Bionic deformable wind barrier for wind resistance of bridge structure and bridge crane
The invention provides a bionic deformable wind barrier for wind resistance of a bridge structure and a bridge crane. The bionic deformable wind barrier comprises a base, a flexible framework, a flexible panel and a rigid tip. A lower end of the flexible framework is connected with the base, and an upper end of the flexible framework is connected with the rigid tip; the flexible panel wraps an outer part of the flexible framework; and the flexible panel is provided with a ventilation pipe penetrating through a left side wall and a right side wall of the flexible panel. Under action of lateralwind, the wind barrier is passively deflected towards a leeward side so that aerodynamic configuration of the wind barrier and the aerodynamic configuration of a bridge structure are changed, flow guiding is achieved, and safety of a bridge is improved. And in a deformation process of the wind barrier, a ventilation rate of the wind barrier is always kept optimal so that the driving safety and comfort at different wind speeds are ensured. Therefore, the wind barrier provided by the invention can simultaneously guarantee the safety of the bridge structure and driving on the bridge under the action of strong crosswind.
本发明提供的一种用于桥梁结构和桥上行车抗风的仿生可变形风屏障，包括：底座、柔性骨架、柔性面板和刚性尖端；所述柔性骨架下端与所述底座连接，上端与所述刚性尖端连接；所述柔性面板包裹在所述柔性骨架的外部；所述柔性面板上设置有贯穿所述柔性面板的左右侧壁的透风管。在侧向风的作用下，本发明提供的风屏障被动的向背风一侧发生偏转，以此改变其自身和桥梁结构的气动外形，从而实现导流和改善桥梁的安全性；在风屏障变形的过程中，风屏障的透风率一直保持最优透风率，进而保证了不同风速下行车的安全性和舒适性。因此，本发明提供的风屏障能同时保障强侧风作用下桥梁结构和桥上行车的安全。
