| 摘要 |
The invention relates to a wind turbine having at least one measuring device (28) for measuring deformations of an elongated component of the wind turbine (1), such as a tower or a rotor blade. The measuring device (28) is part of a transmitting/receiving device with a remotely arranged reflector device (25), is mounted in a bracket (35), and has adjusting devices (41, 38) for precise adjustment and alignment of the measuring device (28) relative to the bracket (35). The adjusting device (41, 38) has a cam rotation device (41) at the bearing point of the adjusting device. The cam rotation device (41) has, at every bearing point, a cam disc (46) with an adjusting wheel, at least one ball disc (44) with an associated ball socket (45) and a clamping screw (43). The invention also relates to a method for adjusting and aligning a measuring device of the wind turbine (1), wherein the measuring device (28) is aligned in the horizontal and vertical direction by rotating the cam rotation device (41). |

1. Wind turbine with a rotor (6), having at least one rotor blade (9,10,18) extending perpendicularly to the rotor axis (7), a nacelle (4) that is stationary relative to the rotor (6), supported by a tower (3), and with at least one measuring device (28) for measuring deformations of one or more elongated components of the wind turbine (1), wherein the measuring device (28) is arranged in a cavity (24) within a component of the wind turbine (1), is part of a transmitting/receiving device with a remotely arranged reflector device (25), is mounted in a bracket (35), secured on opposite sides of the cavity (24), and adjusting devices (41, 38) for precise adjustment and alignment of an alignment face (34) of the measuring device (28) relative to the bracket (35),
characterised in that the adjusting device (41, 38) has a cam rotation device (41) at its bearing point, by means of which the measuring device (28) is supported in the bracket (35), and by rotating the cam rotation device (41) the measuring device (28) can be aligned and adjusted relative to its alignment face (34), wherein the cam rotation device (41) has, at every bearing point, a cam disc (46) with an adjusting wheel, at least one ball disc (44) with an associated ball socket (45) and a clamping screw (43), and the measuring device (28) is enclosed by a housing (33), which in the longitudinal direction is mounted on mounting flanges (37) arranged opposite each other on the faces of the bracket (35) and is part of the alignment face (34) of the measuring device (28). |
