Description

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

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 of the two blades above the water, and with the other hand make a stroke with the second blade, and spend a large amount of energy on lifting the blades and holding them above the surface of the water. In this case, the efforts on the hands of the swimmer are distributed unevenly, the swimmer’s body wriggles in the water, creating dangerous loads on the spine, and the swimmer’s legs do not participate in the process of moving through the water.

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

A device for saving people on the water and for high-speed swimming is known, characterized in that it contains a blade in the form of a segmental surface of a sphere, a rod fixed at one end in the center of the blade, a handle connected to the other end of the rod, and the rod and handle allow the swimmer to perform reciprocating movement of the blade, and the blade, rod and handle have positive buoyancy, patent of the Russian Federation for utility model No. 177462, 02.26.2018.

The device is not efficient enough. The device cannot keep the swimmer afloat while waiting for help and relaxing on the water. The device has a limited swimmer’s travel speed due to the presence of only one blade in the device.

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 blades in the form of segmental surfaces of spheres located one after another at a certain distance, a rod connecting one center of the blade to one end, the crossbar, attached perpendicular to the other end of the rod and serving as handles, while the ends of the bar are bent in accordance with the physiological structure of the human hands and allow the swimmer to move the bar, the rod and the blades are reciprocating, and the crossbar, rod and blades have a positive buoyancy sufficient to keep a person afloat.

A swimmer, being on the surface of the water and holding the device in front of him by the bar, makes a reciprocating movement of the device and floats away from the scene of the accident. When the swimmer moves the device back, pulling it towards itself, makes a stroke. With the translational movement of the device, the blades float and glide over the surface of the water. Due to the presence of two blades in the device, a larger mass of water is involved in the process of movement of the swimmer than when using one blade, so the speed of movement of the swimmer through the water increases. At the same time, the efforts on the hands of the swimmer are evenly distributed, the spine does not experience unusual bending loads for it, which allows the swimmer to swim a great distance. During rest or while waiting for help, the swimmer is held on the surface of the water due to the sufficient positive buoyancy of the device.

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, side view.

A device for saving people on the water and for high-speed swimming, characterized in that it contains two blades 1 and 2 in the form of segmental surfaces of spheres located one after another at a certain distance, a rod 3 connecting one center of the blade 1 and 2, the crossbar 4, attached perpendicular to the other end of the rod 3 and serving as handles, while the ends of the crossbar 4 are bent in accordance with the physiological structure of the human hands and allow the swimmer to move the crossbar 4, rod 3 and lobes 1 and 2 backwards stupid, moreover, the crossbar 4, the rod 3 and the blades 1 and 2 have a positive buoyancy sufficient to keep a person afloat.

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 the vest on himself, fixing it on the body with straps and skipping leg belts between the legs. Then a person, holding the device by the ends of the crossbar 4 and placing the blades 1 and 2 above his head, takes a deep breath, holds his breath and jumps into the water. A man with a device, like a parachute, enters the water in an upright position. In water, due to the positive buoyancy of the device and due to the fact that the domes of the blades 1 and 2, capturing air, increase the positive buoyancy of the device, all this does not allow a person to plunge deeply into water and provides him 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 the water, a person places the device in front of him and, holding it at the ends of the crossbar 4, makes reciprocating movements with the device, and floats away from the ship, shipwrecked. A person, approaching blades 1 and 2 to himself, makes a stroke and moves forward in the water. Pushing away the device from itself, a person makes efforts, but much less than during a stroke. The blades 1 and 2 float and glide over the surface of the water due to the fact that they are made in the form of segmental surfaces of the spheres, and due to the positive buoyancy of the entire device.

For fast movement on water, a person also works with his feet, pushing them off the water, in antiphase with moving the device, for example, in the style of a breaststroke.

Having sailed away from the accident site to a safe distance, a person can wait for rescuers, holding on the surface of the water due to the positive buoyancy of the device, holding on to the rod 3 of the device, and when the device is located vertically, a person can stand on the crossbar 4.

If a person does not know how to swim, then in anticipation of help he can stay on the surface of the water due to the positive buoyancy of the device.

For his salvation, a person can use warning equipment. To do this, the person turns on the beacon, uses a rocket launcher, a whistle and other means of detection, if equipped with a device.

Due to the presence of two blades 1 and 2 in the device, a larger mass of water is involved in the process of movement of the swimmer through water than when using only one blade, and the speed of movement of the swimmer in water also increases.

In the device, the crossbar 4 can have a flat streamlined shape and can be made in the form of a wing with a thickened bow and a narrowed stern.

In the device, the crossbar 4, the rod 3 and the blades 1 and 2 can be made of light materials, for example, aluminum, titanium or reinforced plastic.

In the device, the positive buoyancy of the crossbar 4, the rod 3 and the blades 1 and 2 can be achieved due to the presence of air cavities in them or due to attached floats made of lightweight materials such as foam or foam.

The device can be made collapsible or folding, and the rod 3 can be made sliding. The ability to reduce or increase the length of the rod 3 can be used by the swimmer to select the optimal length of the rod 3 when moving on water or while the swimmer is resting on the water when the swimmer is standing on the crossbar 4.

The device may contain more than two blades. With an increase in the number of blades in the device, more than two, the effort exerted by the swimmer to move on water will increase, and, accordingly, the speed of movement of the swimmer on water will increase.

In the device at the ends of the crossbar 4 can be installed two rods 3 with blades 1 and 2, which should also lead to an increase in the speed of movement of the swimmer through the water.

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 lifeboats a lifeline bracers and neck, inflatable tents and compressed air cylinder.

The author made a mock device and tested it in a stream.

As blades 1 and 2, the author used segmental spheres with a diameter of 290 mm, a height of 116 mm, a weight of 235 g and a capacity of 5.0 l each, made from the top of 30 l of plastic beer bottles without disassembling the valve mechanism. Segmental spheres have fittings with a diameter of 15 mm and a length of 43 mm passing through the center of the blades. The wall thickness of the fittings is 2 mm. In the valve cover of the blades 1 and 2, holes were drilled in the center of the fittings with a diameter of 5 mm.

Beer and bottle manufacturer: Varnitsa LLC, address: ul. Lenin, 55-a, pos. Kardymovo, Smolensk Region, 215850, Russia, tel./fax: 84816741132.

As the core 3, the author used two aluminum tubes. One tube with a diameter of 11 mm and a length of 850 mm from the ski pole with a pressed steel nut M5 at its lower end instead of the tip, another tube with a diameter of 9 mm and a length of 280 mm and M5 thread at its ends.

A long tube from the side of the pressed-in nut was inserted into the nozzle of the blade 1 from the inside to the stop with the valve cover. In this pressed-in nut, a steel pin M5 36 mm long was pre-screwed onto 18 mm and fixed with another nut M5. After connecting the long tube to the vane 1, a short tube was wound onto the pin, which pressed the vane 1 to the long tube. A blade 2 was put on the other end of the short tube and secured to this tube with a 20 mm steel screw M5.

In order for the model to have positive buoyancy, tubes made of waterproof foam rubber with an outer diameter of 80 mm were put on and fixed in advance on the part of the rod 3.

The length of the model was 1145 mm.

The total weight of the model assembly without a crossbar was 750 g.

The buoyancy of the model was 5 kgf.

In a calm state, the model lies on the surface of the water, with approximately half of the blades in the water.

To measure the forces that need to be applied to the model for its movement through water, a household dynamometer with a scale of 10 kgf and a scale division of 0.1 kgf was used.

The efforts to move the model placed on water at a speed of 1 m / s were: forward, when lifting blades 1 and 2 from water from a submerged state - about 0.6 kgf, while sliding blades 1 and 2 through water - 0, 3 kgf, back, during the stroke - 6.0 kgf.

From information from the Internet,

https://en.wikipedia.org/wiki/%D0%A1%D0%BF%D0%B0%D1%81%D0%B0%D1%82%D0% B5% D0% BB% D 1% 8C% D0% BD% D1% 8B% D0% B9_% D0% BA% D 1% 80% D 1% 83% D0% B3

To keep afloat one person in the inventive device, the positive buoyancy should be 14.5: 2 = 7.25 kgf. To ensure a model of such buoyancy, a device made of waterproof foam rubber with an external diameter of about 100 mm should be used in the device or the length of the rod 3 and, correspondingly, the length of the waterproof foam rubber tube with a diameter of 80 mm should be increased.

As the crossbar 4, you can use the steel bar from the handlebars of a children's bicycle or the duralumin bar from the handlebars of an adult bicycle. As the rod 3, you can use an aluminum tube from ski poles. You can buy ski poles and a horizontal bar from the handlebars in sports stores.

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.

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.
