Water flow hedging energy dissipation structure
The invention discloses a water flow hedging energy dissipation structure which is mainly composed of a well body, a water inlet pipe, a water outlet pipe and a roundabout flow groove with a turn-back curve in the well body. Water flow entering the well body is divided into two parts, the two water flows are opposite when flowing to the other end of the well body, the two water flows are equal in flow and opposite in direction, and kinetic energy of the water flows is offset through opposite flushing. And the water flow is divided into two parts after being turned, and is continuously and repeatedly divided, headed, divided and headed, so that the energy of the water flow is consumed, and an energy dissipation effect is achieved. The defects that in the prior art, water flow of a drop structure flows in the same direction, energy is continuously superposed, and drop height is limited are overcome. The launder is arranged in a split-flow collecting and opposite-flushing alternating mode, energy of water flow is reduced under the action of the water flow, and energy superposition and accumulation are avoided. The device is suitable for large-fall projects such as drainage pipelines and water conservancy projects.
本发明公开一种水流对冲消能构筑物，主要由井体、进水管、出水管和井体内迂回的曲线折返的流槽组成。进入井体内水流分为两部分，流至井体另一端时两股水流对冲，两股水流的流量大小相等方向相反，对冲相互抵消了水流的动能。水流转向后再分成两部分，不断反复分流—对冲—分流—对冲，消耗水流的能量，起到消能作用。克服了现有技术跌水构筑物水流朝向同一方向流动，能量不断叠加，跌水落差受限的缺陷。流槽采用分流汇集对冲交替的布置方式，利用水流自身作用消减水流的能量，没有能量叠加积累。适应于排水管道、水利工程大落差等工程中应用。
