Description

Die Erfindung betrifft ein nachschleppbares Minenräumgerät mit mindestens einem mechanisch oder elektrisch antreibbarem Geräuscherzeuger zur akustischen Minenauslösung und elektrodentragenden Schwimmkabeln oder einer elektrisch leitfähigen Schwimmkabelschleife zur magnetischen Minenauslösung.The invention relates to a trailing mine clearing device with at least one mechanically or electrically drivable noise generator for acoustic mine triggering and electrode-carrying floating cables or an electrically conductive floating cable loop for magnetic mine triggering.

Solche Minenräumgeräte dienen der Unschädlichmachung von Seeminen. Dabei handelt es sich um Minen mit Magnetzünder, die auf Schwankungen des örtlichen Magnetfeldes reagieren, wie sie bei Annäherung eines hinreichend großen magnetisierbaren Gegenstandes, etwa eines Schiffsrumpfes, an die Mine auftreten; ferner um Minen mit Akustikzünder, die auf die von Schiffsantrieben erzeugten Schallwellen ansprechen, sowie um kombinierte, magnetoakustische Minen, die auf Änderungen des örtlichen Magnetfeldes in Verbindung mit akustischen Signalen ansprechen.Such mine clearance devices serve to render marine mines harmless. These are mines with magnetic detonators that react to fluctuations in the local magnetic field, such as occur when a sufficiently large magnetizable object, such as a ship's hull, approaches the mine; furthermore mines with acoustic detonators, which respond to the sound waves generated by ship propulsion systems, as well as combined magneto-acoustic mines, which respond to changes in the local magnetic field in connection with acoustic signals.

Bei den bekannten Minenräumgeräten der eingangs genannten Art werden von einem Minensuchboot einerseits elektrodentragende Schwimmkabel oder eine geschlossene, elektrisch leitfähige Schwimmkabelschleife, andererseits ein mechanisch oder elektrisch antreibbarer Geräuscherzeuger an zugfesten Kabeln oder Seilen geschleppt, wobei die Länge der Schleppkabel bzw. Seile ungefähr 300 bis 600 Meter beträgt. Zur magnetischen Minenauslösung wird an die elektrodentragenden Schwimmkabel bzw. die geschlossene Schwimmkabelschleife eine Spannung angelegt, so daß sich zwischen den Elektroden - unter Schließung des Stromkreises über das Wasser - oder um die Schwimmkabelschleife herum ein Feld aufbaut. Dieses Feld verändert das von der Grundmine erfaßte örtliche Magnetfeld und löst diese dadurch aus. Zur akustischen Minenauslösung dient der vom Minensuchboot nachgeschleppte Geräuscherzeuger, der üblicherweise mechanisch oder elektrisch angetrieben wird. Er erzeugt ein Klopfgeräusch, das dem Antriebsgeräusch eines Schiffes so weit ähnelt, daß eine akustisch zündbare Mine ausgelöst wird.In the known mine clearing devices of the type mentioned, a mine search boat on the one hand carries electrode-carrying floating cables or a closed, electrically conductive floating cable loop, and on the other hand a mechanically or electrically drivable sound generator on tensile cables or ropes, the length of the trailing cables or ropes being approximately 300 to 600 meters is. For magnetic mine release, a voltage is applied to the electrode-carrying floating cable or the closed floating cable loop, so that between builds up a field around the electrodes - by closing the circuit over the water - or around the floating cable loop. This field changes the local magnetic field detected by the base mine and thereby triggers it. The sound generator, which is dragged by the mine search boat and is usually mechanically or electrically driven, is used to trigger the mine. It generates a knocking sound that is so similar to the propulsion sound of a ship that an acoustically ignitable mine is triggered.

Bei den bekannten Vorrichtungen werden die Vorrichtungen zur magnetischen Minenauslösung, mittels einer Motorwinde aussetz-und einholbar, in gerader Linie hinter dem Minensuchboot geschleppt. Der Geräuscherzeuger wird an einem eigenen Kabel, von einer zweiten Motorwinde aussetz- und einholbar, separat geschleppt, wobei eine seitliche Abscherung von der magnetischen Minenauslösevorrichtung sichergestellt werden muß. Zu diesem Zweck sind am Kabel des Geräuscherzeugers mehrere, zum Teil schwimmerartige, Drachen vorgesehen.In the known devices, the devices for magnetic mine triggering, which can be deployed and retracted by means of a motor winch, are towed in a straight line behind the mine search boat. The noise generator is towed separately on its own cable, which can be deployed and retracted by a second motor winch, with lateral shearing of the magnetic mine release device having to be ensured. For this purpose, several, partly float-like, kites are provided on the cable of the noise generator.

Nachteile dieses bekannten Minenräumgerätes ergeben sich in verschiedener Hinsicht. Zum einen ist die Anordnung mit verschiedenen Kabeln bzw. Seilen und diesen jeweils zugeordneten Motorwinden aufwendig. Das Ausbringen und Einholen der Geräte ist langwierig und insbesondere bei rauher See schwierig. Zur Sicherstellung der parallelen Anordnung im seitlichen Abstand müssen spezielle Scherdrachen am Kabel des Geräuscherzeugers vorgesehen werden. Die Manövrierfähigkeit des Minensuchbootes und die Übersichtlichkeit des Minenräumgerätes lassen zu wünschen übrig. Bei kombinierten Grundminen, die sowohl auf akustische wie auch auf magnetische Einflüsse ansprechen, ist bei dem bekannten Minenräumgerät durch den seitlichen Abstand zwischen Geräuscherzeuger und Feldquelle eine sichere Auslösung nicht gewährleistet, da moderne kombinierte Grundminen aufgrund dieses Abstandes bereits zwischen Schiffen und entsprechenden Minenräumgeräten unterscheiden können.Disadvantages of this known mine clearing device arise in various respects. On the one hand, the arrangement with different cables or ropes and associated motor winches is complex. The deployment and retrieval of the devices is lengthy and difficult, especially in rough seas. To ensure parallel arrangement at a lateral distance, special shear kites must be provided on the cable of the noise generator. The maneuverability of the minesweeper and the clarity of the mine clearance device leave something to be desired. In the case of combined landmines that respond to both acoustic and magnetic influences, safe triggering is not guaranteed in the known mine clearance device due to the lateral distance between the noise generator and the field source, because modern combined base mines can already distinguish between ships and corresponding mine clearance devices due to this distance.

Aufgabe der Erfindung ist es daher, ein Minenräumgerät der eingangs genannten Art zu schaffen, das bei vereinfachtem Aufbau eine zuverlässige Minenauslösung ermöglicht.The object of the invention is therefore to provide a mine clearing device of the type mentioned, which enables reliable mine release with a simplified structure.

Zur Lösung dieser Aufgabe ist das Minenräumgerät der eingangs genannten Art erfindungsgemäß dadurch gekennzeichnet, daß mindestens die bootsnahen Abschnitte des Schleppkabels des Geräuscherzeugers und der Schwimmkabel strangartig gemeinsam verlaufen, das Schleppkabel eine über das bootsferne Ende der Schwimmkabel hinausragende Länge aufweist, und das Schleppkabel und die Schwimmkabel zueinander begrenzt längsverschiebbar geführt sind.To solve this problem, the mine clearing device of the type mentioned is characterized according to the invention in that at least the boat-near sections of the trailing cable of the noise generator and the floating cable run together like a string, the trailing cable has a length that projects beyond the end of the floating cable remote from the boat, and the trailing cable and the floating cable limited to each other are guided longitudinally.

Bei der erfindungsgemäßen Konfiguration des Minenräumgeräts sind die elektrodentragenden Schwimmkabel bzw. die bootsnahen Zuleitungsabschnitte zur Schwimmkabelschleife einerseits, das Schleppkabel des Geräuscherzeugers andererseits, strangartig zusammengefaßt. Am bootsfernen Ende des sich über die Schwimmkabel hinaus erstreckenden Schleppkabels hängt der Geräuscherzeuger. So werden beide Auslösevorrichtungen in gerader Linie hinter dem Minensuchboot geschleppt, so daß eine übersichtliche Konfiguration entsteht, die einfacher und mit etwa 50% Arbeitsersparnis ausbringbar und einholbar ist. Teure und die Handhabung erschwerende Scherdrachen sind nicht mehr nötig. Feldquelle und Geräuscherzeuger liegen dicht hintereinander und entsprechen so in praktisch idealer Weise den Verhältnissen bei den von ihnen nachgeahmten Schiffen. Damit ist sichergestellt, daß auch eine moderne Grundmine nicht zwischen dem Minenräumgerät und einem tatsächlichen Schiff unterscheiden kann. Zum Ausbringen und Einholen des Minenräumgeräts ist nur noch eine Motorwinde notwendig. Das Minensuchboot ist bei ausgebrachtem Minenräumgerät wesentlich manövrierfähiger. Durch die zueinander begrenzt längs verschiebbare Führung von Schleppkabel und Schwimmkabeln wird unter anderem vermieden, daß die Schwimmkabel die wesentlich stärkeren Änderungen unterworfene mechanische Beanspruchung des Schleppkabels mittragen müssen.In the configuration of the mine clearing device according to the invention, the electrode-carrying floating cables or the boat-near feeder sections to the floating cable loop, on the one hand, and the trailing cable of the noise generator, on the other hand, are combined like a strand. The noise generator hangs at the end of the trailing cable that extends beyond the floating cable. So both release devices are towed in a straight line behind the mine search boat, so that a clear configuration is created, which is easier to deploy and can be obtained with about 50% labor savings. Expensive and difficult to use scissor kites are no longer necessary. The field source and noise generator are located close to one another and thus correspond in a practically ideal way to the conditions in the ships they mimicked. This ensures that even a modern base mine cannot differentiate between the mine clearance device and an actual ship. Only one motor winch is required to bring out and bring in the demining device. The mine sweeper is much more maneuverable when the mine clearing device is deployed. The mutually longitudinally displaceable guidance of trailing cables and floating cables prevents, among other things, the floating cables from undergoing the much stronger changes mechanical stress on the trailing cable.

Vorteilhafte weitere Ausgestaltungen des Minenräumgerätes sind in den Unteransprüchen 2 bis 6 beschrieben.Advantageous further refinements of the mine clearing device are described in subclaims 2 to 6.

Bei Fertigung des Schleppkabels aus Polyarylamidfasern unterliegt dieses auch unter hoher Zugbeanspruchung, etwa bei Nachschleppen des Geräuscherzeugers bei Schnellfahrt, einer nur geringen Zugdehnung, was die Reibung des Schleppkabels an den mechanisch nicht so stark beanspruchten Schwimmkabeln deutlich vermindert. Eine elastisch federnde Ankopplung des Geräuscherzeugers an das Schleppkabel kann durch Zwischenschaltung eines Abschnitts aus stärker elastisch dehnbarem Werkstoff zwischen dem Polyarylamid-Kabel und dem Geräuscherzeuger erreicht werden. Zum Aufwickeln des Minenräumgerätes auf eine einzige Windentrommel ist es vorteilhaft, die bootsnahen Enden des Schleppkabels und des Zugseils der Schwimmkabel bzw. deren Ziehstrümpfen mechanisch miteinander zu verbinden.When the trailing cable is made from polyarylamide fibers, it is subject to only a slight elongation under high tensile loads, such as when the noise generator is being dragged during high-speed travel, which significantly reduces the friction of the trailing cable on the floating cables, which are not mechanically stressed. An elastically resilient coupling of the sound generator to the trailing cable can be achieved by interposing a section made of more elastically stretchable material between the polyarylamide cable and the sound generator. To wind up the mine clearing device on a single winch drum, it is advantageous to mechanically connect the ends of the trailing cable and the pull cable of the floating cable or their pulling stockings near the boat to one another.

Im folgenden werden bevorzugte Ausführungsformen des Minenräumgeräts anhand der beigefügten Zeichnungen weiter erläutert. Es zeigen:

  • Fig. 1 ein erfindungsgemäßes Minenräumgerät mit elektrodentragenden Schwimmkabeln,
  • Fig. 2 ein weiteres Minenräumgerät mit Schwimmkabelschleife und
  • Fig. 3 eine schematische Darstellung eines Querbundes.
Preferred embodiments of the mine clearing device are explained in more detail below with reference to the accompanying drawings. Show it:
  • 1 is a mine clearing device according to the invention with electrode-carrying swimming cables,
  • Fig. 2 shows another mine clearing device with floating cable loop and
  • Fig. 3 is a schematic representation of a cross waistband.

Das in Fig. 1 gezeigte nachschleppbare Minenräumgerät 1 umfaßt zwei Schwimmkabel 2,3 unterschiedlicher Länge, die in ihren bootsfernen Endbereichen mit Elektroden 4, 5 versehen sind. Die Kabel sind durch Kork- und/oder Schaumstoffeinlagen schwimmfähig gemacht. Von einer Spannungsquelle am Bootsheck 16 verlaufen Leitungsdrähte unter Bildung eines Vorlaufs 15 durch das Innere der Schwimmkabel 2, 3 zu den Elektroden 4, 5. Die Leitungsdrähte sind dabei im bootnahen Bereich so umeinandergewunden, daß die Bildung eines minenauslösenden Felds in Bootsnähe vermieden wird. Der Vorlauf 15 ist mit Ziehstrümpfen 6 versehen, an denen Zugseile 7 angreifen, die im Schleppbetrieb mit einer Grundplatte 8 auf dem Bootsheck 16 verbunden und zum Einholen auf die Windentrommel 12 aufgewickelt werden.The towable mine clearing device 1 shown in FIG. 1 comprises two floating cables 2, 3 of different lengths, which are provided with electrodes 4, 5 in their end regions remote from the boat. The cables are made buoyant by cork and / or foam inserts. From a voltage source on the boat stern 16, lead wires form a lead 15 through the interior of the floating cables 2, 3 to the electrodes 4, 5. The lead wires are wound around one another in the area near the boat so that the Formation of a mine-triggering field near the boat is avoided. The lead 15 is provided with pulling stockings 6, on which pull cables 7 engage, which are connected to a base plate 8 on the boat stern 16 in towing operation and are wound up on the winch drum 12 for catching up.

Mit den Zugseilen 7 ist ein Schleppkabel 9 verbunden, das sich im bootnahen Bereich strangartig gemeinsam mit dem Vorlauf 15 und den Schwimmkabeln 2, 3 erstreckt. Dabei ist das Schleppkabel 9 diesen gegenüber längsverschiebbar von den Schwimmkabeln 2, 3 bzw. deren Ziehstrumpf 6 umwunden und verläuft so nach Art einer Kabelseele im Stranginneren. Im bootsfernen Bereich, in welchem die Schwimmkabel 2, 3 nicht mehr um das Schleppkabel 9 herumgewunden sind, sondern frei etwa parallel nebeneinander schwimmen, dienen Querbünde 14 zum Zusammenhalten von Schleppkabel 9 und Schwimmkabeln 2, 3. Dabei wird das Schleppkabel 9 in am Querbund 14 befestigten Führungsrohren 14a reibungsarm längsverschieblich geführt. Die Schwimmkabel 2, 3 werden durch die Querbünde 14 so lose gehalten, daß sie zueinander begrenzt längsverschiebbar bleiben. Anstatt teilweise von den Schwimmkabeln 2, 3 umwunden zu sein, kann das Schleppkabel 9 auch auf seiner ganzer Länge neben den Schwimmkabeln 2, 3 verlaufen und ist dann nur durch Querbünde 14 längsverschiebbar an den Schwimmkabeln 2, 3 gehaltert.A trailing cable 9 is connected to the traction ropes 7 and extends in the area near the boat in the form of a strand together with the lead 15 and the floating cables 2, 3. In this case, the trailing cable 9 is wound longitudinally displaceably by the floating cables 2, 3 or their pulling stocking 6 and thus runs in the manner of a cable core inside the strand. In the area away from the boat, in which the floating cables 2, 3 are no longer wound around the trailing cable 9, but float freely approximately parallel to one another, transverse frets 14 serve to hold the trailing cable 9 and floating cables 2, 3 together attached guide tubes 14a guided longitudinally with low friction. The floating cables 2, 3 are held so loosely by the transverse frets 14 that they remain longitudinally displaceable to a limited extent. Instead of being partially surrounded by the swimming cables 2, 3, the trailing cable 9 can also run along its entire length next to the swimming cables 2, 3 and is then only longitudinally displaceably supported on the swimming cables 2, 3 by transverse collars 14.

Das Schleppkabel 9 besteht zwischen der Grundplatte 8 und dem bootsfernen Ende des längeren Schwimmkabels 2 im wesentlichen aus Polyarylamidfasern (Kevlar) und weist daher auch unter hoher mechanischer Beanspruchung nur eine sehr geringe Zugdehnung auf. Hinter dem bootsfernen Ende des längeren Schwimmkabels 2 schließt sich an den im wesentlichen aus Polyarylamidfasern bestehenden Teil des Schleppkabels 9 ein Abschnitt 13 aus stärker elastisch dehnbarem Werkstoff an. Dieser dient zur elastischen Abfederung des an seinem bootsfernen Ende angehängten Geräuscherzeugers 10, der von einem Schwimmer 11 getragen wird. Bei hoher Beschleunigung des Minensuchbootes bewirkt der nachgeschleppte Geräuscherzeuger 10 mit Schwimmer 11 durch seine schleppankerartige Wirkung eine starke, plötzliche Zugbeanspruchung des Schleppkabels 9, die durch Zwischenschalten des stärker elastisch dehnbaren Abschnitts 13 abgemildert wird.The trailing cable 9 consists essentially of polyarylamide fibers (Kevlar) between the base plate 8 and the end of the longer floating cable 2 remote from the boat and therefore has only a very low tensile elongation even under high mechanical stress. Behind the end of the longer floating cable 2 remote from the boat, a section 13 of a more elastically stretchable material adjoins the part of the trailing cable 9 which essentially consists of polyarylamide fibers. This serves for the elastic cushioning of the sound generator 10 attached to its end remote from the boat, which is carried by a float 11. At high acceleration of the minesweeper, the dragged-in noise generator 10 with float 11 causes it Drag anchor-like effect a strong, sudden tensile stress on the trailing cable 9, which is mitigated by interposing the more elastically stretchable section 13.

Am Bootsheck 16 ist eine Windentrommel 12 vorgesehen, die zum Aufwinden und Wiederablassen des gesamten Minenräumgerätes dient. Die bootsnahen Enden des Schleppkabels 9 und des Zugseils 7 der Schwimmkabel 2, 3 sind miteinander verbunden. Zum Einholen des Minenräumgerätes werden Schleppkabel 9 und Schwimmkabel 2, 3 gemeinsam auf die Windentrommel 12 aufgewunden, wobei die längsverschiebbare Halterung des Schleppkabels 9 gegenüber den Schwimmkabeln 2, 3 dazu beiträgt, daß Beschädigungen des Kabelstrangs vermieden werden. Entsprechend wird beim Ausbringen des Minenräumgerätes der das Schleppkabel 9 und die Schwimmkabel 2, 3 umfassende Strang von der Windentrommel 12 abgelassen.A winch drum 12 is provided on the boat stern 16 and is used to wind up and lower the entire mine clearing device. The boat-near ends of the tow cable 9 and the pull rope 7 of the floating cables 2, 3 are connected to one another. For recovering the M inenräumgerätes trailing cable 9 and float cables 2, 3 are wound together on the winch drum 12, wherein the longitudinally displaceable mounting of the towing cable 9 with respect to the floating cables 2, 3 helps prevent damage to the wire harness. Correspondingly, when the mine clearing device is deployed, the strand comprising the trailing cable 9 and the floating cables 2, 3 is let down from the winch drum 12.

Im Räumbetrieb schleppt das Minensuchboot das Minenräumgerät, etwa wie in Fig. 1 schematisch gezeigt, hinter sich her. Die von der Spannungsquelle am Bootsheck 16 über den Vorlauf 15 an die Elektroden 4, 5 der Schwimmkabel 2, 3 angelegte Spannung erzeugt ein von einer von dem Minenräumgerät überfahrenen Grundmine als unmittelbar vor der vom Geräuscherzeuger 10 gebildeten Geräuschquelle liegend erfaßtes Feld. Dadurch ist für die Grundmine das Minenräumgerät von einem Schiff praktisch nicht mehr unterscheidbar und die Grundmine wird ausgelöst.In the clearing operation, the mine sweeper tows the mine clearing device behind, as shown schematically in FIG. 1. The voltage applied to the electrodes 4, 5 of the floating cables 2, 3 by the voltage source at the stern 16 of the boat via the lead 15 generates a field detected by a mine mine run over by the mine clearing device as lying directly in front of the noise source formed by the noise generator 10. As a result, the mine clearance device is practically indistinguishable from a ship for the base mine and the base mine is triggered.

Bei der in Fig. 2 gezeigten abgewandelten Ausführungsform, in der gleiche Bezugszeichen gleiche Teile wie in Fig. 1 angeben, ist statt zweier elektrodentragender Schwimmkabel eine geschlossene, elektrisch leitfähige Schwimmkabelschleife 20 vorgesehen, die über ansonsten den bereits anhand Fig. 1 beschriebenen Schwimmkabeln entsprechende Zuleitungen 2 mit einer Spannungsquelle am Bootsheck 16 verbunden ist. Aufgrund Stromflusses durch die Schwimmkabelschleife 20 entsteht um diese herum ein Feld, das der Auslösung auf Magnetfeldänderungen ansprechender Grundminen dient. Die Stellung der Schwimmkabelschleife 20 ist mittels eines Stellseils 21 regulierbar, das von der Schwimmkabelschleife 20 zur Grundplatte 8 auf dem Bootsheck 16 führt. Die Zuleitungen 2 zur Schwimmkabelschleife 20 werden durch entsprechende Maßnahmen, wie beispielhaft bereits anhand Fig. 1 beschrieben, dagegen geschützt, daß ein minenauslösendes Feld zu nahe am Bootsheck entsteht.In the modified embodiment shown in FIG. 2, in which the same reference numerals indicate the same parts as in FIG. 1, instead of two electrode-carrying floating cables, a closed, electrically conductive floating cable loop 20 is provided, which via other lines corresponding to the floating cables already described with reference to FIG. 1 2 is connected to a voltage source on the boat stern 16. Due to current flow through the floating cable loop 20, a field arises around it, which triggers changes in the magnetic field appealing basic mines. The position of the floating cable loop 20 can be regulated by means of an adjusting rope 21 which leads from the floating cable loop 20 to the base plate 8 on the boat stern 16. The supply lines 2 to the floating cable loop 20 are protected by appropriate measures, as already described by way of example with reference to FIG. 1, against the occurrence of a mine-triggering field too close to the boat's stern.

Auch bei dieser abgewandelten Ausführungsform liegt das Feld zur Auslösung von auf Magnetfeldänderungen ansprechenden Minen in Fahrtrichtung des Minensuchbootes direkt vor dem Geräuscherzeuger 10, so daß auch in diesem Falle die auszulösenden Minen zur Unterscheidung zwischen dem Minenräumgerät und einem Schiff außer Stande sind.In this modified embodiment, too, the field for triggering mines that respond to magnetic field changes is located directly in front of the noise generator 10 in the direction of travel of the minesweeper, so that in this case too, the mines to be triggered are unable to distinguish between the mine clearing device and a ship.

Ausbringen und Einholen des Minenräumgerätes verlaufen wie bei der an Hand Fig. 1 beschriebenen Ausführungsform mittels einer einzigen Windentrommel 12 am Bootsheck 16.The mine clearing device is brought out and brought in as in the embodiment described with reference to FIG. 1 by means of a single winch drum 12 on the boat stern 16.
