Abstract:
System has a power generator (3) slidably placed against the horizontal shaft (2) inside the floating impeller (1). The horizontal shaft (2) captures the moment reaction of the power generator (3). Inside the floating impeller (1) there is a mechanism (5) of sliding of the power generator (3), whereby the gear mechanism (4) which transfers the impeller's rotation to the generator's (3) rotor is adjusted for the sliding of the power generator (3) in the direction alongside the axis of rotation. In a preferable arrangement there is a multi-position angular lock (11) between the horizontal shaft (2) and the hinge of the power generator (3); this lock (11) can release the rotational bond between the power generator (3) and horizontal shaft (2); this causes the power generator (3) to descend into lowest position. This process can be simplified by the clutch between pinion (8) and power generator's (3) rotor. The system of balancing can be used to alter the hydrodynamic effectiveness of the floating impeller (1), to stop the impeller (1), to change its rotations or to stabilize it during the movement caused by outside influence.
Abstract:
Impeller (2) is placed in a cage (1) with self-supporting frame; the cage (1) has two side walls and a lower frame construction designed to be placed on the bottom of the water flow. The cage (1) can have at least one anchoring element (4) to anchor the cage (1) to the ground. The cage (1) can have outer shapes and dimension of the standardized cargo container, preferably in the dimension series from 1 Dx to 1AAA. The impeller (2) is floating and its size is smaller than half of the load displacement of its total volume; thanks to this the impeller (2) follows the actual state of the water level. The impeller (2) is rotationally placed on the shaft running through its inside, where the electric power generator is hung. This generator is connected to the rotation of the impeller (2). The impeller is placed on two swing arms (3); the arms (3) are led inside alongside side walls of the cage (1); alternatively, the impeller (2) is stably placed and the upper inlet trough (7) is directed towards it from above.

Abstract:
A water flow turbine arrangement is disclosed which can be used for capturing energy from water flows. The arrangement comprises: a base member (212): a generally open support structure (210) mounted to the base and upstanding therefrom, the support structure including plural legs (216) joined by a cross brace at or adjacent their upper ends; an electrical generator (230) mounted to the base; and shaft mounted turbine blades (220) mounted for rotation generally within the space occupied by the legs about a turbine axis. The turbine shaft (222) is supported at its upper end by the cross brace and is coupled to the generator at its lower end by a magnetic torque transmitting coupling, allowing complete fluid sealing of the generator's housing.
Abstract:
Es ist die Aufgabe der vorliegenden Erfindung, einen Rotor bereitzustellen, der einfach, effizient und zur Nutzung in kleinen Wind- oder Wasserkraftanlagen geeignet ist. Diese Aufgabe wird durch einen Rotor gelöst, der umfasst: - eine Rotationsachse; - einen ersten gekrümmten Hauptflügel mit einer ersten konkaven Vorderfläche; und - einen, insbesondere zum ersten Hauptflügel baugleichen, zweiten Hauptflügel mit einer zweiten konkaven Vorderfläche, der bezüglich der Rotationsachse achsensymmetrisch zum ersten Hauptflügel gehaltert und ausgerichtet ist, gekennzeichnet durch: - einen ersten Vorflügel auf der der konkaven Fläche des ersten Hauptflügels zugewandten Seite; und - einen, insbesondere zum ersten Vorflügel baugleichen, zweiten Vorflügel auf der der konkaven Fläche des zweiten Hauptflügels zugewandten Seite.
Abstract:
An electrical generation system. A floating vessel is anchored in flowing water. Inlets in the hull of the vessel capture flowing water and direct the water to one or more turbines. The system is designed so that all flows are two-dimensional to the extent possible. The latter feature greatly simplifies both design and construction.
Abstract:
A run-of-the-river or ocean current turbine may comprise a hatch 1612 and a slanted block 1605 having protector ribs 1630 for directing water flow to a waterwheel 1608, The hatch may be controlled by a plurality of Transgear™ gear assemblies 2210, 2220, 2230, 2240 for varying the amount of water flow to the waterwheel from extreme drought to flood conditions so that the waterwheel may turn at rated speeds and within a predetermined range. The Transgear gear assemblies may comprise an accumulator 3010 for accumulating a rough and a fine tuned waterwheel speed. The Transgear assemblies may comprise embodiments of power take-off switches for, for example, bi-directional or clockwise and counterclockwise waterwheel shaft rotation, The turbine may be aligned for top-feed, side-feed or bottom feed of water and may comprise a tail wing or first and second turbines facing in opposite directions to capture high and low tidal flow.
