Anticorrosion efficient water turbine

The utility model provides an anticorrosion efficient water turbine mainly used for hydroelectric power plants. One end of a water turbine water inlet pipe is arranged as a V-shaped throat and connected with an accelerating pipe, an air pipe is mounted at a 120-degree angle with the water flow direction in the accelerating pipe, a speed sensor is arranged on the inner wall of the accelerating tube and connected with an air generator via a PLC (programmable logic controller), the accelerating pipe is mounted at a 60-degree angle with the water turbine, multiple blades are arranged inside the water turbine, and a water discharge pipe is arranged on one side of the lower portion of the water turbine. According to the principle of air jet flow, work utilization rate of hydroenergy is increased, energy is saved, generated power can be improved, cavitation can be reduced by aerified high-speed water flow, and service life of the water turbine is prolonged.
