Abstract
Description
Die Erfindung betrifft ein Strömungskraftwerk zur Umwandlung von kinetischer Energie eines Fluids in elektrische Energie.The The invention relates to a flow power plant for Conversion of kinetic energy of a fluid into electrical energy.
Strömungskraftwerke, die die kinetische Energie eines Fluids, insbesondere der Atmosphärenluft oder von Wasser, in elektrische Energie umwandeln, sind bereits in vielfältiger Weise seit Jahren im Einsatz und erlangen aufgrund der weitgehend kohlendioxidfreien Erzeugung von elektrischer Energie immer größere Bedeutung. So sind beispielsweise Windräder weit verbreitet, Wasserkraftwerke werden an Stauseen oder fließenden Gewässern gebaut und Gezeitenkraftwerke nutzen die Meeresströmung. Allen bekannten Strömungskraftwerken ist jedoch das Merkmal gemein, dass ihre Turbine starr mit dem Untergrund verbunden ist. So ist ein Windrad auf einem festen Sockel montiert, während die Turbinen von Gezeitenkraftwerken und Fließwasserkraftwerken in einem festen Fundament am Meeresboden oder am Boden eines Flusses installiert sind. Der Bau solcher Fundamente und Sockel ist aufwendig und daher ein erheblicher Kostenfaktor. Soll das Strömungskraftwerk für variierende Strömungsrichtungen eines Fluids ausgelegt werden, so sind hierfür ebenfalls aufwendige Vorkehrungen zu treffen, wie beispielsweise eine drehbare Lagerung des Windrades auf seinem Sockel.Current power plants, the kinetic energy of a fluid, in particular the atmospheric air or of water, to convert into electrical energy, are already in more diverse Way in use for years and gain due to the largely carbon dioxide-free generation of electrical energy is becoming increasingly important. For example, wind turbines Widespread, hydroelectric power plants are built on reservoirs or flowing waters and tidal power plants use the ocean current. All known current power plants However, the common feature is that their turbine is rigid with the ground connected is. So a windmill is mounted on a solid base, while the turbines of tidal and hydropower plants in one solid foundation installed on the seabed or at the bottom of a river are. The construction of such foundations and sockets is expensive and therefore a significant cost factor. Should the flow power plant for varying flow directions be designed a fluid, so this is also expensive precautions to meet, such as a rotatable mounting of the wind turbine on his pedestal.
Es ist daher Aufgabe der Erfindung, ein Strömungskraftwerk bereitzustellen, das weniger aufwendig zu installieren ist.It is therefore an object of the invention to provide a flow power plant, which is less expensive to install.
Diese Aufgabe wird erfindungsgemäß durch ein Strömungskraftwerk mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.These The object is achieved by a Current power plant solved with the features of claim 1. Advantageous developments are the subject of the dependent Claims.
Der Erfindung liegt der Gedanke zugrunde, mittels des Ankers eine einfache Befestigungsmöglichkeit für das Strömungskraftwerk am Boden zu schaffen. Aufwendige Vorarbeiten wie die Erstellung eines Fundaments sind dabei nicht erforderlich. Der Auftriebskörper sorgt dafür, dass die Turbineneinheit in einer Höhe über dem Boden gehalten wird, in der eine ausreichende Strömung des Fluids vorhanden ist. Durch die bewegliche Befestigung der Turbineneinheit am Boden mittels des Ankers und des Ankerseils oder der Ankerkette ist diese zudem in der Lage, selbsttätig ihre Ausrichtung zu verändern, um sich an wechselnde Strömungsrichtungen des Fluids anzupassen.Of the Invention is based on the idea, by means of the anchor a simple mounting option for the Current power plant to create on the ground. Elaborate preparatory work such as the creation of a Foundations are not required. The buoyancy body provides for this, that the turbine unit is kept at a height above the ground, in the sufficient flow of the fluid is present. By the movable attachment of the turbine unit on the ground by means of the anchor and the anchor rope or the anchor chain It is also able to change its direction automatically to changing flow directions to adapt to the fluid.
Es wird bevorzugt, dass der Generator starr mit der Turbineneinheit verbunden ist und dass der Auftriebskörper eine solche Dichte aufweist, dass er die Turbineneinheit und den Generator im Fluid über dem Boden in der Schwebe hält. Die starre Verbindung zwischen dem Generator und der Turbineneinheit erleichtert die Kraftübertragung von der Turbine auf den Generator. Insbesondere können an sich bekannte Getriebe für diese Kraftübertragung eingesetzt werden.It it is preferred that the generator be rigid with the turbine unit is connected and that the buoyant body has such a density, that he the turbine unit and the generator in the fluid above the Holding ground in the balance. The rigid connection between the generator and the turbine unit facilitates the transmission of power from the turbine to the generator. In particular, you can known transmission for this power transmission be used.
Gemäß einer ersten Ausführungsform ist der Auftriebskörper starr mit der Turbineneinheit verbunden und vorzugsweise in sie integriert. Insbesondere kann der Auftriebskörper eine Anzahl von gasgefüllten Auftriebskammern aufweisen, so dass das Strömungskraftwerk beim Einsatz im Wasser nach Art eines U-Boots, beim Einsatz in der Atmosphärenluft nach Art eines Luftschiffs ausgebildet ist.According to one first embodiment is the buoyant body rigidly connected to the turbine unit and preferably in it integrated. In particular, the buoyant body may include a number of gas-filled buoyancy chambers have, so that the flow power plant When used in water like a submarine, when used in the Atmosphere air after Art of an airship is formed.
Gemäß einer zweiten Ausführungsform ist die Turbineneinheit mittels mindestens eines Tragseils und/oder mindestens einer Tragkette mit dem Auftriebskörper verbunden, der somit über der Turbineneinheit schwebt. Bei der Verwendung des Strömungskraftwerks im Wasser kann der Auftriebskörper ein an der Wasseroberfläche schwimmender Schwimmer sein, unter dem die Turbineneinheit am Tragseil oder der Tragkette hängt und vollständig unter Wasser getaucht ist. Es ist jedoch auch möglich, dass der Auftriebskörper sich ebenfalls unter der Wasseroberfläche befindet, indem das Ankerseil oder die Ankerkette sowie das Tragseil bzw. die Tragkette entsprechend kurz gehalten sind. Befindet sich der Auftriebskörper als Schwimmer an der Wasseroberfläche, so kann der vom Generator erzeugte elektrische Strom auf einfache Weise mittels einer Leitung zum Schwimmer und von diesem mittels eines elektrischen Anschlusses zum Verbraucher abgeleitet werden. Bei einer Verwendung des Strömungskraftwerks in der Atmosphäre kann der Auftriebskörper zweckmäßig ein Ballon sein, der die Turbineneinheit in der Luft in der Schwebe hält. Der Anker kann prinzipiell am Boden fixiert sein oder lediglich auf dem Boden aufliegen und die Turbineneinheit aufgrund seines Gewichts in der gewünschten Position halten.According to one second embodiment is the turbine unit by means of at least one support cable and / or at least one carrying chain connected to the buoyant body, thus over the Turbine unit floats. When using the flow power plant in the water, the buoyant body one at the water surface floating float, under which the turbine unit on the carrying rope or the carrying chain hangs and completely submerged under water. However, it is also possible that the buoyant body itself also under the water surface located by the anchor rope or the anchor chain as well as the suspension rope or the carrying chain are kept correspondingly short. Is the buoyancy as a float on the water surface, so can the generator generated electric power in a simple manner by means of a line to the float and of this by means of an electrical connection be derived to the consumer. When using the flow power plant in the atmosphere can the buoyant body appropriate one Be the balloon that holds the turbine unit in the air in the air holds. Of the Anchor can basically be fixed to the ground or just on the ground Floor rest and the turbine unit due to its weight in the desired Hold position.
Um eine vorteilhafte Stellung der Turbineneinheit zu erzielen, in der das Strömungsrohr weitgehend horizontal ausgerichtet ist, wird bevorzugt, dass zwischen der Turbineneinheit und dem Auftriebskörper mindestens zwei Tragseile und/oder Tragketten gleicher Länge angeordnet sind, die paarweise in etwa gleichen Abständen zum Schwerpunkt der Turbineneinheit an einander diametral gegenüberliegenden Stellen an der Turbineneinheit befestigt sind. Das gleiche Ergebnis kann dadurch erzielt werden, dass in entsprechender Weise zwischen der Turbineneinheit und dem Anker mindestens zwei Ankerseile und/oder Ankerketten gleicher Länge angeordnet sind. Es können auch zwei oder mehr Anker vorgesehen sein, die bevorzugt in entsprechender Weise mit der Turbineneinheit verbunden sind. Eine weitere oder alternative Möglichkeit der Stabilisierung der Turbineneinheit mit horizontaler Ausrichtung des Strömungsrohrs besteht darin, die Turbineneinheit mit mindestens zwei an einander abgewandten Seiten vorstehenden Tragflächen auszustatten.In order to achieve an advantageous position of the turbine unit, in which the flow tube is oriented substantially horizontally, it is preferred that at least two support cables and / or support chains of the same length are arranged between the turbine unit and the buoyant body, the pairs in about equal distances to the center of gravity of the turbine unit attached to diametrically opposite locations on the turbine unit. The same result can be achieved that are arranged in a corresponding manner between the turbine unit and the armature at least two anchor ropes and / or anchor chains of equal length. It can also be provided two or more anchors, which are preferably connected in a corresponding manner with the turbine unit. Another or alternative way of stabilization The turbine unit with horizontal alignment of the flow tube is to equip the turbine unit with at least two sides facing away from each other on projecting wings.
