WIND-DRIVEN POWER PLANT Russian patent published in 2020 - IPC F03D3/04 E04H12/28 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind-driven power plant comprises a vertical pipe formed of following sections one after another: installed on the foundation of the lower confuser section with a heating element and with air intake openings, middle cylindrical and upper diffuser sections, turbine and electric generator arranged in the middle cylindrical section of the pipe, as well as a deflector with a pipe located above the outlet mouth of the pipe. Wind-driven power plant is additionally equipped with shaped elements enveloping the pipe sections and assembling the sectional-assembled mesh tower mounted on the foundation, which is the power frame of the plant, cables connecting central part of bearing tower with foundation, air flow rate regulating the air flow coming out of the pipe, made in the form of a disk ring with movable servo-driven segments and installed in the mouth of the diffuser section of the pipe with attachment to the shaped elements enclosing the diffuser section of the pipe, air flow velocity sensor installed in middle cylindrical pipe section upstream of turbine, control unit connected to servo drive of air flow rate regulator outputting from pipe, and with air flow velocity sensor, as well as confuser inserts installed in air openings of lower confuser section of pipe. Turbine has blades and shaft installed in bearings, fixed to shaped elements of middle section of bearing tower, and connected to shaft of electric generator. Sections of the pipe are detachable and fastened to each other and to sections of the bearing tower. Pipe is installed on the foundation so that its outlet mouth can be located at height of 50–150 m. Deflector is fixed to shaped elements of bearing tower.

EFFECT: invention is aimed at stabilization of load on turbine and associated electric generator and hardening of structure.
