Convenient for drainage flow, 1 side outer wall of cabinet is welded with bracket 12, and is connected separately with water purifier in bracket 12 and 1 upper end of cabinet
13 with water pipe 14, be connected with spray head 15 on water pipe 14, quantity is arranged according to depending on 14 specification of water pipe in spray head 15, water purifier
Level-one recovery tube 16 and secondary recovery pipe 17 are connected separately between 13 and sink 6 and water pipe 14,1 upper end of cabinet is respectively equipped with
Water inlet pipe 20, injector 21 and loader 22, and water inlet pipe 20 is connected with water pipe 14, injector 21 is connected with loader 22
It connects, and is communicated with driving tube 23 between injector 21 and water inlet pipe 20.
Further, it is mounted on check valve on level-one recovery tube 16 and secondary recovery pipe 17, to avoid in water pipe 14
Water body flow in water purifier 13 and sink 6.
Sliding slot 2 is the cyclic structure of head and the tail connection, and 3 sliding sleeve of sliding rail is set in sliding slot 2, can be in the band of driving equipment 4
Under movement is used, so that dry-ice fire extinguisher 5 moves back and forth in cabinet 1, in order to cool down operation, water to each position
Slot 6 is groove-like structure of the upper end without sealing, and filter plate 7 and sink 6 are located at immediately below floor 10, after to preliminary purification
Water body carries out unified collection.
It is separately installed with level-one sucking pump 18 and second level sucking pump 19 on level-one recovery tube 16 and secondary recovery pipe 17, to recycling
Water source carry out transport recycling.
Water inlet pipe 20 extends to outside cabinet 1 far from one end connection of water pipe 14, and sodium bicarbonate is filled in loader 22
Level-one valve 24 and second level valve 25 are separately installed on medium, water inlet pipe 20 and driving tube 23.
The reaction it should be noted that ammonium hydrogen carbonate particle must can just decompose under 50 degrees Celsius and conditions above,
And there is the lithium ion battery self-temperature of fire threat usually more than this temperature standard, timely lithium ion battery is at the beginning of dry ice
Absorbing and cooling temperature is walked, but still not can ensure that the internal temperature of lithium ion battery is lower than under the temperature of thermal runaway, so in order to avoid
The generation herein of thermal runaway needs sodium bicarbonate medium to test to it and heat-absorbing action.
Further illustrate, in 1 upper end of cabinet can many places install thermal imaging camera, in order to in cabinet 1 carry out heat
Induction monitoring.
The present invention can illustrate its principle of work and power by following mode of operation:
When fire danger occurs, it is necessary in first time internal cutting off power supply.
The first step, at thermal runaway initial stage, that is, being mounted in the container body 1 of lithium ion battery has high temperature but the flames of anger
It threatens, carries out fire-fighting maintenance using dry ice fire-fighting mode: opening driving equipment 4, driving equipment 4 keeps sliding rail 3 sliding on sliding slot 2
It is dynamic, and dry-ice fire extinguisher 5 is driven to move in cabinet 1, injection dry ice is carried out with the lithium ion battery to high temperature.Liquid in fire extinguisher
State carbon dioxide gasifies after spraying to absorb heat, a large amount of heats absorbed on lithium ion batteries, has certain cooling work to lithium ion battery
With, and since carbon dioxide density is greater than air, carbon dioxide itself does not support the inert gas of burning, so carbon dioxide exists
Lower section is covered on comburant surface, and the middle oxygen for playing the role of completely cutting off air forms protective layer.
Step 2: after carrying out cooling operation using dry-ice fire extinguisher 5 because inside lithium ion cell structure may not by
To dry ice cooling influence so that lithium ion battery itself still have certain thermal temperature, the temperature even 50 DEG C with
On, it is most likely that initiation temperature gos up again, induces the generation of open fire, so needing further cooling.
In the case where level-one valve 24 is closed second level valve 25 and opened, make the water body entered from water inlet pipe 20 through driving tube 23
Into in injector 21, so that injector 21 obtains power, to be conveyed to the sodium bicarbonate particle medium in loader 22,
Sodium bicarbonate is attached on the lithium ion battery for still having higher waste heat.Sodium bicarbonate particle under 50 DEG C of environment, by
Gradually resolve into sodium carbonate, water and carbon dioxide.Water body flow can further absorb heat to lithium ion battery, with reduce lithium from
The temperature of sub- battery, meanwhile, carbon dioxide sinks, and to completely cut off to oxygen needed for burning, reduces the possibility that open fire generates
Property.
Step 3: then needing a large amount of water to put out a fire when lithium ion battery generates biggish open fire.In second level valve
Close level-one valve opening in the case where, enter the water body in water inlet pipe 20 in water pipe 14, and by spray head 15 to lithium from
Sub- battery is sprayed.
In the process, after water body is flow on floor 10, filter plate 7 is flowed to by water seepage hole 11, is entered after primary filtration
Sink 6 carries out unified collection.Level-one sucking pump 18 is opened, and the sewage in sink 6 is flowed in water purifier 13 through level-one recovery tube 16,
It is then turned on second level sucking pump 19, enters purified clean water source in water pipe 14 through secondary recovery pipe 17 again, finally through spray head
15 spray, and reciprocation cycle can not only reduce the waste of water resource by recycling, to meet fire-fighting demand, also can avoid water
Source pollution.
It should be noted that because contain a large amount of electrolyte in lithium ion battery, and contain carbonic acid diformazan in electrolyte
The content of ester, dimethyl carbonate is higher, shows that a possibility that causing fire is bigger, and when fire occurs, electrolyte can also occur
Leakage.So water body can not only put out open fire when being put out a fire using a large amount of water source to lithium ion battery,
Absorbing and cooling temperature can be carried out to lithium ion battery, avoid thermal runaway repeatedly, it is often more important that, water source can be to the carbon in electrolyte
Dimethyl phthalate is diluted, and the content concn of dimethyl carbonate is reduced, to reduce the possibility for inducing open fire re-ignition
Property.
When determining that the flames of anger threatens in container, using thermal imaging camera to the lithium ion battery in container and respectively
Electronic component carries out thermoinduction shooting, with whether there is also thermal runaway threats in check and evaluation cabinet 1；Finally, in insulating tool
Protection under, it can be achieved that artificial detection confirm.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
