Description
Die Erfindung betrifft eine Leckwarneinrichtung für FlUssigkeitstanks mit Auffangwannen.The invention relates to a leak warning device for liquid tanks with collecting trays.
In Industrieanlagen,in denen wassergefährdende Flüssigkeiten gelagert werden müssen, bedarf es, diese Flüssigkeitstanks in sogenannten Auffangwannen zu stationieren.In industrial plants where water-polluting liquids have to be stored, these liquid tanks must be stationed in so-called collecting trays.
Eine Leckage an einem Tank führt dazu, daß die auslaufende Flüssigkeit dann zunächst in diese Auffangwanne einläuft. Wird der Schaden an einem dieser FlUssigkeitstanks jedoch nicht rechtzeitig erkannt, so kann die Flüssigkeit auch aus den überfüllten Auffangwannen auslaufen.A leak in a tank means that the escaping liquid initially flows into this collecting tray. However, if the damage to one of these liquid tanks is not detected in time, the liquid can also leak from the overfilled collecting trays.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Leckwarneinrichtung bereitzustellen, die an verschiedenen Behältern bzw. Auffangwannen montierbar ist und auf die individuelle Flüssigkeitshöhen einstellbar und mit einer Warneinrichtung koppelbar ist.The invention is therefore based on the object of providing a leak warning device that can be mounted on various containers or collecting trays and can be adjusted to the individual liquid levels and coupled to a warning device.
Das Funktionsprinzip basiert auf mindestens einer,an einem FUuergehäuse angeordneten Meßelektrode ,die bei leitfähigen Flüssigkeiten konduktiv bzw. bei nicht leitfähigen Flüssigkeiten kapazitiv arbeitet bzw. arbeiten.The functional principle is based on at least one measuring electrode arranged on a fuel housing, which works conductively with conductive liquids or capacitively with non-conductive liquids.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, iaß die Leckwarneinrichtung für Flüssigkeitstanks mit Auffangwannen mit einem in einen Behälterraum ragendes Fühlergehäuse versehen ist, das dadurch gekennzeichnet | ist, daß das Fühlergehäuse mindestens eine Elektrode aufweist, die als Meßfühler bzw. Bezugselektrode fungiert bzw. fungieren.This object is achieved according to the invention in that the leak warning device for liquid tanks with collecting trays is provided with a sensor housing that protrudes into a container space, which is characterized in that the sensor housing has at least one electrode that functions as a measuring sensor or reference electrode.

Eine besonders bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß das Fühlergehäuse mittels Stell-Verschraubfjng höhenverstell- und feststellbar ist.A particularly preferred embodiment is characterized in that the sensor housing can be adjusted in height and locked by means of an adjusting screw.
Eine weitere besonders bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß diese einen Anschlagwinkel mit mindestens zwei Bohrungen aufweist, der zur Befestigung an der Behälterwand dient.Another particularly preferred embodiment is characterized in that it has a stop angle with at least two holes, which serves for fastening to the container wall.
Eine weitere bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß ein aus dem Fühlergehäuse herausführender Kabelkanal durch eine Stellverschraubung führt, mit deren Stopfbuchsen die Einstellhöhe bzw. Ansprechhöhe der Meßfühler einstellbar ist.A further preferred embodiment is characterized in that a cable duct leading out of the sensor housing leads through an adjusting screw connection, with the glands of which the setting height or response height of the measuring sensors can be adjusted.
Eine weitere besonders bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß der Anschlagwinkel auf seiner Kopfseite einen Anschlußkopf aufweist, an dem seitlich eine Kabelklemmvorrichtung angeordnet ist, an der ein Kabel angeschlossen wird.Another particularly preferred embodiment is characterized in that the stop angle has a connection head on its head side, on the side of which a cable clamping device is arranged, to which a cable is connected.
Anhand der beigefügten Zeichnungen, die ein besonders bevorzugtes Ausführungsbeispiel der Erfindung zeigen,
wird diese nun näher erläutert.
Dabei zeigen:The invention will now be explained in more detail with reference to the accompanying drawings, which show a particularly preferred embodiment.
Showing:
Figur 1 eine Gesamtheit der erfindungsgemäßen Leckwarneinrichtung;Figure 1 shows an entire leak warning device according to the invention;
Figur 2 eine Ansicht des Anschlagwinkels aus der in Figur 1 angedeuteten Richtung A.Figure 2 is a view of the stop angle from the direction A indicated in Figure 1.

Figur 1 zeigt die Gesamtheit der erfindungsgemäßen Leckwarneinrichtung. Das Fühlergehäuse 1 weist zwei Elektroden 3 und k auf, die als Elektrode 3 bzw. als Bezugselektrode H fungieren. Die Elektroden 3 und 4 führen in das Fühlergehäuse 1, wobei die Einführung höchst abdichtend geschaffen ist und im Inneren des Gehäuses mit einem hier nicht näher beschriebenen Meftuandler verbunden sind.Figure 1 shows the entirety of the leak warning device according to the invention. The sensor housing 1 has two electrodes 3 and k , which function as electrode 3 and reference electrode H, respectively. The electrodes 3 and 4 lead into the sensor housing 1, whereby the introduction is made to be highly sealing and are connected inside the housing to a membrane converter, not described in detail here.
über die Kabelkanäle 7 und 8, die beide in die Stellverschraubung 2 führen,sind der auf dem Anschlagwinkel 5 angeordnetene Anschlußkopf 11 und das Fühlergehäusel ver bun den. Die Überwurfmutter 9 dient zur Abdichtung des Kabelkanals gegenüber dem Anschlußkopf. Mittels den im Anschlagwinkel 5 vorgesehenen Bohrung 6 wird die komplette Leckwarneinrichtung an die Behälterwand verschraubt oder in ähnlicher Weise befestigt. Mit der StellverschraubungThe connection head 11 arranged on the stop bracket 5 and the sensor housing 1 are connected via the cable ducts 7 and 8, both of which lead into the adjusting screw connection 2. The union nut 9 serves to seal the cable duct from the connection head. The complete leak warning device is screwed to the container wall or secured in a similar way using the hole 6 provided in the stop bracket 5.
2 wird die gewünschte Tiefenlage des Meßfühlers in den Behälter eingestellt«und arretiert.2 The desired depth of the sensor is set in the container and locked.
Figur 2 zeigt eine Ansicht des Anschlagwinkels 5 aus der in Figur 1 angedeuteten Richtung A. In dieser Ansicht wird eine Kabelklemmvorrichtung am Anschlußkopf 11 sichtbar,an die ein Kabel angeschlossen wird, das ein durch den Meßwandler verarbeitetes Signal an eine Warneinrichtung, z. B. eine rote Lampe oder Sirene weitergibt. Hierbei ist ein Meßverstärker zwischengeschaltet.Figure 2 shows a view of the stop angle 5 from the direction A indicated in Figure 1. In this view, a cable clamping device on the connection head 11 is visible, to which a cable is connected that transmits a signal processed by the measuring transducer to a warning device, e.g. a red lamp or siren. A measuring amplifier is connected in between.
Während der ständig durchgeführten Messung liegt die Elektrode 4 auf Masse. Mit der Elektrode 3 wird eine zwischen Elektrode 3 und 4 bestehende Kapazität erfaßt. Diese Kapazität ändert sich, in dem Moment, in dem eine Flüssigkeit zwischen den beiden ElektrodenDuring the continuous measurement, electrode 4 is connected to ground. Electrode 3 is used to measure a capacitance between electrodes 3 and 4. This capacitance changes the moment a liquid is placed between the two electrodes.
3 und 1I aufsteigt.3 and 1 I rises.
Die erfindungsgemäße Auslegung dieser Leckwarneinrichtung ermöglicht die Bereitstellung eines Frühwarnsystems, das also schon nach Austreten geringster Mengen von Flüssigkeiten ein Warnsignal abgibt.The inventive design of this leak warning device enables the provision of an early warning system that emits a warning signal even after the smallest quantities of liquids have leaked out.
