Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to an outdoor rainproof power distribution cabinet. Background Technology
[0002] Existing power distribution cabinets have certain structural defects, resulting in problems with waterproofing, dustproofing, shielding, and heat dissipation to varying degrees. Most of them cannot simultaneously achieve these functions in a single box or cabinet. Furthermore, their IP rating does not reach IP56. In particular, rainproof cabinets with fans have fan holes on the side, allowing rainwater to seep into the cabinet. Some cabinets, in order to achieve a waterproof rating, do not have fan holes, which inevitably affects their heat dissipation. Over a long period of use, dust from the outside air can also enter the cabinet through the fan holes, resulting in the existing rainproof cabinets having weak dustproof capabilities and failing to meet the IP rating.

The fan cover includes a fan cover top cover, a fan cover left side panel, a fan cover right side panel, a fan cover door panel, a fan cover bottom panel, a hinge, and a door lock. A sealing strip is provided inside the fan cover door panel, and ventilation holes are opened in the fan cover bottom panel. The thickness of the fan cover top cover is greater than the thickness of the cover body composed of the fan cover left side panel, fan cover right side panel, fan cover door panel, and fan cover bottom panel, forming an eaves structure.
[0005] To further achieve the purpose of this utility model, the top cover of the fan hood may have a rear end that is bent downwards and folded, and a front end that is bent downwards, backwards, downwards, forwards, and then upwards continuously; the left and right side panels of the fan hood may have symmetrical and identical structures, with the top of the side panels extending forward to cooperate with the upper side of the top panel of the fan hood and seal the opening on the side of the top panel of the fan hood, and the rear part of the side panels being bent inwards and folded, and the front part being bent inwards, forwards, and then outwards continuously; the bottom panel of the fan hood may have a rear end that is bent upwards and folded, and the front end being bent upwards, forwards, and then downwards continuously; and all four sides of the fan hood door panel may have inward bending and folding.
[0006] To further achieve the purpose of this utility model, a screw for connecting the ground wire can be provided on each of the fan cover door panel and the left side panel of the fan cover.
[0007] Compared with existing products, this utility model has the following significant features and positive effects: This rainproof power distribution cabinet is composed of a cabinet body and a fan cover. The top cover, left side panel, right side panel, door panel, and bottom plate of the fan cover are first assembled and welded together. The left side panel of the fan cover is assembled with the left side panel of the fan cover via two sets of hinges. A door lock is added to the right side panel of the fan cover. A screw is added to both the door panel and the left side panel of the fan cover for connecting the ground wire. Finally, the entire assembly is welded to the fan hole on the left side of the cabinet body. While achieving heat dissipation for the power distribution cabinet, this significantly improves the rainproof and dustproof rating of the outdoor cabinet, enhances product quality, and increases product practicality. The design enhances the product's aesthetics and durability. The top cover of the fan hood is designed as a single-piece bent piece, with the connection to the door bent upwards to prevent rainwater from entering. The upper parts of the left and right side panels of the fan hood are welded to the top cover with a slope, allowing rainwater to slide off easily and preventing water accumulation. The left and right side panels of the fan hood are bent outwards at the connection to the door to prevent rainwater from entering. All four sides of the fan hood door panel are folded inwards, tightly interlocking with the bends of the top cover and the left and right sides. A sealing strip is added along the inner perimeter of the fan hood door panel to increase waterproofing and prevent rainwater from entering. The bottom plate of the fan hood has strip-shaped ventilation holes to achieve ventilation, air circulation, and heat dissipation. Attached Figure Description
