Abstract

L'invention concerne des pylônes autoporteurs supportant une éolienne, dans lesquels peuvent être agencés, au-dessous de l'éolienne, une ou plusieurs poutres transversales auxquelles des câbles conducteurs et des câbles de terre sont suspendus ou sont supportés par celles-ci, pour le transport de courant à moyenne ou haute tension. L'éolienne peut être montée basculante en position de transport et/ou déplaçable, au pied du pylône ou à son emplacement d'exploitation, et ses pales sont repliées (parallèlement ou le long de l'axe du rotor) pour prendre des dimensions aptes au transport, correspondant à l'espace du pylône autoporteur. L'éolienne peut être déplacée, sans démontage, à partir du pied du pylône vers son emplacement d'exploitation et, également, de son emplacement d'exploitation vers le pied du pylône. La solution selon l'invention présente un intérêt économique, du fait que de nombreuses pièces du dispositif de transport n'ont pas à demeurer sur le pylône, mais ne devront être amenées aux pylônes respectifs qu'en cas de besoin. D'autres avantages résultent de la double utilisation des pylônes autoporteurs et des emplacements, l'éolienne pouvant être déplacée devant les câbles conducteurs montés sur le pylône, sans venir en contact avec ces derniers, une coupure du courant n'étant, dès lors, plus requise.
