put, the barrier film between battery positive/negative plate can be breakdown and short circuit, produces high temperature, overheatedly makes the electrolyte vaporization, expands and battery case is broken, even catch fire or explode.
In order to prevent above-mentioned problem, all can be equipped with hand fire extinguisher in the common electric motor car, but, general hand fire extinguisher fire-fighting dose is less, and from finding that working as the electric motor car burst smolders, catches fire to the hysteresis of implementing on the fire extinguishing meeting life period, fire extinguishing does not have great effect substantially to effective enforcement battery of electric vehicle, in case catch fire, can only see helplessly that battery case burns away even explodes.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, and a kind of battery case extinguishing device that can self-extinguishing is provided, and when battery case catches fire, can automatically in time extinguish the blaze rapidly.
To achieve these goals, the present invention is by the following technical solutions: a kind of battery case extinguishing device, comprise for the battery case that battery pack is installed and can with the battery box cover of battery case coupling, battery box cover is provided with cavity, in cavity, be furnished with the spy fire tube, visit fire tube and link to each other with battery box cover extinguishing chemical storage bottle outward.Being provided with cavity at battery box cover, will visiting fire tube and be arranged in the cavity, is in order to dismantle the spy fire tube when changing battery, simultaneously basic guarantee original physical dimension of battery case.Arrange in the cavity and visit fire tube, visit the outer extinguishing chemical storage bottle of fire tube and battery box cover and link to each other, in the extinguishing chemical storage bottle, extinguishing chemical is housed.Use the battery case extinguishing device of visiting fire tube, do not need power supply and traditional fire alarm control assembly, thereby reduce cost and installation difficulty, also greatly improved the reliability of extinguishing device, avoided the misoperation of automatically controlled warning piece.The tradition fixed fire extinguishing system only carries out detection to the integral protection space, no matter the size of fire is implemented fire extinguishing to whole space, thereby causes detector response time slow, the situation of a large amount of wastes of extinguishing chemical.Flexible spy fire tube can be arranged in the cavity easily, visiting fire tube links to each other with battery box cover extinguishing chemical storage bottle outward, be full of extinguishing chemical in the pipe, when producing burning things which may cause a fire disaster in the battery case, visit fire tube and will be subjected to thermal fracture, discharge immediately the extinguishing chemical fire extinguishing, with prestissimo point-to-point fire extinguishing is implemented at the position that only catches fire, thereby the corresponding time is faster, the fire extinguishing consumption is more economized, and it is improving fire-fighting efficiency, saves cost and environmental protection aspect and be in the present fixed equipments for fire protection the more fire-fighting mode of science.
