Turbine unit and assembly

摘要

A turbine unit (11) adapted to be placed in a flowing fluid. The turbine unit (11) comprises a first turbine set (13) and a second turbine set (15) mounted within a passage (21) of a housing (19). The first turbine blade set (13) and a second turbine blade set (15) are set in opposed relation such that in operation a region between the two turbine blade sets (13, 15) has a lower pressure than the fluid pressure at an opening of the passage (21). The turbine unit (11) being used to generate power. The turbine units (FIGS. 8 to 11) can be abutted with each other such that they define a passage and each turbine unit comprises a driving turbine blade set before fluid passes to a pumping turbine blade set.

1. A turbine unit adapted to be placed in a flowing fluid, the turbine unit comprises a driving turbine blade set and a pumping turbine blade set mounted within a passage of a housing such that in use the driving turbine blade set is located upstream from the pumping turbine blade set, the driving turbine blade set and pumping turbine blade set are confined to rotate in the same direction such that when the fluid flow rotates the driving turbine blade set, the pumping turbine blade set rotates simultaneously at the same rotational speed, the driving turbine blade set and the pumping turbine blade set are mounted in opposed relation whereby the pumping turbine blade set is in reverse relation to the driving turbine blade set such that in operation a region between the two turbine blade sets has a lower pressure than the fluid pressure at an opening of the passage.
