The invention discloses a high-speed train pantograph head sliding plate structure based on flow guiding and vortex breaking. A plurality of L-shaped flow channels which are used for shunting incoming flow and enabling shunted airflow to be ejected downwards are formed in the windward side of the structure at intervals in the length direction. The air flow ejected downwards from the L-shaped flow channel lifts the sliding plate to move upwards, so that the pantograph is in stable and reliable contact with the contact net. The pneumatic lifting force of the pantograph head can be increased, and the pneumatic resistance can be reduced, so that the pneumatic performance of the high-speed train pantograph is improved, the pantograph-catenary contact state is improved, and safe and efficient operation of a train is ensured.

    本发明公开了一种基于导流和破涡的高速列车弓头滑板结构,其迎风面上沿长度方向间隔开设有若干个用于对来流起到分流作用并使分流后气流向下方射出的L型流道,自L型流道向下射出的气流托举滑板上行使受电弓与接触网稳定可靠接触。本发明可实现弓头气动升力的增加和气动阻力的减小,从而提升高速列车受电弓气动性能,改善弓网接触状态,从而确保列车安全高效运行。
