Definitions

  • the present invention relates to a remote demining device for mines sensitive to magnetic fields.
  • the energy supply for these demining devices is done by electric generators which are on board minesweepers and by floating cables which are pulled by the dredgers.
  • the excitation coils of electric generators for minesweeping are powered by an electric function generator to produce a demining program.
  • iron bars are located in small motor-driven floats on which there are also generators which produce the current necessary for demining.
  • These systems are described in German patent DE-PS 978 056.
  • the float is constructed of iron like a pressure shell which carries the electric coils.
  • the float carries the generators for propulsion, the magnetic field and the acoustic field.
  • One or more floats are guided by a tanker.
  • the objective which is the basis of the invention is therefore to avoid the disadvantages of known demining systems and to create a demining device for dredging magnetic mines from a distance, which is also suitable for dredging mines with setting heat sensitive to the gradient of the magnetic field, and which allows mission times long enough with a minimum energy supply.
  • this objective is achieved by means of a small mobile body which can be in the form of a torpedo, in which there is a set of permanent magnets which can be in the form of a disc and which can be turned in a direction such that the external magnetic field is maximum during the mine clearance mission, and that this external magnetic field is minimum outside the mission.
  • This movable body can be additionally equipped with a guide section, a sonar, and a propulsion section.
  • the main advantage of the invention is that the manufacture of such a system is not expensive and that knowledge on the manufacture and launching of torpedoes can be used.
  • the mobile torpedo-shaped body has in addition to a guide section and a sonar (4) a demining section (5) in which there is a set of permanent magnets (8) in disc shape.
  • the permanent magnets can be rotated around an axis of rotation (10) which is in a cylindrical shell (7) using an unmanned motor and a mechanism (9) according to the angle longed for.
  • Figure 2b shows the permanent magnet disk in the direction of magnetization.
  • the discs are adjusted so that the direction of the normal to the disc conforms to the axis of the moving body.
  • M representing the magnetization of each disc
  • m representing the magnetic moment of the dipole
  • r the distance
  • the magnetic field of a double dipole is produced by turning one half discs in the opposite direction (see fig. 1).
  • the discs (8) are adjusted so that the normal is perpendicular to the axis of the float.
  • the directions of magnetization of each disc are alternating 180 ° to each other.
  • the direction of normal of the disks with the axis of the moving body can be changed by remote control or by program as required.
  • the moving body can contain a demining program, which is executed. At the end of the program, the moving body automatically returns to the launching boat.
  • the material for the discs it is currently only possible to use materials having a high coercive force to prevent demagnetization of the discs when they are rotated.
  • materials having a high coercive force to prevent demagnetization of the discs when they are rotated.
  • rare earths or combinations comprising rare earths can be used. If ferrite-based materials are used, the clearance distance will be shorter.
  • the known propulsion systems for torpedoes can be used, such as electric motors, diesel engines or others.
  • the mobile body can be equipped with a three-phase motor which is supplied by the boat by a cable.
  • This cable can at the same time have locations for the remote control by an electric wire or an optronic line.
  • the mobile body can be equipped with an acoustic generator which produces an acoustic field simulating the acoustic field of the target, or even it can tow such a generator.
  • the guidance and sonar section may also contain facilities for measuring the magnetic field.
