WIND THERMAL PLANT Russian patent published in 2007 - IPC F03D9/00 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind plants converting kinetic energy of wind into thermal energy, and it can be used in water heating systems. Plant contains windwheel with blades, shaft, windwheel installed for axial movement on axle of rotation, friction heat generator installed on rotary device of support design and branch pipes connected with external heat mainline. Heat generator has conical rotor installed in shaft in housing with inner conical surface. Hollow housing consists of two parts, cylindrical one and conical one, taper being 0.5-1.0°. Clearance is made between like end faces of rotor and its housing pointed to windwheel. Side surface of rotor is provided with spiral groove over entire length, and end face of rotor from side opposite to place of connection of rotor and shaft is provided with two pins over circumference of cross section of rotor. Pump piston is installed in space of cylindrical part of housing. Side cylindrical surface of piston has zigzag slot for engagement with projections on inner part of side surface of cylindrical part of housing. Piston is made with through holes for oil and for axial shifting of piston relative to rotor. End face of piston opposite to rotor has check valve connected with piston for travel relative to piston forming clearance together with wall of piston part of housing. Inlet and outlet branch pipes are arranged in rotor and piston parts of housing, respectively.

EFFECT: improved reliability provision of effective operation, increased service life.
