<P>PROBLEM TO BE SOLVED: To provide a propeller type turbine device for wind power generation enabling reliable use even with respect to strong wind while having a simple and inexpensive configuration. <P>SOLUTION: Main blades 3 are rotatably supported around main blade shafts 4, and auxiliary blades 7 are fixed and connected to base end parts of the main blades 3 via angle members 6. When receiving wind W from the front side, the auxiliary blade 7 is pressed rearwardly, and then, a moment corresponding to the intensity of the wind W is generated around the main blade shaft 4 by the auxiliary blade 7. Thus, a pitch angle of the main blade 3 is automatically adjusted, and an angle of the main blade 3 with respect to the direction of the wind W is reduced, so as to prevent increase in rotational frequency of the main blade 3 around an output shaft 1 to a predetermined value or more. <P>COPYRIGHT: (C)2010,JPO&INPIT |
