Document Type and Number:
WIPO Patent Application WO/2021/033419
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vane wheel and a wind power generation system, in which a plurality of wind power generation apparatuses are installed in a limited area, and that can efficiently generate electricity through the entire area and restrain noise caused by rotation of the vane wheel during wind power generation to be reduced. The present invention relates to a vane wheel for wind power generation comprising: a plurality of vanes; and a hub in which a rotation shaft is provided at the center thereof and the plurality of vanes are arranged at substantially-equal intervals in a circumferential direction. The vanes are formed so as to extend while widening toward the outer circumference of the vane wheel. A line segment connecting a leading edge and a trailing edge of the vane is inclined such that the angle between the line segment and a plane perpendicular to the rotation shaft of the wind vane should be approximately 10º or more and approximately 20º or less. In the plurality of vanes, the trailing edge of the vane provided forward in a rotation direction of the vane wheel and the leading edge of the vane provided backward in the rotation direction partially overlap in a front view of the vane wheel.
