AUTOMATED ARCHITECTURAL-TECTONIC WINDMILL Russian patent published in 2014 - IPC F03D7/00 

FIELD: power engineering.

SUBSTANCE: proposed windmill comprises vertical shaft, rotor with vertical rotational axis and semi-cylinder shield in height larger than or equal to rotor height while shield inner radius is larger than rotor radius. Besides, said windmill comprises architectural structure with hip-roof located thereon. Roof base is shaped to inversed hollow truncated cone fixed at vertical shaft. Said shaft is fixed at architectural structure and on cylindrical support columns. Said column are arranged regularly over the roof in circle relative to vertical shaft, its diameter being larger than rotor diameter. One of said vertical columns is composed of drive shaft running in thrust bearings. It is equipped with mechanism of motion transfer to said shield via flexible drive mechanisms supporting said shield. Other cylindrical columns are equipped with shield flexible drive support assemblies. Said rotor runs in bearings on vertical shaft. Besides, windmill comprises control system including wind speed and direction metre, control unit, setting unit, generator, power transducer, power consumers, shield drive, shield position metre and shield position transducers. Rotor bearing and power takeoff assembly is connected with control unit first input. Setting unit output is connected to second input. Wind speed and direction metre output is connected to control unit third input. Shield position metre output is connected to control unit fourth input. Control unit output is connected via shield drive with shield position metre input, shield drive second output being connected with drive shaft. Shield position metre second input is connected to combined outputs of the shield position transducers.

EFFECT: higher reliability and accuracy of power output control.
