The left and right sides of the bottom plate 1 are respectively provided with 3 square through holes 24.

The working principle of the example is as follows:

the air pump 6 sends the air processed by the air filter 5 into the air heater 7, the heated dry hot air is sent into the air pipe 8, enters the exhaust pipe 9 at each position through the air pipe 8, and finally the hot air is sprayed out from the exhaust hole 10, so that the inside of the shell 2 is kept dry for a long time through continuously injecting the hot air, and the influence of the moisture on the electrical equipment is avoided. The air in the shell 2 can leave from the air holes 23, and the air pressure inside and outside the shell 2 is kept equivalent.

The number and position of the slide plates 17 can be adjusted by the worker according to the size of the electric equipment put in the housing 2. Due to the blocking of the limiting block 22, the sealing plate A20 and the sealing plate B21 cannot be turned inwards towards the large through hole 14 or the small through hole 15 but can be turned outwards. At the square through hole 11 through which the lead wire is required to pass, the worker inserts the movable plate 13 between the clips 12 in such a manner that the sealing plate a20 and the sealing plate B21 face the square through hole 11, and then the lead wire can be connected to the electric device in the housing 2 after being inserted into the large through hole 14 and the small through hole 15 from the outside. When the movable plate 13 is turned over and inserted between the clips 12 at a position where the lead wire is not needed, the sealing plate a20 and the sealing plate B21 can be pushed outwards by the air in the housing 2 to serve as an additional ventilation channel.

When the transfer is needed, the worker presses the movable rod 31 at each position down to the transverse through hole 27 at the upper position to align the socket A28 and the socket B29, inserts the fixed rod 30, fixes the position of the movable rod 31, the universal wheels 26 are exposed, and the worker can push the device to move to the designated position. When the user moves to the destination, the worker pulls out the fixed lever 30, and then raises the movable lever 31 to align the lower transverse through hole 27 with the socket a28 and the socket B29, inserts the fixed lever 30, and fixes the position of the movable lever 31, and at this time, the universal wheels 26 are retracted and supported by the support plates 32 on both sides of the base plate 1. The limiting plate 25 is used for preventing the movable rod 31 from falling out of the square through hole 24 or preventing the bottom plate 1 from directly touching the universal wheel 26.

Transparent observation window 4 makes things convenient for the staff to look over the inside electrical equipment of casing 2, improves inspection efficiency.

The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
