The connection of body detection device.
Shut-off valve 9 and pump 10 are additionally provided on above-mentioned gas signal piping.In general, above-mentioned shut-off valve is mounted on gas
Between detection device and the gas outlet of chamber, the pump is mounted between gas detection apparatus and shut-off valve.Utilize shut-off valve
Guarantee that gas flow direction can only be flowed from a direction, the gas suck-back overheated in chamber is effectively prevent to enter gas detecting tube
Lu Zhong.The invention combines a variety of fire extinguishing forms, can both cool down, drop oxygen concentration, increases inert atmosphere, and can benefit
Chain reaction is blocked with medicament, prevents fire behavior from occurring or spreading.
In an alternative embodiment, condenser 11, the condenser installation are additionally provided on above-mentioned gas signal piping
It, can be by the gas cooling acquired out of chamber to detection device using condenser between shut-off valve and the gas outlet of chamber
In the tolerance interval of each component (sensor).It should be noted that the combustible gas physical examination being arranged in gas detection pipeline
Survey sensor, Smoke Detection sensor all have the scope of application of certain temperature, if beyond the temperature under its normal use operating condition
Degree, then will affect the accuracy of detection data, even result in sensor degradation.
Therefore, it is necessary to be reduced the gas temperature being introduced into gas detection pipeline using condenser, passed using corresponding
The fuel gas or smog whether generated with battery catches fire in sensor detection gas, and then accurate judgement fire behavior.Certainly, having
When body is implemented, one temperature sensor can be set for condenser to control the work temperature of condenser in gas detection pipeline
Degree, guarantee is controllable by the cooling gas temperature to be detected of condenser, these belong to prior art scope, and details are not described herein.
Above-mentioned gas detection device has included at least fuel gas detection sensor, the Smoke Detection connecting with control unit
Sensor and temperature detection sensor.In general, fuel gas detection sensor, Smoke Detection sensor are arranged in gas detection
In pipeline, and temperature detection sensor is arranged in chamber, and each sensor is connect with control unit, sensor signal feedback
After control unit, issued in electromagnetism valve events or control water injector in signal control chemical spraying device by control unit
It is pressurized pump startup.

When signal, usually control is pressurized pump startup, and pressure increases in water supply pipe, and certainly, those skilled in the art are using other existing
Water is delivered at spray head as long as realizing by water supply pipe by some technological means, by spray head water spray, and then is realized
To power battery position sprinkling fire.
When above-mentioned measure can not still prevent power battery on fire, then chamber can be detected by temperature detection sensor
(because after on fire, the temperature that open fire generates commonly reaches several Baidu to interior temperature anomaly, with common temperature anomaly and smoke conditions
Under temperature have it is significantly different), then can feed back to the corresponding temperature information of control unit, control unit sends control signal, opens
Dynamic booster pump, carries out sprinkling fire.
A kind of anti-prosecutor of fire using above-mentioned active power battery testing case fire disaster intelligently prevention and control system is provided below
Method, particularly, by gaseous state in gas detection apparatus real-time detection chamber,
When detecting that chamber internally-powered battery uncontrollable temperature rise occurs or has flue gas generation, thermal runaway suppression is fed back to
Device signal processed inhibits device injection to inhibit medicament by thermal runaway；
When gas detection apparatus, which detects, has open fire in chamber, then fire attack device signal is fed back to, by fire
Fighting device sprinkling fire.
The power battery chamber fire disaster intelligently prevention and control system that the invention provides can by two-stage early warning and prevention and treatment
The disaster accidents such as burning, the explosion for effectively high-low temperature test chamber internally-powered battery being inhibited to occur, it is rapid to sudden instability, it mentions
The safety that high electrokinetic cell equipment uses.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
