System for wind power generation : Patent

■Patent name Impeller for wind power generation and wind power generation system

■Patent number 7280148

■Summary of patent content

【assignment】
We provide impellers and wind power generation systems that allow multiple wind power generation devices to be installed in a limited area to efficiently generate power from the entire area, and that can suppress the noise generated by the rotation of the impellers during wind power generation. The purpose is to

[Solution] An impeller for wind power generation comprising a plurality of blades and a hub provided with a rotating shaft at the center and arranging the plurality of blades at approximately equal intervals in the circumferential direction, the impeller for wind power generation comprising: The blades are formed to extend while increasing their width toward the outer periphery of the impeller, and the line segment connecting the leading and trailing edges of the blades is approximately 10 degrees from the plane perpendicular to the rotation axis of the impeller. As described above, the plurality of blades are inclined at an angle of about 20 degrees or less, and the plurality of blades have a portion of the trailing edge of the blade at the front in the rotational direction of the impeller and the front edge of the blade at the rear in the rotational direction. This relates to impellers for wind power generation that overlap when viewed from the front of a car.
