Description

The invention relates to the field of preventive measures relating to artificial avalanche descent, and in particular to mobile motorized pneumatic devices for reducing avalanche danger by throwing explosive charges on mountainous snow sections to initiate a planned avalanche descent during their explosion without catastrophic consequences.

A known method of protection against snow avalanches by means of preventive bombardment of avalanche slopes in places where snow is accumulated from artillery guns or detonated by an explosive charge in the upper part of the slope [1], p. 74. Artillery systems, as well as howitzers and anti-aircraft guns are used to implement artificial dumping of snow avalanches .

The disadvantages of this method of dealing with avalanches should be considered:

- the need to build roads to transport heavy and expensive equipment to dangerous places,

- the impossibility of determining the actual danger of avalanches, because their descent depends on many factors (weather conditions, humidity, snow conditions, etc.).

The closest in technical essence to the invention is a pneumatic gun firing compressed air avalanche bombs with explosives for the artificial discharge of snow avalanches [2]. The device comprises a barrel, a source of compressed gas, a channel connecting the source of compressed air to the barrel, replaceable rupture disks, a chamber for compressed air (receiver), a pipeline, and compressed air cylinders.

A burst disk overlaps the channel connecting the receiver to the barrel. When compressed air is supplied from the cylinders to the receiver and the set pressure is reached in it, the rupture disk is destroyed and opens the channel connecting the barrel to the source of compressed gas, which ensures the supply of compressed gas to the barrel and the projectile is pushed out of it.

The disadvantages of this device are the need for each shot to disconnect the barrel from the receiver by means of a bolt connection for laying a new projectile and replacing the rupture disk, low firing accuracy due to the regulation of its range by the rupture of the disk, the lack of mobility of the device and the need for a supply of compressed air cylinders.

The aim of the invention is to simplify the design of a mobile pneumatic device to reduce avalanche hazard, increase its performance and reduce labor costs when performing the process.

This goal is achieved in that the mobile pneumatic device for reducing avalanche danger contains a barrel, a source of compressed gas, a channel connecting a source of compressed air to the barrel, a chamber for compressed air (receiver), a pipeline and cylinders with compressed air, while between the barrel and receiver a crane is installed, the handle of which is connected to the pneumatic cylinder and it contains a screw regulator with a pointer, a spring and a ball, and in the cover of the valve body there is a spherical recess, while connecting to the handle spool crane loading the barrel is made with its muzzle, and a compressed air compressor is used for pumping cylinders.

The drawings show a mobile pneumatic device for reducing avalanche danger, side view 1, view 2 - device, side view, top and section, view 3 - crane control.

The device comprises a vehicle 1 with a compartment 2 for crew life support, a high-pressure compressor 3 and cylinders for compressed air 4, in the back of the vehicle 1 is mounted a swivel bearing 5 with a fixed hinge 6, on which a barrel 7 with receivers 8, pneumatically connected to a crane, is mounted 9 and cylinders 4. Also on the device are the sights 11 and control knobs 12. The handle 13 of the crane 9 is kinematically connected to a pneumatic cylinder 10 connected by an air channel to the receiver, in it a screw regulator 14 with a pointer 15, a spring 16 and a ball 17 is laughing, and there is a spherical recess in the cover 18 of the valve body 9, while the valve spool 19 is connected to the handle 13, the barrel 7 is charged from its muzzle, and compressed to pump cylinders 4 compressor 3 is used with air, while the screw regulator has marks with values of the range of the shot

A mobile pneumatic device for reducing avalanche danger works as follows.

Vehicle 1 with compartment 2 for crew life support arrives at a place where avalanche hazard reduction is required. The high-pressure compressor 3 pumps compressed air into the cylinders 4, a charge is inserted into the barrel 7, by turning on the support 5 the barrel is directed towards the avalanche hazard section on the mountain slope, is guided by the arms 12 vertically along the sight 11 and fixed by the rotary handle of the hinge 6. Screw regulator 14 the pointer 15 sets the pressure required for the firing range, by opening a valve (not shown), compressed air from the cylinders 4 enters the receivers 8 and the pneumatic cylinder 10. When the set pressure is reached, the ball 17 compresses the springs at 16, it leaves the spherical recess in the cover 18 of the valve body 9, releasing the handle 13, which, under the force of the cylinder rod 10, turns the spool 19 to the “open” position, and compressed air from the receivers 8 enters the barrel 7, pushing the projectile into the avalanche hazard section where it explodes causing collapse of snow masses. To reuse the device with the handle 13, the spool 19 is placed in the “Closed” position until the ball 17 contacts the spherical recess in the lid 18, a new charge is inserted into the barrel 7, and the device is ready for reuse.

Using the proposed device will eliminate the replacement of the rupture disk, assembly and disassembling operations during reloading, increase the accuracy of hits due to more accurate dosing of air pressure by the regulator.
