Description

The invention relates to shipbuilding, in particular to docks.

Known floating structure, consisting of pontoons and a set of modular units, which is intended for use in closed bays of the seas, on rivers and lakes as a room for cultural, administrative, and industrial purposes, as well as for the placement of garages, shops, factory shops and other floating objects , see patent No. 2043253 of 09/10/1995. The disadvantages of this analogue are the difficulty of re-equipping this structure for use for another purpose, for example, as workshops for the repair of various ships, as well as e lack of ability to use it in the open sea.

Known cruise ship dock according to patent No. 2085433, published on July 27, 1997, the closest technical solution to the claimed invention, comprising a docking chamber, movable gates for closing the docking chamber, ballast compartments equipped with kingstones and ventilation valves, adjustable support devices for wearable ships, as well as a compressed air system connected by pipelines to the ballast compartments through pressure valves. The design of this docking vessel is sufficient for small-displacement vessels when transporting them to operating points for operation in the open sea, but it is not at all suitable for receiving larger displacement vessels, such as submarines, and even more so for repair and loading and unloading operations.

The technical result of the invention is to increase the operational qualities of the ship dock, consisting of:

- to reduce the time of entry-exit operations and increase the reliability of fixation of the wearable vessel in the dock chamber,

- to increase the reliability of the ballast system,

- in ensuring the accelerated repair work and handling operations,

- in the automated provision of a wearable vessel with energy resources, ammunition and vital material supplies for the subsequent operation of the vessel in an autonomous mode.

The technical result is achieved by the fact that the docking vessel containing the docking chamber, movable gates to close the docking chamber, ballast compartments with kingston and ventilation valves, adjustable support devices for wearable vessels, a compressed air system, which is trunked to the ballast compartments via pressure valves, is equipped retractable stops centering the wearable vessel in the dock chamber, the remote control system of entry and exit mechanisms and the installation of wearable vessels in the working position inside the dock chamber, a lifting bridge installed above the docking chamber with the ability to move along it, as well as a complex of lifting mechanisms that provide repair work and the acquisition of equipment for wearable objects, in particular submarines.

The aim of this invention is the provision of a full range of works, both repair and recovery, and loading and unloading for submarines that are autonomous navigation in the open sea or in conditions of non-equipped basing.

For this purpose, the design of the docking vessel is made in such a way that the ballast compartments are the right and left sides of the docking vessel, the slipway deck is its bottom, the movable gates and the ends of the ballast compartments form the stern end, and in the fore part of the vessel there is a superstructure, in which ship-dock control systems placed a remote control system for the operation of the mechanisms of entry and exit and installation of the wearable vessel in the working position inside the dock chamber, production and repair services, support services, fuel filling full-time complex, storage for ammunition, as well as rehabilitation facilities for the crew of a wearable vessel. Above the docking chamber, a flip bridge is mounted moving along it, and in the aft and bow parts of it there are boom-type load-lifting mechanisms.

The movable gates of the docking chamber, unlike the prototype, are double-winged, which reduces the time of the process of opening or closing them.

When a submarine enters the docking chamber to set it into working position, mobile support devices are provided that serve as a lodgement along the entire length of the boat, and retractable stops mounted on the dock walls of the ballast compartments, centering the object and rigidly fixing its position relative to the diametrical plane of the docking chamber. All operations and the operation of mechanisms during the approach, exit and installation of the wearable vessel, in particular the submarine, are carried out and controlled by a remote control system.

The complex of load-lifting mechanisms necessary for carrying out repair and restoration work and ammunition loading and unloading operations is located above the dock deck and includes a drawbridge, as well as boom-shaped cargo cranes installed on both sides in the aft and bow parts of the dock chamber

To carry out lifting operations along the entire length of the wearable vessel, the drawbridge is made with the possibility of longitudinal movement above the docking chamber, and the mounting ends of the bridge are equipped with locking (fixing) devices in each of its working positions. To ensure unhindered passage and installation in the working position of the wearable vessel in the dock, the bridge is made lifting with the possibility of rotation in a vertical plane relative to the attachment site of one of its mounting ends on the dock chamber. In the stowed position, the bridge closes the upper extremities of the vessel walls, increasing the rigidity of it and the entire structure as a whole.

Each of the arrow-shaped cargo cranes is rotatable relative to the vertical axis to be secured to the docking chamber in the stowed position.

A distinctive feature of the docking vessel according to this invention is the inclusion in its complex load-lifting mechanisms located in the bow of the superstructure of the vessel, a device for the rapid loading of torpedo tubes of a submarine.

To ensure guaranteed reliability of the ballast system of the docking vessel in the autonomous mode of its operation, in addition to the compressed air system in each ballast compartment, duplicate operation of the filling-drainage system of pumps connected to sea water was installed. The compressed air system is equipped with quick couplings with external consumers, in particular with the ship’s high-pressure air system (VVD) of the served submarine.

The technical solution of the proposed invention is presented:

figure 1 - General view of the ship dock from above;

figure 2 is a section along aa of the ship dock (in the plane of the frame);

figure 3 - the position of the ship dock relative to the waterline at different stages of immersion and ascent when entering and exiting and setting the working position of the wearable vessel.

The ship-dock contains (Fig. 1) a hull 1, the sides of which are formed by ballast compartments 2, and the aft end is movable gates 3, the space between the sides forms a docking chamber 4, on the supporting elements 5 (Fig. 3b) of the slipway 6 the mooring 7 (Fig. 1) and the lateral retractable stops 8 center the wearable vessel 9. On the ballast compartments 2 above the docking chamber 4 there is a flybridge 10 with an axis of rotation 11 and a locking (fixing) unit 12, as well as cargo cranes 13. In front superstructure is located device 14 loading torpedo tubes ( UBZ), while the premises of the docking vessel with ammunition storage, service devices and UBZ are separated from the docking chamber by a sealing flap 15. A hatch 16 is provided in the bow of the hull for docking with ammunition.

In each of the ballast compartments 2, kingstones 17 (Fig. 3a) and ventilation valves 18 are installed, with ventilation valves 18 located in the upper part and kingstones 17 in the lower part of the ballast compartments 2. The vessel is equipped with remote-controlled pumps (not shown in the drawings) associated with sea water to fill-drain each ballast compartment.

A compressed air system (not indicated) is organized in hull 1 of the docking vessel, including a source of compressed air and a main pipeline system with pressure valves and exits to the ballast compartments 2.

In the bow of the ship dock is a superstructure 19 (Fig.1, 2), which houses all the services necessary for maintenance, repair and equipment of a wearable ship, in particular a submarine, as well as a control system, including remote, work serving ballast compartments of systems, a complex of power equipment, as well as hoisting mechanisms.

The operations of input and output of a wearable vessel on a ship-dock are as follows.

In the initial position, the ballast compartments 2 (fig.3b) are mostly dry, kingstones 17 (figa) are closed, the ventilation valves 18 are open, the movable gate 3 is closed.

When preparing a docking vessel for receiving a wearable vessel 9, in particular a submarine (PL), by command (program) of a processor unit (not shown) that controls the sequence and duration of opening of the kingstones 17, the ballast compartments 2 and the docking chamber 4 are filled by gravity partially with water (Fig. 3a), the docking vessel is sunk on an even keel and without bank. The movable gate 3 is open. With closed kingstones 17 pumps, the ballast compartments are filled with outboard water, the docking chamber 4 by gravity is also filled with water to a level that allows the submarine 9 to enter it (Fig. 2) with movable gates 3 open.

The submarine is in the docking chamber: moorings 7 are pulled “in a stretch” (Fig. 1), the processor unit instructed to partially discharge the water by gravity through kingstones 17 with the ventilation valves open, the docking vessel floats up and the submarine “lands” on the supporting elements 5 (figb), mounted on the slipway deck 6. Retractable stops 8 finally center and fix the submarine in the dock chamber 4.

Then, taking into account the readings of the roll and trim sensors (not indicated), according to the control program determined by the processor unit, water is removed from the ballast compartments 2 (Fig.3b) (if necessary, the VVD can be used to quickly drain the ballast compartments), a docking vessel pops up, the submarine occupies a working position in the dock chamber for repair and restoration work and ammunition equipment. Water from the docking chamber 4 leaves through an open gate. Then they close.

After performing routine and unloading and loading operations with the valves 18 open (Fig. 3a), the program opens the sliding gates and Kingstones 17. Water by gravity partially fills the docking chamber and ballast compartments 2 (Fig. 3a). For the final flooding of the docking vessel with closed Kingstones 17 and open ventilation valves 18 with pumps, water is supplied to the ballast compartments (Fig. 2). The submarine may exit the docking chamber.

To carry out the above work on the upper part of the ballast compartments 2 above the docking chamber 4 installed:

- jump bridge - crane 10. To pass the submarine, it is made rotatable relative to axis 11 and with the possibility of longitudinal movement along the vessel. For its fixation in the working position and marching made nodes pin 12;

- cargo cranes 13 arrow-shaped design installed with the possibility of rotation relative to the vertical axis of their fastening and placed in pairs on both sides of the dock chamber 4 in the aft and fore ends.

To change the ammunition of the submarine in the bow of the dock, behind the sash 15, which is sealed from the docking chamber 4, a quick loading device 14 is placed, which through the breakwaters and front covers of the torpedo tubes of the submarine (loading axes are shown in Fig. 1) loads previously received on the ship Dock through the hatch 16 and distributed by internal transportation devices on the trays on the shelves of ammunition. Ammunition with the help of carriages is introduced into the TA (not shown in Fig. 1). To exclude ammunition from the loading line, additional support trays 20 are provided.

Simultaneously with loading the ammunition can be carried out such operations on the equipment of submarines, such as:

- recharging batteries;

- supply of VVD to the ship system;

- check, recharge and alert the hydraulic system;

- repair of protective anti-acoustic surface coating of submarines;

- checking the performance of sonar systems;

- checking the operability of steering devices, propulsion system;

- loading with supplies of fuel, food and other vital consumables.

Thus, the positive effect of the proposed invention "Ship-dock" is:

- a qualitative reduction in the preparation time for submarines for a military expedition;

- the possibility of servicing submarines in the absence of coastal base infrastructure near patrol sites;

- the secrecy of service operations;

- saving resource boat systems and equipment;

- the possibility of transporting submarines in shallow water, rivers, canals, etc .;

- the possibility of alternately servicing several submarines with one ship dock.

The presence in the superstructure of the docking vessel of developed household infrastructure - living quarters, power supplies, health and fitness gyms, communications, etc. - allows you to quickly make a change in the crew of the submarine.

The proposed docking vessel provides improved quality and reduced time and cost of commissioning, including firing range.

The ship dock can also be equipped with the necessary weapons for self-defense.
