Problems solved by technology

[0003] When the power distribution cabinet is used in rainy and snowy weather, it is easy to enter the inside of the power distribution cabinet due to the wind blowing rain and snow, especially the wind directly blows the heat dissipation holes of the power distribution cabinet, and the heat dissipation holes of the power distribution cabinet cannot be automatically opened and closed, nor can they be controlled The angle of the cooling holes makes it difficult to prevent the wind from blowing rain and snow into the power distribution cabinet. Therefore, we provide a device for power distribution cabinets that automatically changes the exhaust direction according to the wind direction to avoid direct blowing

Abstract

The invention relates to the technical field of intelligent power distribution cabinets, and discloses a device for automatically changing the exhaust direction according to the wind direction to avoid direct blowing for a power distribution cabinet, and the device comprises a steering mechanism. The surface of the steering mechanism is movably connected with a transmission mechanism, the surface of the transmission mechanism is movably connected with a trigger mechanism, and the surface of the trigger mechanism is movably connected with a shell. The surface of the transmission mechanism is movably connected with a pressurizing mechanism, an impeller and a lead screw are coaxially rotated by blowing the impeller, a threaded ring is driven to move inwards along the threaded ring and the lead screw, and the surface of a zigzag rod inclines inwards to push a push rod, so that a mounting barrel rotates. Vent holes in the surface of the mounting barrel and through holes in the surface of the shell are staggered, through the rotation of the mounting barrel, one end, close to the pull rod, of a flexible plate moves inwards, the other end, away from the pull rod, of the flexible plate is driven to move towards the inner wall of the shell, so that air pressure difference is generated between the interior of the mounting barrel and the end, away from the pull rod, of the flexible plate, and the heat dissipation effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of intelligent power distribution cabinets, in particular to a device for a power distribution cabinet that automatically changes the exhaust direction according to the wind direction to avoid direct blowing. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The 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. [0003] When the power distribution cabinet is used in rainy and snowy weather, it is easy to enter the inside of the power distribution cabinet due to the wind blowing rain and snow, especially the wind directly blows the heat dissipation holes of the power...
