Dustproof electric cabinet

Abstract

The invention relates to a dustproof electric cabinet. The dustproof electric cabinet comprises a shell. Heat dissipation windows are formed in the sidewalls of the shell, and vertical dust screens are arranged in the shell and closely to the sidewalls. A water collecting hopper is arranged at the top of the shell, and the upper edges of the dust screens extend out of the top of the shell and are communicated with the bottom of the water collecting hopper. Dust discharge grooves are arranged at the bottom of the shell, and the lower edges of the dust screens extend out of the dust discharge grooves. Vertical driving shafts are arranged in the shell, the upper ends of the driving shafts penetrate through the top of the shell, and driving fans are fixedly mounted at the upper ends of the driving shafts. Friction plates are mounted on the side circumferential walls of the driving shafts, and the ends of the friction plates are in contact with the dust screens. The dustproof electric cabinet is capable of preventing dust efficiently on the premise of guaranteeing ventilation and heat dissipation, so that cleanliness and safety can be improved effectively and interior electric elements can be better protected.

Description

technical field [0001] The invention relates to a power device, in particular to a power cabinet. Background technique [0002] The power cabinet is a commonly used basic power equipment, which is equipped with a large number of power components; when the power cabinet is working, a large amount of heat is generated inside, therefore, the side wall of the power cabinet needs to be equipped with heat dissipation windows; Strip-shaped shutters, that is, a group of parallel strip-shaped holes are opened on each side wall, and the upper part of each strip-shaped hole has a strip-shaped eaves that are folded down and half surround the strip-shaped holes. Because the strip-shaped holes are used to block rainwater; although the strip-shaped windows are used to block rainwater by the strip-shaped eaves, the dust cannot be blocked by the strip-shaped eaves, and the dust is usually raised from the ground; therefore, it is very It is easy to enter the surrounding area of ​​the strip...

[0002] The power cabinet is a commonly used basic power equipment, which is equipped with a large number of power components; when the power cabinet is working, a large amount of heat is generated inside, therefore, the side wall of the power cabinet needs to be equipped with heat dissipation windows; Strip-shaped shutters, that is, a group of parallel strip-shaped holes are opened on each side wall, and the upper part of each strip-shaped hole has a strip-shaped eaves that are folded down and half surround the strip-shaped holes. Because the strip-shaped holes are used to block rainwater; although the strip-shaped windows are used to block rainwater by the strip-shaped eaves, the dust cannot be blocked by the strip-shaped eaves, and the dust is usually raised from the ground; therefore, it is very It is easy to enter the surrounding area of ​​the strip-shaped eaves, and then enter the strip-shaped holes; it can be considered that the setting of the strip-shaped eaves is more convenient for dust to enter the power cabinet; it will cause greater damage to the power components inside the power cabinet
