Anti-scour turbulent flow device for offshore wind power pile foundation
The invention discloses an ocean wind power pile foundation anti-scouring turbulent flow device which comprises two speed regulating mechanisms arranged close to the two sides of a pile body in the water flow direction correspondingly, and the two speed regulating mechanisms are connected through a synchronizing mechanism to form a turbulent flow mechanism. The speed adjusting mechanism comprises a rotating rod, a propeller used for adjusting the water flow speed is arranged on the rotating rod, and the propeller rotates through potential energy of water flow. The synchronizing mechanism comprises two transmission devices and a transmission rod, the two transmission devices are matched with the two rotating rods in a one-to-one mode, the transmission rod is connected between the two transmission devices, the transmission rod is provided with an avoiding part used for avoiding the pile body, and the rotating rods, the transmission devices and the transmission rod are rotationally erected on the seabed through supports; the transmission rod can move back and forth on the support in the length direction. From the perspective of water flow power, the strength of water flow impact directly borne by the pile body is reduced through the arrangement of the turbulent flow device, and then the influence of tidal current on pile foundation scouring is reduced.
本发明公开一种海洋风电桩基防冲刷扰流装置，包括两个沿水流方向分别靠近桩身两侧布置的调速机构，两个所述调速机构之间通过同步机构连接以形成扰流机构；所述调速机构包括转动杆，所述转动杆上设有用于调节水流速度的螺旋桨，且螺旋桨通过水流的势能转动；所述同步机构包括分别与两根所述转动杆一一配合的两个传动装置，以及连接在两个所述传动装置之间的传动杆，所述传动杆上具有用于避开所述桩身的避让部，所述转动杆、传动装置和传动杆均通过支架可转动的架设在海底，且传动杆在所述支架上还可沿长度方向往返移动。本发明从水流动力角度出发，通过扰流装置的布置来减少桩身直接受到的水流冲击的强度，进而降低潮流对桩基冲刷的影响。
