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
At present, in the modern production field of circulation, widely, the advantages such as 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 in electric motor car application.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 in electric motor car, need a lot of cells to be installed in multiple battery case, form by series and parallel the requirement that battery pack reaches car power source.But due to reasons such as production technologies, inevitably there are some differences in the capacity of each cell and performance, electric motor car operationally, the battery of the little poor performance of capacity had puts phenomenon, and when charging, the battery of the little poor performance of capacity there will be again and overcharges phenomenon, 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, under overcharging or crossing the environment put, the barrier film between battery positive/negative plate can breakdown and short circuit, produces high temperature, overheated electrolyte is vaporized, expansion and battery case is broken, and even catches fire or explodes.
In order to prevent above-mentioned problem, common electric motor car all can be equipped with hand fire extinguisher, but, general hand fire extinguisher fire-fighting dose is less, and from find when electric motor car burst smolder, catching fire can delayed life period to implementing fire extinguishing, substantially not having great effect to effectively implementing battery of electric vehicle fire extinguishing, once catch fire, battery case can only be look at helplessly and burn away and even explode.
Summary of the invention
The present invention is to overcome the deficiencies in the prior art, provide a kind of can the battery case extinguishing device of self-extinguishing, when battery case catches fire, can automatically extinguish the blaze rapidly in time.
To achieve these goals, the present invention is by the following technical solutions: a kind of battery case extinguishing device, the battery box cover comprising the battery case for installing battery pack and can mate with battery case, battery box cover is provided with cavity, in cavity, be furnished with spy fire tube, visit fire tube and be connected with the extinguishing chemical storage bottle outside battery box cover.Battery box cover is provided with cavity, is arranged in cavity by spy fire tube, be to dismantle spy fire tube when changing battery, simultaneously basic guarantee original physical dimension of battery case.Arrange in cavity and visit fire tube, visit fire tube and be connected with the extinguishing chemical storage bottle outside battery box cover, in extinguishing chemical storage bottle, extinguishing chemical is housed.Use the battery case extinguishing device visiting fire tube, do not need power supply and traditional fire alarming and controlling parts, thus reduce costs and installation difficulty, also substantially increase the reliability of extinguishing device, avoid the misoperation of automatically controlled warning piece.Tradition fixed fire extinguishing system only carries out detection to integral protection space, no matter the size of fire implements fire extinguishing to whole space, thus causes detector response time slow, the situation that extinguishing chemical is wasted in a large number.Flexible spy fire tube can be arranged in cavity easily, visit fire tube to be connected with the extinguishing chemical storage bottle outside battery box cover, extinguishing chemical is filled with in pipe, visit fire tube when producing burning things which may cause a fire disaster in battery case and will be subject to thermal fracture, discharge extinguishing chemical fire extinguishing immediately, with prestissimo, point-to-point fire extinguishing is implemented to the position only caught fire, thus the corresponding time is faster, fire extinguishing consumption is more economized, and it is at raising fire-fighting efficiency, and cost-saving and environmental protection aspect is the fire-fighting mode of science more in current fixed equipments for fire protection.
