[0037] The working principle of the intelligent automobile thermal runaway fire extinguishing device of the present invention is as follows:

[0038] First, the design is installed on the battery of the smart car, so that the nano-alumina bin 4 and the cooling and conveying structure 5 are located on both sides of the battery, and the fire extinguishing agent bin structure 3 is located on the top side of the battery, and then the liquid inlet pipe 52 and the liquid outlet end 58 are connected to the external sodium hydroxide solution end to use the design;

[0039] Second, control and start the second servo motor 536 to rotate the valve block 535 to contact and fit with the first liquid dispensing pipe 533, so that the main liquid pipe 532 is connected with the second liquid dispensing pipe 534, and then control the external sodium hydroxide solution to enter the main liquid pipe 532. After the coolant passes through the second liquid dispensing pipe 534, it flows in the coolant pipe 62 to drive the heat of the car battery, and after absorbing the heat, it passes through the connecting pipe end 57 to enter the arrangement pipe 56 under the action of the fan 59 for cooling treatment. The sodium hydroxide solution after cooling treatment flows back to the external sodium hydroxide solution end for recycling;

[0040] Third, when the monitoring sensor located inside the battery detects that the temperature is abnormally high or a fire source is generated, the first servo motor 332 and the second servo motor 536 can be controlled to start, and the first threaded rod 334 and the second threaded rod 336 are synchronously rotated under the action of the first servo motor 332, and the first threaded rod 334 cooperates with the first internal threaded sleeve 338, and the second threaded rod 336 cooperates with the second internal threaded sleeve 339, so that the first V-shaped rotating rod 3310 and the second V-shaped rotating rod 3311 are unfolded under the action of the first internal threaded sleeve 338 and the second internal threaded sleeve 339, so that the first cross frame 34 and the second cross frame 34 are rotated synchronously. The two horizontal frames 35 are synchronously shifted inwards, so that the two first sealing blocks 36 and the two second sealing blocks 37 are out of contact with the four rectangular grooves 38, so that the internal fire extinguishing material is discharged through the rectangular grooves 38 and covers the battery for fire extinguishing treatment, and the second servo motor 536 is controlled to rotate the valve block 535 to contact and fit with the second liquid distribution pipe 534, so that the main liquid pipe 532 is connected with the first liquid distribution pipe 533, and the coolant enters the fire extinguishing pipe 63 after passing through the first liquid distribution pipe 533, and the coolant is formed into tiny particles under the action of the atomizing nozzle 64, which can effectively absorb heat and extinguish the fire;

[0041] Fourth, when the automobile battery is squeezed or collided to cause the battery to deform, the nano-alumina in the nano-alumina bin 4 can be squeezed out, absorbing heat and generating non-combustion products such as water vapor at the same time, which plays a role in extinguishing the fire, and the top column 55 penetrates the left side of the bin seat 51 to discharge the carbon nanotubes 54 to the outside. The carbon nanotubes can quickly conduct heat to the surrounding environment, reduce the fire temperature, and help extinguish the fire. When the rectangular bin 31 is squeezed, the top block pushes the first cross frame 34 and the second cross frame 35 to drive the two first sealing blocks 36 and the second sealing blocks 37 to break contact with the rectangular groove 38, so that the internal fire extinguishing material can be discharged for fire extinguishing.
