Description

The present invention relates to emergency rescue operations, mainly for lifting sunken submarines from any depth.

A known method of raising submarines of relatively low weight and overall dimensions of the period of the Great Patriotic War of 1941-1945 using floating cranes in whole or by cutting into parts, sections, 1.

The disadvantages of this method are as follows:

- due to the increase in weight and dimensions of the latest nuclear submarines with a displacement of 8-12 thousand tons or more, it is not possible to raise the submarine to the water surface using floating cranes, even from a relatively shallow depth;

- the country currently lacks well-equipped, maneuverable vehicles for this kind of emergency with comprehensively trained people, therefore they are forced to turn to their original enemies for help, degrading the dignity of the country and its true patriots.

The closest and comparable technical solution claimed is the application I submitted for consideration, sent to the address of the Federal Institute of Industrial Property on February 10 this year. from Samara under the name "Method of lifting sunken submarines".

Since I have not yet received priority information, I cannot refer to it. This application therefore passes the same class of MKI, which will not present difficulties to find.

The disadvantages of the previous technical solution and method of lifting a sunken submarine are as follows:

- the existing rescue ships, for example, neither Admiral Chebanenko, nor Altai, which arrived at the scene of the Kursk submarine accident, have modern means of lifting;

- in the previous application, Figures 10, 11 show a catamaran type ship that is not yet in life and cannot be mistaken for a prototype, and if this ship appears, then only from the point of view of the mooring of a submarine with a rescue ship, since the rescue ship catamaran type, its construction will require significant material costs and time, which is not permissible for today's Russia, and therefore at this stage of the country need rescue equipment, achieved with less material and human costs;

- in addition, a rescue vessel, even of a catamaran type, a hydrofoil vessel with speeds of 60-120 kilometers per hour does not solve the problems of mutual rescue of people and equipment in the 21st century, when all kinds of various types of cruise ships run in the open spaces of the oceans ships for which help is needed in critical situations. Here we need rescue ships with speeds of 400, 500 km per hour, maybe space help.

The aim of the invention is: saving people, ensuring the safety and livelihood of rescuers, accelerating the recovery of sunken ships, purposefully adapting existing ships to rescue and raising sunken ships, reducing material and labor costs.

This goal is achieved by the fact that two vessels of the same name / of the same type / preferably with large displacements / carrying capacity /, set parallel at a certain distance from each other and on one line perpendicular to the longitudinal axes of the vessels, constituting a rectangular water field between the vessels, facing each other on the deck on the bow and stern of the sides mounted slewing rings / crane /, mainly ball-bearing. On the turntable of the slewing ring on the scarf, an axis is mounted horizontally, on which a spatial truss of rectangular or triangular section is attached with the ends. Farms connect two ships / ships /. On top of the connecting truss vessels on their upper belt or inter-farm space, pedestrian bridges for people who are fenced on both sides with a railing. On the vertical axis of the pivoting circles, chasing eyebrows are made, on which challas braided at the ends are fixed. Moreover, the chal is fixed on the bow of the turntable of one vessel, the other braided end is fixed on the stern of the turntable of the second vessel. Two diagonally fixed chals create a relatively reliable triangular rigid system. To ensure the safety and security of the work of the spatial expansion trusses against torque during the longitudinal rolling of vessels, at the ends of the trusses, at the junction with the slewing ring, vertical elongated holes are made on both sides on vertical sheets.

Thus, between the vessels a water field of a rectangular or rhombic shape is formed due to the elastic deformation of the chals and their sag, which ensures the reliability of the entire system without any intrasystem stresses.

On the deck of each vessel, from two sides along the side, winches were installed at certain distances, with the help of which the spatially lifted submarine is moored. When raising a submarine, the roll of each ship is regulated by these winches, for which a roll gauge should be installed on each ship.

A new set of features will facilitate the raising of the submarine, make the work more reliable and meaningful with a significant reduction in material and labor costs.

Figure 1 shows the rescue vessels in plan / vertical projection / articulated by two expansion spatial trusses and pulled together by two diagonal chals / cable ties /;

figure 2 - types of rescue ships and a submarine, mutually moored, view along A;

figure 3 - node 1 of the turntable in plan, articulated with a spacial-truss and diagonally flexible connection;

figure 4 is a section along aa with a view of the pivot circle articulated with a spacial truss and with a pedestrian bridge.

On the rescue ships 1 and 2, on the sides facing each other, in the fore and aft parts, crane slewing rings 3 are installed, to which two spacer spatial trusses 5 with pedestrian bridges 6 in the upper zone are pivotally attached , or intra-farm space with a railing. At the ends of the trusses 5, at its end scarves, there are eyes, at the junction of the horizontal axis 4, as well as elongated vertical holes 7, made on a slewing circle with the ability to move the axis 4 along the longitudinal hole by an amount "a", which allows for large waves from the longitudinal chaotic rolling of two vessels to avoid torsional moment in the spatial expansion farm from the action of the enormous masses of the vessels themselves. On the vertical axis of the slewing ring, a chasing eye 8 is made for diagonal mooring of two vessels with chals / ropes / 9 for stiffening along the triangular most reliable system in the horizontal plane, within the longitudinal elasticity of the ropes and their sag.

Along the sides of each vessel 1 and 2, winches 10 were installed / attached / at certain distances, from where the submarine 12 was spatially moored 11 so that the rescue vessels do not roll when the submarine begins to rise or at large waves, the submarine is moored by ropes 13 from the winches to outer sides of rescue ships.

Rescue vessels themselves at relatively shallow depths, anchored / fixed / by traditional means to the ground, and at large depths for exposed buoys with ropes 14.

Two vessels with spacial spatial trusses, for example, 100 meters long, will provide a field of reliable confident operation regardless of weather conditions, while practically no one will notice the angle shift by some degrees and these changes within the elastic stretching of the ropes, as well as the lifting of the rope sag / Chalov / will not matter when raising a submarine.

The technical and economic advantages of the proposed technical solution are as follows:

- a relatively simple technical solution, turning into a very reliable rescue vehicle close to large catamaran type vessels;

- the ability to use well-established, reliable tools, such as turntables and spatial farms widely used in construction;

- since slewing rings work in a less intense mode than on construction cranes, with an angle of rotation of 3-5 degrees, it is possible to use slewing rings of decommissioned cranes, which usually go for re-melting, because the cranes are written off not from the condition of inoperability slewing rings;

- the presence of a large number of winches installed on ships also does not represent large material costs, since it is widely used in construction, transport and shipbuilding;

- interchangeable steel, nylon and ropes from other modern polymer materials and chains traditional in maritime transport can be used as chals;

- Thus, all structural elements in a single form are well-known and generally available, but in a new concrete combination, when carrying out rescue operations at sea, the ocean, a new positive effect;

- in the end result, insignificant material costs and labor costs, but a big effect on saving people, material and moral.
