Description
Vorrichtung zur Bekämpfung von Grubenexplosionen, bei der eine Klappe einen Stromkreis schließt Es ist bereits bekannt, beim Auftreten von Explosionen vermittels eines elektrischen Stromkreises Gesteinsstaubbehälter zu öffnen, in welche die Preßluftleitung hineingeführt ist, so daß der Staub durch die Preßluft aus der Leitung-ausgeblasen wird. Ebenso ist es bereits bekannt, durch Explosionsklappen einen: Stromkreis zu schließen, der eine Sprengpatrone zur Explosion bringt, so daß Gesteinsstaubbehälter bzw. Wasserbehälter ihren Inhalt entleeren. Nicht mehr neu ist es auch, daß der Stromkreis das Ventil einer Wasserleitung öffnet, so daß ein den ganzen Streckenquerschnitt einnehmender -Wasserschleier gebildet wird: Die technischen Vorzüge des Gegenstandes der Erfindung beruhen auf der Anwendung des zu sprengenden Blindflanschenverschlusses, welcher einen guten Abschluß der Preßluftleitung herstellt und im Falle einer Explosion betriebssicher arbeitet.Device for fighting mine explosions with a flap It is already known when an explosion occurs by means of an electrical circuit to open rock dust containers into which the compressed air line is inserted so that the dust through the compressed air from the Line-blown. Likewise, it is already known through explosion flaps one: to close a circuit that causes an explosive cartridge to explode, so that rock dust containers or water containers empty their contents. No longer It is also new that the circuit opens the valve of a water pipe so that a water veil covering the entire cross-section of the route is formed: The technical advantages of the subject matter of the invention are based on the application of the to be blown blind flange closure, which a good closure of the compressed air line and works reliably in the event of an explosion.
Die Vorrichtung dient zum Niederschlagen einer entstandenen Grubenexplosion durch Ausblasen von Gesteinsstaub in die angrenzenden Strecken.The device serves to knock down a mine explosion that has occurred by blowing rock dust into the adjacent stretches.
Sie besteht aus einem in die Preßluftleitung a eingebauten Blindflanschengeh,äuse b, in dem zwei abgedichtete Glasscheiben c angeordnet sind (Fig.2). Zwischen diesen befindet sich eine Sprengkapsel d, die durch eine Schaltvorrichtung e und eine elektrische Batterie j zur Entzündung gebracht wird. Hierbei werden die beiden Blindflanschenglasscheiben c gesprengt, so daß die Preßluft in die Gesteinsstaubbehälter g durch die Blasrohre lt entweichen kann. Durch die ausströmende Preßluft wird der Gesteinsstaub aus dem Behälter g in die Strecken ausgeblasen. Ein im Auslauf des Behälters g angeordneter Ventilatorflügel j sorgt für ein gutes Auswirbeln des Gesteinsstaubes.It consists of a blind flange housing built into the compressed air line a , housing b, in which two sealed glass panes c are arranged (FIG. 2). Between these there is a detonator d which is ignited by a switching device e and an electric battery j. Here, the two blind flange glass panes c are blown so that the compressed air can escape into the rock dust container g through the blowpipes lt. The rock dust is blown out of the container g into the routes by the compressed air flowing out. A fan blade j arranged in the outlet of the container g ensures that the rock dust is swirled out well.
Als Schaltorgan dient eine mit Kontakten k versehene, frei in einem Kasten aufgehängte Schaltklappe 1, die durch den Explosionsdruck betätigt wird. Die Betätigung kann von beiden Seiten erfolgen. Durch geeignete Schaltung der elektrischen Kabel können von der Schaltklappel mehrere Gesteinsstaubbehälter in Tätigkeit gesetzt werden. Zur Vermeidung einer unbefugten Betätigung der Schaltklappe l ist die Schaltvorrichtung mit einem beiderseits angeordneten Sieb s versehen.As a switching element is provided with contacts k, free in one Box suspended switching flap 1, which is actuated by the explosion pressure. It can be operated from both sides. By suitable switching of the electrical Cables can activate several rock dust containers from the switching flap will. To avoid unauthorized actuation of the switching flap l, the switching device provided with a sieve s arranged on both sides.
Die Anordnung der Apparate in der Strecke geht aus Fig. i hervor.The arrangement of the apparatus in the line is shown in FIG.
