[0003] When heat dissipation is performed inside a low-voltage distribution cabinet, dust easily accumulates on the mesh plate of the cabinet's heat dissipation port.

According to the relationship between humidity and temperature, when the temperature is high, the air has a stronger ability to hold water vapor, and water vapor is not easy to condense on the surface of the desiccant, so the side close to the cabinet is relatively dry. On the side close to the ground, due to the relatively low temperature, the air has a weaker ability to hold water vapor, and water vapor is more likely to be adsorbed or condensed on the surface of the desiccant, making this side relatively humid. When the temperature inside the cabinet is high, the limit block can be pushed to move to the side away from the cabinet door, so that the limit block drives the rack to move on the inner side of the connecting plate and the limit groove. Since the rack meshes and rotates with the gear, the gear rotates following the movement of the rack, so that the gear drives the drying box through the connecting rod to turn it in the placement groove, thereby turning and drying the desiccant inside the drying box.

[0006] 2. The low-voltage distribution cabinet with moisture-proof and dust-removing structure is provided with a collection mechanism. Under the suction of the vacuum machine, the grabbing rod rotates in the inner cavity of the collection shell to grab the dust entering the collection shell, thereby preventing the dust from floating around in the collection shell or re-entering the distribution cabinet, further improving the efficiency and effect of dust collection, allowing the dust to be collected more concentratedly, and reducing the risk of dust contamination to the interior of the equipment.

[0007] 3. The low-voltage power distribution cabinet with moisture-proof and dust-removing structure is provided with a sliding mechanism. Due to the influence of internal heat distribution and environmental humidity during the operation of the power distribution cabinet, one side of the drying box will be dry and the other side will be wet. This design can dry the wet side by turning the drying box over, so as to better adapt to the complex humidity environment in the power distribution cabinet, effectively remove moisture in the cabinet, prevent damage to electrical equipment due to excessive humidity, and improve the safety and stability of the operation of the power distribution cabinet.

At the same time, magnets 436 are provided on both sides of the drying box 433. After the drying box 433 is turned over, the magnets 436 and the inner side of the sliding plate 431 are attracted to each other, thereby fixing the position of the drying box 433. When the temperature inside the power distribution cabinet is high, the limit block 424 can be automatically pushed to move the rack 425, thereby driving the gear 434 to rotate, so that the drying box 433 rotates in the sliding plate 431, thereby realizing the turning and drying of the desiccant; By arranging magnets 436 on both sides of the drying box 433, the drying box 433 can be attracted to the inner side of the sliding plate 431 after being turned over, thereby fixing the position of the drying box 433. This fixing method is simple and reliable, and can ensure that the drying box 433 remains stable after being turned over, preventing it from shaking or shifting at will, and ensuring that the drying box 433 can perform its drying function normally.
