Figure 1 shows the occurrence of a break in the hull. Seawater may not flow in when a break occurs at a high position from the sea level, but in general, when a break occurs in the hull, seawater flows from the outside of the hull to the inside. In some cases, the ship can be anchored in a port or on land to sufficiently repair the wave hole, but if the ship is far from the land or the situation is severe due to the size or location of the wave hole, prompt action is required. The ship's piercing waterproofing/oilproofing device and a waterproofing/oilproofing method using the same according to the present invention are proposed for the purpose of use when such quick measures are required. The hull puncture waterproofing/oilproofing device according to the present invention is a device for the crew onboard the ship to waterproof the inflow water from the punctures inside the hull or to prevent the outflow of oil or chemicals (CHEMICALS) out of the ship when a puncture occurs in the hull.

2 shows a waterproof/oilproof device according to an embodiment of the present invention. 3 shows that the waterproofing/oilproofing device according to an embodiment of the present invention waterproofs/oils the pores of the hull 10. 2 and 3, the waterproof/oilproof device according to an embodiment of the present invention includes a wing support surface 210 and an upper surface 220 provided at one end of the pillar 100 ( 200), a plurality of hinges 300 attached to the side surface of one end of the pillar 100 or the wing support surface 210, one end is coupled with the rotation axis of the hinge 300, and the head 200 of the hull 10 When it is inserted into a wave hole and exported to the outside of the hull 10, it is folded and unfolded from the outside of the hull 10 and caught in the wave hole, and the unfolded state occurs in the wing 400 and the hull 10 supported by the wing support surface 210. The seawater inflow prevention cylinder 500 and the wing 400, which cover all or part of the perforations, and have holes into which the columns 100 are inserted, are in contact with the outer surface 30 of the hull 10, and the seawater inflow prevention cylinder 500 It includes a fixing device inserted into the pillar 100 so as to contact the inner surface 20 of the hull 10.

Looking at each detailed configuration, the pillar 100 is a member of an elongated shape, the shape is not particularly limited. The cross section perpendicular to the longitudinal direction may be circular or polygonal. This is a part to be considered together with the fixing device, and a shape suitable for fixing the wing 400 and the seawater inflow prevention cylinder 500 to the hull surface in connection with the fixing device is sufficient. As a preferred example, the pillar 100 may be a rod having a thread formed in at least a portion of the section, and the fixing device may be characterized in that the nut 600 is coupled with the thread. In this case, the pillar 100 has a circular cross-sectional shape in the longitudinal direction, and a thread formed in a helix curve in the longitudinal direction of the pillar 100. The nut 600 serves to fix the wing 400 and the seawater inflow prevention cylinder 500 to the hull surface along the thread formed on the pillar 100.

The head 200 is provided at one end of the pillar 100 and includes a wing support surface 210 and an upper surface 220. Wing support surface 210 is a surface to which the hinge 300 can be attached, and even if the hinge 300 is attached or the hinge 300 is not attached, the wing 400 is supported when the wing 400 is unfolded. Play a role. In a preferred embodiment of the wing support surface 210, the wing support surface 210 may be a surface perpendicular to the longitudinal direction of the pillar 100. As a result, when the wing 400 is unfolded, the angle of the wing 400 and the column 100 is limited so that the angle formed by the wing 400 does not exceed 90 degrees, and the wing 400 is the outer surface of the hull 10 (30) It serves to support the reaction force against the pressing force.

In addition, the head 200 includes an upper surface 220, and the upper surface 220 is a configuration for distinguishing from the wing support surface 210 and refers to the head 200, not the wing support surface 210. The upper surface 220 may protrude, and the protruding upper surface 220 serves to guide the waterproof/oilproof device to be easily inserted when inserted into the pores. A preferred shape of the upper surface 220 may be a conical shape having a point.

The hinge 300 is a configuration that allows the wing 400 to rotate in combination with the wing 400. The hinge 300 may be attached to the wing support surface 210 that is a lower portion of the head 200 or may be attached to a side surface of one end of the pillar 100. Wherever the hinge 300 is attached, the position of the hinge 300 is fine if the wing 400 moving due to the hinge 300 can be supported by the wing support surface 210. In this specification, the wing support surface 210 and the side surface of one end of the pillar 100 are presented as a position to which the hinge 300 will be attached. One end of the pillar 100 means the same position as the one end of the pillar 100 on which the aforementioned head 200 is provided, and when the hinge 300 is attached to the side of the one end, the wing 400 is winged It is possible to receive support from (210).

Since the wing 400 is configured to catch a hole outside the hull 10, the total length of the spread wing 400 is preferably larger than the diameter of the hole. In addition, the waterproof/oil-proof device of the present invention is characterized in that it is inserted into the outside of the hull 10 through a hole inside the hull 10, so the wing 400 must be folded when inserted into the outside of the hull 10 to reduce the diameter. do. Therefore, it is preferable that one end of the wing 400 is coupled with the rotation shaft of the hinge 300 to be constricted and unfolded. The number of wings 400 is not limited, but it is preferable that the number of wings 400 be at least one or more due to the nature of the invention. The shape of the wing 400 is not particularly limited, and it is sufficient if it is suitable for intimate contact with the outer surface 30 of the hull 10 from the outside of the hull 10.

And the wing 400 is characterized in that it is folded when the head 200 is inserted into the perforations of the hull 10 to be released outside the hull 10 and then unfolded from the outside of the hull 10, so that one end of the head 200 It is coupled to the upper surface 220, the other end may further include an elastic body coupled to the wing 400. Thus, even if the wing 400 is folded when inserted into a wave hole, it returns to the unfolded state from the outside of the hull 10 again. In addition, the elastic body may be any one having a restoring force, but a preferred embodiment may be a spring 410.

In addition, as an embodiment, it may be performed to initially prevent seawater flowing into the hull by using a membrane cloth 420 made of cloth or vinyl and connecting the wings. When the wing is unfolded, the blocking stream 420 becomes an umbrella-like shape to effectively block the inflow of seawater in the initial stage.

The seawater inflow prevention cylinder 500 is configured to prevent the inflow of seawater by intimate contact with the outside of the pores when irregularities occur in the hull 10. The seawater inflow prevention cylinder 500 is sufficient as long as it has a shape that can cover the pores of the hull 10, but preferably the head 200 of the waterproof/oilproof device is inserted from the inside of the hull 10 to the outside of the hull 10 When inserted into the furnace, it may have a concave shape toward the perforation. Since the seawater inflow prevention cylinder 500 is configured to directly block the inflow of seawater by blocking the pores, it would be desirable to have a size capable of covering all the pores, but it is okay if not. Since the size of the pores is larger than the seawater inflow prevention cylinder 500, even if only part of the pores are covered with the seawater inflow prevention cylinder 500, it is meaningful because the inflow of seawater can be reduced.

As mentioned above, the wing 400 is in close contact with the outer surface 30 of the hull 10, and the seawater inflow prevention cylinder 500 is in close contact with the outer surface 30 of the hull 10 and the inner surface of the hull 10 20) serves to fix the seawater inflow prevention cylinder 500 in close contact. Therefore, any configuration capable of fixing the seawater inflow prevention cylinder 500 to the column 100 may be used. In a preferred embodiment, the pillar 100 and the fixing device are made of a bolt and nut 600 structure, and may be sturdy to withstand hydraulic pressure.

The pressure control valve 530 is a configuration for facilitating installation of the waterproofing/oilproofing device when the watertight/oilproofing device according to the present invention is installed on the hull surface, when the pressure of seawater flowing through the pores is high. When pressure is applied to the seawater inflow prevention cylinder 500 through the perforation, it is not easy to install it on the inner surface 20 of the hull 10, so that the seawater flowing into the seawater inflow prevention cylinder 500 can be discharged. It is for sake. The pressure control valve 530 is sufficient as long as it is capable of discharging seawater upon opening and closing, and the shape or type is not particularly limited. In a specific embodiment, the pressure control valve 530 may be opened to install a waterproofing/oilproofing device and then the pressure control valve 530 may be closed to complete the waterproofing/oiling.

In the case of oil leakage, if the hydraulic pressure in the cylinder is excessive, the oil in the seawater inflow prevention cylinder 500 by using a connection pipe hose to the pressure control valve 530 to prevent oil from leaking between the seawater inflow prevention cylinder 500 and the hull. It prevents marine pollution by loading it into a ship or container prepared at sea by flowing it.

Referring to the drawings, in the drawing, the main gasket 520 coupled to the seawater inflow prevention cylinder 500 is shown in Fig. 4 (a), and Fig. 4 (b) shows a cross section of the main gasket 520 As shown in Figure 4 (b), the main gasket 520 is composed of hard, heavy, and soft materials to cover the protruding portions of the pores to block the inflow of seawater.

Since the seawater inflow prevention cylinder 500 covers the pores inside the hull and prevents the inflow of seawater, it is important to closely contact the inner surface of the hull. The inner surface of the hull may be flat, but may be a curved surface or an irregular surface with repeated irregularities. It is preferable to attach a gasket to the seawater inflow prevention cylinder 500 in order to closely adhere to any type of inner surface. The main gasket 520 is preferably made of a material having elasticity or a material having a high elastic modulus. As an example, the material of the main gasket 520 may be an ethylene-vinyl acetate copolymer (EVA), an ethylene vinyl acetate copolymer, or a silicone gasket.

5 is a view showing that the nut gasket 610 and the washer 620 are coupled between the seawater inflow prevention cylinder 500 and the nut 600 according to an embodiment of the present invention. Referring to the drawings, the seawater inflow prevention cylinder 500, a nut gasket 610, a washer 620 and a nut 600 are shown. Even if the seawater inflow prevention cylinder 500 sufficiently covers the pores to seal the gap between the seawater inflow prevention cylinder 500 and the inner surface of the hull, the gap between the hole and nut 600 where the seawater inflow prevention cylinder 500 and the column are combined Seawater may also be introduced. Therefore, the gap between the seawater inflow prevention cylinder 500 and the pillar and the gap between the seawater inflow prevention cylinder 500 and the nut 600 are blocked, so that seawater does not leak from the nut 600, the seawater inflow prevention cylinder 500 and the A nut gasket 610 may be inserted between the nuts 600.

In addition, a washer 620 may be inserted between the seawater inflow prevention cylinder 500 and the nut 600 to stably receive force from the nut 600 and distribute the force properly, and the nut gasket 610 and the washer ( When 620 is inserted together, it is preferable to combine the seawater inflow prevention cylinder 500, the nut gasket 610, the washer 620 and the nut 600 in order.
