Abstract
A wind turbine blade device includes a rotating unit including a blade module concentrically connected to a rotating shaft thereof and having a plurality of radially curved channels each having inlet and outlet ends. The inlet and outlet ends of the radially curved channels are configured to respectively permit flow of the flow body into and out thereof. An outer tube includes a tube body surrounding the rotating unit, and a plurality of rib plates provided in the tube body. The outlet end of each radially curved channel corresponds to one of the rib plates, and each radially curved channel forms an included angle with a corresponding rib plate such that the flow body flowing out of the outlet end can impact upon the corresponding rib plate.

A fluid turbine blade device comprising:
- a rotating unit including a rotating shaft extending along an axis, and a first blade module concentrically connected to said rotating shaft, said first blade module being configured to be driven by a flow body to rotate said rotating shaft about the axis in a rotating direction, said first blade module having a plurality of angularly spaced-apart radially curved channels extending radially, outwardly and curvedly from a central portion of said first blade module in a direction opposite to the rotating direction, each of said radially curved channels having a first inlet end proximate to the central portion of said first blade module, and a first outlet end distal from the central portion of said first blade module, said first inlet ends of said radially curved channels being configured to permit flow of the flow body into said radially curved channels, said first outlet ends of said radially curved channels being configured to permit flow of the flow body out of said radially curved channels;
- and
- an outer tube including a tube body surrounding said rotating unit, and a plurality of angularly spaced-apart rib plates provided in said tube body;
- wherein said first outlet end of each of said radially curved channels corresponds to one of said rib plates, and each of said radially curved channels forms an included angle with the corresponding one of said rib plates such that the flow body flowing out of said first outlet end of each of said radially curved channels can impact upon the corresponding one of said rib plates.
