Abstract

The invention provides an anti-sand-wind ventilator and a railway train. The anti-sand-wind ventilator comprises an air duct, an exhaust fan, a ventilating cowl and a dust cap. The exhaust fan is arranged in the air duct, the ventilating cowl is fixed on the upper end portion of the air duct, a guide pillar is arranged in the inner side of the ventilating cowl, the dust cap is slidingly connected with the guide pillar, and the dust cap covers on an air outlet of the air duct via gravity when the exhaust fan is not in operation. The dust cap is arranged at the air outlet of the air duct and can automatically fall down to cover the air outlet of the air duct by gravity when the exhaust fan is not in operation, dust is avoided to be blown in the air duct through the lower portion of the ventilating cowl when the train is in operation, and dust prevention capacity of the anti-sand-wind ventilator is improved.

Description

technical field [0001] The invention relates to a railway locomotive, in particular to an anti-wind and sand ventilator and a railway train. Background technique [0002] At present, railway trains are the means of transportation that people often use for daily travel. Railway trains usually have a plurality of compartments connected together. The compartments are closed spaces, and the compartments are correspondingly equipped with ventilators. Exchange to ensure the air quality in the compartment. Ventilators in the prior art generally include a blower, an exhaust fan and a ventilation cap. The exhaust fan is arranged in the blower, and the end of the blower is provided with a blower. The blower is fixed on the compartment and communicates with the inside of the compartment. The fan realizes the exchange of the air in the compartment with the outside air, and the vent cap can effectively prevent rainwater from falling into the air duct. When the fan is not working, the s...
