Abstract
A collapsible wind turbine includes a turbine with a vertical axis (A). The turbine is supported by a vertical pylon, pivotably mounted about a hinge, and by linking members connecting the rotation shaft of the turbine to the pylon while maintaining a separation therebetween. The wind turbine includes: —an electricity generator of which the axis of rotation is perpendicular to the longitudinal axis of the pylon, the generator being secured to the ground; and—at least one flexible link connecting and synchronising the rotation of the generator with the rotation shaft of the turbine by linear travel of the flexible link in a closed-circuit path, so as to drive the rotation shaft of the generator by the movement of the turbine. The present structure is, in particular related to land-based wind turbines in a cyclone-prone area.
