Converter for transforming underwater flows into electrical energy, has foldable blades arranged on toothed belt arranged on two horizontal shafts

摘要

The converter has propeller blades attached to a horizontal shaft and fixed to a frame. Alternatively, a type of tail-fin blade is moveable alternately upwards and downwards. A toothed belt (3) is arranged on at least two horizontal shafts (6,7) and toothed-belt wheels (4,5). A drive blade (1) that can be folded by 90 degrees is attached to the belt, its front surface aligned against the direction of water flow.
