Description

EMERGENCY RESTORATION DEVICE FOR PUNCTURES

The present invention relates to a breakage blocker for emergency restoration of a hull breakage caused by a maritime accident such as ship stranding and collision.

In general, when a breakage occurs in the hull of an oil tanker due to a maritime accident such as a ship stranding or collision, it is necessary to quickly and emergency repair the breakage. If the breakage of the tanker hull is not quickly sealed, crude oil from the tanker may leak through the breakout, leading to secondary marine pollution accidents. Crude oil can cause serious marine pollution because it takes a significant amount of time to decompose.

The existing hole blocking method blocked the hole by driving a wooden wedge directly into the hole generated in the hull. However, if the shape of the pore was distorted and protruded or irregular, it was impossible to block it with a wooden wedge.

On the other hand, the present invention intends to propose a mechanism capable of rapidly recovering the breakage regardless of the type of breakage generated in the hull.

The operation unit 21 is connected to the screw rod 30 and the gear meshing structure. The operation unit 21 includes a case 213 , a first gear 211 provided inside the case 213 , a gear rod 214 connected to the first gear 211 inside the case 213 , and a first gear ( It engages with the 211 and includes a second gear 212 screwed to the screw rod 30 .

The operation part 21 is located above the sealing part 22 , and the bottom surface thereof is connected to the upper surface 221a of the sealing part 22 .

A lower portion of the gear rod 214 is connected to the center of the first gear 211 . The upper portion of the gear rod 214 penetrates through the case 213 and is exposed to the outside of the case 213 . The first gear 211 rotates by the rotation operation of the gear rod 214 .

The rotational force of the first gear 211 is transmitted to the meshed second gear 212 . The second gear 212 has a central portion screwed with the screw rod 30 to move along the screw portion 31 of the screw rod 30 .

As an example, the first gear 211 and the second gear 212 may be supported by support elements such as bearings to smoothly rotate inside the case 213 .

The screw rod 30 is provided with a screw part 31 on the outside. As an example, the screw rod 30 may be screw-coupled to the first female screw 121, the second female screw 122, and the second gear 212 .

The screw rod 30 controls the operation of the scissor operating unit 12 and the stop bar 11 by rotational operation to attach the pore blocker to the car portion, and the operating unit 21 of the blocking device 20 is the second By controlling the operation of the sealing part 22 by the rotational operation of the handle 214a, the sealing of the hole 1 is made.

On the other hand, the first handle 32 is provided on the upper portion of the screw rod 30 , and the second handle 214a is provided on the upper portion of the gear rod 214 . The screw rod 30 can be easily rotated through the first handle 32 . When the second handle 214a is rotated by hand, the rotational force of the second handle 214a is transmitted to the gear rod 214 to easily rotate the gear rod 214 .

The center of the second handle 214a is formed in the shape of a hexagonal head so that, if necessary, an electric wrench can be coupled. The rotational force of the gear rod 214 is transmitted to the second gear 212 via the first gear 211 .

The following describes the blockade process of the blockade of the dispatch blocker according to the present invention.

As shown in FIGS. 1 to 4 , the scissor operating unit 12 including the scissor anchor 124 is inserted into the hole 1 of the hull. At this time, the magnet 111 of the stop bar 11 is attached to the outer wall surface (1b) around the hole (1). The stop bar 11 can be easily fixed to the outer wall surface 1b through the magnet 111 .

In this state, the screw rod 30 is rotated by operating the first handle 32 . As the screw rod 30 rotates, the first scissor female screw 121 screwed to the screw rod 30 moves in the direction of the second female scissor screw 122 .

As the gap between the first female screw 121 and the second female screw 122 is narrowed, the other end of both sides of the scissor link 123 connected by the hinge shaft 125 spreads outward.

As the other end of the scissor link 123 spreads outward, the scissor anchors 124 on both sides assembled so as to be covered on the scissor link 123 spread in the direction of the inner wall surface 1a around the hole 1, and the hole ( 1) It is closely adhered to the inner wall surface (1a) of the periphery.

As the scissor anchor 124 is in close contact with the inner wall surface 1a around the hole 1, the stop bar 11 located on the opposite side with the wall of the hull in between naturally causes the outer wall surface 1b around the hole 1 The pore blocker is fixed to the pore as it closely adheres to the pore.

Gong blocker according to the present invention can maintain a fixed state in the area around the hole 1 of the hull by the scissor anchor 124 and the stop bar 11.

In this way, the scissor anchor 124 is closely adhered to the inner wall surface 1a around the hole 1, and the stop bar 11 supports the outer wall surface 1b around the hole 1, so that the hole blocker is attached to the hole. is firmly attached.

Manually rotating the second handle (214a) in a state in which the break blocker is fixed, or by biting an electric impact (wrench) on the upper gear rod 214 to rotate the gear rod 214 by the electric impact.

As the gear rod 214 rotates, the first gear 211 inside the case 213 connected to the gear rod 214 rotates. Since the first gear 211 is meshed with the second gear 212 , the rotational force of the first gear 211 is transmitted to the second gear 212 .

The second gear 212 moves in the direction of the hole 1 along the screw portion 31 of the screw rod 30 while rotating. By the operation of the second gear 212, the entire operation unit 21 is moved, so that the sealing portion 22 located under the operation unit 21 is in the area of the outer wall surface 1b around the hole 1 is pressed into In this state, the stop bar 11 is positioned inside the sealing part 22 .

At this time, the elastic pad 223 provided along the bottom edge of the sealing part 22 is composed of an elastic material such as rubber, urethane, etc. It is closely attached to 1b) and can completely block the hole (1).

In addition, since the elastic pad 223 is composed of a plurality of pads 223a, one pad 223a of the plurality of pads 223a is in close contact with the recessed portion of the outer wall surface 1b, and the other pad 223a is in close contact with the recessed portion of the outer wall surface 1b. ) can maximize sealing of the hole 1 because each pad 223a is independently in close contact with the outer wall surface 1b, such as in close contact with the protruding portion of the outer wall surface 1b.

Furthermore, since the tube 222 supports each pad 223a at the top, each pad 223a can be more closely attached to the outer wall surface 1b of the area around the hole 1 .

As can be seen, the present invention can completely block the pore regardless of the shape of the pore by enclosing the area around the pore wider than the pore and sealing the pore. In addition, the present invention can completely perform emergency recovery of a hole by sealing the hole in which the fracture surface protrudes by the allowable height inside the sealing part. In addition, since the present invention is a method of attaching a magnet provided on the bottom surface of the stop bar to the outer wall surface of the hole portion, the hole blocking operation can be easily performed.
