The invention discloses a railway vehicle and a bogie snow accumulation prevention device thereof, the bogie snow accumulation prevention device comprises at least one drainage air duct, and the flow direction of airflow in all the drainage air ducts is opposite to the running direction of a vehicle body; each drainage air duct comprises a first air duct and at least one second air duct, and each second air duct is communicated with one end of the first air duct in a crossed manner; the first air duct is used for guiding airflow to flow through the bogie along the upper surface of the bogie and is provided with at least one air nozzle, and each air nozzle is used for spraying air to the bogie from top to bottom to melt ice and snow accumulated on the bogie; each second air duct is used for guiding airflow to flow from the end of the bogie to the bottom of the bogie so as to prevent accumulated snow from flowing into the bogie. According to the invention, airflow can be disturbed to flow into the bogie and ice and snow accumulated on the bogie can be melted in snowy weather, and the bogie can be cooled in high-temperature weather, so that adverse factors threatening the safe operation of the railway vehicle are reduced, and the running safety of the railway vehicle is improved.
本发明公开了一种轨道车辆及其转向架防积雪装置,转向架防积雪装置包括至少一条引流风道,全部引流风道内的气流流向与车体运行方向相反;每条引流风道包括第一风道和至少一条第二风道,每条第二风道与第一风道的一端交叉连通;第一风道用于引导气流沿转向架的上表面流过转向架,第一风道设有至少一个喷气口,每个喷气口用于自上而下向转向架喷气以融化转向架上堆积的冰雪;每条第二风道用于引导气流自转向架的端部流向其底部以干扰积雪流入转向架。本发明既能在大雪天气干扰气流流入转向架并同时融化转向架堆积的冰雪,又能在高温天气对转向架进行冷却降温,减少威胁轨道车辆安全运行的不利因素,提升轨道车辆的行车安全性。
