Abstract

Die Erfindung zeigt ein neuartiges Kraftwerk zur Erzeugung von elektrischem Strom durch die Ausnutzung der kinetischen Energie von Meereswellen. Im Gegensatz zu bekannten: Propeller/ Wellensegel/ hydraulischen, oder anderen Systemen, nutzt eine geneigt liegende Archimedische Schraube die Wellenenergie, der an den Strand auflaufenden Meereswellen effizient und simpel aus. Durch die Schubkraft der Meereswellen in Ufernähe, die das Wasser auf die Schneckengänge ausübt, gerät die Archimedische Schraube in eine Rotation, wodurch ein Generator angetrieben wird, welcher elektrischen Strom erzeugt. Der Generator-Rotor ist mit der Archimedischen Schraube gekoppelt. Der Generator-Stator ist mit einer Halterung am Meeresboden verbunden. Durch deren Kugelgelenk sind seitliche.-und Höhenbewegungen möglich, ohne das der Stator sich dreht. Das gleiche System: Kugelgelenk, wird beim Abstandshalter angewandt. Entsprechende Dichtungen, eventuelle Getriebe und Flansche ermöglichen die Zerlegung in einzelne wasserdichte Bauteile. Ein Unterwasserkabel leitet den elektrischen Strom zum Strand. (siehe Zeichnung)Die vorstehende Konstruktion benötigt kein Einlaufbauwerk und kann sich, selbstjustierend, auch seitlichen Wellenbewegungen anpassen. Das Meereswellenkraftwerk ist ungefährlich für Fische, durchlässig für Sedimente und Treibgut.The invention shows a novel power plant for generating electric power by utilizing the kinetic energy of sea waves. Unlike known propellers / wave sails / hydraulic, or other systems, a tilted Archimedean screw uses the wave energy, the sea waves coming to the beach, efficiently and simply. Due to the thrust of the sea waves near the shore, which exerts the water on the flights, the Archimedean screw gets into a rotation, which drives a generator that generates electricity. The generator rotor is coupled to the Archimedean screw. The generator stator is connected to a bracket on the seabed. Through the ball joint lateral. And height movements are possible without the stator rotates. The same system: ball joint, is applied to the spacer. Corresponding seals, possible gears and flanges allow the separation into individual waterproof components. An underwater cable directs the electrical power to the beach.

The marine wave power plant is safe for fish, permeable to sediment and flotsam.

Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft eine neuartige Vorrichtung zur Erzeugung elektrischer Energie mittels eines Meereswellen-Kraftwerkes. Die Besonderheit liegt in einem neuen Einsatzbereich der bekannten Archimedischen Schraube / Wasserkraftschnecke.The present invention relates to a novel device for generating electrical energy by means of a marine wave power plant. The special feature lies in a new field of application of the well-known Archimedean screw / hydrodynamic screw.

Stand der TechnikState of the art

Bekannt sind viele Geräte und Systeme zur Ausnutzung der Meereswellenenergie. Neu ist die Nutzung der Meereswellen- Energie im Meeres- Uferbereich durch eine Archimedische Schraube in geneigter Lage.Many devices and systems for exploiting the ocean wave energy are known. New is the use of sea-wave energy in the sea shore area by an Archimedian screw in an inclined position.

Darstellung der ErfindungPresentation of the invention

Im Gegensatz zu bekannten: Propeller/ Wellensegel/ hydraulischen, oder anderen Systemen, nutzt eine geneigt liegende Archimedische Schraube die kinetische Wellenenergie, der an den Strand auflaufenden Meereswellen effizient und simpel aus. Durch die Schubkraft der Meereswellen in Ufernähe, die das Wasser auf die Schneckengänge ausübt, gerät die Archimedische Schraube in eine Rotation, wodurch ein Generator angetrieben wird, welcher elektrischen Strom erzeugt. Der Generator-Rotor ist mit der Archimedischen Schraube gekoppelt. Der Generator-Stator ist mit einer Halterung am Meeresboden verbunden. Durch deren Kugelgelenk sind seitliche.-und Höhenbewegungen möglich, ohne das der Stator sich dreht. Das gleiche System wird beim Abstandshalter angewandt. Entsprechende Dichtungen, eventuelle Getriebe und Flansche ermöglichen die Zerlegung in einzelne wasserdichte Bauteile. Ein Unterwasserkabel leitet den elektrischen Strom zum Strand.In contrast to known propellers / wave sails / hydraulic or other systems, a tilted Archimedean screw uses the kinetic wave energy, the ocean waves coming to the beach, efficiently and simply. Due to the thrust of the sea waves near the shore, which exerts the water on the flights, the Archimedean screw gets into a rotation, which drives a generator that generates electricity. The generator rotor is coupled to the Archimedean screw. The generator stator is connected to a bracket on the seabed. Through the ball joint lateral. And height movements are possible without the stator rotates. The same system is applied to the spacer. Corresponding seals, possible gears and flanges allow the separation into individual waterproof components. An underwater cable directs the electrical power to the beach.

Andere Systeme nutzen nur einen Teil der kinetischen Wellenenergie aus, da dort meist nur ein Wellenhub ausgenutzt wird, während bei einer Archimedischen Schraube die horizontalen Wellen- Schubkräfte über eine längere Strecke ausgenutzt werden. Die Erfindung ist eine Weiterentwicklung der Gebrauchsmuster-Anmeldung: Aktenzeichen 20 2014 002 933.4/ 4.4.2014, mit dem Ziel die Konstruktion zu vereinfachen und somit die Baukosten wesentlich zu reduzieren. Das gelingt dadurch, dass das Wellenkraftwerk an einem Punkt im Meeresboden verankert wird. Dieser Fixpunkt ist in sich drehbar. Mittels eines Schwimmers wird die Archimedische Schraube in die gewünschte Neigung gebracht. Eine Abstandshalterung hält die Archimedische Schraube zusätzlich in der geneigten Lage und ermöglicht deren, in Grenzen, seitliches Ausweichen. Es erfolgt somit eine Selbstzentrierung in Wellenlaufrichtung. Der fest stehende Stromgenerator- Stator erzeugt, durch die sich drehende Mittelachsen-Rotor der Archimedischen Schraube, Elektrizität.Other systems use only part of the kinetic wave energy, since most of the time only one shaft stroke is used there, while with an Archimedean screw the horizontal wave shear forces are utilized over a longer distance. The invention is a further development of the utility model application: file number 20 2014 002 933.4 / 4.4.2014, with the aim of simplifying the construction and thus significantly reducing the construction costs. This is achieved by anchoring the wave power plant at a point in the seabed. This fixed point is rotatable in itself. By means of a float the Archimedean screw is brought into the desired inclination. A spacer keeps the Archimedes screw in the inclined position and allows them, within limits, sideways evasion. There is thus a self-centering in the direction of shaft travel. The fixed current generator stator generates electricity through the rotating center axis rotor of the Archimedean screw.

Durch die vorstehende Konstruktion benötigt das Wellenkraftwerk kein Einlaufbauwerk und kann sich, selbstjustierend seitlichen Wellenbewegungen anpassen. Das Meereswellenkraftwerk ist ungefährlich für Fische, durchlässig für Sedimente und Treibgut.Due to the above construction, the wave power plant does not need an intake structure and can adapt to self-adjusting lateral shaft movements. The marine wave power plant is safe for fish, permeable to sediment and flotsam.
