<P>PROBLEM TO BE SOLVED: To improve a shape of a blade, a rotary shaft, conversion efficiency of wind speed (wind power) to rotation force, safety to 2 to 3 times of a conventional model irrespective of blade type, a propeller type or a vertical blade type to spread practical small wind power generator. <P>SOLUTION: The blade is a fan shape and has area of a fourth of a circle. A ring shape speed increasing device of this application same invention is used for low speed rotation and a generator shaft is rotated at high speed. A cone and small diameter shaft are used for a rotation shaft in parallel. A direction of a blade can be changed at a time of strong wind to cope with breeze and strong wind. A system reverse to a conventional one is adopted for whole structure, efficiency is increased to twice or more of the conventional model to enable to manufacture the practical small size wind power generation device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
