Vertical axis wind turbine with actuator driven by centrifugal force

摘要

PURPOSE: A vertical-axis wind turbine with an actuator driven by a centrifugal force is provided to obtain insufficient lift in case of low wind speed or in initial driving by employing a lift support blade. CONSTITUTION: A vertical-axis wind turbine comprises a draft support blade(200) which is installed on the underside of an arm(20) and rotated by the centrifugal force of a main blade and the arm to contact the bottom surface of the arm, a lift support blade(100) which is formed in a lift type air foil shape and rotated on the upper side of the arm, and an actuator(300) which has a gear for linking the draft and lift support blades, a lift side gear(310) which is formed on one end of a rotary shaft(110), and a draft side gear(320) which is rotated by engaging with the lift side gear on one end of a rotary shaft(210).
