[0030] In summary:

[0031] By starting the motor 6 to drive the screw 7 to rotate, the screw 7 causes the screw sleeve 8 to produce a lateral displacement along the guide rod, and the screw sleeve 8 then drives the mounting block 9 on one side of the outer ring and moves the outer shell 19 through the clamping block 10, thereby driving the brush barrel 15 and the two sticky rollers 17 to move back and forth to the camera position on one side of the camera 5 to clean the camera. The rotational connection between the brush barrel 15 and the inner wall of the outer shell 19 allows the multiple bristles of the brush barrel 15 to contact the camera position and drive the brush barrel 15 to rotate. Similarly, the two sticky rollers 17 rotate in the U-shaped plate, thereby making the brush barrel 15 and the two sticky rollers 17 produce the effect of moving and rotating at the same time, thereby improving the cleaning effect of the camera, reducing the operating burden of personnel, and improving the practicality of the unmanned vehicle.

[0032] By holding the pull block and pulling the pull rod 13 to move, the pull rod 13 then drives the limit plate 12 to move and squeezes the spring 14. When the pull rod 13 moves, one end is removed from the slot to release the positioning of the block 10, making it convenient for personnel to disassemble the shell 19 and remove the brush tube 15 and the adhesive roller 17 for replacement or maintenance. During installation, the block 10 is connected to the inside of the slot, and then the pull block is released so that the spring 14 loses the extrusion force and elastically pushes the limit plate 12 back to its position. The limit plate 12 then drives the pull rod 13 back to its position and inserts one end of it into the jack and the slot to complete the positioning between the block 10 and the mounting block 9, and then fixes the shell 19, so as to facilitate personnel to easily load and unload the brush tube 15 and the adhesive roller 17 to keep them in good condition, improve the cleaning function and effect, and improve its operation convenience.
