Description

The invention relates to ship-lifting equipment, in particular to devices for lifting sunken submarines.

Known devices for lifting sunken submarines, consisting of grips of various designs and mates mounted on a sturdy hull of a submarine, see, for example, US Pat. Belgium No. 36906, US Pat. Of the Russian Federation No. 2222467 or rod device according to OST V5.2008-83 "Rod device. Design rules and standards".

Among them, the closest analogue in terms of simplicity of design and use technology is the rod device. This device includes a ring mounted on a strong body of the object, and a rod connected to the ring through the links. The head of the rod is equipped with a slot with a roller for fixing a guide conductor in it, with the help of which the gripper is guided and docked with the rod. In the stowed position, as well as to prevent mutual movements during the movement of the object, the rod and links are attached to the folding (tear-off) sheet of the light body of the object and to each other using tacks, while the fastening of the links should ensure their separation by up to 3 tf.

The disadvantages of this device are the rather large mass and dimensions of the rod and links, which is why they occupy an extremely scarce volume in the superstructure, and also require strengthening the hull of the boat, which in turn leads to an increase in its center of gravity and a decrease in operational characteristics. In addition, the limitation of these devices on carrying capacity does not solve the issue of raising a flooded submarine with fully flooded compartments, which reduces the possibility of its use.

A device for lifting sunken submarines, fixed to the hatches of the submarine and containing a spindle, at the lower end of which is installed with the possibility of rotation around its axis cross member. At the upper end of the device, an earring with ship-lifting brackets is also fixed on the axis. A device for fixing the cross member in a horizontal position, made in the form of a sling and a latch, is installed on the spindle body, see, for example, a mortgage device for rescue hatches of the submarine described in the "Album of typical technological maps for performing rigging and diving operations when lifting from shallow depths", Lomonosov, V. 20914, 1999. This device is taken as a prototype.

To fix this device to the submarine, no counterparts are required on its housing. However, it, like the previous analogues, has a limitation in carrying capacity and in the number of mating parts (hatches) installed on the sunken submarine hull, which also does not solve the problem of raising a flooded submarine with completely flooded compartments. The use of the device eliminates the use of a combined lifting method, when part of the lifting force is created by mechanical means, and part is due to the restoration of the buoyancy of a strong body.

The objective of the invention is to improve the tactical, technical and economic characteristics of the device for lifting sunken submarines by providing the ability to create additional lifting forces by blowing a strong hull of the submarine.

The problem is solved in that the known device for raising sunken submarines, containing a spindle, at the lower end of which a cross member is mounted to rotate around its axis, and an earring with ship-lifting brackets and a device for fixing the cross member in horizontal position is also mounted on the axis containing a sling attached to the cross member and a latch provided with a foundation fixed through the seal to the coaming of the hatch with hook bolts, with a cover provided with a rubber seal, p a safety valve, a fitting for connecting the purge sleeve and a sealing cuff in the form of an inflatable shell installed in the central hole of the cover and interacting with the spindle, and an squeeze tube is installed on the submarine's hull.

New significant features of the proposed device are the presence of:

- a foundation with a cover fixed to the coaming of the submarine hatch with hook bolts;

- a safety valve, a fitting for connecting the purge sleeve and the central hole with a sealing sleeve, made in the form of an inflatable shell mounted on the base cover;

- a squeeze pipe mounted on a sturdy hull of a submarine.

The presence of new significant features ensures the creation of additional lifting force to the device due to the purge of the submarine compartment located under the device. Thus, the introduction into the known device of the proposed parts and assemblies provides a solution to the problem of the invention.

Figure 1 shows a General view of a device for lifting a sunken submarine.

Figure 2 shows the embedded device (front view).

Figure 3 shows the embedded device (side view).

Figure 4 shows the installation of the foundation of the device on the coamings of the hatch of the submarine.

The device for lifting sunken submarines consists of a foundation 1, to which a cover 4 is attached using a bolt 3 through a rubber seal 2. A safety valve 5 and a compressed air supply fitting 6 are installed on the cover 4, to which a discharge sleeve 7 is connected during use of the device. In the Central hole of the lid 4 mounted cuff 8, made in the form of an inflatable shell. The power part of the device is a spindle 9, to the upper and lower parts of which, on the axes 10, an earring 11 with brackets 12 and a cross member 13 are connected respectively. A device for fixing the cross member 13 in a horizontal position containing a sling 14 fixed to the cross member is mounted on the spindle 9 and a latch 15. The foundation 1 is fastened to the coaming of the hatch 16 with hook bolts 17. A squeeze pipe 18 is installed in the slotted hole of the sunken submarine’s sturdy hull for water outlet from the compartment, above which there is Luke.

The device is used as follows:

After the decision is made to raise the sunken submarine using the proposed device, the development of a project for lifting work, as well as the arrival of all the assigned forces and means to the area of work, depending on the depth of the submarine’s flooding by divers or an underwater vehicle, a guide conductor is delivered to it and fixed him behind on the boat hull. Before starting work, the diver, using available means, cuts a hole in the boat's hull into which the squeeze tube 18 fed through the conductor is inserted and brewed. Then, the foundation 1 is also lowered along the conductor. After the foundation 1 is installed on the hatch 16 of the submarine, the diver fixes it with hook bolts 17 to the coaming of the hatch. Then he gives a command to the surface about the descent to the boat the power part of the device. The lowering of the power part of the device is carried out together with the lid 4, which is previously put on the spindle 9 and fixed to the earring 11. When the power part of the foundation device 1 is reached, the diver directs it inside the hatch 16. After the cross member 13 passes the lower edge of the hatch, the diver uses a sling 14 rotates it through an angle of 90 ° and fixes it in this position using the latch 15. After that, the diver, using bolts 3, fixes the cover 4 on the foundation 1, using the pressure sleeve 7 inflates the cuff 9, and then attaches it Ukawa to the nozzle 6, verifies operation of the safety valve 5 and fixes the clevis 11 on the cover 4 of the power failure of the device inside the submarine bay. After performing the above operations, the diver sharpens the device using lifting slings secured to the brackets 12. The device is ready for use. Then, along the discharge sleeve 7, compressed air is supplied into the compartment of the submarine. In this case, as the compartment is filled with compressed air, water leaves the compartment through the squeeze pipe 18. After the compartment has been drained to a predetermined volume by applying load to the ship's lifting slings, the sunken submarine is lifted to the surface or to a given step by lifting mechanisms of the supporting vessel or the ship's lifting pontoon.

The technical and economic advantages of the proposed device in comparison with the mortgage device for salvage submarine hatches described in the "Album of typical technological maps for performing rigging and diving operations when lifting from shallow depths", Lomonosov, military unit No. 20914, 1999 and adopted as a prototype, consists to ensure that the device is provided with additional lifting force due to the purging of the submarine compartment located under the device and thereby to improve its tactical and technical characteristics.

The invention is at the development stage of a technical proposal. Its implementation does not require a significant amount of research and development. The use of the invention is possible when performing specific work on lifting sunken objects.
