EXHAUST DEVICE FOR WIND-DRIVEN POWER PLANT (VERSIONS) Russian patent published in 2009 - IPC F03D11/00 

FIELD: engines and pumps.

SUBSTANCE: invention is related to the field of wind power engineering, in particular to exhaust devices of wind-driven power plant, and is intended for reduction of resistance to wind flow that exits upper section of vertical channel diffuser. In preferable version of invention exhaust device of wind-driven power plant comprises the first surface of wind flow direction (WFD), which is located around diffuser, and is arranged along height in the form of at least one tier of separate first surfaces of WFD fixed on frame with the possibility of their rotation around their horizontal axes, in their lower part, for provision of wind flow direction above higher open section of mentioned diffuser from the side of wind flow and their rotation along wind flow from back side. In other version of invention the first surface of WFD is arranged along height in the form of at least one tier of separate elastic surface of WFD with reverse cone shape for its pressing with wind flow from one side to frame and its release down b wind flow on the other side of mentioned frame.

EFFECT: lower inertia of exhaust device changeover into stable working mode of external wind flow deviation above upper open part of vertical channel diffuser in case of vertical channel diffuser height lowering.
