Definitions

  • 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 swimming cables or an electrically conductive floating cable loop for magnetic mine triggering.
  • Such mine clearance devices serve to render marine mines harmless.
  • 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 noise generator is towed on tensile cables or ropes, the length of the trailing cables or ropes being approximately 300 to 600 meters is.
  • a voltage is applied to the electrode-carrying floating cables or the closed floating cable loop, so that a field is built up between 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.
  • a trailing mine clearing device with an electrically drivable noise generator for acoustic ignition and a cable loop for the magnetic ignition of mines is e.g. made known from DE-C-977 798.
  • 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.
  • several, partly float-like, kites are provided on the cable of the noise generator.
  • 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.
  • 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 protruding 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.
  • 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.
  • both release devices are towed in a straight line behind the mine search boat, so that a clear configuration is created that is easier to deploy and can be retrieved with around 50% less work. 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.
  • the trailing cable When the trailing cable is made from polyarylamide fibers, it is also subject to high tensile stress, for example when the noise is dragged along generator at high speed, only a small tensile elongation, which significantly reduces the friction of the trailing cable on the mechanically less stressed floating cables.
  • 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.
  • 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.
  • Lead wires run from a voltage source at the stern 16 of the boat, forming 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 in such a way 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the dragged-in noise generator 10 with float 11 causes a strong, sudden tensile stress on the tow cable 9 due to its drag-anchor-like effect, which is alleviated by interposing the more elastically stretchable section 13.
  • 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.
  • trailing cable 9 and floating cable 2, 3 are wound together on the wind drum 12, the longitudinally displaceable mounting of the trailing cable 9 relative to the floating cable 2, 3 helping to prevent damage to the cable harness.
  • the strand comprising the trailing cable 9 and the floating cables 2, 3 is let down from the winch drum 12.
  • the mine sweeper tows the mine clearing device, as shown schematically in FIG. 1, behind it.
  • 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 basic amine run over by the mine clearing device as lying directly in front of the noise source formed by the noise generator 10.
  • the mine clearance device is practically indistinguishable from a ship for the base mine and the base mine is triggered.
  • a closed, electrically conductive floating cable loop 20 is provided, which via other cables 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 the flow of current through the floating cable loop 20, a field arises around it, which serves to trigger basic mines that respond to changes in the magnetic field.
  • the position of the floating cable loop 20 can be regulated by means of a steep rope 21 which leads from the floating cable loop 20 to the base plate 8 on the boat stern 16.
  • the feed 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 stern of the boat.
  • 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 mine search boat, so that in this case too, the mines to be triggered are unable to distinguish between the mine clearing device and a ship.
  • 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.
