Description

The device is designed to save people on the water in the event of ship accidents or accidents due to the quick location of the device on the water and the quick departure from the place of the accident on the device with the help of muscular human strength.

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 from 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 body of the swimmer wriggles in the water, creating dangerous loads on the spine.

The electromechanical toy of the author I. Chekhomov is known, in which 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 is used as a drive in the water. 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.

The device does not have positive buoyancy 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 plates with a bow slanting from the bottom and a recess in the stern-shaped stern, having positive buoyancy sufficient to keep a person afloat and equipment fixed to them, two blades made in the form of a segmental surface of the sphere and having positive buoyancy, a manual bar connecting the floats, two rods connecting the center of the blades to the switch manual adina, characterized in that the rods are pivotally connected to the crossbar and have handles for lifting the blades above the water, and the manual crossbar is pivotally connected and allow the swimmer to perform reciprocating movements with floats and blades.

A swimmer, being on the surface of the water and holding the device in front of him by the hand rail, performs reciprocating movements with floats and blades and floats forward. When the device approaches itself, the floats and blades are immersed in water, and the swimmer makes a stroke. With the translational movement of the device, floats and blades float, and glides over the surface of the water. In this case, the swimmer does not need to raise the blades above the water. The efforts on the hands of the swimmer are distributed evenly, the spine of the swimmer does not experience unusual bending loads for him, which allows the swimmer to swim a great distance. A swimmer, waiting for help, can sit on the blades and, holding his hands on the hand rail, rest.

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, side view.

A device for saving people on the water and for high-speed swimming, characterized in that it contains two floats 1 and 2 in the form of plates with a bow slanting from below and a recess in the stern-shaped stern, having positive buoyancy sufficient to keep a person afloat, and fixed on them equipment, two blades 3 and 4, made in the form of a segmental surface of the sphere, having positive buoyancy, a manual crossbar 5 connecting the floats 3 and 4, two rods 6 and 7 connecting the center of the blades with the manual crossbar 5, I distinguish It consists in the fact that the rods 6 and 7 are connected to the handrail 5 manually and have handles 8 and 9 for lifting the blades above the water, and the handrail 5 is pivotally connected to the floats 1 and 2 and allow the swimmer to perform reciprocating movements with floats 1 and 2 and blades 3 and 4.

The device operates as follows.

A person on a shipwrecked ship can jump down into the water while holding the device in his hands. In the presence of a life vest, a person can first put it on himself, fixing the vest on the body with straps, including missing the leg straps between the legs. Then the person, placing the blades 3 and 4 of the device above his head and holding it by the handles 8 and 9, 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 the water, the canopy of blades 3 and 4 captures air, which, like floats 1 and 2, does not allow a person to dive deep into the water and provide him with a quick ascent.

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

While in water, a person places the device in front of him and, holding it with his two hands on the handrail 5, makes reciprocating movements with floats 1 and 2 and blades 3 and 4 and floats away from the shipwrecked vessel. A person, bringing floats 1 and 2 and blades 3 and 4 closer to himself and applying a certain force to them, makes a stroke with them and moves his body in the water forward to the device. Pushing the floats 1 and 2 and the blades 3 and 4 away from himself, the person also makes efforts, but much less than during the stroke. The floats 1 and 2 and the blades 3 and 4, having positive buoyancy, float and glide over the surface of the water. To turn when moving in water, a person lifts blades 3 or 4 above the water by the handles 8 or 9.

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 the domes of blades 3 and 4 under a fair wind or fair current.

If a person does not know how to swim, then in anticipation of help he can stay on the surface of the water, holding the handrail 5 by his hands, while he can sit on blades 3 and 4 to save energy.

Having sailed from a dangerous place to a safe distance, a person must wait for 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.

In the device, the floats 1 and 2 can be made of lightweight materials such as foam.

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

In the device, the blades 3 and 4, the crossbar 5 and the rods 6 and 7 can be made of titanium, stainless steel or composite materials and reinforced plastic.

In the device, the crossbar manual 5 may have bends in accordance with the physiological structure of human hands.

In the device, the blades 3 and 4 can have clamps for connecting the blades to each other in the form of buttons or clothespins in order to conveniently use the blades as a seat while the swimmer is resting on the water.

When using the device in sports, the blades 3 and 4 can be connected by a plate curved along the surface of the blades 3 and 4.

In the device, the floats 1 and 2 can be made in the form of disks, cylinders or balls.

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

The device may have attachments in the form of a navigator, a compass, a whistle, a radio transmitter, a beacon, a flashing beacon, an illuminated LED grid, a flashlight, a rocket launcher, smoke bombs, self-igniting lights, a power source, a waist belt, a safety rope, a life line, a knife, a life jacket , wetsuits, hats, masks for swimming, breathing tube, fins, food container, fresh water container, sleeping bag, inflatable or folding sleeping mattress, inflatable tent and balloon th air.

The author made a mock blade and tested it in the bathroom, filling the bath with water. A blade in the form of a segmental surface of a sphere with a diameter of 280 mm, a height of 110 mm, a weight of 230 g and a capacity of 4.8 liters was made from the top of a 30 liter plastic beer bottle. The address of Varnitsa LLC, the manufacturer of bottles: ul. Lenin, 55-a, pos. Kardymovo, Smolensk Region, 215850, Russia, tel./fax: 84816741132.

The segmental surface of the sphere was tested together with a cork and a plastic air outlet tube secured to the neck fitting on the inside of the sphere. The length of the tube is 550 mm, the outer diameter of the tube is 15.5 mm, and the tube wall thickness is 0.7 mm. The wall at the end of the segmental surface of the sphere is elastic, the wall thickness is 0.2 mm, to the center - the wall thickens and becomes solid. The tube was used as a rod. At a distance of 100 mm from the free edge of the tube, a loop of tape was made to fix the dynamometer.

To prevent the model from drowning, a ring of waterproof foam rubber with a weight of 40 g, a diameter of 170 mm, a thickness of 57 mm and a hole with a diameter of 70 mm was put on the neck outside the segmental surface of the sphere. The free end of the tube, acting as a rod, was closed by a stopper. Such a model floats on the surface of the water, while half of the segmental surface of the sphere is in the water, the tube lies on the surface of the water.

For measuring the forces, a household dynamometer with a scale of 10 kgf and a scale division of 0.1 kgf was used.

The efforts to move the specified model of the blade at a speed of 1 m / s were approximately: when moving the model forward - 0.3 kgf, back - 3.0 kgf.

Segmented surfaces of the sphere can be manufactured at the Varnitsa LLC enterprise or at factories manufacturing goods from polymeric materials, for example, MosPlast, http://www.plast.msk.ru/ or Sosnovskagropromtekhnika OJSC, www.sapt.ru/ thermoplastic.html, or stainless steel, for example, in the Nerzhavstal Shipyard, http://www.nerzhavstal.com/, St. Petersburg, or at the Metal Construction Plant, Lyubertsy, Moscow Region, http: // www. itpmet.ru/nerzhavejka.

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.
