[0033] The first track 2 and the second track 3 are respectively provided with a first driving mechanism 9 and a second driving mechanism 10, which are used to drive the second track 3 and the platform frame 4 respectively; the second track 3 and the platform frame 4 can be driven by the first driving mechanism 9 and the second driving mechanism 10, so that the induced draft pump 5 can move freely on the inner wall of the box body 1, and the output end of the induced draft pump 5 can blow evenly and comprehensively toward the electrical equipment in the box body 1, thereby achieving the effect of efficient dehumidification and heat dissipation.

[0034] Specifically, the drying section 8 includes a drying box 801, which is fixed to the outer wall of the housing 1, and the air inlet 6 passes through the side wall of the drying box 801 and extends into the interior of the drying box 801.

[0035] Specifically, the first driving mechanism 9 and the second driving mechanism 10 are both configured as one of an electric push rod, a cylinder, a hydraulic cylinder and a servo motor driven screw rod structure.

[0036] Specifically, the input end of the induced draft pump 5 is connected to a bellows 11 , and the input end of the bellows 11 is installed in the air inlet 6 to facilitate adapting to the adjustment position of the induced draft pump 5 .

[0037] Specifically, the box body 1 includes a box frame 101 and a cover plate 102. The cover plate 102 is buckled into the top opening of the box frame 101.
