Claims (11)
1. Fremgangsmåde til overvågning af strukturel tilstand af vindmøller i form af rotorer (1) med flere rotorblade (4), idet vindmøllerne overvåges af en eller flere termografiske registreringsanordninger (6) installeret på og/eller i en mobil placering (2), og de målte værdier derved evalueres med hensyn til eventuelle tilfælde af skader, som er kendetegnet ved, at de målte, bestemte værdier evalueres, samtidig med der tages hensyn til de termiske og/eller dynamiske belastninger forårsaget afdriften af rotorbladene (4) på tidspunktet for målingen.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved at data om de termiske og/eller dynamiske belastninger forårsaget på tidspunktet for målingen er sat i forhold til de målte, bestemte værdier.
3. Fremgangsmåde ifølge krav 2, kendetegnet ved, at de målte værdier er output, mens der tages hensyn til de relativiserede data.
4. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der tages hensyn til termiske belastninger som følge af friktion under driften af rotorbladene (4).
5. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der tages hensyn til de dynamiske belastninger forårsaget af rotationen af rotorbladene (4).
6. Fremgangsmåde ifølge krav 1, kendetegnet ved, at der tages særskilt hensyn til termiske og/eller dynamiske belastninger på grundlag af rotorbladets segmenter (4).
7. Fremgangsmåde ifølge krav 6, kendetegnet ved, at tolerancen i det mindste er lavet for de segmenter, der er forkanten (24), bladets område (25) og bagkanten (26).
8. Fremgangsmåde ifølge krav 1, kendetegnet ved, at et typecertificeret luftfartøj og/eller bemandet luftfartøj, som en helikopter (2), en ballon, en zeppeliner, en drage eller en drone anvendes som den mobile placering.
9. Fremgangsmåde ifølge krav 1, kendetegnet ved, at de termografiske optagelser fremstilles ved hjælp af dual-band infrarød teknologi.
10. Fremgangsmåde ifølge krav 1, kendetegnet ved, at rotorbladet (4) i sin helhed og/eller kun overfladen deraf overvåges ved stilstand eller under drift.
11. Fremgangsmåde ifølge krav 1, kendetegnet ved, at registrerede data ved scanning og termografisk eller terahertz-måling er sat i forhold til hinanden.
