Description

The utility model is intended for rescuing people on the water in case of ship wrecks or accidents with the help of human muscular strength by quickly sailing away from the accident site on the device.

A source of information is known from the prior art (RF 177462, published 05/22/2017), which discloses a device for rescuing people on water and for high-speed swimming, characterized by the fact 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, while the rod with the handle allows the swimmer to perform reciprocating movements of the blade, and the blade, rod and handle have positive buoyancy (formula p. 1).

While in the water, the swimmer makes a reciprocating blade motion. Bringing the blade closer to him, the swimmer makes a stroke. The swimmer then pushes the blade away from him. The blade floats up and moves along the surface of the water with minimal resistance.

The device is not effective enough due to the high resistance when moving the blade forward directly in the water.

The task to be solved by the utility model is to increase the efficiency of the device.

This problem is solved due to the fact that a device for rescuing people on water or for high-speed swimming, characterized by the fact 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, while the blade, rod and handle have positive buoyancy, and the blade is elastic and has slots dividing the blade into equal segments, which are compressed in the water when the blade moves forward and expands when the blade moves backward.

The swimmer, being on the surface of the water and holding the device in front of him by the handle, reciprocates with the device and floats away from the accident site. The swimmer, pulling the device towards himself, makes a stroke. In this case, the blade opens up and takes up the maximum area. When the device is pushed forward, the blade, like an umbrella, folds and moves in the water with minimal resistance.

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, side view.

A device for rescuing people on the water or for high-speed swimming, characterized in that it contains a blade 1 in the form of a segmental surface of a sphere, a rod 2 fixed at one end in the center of the blade 1, a handle 3 connected to the other end of the rod 2, while the blade 1, the rod 2 and the handle 3 have positive buoyancy, and the blade 1 is made elastic and has slots 4 dividing the blade into equal segments 5, which are compressed in the water when the blade 1 moves forward and expanding when the blade 1 moves backward.

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 handle, takes a deep breath, holds his breath and jumps into the water. A person with a device, like a parachute, 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 throw the device into the water, and then jump himself and pick up the device on the water.

The device, attached to the quadcopter, can be delivered to a person in the water and in need of help.

Being in the water, a person places the device in front of him and, holding it by the handle 3, makes reciprocating movements of the device, sailing away from the ship, which suffers a shipwreck. A person, bringing blade 1 closer to him, makes a stroke and moves forward in the water. Pushing the device away from himself in the water, the person applies efforts, but much less than during the stroke, due to the fact that the segments 6 of the blade 1 are folded, the cross-sectional area of the blade 1 decreases, and the blade 1 experiences minimal resistance in the water.

To move quickly through the water, a person also works with his feet, pushing them off the water, in antiphase with the movement of the device, for example, in the breaststroke style.

Having sailed from the accident site to a safe distance, the person can wait for the rescuers, staying on the water surface due to the positive buoyancy of the device. The device is effective not only in calm but also in stormy waters. The device does not need to be lifted constantly above the water, you can swim with it completely immersed in water, periodically taking breaths, raising your head above the water.

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

The device may contain a ring lying on the outside of the blade 1, limiting the opening of the segments 5 of the blade 1.

The device can be made collapsible or folding.

In the device, the blade 1 can be made of transparent plastic, the rod 2 and the handle 3 can be made of reinforced plastic.

In the device, the positive buoyancy of the blade 1, the rod 2 and the handle 3 can be provided due to the presence of air cavities in them or attached floats made of foam or foam rubber.

In the device, the handle 3 can be made in the form of a ring or in the form of a letter L with bends in accordance with the physiological structure of human hands.

The device can have two or more blades 1 located on the rod 2 at a certain distance from each other.

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

The author made a model of the claimed device. As a blade 1, a hemisphere was used, cut off from the top of a 9-liter bottle for drinking water "Kalinov Rodnik" together with a neck at a height of 126 mm from the top of the bottle.

Producer of water "Fonte Aqua PC", 141850, Russia, Moscow region, Dmitrovsky district, Domodedovo village, st. Embankment, 21, building 2, room 85, tel. 84957405265. Bottle material - food grade polypropylene.

The result is a blade with a diameter of 185 mm. The weight of the blade with the throat was 0, 037 kg. The surface of the blade 1 was divided into 8 equal segments 5, and cuts were made from the edge of the blade 1 with a length of 93 mm.

The wall thickness at the edge of the blade 1, the top of the segments 5 was 0.2 mm, at the base of the segments 5-0.4 mm. The length of a wooden rod 2 with a diameter of 12 mm with a plastic handle from an umbrella with a diameter of 17 mm is 610 mm, weight - 0.115 kg. The total weight of the model with fasteners was 0.161 kg.

To measure the forces that were applied to the model to move it in water, a household dynamometer with a scale of 10 kgf and a scale division of 0.1 kgf was used. The weight was measured with a VITEK household electronic scale with a measurement range of 0-5 kg and an error of 1 g.

The force that had to be applied to move the model forward in the water at a speed of 1 m / s was 0.4 kgf. To move the model forward in the water at a speed of 0.5 m / s, it was necessary to apply less force, equal to 0.2 kgf. To make a stroke, to move the model backward at a speed of 1 m / s, a force equal to 1.5 kgf had to be applied to handle 3.

The author on the rod 2 at a distance of 150 mm from the first blade 1 fixed the second of the same blade. The weight of the model increased by 0.040 kg and amounted to 0.201 kg together with the fixing foam insert.

The force that had to be applied to move the model with two blades forward in water at a speed of 1 m / s was 0.6 kgf, while moving at a speed of 0.5 m / s - 0.3 kgf. When stroking, moving the model backward at a speed of 1 m / s, the force that had to be applied to the handle 3 of the device was 2.5 kgf. In order to further increase the force during the stroke, you can use a blade 1 of a larger diameter.

In a calm state, the model lies on the surface of the water, while half of the blade 1 is in the water.

The proposed device can be manufactured in artisanal conditions, as well as at factories that produce sports equipment and produce plastic water tanks.

SV-101 paint can be used as a reflective coating.

The device for rescuing people on water or speed swimming can be used in daily life for teaching swimming, water entertainment and sports.
