[0041] The movable component 2 includes a ball screw 21 and an auxiliary rod 25. The ball screw 21 is provided with a ball nut that mates with it. The auxiliary rod 25 is fitted with a movable block. Both the movable block and the ball nut are provided with movable plates 22. A mounting plate 26 is provided between the two movable plates 22. The cleaning component 3 is provided on the outer shell 31. One end of the ball screw 21 is connected to a drive motor 24. When the ball screw 21 rotates, the ball nut that mates with it can move linearly up and down. The ball nut can drive the movable plate 22 connected to it to move, and then the mounting plate 26 can drive the cleaning component 3 to move up and down for use.

[0042] Positioning plates 23 are provided on the ball screw 21, auxiliary rod 25, and drive motor 24. The ball screw 21, auxiliary rod 25, and drive motor 24 are all mounted on the testing equipment 1 through the positioning plates 23. The positioning plates 23 securely mount the ball screw 21, auxiliary rod 25, and drive motor 24 on the testing equipment 1, ensuring the stability and reliability of the entire cleaning system.

[0043] In use, the infrared sensor on the detection device 1 detects the height of passing vehicles. Every certain period of time, the drive motor 24 and the drive motor 331 are started. The output shaft of the drive motor 24 drives the ball screw 21 connected to it to rotate, causing the ball nut on the ball screw 21 to move up and down linearly. When the ball nut moves, it drives the mounting plate 26 to move together through the connecting plate 321 connected to it, and then drives the moving plate 22 connected to the auxiliary rod 25 to move, so that the two moving plates 22 move up and down synchronously. When the mounting plate 26 moves up and down, it drives the cleaning part 3 to move together, so that the cleaning cloth 34 on the cleaning part 3 contacts the position to be wiped on the detection device 1 and moves up and down, thereby cleaning the detection device 1 thoroughly from top to bottom.

[0044] The output shaft of the second drive motor 331 drives the second gear 333 to rotate, and the second gear 333 drives the gear 332 meshing with it to rotate. Then the toothed belt 334 runs, and the toothed belt 334 makes multiple gears 332 rotate synchronously. When the gears 332 rotate, they can drive the drive roller 322 connected to them to rotate. The multiple drive rollers 322 rotate synchronously in the same direction, which can drive the sleeved cleaning cloth 34 to move in a cycle. This makes the cleaning cloth 34 not wipe the same place back and forth when wiping the detection device 1, thus improving the wiping effect of the detection device 1.

[0045] When the cleaning cloth 34 needs to be replaced, the mounting plate 26 is separated from the outer casing 31. Then, the connecting plate 321 can be pulled outward. The connecting plate 321 pulls the rod 3221 and the auxiliary roller 323 outward, allowing the cleaning cloth 34 to be removed from the outer casing 31 for cleaning and replacement. After the replaced cleaning cloth 34 is placed on the rod 3221 and the auxiliary roller 323, the rod 3221 and the auxiliary roller 323 are inserted back into the mounting opening. In the outer casing 31, the insertion end 3222 on the first rod 3221 is inserted into the insertion slot 3224 on the second rod 3223, so that the first rod 3221 and the second rod 3223 are inserted and combined to form the drive roller 322. The end of the auxiliary roller 323 away from the connecting plate 321 is inserted into the slot on the outer casing 31, so that the cleaning cloth 34 inside the cleaning component can be taken out for replacement, and it is also convenient for the user to install the cleaning cloth 34 back into the outer casing 31 after replacing it.
