DEVICE FOR MAINTAINING A HYDRAULIC TURBOMACHINE

摘要

The invention concerns a device (50) for maintaining a hydraulic turbomachine (30), the turbomachine comprising a drive shaft (31) along which are distributed the turbines (10) for driving the drive shaft in rotation when they are immersed in a moving liquid, each turbine including motoring blades (14) distributed around the drive shaft. The device comprises at least one post (52) oriented along the axis (D) of the drive shaft and consisting at least of two superimposed post portions (42), each post portion being associated with a turbine or with an assembly of adjacent turbines, and first linking means (44) fixed to one of the post portions and to a bearing (46) receiving the drive shaft arranged between two adjacent turbines and second linking means connecting at least one of the posts to the floor.
