A wind power installation is described having a flow channel (1) between two channel walls (2), at least one of which forms an outer wall of a structure (3), having at least one wind turbine (6) which is mounted within the flow channel (1) and the rotor axis of which runs vertically, and having a guide device (11) which shields the turbine rotor (7) in the area of the circumferential side thereof which rotates against the incident-flow direction. In order to ensure advantageous flow conditions, it is proposed that the channel wall (2) form the guide device (11) in the inflow area of the flow channel (1) on the circumferential side of the turbine rotor (7) which rotates against the incident-flow direction, and surrounds the turbine rotor (7) in a circumferential area (12) on the incident-flow side, and that that channel wall (2) which forms the guide device (11) be fitted with a guide wall (13) on the output-flow side of the wind turbine (6), which guide wall (13) is borne on the end face thereof which is remote from the wind turbine (6) such that it can pivot about an axis (14) which is parallel to the rotor axis. |
