Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that "the wind pressure generated by the lateral wind of the subway running directly acts on the screen door, which will cause the airtightness of the screen door to deteriorate in the long run. Secondly, because the screen door is closed most of the time, The dust raised by the side wind will be adsorbed on the inner glass, causing troubles to the daily cleaning work of the screen door, and a self-cleaning device for subway screen doors is proposed

Abstract

The invention discloses a self-cleaning device for a subway shield door. The self-cleaning device comprises: a shield door body movably installed between an upper guide rail seat and a lower guide rail seat; All are provided with a sealed chamber, an elastic airbag, the elastic airbag is located in the sealed chamber, the elastic airbag is cylindrical, a brush head mechanism, the brush head mechanism includes a brush plate, and the brush plate is fixed on the upper rail seat and the lower rail seat. Between the rail seats, a cavity is opened in the brush plate, and soft bristles are fixedly connected to one side of the brush plate. In the present invention, when the subway enters the platform, because the opening of the air intake pipe is parallel to the wind direction, the lateral wind is blown into the air intake pipe, and then the air flow is filled into the elastic airbag for storage, and the gas backflow is avoided by setting a one-way valve. Under the action of elasticity, the wind force is buffered, so as to reduce the direct impact of side wind on the screen door body and ensure the airtightness of the screen door body.

Description

A self-cleaning device for subway screen doors technical field [0001] The present invention relates to the technical field of subways, in particular to a self-cleaning device for subway screen doors. Background technique The subway is a kind of fast and large-scale transportation with electric traction that is gradually developed along the form of the ground railway system. Urban rail transit mode, its lines are usually laid in underground tunnels, and some are outside the city center, from underground to ground Or laying on a viaduct. When the subway enters the platform, it can drive the rapid flow of the airflow on both sides to generate lateral wind, and the generated wind pressure directly acts as a If the screen door is used for a long time, the sealing of the screen door will deteriorate, and secondly, the screen door is mostly closed. In this state, the dust raised by the lateral wind will be adsorbed on the inner glass, which will cause trouble to the daily...
