[0023] Refer to Figure 1 、 Figure 3, a support base 2 is fixedly connected to the outer side wall of the mounting plate 1 by bolts. On the outer side wall of the support base 2, a sleeve 4 is fixedly connected. A through opening 10 is formed on the side surface of the sleeve 4. On the inner walls of both sides of the through opening 10, a support frame 11 is fixedly connected. A fan 12 is rotatably connected to the outer side wall of the support frame 11.

[0024] Refer to Figure 1 , Figure 3 , a first protective cover 13 is fixedly connected to the through opening 10 on the sleeve 4. The cross-section of the first protective cover 13 is square. The first protective cover 13 is located outside the ventilation opening 14. Ventilation openings 14 are formed on the outer side walls of both sides of the first protective cover 13.

[0025] Refer to Figure 4 , a support base 2 is fixedly connected to the outer side wall of the mounting plate 1 by bolts. An electric push rod 3 is fixedly connected to the outer side wall of the support base 2 away from the mounting plate 1. A fixed rod 15 is fixedly connected to the outer side wall of the mounting plate 1. One end of the fixed rod 15 away from the mounting plate 1 is fixedly connected to the side surface of the sleeve 4. The telescopic end of the electric push rod 3 is fixedly connected to an L-shaped bracket 16. A motor 17 is fixedly connected to the top of the L-shaped bracket 16.

A second protective cover 20 is fixedly connected to the outer side wall of the L-shaped bracket 16.

[0026] Working principle: In freezing rain weather, the cold air will cause the rainwater falling on the outer side wall of the sleeve 4 to condense into ice. At this time, the sleeve 4 cannot extend and retract normally; start the electric push rod 3, and the telescopic end of the electric push rod 3 drives the connecting disk 9 to contract synchronously. Since one end of the connecting disk 9 is rotatably connected to the steering cylinder 7, the connecting disk 9 drives the position of the steering cylinder 7 to change when moving. Two convex blocks 6 are fixedly connected to the outer side wall of the steering cylinder 7. Two clamping grooves 5 are formed on the inner side wall of the sleeve 4, and the two convex blocks 6 are located inside the two clamping grooves 5. Since the two clamping grooves 5 are set as grooves with a curvature, when the two convex blocks 6 slide along the tracks of the two clamping grooves 5, they will drive the steering cylinder 7 to rotate along the track of the clamping groove 5. When the steering cylinder 7 rotates and contracts, the ice cubes condensed at the connection between the steering cylinder 7 and the sleeve 4 will be broken under the rotation of the steering cylinder 7, so that the ice cubes condensed on the surface of the sleeve 4 will rotate and fall off, avoiding the clamping of the sleeve 4;

[0027] When the monitoring screen is blocked, start the electric push rod 3, and the telescopic end of the electric push rod 3 drives the L-shaped bracket 16 to move, so as to adjust the position of the camera body 18, improve the viewing range of the camera body 18, and reduce the occlusion of the surrounding obstacles to the camera body 18;

[0028] When the climate is hot, the fan 12 can be started, and the wind generated by the rotation of the fan 12 can increase the air circulation speed inside the sleeve 4 and reduce the temperature inside the sleeve 4.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
