Definitions

  • the invention relates to a method and a device for triggering avalanches.
  • DE 698 12 150 T2 describes a method and an apparatus for triggering avalanches by igniting an explosive fluid and is thus the Canadian patent 2 202 236 comparable.
  • Swiss patent 369 158 avalanche slopes are bombarded with war weapons: mine throwers, hand grenades, grenades with impact fuze and stabilizer wings and the like. come used.
  • a stationary device for collapsing a snow plate describes DE 698 01 580 T2 , The device is designed as a blast hammer and lifts off to let exploded gas escape.
  • DE 600 14 993 T2 solves the problem by a device containing an explosive mass and a system for their ignition, the device can be transported by a helicopter.
  • DAS 1 287 597 proposes the application of plastic mats on slopes susceptible to avalanches, which are subjected to compressed air for detachment of snowboards, if necessary. With explosives also the technical solutions of the US 4,817,529 . EP0108013 . JP2002506512T ,
  • the aim of the invention is to substantially reduce the risk of triggering deliberate avalanche discharges, to propose a safe and at the same time cost-effective method of inducing deliberate avalanche discharges.
  • the present invention seeks to solve the stated object of deliberately triggering avalanche discharges by creating suitable local air pressure differences or vibrations in or on the avalanche suspected snow mass without the described disadvantages with the combination of known method steps and own inventive step. It should be achieved by stationary or transportable devices that intentional avalanche can be technically easily realized. For this purpose, the previously widespread use of explosives, weapons of war or similar missiles should be avoided.
  • the invention is based on the finding that the disadvantages and hazards of the known methods and associated technical devices for intentional Generation of avalanches according to the invention by the use of pneumatically generated energy pulses can be avoided by the potential energy of highly compressed, preferably inert gases abruptly, optionally also directed, released and thereby produce by means of a device described low-frequency oscillations for deliberately triggering avalanches by any arbitrary often short-term and locally generated air pressure change with positive or negative amplitude, starting from a pulse source, propagating in or on the snow mass and possibly in the geological structure of the avalanche-prone environment.
  • a pulse source (pulse generator) of an energy storage E which is permanently installed or in a means of transport such as in a helicopter, via a control unit S and a connecting hose V continuously supplied with highly compressed gas in adjustable amount and adjustable pressure and thereby in the situation is offset to produce a selectable number of local air pressure differences to normal pressure
  • this device can either be installed stationary, or e.g. is brought to the place of use by means of an aircraft and positioned there as required, and the pulse generator is attached both to a tubular tether or to one or more hoses and to a tether,
  • a procedurally required required gas inlet pressure level is first passed through the connecting hose before the later working gas pressure in the pulse source, as well as in addition to the working (gas) pressure of the technical device by a second hose in the tether described can be permanently supplied and thus the energy content the pulses and the pulse frequency can be controlled remotely and
  • compressed gas source mainly commercial compressed gas containers ("gas cylinders"), individually or connected as a battery connected, are used, whereby the available amount of potent energy can be increased arbitrarily.
  • the technical device for generating high energy pulses is based in a conventional manner on the sudden release of energy highly compressed, mainly non-combustible gases and thereby generated low-frequency oscillations or local air pressure differences, such as in DE 19843292 C2 / E 03B 3/15 and SU / CCCP 732509 / E 21 B 43/26.
  • the device described is limited, inter alia, that the supply of the pre-pressure chamber 2 from the permanently connected supply hose takes place such that at temporary filling the supply line V in the pre-pressure chamber 2 by axial displacement of a functional element K with respect to the at Supply hose connected supply channel can be closed or it is in the case of permanent supply of pre-pressure selectable size by means of a parallel hose via its own control device and separate connection to the pulse generator to the power source E is connected.
  • the device described is further distinguished from the prior art by the nature and shape of the material of the sealing elements by the partitions 3, 5 and 7 are made of lightweight and high-strength materials and have suitable form elements for receiving the preferably elastic sealing material.
  • Another essential difference consists in the arrangement of a flow restrictor 6 in the connecting line between the partition wall 5 and 7, with the dimensioning of the pulse frequency can be influenced.
  • the solution according to the invention is further characterized in that the technical device both in and over the snow mass, of the avalanche danger emanates, can be positioned, and that the technical device known features for the directed emission of pressure waves, such as US Pat. 3923122 / G 01V 1/04, may have.
  • the pressure hose can be wound on a roll or the like to facilitate transportation.
  • the rewinder is then stably mounted under the helicopter, for example.
  • a pulse generator can serve a cylindrical body, for example, has a diameter of 60 mm and a length of 600 mm.
  • the cylindrical body consists essentially of corrosion-resistant steel or a titanium alloy, other functional elements are elastomers such as rubber, PTFE or PUR.
  • the wall thickness of the cylinder is about 5 mm, the cavity between 0.5 and 5 liters.
  • pre-pressure 10 to 50 bar are set, as working pressure 50 to 100 bar.
  • the gas hose is designed for a pressure of 300 bar.
  • the pulse rate can be 1 to 5 pulses / sec. It is adjustable and takes into account the method of provoking the avalanche emissions, that is, whether the energy pulse in the snow of the avalanche or above is triggered.
  • the pulse generator may also be spherical.
  • the content of the method for triggering avalanche discharges according to the invention presented is that the internal energy of highly compressed gases is abruptly released as an energy pulse from an adjustable in height threshold pressure and this pulse is passed both to the surrounding air and / or earth layers and snow masses and leads to a local pressure change, and that this generates a low-frequency oscillation with at least one positive and negative amplitude for a short time substantially deviating air pressure and thus acts on avalanche-hazardous snow masses, that a departure of the same is caused and that in the pulse generator used to generate the energy pulse either for the temporary supply of the admission pressure gas at fixed pressure and for the ongoing supply of pressure variable working gas between the control device S to the power source E and the pulse generator no change of the pressure hose V is required and / or that with two permanently connected hoses between the power source with a switchable or two separately operating control (s) S at the power source E, the ratio between form and working pressure in the pulse generator changeable and thus pulse frequency and energy content of the pulses are selectable and that the connecting
  • the compressed gas is not flammable or it is a mixture of non-combustible gases, which is emitted at its sudden release of a device according to claim 5 or a similar arrangement directed to a snow mass.
  • the energy pulse is released after immersing the device according to claim 5 in the snow mass in this
  • the control device S for commissioning and decommissioning and for the choice of function-triggering pressure threshold is located on the compressed gas tank, the means for supplying the process-related form in the pulse generator is also located on this and both the form and the working pressure without change are supplied by the same pressure hose ,
  • the pressurized gas container consists of several battery-connected individual in the sense of gas exchange interconnected individual containers
  • the device consisting of the technical device and the compressed gas container is designed such that it is air transportable and can be brought by an air transport vehicle to the place of use and placed there in or near the avalanche suspected snow mass. It is thereby proceeded that about used pressure hose for the transport of the pulse generator is sustainably armored and has a sufficient length that a flying air transporter, even without being affected by the process of triggering the avalanche, carrier of the energy storage and location of the triggering Impulse is.
  • a second pressure hose is located within or next to the supporting pressure hose armature for the connection between the compressed gas tank and the technical device, with which the process-related form in the pulse generator can be additionally provided adjustable via a switchable or a second control device to the power source and thereby both the frequency and the energy content of the pulses are variable.
  • the air transport is a common variant for carrying out the method, it is helicopter or zeppelin or balloon or cable car or the like as air transport used.
  • the pressure hose V which may have a length of over 100 m, be wound up for transport.
  • the device can be installed in the same place one or more times.
