[0002] As global environmental and energy issues become increasingly severe, countries around the world are vigorously promoting the development and popularization of the electric vehicle industry. As the mainstream of new energy vehicles, electric vehicles have also become an inevitable trend in the development of my country's automobile industry. Their favorable prices, convenient charging, and ability to meet the daily travel needs of ordinary people have made electric vehicles a travel choice for many young people, but the accompanying safety hazards are also issues that cannot be ignored.

[0003] In recent years, new energy vehicle (electric vehicle) fire accidents have occurred frequently, and electric (gasoline) vehicles have become a major fire disaster area. According to incomplete statistics, more than 65% of spontaneous combustion fire accidents involving electric vehicles occurred during the charging process. Due to limited space resources, most of the newly added electric vehicle charging spaces are installed in underground parking garages of various buildings, and the charging process of electric vehicle lithium batteries is a high-probability period for combustion or explosion: once the battery burns, it will not only destroy the vehicle itself, but also the surrounding vehicles and buildings, which is very likely to cause secondary hazards and will destroy surrounding vehicles and buildings in a very short time. The toxic gases released are also very dangerous to the human body.

[0004] At present, ordinary fire extinguishing systems cannot effectively extinguish fires in power batteries, and therefore cannot better deal with the isolation and extinguishing of electric vehicle fires.

[0032] The working principle of the utility model: the agent ball valve is normally kept open and waits for instructions. Once a fire alarm occurs, the built-in sensing element of the sprinkler head responds quickly and triggers the burst mechanism. Then, the high-efficiency fire extinguishing agent stored in the fire extinguishing agent tank passes through the precisely designed agent circulation pipeline, smoothly passes through the double checkpoints of the agent ball valve and the agent check valve, and directly reaches the sprinkler network. Finally, these fire extinguishing agents are evenly sprayed through densely arranged sprinkler heads, quickly suppressing the fire and achieving efficient fire extinguishing.

After receiving the signal, the module immediately starts the advanced algorithm analysis. After confirming that the fire is true, it immediately triggers the alarm system and notifies the person holding the handheld terminal through the communication module, ensuring that the personnel can quickly learn of the dangerous situation and intervene to deal with it, greatly improving the speed and efficiency of fire response.

[0034] When the fire extinguishing agent inventory is exhausted and the pressure in the pipeline drops to zero, the IoT agent pressure gauge installed in the system immediately captures this critical information. Its built-in pressure sensor instantly feeds back this change to the processing module. After receiving the signal, the latter activates the cooling solenoid valve or the tap water supply solenoid valve after intelligent judgment. Subsequently, the cooling water stored in the cooling water tank or the water flow directly from the tap water network is directed to the fire scene and continuously sprayed through the sprinkler head, effectively reducing the temperature at the scene, blocking the risk of re-ignition caused by high temperature from the root, and further consolidating the fire extinguishing results.
