Mechanical self-adaptive wind barrier for high-speed rail viaduct
The invention relates to the technical field of high-speed railways, and aims to solve the technical problems of poor reliability and high maintenance cost. In order to solve the technical problem, the invention provides the mechanical self-adaptive wind barrier for the high-speed rail viaduct. An auxiliary blade and a main blade are arranged at a preset included angle; the main blade is rotationally connected with the frame through a rotary connecting piece; one end of an elastic piece connected with the limiting assembly is connected with the frame, and the other end is connected to the back of the main blade; after the main blades bear the wind power, the main blades and the auxiliary blades rotate clockwise from the initial positions to reduce the wind power; along with continuous increase of wind power, the rotation angles of the main blades and the auxiliary blades are increased, so that the wind reduction rate is gradually increased; along with the continuous increase of the wind power, the main blades and the auxiliary blades continuously rotate clockwise until the main blades reach the maximum opening degree, so that the wind reduction rate is gradually reduced; and the first limiting piece limits the main blade to continuously rotate so as to discharge air. No electrical part exists, and the reliability of the wind barrier is greatly improved.
本发明涉及高速铁路技术领域，本发明要解决的技术问题是可靠性差，维护成本高。为了解决上述技术问题，本发明提供了一种高铁高架桥机械式自适应风屏障。本发明包括：副叶片与主叶片呈预定夹角设置；主叶片通过转动连接件与框架转动连接；连接限位组件的弹性件的一端与框架连接、另一端连接在主叶片的背面；主叶片或承受风力后，主叶片和副叶片自初始位置顺时针旋转进行减风；随着风力的不断增加，主叶片和副叶片旋转角度增加从而逐渐增大减风率；继续随着风力的不断增加，主叶片和副叶片继续顺时针旋转直至主叶片达到最大开度，使得减风率逐渐降低；第一限位件限制主叶片继续旋转，从而进行卸风。本发明不存在电气件，极大提高了风屏障的可靠性。
