Die Zusatzpatentanmeldung P 17 92 972.5-12 zum Patent 1150 24S betrifft eine Einrichtung zur Anzeine von Undichtheiten an doppelwandigen Laaerbehältern für Flüssigkeiten oder Gase. an deren Wandzwischenraum eine Vakuumpumpe mit druckabhängiger Einsatzregelung angeschlossen ist, welche den Druck im Wandzwischenraum selbsttätig innerhalb eines bestimmten Unterdruckbereiches (Drucksollxvert) hält. Dabei sind blittel vorgesehen. die eine Verzögerung oder ein Ausbleiben der Herbeiführung des Drucksollwertes in dem Wandzwischenraum als Kriterium einer Leckage anzeigen. I : m im Fall der Beschädigung der inneren oder äußeren Wandschale des doppelwandigen Lagerbehälters zu vermeiden, daß flüssiges Lagergut oder Grundwasser aus dem Wandzvischenraum von der Pumpe angesaugt wird. ist in der Saugleitung oder in einer an die Vakuumpumpe anschließenden Leitung eine auf etwaiges Leckmedium oder dessen Dämpfe ansprechende Flüssigkeitsspürsonde derart angeordnet. daß beim Ansaugen von Leckflüssigkeit durch die Vakuumpumpe ein Alarm- und/oder ein Steuersignal ausgelöst wird. Eine bevorzugte Ausführungsform gemäß Anspruch 2 des genannten Zusatzpatentes besteht darin. daß die Spürsonde ein Auffanggefäß für Leckflüssigkeit aufweist. The additional patent application P 17 92 972.5-12 to patent 1150 24S concerns a device for indicating leaks on double-walled Laaerbehältern for liquids or gases. a vacuum pump with pressure-dependent Insertion control is connected, which automatically increases the pressure in the space between the walls holds within a certain negative pressure range (pressure setpoint xvert). Are there planned. the delay or failure to bring about the Show pressure setpoint in the wall gap as a criterion of a leak. I. : m in case of damage to the inner or outer wall shell of the double-walled Storage container to avoid that liquid stored goods or groundwater from the wall space is sucked in by the pump. is in the suction line or in one of the vacuum pumps subsequent line a responsive to any leak medium or its vapors Liquid detection probe arranged in this way. that when sucking in leakage fluid through the vacuum pump triggers an alarm and / or a control signal. A preferred one Embodiment according to claim 2 of said additional patent consists in this. that the probe has a receptacle for leakage fluid. Eine solche Leckanzeigeeinrichtung mit Auffanggefäß wird erfindungsgemäß dadurch weiter ausgestaltet. daß in dem Auffanggefäß in an sich bekannter Weise ein Schwimmer angeordnet ist. der zur Steuerung eines elektrischen Schalters und'oder zur mechanischen Steuerung eines in der Leitung angeordneten Absperrventils dient. Such a leak indicator device with a collecting vessel is according to the invention thereby further developed. that in the collecting vessel in a known manner a float is arranged. to control an electrical switch and'or serves to mechanically control a shut-off valve arranged in the line. Der Schwimmer in dem Auffanggefäß stellt nicht nur eine besonders einfache, sondern auch eine besonders betriebssichere Steuervorrichtung dar. Der Schwimmer kann z. B. in an sich bekannter Weise durch ein Seil mit Gegenaewicht und Rolle oder durch eine Schaltbebelübertragung den elektrischen Schalter steuern. Durch ein von dem Schwimmer gesteuertes Absperrventil in der Saug- oder Druckleitung der Vakuumpumpe kann bei einer bestimmten Steighöhe ein Verschluß der Saug- oder Druckleitung auf mechanischem Weg herbeigeführt werden, so daß ein Austritt von Leckageflüssigkeit oder Grundwasser in den Aufstellungsraum der tXberwachungsaeräte. z. B. den Keller eines mit Ölheizung ausgestatteten Wohnhauses, verhindert wird. The float in the collecting vessel is not just one special simple, but also a particularly reliable control device. The Swimmers can e.g. B. in a known manner by a rope with counter weight and roll or control the electrical switch by a switch toggle transmission. By a shut-off valve in the suction or pressure line controlled by the float the vacuum pump can be a closure of the suction or Pressure line to be brought about mechanically, so that an escape of Leakage liquid or groundwater in the room where the monitoring devices are installed. z. B. the basement of a house equipped with oil heating is prevented. Der von dem Schwimmer gesteuerte Schalter kann in weiterer Ausbildung der Erfindung so angeordnet sein, daß er bei einer vorbestimmten Steighöhe der Leckflüssigkeit den Antriebsstromkreis der Vakuumpumpe unterbricht und/oder das Steuer- oder Alarmsignal auslöst.The switch controlled by the float can be used in further training the invention be arranged so that it is at a predetermined height of the leakage interrupts the drive circuit of the vacuum pump and / or the control or alarm signal triggers. Der Schaltvorgang kann je nach Bedarf so erfolgen, daß die Pumpe durch den Schwimmerschalter ausgeschaltet werden kann, so daß das Wiedereinschalten durch eine andersartige Betätigung des Schalters beispielsweise von Hand. erfolgen muß. Die Pumpe kann aber erforderlichenfalls auch je nach Steighöhe der Leckageflüssigkeit durch den Schwimmerschalter eine und ausgeschaltet verden. so daß der Pegel der Leckageflüssigkeit im Rohrleitungssystem zwischen bestimmten Steighöhen hin und her pendelt. The switching process can be carried out as required so that the pump can be switched off by the float switch, so that it can be switched on again by actuating the switch in a different manner, for example by hand. take place got to. The pump can, however, if necessary, also depending on the height of the leakage liquid on and off with the float switch. so that the level of the Leakage fluid in the pipeline system between certain heights commutes here.
