WIND TURBINE WITH N BLADED PROPELLERS Russian patent published in 2024 - IPC F03D1/02 F03D7/02 F03D15/00 

FIELD: electricity.

SUBSTANCE: invention relates to renewable energy, in particular to wind power engineering, and can be used as a source of electric energy. Windmill comprises bladed propellers in vertical plane and is made with possibility of self-installation in direction of wind flow. Axes of blade propellers are fixed on horizontal sections of rectangular frame of basic structure by means of bearings. Working sprockets are fixed behind the basic structure at the ends of these axes. In the upper corners of the rectangular frame of the basic structure the axes of the guide sprockets are fixed with the help of bearings, and at the lower corners the longer axes with the generator sprockets are connected through the couplings to the generator units, the outputs of which are connected to the consumer network. All sprockets of windmill are combined by means of chain transmission, the latter is fixed on top of all sprockets of windmill, except for generator ones, which are covered by chain transmission from below. Basic structure is installed on the rail ring and rests on three wheels, two guide wheels are located on the lower section of the rectangular frame and directly on the diameter of the rail ring, and the third support wheel in the middle of the rail semi-circle between them on the part of the base structure located perpendicular to the rectangular frame at the centre of its lower part.

EFFECT: guide wheels are electrically driven and by commands from control unit connected to set of sensors, base structure is set relative to wind direction so that blade screws are in vertical plane perpendicular to wind direction.
