Description

Teichpumpe mit einstellbarem Ansaugvolumen Pond pump with adjustable suction volume
Die vorliegende Erfindung betrifft eine Teichpümpe mit einem Gehäuse, mit einem Ansauganschluß, dem ein mit Durchgangsschlitzen ausgebildeter Ansaugbereich einer Gehäuseschale zugeordnet ist, mit einem Druckanschluß, der über eine in dem Gehäuse angeordneten Pumpeinrichtung mit dem Ansauganschluß in Fluidkommu- nikation steht, mit einem Motor zum Antreiben der Pumpeinrichtung und mit einer Steuereinrichtung zum Steuern der Pumpeinrichtung und des Motors.The present invention relates to a pond pump with a housing, with a suction connection, to which a suction area of a housing shell formed with through slots is assigned, with a pressure connection, which is in fluid communication with the suction connection via a pump device arranged in the housing, with a motor for Driving the pump device and with a control device for controlling the pump device and the motor.
Solche Teichpumpen sind im Stand der Technik allgemein bekannt. Sie werden am Boden eines Teiches oder Beckens positioniert. Das Gehäuse der Teichpumpe ist als Grobfilter ausgebildet und weist Schlitze auf, durch die Wasser in das Gehäuse eindringen kann, nicht aber Blätter, kleine Zweige und andere gröbere Teilchen. Das Wasser wird durch eine im Gehäuse angeordnete Pumpenrichtung in einen hinter der Grobfilterschale liegenden Ansauganschluß gesaugt und über einen Druckanschluß in eine Druckleitung gedrückt, die das Wasser an einem freien Ende abgibt. In solchen Teichpumpen wird zur regelmäßigen Reinigung ausschließlich Wasser aus dem Bodenbereich des Teiches oder Beckens, angesaugt. Mit einer sol- chen Pumpe ist es nicht möglich, auch Wasser von der Teichoberfläche anzusaugen, um auch diese zu reinigen.Such pond pumps are generally known in the prior art. They are positioned on the bottom of a pond or basin. The housing of the pond pump is designed as a coarse filter and has slots through which water can penetrate the housing, but not leaves, small branches and other coarse particles. The water is sucked through a pump direction arranged in the housing into a suction connection lying behind the coarse filter bowl and is pressed via a pressure connection into a pressure line which releases the water at a free end. In such pond pumps, only water from the bottom area of the pond or basin is sucked in for regular cleaning. With such a pump it is not possible to draw water from the pond surface in order to clean it too.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Teichpumpe zu schaffen, mit der Wasser bei gegebenem Ansäugvolumen wahlfrei vom Bodenbe- reich. eines Teiches oder Beckens und/oder von der Wasseroberfläche desselben angesaugt werden kann. .The object of the present invention is to create a pond pump with which water can be freely selected from the floor area for a given suction volume. a pond or basin and / or from the surface of the water. ,
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Ansauganschluß zusätzlich ein Ansaugstutzen zugeordnet ist, der in Bezug zu dem Ansauganschluß verstellbar angeordnet ist, derart, dass ein Ansaugvolumen des Ansaugahschlusses auf den Ansaugstutzen und den Ansaugbereich aufteilbar ist. Mit der erfindüngsgemäßen Teichpumpe kann nunmehr über den Ansaugstutzen eine Ansaugleitung an der Teichpumpe angebracht werden, die im oberen Bereich • eines Wasserstandes endet, so dass aus diesem Bereich Wasser angesaugt werden kann, wobei das Ansaugvolumen des Ansauganschlusses bedarfsweise auf den Bodenbereich des Teiches und die Wasseroberfläche verteilt werden kann.The object is achieved according to the invention by additionally assigning an intake port to the intake port, which is arranged so as to be adjustable with respect to the intake port, in such a way that an intake volume of the intake port can be divided between the intake port and the intake area. With the erfindüngsgemäßen pond pump can now via the intake an intake passage on the pond pump mounted that • a water level ends at the top, can be so drawn out of this area of water, the suction volume of the suction port as required to the bottom region of the pond and the water surface can be distributed.
Ein weiterer Vorteil der vorliegenden Erfindung ist, dass der Ansaugstutzen zwischen einer ersten Endposition und einer zweiten Endposition verstellbar ist, wobei in der ersten Endposition der Anteil des Ansaugvolumens am Ansaugstutzen 100% und am Ansaugbereich 0% beträgt und in der zweiten Endposition der Anteil des Ansaugvolumens am Ansaugstutzen 0% und am Ansaugbereich 100% beträgt.Another advantage of the present invention is that the intake port is adjustable between a first end position and a second end position, the proportion of the intake volume in the intake port being 100% in the first end position and 0% in the intake area and the proportion of the intake volume in the second end position is 0% at the intake and 100% at the intake area.
Durch diese Einstellbarkeit des Ansaugvolumens ist es möglich, Wasser entweder nur von der Wasseroberfläche oder nur vom Bodenbereich anzusaugen oder aber das Ansaugvolumen zwischen diesen Extremstellungen aufzuteilen.This adjustability of the suction volume makes it possible to draw water either only from the water surface or only from the floor area or to divide the suction volume between these extreme positions.
Ein weiterer Vorteil besteht darin, dass der Ansaugstutzen und der Ansauganschluß mit einer Längsachse in einer Ebene angeordnet sind und der Ansaugstutzen um eine senkrecht zu der Längsachse stehende Drehachse zwischen der ersten Endposition und der zweiten Endpositon drehbar ist.Another advantage is that the intake port and the intake port are arranged in one plane with a longitudinal axis and the intake port is rotatable about an axis of rotation perpendicular to the longitudinal axis between the first end position and the second end position.
Durch diese Maßnahme kann die Teichpumpe in einer sehr kompakten Weise gebaut werden. Durch die Verdrehung des Ansaugstutzens läßt sich die Einstellung des Ansaugvolumens auch von außen optisch erkennen.With this measure, the pond pump can be built in a very compact manner. By turning the intake manifold, the setting of the intake volume can also be seen from the outside.
In diesem Zusammenhang ist ein weiterer Vorteil, dass die Längsachsen des Ansauganschlusses und des Ansaugstutzens .in der ersten Endposition zusammenfallen und in jeder anderen Position zwischen der ersten Endposition und der zweiten Endposition einen Winkel einschließen. Wenn der Druckanschlüß ebenfalls einen Druckstutzen zum Anschließen einer Druckleitung aufweist, was regelmäßig der Fall ist, verändert sich auch die Winkelposition zwischen dem Druckstύtzen und dem Ansaugstutzen um den Verstellwinkel. So dass die Einstellung auch aus der Entfernung optisch wahrnehmbar ist.In this context, another advantage is that the longitudinal axes of the intake port and the intake port . collapse in the first end position and enclose an angle in any other position between the first end position and the second end position. If the pressure connection also has a pressure connection for connecting a pressure line, which is regularly the case, the angular position between the pressure support and the intake connection also changes by the adjustment angle. So that the setting can be seen from a distance.
Weitere Vorteile ergeben sich aus den Merkmalen der weiteren Unteransprüche.Further advantages result from the features of the further subclaims.

Fig. 7 eine schematische Schnittansicht durch einen typischen Gartenteich, mit der bodenseitig aufgestellten erfindungsgemäßen Teichpumpe, zur Darstellung der zwei örtlich entfernten Ansaugstellen am Teichboden und an der Wasseroberfläche.Fig. 7 is a schematic sectional view through a typical garden pond, with the pond pump according to the invention set up on the bottom, to show the two locally removed suction points on the pond bottom and on the water surface.
In Fig. 1 ist schematisch eine Teichpumpe 1 dargestellt. Die Teichpumpe 1 weist ein Gehäuse 3 auf, dessen obere Gehäuseschale als Filterdeckel 3.1 ausgebildet ist. Der Filterdeckel 3.1 weist kleine Öffnungen oder Schlitze 3.2 auf, die als Grobfilter dienen. Aus dem Umfang des Gehäuses 3 stehen ein Druckstutzen 5 und ein Ansaugstutzen 7 vor.In Fig. 1, a pond pump 1 is shown schematically. The pond pump 1 has a housing 3, the upper housing shell of which is designed as a filter cover 3.1. The filter cover 3.1 has small openings or slots 3.2, which serve as a coarse filter. From the circumference of the housing 3, a pressure port 5 and an intake port 7 protrude.
In Fig. 2 ist die Teichpumpe aus Fig. 1 ohne Filterdeckel 3.1 dargestellt. Im Inneren des Gehäuses 3 ist eine Pumpeinrichtung 9 angeordnet, die von üblicher Bauart ist und hier nicht weiter beschrieben wird. Im hinteren Teil der unteren Hälfte des Gehäuses 3, der sogenannten Unterschale, sind ebenfalls kleine Öffnungen oder Schlitze 3.2 als Grobfilter ausgebildet. Durch diese Öffnungen oder kleinen Schlitze 3.2 kann auch Wasser aus einem Teich angesaugt werden, so dass diese Öffnungen und kleinen Schlitze 3.2 an dem Gehäuse 3 einen Ansaugbereich bilden, der im Folgenden als Synonym auch das Bezugszeichen 3.2 zugewiesen bekommt. Hinter der Pumpeinrichtung 9 ist ein Elektromotor 11 wasserdicht angeordnet.In Fig. 2 the pond pump from Fig. 1 is shown without filter cover 3.1. In the interior of the housing 3, a pump device 9 is arranged, which is of conventional design and is not described further here. In the rear part of the lower half of the housing 3, the so-called lower shell, small openings or slots 3.2 are also formed as coarse filters. Through these openings or small slots 3.2, water can also be sucked out of a pond, so that these openings and small slots 3.2 form a suction area on the housing 3, which in the following is also assigned the reference symbol 3.2 as a synonym. An electric motor 11 is arranged watertight behind the pump device 9.
In Fig. 3 ist schematisch eine Draufsicht der Teichpumpe 1 ohne Filterdeckel 3.1 dargestellt. In dem Gehäuse 3 ist in Fluidkommunikation mit der Pumpeinrichtung 9 ein Ansauganschluß 17 ausgebildet. In einem Winkel zu dem Ansauganschluß 17, vorzugsweise senkrecht zu dem Ansauganschluß 17, ist ein Druckanschluß 15 mit dem Druckstutzen 5 ausgebildet. Der Ansauganschluß 17 und der Druckanschluß 15 weisen jeweils eine Längsachse auf, die in der vorliegenden Ausführungsform in einer gemeinsamen Ebene liegen. In einer Betriebsposition der Teichpumpe 1 ist diese gemeinsame Ebene vorzugsweise eine horizontale Ebene. In anderen Ausfüh- rungsformen kann diese Ebene aber auch eine in Betriebsposition vertikale Ebene oder eine Ebene zwischen einer horizontalen und einer vertikalen Ebene Sein. Es ist auch denkbar, dass die beiden Längsachsen des AnsaugänsChlüsses 17 und des Druckanschlusses 15 nicht in einer gemeinsamen Ebene liegen.In Fig. 3, a top view of the pond pump 1 without filter cover 3.1 is shown schematically. An intake port 17 is formed in the housing 3 in fluid communication with the pump device 9. A pressure connection 15 with the pressure connection 5 is formed at an angle to the suction connection 17, preferably perpendicular to the suction connection 17. The suction connection 17 and the pressure connection 15 each have a longitudinal axis which lie in a common plane in the present embodiment. In an operating position of the pond pump 1, this common plane is preferably a horizontal plane. In other versions However, this level can also be a vertical level in the operating position or a level between a horizontal and a vertical level. It is also conceivable that the two longitudinal axes of the intake wrench 17 and the pressure connection 15 are not in a common plane.
Der Ansaugstutzen 7 ist in Bezug zu dem Ansauganschluß 17 verstellbar in dem Gehäuse 3 angeordnet. In Fig. 3 befindet sich der Ansaugstutzen 7 in einer zweiten Endposition, welche den Ansaugstutzen 7 aus einer Fluidkommunikation mit dem Ansauganschlüß 17 bringt. Es besteht also keine Fluidverbindung zwischen dem Ansaugstutzen 7 und dem Anschluß 17. In dieser Position saugt der Ansauganschluß 17 100% seines Ansaugvolumens durch den Ansaugbereich bzw. die Schlitze 3.2 des Filterdeckels 3.1 bzw. der Unterschale an. Der Ansaugstutzen 7 kann stü- fenlos oder über Zwischenstellungen in die in Fig. 4 dargestellte Endposition gebracht werden. In der in Fig. 4 dargestellten Endposition saugt die Pumpeinrichtung 9 100% des Ansaugvolumens über den Aήsauganschluß 17 und den Druckstutzen 7 an. In dieser ersten Endposition in Fig. 4 wird kein Wasser durch den Ansaugbereich 3.2 angesaugt.The intake port 7 is arranged adjustable in the housing 3 with respect to the intake port 17. In FIG. 3, the intake port 7 is in a second end position, which brings the intake port 7 out of fluid communication with the intake port 17. There is therefore no fluid connection between the suction nozzle 7 and the connection 17. In this position, the suction connection 17 sucks 100% of its suction volume through the suction area or the slots 3.2 of the filter cover 3.1 or the lower shell. The intake manifold 7 can be brought into the end position shown in FIG. 4 continuously or via intermediate positions. In the end position shown in FIG. 4, the pump device 9 sucks 100% of the suction volume via the suction connection 17 and the pressure port 7. In this first end position in FIG. 4, no water is drawn in through the suction area 3.2.
In Fig. 3 und Fig. 4 ist dargestellt, daß der Ansaugstutzen 7 auf einer Kreisbahn um eine Drehachse drehbar ist, die senkrecht auf der Längsachse des Ansaugstutzens 7 steht. Mit der Verstellung des Ansaugstutzeiis 7 in eine wahlfreie Zwischenstellung zwischen der ersten Endposition in Fig. 4 und der zweiten Endposition in Fig. 3 kann das Ansaugvolumen der Pumpeinrichtung 9 auf den Ansaugstutzen 7 und auf die Schlitze 3.2 des Filterdeckels 3.1 verteilt werden.In Fig. 3 and Fig. 4 it is shown that the intake manifold 7 is rotatable on a circular path about an axis of rotation which is perpendicular to the longitudinal axis of the intake manifold 7. With the adjustment of the suction nozzle egg 7 into an optional intermediate position between the first end position in FIG. 4 and the second end position in FIG. 3, the suction volume of the pump device 9 can be distributed over the suction nozzle 7 and over the slots 3.2 of the filter cover 3.1.
Durch die wahlfreie Positionierung des Ansaugstutzens 7 in Bezug zum Ansauganschluß.17 kan das Ansaugvolumen der Pumpeinrichtung 9 über den Ansaugstutzen zwischen 0% und 100% eingestellt werden. Die jeweilige Differenz des Ansaugvolumens auf 100% wird dann über den Ansaugbereich 3.2 geliefert. In Fig. 5 ist die erfindungsgemäße Teichpumpe schematisch und perspektivisch von der Seite aus zu sehen. Auf der rechten Seite in Fig. 5 sind die Ansaugschlitze 3.2 bzw. der von diesen gebildete Ansaugbereich 3.2 dargestellt. In Fig. 6 ist eine Draufsicht der Teichpumpe 1 aus Fig. 5 dargestellt. Die Draufsicht aus Fig. 6 ist etwas detaillierter als die Draufsichten aus Fig. 3 und Fig. 4. Der Ansaugstutzen 7 kann auch stufenweise verstellbar sein. Dafür sind in Fig. 6 Rastpunkte 19 ausgebildet, an denen der Ansaugstutzen 7 positioniert werden kann. Der Ansaugstutzen 7 weist ein Gewinde 21, vorzugsweise ein Außengewinde, auf, an dem eine Säugleitung angeschlossen werden kann. Die Pύmpeinrichtung kann mit einer Frostschutzeinrichtung (nicht dargestellt) versehen sein, die sie vor einem Einfrieren schützt. Auch der Druckstύtzen 5 weist ein Gewinde 23 auf, vorzugsweise auch ein Außengewinde, an dem eine Druckleitung (nicht dargestellt) angeschlos^ sen werden kann. In dem Gehäuse 3 ist auch ein Kabelanschluß 25 für eine elektri- sehe Zuleitung vorgesehen.Through the optional positioning of the intake port 7 in relation to the intake port 17, the intake volume of the pump device 9 can be set between 0% and 100% via the intake port. The respective difference in the intake volume to 100% is then supplied via the intake area 3.2. 5, the pond pump according to the invention can be seen schematically and in perspective from the side. On the right side in FIG. 5, the suction slots 3.2 or the suction area 3.2 formed by them are shown. FIG. 6 shows a top view of the pond pump 1 from FIG. 5. The top view from FIG. 6 is somewhat more detailed than the top views from FIGS. 3 and 4. The intake manifold 7 can also be adjustable in steps. For this purpose, locking points 19 are formed in FIG. 6, at which the intake port 7 can be positioned. The suction nozzle 7 has a thread 21, preferably an external thread, to which a nursing line can be connected. The pumping device can be provided with an anti-freeze device (not shown) which protects it from freezing. Can also be the Druckstύtzen 5 comprises a thread 23, also preferably an external thread (not shown) to which a pressure line is Schlos sen ^ are. In the housing 3 there is also a cable connection 25 for an electrical feed line.
Der von dem Ansaügstutzen 7 und dem Druckstutzen 5 eingeschlossene Winkel beträgt in der ersten Endposition, das heißt, bei 100% Ansaugleistung durch den Ansaugstutzen 7, 90°. Der Winkel zwischen dem Druckstützen 5 und dem Ansaug- stutzen 7 in der zweiten Endposition beträgt zwischen etwa 90° und 180°. Der Winkel des Ansaugstutzens 7 in Bezug zur Längsachse des Ansauganschlusses 17 beträgt in der ersten Endposition 0° und in der zweiten Endposition etwa 0 bis 90°.The angle enclosed by the intake nozzle 7 and the pressure connector 5 is 90 ° in the first end position, that is, at 100% suction power through the intake connector 7. The angle between the pressure supports 5 and the intake manifold 7 in the second end position is between approximately 90 ° and 180 °. The angle of the intake port 7 with respect to the longitudinal axis of the intake port 17 is 0 ° in the first end position and approximately 0 to 90 ° in the second end position.
In Fig. 7 ist eine Systemskizze dargestellt, die einen Teichquerschnitt zeigt. Am Boden des dargestellten Teiches ist die erfindungsgemäße Teichpumpe 1 positioniert. An dem Druckstutzeή 5 ist eine Druckleitung 35 angebracht; die zu eine Teichfilter außerhalb des Teiches führt. An dem Ansaugstutzen 7 ist eine Ansaugleitung 37 angebracht, die zu einem Skimmer 47 im Bereich der Wasseroberfläche des Teiches führt. Je nach Positionierung des Ansaugstutzens 7 in Bezug zum An- säuganschluß 17 kann die Ansaugung von Bodenschmutz wahlweise zwischen 0 und 100% der gesamten Pumpenleistung variiert werden. Entsprechend kann die Ansaugung von Oberflächenschmutz wahlweise zwischen 0 und 100% variiert werden. So ist es z.B. möglich, über eine Zwischenpositionierung des Ansaugstutzens 7 in Bezug zum Anschluß 17 70% der gesamten Pumpenleistung auf den Ansaugbereich 3.2 zu richten und entsprechend Bodenschmutz anzusaugen und 30% der gesamten Pumpenleistung auf den Ansaugstutzen 7 zu richten und entsprechend Oberflächenschmutz anzusaugen. 7 shows a system sketch which shows a pond cross section. The pond pump 1 according to the invention is positioned at the bottom of the pond shown. A pressure line 35 is attached to the pressure port 5; which leads to a pond filter outside the pond. A suction line 37 is attached to the suction nozzle 7 and leads to a skimmer 47 in the area of the water surface of the pond. Depending on the positioning of the suction nozzle 7 in relation to the suction connection 17, the suction of soil dirt can optionally be varied between 0 and 100% of the total pump output. Accordingly, the Suction of surface dirt can be varied between 0 and 100%. So it is possible, for example, to position 70% of the total pump capacity at the suction area 3.2 by means of an intermediate positioning of the suction nozzle 7 in relation to the connection 17 and to suck in dirt in accordance with the soil and to direct 30% of the total pump capacity onto the suction nozzle 7 and to suck in the surface dirt accordingly.
