[0020] The monitoring device 2 is protected as a whole by the fixed bracket 7, so that the rack plate 13 and the connecting sleeve 14 reciprocate along the upper surface of the fixed bracket 7, so that the rack plate 13 drives the two gears 12 to rotate relative to each other at the same time, and drives the supporting shaft 8 to rotate relative to each other, so that the rotating supporting shaft 8 drives the connecting plate 9 and the fixed rod 10 to move along the outer surface of the fixed bracket 7, and causes the metal tube 11 to rotate along the outer surface of the monitoring device 2 and collide with each other, which is used to drive away birds and move debris on the outer surface of the monitoring device 2, reflecting the cleaning effect of the fixed rod 10 and the metal tube 11 on the outer surface of the monitoring device 2.
[0021] Reference Figure 1 and Figure 2 The rotating mechanism includes a support plate 15, which is fixedly mounted on the top of the rear end surface of the fixed bracket 7. A servo motor 16 is mounted on the upper surface of the support plate 15. A movable circular plate 17 is mounted on the output end of the upper surface of the servo motor 16. The top edge of the movable circular plate 17 is fixedly connected to a limit lever 18. A fixed long slot is formed through the top of the connecting sleeve 14. The outer diameter of the limit lever 18 is smaller than the distance between the two sides of the inner wall of the fixed long slot. One side of the outer surface of the limit lever 18 is located inside the fixed long slot, and the limit lever 18 and the fixed long slot are embedded in each other.
[0022] By making the pressure sensor 3 control the servo motor 16 to open and close, the servo motor 16 is started to drive the movable circular plate 17 to rotate, so that the movable circular plate 17 rotates and drives the limit lever 18 to move along the inside of the connecting sleeve 14, so that the limit lever 18 controls the rack plate 13 and the connecting sleeve 14 to reciprocate, reflecting the reciprocating movement adjustment effect of the connecting sleeve 14 and the rack plate 13.

The wheel 12 rotates relative to itself and drives the supporting shaft 8 to rotate relative to itself, so that the rotating supporting shaft 8 drives the connecting plate 9 and the fixing rod 10 to move along the outer surface of the fixing bracket 7, so that the metal tube 11 rotates along the outer surface of the monitoring device 2 and collides with each other, which is used to drive away birds and move debris on the outer surface of the monitoring device 2, keep the outer surface of the monitoring device 2 in a tidy state, and prevent debris in the environment from blocking the line of sight of the monitoring device 2.
