POWER-GENERATING SET EXPLOITING FLUID FLOW ENERGY Russian patent published in 2009 - IPC F03B9/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to water-power engineering, particularly to power plants driven from a fluid flow energy, and can be used for transforming fluid flow power, e.g. that of river streams, into electrical power. The proposed power-generating set comprises a bearing carcass with an action turbine incorporating two vertical shafts running therein with their edges accommodating drive wheels interconnected by lower and upper flexible pull elements between which blades are arranged to foam a closed conveyor located across the fluid flow. The blades working surfaces are arranged at an angle to the flow direction. Note that the conveyor has sliding supports interacting with the guides provided in the carcass upper and lower supports. The carcass accommodates electric generator linked up with one of the conveyor shafts. The said blades represent vertical triangular prisms with their bases being isosceles triangles and the angle at the apex being oriented in one direction. The said sliding supports and every prism are rigidly coupled, by their bases, with appropriate upper and lower pull elements.

EFFECT: higher speed of conveyor and increase power output.
