Description

FIELD OF TECHNOLOGY

The claimed technical solution relates to shipbuilding and for the design of vehicles on water, for example, inflatable boats.

BACKGROUND

An individual rescue tool is known (RU 134898 dated 01/10/2013), made in the form of an inflatable raft, made of light air of impermeable synthetic material. The raft consists of inflatable boards, the bottom of which is fixed to the bottom, and a protective tent on top, and a water-ballast wedge-shaped bag - keel - is attached to the bottom perimeter of the bottom. The sides are made with horizontal separation by an elastic diaphragm equipped with a check valve. The bottom is made of three layers of material of the insulated upper layer, the middle with inflatable cavities and the lower protective layer, jointly fastened and equipped with a check valve at the junction with the sides. To ensure conditions for not overturning the boat, for example, during strong waves or when launching, the awning is made with inflatable stiffening ribs, the cavity of which communicates with the cavity of the sides through the holes, and are filled with gas due to the unified pneumatic system of the boat structure.

Known hull of a catamaran boat (FR 2073213 from 09.24.1971), consisting of two inflatable cells located outside, between which there is an outer bottom fixed to them. Each of the cells in its horizontal mid-plane is grooved, separated by an airtight section. According to the description, the lower part and the upper part of the cell are made of different materials. In this case, the lower part of the cell is hermetically separated from the upper part of the cell, which provides an advantage when one of the parts is destroyed; and provides equal pressure from above and from below. The cells are interconnected (upper and lower) by bonding, stitching, knotting and vulcanization.

The disadvantages of both of the above technical solutions is the inability to use these solutions in inflatable boats, since there is no bow and transom, where the latter is designed to install a motor engine.

Also known is an inflatable boat (RU 2101208 from 12.26.1995), which, according to its closest characteristics, is taken as a prototype. The boat contains inflatable sides, as well as bow and stern ends, made of interconnected shell cutting elements in the form of round cylinders of elastic material, and a bottom attached to the sides, bow and stern ends. The boat is made with the possibility of changing the ratio between the height of the side and its width, which is implemented on one section of each side and made in the form of a horizontal elastic diaphragm located in the center of the section and attached inside the shell cutting elements along the entire length of these sections of the sides with their division into two : the upper and lower zones, equal along the perimeter of the section, and in these sections the outer surface of the side is made in the shape of a cylinder with parallel bases in the form of a closed plane algebraic crystal a cassini-type oval with a “waist” having a vertical axis and a “waist” in the horizontal plane, the distance between the vertices of the oval along its vertical axis being greater than the diameter of the base of the adjacent sections of the round cylinders, and the distance between any points of the oval located on the same horizontal less than the diameter of the base of the adjacent sections of the round cylinders, while the perimeter of the Cassini oval curve with a “waist” is equal to the perimeter of the base of the round cylinders, and the central axis of the cylindrical surface s having the form of a Cassini oval type "waist" adjacent circular cylinders coincide with the central axis. In this case, the bow and stern ends are non-working areas in all types of boats. In this design, they remain in the form of a round cylinder.

The disadvantage of the claimed prototype is the lack of a horizontal elastic diaphragm in the bow and stern ends of the boat. In addition, the horizontal elastic diaphragm located on the sides, located along the entire length, does not provide safety during navigation, since in case of damage to the lower zone, the operation of the boat becomes impossible.

The objective of the technical solution is the development of an inflatable boat with an enlarged cockpit, which provides increased safety during operation compared to peers.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The technical result of the above task is achieved by creating an inflatable boat, including the bow, aft ends, as well as an open contour of the inflatable sides, where the latter are separated by horizontal elastic section walls attached inside the shell cutting elements, along the entire length of the sides with separation into the upper and the lower zone, while the bow and aft extremities are also separated by elastic partitions, some of which are horizontal, and part are vertical, while Key Recent situated in inflatable sides. The specified technical solution ensures safety due to the formation of airtight compartments and increases the area of the cockpit of the boat, as well as increases the height of the side, which gives greater safety when on the water (protection against splashes and waves).

A technical solution is possible, where the upper and lower zones, separated by elastic partitions of horizontal section, can be uneven or uniform in volume of the area. The specified technical solution provides the possibility of varying the carrying capacity of the boat.

A technical solution is possible, where the open contour of the sides can be made A-shaped or U-shaped. The specified technical solution provides increased buoyancy of an inflatable boat, depending on the operation.

A technical solution is possible, where the number of elastic partitions of a vertical section in each of the inflatable sides can be more than one, with the formation of airtight compartments, and an air valve can be installed in each compartment. The specified technical solution ensures the safety of the operation of the inflatable boat.

IMPLEMENTATION: USEFUL MODEL

In a technical solution, the terms used include the following concepts:

A balloon is an inflatable side of a boat or an inflatable balloon.

The partition is an elastic diaphragm, vertical or horizontal section.

The bow is the front of the boat.

Cockpit - width and length inside an inflatable boat.

Shell - elements of cutting material for an inflatable boat.

Marking - this is a transfer operation, to the elements of the sheathing of lines from the drawing to indicate the places and size of the subsequent assembly of the inflatable side.

The claimed technical solution is shown in FIG. 1-7, where an inflatable boat (1) is shown, consisting of:

- a transom (4) made in a special form with the repetition of the oval of the inflatable sides (3) of the boat (1), to improve the fastening and intended for the installation of outboard motors.

- the bottom (2) of the boat (1), made in the form of an elastic bottom (2) attached to the inflatable sides (3) and the transom (4) in their lower part, creating a keel-like or other shape of the bottom (2).

- inflatable sides of the boat (3), consisting of balloons, bow (5) and representing an open contour of the sides of the A-shaped or U-shaped (see Fig. 6),

- aft ends (6), protruding beyond the transom (4) of an inflatable motor boat (1), and performing the following functions: create additional lifting force when going to planing, raise aft when moving with a passing wave, and additionally protect the outboard motor.

- horizontal partitions (7) made of the same flexible air-containing material as the inflatable sides (3) of the boat (1) and fixed in the inflatable sides (3) and the bow (5), as well as in the aft ends (6) by gluing, according to the marking applied inside the shell of the inflatable sides (3).

- vertical section walls (8) made of the same flexible air-containing material as the inflatable sides (3) of the boat (1) and dividing the inflatable sides (3) and the bow (5) into independent compartments, which makes the inflatable boat (1 ) increased buoyancy, since in case of damage to one of the compartments, the inflatable boat (1) retains buoyancy.

- an additional partition (9) made of elastic air-containing material, as well as inflatable boards (3). Mounted in inflatable sides and bow (5) by increasing the cutting of the shell and gluing, according to the markings located inside the inflatable sides (3) and provide increased load capacity of the boat. It also increases the height of the inflatable sides (3), which gives greater safety when on the water (protection against splashes and waves).

Partitions of the horizontal section (7) are attached from the beginning of the aft ends (6), and to the partitions of the vertical section (8) in the middle of the inflatable sides (3). And from the vertical section walls (8) in the middle of the inflatable sides (3) to the vertical section walls (8) in the bow (5). The gluing of partitions (7) horizontally cross-section is carried out according to the templates in the process of manufacturing the elements of the inflatable sides (3) to the vertical partitions (8) to form airtight compartments of the inflatable boat (1). The elastic partitions of the vertical section (8) are made perpendicular to the partitions of the horizontal section (7). They divide the elements of an inflatable boat (1), such as: inflatable sides (3), bow (5) into several airtight compartments from two to eight, where an air valve can be installed in each such compartment (not shown in Fig.) , which ensures the independence of each airtight compartment. And in case of damage to one of the compartments, the boat remains stable on the water surface.

The separation of the inflatable sides (3), the feed ends (6), the bow (5) into the upper and lower zones, with the help of an elastic horizontal partition (7), allows you to get both uneven and uniform in volume of the area of the zone. This feature allows you to vary the load capacity of the boat (1), for example, with an increase in the lower zone, the edges of the upper are smaller, which increases the height of the inflatable sides (3) of the boat (1). This ensures the shape of the inflatable sides (3) oval in height, which allows you to increase the cockpit, namely the internal area of the inflatable boat (1).

The inflatable boat (1) itself is made in the form of an A-shaped or U-shape and is formed by two inflatable sides (3) and a bow (5) made of shell cutting elements. The different shape of the boat (1) is associated with operation under different conditions. If you need a faster operation of the boat (1), then mainly use the A-shape. If you need increased load capacity of the boat (1) - use the U-shape.

Inflatable sides (3), bow (5), aft ends (6) are separated by elastic partitions (7) of horizontal section parallel to the bottom (2) of the boat (1).

The manufacture of the boat (1) is carried out using serial technology. When filling the inflatable boat (1) with air, the inflatable sides (3) take a given oval shape. The inflatable sides themselves (3), the bow (5) and the aft ends (6) take the form of an elongated oval in height. In this case, the inflatable sides (3) of the oval shape, allow to increase the height of the inflatable side (3) by 12% and the inner width of the cockpit by 20%.

Comparative experiments were carried out in which inflatable boats with the same technical specifications for the diameter of the inflatable sides were taken, where one of them is with a usual round side and the other inflatable boat, according to the claimed technical solution, where the latter provides a larger usable area of more than 20%.

The claimed technical solution, namely an inflatable boat, due to the introduction of sealed compartments using elastic partitions of a vertical section and due to the introduction of partitions of a horizontal section (sealed or non-sealed) across all elements of the boat, ensures safe operation, as well as an increase in the cockpit, which allows more cargo with more comfortable conditions for the owner of the boat.
