Abstract

PROBLEM TO BE SOLVED: To effectively recover wind power energy by arranging a plurality of trumpet-like air guide cylinders extended forward on the same axis serially so that the front end part is overlapped with the rear end part of the former cylinder, and arranging a propeller for driving a generator on the inside of the rear end part of the last wind guide cylinder. SOLUTION: A base 2 is rotatable around a support shaft 1, and rotated so that the front surface of each wind guide cylinder 4 is regularly turned to windward, the air flow carried into the front part of the front wind guide cylinder 4-1 is increased in speed, and discharged from the rear end thereof in the pressurized state. It is then carried into the following wind guide cylinder 4-2, and the air flow blowing from the front is also effectively sucked through the clearance between the rear part of front wind guide cylinder 41 and the front part of the following wind guide cylinder 4-2 to increase the air quantity within the following wind guide cylinder 4-2. The air flow is gradually increased in speed to a high speed according to the number of the wind guide cylinders 4, and a propeller 6 is rotated at high speed by the air flow discharged from the last wind guide cylinder 4-4 to effectively generate a power by an arranged generator 8.
