Description

The utility model relates to devices designed to seal openings in the underwater part of a ship’s hull, and, mainly, can be used to prevent sea water from entering the ship’s hull when replacing a sonar antenna, echo sounder, absolute lag, and the like.

Known patch for sealing holes in the hull (ed. Certificate. USSR No. 1735115). It contains a rigid body made in the form of a plate, on one side of which an elastic shell is attached, forming a cavity with the plate. The cavity through the hole communicates with the drainage channel and the outboard space.

This patch cannot be used to seal a hole on the outside of the ship's hull, as it is fixed with a jack mounted on the inside of the ship.

There is also known a device for sealing holes in the hull (ed. Certificate. USSR No. 1475851). It contains a hard patch with soft sides and a waterproof panel connected to it via flexible connection, which, due to external hydrostatic pressure, is drawn into the emergency compartment and isolates it from the outboard water. Such a design does not allow installation of any nodes in the hole from inside the compartment.

Also known sealing device (ed. Certificate. USSR No. 1763287). It contains a plug, a means of sealing and fixing it on the outer side of the ship’s hull, made in the form of a connecting element placed along the perimeter of the plug, and a depressurization mechanism, made in the form of an elastic tube placed inside the connecting element, communicating with a source of compressed air.

Using this device to install a sonar antenna will require subsequent cleaning of the bottom surface of the vessel from the connecting element. Otherwise, the connecting element adhered to the bottom of the vessel around the hydroacoustic antenna while the vessel is moving

worsen the contact of the antenna with water due to the formation of vortices, which will reduce the efficiency of the sonar system.

Closest to the claimed utility model is a sealing device (patent No. 40987 RU). It contains a flat or bowl-shaped plug of a predominantly round shape made of solid material. By means of flexible connections around the perimeter of the plug means are fixed for its fixation, made in the form of permanent magnets. A sealing means is attached to the plug, made in the form of a toroidal element made of porous rubber or an air-filled rubber chamber or chamber with porous rubber glued to its clamping surface. Additionally, at least two lugs for safety liner cables are attached to the plug.

This utility model cannot provide sealing of a hole in the underwater part of a vessel if its bottom is not made of ferromagnetic alloys, such as aluminum or wood.

The technical result, which is achieved by the claimed utility model, is to ensure the fixation of the plug with the means of its sealing on the bottom of the vessel made of non-ferromagnetic materials.

To achieve the technical result, a sealing device containing a plug, a means of sealing it, made, for example, in the form of a toroidal element made of porous rubber or an air-filled rubber chamber and attached to the plug through flexible couplings of permanent magnets, is equipped with additional permanent magnets or electromagnets placed on the bottom of the vessel from its inner side above the corresponding permanent magnets attached to the cap and oriented relative to eniyu to the latter opposite lane.

Distinctive features of the proposed sealing device from the prototype is the presence of additional permanent magnets or electromagnets mounted on the bottom of the vessel from its inner side, oriented by opposite poles with respect to the poles of the corresponding permanent magnets attached to the plug.

Due to the magnetic forces arising between the pairs of permanent magnets located on both sides of the bottom of the ship’s bottom, reliable fixation is provided on the bottom made of non-ferromagnetic material

the stub vessel with its sealing means, which ensures the achievement of the above technical result.

To increase the magnetic forces, it is advisable to use electromagnets as additional magnets, which are installed on the bottom of the vessel, preferably on its inner side and oriented with opposite stripes with respect to the poles of the corresponding permanent magnets attached to the plug.

In order to increase the usability of the sealing device, additional magnets or electromagnets replacing them are fixed on a ring-shaped, having a radial cut, rubber element.

The inventive sealing device is illustrated by drawings, where

in figure 1. - shows a General view of the sealing device from the outside of the bottom of the vessel;

figure 2. - additional magnets or electromagnets fixed in the holes of the annular element, view from the inside of the vessel;

figure 3. - section along aa of figure 1 and bb of figure 2 after installing the nodes on the bottom of the vessel.

The device comprises a plug 1, to which, through flexible ties, for example, rubber bands 2, permanent magnets 3 are attached. The plug 1 contains ears 4 for securing the hinge wires (not shown).

Additional permanent magnets 5 are placed in the holes of the annular element 6 made of an elastic material, such as rubber, and having a radial cut 7. Instead of permanent magnets 5, electromagnets can be installed.

In the area of the lower hole of the clinket 8 (Fig. 3) of the hydroacoustic antenna 9, a sealing means is placed between the plug 1 and the bottom of the vessel 10, which is a mountain elastic element mounted on the plug, made in the form of an air-filled rubber chamber 11 with porous rubber glued to its clamping surface 12. (figure 2)

Operate the sealing device as follows. Before replacing the sonar antenna of the echo sounder, absolute lag, and the like, from the inside of the vessel on the bottom 10 is installed around the clinket 8

ring-shaped element 6 with magnets 5 fixed on it (or electromagnets fixed in their place), oriented opposite poles relative to magnets 3. By means of underlining safety ropes (not shown in the drawing) fixed to ears 4, a cap 1 with permanent magnets fixed to it is brought 3 and the mountainous elastic element 11 with porous rubber 12 to the area of the clinket 8.

Using a diver, a plug 1 is installed under the collet 8 and fixed with permanent magnets 3, placing the latter under the corresponding additional magnets 5 (or electromagnets). Magnetic forces created by magnets 3 and 5 (or electromagnets) ensure reliable fixation of the plug 1 on the bottom of the vessel 10 made of non-ferromagnetic material, which is confirmed by physical modeling.

According to the diver’s signal, the clinket 8 is depressurized from the side of the vessel’s compartment. At the same time, the hydrostatic pressure acting on the plug 1 and chamber 11 presses the latter to the bottom of the vessel, thereby sealing the clinket 8 and thereby eliminating the flow of sea water into the vessel’s compartment.

Replace the antenna 9 and seal the clinket 8 from the side of the compartment of the vessel.

After that, remove the ring-shaped element 6 with permanent magnets 5 or electromagnets installed in their place, having previously de-energized the latter, then with the help of liner safety cables (not shown in the drawing) fixed to the ears 4, they will lift the cap 1 with the camera 11 and magnets on board the vessel 3.

The above analogues, including the prototype, also apply to the second embodiment of the inventive sealing device

The technical result, which the second version of the sealing device is aimed at, consists in securing the plug with its sealing means on the bottom of the vessel, made of non-ferromagnetic materials.

To achieve the technical result, a sealing device containing a plug, a means of sealing it and means of fixation attached to the plug is provided with electromagnets installed from inside the vessel, under which are placed plug fixation devices made of ferromagnetic material, for example, iron, nickel,

cobalt or their alloys. The latter, being in the magnetic fields created by the electromagnets, are attracted to them and thereby fix the plug with the means of sealing it on the bottom of the vessel, which is not made of ferromagnetic materials, which ensures the achievement of the above technical result.

Electromagnets, as in the first embodiment of the device in the drawings, are indicated by 5, and the means of fixing the plug made of ferromagnetic material correspond to 3.

The operating procedure of the second embodiment of the sealing device does not differ from the above operating procedure of the first embodiment of the device.
