Abstract

The power station is hewn out of the massive rock in a rocky coastline. It could alternatively be made from other suitable materials. One or more openings (i) are provided for the sea, above a system of chambers. The chambers include a reservoir (b) fed with sea water from the approaching waves. A turbine (f) follows the reservoir. This is turned by the water flowing through. A return flow collection chamber (c) after the turbine, contains seawater which will be returned to the sea at the appropriate time.

Description

Wellenkraftanlage bestehend aus Kammernsystem, welches in den Fels einer Felsküste gehauen, oder gesprengt wird (oder aus sonstigem geeigneten Material hergestellt wird).Wave power plant consisting of a chamber system carved in the rock of a rocky coast, or blasted (or made from any other suitable material becomes).

Durch das nach oben offene Becken (niedrige Felsküste), oder durch die Einlasskammern (hohe Felsküste) „eingefangene" Wasser wird durch die Kammern geleitet, strömt nach unten, und treibt eine (oder mehrere) Turbine an, welche wiederum einen Stromgenerator antreibt. Das durch die Turbine durchgeleitete Wasser wird in einem Sammelbecken (Rückflusswasserbecken) gesammelt, und zum geeigneten Zeitpunkt, nach Freigabe durch ein oder mehrere (im Wellenrhythmus arbeitende) Ventile zurück ins Meer geleitet.By the upwardly open basin (low rocky coast), or through the inlet chambers (high rocky coast) "trapped" water gets through the chambers passed, flows down, and drives one (or more) turbine, which in turn drives a power generator. That passed through the turbine Water is collected in a reservoir (reflux pool), and at the appropriate time, after approval by one or more (Operating in wave rhythm) valves back into the sea.

Erläuterung der Funktionsweise eines nach oben geschlossenen Kammernsystems (hohe Felsküste) anhand der 1–4.
(Nach oben offenes Kammernsystems – niedrige Felsküste – siehe 5)Explanation of the functioning of an upwardly closed chamber system (high rock coast) on the basis of 1 - 4 ,
(Chamber system open at the top - low rocky coast - see 5 )

1 höchster Wasserstand bei ankommender Welle.
Eine ankommende Welle füllt die Einlasskammern und damit auch ein (oder mehrere) Sammelbecken (Reservoir). Vom Sammelbecken aus wird das Wasser nach unten (oder seitlich) durch eine Turbine geleitet, welche dadurch angetrieben wird. Über die Turbine wird wie bei herkömmlichen Wasserkraftwerken ein Generator zur Erzeugung von elektrischem Strom angetrieben. Das Sammelbecken muss soviel Wasser aus einer entsprechenden Anzahl von Einlasskammern aufnehmen können, um die Turbine kontinuierlich in Bewegung zu halten, bis eine weitere Welle Wassernachschub bringt.
Hinter der Turbine (in Fließrichtung des Wassers gesehen) befindet sich das Rückflusssammelbecken. Hier sammelt sich das Wasser, bis das Ventil (mehrere Ventile) den Weg zurück ins Meer freigibt. Im abgebildeten Stadium verhindert das Ventil das Eindringen von Meerwasser, aus dem „davor liegenden Meer". 1 highest water level with incoming wave.
An incoming wave fills the inlet chambers and thus one (or more) reservoir (reservoir). From the reservoir, the water is directed down (or laterally) through a turbine, which is powered by it. As with conventional hydroelectric power plants, a generator for generating electric power is driven via the turbine. The sump must be able to hold as much water from a corresponding number of inlet chambers as to keep the turbine moving continuously until another wave brings water replenishment.
Behind the turbine (seen in the direction of flow of the water) is the return pool. Here, the water collects, until the valve (several valves) releases the way back into the sea. In the illustrated stage, the valve prevents the ingress of seawater, from the "sea in front".

2 mittlerer Wasserstand (bei zurückziehender Welle):
Der Wasserspiegel in den Einlasskammern und im Sammelbecken sinkt. Im Abflusswasserbecken steigt der Wasserspiegel an. Das Ventil/die Ventile ist/sind nach wie vor geschlossen. 2 mean water level (with retracting wave):
The water level in the inlet chambers and in the reservoir sinks. In the drainage basin, the water level rises. The valve (s) is / are still closed.

3 unterster Wasserstand:
Kein Wasser in den Einlasskammern, der Wasserspiegel im Sammelbecken sinkt weiter. Der Meerwasserspiegel liegt einen Moment so tief, dass das Ventil (die Ventile) „aufmacht". Das Abflusswasserbecken entleert augenblicklich. 3 lowest water level:
No water in the inlet chambers, the water level in the reservoir sinks further. The seawater level is so low for a moment that the valve (s) "open." The drainage basin empties instantly.

4 mittlerer Wasserstand (bei ansteigender Welle):
Der Wasserspiegel im Sammelbecken sinkt weiter. Das durchfließende Wasser treibt weiterhin die Turbine an. Die Ventile des Abflusswasserbeckens sind wieder geschlossen, daher füllt es sich wieder mit durchgeleitetem Wasser. Mit weiterem ansteigen des Meerwasserspiegels setzt sich der Kreislauf wie in 1 fort. 4 mean water level (with rising wave):
The water level in the reservoir continues to drop. The flowing water continues to drive the turbine. The valves of the drainage basin are closed again, so it fills with water again. With further increase of the sea water level, the cycle continues as in 1 continued.
