A swivel arm (6) which can swivel about a perpendicular axis bears a vertically movable brush carrier (13) on which a drivable brush (17) is mounted. Perpendicular guide rods (18) attached to the brush carrier (13) are guided in guides (19) on the swivel arm (6). Two guiding rod chains (28), which each consist of two guiding rods (26, 27) connected to one another in articulated fashion, connect the brush carrier (13) to the swivel arm (6) and support the lateral guidance of the brush carrier (13) so that a narrow design is made possible. <IMAGE>

Description

Die Erfindung betrifft ein Waschgerät für Ablaufrinnen von Nachklärbecken in Kläranlagen mit einem Bürstenträger, der einen Antriebsmotor und eine Lagerung einer senkrechten Bürste aufweist, mit einem längs der Ablaufrinne bewegbaren Geräteträger, der den Bürstenträger seitlich schwenkbar und höhenverstellbar trägt, mit einem Seilzug zum Gewichtsausgleich für den Bürstenträger und mit am Bürstenträger angreifenden Lenkern mit waagerechten Gelenkachsen.The invention relates to a washing device for gutters of secondary settling tanks in sewage treatment plants with a brush holder, which has a drive motor and a vertical brush bearing, with a device holder movable along the gutter, which supports the brush holder laterally pivotable and adjustable in height, with a cable for weight compensation for the Brush holder and with handlebars with horizontal joint axes acting on the brush holder.

Derartige Waschgeräte dienen dazu, die Ablaufrinnen von biologischen Nachklärbecken in Kläranlagen zu säubern. In den Ablaufrinnen bildet sich sehr rasch ein Algenbewuchs, der laufend entfernt werden muß. Da der Rinnenboden nicht vollständig eben ist und in vielen Fällen sogar ein Gefälle aufweist, muß eine Höhenbeweglichkeit der Bürste gegenüber dem Geräteträger vorgesehen sein. Die seitliche Verstellbarkeit der Bürste ist erforderlich, um die Bürste wahlweise an der rechten oder linken Seitenwand der Ablaufrinne zur Anlage zu bringen.Such washing devices are used to clean the drainage channels of biological secondary settling tanks in sewage treatment plants. Algae growth forms very quickly in the drainage channels and must be removed continuously. Since the channel floor is not completely flat and in many cases even has a slope, the height of the brush relative to the equipment carrier must be provided. The lateral adjustability of the brush is necessary in order to bring the brush against the right or left side wall of the drainage channel.

Bei einem bekannten Waschgerät der eingangs genannten Gattung (DE-A-33 14 987) ist der Bürstenträger an zwei übereinander angeordneten Lenkern angebracht, die ein Lenkerparallelogramm bilden und die höhenbewegliche Führung des Bürstenträgers übernehmen. Diese Parallellenker sind an einer Schwenksäule gelagert, die um eine senkrechte Achse am Geräteträger schwenkbar ist, um die Bürste seitlich zu verstellen, um sie wahlweise an der rechten oder linken Seitenwand der Ablaufrinne zur Anlage zu bringen.In a known washing machine of the type mentioned at the beginning (DE-A-33 14 987), the brush holder is attached to two handlebars arranged one above the other, which form a handlebar parallelogram and take over the vertically movable guidance of the brush holder. These parallel links are mounted on a swivel column, which can be swiveled around a vertical axis on the equipment carrier, in order to adjust the brush sideways so that it can be brought into contact either on the right or left side wall of the drainage channel.

Die Höhenbeweglichkeit und die seitliche Verstellbarkeit der Bürste sind durch die Abmessungen der Lenker begrenzt. Werden die Lenker verhältnismäßig lang ausgeführt, so verringert sich die Führungsgenauigkeit vor allem in der tiefsten Stellung der Bürste, weil das Lenkerparallelogramm dann weitgehend gestreckt ist. Dies gilt vor allem bei verhältnismäßig schmaler Bauweise des Waschgeräts, die bei schmalen, tiefen Ablaufrinnen geboten ist.The height mobility and the lateral adjustability of the brush are limited by the dimensions of the handlebars. If the handlebars are made relatively long, the guidance accuracy is reduced, especially in the lowest position of the brush, because the handlebar parallelogram is then largely stretched. This applies especially to the relatively narrow design of the washing machine, which is required for narrow, deep drainage channels.

Aufgabe der Erfindung ist es daher, ein Waschgerät der eingangs genannten Gattung zu schaffen, das bei einfachem Aufbau und schmaler Bauweise ohne Beeinträchtigung der Führungsgenauigkeit einen verhältnismäßig großen Höhenverstellhub ermöglicht.The object of the invention is therefore to provide a washing device of the type mentioned, which allows a relatively large height adjustment stroke with a simple structure and narrow construction without impairing the accuracy of guidance.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Geräteträger ein Schwenkarm mit senkrechter Schwenkachse gelagert ist, daß am Schwenkarm mindestens eine Führung für eine am Bürstenträger befestigte senkrechte Führungsstange angebracht ist, und daß der Schwenkarm und der Bürstenträger über mindestens eine Lenkerkette miteinander verbunden sind, die aus zwei Lenkern besteht, die miteinander und mit dem Schwenkarm und dem Bürstenträger jeweils in einer waagerechten Gelenkachse verbunden und in der senkrechten Ebene des Schwenkarms auslenkbar sind.This object is achieved in that a swivel arm with a vertical swivel axis is mounted on the equipment carrier, that at least one guide for a vertical guide rod fastened to the brush holder is attached to the swivel arm, and that the swivel arm and the brush holder are connected to one another via at least one link chain, which consists of two links, which are connected to each other and to the swivel arm and the brush holder in a horizontal hinge axis and can be deflected in the vertical plane of the swivel arm.

Die Höhenführung des Bürstenträgers wird hierbei von der Führungsstange übernommen, wobei bevorzugterweise zwei senkrechte Führungsstangen am Bürstenträger befestigt sind, die in zwei Führungen am Schwenkarm geführt sind und die in Längsrichtung des Schwenkarms im Abstand zueinander angeordnet sind.The height of the brush holder is taken over by the guide rod, preferably two vertical guide rods are attached to the brush holder, which are guided in two guides on the swivel arm and which are arranged at a distance from one another in the longitudinal direction of the swivel arm.

Der Höhenverstellhub wird hierbei nur durch die Länge der Führungsstangen bestimmt. Die Versteifung gegen eine seitliche Auslenkung (d.h. senkrecht zu der den Schwenkarm enthaltenden senkrechten Ebene) wird durch die Lenkerkette übernommen, wobei vorzugsweise ebenfalls zwei Lenkerketten vorgesehen sind.The height adjustment stroke is only determined by the length of the guide rods. The stiffening against lateral deflection (i.e. perpendicular to the vertical plane containing the swivel arm) is taken over by the link chain, two link chains preferably also being provided.

Obwohl die Breite der Lenkerketten senkrecht zur Ebene des Schwenkarms nur gering ist, so daß eine sehr schmale Bauweise ermöglicht wird, bewirken die Lenkerketten doch eine stabile Abstützung gegenüber Seitenkräften, die quer zu dieser Ebene wirken.Although the width of the link chains perpendicular to the level of the swivel arm is only small, so that a very narrow construction is possible, the link chains nevertheless provide stable support against lateral forces which act transversely to this level.

Da die Lenkerketten eine um so stabilere Abstützung gegenüber Seitenkräften bewirken, je mehr die Lenkerketten gestreckt sind, wird diese seitliche Versteifung gerade dann verstärkt, wenn die Stabilität der seitlichen Führung durch die Führungsstangen geringer wird, nämlich bei sehr weit abgesenktem Bürstenträger.Since the handlebar chains provide a more stable support against lateral forces, the more the handlebar chains are stretched, this lateral stiffening is only increased when the stability of the lateral guidance by the guide rods is reduced, namely when the brush holder is lowered very far.

Das Waschgerät ist von verhältnismäßig einfachem Aufbau, weil keine senkrechte Führungssäule benötigt wird und weil der Seilzug für den Gewichtsausgleich am Schwenkarm gelagert ist.The washing machine is of relatively simple construction because no vertical guide column is required and because the cable is mounted on the swivel arm for weight compensation.

In einer besonders stabilen, dabei aber sehr einfachen Ausführungsform des Waschgerätes bestehen die Lenker jeweils aus zwei parallelen, starr miteinander im Abstand verbundenen Lenkerholmen. Vorzugsweise ist jeder Lenkerholm eines Lenkers jeweils über ein gesondertes Gelenk mit dem zugeordneten Lenkerholm des anderen Lenkers bzw. mit dem Schwenkarm bzw. mit dem Bürstenträger verbunden. Hierbei reichen konstruktiv sehr einfache Gelenke aus, um eine hohe Abstützwirkung zu erbringen.In a particularly stable, but very simple embodiment of the washing device, the handlebars each consist of two parallel handlebars rigidly connected to one another at a distance. Each handlebar of a handlebar is preferably connected via a separate joint to the associated handlebar of the other handlebar or to the swivel arm or to the brush holder. In this case, very simple joints are sufficient to provide a high support effect.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments of the inventive concept are the subject of further dependent claims.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

  • Fig. 1 ein Waschgerät für Ablaufrinnen von Nachklärbekken in Kläranlagen in einer Seitenansicht und teilweise im Schnitt und
  • Fig. 2 eine Ansicht des Waschgerätes nach Fig. 1 in Richtung des Pfeiles II.
The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawing. It shows:
  • Fig. 1 is a washing device for troughs of secondary clarification tanks in sewage treatment plants in a side view and partially in section and
  • Fig. 2 is a view of the washing machine of FIG. 1 in the direction of arrow II.

Das dargestellte Waschgerät 1 ist an einem nur teilweise gezeigten Räumerarm oder einer Räumerbrücke 2 eines biologischen Nachklärbeckens in einer Kläranlage angebracht. Ein Geräteträger 3, der im wesentlichen aus einem schmalen senkrechten Rahmen besteht, ist an der Räumerbrücke 2 angeschraubt. Zwei übereinander am Geräteträger 3 befestigte Konsolen 4 tragen eine Lagerung 5 mit senkrechter Schwenkachse, in der ein Schwenkarm 6 gelagert ist.The washing device 1 shown is attached to a scraper arm or a scraper bridge 2 of a biological secondary clarifier, which is only partially shown, in a sewage treatment plant. An equipment carrier 3, which consists essentially of a narrow vertical frame, is screwed onto the scraper bridge 2. Two consoles 4 fastened one above the other on the equipment carrier 3 carry a bearing 5 with a vertical swivel axis, in which a swivel arm 6 is mounted.

Eine auf dem Schwenkarm 6 befestigte, nach oben ragende Stütze 7 ist an ihrem oberen Ende mit einem Querarm 8 verbunden, an dessen beiden Enden jeweils ein Seilzug 9 angreift. Beide Seilzüge 9 können wahlweise mit einem Gewicht 10 belastet werden und sind über Umlenkrollen 11 geführt, die ortsfest an einem mit der Räumerbrücke 2 verbundenen Träger 12 gelagert sind. Je nach dem, welcher der beiden Seilzüge 9 mit dem Gewicht 10 belastet wird, wird der Schwenkarm 6 wahlweise nach einer von beiden Seiten mittels Gewichtskraft ausgelenkt.A support 7, which is attached to the swivel arm 6 and projects upwards, is connected at its upper end to a cross arm 8, on each end of which a cable 9 engages. Both cables 9 can optionally be loaded with a weight 10 and are guided over deflection rollers 11, which are fixed in position on a carrier 12 connected to the scraper bridge 2. Depending on which of the two cables 9 is loaded with the weight 10, the swivel arm 6 is optionally deflected to either side by means of weight.

Ein Bürstenträger 13, der einen Antriebsmotor 14 und eine Lagerung 15 für eine senkrechte Bürstenwelle 16 trägt, auf der eine Bürste 17 angebracht ist, ist mit zwei senkrecht nach oben ragenden Führungestangen 18 fest verbunden. Die beiden Führungsstangen 18 sind jeweils in einer Führung 19 geführt, die beispielsweise als Führungsbuchse ausgebildet ist und die am Schwenkarm 6 angebracht ist. Mittels dieser Führungen 19 kann der Bürstenträger 13 eine senkrechte Bewegung ausführen, die erforderlich ist, damit die Bürste 17 einem ansteigenden Verlauf eines Rinnenbodens 20 folgen kann. Außerdem kann die Bürste 17 vom Rinnenboden 20 angehoben werden, wenn dies erforderlich ist.A brush holder 13, which carries a drive motor 14 and a bearing 15 for a vertical brush shaft 16, on which a brush 17 is attached, is fixedly connected to two guide rods 18 projecting vertically upwards. The two guide rods 18 are each guided in a guide 19 which is designed, for example, as a guide bush and which is attached to the swivel arm 6. By means of these guides 19, the brush holder 13 can perform a vertical movement, which is required is so that the brush 17 can follow an increasing course of a channel bottom 20. In addition, the brush 17 can be raised from the channel bottom 20 if this is necessary.

Zum Gewichtsausgleich ist der Bürstenträger 13 über zwei Seilzüge 21 über am Schwenkarm 6 gelagerte Umlenkrollen 22 mit einem Ausgleichsgewicht 23 verbunden, das an einer senkrechten Führungsschiene 24 geführt ist, die mit dem Geräteträger 3 starr verbunden ist.To balance the weight, the brush holder 13 is connected via two cables 21 via deflection rollers 22 mounted on the swivel arm 6 to a counterweight 23 which is guided on a vertical guide rail 24 which is rigidly connected to the device holder 3.

An einem Tragteil 25 des Schwenkarmes 6, das auch die Führungen 19 aufnimmt, sind beiderseits der Führungsstangen 18 zwei Lenker 26 angelenkt, die jeweils mit einem weiteren Lenker 27 gelenkig verbunden sind, der wiederum gelenkig mit dem Bürstenträger 13 verbunden ist.On a support part 25 of the swivel arm 6, which also receives the guides 19, two links 26 are articulated on both sides of the guide rods 18, each of which is articulated to a further link 27, which in turn is articulated to the brush holder 13.

Jeweils ein Lenker 26 und ein Lenker 27 bilden eine Lenkerkette 28, die in der senkrechten Ebene des Schwenkarmes 6 auslenkbar ist. Wie man in der Seitenansicht nach Fig. 1 erkennt, bilden die beiden Lenkerketten 28, der Bürstenträger 13 und der Abschnitt 25 des Schwenkarmes 6 ein Sechseck.In each case a link 26 and a link 27 form a link chain 28 which can be deflected in the vertical plane of the swivel arm 6. As can be seen in the side view according to FIG. 1, the two link chains 28, the brush holder 13 and the section 25 of the swivel arm 6 form a hexagon.

Aus Fig. 2 erkennt man, daß die Lenker 26, 27 jeweils aus zwei parallelen Lenkerholmen 26a, 26b bzw. 27a, 27b bestehen, die jeweils starr miteinander im Abstand durch Stege 26c bzw. 27c verbunden sind. Die waagerechten Gelenkachsen der Lenker 26, 27 werden durch einzelne Gelenke 29 gebildet, die die Lenker 26, 27 der Lenkerketten 28 miteinander und mit dem Schwenkarm 6 bzw. dem Bürstenträger 13 verbinden.From Fig. 2 it can be seen that the links 26, 27 each consist of two parallel handlebars 26a, 26b and 27a, 27b, which are each rigidly connected to one another at a distance by webs 26c and 27c. The horizontal hinge axes of the links 26, 27 are formed by individual joints 29 which connect the links 26, 27 of the link chains 28 to one another and to the swivel arm 6 or the brush holder 13.

In Fig. 2 ist gezeigt, daß die Konstruktion auch so ausgeführt werden kann, daß insgesamt vier Führungsstangen 18 vorgesehen sind, die in vier Führungen 19 am Schwenkarm 6 senkrecht beweglich geführt sind.In Fig. 2 it is shown that the construction can also be carried out so that a total of four guide rods 18 are provided which are guided in four guides 19 on the swivel arm 6 vertically movable.
