Automatic dust removal device in electrical automation power distribution cabinet

Abstract

The invention discloses an automatic dust removal device in an electrical automation power distribution cabinet. The device comprises a power distribution cabinet, air blowing mechanisms are arrangedon two sides of the interior of the power distribution cabinet respectively; the air blowing mechanisms comprise fixed pieces, sliding rods, lead screws, movable pieces, air blowing covers and motors.The fixed pieces are installed at two ends of two sides of the interior of the power distribution cabinet respectively. The sliding rods are installed between the fixed pieces, the lead screws are movably installed on inner sides of the sliding rods between the fixed pieces through bearings, the movable pieces are movably installed on outer sides of the lead screws through threads, two ends of the movable pieces are arranged on outer sides of the sliding rods in a sleeving mode, and the air blowing covers are installed on the sides, away from the lead screws, of the movable pieces. A controlbox controls the air blowing mechanisms to blow air to the inner side of the power distribution cabinet, then dust deposited on components is excited, meanwhile, a dust suction mechanism is started through the control box to suck the excited dust to an inner side of a collection box, and then the automatic cleaning of the dust on the inner side of the power distribution cabinet is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical automation distribution cabinets, in particular to an automatic dust removal device inside the electrical automation distribution cabinet. Background technique [0002] Power distribution cabinets (boxes), power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes) are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The exis...

Problems solved by technology

This level of equipment should provide protection, monitoring and control for the load. The existing devices do not have the function of automatically going out of the city, resulting in a large amount of dust accumulated on the components in the power distribution cabinet, resulting in poor contact of the components, which in turn affects the operation of the device. At the same time, the top of the existing device does not have a city-out device, resulting in a large amount of dust accumulated on the top, so that the dust penetrates into the inner side of the power distribution cabinet, thereby affecting the operation of the device
