Description

High-speed train with flexible splash-proof and anti-icing device Technical Field The invention relates to the technical field of rail transit, in particular to a high-speed train with a flexible splash-proof and ice-proof device. Background When a high-speed train runs on a snow-covered line in winter, the high-speed train is influenced by snow particles and the melting and icing of the snow particles on the surface of a bogie heating element, and serious snow icing phenomenon often exists in a bogie cabin. Under the influence of snow ice on the surface of the bogie, a large amount of ice layers are covered on the surface of the bogie, the bogie axle weight is obviously increased, and the running stability of the train is reduced. When the car body ice gradually develops to the bogie area and ice, the movement performance of the bogie of the train is seriously attenuated, and the running safety of the train is more likely to be endangered. It is found that snow particles melt into water in the bogie cabin and splash under high-speed rotation of high-speed rotating structures such as train wheel sets, brake shafts and the like, which is a main cause of snow and ice formation in the bogie cabin of the high-speed train. The existing bogie cabin of the high-speed train is mainly an open cabin body, snow melt water can directly splash in the cabin on a large scale, no splash-proof and anti-icing design aiming at a high-speed rotating structure of the bogie exists in the existing design, snow accumulation in the bogie cabin occurs frequently, and normal operation of the high-speed train in winter in alpine regions is seriously influenced.
