[0039] Working principle: In actual use, when the temperature of the cabinet 1 monitored by the temperature sensor 4 exceeds the temperature setting threshold, the electrically connected exhaust fan 19 controller 16 can be started to work, and the exhaust fan 19 will absorb the hot air inside the cabinet 1 and discharge it outside the cabinet 1. The controller 16 starts the air pump 15 to work. At this time, the air pump 15 will input the gas generated through the first air pipe 17 and the second air pipe 18 into the outlet pipe 12 when working, and the outlet pipe 12 will input the gas into the cabinet 1 through the air nozzle 13 set at the top. The gas above the cabinet 1 will be driven to the top by the input gas, so that the hot air in the cabinet 1 quickly moves to the exhaust fan 19 and is discharged from the cabinet 1 by the exhaust fan 19, so that the hot air in the cabinet 1 can be quickly replaced to cool it down, so that when the temperature of the cabinet 1 monitored by the temperature sensor 4 exceeds the temperature setting threshold, corresponding measures can be taken to cool it down, thereby avoiding excessive damage before the arrival of the staff;

[0040] When it is necessary to install the bottom plate 21 for placing electrical equipment in the cabinet 1, the staff inserts the limit block 34 into the limit groove 35 on the mounting plate 2, and then the staff moves it to the appropriate stop groove 36 according to the required installation position of the bottom plate 21. Then the staff can drive the rotating wheel 3 to cooperate with the two meshing bevel gears 31 to drive the screw rod 27 to rotate, so that the moving blocks 28 with threads at both ends of the screw rod 27 move toward each other at the same time, thereby pulling the moving rod 26 to move through the pull rod 29. When the two moving rods 26 move toward each other at the same time, the moving plate 24 is driven by the moving groove 25 to move. The rod 26 will drive the movable plate 24 to gradually move toward the mounting plate 2. At this time, the stop rod 37 fixed on the movable plate 24 will be correspondingly inserted into the stop groove 36, so that the installation between the base plate 21 and the mounting plate 2 is completed, which is convenient for the staff to install the base plate 21. At the same time, when the position needs to be adjusted again after installation, the rotating wheel 3 can be directly reversed to make the stop rod 37 disengage from the stop groove 36, so that the base plate 21 can move normally and adjust the position again. Through the above operation, the base plate 21 used to place the equipment can be easily installed and the overall position adjustment is also very convenient, which is convenient for the staff to operate.
