Steep slope energy dissipation facility
The invention discloses a steep slope energy dissipation facility. The facility comprises an inlet connecting section, a control gate section, a steep slope energy dissipation section and an outlet connecting section which are sequentially arranged in the water flow direction, wherein the steep slope energy dissipation section comprises a steep slope, a plurality of stilling pools arranged in the inclination direction of the steep slope and auxiliary stilling devices arranged between the adjacent stilling pools, and the auxiliary stilling devices are used for separating water flow; and a back-flushing device is arranged on the rear wall of the stilling pool at the bottommost end of the steep slope and generates back-flushing water flow opposite to the flow direction of the discharged water flow at a certain angle. According to the facility, the back-flushing device is used for generating back-flushing water flow, counter-impact force is provided for discharged water flow, and the discharged water flow and the back-flushing water flow are mixed, so that the hydraulic jump condition of the water flow is controlled, and the purpose of improving the energy dissipation rate is achieved.
本申请涉及一种陡坡消能设施，其包括沿水流方向依次设置的进口连接段、控制闸段、陡坡消能段以及出口连接段；所述陡坡消能段包括陡坡、沿陡坡的倾斜方向设置的若干消力池、设置在相邻所述消力池之间的辅助消力装置，所述辅助消力装置用于分隔水流；位于所述陡坡最底端的消力池的后壁设置有反冲装置，所述反冲装置以一定角度产生与下泄水流流向相反的反冲水流。本申请利用反冲装置产生反冲水流，给下泄水流以反击力，使下泄水流和反冲水流掺杂，从而控制水流的水跃状况，达到提高消能率的目的。
