Device for self-escaping of people in snow avalanche
FIELD: rescue equipment.
SUBSTANCE: invention relates to the means which enable people to escape or draw attention to themselves when in contact with the snow avalanche. The device for self-escaping of people in the snow avalanche comprises an avalanche cord, a signal cartridge and a parachute. At that the signal cartridge, the parachute and the avalanche cord are connected in series with each other.
EFFECT: invention is directed at the salvation of a person when in contact with an avalanche by preventing its covering with the avalanche material - snow, ice, and removal of a person out of the avalanche flow to the surface of the snowdrift.
The invention relates to enabling people to escape or to attract attention when in contact with the snow avalanche.
Known avalanche cords (length 30-40 m), United with the human body, which when released the latest in an avalanche bloom and may remain on the surface of the avalanche of debris that would be found quickly bombarded with an avalanche of man. However, such an outcome is not always the case, as the avalanche cord may be buried by an avalanche, which makes the low efficiency of this device (Kotlyakov C. M. the World of snow and ice. M.: Nauka, 1994).
Known taken as a prototype device - avalanche cord, used in the French Alps, representing bright, color, nylon rope length of more than 15 meters, fixed on the body by its end and provided at the other end of the small color balloon, filled with helium (K. F. wojtowski. Rules of conduct on avalanche slopes. Google http://tkb.h12.ru>artikles/lavina 1.shtml).
Such a device increases the probability of detection and the salvation of man, buried in an avalanche, but does not guarantee, as the probability of death from suffocation during his sniffing out remains large.
The aim of the proposed invention is the implementation of the rescue of a person when in contact with an avalanche by predator the statutory sleep his material avalanches - snow, ice, stones, etc. this goal is achieved by a device for rescue of people in an avalanche, including avalanche cord, the device contains a rocket and parachute, rocket, parachute and avalanche cord are connected in series with each other.
The proposed invention is illustrated by drawings, where Fig.1 shows a General view of the device of Fig.2 shows the device is removed from the front wall of Fig.3 presents a diagram of the starting device, and Fig.4 is a diagram of the operation of the device.
The device consists of a flat container 1, in which the chute 2 and avalanche cord 3. On the side of the container 1 is fixed to the rocket with 4 starter rope 5 and the ring 6. The container is fixed on the man's back straps 7. Rocket 4 are connected by a metal chain 9 with the chute 2, the latter is connected avalanche cord 3 to the container 1 (Fig.1).
The device operates as follows.
At the first signs of the approaching storm (visual or auditory) of the person pulling the ring 6 of the starting rope 5 4 missiles. The rocket goes up, pulling behind him a chute 2 and avalanche cord 3 (Fig.2 and Fig.3).
At the height of 40-50 meters parachute 2 is opened and creates a force F, hampering the movement of the person in avalanche flow whose velocity is equal to V (Fig.4). Power F has two components: the force F, zamedlja the General movement of a person in avalanche flow, and force F, forcing the body to rise to the surface of the avalanche flow (Fig.4). When the ascent of the human body on the surface of the avalanche flow disappears strangulation hazard, and significantly reduces the risk of damage to the body chunks of ice and rocks, which due to its gravity is localized in the lower part of the avalanche flow. At this time the container 1 protects back of a man from shock. Decreasing the speed of the person in avalanche flow due to the inhibitory action of the parachute 2 avalanche overtakes man, and active avalanche stops him. If a person gets injured or loses consciousness, for example, from the action of the shock wave accompanying an avalanche, avalanche cord, which necessarily remains on the surface of avalanche debris, allows you to quickly locate the victim and help him.
Flying up the rocket 4 shines a red light, giving thereby a distress signal. Connection of 4 missiles with a parachute 2 metal chain 9 eliminates the possibility of breakage of the connection due to thermal action of the hot gases of the rocket charge.
