Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotary vane type Darrieus type wind power generator capable of speedily coping with change of wind directions and wind speed, having resistance to strong wind of a typhoon or the like, reducing noise and vibration, being eco-friendly to human and animals, achieving strong wind power collecting capability, and achieving profitability, which can be installed in an urban area. <P>SOLUTION: Wind is efficiently fed to a Darrieus type windmill at the optimum angle by rotary vanes with a vertical tail. A vibrator installed on a vertical shaft of the Darrieus type windmill rotates the Darrieus type windmill through gears. When strong wind of a typhoon or the like occurs, rotation of the windmill can be stopped by means of a shutter at a front part of the rotary vane. <P>COPYRIGHT: (C)2004,JPO

The present invention relates to a profitable rotor-type Darrieus-type wind power generator that has little vibration and can be used anywhere.

なる。2. Description of the Related Art A propeller-type wind power generator is a viscous fluid device in which a turbine, a gearbox, and a generator are combined, and has a simple structure. However, in order to extract energy from wind with a viscosity that is as low as 800 times lower than that of water, a large turbine with a diameter about 30 times that of hydroelectric power generation is required.

い国土に人口密度の高い日本の実情に合わない。The harmful effect of the propeller type wind power generator is mainly caused by the high speed rotation of the turbine. The air has a low viscosity and the maximum efficiency point is high when the number of blades is as small as three. If there is a concern about noise, it is an environmental condition that the residential area is about 300 m away. There are problems of wildlife protection and anxiety caused by dangerous images. A propeller-type wind power generator with a knife rotating at high speed cannot be placed in the Japanese environment. Since the wind in Japan is in a region relatively close to mountains, forests and buildings, the wind conditions around it contain a lot of turbulent components. Under such conditions, there are many typhoons and it is not suitable for Japan, which has a high population density in a small land area.

い。The vertical axis type wind power generator has a low center of gravity because the generator is placed under the vertical axis type wind turbine, and the propeller does not generate wind noise. It can also handle wind conditions that contain a lot of turbulence components that occur because mountains, forests, buildings, etc. are relatively close. However, high speed rotation is not possible if only drag is used.
