Abstract

A wind power installation with a rotor which has two or more rotor blades and which is rotatably bearing-supported for rotation around a rotor rotation axis. The rotor is connected to a generator for generating electrical power. The rotor and the generator form a part of a turbine which is received by a turbine carrier. The turbine carrier is rotatably arranged at a supporting structure. The turbine is movably mounted in the turbine carrier via a bearing device so that the spatial position of the turbine in the turbine carrier can be modified. A pivoting range of the turbine corresponding to a pivoting range of the rotor rotation axis includes a first angle range and a second angle range relative to a reference plane, and the entire pivoting range is at least 120°.

Dependent claims

A wind power installation comprising:

a turbine comprising:
a rotor which has a plurality of rotor blades, and which is rotatably bearing-supported for rotation around a rotor rotation axis;
and
a generator for generating electrical power, the generator being connected to the rotor;
and
a turbine carrier which receives the turbine, the turbine carrier being rotatably arranged at a supporting structure,
wherein the turbine is movably mounted in the turbine carrier by a bearing device so that the spatial position of the turbine in the turbine carrier can be modified;
wherein a pivoting range of the turbine, corresponding to a pivoting range of the rotor rotation axis, includes a first angle range, in which the turbine is pivoted when the wind power installation is in operation, and a second angle range, in which the turbine is pivoted when the wind power installation is not in operation, relative to a horizontal reference plane, with the total angle range of the pivoting range being at least 120°;
wherein the turbine carrier and the turbine include a pivoting device configured to pivot the turbine around the second angle range when the wind power installation is not in operation;
and
wherein the turbine carrier has a further bearing device in which the turbine is rotatably mounted temporarily during pivoting in the pivoting range according to the second angle range.
