Description

Vorrichtung zur Sauerstoffanreicherung unterer Schichten stehender GewässerDevice for oxygen enrichment of lower layers of standing water
Beschreibungdescription
Die vorliegende Erfindung betrifft eine Vorrichtung zur Sauerstoffanreicherung unterer Schichten stehender Gewässer.The present invention relates to a device for oxygenating lower layers of standing water.
Untersuchungen bei zahlreichen Baggerseen haben ergeben, daß bedingt durch bestimmte Einflußfaktoren wie Lage, Beschattung, Laubeintrag oder schlechtem Windfall die Mächtigkeit sauerstofffreier unterer Gewässerschichten zunimmt und durch die natürliche Umwälzung in den Wintermonaten nicht mehr ausgeglichen wird. In Einzelfallen waren bis zu 2/3 einer entnommenen Wassersäule stauerstoffrei. Dies führt zu einer starken Belastung der in dem Gewässer angesiedelten Lebewesen führen, den Artenreichtum stark beeinträchtigen und schließlich im vollständigen Umkippen des Gewässers enden.Studies on numerous quarry ponds have shown that due to certain influencing factors such as location, shading, leaves or bad windfall, the thickness of oxygen-free lower water layers increases and is no longer compensated for by the natural upheaval in the winter months. In individual cases up to 2/3 of a removed water column were free of fuel. This leads to a heavy load on the creatures living in the body of water, severely impair the richness of species and ultimately end up in the complete overturning of the body of water.
Da diese Problematik seit Jahren bekannt ist, hat es nicht an Versuchen gefehlt, Vorrichtungen zur Verbesserung der Wasserqualität einzusetzen. Aus der DE-U- 296 07 656 sind beispielsweise durch Auftriebskörper schwebend in Gewässern angeordnete Rohrleitungen bekannt, über die Druckluft in die Tiefe des Gewässers abgegeben wird. Ein unter dem Wasserspiegel stehendes Gehäuse mit einem Kissen aus Gasgemisch in dessen Bereich umgewälztes Wasser versprüht wird, zeigt dieDE-U-297 08 404. Ein serpentinenartiges Aufsteigen von am Gewässerboden eingepumpter Luft erlaubt eine Vorrichtung gemäß DE-U-298 11 813. Weitere Vorrichtungen mit Pumpen zum Eintrag von Luft zeigen die DE-A- 198 01 238 und die DE-U-297 04 943.Since this problem has been known for years, there has been no lack of attempts to use devices for improving the water quality. From DE-U-296 07 656, for example, pipelines floating in water by means of buoyancy bodies are known, via which compressed air is released into the depth of the water. DE-U-297 08 404 shows a housing standing under the water level with a cushion of gas mixture in the area of which circulated water is sprayed. A serpentine-like rise of air pumped in at the bottom of the water allows a device according to DE-U-298 11 813. Further devices with pumps for the introduction of air show DE-A-198 01 238 and DE-U-297 04 943.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Sauerstoffanreicherung unterer Schichten stehender Gewässer zu schaffen, die einfach im Aufbau ist, die möglichst wenig Versorgungszuleitungen benötigt, die nur minimal in das Gewässer eingreift, die möglichst leise arbeitet und die flexibel an vielen Orten einsetzbar ist.The object of the present invention is to provide a device for the oxygenation of lower layers of standing water is simple in construction, requires as few supply lines as possible, intervenes minimally in the water, works as quietly as possible and can be used flexibly in many places.

Die Schaufelrührer fördern Wasser aus tieferen Gewässerschichten durch das Rohr nach oben. Das Wasser tritt aus dem Rohr heraus und bricht über den Rand des Rohrs. Dieser Effekt führt zu einer Anreicherung des Wassers mit Sauerstoff. Der Weg ist der Natur nachempfunden, wo diese Anreicherung bei Fließgewässern durch die Brechung über Untiefen und Ufer erfolgt.According to the invention, a device for oxygenating lower layers of standing water consists of a pipe vertically inserted into a water, a shaft rotating in the pipe, a drive means for the shaft, at least one paddle stirrer fastened in the pipe to the shaft with at least two rising blades and a holding device for the pipe, the holding device holding the upper end of the pipe above the water level. The paddle stirrers convey water from deeper water layers up through the pipe. The water comes out of the pipe and breaks over the edge of the pipe. This effect leads to an enrichment of the water with oxygen. The path is modeled on nature, where this enrichment in flowing waters takes place through the refraction over shallows and banks.
Nach einer Ausführung der Erfindung ist die Haltevorrichtung an einer fest verankerte Vorrichtung angeordnet, wobei Sensoren zur Erfassung der Höhe des Wasserspiegels vorhanden sind, sowie Mittel zur vertikalen Verstellung des Rohrs.According to one embodiment of the invention, the holding device is arranged on a firmly anchored device, sensors for detecting the height of the water level are present, as well as means for vertical adjustment of the pipe.

Vorteilhafterweise ist an dem unteren Ende der Welle ein gewuchteter Stabilisierungsrührer angeordnet. Vorzugsweise sind wenigstens zwei in einem Abstand voneinander angeordnete Schaufelrührer mit jeweils 4 steigenden Blättern an der Welle befestigt.A balanced stabilizing stirrer is advantageously arranged at the lower end of the shaft. Preferably, at least two paddle stirrers arranged at a distance from one another, each with 4 rising blades, are attached to the shaft.
Die Antriebsmittel für die Welle bestehen vorzugsweise aus einem Elektromotor und einem regelbaren Getriebe. Vorteilhafterweise ist das Getriebe in einem Bereich von zwischen 50 und 110 Umdrehungen/Minute stufenlos regelbar.The drive means for the shaft preferably consist of an electric motor and an adjustable gear. The transmission is advantageously infinitely variable in a range between 50 and 110 revolutions / minute.
Nach einer vorteilhaften Ausführung der Erfindung weist das Getriebe eine Steuerung zur automatischen Regelung der Umdrehung auf und die Steuerung reagiert auf Signale eines Meßinstruments, das die Fördergeschwindigkeit des Wassers in dem Rohr mißt.According to an advantageous embodiment of the invention, the transmission has a control for automatically regulating the rotation and the control reacts to signals from a measuring instrument which measures the conveying speed of the water in the pipe.
Vorzugsweise ist die Welle in einem Kegelwälzlager zum Abfangen der axialen Kräfte, sowie einem oder Kugellager zur Kompensation radialer Kräfte gelagert. Sie braucht sich nur in einem oberen Abschnitt des Rohrs erstrecken.The shaft is preferably mounted in a tapered roller bearing for absorbing the axial forces, and in one or ball bearings for compensating radial forces. It only needs to extend in an upper section of the tube.
Die Vorrichtung gemäß der zweiten Ausfuhrung der Erfindung ist beispielsweise an einem mehrere Schwimmkörper verbindenden Gestell angeordnet. Die Schwimmkörper sind vorteilhafterweise flutbar und entleerbar. Vorteilhafterweise ist eine Beleuchtung und/oder ein Signallicht vorhanden.The device according to the second embodiment of the invention is arranged, for example, on a frame connecting several floating bodies. The floating bodies are advantageously floodable and can be emptied. An illumination and / or a signal light is advantageously present.
Nach einer besonderen Ausführung der Erfindung erfolgt die Stromversorgung photovoltaisch. Der Elektromotor ist dann vorzugsweise ein Gleichstrommotor und es sind Mittel zur Speicherung nicht benötigter elektrischer Energie vorhanden, wobei diese Mittel Gleichstrom abgeben, wenn die photovoltaische Versorgung nachläßt.According to a special embodiment of the invention, the power supply takes place photovoltaically. The electric motor is then preferably a direct current motor and there are means for storing electrical energy that is not required, these means delivering direct current when the photovoltaic supply is weakening.
Im folgenden wird die Erfindung anhand einer Zeichnung beispielhaft näher beschrieben.The invention is described in more detail below by way of example with reference to a drawing.
Fig. 1 zeigt eine schematische Darstellung einer Vorrichtung 1 zur Sauerstoffanreicherung unterer Schichten stehender Gewässer. Diese besteht aus einem länglichen Rohr 2, beispielsweise mit einem Innendurchmesser von 50 cm und einer Länge von 20 m. Das Rohr 2 besteht vorzugsweise aus einem witterungsbeständigen Kunststoff. In dem Rohr ist eine rotierende Welle 3 angeordnet, die oben aus dem Rohr 3 herausgeführt ist und dort an eine mit ihr fluchtende Lagerwelle 8 angeflanscht ist. Die Lagerwelle 8 ist mit Wälz- und Kugellagern in einem Lagerbock 17 gelagert und wird von einer Antriebswelle 7 angetrieben, die wiederum von Antriebsmitteln angetrieben wird, die aus einem stufenlos regelbaren Getriebe 6 und einem Elektromotor 5 bestehen, die an einem über dem Lagerbock 17 angeordneten Rahmengehäuse 9 befestigt sind. Das Rahmengehäuse 9 kann ein Beleuchtungsmittel aufnehmen. Das Rahmengehäuse 9 und der Lagerbock 17 sind fest auf einer Plattform 10 montiert, die gitterartig aufgebaut sein kann. Die Plattform 10 ruht auf mit dieser verbundenen Schwimmkörpern 12. Die Schwimmkörper 12 werden unten von Rahmenteilen 11 umfaßt, die von der Plattform 10 ausgehen, was hier nicht näher dargestellt ist. Das Rohr 2 wird durch eine rohrformige Rohrhalterung 13 in der vertikalen Stellung gehalten. Die Rohrhalterung 13 ist fest mit der Plattform 10 verschraubt. Das Rohr 2 ist durch Rohrschellen 14 fest mit der Rohrhalterung 13 verbunden. Es ist hier nur eine Rohrhalterung 13 dargestellt, in der Praxis werden jedoch mindestens zwei solcher Halterungen verwendet, um der Vorrichtung die nötige Stabilität zu verleihen. Auf der Welle 3 sind innerhalb des Rohres 2 in einem Abstand voneinander zwei Schaufelrührer 15 drehfest angeordnet. Die1 shows a schematic representation of a device 1 for oxygenating lower layers of standing water. This consists of an elongated tube 2, for example with an inner diameter of 50 cm and a length of 20 m. The tube 2 is preferably made of a weather-resistant plastic. A rotating shaft 3 is arranged in the pipe, which is led out of the pipe 3 at the top and is flanged there to a bearing shaft 8 aligned with it. The bearing shaft 8 is supported with roller and ball bearings in a bearing block 17 and is driven by a drive shaft 7, which in turn is driven by drive means which consist of a continuously variable transmission 6 and an electric motor 5, which are arranged on one above the bearing block 17 Frame housing 9 are attached. The frame housing 9 can accommodate an illuminant. The frame housing 9 and the bearing block 17 are fixedly mounted on a platform 10, which can be constructed like a lattice. The platform 10 rests on floating bodies 12 connected to it. The floating bodies 12 are enclosed at the bottom by frame parts 11, which extend from the platform 10, which is not shown in more detail here. The tube 2 is held in the vertical position by a tubular tube holder 13. The tube holder 13 is firmly screwed to the platform 10. The pipe 2 is firmly connected to the pipe holder 13 by pipe clamps 14. Only one pipe holder 13 is shown here, but in practice at least two such holders are used to give the device the necessary stability. On the shaft 3, two blade stirrers 15 are arranged in a rotationally fixed manner within the tube 2 at a distance from one another. The
Schaufelrührer 15 besitzen je vier schrägstehende, bei Rotation der Welle 3 im Uhrzeigersinn steigende Blätter 16. An dem unteren Ende der Welle 3 ist ein gewuchteter Stabilisierungsrührer 4 angeordnet. Die Welle 3 ist hier verkürzt dargestellt, besitzt in der Praxis jedoch eine Länge von 2 m bei einem Durchmesser von 5 cm.Paddle stirrers 15 each have four inclined blades 16 that rise clockwise when the shaft 3 rotates. A balanced stabilizing stirrer 4 is arranged at the lower end of the shaft 3. The shaft 3 is shown shortened here, but in practice it has a length of 2 m with a diameter of 5 cm.
Die Vorrichtung 1 wird mit der Schwimmplattform 10, 11, 12 auf einem stehenden Gewässer an Ort und Stelle gebracht, wobei während des Transports das Rohr 2 und die Welle 3 sich in einer horizontalen Lage befinden. Am Einsatzort werden Rohr 2 und Welle 3 in die vertikale Lage gebracht, wodurch das Rohr etwa 20 m in das Wasser hinein reicht. Die Plattform wird in geeigneter Weise verankert. Durch teilweise Flutung der Schwimmkörper und Justierung des Rohrs 2 wird sichergestellt, daß sich die Oberkante des Rohrs 2 etwa 10 cm über dem Wasserspiegel befindet. Der Motor 5 wird eingeschaltet und das Getriebe 6 wird so geregelt, daß die Welle 3 mit einer Umdrehungszahl von zwischen 56 und 98 Umdrehungen pro Minute im Uhrzeigersinn dreht. Mit der Welle 3 drehen sich die Schaufelrührer 15 mit ihren Blättern 16 und fordern Wasser nach oben über die Kante des Rohres 2, wo dieses sich bricht und neben dem Rohr 2 in dasThe device 1 is brought into place with the floating platform 10, 11, 12 on a standing body of water, the tube 2 and the shaft 3 being in a horizontal position during transport. At the place of use, pipe 2 and shaft 3 are brought into the vertical position, whereby the pipe extends about 20 m into the water. The platform is anchored in a suitable manner. Partial flooding of the float and adjustment of the tube 2 ensures that the upper edge of the tube 2 is about 10 cm above the water level. The motor 5 is switched on and the transmission 6 is regulated so that the shaft 3 rotates clockwise at a speed of between 56 and 98 revolutions per minute. With the shaft 3, the paddle stirrer 15 rotates with its blades 16 and requests water upwards over the edge of the tube 2, where it breaks and next to the tube 2 into the
Gewässer zurückfließt. Nach kurzer Zeit ist das geförderte Wasser nur solches aus den 20 m tiefen, sauerstofffreien Schichten. Das Rührwerk kann in 24 Stunden etwa 180.000 Liter Wasser umwälzen.Water flows back. After a short time, the extracted water is only from the 20 m deep, oxygen-free layers. The agitator can circulate around 180,000 liters of water in 24 hours.
Neben der beschriebenen beispielhaften Ausfuhrung kommen einige Alternativen in Betracht. So kann die Vorrichtung auch an einem Boot oder einer Art festem Bauwerk angeordnet sein. Die Zahl der Schaufelrührer muß nicht auf 2 beschränkt sein und die Längenverhältnisse von Rohr und Welle können variieren. In addition to the exemplary embodiment described, there are a few alternatives. So the device can also be arranged on a boat or a type of solid structure. The number of paddle stirrers need not be limited to 2 and the length ratios of the tube and shaft can vary.
