<P>PROBLEM TO BE SOLVED: To improve an instable structure in a wind power generating device and to enhance availability factor of equipment. <P>SOLUTION: This wind power generating device is provided with a step-up gear 2 and a generator 3 disposed in a foundation part 1, and a windmill 10 pivotally supported by an installed frame body 4 assembled to a lattice-like shape above the foundation part 1. The rotation shaft 11 of the windmill 10 is connected to the generator 3 through the step-up gear 2. The windmill 10 is provided with: the rotation shaft 10; two discs 12, 13 mounted so as to extend in their radius directions with their centers conformed to the rotation shaft 10; a plurality of blade members 15 (for example, 9 blades) disposed on the circumferences of the discs 12, 13 at equal intervals; and an elastic supporting mechanism 17 to elastically support the blade member 15 so that the pressure receiving surface of the blade member 15 is disposed along the tangential direction of the circumference (the normal line of the pressure receiving surface faces the shaft center of the rotation shaft 11). Since the step-up gear 2 and the generator 3 are installed in the foundation part 1, this wind power generating device has a stable structure, and the availability factor of equipment is enhanced. <P>COPYRIGHT: (C)2003,JPO |
