Abstract

The utility model discloses a water turbine runner, including upper ring, lower ring and blade, its characterized in that, the blade is several, and is welded between upper ring and lower ring, the blade's front end has the blade swing head of rotatable, can change the flow and angle adjustment of water turbine inlet, makes the efficiency and operation reliability of water turbine improve. The rotatable blade swing head set up at the blade front end can dynamically adjust the flow and angle of inlet according to real-time water flow condition. Through the rotation of swing head, can accurately match the water flow characteristics under different water level, flow rate, make water turbine still keep high -efficient energy conversion under the non -design condition, avoided the problem of the efficiency of traditional fixed blade because of water flow fluctuation and sudden drop.
