Description
Technical Field
The utility model relates to a switch board design technical field specifically is a switch board ventilation duct structure.
Background
The power distribution cabinet is an indoor and outdoor combined electrical cabinet which protects the ground or a wall cable network or isolates the wall cable network in sections, has the function of protecting a cable network from being damaged by the external environment, and can reduce the floor area, reduce the manufacturing cost and enhance the reliability of power supply as a terminal control link of the cable network. The power distribution cabinet is used as main switch equipment of a cable network and is mainly used in industrial parks, residential communities, business centers and the like.
The heat radiation structure of current switch board sets up the ventilation duct usually on the lateral wall, but when rainy day, the existence in ventilation duct then can certainly lead to during the rainwater gets into the switch board to cause the influence to its inside, current switch board ventilation duct ventilation effect is poor moreover, if do the ventilation duct for rain-proofly for a short time, so the air permeability will reduce, thereby influence the heat dissipation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a switch board ventilation duct structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a switch board ventilation duct structure, includes: cabinet body curb plate, filter screen, pivot, rotor blade, rolling disc, fixed cover, connecting rod, pulling piece, internal thread post, variable speed motor, drive lead screw, cabinet body curb plate be the panel of switch board side, and open on the cabinet body curb plate and have inward ladder mouth, the filter screen setting on the bottom surface of cabinet body curb plate ladder mouth, the pivot both ends pass through copper sheathing swing joint in the both sides of cabinet body curb plate ladder mouth, the pivot evenly is provided with many, rotor blade rigid coupling in the pivot, the rolling disc rigid coupling in the one end of pivot, and the rolling disc is located the internal side of cabinet, pulling piece both ends connect on cabinet body curb plate through fixed cover, and the pulling piece is slidable in fixed cover, it has the bar mouth to open on the pulling piece, connecting rod one end connect on the rolling disc through round pin off-centre, other end swing joint is on the bar mouth of pulling piece, the internal thread column is fixedly connected to the upper end of the pulling piece, the driving screw rod is fixedly connected to an output shaft of the variable speed motor, and the driving screw rod is in threaded connection with the internal thread column.
