Wind turbine having a measuring device

1. A wind turbine with a rotor, comprising at least one rotor blade extending perpendicularly to a rotor axis, a nacelle that is stationary relative to the rotor, supported by a tower, and with at least one measuring arrangement for measuring deformations of one or more elongated components of the wind turbine, wherein the at least one measuring arrangement comprising:

a camera enclosed in a housing, a reflector arranged remotely from said camera, wherein the camera and reflector are arranged in a cavity within the one or more elongated components of the wind turbine, wherein the camera and housing are mounted in a bracket and the reflector is secured on an opposite side of the cavity, and

the at least one measuring arrangement further comprising:

adjusting devices for precise adjustment and alignment of an alignment face of the housing relative to the bracket; and each of the adjusting devices has a cam rotation device at its bearing point which supports the camera and housing to the bracket, and by rotating each said cam rotation device the alignment face is aligned and adjusted relative to the bracket, wherein each said cam rotation device has, at its associated bearing point, a cam disc with an adjusting wheel, at least one ball disc with an associated ball socket and a clamping screw, and the housing is mounted in the longitudinal direction on a pair of parallel facing mounting flanges of the bracket.

2. The wind turbine according to claim 1 , wherein the bracket is arranged in a stationary manner at an installation point of the at least one elongated component of wind turbine and the camera and housing can be set and adjusted relative to the bracket in the horizontal and/or vertical direction.

3. The wind turbine according to claim 1 , further comprising an adjusting screw with a lock nut.

4. The wind turbine according to claim 1 , wherein the bracket has a cutout, opposite the alignment face, and which the alignment face can penetrate into the cutout in full or in part.

5. The wind turbine according to claim 1 , wherein the elongated component of the wind turbine is the at least one rotor blade and/or the tower.

6. A method for forming a wind turbine, comprising:

providing the wind turbine having a rotor including at least one rotor blade extending perpendicularly to a rotor axis;

providing the wind turbine with a nacelle that is stationary relative to the rotor, supporting the nacelle with a tower;

placing within one of the elongated components of the wind turbine a transmitting/receiving device including a camera and a reflector arranged in a cavity of the one or more elongated components of the wind turbine, wherein the placing of the transmitting/receiving device further comprises;

arranging the reflector remotely from said camera, mounting the camera in a housing using a bracket secured on opposite sides of the housing;

using adjusting devices for precise adjustment and alignment of an alignment face of the housing relative to the bracket; and

configuring each of the adjusting devices to include a cam rotation device at a bearing point thereof, which supports the housing to the bracket, and such that rotating at least one of the cam rotation devices causes the alignment face to be moved to facilitate alignment and adjustment of the camera;

further configuring the cam rotation devices such that each has, at its associated bearing point, a cam disc with an adjusting wheel, at least one ball disc with an associated ball socket and a clamping screw, and mounting the housing longitudinally on a pair of parallel facing mounting flanges of the bracket.

7. The method according to claim 6 , wherein following alignment the cam discs are secured against rotation by means of the clamping screws.

8. The method according to claim 6 , wherein by rotating the two adjusting screws on the adjusting devices the measuring arrangement is set in the vertical direction and is secured by lock nuts.
