With the cooperation of the flexible rack 42, the first gear 32, the second gear 33 and the gear rod 12, the monitoring device body 1 is driven to move upward or downward, thereby adjusting the height of the monitoring device body 1, so that the monitoring device body 1 is more flexible when monitoring tunnel fires.

[0028] Working principle:

[0029] When the user uses the monitoring device body 1 to monitor the fire in the tunnel, the user can adjust the height of the monitoring device body 1 according to different monitoring requirements. When adjusting the height of the monitoring device body 1, the motor 5 in the device can be driven by an infrared remote control device. The user can drive the motor 5 through the infrared device. The motor 5 starts to drive the threaded rod 51 to rotate forward or reversely. The rotation of the threaded rod 51 will drive the movable rod 4 to move through the thread groove 41. When the movable rod 4 moves, it will drive the flexible rack 42 to move. When the movable rod 4 moves downward, it will drive the flexible rack 42 to move downward and lengthen. The spring 43 drives the flexible rack 42 to move upward when the movable rod 4 moves upward. At this time, the spring 43 is in a rebound state. When the flexible rack 42 moves, it drives the first gear 32 to rotate. The rotation of the first gear 32 drives the cylindrical rod 31 to rotate. The rotation of the cylindrical rod 31 drives the second gear 33 to rotate. When the second gear 33 rotates forward or reversely, it drives the gear rod 12 to move. The gear rod 12 moves upward or downward to drive the T-shaped slider 11 to slide in the T-shaped slide groove 21. The sliding of the T-shaped slider 11 drives the monitoring device body 1 to move upward or downward, thereby controlling the monitoring device body 1. The height position can be adjusted. When the existing monitoring device body 1 monitors the tunnel fire, the monitoring device body 1 can realize multi-angle rotation monitoring through the pan / tilt device carried by the monitoring device body 1. However, the height position of the existing monitoring device body 1 is fixed, which is not convenient for adjusting the height. Therefore, it is not convenient to adjust it according to the actual monitoring needs during use, and its use has certain limitations. The device is provided with a flexible rack 42, a first gear 32, a second gear 33 and a gear rod 12, and when the height of the monitoring device body 1 needs to be adjusted, The user can start the motor 5 through the infrared device to drive the threaded rod 51 to rotate, and with the cooperation of the flexible rack 42, the first gear 32, the second gear 33 and the gear rod 12, drive the monitoring device body 1 to move upward or downward, so as to adjust the height of the monitoring device body 1, so that the monitoring device body 1 is more flexible when monitoring tunnel fires; and the device is provided with a rectangular enclosure 24, which can protect the adjustment mechanism in the device in the rectangular enclosure 24, so as to prevent the mechanism from being exposed to the outside and being severely eroded by dust or hit by falling objects, thereby ensuring the normal use of the mechanism and having a good protection effect.
