An adjusting mechanism is installed inside the installation frame 17, so as to protect the two camera bodies 18 below the connecting rod 3, ensure that foreign objects in the air will not directly fall onto the surfaces of the protective cover 16 and the camera body 18 to cause damage to them. At the same time, the first rack 4 and the second rack 5 can be used to move the position of the camera body 18 synchronously, and the water shielding curtain 2 can be unfolded along the moving track of the camera body 18, ensuring that the camera body 18 can be protected from above by the water shielding curtain 2 at different positions.

[0021] Refer to Figure 3, a positioning frame is installed at the top of the connecting rod 3, and the top of the powerful motor 11 is fixedly connected to the positioning frame. The sides of the magnetic disk 12 close to the magnetic sheet 14 are respectively the N pole and the S pole.

[0022] Refer to Figures 5-7, the wiping mechanism includes a frame 19 installed on one side of the mounting frame 17. A rotating motor 20 is installed on the inner wall of the frame 19. The power output shaft of the rotating motor 20 is fixedly connected to a lead screw 21. A slider 22 is threadedly connected to the outer edge of the lead screw 21. A downward moving plate 24 is installed at the bottom of the slider 22. A support 25 is fixedly installed at the top of the downward moving plate 24.

One end of a plurality of compression springs 28 is fixedly connected to the bottom of the turntable 27, and the other end of the plurality of compression springs 28 is fixedly connected to a wiping cotton board 29. It is possible to drive the rotating motor 20 to drive the lead screw 21 to rotate, and then the downward moving plate 24 can be driven by the slider 22 to move downward until the downward moving plate 24 passes through the through hole 42 and contacts the lens of the camera body 18. And with the buffering of the compression springs 28, it can adapt to different distances between the wiping cotton board 29 and the camera body 18, improving the comprehensiveness of cleaning. A push-up spring 23 is sleeved on the outer edge of the lead screw 21, and the push-up spring 23 is arranged inside the frame 19. The slider 22 is slidably connected to the inner wall of the frame 19. A through hole 42 is opened on the inner wall of the mounting frame 17. The downward moving plate 24 is slidably connected to the inner wall of the through hole 42. The outer edge of the lead screw 21 near the push-up spring 23 is smooth, and the bottom end of the lead screw 21 is rotatably connected to the inner wall of the frame 19. So that after the slider 22 moves to the smooth area of the outer edge of the lead screw 21, when the lead screw 21 continues to rotate, the slider 22 and the electromagnetic transmission wheel 30 will not easily move in position. At this time, the transmission belt 31 can be used to drive the metal transmission wheel 32, the linkage rod 26 and the wiping cotton board 29 to rotate continuously, and then it can be used to wipe and clean the lens of the camera body 18. After the cleaning is completed, the lead screw 21 rotates in the reverse direction and moves upward, and the elastic force of the push-up spring 23 can be used to provide a thrust, and then the downward moving plate 24 and the wiping cotton board 29 can be synchronously moved to a high position to disconnect from the camera body 18. The adjusting mechanism includes a servo motor 33. The servo motor 33 is installed on the inner wall of the protective cover 16. The power output shaft of the servo motor 33 is fixedly connected to a linkage wheel 34. A transmission wheel 35 is rotatably connected to the inner wall of the mounting frame 17. A toothed belt 36 is sleeved on the inner walls of the transmission wheel 35 and the toothed belt 36. The transmission wheel 35 is fixedly connected to the camera body 18, and the camera body 18 is rotatably connected to the inner wall of the mounting frame 17. So that driving the servo motor 33 to drive the linkage wheel 34 to rotate, and then the transmission wheel 35 and the camera body 18 can be driven to rotate by the toothed belt 36, realizing the angle adjustment of the camera body 18, adjusting it to an inclined state, and then monitoring at different angles. And the lens of the camera body 18 can be moved upward, which is convenient for the wiping mechanism to clean the lens of the camera body 18.

[0023] Refer to Figure 9The outer edge of the transmission wheel 35 is fixedly installed with a limit gear 37, and the inner wall of the mounting frame 17 is fixedly installed with a vertical plate 38. One side of the vertical plate 38 is fixedly connected to one end of a return spring 39, and the other end of the return spring 39 is fixedly connected to a clamping block 40. The outer side of the clamping block 40 is fixedly connected to a guide column 41, and the guide column 41 is inserted into the inner wall of the vertical plate 38. The clamping block 40 is inserted into the gear tooth gap of the limit gear 37. The side of the clamping block 40 close to the limit gear 37 is arc-shaped, so that the elastic force of the return spring 39 can be used to push the clamping block 40 to be inserted into the gear tooth gap of the limit gear 37, and then it is used to position the transmission wheel 35 and the camera body 18, to ensure that the camera body 18 will not swing easily when the wind blows, and can continue to be in the same state. At the same time, when the limit gear 37 rotates, it can be pushed away by the arc shape of the clamping block 40, so as not to affect the normal operation of the transmission wheel 35 and the limit gear 37.

[0024] See also Figure 7 The outer edge of the lead screw 21 is slidably connected with an electromagnetic transmission wheel 30, and the outer edge of the linkage rod 26 is fixedly installed with a metal transmission wheel 32. The inner walls of the electromagnetic transmission wheel 30 and the metal transmission wheel 32 are sleeved with a transmission belt 31. The bottom of the electromagnetic transmission wheel 30 is rotatably connected with the top of the slider 22, so that when the lead screw 21 rotates, the transmission belt 31 can be used to drive the metal transmission wheel 32 and the linkage rod 26 to rotate, thereby realizing force transmission, and then it can be used to drive the wiping cotton plate 29 to rotate to wipe the lens, reducing the loss of electric energy. After the electromagnetic transmission wheel 30 and the wiping cotton plate 29 are moved to the specified position, the magnetic attraction force can be used to stably adsorb and connect the electromagnetic transmission wheel 30 and the lead screw 21, ensuring that the electromagnetic transmission wheel 30 can rotate synchronously when the lead screw 21 rotates, thereby realizing rotational force transmission.

[0025] See also Figure 6 A through groove is provided at the top of the mounting frame 17, and the toothed belt 36 is passed through the inner wall of the through groove, so that the toothed belt 36 will not interfere with or rub against the mounting frame 17 during operation, thereby preventing damage. At the same time, the toothed belt 36 will not be directly exposed to the outside, thereby improving the protection effect of the toothed belt 36.

[0026] See also Figure 1 and Figure 2 The number of sliding rods 15, protective covers 16, mounting brackets 17 and camera bodies 18 are all two, and the two sliding rods 15, protective covers 16, mounting brackets 17 and camera bodies 18 are symmetrically arranged below the connecting rod 3, and the other sliding rod 15 is fixedly connected to the bottom of the connecting rod 3, so that the parallax of the two camera bodies 18 can be used to calculate the distance of the object and generate a depth map, and the monitoring range can be increased, the blind spots can be reduced, and the comprehensiveness of the monitoring can be further improved.

[0027] See also Figure 7, the turntable 27 is rotatably connected to the inner wall of the downward moving plate 24. The wiping cotton plate 29 is made of sponge, which can ensure the stability of the turntable 27 when rotating on the inner wall of the downward moving plate 24, and can ensure that it will not easily shift during rotation. Moreover, the sponge material is relatively soft, which can ensure that the lens of the camera body 18 will not be scratched when being wiped, thus ensuring the cleaning effect.

[0028] Working principle: First, the servo motor 33 can be driven to drive the linkage wheel 34 to rotate. Then, the toothed belt 36 can be used to drive the transmission wheel 35 and the camera body 18 to rotate, so as to realize the angle adjustment of the camera body 18, adjust it to an inclined state, and then monitor different angles. Moreover, the lens of the camera body 18 can be set facing upward. Then, the rotary motor 20 can be driven to drive the lead screw 21 to rotate. Then, the slider 22 can be used to drive the downward moving plate 24 to move downward. Until the slider 22 moves to the smooth area on the outer edge of the lead screw 21, the slider 22 and the electromagnetic transmission wheel 30 will not easily move when the lead screw 21 continues to rotate. At this time, the transmission belt 31 can be used to drive the metal transmission wheel 32, the linkage rod 26 and the wiping cotton plate 29 to rotate continuously, so as to wipe and clean the lens of the camera body 18. After the cleaning is completed, the lead screw 21 rotates in the reverse direction and moves upward, and the elastic force of the upward pushing spring 23 can be used to provide thrust, so as to synchronously move the downward moving plate 24 and the wiping cotton plate 29 to a high position and disconnect them from the camera body 18 to complete the cleaning operation; Finally, the powerful motor 11 can be driven to drive the driving wheel 7 and the magnetic disk 12 to rotate. When the magnetic disk 12 rotates 180 degrees until the side where the magnetic disk 12 and the magnetic sheet 14 are close to each other is the same magnetic pole, the sliding piece 13 can be pushed to slide on the inner wall of the connecting rod 3 by the repulsive force of the same sex, so as to accelerate the speed when the sliding rod 15 initially drives the protective cover 16 to move. At the same time, the driving wheel 7 can cooperate with the belt 43 to drive the driven wheel 8 to rotate. Then, the driven wheel 8 drives the two transmission gears 10 to rotate through the rotating rod 9. Synchronously, the rack one 4 and the rack two 5 can be driven to slide on the inner walls of the cross bar 1 and the connecting rod 3 respectively, so as to move the position of the camera body 18 respectively, and follow the moving track of the camera body 18 to unfold the water blocking curtain 2, so as to ensure that the camera body 18 can be protected from high places by the water blocking curtain 2 at different positions.
