HYDRAULIC POWER PLANT Russian patent published in 2012 - IPC F03B13/10 F03B7/00 

FIELD: power engineering.

SUBSTANCE: hydraulic power plant is a floating facility fixed by cables 2 with supports 3 on the shore, comprising one row and more turbines 4, installed in parallel on hollow platforms 7, changing into sharp edges along the vertical line in a fore part. Shafts of turbines 4 are installed in bearing supports 6 as capable of vertical displacement and are kinematically connected to a power generator 8 and starting-regulating equipment 9. There are sprockets 14 installed on shafts of turbines 4 and connected by chains 15 to each other. Upstream the floating facility 1 there is a filter 19 in the form of a wedge for discharge of objects. Blades of turbines 4 are crescent-shaped and are fixed to bodies of shafts so that their edges form a sharp angle with a water mirror. Hollow platforms 7 have a trapezoidal shape in their cross section, changing into sharp edges along the vertical line in a rear part. Vertical stands 20 of the filter 19 installed fixedly at a distance from the floating facility 1 are equipped with rollers as capable of cranking. The power generator 8 and the starting-regulating equipment 9 are installed on the shore.

EFFECT: higher efficiency, safety of operation and maintenance of a power plant.
