Abstract

The device comprises a container which rests on the seabed and which has at least one movable wall section, which oscillates about a fixed point, independent of the tides. The container is filled with air and is coupled to a second container with flexible walls. This is connected to a third container, which is identical to the first container via a nozzle with a dia. sufficiently large for the effects of the tides to be negligible. The movable wall section of the first container is provided by an expandable membrane, while the flexible walls of the second container are provided by a non-expandable membrane. Pref. the third container is coupled to a piston-cylinder device, with the piston moved in accordance with the pressure within the third container. A temp. compensation is provided automatically by the effects of the water pressure on the second container.

"Vorrichtung zur Umwandlung der Energie von "Device for converting the energy of

Meereswellen in elektrische Energie Das Hauptpatent ... (Anmeldung P 28 36 856.1) betrifft eine Vorrichtung zur Umwandlung der Energie von Meereswellen in elektrische Energie, bestehend aus einem unter Wasser befindlichen, vorzugsweise auf dem Meeresgrunde ruhenden ersten Behälter mit mindestens einem beweglichen (weitgehend) unabhängig von den Gezeiten um einen (weitgehend) festen Punkt schwingenden Wandteil, einem zweiten Behälter mit einem beweglichen, gegen in diesem befindliches Gas, insbesondere Luft, arbeitenden Wandteil,, einer Düse zwischen dem zweiten Behälter und einem dritten Behälter, deren Durchmesser so groß ist, daß sich über sie praktisch nur Druckschwankungen aufgrund der Gezeiten in den dritten Behälter auswirken können. Ocean waves in electrical energy The main patent ... (registration P 28 36 856.1) relates to a device for converting the energy of ocean waves in electrical energy consisting of a submerged, preferably first container resting on the seabed with at least one movable (largely) independent of the tide around a (largely) fixed point swinging wall part, a second container with a movable gas located in it, in particular air, working wall part ,, a nozzle between the second container and a third container, the diameter of which is so large that it is practical to use only pressure fluctuations due to the tides can affect the third container.

Gemäß einem Ausführungsbeispiel der Erfindung nach dem Hauptpatent arbeitet das bewegliche Wandteil des ersten Behälters gegen eine Feder, der dritte Behälter ist mit einem Zylinder verbunden, dessen Kolben von dem Druck in dem dritten Behälter hin- und herverschoben wird und mit dem Fuß der Feder verbunden ist, derart, daß die Feder bei Flut zusammengedrückt wird.According to an embodiment of the invention according to the main patent the movable wall part of the first container works against a spring, the third Container is connected to a cylinder, the piston of which is affected by the pressure in the third Container is pushed back and forth and is connected to the foot of the spring in such a way that that the spring is compressed at high tide.

Der Erfindung liegt die Aufgabe zugrunde, dieses Ausführungsbeispiel zu vereinfachen.The invention is based on the object of this embodiment to simplify.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das bewegliche Wand teil des ersten Behälters gegen in diesem befindliches Gas, insbesondere Luft, arbeitet, der dritte Behälter identisch mit dem ersten Behälter ist, das bewegliche Wandteil des ersten Behälters eine elastische Membran und das bewegliche land teil des zweiten Behälters unelastisch ist.This object is achieved in that the movable Wall part of the first container against gas located in this, in particular air, works, the third container is identical to the first container, the movable one Wall part of the first container an elastic membrane and the movable land part of the second container is inelastic.

Diese Ausfiihrungsform ist nicht nur einfacher als das Ausfiihrungsbeispiel gemäß dem Hauptpatent, hinzu kommt, daß es eine Temperaturkornpensation ermöglicht.This embodiment is not only simpler than the embodiment according to the main patent, added that it enables a temperature compensation.

In der einzigen Figur der Zeichnung ist ein Ausführungsbeispiel veranschaulicht.In the single figure of the drawing, an embodiment is illustrated.

Darin ist mit 1 ein erster Behälter, mit 2 eine den zweiten Behälter darstellende, in sich geschlossene flexible Blase, die zumindest in ihrem Arbeitsbereich unelastisch ist, mit 3 eine Düse und mit 4 eine elastische Membran bezeichnet. Beide Behälter 1 und 2 sind mit Luft gefüllt. der Durchmesser der Düse 3 ist so groß, daß sich iiber sie aus der Blase 2 in den Behälter 1 praktisch nur Druckschwankungen aufgrund der Gezeiten (nicht aber aufgrund der içrellenbewegungen) auswirken können.In it is with 1 a first container, with 2 a second container performing, self-contained flexible bladder that is at least in its working area is inelastic, 3 denotes a nozzle and 4 denotes an elastic membrane. Both Trays 1 and 2 are filled with air. the diameter of the nozzle 3 is so large, that there are practically only pressure fluctuations via it from the bladder 2 into the container 1 due to the tides (but not due to the movements of the içrellen).

Die Membran 4 folgt infolgedessen nur den Wellenbewegungen und nicht den Gezeiten.The membrane 4 consequently only follows the wave movements and not the tide.

Man kann sich diesen Sachverhalt folgendermassen klar machen: Wenn keine Wellenbewegungen vorhanden sind, ist in der Blase 2 und in dem Behälter 1 stets ein Druck, der dem Druck außerhalb der Vorrichtung entspricht, und von den Gezeiten abhängt. Die Blase 2 ist bei Flut mehr zusammengedrückt als bei Ebbe. Die Membran 4 hat unabhängig von Ebbe und Flut stets ihre gleiche ebene Erstreckung. Bei Druckschwankungen aufgrund von Wellenbewegungen findet ein Druckausgleich von der Blase 2 in den Behälter 1 iiber die Düse 3 nicht statt. Es ist in bezug auf Wellenbewegungen so, als ob der Behälter 1 nicht mit der Blase 2 verbunden wäre. Die Membran 4 schwingt dann hin und her und somit, wie gewollt, stets um den gleichen Punkt.One can make this fact clear to oneself as follows: If there are no undulations is in the bladder 2 and in the container 1 always a pressure that corresponds to the pressure outside the device, and of the Tide depends. Bladder 2 is more compressed at high tide than at low tide. the Membrane 4 always has the same plane extension regardless of the ebb and flow. In the event of pressure fluctuations due to wave movements, there is a pressure equalization of the bubble 2 into the container 1 via the nozzle 3 does not take place. It is related to Wave movements as if the container 1 was not connected to the bladder 2 were. The membrane 4 then swings back and forth and thus, as intended, always around the same Period.

Die Temperaturkompensation kann man sich folgendermassen erklären: Aufgrund einer Temperaturerniedrigung zieht sich die Luft in dem Behälter 1 und der Blase 2 zwar zusammen, jedoch entsteht dadurch keine Druckverminderung im Innern des Behälters 1 und der Blase 2. Vielmehr drückt der Wasserdruck die Blase 2 so weit zusammen, bis innen und außen wieder der gleiche Druck herrscht. Die Membran ändert also auch aufgrund von Temperaturänderungen nicht ihre Lage.The temperature compensation can be explained as follows: Due to a decrease in temperature, the air in the container 1 and is drawn of the bladder 2 together, but this does not result in any pressure reduction in the interior of the container 1 and the bladder 2. Rather, the water pressure pushes the bladder 2 so far together until there is the same pressure inside and outside again. The membrane does not change its position due to temperature changes.
