Definitions

  • the invention relates to a device for the controlled triggering of avalanches, in which a lifting plate is pivotally mounted on a base plate resting on the base plate, which is pivotable by means of a lifting device swung up and abruptly downwards, wherein on the lifting plate lateral cantilevers are attached.
  • the lateral cantilever plates are substantially fixedly connected to the lifting plate and serve to provide a wider area for catching snow, which then jerkily releases the snow on a wider line in order to trigger an avalanche accordingly.
  • the triggering due to the low snow depth is not reliable, since the dropped in one place amount of snow is not sufficient to achieve the appropriate triggering of the avalanche.
  • the invention is based on the object to improve a device of the type mentioned so that even at lower snow depths the critical amount for the triggering of snow is achieved.
  • this object is achieved in that the lateral cantilevers are pivotally mounted on the lifting plate, wherein means are provided for lifting the cantilever plates in relation to the lifting plate between the lifting plate and cantilevers.
  • the means for pivoting the cantilever plates by hydraulic lifting cylinder formed, whereby a simple application without a large number of mechanical parts is achieved.
  • screw spindles or worm gears could be used instead of hydraulic lifting cylinders.
  • the lateral cantilevers can each be executed in two parts, wherein the two parts are connected to one another parallel to the pivot axis on the lifting plate extending further pivot axis. This ensures that the active surface of the lateral cantilevers can be reduced laterally when z. B. due to high amounts of snow for lifting the lifting plate and the associated cantilevers too much effort would be needed.
  • the two parts of each cantilever plate can be stretched by a spring in its extended position, which ensures that the extended position, so that the surfaces of both parts of the cantilever plates lie in one plane, is present as a basic position.
  • the two parts of the cantilevers can be locked in the extended position by means of bars, which ensures that when the Cantilever plates are swung up to deposit the amount of snow thereon on the central lifting plate, the entire cantilever plates are swung up and the entire amount of snow is just deposited on the lifting plate.
  • This further flap can be pivoted downwardly during pivoting down of the lifting plate from the swung-up position in a plane with the lifting plate, whereby the two movements, namely sudden downward pivoting of the lifting plate and folding the other flap for the purpose of unloading the amount of snow can be adjusted accordingly.
  • the device for pivoting the further plate may be coupled to the lifting and triggering device of the lifting plate, which then, when the downward pivoting of the lifting plate is triggered, at the same time the further flap is folded on the downhill edge of the lifting plate.
  • the lifting plate may be divided parallel to the pivot axis, where appropriate, omitting the lateral cantilevers, the two parts hinged together and kind of a toggle lever by pulling up the joint connecting the two parts be raised.
  • This allows the snow located on the mountain-side raised part to be shifted slightly uphill, whereby the part of the lifting plate facing away from the valley, that is, the part facing away from the pivot axis deposits the snow first at the valley-side edge, wherein the jerky depression the lifting plate to the mountain-side pivot axis stretching the toggle lever takes place, which causes the one hand, the discarding the mountain side pent-up mass of snow and on the other hand, the downhill pushing the snow located in front of the valley end, the two masses united by the sudden downward movement make the avalanche release.
  • the free end of the pivot axis of the lifting plate facing away from the part may be performed at approximately in the fall line of the slope rails, whereby a precise pulling up of the two parts and a guided downward folding of the lifting plate is possible.
  • the pivot axis of the lifting plate can be performed on the rails for the valley-side folding down the lifting plate. It is thus initially moved when triggering the downward movement of the lifting plate, the entire toggle-like raised lifting plate downwards, so there is a higher impulse on the downhill snow mass.
  • a particularly simple control of this Movement can be provided for moving the lifting plate along the rails a cable or a screw.
  • a further plate-like part can be hinged at the free end of the pivot axis of the lifting plate, wherein the free end of the pivot axis of the lifting plate facing away from the part by means of push rods of a push plate or the like is guided and wherein the further plate-like part is guided with its free edge directly to the rails.
  • control, drive and / or storage devices for print media or energy can be arranged in a separate from the lifting housing or housing part. This also ensures that snow accumulations in the lee of the device due to wind loadings are avoided. Such snow accumulations can hinder the sudden downward movement of the lifting plate in a device with lateral cantilevers under adverse circumstances.
  • a fixable by means of a cable pendulum support can be provided for fixing the lifting plate in the raised position, wherein the cable is provided with a freewheel device having winch. It therefore needs to trigger the downward movement of the lifting plate, only the brake of the cable to be solved, so this releases the pendulum support and thus lifting plate due to the freewheel device.
