Abstract
A fluid turbine blade device includes a vertical axis support base having a fulcrum-forming depression which acts as a first part, and a rotary assembly including a hub lid and a sleeve member rotatably surrounding the vertical axis support base. The hub lid has a projection acting as a second part and rotatably connected to the first part. The fluid turbine blade device further includes a plurality of blade modules mounted to the sleeve member and acted upon by fluid to drive the sleeve member to rotate, and a collision avoidance unit including a plurality of magnets disposed on the outside of the vertical axis support base and the inside of the rotary assembly to produce repulsive force.
Claims2
A fluid turbine blade device, comprising:
- a vertical axis support base extending along a vertical axis, and including a top section that has a first part located at the vertical axis;
- a rotary assembly coaxially mounted to said vertical axis support base, and including a hub lid that is rotatably and coaxially assembled with said vertical axis support base, and a sleeve member that extends downward from said hub lid and that is radially spaced from said vertical axis support base, said hub lid having a second part that is coaxially connected to said first part;
- and that is rotatable about the vertical axis relative to said first part;
- a collision avoidance unit arranged between said vertical axis support base and said rotary assembly, and including a plurality of first magnets that are disposed on the outside of said vertical axis support base, and a plurality of second magnets that are disposed on the inside of said rotary assembly and that correspond respectively in position to said first magnets for producing a repulsive force between said plurality of first magnets and said plurality of second magnets;
- and
- a plurality of blade modules, each blade module including a blade that is spaced from said rotary assembly, and a link rod assembly that is coupled between said rotary assembly and said blade, said blade being acted upon by fluid to drive said sleeve member to rotate
- wherein said top section includes a cavity on an upper end thereof for holding lubricant, said cavity having a bottom surface that defines said first part in communication with said cavity;
- wherein said hub lid includes a lid body positioned above and spaced apart from said vertical axis support base, and a protrusion extending downward from said lid body into said cavity and defining said second part on a lower end thereof for rotatably connected to said first part;
- wherein said first part is a fulcrum-forming depression on said bottom surface of said cavity, and said second part is a projection downward extending from said lower end of said protrusion;
- and
- wherein said fulcrum-forming depression and said projection are conical.
