A device for rescuing people on water and for high-speed swimming is known, characterized in that it contains two floats in the form of parallel plates of a streamlined shape, having positive buoyancy sufficient to keep a person afloat, and fixed equipment, and in the upper part of the floats are thickened, two blades in the form of cylindrical grooves, facing with a convex surface towards the bow of the floats, connecting the floats in the bow and stern parts, a U-shaped crossbar having positive buoyancy, pivotally connected to the floats, which serves as a handle for the swimmer while moving through the water, when the floats move and blades reciprocally along the surface of the water, and a footboard or a seat during the swimmer's rest on the water, and to adjust the length, the U-shaped crossbar is made of telescopic tubes with mechanisms for fixing the tubes in recessed and extended positions, for example, in the form of collet, RF patent for utility model No. 184 590, 31.10.2018.

The device is not effective enough due to the impossibility of transporting the rescued person placed on this device by the swimmer.

The problem to be solved by the claimed invention is to improve the efficiency of the device.

This problem is solved due to the fact that a device for rescuing people on the water and for high-speed swimming, characterized by the fact that it contains two floats in the form of parallel streamlined plates, having positive buoyancy sufficient to keep a person afloat and fixed equipment, two blades in in the form of cylindrical grooves, facing with a convex surface towards the bow of the floats, connecting the floats in the bow and stern parts, a U-shaped crossbar having positive buoyancy, pivotally connected to the floats, which serves the swimmer as handles while moving through the water and a footboard or seat during recreation on the water, and the guides of the U-shaped crossbar are bent, and the ends of the guides protrude above the floats, a fishtail-shaped fins connected to the guides of the U-shaped crossbar, creating a pulling force when raising and lowering the U-shaped crossbar.

The swimmer, being on the surface of the water and holding the device in front of him by the U-shaped crossbar, reciprocates with the device and floats away from the accident site. The swimmer, while pulling the device towards himself, makes a stroke. When the device is pushed off, the blades and floats float up and slide along the surface of the water. After gaining a certain speed, the swimmer can turn on the fins by lowering and raising the U-shaped crossbar. The presence of two drives in the device allows the swimmer to swim a long distance, using one of the two drives in turn. During rest or waiting for help, the swimmer is kept on the water surface due to sufficient positive buoyancy of the device, while the swimmer can stand on a U-shaped bar or sit on a fin, being in the square formed by floats and blades. The swimmer can also transport the rescued person placed on the device using fins to move.

The technical result provided by the given set of features in the device is to increase the efficiency of the device.

The figure shows the proposed device, top and sectional views. A device for rescuing people on the water and for high-speed swimming, characterized by the fact that it contains two floats 1, 2 in the form of parallel streamlined plates, having positive buoyancy sufficient to keep a person afloat and fixed equipment, two blades 3, 4 in the form of troughs cylindrical, facing the convex surface towards the bow of the floats 1, 2, connecting the floats 1, 2 in the bow and stern, U-shaped crossbar 5, having positive buoyancy, pivotally connected to the floats 1,2, which serves the swimmer as handles during movement on the water and a footboard or seat while resting on the water, and the guides of the U-shaped crossbar 5 are bent, and the ends of the guides protrude above the floats 1,2, the fin 6 in the form of a fish tail, connected to the guides of the U-shaped crossbar 5, creating a traction force when raising and lowering the U-bar 5.

The device works as follows.

A person on a shipwrecked vessel can jump into the water with their feet down while holding the device in their hands. In the presence of a life jacket, a person can first put on the vest on himself, fixing it on the body with belts and passing the leg belts between the legs. Then the person, holding the device by the U-shaped crossbar 5, takes a deep breath, holds his breath and jumps into the water. A person with the device enters the water in an upright position. In the water, due to the positive buoyancy of the device, a person cannot dive deeply into the water, which ensures a quick ascent.

A person can first drop the device into the water, and then jump and pick up the device on the water.

A device attached to an unmanned aerial vehicle can also be delivered to a person in the water in need of assistance.

While in the water, a person places the device in front of him and, holding it by the U-shaped crossbar 5, reciprocates with the device, and floats away from the ship, which is shipwrecked. Bringing the blades 3, 4 closer to him, the person makes a stroke and moves forward in the water. Pushing the device away from himself, the person applies an effort to the U-shaped crossbar 5, but much less than during the stroke. The blades 3, 4 float up and slide along the water surface due to the positive buoyancy of the floats 1, 2 and the U-shaped crossbar 5, as well as due to the fact that the blades 3, 4 are made in the form of cylindrical grooves.

To move quickly through the water, a person also works with his feet, pushing off from the water, in antiphase with the movement of the device, for example, in the breaststroke style. After gaining a certain speed, the swimmer can turn on the fins 6, alternately lowering and raising the U-shaped crossbar 5.

Having sailed away from the accident site to a safe distance, a person can wait for the rescuers, staying on the water surface due to the positive buoyancy of the device, standing on the handle lowered down the U-shaped crossbar 5, or sitting on the fin 6. A person can also sit on a belt between the floats 1, 2 if there is a belt in the device.

To save himself, a person can use warning devices, a radio beacon, a rocket launcher, a whistle and other devices, if the device is equipped with such.

In the device, the floats 1, 2 can be made of a streamlined shape from lightweight and durable materials, for example, from reinforced foam.

In the device, the blades 3, 4 and the U-shaped crossbar 5 are made of lightweight materials, for example, aluminum, titanium or reinforced plastic.

In the device, the positive buoyancy of the U-shaped crossbar 5 can be ensured due to the presence of air cavities in it or due to attached lightweight materials made of foam or foam rubber.

In the device, the U-shaped crossbar 5 may have additional handles corresponding to the physiological structure of human hands, which are not conventionally shown in the drawing.

In the device, the fins 6 can be made of an elastic and durable material, for example, rubber or polyurethane.

The device may have a belt with a lock connecting the floats and serving as a seat in the square formed by the floats 1, 2 and blades 3, 4, not shown in the drawing. Sitting on a belt and moving up and down the ends of the U-shaped crossbar 5, the swimmer can also effectively move on the device due to the work of the fin 6.

The device may have a halyard with a displacer not shown in the drawing. The rope can be used by a swimmer to secure the device to vehicles, including an unmanned aerial vehicle. A buoy can be used by a swimmer or a lifeguard to help locate the rope in the water.

The water finder can be painted with reflective or fluorescent orange paint.

The device can have attachments in the form of a navigator, a compass, a whistle, a radio transmitter, a radio beacon, a flashing beacon, a LED luminous grid, a flashlight, a rocket launcher, smoke bombs, self-igniting lights, a power source, a waist belt, a safety halyard, a life line, a knife, a life vest , wetsuit, caps, swimming masks, breathing tube, fins, food container, fresh water container, seawater distiller, sleeping bag, inflatable or foldable sleeping mattress, inflatable life floats on the arms and on the neck, inflatable tent and compressed balloon air.

The author made a model of the device and tested it in a reservoir.

Floats 1, 2 were cut from 50 mm foam sheet with dimensions 1185 × 250 mm2.

As blades 3, 4, the author used polypropylene containers from under acrylic paint with a volume of 9 liters, with a base diameter of 250 mm, a height of 220 mm and a wall thickness of 1.5 mm. The halves of the containers cut in height were folded together by their upper parts and fastened together, the bottoms of the halves were attached to the floats 1, 2. The blades 3, 4 were reinforced with stiffening ribs made of the container lids. The blades 3, 4 were set at a distance of 500 mm from each other and protruded beyond the lower edge of the floats 1, 2 by 70 mm.

U-shaped crossbar 5 was made of two fiberglass ski poles with a diameter of 14 mm and a length of 1277 mm with steel flat tips. The sticks were connected at the top of them with a wooden strip 20 × 40 × 600 mm, which served as a handle for the swimmer. The distance between the guides of the U-shaped crossbar 5 was 550 mm. Holes with a diameter of 6 mm were drilled in the steel tips of the ski poles and the poles were pivotally attached to the floats 1, 2 with bolts 6 mm in diameter at a distance of 250 mm from the center of the blades 3, 4.

In a calm state, the model lay on the surface of the water, while about a third of the blades 1, 2 were in the water.

To measure the forces that were applied to the model to move it through the water, a household dynamometer with a scale of 10 kgf and a scale division of 0.1 kgf was used.

The force during the stroke, when the model moved towards itself at a speed of 1 m / s, was 9.0 kgf, the force when the model was moved away from itself at a speed of 1 m / s was 0.3 kgf.

The test of the fin 6 in the form of a fish tail, connected to the guides of the U-shaped crossbar 5 and creating a traction force when lifting and lowering the U-shaped crossbar 5, was not carried out by the author. However, the operability of the proposed device with a fin located in front of the swimmer is evidenced by an article from the Internet: https://63.ru/text/entertainmenty888617.html, part 4, line 4. This article talks about an athlete - a submariner who swam 2 5 -meter pool with a fin in hands in 11 seconds. At the same time, the speed of movement of the swimmer was approximately 2.3 m / s, which is much higher than the speed of movement of the athlete on the water without any devices. Therefore, the fin 6 in the form of a fish tail, as the most efficient water drive, created by nature itself, in the proposed device, according to the author, should provide the maximum speed of movement of the swimmer on the water surface.

Devices can be made both in artisanal and in production conditions. For example, fins can be manufactured at the Yaroslavl Rubber Products Factory located at st. Sovetskaya, 81-a, Yaroslavl, 150003, tel. 84852584302.

Blades and U-shaped beams can be made at the "Vladimir Chemical Plant", located at: st. B. Nizhegorodskaya, 81, Vladimir, 600000, tel. 84922325242.

The floats can be manufactured at one of the eight extrusive polystyrene factories, https://www.tn.ru/about/o_tehnonikol/industrv/zavody_e_p/.

The device can be painted with reflective paint produced by Noxton or with fluorescent enamel AS-55U of Alp Enamel CJSC.

The device for rescuing people on the water and speed swimming can also be used for teaching swimming, for fun on the water and in sports.
