Title:
WIND-DRIVEN POWER GENERATOR AND CONSTRUCTION METHOD FOR THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/105260
Kind Code:
A1
Abstract:
A lifting device (3) is placed at the upper end of a tower (1) so as to be horizontally
rotatable, and the lifting device (3) lifts and lowers a wind-driven power generation
unit (4). This increases safety of the wind-driven power generation unit (4)
in strong wind and facilitates maintenance. Also, a rotating member (6) having
a fish shape cross-section and rotating horizontally by wind is attached to the
tower (1), and this reduces overturning moment on the tower (1).
