An adjusting component for adjusting the height of different electronic components is slidably connected to the inner wall of the cabinet body 100. The ventilation slot 101 can be closed according to different environments through the first sealing plate 104 and the second sealing plate 105, so as to reduce the entry of water vapor into the cabinet body 100 and damage the electrical equipment, and it is convenient to extend the service life of the electrical equipment.

[0026] As Figures 1-5 shown, as a preferred implementation manner, on the basis of the above manner, further, a disassembly slot 110 is provided on the inner wall of the cabinet body 100. A filter plate 111 is slidably connected to the inner wall of the disassembly slot 110. Fixing bolts 112 for fixing the filter plate 111 are threadedly connected to the inner wall of the disassembly slot 110. Two groups of fixing bolts 112 are symmetrically arranged with respect to the central axis of the disassembly slot 110. By providing the fixing bolts 112, the convenience of disassembling the filter plate 111 can be improved.

[0027] As Figures 1-2As shown, as a preferred embodiment, on the basis of the above method, further, the adjusting member includes a bolt rod 120 fixedly connected to the inner wall of the cabinet 100. There are two groups of bolt rods 120 symmetrically arranged about the central axis of the cabinet 100.

The support plates 122 can slide to facilitate adapting to electrical equipment of different sizes, and the applicability is stronger.

[0028] As Figures 1-5 shown, as a preferred embodiment, on the basis of the above method, further, a height-adjusting nut 123 is rotatably connected to the bottom wall of the support plate 122. The height-adjusting nut 123 is threadedly connected to the bolt rod 120. A humidity detector 124 is fixedly connected to the inner wall of the cabinet 100. The stability of the support plate 122 when supporting electrical equipment can be improved through the height-adjusting nut 123.

When in normal use, start the cooling fan 131 to dissipate heat from the electrical equipment inside the cabinet body 100. When encountering rainy weather, start the servo motor 108 to drive the gear 109 to rotate. The movement of the first sealing plate 104 and the second sealing plate 105 is realized by the engagement of the gear 109 with the first toothed plate 106 and the second toothed plate 107. By the first sealing plate 104 and the second sealing plate 105 being in contact with each other, the closing of the ventilation groove 101 is realized, thereby reducing the entry of rainwater and moisture into the cabinet body 100. At the same time, the humidity detector 124 is used to judge the humidity degree inside the cabinet body 100. At the same time, when the electrical equipment is running, heat will be generated, and the wet air inside can be evaporated under the action of the heat, so as to keep the inside of the cabinet body 100 in a dry state, improve the service life of the electrical equipment, and have stronger practicability. When it is necessary to clean the filter plate 111, turn the fixing bolt 112 out of the cabinet body 100, so as to release the limit on the filter plate 111, and then slide the filter plate 111 out of the disassembly groove 110, realizing the convenience of cleaning the filter plate 111.
