Outdoor rainproof distribution box efficient in heat dissipation

Abstract

The invention relates to an outdoor rainproof distribution box efficient in heat dissipation and relates to the technical field of distribution boxes. The distribution box comprises a box body and a cover body device. The box body is a rectangular parallelepiped with an opening at the top. The cover body device comprises a cover body and a triangular rainproof head cover fixed to the top of the cover body. The cover body is a rectangular parallelepiped with an opening at the bottom. The cover body and the box body are plugged to be used in combination. The inner walls on both sides of the box body are provided with concave chutes between which a component mounting plate is connected in a clearance fit way. The component mounting plate is provided with electrical components. Through-holes are uniformly distributed on the top wall of the cover body. Heat-dissipating holes are uniformly distributed on the plugged parts on both ends of the triangular rainproof head cover. The outdoor rainproof distribution box efficient in heat dissipation is simple in structure, reasonable in design, low in manufacturing cost, easy to operate, safe and reliable. The whole box is closed and only the top of the box is provided with the through holes for dissipating heat.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, and more specifically, relates to an outdoor distribution box for rainproofing and high-efficiency heat dissipation. Background technique [0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, constitutes low-voltage distribution equipment, can rely on manual or automatic switch during normal operation. Turn on or off the circuit, cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation, use the measuring instrument to display various parameters in operation, and adjust some electrical parameters to prompt or deviate from the normal working state Signaling, often used in various hair, distribution, and substations. Most of the existing distribution boxes need to be used outd...

AI Technical Summary

Problems solved by technology

Most of the existing distribution boxes need to be used outdoors. The box body of the distribution box is usually placed directly on the ground, and the front side wall of most distribution boxes is a box door as a whole. The ventilation and rainproof function is not good. In weather, rainwater is easy to infiltrate into the distribution box, causing short circuit and damage to the electrical components in the distribution box, affecting the normal use of the distribution box and not conducive to the discharge of rainwater. The temperature will gradually rise, and the heat dissipation performance is poor, so it is easy to damage the equipment in the box. Even if there are ventilation holes, the electrical appliances will be damaged. In addition, the components of the existing distribution box are fixed on the component board in the box. , and the component board is fixed in the box as a whole, so the components or the fixing plate of the components cannot be taken out as a whole during maintenance, which is very inconvenient for maintenance, and it is extremely inconvenient to take out the whole
