Abstract

For supplying remote water-carrying storage installations such as water towers with electrical energy it is intended by means of water flows to obtain electrical energy from kinetic energy, which is generated on the basis of potential energy in relation to a lower water level. For this purpose the device has a current generator comprising a turbine and a generator, which current generator is arranged in a floatable housing which rests on the lower water level. By virtue of the infeed of the water flowing in above the device, electrical current is generated, which can supply at least the measuring instruments and the lighting fixtures necessary for operation and maintenance.

Description

Verfahren und Vorrichtung zum Gewinnen von elektrischerMethod and apparatus for obtaining electrical

Energie aus kinetischer Energie von Wasserströmungen Die Erfindung betrifft eine Vorrichtung zum Gewinnen von elektrischer Energie aus kinetischer Energie von Wasserströmungen, die aufgrund von potentieller Energie gegenüber einem niedrigeren Wasserspiegel entstehen, mit einem eine Turbine und einen Generator umfassenden Stromerzeuger sowie ein Verfahren zur Erzeugung dieser Energie.Energy from kinetic energy of water currents The invention relates to a device for generating electrical energy from kinetic Energy of water currents due to potential energy opposite one lower water levels arise, with a turbine and a generator comprehensive electricity generator and a method for generating this energy.

In Wasserversorgungsanlagen für das öffentliche Wasserversorgungsnetz ist es beispielsweise üblich, das Wasser in Hochbehältern oder Wassertürmen zu speichern. Durch Pumpwerke oder aus Fernversorgungsleitungen oder auch durch Quelleinläufe wird das Wasser in diese Bauwerke befördert.In water supply systems for the public water supply network For example, it is common to store the water in elevated tanks or water towers. Through pumping stations or from long-distance supply lines or through spring inlets the water is carried into these structures.

Zweckmässig und üblich ist es, das Wasser von oben in den Speicherbehälter einzuführen.It is expedient and customary to pour the water into the storage tank from above to introduce.

Durch das Einführen von Wasser steigt der Wasserspiegel.By introducing water, the water level rises.

Oft wird für die Pumpwerke der preisgünstigere Nachtstromtarif ausgenützt, die Speicherbehälter werden dann über Nacht gefüllt. Infolge von Wasserverbrauch sinkt der Wasserspiegel wieder. Beim Spitzenverbrauch kann der Speicherbehälter fast völlig entleert werden. Der Wasserspiegel schwankt also erheblich, die Höhendifferenz kann mehrere Meter betragen.Often the cheaper night electricity tariff is used for the pumping stations, the storage tanks are then filled overnight. As a result of water consumption the water level sinks again. During peak consumption, the storage tank can almost completely emptied. The water level fluctuates considerably, the difference in altitude can be several meters.

Andererseits benötigen fernabgelegene Speicheranlagen, insbesondere freistehende Wassertürme, elektrische Energie zum Betreiben von Meßinstrumenten und Geräten zum Betrieb und zur Wartung. Diese elektrische Energie wird üblicherweise aus wiederaufzuladenden Batterien oder aus Notstromaggregaten gewonnen. Eine Fernversorgung mit elektrischer Energie ist, soweit sie überhaupt möglich ist, sehr aufwendig. Werden Notstromaggregate eingesetzt, müssen Betriebsstoffe und Schmiermittel im Bereich der Speicheranlage gelagert werden, dies stellt eine potentielle Verschmutzungsgefahr für die Wasserversorung dar.On the other hand, need remote storage facilities, in particular free-standing water towers, electrical energy for operating measuring instruments and equipment for operation and maintenance. This electrical energy is usually Obtained from rechargeable batteries or from emergency power generators. A remote supply with electrical energy, as far as it is possible at all, is very expensive. If emergency power generators are used, operating materials and lubricants must be in the Stored in the area of the storage facility, this poses a potential risk of contamination for the water supply.

Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat dem gegenüber den Vorteil, daß die bisher nicht genutzte mechanische Energie der Wasserzuführung zur Speicheranlage zum Erzeugen elektrischer Energie herangezogen wird. Ein weiterer Vorteil ist, daß die Schwankung des Speichervolumens und damit der Höhe des Wasserspiegels in Speicheranlagen durch die Vorrichtung mit ausgenutzt wird.The device according to the invention with the characterizing features the main claim has the advantage that the previously unused mechanical energy of the water supply to the storage system to generate electrical energy Energy is used. Another advantage is that the fluctuation in the storage volume and thus the height of the water level in storage systems by the device is exploited.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich. Besonders vorteilhaft ist die Anwendbarkeit in einer Vielzahl verschieden gearteter Anlagen Die Verwendung eines Trichters stellt ein sicheres Aufnehmen der den Zulauf verlassenden Wasserströmungen durch den Stromerzeuger sicher, auch wenn der Wasserspiegel auf einen sehr niedrigen Stand abgesunken ist.The measures listed in the subclaims are advantageous Developments and improvements of the device specified in the main claim possible. The applicability in a large number of different ways is particularly advantageous of types of systems Using a funnel makes a safe one The power generator safely absorbs the water currents leaving the inlet, even if the water level has dropped to a very low level.

Mit Hilfe einer Einrichtung zum Führen des Gehäuses in vertikaler Richtung wird verhindert, daß das Gehäuse verkantet oder kippt.With the help of a device for guiding the housing in a vertical direction Direction prevents the housing from tilting or tilting.

Je nach der Art der Speicheranlage kann eine seitliche Ausführung der Wasserströmungen aus dem Gehäuse oder aber ein senkrechter Durchfluß zweckmäßig und vorteilhaft sein.Depending on the type of storage system, a side design can be used the water flows out of the housing or a vertical flow is appropriate and be beneficial.

Die Verbraucher der Speicheranlage können direkt an den Stromerzeuger angeschlossen sein; zusätzlich kann eine Speicherbatterie vorgesehen werden.The consumers of the storage system can be connected directly to the power generator be connected; a storage battery can also be provided.

Bei Speicheranlagen, bei denen sich die Höhe des Wasserspiegels nur wenig ändert, kann eine starre Befestigung des Gehäuses vorteilhaft sein.In storage systems where the height of the water level is only changes little, a rigid attachment of the housing can be advantageous.
