Das bisher übliche Verfahren, Hubbühnen, Hubsteiger oder Krane zu verwenden, ist teuer, insbesondere bei Offshore-Windenergieanlagen ist der Einsatz solcher Geräte problematisch und meist wegen Wellengangs, Nebel oder dgl. unmöglich. Ein weiteres Problem stellen die zunehmenden Nabenhöhen dar.The usual method to date of using lifting platforms, cherry pickers or cranes is expensive. The use of such equipment is particularly problematic for offshore wind turbines and is usually impossible due to waves, fog or similar. Another problem is the increasing hub heights.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Prüfung und Wartung der Rotorblätter einer Windenergieanlage zu schaffen, die von der Windenergieanlage selbst betrieben werden kann.The invention is based on the object of creating a device for testing and maintaining the rotor blades of a wind turbine, which can be operated by the wind turbine itself.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vorrichtung mit einem Rahmen mit zwei gelenkig miteinander verbundenen Schenkeln, die jeweils mit mindestens zwei Führungsrollen und Sensoren versehen sind und einem Halteband, das an beiden Schenkeln befestigt ist und bei Verwendung um das Rotorblatt gelegt wird, wobei an einem der Schenkel eine zum Spannen des Haltebandes dienende Einrichtung vorgesehen ist.According to the invention, this object is achieved by a device with a frame with two articulated legs, each of which is provided with at least two guide rollers and sensors, and a retaining strap which is fastened to both legs and is placed around the rotor blade when in use, wherein a device for tensioning the retaining strap is provided on one of the legs.

Die Unteransprüche geben bevorzugte Ausgestaltungen der Erfindung an.The subclaims specify preferred embodiments of the invention.

Die hier vorgeschlagene Vorrichtung kann durch bei horizontal stehenden Blättern, selbsttätig auf dem Rotorverfahren (bei dieser Ausführungsform sind die Führungsrollen antreibbar, bevorzugt ist jedoch eine Ausgestaltung, bei der die Vorrichtung bei vertikalstehendem Rotorblatt von der Nabe über ein Seil abgehängt wird und so in der Höhe bewegt werden kann.The device proposed here can be moved automatically on the rotor when the blades are horizontal (in this embodiment the guide rollers are drivable, but a preferred embodiment is one in which the device is suspended from the hub via a cable when the rotor blade is vertical and can thus be moved in height.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt:The invention is explained below with reference to a drawing.

In Fig. 1 ist die Vorrichtung gezeigt, wie sie mit dem - im Schnitt dargestellten - Rotorblatt 20 zusammenwirkt.In Fig. 1, the device is shown as it interacts with the rotor blade 20, shown in section.

Die Vorrichtung besteht aus einem Rahmen, der durch zwei Schenkel 10, 12 gebildet ist. Die Schenkel sind an ihren einen Enden gelenkig miteinander verbunden. An den beiden Schenkeln 10, 12 ist weiter ein Halteband 18 befestigt, einer der beiden Schenkel 12 ist mit einer zum Spannen des Haltebandes dienenden Einrichtung 22 versehen.The device consists of a frame formed by two legs 10, 12. The legs are connected to one another in an articulated manner at one end. A retaining strap 18 is also attached to the two legs 10, 12, and one of the two legs 12 is provided with a device 22 for tensioning the retaining strap.

Fig. 2 zeigt, wie die Vorrichtung von einer Nabe einer Windenergieanlage an einem Tragseil 22 an dem vertikal stehenden Rotorblatt geführt wird. Bei einer beabsichtigten Bewegung des Rotorblatts in vertikaler Richtung wird zunächst das Halteband 18 gelockert, die Vorrichtung kann jetzt frei weiter abgelassen oder wieder zur Nabe herangeführt werden, indem das Tragseil 22 angezogen oder weiter abgelassen wird. Bei Erreichen der gewünschten Position wird das Halteband 18 wieder gespannt, die Führungsrollen sitzen fest an dem Rotorblatt an.Fig. 2 shows how the device is guided from a hub of a wind turbine on a support cable 22 on the vertically positioned rotor blade. When the rotor blade is to move in a vertical direction, the retaining band 18 is first loosened, the device can now be freely lowered further or brought back to the hub by tightening or further lowering the support cable 22. When the desired position is reached, the retaining band 18 is tightened again and the guide rollers sit firmly on the rotor blade.

Die Führungsrollen 14 wirken dabei, dass ein Mindestabstand zwischen Rotorblattfläche und der den Rahmen bildenden Schenkel 10, 12 gewährleistet ist.The guide rollers 14 ensure that a minimum distance is maintained between the rotor blade surface and the legs 10, 12 forming the frame.

Die Schenkel 10, 12 sind mit Sensoren 16 versehen, die geeignet sind, Beschädigungen des Blattes zu erkennen. Dabei kann es sich um optische Sensoren, aber auch um sonstige Sensoren handeln, die dazu in der Lage sind, Unregelmäßigkeiten in der Fläche der Rotorblätter zu erkennen.The legs 10, 12 are provided with sensors 16 that are suitable for detecting damage to the blade. These can be optical sensors, but also other sensors that are able to detect irregularities in the surface of the rotor blades.

Über ein Daten- und Versorgungskabel 24 wird die Vorrichtung 24 mit Energie und Steuerbefehlen versorgt, die erfassten Daten werden über das Kabel 24 zu einer Auswerteeinheit in der Windenergieanlage geführt.The device 24 is supplied with energy and control commands via a data and supply cable 24, and the recorded data is fed via the cable 24 to an evaluation unit in the wind turbine.
