Description

The invention relates to a means of temporarily sealing bullet holes in liquid-filled rigid hollow products, in particular in 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 can get on the face and body, 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 No. 2423283 C1, IPC V63B 43/16, B65D 88/02, 05/24/2010; RU No. 2414377 C1, MPK BV 43/16, 03/04/2010 g.). It is also known device B.C. for sealing holes with torn edges in the vessel wall (USSR Author's Certificate No. 963895, class B63C 7/00, 03/27/1981).

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

A device is known for sealing holes (AS USSR No. 1345528, class B63B 43/16, 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 F16D 55/18, 1984).

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

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

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 a device for temporarily sealing bullet holes in liquid-filled rigid hollow articles containing an elastic conical tube, a device for installing the tube in the hole, made in the form of a rod, on one end of which the tube is fixed with the possibility of replacement, and a handle, according to the invention, the rod is hollow, inside of which, with the possibility of longitudinal movement, there is a rod rigidly connected to a handle freely movable in the longitudinal slot of the rod, for on which it is limited by a specified distance between two annular protrusions of the rod, and the device additionally contains two compression springs, one of which is installed inside the rod at the end of the rod with the possibility of abutment on one of the annular protrusions of the rod, the other compression spring is installed on the rod between the additionally inserted bushings, the nearest to the cork of which is fixed on the rod rigidly, and the other on the side of the handle is made with an annular flanging and with the possibility of sliding along the rod, in which a through hole is made , blocked by a spring in the inoperative position of the device, a device for protecting against liquid splashing in the form of a cone-shaped screen mounted on the rod, which faces the inner cavity towards the cork and is made of an elastic oil and oil-resistant transparent material fixed to pivotally articulated spokes, one free ends of which are pivotally fixed on the fixed sleeve, and others on the movable sleeve, in which behind the fastening point of one of the spokes there is a through hole, coaxial with the through the rod at the moment of maximum compression of the spring to interact with the locking device working position, made in the form of a carrier plate rigidly connected to the movable sleeve of the carrier, in the center of which the axis of rotation of the spring-loaded s-shaped lever is fixed, the end face of one arm of which interacts with the through hole in the movable sleeve a through hole in the rod, while in the rod from the side of the movable sleeve in front of the second annular protrusion of the rod, a second, identical to the first, through hole and A rod retainer identical to the latch of the movable sleeve has been installed.

In FIG. 1 shows a device for temporarily sealing bullet holes in liquid-filled rigid hollow articles (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 tube 1 has a conical shape with annular protrusions on the outer surface, made in the form of a ruff. The base of the elastic tube is glued to the holder 2 with oil and gas resistant adhesive. From the side of the elastic stopper 1, an oil-and-petrol-resistant rubber gasket 3 is glued to the holder 2. A shank 4 is made on the opposite side of the holder 2 to interact with the installation of the stopper in the hole.

The device for installing the plug in the hole includes a hollow rod 5, one end of which in diameter corresponds to the diameter of the shank 4 of the plug 1 with the possibility of replacement, and a plug 6 is installed on the other end of the rod 5. A rod 7 with two ring protrusions 8 is placed inside the hollow rod 5 and 9, between which a handle 10 is rigidly fixed on the rod 7, which freely moves in the longitudinal slot 11 of the hollow rod 5. At the end of the rod 7 inside the rod 5, a compression spring 12 is mounted on the annular protrusion 8, the cat the second end rests against the plug 6. The length of the longitudinal slot 11 in the rod 5 should correspond to the difference in the length of the expanded and compressed spring 12, and the distance between the annular protrusions 8 and 9 on the rod 7 should be not less than the length of the longitudinal slot 11 in the rod 5. The annular protrusion 8 on the rod 7 is an abutment for the compression spring 12, and the protrusion 9 is an abutment for fixing the position of the rod 7 inside the rod 5.

The clamp position of the rod 7 inside the rod 5 in the compressed state of the spring 12 is made in the form of a carrier plate 13, in the center of which is fixed the axis of rotation 14 of the spring-loaded S-shaped lever 15. The end face of one shoulder (16) of the S-shaped lever 15 through the through hole 17 in the hollow the rod 5 interacts with the annular protrusion 9 of the rod 7. To ensure slipping of the end face of the S-shaped lever 15 through the annular protrusion 9 when the spring 12 is compressed, a bevel is made at the end of the lever 15 (without position).

On the inner surface of the hollow rod 5 closer to the plug 1, a guide ring 18 is rigidly fixed to ensure the movement of the rod 7 along the axial line.

The distance between the end face of the rod 7 and the end face of the shank 4 should be no more than the difference between the length of the expanded and compressed spring 12.

The device further comprises an oil splash protection device made in the form of a cone-shaped screen 19 facing the inner cavity toward the plug 1. The cone-shaped screen 19 is made of an elastic oil and petrol-resistant transparent material fixed to long spokes pivotally connected to each other, the free ends of which are pivotally mounted on an additionally introduced movable sleeve 21. The spokes 20 are pivotally connected to short spokes 22, the free ends of which are pivotally fixed to the additional relative to the fixed sleeve 23. Between the movable 21 and the fixed 23 bushings posted compression spring 24.

The movable sleeve 21 is made with an annular flanging 25. On the movable sleeve 21 behind the attachment point of one of the spokes a through hole 26 is made, coaxial with the through hole 27 on the rod 5 at the time of maximum compression of the spring 24.

The latch of the movable sleeve 21 is identical to the latch of the positions of the rod 7 and is made in the form of a carrier plate 28 rigidly connected to the movable sleeve of the rotation axis 29 of the spring-loaded S-shaped lever 30, the end face of one arm of which interacts with the through hole 26 in the movable sleeve 21 through hole 27 in the rod 5.

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 4 of the elastic tube 1 is inserted into the end of the hollow rod 5.

For annular flanging 25 move the movable sleeve 21 in the direction of the tube until the end of the spring lever 30 enters the through hole 27 in the rod 5.

In this case, the cone-shaped screen 19 is opened and held in working position due to the interaction of the end of the spring lever 30 with the through hole 27 on the rod 5. For the handle 10, the rod 7 is diverted to the side of the plug 6 until the spring 12 is fully compressed, while the end face 16 of the spring-loaded S-shaped the lever 15 interacts with the annular protrusion 9 of the rod 7, holding it in the working position. Using the rod 5, the conical plug is inserted into the hole. By pressing the spring-loaded lever 15, the annular protrusion 9 is released from engagement with the end face 16 of the S-shaped lever 15. The rod 7, under the action of the spring 12, moves toward the plug 1 and hits the end of the shank 4. The plug 1 enters the hole, being held in it by the ring protrusions . Hitting the shank 4 with the rod 7 is carried out until the oil leak from the hole is completely stopped. Observation of the process of closing the holes is carried out through a transparent conical screen that protects the eyes and face of the closing hole from the jet of oil.

Next, disconnect the device from the elastic tube. By pressing the spring-loaded lever 30, 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.
