The invention relates to the technical field of rail transit, in particular to a one-way ventilation system driven by piston wind and a control method. The ventilation system involves a tunnel and a space chamber arranged next to the side of the tunnel, wherein a one-way ventilation device is arranged between the space chamber and the tunnel; and the one-way ventilation device comprises a turbineball formed by splicing a plurality of arc-shaped shutters, a central shaft is arranged at the center of the turbine ball, a neck pipe is arranged at the end part of the turbine ball, an inner cavityof the neck pipe is in communication with an inner cavity of the turbine ball and is further provided with an air valve, the air valve is used for enabling spaces on both sides of the inner cavity ofthe neck pipe to communicate with each other or to be blocked, and the arc-shaped shutters are arranged obliquely at a certain angle with respect to the central shaft. A high-speed running train generates horizontal wind force, the ventilation system generates a rotating moment under the action of the horizontal wind force and drives the turbine ball to rotate continuously, the rotating turbine ball performs axial gas suction from the other side of the neck pipe through the air valve, and gas is accelerated and pressurized and then discharged from wind holes between the arc-shaped shutters inthe radial direction, so that one-way ventilation of the ventilation system is realized.
本发明涉及轨道交通技术领域,具体涉及一种利用活塞风驱动的单向通风系统及控制方法,通风系统包括隧道和紧邻隧道旁侧布置的空间室,空间室与隧道之间布置有单向通风装置,单向通风装置包括由多片弧形百叶拼接形成涡轮球,涡轮球中心设有中心轴,涡轮球的端部设有颈管,且颈管的内腔与涡轮球的内腔相通,颈管的内腔还安装有风阀,该风阀用于连通或阻断颈管内腔两侧的空间,所述弧形百叶与中心轴呈一定角度倾斜布置,高速行驶列车产生水平风力,通风系统在水平风力作用下产生转动力矩并带动涡轮球连续转动,旋转的涡轮球经风阀从颈管的另一侧轴向吸气,气体加速并增压然后沿径向从弧形百叶之间的风孔排出,从而实现通风系统的单向通风。
