When the power supply is connected, the device can be used normally. When a vehicle passes by, the water pump 5 is controlled to operate to extract the water source inside the water tank 8, and finally spray it on the vehicle through the nozzle 3. When the nozzle is blocked, the stepper motor 210 can be controlled to operate. The operation of the stepper motor 210 can drive the rotating shaft 209 fixed at the output end of the stepper motor 210 to rotate, thereby driving the threaded shaft 208 fixed at the left end of the rotating shaft 209 to rotate, thereby cooperating with the relationship between the outer surface of the threaded shaft 208 and the inner wall of the rectangular block 201 to push the two rectangular blocks. 201 moves away from the rectangular box 1, and the second fixing frame 206 fixed on the upper surface of the rectangular block 201 and the second rotating shaft 207 rotatably connected to the inner wall of the second fixing frame 206 will slowly change the angle of the transmission plate 203 under the premise of the movement of the rectangular block 201, so that the pipe 202 fixed to the inner wall of the first fixing frame 204 can be slowly lowered through the transmission plate 203 until the pipe 202 is lowered to the height of the worker's face, so that the worker can disassemble and replace it conveniently, thereby effectively avoiding the device from being easily blocked when the nozzle 3 is working in an environment with a lot of dust during use. After being blocked, the worker needs to climb to a high place with the help of a ladder to replace it, which poses a certain safety hazard.
