Yaw adjustment of a wind turbine

Abstract

An adjusting device for adjusting a yaw position of a nacelle of a wind turbine, comprising a circumferential holed flange provided with drilled holes, and at least one adjusting means, having a gripping portion for gripping on the holed flange, a fastening portion for fastening to an anchorage point of the wind turbine, and a linear drive for exerting a linear movement between the gripping portion and the fastening portion, wherein the holed flange is fixedly connected to the nacelle, and the anchorage point is fixedly connected to stationary part of the wind turbine, in particular a wind turbine tower, or vice versa, and the nacelle is mounted so as to be rotatable relative to this stationary part of the wind turbine, such that the holed flange and the anchorage point can also execute a rotational movement relative to each other, such that a linear movement exerted between the gripping portion and the fastening portion by the linear drive effects a rotational movement between the holed flange and the anchorage point, and thereby effects a yaw adjustment of the nacelle, wherein the gripping portion has at least one movable fixing pin for engaging in respectively one of the drilled holes of the holed flange, in order thereby to fix the gripping portion to the holed flange in a releasable manner.
