[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figures 1 to 6 The illustrated embodiment of a moisture-resistant power distribution cabinet for use in humid environments includes a cabinet 1. A cover plate 14 is fixedly attached to the top of the cabinet 1. The cover plate 14 is in a herringbone configuration and has a certain area to prevent rainwater from dripping directly onto the cabinet 1. The cabinet 1 is also provided with a door panel. A first square groove 2 is defined on the sidewall of the cabinet 1. The bottom of the first square groove 2 is tilted, with the end away from the square sleeve 6 tilted downward to facilitate the shedding of water droplets. Multiple first square grooves 2 are provided, equidistantly spaced. A first filter plate 3 is fixedly attached to each of the first square grooves 2. The first filter plate 3 filters dust and other impurities from the external air, preventing them from entering the cabinet 1. The cabinet 1 is provided with a square plate 4. Multiple second square grooves 5 are defined on the square plate 4, corresponding one-to-one with the first square grooves 2. A second filter plate 15 is fixedly attached to each of the second square grooves 5. The second filter plate 15 may be a sponge filter plate to prevent moisture from entering the cabinet 1. The second square groove 5 is connected to the corresponding first square groove 2 through a square sleeve 6, and the square sleeve 6 has a certain elasticity.

[0025] The cabinet 1 houses a control assembly that drives the square panel 4 up and down. The assembly includes a chute 8, a slide plate 9, a support plate 10, and an electric push rod 11. The chute 8 is located on the inner wall of the cabinet 1, and the slide plate 9 is slidably connected within the chute 8. The chute 8 and slide plate 9 form a T-shaped structure to enhance sliding stability. The support plate 10 is fixedly attached to the inner wall of the cabinet 1. One end of the electric push rod 11 is fixedly connected to the slide plate 9, while the other end is fixedly connected to the support plate 10.

[0026] When the telescopic end of the electric push rod 11 is retracted, the slide plate 9 drives the square plate 4 to move upward, so that the square sleeve 6 changes from a rectangular shape to an oblique parallelogram shape (refer to Figure 6 ), the gap in the square sleeve 6 is reduced; and when the telescopic end of the electric push rod 11 is extended, the square plate 4 is driven downward by the slide plate 9, so that the square sleeve 6 is changed from an oblique parallelogram to a rectangular shape, or it can be tilted downward. When the weather is good, the square sleeve 6 is in a matrix shape, having a larger ventilation area, which is convenient for ventilation and heat dissipation.

[0027] When the telescopic end of the electric push rod 11 is controlled to switch between retraction and extension, the wind direction is changed, the wind action area is expanded, and the heat dissipation effect is improved.

[0028] A drying component is provided inside the square sleeve 6, and the drying component includes a drying strip 7. There are multiple drying strips 7, which are fixedly connected to the inner wall of the square sleeve 6. The multiple drying strips 7 are distributed at equal distances. The drying strips 7 can be pressed together by a desiccant and have the effect of absorbing water vapor.

[0029] When it rains, the telescopic end of the electric push rod 11 is controlled to be retracted, and the square plate 4 is driven to move upward by the slide plate 9, so that the square sleeve 6 changes from a rectangular shape to an oblique parallelogram shape (refer to Figure 6 ), the gap in the square sleeve 6 is reduced, reducing the air inlet area, so that the gas can fully contact the drying strip 7. At the same time, the bottom end of the square sleeve 6 is inclined to facilitate the sliding of water droplets. At the same time, the drying strip 7 absorbs water vapor and, with the cooperation of the second filter plate 15, prevents water vapor from entering the interior of the cabinet 1.

[0030] In addition, the telescopic end of the electric push rod 11 can be controlled to switch between retraction and extension, so that the square sleeve 6 shakes, and the gas entering the square sleeve 6 fully contacts the drying strips 7, thereby improving the water vapor absorption effect.

[0031] And the drying strip 7 can be replaced regularly.

[0032] A circular groove 12 is provided on the side wall of the cabinet 1. The circular groove 12 is located on the side of the cabinet 1 away from the first square groove 2. An exhaust fan 13 is fixedly installed inside the circular groove 12. The exhaust fan 13 is provided with a built-in motor and other structures. When it is in operation, external air enters the interior of the cabinet 1 through the first square groove 2, the square sleeve 6 and the second square groove 5.
