WIND POWER GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a wind power generator capable of generating power of a high output by efficiently increasing the speed of a wind flow in the wind power generator provided with a wind mill to be rotated within a wind tunnel body. SOLUTION: This wind power generator is provided with the cylindrical wind tunnel body 1 to be expanded in a wind flow direction and the wind mill 3 for power generation arranged in the vicinity of an inflow port 2a for wind of the wind tunnel body 1. An inclined angleϕof a side tunnel part for a shaft of the wind tunnel body 1 is set to a range of 5 to 25°. The inflow port 2a of the wind tunnel body 1 is made as a curved surface 5 smoothly expanded toward the outside of the wind tunnel body 1. A collar-shaped piece 4 of a width B is provided at the outside of an opening edge of the inflow port 2. Wind made to flow from the inflow port 2a for wind of the wind tunnel body 1 becomes fast by being rapidly accelerated in the vicinity of the inflow port 2a to efficiently rotate the wind mill 3 arranged in this part and to generate power of the high output by rotation of the wind mill 3.
