Abstract[English]
A nacelle for a wind turbine comprises a nacelle housing for housing components of a wind turbine and a nacelle cover. The nacelle housing comprises a nacelle opening. The nacelle cover is arranged over the nacelle opening, and is movable between a closed position in which the nacelle opening is fully covered by the nacelle cover, and an open position in which the nacelle opening is at least partially uncovered to allow access to components housed within the nacelle housing. The nacelle cover comprises multiple cover panels arranged telescopically with respect to one another, wherein at least one cover panel is movable with respect to another cover panel along a longitudinal axis of the nacelle to move the nacelle cover between its open and closed positions.[French]
L'invention concerne une nacelle destinée à une éolienne et comprenant un logement de nacelle pour loger des composants d'une éolienne et d'un capot de nacelle. Le logement de nacelle comprend une ouverture de nacelle. Le capot de nacelle est disposé au-dessus de l'ouverture de nacelle, et est mobile entre une position fermée dans laquelle l'ouverture de nacelle est complètement recouverte par le capot de nacelle, et une position ouverte dans laquelle l'ouverture de nacelle est au moins partiellement découverte pour permettre l'accès à des composants logés dans le logement de nacelle. Le couvercle de nacelle comprend de multiples panneaux de couverture disposés de manière télescopique les uns par rapport aux autres. Au moins un panneau de couverture est mobile par rapport à un autre panneau de couverture le long d'un axe longitudinal de la nacelle pour déplacer le capot de nacelle entre ses positions ouverte et fermée.
