RU62889U1 - DEVICE FOR AUTOMATIC INFLATION OF A DESANTABLE LIFE RAFT - Google Patents

Abstract

The utility model relates to the field of rescue equipment designed to rescue people floating on the surface of the water after leaving an emergency vessel and is aimed at improving the technical and economic data of inflatable liferafts, landing from an airplane, by providing automatic inflation of the liferaft after it is brought down in the accident area without participation of the saved. The goal is achieved by incorporating into the existing devices of the raft gas-filling system a temporary device providing automatic, without the participation of the rescued, inclusion of the raft gas-filling system after it is splashed and the parachute is separated from the raft. When splashing, the parachute is separated from the raft and pulls out the hairpin of the temporary device and turns it on. After a specified time, the raft is freed from packaging, the gas filling system is automatically turned on, inflated and it is ready for use by the rescued.

Description

The utility model relates to the field of rescue equipment, in particular to inflatable liferafts intended for airborne landing in the accident area when rescuing people floating on the surface of the water.

Analysis of information sources showed that inflatable liferafts can land on their own and in aircraft containers. Known containers for aviation rescue KAS-90, KAS-150. KAS-500, designed for landing air rafts and rescue equipment from aircraft. They consist of a container body with the placement of life rafts and rescue equipment, a parachute system with an exhaust device placed in a parachute chamber.

Containers are dumped from the aircraft into the accident area. When the parachute is opened, rescue cargoes are removed from the container, forming a chain of rescue equipment, which is splashed and floats on the surface of the water. Containers KAS-150 and KAS-500 as part of rescue equipment have inflatable liferafts.

After finding the life raft, the rescued swim up to it, find a rope ring on its end, take it out of the pocket, rest its knees on the end of the raft packaging, pull it with both hands to failure, including the raft packaging opening system and the gas filling system. After inflating, the rescued enter the raft along the ramp.

As a prototype, a device for inflating an airborne raft used in a container KAS-150 (technical description and operating instructions P 159-0000 TO, organization P / Y V-2512. 1974) was adopted.

The disadvantages of the considered systems, including the KAS-150 liferaft, are:

- inflation of the liferaft is carried out by the actions of the rescued,

swam up to the raft by pulling out the ring of the tracing rope. This work can only be done by a specially trained person who has not lost physical activity. There are few such people among the rescued, especially the passengers of the ships;

- when folded, the liferaft has small dimensions. Flashing lights may only be used after inflating the raft. As a result, the detection of the raft, rescued by floating on the surface of the water, especially when the sea is rough, is difficult;

These shortcomings significantly reduce the likelihood of using liferafts to save people floating on the water surface.

The objective of the utility model is to increase the efficiency of rescuing people who have left an emergency vessel and are floating on the surface of the water.

The problem is solved in that a temporary device is included in the known device for inflating an airborne liferaft, consisting of a parachute cord, a raft for opening the raft of a raft, a launching device for the gas filling system, which automatically, without the rescue, inflating the raft with gas from the gas filling system after it is brought in with a given delay interval.

New significant features of the proposed utility model are:

- inclusion of a temporary device in the device;

- connection of the executive cable of the temporary device with the ring of the gas filling system;

- the connection of the studs of the temporary device to the top of the parachute uncoupling halyard;

- connection of the executive cable of the temporary device with the ring of inclusion of the gas filling system.

Introduction to the proposed utility model of essential features ensured the solution of the problem of automatic inflation

landing a liferaft without the participation of the rescued and increasing the likelihood of its detection by people floating on the surface of the water.

Figure 1 shows a diagram of a utility model of a device for automatically inflating a landing assault raft. The device for automatically inflating the landing raft, consists of a parachute 1, a parachute uncoupling 2, a halyard 3, an executive cable 4, a temporary device 5, a temporary device 6 switching device, a temporary device turning on pin 7, a temporary device cable 8, a raft packaging opening system 9, a system gas filling 10.

The device is used as follows:

When the raft is brought down, the parachute 1 is disconnected from the upper part of the uncoupling 2 and, under the influence of wind, is removed from the raft, the halyard 3 is fastened, fixed to the upper part of the parachute hitch and the executive cable 4 of the temporary device 5, the device for switching on the temporary device 6 is activated, at the end of the specified time the cable 8, attached to the pin of the temporary device 7, includes a raft packaging opening system 9, the raft is freed from packaging, the raft 10 gas filling system is turned on, the raft is inflated, the rescued are taken up by tr ny in the raft.

The implementation of the utility model does not require a significant amount of research, design studies and material costs.

Use of the utility model is possible during the modernization and creation of new life rafts.
