HYDRAULIC TURBINE PLANT Russian patent published in 2003 - IPC

FIELD: hydroelectric stations. SUBSTANCE: invention relates to tidal power stations and low head river hydroelectric stations. Proposed plant contains at least two turbines horizontally-axially installed in water conduit, and one regenerator. Turbines are orthogonal cross-jet, their shafts being orientated across water conduit of plant which is divided at least by one pier into turbine conduits and are connected by kinematic coupling unit arranged in hermetically sealed space in pier body. Generator made with through shaft connecting shafts of turbines is used as kinematic coupling unit. Said unit can be made in form of additionally introduced step-up gear with through slow-speed connecting shafts of turbines. Kinematic coupling unit can include also generator made with through shaft and two additionally introduced step-up hears, high-speed shafts of step-up gears being connected by shaft of generator and slow-speed shafts, with shaft of corresponding turbine. Plant can be made in form of floatable unit-module of hydraulic structure. EFFECT: improved efficiency of usage of water flow energy. 7 cl, 2 dwg
