PROBLEM TO BE SOLVED: To ressolve such a problem that, in wind power generation, density of air is low, a windmill is increased in size, and when a wind power is below the limit of generating efficiency, a generator is not operated and control of the number of revolutions is impracticable during a storm and a typhoon. SOLUTION: A wind tunnel is manufactured by right and left air pressure regulating panels arranged on which respective hydraulic cylinders are mounted. By increasing a wind pressure applied on a blade, two impellers are rotated and their rotation forces are caused to be confluent to each other at a single gear by a belt and a pulley to constitute such that a generator is driven. By controlling a hydraulic cylinder, the two wind pressure regulating panels are automatically opened and closed and control of the number of revolutions is practicable during a storm and a typhoon. |
