HYDROELECTRIC POWER SYSTEM AND TURBINE IN PIPE Russian patent published in 2014 - IPC F03B7/00 F03B3/12 F03D3/00 

FIELD: power engineering.

SUBSTANCE: invention is related to the field of hydroelectric generation of power. A spherical turbine 96 is made for rotation in transverse direction in a cylindrical pipe under action of a working substance flowing through the pipe in any direction. The turbine 96 is in working condition connected with a rotary machine or generator for power generation. In one example of realisation the blades 112, 114, 116, 118 of the spherical turbine 96 are arched approximately by 180 degrees in the plane, which is inclined at the angle relative to the axis of rotation of a central shaft 64. In the other example of realisation inside the cylindrical pipe there is a deflector along the upstream of the spherical turbine 96 to control the flow via the spherical turbine 96 by screening of the part of this flow.

EFFECT: blades 112, 114, 116, 118 of the spherical turbine 96 have in cross section an aerodynamic profile for optimisation of hydrodynamic flow, to minimise cavitation and to maximise axial energy conversion into rotation energy.
