Description

Grubenlampe mit Schlagwetteranzeigevorrichtung, bei der von der Flamme der Grubenlampe ein Schmelzkontakt nur beim Auftreten von Grubengasen geschmolzen wird, der ein Auslöschen der Grubenlampenflamme veranlaßt. Die Erfindung betrifft eine Grubenlampe mit Schlagwetteranzeigevorrichtung, bei der von der Flamme der Grubenlampe ein Schmelzkontakt nur beim Auftreten von Grubengasen geschmolzen wird, der ein Auslöschen der Grubenlarnpenflamme veranlaßt. Das charakteristische Merkmal der Erfindung besteht nun darin, daß drei Kontakte mit verschieden hohem Schmelzpunkt im Bereich der Flamme liegen, von denen jeder bei seinem Schmelzen eine gemeinsame elektromagnetische Auslöschvorrichtung der Flamme und eine Klingel zum Ansprechen bringt, um ein sicheres Ansprechen der Schlagwetteranzeigevorrichtung zu bewirken und um feststellen zu können, welche Wärmegrade durch die Grubengase veranlaßt worden sind, so daß der Prozentgehalt in der Luft bestimmt werden kann.Mining lamp with firedamp indicator, by the flame the miner's lamp melted a melting contact only when mine gases occurred which causes the mine lamp flame to go out. The invention relates to a miner's lamp with a firedamp indicator, in which the flame of the Mine lamp a melting contact is only melted when mine gases occur, which causes the pit lamp's flame to be extinguished. The characteristic feature the invention now consists in the fact that three contacts with different high melting points lie in the area of the flame, each of which has a common when it melts electromagnetic flame extinguishing device and a bell brings to respond to a reliable response of the firedamp display device to effect and to be able to determine which degrees of heat through the mine gases have been caused so that the percentage in the air can be determined.

Die Zeichnung stellt eine Grubenlampe i dar, durch die Grubenwetter, die sich in Bergwerken bilden, laut gemeldet werden, gleichzeitig wird hierbei auch die Flamme der Grubenlampe ausgelöscht, bevor sich die Wetter entzünden.The drawing shows a miner's lamp i, through the miner's weather, that form in mines, are reported loudly, at the same time this is also extinguished the flame of the miner's lamp before the weather ignites.

Die Konstruktion dieser Grubenlampe ist folgende: Oberhalb des Grubenlanipenkorbes 20 sind drei Schmelzkontakte 1, 2, 3 angebracht, die bei d.0°, 6o°, 8o° flüssig werden, so daß dann elektrische Kontakte in Berührung kommen und eine Klingel 5 in Verbindung mit einer elektrischen Batterie 6 in Betrieb kommt. Gleichzeitig wird auch die Lampe ausgelöscht durch Umschlagen einer Klappe 7 auf die Flamme 8 vermittels eines Magneten 9 in der Lampe, der auch mit in den elektrischen Stromkreis eingeschlossen ist. Diese Klappe 7 hat ein Gegengewicht i o, welches die Klappe wieder von der gelöschten Flamme hochzieht, wenn man den elektrischen Stromkreis unterbricht. Der niedrigste Schmelzkontakt i von -to' ist aus einer Emulsion tierischer und pflanzlicher Fette, Metallspäne, Schrot und einem Metallstab t i in der Mitte hergestellt. Dieser Schmelzkontakt i ruht in einer unten offenen Kontaktpfanne. Bei -Io°. Wärme fließt die Emulsion. und mit ihr fällt auch der Metallstab i i und die 'Metallspäne in eine geschlossene Pfanne des zweiten Kontaktes und bringt dann beide elektrische Kontakte in metallische Berührung, wodurch der elektrische Stromkreis geschIcssen wird. Der zweite Schmelzkontakt 2 besteht aus einem bei 6o° schmelzenden Metallring 12, der isoliert zwischen einer Kontaktfeder 13 und der anderen Kontaktunterlage 14 liegt. Schmilzt der Kontaktring 12, dann drückt der Federkontakt 13 auf den Kontakt 14, schließt den elektrischen Stromkreis, wodurch ebenfalls die Klingel 5 und die Flaininenlöschklappe 7 in Betrieb gesetzt werden. Diese beiden vorbeschriebenen elektrischen Kontakte lassen sich sehr leicht und ohne Lötung erneuern.The construction of this miner's lamp is as follows: Above the miner's lane basket 20 three melting contacts 1, 2, 3 are attached, the liquid at d.0 °, 6o °, 8o ° so that electrical contacts come into contact and a bell 5 in connection with an electric battery 6 comes into operation. At the same time will also extinguished the lamp by folding a flap 7 on the flame 8 by means of a magnet 9 in the lamp, which is also included in the electrical circuit is. This flap 7 has a counterweight i o, which the flap again from the extinguished flame when the electrical circuit is interrupted. Of the lowest melting contact i of -to 'is made of an emulsion of animal and vegetable Fats, metal shavings, shot and a metal rod t i made in the middle. This Melt contact i rests in a contact pan that is open at the bottom. At -Io °. Heat flows the emulsion. and with it the metal rod i i and the 'metal shavings fall in a closed pan of the second contact and then brings both electrical Contacts in metallic contact, thereby closing the electrical circuit will. The second melting contact 2 consists of a metal ring melting at 60 ° 12, which isolates between a contact spring 13 and the other contact pad 14 lies. When the contact ring 12 melts, the spring contact 13 presses on the contact 14, closes the electrical circuit, which also causes the bell 5 and the Flaininen extinguishing flap 7 can be put into operation. These two previously described electrical contacts can be renewed very easily and without soldering.

Der dritte Schmelzkontakt 3 besteht aus der Feder i-, die mit dein äußeren Ende auf einem unteren Kontakt 15 mit Leichtlot von 8o° an festgelötet ist. Schmilzt diese Lötung, so springt die Feder i-. nach oben gegen einen Kontakt 16, und der elektrische Stromkreis ist ebenfalls geschlossen. Drei verschiedene hohe Schmelzkontakte sind zum unbedingt sicheren Funktionieren der Grubenlampe angebracht und auch, um feststellen zu können, welch hohe Wärmegrade durch die Grubengase eingetreten sind, so daß dann der Prozentgehalt in der Luft geschätzt werden kann. Die Schmelzkontakte, angebracht in feuergefährlichen Räumen, verbunden mit elektrischer Fernleitung und Scheller, können auch als Feuermelder ausgeführt werden. Bei normaler Höhe und Wärmeentwicklung der Flamme in der Grubenlampe schmelzen die Kontakte nicht, sondern nur wenn Wettergase die Flamme vergrößern und die Wärmegrade der Schmelzkontakte übersteigt. Dieses geschieht schon, bevor die Flamme aus dem Grubenlampenkorb ragt, wodurch ein Zünden der Wettergase durch die Flamme vermieden wird. Alle funktionierenden Teile dieser Grubenlampe werden unter dichten Verschluß gelegt, damit keine Gaszündung durch das Funktionieren der Lampe verursacht werden kann. Die Schmelzkontakte können für jede über 4.o° liegende Grade hergestellt werden.The third fusible contact 3 consists of the spring i-, which is connected to your outer end is soldered to a lower contact 15 with light solder from 8o °. If this soldering melts, the spring jumps i-. up against a contact 16, and the electrical circuit is also closed. Three different highs Melt contacts are attached to ensure that the miner's lamp functions reliably and also to be able to determine the high degrees of heat caused by the mine gases so that the percentage in the air can then be estimated. The melting contacts, installed in flammable areas, connected to electrical transmission lines and Scheller can also be used as fire alarms. At normal altitude and heat development the flame in the miner's lamp does not melt the contacts, but only if there are weather gases enlarge the flame and exceed the heat levels of the melting contacts. This happens before the flame protrudes from the pit lamp basket, causing ignition of the weather gases is avoided by the flame. All working parts of this Mining lamps are placed under a tight seal to prevent gas ignition the functioning of the lamp can be caused. The fusible contacts can be used for every degree above 4.o ° can be produced.
