Patent

CA 2734085

The invention relates to a seat portion structure (10) for a ground-based hydraulic turbine engine (50). The seat portion structure includes a base plate (12). A first bearing element (20) is connected to the base plate and contacts the ground. At least three arms (26) are connected to the base plate by a pivoting link (28). The arms are adapted for pivoting relative to the base plate between a first position, in which the arms are placed near each other, and a second position, in which the arms radially extend from the base plate (12). A second bearing element (30) is connected to one end of each arm and contacts the ground. A positioning device (32) is adapted for changing the distance between the end of at least one arm and the associated second element. The structure includes, for each arm, a device (36) for locking the arm in the second position.

L'invention concerne une structure d'assise (10) d'une turbomachine hydraulique au sol (50). La structure d'assise comprend un radier (12). Un premier élément d'appui (20) est relié au radier et est en contact avec le sol. Au moins trois bras (26) sont reliés au radier par une liaison pivotante (28). Les bras sont adaptés à pivoter par rapport au radier entre une première position dans laquelle les bras sont rapprochés les uns des autres et une seconde position dans laquelle les bras s'étendent radialement depuis le radier (12). Un second élément d'appui (30) est relié à une extrémité de chaque bras et est en contact avec le sol. Un dispositif de positionnement (32) est adapté à modifier la distance entre l'extrémité d'au moins un bras et le second élément d'appui associé. La structure comprend, pour chaque bras, un dispositif de blocage (36) du bras dans la seconde position.
