It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a schematic structural diagram of an automatic fire extinguishing device for battery storage according to an embodiment of the present invention, which is applicable to a situation where thermal runaway occurs in a battery storage area of a plurality of battery packs and rapid fire extinguishing and temperature reduction are required, and the method may be executed by the automatic fire extinguishing device for battery storage, and specifically includes the following steps:

as shown in fig. 1, a battery storage automatic fire extinguishing apparatus 1 includes: a battery storage area 10, a battery pack 20, an infrared temperature sensor 30 (not shown in the figure), a fire extinguishing agent storage module 40, a data transmission module 50, a control module 60, and an isolation device 70;

the control module 60 is configured to transmit the internal temperature information and the environmental temperature information to the data processing platform through the data transmission module 50, receive alarm data sent by the data processing platform, and send an isolation instruction according to the alarm data;

the isolation device 70 is connected to the control module 60, and configured to isolate a target battery pack region corresponding to the alarm data according to an isolation instruction of the control module 60, lock the target battery pack region, and return an isolation completion signal to the control module 60;

the fire extinguishing agent storage module 40 is configured to release a fire extinguishing agent to the target battery pack area according to a fire extinguishing instruction of the control module 60, and to exhaust air from the target battery pack area.

Optionally, the battery warehousing automatic fire extinguishing apparatus 1 includes a plurality of battery packs 20 and a plurality of first infrared temperature sensors 31, and the first infrared temperature sensors 31 are disposed in one-to-one correspondence with the battery packs 20.

After the battery pack 20 in the battery storage area 10 is out of control due to heat, the temperature of the battery pack 20 may rapidly rise, and further, the battery pack may catch fire and ignite other battery packs 20 in the battery storage area 10, which causes a great hazard, only the temperature of the battery pack 20 is not detected accurately enough, and the temperature change condition in the battery storage area 10 needs to be comprehensively judged by combining the comparison between the ambient temperature and the temperature of the battery pack 20, so as to pre-judge and pre-warn the potentially-catching battery.

Each of the first infrared temperature sensors 31 is provided corresponding to each of the battery packs 20, one of the first infrared temperature sensors 31 detects the temperature of one of the battery packs 20, and the second infrared temperature sensor 32 is provided outside the electric cell storage region 10 to detect the current ambient temperature. After the battery storage automatic fire extinguishing device 1 is powered on, the plurality of first infrared temperature sensors 31 transmit the detected temperature of each battery pack 20 to the control module 60 to obtain the internal temperature information of the battery storage area 10, and when the temperature is abnormal, the abnormal battery pack 20 can be positioned according to the first infrared temperature sensors 31; the second infrared temperature sensor 32 transmits the current ambient temperature to the control module 60, the control module 60 transmits the internal temperature information and the ambient temperature to the data processing platform through the data transmission module 50, the data processing platform judges whether the battery pack 20 at the current fire risk exists in the battery storage area 10 through data processing, and if so, generates alarm data and transmits the alarm data to the control module 60.

The control module 60 transmits an isolation instruction to the isolation device 70 according to the target region location information included in the alarm data, the isolation device 70 is made of a fireproof material, for example, a metal material such as aluminum, iron, steel, or alumina ceramic, and the isolation device 70 individually isolates and locks the target battery pack region. The target battery pack area is an abnormal temperature area and comprises battery packs with fire and the like and battery packs with potential fire risks, and the target battery pack area is quickly isolated in a physical space, so that open fire and heat can be effectively isolated, and the area of the area which can be influenced is reduced.

After the isolation operation is completed, the control module 60 receives the isolation completion signal returned by the isolation device, and then sends a fire extinguishing instruction to the fire extinguishing agent storage module 40, and the fire extinguishing agent storage module 40 releases a fire extinguishing agent to the target battery pack area, wherein the fire extinguishing agent is a fluorine-containing non-toxic fire extinguishing agent, so that air in the target battery pack area can be quickly discharged, the fire of the battery pack in fire is extinguished, and meanwhile, the battery pack with potential fire risk is protected.

Specifically, the isolation device 70 may be a thermal insulation board formed by a stretchable metal plate and a thermal insulation material, and a movement device of the isolation device 70 automatically pushes the thermal insulation board to the target battery pack region according to the alarm data, so as to seal the periphery of the target battery pack region, and form physical isolation between the adjacent battery packs 20. While continuing to monitor the temperature data uploaded by the first infrared temperature sensors 31 in the battery pack 20 area and other location areas. After the isolation is finished, the fire extinguishing agent can be immediately released to the battery pack 20 area, and the fire extinguishing agent can be released when the preset condition is reached according to the subsequent monitoring result; for example, when the temperature of the area of the battery pack 20 continues to rise to a certain set value, or the difference from the ambient temperature reaches a set value, the fire extinguishing agent storage module 40 is controlled to release fire extinguishing agent to the area of the battery pack 20.
