Offshore pile foundation anti-scouring device, offshore wind power pile foundation and offshore wind power equipment
The invention provides an offshore pile foundation anti-scour device, an offshore wind power pile foundation and offshore wind power equipment. The offshore pile foundation anti-scour device comprises a rotary connecting piece, a flow guide assembly and a flow blocking plate. The flow guide assembly comprises a rotating body and a plurality of blades, the rotating body is connected with a pile barrel of the offshore pile foundation through a rotating connecting piece, the rotating axis and the axis of the pile barrel are collinear, and the blades are distributed in the circumferential direction of the rotating body. The two spoilers are arranged at the top and the bottom of the flow guide assembly respectively. Aiming at downflow in front of the pile, the spoiler at the top can effectively prevent the downflow from scouring the bottom layer of the sediment. For the incoming flow in front of the pile, due to the fact that the pressure of the blades on the two sides of the rotating body is unbalanced, the rotating body is driven to rotate under the condition of unbalanced reverse pressure, then the incoming flow is disturbed, ocean current energy is consumed, and the incoming flow in front of the pile is prevented from further forming downcomer scouring. And the spoiler at the bottom can greatly reduce sediment loss caused by sand carried by wake flow behind the pile, so that the degree of pile foundation scouring is further reduced.
本发明提供一种海上桩基防冲刷装置、海上风电桩基和海上风电设备，包括转动连接件、导流组件和阻流板。导流组件包括转动体和多个叶片，转动体通过转动连接件与海上桩基的桩筒连接，且转动轴线与桩筒的轴线共线，多个叶片沿转动体的周向分布。阻流板包括两个，分别设置在导流组件的顶部和底部。针对桩前下降流，顶部的阻流板可有效阻碍下降流对泥沙底层的冲刷。针对桩前来流，由于转动体两侧叶片的压力不平衡，在逆压不平衡情况下带动转动体进行转动，进而对来流进行扰动，从而消耗了海流能量，阻止了桩前来流进一步形成下降流冲刷。底部的阻流板可大幅减小桩后尾流携沙带来的泥沙损失，从而进一步减小了桩基冲刷的程度。
