Title:
VERTICAL AXIS WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2022/153648
Kind Code:
A1
Abstract:
This vertical axis wind turbine comprises a base section (2) having a power-generating unit, a rotating section (3) that rotates in relation to the base section (2) about a vertical axis, and a plurality of wind turbine blades (10 (main blades 12)) that are linked to the rotating section (3) via arms (20) and that rotate about the vertical axis. The arms (20) each have a movable arm (23) for suppressing over-rotation, the movable arm being capable of rotating about an axis of a rotation shaft (24) connecting the rotating section (3) and a wind turbine blade (10 (main blade 12)), and the movable arms (23) are each provided with an over-rotation-suppressing guide (30 (weight 32)) that tilts the movable arm (23) about the rotation axis via the action of centrifugal force generated during the rotation of the wind turbine and returns the movable arm (23) to the initial state when the rotation of the wind turbine is stopped.
