Alternating-current distribution box based on wind power opening and closing heat dissipation

Abstract

The invention provides an alternating current distribution box based on wind power opening and closing heat dissipation. The alternating current distribution box comprises a box body, wherein a filterscreen is fixed at the bottom of a rotating shaft, a shifting plate is fixedly connected above the right side of the rotating shaft, a movable plate is movably hinged to the upper end of the shiftingplate, an air cylinder is fixedly installed above the inner right wall of the box body, a wind wheel is fixedly installed at the top of a rotating column, a gear is fixedly connected to the bottom ofthe rotating column, a rack plate meshed with the gear is fixedly connected to the left end of the air cylinder, and a push plate corresponding to the movable plate is fixedly connected to the bottomof the rack plate. According to the invention, the filter screen is arranged to dissipate heat, the wind wheel is arranged to receive wind energy to rotate, the wind wheel drives the rack plate to rotate through the rotating column, when the teeth on the gear make contact with the rack plate, the rack plate is driven to move rightwards, the rack plate compresses and inflates the air cylinder, airis sprayed out towards the lower left portion through the nozzle, heat dissipation and blowing cleaning are conducted on components in the box body, and the problem that faults are prone to occurringafter dust is accumulated on the components is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of AC distribution boxes, in particular to an AC distribution box based on wind force opening and closing for heat dissipation. Background technique [0002] Since a large number of power and communication equipment, circuit breakers, frequency converters and other components are installed inside the power distribution cabinet, when the outdoor temperature is too high and a large amount of heat is generated during its own operation, the internal temperature of the power distribution cabinet will rise. , When the internal temperature of the power distribution cabinet is too high, it will affect the stability and service life of its operation, and in severe cases, it will cause the components to burn out and cause other accidents. [0003] Under normal circumstances, heat dissipation holes are installed on the power distribution cabinet for heat dissipation and cooling. However, these heat dissipation holes ha...

Problems solved by technology

[0002] Since there are a large number of components such as power and communication equipment, circuit breakers, and frequency converters installed inside the power distribution cabinet, when the outdoor temperature is too high, and a large amount of heat generated during its own operation, the internal temperature of the power distribution cabinet will rise. , When the internal temperature of the power distribution cabinet is too high, it will affect its operation stability and service life. In severe cases, it will also cause components to burn out and cause other accidents.

[0003] In general, cooling holes are installed on the power distribution cabinet for heat dissipation and cooling. However, the structure of these cooling holes is simple, and foreign dust and other sundries will also enter the cabinet, causing the surface of components to stick due to electrostatic adsorption and other effects. A large amount of dust is attached to it, which will corrode the components after accumulating over time, and also affect the heat dissipation effect of the components, affecting the normal operation of the power distribution cabinet
