Abstract

Dispositif d’obturation d’un conduit à éléments rigides déployables, système d’obturation et procédé d’installation associés L’invention concerne un dispositif d’obturation (10) étanche d’une ouverture d’un conduit comprenant : - un arbre central (12), et - un corps principal (14) comprenant au moins trois éléments rigides déployables (22). Chaque élément rigide déployable (22) est fixé à l’arbre central (12) à un sommet (24) respectif. Chaque élément rigide déployable (22) est relié à un élément d’actionnement (15), l’élément d’actionnement (15) étant déplaçable en translation le long de l’arbre central (12) de manière à déplacer les éléments rigides déployables (22) entre une position repliée et une position déployée dans laquelle le dispositif d’obturation (10) est apte à obturer un conduit. Le dispositif d’obturation (10) est apte à être maintenu dans le conduit par action des éléments rigides déployables (22) en position déployée sur le conduit. Figure pour l'abrégé : Figure 1
