[0023] The working principle of a power system safe operation monitoring device provided by the present invention is as follows: First, start the second motor 92 according to requirements, so that the second threaded rod 93 rotates to drive the moving frame 72 to move upward. The upward movement of the moving frame 72 drives the monitoring device body 1 to move upward. In this case, the monitoring height can be adjusted. After adjustment, start the electromagnet 84 to adsorb the metal disk 86. After adsorption, the clamping rod 85 is moved away from the clamping groove 82. Then start the electric telescopic rod 74 to move the support disk 75 to squeeze the connecting block 71. After squeezing, the inclination angle of the connecting block 71 can be adjusted, so as to adjust the monitoring angle of the monitoring device body 1. After adjustment, under normal circumstances, the two baffles 42 will seal the air inlet barrel 21 and the air outlet pipe 31.

During the normal working process, the temperature sensor 14 will continuously detect the temperature inside the monitoring device body 1. When the temperature is too high, the external PLC controller will automatically control the first motor 64 to work, so that the first threaded rod 63 rotates. The rotation of the first threaded rod 63 drives the moving block 62 to move. The movement of the moving block 62 drives the gear 52 to rotate. The rotation of the gear 52 drives the rotating shaft 51 to rotate. The rotation of the rotating shaft 51 drives the two pull ropes 45 to move. The movement of the two pull ropes 45 drives the two baffles 42 to move. The movement of the two baffles 42 can open the air inlet barrel 21 and the air outlet pipe 31. In this case, heat dissipation can be carried out. During the heat dissipation process, the air extraction fan 32 can be started to extract the hot air inside the monitoring device body 1. During the air extraction process, external gas will enter the inside of the monitoring device body 1 through the air inlet barrel 21. At this time, the first filter screen 25 can effectively prevent external dust from entering. At the same time, the activated carbon 23 located inside the air inlet barrel 21 will adsorb the moisture in the gas entering the inside of the monitoring device body 1. After adsorption, water vapor can be prevented from entering the inside of the monitoring device body 1 and damaging the electrical components inside.
