Abstract

A hollow tube has its bottom end open and submerged. It has a float round it to keep it partly under and partly above the water line and is attached to an anchor so that it can pivot about a point below the water line. A compartment at the top of the tube contains two air motors connected by free wheel couplings to a generator. Movement of the water surface within the tube forces air through non return valves into and out of the machine compartment. As it flows in it drives the air motor and as it flows out it drives the other.

Description

Gerät zur Umwandlung meeresspezifischer Energie,Device for converting sea-specific energy,

wie Düngung bzw. Wellengang und Gezeitenunterschiede Aufgabe der Erfindung ist eine möglichst direkte sowie umweltschonende Umwandlung der der Düngung bzw. dem Wellengang und den Gezeiten innewohnenden Energie in verbrauchsfähige Energie auf wirtschaftliche Art und Weise.such as fertilization or waves and tide differences object of the invention is a direct and environmentally friendly conversion of the fertilization or the waves and tides inherent energy into consumable energy in an economical way.

Das zur Lösung der gestellten Aufgabe entwickelte Gerät besteht im wesentlichen aus einem Rohr 1 mit einem an seinem unteren Ende angebauten Schwimmkörper 2. Im oberen Teil des nach unten offenen Rohres 1 ist der Maschinenraum 3 eingebaut, der Außenlüftung besitzt, und in dem Druckluftmaschinen 4 sowie der Energieerzeuger 5 untergebracht sind. Beide Druckluftmaschinen 4 stehen jeweils mittels eines Rückschlagventiles 6 mit dem Wasserraum 7 in Verbindung. Die Rückschlagventile 6 sind gegensinnig eingebaut. Auch die Druckluftmaschinen 4 sind gegensinnig gebaut und laufen somit in einer Drehrichtung um. Sie sind mit Überholkupplungen (Freilauf) ausgerüstet.The device developed to solve the task at hand consists of the essentially of a tube 1 with a floating body attached to its lower end 2. The machine room 3 is installed in the upper part of the pipe 1, which is open at the bottom, the external ventilation has, and in the compressed air machines 4 and the energy generator 5 are housed. Both compressed air machines 4 are each by means of a check valve 6 with the water space 7 in connection. The check valves 6 are in opposite directions built-in. The compressed air machines 4 are also built in opposite directions and thus run in one Direction of rotation. They are equipped with overrunning clutches (freewheel).

Zur Befestigung des vorgeschlagenen Gerätes am Meeresgrund dient eine bewegliche Verankerung 8 mit einem Ankergewicht 9. Die Befestigung dieser Verankerung 8 am Gerät erfolgt an drei Punkten. Das Gerät ist ohne Verankerung freischwimmend mit Reserveauftrieb (Freibord am Schwimmkörper), jedoch ist in diesem Zustand eine Stabilität weder sicher noch nötig. Der Schwimmkörper 2 ist flut- und lenzbar.To attach the proposed device to the seabed is used movable anchorage 8 with an anchor weight 9. The attachment of this anchorage 8 on the device takes place at three points. The device is free-floating without anchoring with reserve buoyancy (freeboard on the float), but in this state there is a Stability neither safe nor necessary. The floating body 2 can be flooded and drained.

ursächlich für die Punktion des erfindungsgemäßen Gerätes ist die Installation, sie wird deshalb als der Funktion zugehörig beschrieben.the cause of the puncture of the device according to the invention is the Installation, therefore it is described as belonging to the function.

Das Gerät wird an einem dafür geeigneten Platz im Meer mittels der beweglichen Verankerung 8 und dem Ankergewicht 9 mit einem konstanten Abstand (Änderungen durch Driften sind unerheblich) vom Meeresgrund derart befestigt, daß der Schwimmkörper 2 noch ein gewisses Maß unter dem niedrigsten zu erwartenden Wasserstand liegt und damit ein nermanenter Auftrieb (Reserveauftrieb) auch bei niedrigem Wasserstand vorhanden ist. Zusammen mit der nicht dehnbaren beweglichen Verankerung 8 und dem Ankergewicht. 9, welches den Reserveauftrieb mehr als ausgleichen m1l3, ist der konstante Abstand gewährleistet.The device is installed in a suitable place in the sea using the movable anchorage 8 and the anchor weight 9 with a constant distance (changes by drifting are insignificant) attached to the seabed in such a way that the float 2 is still a certain amount below the lowest expected water level and thus a permanent buoyancy (reserve buoyancy) even at low levels Water level is available. Together with the non-stretchable movable anchorage 8 and the Anchor weight. 9, which more than offset the reserve buoyancy m1l3, is the constant distance guaranteed.

Über den außenbelüfteten Maschinenraum 3 und abwechselnd eine der beiden Druckluftmaschinen 4 mit ihren Rückschlag ventilen 6 ist der Wasserraum 7 mit der Atmosphäre verbunden. Das Wasser steigt und fällt also im Wasserraum 7 ebenso wie außerhalb des Gerätes. Dadurch bläst der Wasserraum 7 abwechselnd Luft ab und saugt Luft an, so daß die Druckluftmaschinen 4 betrieben werden und ihrerseits den Energieerzeuger 5 antreiben.Via the externally ventilated machine room 3 and alternately one of the The water space 7 is the two compressed air machines 4 with their check valves 6 connected to the atmosphere. The water rises and falls in the water space 7 as well like outside the device. As a result, the water space 7 alternately blows off air and sucks in air, so that the compressed air machines 4 are operated and in turn the Drive energy generator 5.

Der Aufbau des neuartigen Gerätes ist äußerst widerstandsfähig sowie einfach, und läßt sich wirtschaftlich herstellen. Außerdem ist das Gerät durch wenige Verschleiteile wartungsfreundlich. Die Anordnung der Maschinen erlaubt es, das Aggregat als eine Einheit auszuwechseln.The construction of the novel device is extremely tough as well simple and economical to manufacture. In addition, the device is by few Wear parts easy to maintain. The arrangement of the machines allows the unit to be exchanged as a unit.

Mit Absicht wurde wegen der Gefahr der Verschmutzung der Ventile und Kraftmaschinen darauf verzichtet, unmittellzr.tr das Wasser zum Antrieb auszunutzen.Was purposely because of the risk of contamination of the valves and Power machines refrain from using the water directly for propulsion.
