Abstract
The utility model discloses a rotating impeller of a hydraulic turbine, which comprises a wheel disc body, wherein the center position of a rotating disc body is provided with a shaft hole for assembling a center rotating shaft of the hydraulic turbine, the outer edge of the rotating disc body is uniformly provided with a plurality of spoon-shaped impellers, the back surfaces of the spoon-shaped impellers are in a sliding-surface semicircle structure, and the sliding-surface semicircle structure of the impellers is provided with bearing blocks which are used to increase the strength of the impellers. The rotating impeller of the hydraulic turbine uses the impellers in a spoon-shaped structure, thereby effectively leading the rotating impeller to reduce the driving flow rotating torque in waste water of the inner portion of the hydraulic turbine, and increasing the rotating power of the hydraulic turbine. Simultaneously, the back surfaces of the spoon-shaped impellers are a sliding surface semicircle structure, thereby effectively leading the rotating impeller to reduce the resistance in accumulated water of the inner portion of the hydraulic turbine, the impellers are further provided with the bearing blocks which are used to increase the strength of the impellers, thereby leading the impellers not to easily deform in high speed water flow. The structure thereof is simple, the conception is ingenious,, the water feeding resistance of the hydraulic turbine is effectively reduced, and the rotating impeller of the hydraulic turbine is suitable to universally extend and use.
