Combined type offshore wind power foundation anti-scour device
The invention discloses a combined offshore wind power foundation anti-scour device which comprises a pile foundation, a plurality of turbulent flow ribs and a riprap layer, the multiple turbulent flow ribs are arranged around the pile foundation at intervals, one end of each turbulent flow rib is connected with the peripheral face of the pile foundation, the other end of each turbulent flow rib extends in the direction away from the pile foundation, the extension length of each turbulent flow rib ranges from 0.1 D to 0.67 D, and the riprap layer is arranged on the pile foundation. The plane where the turbulent flow ribs are located is perpendicular to the seabed surface, the vertical height is larger than or equal to 0.2 D, at least one part of the turbulent flow ribs are located on the seabed surface, D is the outer diameter of the pile foundation, and the riprap layer is located on the outer sides of the turbulent flow ribs and is laid on the seabed around the pile foundation and the turbulent flow ribs. The combined type offshore wind power foundation anti-scour device is provided with an active anti-scour structure and a passive anti-scour structure, so that the active anti-scour effect and the passive anti-scour effect are combined, the seabed around the pile foundation is effectively protected, and the combined type offshore wind power foundation anti-scour device further has the advantages of being simple in structure, easy to install, remarkable in effect and low in cost.
本发明公开了一种组合式海上风电基础防冲刷装置，包括桩基础、多个扰流肋条和抛石层，多个扰流肋条围绕桩基础间隔设置，扰流肋条的一端与桩基础的外周面相连，另一端向远离桩基础的方向延伸，扰流肋条的延伸长度为0.1D‑0.67D，扰流肋条所在平面与海床面垂直，竖直高度大于等于0.2D，且扰流肋条至少一部分位于海床面之上，其中D为桩基础的外径，抛石层位于扰流肋条的外侧，并围绕桩基础和扰流肋条铺设在海床上。本发明提供的组合式海上风电基础防冲刷装置具有主动防冲刷结构和被动防冲刷结构，因此结合了主动和被动两种防冲刷效果，对桩基础周围的海床起到有效的防护作用，还具有结构简单、易安装、效果显著、成本低的特点。
