Sandstorm-preventive high-speed railway vehicle

The utility model relates to a sandstorm-preventive high-speed railway vehicle. The sandstorm-preventive high-speed railway vehicle comprises a vehicle body, a bogie, an equipment cabin, a pantograph and an overhead type air conditioning set. Apron plates, a bottom plate and a framework of the equipment cabin are in sealing connection with the vehicle body. The vehicle body, the bogie, the equipment cabin and the pantograph are coated with sandstorm-preventive coatings respectively. A plurality of spraying devices are mounted on the bogie, are connected with an air source through air supply pipelines and are used for spraying compressed air to a braking system and/or a rail in front of wheels. The sandstorm-preventive high-speed railway vehicle has the advantages that series of operation problems of existing motor train units in sandy areas and desert areas are analyzed, reasons for the problems are analyzed systematically, optimization and improvement schemes are put forward, overall sandstorm prevention performance of systems of the motor train units are optimized and improved, and the railway vehicle can meet requirements on operation in arctic-alpine high-temperature environments with large sandstorms.
