Description

Bidirektionales Gezeitenkraftwerk  Bidirectional tidal power plant
Die vorliegende Erfindung betrifft ein bidirektionales Gezeitenkraftwerk. Die bekannten Lösungen für Gezeitenkraftwerke können in zwei grundlegende Gruppen untergliedert werden: a) Kraftwerke mit bidirektional anströmbaren Maschinen The present invention relates to a bidirectional tidal power plant. The known solutions for tidal power plants can be subdivided into two basic groups: a) Power plants with bi-directional machines
b) Kraftwerke mit unidirektional anströmbaren Maschinen b) Power plants with unidirectionally startable machines
Bei der Verwendung von bidirektional anströmbaren Maschinen besteht der Nachteil darin, dass solche Maschinen trotz erheblichem Aufwand für die hydraulische Auslegung in der Regel einen niedrigeren Wirkungsgrad erreichen, als Maschinen, die nur für eine Fließrichtung optimiert werden müssen. When using bidirectionally inflatable machines, the disadvantage is that such machines usually reach a lower efficiency despite considerable effort for the hydraulic design, as machines that need to be optimized only for one flow direction.
Bei der Verwendung von unidirektional anströmbaren Maschinen kann in der einfachsten Ausgestaltung eines solchen Kraftwerks nur eine Halbperiode der Gezeitenströmung zur Energieerzeugung genutzt werden. Um diesen Nachteil zu überwinden und um auch im Fall von b) ein bidirektionales Gezeitenkraftwerk zu realisieren, wurden jedoch wiederum mehrere bekannte Lösungen vorgeschlagen. When using unidirectionally inflatable machines only a half-period of the tidal current can be used to generate energy in the simplest configuration of such a power plant. However, in order to overcome this disadvantage and to realize a bidirectional tidal power plant also in the case of b), several known solutions have again been proposed.
So wird z.B. in der GB 2 436 857 B vorgeschlagen, zusätzliche Dammstrukturen mit entsprechenden Schleusen dazu zu verwenden, dass der Durchfluss durch die unidirektional anströmbaren Maschinen während der vollen Gezeitenperiode stets in einer Richtung erfolgt. Diese Lösung erfordert einen sehr hohen zusätzlichen Bauaufwand mit entsprechenden zusätzlichen Kosten. For example, in GB 2 436 857 B, it is proposed to use additional dam structures with corresponding locks in such a way that the flow through the unidirectionally inflowable machines always takes place in one direction during the full tidal period. This solution requires a very high additional construction costs with corresponding additional costs.
Eine andere Lösung wird in US 4 159 188 vorgeschlagen. Hier umfasst die Kraftwerksanordnung zwei fest in der Dammstruktur installierte Saugrohre, die kollinear in entgegengesetzter Ausrichtung angeordnet sind. Eine unidirektional anströmbare Maschine ist drehbar zwischen diesen Saugrohren angeordnet und wird bei jeder Umkehr der Strömungsrichtung durch Drehen um eine vertikale Achse um 180° passend zur geänderten Strömungsrichtung ausgerichtet. Auch bei dieser Lösung ist der konstruktive Aufwand sehr hoch. Another solution is proposed in US 4,159,188. Here, the power plant assembly comprises two suction tubes fixedly installed in the dam structure and arranged collinearly in opposite orientation. A unidirectional Anströmbare machine is rotatably disposed between these suction pipes and is aligned at each reversal of the flow direction by rotating about a vertical axis by 180 ° to match the changed flow direction. Even with this solution, the design effort is very high.
Die Erfinder haben sich die Aufgabe gestellt, ein bidirektionales Gezeitenkraftwerk mit einer unidirektional anströmbaren Maschine anzugeben, das wesentlich einfacher und damit kostengünstiger aufgebaut ist, als im Stand der Technik bekannt ist. Dabei löst das erfindungsgemäße Kraftwerk auch noch ein weiteres Problem von solchen Gezeitenkraftwerken. Die Maschinen dieser Kraftwerke unterliegen dem maritimen Bewuchs durch Algen, Muscheln und dergleichen und müssen häufig aufwändig gereinigt werden. Durch die erfindungsgemäße Anordnung wird diese Reinigung entscheidend vereinfacht. Erfindungsgemäß wird diese Aufgabe durch ein bidirektionales Gezeitenkraftwerk mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen des erfindungsgemäßen Kraftwerks ergeben sich aus den abhängigen Unteransprüchen. Die erfindungsgemäße Lösung wird nachfolgend anhand von Figuren erläutert. Darin ist im Einzelnen folgendes dargestellt: The inventors have set themselves the task of providing a bidirectional tidal power plant with a unidirectional inflatable machine, which is much simpler and therefore more cost-effective, as is known in the art. The power plant according to the invention also solves another problem of such tidal power plants. The machines of these power plants are subject to maritime vegetation by algae, shells and the like and often have to be laboriously cleaned. The inventive arrangement, this cleaning is significantly simplified. According to the invention this object is achieved by a bidirectional tidal power plant with the features of independent claim 1. Further advantageous embodiments of the power plant according to the invention will become apparent from the dependent claims. The solution according to the invention is explained below with reference to figures. The following is shown in detail:

Ausführungsform. Figur 1 zeigt in Draufsicht eine Turbinen-Generatoren-Einheit zur Verwendung in einem erfindungsgemäßen Gezeitenkraftwerk, welche mit 1 bezeichnet ist. Die Turbinen-Generatoren-Einheit 1 ist in eine tafelartige Haltestruktur integriert, welche auf beiden Seiten Führungen 10 aufweist. Der Pfeil deutet die vorgesehene Richtung an, in der Wasser durch die Einheit strömen kann. Embodiment. FIG. 1 shows a plan view of a turbine-generator unit for use in a tidal power plant according to the invention, which is designated by 1. The turbine-generator unit 1 is integrated into a panel-like support structure, which has guides 10 on both sides. The arrow indicates the intended direction in which water can flow through the unit.
Figur 2 zeigt in Draufsicht eine Turbinen-Generator-Einheit 1, bei der die tafelartige Haltestruktur breiter ausgeführt ist als in Figur 1. Die Turbinen- Generator-Einheit befindet sich am einen Ende der tafelartigen Haltestruktur. Die Seite der tafelartigen Haltestruktur, die sich in Richtung des anderen Endes erstreckt, bildet eine Tafel 25, die als Teil eines Verschlussorgans fungiert (vgl. Figur 4). Der Pfeil deutet die vorgesehene Richtung an, in der Wasser durch die Einheit strömen kann. Figure 2 shows in plan view a turbine-generator unit 1, in which the sheet-like support structure is made wider than in Figure 1. The turbine-generator unit is located at one end of the panel-like support structure. The side of the panel-like support structure that extends toward the other end forms a panel 25 which functions as part of a closure member (see Figure 4). The arrow indicates the intended direction in which water can flow through the unit.
Figur 3 zeigt in Draufsicht ein erfindungsgemäßes Gezeitenkraftwerk mit zwei Wasserwegen 21 und 22. Die Pfeile deuten die Strömungsrichtungen an, die für die beiden Wasserwege vorgesehen sind. In jedem Wasserweg ist ein Saugrohr 23 und 24 gemäß der vorgesehen Strömungsrichtung angeordnet. Weiter sind in jedem Wasserweg Aufnahmen 20 vorgesehen, mittels denen eine Turbinen- Generator-Einheit 1 über die Führungen 10 in jeweils einen der Wasserwege integriert werden kann. Die Einführung der Einheit 1 erfolgt dabei in vertikaler Richtung z.B. mit Hilfe eines Krans oder irgendeiner anderen geeigneten Hebevorrichtung. Die Aufnahmen 20 sind so angeordnet, dass die Einheit 1 der jeweiligen vorgesehen Strömungsrichtung entsprechend orientiert eingebaut werden kann. Das bedeutet, dass die Einheit 1 direkt vor der jeweiligen Saugrohrmündung angeordnet ist. In Figur 3 ist die Einheit 1 in den Wasserweg 22 integriert dargestellt. Weiter umfasst das erfindungsgemäße Gezeitenkraftwerk ein Verschlussorgan, das jeweils den Wasserweg verschließen kann, in dem sich die Einheit 1 nicht befindet. In Figur 3 geschieht das durch die Tafeln 251 und 252, wobei die Tafel 251 durchgezogen dargestellt ist, da sie sich in Verschlussposition befindet. Tafel 252 ist gestrichelt dargestellt, das sie sich in geöffneter Position befindet (d.h. nach oben aus dem Wasserweg herausgezogen). In der dargestellten Anordnung kann daher Wasser nur durch den Wasserweg 22 fließen, Wasserweg 21 ist für die Durchströmung gesperrt. Wenn sich in dem in Figur 3 dargestellten erfindungsgemäßen Gezeitenkraftwerk die Strömungsrichtung ändert, so werden folgende Schritte in der genannten Reihenfolge ausgeführt: Unterbrechung des Wasserstromes (z.B. durch Absenken der Tafel 252 oder eines weiteren Verschlussorgans, das den Wasserstrom durch das Kraftwerk generell unterbinden (nicht dargestellt)); Entfernen der Einheit 1 aus Wasserweg 22 in vertikaler Richtung (d.h. nach oben); Schwenken der Einheit 1 und Einführung in Wasserweg 21 mittels Aufnahmen 20 und Führungen 10; Verschließen des Wasserweges 22 mittels Tafel 252 (falls nicht bereits erfolgt); Öffnen des Wasserweges 21 mittels Tafel 251. Bei einem Strömungsrichtungswechsel in anderer Richtung werden folgende Schritte durchgeführt: Unterbrechung des Wasserstromes (z.B. durch Absenken der Tafel 251 oder eines weiteren Verschlussorgans, das den Wasserstrom durch das Kraftwerk generell unterbinden kann (nicht dargestellt)); Entfernen der Einheit 1 aus Wasserweg 21 in vertikaler Richtung (d.h. nach oben); Schwenken der Einheit 1 und Einführung in Wasserweg 22 mittels Aufnahmen 20 und Führungen 10; Verschließen des Wasserweges 21 mittels Tafel 251 (falls nicht bereits erfolgt); Öffnen des Wasserweges 22 mittels Tafel 252. FIG. 3 shows a plan view of a tidal power plant according to the invention with two water passages 21 and 22. The arrows indicate the flow directions which are provided for the two water passages. In each waterway, a suction pipe 23 and 24 is arranged according to the intended flow direction. Further, receptacles 20 are provided in each waterway, by means of which a turbine-generator unit 1 can be integrated via the guides 10 in each case one of the waterways. The introduction of the unit 1 takes place in the vertical direction, for example by means of a crane or any other suitable lifting device. The receptacles 20 are arranged so that the unit 1 of the respective provided flow direction can be installed according oriented. This means that the unit 1 is arranged directly in front of the respective Saugrohrmündung. In Figure 3, the unit 1 is in the waterway 22 shown integrated. Furthermore, the tidal power plant according to the invention comprises a closure member, which can close each of the waterway in which the unit 1 is not located. In Figure 3 this is done by the panels 251 and 252, the panel 251 is shown in solid, because it is in the closed position. Panel 252 is shown in phantom in that it is in the open position (ie, pulled upwards out of the waterway). In the illustrated arrangement, therefore, water can only flow through the waterway 22, waterway 21 is blocked for the flow. If the flow direction changes in the tidal power plant according to the invention shown in FIG. 3, the following steps are carried out in the stated order: interruption of the water flow (eg by lowering the panel 252 or another closure member which generally prevents the flow of water through the power plant (not shown) )); Removing the unit 1 from waterway 22 in the vertical direction (ie upwards); Pivoting the unit 1 and introduction to waterway 21 by means of receptacles 20 and guides 10; Closing the waterway 22 by means of panel 252 (if not already done); Opening the water path 21 by means of panel 251. In a flow direction change in the other direction, the following steps are performed: interruption of the water flow (eg by lowering the panel 251 or another closure member that can generally prevent the flow of water through the power plant (not shown)); Removing the unit 1 from waterway 21 in the vertical direction (ie upwards); Pivoting the unit 1 and introduction to waterway 22 by means of receptacles 20 and guides 10; Closing the waterway 21 by means of panel 251 (if not already done); Opening the waterway 22 by means of panel 252.
Figur 4 zeigt in Draufsicht ein erfindungsgemäßes Gezeitenkraftwerk mit zwei Wasserwegen 21 und 22. Im Gegensatz zu Figur 3 grenzen die Wasserwege 21 und 22 direkt aneinander an, d.h. sie heben eine gemeinsame in der Mitte liegende Wand. Die Pfeile deuten die Strömungsrichtungen an, die für die beiden Wasserwege vorgesehen sind. In jedem Wasserweg ist ein Saug roh r 23 und 24 gemäß der vorgesehen Strömungsrichtung angeordnet. Weiter sind in jedem Wasserweg Aufnahmen 20 vorgesehen, mittels denen eine Turbinen-Generator- Einheit 1 gemäß Figur 2 über die Führungen 10 integriert werden kann. Dabei befindet sich die eigentliche Turbinen-Generator-Einheit 1 jeweils in einem Wasserweg, während der andere Wasserweg durch die in die Einheit 1 integrierte Tafel 25 verschlossen wird. Die Einführung der Einheit 1 erfolgt dabei in vertikaler Richtung z.B. mit Hilfe eines Krans oder irgendeiner anderen geeigneten Hebevorrichtung. Die Aufnahmen 20 sind so angeordnet, dass die Einheit 1 der jeweiligen vorgesehen Strömungsrichtung entsprechend orientiert eingebaut werden kann. Das bedeutet, dass die Einheit 1 direkt vor der jeweiligen Saugrohrmündung angeordnet ist. In Figur 4 ist die Einheit 1 in den Wasserweg 22 integriert dargestellt, wobei der Wasserweg 21 durch die Tafel 25 verschlossen wird. In der dargestellten Anordnung kann daher Wasser nur durch den Wasserweg 22 fließen, Wasserweg 21 ist für die Durchströmung gesperrt. FIG. 4 shows a plan view of a tidal power plant according to the invention with two waterways 21 and 22. In contrast to FIG. 3, the waterways 21 adjoin and 22 directly to each other, ie they raise a common central wall. The arrows indicate the flow directions that are provided for the two waterways. In each waterway is a suction raw r 23 and 24 arranged according to the intended flow direction. Further, receptacles 20 are provided in each waterway, by means of which a turbine-generator unit 1 according to Figure 2 can be integrated via the guides 10. In this case, the actual turbine-generator unit 1 is in each case in a waterway, while the other waterway is closed by the integrated unit 1 in the panel 25. The introduction of the unit 1 takes place in the vertical direction, for example by means of a crane or any other suitable lifting device. The receptacles 20 are arranged so that the unit 1 of the respective provided flow direction can be installed according oriented. This means that the unit 1 is arranged directly in front of the respective Saugrohrmündung. In Figure 4, the unit 1 is shown integrated into the waterway 22, wherein the waterway 21 is closed by the panel 25. In the illustrated arrangement, therefore, water can only flow through the waterway 22, waterway 21 is blocked for the flow.
Wenn sich in dem in Figur 4 dargestellten erfindungsgemäßen Gezeitenkraftwerk die Strömungsrichtung ändert, so werden folgende Schritte in der genannten Reihenfolge ausgeführt: Unterbrechung des Wasserstromes (z.B. durch Schließen eines weiteren Verschlussorgans, das den Wasserstrom durch das Kraftwerk generell unterbinden kann (nicht dargestellt)); Entfernen der Einheit 1 aus Wasserweg 22 in vertikaler Richtung (d.h. nach oben; dabei wird auch Tafel 25 aus dem Wasserweg 21 entfernt); Drehen der Einheit 1 um 180° (um eine geeignete vertikale Achse - ist in Figur 4 durch einen kleinen Kreis angedeutet) und Einführung in Wasserweg 21 mittels Aufnahmen 20 und Führungen 10 (die Einheit 1 befindet sich nun vor dem Saugrohr 23; dabei wird auch der Wasserweg 22 durch Tafel 25 verschlossen); Öffnen des Wasserstromes (durch Öffnen des weiteren Verschlussorgans). Bei einem Strömungsrichtungswechsel in anderer Richtung werden folgende Schritte durchgeführt: Unterbrechung des Wasserstromes (z.B. durch Schließen eines weiteren Verschlussorgans, das den Wasserstrom durch das Kraftwerk generell unterbinden kann (nicht dargestellt)); Entfernen der Einheit 1 aus Wasserweg 21 in vertikaler Richtung (d.h. nach oben; dabei wird auch Tafel 25 aus dem Wasserweg 22 entfernt); Drehen der Einheit 1 um 180° (um eine geeignete vertikale Achse - ist in Figur 4 durch einen kleinen Kreis angedeutet) und Einführung in Wasserweg 22 mittels Aufnahmen 20 und Führungen 10 (die Einheit 1 befindet sich nun vor dem Saugrohr 24; dabei wird auch der Wasserweg 21 durch Tafel 25 verschlossen); Öffnen des Wasserstromes (durch Öffnen des weiteren Verschlussorgana). If the direction of flow changes in the tidal power plant according to the invention as shown in FIG. 4, the following steps are carried out in the stated order: interruption of the water flow (eg closing of another closure element which can generally prevent the flow of water through the power plant (not shown)); Removing the unit 1 from the waterway 22 in the vertical direction (ie, upwards, thereby also removing panel 25 from the waterway 21); Rotating the unit 1 by 180 ° (about a suitable vertical axis - is indicated by a small circle in Figure 4) and introduction to waterway 21 by means of receptacles 20 and guides 10 (the unit 1 is now in front of the suction tube 23; the waterway 22 closed by panel 25); Opening the water flow (by opening the further closure member). In the case of a flow direction change in the other direction, the following steps are carried out: interruption of the water flow (eg by closing a further closure member which can generally prevent the flow of water through the power plant (not shown)); Removing the unit 1 from the waterway 21 in the vertical direction (ie upwards, thereby also removing panel 25 from the waterway 22); Turning the unit 1 180 ° (about a suitable vertical axis - is indicated by a small circle in Figure 4) and introduction to waterway 22 by means of receptacles 20 and guides 10 (the unit 1 is now in front of the suction tube 24; the waterway 21 closed by panel 25); Opening the water flow (by opening the other closing organ).
Es ist anzumerken, dass ein erfindungsgemäßes Gezeitenkraftwerk auch mehrere der in Figur 3 und Figur 4 dargestellten Anordnungen umfassen kann. Auch in Kombination dieser Ausführungsformen. It should be noted that a tidal power plant according to the invention can also comprise several of the arrangements shown in FIG. 3 and FIG. Also in combination of these embodiments.
Die erfindungsgemäßen Anordnungen sind damit wesentlich einfacher aufgebaut, als die im Stand der Technik beschriebenen. Außerdem kann die Generator- Turbinen-Einheit sehr leicht gereinigt werden, da die erfindungsgemäße Anordnung ohnehin die Möglichkeit vorsieht, die Generator-Turbinen-Einheit in vertikaler Richtung aus den Wasserwegen zu entfernen. Damit besteht eine optimale Zugänglichkeit zum Zweck der Reinigung. The arrangements according to the invention are thus constructed much simpler than those described in the prior art.
