Anti-scouring device for offshore wind power pile foundation, offshore wind power pile foundation and offshore wind power equipment
The invention provides an offshore wind power pile foundation anti-scour device, an offshore wind power pile foundation and offshore wind power equipment, the offshore wind power pile foundation anti-scour device comprises a flow guide body and a rotary connecting piece, the flow guide body is rotationally connected with a pile barrel of the offshore wind power pile foundation through the rotary connecting piece, and the rotating axis is collinear with the axis of the pile barrel. For water flow in the incoming flow direction, part of the water flow flows out from the rear flow guide hole through the front flow guide hole and the flow guide channel of the flow guide body, and the situation that downflow generated by damming of the front side of the pile cylinder scours the mud surface of a seabed is avoided. Downward flow above the flow guide body passes through the first top flow guide hole and the flow guide channel and then flows out through the second top flow guide hole, and sediment on the rear side of the pile barrel is prevented from being scoured. For trailing vortex scouring on the rear side of the pile cylinder, due to the existence of the flow guide face of the flow guide body, trailing vortex scouring is hindered. And when the water flow pressures on the two sides of the flow guide body are unbalanced, the flow guide body rotates to change a local flow field and consume energy of water flows in different directions, so that the scouring degree to the pile cylinder is further reduced.
本发明提供一种海上风电桩基防冲刷装置、海上风电桩基和海上风电设备，包括导流体和转动连接件，导流体通过转动连接件与海上风电桩基的桩筒转动连接，转动轴线与桩筒的轴线共线。对于来流方向的水流，部分水流通过导流体的前部导流孔和导流通道从后部导流孔流出，避免了桩筒前侧壅水产生下降流冲刷海床的泥面。针对导流体上方的下降流，经第一顶部导流孔和导流通道后，经第二顶部导流孔流出，避免了对桩筒后侧的泥沙进行冲刷。对于桩筒后侧的尾涡冲刷，由于导流体的导流面的存在，阻碍了尾涡冲刷的进行。当导流体两侧水流压力不平衡时，导流体转动，进而改变局部流场，消耗不同方向水流的能量，从而进一步减小了对桩筒的冲刷程度。
