Abstract

L'invention concerne un système de nettoyage de pale d'éolienne et, plus particulièrement, un système de nettoyage de pale d'éolienne dans lequel une brosse est montée sur une partie de levage qui monte et descend le long d'une pale tout en étant soutenue par la tour de l'éolienne, la brosse étant formée pour faire saillie sur la circonférence interne de la partie de levage à travers laquelle passe la pale, pour amener en contact étroit la brosse rotative et la pale, de sorte que le système puisse éliminer, sans travail supplémentaire, les contaminants se trouvant sur la pale, selon le levage ou de l'abaissement de la partie de levage En outre, la brosse peut être tournée dans le sens vertical ou horizontal autour d'un cadre de support et présente ainsi une zone élargie en contact étroit avec la pale. Le système selon l'invention permet donc d'améliorer l'efficacité de nettoyage et de nettoyer des pales de formes diverses.
