Description

Rail transit ventilation unit with dustproof function Technical Field The utility model relates to the technical field of ventilation equipment, in particular to a track traffic ventilation device with a dustproof function. Background Rail traffic refers to a type of vehicle or transportation system in which an operating vehicle needs to travel on a particular track. The rail transit wind well is an important guarantee for rail transit operation, provides necessary ventilation conditions for rail transit operation, and ensures safety and comfort of rail transit passengers. Most of the existing rail transit ventilation shafts are provided with dust blocking louvers at the ventilation openings to prevent dust, and although the dust blocking louvers can prevent dust to a certain extent, due to the fact that larger gaps are reserved between the louvers, part of dust in the air still possibly enters the ventilation shafts from the gaps, and therefore the existing rail transit ventilation devices are not good in dust prevention effect. Disclosure of utility model The utility model aims to provide a track traffic ventilation device with a dustproof function, so as to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a rail transit ventilation unit with dustproof function, includes cement bottom plate and air shaft, be provided with the air shaft with the interior intercommunication of rail transit station in the middle of the cement bottom plate, peg graft on the air shaft and be provided with the filter screen section of thick bamboo, install the base on the outside cement bottom plate of filter screen section of thick bamboo, install the protective housing on the base, the front of protective housing is the isosceles trapezoid shape of falling, the vent has been seted up to the both sides of protective housing, installs the dust guard on the vent, the protective housing top is provided with the upper cover, the upper cover four corners is provided with first screw, the upper cover passes through first screw and protective housing fixed connection, the motor is installed to the upper cover bottom, install the rocking arm on the output shaft of motor, the brush is installed to the free end of rocking arm, and the filter screen section of thick bamboo outer wall setting is hugged closely to the brush, the inside both sides that are provided with front drawer and back dust collection drawer respectively of base and the guide rail sliding connection of installing on the inner wall of base both sides. As a further scheme of the utility model, end covers are arranged at the outer ends of the front dust collection drawer and the rear dust collection drawer, second screws are arranged at four corners of the end covers, and the end covers are fixedly connected with the base through the second screws. As a still further proposal of the utility model, the dust baffle plates are arranged at equal intervals from top to bottom, and the side sections of the dust baffle plates are arc-shaped.
