<p>The invention relates to a wind turbine with a vertical rotation axis for multiple uses, meant for wind kinetic energy conversion into conventional energy (electric or mechanical) and for advertisement display. According to the invention, the turbine consists of a central axle, whereon there are fixed, at 120°, three systems () for clamping some rectangular blades (), fixed through some rocker arms (), which rotate through a system of two parallel bearings (), under an angle delimited by two levers, a lever () keeping the blade () in a closed position and another lever () with a counterweight which keeps the blade () open; and the three systems () of blades () are closed by a third of a complete turbine rotation and are opened by two thirds of the complete turbine rotation of 360° in order to eliminate the braking, and for facilitating the opening and closing of the blades (), the rotation angle of the rocker arm () within the bearings () is limited to 88° by the two levers () through some stop-bars () with elastic buffers.</p> |
