Rainproof and dustproof box body structure

Abstract

The invention discloses a rainproof and dustproof box body structure, and particularly relates to the technical field of box body structures. The rainproof and dustproof box body structure comprises abox shell, two box side plates, a top side plate and a connecting plate, wherein the two box side plates are symmetrically and seamlessly welded to the left end and the right end of the box shell. External air can be sucked into an air duct through an air inlet by means of a fan, rainwater dropping from top to bottom can be prevented from entering the air duct through a rain baffle at the moment,water drops sucked into the air duct through the air inlet collide with the inner wall of the air duct, dust in the air can be filtered out by a filter screen at the same time, so that water drops and dust can fall down and flow out to an outflow port along the inclination of the bottom of the air duct. In this way, rainwater and dust are prevented from entering the box shell while heat dissipation is conducted in the box shell, so that the rainproof and dustproof effects of the box shell are achieved, and the problems that rainwater easily enters a box body through a heat dissipation channelin rainy days and dust easily enters the box body through the heat dissipation channel in an existing box body structure are solved.

Description

technical field [0001] The invention relates to the technical field of box structures, in particular to a rainproof and dustproof box structure. Background technique [0002] The box body is generally used as a carrier for some electronic accessories, such as a distribution box. Generally, switchgear, measuring instruments, protective appliances and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on a screen, because the box body is generally installed It is outdoors, so the rain and dust resistance of the entire box structure is very important. The current box structure, when installed outdoors, generally opens cooling channels on the front or side of the box to ensure heat dissipation, so that rainwater can easily enter the box through the cooling channels in rainy days, and dust can also easily enter through the cooling channels box, resulting in a short-circuit failure of the electronic components inside the box.
