Abstract
A vertical axis wind turbine is disclosed. The wind turbine may include a polygonal mast having a predefined count of faceted sides. The polygonal mast may include a mast top end and a mast bottom end. The wind turbine may further include a drive shaft having a polygonal drive shaft top end and a drive shaft bottom end. The polygonal drive shaft top end may be configured to connect the mast bottom end with the drive shaft. The polygonal drive shaft top end too may have the predefined count of faceted sides.
Claims15
A wind turbine comprising:
- a polygonal mast having a first predefined count of faceted sides, wherein the polygonal mast comprises a mast top end and a mast bottom end;
- and
- a drive shaft comprising a polygonal drive shaft top end and a drive shaft bottom end, wherein the drive shaft bottom end is cylindrical, wherein the polygonal drive shaft top end is configured to connect the mast bottom end with the drive shaft, wherein the polygonal drive shaft top end has a second predefined count of faceted sides, wherein the first predefined count of faceted sides is same as the second predefined count of faceted sides, wherein a width of each polygonal mast faceted side is equivalent to a width of each polygonal drive shaft top end faceted side, and each faceted side of the polygonal drive shaft top end and the polygonal mast comprises through-holes that are configured to receive a first fastening mechanism to attach the mast bottom end with the polygonal drive shaft top end,
- wherein the drive shaft bottom end is configured to connect to a power generator, and wherein the drive shaft is configured to rotate axially when the polygonal mast rotates, which enables the power generator to generate electric power.
A vertical axis wind turbine comprising:
- a hexagonal mast comprising a mast top end and a mast bottom end;
- and
- a drive shaft comprising a hexagonal drive shaft top end and a drive shaft bottom end, wherein the drive shaft bottom end is cylindrical, wherein the hexagonal drive shaft top end is configured to connect the mast bottom end with the drive shaft, wherein a width of each hexagonal mast side is equivalent to a width of each hexagonal drive shaft top end side, and each side of the hexagonal drive shaft top end and the hexagonal mast comprises through-holes that are configured to receive a fastening mechanism to attach the hexagonal drive shaft top end with the mast bottom end,
- wherein the drive shaft bottom end is configured to connect to a power generator, and wherein the drive shaft is configured to rotate axially when the hexagonal mast rotates, which enables the power generator to generate electric power.
A wind turbine comprising:
- a hexagonal mast comprising a mast top end and a mast bottom end;
- a drive shaft comprising a hexagonal drive shaft top end and a drive shaft bottom end, wherein the drive shaft bottom end is cylindrical, wherein the hexagonal drive shaft top end is configured to connect the mast bottom end with the drive shaft,
- wherein the drive shaft bottom end is configured to connect to a power generator, and wherein the drive shaft is configured to rotate axially when the hexagonal mast rotates, which enables the power generator to generate electric power;
- and
- a set of nut packs with interior plates and/or exterior plates configured to attach the hexagonal drive shaft top end with the mast bottom end, wherein a width of each hexagonal mast side is equivalent to a width of each hexagonal drive shaft top end side, and each side of the hexagonal drive shaft top end and the hexagonal mast comprises through-holes that are configured to receive the set of nut packs with interior plates and/or exterior plates.
