    An electromechanical operation mechanism of propeller for water turbine can be used to adjust the aperture of propeller for water turbine in stead of hydro-cylinder system. The output shaft of servomotor and reduction gear will be connected with the trapezoidal screw in main shaft of machine set as the up section of trapezoidal nut sheath to be connected to the screw thread of trapezoidal screw and the down end to operation shaft which directly connects with the operation mechanism of propeller in rotary wheel body of water turbine. The servomotor and reduction gear will be fixed at up end of main shaft for machine set through supporting frame and be connected to the main shaft by bilateral thrust bearing. It is better to use DC servomotor and harmonic reduction gear and there will a feedback device near trapezoidal nut sheath to reflect the rotary angle changes of propeller.
