Description
Schlagwetter-Meldegerät Es sind Schlagwetter-Veldegcräte für Gruben bekannt, die nicht handlich genug sind, um von einer größeren Anzahl von Bergleuten ständig benutzt werden zu können.Firedamp signaling device They are firedamp devices for pits known that are not handy enough to be used by a large number of miners to be able to be used all the time.
Die Erfindung hat ein Schlagwetter-Meldegerät zum Gegenstand und besteht darin, daß es als Armbanduhr mit Ableseskala ausgebildet ist, so daß eine größere Zahl von Bergleuten stets das Schlagwetter-Meldegerät ohne Behinderung mit sich führen können. Der Schlagwetteranzeiger in dem Gerät kann aus einem methanempfindlichen Katalysator, beispielsweise in Form einer Platte aus einer Platinverbindung, oder auch aus feuchten, chemischen, mit Methan reagierenden Stoffen bestehen, wobei die Meßergebnisse von dem Gerät auf einer Skala nach Art eines Zifferblatts ablesbar sind. Das Gerät kann jeden Grad der Methanbeimischung in Grubenwettern oder auch nur den gefährlichen Grad innerhalb einer Gefahrenzone angeben und so den Bergmann warnen. Für die Ausbildung des Geräts als Armgerät nach Art einer Armbanduhr spricht die Möglichkeit, schnell und ohne Zeitverlust auch Ecken unter dem Hangenden und Bohrungen auf Schlagwetteranreicherung, beispielsweise vor dem Schießen, untersuchen zu können. The subject of the invention is a firedamp signaling device and is that it is designed as a wristwatch with a reading scale, so that a Larger number of miners always use the firedamp detection device without hindrance can lead. The firedamp indicator in the device can consist of a methane-sensitive Catalyst, for example in the form of a plate made of a platinum compound, or also consist of moist, chemical substances that react with methane, whereby the Measurement results from the device can be read off on a dial-type scale are. The device can handle any degree of methane admixture in mine weather or also only indicate the dangerous degree within a danger zone and so indicate the miner to warn. For the training of the device as an arm device in the manner of a wristwatch speaks the possibility of quickly and without wasting time also corners under the hanging wall and Examine boreholes for firedamp accumulation, for example before shooting to be able to.
