The quality of rotor blades for wind turbines for electricity generation is determined by factors such as profile accuracy, surface quality, wall thickness, elasticity, moisture absorption and so on.
Weiter unterliegen die Rotorblätter unterschiedlichen Witterungs- und Belastungseinflüssen, die zu Schäden an der Oberfläche wie Delaminierungen oder Haarrissbildung auch in der Materialtiefe führen können.Furthermore, the rotor blades are subject to different weather and load influences, which can lead to damage to the surface such as delamination or hairline cracking even in the material depth.
Nach dem Stand der Technik werden insbesondere die Verschleißschäden durch geschultes Personal erkannt und begutachtet, indem mit einem Hammer auf das Rotorblatt geklopft und der Klang des Klopfgeräusches bewertet wird.According to the prior art, wear and tear in particular is recognized and assessed by trained personnel by tapping the rotor blade with a hammer and evaluating the sound of the knocking noise.
Nachteilig an diesem Verfahren sind die langen Stillstandszeiten der Windkraftanlagen, die zu Stromproduktionsausfällen führen sowie die aufwändige Methode, die Personal mit besonderen Fähigkeiten erfordert, wobei die Ergebnisse der Prüfung rein subjektiver Natur sind.Disadvantages of this procedure are the long downtimes of the wind power plants, which lead to power production failures, and the complex method, which requires personnel with special skills, the results of the test being purely subjective.
Insbesondere bei offshore betriebenen Windkraftanlagen ist der Aufwand, eine Person vor Ort zu bringen, die die Untersuchungen durchführt, unverhältnismäßig hoch.In the case of offshore wind turbines in particular, the effort to bring a person on site to carry out the investigations is disproportionately high.

Die Energieversorgung des Carriers (zum Beispiel Akku) kann in der Parkstation automatisch aufgefrischt werden. In der Parkstation kann auch eine automatische Funktionskontrolle der einzelnen Aggregate und Sensoren des Carriers erfolgen, wobei das Ergebnis dieser Funktionskontrolle der Wartungs- oder Einsatzmannschaft in geeigneter Form automa- tisch mitgeteilt wird, um ein unnötiges Aufsetzen eines defekten Carriers auf ein Rotorblatt auszuschließen.The energy supply of the carrier (e.g. battery) can be refreshed automatically in the parking station. An automatic function check of the individual aggregates and sensors of the carrier can also take place in the parking station, the result of this function check of the maintenance or emergency team in a suitable form being automated. table is communicated to rule out unnecessary placement of a defective carrier on a rotor blade.

Für das Aufsetzen auf ein waagerecht stehendes Rotor- blatt kann der Carrier zangenförmig ausgebildet sein, wobei die Zange sich nach dem Absetzen auf dem Rotorblatt automatisch schließt und beim Wiederaufnehmen durch den Hubschrauber automatisch öffnet, wobei der Schließ- und Öffnungsvorgang auch manuell gesteuert erfolgen kann.The carrier can be designed in the form of pliers for placement on a horizontal rotor blade, the pliers automatically closing after being placed on the rotor blade and opening automatically when the helicopter resumes them, the closing and opening process also being able to be carried out manually.
Zur Reduktion von Pendelbewegungen während des Abset- zens auf dem Rotorblatt kann eine gyrokinetische Stabilisierung durch einen Schwerekreisel oder durch eine aktive Pendelstabilisierung über eine Regelstrecke vorgesehen sein.In order to reduce pendulum movements during settling on the rotor blade, gyrokinetic stabilization by means of a gyroscope or by active pendulum stabilization over a controlled system can be provided.
Die Energieversorgung des Carriers wird entweder autark durch zum Beispiel Akkumulatoren oder Brennstoffzellen hergestellt oder per Kabel vom Trägerfahrzeug aus. Weiter können Wärmeenergieträger in Form fossiler Brennstoffe mit- geführt werden, oder kinetische Energie in Form von Druckluft oder Schwerekreiseln.The carrier's energy supply is either self-sufficient, for example, by means of batteries or fuel cells, or by cable from the carrier vehicle. Furthermore, thermal energy sources in the form of fossil fuels can be carried, or kinetic energy in the form of compressed air or gravity gyros.
Der Antrieb des Carriers zur Fortbewegung auf dem Rotorblatt geschieht vorteilhaft über Reibräder oder Reibriemen nach dem Raupenprinzip.The drive of the carrier for locomotion on the rotor blade advantageously takes place via friction wheels or friction belts based on the caterpillar principle.
Wenn der Carrier von einem Schiff (bei Offshore- windkraftanlagen) oder bei landgestützten Windkraftanlagen vom LKW aus von unten an ein Rotorblatt angesetzt wird, kann eine angepasste Hubeinrichtung auf dem Trägerfahrzeug vorgesehen sein, die den Carrier von unten an das Rotor- blatt heranführt.

The carrier then moves up or down the rotor blade automatically or remotely.
Im Falle einer auftretenden Störung, die es dem Carrier nicht mehr ermöglicht zur Übernahmeposition für das Trägerfahrzeug zurückzukehren, ist eine Notausklinkung vorgesehen, die es erlaubt, den Carrier von jeder beliebigen Stelle des Rotorblattes aus wieder aufzunehmen.In the event of a malfunction that no longer enables the carrier to return to the takeover position for the carrier vehicle, an emergency release is provided which allows the carrier to be picked up again from any point on the rotor blade.
Der innere Querschnitt des Carriers kann vorteilhaft rotorblattformspezifisch oder universell ausgelegt sein. Eine Anpassung an das jeweilige Rotorblattprofil kann dann durch eine geeignete Versteilvorrichtung oder durch geeignete Adapter erfolgen.The inner cross section of the carrier can advantageously be designed to be specific to the rotor blade shape or to be universal.
