Offshore wind power foundation scouring protection device
The invention discloses an offshore wind power foundation scouring protection device. The offshore wind power foundation scouring protection device comprises a pile foundation and flow guide pile groups, and the flow guide pile groups are arranged in the upstream direction of the pile foundation and the downstream direction of the pile foundation in the tidal current direction correspondingly; and at least one flow guide pile in the flow guide pile groups is different from other flow guide piles in height so as to be used for forming turbulent flow steps disturbing the tidal current direction, and turbulent flow channels used for reducing the tidal current flow speed are formed between the corresponding turbulent flow steps. According to the offshore wind power foundation scouring protection device, the flow velocity of tidal current and scouring energy of the tidal current to a seabed around the pile can be reduced through the flow guide pile groups, scouring of the tidal current to a soil layer around the pile is reduced, and therefore the seabed around the pile is protected.
本申请公开了一种海上风电基础冲刷防护装置，包括桩基础和导流群桩，沿潮流方向在所述桩基础的上游方向和所述桩基础的下游分别布置有所述导流群桩；所述导流群桩中至少一个导流桩与其它导流桩的高度不同，以用于形成扰乱潮流方向的扰流阶梯，对应的所述扰流阶梯之间形成以用于降低潮流流速的扰流通道。上述结构中通过导流群桩能够降低潮流的流速和潮流对桩周海床的冲刷能量，降低潮流对桩周土层的冲刷，从而保护桩周海床。
