Power distribution cabinet with waterproof function

Abstract

The invention discloses a power distribution cabinet with a waterproof function, which comprises a power distribution cabinet body. The side wall of the power distribution cabinet body is provided with a first heat dissipation port, the first heat dissipation port is provided with a fixed block protruding outwards, the fixed block is provided with a second heat dissipation port, four edges of the fixed block are provided with flanges, and the flanges are covered with a rotating plate structure. A heat dissipation channel is formed among the flange, the rotating plate structure and the outer side wall of the power distribution cabinet body; rainwater flows along the flange and one end of the U-shaped rotating plate arranged below the fixed block. In a normal outdoor environment, heat in the power distribution cabinet body is discharged through the first heat dissipation opening, the second heat dissipation opening and the heat dissipation channel; when the rainwater is heavy, a motor drives an abutting plate to abut against a second heat dissipation opening to prevent the rainwater from entering the power distribution cabinet body, a U-shaped rotating plate is driven by a telescopic rod to rotate around a rotating shaft, the rainwater directly falls down through a gap between the abutting plate and the U-shaped rotating plate, and the situation that water is accumulated and enters the power distribution cabinet is avoided.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with a waterproof function. Background technique [0002] The power distribution cabinet is generally used in the occasions where the load is relatively scattered and there are few circuits. According to different usage scenarios, it is generally divided into outdoor power distribution cabinets and indoor power distribution cabinets. The outdoor power distribution cabinet itself has a certain heat dissipation performance. In the prior art, heat dissipation holes are generally provided on the power distribution cabinet to achieve heat dissipation. However, due to the large outdoor environmental factors of the outdoor power distribution cabinet, the rain will be heavy in rainy days, and the rain may enter the interior of the power distribution cabinet through the cooling holes, resulting in a serious short circuit in the internal ci...

Problems solved by technology

However, due to the large outdoor environmental factors of the outdoor power distribution cabinet, the rain may be heavy in rainy days, and the rain may enter the interior of the power distribution cabinet through the cooling holes, resulting in a serious short circuit in the internal circuit of the power distribution cabinet.

Moreover, the bottom of the existing outdoor power distribution cabinet is relatively low. Once there is water accumulation, the water overflows the bottom of the outdoor power distribution cabinet and there is a risk of water ingress
