Collapsible vertical-axis wind turbine

A collapsible wind turbine, comprising:

• a. a turbine with a vertical axis (A) and cross flow, the turbine comprising blades moved by the wind;
• b. an electric generator, the shaft of which is rotatable about a generator axis (G), driven in rotation by the turbine;
• c. a holding structure for the turbine, which comprises at least one vertical pylon, with a longitudinal axis (L), and a pivot hinge, said pylon being connected to the ground by said hinge and being mounted pivotably about said hinge according to a folding axis (R) (typically horizontal) between a substantially vertical working position and a collapsed position (for example substantially horizontal;
• d. top and bottom linking members, which rigidly hold the turbine by its axis of rotation (A) and maintains a separation between it and the pylon, the axis of rotation (A) of the turbine being parallel to the longitudinal axis (L) of the pylon;
• and
• e. at least one flexible transmission link connecting and synchronizing the rotation of the rotation shaft of the generator and the rotation shaft of the turbine by linear travel of said at least one flexible link in a closed-circuit path, such that the movement of the turbine drives the generator by its rotation shaft.
