ROTATING ASSEMBLY FOR VERTICAL-AXIS WIND TURBINE

摘要

The present invention relates to a rotating assembly for a vertical-axis wind turbine for increasing the output coefficient of the wind turbine, the rotating assembly being connected with a vertical-axis wind turbine (50) which rotates on a rotation shaft (53), thereby increasing the output coefficient of the wind turbine. The rotating assembly comprises: a plurality of air guides (10), which are radially provided on the outside of rotation blades (55) of the vertical-axis wind turbine (50), and which rotates independent of the rotation blades (55), while guiding the flow of air toward the rotation blades (55); bearings (15) which are installed on the upper and lower sides of the vertical-axis wind turbine (50) for enabling the air guides (10) to rotate freely; donut-shaped circular plates (16, 16') which are installed on the upper and lower surfaces of the air guides (10), and which rotate with the air guides (10); and a connection member (17) for connecting the bearings (15) and the circular plates (16, 16'). Accordingly, as the plurality of air guides rotate outside the vertical axis wind turbine and guide the flow of air toward the vertical-axis wind turbine, the optimum angle of attack increases when the rotation blades of the vertical-axis wind turbine rotate 360°, thereby increasing the thrust and torque and improving the output coefficient.
