Railway train ventilation component and ventilation device with dustproof function

Abstract

FThe invention provides a railway train ventilation component and a ventilation device with a dustproof function. A main body is included, the inner wall of the main body is provided with an air interchanger, the air interchanger is fixedly provided with a mounting bracket, the mounting bracket is provided with a ventilation fan, the inner wall of the main body is provided with a fixed shell, and a connecting spring is mounted in the fixed shell. According to the railway train ventilation component and the ventilation device with the dustproof function, when ventilation is finished, the ventilation fan in the air interchanger stops running, the connecting spring pushes a movable rod to return to the initial position through a compressed elastic force, and therefore a movable pull rod is promoted to drive dustproof baffles to be in a closed state; and through closing of the dustproof baffles, external dust and sundries are effectively prevented from entering so that the dust and the sundries are effectively prevented from remaining in the device to affect normal use of the device, and the device achieves the effect of automatic dust prevention when air exchange is not needed.

Description

technical field [0001] The invention belongs to the technical field of railway components, and in particular relates to a ventilation device which is a ventilation component of a railway train and has a dustproof function. Background technique [0002] With the construction of new urbanization in my country, especially the rise of metropolises and group cities, urban railways are showing a momentum of rapid development. At present, many cities in China are planning urban railways. The technology of urban trains is based on high-speed EMU technology and A-type car subways. Vehicles and technology. When the design speed of urban trains reaches about 160km / h, the vehicles must be equipped with traction motor cooling and ventilation devices. [0003] Nowadays, a railway train is a relatively dense and closed space with a relatively dense flow of people. It is easy to cause serious internal air pollution for a long time, especially in densely populated places on the train due to p...

Problems solved by technology

[0003] Nowadays, a railway train is a relatively crowded and closed space, which can easily lead to serious internal air pollution for a long time, especially in crowded places on the train due to poor air circulation, resulting in unpleasant smells, coupled with closed train compartments The space will also generate carbon monoxide, which requires regular ventilation, and because the traditional ventilation device is always open to the outside world, long-term use will easily cause dust and debris from the outside to enter the device, thereby causing damage to it. damage, which affects its service life, so it cannot meet the needs of users. Therefore, it is necessary to further improve
