[0049] The meshing movement of bevel gear 1 13 and bevel gear 2 14 can adjust the horizontal rotation angle of the camera 7 .

[0050] In this embodiment, the bolt fastener 1 3 , the bolt fastener 2 4 and the bolt fastener 3 43 are all composed of bolts and nuts, and the two semi-arc-shaped mounting plates 2 form a hollow circular mounting plate.

[0051] Bolt fasteners 3 fix the two semi-arc mounting plates 2.

[0052] It should be noted that the present invention is a refrigerant leakage monitoring device for refrigeration equipment. Before use, two semi-arc mounting plates 2 are fixed to the outside of the pipeline body 1 by bolt fasteners 1 3, and then the vertical rod 5 is connected to one of the semi-arc mounting plates 2 by bolt fasteners 2 4, and the camera 7 is turned on to achieve the working operating conditions. In addition, the camera 7 does not need to rotate in a large range, that is, the clockwise or counterclockwise rotation range of the movable rod 11 does not exceed ninety degrees;

[0053] The use angle of the camera 7 can be adjusted according to the use needs. When the horizontal direction of the camera 7 needs to be adjusted, the multi-stage electric telescopic rod 2 33 is started to act on the storage plate 34 to move to the predetermined position in the opposite direction of the vertical rod 5. At this time, the bevel gear 2 14 loses its restriction, and the multi-stage electric telescopic rod 18 is started to act on the fixed plate 19 to move. The fixed plate 19 moves with the motor 1 20, the linkage rod 21, the gear plate 3 22 and the gear plate 4 23 at the same time until they move to the predetermined position and stop. At this time, the gear plate 4 23 is meshed and connected with the gear plate 15, and the motor 120 is started to act on the linkage rod 21 to rotate, so that the gear plate 4 23 and the gear plate 15 are meshed and moved, and the gear plate 15 drives the bevel gear 2 14 to move synchronously, thereby driving the bevel gear 2 14 to mesh and move with the bevel gear 13. When the bevel gear 13 drives the camera 7 to rotate to the required angle, the motor 20 is stopped, and then the limit plate 2 35 is moved to the initial position by the multi-stage electric telescopic rod 2 33 to limit the bevel gear 2 14, so that the horizontal angle adjustment of the camera 7 can be completed;

[0054] During the process, when the fixed plate 19 moves, the spring 28 loses the restriction of the baffle plate 24 and rebounds with the limiting rod 26 toward the limiting plate 17. When the gear plate 4 23 and the gear plate 15 are meshed and connected, the limiting rod 26, under the action of the spring 28, inserts one end of the limiting rod 26 into the circular hole corresponding to the limiting plate 17, so that the limiting rod 26 cooperates with the limiting plate 17 to limit the movable rod 11 to prevent it from rotating.

[0055] When the camera 7 needs to be adjusted in the vertical direction, in the initial state of the device, that is, the limit plate 17 is not limited by the limit rod 26, the gear plate three 22 and the gear plate two 16 are meshed and connected, and the multi-stage electric telescopic rod two 33 is started to act on the storage plate 34 to move to the predetermined position in the opposite direction of the vertical rod 5. At this time, the bevel gear two 14 loses the restriction, and then the motor one 20 is started to act on the gear plate three 22 to rotate, so that the gear plate three 22 and the gear plate two 16 mesh and move, and then the gear plate two 16 rotates with the movable rod 11, and the rotation of the movable rod 11 rotates synchronously with the camera 7. When the camera 7 rotates to the required angle, the motor one 20 is stopped. At this time, the gear plate four 23 and the gear plate one 15 are meshed and connected through the multi-stage electric telescopic rod one 18, and then the angle of the camera 7 is adjusted through the motor one 20. When the camera is adjusted to the required angle, the storage plate 34 is moved to the initial position through the multi-stage electric telescopic rod two 33 to limit the bevel gear two 14.

[0056] When the camera 7 needs to be cleaned, in the initial state, the multi-stage electric telescopic rod 18 is started to make the gear plate 4 23 mesh with the gear plate 15, and then the multi-stage electric telescopic rod 2 33 is used to act on the storage plate 34 to move, so that the positions of the movable plate 37 and the camera 7 match and then stop. At this time, the movable rod 11 is limited by the limit rod 26, the bevel gear 2 14 is limited by the gear plate 4 23, and the cleaning brush plate 41 is moved out from the inner side of the protective cover 45, and the motor 2 38 is started to act on the movable plate 37 to rotate 180 degrees toward the front direction of the camera 7 and then stop. At this time, the brush of the cleaning brush plate 41 is in contact with the surface of the camera 7, and the motor 3 40 is started to act on the cleaning brush plate 41 to rotate for cleaning. After the cleaning is completed, the movable plate 37 is rotated 180 degrees in the opposite direction by the motor 2 38, and then the storage plate 34 is moved to the initial position by the multi-stage electric telescopic rod 2 33. At this time, the cleaning brush plate 41 is located on the inner side of the protective cover 45;

[0057] In addition, when the storage plate 34 moves, the storage plate 34 will move synchronously with the slide plate 31, and the hollow plate 30, the slide plate 31, the storage plate 34 and the second limiting plate 35 cooperate to limit and support the second bevel gear 14;

[0058] The camera 7 is an infrared gas leakage spectrum camera monitoring probe.
