Distribution box with dustproof and heat-radiating function

Abstract

The invention discloses a distribution box with dustproof and heat-radiating function, which relates to the field of power devices. The distribution box comprises a box body. The left side of the topof the box body is fixedly connected with a cleaning device through a connecting block, and the left side of the top of the inner wall of the box body is fixedly connected with a spacing board, and the bottom of the spacing board is fixedly connected with the bottom of the inner wall of the box body. An air outlet device is fixedly connected to the right side face of the box body, and the cleanness of the air in an air bucket is guaranteed through the cleaning device, and the safety of the power distribution box is ensured, and the service lifetime of the power distribution box is prolonged. Through the cooperation of a vent pipe, a drying box, an exhaust fan, a drying box exhaust pipe and an air spray head, secondary dust removing and drying are conducted on the sucked air, so that the sucked air does not cause a short circuit. Through the arrangement of the air outlet device, when the temperature in winter is low, and the dustproof and heat-radiating function is not needed, a first cylinder and a second cylinder are in close contact, so that the air can enter into the interior part of the box body after being filtered by a second dustproof cloth, and the cleanness of the air entering into the box body is guaranteed.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a distribution box with dust-proof and heat-dissipating functions. Background technique [0002] The distribution box is a general circuit distribution box for all users to use electricity. With the development of electric power technology, the application of distribution box is more and more extensive. The distribution box can distribute electric energy reasonably, facilitate the opening and closing operation of the circuit, have a high level of safety protection, and can intuitively display the conduction of the circuit. state, easy to manage, and convenient for maintenance when a circuit failure occurs.

Problems solved by technology

[0003] During the use of the distribution box, the outdoor distribution box will be exposed to the sun and the internal components of the distribution box will heat up by themselves, which will cause the temperature inside the distribution box to rise. If the temperature is too high, there will be a greater safety hazard. At present, in order to dissipate heat inside the distribution box, heat dissipation holes are generally provided on the distribution box, through which the gas exchange between the distribution box and the outside world can be realized, so as to achieve the purpose of cooling inside the distribution box, and the dust will pass through the heat dissipation holes while dissipating heat Entering the components attached to the inside of the distribution box, on the one hand, dust adhesion will affect the normal heat dissipation of the components, and on the other hand, it will accelerate the aging of the components. Therefore, it is very necessary to install a dust-proof net. The long-term When used, more dust will be attached, which will block the mesh and affect the normal heat dissipation, and it needs to be cleaned regularly, which is time-consuming and labor-intensive.
