Description

The invention relates to rescue equipment.

Rescue devices are known for rescuing people in distress, for example devices for delivering throwing tips for rescue in a fire, containing balloons, adjusting coils with a stopper and cables. Rescue devices are also known, consisting of a rope on which bags are fastened, reinforced with transverse straps.

The disadvantages of the known devices are the complexity of the design and the high cost of time to bring the devices into working condition.

Closest to the proposed technical essence is a device for saving people in distress, containing a cable, on which devices are made, made in the form of segments of a rope of smaller diameter than the cable itself, the lower ends of the segments are fixed on the rope, and the upper ends are movable, by couplings (SU 556817 A1, 06/25/1977).

The disadvantages of this device are that when it is used, pieces of rope can cause damage to people, rigid movable couplings do not wrap well on the board, there is no signal light and sound alarm at the lower end of the rope, which makes it difficult to use the device in smoke or in the dark.

The problem to which this invention is directed is to create a rescue device devoid of the disadvantages indicated above, and which can be used both on water and on land.

The technical result achieved by the implementation of the invention is to accelerate the delivery of rescue equipment to those in distress from an aircraft, to increase the efficiency of its use.

The specified technical result is achieved in that in a device for saving people in distress, including a rescue rope with a device for securing the rescued, made in the form of segments of a rope of smaller diameter, the lower ends of which are fixed through the couplings on the rescue rope, and the upper ends are fixed through the couplings fixed on the rescue rope movably, according to the invention, the lower ends are fixed through short couplings, and the upper ends through long, segments of a rope of a smaller diameter have protective ru lugs made of reinforced heat-resistant fibers with a braid of basalt twisted fibers, while the short sleeves are made of metal and the long sleeves are made of elastic material, for example rubber, while a sealed container with a device for feeding intermittent sound is fixed to the lower end of the rescue rope and light signals, and on the top there is a loop for hanging on the carabiner of the rope of a helicopter winch.

The sealed container contains a power source, a device for generating intermittent sound and light signals, sound and light emitters, a switch for supplying electricity to the sound and light emitters.

The case of the airtight container has hooks for tapes, tightening the rescue rope into an annular bay and securing the bay on an airtight container.

The invention is illustrated by drawings, where figure 1 shows a rescue rope, lowered from a helicopter; figure 2 - section of the rescue rope with loose loops; figure 3 - section of the rope, the loops of which are stretched along the rope to wind the rope into the bay; figure 4 is the same, on an enlarged scale; figure 5 is a view of a deflated rescue rope, the loops of which are already previously disbanded; figure 6 is a transverse section of a helicopter (MIG-8) with a winch and rescue device, rolled into a bay and hung on a carabiner of the winch rope; Fig. 7 - a rescue rope rolled into a bay and secured with tape on the hooks of an airtight container (the auxiliary cylinder is shown conditionally, because after the formation of the bay, the cylinder is removed, and the bay is fastened by running it with the airtight container); on Fig - scheme of rescue operations: A - rescue rope lowered to the flat roof of a burning building; B - a helicopter lifts a string of people fixed on a rope; B - a helicopter lowers people to a free area; G - helicopter slowly advances the rope with loose loops along the front of the burning building.

The device for saving people in distress has a rescue rope 2 attached to the winch of a helicopter 1 with a device for securing the rescued, made in the form of segments 3 of a rope of smaller diameter, the lower ends of which are fixed through short couplings 4 on the rescue rope, and the upper ends are fixed through long couplings 5 mounted on the rescue rope movably. The rope segments 3 of smaller diameter have protective shirts 6 made, for example, of reinforced heat-resistant fibers with a braid of basalt twisted fibers, while short couplings are made, for example, of metal, and long couplings are made of elastic material, for example, rubber. At the lower end of the rescue rope, a sealed container 8 with a device for supplying intermittent sound and light signals is fixed, and at the upper end there is a loop 9 for hanging on the carabiner 10 of the rope 11 of the helicopter winch 12. The sealed container contains an electrical power source 13, a device 14 for generating intermittent light and sound signals, sound 15 and light 16 emitters, a switch 17 for supplying electricity to the sound and light emitters. The device has an auxiliary cylinder 18, which provides the convenience of folding the rescued rope with extended loops and elastic-elastic couplings 5 into the annular bay 19. The body of the airtight container 8 has hooks 20 located on the corners of the rear and front planes of the container, for tapes that tighten the rescue rope into the annular bay and securing the bay on the body of a sealed container. The upper ends of the segments of the ropes 3 are fixed in a metal washer 7, which is pressed into the rubber to strengthen the lower end of the long elastic sleeve 5. 21-folding hook for lifting the load.

The device operates as follows.

When the alarm is announced, the bay 19, always stored in a certain place, is taken and hung on the carabiner 10 of the winch 12 of a free helicopter, ready for flight. The bay should always be prepared for hitching, for which, after each use of the device, the rope is wound on an auxiliary cylinder 18 with previously stretched loops 3. After that, the cylinder 18, worn on the container body, is pulled out of the bay 19, and the bay, to maintain its shape and for attachment to the container for hooks 20, tied in several places with tape. When approaching the object, the switch 17 provides power, the tape rings are cut or loose quickly untied nodes of the tape and the device is dropped from the helicopter, while a dangerous jerk of the rope from a light container should not be. If necessary, if an additional load has to be fixed at the end of the rope, the rope breakthrough can be mitigated by winch 12.

The helicopter hangs over the object, lowers the rescue rope, for example, onto the flat roof of a high-rise building, raises people who are fastened on the rope, lowers them to the nearest free area.

When possible, the helicopter pilot can slowly lead the rope closer to the wall of the skyscraper and save people who were able to grab the rope in a hopeless situation.

The proposed device can be used when people need to be removed from the ice, from the mountain range, from the glade of the burning forest, pulled out of the swamp, from the abyss or gorge. Light and sound signals make it possible for people in distress to pay attention to the descent rope at night or during smoke, while the light signals help the helicopter crew to see the location of the end of the rope. The rope and container rolled into the bay are easily transported and hung on the carabiner of the helicopter’s winch, ready for flight, which significantly speeds up the assistance.

Protective shirts, thickening thin ropes, practically do not injure people who are fixed on the rescue rope, if they are accidentally briefly touched by fire, the shirts remain intact.
