Sandstorm-proof ventilation device for train

Abstract

The invention provides a sandstorm-proof ventilation device for a train. The device comprises a box body and an air conditioning unit. The air conditioning unit is fixedly mounted in the center of thebottom in the box body, a partition plate II is transversely and fixedly connected to the upper end of the air conditioning unit in the box body, and an air inlet pipe is transversely and fixedly mounted at the upper end of the partition plate II in the box body and is fixedly connected with an air supply outlet of the air conditioning unit; an air supply pipe assembly is fixedly installed at thebottom of the box body and located at the lower end of the water tank, a downcomer is fixedly installed between the water tank and the air supply pipe assembly, an air return pipe assembly is vertically and fixedly installed on the side, away from the air conditioning unit, of a partition plate I in the box body, and a dustproof cap is movably mounted at the bottom of the air return pipe assembly. Water pressers are fixedly mounted on the front side and the rear side of the air return pipe assembly in the box body, one end of a water outlet pipe of each water presser is fixedly connected withthe water tank, and a return pipe is fixedly connected between a water feeding pipe of each water presser and the air supply pipe assembly. The invention provides a sandstorm-proof ventilation devicefor a train, and aims to solve the problem of a poor sandstorm-proof effect of train ventilation equipment in the prior art.

Description

technical field [0001] The invention relates to the technical field of train ventilation equipment, in particular to a wind and sand prevention ventilation device for trains. Background technique [0002] At present, railway trains are the means of transportation that people often use for their daily travel. Railway trains usually have carriages connected by multiple sections. The carriages are closed spaces. External exchange to ensure the air quality in the compartment. [0003] For areas with a lot of sand and dust, sand and dust can easily enter the train compartment through air exchange. The air filter or filter element currently used is defective, and the sand and dust are easy to block, making the filter equipment unable to function, especially the installation and replacement at the bottom of the train. Air-conditioning equipment, in the process that the air-conditioning unit is not running, the exhaust pipe also easily enters sand and dust. Therefore, a kind of win...

[0003] For areas with a lot of sand and dust, sand and dust can easily enter the train compartment through air exchange. The air filter or filter element currently used is defective, and the sand and dust are easy to block, making the filter equipment unable to function, especially the installation and replacement at the bottom of the train. Air-conditioning equipment, when the air-conditioning unit is not running, the exhaust pipe is easy to enter sand and dust, therefore, a wind-sand-proof ventilation device for trains is proposed to solve the problem
