Definitions

  • the present invention relates to an apparatus and a method for the disposal of an unexploded warfare agent which lies underwater, as for example in FIG EP3007966 B described.
  • unexploded ordnance or unexploded ordinance, UXO for short, for example aerial bombs, large-caliber grenades, torpedoes, sea mines, depth charges or other bulky weapons.
  • a method with a device to minimize the risk to people and material and to reduce costs is, for example, in the EP 2 415 660 A1 disclosed.
  • an explosive charge that is as light as possible is attached and fixed to a UXO in question in a munitions clearance device instead of by a diver using an unmanned, remote-controlled underwater vehicle, or ROV for short.
  • the ordnance disposal device comprises a radio buoy which is detachable from the ordnance disposal device and then rises to the surface of the water and is connected to the explosive charge via a line.
  • an explosive charge should be as small as possible and thus be able to be positioned safely and precisely on the UXO even with a small ROV.
  • the ordnance disposal device also has a holding device which can be designed in the form of an electromagnet, a vacuum device and / or a clamping device.
  • the present invention has the aim of developing a known device in order to make a corresponding method even more efficient while opening up further cost and efficiency potentials with increased safety and simplified handling.
  • the ordnance disposal device has a device by which the buoy can be detached from the ordnance disposal device by the ROV, this device comprising a spring-elastic secured locking element, in particular in the form of a spring pin, in the area of the frame which is removable by the ROV.
  • This reliable triggering of the buoy from the ordnance disposal device has thus been solved in a very advantageous manner as a known problem according to the invention.
  • Spring pins are known in different designs as resiliently secured locking elements made of metal or plastic and are characterized as mechanically durable and reliably detachable passive connecting elements even under the very rough conditions at sea at a low price. Actuation by an ROV, which must be available to transport and position the ordnance disposal device on the UXO anyway, reduces the need for separately controlled actuators.
  • a method forms a solution to the above-mentioned object, the method being via a transporting and positioning of an explosive ordnance disposal device by a diving robot or ROV using a frame with the explosive charge on the ordnance (UXO), the activation of a triggering device for releasing a fixation between a buoy and the frame of the ordnance disposal device by pulling off a resiliently secured locking element in particular in the form of a spring clip in the area of the frame by the diving robot.
  • a solution according to the invention thus has the advantage of a simple design of the buoy, which now essentially only represents a buoyancy body and does not comprise any electrical functional parts.

  • the spring pin for releasing the buoy is connected to the ROV, in particular via a loop.
  • the buoy is connected to a detonator in the explosive charge of the ordnance disposal device via a shock tube as a line, the buoy carrying an additional section of the shock tube.
  • a length of this additional section of the shock tube is preferably dimensioned in such a way that a predetermined minimum distance is thereby established between an ignition device and a detonating demolition expert and the buoy on the water surface.
  • the additional section of the shock tube is temporarily stored on a means on the buoy.
  • the means is designed as a coil which can be detached from the buoy and on which the additional section of the shock tube is wound. This means that the agent can be easily and safely removed from the buoy even at sea
  • the buoy carries an antenna which is connected to a radio ignition device on the explosive charge via an antenna line.
  • the buoy itself thus remains a purely passive component; a coded radio signal is only converted in the radio ignition device connected via the antenna line to trigger the explosive charge.
  • Potentially dangerous and / or safety-relevant components are moved to an area of the detonator and destroyed in the course of the detonation.
  • the buoy is connected to the ordnance disposal device by a line to fix the position purely as a marker and warning sign on the water surface and the explosive charge is connected separately to an underwater transponder via an approximately 100m long shock tube, which is Positioning of the ordnance disposal device for depositing by the ROV outside a defined area around the UXO on the surface of the seabed and for ignition via an underwater transmitter of a control and supply ship.
  • Said defined area around the UXO can e.g. defined by a bubble curtain as protection of the environment from the acoustic effects of a blast.
  • the ordnance disposal device has a device on its frame through which the buoy can be removed after it has been removed a spring pin through which the ROV can be released from the ordnance disposal device in order to be able to rise freely to the surface of the water.

  • This frame forms a compact component that can preferably be made of steel as a welded construction.
  • the mass of the ordnance disposal device is sufficient with the weight effective under water without further fixation means for a secure positioning on the UXO.
  • this framework forms a basis for a modular system that can be equipped with alternatives depending on the national blasting regulations, but also weather-related peculiarities of a particular application, as described below with reference to alternative exemplary embodiments.

Connections of the shock tube 3 with feed lines (not shown) for at least one detonator in the explosive 4 are also fixed in an easily producible manner on the sheet metal 9 by means of cable ties.
  • This roughly sketched structure makes it possible to use a prefabricated and explosive-free intermediate stored base within a short time, even by a single specialist with appropriate fireworks approvals, with a buoy 2 and at least one attached shock-tube 3 with associated detonators, and explosives 4 to a ready-to-use ordnance disposal device 1 to be completed for an upcoming assignment.

  • a strain relief in the form of a nylon rope is guided parallel to the shock tube 3 and connected to this at intervals of approx. 2 m, preferably by means of adhesives produced at no temperature, in particular using a seawater-proof assembly tape.
  • This strain relief is on the one hand on the frame 5, for example in the area of the receptacle 6, and on the other hand is fixed on the buoy 2, for example by knotting the respective ends with tensile strength.
  • a second section of the shock tube 3 with a length l is arranged within the inner cylinder 12 in such a way that it rises together with the buoy 2 to the water surface WO after a triggering device 14 (not visible here) has been activated.
  • a recess A on the inner cylinder 12 enables the shock-tube 3 to pass over safely with strain relief from the outer cylinder 13 to fix the shock-tube 3 on the buoy 2, as best shown in the illustrations in FIG Figures 4 and 5 can be seen.
  • Further measures for strain relief of the shock tube 3 are known to the person skilled in the art, for example in the form of free loops, and are also used if necessary in order to limit a tensile force on the shock tube 3.

  • a dashed handle 15 with an upper end stop is here in the form of a plate on which the buoy 2 is fixed, in the area of the triggering device 14 at a free end E so that the buoy 2 with the handle 15 is only released by releasing it Fixation up to the water surface WO can rise freely and carry corresponding sections of the shock tube 3.
  • FIG. 4 is a perspective top view of a basic kit of the device 1 according to the preceding figures, i.e. without shock tube 3, detonator and explosive 4.
  • the free end E of the T-shaped grip element 15 is formed by a recess of the buoy 2 running along a central axis pushed through to the stop on a plate.
  • the grip element 15 has several through bores at the free end E, a first of which is occupied by a bolt 17 for securing the buoy 2 on the grip element 15, the bolt 17 having an eyelet 17a for fixing the strain relief of the shock tube 3 .

  • the spring pin 20 is additionally connected to a loop 20a. If this loop 20a is fixed to the ROV, the spring pin 20 is automatically pulled off after the ordnance disposal device 1 is positioned when the ROV is removed. Additional search and positioning maneuvers of the ROV and / or a gripper of the ROV after the spring pin 20 are thus avoided while saving energy and process time.
  • the fixation of the buoy 2 on the base plate 11 of the frame 5 is thus always reliably released and the buoy 2 then rises essentially vertically to the water surface WO when the ROV moves away from the ordnance disposal device 1 essentially horizontally. In principle, this prevents the ROV from getting caught in the shock tube 3 or damaging it.
  • FIG. 3 shows a matching of the inner diameter D of the outer cylinder 13 to a maximum diameter of the buoy 2 and the inner diameter d of the inner cylinder 12 to the coil 16 as an effective measure to facilitate assembly of the release device 14.

  • Figure 5 shows a side view of the buoy 2 with the spool reel 16 attached.
  • the buoy 2 Since the buoy 2 is a stand element known from fishing, such as is used as a float on nets, this buoy 2 has a central axis continuous recess.

Beyond a receptacle for this bolt 17, the grip element 15 is extended in such a way that the coil 16 can be pushed onto it and secured by a spring clip 18. The coil 16 can thus be removed from the T-shaped grip element 15 by loosening the spring clip 18 by hand.
  • Figure 6 shows as a sketch a sequence of a method for UXO disposal using the ordnance disposal device 1 Figure 1 .

  • the locking bar 20 of the release device 14 is automatically after the ordnance disposal device 1 has been set down and the ROV has been released actuated and withdrawn.
  • the buoy 2 thus rises to the water surface WO, a possibly prevailing ocean current MS being able to cause a slight drift with respect to the position of the UXO on the ocean floor BO.
  • the ROV moves away along the dashed arrow in a direction which is essentially perpendicular to that of the shock tube 3 rising from the buoy 2. Any catching of the ROV in the shock tube 3 is therefore excluded as far as possible.

The buoy 2 then remains in the water while the section of the shock tube 3 with the length l wound on the spool 16 is unwound. In this case, a demolition expert in a boat 22 moves away from the buoy 2 by a distance essentially corresponding to the length l.

  • the handle 15 of the buoy 2 only the rest of the strain relief and the shock tube 3 have to be removed from the eyelet 17a. All other components are lost as a result of the blast so that no further search under water has to be carried out after confirmation that the UXO has been blasted.
  • the basic kit of the ordnance disposal device 1 described above can be separated and temporarily stored with comparatively low safety standards under the captive and seawater-proof pre-assembly outlined above of all individual parts and free of any kind of explosives, since the individual explosives themselves prior to assembly poses very little danger.
