Vorrichtung zur Umwandlung der Bewegungsenergie von Meereswellen in elektrische Energie Die Erfindung betrifft eine Vorrichtung zur Umwandlung der Bewegungsenergie von Meereswellen in elektrische Energie.Device for converting the kinetic energy of sea waves into electrical energy The invention relates to a device for converting kinetic energy from ocean waves into electrical energy.
Wegen des steigenden Energiebedarfs und der abnehmenden Reserven an Brennstoffen, sowie wegen der ungelösten Probleme bei der Nutzung von Kernenergie, stellt sich die Aufgabe, die verfügbare Bewegungsenergie von Meereswellen nutzbar zu machen.Because of the increasing energy demand and the decreasing reserves Fuels, as well as because of the unsolved problems with the use of nuclear energy, The task is to use the available kinetic energy of ocean waves close.
Es sind bereits Vorschläge bekannt, nach denen die Auf- und Abwärtsbewegung der Wellen über Zylinder und Ventile zum Ansaugen und Verdichten von Luft genutzt wird, deren gespeicherte Druckenergie dann über eine Turbine und einen Generator in elektrische Energie umgewandelt wird.There are already proposals known, according to which the upward and downward movement of the shafts via cylinders and valves to suck in and compress air whose stored pressure energy is then via a turbine and a generator is converted into electrical energy.
Nachteilig an Anlagen dieser Art ist, daß die Abwärtsbewegung der Welle nicht in gleichem Maße zur Energieumwandlung genutzt wird wie die Aufwärtsbewegung und daß eine Strömungsmaschine zur Energieumwandlung notwendig ist, was beides zu einem ungünstigen Wirkungsgrad des Energieumwandlungsprozesses führt.The disadvantage of systems of this type is that the downward movement of the Wave is not used to the same extent for energy conversion as the upward movement and that a turbo machine is necessary for energy conversion, which is both leads to an unfavorable efficiency of the energy conversion process.
Aufgabe der Erfindung ist es nun, eine direkte Umwandlung der Bewegungsenergie der Meereswellen in elektrische Energie zu ermöglichen, sowie die weiträumig verteilte Energie unter minimalem Aufwand an Material zu großen, den herkömmlichen Kraftwerken entsprechenden Einheiten zusammenzufassen.The object of the invention is now to convert the kinetic energy directly of the ocean waves in electrical energy, as well as the widely distributed Energy with minimal use of material to large, conventional power plants to summarize the corresponding units.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine Vorrichtung zur Umwandlung der Bewegungsenergie der Meereswellen in elektrische Energie, die dadurch gekennzeichnet ist, daß mehrere, vertikal verschiebbar gelagerte Schwimmkörper mit Hilfe von Zahnstangenantrieben mit je zwei, mit einem Freilauf versehenen Zahnrädern die Auf- und Abwärtsbewegung der Schwimmkörper in eine Drehbewegung von Antriebswellen mit gleichbleibendem Drehsinn umwandeln, die ihrerseits über Kegelräder ihre Drehbewegung auf eine über ein Schwungrad und ein Obersetzungsgetriebe mit einem Generator verbundene zentrale Antriebswelle übertragen.According to the invention this object is achieved by a device for Conversion of the kinetic energy of the ocean waves into electrical energy is characterized in that several, vertically displaceably mounted floating bodies with The help of rack and pinion drives with two gear wheels each with a freewheel the up and down movement of the floats into a rotary movement of drive shafts with a constant sense of rotation, which in turn convert their rotary motion via bevel gears on one connected to a generator via a flywheel and a reduction gear transferred to the central drive shaft.
Die von dem Generator, der zweckmäßigerweise als Gleichstromgenerator auszubilden ist, abgegebene Energie kann weiter mit Hilfe eines Gleichstrommotors zu größeren Einheiten zusammengefaßt werden, indem die Energieeinheiten der einzelnen Generatoren in dem Gleichstrommotor über separate, den einzelnen Generatoren zugeordnete Wicklungen, ein gemeinsames Anker- und Polfeld aufbauen. Der Gleichstrommotor, der zweckmäßigerweise als Nebenschlußmotor auszubilden ist, kann dann zum Antrieb eines Drehstromgenerators dienen, der den gebräuchlichen Drehstrom liefert.The one from the generator, expediently as a direct current generator is to be trained, released energy can be further with the help of a DC motor can be combined into larger units by dividing the energy units of each Generators in the DC motor via separate, assigned to the individual generators Windings, build a common armature and pole field. The DC motor that is expediently designed as a shunt motor, can then be used to drive a Serve three-phase generator, which supplies the usual three-phase current.
Bei der erfindungsgemäßen Vorrichtung sind die Schwimmkörper vorzugsweise als zylindrische, geschlossene Behälter auszubilden, deren Zylindermantel über den Boden hinausragt und einen Überstand bildet, in dem unmittelbar unter dem Boden ein oder mehrere Rückschlagventile angeordnet sind. Zentral durch die Schwimmkörper verläuft eine Führungsstange, die unterhalb und oberhalb des Schwimmkörpers in Lagern geführt ist und die an ihrem oberen Ende als Zahnstange, zweckmäßigerweise mit doppelseitiger Verzahnung, ausgebildet ist.In the device according to the invention, the floating bodies are preferred to be designed as a cylindrical, closed container, the cylinder jacket over the Floor protrudes and forms a protrusion in the immediately below the floor one or more check valves are arranged. Centrally through the floats runs a guide rod, which is below and above the float in bearings is performed and at its upper end as a rack, conveniently with double-sided Toothing, is formed.
Erfolgt durch die Wellenbewegung des Wassers eine Auf- und Abwärtsbewegung des Schwimmkörpers, so wird im Verlaufe der Aufwärtsbewegung infolge der Druckkraftübertragung durch die Zahnstange die Eintauchtiefe des Schwimmkörpers vergrößert; im Verlaufe der anschließenden Abwärtsbewegung dagegen wird LeerseiteThe wave movement of the water causes an upward and downward movement of the float, so is in the course of the upward movement due to the pressure force transmission increases the immersion depth of the float by the rack; during the subsequent downward movement is against it Blank page
