Abstract:
Die Erfindung betrifft eine Turbine, insbesondere zur Energiegewinnung in strömender Luft oder in Fliessgewässern, die an unterschiedliche Einsatzbedingungen in einfacher Weise anpassungsfähig ist und die einen vergleichsweise hohen Wirkungsgrad ermöglicht. Dies ist dadurch gelöst, die Turbine in ihrer Grundform zylinderförmig ist und mit Schaufeln (4) versehen ist, die parallel zu einer Achse (2) der Turbine angeordnet sind, wobei die Schaufeln (4) schwenkbar in Gelenken (6) am Aussenumfang mindestens eines Turbinenrades (3) angeordnet sind. Die Schaufeln (4) sind im Wesentlichen L-förmig, wobei ein langer Schenkel (41) der Schaufel (4) bevorzugt entsprechend des Radius des Turbinenmantels gebogen ist und ein kurzer Schenkel (42) innerhalb der Mantellinie der Turbine gelegen ist.
Abstract:
A device to produce electricity using the flowing water or the lashing sea waves. It is a novel method of underwater turbine comprising of a central axis 2 with which the popping up drag door pans 3 are attached laterally in multiples at equal distance, a set of gears which transfer the force from the central axis 2 to the generator 6, a floating system that helps the whole instrument to float in the water column and a metal stand 1 which holds all the components. The popping up drag door/s 4 of the popping up drag door pan 3 is open able only one side. The popping up drag door/s of two opposite popping up drag door pans 3 are open able towards the opposite directions. While the water flowing or lashing over the turbine, the popping up drag door/s 4 of one popping up drag door pan 3 is forcefully opened by the water force and the water passes to the other side through the gaps of the opened door/s. Simultaneously, the popping up drag door/s 4 of the opposite popping up drag door pan 3 are forcefully closed by the water force, the popping up drag door pan 3 is pushed back and in turn the central axis 2 is rotated.

Abstract:
The invention is a device for transforming wave motion and/or the motion of the flow of a watercourse into a motion suited to set an electricity generator rotating, comprising at least one module (M) with rotation axis (7), planes (1 ) mounted orthogonally and rigidly on said axis (7), and wherein a plurality of blades (3) are furthermore hinged to at least one surface of each one of said planes (1), wherein said blades (3) are directly hinged to the surface of the corresponding circular plane (1) and rotate due to gravity and to the thrusting force of the water, with respect to the corresponding plane (1), between a position of minimum thrust, in which the thrusting surface is substantially parallel to the plane (1) and close or adherent to the corresponding plane (1), and a position of maximum thrust, in which the thrusting surface is substantially orthogonal to the plane (1).
Abstract:
A turbine (10) for the production of electric energy associated with a system for the production of electric energy (12), consisting at least of one station (11) operating in a flow of fluid streamlines, such as water or air, consists of at least a rotating unit (27) and is provided with equidistant blades. The blades are horizontally pivoting around a pivoting axis substantially parallel to the axis of said rotating unit (27) and have a position of maximum radial opening and a position of minimum radial opening. The axis of rotation of said rotating unit (27) is placed substantially vertical and orthogonal with respect to the flow of fluid.
Abstract:
An apparatus for extracting fluid motion energy, comprising one or more blades. Each blade comprising one or more vanes. Each vane having an exposed area. The exposed area when impinged by fluid motion, that is generally in the direction of the movement of a blade, is larger than the exposed area when not impinged by fluid motion. And the exposed area when impinged by fluid motion, that is generally opposing the direction of the movement of the blade, is smaller than the exposed area when not impinged by fluid motion.
