Title:
A BLADE SUPPORT LIMB STRUCTURE OF VERTICAL AXIS WIND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2008/046283
Kind Code:
A1
Abstract:
A blade support limb structure of vertical axis wind power generator includes a
fixed support limb (1) and a rotatable support limb (2), one end (21) of the rotatable support
limb is connected with one end (22) of the fixed support limb and the rotatable support
limb may rotate around it. The structure keeps a wind wheel at stable rotation speed
in the case of environmental wind speed exceeds rated wind speed, thereby to ensure
that vertical axis wind power generator outputs constant power. The structure
solves a problem of constant power output of vertical axis wind power generator
from hundreds watt to thousands watt, so its applications are wide.
