<p>PROBLEM TO BE SOLVED: To provide a double wind-turbine type wind power generator capable of performing a simultaneous adjustment of blade angles at the front and rear wind turbines.SOLUTION: This invention relates to a double wind-turbine type power generator in which two main shafts 4 are mounted at the upper end of a tower under horizontal or angular attitude and one outside end of each of the main shafts is provided with blades. The main shafts are constituted to have a hollow shape. Around the main shafts, the first rod 10A is connected to a clutch 12 to change a motion into a forwarding or retracting motion by a motor 7A, ball screws and a linear guide or by the motor and hydraulic equipment out of the main shaft case while being separated from the main shafts, the second rod 11 in the main shaft is arranged to extend in an axial direction, one end part of the second rod is connected through an insertion and passing hole for the main shafts to a clutch plate, a cylinder 14A is fixed to the base part of the blade at the extremity end of the main shaft, there is provided a container storing a bearing and a shaft part of the blade so as to flow in or flow out oil or a rotary actuator, they are connected to a cylinder with a pipe and the shaft part of the blade is normally rotated or reversely rotated to enable a blade angle to be adjusted. In addition, the two main shafts are slanted at a certain angle through a constant velocity joint.</p> |
