Water diversion method for raising water head of small river hydropower station
The invention provides a water diversion method for raising a water head of a small river hydropower station. The water diversion method comprises the step of arranging a water diversion tunnel, a surge shaft, a Y-shaped branch pipe and a stepped pressure vertical shaft. The diversion tunnel takes a water inlet of the hydropower station as a starting point and a surge shaft as an end point. A Y-shaped branch pipe is connected behind the surge shaft, and one pipe of the diversion tunnel is changed into two pipes. And the Y-shaped branch pipe is connected with two step pressure vertical shafts which are arranged in parallel. The two step pressure vertical shafts are composed of four sections of adit and three sections of vertical shafts which are arranged in parallel, and the end point is a water inlet ball valve of the unit plant. By means of the water diversion method, the water head of the hydropower station can be obviously lifted to 845-922 m, the introduced flow is increased by two times, the loss of the water head is reduced, the generating capacity can be obviously improved, and the scale of a large hydropower station is achieved.
本发明提供了一种小型河流水电站抬高水头的引水方法，包括设置引水隧洞、调压井、Y型岔管和梯级压力竖井。引水隧洞以水电站进水口为起点，终点为调压井。调压井后接Y型岔管，将引水隧洞一管变两管。Y型岔管后接平行布置的两条梯级压力竖井。两条梯级压力竖井由平行布置的四段平洞和三节竖井组成，终点为机组厂房的进水球阀。通过该引水方法可将水电站水头显著抬高至845‑922m，并将引用流量增加2倍，不仅减少水头损失，还可显著提升发电量，达到大型水电站规模。
