With the fire extinguishing system described above, initially, the storage mechanism 10 is in the closed state and the injection mechanism 30 is in the shut-off state. When the batteries in a certain partition generate heat, the battery management system detects the information of the batteries and sends the detection information to the controller, the controller controls the storage mechanism 10 to enter an open state according to the detection information, and simultaneously controls the injection mechanism 30 corresponding to the partition to enter a conduction state, the high-pressure gas presses the fire extinguishing medium into the first connecting pipeline 20, and then the fire extinguishing medium is injected to the batteries in the battery box 200 of the partition through the first connecting pipeline 20 and the injection mechanism 30 entering the conduction state, so that the heated batteries are cooled and put out a fire. The medium detector 40 may detect the fire extinguishing medium sprayed to the battery through the spraying mechanism 30, i.e. detect whether the fire extinguishing medium passes through the corresponding spraying mechanism 30 and is sprayed out, thereby ensuring that the fire extinguishing medium is sprayed out to cool or extinguish the fire of the battery. So, can accurately cool down or put out a fire to the battery that generates heat to can ensure the fire extinguishing medium blowout in order to guarantee fire extinguishing effect, avoid the thermal runaway, prevent the conflagration to stretch, the protecting effect is good, and the security is high.
In this embodiment, the fire extinguishing medium is a medium such as perfluorohexanone, heptafluoropropane, or carbon dioxide, and the high-pressure gas is nitrogen.
When the battery in a certain section generates heat, the reservoir mechanism 10 is turned on, but only one of the injection mechanisms 30 corresponding to the abnormal section is turned on, and the remaining injection mechanisms 30 corresponding to the normal sections are turned off.

When the battery is heated, the controller acquires detection information of the battery management system, and sends an instruction for opening the container valve 12 to the driver 13, and the driver 13 drives the container valve 12 to open.
Furthermore, it should be noted that the container valve 12 can also be opened manually to facilitate manual opening of the container valve 12 in the event of a failure of the actuator 13.
Further, the storage mechanism 10 further includes a pressure detector 14, the pressure detector 14 is connected to the container valve 12 for detecting the pressure in the fire-extinguishing bottle 11, and the controller is electrically connected to the pressure detector 14. The container valve 12 is opened, and when the injection mechanism 30 enters a conducting state, the fire extinguishing medium in the fire extinguishing bottle 11 is injected to the batteries of the corresponding subareas through the first connecting pipeline 20 and the injection mechanism 30 so as to cool and extinguish fire.
The pressure in the fire extinguishing bottle 11 can reduce in the fire extinguishing medium blowout process, and pressure detector 14 detects the pressure in the fire extinguishing bottle 11, avoids the pressure undersize in the fire extinguishing bottle 11 to lead to the fire extinguishing medium injection pressure not enough. And at the same time, the operator can replace the fire bottle 11 when the pressure detector 14 detects that the pressure inside the fire bottle 11 is too small.
In some embodiments, the fire suppression system includes a plurality of storage mechanisms 10, each storage mechanism 10 being connected to a first connecting conduit 20. When only one storage mechanism 10 exists, there is a problem that fire extinguishing is not completed but the pressure of the fire extinguishing medium sprayed in the fire extinguishing bottle 11 is insufficient due to an insufficient pressure, or the fire extinguishing medium is consumed; when a plurality of storage mechanisms 10 exist, the spraying pressure of the fire extinguishing medium and the amount of the fire extinguishing medium can be ensured, the completion of temperature reduction and fire extinguishing is ensured, and the safety is further improved.
In some embodiments, each spraying mechanism 30 includes a second connecting pipe 31, a partition valve 32 and a plurality of nozzles 33, the second connecting pipe 31 is connected to the first connecting pipe 20, the plurality of nozzles 33 are connected to the second connecting pipe 31, each nozzle 33 is disposed at a corresponding battery box 200 to spray the fire extinguishing medium to the batteries in the battery box 200, and the partition valve 32 is disposed at the second connecting pipe 31 and between the first connecting pipe 20 and the nozzle 33 for controlling the on/off of the second connecting pipe 31.
When the partition valve 32 is opened, the second connection pipe 31 is conducted, and the fire extinguishing medium in the first connection pipe 20 can be sprayed to the battery in the battery box 200 through the second connection pipe 31 and the nozzle 33, that is, the spraying mechanism 30 is in a conducting state; when the partition valve 32 is closed, the second connecting duct 31 is shut off and the fire-extinguishing medium is restricted from passing through the second connecting duct 31, i.e. when the spraying mechanism 30 is in the shut-off state.
In addition, it should be noted that the controller may control the partition valve 32 to open and close for multiple times, so as to conduct and block the second connecting pipe 31 for multiple times, so that the fire extinguishing medium is sprayed to the abnormal partition for multiple times, and continuous suppression of heat generation and fire is achieved.
In practice, the controller is electrically connected to the partition valve 32, and each of the medium detectors 40 is connected to a corresponding one of the second connecting pipes 31 and is located between the partition valve 32 and the nozzle 33. Thus, after the controller acquires the information that the batteries in a certain partition are on fire, the control container valve 12 and the partition valves 32 corresponding to the partitions are opened, so that the fire extinguishing medium is sprayed out to cool and extinguish the fire, the medium detector 40 can detect the fire extinguishing medium passing through the partition valves 32, the fire extinguishing medium passing through the partition valves 32 can be directly sprayed out through the nozzles 33, and the fire extinguishing medium spraying in the partition can be judged after the medium detector 40 detects the fire extinguishing medium.
It is understood that the connection of the medium detector 40 to the controller may be regarded as a feedback mechanism, the controller controls the container valve 12 and the partition valve 32 to be opened and the fire extinguishing medium to be sprayed, and the medium detector 40 detects whether the fire extinguishing medium is sprayed and feeds back the detection result to the controller.

In practical applications, each media detector 40 is electrically connected to a corresponding partition detection module, and the partition detection module forwards information detected by the media detector 40 to the controller.
It should be noted that in other embodiments, the partition control module may be integrated into the controller, but in the embodiment shown in fig. 1, the partition control module is provided separately from the controller.
In some embodiments, each injection mechanism 30 further includes a third connecting conduit 34, and each third connecting conduit 34 is connected between the second connecting conduit 31 and a corresponding nozzle 33.
In some embodiments, the fire extinguishing system further includes a plurality of detectors 50, each detector 50 is disposed in a corresponding battery box 200 for detecting the temperature, gas and solid particles in the battery box 200, so as to detect the information in the battery box 200 when the batteries in the battery box 200 continuously generate heat.
The detector 50 is a composite type, and detects the temperature in the battery box 200 as a temperature sensor, the gas in the battery box 200 as a carbon monoxide sensor, and the solid particles in the battery box 200 as a smoke sensor.
In practical application, the controller is electrically connected to each detector 50, and is configured to control the storage mechanism 10 and the injection mechanism 30 to operate according to monitoring information of the detectors 50 and the battery management system, that is, when both the detectors 50 and the battery management system detect that the battery temperature is higher than a threshold value, or even a fire occurs, the controller controls the storage mechanism 10 to enter an on state, and simultaneously controls the injection mechanism 30 of the corresponding partition to enter a conducting state, so that the fire extinguishing medium is sprayed to the battery in the battery box 200 of the corresponding partition to cool and extinguish the fire. Therefore, the detection accuracy is ensured, and meanwhile, the injection accuracy can be ensured.
In some embodiments, the fire suppression system further comprises an alarm mechanism electrically connected to the controller, and the controller controls the alarm mechanism to act according to the battery management system and the detection information of the detector 50, that is, to give an alarm to remind an operator when there is a problem in the battery, and after the operator acquires the information, the container valve 12 is manually opened when the driver 13 in the storage mechanism 10 fails.
Similarly, the partition valve 32 may be configured to be manually opened, and in the event of a failure of the electrical opening, the operator may manually open the emergency.
In practical application, the alarm mechanism comprises at least two audible and visual alarms, and each audible and visual alarm is electrically connected with the controller. For example, audible and visual alarms are arranged inside and outside the battery compartment to increase the alarm range and ensure that an operator finds an alarm.
In some embodiments, the alarm mechanism further comprises a gas discharge indicator, and the controller is electrically connected to the gas discharge indicator, and when the fire extinguishing medium in the fire extinguishing bottle 11 is sprayed out, the pressure detector 14 detects the pressure decrease, and the gas discharge indicator is also lighted to indicate that the fire extinguishing medium is being discharged.
In order to facilitate understanding of the technical solution of the present invention, the operation flow of the fire extinguishing system in the above embodiment when encountering battery heat and fire will be described:
when a battery in a certain battery box 200 starts to generate heat, the battery management system detects the abnormality of the battery, the detector 50 can also detect the temperature abnormality in the battery box 200, and the controller controls the sound-light alarm to act and give out sound-light alarm so as to facilitate the detection of the actual situation by an operator.
If the battery continues to generate heat and causes the battery to generate a large amount of combustible gas, smoke or even fire, the detector 50 detects the gas and smoke, the battery management system further acquires detection information, and the controller controls the driver 13 to open the container valve 12 according to the detection information of the detector 50 and the battery management system, and simultaneously sends an instruction for opening the partition valve 32 to the corresponding partition control module to open the corresponding partition valve 32. Of course, the controller controls the audible and visual alarm to continuously give an alarm and controls the abandon indicator lamp to light at the moment.
After the container valve 12 and the partition valve 32 are opened, the high-pressure gas in the fire extinguishing bottle 11 pushes out the fire extinguishing medium, and the fire extinguishing medium is sprayed to the batteries in the corresponding partitions through the first connecting pipeline 20, the corresponding second connecting pipelines 31 and the nozzles 33, so that the effects of accurately reducing the temperature and inhibiting the fire are achieved. The medium detector 40 can detect the fire extinguishing medium when the fire extinguishing medium passes through the corresponding second connecting pipeline 31, and the controller judges whether the fire extinguishing medium is sprayed to the corresponding subarea according to the corresponding medium detector 40, so that the spraying accuracy is further ensured. In order to achieve continuous suppression of battery heating, the controller may control the corresponding partition valve 32 to open and close multiple times to spray the fire extinguishing medium multiple times.
In the process of fire extinguishing medium spraying, the pressure in the fire extinguishing bottle 11 continuously reduces, and when the pressure detector 14 detects that the pressure value is lower than the preset value, the controller can also send out the low pressure warning to remind operating personnel to change and store up the fire extinguishing bottle 11.
In addition, it can be understood that, when the batteries in the plurality of subareas generate heat or even fire, the controller may acquire the detection information of the corresponding subarea and control the subarea valve 32 of the corresponding subarea to open according to the detection information, so as to cool and extinguish the fire in the plurality of subareas simultaneously.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
