Intelligent wind barrier for high-speed railway bridge and control method of intelligent wind barrier
The invention relates to an intelligent wind barrier for a high-speed railway bridge and a control method of the intelligent wind barrier. The wind barrier comprises a plurality of supporting stand columns on the two sides of the bridge, and a wind barrier assembly is arranged between every two adjacent supporting stand columns located on the same side; the air barrier assembly comprises a porous air barrier plate provided with a round hole and a fan arranged in the round hole, the fan is coaxial with the round hole, the axis of the round hole is perpendicular to the porous air barrier plate, the fan is electrically connected with a controller and used for controlling the fan rotating speed of the fan, and the controller is electrically connected with an air speed sensor. The wind barrier can control the rotating speed of the fan according to different wind speeds, self-adaptive adjustment of the ventilation rate is achieved, the wind barrier can also be used for controlling forward and reverse rotation of the fan, active flow control is achieved, the wind-induced vibration response of a bridge is reduced, wind power generation and active flow control can be combined with a traditional wind barrier, and the service life of the wind barrier is prolonged. The device is suitable for railroad bridges in remote mountainous areas where power supply is difficult and strong crosswind easily occurs, and the purposes of train and bridge protection and energy recovery are achieved.
本申请涉及一种用于高速铁路桥梁的智能风屏障及智能风屏障的控制方法，风屏障包括桥梁两侧的若干支撑立柱，位于同一侧的相邻的两个支撑立柱之间设有风屏障组件，风屏障组件包括开设有圆孔的多孔风障板以及设置在圆孔内的风机，风机与圆孔同轴，圆孔的轴线与多孔风障板垂直，风机电连接有控制器，用于控制风机的风机转速，控制器电连接有风速传感器。本申请能够根据不同风速控制风机的转速，实现透风率的自适应调节，还可用于控制风机的正、反转，实现主动流动控制，减小桥梁风致振动响应，能够将风力发电、主动流动控制与传统风屏障相结合，适用于电力供应困难且易出现强烈横风的偏远山区铁路桥梁，达到列车和桥梁防护以及能量回收的目的。
