Abstract

A heeling and trim system of underwater vehicle contains cisterns located in the stern and nose, from the port side and starboard side in the light hull of underwater vehicle, connected together by piping with pumps and locking elements. The cisterns are divided by elastic membranes into upper and lower cavities. In the upper cavity the elements of positive buoyancy are placed in the form of durable spherical balls filled with light gas. The cisterns in the upper part are equipped with funnel-shaped branch pipes, they are connected by piping for durable spherical balls between them, and in the lower part -by piping with locking elements and pumps. In this case, the lower parts of the cisterns are filled with liquid.

Description

Description of the invention

The tilt-differential system refers to ocean engineering, in particular to systems for controlling the spatial position of submarines and devices.

It is known about the water roll-differential system of the underwater vehicle | see Fig. 9.20, and on p. 250 in the book

Hauks G. Underwater technology. - L.: Sudostroenie, 1979. - 288 p.), which contains water tanks connected to each other by pipelines with pumps. However, this system is placed inside a strong case, taking up a lot of space, and the mass of such a roll-differential system takes away from the device a certain share of useful 70 carrying capacity. It is not applicable for deep-sea equipment, since compressed air for depths below 5000 meters is not used due to the high pressure at depth.

It is also known about the roll-differential system of the underwater vehicle of the "Mermaid" type | see Fig. 9.21 on p. 252 in the book Hauks G. Underwater technology. - L.: Shipbuilding, 1979. - 288 p. This system is housed outside a sturdy housing and contains battery packs along with boxes that move on hinged brackets. However, in the 72 design, this system is complex and cumbersome, and the mass of the batteries together with the boxes reaches 10-1595 of the water tonnage of the device, and when moving, they provide the hull with very significant differentiating moments. That is, this system does not provide smooth adjustment of roll and trim change.

The closest in terms of technical essence, essential characteristics and the positive effect that is achieved to the claimed system is the tilt-differential system | see Fig. 9.20, d on p. 251 in the book Hauks G. Underwater technology. - L.: Sudostroenie, 1979. - 288 p.), which contains tanks filled with mercury and connected to each other by pipelines with pumps that displace mercury from one tank to another with oil under pressure. The mercury roll-differential system is located inside the strong body of the underwater vehicle, takes up relatively little space, but this system reduces the useful carrying capacity of the underwater vehicle and, in addition, having mercury in a closed volume is dangerous for people and the environment.

The basis of the useful model is the task of improving the roll-differential system, in which the use of the modernized roll-differential system ensures the leveling of the underwater vehicle, the creation of additional positive buoyancy without changing the weight of the underwater vehicle and its useful load capacity, and also ensures environmental safety.

The task is solved by the fact that the roll-differential system of the underwater vehicle, which contains tanks located in the stern and bow, on the left and right sides, in the light body of the underwater vehicle, "9 are interconnected by pipelines with pumps and shut-off elements, according to in a useful model, the tanks are divided by elastic membranes into upper and lower cavities, and elements of positive buoyancy are placed in the upper cavity in the form of hollow ceramic or glass balls filled with light gas, while there are tanks in the upper part equipped with funnel-shaped nozzles, connected by pipelines to each other, and in the lower part - pipelines with shut-off elements and pumps, and the lower parts of the tanks are filled with liquid.

The positive effect is achieved by the fact that the roll-differential system of the underwater vehicle has tanks divided by elastic membranes into upper and lower cavities, and in the upper cavity there are elements of "positive buoyancy" in the form of hollow ceramic or glass balls filled with air or other light gas, for example , helium, while the tanks in the upper part have funnel-shaped nozzles connected to each other by pipelines for strong hollow balls, and in the lower part - a pipeline with c" closing elements and pumps, and the lower parts of the tanks are filled with liquid: oil or seawater, which allows the underwater vehicle to occupy the necessary spatial position. Thus, the improved roll-differential system increases efficiency and expands the technological capabilities of the underwater vehicle, and the use of elements of positive buoyancy makes it possible to reduce the mass of the roll-differential system by two times. o The essence of the useful model is explained by the drawings: Figure 1 shows the layout of the roll-differential system in the hull of the underwater vehicle; Fig. 2 shows the layout of the roll-differential system in the hull of the underwater vehicle, side view; Fig. 3 shows the layout of the roll-differential system in the hull of the underwater vehicle, top view; so 20 in Fig. 4 shows a diagram of a tank with elements of positive buoyancy.

The roll-differential system of the underwater vehicle 1 contains tanks 2, 3, 4, 5, located in the stern and bow from the left and right sides in the light body 6 of the underwater vehicle 1. They are connected to each other by pipelines 7, 8 with pumps 9, 10, 11, 12 and closing elements 13. Tanks 2, 3, 4, 5 are divided by elastic membranes 14 into upper 15 and lower cavities 16 (Fig. 4), and in the upper cavity 15 there are elements of positive 29 buoyancy in the form of strong hollow balls 17 ( for example, ceramic or glass), filled with a light gas (air or other light gas, for example, helium), while the tanks 2, 3, 4, 5 in the upper part have funnel-shaped nozzles 18, connected to each other by pipelines 7 for strong hollow balls 17. The lower parts 16 are connected by pipelines 8 with closing elements 13 and pumps 9, 10, 11, 12, and the lower parts 16 of tanks 2, З, 4, 5 are filled with liquid 19. 60 Spherical hollow ceramic aggregates are used as elements of positive buoyancy ( see Bugaenko

B.A., Gal A.F. Methods of lifting sunken objects using lifting modules made of solid hollow fillers. Shipbuilding. 1993. Mo10. - with 11-14). As a liquid in the lower part of the tanks, oil or seawater is used.

The roll-differential system of the underwater vehicle works as follows. because in the event of roll or trim of the underwater vehicle 1 in the tanks 2, 3, 4, 5, located in the stern and bow on the left and right sides in the light housing 6 of the underwater vehicle 1, oil or outboard water is supplied to the lower cavity 16 through pipelines 8. Tanks 2, 3, 4, 5 are divided by elastic membranes 14 into upper 15 and lower 16 cavities. In the lower part 16, tanks 2, C, 4, 5 are connected to each other through pipelines 8, through which liquid 19 is pumped using pumps 9, 10, 11, 12 through closing elements 13. Liquid 19 presses on elastic membranes 14 and displaces elements of positive buoyancy in the form of strong hollow balls 17. Elements of positive buoyancy 17 through funnel-shaped nozzles 18 and pipelines 7 for strong hollow balls 17 move from one tank 2 or Z to another 4 or 5, from port to starboard, from stern to nose, creating an excess positive buoyancy on the corresponding side or stern. Thus, the underwater vehicle 1 changes its 7/0 spatial position.

The positive effect is achieved by the fact that the roll-differential system of the underwater vehicle has tanks with elements of positive buoyancy placed in them, which create additional positive buoyancy without changing the weight of the underwater vehicle and its useful carrying capacity, and also contributes to environmental safety. Thus, the improved roll-differential system increases the efficiency and expands the technological capabilities of the underwater /5 device, and the use of positive buoyancy elements allows you to reduce the weight of the roll-differential system by two times compared to the prototype.
