Description

An invention (a group of inventions) relates to shipbuilding, specifically to vessels that satisfy the needs of surface and underwater tourism, as well as providing research of the aquatic environment and the bottom to depths of about 50 m.

A well-known ship complex, including a carrier vessel and a floating cabin installed on it with the possibility of separation, launching equipment, propulsion devices, power supply and life support equipment: see patent RU 2170690 C1, IPC B 63 V 35/42, priority from 05.25.2000 - analogue of the invention. The functionality of this well-known ship complex is very limited: it can be used mainly for cleaning and tripping operations in the water area.

A ship complex is known, including a catamaran with side floats and a pilothouse mounted on top, an inhabited underwater vehicle suspended in the space between the floats, launching equipment, propulsion and steering devices, power supply and life support equipment: see patent RU 2026233 C1, IPC B 63 V 35/76 , priority from 05/07/1991 - an analogue of the invention. In this famous ship complex, intended mainly for underwater tourism, the inhabited underwater vehicle is suspended from the catamaran by means of swing rods controlled from hydraulic mechanisms. Such a suspension determines the structural complexity, cumbersomeness and high cost of a well-known ship complex. The very large dimensions of this complex also limit its operational capabilities. In addition, the inhabitants of the underwater vehicle were assigned the role of passive participants in the expedition, since the descent, ascent, and movement of the underwater vehicle are controlled from the surface catamaran.

A ship complex is known, including a catamaran with side floats, a felling installed above them, an inhabited underwater vehicle located in the space between them, which is suspended from the catamaran by means of a cable-winch system mounted on it controlled from an underwater vehicle; propulsion and steering devices; means of energy supply, life support and communication: see copyright certificate SU 1801865 A1, IPC B 63 V 35/73, priority dated 02.11.1990 - prototype of the invention. The device of this ship complex, designed for coastal sea tourism, does not provide for the possibility of assembly - disassembly of the complex into separate structural parts and details during operation, which limits the functionality of the complex and does not allow transporting it by road. These shortcomings of the well-known ship complex are exacerbated by its large dimensions; the complex and its components are complex and expensive to manufacture, as well as to operate.

Known omitted underwater vehicle, including a platform equipped with nodes for mounting the suspension system of the device to the carrier vessel; suspension system controls; a passenger seat attached to the platform with an air bell in the form of a movable transparent cap; a system for supplying a respiratory medium with an onboard balloon; movers: see French patent application 2583707, IPC B 63 C 11/44, priority from 06.24.1985 - an analogue of the invention. This well-known lowered underwater vehicle is notable for the simplicity of the device because it is designed to accommodate one passenger using his physical strength to drive the winch-gate and muscular propulsion-steering devices located on the device itself (ordinary oars). However, this simplicity of the analogue apparatus was achieved at the expense of the safety of using it. It is also obvious that the functionality of the specified lowered underwater vehicle (in particular, the depth of immersion) is very limited.

Known drop-down underwater vehicle, including a diving bell-loaded cabin for passengers diving from a carrier vessel, nodes for attaching a vehicle's suspension system to a carrier vessel, a breathing medium supply system with an onboard balloon, ballast means, electric propulsion devices for horizontal movement and turning of the apparatus, means Suspension system and propulsion system controls: see US patent 3800722, NKI 114 / 16R, priority from 09/28/1971 - an analogue of the invention. This well-known submersible underwater vehicle has a complex and heavy construction, expensive to manufacture. The device is designed for experienced users, which are professional divers, and does not meet the needs of surface and underwater tourism.

Known omitted underwater vehicle, including a platform equipped with nodes for mounting the suspension system of the device to the carrier vessel; seats for passengers with a diving bell attached to the platform in the form of a movable transparent cap; a system for supplying a respiratory medium with an on-board cylinder and with means for connecting to a source located on a carrier vessel; control panel for the suspension system and the joint movement of the apparatus and the carrier ship; ballast weight; means of audio and video communication with a carrier vessel: see US patent No. 4276851, NKI 114/313, priority of 08/10/1979 - prototype of the invention. In the construction of this known lowering underwater vehicle, a vertical telescopic stand fastened to the platform is provided, which is moved in the roller support elements by the cable of a ship's winch. Thus, the maximum immersion depth of the apparatus is limited by the length of the rack and is only a few meters, which limits the functionality of the apparatus. They are also limited by the difficulty of passengers leaving the apparatus under water for autonomous navigation due to the uncomfortable cap that prevents exit; in addition, the lower edge of this hood does not reach the chest of an adult passenger, which poses a threat to life. These serious disadvantages of the known lowered underwater vehicle are exacerbated by its very complex and expensive design. It provides for the connection of the apparatus to the carrier vessel in the production environment of the manufacturer, which also complicates the operation of the known lowered underwater vehicle and limits the possibility of its transportation.

The invention solves the technical problem of comprehensive improvement of the ship complex and the lowered underwater vehicle: expanding their functionality, improving operational characteristics, reducing manufacturing costs, along with ensuring high reliability and safe use.

- the seat is made with the possibility of lowering and / or folding the seat for the convenience of the underwater exit of passengers from the apparatus and return to it.

A technical result is expected from the implementation of the invention, which coincides with the essence of the problem being solved.

The invention is illustrated using figures 1-10:

- figure 1 is a General view of the ship complex in one of the working provisions;

- figure 2 represents a part of a General view of the ship complex according to figure 1 on a larger scale;

- figure 3 represents the device of the bottom-trough (figure 1, pos.13);

- figure 4 represents the ship complex in transport position;

- figure 5 represents, on a larger scale, place A in figure 2;

- Fig.6 represents a ship complex in the configuration of a houseboat on floats;

- Fig.7 is a General view of the lowered underwater vehicle (Fig.1, pos.3);

- Fig.9 is partly a system of supplying a respiratory environment for a lowered underwater vehicle;

- figure 10 represents one of the possible designs for the platform of the lowered underwater vehicle (Fig.7, pos.20).

For illustrative purposes, the relative scale for individual elements in the figures is not observed.

From the presented illustrations it is clear that the proposed ship complex is made collapsible. According to figure 1 and figure 2 it consists of three detachable from each other the main structural elements: wheelhouse 1, catamaran 2 and inhabited underwater vehicle 3 (shown in surface and underwater positions).

The catamaran, in turn, is made collapsible, with inflatable sectional side floats 4 and 5; the preferred design includes individual bags that are embedded in a flexible collapsible enclosure placed inside a precast metal frame (usually composed of titanium pipes). The floats are interconnected by truss, rod or other cross-links. From the bow and stern above the floats, sections of the trellised deck 6a and 6b are installed, and lockers 7a and 7b are fixed. They serve as additional power elements for connecting the floats, and during ground transportation of the ship complex, lockers are in the wheelhouse (see below).

In Fig. 1, the detachable wheelhouse 1 is shown afloat, being connected to the catamaran 2 by means of a ladder 8 and braces 9. In a preferred embodiment, the wheelhouse structure contains, for the convenience of viewing, transparent (from acrylic or other plastic) surfaces 10, 11 and 12 mounted in front (on the door side), behind and in the cabin, respectively. To prevent the penetration of water into the cabin, it is placed in a waterproof bottom-trough 13, preferably with inflatable sides to provide additional buoyancy. Shown separately in FIG. 3, the bottom trough is provided with loops 14 at the top of the perimeter for threading the holding cable, which covers the wheelhouse. Transparent windows-inserts 15 (for example, of acrylic material), which correspond to transparent surfaces in the deck floor, can be glued to the bottom of the trough bottom; this allows you to observe the underwater world from the inside of a houseboat. The design of the bottom-trough, together with the materials used, allow folding or folding the bottom-trough for ease of transportation.

Figure 1 and figure 2 shows that the inhabited underwater vehicle 3 is placed in the space between the floats of the catamaran, being suspended from it by means of a cable-winch system. It includes electric winches 16-19 mounted on a catamaran with cables 16a-19a, which are attached to the ends of the platform 20 provided for in the design of the underwater vehicle. Along the edges of the platform from the side of the floats are transparent cabs 21 and 22 with seats 23 for passengers. Removable wheels 24 are mounted near the cabs on the platform. They can be carried out at the level of well-known technical solutions; in a specific design, on each side of the platform, a pair of wheels is mounted on a common triangular frame with a sleeve at the top, which is mounted on its axis on the platform. Thanks to the wheels, the platform serves as a trailer for the land transportation of the ship complex by car.

In this case, as shown in FIG. 4, a drawbar 25 is connected to the platform 20 for picking up by a car, and the deckhouse 1 is installed on the platform. It is comparable in size to the underwater vehicle and has openings 26 closed in the floor, with elevated above platform 20 cabs. In the cabin there are parts of the collapsible structure of the catamaran and other structural elements of the ship complex, as well as various equipment and gear. For the convenience of stacking all these items, a pair of the aforementioned portable lockers 7a and 7b each with a transverse dimension of the catamaran is provided.

After the trailer is delivered to the place, the cabin 1 is removed on hands (by four people) from the platform 20, and after proper release of the interior space, the cabin can serve as a residential building. If desired, it can be made floating, as shown in figure 1. Here lockers taken out of the cabin are mounted above the floats in front and from the stern of the assembled catamaran. At the same time, the ramp 27 of the collapsible structure is mounted on top of the floats in the form of two racks perpendicular to the floats with a crossbar attached by screws 28: see Fig. 5. The racks are built rollers 29, which serve as a support for the cabin. The ramp-frame is attached by the free ends of the uprights to the float 4 by means of hinge assemblies 30a and 30b. On the opposite side, the ramp frame is angled by the heels 31a and 31b mounted on the float 5. In the gap between it and the ramp of the ramp frame there is an inflatable mat 32, which is initially (as shown) in the folded state.

When filling the mat can be carried out lateral descent of the deckhouse to the shore or (as shown in figure 1) launching with mooring to the catamaran. Located on its stern outboard motor 33 provides movement of a houseboat. The presence of the ramp frame makes it easy to install the cabin on the floats and implement a houseboat in the configuration, respectively, Fig.6; stretch marks 34 attach the cabin to the catamaran.

In both versions of the use of the cabin as a houseboat, the inhabited underwater vehicle 3 is located in the space between the floats 4, 5 and forms a surface-submarine vessel together with the catamaran. In the surface position, the transparent cabs 21 and 22 rise above the floats in order to provide passengers with an overview. When diving, transparent cabins also provide the necessary protection for passengers.

The ship complex is equipped with energy and life support facilities. As shown in FIGS. 1 and 2, in addition to the electric cable winch system, a compressor 35 can be placed on the catamaran (driven by a gas motor or electric accumulator) and connected to a hose 37 wound on a drum 36. Air is supplied through this unwinding hose for breath of the inhabitants of the underwater vehicle. In order to communicate with the personnel of the catamaran and chopping, the ship complex includes appropriate means of audio and video communication. In particular, a rotary camera with its control from an underwater vehicle can be mounted on a catamaran. It belongs to the class of lowered devices and can have a diverse design.

Figure 7 shows a General view of the lowered underwater vehicle, which can be used as part of the described ship complex, and in other surface-underwater floating means. According to the above description, the lowering underwater vehicle includes a platform 20 immersed from the vessel with seats 23 located along the lateral sides, which are surrounded by transparent cabs 21 and 22. They are caps open from the bottom, made, for example, of acrylic or other durable plastic. The platform is formed by a set of longitudinal and transverse extended elements: by means of pipes 41, 42. The seats are attached to the lateral longitudinal middle pipe 38 and side pipes 39 and 40, which are connected to the pipes by means of trusses 43 with axles 44 in which the said caps are mounted for rotation. When they are tilted up (see the line image), passengers can comfortably sit in chairs from the platform. For the convenience of passengers, there are also 45 steps on farms opposite the seats.

In a specific embodiment, the underwater vehicle shown in Fig. 7 is designed for four passengers, for which two rows of seats with combined backrests are provided. A common hood is mounted above each of these rows, which is tilted along the apparatus (since the aforementioned axis 44 is oriented transversely). On Fig shows the design of the apparatus, in which individual seats 21a and 21b are mounted over the seats, reclining across the apparatus. The edges of the lowered hoods are in the area of the passenger belt. When diving the underwater vehicle, the caps allow you to visually observe the environment and provide protection for the torso of passengers. If necessary, legs can also be protected.

It is envisaged that passengers are seated in chairs underwater without breathing masks, since the caps hold air according to the diving bell principle. In order to prolong the time spent under water, it is possible to supply air to the caps through a hose from an external source: for example, from the ship supply system described above with a supply hose 37 (which is not shown in Fig. 7 so as not to clutter the image). Its free end, as shown in Fig. 9, is connected to a valve block 46 located on the platform 20, from which air hoses 47 and 48 are connected to the caps. In a specific embodiment, they are laid along the tubular elements of the platform and attached to them. This system of supplying air from the carrier vessel, not shown in FIG. 7, is supplemented by a backup system, which includes a balloon 49 with a breathing medium located on the platform and connected to passenger mouthpieces 50 mounted inside the caps (one of them is shown). A backup breathing system is provided in case of emergency. In Fig. 7 and Fig. 9, only some exemplary elements of the system for supplying the underwater apparatus with the breathing medium are shown: the necessary wiring of the hoses with control valves and connections inside the individual subsystems and between them can be performed at the level of known technical solutions.

From figure 1 and figure 7 it is seen that at the ends of the platform 20 are provided rings 51, through which the lowered underwater vehicle is attached to the suspension system to the carrier vessel. This system (preferably containing ship winches with cables) keeps the apparatus on and under water. To ensure horizontal travel and turns of the apparatus on the platform mounted onboard electric motors propelled by electric current. The best embodiment shown in Fig. 7 provides for a bow thrusters propeller 52 horizontally mounted under the platform and symmetrically positioned aft screws 53, 54. The bow unit is mounted to rotate around a vertical axis, and the aft units are arranged and mounted so that they can operate in modes of forward or reverse and idle (that is, creating driving forces in opposite directions). It is possible to power the propellers of the lowered underwater vehicle both from the ship’s power supply system and from on-board means, namely from an electric battery (not shown) located on the platform. It also supplies the necessary lighting equipment (searchlights) and signal lights for the apparatus.

Platform 20 serves as a working platform for a professional diver, and here bench 55 can be mounted for him. The diver plays the role of an instructor accompanying passengers and ensuring their safety. The diver is at the same time an operator: he monitors the operation of the equipment of the underwater vehicle, controls its immersion depth and horizontal movements; The remote control 56 located on the platform serves these purposes. Instead of this stationary remote control or along with it, a remote control held in the hand can also be provided.

The omitted underwater vehicle is equipped with (not shown) audio and video communications. With their help, passengers can communicate with each other and with an accompanying diver, and he also communicates with the personnel of the carrier vessel. From said console 56, a rotary camera mounted on the carrier vessel can be controlled connected to a television monitor mounted on the platform 20. This allows you to coordinate the movement of the surface carrier vessel with the movements of the lowered underwater vehicle; in a preferred embodiment, it is provided that the surface vessel is towed by an underwater vehicle. A television camera can also be mounted on its platform for transmitting underwater images on board the carrier ship.

Obviously, for the implementation of the described control and communication functions, a cable network with corresponding connections to the cable network of the carrier vessel is provided as part of the lowered underwater vehicle. This network can be performed at the level of known technical solutions and include electrical and fiber optic lines.

In the submerged position of the lowered underwater vehicle, passengers are able to leave their seats for independent swimming, and to facilitate exit (and return passengers to the machine), the seats can be performed with the possibility of lowering and / or folding the seats. (This is especially easy to do with the above-mentioned seats with combined backrests). Swimmers can use autonomous scuba gear and masks, connected via hoses to the airborne breathing apparatus.

The design of the lowered underwater vehicle provides for the presence of ballast cargo in it, the value of which can be easily changed in accordance with the specific loading of the device. The role of the ballast weight is performed by transverse force elements in the platform 20, the amount of which can vary before the device is immersed. An embodiment of such a platform is shown in FIG. 10. Here, the longitudinal pipes are equipped with fittings 57 into which transverse pipes are inserted, provided with annular grooves 58. Split rings 59 are inserted into them and are held by union nuts 60. The middle longitudinal pipe 38 has fittings on both sides and the longitudinal longitudinal pipe 39 (and and pipe 40) - on the one hand; holes 61 are made on the opposite side. Through them, if necessary, you can remove and insert any transverse pipe without disassembling the entire structure of the platform.

The lowered underwater vehicle can be transported behind the car: for this, removable wheels 24 are fastened to the platform 20 from the side of the seats, which were discussed in the description of the ship complex. A platform with wheels can also serve as a trailer for transporting parts or the entire carrier vessel. When suspending a lowered underwater vehicle to it, the wheels can be removed or remain in place.

The above description of the ship complex and the lowered underwater vehicle gives an idea of their functioning. To this we note that the catamaran included in the ship complex is portable. The catamaran is collected on the shore, then drifted in shallow water, lowered to the underwater vehicle previously brought there and attached to the catamaran. Similarly, the assembly of the lowered underwater vehicle with another carrier vessel can be carried out.

Presented in figure 1-10, the device of the ship complex and lowered underwater vehicle does not exhaust the essence of the invention; eg:

- felling can be performed mainly both from plastic and wood, can have different shapes and contain side windows;

- the rectangular (or close to that) shape in plan is preferred, but not required for the underwater vehicle platform;

- the said platform is not exclusively recruited from pipes: rods or power elements of a different shape can be used instead;

- caps in the underwater vehicle can be movable, as well as with the possibility of quick removal - installation;

- seats together with caps and frame 43 can be performed as independent assembly units, with the possibility of undocking from the platform, in which case they can be transported on it, as well as transporting a disassembled underwater vehicle on board surface ships;

- nodes for mounting the underwater vehicle to the suspension system can have a diverse design, etc.

The above description confirms the technical result expected from the implementation of the invention: the proposed ship complex and the lowered underwater vehicle have very wide functional capabilities, are convenient in operation, inexpensive to manufacture, and are highly reliable and safe to use.
