Continuous diffusion type flip flow energy dissipation structure
The invention relates to a continuous diffusion type flip bucket energy dissipation structure which comprises a discharge chute, a side wall and a continuous diffusion type flip bucket, the discharge chute is provided with a slope section and a reverse arc section, the slope section and the reverse arc section are sequentially arranged in the first direction, the slope section is tangent to the reverse arc section, and the first direction is the extending direction of the discharge chute from the upstream to the downstream; the side walls are located on the two sides of the discharge chute and arranged in the first direction, and the side walls have preset heights; the continuous diffusion type flip bucket is provided with a reverse cambered surface, the flip angles of the reverse cambered surface are symmetrically distributed along the center line in the width direction of the discharge chute and are uniformly changed, the minimum flip angle of the reverse cambered surface is defined as theta1, the maximum flip angle of the reverse cambered surface is defined as theta2, theta1 is larger than or equal to 0 degree and smaller than or equal to 10 degrees, and theta2 is larger than or equal to 25 degrees and smaller than or equal to 35 degrees; the continuous diffusion type flip bucket comprises a center flip bucket and side flip buckets, the center flip bucket is located in the middle, and the side flip buckets are located on the two sides close to the side wall. The continuous diffusion type flip flow energy dissipation structure can reduce the impact of water flow on the bottom of a riverbed.
本申请涉及一种连续扩散式挑流消能结构，包括泄槽、边墙和连续扩散式挑流鼻坎，泄槽具有斜坡段和反弧段，斜坡段和反弧段沿第一方向依次布置，斜坡段与反弧段相切，第一方向为泄槽的上游到下游的延伸方向；边墙位于泄槽的两侧并沿第一方向布置，边墙具有预设高度；连续扩散式挑流鼻坎具有反弧面，反弧面的挑射角度沿泄槽宽度方向的中心线对称分布且挑射角度均匀变化，定义反弧面的最小挑射角为θ1，反弧面的最大挑射角为θ2，则：0°≤θ1≤10°，25°≤θ2≤35°；连续扩散式挑流鼻坎包括中心挑坎和边侧挑坎，中心挑坎位于中间位置，边侧挑坎位于靠近边墙的两侧；该连续扩散式挑流消能结构能够降低水流对河床底部的冲击。
