The invention provides a wind power machine comprising a mast that is articulated so as to adopt an upright position above a foundation anchored into the ground and a folded-up position close to the ground. The mast is made up of substantially straight parts articulated together so as to pivot in order to bring the mast into the upright position or into the folded-up position. The wind power machine furthermore includes a locking device placed at at least one of the articulations between two of these parts in order to lock the mast in the upright position. The locking device (14) comprises: a radially movable clamping ring (1400), placed at the end of one of the two parts of said articulation (56) inside the mast; and actuation means (1401, 1403, 1405) that are capable of moving the clamping ring (1400) radially so as to produce an intimate male/female-type connection between the two parts of the articulation.
Eolienne comprenant un mât articulé de manière à prendre une position dressée au dessus d'une fondation ancrée au sol et une position repliée proche du sol. Le mât est composé de parties sensiblement rectilignes articulées entre elles de manière à pivoter pour amener le mât dans la position dressée ou dans la position repliée. L'éolienne comprend en outre un dispositif de blocage agencé à l'une au moins des articulations entre deux de ces parties pour verrouiller le mât dans la position dressée. Le dispositif de blocage (14) comprend : un collier de serrage (1400) mobile radialement, agencé à l'extrémité de l'une des deux parties de ladite articulation (56) à l'intérieur du mât; et des moyens d'actionnement (1401, 1403, 1405) aptes à déplacer Ie collier de serrage (1400) radialement de manière à réaliser un raccord étroit de type mâle/femelle entre les deux parties de l'articulation.
