Power distribution cabinet with heat-dissipating and dust-preventing functions

Abstract

The invention relates to the technical field of electronics and discloses a power distribution cabinet with heat-dissipating and dust-preventing functions. The power distribution cabinet with the heat-dissipating and dust-preventing functions comprises a cabinet body and a base, wherein a waterproof hood is fixedly mounted on the top of the cabinet; a connecting block is fixedly mounted on the topend of the cabinet; a first motor is fixedly mounted on the lower surface of the connecting block; the output shaft of the first motor is fixedly connected to a rotating rod; one side of the rotatingrod is fixedly connected to a first bearing; a lead screw is movably connected in the first bearing; the bottom end of the lead screw is movably connected to a second bearing; a nut is in threaded connection to the lead screw; and the upper surface of the nut is fixedly connected to a connecting rod. According to the power distribution cabinet with the heat-dissipating and dust-preventing functions, by arranging the first motor, the lead screw, the nut, the connecting rod and the bearing, the first motor drives the lead screw to rotate to drive the nut on the lead screw to rotate so as to further drive the connecting rod to drive the nut on the lead screw to move up and down, so that a hairbrush driven by the first motor brushes down dust, with relatively small grain size, attached to a dustproof screen, and the dust enters a collecting box.

Description

technical field [0001] The invention relates to the technical field of electricity, in particular to a power distribution cabinet with heat dissipation and dustproof functions. Background technique [0002] Distribution cabinet, a box in which electrical appliances and their wiring are placed to distribute electrical energy. Collectively referred to as power distribution centers, they are centrally installed in substations of enterprises to distribute power to lower-level power distribution equipment in different locations; power distribution cabinets (boxes) are divided into power distribution cabinets (boxes) and lighting distribution cabinets (boxes), The metering cabinet (box) is the final equipment of the power distribution system. These devices need to dissipate heat, so there must be heat dissipation windows on the box body. In order to prevent dust and small animals from entering, dust-proof nets are pasted on the heat dissipation windows. , after a period of operat...
