Description

Die Erfindung betrifft eine Vorrichtung zur Reinigung der Oberfläche von Wasserkörpern, beispielsweise Wasser in Swimmingpools oder Schwimmteichen, mit einem Zulaufkanal, in welchem eine das Ausmaß des Wasserzulaufs regelnde schwenkbare Klappe angeordnet ist und welcher mit einem Behälter, in welchem sich ein Sieb befindet, verbunden ist.The invention relates to a device for cleaning the surface of water bodies, such as water in swimming pools or swimming ponds, with an inlet channel in which a the extent of the water inlet regulating pivotable flap is arranged and which is connected to a container in which a sieve is ,

Es ist üblich, sogenannte Skimmer zur automatischen Reinigung der Oberfläche von Wasserkörpern einzusetzen. Skimmer bestehen im Wesentlichen aus einem Zulaufkanal mit Ansaugöffnung und einem beweglichen Wehr, welches sich der jeweiligen Wasserhöhe anpasst. Durch die Saugwirkung der vorgesehenen Filterpumpe strömt das Beckenwasser über das Wehr in den Skimmer, wobei hauptsächlich Wasser von der Wasseroberfläche abgesaugt und der Filteranlage zugeführt wird. Üblicherweise befindet sich im Skimmergehäuse ein Siebkorb, der grobe Verschmutzungen, wie Blätter und dergleichen, zurückhält und zur Reinigung entnommen werden kann.It is common to use so-called skimmers for automatic cleaning of the surface of water bodies. Essentially, skimmers consist of an inlet channel with a suction opening and a movable weir, which adapts to the respective water level. Due to the suction effect of the intended filter pump, the pool water flows through the weir into the skimmer, whereby mainly water is sucked from the water surface and fed to the filter system. Usually located in Skimmer housing a strainer, the coarse dirt, such as leaves and the like, withholds and can be removed for cleaning.

Es ist ferner bekannt, Bogensiebe bzw. Spaltsiebe zur Reinigung von Flüssigkeiten zu verwenden. Die zu reinigende Flüssigkeit fließt über das Bogensieb, welches eine relativ kleine Maschenweite aufweisen kann, sodass auch feine Verunreinigungen abgeschieden werden. Die Flüssigkeit fließt dabei im freien Gefälle von oben nach unten über das Sieb, sodass die zurückgehaltenen Verunreinigungen von der nachströmenden Flüssigkeit zum unteren Ende des Siebes gespült werden. Durch diesen selbstreinigenden Effekt muss das Sieb trotz des hohen Abscheidegrades nur selten gereinigt werden.It is also known to use bow screens or slot screens for the purification of liquids. The liquid to be cleaned flows over the curved screen, which may have a relatively small mesh size, so that even fine impurities are deposited. The liquid flows in free fall from top to bottom over the screen, so that the retained impurities are flushed by the inflowing liquid to the bottom of the screen. Due to this self-cleaning effect, the screen rarely needs to be cleaned, despite the high degree of separation.

Die selbstreinigende Funktion eines Bogensiebes ist nur dann gewährleistet, wenn die Flüssigkeit im freien Gefälle von oben nach unten fließen kann, das heißt, das Sieb selbst darf nicht in die Flüssigkeit eingestaut sein. Um das zu gewährleisten, wird das Wasser üblicherweise über ein starres Wehr und anschließend über das Bogensieb geleitet. Wird das Wasser, wie beispielsweise in Schwimmbecken, im Kreis geführt, muss nach dem Bogensieb ein Ausgleichsbehälter angeordnet werden, um den Wasserspiegel im Becken konstant zu halten und den kontinuierlichen Betrieb zu gewährleisten. Dies ist mit einem erheblichen Aufwand verbunden.The self-cleaning function of a curved screen is only guaranteed if the liquid can flow in free fall from top to bottom, that is, the sieve itself must not be jammed in the liquid. To ensure this, the water is usually passed over a rigid weir and then over the curved wire. If the water, as for example in swimming pools, led in a circle, a surge tank must be placed after the bow screen to keep the water level in the tank constant and to ensure continuous operation. This is associated with a considerable effort.

Um den Aufwand der Errichtung eines Ausgleichsbehälters bei der Verwendung eines Bogensiebes zu vermeiden, ist es aus der EP-A-1 593 305 bekannt, ein vertikal verschiebbares Wehr vorzusehen. Das Wehr ist mit einem Schwimmkörper verbunden, welcher unterhalb des Bogensiebes schwimmt. Damit wird sichergestellt, dass auch bei variabel zufließenden Wassermengen der Wasserstand unterhalb des Bogensiebes konstant gehalten wird. Die vertikale Verschiebbarkeit des Wehrs ist mit einer aufwendigen Konstruktion verbunden, indem das Wehr in schienenartigen Führungen geführt ist, welche in einer Behälterwand eingefräst sind. Ein Verklemmen des Wehrs und damit ein Stören der Funktion der gesamten Vorrichtung sind daher unvermeidbar. Problematisch ist auch ein Einlassen der bekannten Vorrichtung in den Boden, da die Gefahr besteht, dass die Schiebeführung für das Wehr auf seitlichen Druck, wie Erddruck, mit einer Blockade des Wehres reagiert.To avoid the expense of establishing a surge tank when using a curved screen, it is from the EP-A-1 593 305 known to provide a vertically displaceable weir. The weir is connected to a floating body, which floats below the curved sieve. This ensures that the water level below the curved sieve is kept constant, even with variably inflowing water quantities. The vertical displaceability of the weir is associated with a complex construction by the weir is guided in rail-like guides, which are milled in a container wall. A jamming of the weir and thus disrupting the function of the entire device are therefore unavoidable. Also problematic is an admission of the known device in the ground, since there is a risk that the sliding guide for the weir to lateral pressure, such as earth pressure, reacts with a blockage of the weir.

Der Erfindung liegt die Aufgabe zu Grunde, bei einer Vorrichtung der eingangs genannten Art auf konstruktiv einfache, dauerhaltbare und betriebssichere Weise eine sehr gute Reinigungswirkung des oberflächlichen Wassers von partikulären Verunreinigungen sicher zu stellen, wobei die Vorrichtung gegenüber Erddruck unempfindlich ausführbar sein soll.The invention is based on the object, in a device of the type mentioned in a structurally simple, durable and reliable way to ensure a very good cleaning effect of the superficial water of particulate impurities, the device should be insensitive to earth pressure executable.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass das im Behälter angeordnete Sieb ein Bogensieb ist.The object is achieved according to the invention characterized in that the arranged in the container sieve is a curved screen.

Die erfindungsgemäße Vorrichtung stellt durch die Kombination eines Skimmers einem Bogensieb auf eine konstruktiv sehr einfache Weise sicher, dass die Wasseroberfläche von partikulären Verunreinigungen optimal befreit werden kann. Die erfindungsgemäße Vorrichtung kann ferner in der Höhe des Wasserspiegels eingebaut werden.The device according to the invention by the combination of a skimmer ensures a curved screen in a structurally very simple manner that the water surface can be optimally freed from particulate impurities. The device according to the invention can also be installed at the height of the water level.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Klappe mit einem Schwimmkörper in Verbindung, welcher sich unterhalb des Bogensiebes befindet. Die erfindungsgemäße Vorrichtung stellt somit auf sehr einfache Weise sicher, dass der Wasserspiegel unterhalb des Bogensiebes bei variierenden Wassermengen konstant bleibt.According to a preferred embodiment of the invention, the flap is in communication with a floating body, which is located below the curved screen. The device according to the invention thus ensures in a very simple way that the water level below the curved screen remains constant with varying amounts of water.

Die Verbindung der Klappe mit dem Schwimmkörper lässt sich auf eine betriebsichere und zweckmäßige Weise mittels einer Stange ausführen, sodass etwaiger äußerer Druck auf den Behälter keine Auswirkungen auf die Funktion dieser Teile hat.The connection of the flap with the float can be carried out in a safe and convenient manner by means of a rod, so that any external pressure on the container has no effect on the function of these parts.

Bei einer bevorzugten Ausführungsform der Erfindung durchsetzt die Stange einen an einer Behälterwand befestigten Anschlagteil für den Schwimmkörper. Der Anschlagteil positioniert die Stange mit dem Schwimmkörper im Behälter ohne deren Funktion zu beeinträchtigen.In a preferred embodiment of the invention, the rod passes through a fixed to a container wall stop member for the float. The stop member positions the rod with the float in the container without affecting its function.

Der einfache, funktionssichere und zweckmäßige Aufbau der Vorrichtung wird ferner dadurch unterstützt, dass die Stange einen in den Behälter hineinragenden Teil des Zulaufkanals durchsetzt.The simple, reliable and functional design of the device is further supported by the fact that the rod passes through a projecting into the container part of the inlet channel.

Das untere Ende des Bogensiebes ist mit einer an einer Behälterwand befestigten Aufnahme verbunden ist, in welcher ein Korb oder dergleichen positionierbar ist. Die vom Sieb zurückgehaltenen Verunreinigungen sammeln sich daher in einem Korb, welcher zur Reinigung aus dem Behälter entfernt werden kann.The lower end of the curved screen is connected to a receptacle attached to a receptacle in which a basket or the like can be positioned. The debris retained by the sieve therefore collect in a basket which can be removed from the container for cleaning.

In der nachfolgenden Beschreibung beziehen sich die Begriffe oben, unten, horizontal und vertikal auf die Einbauposition der Vorrichtung.In the following description, the terms upper, lower, horizontal and vertical refer to the installation position of the device.

Die erfindungsgemäße Vorrichtung weist einen im Querschnitt rechteckigen Zulaufkanal 1 mit einer Frontöffnung 1a auf, welcher mit einem bei der dargestellten Ausführungsvariante quaderförmigen Behälter 3 fest verbunden ist. Der Behälter 3 weist daher einen Boden 3d, eine Vorderwand 3a, eine Rückwand 3b und zwei Seitenwände 3c auf, wobei der Zulaufkanal 1 an einem Ausschnitt am oberen Endbereich der Vorderwand 3a angeordnet ist und der Kanalboden 1 b mit einem Abschnitt 1'b über die Vorderwand 3a in das Innere des Behälters 3 geringfügig hineinragt. Am unteren Endbereich der Rückwand 3b befindet sich ein Ablaufrohr 8, welchem eine nicht gezeigte Pumpe nachgeordnet ist. Nicht dargestellt ist ferner eine den Behälter 3 von oben verschließbare Abdeckung. Der Behälter 3 wird mitsamt dem Zulaufkanal 1 in den Untergrund, die Erde, eingelassen.The inventive device has a rectangular cross-section inlet channel 1 with a front opening 1a, which is fixedly connected to a cuboidal container 3 in the illustrated embodiment. The container 3 therefore has a bottom 3d, a front wall 3a, a rear wall 3b and two side walls 3c, wherein the inlet channel 1 is arranged at a cutout at the upper end region of the front wall 3a and the channel bottom 1b with a portion 1'b over the Front wall 3 a protrudes slightly into the interior of the container 3. At the lower end of the rear wall 3b is a drain pipe 8, which is arranged downstream of a pump, not shown. Not shown is also a container 3 from the top closable cover. The container 3 is taken together with the inlet channel 1 in the ground, the earth.

Am Kanalboden 1 b ist nahe der Öffnung 1a eine Klappe 2 schwenkbar angelenkt. Im Ruhezustand liegt die Klappe 2 auf dem Kanalboden 1 b, ihr freies Ende überragt geringfügig den Kanalboden 1 b. Die Klappe 2 ist vom Kanalboden 1 b des Zulaufkanals 1 hochschwenkbar, derart, dass sie in ihrer am Weitesten hochgeschwenkten Lage unter einem spitzen Winkel zum Kanalboden verlaufend den Zulaufkanal 1 weitgehend verschließt, wie es in Fig. 1 zusätzlich mit durchgezogenen Linien angedeutet ist. Im Inneren des Behälters 3 befindet sich ein Bogensieb 4, welches zwischen dem überstehenden Abschnitt 1'b des Kanalbodens 1 b des Zulaufkanals 1 und einem im Querschnitt L-förmigen Aufnahmeteil 5 verläuft und an den Seitenwänden des Behälters 3 gelagert bzw. befestigt ist. Wie in Fig. 1 angedeutet ist, ist im Aufnahmeteil 5, welcher an der Rückwand 3b und den Seitenwänden 3c des Behälters 3 befestigt ist, von oben ein beispielsweise mit einem Bügel 15a oder dergleichen versehener Korb 15 einsetzbar. Im Korb 15 sammeln sich im Betrieb der Vorrichtung die abgeschiedenen Verunreinigungen, die derart aus der Vorrichtung entfernt werden können. Unterhalb des Bogensiebes 4 befindet sich im Behälter 3 nahe der Vorderwand 3a ein im Gehäuse 3 vertikal auf und ab bewegbarer Schwimmkörper 6, welcher mit einer Stange 7 fest verbunden ist, die vertikal und parallel zur Vorderwand 3a verlaufend bis zur Klappe 2 reicht, an deren Unterseite anliegt und derart die Klappe 2 abstützt. Die Stange 7 durchsetzt einen beispielsweise in Form einer Platte ausgeführten Anschlagteil 9 für den Schwimmkörper 6. Der Anschlagteil 9 ist mit der Vorderwand 3a des Behälters 3 fest verbunden ist. Die Stange 7 ist ferner durch eine Öffnung im Abschnitt 1'b des Kanalbodens 1 b des Zulaufkanals 1 geführt.At the bottom of the channel 1 b, a flap 2 is pivotally hinged near the opening 1a. In the resting state, the flap 2 is located on the channel bottom 1 b, their free end slightly surmounted the channel bottom 1 b. The flap 2 is swung up from the channel bottom 1 b of the inlet channel 1, such that it largely closes in its most highly pivoted position at an acute angle to the channel bottom extending the inlet channel 1, as in Fig. 1 additionally indicated by solid lines. Inside the container 3 is a curved screen 4, which extends between the protruding portion 1'b of the channel bottom 1 b of the inlet channel 1 and a cross-sectionally L-shaped receiving part 5 and is mounted or attached to the side walls of the container 3. As in Fig. 1 is indicated in the receiving part 5, which on the rear wall 3b and the Side walls 3 c of the container 3 is fixed, from the top, for example, provided with a bracket 15 a or the like basket 15 can be used. In the basket 15 accumulate during operation of the device, the deposited impurities that can be removed from the device in this way. Below the curved screen 4 is located in the container 3 near the front wall 3a in the housing 3 vertically up and down floating float 6, which is fixedly connected to a rod 7 which extends vertically and parallel to the front wall 3a extending to the flap 2, at the Underside and thus the flap 2 is supported. The rod 7 passes through an executed for example in the form of a plate stop member 9 for the float 6. The stop member 9 is fixedly connected to the front wall 3 a of the container 3. The rod 7 is further guided through an opening in the portion 1'b of the channel bottom 1 b of the inlet channel 1.

Im oberen Bereich des Behälters 3 erstreckt sich zwischen den oberen Seitenwänden 3c ein Leitwerk 10, welches sicherstellt, dass das Wasser von der Oberkante des Bogensiebs 4 herunterrinnt und nicht zu weit über das Sieb 4 stürzt.In the upper region of the container 3 extends between the upper side walls 3c, a tail 10, which ensures that the water from the upper edge of the Bogensiebs 4 down and not too far over the sieve 4 crashes.

Im Betrieb der Vorrichtung fließt Wasser durch den Zulaufkanal 1 über die Klappe 2 und schließlich über das Bogensieb 4. Das Bogensieb 4 kann eines der üblichen, metallischen Siebe mit einer Maschenweite von beispielsweise 0,2 mm bis 0,3 mm sein. Das über das Bogensieb 4 fließende Wasser wird von etwaigen festen Verunreinigungen befreit, die sich im Korb 15 sammeln. In dem unterhalb des Bogensiebes 4 im Behälter 3 befindlichen freien Volumen wird das Wasser gestaut. Der im gestauten Wasser schwimmende und mit der Klappe 2 in Wirkverbindung befindliche Schwimmkörper 6 stellt sicher, dass der Wasserspiegel unterhalb des Bogensiebes 4 auch bei variierenden Wassermengen konstant bleibt. Saugt beispielsweise die Pumpe mehr Wasser an, dann sinkt der Wasserspiegel, der Schwimmkörper 6 sinkt ebenfalls ab und die Klappe 2 öffnet sich mehr. Diese Position ist in Fig. 4 dargestellt. Wird die Pumpenleistung reduziert steigen der Wasserspiegel und der Schwimmkörper 6 und die zulaufende Wassermenge wird durch die sich hoch schwenkende Klappe 2 reduziert, wie es in Fig. 3 gezeigt ist.During operation of the device, water flows through the inlet channel 1 via the flap 2 and finally via the curved screen 4. The curved screen 4 can be one of the conventional, metallic screens with a mesh width of, for example, 0.2 mm to 0.3 mm. The water flowing through the curved screen 4 is freed of any solid impurities that collect in the basket 15. In the free volume located below the curved sieve 4 in the container 3, the water is jammed. The floating in the dammed water and with the flap 2 in operative connection float 6 ensures that the water level below the curved screen 4 remains constant even with varying amounts of water. For example, if the pump sucks more water, then the water level drops, the floating body 6 also drops and the flap 2 opens more. This position is in Fig. 4 shown. If the pump power is reduced, the water level and the float 6 increase and the incoming water quantity is reduced by the flap 2, which pivots upwards, as shown in FIG Fig. 3 is shown.

Die Konstruktion mit einem Schwimmkörper, welcher über ein Stange 7 die Klappe 2 betätigt, ist sehr betriebssicher, langlebig und neigt nicht zum Verklemmen. Die gesamte Anordnung aus Zulaufkanal und Behälter 3 kann auf einfache Weise sehr verwindungssteif ausgeführt werden, sodass sie im eingebauten Zustand dem Erddruck leicht standhalten kann.The construction with a float, which actuates the flap 2 via a rod 7, is very reliable, durable and does not tend to jamming. The Entire arrangement of inlet channel and container 3 can be performed in a simple way very rigid, so that they can easily withstand the earth pressure in the installed state.
