Abstract
A vertical axis wind turbine includes a cylindrical rotor with a plurality of convex-concave blades placed in a stator which directs the wind stream. The VAWT is installed vertically towards a surface of the ground, and wherein, the stator and the rotor are formed of vertically located blades which may have numerous geometric forms. Both the stator and rotor blades have a leading edge and a trailing edge, and each blade of the stator possesses a top end that is fastened to an immobile upper plate of the stator, and a bottom end that is fastened to a lower plate of the stator. In this embodiment, each blade of the rotor includes a top end fixed to an upper plate, while a bottom end of the each blade is fixed to a lower plate.
Claims19
A vertical axis wind turbine (VAWT) comprising:
- a set of rotor blocks arranged on a vertical axis, wherein each individual rotor block is interconnected through a set of screws;
- a flanged shaft, wherein an end of the uppermost rotor block is fixed to the flanged shaft through a set of flanged shaft screws;
- a tube contained within the set of rotor blocks, wherein the tube receives the flanged shaft and extends from a top of the uppermost rotor block to a bottom of a lowermost rotor block and is connected via a set of flange shaft bolts to a butt of a wind turbine flanged shaft;
- a body, wherein the body is fixed on a foundation ring via a set of foundation bolts;
- a body cover connected to the body and the lowermost rotor block;
- a rotatory column installed in a center of the body and fixed on a lubricated support bearing to enable rotation of the rotatory column wherein the final regulation of the rotatory column along the vertical axis is accomplished through a compensation ring;
- a set of stator blocks, wherein the set of stator blocks surround the set of rotor block and are interconnected through the set of screws and are motionlessly connected to a closure head through the set of screws;
- a foundation to support the set of rotor blocks and set of stator blocks;
- a set of rotor blades contained within each rotor block, wherein each rotor blade comprises a leading edge and a trailing edge;
- a set of stator blades contained within each stator block, wherein each stator blade comprises a leading edge and a trailing edge;
- and
- wherein a surface of each rotor blade is made respectively of a top (positive) part of the rotor's blade edgy profile, and a surface of each stator blade is made respectively of a bottom (negative) part of the edgy profile, deposed along a horizontal axis and the blades are placed along the rotor and stator radius evenly on one line in the horizontal plane and with a minimal gap in the vertical plane and the leading edge of the rotor blade surface is the continuation of the trailing edge of the stator blade surface that an edgy profile butt is formed on one axial line along the radius in a static position and the stator and rotor blades are perpendicular to the rotation axis along with having an identical length and equal in quantity.
