<P>PROBLEM TO BE SOLVED: To provide a large wind power generator that uses an air channel with a flange ring, which is considered to be difficult to apply in large windmills provided, in a horizontal axis type wind power generator. <P>SOLUTION: The horizontal axis type windmill 10 is surrounded by the air channel 20 equipped with the flange ring 23. The flange ring 23 in the air channel 20 protrudes in an annular shape in a radial direction in the periphery of a rear opening 20B of an air channel body 21, and consequently, when the bore of the air channel 20 is large, enormous resistance is generated, particularly when there are strong winds. The flange ring 23 is therefore formed as an assembly of many sector flanges 22 in a block construction. Each sector flange 22 is configured so as to be supported freely tiltable via a flange drive member 31 such as an air cylinder or the like controlled at a constant pressure, and each sector flange 22 takes a leaned attitudes to prevent the increase of resistance in a strong wind exceeding a prescribed safe wind speed range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
