Embodiment Construction

[0041] figure 1 A wind energy installation 100 is shown with a tower 102 , a nacelle 104 . Arranged on the pod 104 is a rotor 106 with three rotor blades 108 and a spinner 110 . The rotor blades 108 are connected to the figure 1 Shown in detail is a hub 112, which drives a generator 114 for generating electrical current. example in figure 1 Mounting of rotor blades 108 on hub 112 is shown in detail (A) of FIG. The rotor blade 108 is connected to a hub adapter 118 by means of a blade bearing 116 .

[0042] figure 2 To this end, a blade flange 10 is shown by way of example in view (A) and view (B) of a rotor blade 108 which, according to design, forms a holder as a first flange part. Also visible is a row of bolts 20 in the form of a plurality of screws or bolts on the blade flange 10 . The pegs 20 are arranged along the blade flange 10 in a concentrically surrounding row. The lower end of the blade flange 10 forms the holder for the flange connection. The bolt 20 is d...

Abstract

The invention relates to a flange connection device for a wind turbine, in particular a blade flange connection device. The flange connection device has a first flange part (10), in particular a blade receptacle of a rotor blade hub, a second flange part (30), in particular a rotor blade flange, and multiple bolts (20) which hold the second component (30) against the first flange part (10) in a connected state, wherein the bolts (20) are each screwed to the first flange part. It is proposed that the at least two bolts (20) are in each case connected to one another by a tension means (41), wherein a sensor arrangement (42, 42'), which detects a change in a tensile force (Fzug) transmitted by the tension means (41), is actively connected to the tension means (41). The wind turbine and a method for monitoring the flange connection device of the wind turbine are also proposed.

Description

technical field [0001] The invention relates to a flange connection, in particular a blade flange connection, of a wind energy installation, in particular a rotary component connection, comprising: a first flange part, in particular a blade receptacle of a rotor blade hub; a second flange part, especially the rotor blade flange; and a plurality of bolts, which hold the second flange part on the first flange part in the connected state, wherein the bolts are respectively screwed to the first flange part, and the invention relates to a Wind energy facility. Furthermore, the invention relates to a method for monitoring a flange connection. Background technique [0002] In the German patent application DE 10 2019 106 580.1 on the basis of priority, the following documents were searched by the German Patent and Trademark Office as prior art: DE 10 2015 212 906 A1, EP 3 467 303 A1. [0003] Flange connections of the type mentioned at the outset are known, for example, from wind ...
