Abstract

FIELD: life-saving methods and devices.

SUBSTANCE: invention relates to rescue equipment on water. Individual rescue safety device is made of strong water-repellent transparent film and is capsule of vital space, which is limited by double wall, divided into non-communicating perimeter circular compartments, filled with compressed air from compressed air cylinder. Seat in the capsule has a hygienic "valve" allowing to use a hygienic package with a natural need. On external bottom part of device there are ballast pockets, which are necessary to maintain stable vertical position of capsule in case of commotion and simultaneously are water anchor, reducing rate of capsule movement in windy weather.

Description

Individually, the lifeguard protective device ISZS MEDUZA is made of a durable water-repellent film and is a capsule, and the living space in it is limited by a double wall divided into non-communicating circular perimeter compartments filled with compressed air from a can of compressed air.

The proposed device is intended for use in extreme conditions (during death) to rescue crew members. The device relates to the field of rescue equipment. Due to the very quick bringing the device into working condition, it can be argued that it corresponds to the high level of technology, since it is guaranteed that the task of rescue in any weather conditions. The life support of the victim depends on the completeness of the device: 1. NZ products and water. 2. An autonomous heat source of the “Teploid” type. The disadvantage of the existing rescue equipment is unwarranted protection from the cold environment, the Meduza satellite-borne safety system eliminates this disadvantage. The second advantage is the speed of bringing the device into working condition. The third advantage is the long duration of protection of the crew member from hypothermia. When using ISUS “Meduza” in warm waters, it is used at the same time as a lifebuoy in the presence of an external cord strapping of the capsule. When using the Meduza satellite navigation system in avalanche-hazardous conditions, a simplified version is possible, because ISUS “Meduza” will always be located on the surface of the avalanche due to its lightness and large volume. In all the drawings (figure), the device is shown from the side, but the strapping of the device can be conveniently dispersed inside the capsule based on ease of use. The accompanying drawings depict the equipment of the Meduza satellite control system with the necessary means of human life support. The main requirements for the reliability of life support:

1. A stock of products and water.

2. Staffing with autonomous heat sources - “Teploidom”.

3. The Medusa ISZS kits should be located on the upper deck of the vessel with easy access to them.

The rigidity of the walls and the preservation of the shape of the capsule is ensured by the fact that the inter-wall space of the capsule is divided into circular perimeter compartments not communicating with each other, filled with compressed air from the spray can. (5) The air supply in it should provide two-time filling of the capsule walls, the walls are filled with air instantly when the valve is opened from the (tap) - 8Е to bring the device into working condition. Access to the capsule is through the capsule inlet, located on top, is closed with a double lock (such as a zipper) - (10) The human air is supplied through the air duct through the mouthpiece (2), (1) is reserve, the manual pump can also support the life support of the capsule (fur type) - (4).

The shape of the capsule fills the body of the jellyfish, but the wide (upper) part is shifted to the back of the device (to maintain a more vertical position of the capsule in the water) when the person is fastened to the seat (13) with safety belts (16)

Thanks to the check valves (9), the compartments of the capsule wall ensure reliable preservation of the capsule shape.

Support for the vertical position of the capsule in water (during unrest) is provided by ballast pockets located outside on the bottom of the device, made of a material that provides self-deployment. Their upper part should be open, and in the lower part there should be openings (22) (drain) with a diameter of at least 60 mm.

Condensate and water entering the air duct are collected in the water collector - (6) and pumped overboard with a hand pump - (3). The capsule should be equipped with cargo loops - lifting, anchor and ligament located on the outside of the device (23, 24).

The seat (13) in the device has a hygiene valve (11) with a hygiene bag (12)

Check valves (suction) - (14) allow air to enter the capsule. Exhaust - excess outlet with an air duct to it from the bottom of the capsule.

The invention is shown in the drawings, Figures 1, 2, 3, 4, 5.

Designations of the device and equipment "Medusa"

1, 2. - respirators (mouthpieces) of the working and reserve respiratory systems.

3. - a manual pump for pumping drainage water.

4. - manual air pump.

5. - spray can with compressed air.

6. - a collection of drainage water.

7. - seat mounting.

8, 8A - air valves.

9. - check valves of the air filling system of the compartments of the double wall of the capsule and respiratory system.

10. - locks of the "lightning" type.

11. - the valve is hygienic.

12. - a hygiene bag.

13. - seat.

14. - check valves (suction).

14A is an exhaust pressure control valve and a capsule controlled valve.

15. - exhaust check valve for the discharge of drainage water.

16. - fastening seat belts with latches for fixing the body during unrest.

17. - partitions between compartments horizontal (perimetric).

18. - fastening belts.

19. - handle (handrails).

20. - valve sleeves.

21. - loop and hook of the tongue of the seat.

22. - drainage and filling holes of ballast pockets.

23. - ballast pockets (tentacles).

23 '. - bollard (cargo) loop for bundles of grouped capsules ("Medusa"),

24. - loop for fastening the floating anchor.

Calculation of carrying capacity "Medusa"

The mushroom shape of the “Medusa” (explained) is necessary so that the capsule of the “Medusa” is not in a horizontal position, but in a more stable close to vertical position.

Reliability does not depend on the weight category of the victim, which is confirmed by the above calculation, according to the formulas Q = V _k ⋅ρ = h⋅π⋅R ² ⋅ρ, where Q is the weight of the displaced water capsule,

V is the volume of the living compartment of the capsule,

R is the radius of the outer shell of the capsule,

h is the height of the cylinder of the capsule (bottom of the capsule) ρ

ρ is the specific gravity of water,

Where h = 70 cm; R = 40 cm .; ρ = 1

Q = V _k ⋅ρ = h⋅π⋅R ² ⋅ρ = 70⋅3.14⋅ (40) ² ⋅1 = 341.68 kg.

341.68 is the weight of the displaced water, which is more than the weight of any passenger. The reliability guarantee is confirmed by calculation.

Based on the calculation result -341 kg. it can be argued that the greater the passenger’s weight, the more stable the position of the Medusa capsule.

Claims (1)

An individual life-saving protective device (ISSS) made of a durable water-repellent transparent film is a capsule of living space, which is limited by a double wall divided into non-communicating circular perimeter compartments filled with compressed air from a can of compressed air; the seat in it has a hygienic “valve”, which allows the use of a hygienic package when necessary, and on the outer lower part of the device there are ballast pockets that are necessary to maintain a stable vertical position of the capsule during unrest and at the same time being a water anchor, which reduces the speed of movement of the capsule in windy weather .
