the vehicle starts, and the driver opens the work switch of sucking disc, and the relay main contact in the controller is closed, and the gas circuit solenoid valve is closed, and the 6 piston rods of cylinder stretch out and drive mechanism and rotate under the atmospheric pressure thrust effect. The transmission mechanism rotates and simultaneously drives the rotating shaft assembly 3 and the side spray rod 54 assembly to rotate, in the process, the side spray rod 54 slowly swings out, and high-pressure atomized water is sprayed out along with the connection of a water path to clean the road surface and the road edge stone. Meanwhile, the ultrasonic ranging sensor starts to work, continuously sends out ultrasonic signals and receives the fed-back ultrasonic signals. The ultrasonic ranging sensor then converts the received feedback ultrasonic signal to a voltage analog signal 1 (the voltage analog signal 1 is a negative ratio of the distance of the side nozzle 54 assembly from the obstacle), and transmits the voltage analog signal 1 to the controller.

However, when the distance from the side boom 54 assembly to the obstacle is not greater than 80mm, the voltage analog signal 1 is not less than the voltage threshold set by the voltage threshold signal 2. At the moment, the controller judges that the vehicle is dangerous at present, the controller can output a relay enabling signal, the relay and the gas circuit electromagnetic valve can be disconnected, the piston rod of the air cylinder 6 retracts, and the side spray rod 54 is retracted to a safe position, so that the side spray rod 54 can effectively avoid the obstacle when encountering the obstacle in the vehicle operation process, the side spray rod 54 cannot be damaged by collision, and the service life of the side spray rod is prolonged. After the ultrasonic distance measuring sensor detects that the distance between the side spray rod 54 assembly and the obstacle is greater than 80mm, the controller does not output a relay enabling signal, the relay and the air path electromagnetic valve are closed, the piston rod of the air cylinder 6 extends out, and the side spray rod 54 continues to swing out and continues normal water spraying operation.
