Device for maintaining a hydraulic turbomachine

A device for holding a hydraulic turbomachine in position, the turbomachine comprising a drive shaft along which are distributed turbines designed to rotate the drive shaft when they are immersed in a moving liquid, each turbine comprising drive blades distributed around the drive shaft, the device comprising:

• at least three posts extending along at least more than half of the length of the drive shaft, each post being formed of the stacking of at least two post portions, each post portion being associated with a turbine or with an assembly of adjacent turbines, at least two posts being designed to be arranged upstream of the turbomachine along the liquid flow direction and on either side of a plane containing the axis of the drive shaft and the liquid flow direction;
• first linking means attached to one of the post portions and to a bearing receiving the drive shaft and arranged between two adjacent turbines;
• and
• second linking means connecting at least one of the posts to the ground by a rigid connection with respect to the ground along at least one axis parallel to the liquid motion direction;
• said device comprising at the level of each post portion among two post portions of said two posts arranged upstream of the turbomachine, associated with a same turbine or with a same assembly of adjacent turbines, a conditioning device attached to said post portion or integrated with said post portion of each of said two posts and capable of directing the liquid flow towards the turbomachine, said conditioning devices being symmetrical with respect to the liquid flow direction.
