Description

Die Erfindung bezieht sich auf eine Vorrichtung für Übungsminen zur Freigabe von Lichtbojen über eine Verzögerungseinrichtung, wobei in der Ruhestellung die Lichtboje in einem Minengefäß über lösbare Halteelemente in einer durchgehenden Aufnahmeöffnung angeordnet ist und in der Arbeitsstellung aufschwimmt sowie über eine Lichtleine mit dem Minengefäß verbunden bleibt.The invention relates to a device for training mines for releasing light buoys via a delay device, wherein in the rest position the light buoy is arranged in a mine vessel via releasable holding elements in a continuous receiving opening and floats in the working position and remains connected to the mine vessel via a light line.

Bei Minen dieser Art ist es erforderlich, nach einer Übung das Auffinden der Minen und somit das Bergen zu gewährleisten. Hierbei besteht das Problem darin, für die Trennvorrichtung der Lichtboje einfache Steigzeitverzögerungseinrichtungen zu verwenden, die eine gute Voreinstellung ermöglichen und ohne großen Aufwand eine Bereitstellung mit dieser Voreinstellung gewährleisten.With mines of this type, it is necessary to ensure that the mines are found and thus recovered after an exercise. The problem here is to use simple rise time delay devices for the separating device of the light buoy, which enable good presetting and ensure provision with this presetting without great effort.

Es ist bekannt, Steigzeitverzögerungen über elektrische Zeitschalter bzw. Uhrwerke durchzuführen. Hierbei ist zwar eine Wiederverwendbarkeit gegeben, aber es muß immer eine Voreinstellung - meist vor dem Werfen der Mine - erfolgen, um die gewünschte Verzögerung zu erzielen. Diese bekannten Anordnungen sind relativ aufwendig.It is known to carry out rising time delays using electrical timers or clockworks. There is reusability here, but there must always be a presetting - usually before the mine is thrown - in order to achieve the desired delay. These known arrangements are relatively complex.

Die Aufgabe der Erfindung ist es, eine einfache Ausbildung von Trenn- oder Auslösevorrichtungen mit Verzögerungsgliedern für Minen zu schaffen, die eine kompakte Ausbildung ermöglichen und günstige Verhältnisse durch eine Voreinstellung sowie Lagerung gewährleisten.The object of the invention is to provide a simple design of separating or triggering devices with delay elements for mines, which enable a compact design and ensure favorable conditions by presetting and storage.

Die Lösung dieser Aufgabe für die Anwendung in Übungsminen erfolgt erfindungsgemaß dadurch, daß die Halteelemente elastisch ausgebildet sind und in verschwenkbare Spannhaken eingreifen, die über einen Stempel derart blockiert sind, daß bei einer Längsverschiebung nach Freigabe eines Steuerweges durch ein wasserlösliches Einkristall als Zeitverzögerungselement die Spannhaken zur Lösung der Halteelemente verschwenkbar sind.This object for use in training mines is achieved according to the invention in that the Retaining elements are designed to be elastic and engage in pivotable tensioning hooks which are blocked by a stamp in such a way that the tensioning hooks can be pivoted to release the holding elements in the event of a longitudinal displacement after release of a control path by a water-soluble single crystal as a time delay element.

Der Vorteil dieser Anordnung besteht darin, daß durch die Verwendung von Einkristallen zur Freigabe der Auslösung der Lichtboje der Einfluß von Luftfeuchtigkeit nicht ausreichend ist, den-Kristall zu lösen, es bedarf vielmehr einer Wasserbenetzung. Somit ist gewährleistet, daß die Auflösezeit des Kristalls erst nach dem Werfen der Mine und dem Eintauchen in das Wasser beginnt. Durch die chemische Reinheit der Kristalle ergibt sich auf einfache Weise eine Reproduzierbarkeit der Löse- bzw. Auslösezeiten. Die große mechanische Festigkeit der Einkristalle bringt es mit sich, daß vor einer Auslösung und Freigabe des Steuerweges für den Stempel fast eine vollständige Auflösung erfolgen muß. Die Einflüsse einer Federkraft spielen somit keine wesentliche Rolle und Frühauslösungen durch Zerbröckeln sind kaum möglich. Dieses wird noch dadurch vermieden, daß durch den Festigungsvorgang von Einkristallen ein schräges Abscheren in den Kristallebenen einzelner Teile nicht vorkommt.The advantage of this arrangement is that through the use of single crystals to release the triggering of the light buoy, the influence of atmospheric moisture is not sufficient to loosen the crystal; rather, water wetting is required. This ensures that the dissolution time of the crystal only begins after the mine has been thrown and immersed in the water. The chemical purity of the crystals results in a simple reproducibility of the dissolution or release times. The great mechanical strength of the single crystals means that almost complete dissolution must take place before the stamp is triggered and the control path is released. The influences of a spring force therefore do not play a significant role and early releases by crumbling are hardly possible. This is further avoided by the fact that, due to the hardening process of single crystals, oblique shearing does not occur in the crystal planes of individual parts.

Zur einfachen Handhabung wird vorgeschlagen, daß das Einkristall als Zylinderstück bzw. Quader ausgebildet ist.For easy handling, it is proposed that the single crystal be designed as a cylinder piece or cuboid.

Um eine gute Gebrauchsfähigkeit unter Berücksichtigung einer wiederholten Bestückung auf einfache Weise zu erzielen, ist vorgesehen, daß das Einkristall durch einen von außen zugänglichen Schraubenverschluß mit Wasserdurchtrittsöffnungen gehalten und in Fortsetzung des Stempels angeordnet ist.In order to achieve good usability in consideration of repeated assembly in a simple manner, it is provided that the single crystal is held by an externally accessible screw closure with water passage openings and is arranged in continuation of the stamp.

Zur Sicherstellung des Auslösevorganges wird weiterhin vorgeschlagen, daß der Stempel in Steuerrichtung durch eine Feder beaufschlagt ist.To ensure the triggering process, it is also proposed that the plunger be acted upon by a spring in the control direction.

Eine günstige Ausbildung wird dadurch geschaffen, daß das Einkristall aus Kaliumbromid (KBr) gebildet ist.A favorable training is created in that the single crystal is formed from potassium bromide (KBr).

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigen:

  • Fig. 1 eine Seitenansicht einer Übungsmine,
  • Fig. 2 eine Trennvorrichtung im vergrösserten Maßstab und
  • Fig. 3 einen Schnitt durch eine Trennvorrichtung.
In the drawings, an embodiment of the invention is shown schematically. Show it:
  • 1 is a side view of a practice mine,
  • Fig. 2 shows a separation device on an enlarged scale and
  • Fig. 3 shows a section through a separating device.

Die dargestellte Übungsmine 1 besteht aus einem Gehäuse 2, das eine durchgehende Aufnahmeöffnung 3 für eine Lichtboje 4 aufweist. Die Lichtboje 4 ist über eine Lichtleine 5 mit der Mine 1 verbunden, wobei die Lichtleine 5 im Ruhezustand auf einer Seiltrommel 6 angeordnet ist. Die Lichtboje 4 ist an beiden Seiten der Aufnahmeöffnung 3 durch einen Haltegurt gehalten. Der Haltegurt 7 ist als elastischer Gummi-Spanngurt ausgebildet und jeweils mit einem Ende in zugeordnete Spannhaken 8 eingehängt, während der Haltegurt 7 mit seinem anderen Ende gehäusefest angeordnet ist. Die Spannhaken 8 sind der eigentlichen Trennvorrichtung 9 zugeordnet, die als kompakte Einheit in einer Nische des Gehäuses 2 aufgenommen wird. Die Spannhaken 8 sind jeweils als zweiarmige Hebel verschwenkbar über einen Bolzen 10 angeordnet und. werden von einem Mechanismus in einer Einstellung blockiert, die im wesentlichen aus einem geführten Stempel 11 besteht und in der Verriegelungsstellung in der Art eines Gegenlagers die Spannhaken 8 in ihrer Position zur Aufnahme der Haltegurte 7 hält. Durch eine Längsverschiebung des Stepels 11 wird die Schwenkbewegung der Spannhaken 8 freigegeben, wobei der eigentliche Schwenkvorgang durch die gespannten, elastischen Haltegurte 7 unterstützt wird. Hierbei werden dann die Haltegurte 7 freigegeben, so daß die Lichtboje 4 sich von der Mine 1 trennen kann.The practice mine 1 shown consists of a housing 2 which has a continuous receiving opening 3 for a light buoy 4. The light buoy 4 is connected to the mine 1 via a light line 5, the light line 5 being arranged on a cable drum 6 in the idle state. The light buoy 4 is held on both sides of the receiving opening 3 by a tether. The holding belt 7 is designed as an elastic rubber tensioning belt and each has one end hooked into associated tensioning hooks 8, while the holding belt 7 is arranged fixed to the housing with its other end. The tensioning hooks 8 are assigned to the actual separating device 9, which as a compact unit in one Niche of the housing 2 is added. The clamping hooks 8 are each arranged as two-armed levers and can be pivoted via a bolt 10. are blocked by a mechanism in a setting that consists essentially of a guided punch 11 and holds the tensioning hooks 8 in their position for receiving the holding straps 7 in the locking position in the manner of a counter bearing. The pivoting movement of the tensioning hooks 8 is released by a longitudinal displacement of the stepel 11, the actual pivoting process being supported by the tensioned, elastic holding belts 7. The straps 7 are then released so that the light buoy 4 can separate from the mine 1.

Die Längsverschiebung des Stempels 11 wird durch ein Einkristall 12 behindert. Dieses Einkristall 12 ist als Verlängerung des Stempels 11 angeordnet und in der Trennvorrichtung 9 über einen Schraubverschluß 13 gehalten. Dieser Schraubverschluß 13 besitzt Wasserdurchtrittsöffnungen 14, um zu ermöglichen, daß das Einkristall 12 von dem umgebenden Wasser umspült und aufgelöst wird. Der Stempel 11 wird zusätzlich von einer Feder 15 beaufschlagt, um die Auslösung sicherzustellen.The longitudinal displacement of the stamp 11 is hindered by a single crystal 12. This single crystal 12 is arranged as an extension of the stamp 11 and held in the separating device 9 by means of a screw closure 13. This screw cap 13 has water passage openings 14 to enable the single crystal 12 to be washed around and dissolved by the surrounding water. The stamp 11 is additionally acted upon by a spring 15 in order to ensure triggering.

Um eine Handhabung entsprechend einer Gefechtsmine durchführen zu können, ist ein Vorstecker 16 für einen herausziehbaren Entsicherungskolben 17 angeordnet, der über einen Betätigungskolben 18 einen Verblockungsbolzen 19 gegenüber dem Stempel 11 löst und damit eine Verschiebung des Stempels 11 ermöglicht.In order to be able to carry out handling in accordance with a battle mine, a pin 16 is arranged for a pull-out unlocking piston 17, which releases an interlocking bolt 19 with respect to the stamp 11 via an actuating piston 18 and thus enables the stamp 11 to be displaced.

Nach der Entsicherung wird die Übungsmine 1 ins Wasser geworfen. Im Wasser löst sich nunmehr das Einkristall 12 auf, bis ein erforderlicher Steuerweg für den Stempel 11 freigegeben wird und die Spannhaken 8 durch die Spannkraft der Haltegurte 7 verschwenkt werden. Hierbei lösen sich die Haltegurte 7 und die Lichtboje 4 wird freigegeben. Durch den Auftrieb gelangt die Lichtboje 4 dann an die Wasseroberfläche.After unlocking, practice mine 1 is thrown into the water. The single crystal 12 now dissolves in the water until a necessary control path for the Stamp 11 is released and the tensioning hooks 8 can be pivoted by the tensioning force of the straps 7. The straps 7 loosen and the light buoy 4 is released. Due to the buoyancy, the light buoy 4 then reaches the water surface.
