Description

Die Erfindung betrifft eine Einrichtung zur Umwandlung von Wasserwellenhubenergie in Rotationsenergie.The invention relates to a device for converting Water wave stroke energy in rotational energy.

Aus der Praxis bzw. der Literatur sind eine ganze Reihe von Einrichtungen bekannt, die zur Umwandlung von Wasserkraft bspw. in elektrische Energie dienen. Voraussetzung für die Umwandlung ist dabei eine Strömung des Wassers wie sie bspw. bei Fallrohren von Stauseen oder auch bei Gezeitenkraftwerken ausgenutzt wird.A whole series of are from practice or the literature Institutions known for the conversion of hydropower, for example serve electrical energy. The prerequisite for the conversion is a flow of water such as that of downpipes from Reservoirs or also used in tidal power plants.

Aus der Literatur gibt es darüber hinaus auch Hinweise auf Anlagen, die den Wellenhub ausnutzen. So ist bspw. in der WO 86/04 391 eine Wellenenergieanlage beschrieben, bei der durch den Wellenhub Wasser in ein Gehäuse einströmen kann, dort dann - bei fallendem Wasser - ein Wasserrad antreibend wieder ausströmt. Hierbei wird allerdings nicht die Hubbewegung im eigentlichen Sinne ausgenutzt, sondern nur die "Fallhöhe" des Wassers.There are also references to from literature Systems that take advantage of the wave stroke. For example, in WO 86/04 391 describes a wave energy system in which the Wave stroke water can flow into a housing, there - at falling water - driving a water wheel flows out again. However, this does not actually mean the lifting movement Exploited senses, but only the "drop height" of the water.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zu schaffen, die den Wellenhub bspw. des Meeres zur Erzeugung einer Rotationsenergie ausnutzt, wobei diese dann in eine elektrische Energie umgewandelt werden kann.The invention has for its object a device create the wave stroke, for example, the sea to generate a Utilizes rotational energy, which is then converted into an electrical Energy can be converted.

Gelöst wird diese Aufgabe erfindungsgemäß mit den Merkmalen im Kennzeichen des Anspruchs 1.This object is achieved according to the invention with the features in Characteristic of claim 1.

Vorzugsweise Ausbildungen ergeben sich aus den Unteransprüchen.Preferred training results from the subclaims.

Kerngedanke der Erfindung ist die Ausbildung der Einrichtung als doppelwandige Trommel, wobei durch eine entsprechende Klappenanordnung innerhalb der Trommel einzelne Kammern geschaffen werden, die durch das steigende Wasser der Welle bzw. durch das fallende Wasser der Welle gefüllt werden und dabei die Trommel selbst in Drehung versetzen. Diese Rotationsenergie kann dann z.B. für die Stromerzeugung ausgenutzt werden. The core idea of the invention is the formation of the device as double-walled drum, with a corresponding Flap arrangement within the drum created individual chambers be caused by the rising water of the wave or by the falling water filled the shaft while doing the drum turn yourself. This rotational energy can then e.g. be used for power generation.  

Denkbare Anwendungszwecke sind bspw. der Einsatz einer derartigen Einrichtung im Bereich von Bohrinseln, um dort die Wellenhubenergie zur Erzeugung von Antriebsenergie für Maschinen, also elektrischen Strom zu benutzen. Durch die entsprechende Vervielfachung der Trommeln auf einer gemeinsamen Welle, können größere Anlagen zusammengestellt werden, die damit dann eine erhöhte Ausnutzung der Wellenhubenergie gewährleisten.Possible uses are, for example, the use of a such facility in the field of oil rigs to there the wave stroke energy for the generation of Driving energy for machines, i.e. electrical current to use. By multiplying the Drums on a common shaft can be larger Plants are put together, which is then a Ensure increased utilization of the shaft stroke energy.

Die Erfindung soll nachfolgend anhand der Zeichnungen erläutert werden. Dabei zeigt:The invention will now be described with reference to the drawings are explained. It shows:

Fig. 1 und 2 jeweils schematisch die Ausbildung der Trommeln bei steigendem (Fig. 1) und fallendem (Fig. 2) Wasser und Fig. 1 and 2 are respectively a schematic configuration of the drums with increasing (FIG. 1) and falling (FIG. 2) of water and

Fig. 3 eine vergrößerte Einheit der Dichtklappenanordnung. Fig. 3 is an enlarged unit of the sealing flap arrangement.

Auf einer gemeinsamen Welle 4 sind nebeneinander mehrere Trommeln 1 angeordnet. Diese Trommeln bestehen jeweils aus einer Trommelinnenwand 3 und einer Trommelaußenwand 2 und den in den Zeichnungen nicht dargestellten Stirnwänden. In der Trommelaußenwand 2 jeder Trommel befinden sich Längsschlitze 15. Zwischen der Trommelinnenwand und der Trommelaußenwand sind Doppeldichtklappen 5, 8 vorgesehen. Dabei ist die Dichtklappe 5 im Bereich der Trommelinnenwand 3 angelenkt, und zwar an einer Schwenkachse 6. Entsprechend ist die Dichtklappe 8 an der Trommelaußenwand 2 angelenkt, wobei hier die Schwenkachse mit 12 bezeichnet ist.Several drums 1 are arranged side by side on a common shaft 4 . These drums each consist of a drum inner wall 3 and a drum outer wall 2 and the end walls, not shown in the drawings. There are longitudinal slots 15 in the outer drum wall 2 of each drum. Double sealing flaps 5 , 8 are provided between the inner drum wall and the outer drum wall. The sealing flap 5 is articulated in the region of the inner drum wall 3 , specifically on a pivot axis 6 . Correspondingly, the sealing flap 8 is articulated on the outer drum wall 2 , the pivot axis being designated 12 here.

Wie sich aus den Figuren ergibt, insbesondere der Fig. 3, sind die Klappen über den Bereich der Anlenkung verlängert, und es sind dort Längsrinnen 7 bzw. 11 vorgesehen, die mit Wasser füllbar sind und die als Gegengewicht dienen. Außerdem weisen die an der Trommelaußenwand 2 angelenkten Klappen 8 noch an der Rückseite Schwimmkörper 10 auf. Wie sich aus der Fig. 1 bzw. der Fig. 3 ergibt, ist die Größe der Klappen so bemessen, daß sie sich im Trommelinneren bei 9 dichtend berühren, wobei diese Dichtkante, wie aus den Zeichnungen ersichtlich, jeweils in den Kammerinnenraum 16 hineinragt in Richtung zu dem dieser Kammer 16 zugeordneten Längsschlitz 15.As can be seen from the figures, in particular from FIG. 3, the flaps are extended over the region of the articulation, and there are longitudinal channels 7 and 11 which can be filled with water and which serve as a counterweight. In addition, the flaps 8 articulated on the outer drum wall 2 also have floating bodies 10 on the rear. As can be seen from FIG. 1 and FIG. 3, the size of the flaps is dimensioned such that they touch sealingly in the interior of the drum at 9 , this sealing edge, as can be seen from the drawings, in each case protrudes into the chamber interior 16 Direction to the longitudinal slot 15 assigned to this chamber 16 .

Betrachtet man nun die Fig. 1, so ist mit 13 angedeutet, daß hier das Wasser bedingt durch einen Wellenhub steigt. Damit füllt sich die in dieser Figur linke Kammer bei geschlossenen Dichtklappen 5, 8 mit Wasser, wobei hier auch die Luft eingeschlossen ist, und je weiter das Wasser mit dem Wellenhub 13 steigt, desto mehr wird diese Seite angehoben, so daß die Trommel sich zu drehen beginnt. Beim Fallen des Wassers, wie dies mit 14 angedeutet ist (Fig. 2), ist auf der rechten Seite die Doppelklappenanordnung geschlossen, und das fallende Wasser nimmt die Trommel somit durch das Gewicht des Wassers wieder mit. Das Zusammenspiel des Steigen des Wassers und des Fallens des Wassers in Verbindung mit den jeweils geöffneten bzw. geschlossenen Klappen führt hier zu einer kontinuierlichen Drehbewegung der Trommel. Diese Drehbewegung kann noch dadurch gleichmäßiger gestaltet werden, daß bei den nebeneinander angeordneten Trommeln die Längsschlitze jeweils versetzt zueinander angeordnet sind, so daß hier das "Ansprechen" der einzelnen Kammern auf die Wellenbewegung zu unterschiedlichen Zeitpunkten stattfindet. Es ist ohne weiteres ersichtlich, daß in diesem Zusammenhang die Schwimmkörper 10 je nach Stand des Wassers für ein Schließen der Klappen sorgen und darüber hinaus die Rinnen 7 bzw. 11 bewirken, daß vor den Klappen befindliches Wasser entweder die Klappen gegeneinander drückt oder als Gegengewicht dienen, so daß noch ein Öffnen erfolgt.Looking now at Fig. 1, it is indicated at 13 that here the water rises due to a wave stroke. The chamber on the left in this figure thus fills with water when the sealing flaps 5 , 8 are closed, the air also being enclosed here, and the further the water rises with the wave stroke 13 , the more this side is raised so that the drum closes starts turning. When the water falls, as indicated at 14 ( FIG. 2), the double flap arrangement is closed on the right-hand side, and the falling water takes the drum with it again due to the weight of the water. The interaction of the rising of the water and the falling of the water in connection with the respectively opened or closed flaps leads here to a continuous rotary movement of the drum. This rotary movement can be made even more uniform in that the longitudinal slots in the drums arranged next to one another are each offset from one another, so that here the "response" of the individual chambers to the shaft movement takes place at different times. It is readily apparent that, in this connection, the floating bodies 10 ensure that the flaps are closed, depending on the level of the water, and, moreover, the channels 7 and 11 cause water in front of the flaps to either press the flaps against one another or serve as a counterweight , so that there is still an opening.
