Abstract

A railway vehicle and a device therefor for preventing accumulation of snow on a bogie. The device for preventing accumulation of snow on a bogie comprises at least one flow guide air duct (1), and the flow direction of an airflow in each flow guide air duct is opposite to a running direction of a vehicle body; each flow guide air duct comprises a first air duct (11) and at least one second air duct (12), each second air duct being in cross-communication with one end of the first air duct; the first air duct is configured to guide the airflow to flow through a bogie along an upper surface of the bogie (2), the first air duct is provided with at least one air ejection port (111), and each air ejection port is configured to eject air to the bogie from top to bottom to melt ice and snow accumulated on the bogie; and each second air duct is configured to guide the airflow to flow from an end portion of the bogie to the bottom of the bogie so as to avoid accumulated snow from flowing into the bogie. The device for preventing accumulation of snow on a bogie not only can avoid the airflow from flowing into the bogie in heavy-snow weather and melt ice and snow accumulated on the bogie at the same time, but can also cool the bogie in high-temperature weather, thereby reducing adverse factors that threaten safe running of a railway vehicle, and improving the driving safety of the railway vehicle.
