Schwimmbecken für das Gegenstrom-schwi en.Swimming pool for countercurrent swimming.
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Konstruktion eines Gegenstromschwimmanlage in einem Schwimmbecken .The invention relates to a construction of a countercurrent swimming system in a swimming pool.
Stand der TechnikState of the art
In der Gegenwart ist nur ein System bekannt, dessen Prinzip eine Anlage fürs Gegenstromschwimmen ist.Im Prinzip handelt es sich um die Ausnutzung einer Hochleistungsumlaufpumpe, die in relativ kleinen Basins einen Wasserstrom zu bilden ermöglicht, dementgegen es dann möglich ist, längere Zeit in leichtem Tempo zu schwimmen.In der Nähe von der Eingangsdüse kann man auch kraulen. ( Publikation: Jan Struska & Kol., "Wir bauen Familienhäuser", siehe Seite 120, vom Jahr. 1989 )In einer Öffnung wird das Wasser mittels Hilfe einer Hochleistungsumlaufspumpe angesaugt, damit es anschliessend unter dem Wasserspiegel zurück ins Schwimmbecken geführt wird.Die modernsten Systeme (nach der Firmenliteratur der Firma Krülland) benötigen keine Öffnungen in der Wand des Schwimmbeckens, sondern werden einfach auf die flache Kante des Schwimmbeckens befestigt.Der wichtige Teil dieser Anlage ist die Ausgangsdüse, die die Wassergeschwindigkeit und die Menge des strömenden Wassers gewährleisten muss.Die Grundidee des Systems fürs Gegenstromschwimmen ist in der Verbesserung der auf Prinzipien der Umlaufspumpe gegründeten Anlage.At present, only one system is known, the principle of which is a system for countercurrent swimming. In principle, it is the use of a high-performance circulation pump that enables a water flow to be formed in relatively small basins, whereas it is then possible to do so at a slow pace for a long time You can also swim near the inlet nozzle. (Publication: Jan Struska & Kol., "We are building family houses", see page 120, from 1989) The water is sucked into an opening by means of a high-performance circulation pump so that it is then led back into the swimming pool below the water level Systems (according to the Krülland company literature) do not require openings in the wall of the swimming pool, but are simply attached to the flat edge of the swimming pool.The important part of this system is the outlet nozzle, which must ensure the water speed and the amount of flowing water. The basic idea of the system for countercurrent swimming is to improve the system based on the principles of the circulation pump.
Als Nachteil dieses Systems kann man die Tatsache beurteilen, dass der Schwimmer sich immer gegen den aus der Düse strömenden Wasserstrom orientieren muss, und diese Richtung im Laufe des Schwimmens ständig einhalten muss. Das Stromzentrum befindet sich 0,15 m unter dem Wasserspiegel. Der Schwimmer befindet sich im Gegenstrom, wo die Strömung turbulent ist. Aus diesem Grunde muss er einen gewissen Abstand von der Ausgangsdüse ständig einhalten, weil dort der Wasserspiegel nicht so stürmisch ist. Damit hängen auch Anforderungen an die Länge des Behälters zusammen.Moderne Anlagen stellen hohe Ansprüche an die Erzeugung und der Leistungsbedarf ist nicht zu vernachlässigen.A disadvantage of this system can be seen in the fact that the swimmer must always orientate himself against the water stream flowing out of the nozzle, and must constantly keep this direction in the course of swimming. The electricity center is 0.15 m below the water level. The swimmer is in countercurrent where the flow is turbulent. For this reason, he must keep a certain distance from the outlet nozzle, because the water level is not so stormy there. This also has to do with the requirements for the length of the container. Modern systems place high demands on production and the power requirement should not be neglected.
Wesen der ErfindungEssence of the invention
Diese Nachteile des Stromschwimmbeckens für das Gegenstromschwimmen sind gegenüber einem konventionellen Becken dahingehend gelöst, dass der Boden doppelgestaltet ist, verbreitet sich in der Stromrichtung, dieser geht in bogen- oder spiralen Form an der Stirnwand hoch, womit ein hydrodynamischer Kanal mit einem kleinem hydraulischen Widerstand für den gleichgerichteten Wasserstrom gebildet wird.These disadvantages of the current swimming pool for countercurrent swimming are solved compared to a conventional pool in that the bottom is double-shaped, spreads in the direction of the current, this goes up in an arch or spiral shape on the front wall, which means a hydrodynamic channel with a small hydraulic resistance for the rectified water flow is formed.
Die wasserstrombildende Anlage ist in einem konischen Schacht an dem hinteren Teil des Schwimmbeckens, zwischen der Trennwand und hinteren Stirnwand, entweder vertikal, oder horizontal lokalisiert.Diese Anlage muss nicht auf den Prinzipiens der Umlaufspumpe basieren, also auf dem Effekt des Einsaugens und Hinauspressens des Wassers. Die Konstruktion des Schwimmbeckens schliesst nicht die Benutzung einer Anlage auch auf diesem Prinzip aus.Die wasserstrombildende Anlage beinhaltet als Wirbelquelle eine Schiffschraube.The water flow generating system is located in a conical shaft on the rear part of the swimming pool, between the partition and the rear end wall, either vertically or horizontally. This system does not have to be based on the principles of the circulation pump, i.e. on the effect of sucking in and squeezing out the water . The construction of the swimming pool does not exclude the use of a system based on this principle. The water flow-generating system contains a propeller as a vortex source.
Für die Regulation der Parameter des Strömens dient die Regulationsklappe auf der bogen - oder spiralenförmigen vorderen Stirnwand und der hinausschiebbare Teil der Trennwand, der den Schwimmraum von dem Schacht trennt, wo sich die strombildende Anlage befindet. Ausserdem ist es möglich, die Regulierung mittels Drehzahlsveränderung der strombildenden Anlage durchzuführen. Auflistung der Bildern auf den ZeichnungenThe regulation flap on the arch - or spiral - shaped front end wall and the part of the partition that can be pushed out, which separates the swimming area from the shaft where the current generating system is located, are used to regulate the flow parameters. It is also possible to carry out the regulation by changing the speed of the current-generating system. List the images on the drawings
