Definitions

  • the present invention relates to improvements in the vertical axis blade structure of a wind power generator.
  • the blades of a wind turbine are usually divided into two types, one is to set the blades on the axis parallel to the ground, and the other is to set the blades on the axis perpendicular to the ground, called the vertical axis blades.
  • the vertical shaft blade power generation device can eliminate the cumbersome rotating platform; therefore, the structure is relatively simple, but the current blade structure is not reasonable, affecting the wind utilization efficiency, and affecting the power generation.
  • the present invention has been made in view of the above problems, and provides a vertical shaft blade which can improve the utilization efficiency of wind.
  • the present invention includes a vertical central axis, the structural points of which are evenly distributed with an odd number of blades outside the vertical central axis, and one side of the cross section of the blade is a streamlined curved windward surface, opposite to the windward surface. The other side is a concave leeward side.
  • the vertical central axis of the present invention is evenly distributed with an odd number of blades, one side of the cross section of the blade is a streamlined curved windward surface, and the other side of the windward side is a concave leeward surface, which can be oriented regardless of the wind direction.
  • the blades of the invention are fully utilized, and therefore, the power generation of the wind turbine can be improved.
  • Figure 1 is a schematic view of the structure of the present invention
  • Fig. 2 is a cross-sectional view taken along line A-A of Fig. 1;
  • the present invention comprises a vertical central axis 1 , an even number of blades 2 being evenly distributed outside the vertical central axis 1 , one side of the section of the blade 2 being a streamlined curved windward face 5 and the other side of the opposite windward face 5 being Concave leeward
  • a cylinder 3 may be disposed between the windward surface 5 and the leeward surface 4 of the blade 2, and the cylinder 3 is connected to the windward surface 5 and the leeward surface 4, respectively.
