Description
Füllungsstandanzeiger nach Patent 463114 mit Fernmeldung durch eine Selenzelle Beim Füllungsstandanzeiger für Kohlenbunker u. dgl. nach -dem Hauptpatent sind die Glühlampen in einer im Innern des Bunkers befestigten und mit Schaulöchern versehenen Röhre angeordnet. Im 'Bunkermantel sind weitere Schaulöcher vorgesehen, so daß durch beide Schaulöcher die Lichtstrahlen der Glühlampe nur dann fallen, wenn der Kohlenstaub im: Bunker bis unter die beiden jeweiligen Schaulöcher gesunken ist. Außerhalb des Bunkers sind an einer geschützten Stelle Selenzellen angeordnet, die in der üblichen Weise auf Signalstromkreis einwirken, um den Füllungsstand des Bunkers aus der Ferne beobachten zu können.Level indicator according to patent 463114 with remote reporting by a Selenium cell For the level indicator for coal bunkers and the like according to the main patent the light bulbs are fixed inside the bunker and have peepholes provided tube arranged. Further peepholes are provided in the bunker jacket, so that the light rays of the incandescent lamp only fall through both peepholes when the coal dust in the: bunker has sunk below the two respective peepholes is. Outside the bunker, selenium cells are arranged in a protected place, which act on the signal circuit in the usual way to check the level of the Watching bunkers from a distance.
Die Anordnung nach dem Hauptpatent soll gemäß der Erfindung dadurch verbessert werden, daß die Selenzellen zum Zwecke des Schutzes gegen Ermüdungserscheinungen durch, hochziehbare Schutzplatten abgedeckt werden. Zweckmäßig ist die Bewegung der Schutzplatten elektrisch gesteuert.The arrangement according to the main patent is intended according to the invention be improved that the selenium cells for the purpose of protection against symptoms of fatigue be covered by pull-up protective panels. The movement is useful the protective plates are electrically controlled.
Die Abdeckung lichtelektrischer Zellen isi an sich nicht neu. Bei Einbruch.- und Feuermeldeanlagen muß man die Zellen z. B. dann abdecken, wenn man ein Ansprechen durch das Tageslicht vermeiden will. Auch ist vorgeschlagen worden, das Licht auf die Selenzellen nicht dauernd, sondern intermittierend mit Hilfe einer rotierenden Wand auffallen zu lassen. Bei dieser Anordnung handelt es sich aber nicht, wie bei der Erfindung, darum, die. Selenzellen während der Dauer des Nichtgebrauchens gegen Ermüdungserscheinungen zu schützen; denn bei den Füllungsstandanzeigern kommt eine dauernde Einwirkung auf die Selenzellen nicht in Frage, sondern es genügt, wenn von Zeit zu Zeit Kontrollhelichtungen vorgenommen werden, um den Füllungsstand des Bunkers zu ermitteln. Während der übrigen Zeit haben die Zellen keine Aufgabe zu erfüllen. Um sie während dieser Perioden nicht unnötig zu beanspruchen, sind gemäß der Erfindung die hochziehbaren Schutzplatten vorgesehen.The coverage of photoelectric cells is not in itself new. at Einbruch.- and fire alarm systems you have to open the cells z. B. then cover when you wants to avoid being addressed by daylight. It has also been suggested the light on the selenium cells is not permanent, but intermittent with the help of a rotating wall to attract attention. However, this is the case not, as with the invention, about the. Selenium cells during the period of non-use to protect against signs of fatigue; because comes with the level indicators permanent action on the selenium cells is not in question, it is sufficient if from time to time control exposures are made to the fill level of the bunker. During the rest of the time, the cells have no function to meet. In order not to stress them unnecessarily during these periods according to the invention, the pull-up protective panels are provided.
Die Erfindung ist in der Abb. r in der Vorderansicht, in der Abb. 2 im: Schnitt dargestellt. Die Selenzelle a ist in einem Kasten b untergebracht. Die Lichtstrahlen kommen von der .Seite c in Richtung des Pfeiles. Die Schutzplatte ist mit d bezeichnet und. befindet sich, in der - Bewegungsrichtung des Lichtstrahles gesehen, vor der Selenzelle. Sie trägt eine kolbenartige Verlängerung e, die in die Spule/ hineinragt. Wird die Spule erregt, so wird der Anker e und damit die Schutzplatte hochgezogen, so daß der Lichtstrahl auf die Selenzelle auffallen kann: Zur Steuerung der Spule f kann z. B. ein Druckknopf auf der Schaltbrücke vorgesehen sein, der von dem überwachungspersonal niedergedrückt wird, wenn der Stand der Bunkerfüllung festgestellt werden soll.The invention is shown in Fig. R in the front view, in Fig. 2 in: section. The selenium cell a is housed in a box b. The light rays come from .Seite c in the direction of the arrow. The protective plate is denoted by d and. is located in front of the selenium cell, seen in the direction of movement of the light beam. It carries a piston-like extension e that protrudes into the coil /. If the coil is excited, the armature e and thus the protective plate is pulled up so that the light beam can strike the selenium cell. B. a push button on the switching bridge can be provided, which is depressed by the surveillance staff when the status of the bunker filling is to be determined.
Ein Fernmelder ist in der Abb.3 darge# stellt, und zwar mit nur einer Lichtöffnung. Der Fernmelder ist in der oberen Hälfte der Lichtöffnung angebracht, so daß die untere Hälfte das Licht der im Innern des Bunkers angebrachten Glühlampe durchläßt. Man kann hierdurch den Füllungszustand im Bunker auch mit bloßem Auge beobachten, während der Fernmelder den Füllungsstand an der Schaltbrücke anzeigt.A telecommunication device is shown in Fig. 3, with only one Light opening. The remote indicator is placed in the upper half of the light opening, so that the lower half receives the light from the incandescent lamp inside the bunker lets through. You can see the filling level in the bunker with the naked eye while the remote indicator shows the fill level on the switching bridge.
