Green energy by screw technology joint device for use on turns of e.g. hydrodynamic screw to produce hydroelectric energy, has flexible joint fixed on turns of Archimedes screw to reduce gap between turn and trough to distance

摘要

The device has a flexible joint (4) fixed on turns of Archimedes screw (1) by bolting, riveting, joining and pinching, to reduce a gap between the turns of the screw and trough to a distance of tenth of millimeter. The flexible joint is made of flexible and hydrophobic materials e.g. Teflon (RTM: PTFE) or rubber. Dimensions e.g. length, thickness and angle, of the flexible joint permit dimensional overflow on the trough.
