Title:
FIXED DIRECTION ROTATION WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2010/029605
Kind Code:
A1
Abstract:
A fixed direction rotation wind turbine which can take out wind power efficiently as a rotating force through a simple mechanism. A wind power blade (10) having a cross-sectional profile of “open four vertical angle polygon” intersecting the axial direction perpendicularly is arranged radially from n equal portions of circumference and point symmetrically about a rotating shaft (1) through a shaft (2). The “open four vertical angle polygon” is configured such that the one end forms a convex surface and the other end forms a convex surface. The virtual extension of the convex surface (S5) is arranged to touch the concave surface (S1). Furthermore, a U-shaped band (11) is arranged on the inner circumferential surface of the wind power blade (10) such that the shaft (2) is positioned on the concave surface side.
