A dust-proof and heat-dissipating power box

Abstract

The application provides a dust-proof and heat-dissipating power box, which relates to the technical field of power boxes, and includes a box body. The adjacent two sides of the box body are open and equipped with sealing mechanisms. The side walls of the box body The interlayer is arranged on the top, and each interlayer communicates with each other. The inner wall of the box is provided with air holes communicating with the interlayer. The sealing mechanism includes a connecting shaft and a switch door. The connecting shaft is vertically arranged at the corner of the box, at the top Penetrating through the box body upwards, the connecting shaft is a hollow structure, and several first air holes are opened on the shell of the connecting shaft, the top end of the connecting shaft is opened, and an end cover is installed, and the bottom of the end cover is provided with a Regulating mechanism. The power box proposed by the present invention is open on both sides, and a sealing mechanism that is easy to disassemble is installed at the opening. The sealing mechanism and the inside of the power box are connected, so that it is convenient to perform sufficient and uniform dust removal and heat dissipation treatment on the inside of the box, and improve The working performance of the power box.

Description

technical field [0001] The present application relates to the technical field of power boxes, in particular, to a dust-proof and heat-dissipating power box. Background technique [0002] At present, in the prior art, the power box is mainly used for the installation and protection of electrical components. With the construction of public facilities and power grid systems in the country, the use is becoming more and more common. During the use of the power box, the electrical components such as electrical switches and meters inside will generate heat under long-term working conditions. In order to effectively evacuate the heat inside the box, ventilators are generally provided on the side walls of the power metering box. Structure, in order to achieve the ventilation effect inside the box, so as to ensure the normal operation and performance of electrical components, but after the ventilation structure is installed on the side wall, it will inevitably cause the external dust ...

Problems solved by technology

During the use of the power box, the electrical components such as electrical switches and meters inside will generate heat under long-term working conditions. In order to effectively evacuate the heat inside the box, ventilators are generally provided on the side walls of the power metering box. Structure, in order to achieve the ventilation effect inside the box, so as to ensure the normal operation and performance of electrical components, but after the ventilation structure is installed on the side wall, it will inevitably cause the external dust to enter the inside of the metering box together with the air, so that it can touch the metering The electrical components in the box shorten the service life of the electrical components, which may lead to reduced insulation, short circuit and electric shock for a long time, and there are potential safety hazards;

[0003] In addition, the existing ventilation structure is passive ventilation. Ventilation can only be realized when there is air flowing outside the metering box. The heat dissipation effect of the metering box has a great relationship with the flow rate of the air; The heat dissipation effect is poor, which is easy to cause safety accidents such as fire. At the same time, only one side of the existing power box has a switch door. When installing the internal electrical components, it is not easy to operate, which also brings inconvenience to the construction.
