The substation room has high requirements on temperature and humidity. In order to monitor the temperature and humidity of the high-voltage and low-voltage distribution devices in the substation room in real time, temperature and humidity monitoring devices are generally installed to monitor the temperature and humidity in the room in real time.

When the temperature and humidity monitor needs to be replaced, it is difficult for maintenance personnel to remove the temperature and humidity monitor from the mobile mechanism, which affects the work efficiency of replacing the temperature and humidity monitor. In view of this, the present utility model is specially proposed. Utility Model Content

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0023] The moving mechanism includes a fixed frame 1, two groups of electric telescopic rods 103 are symmetrically arranged at the lower end of the fixed frame 1, a first motor 2 is symmetrically arranged on the fixed frame 1, and a moving groove is symmetrically opened on the fixed frame 1, a first screw rod 201 is rotatably connected in the moving groove, the two first screw rods 201 are respectively fixedly connected to the output end of the first motor 2 on the same side, a first moving block 3 is threadedly connected on the first screw rod 201, and a second screw rod 5 is rotatably connected between the two first moving blocks 3, one of the first moving blocks 3 is fixedly connected to a support plate 702, a side of the support plate 702 away from the second screw rod 5 is fixedly connected to the second motor 7, the output end of the second motor 7 is fixedly connected to a second gear 701, the second gear 701 is located on the side of the support plate 702 away from the second motor 7, a first gear 501 meshing with the second gear 701 is fixedly connected to the second screw rod 5, the second screw rod 5 is threadedly connected to the second moving block 4, a limiting rod 301 is arranged between the two first moving blocks 3, and the limiting rod 301 is slidably connected to the second moving block 4.

[0024] When a temperature and humidity monitoring device is needed to monitor the temperature and humidity in the transformer and distribution room, the device is placed in the transformer and distribution room, and then according to the space size of the transformer and distribution room, the electric telescopic rod 103 is extended to drive the fixed frame 1 to rise, and then the first motor 2 and the second motor 7 work to make the temperature and humidity monitor 6 in a suitable position for detection.
