Description

The invention relates to a means of temporarily sealing bullet holes in liquid-filled rigid hollow products, in particular tanks, automobile and railway tanks filled with oil products, and can be used for temporarily sealing holes in ship hulls.

In the practice of operating tanks, automobile and railway tanks, there are cases of receiving bullet holes from small arms. The diameter of the bullet hole can be from 6 to 25 mm. As a rule, the edges of the holes are directed inside the container and have torn edges.

The most dangerous is filling holes in containers filled with oil products, as not only fuel losses and environmental pollution are possible, but also oil products may get on the face and body of the person eliminating the hole, and fires and explosions with human casualties are possible.

Known devices for temporary sealing of holes and cracks in liquid-filled steel tanks (RU P. No. 2423283 C1, IPC B63B 43/16, V65D 88/02, 05/24/2010; RU P No. 2414377 C1, IPC B63B 43/16, March 4, 2010). It is also known device B.C. for sealing holes with torn edges in the vessel wall (USSR. Copyright certificate No. 963895, class B63C 7/00, 03/27/1981).

The disadvantage of these devices is that the closing of the hole is carried out by a person who is in the immediate vicinity of the hole from which oil is poured and which can be harmful to the health of persons who close the holes.

A device for sealing holes (AS USSR No. 1345528, class B63B, 09/21/1984, neck removed 04/20/2000 BI No. 11).

The device comprises a conical deformable plug with a through axial channel for accommodating a threaded element with a head therein, a support with a groove for accommodating a seal, a plug clamping device made in the form of a plug connected to a tube through which a hollow spring-loaded rod having a shaped head is passed .

The disadvantages of this device are the design complexity and violation of safety precautions, which is expressed in the inevitable contact of oil products on the body and eyes of a person who closes a hole.

A device for repairing hollow cylindrical products is also known, consisting of a tube with holes and a movable sleeve with spokes located on it for opening the shell. The shell consists of two spherical parts, one of which is made of hard material, and the other is of elastic material and is attached to an elastic frame pivotally connected to the other ends of the spokes of the movable sleeve.

In this device, the elastic spherical part is installed inside the cylindrical product and performs the function of forming a cavity for filling with a sealing medium (AS USSR No. 1225980, class 16 L 55/18, 1984).

The disadvantage of this device is a violation of safety when sealing holes.

The closest in technical essence to the present invention and taken as a prototype is a device for temporarily sealing holes in the side of the vessel, containing an elastic cone plug and a torsion key. The elastic cork is made of rigid material and is equipped with an elastic tape of trapezoidal section, attached to the screw forming the outside of the cork (USSR copyright certificate No. 779169, class B63B 43/16, 01/08/1979).

The disadvantages of this device are:

- does not provide complete tightness between the elastic tape with a trapezoidal thread and the end face of the hole;

- is not excluded, despite the use of a torsion key, pouring oil on a person closing a hole.

The technical result of the invention is to improve safety during the elimination of a leak of an oil product and to increase the reliability of sealing a bullet hole in a tank with an oil product.

This technical result is achieved by the fact that in the device for temporarily sealing bullet holes in liquid-filled rigid hollow articles containing an elastic conical tube and a device for installing the tube in the hole, made in the form of a rod, one end of which is made with a socket wrench, and the other with with the flywheel for rotating the rod, according to the invention, two additional spring-separated bushings are placed on the rod, the closest to the plug of which is fixed to the rod rigidly, and the other from the side of the flywheel filled with an annular flanging and with the possibility of sliding along the rod, in which an annular groove is made, which is blocked by the spring in the idle position, and the device further comprises a conical screen mounted on the rod, facing the inner cavity towards the cork and made with spokes articulated between them, on which an elastic oil and petrol resistant transparent material is fixed, while the spokes of the conical screen with free ends are pivotally fixed to one on the fixed and the other on the movable a sleeve, behind the fastening point of one of which there is a coaxial annular groove of the rod through the hole at the moment of maximum compression of the spring for interaction with the clamp of the working position of the device, as well as the fact that the clamp of the working position of the device is made in the form of a carrier plate rigidly connected to the movable sleeve, in the center which fixed the axis of rotation of the spring-loaded lever interacting through the through hole in the sleeve with an annular groove of the rod.

In FIG. 1 shows a device for temporarily sealing bullet holes in liquid-filled rigid hollow articles (in section);

FIG. 2 - elastic conical plug with thread on the surface (in section).

A device for temporarily sealing bullet holes in liquid-filled rigid hollow articles includes an elastic stopper 1 with a holder 2 and a device (without position) for installing the stopper in the bullet hole.

The elastic plug 1 has a conical shape with a thread on the outer surface. The base of the elastic stopper is fixed to the holder 2 by means of a clamping ring 3, and the end face of the stopper 1 is glued to the holder 2 with oil and gas resistant glue. The clamping ring 3 is fixed on the holder with screws (without positions). An oil and petrol resistant rubber gasket 4 is glued onto the surface of the clamping ring 3. A shank 5 having a square cross-section is made on the opposite side of the holder 2.

The device for installing the plug in the bullet hole includes a hollow rod 6, one end of which is made with a socket wrench identical to the cross section of the shank 5, and a flywheel 7 is rigidly fixed on the other end to rotate the rod 6 and the stop 8 is mounted for rotation. On the hollow rod 6 there are additionally introduced two bushings 10 and 11 separated by a spring 9. The bush 10, located closer to the plug 1, is fixed to the rod 6 rigidly, and the sleeve 11 with an annular flange 12, located on the side of the flywheel 7, is slideable rod 6. On the rod 6 is made an annular groove 13, overlapped by a spring 9 in the idle position.

The device further comprises a conical screen (not positioned) mounted on the rod 6, facing the inner surface towards the plug 1.

The cone-shaped screen is made with pins 14 (short) and 15 (long) pivotally interconnected, on which an elastic oil and petrol-resistant transparent material 16 is fixed. The spokes 14 with their free ends are pivotally mounted on the fixed sleeve 10, and the needles 15 on the movable sleeve 11. Behind the point of fastening one of the spokes of the movable sleeve 11, a through hole (without position) is made, coaxial to the annular groove 14 of the rod 6 at the time of maximum compression of the spring 9.

On the rod 6 is rigidly fixed lock (without position) of the working position of the device. The latch consists of a carrier plate 17 rigidly fixed on the movable sleeve 11, in the center of which the axis of rotation 18 of the spring lever 19 is fixed, the end face 20 of which interacts through the through hole in the movable sleeve 11 with the annular groove 13 on the rod 6.

The device contains a set of plugs of various diameters at the base of the conical plug from 6 to 25 mm.

The termination of the bullet hole from which the oil flows out is as follows.

Visually evaluate the diameter of the hole. From the set of elastic plugs 1, a plug of the desired diameter is selected. The shank 5 of the elastic tube 1 is inserted into the end face of the hollow rod 6.

Behind the annular flange 12, the movable sleeve 11 is moved to the side of the tube until the end of the spring-loaded lever 19 enters the annular groove 13 on the rod 6.

In this case, the cone-shaped screen is opened and held in working position due to the interaction of the end face 20 of the spring-loaded lever 19 with the annular groove 13 on the rod 6. Using the rod 6, the conical tube is inserted into the hole, shoulder rests on the stop 8 on the rod 6, the tube is pressed against the hole and by rotating the flywheel 7, screw the plug into the hole until the oil product leak from the hole is completely stopped. Monitoring the process of sealing holes lead through a transparent conical screen.

Next, disconnect the device from the elastic tube. By pressing the spring-loaded lever 19, the conical screen is returned to its original idle position.

The invention improves safety during the liquidation of an oil product leak and improves the reliability of sealing bullet holes.
