Offshore wind power scour protection type foundation
The application discloses an offshore wind power scour protection type foundation which comprises a pile foundation and guide vane assemblies, wherein the guide vane assemblies are arranged on the upstream portion and the downstream portion of the pile foundation in the tidal current direction, so that secondary circulation can be generated around the guide vane assemblies through the guide vane assemblies by tidal current. Sediment at the roots of the guide vane assemblies is lifted through the secondary circulation to form a sediment-containing water flow, and buffer channels parallel to the tidal current direction are arranged in the guide vane assemblies, so that the sediment-containing water flow can form sediment on the seabed around the pile foundation through the buffer channels. The flow guide blade assemblies are arranged on the upstream and the downstream of the pile foundation correspondingly, the flow guide blade assemblies of the tidal current channel can excite secondary circulation, the secondary circulation guides the water flow with the large sand content close to the bottom into the buffer channel, the flow speed of the tidal current and the scouring energy of the tidal current on the seabed around the pile can be reduced, deposition of the sand-containing water flow is facilitated, and therefore, the seabed around the pile is protected.
本申请公开了一种海上风电冲刷防护式基础，包括桩基础和导流叶片组，沿潮流方向在桩基础的上游和桩基础的下游分别布置有导流叶片组，以便潮流通过导流叶片组在导流叶片组周围产生次生环流，次生环流将导流叶片组根部的泥沙掀起形成含沙水流，导流叶片组内设置有与潮流方向平行的缓冲通道，以便含沙水流通过缓冲通道在桩基础周围海床上形成淤积。通过在桩基础上游和下游分别布置导流叶片组，潮流通道导流叶片组可激发次生环流，次生环流将近底含沙量较大水流导入缓冲通道，能够降低潮流的流速和潮流对桩周海床的冲刷能量，有利于含沙水流的淤积，从而保护桩周海床。
