Rotary energy dissipation scouring protection method and rotary impeller energy dissipation device
According to the rotary energy dissipation scouring protection method and the rotary impeller energy dissipation device, the rotary impeller energy dissipation device needs to be arranged near a to-be-protected structure, and when the to-be-protected structure is subjected to one-way flow or two-way flow but the flow speed of one side is high, the rotary impeller energy dissipation device can be arranged at the upstream position of the strong flow direction of the to-be-protected structure; the connecting line of the rotating impeller energy dissipation device and the to-be-protected structure is basically parallel to the flow direction so as to ensure that a low-speed wake flow area generated by rotating energy dissipation acts on the to-be-protected structure; when a to-be-protected structure is subjected to the action of reciprocating flow direction strong flow with similar strength, rotating impeller energy dissipation devices can be arranged on the two sides of the to-be-protected structure correspondingly, so that the to-be-protected structure can be subjected to the action of a low-speed wake flow area in any flow direction, and the scouring protection effect is achieved. The flow velocity of incoming flow acting on the foundation structure is directly reduced, the scouring influence of high-speed water flow on the foundation structure is fundamentally reduced, the purpose of scouring protection is achieved, power generation application can be considered, and the method is a novel green scouring protection mode and has huge application potential in the scenes of cross-sea long bridges, offshore wind power and the like.
本发明提供了一种旋转消能冲刷防护方法及旋转叶轮消能装置，需要将旋转叶轮消能装置设于待防护结构附近，当待防护结构所受为单向流或为双向流但有一侧流速较强时，可将旋转叶轮消能装置布设于待防护结构物强流向的上游处，旋转叶轮消能装置与待防护结构的连线应与流向基本平行，以确保旋转消能产生的低速尾流区域作用在待防护结构物上；当待防护结构受强度相近的往复流向强流作用时，可在待防护结构两侧分别布置旋转叶轮消能装置，使待防护结构在任一流向时均能受到低速尾流区域作用并获得冲刷防护效果，本发明通过上游装置旋转消能产生的低速尾流区，直接降低作用于基础结构的来流流速，从根本上降低高速水流对基础结构的冲刷影响，达到冲刷防护的目的，且可兼顾发电应用，是一种新颖的绿色冲刷防护方式，在跨海长桥、海上风电等场景具备巨大的应用潜力。
