Description
Stationäre Gaswarn- und Meldegeräte, bei denen die Kontaktgeber (Katalytenkörbe auf Schaltthermometern, z. B. U-förmigen Differential-Ausgleich-Schaltröhren) fest auf dem Boden des Gerätegehäuses aufgebaut werden, sind bekannt. Stationary gas warning and signaling devices in which the contactors (catalyst baskets on switch thermometers, e.g. B. U-shaped differential equalization interrupters) firmly be built on the bottom of the device housing are known.
Der Abstand zwischen der Quecksilbersäule und den elektrischen Kontakten in der Schaltröhre richtet eich nach den anzuzeigenden Gasen bzw. Gas-Luft-Gemischen und kann nur durch Einschütteln hergestellt werden. Solche Einstellungen und Nachjustagen ssind auch nach Fertigstellung der Anlagen in fast allen Fällen erforderlich. Zu diesem Zweck mußten dann die Geräte abgeschraubt und oft zusätzllich auch die elektrischen Anschlüsse gelöst werden. Alle diese Manipulationen sind verhältnismäßig schwierig, wenn man bedenkt, daß derartige Anlagen in den meisten Fällen unter der Decke der zu überwachenden Räume installiert werden müssen. The distance between the column of mercury and the electrical contacts in the interrupter is based on the gases or gas-air mixtures to be displayed and can only be made by shaking it in. Such settings and readjustments s are required in almost all cases even after the systems have been completed. to For this purpose the devices had to be unscrewed and often also the electrical ones Connections are loosened. All of these manipulations are relatively difficult, if you consider that such systems are in most cases under the roof of the rooms to be monitored must be installed.
Weiterhin wurde bisher der Katalysatorenkorb auf dem Reaktionsschenkel des Schaltthermometers durch starre, auf dem Gebäuseboden befestigte Halter in Stellung gehalten, so daß Stöße und temperaturbedingte M ateri alverspannungen zu Beschädigungen führen und damit eine Explosiionsgefahr heraufbeschwören können. Furthermore, the catalyst basket was previously on the reaction leg of the switching thermometer in position by means of rigid brackets attached to the base of the housing held, so that shocks and temperature-related M ateri alverspannungen cause damage lead and thus can conjure up a risk of explosion.
Diesen Übelständen abzuhelfen, ist Zweck vorliegender Erfindung, deren Wesen darin besteht, daß einmal der Kontaktgeber auf einer besonderen Montageplatte od. dlgl. angeordnet ist, welche vermittels federnden Handhebels bequem in vorgesehene Führungen des Gehäusebodens einsetzbar und herausnehmbar angeordnet ist, wodurch die Justage bzw. Nachjustage mühelos durchgeführt werden kann, ohne das Gerät abschrauben oder elektrische Anschlüsse lösen zu müssen, und daß zum andern Katalysatorenkorb und Reaktionsschenkel des Schaltrohres vermittels einer geeigneten Feder relativ beweglich zueinander gehalten sind. To remedy these evils is the purpose of the present invention, the essence of which is that once the contactor is on a special mounting plate or the like. is arranged, which by means of resilient hand lever conveniently in provided Guides of the housing base can be inserted and removed, whereby the adjustment or readjustment can be carried out effortlessly without unscrewing the device or to loosen electrical connections, and that to the other catalyst basket and reaction leg of the switching tube by means of a suitable spring relative are kept movable to each other.
In der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform schematisch dargestellt. Es zeigt Abb. I eine Vorderansicht und Abb. 2 eine Seitenansicht. In the drawing the invention is in an exemplary embodiment shown schematically. It shows Fig. I a front view and Fig. 2 a side view.
Ein Schutzdeckel über dem Kontaktgeber ist nicht besonders gezeigt. Derselbe hat den Vorschriften für den Bau von schlagwetter- und explosionssicheren Geräten zu entsprechen. A protective cover over the contactor is not specifically shown. The same has the regulations for the construction of firedamp and explosion-proof Devices to match.
Auf dem unteren Teil des Gehäusebodens I ist der vorschriftsmäßige Anschlußkasten 2 für die elektris oben Leitungen vorgesehen. Auf dem oberen Teil des Gehäusebodens ist der Kontaktgeber, bestehend aus dem Schaltrohr 3 und dem Katalysatorenkorb 4 indirekt angeordnet, indem er auf einer besonderen Montageplatte 5 od. dgl. befestigt ist, die in Schlitze 6 und 6a des Gehäusebodens einführbar und vermittels eines unter Einwirkung einer Feder 7 stehenden Bolzens 8 mit Handhebel 9 in einem Haltering 10 des Gehäusebodens in Stellung bringbar oder aus derselben lösbar ist. On the lower part of the case back I is the correct one Terminal box 2 provided for the electrical cables above. On the upper part the bottom of the housing is the contactor, consisting of the switching tube 3 and the catalytic converter basket 4 arranged indirectly by being attached to a special mounting plate 5 or the like is, which can be inserted into slots 6 and 6a of the housing bottom and by means of a under the action of a spring 7 standing bolt 8 with hand lever 9 in a retaining ring 10 of the housing bottom can be brought into position or released from the same.
Der Katalysatorenkorb 4, welcher auf einem Anschlag I I des Realtionsschenkeis I2 der Schaltröhre ruht, wird durch eine geeignete Feder 13, welche gegen einen Anschlag 14 des Raktionsschenkelendes wirkt, in Stellung gehalten, so daß Katalysatorenkorb und Reaktionsschenkel sich relativ beweglich zueinander befinden. Hierdurch werden Stöße und temperaturbedingte Materialverspannungen auf gefangen. The catalyst basket 4, which on a stop I I of the Realtionsschenkeis I2 of the interrupter rests, is by a suitable spring 13, which against a Stop 14 of the Raktionsschenkelendes acts, held in position, so that catalyst basket and reaction legs are relatively moveable to one another. This will be Shocks and temperature-related material tension are absorbed.
