A kind of structural schematic diagram of embodiment.
Wherein, there is container 1 container value 12, driving device 6 to be interconnected and fix with container value 12 at gas outlet 11, when
After driving device 6 is triggered, the blowout disk in meeting bursting container value 12 keeps the extinguishing chemical in container 1 spouting.Driving dress
6 are set to be controlled by control module 4.
Fig. 6 is a kind of partial structurtes signal of embodiment of a kind of lithium battery box fire alarm of the present invention and protective device
Figure.
Such as Fig. 6, two containers 1 are depressurized by decompressor 32 first after being opened, then mixing/priority injection
Header 3, at this point, the extinguishing chemical with mixing/priority injection in header 3, and 33 feedback response of signal feedback device, it prompts
People positioned at the observation end of distal end, this lithium battery box fire alarm and protective device have been started to work, finally in selector valve
Under effect, some or multiple outlet sides 31 are opened, realization is put out a fire for corresponding lithium battery box.
Mode is preferably matched as two containers, one of container 1 can be heptafluoro-propane container 1, can reach
The maximum pressure arrived is 5.3Mpa, primarily serves the effect stamped out the flames；Another container 1 can be CO 2 vessels 1,
The attainable maximum pressure of institute is 15Mpa, and main function is cooled down to comburant, improves the fire extinguishing of heptafluoro-propane extinguishing chemical
Effect, and after stamping out the flames, realize effective temperature-reducing, prevent resume combustion；In order to can be more preferable by the container of two kinds of different pressures
Collaborative work, under the action of decompressor 32, heptafluoro-propane extinguishing chemical is mixed with carbon dioxide extinguishing agent/successively inject
In header 3, while decompression forms the extinguishing chemical for mixing/priority injection that outlet pressure is 2Mpa, and mixing/priority injection is gone out
Fiery agent can at this pressure persistently spray comburant, maintain the duration and stability of injection, improve fire extinguishing
Effect；Therefore, two kinds of extinguishing chemicals can be stored independently in storage, avoid causing pressure inside the tank unstable due to loading in mixture, finally
Influence jeting effect, and two kinds of extinguishing chemicals when in use can effective supplement, improve extinguishing effect, reduce resume combustion possibility.
And in use, when 32 failure of decompressor, pressure is likely to bear energy beyond header 3
Power, cause header 3 burst, then reach header 3 bear pressure before, safety valve 34 can reach early warning valve first
Value releases the extinguishing chemical of mixing/priority injection, if the pressure of bearing of header 3 is 3.5Mpa, the early warning valve of safety valve 34
Value thief bears pressure such as 3.4Mpa less than header 3.
When gas leakage occurs for container 1, signal feedback device 33 monitors the pressure of header 3 in real time, if control module 4 at this time
Triggering container opens fire extinguishing, then observation end can the timely processing failure.
Observation end may be used by the charactron that is connected with control module 4 either LED module or acoustic alarm module come
It realizes.
