Description

For the production of electricity from water, traditionally various turbine types are used such as Pelton, Kaplan, Francis, etc. They have different characteristics and efficiency ratio depending on the water quantity, water head, the possibility of changing the angle of the propellers, etc. In all known models, water losses are observed, which prevents reaching an optimum efficiency ratio. Additionally these turbines in terms of construction and technical design are not capable of handling small-volume flowing water such as small urban channels, brooklets, small rivers.
The current development proposes a new technical solution by a unique water-piston technical device. It consists of special open-and-close pistons attached to a closed chain, a belt, metal cords, a cylinder tube and metal body.

The system comprises at least one of four pistons mounted equal distance from each other on the belt 11, which communicates with a sprocket 16. Pistons are placed in a specially designed cylinder 18, the upper end of which is shaped as a funnel 22 so that it seamlessly to do pistons and infused water. Belt 11 is mounted on the upper bracket 38 and lower bracket 24; on these supports are mounted rollers 25 respectively, the lower bracket 24 and roller 39 of the upper bracket 38. The lower bracket 24 is mounted on one of the inner walls of pipe 19. The upper bracket 38 is hinged to the axis 29 of the funnel 22 and is hinged at the axes 28 and 40 with buckle 27. Piston 1 comprises upper 15 and lower part 8. The upper part 15 of the piston 1 is fitted with two removable lid 2 and 41 of the inner edges of which are shaped “U”-shaped cuts 3 and 44. On both sides of the piston are shaped cuts of different sizes, respectively, cut 14 of the top 15, which is wider than the cut 13 of the bottom 8 of the piston 1.

Solution

The current development enables the handling of small-volume water flows to produce electricity. The known turbine types are not capable of working with or have low efficiency ratio when operating with small water quantities and low head. The new technical solution is expected to achieve a maximum efficiency ratio because it does not allow water wastes and the water energy is transformed in electricity to the maximum extent.
