[0041] When the lens of the detection camera 2 needs to be cleaned because dust is attached to the lens, reference Figures 1-6 , the lens of the detection camera 2 is inserted into the cleaning box 3 through the cooperation of the motor sliding table 37 and the first electric push rod 42, a rotating joint for air is arranged below the hollow column 32, when the hollow column 32 rotates, air can flow into the air blowing nozzle 5 through the hollow column 32 and the pipeline, so that the dust and particles on the lens of the detection camera 2 are cleaned, a rotating joint for water is arranged at the lower end of the second abutting rod 33, a flow channel is arranged on the second abutting rod 33 and is connected with the flushing nozzle 9 through a pipeline, so that the flushing nozzle 9 sprays cleaning liquid on the wiping piece 7 to wash away the dust, at the same time, the second electric push rod 43 drives the first abutting frame 14 to move horizontally in the cleaning box 3, so that the trapezoidal abutting block 15 fixed on the first abutting frame 14 abuts against the first abutting rod 12, the first abutting rod 12 drives the wave abutting ring 6 to move upwards, the first spring 13 stores energy, at the same time, the motor shaft of the servo motor 41 drives the second gear 40 to rotate, so that the toothed disc 39 drives the hollow column 32 to rotate in the cleaning box 3, the cleaning seat 4 and the strip-shaped frame 16 rotate synchronously, the second abutting frame 27 and the wave abutting ring 6 intermittently abut against each other, the third spring 28 continuously stores energy and releases the elastic force, so that the second abutting frame 27 reciprocatingly moved by abutting against each other abuts against one end of the first rack 25 in the strip-shaped frame 16, the first rack 25 drives the first gear 24 to deflect and slide on the strip-shaped frame 16, the second spring 26 continuously stores energy and releases the elastic force, so that the first rotating shaft 17 drives the air blowing nozzle 5 to deflect on the strip-shaped frame 16, the air blowing range of the air blowing nozzle 5 is increased, and the cleaning dead angle is reduced;

[0042] At the same time, the first I-shaped rack 30 intermittently contacts the wave-shaped contact ring 6, causing the first I-shaped rack 30 to move vertically within the cleaning seat 4. The fourth spring 31 continuously stores and releases its elastic force. The first I-shaped rack 30 meshes with the arc-shaped toothed block 29 fixed on the second rotating shaft 19, thereby causing the squeezing plates 8 on both sides to deflect and continuously squeeze the rinsed wiping pad 7 to remove excess water.
