Flow-adjustable tail water anti-backflow device
The invention relates to the technical field of tail water backflow prevention, in particular to a flow-adjustable tail water backflow prevention device and a structural assembly, the structural assembly comprises a structural part and mounting parts, the mounting parts are arranged on the two sides of the structural part, and the backflow prevention assembly comprises a backflow prevention part arranged on one side of the structural part, an adjusting part arranged on one side of the backflow prevention part and a clamping assembly. Comprising a rotating piece arranged in a structural piece, a clamping piece and a locking piece arranged on the upper side of the structural piece in a sliding mode, a structural assembly and an anti-backflow assembly which are arranged are used in cooperation, a plug structure locked by a spring is designed at an outlet of a drainage pipe of the power station, and the other end of the spring is fixed to one side of an adjusting piece capable of being adjusted in the pipeline direction; the position of the adjusting part is changed to change the pulling force of the plug, so that the plugging force of the plug is changed, and the outlet water flow pressure adjustment, namely the outlet flow adjustment, of the power station tail water drainage pipe is realized.
本发明涉及尾水防倒灌技术领域，尤其涉及一种流量可调式尾水防倒灌装置，构造组件，包括构造件和安装件，所述安装件设置于构造件的两侧，防倒灌组件，包括设置于构造件一侧的防倒灌件和设置于防倒灌件一侧的调节件，夹紧组件，包括设置于构造件内的转动件、夹紧件和滑动设置于构造件上侧的锁止件，本发明通过设置的构造组件、防倒灌组件相互配合使用，在电站排水管出口处设计弹簧锁紧的堵头结构，弹簧的另一端固定在可沿管道方向调节的调节件一侧，改变调节件的位置，从而改变堵头拉力，进而实现堵头堵塞力的改变，实现电站尾水排水管出口水流压力调节，即出口流量调节。
