[0026] The tire limiting stop 5 is provided with a plurality of expansion bolt mounting holes along the length direction, and can be fixed in the parking space 6 by expansion screws.

[0027] The spraying device 8 and the smoke extraction device 9, smoke sensing and temperature sensing devices, alarm bells and infrared transmission alarm devices, etc. can be arranged above the parking space, and when a fire is detected, the spraying device 8 and the smoke extraction device 9 can be synchronously sprayed to extinguish the fire and extract smoke dust.

[0028] In the preferred embodiment, a total pipeline 1 and a plurality of independent first branch pipelines 2 in communication with the total pipeline 1 are further arranged, one end of the first branch pipeline 2 is in communication with the liquid inlet joint 503, and the first branch pipeline 2 is provided with a first switch valve 201.

[0030] Each valve body is electrically connected with an external total control system, and the total pipeline 1 is in communication with a fire extinguishing system pipeline and a pipeline total control valve.

[0031] The detection sensor 7 can be provided with two, respectively, a temperature sensor and a flame sensor, the temperature sensor senses the temperature at the parking space, the flame sensor uses a far infrared flame probe to convert the change of external infrared light into the change of output voltage, which is expressed as a numerical change through an A / D converter. The stronger the external infrared light, the smaller the value, so the closer to the heat source, the smaller the value of the flame sensor displayed by the host computer. According to the change of the flame sensor value sampled by the AD, the strength of the infrared light can be judged, and thus the distance of the heat source from the fire-fighting robot can be roughly judged. The flame sensor is very sensitive to the flame spectrum in the detection range, and can accurately detect the flame target in the range. The larger the flame of the combustible material, the farther the effective distance of the flame sensor for detection.

[0032] Since the tire limiting stop 5 is arranged at the rear wheel position of the vehicle bottom, it is closer to the position of the battery module of the vehicle. When the detection sensor 7 detects that the temperature is too high or there is an open flame, the first switch valve 201 and the second switch valve 401 are both opened to avoid failure of one of them. The nozzle 502 sprays fire-fighting foam to the vehicle bottom, and the foam diffuses to the vehicle bottom to isolate air, thereby achieving the effect of extinguishing fire.

[0033] In the preferred embodiment, the tire limiting stop 5 is provided with a hollow inner cavity, the blind pipe 501 is rotatably sleeved with the hollow inner cavity of the tire limiting stop 5, and the length of the strip-shaped slot 504 is greater than the outer diameter of the nozzle 502 so that the nozzle 502 can swing at an angle.

[0034] In the preferred embodiment, the tire limiting stop 5 is provided with a hollow inner cavity, the blind pipe 501 is rotatably sleeved with the hollow inner cavity of the tire limiting stop 5, and the length of the strip-shaped slot 504 is greater than the outer diameter of the nozzle 502 so that the nozzle 502 can swing at an angle.

[0035] The blind pipe 501 is provided with a pipe threaded hole at a certain length, and during installation, the blind pipe 501 is inserted into the hollow inner cavity of the tire limiting stop 5, and then each nozzle 502 is rotated into the pipe threaded hole from the strip-shaped slot 504. Since the strip-shaped slot 504 is strip-shaped, each nozzle 502 can swing up and down to uniformly adjust the spray angle. After the angle is adjusted, the blind pipe 501 can be clamped at both ends by rotating the locking knob 508 to lock the angle.

[0036] In the preferred embodiment, the inclined stop surface 505 is provided with a plurality of clamping grooves 507 along the length direction, and each clamping groove 507 is provided with a buffer block 506.
