Description

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

A device is known for saving people on the water during ship accidents or accidents, both for rescuers and for those rescued due to quick departure from the accident site, as well as for entertainment and sports purposes by providing a high swimming speed containing a float and blades made flat streamlined, made from 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 blade above the water, with the other hand make a stroke with the second blade 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 wriggles in the water, creating dangerous loads on the spine.

A device for saving people on water and for high-speed swimming is known, characterized in that it contains interconnected blade in the form of a frame, a float in the form of a plate and two handles in the form of double-bent tubes, while the ends of the tubes are fixed at the corners of the frame and the frame is held on the upper ends of the handles attached to the float, the blade contains inlet openings formed by parallel spaced rods attached to the frame, and inlet valves in the form of plates suspended on the rods from the side the arrangement of the handles for the bends formed by the plates themselves, with the possibility of free deviation from a vertical position to horizontal when the blade moves in water and from horizontal to vertical when the blade moves back, the handles allow the swimmer to perform reciprocating movements with the blade and float, and the float has positive buoyancy sufficient to hold the swimmer on the surface of the water, RF application for utility model No. 20151394423 from 09.16.2015.

The disadvantage of this device is the low efficiency of its use in water contaminated with garbage, grass and algae. Dirt can get under the inlet valves, clog the inlet openings and interfere with the effective operation of 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 water and for high-speed swimming, characterized in that it contains a float in the form of a plate having positive buoyancy sufficient to hold the swimmer on the surface of the water, two handles in the form of double-bent tubes in the form the letters C, fixed by the ends to the front and rear ends of the float and allowing the swimmer to perform reciprocating movements of the float, while the lower plane of the float is made in the form of a tread with parallel ridges and troughs located across the float, and the front slopes of the tread ridges are beveled towards the front end of the float at an acute angle, for example, at an angle of 30 degrees, and with the forward movement of the float, they slide along the surface of the water, and the rear slopes of the tread ridges are perpendicular to the plane of the float and in the return movement the float rests on water, and the float itself is tapered from the bottom towards the front end, and the rear end of the float is made perpendicular to the plane of the float and thickened.

Holding hands on the handles of the device, the swimmer holds his body on the surface of the water due to the sufficient positive buoyancy of the float. When performing reciprocating movements, the swimmer begins to swim forward. In this case, the swimmer does not need to lift the device above the water, the forces on the swimmer’s hands are distributed evenly, the swimmer’s spine does not experience oblique loads unusual for the spine, which means that the swimmer will be able to swim a greater distance. Pollution, which may be in the water in the form of garbage, grass and algae, does not interfere with the normal operation of the device, since it does not have inlet openings and inlet valves. The function of the blade is performed by the rear slopes of the ridges of the tread, made perpendicular to the plane of the float, as well as the end face of the rear float. During translational motion, the float glides over the surface of the water, as well as the contaminants in the water.

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 drawing shows the proposed device, a top view and side view.

Device for saving people on the water and for high-speed swimming, characterized in that it contains a float 1 in the form of a plate having positive buoyancy sufficient to hold the swimmer on the surface of the water, two handles 2 and 3 in the form of double-bent tubes in the form of the letter C, fixed ends for the front 4 and rear ends 5 of the float and allowing the swimmer to perform reciprocating movements of the float 1, while the lower plane of the float 1 is made in the form of a tread with parallel ridges 6 and depressions 7 located across float, and the front slopes of the ridges of the tread 8 are beveled towards the front end of the float 4 at an acute angle, for example, at an angle of 30 degrees, and with the forward movement of the float 1 slide over the surface of the water, and the rear slopes of the ridges of the tread 9 are perpendicular to the plane of the float and in the return movement the float 1 rests on water, and the float 1 itself is tapered from the bottom towards the front end 4, and the rear end of the float 5 is made perpendicular to the plane of the float and thickened.

The device operates as follows.

A person in a shipwrecked vessel can jump down in the water, after putting on a life jacket and clutching the device to his chest, or throw the device into the water and then jump into the water. While in the water, a person places the float 1 with the tread down and, holding the handles 2 and 3 from the side of the rear end of the float 5, makes reciprocating movements with the float 1 and will sail away from the shipwrecked vessel. A person bringing the float 1 closer to himself, performing a return movement of the float, makes a stroke with the rear slopes of the tread ridge of the float 9 and the rear end of the float 5. To overcome the water resistance during the return movement of the float, 1 person applies a certain force and moves his body forward in the water. Pushing the float 1 away from itself, performing a translational movement of the float 1, a person also exerts a force, but much less than with the return movement of the float, since the float glides on the surface of the water due to the small angle of inclination of the front slopes of the ridges of the tread 8 and the lower bevel of the front end of the float four.

For the effective operation of the rear end of the float 5, it is thickened. The energy of the incident wave on the rear end of the float 5 is not lost during the return movement of the float, since water due to the thickening of the rear end of the float 5 does not flow to the upper plane of the float 1.

To move in water, a person can also work with his feet, pushing them from the water, for example, in the style of a breaststroke, in antiphase with the movement of the float 1.

If a person does not know how to swim, then he must hold on to the handles 2 and 3 of float 1 to be at the surface of the water. A person can hold onto float 1 itself or lie on it. A person who does not know how to swim should wait for rescuers when they come to his aid. If necessary, a person can turn on a beacon and other means of detection, for example, use a whistle or a flashlight, if equipped with a device.

In the device, the float 1 may be made of foam or foam.

In the device, the float 1 can be made hollow or inflatable.

For ease of transportation, the device can be made folding or collapsible.

In the device, the handles 2 and 3 at the ends of the float 4 and 5 can be mounted pivotally with the possibility of their fixation. This property of the handles 2 and 3 will allow you to set them in a position in which a particular swimmer will experience less hand strain. As clamps, you can use collet clamps (not shown in the drawing).

In the attachment device for the handles 2 and 3 on the front end of the float 4 can be made at a distance less than at the rear end of the float 5, in order to ensure the convenience of holding and fixing the device on the back of a person for parts of the handles 2 and 3 located at the front end of the float 4.

For ease of operation in the device, the handles 2 and 3 can be made with bends in accordance with the physiological structure of human hands (not shown in the drawing).

In the device, the handles can be made in the form of the letter G and attached only to the rear end of the float (not shown in the drawing). This version of the device is less complicated to manufacture, takes up less space during transportation, and this model will also be more efficient in contaminated water, but less functional in saving people on the water. With this option, to carry the device on the back, it should be equipped with shoulder straps, like a backpack.

To increase the buoyancy of the entire device, its handles 2 and 3 can have positive buoyancy.

In the device, the backs of the tread ridges of the float 9 can be chamfered at an acute angle toward the front end of the float 4, for example, at an angle of 60 degrees. According to the author, the float will interact with a larger mass of water, so the swimmer’s efforts will increase when performing the return movement with the blade and, accordingly, the swimmer’s movement speed on the water may increase.

In the device, the protector on the float 1 can be made in the form of plates attached to the float and repeating the position of the front slopes of the ridges of the protector of the float (not shown). This version of the device can show higher speed properties, but it will be traumatic.

To facilitate the search on the water, the device can be painted with reflective or fluorescent paint.

To increase the life support of a person in distress, the device may have attachments in the form of a navigator, compass, whistle, radio transmitter, radio beacon, flashing light, flashlight, power source, waist belt, two leg belts, safety hinge, knife, life jacket, hats , swimming masks, breathing tube, food container, fresh water container and inflatable or folding mattress.

So, if the device has a waist belt, two foot belts (not shown in the drawing), a person can leave the shipwrecked vessel together with the device on the back. To do this, a person puts the device on his back, for this he passes his hands under the handles 2 and 3 of the device and places the bends of the handles on the shoulders located at the front end of the float 4, fastens the waist belt on the belt and the foot straps on the legs in the groin area and jumps into the water with a soldier feet down.

While in the water, a person removes the device, unfastens the waist belt and foot straps, places the float 1 with a tread on the water and, holding the handles 2 and 3 on the back of the float 1, makes reciprocal movements with the float and floats away from the vessel shipwreck.

If a person does not know how to swim, then he does not need to remove his device. He must wait for the rescuers when the rescuers come to the rescue.

The author made a model of the device and tested it in the bathroom, filling the bathtub with water.

The author made a model of float 1. For this, a tread perpendicular to the side of the sheet with a height of ridges 6 of 30 mm and a width of the front bevel of ridges 8 was 60 mm on a foam sheet 210 × 280 × 50 mm ³ in size on one plane. The rear part of the ridges 9 was perpendicular to the plane of the float. The weight of the float was 0.050 kg. The weight of a screw for measuring forces screwed in the center of the float as a hook for a dynamometer was 0.014 kg. The weight of the model was 0.064 kg.

To measure the forces that must be applied to the float model 1 when moving it through the water, a household dynamometer was used with a scale of 2 kg and a scale division value of 0.1 kg.

The efforts to move the float model 1 with the above dimensions, placed on the water, at a speed of 1 m / s, were: when moving the float forward - 0.1 kg, back - 1.2 kg. The size of the proposed device in kind will be about 4 times larger in area than the model. When moving such a float I in water with a length of 560 mm, 420 mm wide, 50 mm high, with that 50 mm thick and with the same tread with a speed of 1 m / s, the forces will increase by 4 times and amount to: with the forward movement of the float 1- 0.4 kg, with a return movement of the float 1-4.8 kg.

According to the author, with an increase in the height of the float 1 and the height of the ridges of the tread 6, in the presence of a thickening of the rear end of the float 5, the forces applied to the device for moving the swimmer may increase.

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.
