Two telescopic rods 9 are fixedly installed on one side wall of the connecting rod 7 close to the monitoring camera 11, and a scraper block 10 that fits the outer wall of the monitoring camera 11 is fixedly connected to the telescopic ends of the two telescopic rods 9. The two telescopic rods 9 are both sleeved with a first spring 8. Grooves 24 are provided on the inner walls of both sides of the sleeve block 23, and two symmetrically arranged mounting grooves 26 are provided on the outer wall of the first rotating shaft 17. A convex block 25 is provided in each of the two mounting grooves 26, and the convex block 25 is adapted to the groove 24. A second spring 27 is provided in each of the two mounting grooves 26, and the two ends of the second spring 27 are respectively fixedly connected to the convex block 25 and the inner wall of one end of the mounting groove 26;

[0030] The hollow block 1 is provided with an auxiliary mechanism, which includes an air storage tube 30 fixedly installed on the inner wall of the other side of the hollow block 1, a round rod 29 fixedly installed on one side wall of the sliding block 5 close to the air storage tube 30, a movable plug 31 slidably connected to the inner wall of the air storage tube 30 is provided in the air storage tube 30, a round hole 33 is opened at one end of the air storage tube 30 close to the round rod 29, a tension spring 32 is provided in the air storage tube 30 between the round hole 33 and the movable plug 31, and the two ends of the tension spring 32 are respectively fixedly connected to the movable plug 31 and the inner wall of one end of the air storage tube 30, and the air storage tube 30 is provided with a blowing pipe 13 connected to the interior thereof.

[0031] When the present invention is used, by setting the servo motor 15, the first rotating shaft 17 can be made to intermittently rotate a certain angle, so that the monitoring camera 11 can be made to intermittently rotate a certain angle, change the monitoring range, and realize comprehensive monitoring. When the first rotating shaft 17 rotates, the second spring 27 makes the protrusion 25 and the groove 24 cooperate with each other, so that the sleeve block 23, the connecting rod 7 and the gear 22 can rotate synchronously with the monitoring camera 11. By setting the reducer 16, the first rotating shaft 17 can slowly drive the second rotating shaft 18 to rotate when rotating, and the rotation of the second rotating shaft 18 drives the rotating block 19 to rotate, so that the second electric contact block 21 on the rotating block 19 slowly rotates around the second rotating shaft 18. The axis of the hydraulic cylinder 28 rotates, and when the second rotating shaft 18 rotates to contact with the first electric contact block 20, the circuit of the hydraulic cylinder 28 is connected, so that the hydraulic cylinder 28 completes a telescopic action. When the telescopic end of the hydraulic cylinder 28 is extended, the slot 12, the guide rod 4 and the sliding block 5 are provided, so that the rack 6 and the round rod 29 can move away from the hydraulic cylinder 28. The moving rack 6 is meshed with the gear 22, and the rotation of the gear 22 drives the sleeve block 23 to rotate, and the protrusion 25 is intermittently away from the groove 24. The rotating sleeve block 23 drives the connecting rod 7 to rotate, and finally drives the scraper block 10 to rotate 360 ​​degrees around the axis of the first rotating shaft 17 to scrape the dust on the outer shell of the monitoring camera 11;

[0032] At the same time, the round rod 29 moves and one end of the round rod 29 enters the air storage tube 30 through the round hole 33. The round rod 29 entering the air storage tube 30 contacts the movable plug 31 and pushes the movable plug 31 to slide away from the gear 22. The tension spring 32 is stretched. When the movable plug 31 moves, the air in the air storage tube 30 is squeezed out through the air blowing pipe 13 to blow and dissipate heat for the monitoring camera 11. At the same time, the dust on the outer wall of the monitoring camera 11 can also be blown away. When the hydraulic cylinder 28 is extended, the air in the air storage tube 30 is squeezed out through the air blowing pipe 13 to blow and dissipate heat for the monitoring camera 11. At the same time, the hydraulic cylinder 28 is extended. When the retracted end retracts, the rack 6 and the round rod 29 move toward the direction close to the hydraulic cylinder 28, and the gear 22 and the sleeve block 23 rotate in the opposite direction, thereby causing the scraper block 10 to rotate in the opposite direction around the axis of the first rotating shaft 17 to scrape the dust on the outer wall of the monitoring camera 11 for the second time, thereby improving the dust removal effect. The elastic force generated by the elongation of the tension spring 32 causes the movable plug 31 to return to the initial position, and the external air is filtered and sucked into the air storage pipe 30 through the air inlet pipe 14 for the next blowing, and this reciprocating cycle is repeated.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
