Differential adverse slope type energy dissipation aeration structure
The invention relates to a differential adverse slope type energy dissipation aeration structure. A differential flip bucket is connected with a step horizontal plane at the tail end of a stepped overflow dam face, an adverse slope type stilling pool is located behind a linear transition section, the differential flip bucket is connected with the adverse slope type stilling pool through the lineartransition section, and a trapezoidal protruding circular energy dissipater is arranged in the adverse slope type stilling pool. By combining the differential flip bucket with the adverse slope typestilling pool and combining two energy dissipation modes of flip bucket energy dissipation and underflow energy dissipation, the differential flip bucket greatly diffuses water flow in the vertical direction, and scouring of the water flow to a riverbed can be effectively weakened. The trapezoidal convex circular energy dissipater arranged on the adverse slope type stilling pool can reduce the height of a ''water wing'' and optimize the flow state of the water flow, the protruding circular weakens cavitation damage to a certain extent, and the service life of the energy dissipater is prolonged.
本发明涉及一种差动反坡式消能掺气结构。本发明差动式挑坎与阶梯溢流坝面末端台阶水平面相连，反坡式消力池位于直线过渡段之后，差动式挑坎与反坡式消力池通过直线过渡段连接，反坡式消力池布置梯形凸起圆形消能工。本发明通过将差动式挑坎与反坡式消力池相结合，将挑流消能与底流消能两种消能方式相结合，差动式挑坎在垂直方向对水流有较大的扩散，能够有效减弱水流对河床的冲刷。反坡式消力池上设置的梯形凸起圆形消能工能够降低“水翅”高度，优化水流流态，凸起圆形设置在一定程度上减弱空化空蚀危害，延长消能工使用寿命。
