Definitions

  • the technical field of the invention is that of devices for the demining of magnetic mines.
  • FR2750204 discloses a deminer device comprising a plurality of cylindrical coils formed of a winding of a conductive wire around a magnetic core.
  • the coils have a ratio length to diameter which is greater than 4 (which makes it possible to ensure a good compromise between volume, mass and efficiency). They are fixed on a beam which is secured to a vehicle and oriented substantially vertically. They are powered by an electric current supplied by a power generator connected to a control box.
  • the patent FR2701105 describes an example of a control electronics for supplying this demining coil.
  • the coils may also interfere with the tank's barrel.
  • demining coils are most often linked to a specific vehicle that is dedicated to this function.
  • the result is a slowdown in field operations.
  • Combat vehicles that encounter a minefield must stop and bring the demining vehicle before they can resume their advance.
  • the vehicles can be in an operational configuration taken under fire from mines dispersed by shells or rockets and intended to stop their progression. The vehicles are then stranded in the field and become very vulnerable to enemy attacks. They can not be released if they do not have demining means of their own.
  • the device according to the invention can be made integral with any type of vehicle without impairing its operational mobility.
  • the subject of the invention is a device for demining magnetic mines, which device comprises at least one magnetic field generating coil connected to at least one power generator which is actuated by a control box, characterized in that the coil is pivotally mounted relative to a box and can occupy at least two positions relative thereto: a folded position in which it is housed inside the box and an extended position in which it leaves the box.
  • the coil may pivot at an angle at least equal to 90 ° to move from its folded position to its deployed position.
  • the device may include at least one actuator for causing the pivoting of the coil and its passage from its folded position to its deployed position.
  • the device may comprise at least one locking device operable remotely and ensuring the locking of the coil in at least one of its positions.
  • the device comprises at least two coils pivotally mounted relative to the box.
  • the device may also include at least one fixed winding surrounding the box and connected to a second power generator.
  • the box may include at least one splinter plate.
  • the splinter plate may be pivotally mounted relative to the box.
  • the box may carry at least one power generator for supplying the coil or coils.
  • a device 1 comprises at least one magnetic field generator coil 2 connected to at least one power generator 3 which is controlled by a control box 4 integral with a vehicle (no represent).
  • the device 1 comprises a box 5 mechanized or welded composite.
  • This box is formed for example of steel sheets. It is substantially parallelepipedic and comprises a front wall 5a, two side walls 5b, 5c, a bottom 5d and a rear wall 5e on which are welded tabs 6 for fixing the box to the vehicle.
  • the 5d background could be omitted.
  • the power generator 3 is here shown attached to the rear wall 5e. It could of course be directly attached to or inside the vehicle, outside the box 5.
  • the spool 2 is fixed on a base 7 which carries a shaft 8 pivotally mounted relative to two bearings 9a, 9b secured respectively to the front walls 5a and 5a rear of the box 5.
  • the bearings 9a and 9b are formed for example by bearings to balls.
  • the shaft 8 materializes an axis 10 relative to which the coil 2 can be rotated.
  • the axis 10 is substantially perpendicular to the front walls 5a and rear 5e of the box and to the axis 11 of the coil 2.
  • Pivoting of the coil 2 can be done at an angle at least equal to 90 °, which allows the coil to move from a folded position, in which its axis 11 is substantially horizontal, to an extended position in which the axis 11 is substantially vertical.
  • This pivoting is controlled by an actuator 12.
  • the actuator is an electric motor that drives a chain or a belt 13 meshing with a grooved portion of the shaft 8 or a gear (not shown).
  • the actuator 12 is implemented from the control unit 4 to which it is connected via a conductive cable 14 which is here connected to the power box 3.
  • Another conductive cable 15 connects the power box 3 to the coil 2 and a conductive cable 16 connects the power box 3 to the control box 4.
  • a locking device 17 is attached to the front wall 5a.
  • This device 17 is formed for example by an electromagnet comprising a rod pushed by a spring. The rod penetrates into a cavity carried by the shaft 8, thus ensuring the locking of the shaft and the coil relative to the housing.
  • At least two cavities are provided, angularly spaced by 90 °, and arranged so as to allow locking of the coil in two angular positions: the folded position and the deployed position.
  • Locking will be done automatically when the coil is moved to one or the other position. To enable the rotation of the spool 2, the unlocking of the device 17 before the actuator 12 is commanded will first be controlled.
  • Unlocking will be controlled remotely from the control box 4.
  • the actuator will be connected to the control box 4 by a not shown conductor cable.
  • Figure 1 shows the coil in its deployed position which is the one adopted to carry out a demining operation.
  • Figure 2 shows the coil 2 in its folded position in which it is housed inside the box 5. In this position the coil is hidden by the box 5. It does not interfere with the vehicle crew and especially disturbs neither the visibility nor the movements of the turret or the cannon.
  • the coil 2 is protected from shocks, projections of stones and splinters of projectiles.
  • the reels are kept folded during the combat or movement phases. Only when a mined area is identified will the vehicle commander order the pivoting of the demining coils to proceed with a clearance operation of the terrain area.
  • Figures 3 and 4 show a second embodiment of the invention.
  • This mode differs from the previous one in that the box 5 encloses two coils 2a, 2b. Each coil may be pivoted from the folded position shown in FIG. 4 to adopt the deployed position shown in FIG.
  • a single power box 3 (controlled by the control unit 4) provides power to the two coils 2a and 2b.
  • Each coil 2a, 2b has a specific locking device 17a, 17b which is actuated from the control box 4.
  • Figure 5 shows a third embodiment of the invention. This mode differs from that of FIGS. 3 and 4 in that the box 5 carries a fixed winding 18 which surrounds the box and which is connected to a second power generator 19.
  • This housing contains the first power generating circuits specific to the coils 2a and 2b and the second power generating circuit specific to the fixed coil 18.
  • Such a fixed coil is described for example by the patent FR2701105.
  • Such an embodiment makes it possible, depending on the operational requirements, to give certain characteristics to the generated signal.
  • FIG. 6 shows an alternative embodiment of the device according to the invention.
  • the box comprises a splinter plate 20 which is fixed to the front wall 5a of the box 5.
  • This splinter plate is made of steel and it protects the coils and the generator during demining operations.
  • the splinter plate 20 is here shown fixed. It could of course be made in the form of a hinged cover to the box 5, lid can fold to close the box when the coils are in their folded position. An appropriate specific motorization (not shown) will then control the opening of the box and the positioning of the splinterguard 20. This drive will be controlled by the control box 4.
  • Splinter plates may also be attached to the side walls 5b and 5c of the box 5.
