Description
Technical field：
The present invention relates to power battery technology field, and in particular to a kind of power battery box fire extinguishing system.
Background technology：
With the development of New Energy Industry, the new energy vehicles such as increasing electrocar, electric bus are pushed away
To market.But gradually it is exposed the problem of following, still can not the problems such as the blast of new energy car battery system, spontaneous combustion
Obtain basic solution.
Battery system hinders for some reason, collides and causes internal short-circuit, or in high temperature environments and in charge and discharge process, battery bag meeting
Short time gathers many heats, in the case where battery heat removal system can not exclude amount of heat in time, may result in battery
System temperature is quickly raised, and is ultimately resulted in battery system burning or even is exploded.
In the application of existing electrokinetic cell system, optimize just for battery bag heat dispersion, pole can not be solved
The problem of occurring in the case of end.Once battery system breaks down or collided, cause internal short-circuit, battery system will
There is the risk of burning and blast.
The content of the invention：
The present invention devises a set of automatic fire extinguishing system for electrokinetic cell system, and whole system is independently of battery system
Automatic fire extinguishing system in addition, the system monitors battery bag internal environment in real time, once it is too high to monitor battery bag internal temperature
Or there is spark, smog, just automatic alarm and connect outside fire-fighting system battery bag is put out a fire, can effectively reduce battery bag
Burning, the risk of blast.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of power battery box fire extinguishing system, it is characterised in that：Including Battery case, battery box cover, controller, temperature-sensitive
Line, output line and fire nozzle, described battery box cover are arranged on the upside of Battery case, and described controller, which is fixed, to be set
Put on Battery case, described temp.-sensing wire is arranged on Battery case inwall, temp.-sensing wire is connected to controller input, described
Output line be connected to controller output end, the other end of output line is connected to battery case by Battery case interface
On fire-fighting equipment outside body, described fire nozzle is arranged on Battery case, and described fire-fighting equipment output pipe is through disappearing
Inside anti-nozzle UNICOM Battery case.
Explosion-proof vent valve is provided with described Battery case.
The upside of described Battery case and the junction of battery box cover are provided with a circle sealing gasket.
Described temp.-sensing wire is arranged in Battery case inwall surrounding by the upper position.
Multiple sensors are provided with described temp.-sensing wire.
Action process：Temp.-sensing wire line internal sensor collects the information such as Battery case inside spark, smog, controls at once
Device starts alarm and synchronous signal output line outputs signal to outside fire-fighting equipment, and outside fire-fighting equipment is started working and will fire extinguishing
Medium is sprayed to inside Battery case through nozzle, so as to realize fire-extinguishing function concurrently.At the same time, because the sealed pad of Battery case is completely close
Envelope, Battery case internal pressure rise, explosion-proof valve is started working, and is depressured to Battery case external exhaust gas, to balance inside and outside air pressure, is prevented
Only Battery case internal pressure is too high explodes.
Existing electrokinetic cell system, which only has preventive measure, prevents battery case internal short-circuit, temperature by battery management system
The functions such as high alarm are spent, once but battery management system breaks down or battery system is damaged through external force collision, electricity
Pond management system can not close major loop in time, and battery system is likely to occur fire or even exploded.The present invention not only may be used
To play early stage fire prevention function, it can also be carried out actively to having occurred fire or the battery system under thermal runaway state
Fire extinguishing.
The beneficial effects of the invention are as follows：The present invention can not only play early stage fire prevention function, can also be to having occurred
Fire or battery system under thermal runaway state carry out active suppression, reliability and safe.
Brief description of the drawings：
Fig. 1 is schematic structural view of the invention.
Embodiment：
In order that technological means, creation new feature, reached purpose and effect that the present invention is realized are easy to understand, below
With reference to being specifically illustrating, the present invention is expanded on further.
As shown in figure 1, a kind of power battery box fire extinguishing system, including Battery case 3, battery box cover 1, controller 5, temperature-sensitive
Line 4, output line 6 and fire nozzle 7, battery box cover 1 are arranged on the upside of Battery case 3, and controller 5 is fixedly installed on electricity
On pond casing 3, temp.-sensing wire 4 is arranged on the inwall of Battery case 3, and temp.-sensing wire 4 is connected to the input of controller 5, output line 6
The output end of controller 5 is connected to, the other end of output line 6 is connected to outside Battery case 3 by the interface of Battery case 3
On fire-fighting equipment, fire nozzle is arranged on Battery case 3, and fire-fighting equipment output pipe is through the UNICOM's Battery case 3 of fire nozzle 7
It is internal.Explosion-proof vent valve 2 is provided with Battery case 3.The upside of Battery case 3 is provided with one with the junction of battery box cover 1
Enclose sealing gasket 8.Temp.-sensing wire 4 is arranged in the inwall surrounding of Battery case 3 by the upper position.Multiple sensors are provided with temp.-sensing wire 4.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
