Description
Probenahmegerät für Gas Für die Probenahme zur Gasprüfung mit gebräuchlichen Gasprüfgeräten (z. B. mit Methanprüfern oder Explosimetern) werden an schwer zugänglichen und gefährlichen Stellen sowie bei dei Feststellung von Gasschichtungen Schläuche, die an Stangen befestigt werden, und Rohre verwendet.Sampling device for gas For sampling for gas testing with common Gas testing devices (e.g. with methane detectors or explosimeters) are installed on those that are difficult to access and dangerous places as well as hoses when gas layers are detected, which are attached to poles and pipes are used.
Die Handhabung dieser Hilfsgeräte ist umständlich und zeitraubend. Ein weiterer Mangel besteht darin, daß die gesamte im Schlauch oder Rohr vc dem Ansaugen der Probe befindliche Luft zunächst durch die Meßkammer und vorgelagerten Filter gepumpt werden muß, ein Umstand, der für die Meßkammer und Filter von Nachteil ist. Ferner wird -falls nicht eine Hilfsperson mitwirkt - der Prüfen für die Probenahme beide Hände benötigen, nämlich die eine Hand zum Betätigen der am Gerät befindlichen Pumpe, die andere Hand zum Halten des Ansaugrohres oder -schlauches. Eine solche Handhabung ist vielfach, z. B. im Bergbau, sehr nachteilig. The handling of these auxiliary devices is cumbersome and time consuming. Another shortcoming is that the entire in the hose or tube vc dem The air present in the sample is first sucked in through the measuring chamber and upstream Filter must be pumped, a fact that is disadvantageous for the measuring chamber and filter is. Furthermore - if an assistant is not involved - the testing for the sampling need both hands, namely one hand to operate the one on the device Pump, the other hand to hold the suction tube or hose. Such Handling is multiple, e.g. B. in mining, very disadvantageous.
Schließlich muß bei Wiederholungsmessungen dei Probenahmevorgang jeweils wiederholt werden, wei] die Schläuche und Rohre keine zuverlässige Speicherung von Probegas gestatten.Finally, in the case of repeated measurements, the sampling process must be carried out in each case be repeated because the hoses and pipes do not provide reliable storage Allow sample gas.
Der Erfindung lag die Aufgabe zugrunde, ein Probenahmegerät zu entwickeln, das kleine Abmessungen hat, nur Probegas an die Meßkammern und Filter abgibt, das es ermöglicht, den gesamten Vorgang der Probenahme mit einer Hand auszuführen und Wiederholungsmessungen ohne erneute Probenahme gestattet. The invention was based on the object of developing a sampling device which has small dimensions, only releases sample gas to the measuring chambers and filters, it enables the entire sampling process to be carried out with one hand and Repeat measurements permitted without renewed sampling.
Erfindungsgemäß geschieht das durch folgenden Aufbau: Das Ansaugrohr ist als teleskopartig ausziehbares Rohr gestaltet, an dem sich ein armlangel Schlauch befindet, der in einer Aufsteckmuffe endet (Abb. 1). According to the invention, this is done by the following structure: The intake pipe is designed as a telescopic tube with an arm-length hose attached to it which ends in a socket (Fig. 1).
Über dem untersten Rohrstück, das mit einer Bohrung versehen ist, ist zweckmäßig ein Pumpballon geschoben. Er gestattet gleichzeitiges Pumpen und Halten des ausgezogenen Ansaugrohres mit einer Hand (Abb. 2). Above the lowest pipe section, which is provided with a hole, a pump balloon is expediently pushed. It allows simultaneous pumping and Hold the extended suction tube with one hand (Fig. 2).
Zwischen dem Ansaugrohr und dem Anschlußschlauch ist zweckmäßig ein Behälter, z. B. eine Gummiblase als Speicherbehälter eingefügt (Abb. 3). Between the suction pipe and the connection hose there is a practical one Container, e.g. B. inserted a rubber bladder as a storage container (Fig. 3).
