MEDIUM FLOW ENERGY CONVERTING DEVICE Russian patent published in 2006 - IPC F03D5/00 

FIELD: power engineering.

SUBSTANCE: invention relates to devices converting energy of medium flow, such as wind or water, and it can be used in wind power engineering, particularly, in wind power generating plants. Proposed device contains load-bearing support with shaft, planetary mechanism with housing containing pair of coaxial bevel gears installed on axle-shafts and provided with two toothed rims, pair of coaxial bevel gears having one toothed rim each, and central bevel gear. Larger toothed rims of first pair of bevel gears are equal in size to toothed rim of central bevel gear being in meshing with said gear, and smaller toothed rims of first pair of bevel gears are equal in size with rims of second pair of bevel gears being in meshing with the latter. Each paired bevel gear has coaxial driven shaft with flange. Rotary blade is secured on each flange square to driven shaft. Second rotary blade is secured on each flange additionally square to first blade being orientated in opposite direction relative to first blade.

EFFECT: improved efficiency of plant owing to provision of combined coordinated synchronous operation of several rotary blades, improved efficiency of utilization of energy of medium flow.
