Title:
CYLINDRICAL WINDMILL FOR WIND TURBINE GENERATOR, HAVING VARIABLE WING ANGLES ACCORDING TO WIND DIRECTION
Document Type and Number:
WIPO Patent Application WO/2016/002991
Kind Code:
A1
Abstract:
The present invention, relates to a cylindrical windmill for a wind turbine generator in which vertical wing plates, supported on circular ends plates respectively attached at both ends of a rotating shaft, are rotated by a driving power. The present invention is a cylindrical windmill for a wind turbine generator, which has variable wing angles according to the wind direction, and comprises: fixing bars (30) spaced and fixed radially at certain angles to circular end plates (10) and linking vertical wing plates (20) and angle adjusting hinge shafts (32) on the ends thereof; an eccentric coupling (40) linked from the top end of a rotating shaft (31) coupled to the circular end plates (10) to a first bearing (41) and having an eccentric projection (43) projecting from the top surface thereof; a donut-shaped eccentric circular plate (50) linked by a second bearing (42) to the outer surface of the eccentric projection (43); a wind direction bar (60) integrally fixed to the top surface of the eccentric projection (43); and a link portion (70) connecting the eccentric circular plate (50) and each vertical wing plate (20) so as to adjust the distances therebetween, and enabling the wind direction angles of the vertical wing plates (20) to be varied with respect to the hinge shafts (32).
