Description

The invention relates to reusable warning and rescue equipment for collective (life rafts, boats, boats, yachts) and individual (wetsuits, life jackets) rescue equipment, used to detect an object (person) in distress on the water and determine its location , and can be used in mass production.

Every year on the water, mainly in the sea, a large number of people die, despite the attraction of significant resources and sufficient, at first glance, provision of individual and collective rescue equipment. If there is not enough operational and reliable communication between the objects that have been disaster at sea and the means of their search, due to malfunctions in the signal and emergency equipment, a short detection distance, the decisive factor for the victims is the time, to which the second most important factor is often added - the temperature regime.

Currently, all rescue equipment at sea, as a rule, is equipped with emergency sources of light and radio signals intended for their quick search and detection. However, due to accidents unavoidable at sea, with a high probability the action of the mentioned devices is not effective enough.

An individual life-saving device is known comprising a jumpsuit equipped with a corner reflector made of a gas-tight inflatable material with a metallized coating and mounted on a gas-tight inflatable stand connected to the hydro-jumpsuit, internally reinforced with an antenna wire mesh and equipped with an etching valve (SU 472862, publ. 1975.06.05) while a signal light is installed in the upper part of the said reflector, and the composition of the metallized coating contains a bright dye, for example, Orange. The small dimensions of the reflector with a small rack height (not more than 0.5 m) provide too weak a signal that is not perceived by the radar. In addition, the known device is designed for only one person’s position, in which the corner reflector with a bulb will not be in the water, namely, on the back.

A known system related to rescue equipment for detecting a person in distress on the water, and determine its location (RU 2299832, publ. 2007.05.27). The system comprises a life-vest put on a person, equipped with two light sources, two transmitters with transmitting antennas and an energy source, as well as a receiver installed at the control point. A disadvantage of the known system is the limited operating time of light sources and radio transmitters due to the lack of recharging, as well as the need to use it in conjunction with a life suit, without which the life jacket holds a person in water in a position close to vertical, while all light and radio transmitting devices find themselves in water and become useless when looking for a victim.

Closest to the claimed is a combined alarm rescue system containing an orange-filled helium balloon with mirror stripes on the outer surface with an attached signal-transmitting device located inside a hollow cylindrical body and containing a light signal and radio transmission system, electronic circuits, controlling light and radio signals, power supply and a piezoelectric recharging system, as well as a ball and gas filling system distress signal transmissions. The said cylindrical body is connected by means of a strong thread to a container, on the top of which a glass is mounted pivotally attached to the bracket of the carrier plate, in which the system for providing power to additional devices in the form of a combined lamp with an LED, a stun gun and heating elements is placed. The system is equipped with mounting straps, through which it is attached to the human body. In case of distress, it can be used to signal and indicate the location of a person, group of persons, as well as a vehicle.

The well-known emergency rescue system is disposable, while being structurally complex and expensive. A signal-transmitting device, which includes a number of electronic circuits, a complex supplying additional devices such as a stun gun, not only complicates and increases the cost of a known system, their presence negatively affects its performance and reliability. In case of failure of the signal-transmitting device or in the event of a main power failure, the system cannot be detected from a long distance, because the radio signal reflected from the bands on the ball due to scattering has a low intensity, and the additional light signaling due to the low placement of the combined luminaire with an LED is not effective enough. It is difficult to bring the known system to working condition, which becomes almost impossible if the person in distress received a serious injury, while the constructive solution of the system to bring the ball into working condition in practice does not ensure its metered filling and preservation in the filled form. Until the ball is completely filled with helium, it is necessary to hold it for 2-4 seconds, which is structurally impossible in the known system; as a result, only a partially filled ball begins to move upward and loses contact with the gas-containing container. In addition, the calculation of the air flows that will drive the elements that ensure the performance of the piezoelectric battery recharging system is purely theoretical and in practice is likely to be insolvent. The lack of power sources jeopardizes the system’s performance, while devices such as stun guns and heating elements in wetsuits become redundant due to unacceptably high energy consumption.

The objective of the invention is to develop a comprehensive emergency rescue system that provides reliable visual detection of a distressed object by means of its search, operable at sea, efficient and at the same time easy to manufacture and use.

The technical result of the proposed integrated alarm and rescue system is to increase its reliability, efficiency and ease of use, while simplifying and reducing manufacturing costs.

Advantageously, the proposed system comprises a stationary battery or two lithium batteries with a capacity of at least 700 ampere hours each, charged by a film solar battery placed on the open surface of a rescue craft (on a tent roof, etc.)

In the proposed system, a fishing line with a diameter of 5.0 mm was used as the thread holding the ball, the free end of which is equipped with a fastener in the form of a plastic plate with two belts 1.0-1.5 m long.

The indicated technical result is also achieved by an integrated emergency rescue system for individual rescue equipment, containing a balloon with a brightly colored metallized surface, filled with gas lighter than air, mainly helium, a container containing the said gas under pressure, a starter for filling the ball with helium and bringing the system in working condition, a light alarm with an electronic control circuit, as well as power sources, a thread holding a ball, and fastenings for I hold the entire system, in which, unlike the known one, a container filled with gas under the pressure necessary to fill a ball with a diameter of at least 0.7 m is placed inside the ball, the outlet at the bottom of the container is equipped with a tube that is hermetically connected to the ball inlet wherein the starting device is mounted on the upper end of the container and is made in the form of a metal tube with a nipple installed inside it, provided with an internal thread for screwing an internal tube with an external thread into which it is inserted a rod with a piston at the lower end made with three holes for passing gas and provided with a locking ring located in the annular recess of the piston 2 mm from its upper edge, the upper end of the rod having a disk perpendicular to it, while the light signal system is located on a durable filament below the filled ball at a distance of 60-70 cm, contains a white light LED lamp with an electronic control circuit located together with a battery with a capacity of 250 ampere hours, charging from the one placed on the surface ara film solar battery in a waterproof box with waterproof pushbutton on the front side.

Mostly in the proposed system, a small-sized ROBITON Krona battery is used.

In the proposed system, a fishing line with a diameter of 3.0 mm was used as the ball holding thread in the proposed system

An integrated emergency rescue system for individual rescue equipment includes a pocket for storing it, which is placed in wetsuits and life jackets at the level of the belt and equipped with a metal mounting ring.

The drawings schematically shows a General view of the proposed system in working condition: FIG. 1 - for collective rescue equipment, FIG. 2 - for individual.

In FIG. Figure 3 shows a starting device that initiates filling the ball with gas and bringing the system into working condition.

The “collective” alarm and rescue system contains a ball 1 made of durable rubber 2 mm thick, the diameter of which is 1.4 m in a gas filled lighter than air, mainly helium state. The ball is covered with bright raspberry-colored metallized paint for visual search and search using the radar. The neck of the ball covers a tube 2 with a diameter of 25 mm and a length of 25 mm, which is equipped with the lower part of the container 3 placed inside the ball, with a height of 79-80 mm and a diameter of 39-40 mm, made of steel and containing helium under pressure, which ensures filling of the ball to a diameter of at least 1.4 The connection is fixed with adhesive tape and sealed on top with a soft aluminum tape until it is completely tight.

A fishing line 5 is attached to the end of the tube 2 using a frame 4 with a size of 25x10 mm, which holds the ball in working condition. Fishing line 5 is made of material that is used in the manufacture of gear for catching large fish. The diameter of the fishing line is 5.0 mm, the length is 14 m. For fastening the system to the boat, the free end of the fishing line is equipped with a fastener 6 in the form of a plastic plate with two straps 1.0-1.5 m long.

The power source is a stationary battery 7 with a capacity of at least 1400 ampere-hours, and if it is not available on a rescue craft, it is replaced by a lithium battery with a capacity of 720 ampere-hours of the Krona type in the amount of two pieces, provided that it is rechargeable multiple times. To recharge the battery (s) 7, a film-based flat solar battery 8 was used, placed on a suitable open surface of the rescue craft, which at the same time also serves to recharge the batteries of portable radios included in the collective rescue equipment supply kit.

Below the filled ball 1 at a distance of 60-70 cm, a plastic waterproof casing 9 of a size sufficient to accommodate a control electronic circuit that sets the operating mode of the white LED signal lamp 10 is attached to the fishing line 5. On the front surface of the housing 9 there is a waterproof start button (not shown in the drawing) that controls the power supply of the light alarm. The ball can be equipped with a backlight with a reflector for use in the dark.

To supply power from the battery 7 is a fishing line with a built-in copper wire, and the power is supplied through a resistor (not shown in the drawing).

In the upper part of the container 3, a starting device 11 is installed for supplying helium to the ball 1 and bringing the system to working condition. Starting device 11, which is shown in detail in FIG. 3, comprises a steel tube 12 5 cm long with a wall thickness of 1 mm, the lower end of which enters the container 3 in its upper part. The tube 12 with an inner diameter of 8 mm is equipped with an automobile nipple 13, which serves to inject helium into the container 3 and then fill the ball 1, and is made with an internal thread. In addition, the starting device includes a tube 14 with a length of 3 cm with an external thread, the external diameter of which is 8 mm and the internal 6 mm, made at one end with cutouts for the key, with which it is screwed into the tube 12 with an internal thread in this way so that its lower end is at a distance of 5-6 mm from the upper end of the nipple 13. In the tube 14 is a rod 15 with a total length of 50 mm and a diameter of 2 mm with a piston 16 at one end. The piston 16 is made with three holes for the release of gas and is equipped with a cut-out retaining ring 17 with a thickness of 2.0 mm, identical to automobile piston rings. To place the retaining ring 17 at a distance of 2 mm from the upper end of the piston 16, an annular cutout 2.5 mm deep is made. In a compressed state, the diameter of the circlip 17 is 6 mm.

A disk 18 with a diameter of 15 mm and a thickness of 2 mm is welded to the free end of the rod 15.

The system operates as follows.

When you press the disk 18 with a force of about 3 kg (taking into account friction), the piston 16 lowers and presses on the tongue 19 of the nipple 13, releasing helium from the container 3 into the ball 1, while the piston 16 with the retaining ring 17 moves to the bottom of the tube 14 so that the retaining ring extends beyond its limits, is released, expands and stops its further movement.

A helium-filled balloon rises into the air. The system is operational.

In normal mode, the LED lamp, in accordance with the international standard, gives 50-70 flashes of white light per minute. The ball can be detected visually or using a radar, and the backlight makes it clearly visible also in the dark.

Currently, with the help of collective rescue equipment, an object in distress at sea can be visually detected at a distance of 2-3 miles, and with the help of radio equipment for 7-8 miles. The proposed signal search and rescue system allows to increase the detection distance by almost two times.

Search and rescue signaling system for individual rescue equipment, a general view of which is shown in FIG. 2, contains a rubber ball 20 with a wall thickness of 1.5 mm and a diameter of 0.7 m in a helium-filled state. The ball is painted with bright raspberry-colored metallized paint for investment visual search, as well as search using the radar, while part of its surface is covered with a 21 film-type soft solar battery designed to recharge the battery.

The starting device 11, the container 3, containing helium under the pressure necessary to fill the balloon with a diameter of 0.7 m, the fishing line material, as well as the fastening of the ball to the fishing line are identical to those used in collective rescue equipment.

The individual search and rescue signal search system also contains a plastic waterproof case 9 measuring 10 × 5 × 3 cm, which is attached to the fishing line below the ball at a distance of 60-70 cm. The light signal system contains an LED lamp 10 - a white light source mounted above the case 9 , which houses an electronic circuit that regulates the frequency of flashes of an LED lamp (50-70 flashes per minute) and a battery with a capacity of 250 ampere-hours, mainly of the “crown” type, in particular, Robiton, which weighs 53 g and can be up to 1000 times.

The lower end of the fishing line, whose thickness is 3 mm, the length is 7 m, is attached to a metal ring in a pocket 22 for storing the system, made in wetsuits and life jackets at the level of the belt.

The individual use system is brought into working condition, without removing it from the pocket 22, using the start button on the housing 9 and the starting device 11, which act in exactly the same way as in the alarm system for collective rescue equipment.

Currently, the distance of visual detection of a person in a wetsuit or life jacket does not exceed 1.5 cable (278 meters). The proposed system allows you to detect it at a distance of 7 to 12 or more miles.

Reusable use of the proposed system in a collective and individual form is provided as follows.

The emptied container 3, which contained helium under pressure, is removed from the ball. Unscrew the inner tube 14, in which the rod with the piston is placed. The container 3 through the nipple 13 is filled with helium from a gas cylinder to the desired pressure. Then screw the tube 14 into place and pull the piston rod into it. If necessary, recharge the batteries. The container 3 with helium is installed inside the ball, the ball inlet is joined to the container outlet, inserting the container output tube 2 into the neck of the ball, and the joint is sealed.
