Definitions

  • the invention relates to a method for clearing a minefield with a pressure-sensitive ignition trigger having mines that are subjected to a triggering pressure load for clearing, and to a throwing device for performing the method.
  • clearing conductors are used to detonate the mines of a mine field, which are designed in the form of rope ladders whose rungs contain the explosive charges.
  • rockets are used which discharge the clearing conductors, which are leporello-like in a transport container, from the transport container and pull them over the minefield.
  • a disadvantage of these known clearing carpets or clearing conductors is the use of explosive charges to detonate the mines to be cleared, which, at least in the case of pressure-sensitive triggers, do not require such a detonation. It would therefore be advantageous only to apply such mines with a trigger pressure sufficient for the ignition, which can be applied over corresponding surface sections of the mine field, in order to avoid the separate searching of the individual mines. Presentation of the invention
  • the invention is therefore based on the object to design a method for clearing a minefield of the type described so that a sufficient area-wide pressure load can be applied to minefield sections to ignite the mines located in this minefield section in a simple manner.
  • the invention solves this problem in that the mines of the minefield are ignited with the aid of trigger weights which are thrown onto the minefield in a predetermined grid.
  • the mines laid in the impact area of the trigger weights can be ignited via their own trigger, which then leads to a complete evacuation of the portion thrown with the trigger weights if care is taken to ensure that the trigger weights hit in a predetermined grid.
  • the grid size must be limited to a level that ensures a sufficient, area-wide pressure load on the ground for the response of the pressure-sensitive ignition triggers of the mines.
  • the impact density of the trigger weights according to the predetermined grid can be easily ensured by means of appropriately directed trajectories of the trigger weights, especially since the flight distance can be kept comparatively small, so that a locally narrowly limited impact area results at a predetermined departure speed and direction, especially in the case of a spherical shape the trigger weights, which makes the trajectory of the trigger weights independent of their spatial position.
  • Another possibility of securing a predetermined impact grid is to provide the individual trigger weights in the grid points of a network, so that the trigger weights are not only kept at a predetermined mutual distance with the help of the network, but also while maintaining these ses distance can be thrown on the mine field section to be cleared.
  • the sectioned clearing of the minefield can be facilitated with a substantially rectangular basic shape of the network, because rectangular sections can be strung together over the minefield with only a slight overlap.
  • a net with an essentially rectangular basic shape can be spread well over the entire net area via corner weights that have a greater mass than that of the individual trigger weights in the region of the lattice points.
  • the rectangular, leporello-like net folded in the basic form can be wound onto a drivable centrifugal drum, which is supported in a housing that outwardly diverging, tangential throwing guides for the Has corner weights of the network, wherein the throwing guides and / or the corner weights of the outer turn of the wobbled Network can be released depending on the number of revolutions of the centrifugal drum.
  • the leporello-like net fold allows the net to be easily spread out over the corner weights when they are moved apart.
  • the throwing guides for the corner weights running tangentially to the centrifugal drum diverge outwards, so that the corner weights of the net rotated by the centrifugal drum are spread apart over the throwing guides while the net is spreading when the net or the throwing guides are released for departure ,
  • the throwing distance for the net can be adjusted depending on the selected number of revolutions of the centrifugal drum by swiveling the throwing guides around the axis of rotation of the lying centrifugal drum.
  • the centrifugal drum can have detachable centripetal anchors for the corner weights of the outer winding of the network, so that these corner weights are held against the centrifugal force against the centrifugal force and only released until the centrifugal drum has reached the intended number of revolutions .
  • the throwing guides for the corner weights of the network have an open closure, which forms a sliding guide for the corner weights rotating in the housing of the outer turn of the net wound on the centrifugal drum. This sliding guide of the closure deflects the corner weights running around the housing shell in accordance with the circular path determined by the housing until the closure is opened, which results in the net being thrown out with a corresponding expansion.
  • a clearing vehicle is provided on which a throwing device connected via a distributor to a reservoir for the trigger weights is provided with a plurality of acceleration devices lined up next to each other for one trigger weight connect the discharge guides, which diverge in the discharge direction, for the trigger weights.
  • the grid spacing of the thrown release weights in the direction of travel can be determined via the travel path of the clearing vehicle that only the distribution of hits across the direction of travel is to be specified via the discharge guides, in that the discharge guides diverge accordingly in the discharge direction.
  • the triggering weights are individually accelerated to a predetermined take-off speed via the acceleration devices arranged side by side, which, due to the matching masses of the triggering weights and the alignment of the launching guides, leads to predetermined trajectories of the triggering weights with a desired impact density. It is only necessary to ensure that the accelerating devices to be juxtaposed are regularly fed the triggering weights, which can be ensured in a simple manner via a distributor connected to a reservoir for the triggering weights.
  • the acceleration devices themselves can be constructed differently, because the only thing that matters is to accelerate the triggering weights to a predetermined release speed. This could be achieved, for example, by means of a stamp.
  • the throwing device consists of a centrifugal drum rotatably mounted in a housing about a horizontal axis, which has axially arranged, radially protruding drivers for the release weights offset with respect to the drum axis, and that the drivers are resiliently supported against the direction of rotation.
  • the release weights gripped by the radially protruding drivers can be sufficiently accelerated via the rotating centrifugal drum, the resilient support of the drivers reducing the otherwise shock-like load caused by the release weights striking the drivers and gradually accelerating the release weights via the support spring ,
  • the angular displacement of the drivers with respect to the drum axis also brings about a torque load of the centrifugal drum distributed over the circumference due to the successively supplied trigger weights.

Abstract

La présente invention concerne un procédé et un dispositif permettant de débarrasser un champ de mines comportant des mines pourvues d'un système d'amorce sensible à la pression. Afin de débarrasser ces mines, ces dernières sont soumises à une charge de pression qui déclenche une amorce. Afin que les conditions de mise en oeuvre du procédé soient favorables, les mines dudit champ de mines sont amorcées à l'aide de masses de déclenchement (3) qui sont projetées dans un quadrillage prédéfini, par exemple sous forme de réseau, sur le champ de mines. Cette invention concerne des dispositifs de projection centrifuge destinés à un réseau pourvu desdites masses de déclenchement, ainsi que pour des masses de déclenchement séparées.
