Description

The device is designed to save people on the water in the event of ship accidents or accidents due to the quick departure of the device from the scene of the accident using the muscular strength of a person.

A device is known for saving people on the water in case of ship accidents or accidents, both for rescuers and for those rescued by quickly leaving the scene of the accident, as well as for entertainment and sports purposes by providing a high swimming speed, containing a float and blades made flat, streamlined, made of materials such as polystyrene foam or flexible spring plates such as foam rubber, additional blades of a bucket or funnel shape are installed next to the blades, RF patent No. 2494913.10.10.2013.

The disadvantage of this device is its complexity and inefficiency. A swimmer with one hand should raise one lobe above the water, with the other hand make a stroke with the second lobe in the water, and spend a large amount of energy to lift the blades to the surface of the water. In this case, the efforts on the hands of the swimmer are distributed unevenly, the swimmer's body bends in the water, creating dangerous loads on the spine.

Known electromechanical toy author Chekhomov I., century. which as a drive in water uses a package of plastic hemispheres connected by a rubber band and located at a certain distance from each other due to the presence of bushings located between the hemispheres. When the package is stretched from hemispheres, water enters the space between the hemispheres. When the packet is compressed from hemispheres, water exits from the hemispheres, creating reactive thrust. Source: Internet, website: http://www.freshdesigner.ru/watertechnics-014.htm.

The disadvantage of this device is its low efficiency due to the large hydrodynamic resistance created by hemispheres that are constantly in water in a submerged state.

In addition, the device does not have a positive buoyancy sufficient to keep a person afloat.

The problem to which the invention is directed is to increase the efficiency of the device.

This problem is solved due to the fact that the device for saving people on the water and for high-speed swimming is characterized by the fact that it contains two floats in the form of parallel streamlined plates with positive buoyancy sufficient to keep a person afloat and fixed equipment, and in the upper parts of the floats are thickened, two blades in the form of cylindrical gutters facing a convex surface towards the bow of the floats, connecting the floats in the bow and in the stern, U-shaped a crossbeam with positive buoyancy, pivotally connected to the floats, serving as a swimmer’s handle during movement on the water, when the floats and blades move reciprocally along the surface of the water, and the footboard or seat while the swimmer is resting on the water, and to regulate the length of The shaped crossbar is made of telescopic tubes with mechanisms for fixing the tubes in recessed and extended positions, for example, in the form of collets.

A swimmer, being in the water and holding the device in front of him by the U-shaped crossbar, moves the floats and vanes back and forth along the surface of the water and moves forward. When the device approaches itself, the swimmer makes a stroke, while the floats and blades are immersed in water. When pushing the device away from itself, during translational motion, floats and blades float and glide over the surface of the water. With such movement on the water, the efforts on the swimmer’s hands are distributed evenly, the swimmer’s spine does not experience unusual bending loads, which allows him to swim a great distance. A swimmer, waiting for help, can stand on the U-shaped crossbeam or sit on it, being in the device, as in a lifebuoy formed by floats and blades.

The technical result provided by the given set of features in the device is to increase the efficiency of the device when saving a person on the water.

The figure shows the proposed device, a top view and side view, in section.

A device for saving people on the water and for high-speed swimming is characterized by the fact that it contains two floats 1 and 2 in the form of parallel streamlined plates with positive buoyancy sufficient to keep a person afloat and fixed equipment, moreover, two are thickened in the upper part of the floats blades 3 and 4 in the form of cylindrical gutters, facing a convex surface towards the bow of the floats 1 and 2, connecting the floats in the bow and in the stern, U-shaped crossbar 5 having a polo life buoyancy, pivotally connected to floats 1 and 2, serving as a swimmer’s handle during movement on water, when the floats and vanes move reciprocally along the surface of the water, and by a footrest or seat while the swimmer is resting on water, moreover, to regulate the length of the U-shaped The crossbar 5 is made of telescopic tubes with mechanisms for fixing the tubes in recessed and extended positions, for example, in the form of collets.

The device operates as follows.

A person on board a shipwrecked vessel can jump down into the water, holding the device by the U-shaped crossbeam 5, having previously increased its length to the maximum value. In the presence of a life vest, a person can first put the vest on himself, fixing the vest on the body with straps, including missing the leg straps between the legs. Then the person takes a deep breath, holds his breath and jumps into the water. A person with a device enters the water in an upright position. In water, the device does not allow a person to plunge deeply into water due to its positive buoyancy and provides a person with a quick ascent.

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

While in water, a person holds the device with both hands on the U-shaped crossbeam 5, places it on the water in front of him so that the bulge of the blades 3 and 4 are directed forward and partially immersed in water, makes a reciprocating movement of the device and floats away shipwrecked ship. A person, approaching blades 3 and 4 to himself and applying a certain effort to them, makes a stroke and moves his body in the water forward to the device. Floats 1 and 2 and blades 3 and 4 during the stroke are immersed in water. Pushing the device away from itself, a person also exerts a certain force, but much less than during a stroke. Floats 1 and 2, together with blades 3 and 4, having positive buoyancy and streamlined shape, float and glide over the surface of the water.

To increase the speed of movement in water, a person also works with his feet, pushing them from the water in antiphase with moving the device, for example, in the style of a breaststroke.

A person can use the device as a sail, substituting blades 3 and 4 under a fair wind or fair current.

Having sailed from the scene of the accident to a safe distance, a person must wait for the rescuers using the available warning equipment. To do this, a person can turn on the beacon or use other means of detection, if equipped with a device.

If a person cannot swim, then while waiting for help he can stay on the surface of the water, being in the device, as in a lifebuoy formed by floats 1 and 2 and blades 3 and 4, standing or sitting on the U-shaped crossbeam 5.

U-shaped crossbar 5 has positive buoyancy, which allows you to quickly find the crossbar on the water.

In the device for adjusting the length of the U-shaped crossbeam 5 is made of telescopic tubes with mechanisms for fixing the tubes in recessed and extended positions, for example, in the form of collets, is not conventionally shown in the drawing. The U-shaped crossbeam 5 of the maximum length is used by the swimmer during movement on water. The U-shaped crossbeam 5 of reduced length is used by the swimmer as a step or sitting while resting on the water.

The swivel joint of the U-shaped crossbar 5 with the floats 1 and 2 provides a horizontal position of the floats 1 and 2 and the blades 3 and 4, which is a necessary condition for the effective operation of the blades 3 and 4 while the swimmer is moving through the water.

To ensure effective immersion of the blades 3 and 4 in the water and their ascent, the floats 1 and 2 are thickened in the upper part, conventionally not shown in the drawing.

In the device, the U-shaped crossbeam 5 may contain additional handles, curved in accordance with the physiological structure of the human hands, is not conventionally shown in the drawing.

In the device, the floats 1 and 2 should be made of light and durable materials, for example, of reinforced foam.

In the device, the floats 1 and 2 can be made hollow or inflatable.

In the device, the U-shaped crossbeam can have positive buoyancy due to the presence of air cavities in them or due to the attachment of lightweight materials such as foam.

In the device, the blades 3 and 4 and the U-shaped crossbeam 5 can be made of and durable materials, for example, duralumin, titanium, stainless steel or reinforced plastic.

In the device, a removable lifebuoy may be attached to the floats 1 and 2 from above, not shown conventionally in the drawing. The presence of a lifebuoy in the device will increase the stability of the swimmer during his rest on the water. A swimmer can share a lifebuoy with another person who needs help.

The device can be painted with reflective or fluorescent orange paint.

The author made a model of the claimed device and tested it in the bath. Blades 3 and 4 in the form of a cylindrical gutter were made of a plastic pipe with a diameter of 120 mm, a length of 260 mm and a wall thickness of 2 mm. The pipe was cut in half along the axis, and the pipe halves were bent in hot water to a size of 140 mm between the edges of the cuts.

The blades 3 and 4 were located from each other at a distance of 205 mm and offset into the lower part of the floats 1 and 2 at a distance of 10 mm from the bottom and recessed into them to a depth of 15 mm. As floats, foam plates were used, manufactured by Technoplex, with a size of 48 × 212 × 468 mm3. On the 212 mm side, the floats were narrowed from the outside to a size of 16 mm. The floats were located at a distance of 230 mm from each other. Blades 3 and 4 and floats 1 and 2 formed a rectangle in the layout with an internal hole of 230 × 205 mm2.

The fastening of the floats 1 and 2 to the blades 3 and 4 was provided by screed tape 50 mm wide across the floats in their middle part. In the middle of floats 1 and 2 at a level of 80 mm from the bottom, a duralumin tube was installed with a diameter of 9 mm, an inner diameter of 4 mm and a length of 280 mm with an M5 thread at the ends of the tube, for which a U-shaped crossbeam 5 was pivotally fixed with its ends outside the floats 1 and 2. The U-shaped crossbeam 5 was made of polyethylene pipes with a diameter of 16 mm and a wall thickness of 0.8 mm, a length of 541 mm, from the ends muffled with foam, and a duralumin tube with a diameter of 9 mm, an inner diameter of 4 mm and a length of 280 mm with thread M5 at the ends of the tube.

The weight of the layout with mounting steel bolts and washers was 460 g.

To measure the forces arising when moving the model on the surface of the water, we used a household dynamometer with a scale of 10 kgf and a scale division of 0.1 kgf, which was connected to the U-shaped crossbar 5.

At the model in calm water, blades 1 and 2 were immersed in water to a depth of 40 mm.

The efforts to move the model along the surface of the water at a speed of 1 m / s were approximately: when moving the model forward - 0.3 kgf, back - 5.0 kgf.

Blades 3 and 4 in the form of cylindrical gutters can be manufactured at factories that manufacture goods from polymeric materials, for example, MosPlast, http://www.plast.msk.ru/ or OJSC Sosnovskagropromtekhnika, www.sapt.ru/thermoplastic .html, or stainless steel, for example, in the Nerzhavstal Shipyard, http://www.nerzhavstal.com/, St. Petersburg.

The U-shaped crossbeam 5, containing telescopic tubes with a mechanism for fixing the tubes in the recessed and extended positions in the form of collets, can be made of medical canes or Nordic walking poles bought at medical equipment stores or sporting goods.

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

The device can be manufactured in artisan workshops.

The device can be used in professional activities of a person, in sports, for games and entertainment on the water, as well as for swimming training.
