Offshore wind power single-pile foundation scouring protection device
The invention discloses an offshore wind power single-pile foundation scouring protection device. The offshore wind power single-pile foundation scouring protection device is characterized in that a turbulent flow bottom plate and lateral turbulent flow plates are fixed on a single-pile foundation; one end of the single-pile foundation is fixed in a seabed, the single-pile foundation is firmly connected with the seabed and is not easily scoured away by ocean current, and the turbulent flow bottom plate is fixed on the outer side of the single-pile foundation to form a seabed protection layer structure; multiple annular turbulent flow plates are fixed to the upper end of the turbulent flow bottom plate, and the annular turbulent flow plates can effectively reduce the water flow velocity at the seabed surface and reduce the seabed scouring effect; meanwhile, the pressure of seawater on the turbulent flow bottom plate can be utilized, and the scouring phenomenon between the single-pile foundation and the seabed is effectively prevented; the lower end of the turbulent flow bottom plate makes contact with the surface of the seabed; meanwhile, the bottom of the turbulent flow bottom plate can fix the bottom of the seabed; the plurality of lateral turbulent flow plates are evenly arrayed in the circumferential direction of the single-pile foundation, the purpose of weakening vortex formation around a pile body through the lateral turbulent flow plates is achieved, and then the seabed scouring effect is weakened; and the structure is simple, the flow speed of seawater around the pile is effectively reduced, and generation of large vortexes around the pile is reduced.
本发明公开了一种海上风电单桩基础冲刷防护装置，通过在单桩基础上固定扰流底板和侧向扰流板，将单桩基础一端固定于海床内，同单桩基础连接牢固，不易被洋流冲刷走，将扰流底板固定于单桩基础外侧，形成海床护层结构，在扰流底板上端固定有多个环形扰流板，利用环形扰流板能够有效降低海床面处水流流速，降低海床冲刷效应的作用，同时能够利用海水对扰流底板的压力，有效防止单桩基础与海床之间冲刷现象，扰流底板的下端与海床表面接触，同时扰流底板的底部能够固定海床底部，单桩基础周向均匀阵列有多个侧向扰流板，利用侧向扰流板减弱桩身周围旋涡形成的目的，进而减弱海床冲刷效应，本发明结构简单，有效降低桩周海水流速、减少桩周大涡生成。
