[0028] The dustproof mechanism 200 comprises a driving assembly 201 matched with the intermittent cleaning of the surface dust of the detection lens 104 and a delay assembly 202.

[0029] Specifically, the driving assembly 201 comprises a motor 201a adaptively installed in the inner cavity of the mounting box 106, a connecting column 201b fixedly installed on the output end of the motor 201a through a shaft coupling, a rotating rod 201c fixedly connected to the other end of the connecting column 201b, and a fixed column 201d fixedly installed on the outer surface of the rotating rod 201c.

[0030] It should be noted that the motor 201a serves as a power source to provide rotary motion, and the connecting column 201b is used to transmit the rotary power of the motor 201a and drive the rotating rod 201c and the fixed column 201d to rotate synchronously.

[0031] Further, the driving assembly 201 further comprises a movable frame 201e slidably sleeved on the outer surface of the fixed column 201d, a rack 201f fixedly connected to the outer surface of the movable frame 201e, and a support block 201g fixedly connected to the top of the bearing box 103 and matched with the rack 201f.

[0032] It should be noted that through the cooperation of the fixed column 201d and the movable frame 201e, the rack 201f is driven to move linearly along the inner wall of the support block 201g.

[0033] Preferably, the inner cavity of the bearing box 103 is provided with a battery matched with the detection lens 104, the mounting box 106 is used to provide a mounting space for the driving assembly 201, and the outer surface of the rack 201f is in sliding contact with the inner wall of the support block 201g.

[0034] It should be explained that the delay component 202 comprises a gear 202a engaged with the outer surface of the rack 201f, a support column 202b fixedly connected to the inner surface of the gear 202a, a rotating disc 202c fixedly sleeved on the outer surface of the support column 202b, and a driving wheel 202d and a brake wheel 202e fixedly connected to the two side surfaces of the rotating disc 202c respectively.

[0035] The rack 201f reciprocating movement drives the gear 202a and the support column 202b to reciprocate, and the support column 202b drives the rotating disc 202c, the driving wheel 202d and the brake wheel 202e to synchronously reciprocate.

[0036] Further, the delay component 202 further comprises a grooved wheel 202f arranged outside the rotating disc 202c and cooperating with the driving wheel 202d and the brake wheel 202e, a transmission rod 202g fixedly connected to the inner surface of the grooved wheel 202f, and a swing rod 202h fixedly sleeved on the outer surface of the transmission rod 202g and cooperating with the detection lens 104.
