摘要： A locking device for locking a turbine blade of a wind power plant at a predetermined pitch angle, which wind power plant includes a rotor hub and at least one turbine blade where the blade root of the at least one turbine blade is connected to the rotor hub through a pitch bearing so that the pitch angle of the at least one turbine blade is adjustable by turning of the at least one turbine blade about its longitudinal axis relative to the rotor hub and wherein the device for locking the turbine blade includes a mechanical snap-in mechanism which in a locked position prevents the at least one turbine blade from turning about its longitudinal axis thus fixating the at least one turbine blade in the predetermined pitch angle.
