Abstract (en)
[origin: WO2019219702A1] The present invention relates to a collapsible wind turbine (10) comprising a turbine (30) with a vertical axis (A). The turbine is supported by a vertical pylon (20), pivotably mounted about a hinge (22), and by linking members (43, 41) connecting the rotation shaft of the turbine to the pylon while maintaining a separation therebetween. The wind turbine comprises: - an electricity generator (70) 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 (60) connecting and synchronising the rotation of the generator with the rotation shaft of the turbine by linear travel of said flexible link in a closed-circuit path, so as to drive the rotation shaft of the generator by the movement of the turbine. The field of the invention is, in particular, that of land-based wind turbines in a cyclone-prone area.
