The invention relates to a wind turbine having at least one measuring device for measuring deformations of an elongated component of the wind turbine, such as a tower or a rotor blade. The measuring device is part of a transmitting/receiving device with a remotely arranged reflector device, is mounted in a bracket, and has adjusting devices for precise adjustment and alignment of the measuring device relative to the bracket. The adjusting device has a cam rotation device at the bearing point of the adjusting device. The cam rotation device has, at every bearing point, a cam disc with an adjusting wheel, at least one ball disc with an associated ball socket and a clamping screw. The invention also relates to a method for adjusting and aligning a measuring device of the wind turbine, wherein the measuring device is aligned in the horizontal and vertical direction by rotating the cam rotation device.

Wind turbine having a measuring device

The invention relates to a wind turbine comprising a rotor hub () rotating about a rotor axis (), rotor blades () extending radially with respect to the rotor axis () at the same angular spacing relative to one another, and a remote wind gauge () that is fastened externally on the surface of the hub () in a mounting () and oriented such that wind characteristics at a distance in front of the hub () can be ascertained or measured, wherein the remote wind gauge () is arranged between two neighbouring rotor blades () and in the radial direction of the rotor axis () and the mounting () is fastened to a respective blade bearing flange () in the region of the connection of the rotor hub () to the rotor blades (), such that the remote wind gauge () can be retrofitted to the wind turbine ().

Wind turbine having a remote wind gauge

A sensor device for measuring aerodynamic loads of a rotor blade for a wind power installation. The sensor device includes a reflector arranged in a cavity of the rotor blade which signals a signal evaluation device arranged at a distance from the reflector. The signal evaluation device detects and quantifies physical changes of the rotor blade from the reflected signal. A cleaning device for the reflector is arranged on the reflector for activation by a centrifugal force generated during the rotation of the rotor to clean the reflector.
