Anti-scouring offshore wind turbine foundation
The invention relates to an anti-scouring offshore wind turbine foundation. The anti-scouring offshore wind turbine foundation comprises a foundation body, an anti-scouring coating layer and an anti-scouring clamping ring, wherein the anti-scouring clamping ring is arranged on the foundation body in a sleeving mode, the anti-scouring clamping ring and the anti-scouring coating layer are arranged at an interval. The anti-scouring coating layer is arranged on the surface of a seabed in a covering mode, so that the protective effect on the seabed around the foundation body is achieved; further, when a water flow flows around the foundation body, the anti-scouring clamping ring can play a role in breaking a turbulent flow field and reducing shearing stress of the water flow around the foundation body, so that the scouring capability of the water flow is greatly weakened; on one hand, the scouring action of the water flow on the seabed can be weakened; and on the other hand, weakening of the water flow scouring capacity can further prevent the anti-scouring coating layer from being quickly scoured, so that the anti-scouring coating layer is kept for a long time, the continuous protective effect on the seabed is achieved, and therefore, the anti-scouring effect of the above anti-scouring offshore wind turbine foundation is good.
本发明涉及一种防冲刷的海上风机基础，包括基础本体、防冲刷覆层及防冲刷卡圈。防冲刷卡圈套设于基础本体上，并与防冲刷覆层间隔设置。防冲刷覆层覆设于海床的表面，从而对基础本体周围的海床起到防护作用。进一步的，水流在基础本体的周围流动时，防冲刷卡圈可起到破坏扰流流场、减小基础本体周围的水流剪应力的作用，从而大幅削弱水流的冲刷能力。一方面，水流对海床本身的冲刷作用会减弱。另一方面，水流冲刷能力减弱还可避免防冲刷覆层被快速冲刷，使防冲刷覆层保留较长时间，从而对海床起到持续的保护作用。因此，上述防冲刷的海上风机基础的防冲刷效果较好。
