Arc-shaped anti-scouring device for tidal current energy water turbine foundation
The invention discloses a tidal current energy water turbine foundation arc-shaped anti-scour device which comprises an arc-shaped plate structure erected outside a water turbine foundation, the arc-shaped plate structure is used for guiding bottom-layer water flow to smoothly pass through the water turbine foundation, and the arc-shaped plate structure comprises two symmetrical arc-shaped parts. The midpoint of a straight line connected by connecting points of the two arc-shaped parts coincides with the circle center of the water turbine foundation; and the lower half part of the arc-shaped plate structure is buried in the seabed. According to the arc-shaped anti-scour device for the tidal current energy water turbine foundation, the arc-shaped plate structure is adopted, and the lower half part of the arc-shaped plate structure is buried in the seabed, so that the overflowing capacity near a water turbine is not affected, bottom-layer water flow can be fully guided to smoothly pass through the water turbine foundation, and wake vortex structures are reduced; the direct impact of water flow on a water turbine foundation and the scouring effect of subsurface flow on a seabed are weakened, and an upstream and downstream axial symmetry structure is formed by arranging two symmetrical arc-shaped parts so as to be suitable for engineering structures such as tidal current energy water turbines in a complex reciprocating flow environment.
本发明公开了一种潮流能水轮机基础弧形防冲刷装置，包括架设于水轮机基础外部的弧形板结构，其中，所述弧形板结构用于引导底层水流平顺绕经水轮机基础，包括两个相对称的弧形部，且两个弧形部的连接点所连直线的中点与水轮机基础的圆心相重合；所述弧形板结构的下半部分埋设于海床内。该潮流能水轮机基础弧形防冲刷装置，通过采用弧形板结构并将其下半部分埋设于海床内，既不影响水轮机附近的过流能力，又能充分引导底层水流平顺绕经水轮机基础，减少尾流涡结构，削弱水流对水轮机基础的直接冲击和下潜流对海床的冲刷作用，通过设置两个相对称的弧形部，形成上下游的轴对称结构，以适用于潮流能水轮机这类处于复杂的往复流环境中的工程结构。
