Definitions

  • the invention relates to an explosive cutter for mine anchorages according to the preamble of claim 1.
  • Detachers for mine anchorages are attached to the shell of an underwater vehicle and are brought with it to a mine anchorage of a located anchor mine to be mechanically attached to the mine anchorage. Disconnected from the underwater vehicle, the explosive cutter cuts the anchor rope by means of an explosive charge, in particular an elongated shaped charge. In known explosive cutters, however, further vectorial forces are required for detaching from the underwater vehicle, for example the underwater vehicle has to be maneuvered by reversing to release the explosive cutter by reversing or using its buoyancy.
  • the object of the invention is to provide an explosive cutter according to the preamble of claim 1, which can be forcibly released from the mine anchorage and clamped to the latter when the underwater vehicle moves forward.
  • Fig. 1 shows schematically the attachment of an explosive cutter to the anchor rope of an anchor mine.
  • Fig. 2 shows a high-speed cutter in plan view.
  • Fig. 3 shows the detonator of Fig. 2 with the cover removed.
  • Fig. 4 shows the explosive cutter of Fig. 2 in perspective.
  • 5a to 5e show in different stages the attachment and detachment of the explosive cutter of FIG. 2 to an underwater vehicle.
  • an anchor mine 2 which is attached to an anchor chair 4 via an anchor rope 3, is located by a minesweeper 1, and an underwater vehicle 5, which is provided with one or two explosive cutters 6, is sent out to install an explosive cutter 6 on the anchor rope 3, and after return or sufficient removal of the underwater vehicle 5 from the anchor mine 2, the explosive cutter 6 is ignited via coded sonar signals emitted by the minesweeper 1, so that the anchor rope 3 is cut and the anchor mine 2 rises to the water surface, where it can be destroyed from minesweeper 1.
  • the explosive cutter 6 comprises a housing 7 with a (here multi-part) cover 8, the housing 7 and cover 8 being designed in such a way that the explosive cutter 6 together with the components accommodated therein, which i.a. a cutting charge 9, a detonator 10, a transfer charge 11, a pyrotechnic charge 12 and trigger electronics 13, are essentially buoyancy-neutral.
  • a lightweight plastic such as rigid polyurethane foam is particularly suitable as the material for the housing 7 and the cover 8, the housing 7 and cover 8 being connected by a permanently elastic adhesive.
  • the housing 7 has a good hydrodynamic shape and can be built with relatively small dimensions.
  • the housing 7 is provided with a longer, wedge-shaped, separately manufactured and attached to the housing 7 inlet rail 14 and a shorter, separately or integrally formed with the housing 7 inlet rail 15, which form an inlet mouth 16 for the anchor rope 3.
  • the cover 8 has a guide 17 for a slide 18 which extends in the direction of travel of the underwater vehicle 5 and thus in the direction of entry of the anchor rope 3 into the inlet mouth 16, which is guided by a compression spring 18a in the direction of the inlet rails 15, 16 and thus against the direction of entry of an anchor rope 3 spring-loaded into the inlet mouth 16 is.
  • the slide 18 At the end adjacent to the inlet mouth 16, the slide 18 has a plate 19 which extends into the inlet mouth 17 and bridges the width of the inlet mouth 16.
  • the slider 18 has two locking recesses 20, which cooperate with corresponding, angled locking cams 21 which are wedge-shaped towards the free end on an adapter plate 22.
  • the adapter plate 22 is attached to the underwater vehicle 5 and is provided with a stop 23.
  • the locking recesses 20 are provided at the end facing the infeed rails 15, 16 with an incline ramp 24 rising from the outside inwards and at the other end with an undercut 25, so that the associated locking cam 21 can be received from the outside in the locking recess 20 if under System of the explosive cutter 6 at the stop 23 of the slide 18 is moved against its spring preload, cf. Fig. 5c.
  • the locking cam 21 is pulled along the ramp 24 into the locking recess 20 and the spring bias of the slide 18 holds the cutter 6 on the adapter plate 22 and thus on the underwater vehicle 5, cf. Fig. 5d.
  • the cover 8 has a recess 26 in which a curved clamping lever 27 is arranged.
  • the clamping lever 27 is secured at its free, approximately hook-shaped end by a locking pin 28 to be unlocked manually before the blasting cutter 6 is used, and is acted upon by a torsion spring 29 at its other end.
  • the clamping lever 27 is held on the outside of the housing 7 by means of a bracket 30 and a locking screw 30a, which also forms the pivot axis of the clamping lever 27.
  • the slider 18 has a nose 31 which the clamping lever 27th holds locked as long as the slide 18 is held by its spring bias in its locked position to the adapter plate 22. However, if the slider 18 is pressed against the spring pretension by an anchor rope 3, its nose 31 is displaced with the slider 18, which, when it reaches a recess 32 provided in the clamping lever 27, releases the clamping lever 27 so that it under the action of the torsion spring 29 is pivoted parallel to the outside of the cover 8 into a position in which it comprises the anchor rope 3 and closes the inlet mouth 17 from its entry side.
  • a locking lever 33 spring-loaded against the slide 18 can be provided on the cover 8, which, for example, is reached when it is reached the end position of the slider 18 falls into a recess 34 provided laterally in the slider 18 and thus holds the slider 18 in its retracted position against the spring preload.
  • the locking lever 33 can, as shown, in turn be released by pivoting the clamping lever 27.
  • the clamping lever 27 may have several ratchet teeth on the underside, which cooperate with a locking element 35, so that the clamping lever 27 cannot be inadvertently pivoted back from its position closing the insertion mouth 17, for example by the anchor rope 3.
  • the clamping lever 27 pivots until the anchor rope 3 is clamped between it and the plate 19.
  • the pivoting of the clamping lever 27 also serves to effect the actuation of a switch for switching on the power supply for the trigger electronics 13.
  • the locking pin 28 can be arranged spring-biased in the direction of the clamping lever 27 in the housing 7 and secured by a manually removable pin pin 36, the Safety pin 28 in the position securing the clamping lever 27 protrudes into an opening of the latter. After manual removal of the pre-pin 35, the locking pin 28 can be pressed inward by the clamping lever 27 when released against the spring preload into the housing 7 and the switch for the trigger electronics 13 can thereby be actuated.
  • the pin pin 36 can have a circumferential throat, which receives the facing free end of the locking pin 28.
  • the locking pin 28 is moved in the axial direction, so that arranged on the locking ring 28 for sealing purposes, possibly O-rings that have become dry due to longer storage are inevitably moved and then no longer impair a movement of the locking pin 28 under its spring preload.
  • the detonator 6 After detaching the detonator 6 from the underwater vehicle 5, the latter moves away from the danger area of the former, after which, by sending coded sonar signals after a predetermined dead time of, for example, 15 minutes, the pyrotechnic charge 12 is activated, thereby securing the detonator 10, its first fuse a predetermined water depth of 5 m, for example, releases the ignition of the cutting charge 9.
  • the locking cams 21 can also be arranged on the slide 18 and the locking recesses 20 on the adapter plate 22 or on the underwater vehicle 5.
  • the mechanically movable parts are expediently at least predominantly made of aluminum.
