Abstract
A wind turbine () comprising a tower (), a nacelle () and a hub () is disclosed. The hub () comprises a blade canying structure () with one or more wind turbine blades () connected thereto. Each of the wind turbine blades () is connected to the blade canying structure () via a hinge () at a hinge position of the wind turbine blade (), each wind turbine blade () thereby being arranged to perform pivot movements relative to the blade carrying structure () between a minimum pivot angle and a maximum pivot angle. The wind turbine () further comprises a stop mechanism arranged to move the wind turbine blades () to a safe pivot angle in the case of an emergency, the stop mechanism comprising a release mechanism () and at least one wire () interconnecting the release mechanism () and each of the wind turbine blades (). Activation of the release mechanism () causes an abrupt change in a pulling force applied to the wind turbine blades () by the wire(s) (), the change in pulling force causes the wind turbine blades () to move immediately to the safe pivot angle.
