FLOATING HYDROELECTRIC POWER PLANT WITH UNDERWATER TURBINE Russian patent published in 2006 - IPC F03B9/00 F03B13/00 F03B17/06 

FIELD: conversion of river stream energy into electric power.

SUBSTANCE: proposed plant has base in the form of catamaran that mounts current generators and their drive, current parameters stabilizing system, turbine capable of running in fully submerged condition, and its hoist. Turbine is made in the form of belt conveyer installed on edge at certain angle to river stream. Blades made of flexible material are secured throughout entire width and length of belt. Each blade is made in the form of bucket capable of folding and resting on belt during transfer from working to idle side of conveyer, and it has pocket on external surface for automatic raising of blade by river stream during transfer from idle to working position. Turbine hoist has rocker arm for turbine suspension hinged on one end to catamaran and on other end, to turbine frame that mounts generator-drive bevel gear so that longitudinal axes of hoist rocker-arm hinges and longitudinal axis of bevel-gear driven pinion are disposed on same line. In addition, hydroelectric power plant is equipped with device enabling variation of turbine angle of installation to water flow.

EFFECT: enhanced power capacity.
