Description

Technical Field

[0001] The present invention relates to a ship for recovering pollution sources when marine pollution occurs, and in particular to a marine pollution source recovery ship for recovering pollution sources generated in the ocean by storing them in a storage space inside the ship. Background Art

[0002] Typically, when a marine accident results in a pollution source (such as an oil film), methods such as oil booms, skimmers, or emulsifier spraying are usually used to remove the pollution source.

[0003] That is to say, when a large amount of oil spill occurs on an oil tanker, the oil film must be recovered urgently, but when the sea conditions are bad and the waves are large, the existing equipment is difficult to use effectively.

[0004] Oil absorbent cloths and the like are used to remove pollution sources adsorbed on the ground, but since the oil absorbent cloths can only be used once, a large amount of oil absorbent cloths will be consumed.

[0005] On the other hand, although the oil can be removed by spraying oil removal chemicals on the seawater contaminated by the oil film or absorbing it with oil absorbent cloth, there is a risk of the seawater being contaminated by the chemicals when spraying chemicals to remove the oil. When using oil absorbent cloth to remove the oil, there is also the problem of disposing of the cloth that has absorbed the oil. Moreover, since the removal efficiency of the pollution source is less than 10%, it is impossible to remove the oil on a large scale, and there is a problem of polluting the nature through evaporation, dissolution, sedimentation, diffusion, etc.

[0006] In response to this, Korean Patent Grant No. 10-2044150 and Patent Publication No. 10-2021-0120200 disclose oil recovery devices. However, these existing technologies are only capable of capturing marine pollutants on a small scale and are not suitable for industrial control. Therefore, there is an urgent need for a vessel that can quickly and massively collect oil from the source of pollution leaking to the site.

[0007] Summary of the Invention

[0008] Technical problem to be solved by the invention

[0009] The problem to be solved by the present invention is to provide a marine pollution source recovery ship, which is used to capture marine pollution sources through oil booms when sailing in marine pollution areas and store them in internal pollution source storage space through sewage suction ports, so as to collect oil leaked to the site as much and as quickly as possible, and prevent pollutants from causing marine pollution through evaporation, dissolution, sedimentation, diffusion, etc.

[0010] Another problem to be solved by the present invention is to provide a marine pollution source recovery ship for effectively separating various floating objects that enter the internal storage space along with the pollutants during the process of the pollution source flowing into the internal storage space for storage, thereby improving the efficiency of clearing marine pollution sources.

[0011] Technical solutions to solve problems

[0012] The marine pollution source recovery ship of the present invention is characterized in that it includes: a hull having a ballast water tank for storing ballast water, and a sewage suction port formed on the front side for allowing sewage to flow in; oil booms formed at both ends of the front side of the hull and deployed to capture seawater containing pollution sources generated in the ocean; and a sewage storage tank formed inside the hull and separately from the ballast water tank, for storing seawater containing pollution sources captured by the oil boom when flowing in through the sewage suction port.

[0013] Furthermore, the oil boom is wound and stored on a reel rotated by a hydraulic drive unit formed at both ends of the front side of the hull.

[0014] Furthermore, the hull is a floating barge-type ship structure without an engine that is navigated by a tugboat or a towing vessel, and the oil boom is deployed by connecting to the tugboat or the towing vessel.

[0015] Furthermore, the oil boom is deployed from both ends of the front side of the hull by the tugboat or towing vessel, and the deployed ends of the oil boom tied to the tugboat or towing vessel are separated from the tugboat or towing vessel and then tied together to prevent polluted floating objects from flowing out of the prevention and control area. Furthermore, when the oil boom is wound and stored on the reel rotated by the hydraulic drive unit formed at both ends of the front side of the hull, the floating objects collected in the oil boom flow into the interior of the sewage storage tank through the sewage suction port of the hull.

[0016] Furthermore, the hull is a ship structure equipped with an engine for navigation, and the oil boom is connected to a drone device adjusted by an operator and deployed.

[0017] Furthermore, the oil boom is a fiber belt wound on the drum, made of polyethylene-coated fiber, and coated with vinyl coating on both sides to prevent absorption of water in the contaminated area.

[0018] Furthermore, in the fiber belt, a rubber buoyancy portion and a rubber load portion are formed crosswise with the center portion in the longitudinal direction as a reference. The rubber buoyancy portion is formed on the upper side and is filled with at least one buoyant rubber ball filled with air, and the rubber load portion is formed on the lower side and is filled with at least one weighted rubber ball filled with sand.

[0019] Furthermore, a fixing rod is fixed to the fiber tape formed by the repeated intersection of the rubber buoyancy portion and the rubber load-bearing portion, for preventing folding in the width direction when wound on the reel. The fixing rod separates the mounting areas of the rubber buoyancy portion and the rubber load-bearing portion while maintaining a predetermined spacing. As a result, when the fiber tape is unwound, a portion of the fiber tape can protrude above the water surface while standing obliquely on the sea surface. When wound on the reel, the fiber tape maintains a uniform thickness and is wound without deviation, thereby preventing wrinkles (folding).

[0020] Furthermore, the rubber buoyancy part, the rubber load-bearing part and the fixing rod are inserted between the upper and lower fiber belts, and their circumferences are sewn or heat-sealed to protrude from the surface of the fiber belt and fixed as a whole.

[0021] In addition, the drum is supported by a support rod, which is connected to the two ends of the front side of the hull through a bidirectional rotating hinge structure so that the oil boom can be folded upward when not in use and can be moved horizontally when the oil boom is deployed to adjust the deployment length and deployment angle of the oil boom.

[0022] Furthermore, multi-stage seawater inflow pipes are formed on both sides of the sewage storage tank. The seawater inflow pipes are opened and closed by valves to guide the inflow of seawater to adjust the internal water level of the sewage storage tank.

[0023] In addition, the sewage storage tank is formed with at least one drainage pipeline. When the pollution sources contained in the seawater flowing into the sewage storage tank through the sewage suction port float above the seawater, the water level of the seawater is adjusted by opening and closing the valve to discharge the seawater to the rear of the hull.

[0024] In addition, the drainage pipelines include: a straight-moving direction drainage outlet, which is arranged in the center and is used to set the direction for the hull to move in a straight line; a side direction drainage outlet, which is arranged on the left and right sides of the hull and is used to set the direction for the hull to rotate to the left or right direction; and a downward drainage outlet, which is arranged between the straight-moving direction drainage outlet and the side direction drainage outlet, and is provided with a pair of left and right outlets, which are inclined and have their outlets facing the bottom surface. When the sewage stored in the sewage storage tank is discharged, the tail of the hull rises and the front of the hull drops, thereby controlling the sewage suction port to be below the sea surface.

[0025] Furthermore, floating object oil filter nets are respectively provided at the straight-direction drainage outlet, the side-direction drainage outlet, and the downward drainage outlet.

[0026] Furthermore, the valve is a manual valve opened and closed by an operator, or an electric valve opened and closed according to a control signal from a control panel.

[0027] Furthermore, a floating object collector is provided at a predetermined interval near the sewage suction port. The floating object collector has a plurality of rakes and is used to suck in floating objects flowing in together with the pollution source to separate the floating objects from the pollution source.

[0028] Furthermore, an air tank for maintaining balance is formed in the hull.

[0029] Furthermore, one or more oil-proof nozzles are formed on the hull.

[0030] Furthermore, a connection port is formed in the sewage storage tank, which is connected to a connection pipe for forcibly transporting the stored pollution source or floating objects to the outside.

[0031] Furthermore, an oil vapor recovery device is provided on the upper side of the sewage storage tank of the hull.

[0032] Effects of the Invention

[0033] As described above, the present invention provides a vessel including a floating debris collector, which can be expected to achieve the following effects: marine pollution sources captured by oil booms while navigating a marine pollution area are stored in an internal pollution source storage space through a sewage intake, thereby collecting as much oil as possible and as quickly as possible from leaking to the site, preventing pollutants from causing marine pollution through evaporation, dissolution, sedimentation, diffusion, etc., and effectively separating various floating objects that enter the internal storage space along with the pollutants during the storage process, thereby improving the efficiency of removing marine pollution sources.

[0034] The effects of the present invention are not limited to the above-mentioned effects, and those skilled in the art will clearly understand other effects not mentioned based on the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Figure 7 The following are a top view, a front view and an overlapping side view showing the unfolded state of an oil boom made of fiber strips according to an embodiment of the present invention: Figure 8 A top view showing a state in which the oil boom is separated from the tugboat or towing vessel and connected to form a closed loop in an embodiment of the present invention.

[0046] refer to Figures 1 to 8 The marine pollution source recovery ship according to an embodiment of the present invention includes: a hull 10, an oil boom 30, a sewage storage tank 40 and a reel 20, and may also include: a floating object collector 60, an air tank 70 for maintaining balance, an oil prevention nozzle 80, and an oil vapor recovery device 90.

[0047] The ship 10 is a floating barge-type ship structure without an engine that is navigated by a tugboat or a towing vessel 100 , and may include a ballast water tank 11 for storing ballast water, and a sewage suction port 12 for sewage to flow into the front side.

[0048] That is, when the hull 10 is sailing while being towed by the tugboat or towing vessel 100, sewage (seawater + oil and / or floating objects) generated in the marine pollution area flows in through the sewage suction port 12, and the sewage flowing in can be stored in the sewage storage tank 40.

[0049] The reels 20 are formed at both ends of the front side of the hull 10 and are rotated by a hydraulic drive unit (not shown). The oil boom 30 can be wound and stored on the reels 20 or unwound.

[0050] The drum 20 is supported by a support rod 21 and rotated by a hydraulic drive unit (not shown). The support rod 21 can be connected to the front ends of the hull 10 through a bidirectional rotating hinge structure 22, so that the oil boom 30 can be folded upward when not in use, and can be moved horizontally when the oil boom 30 is deployed by the tugboat or towing vessel 100 to adjust the deployment length and deployment angle of the oil boom 30.

[0051] The oil boom 30 is a fiber belt wound on the drum 20, which captures sewage (seawater + oil and / or floating objects) generated in the ocean after being unfolded. The fiber belt can accommodate a rubber buoyancy part 31, a rubber load-bearing part 32 and a fixing rod 33.

[0052] That is, the oil boom 30 is a fiber belt wound on the drum 20 and made of polyethylene coated fiber, and is coated with vinyl coating on both sides to prevent the absorption of water in the contaminated area, such as Figures 7a to 7c As shown in the specific example, in the fiber belt, the rubber buoyancy portion 31 and the rubber load portion 32 are formed crosswise with the center portion in the longitudinal direction as a reference. The rubber buoyancy portion 31 filled with at least one buoyancy rubber ball 31a filled with air is formed on the upper side, and the rubber load portion 32 filled with at least one weighted rubber ball 32a filled with sand is formed on the lower side.

[0053] This is to ensure that when the oil boom 30 is wound on the drum 20, the rubber buoyancy portion 31 and the rubber load-bearing portion 32 do not overlap in the upper and lower intersection areas of the fiber belt, but are located in the gap, thereby maintaining a wound state with a stable thickness.

[0054] Furthermore, the fixing rod 33 is fixed to the fiber belt formed by the repeated intersection of the rubber buoyancy portion 31 and the rubber load portion 32 to prevent folding in the width direction when wound on the reel 20. The fixing rod 33 separates the installation areas of the rubber buoyancy portion 31 and the rubber load portion 32 while maintaining a predetermined distance.

[0055] The rubber buoyancy part 31 , the rubber load-bearing part 32 and the fixing rod 33 may be inserted between the upper and lower fiber belts, and their circumferences may be sewn or heat-sealed to protrude from the surface of the fiber belt and fixed as a whole.

[0056] On the other hand, the rubber buoyancy portion 31 is formed crosswise and repeatedly at the upper part of the fiber belt with the fixed rod 33 as the boundary, and the rubber load-bearing portion 32 is formed crosswise and repeatedly at the lower part of the fiber belt with the fixed rod 33 as the boundary, so that when the fiber belt is unfolded, a part of it can protrude above the water surface in a state of standing obliquely on the sea surface, and when wound on the reel 20, it maintains a uniform thickness and is wound without deviation.

[0057] The oil boom 30 is connected to the tugboat or towing vessel 100 and deployed, and the deployed end of the oil boom 30 tied to the tugboat or towing vessel 100 is separated from the tugboat or towing vessel 100. Figure 8 As shown, the oil boom 30 is tied to form a closed loop to prevent polluted floating objects from flowing out of the prevention and control area. Moreover, when the oil boom 30 is wound and stored on the reel 20 rotated by the hydraulic drive parts formed at both ends of the front side of the hull 10, the floating objects collected in the oil boom 30 flow into the interior of the sewage storage tank 40 through the sewage suction port 12 of the hull 10.

[0058] The sewage storage tank 40 is formed inside the hull 10 and is separated from the ballast water tank 11. It is used to store sewage (seawater + oil and / or floating objects) captured by the oil boom 30 when it flows in through the sewage suction port 12. Multi-stage seawater inflow pipes 43 are formed on both sides of the sewage storage tank 40. The seawater inflow pipes 43 are opened and closed by valves 43a to guide the inflow of seawater to adjust the internal water level of the sewage storage tank 40. At least one valve (not shown) is formed on the rear side of the sewage storage tank 40. When the pollution source contained in the seawater flowing in through the sewage suction port 12 floats above the seawater, the water level of the seawater is adjusted to discharge the seawater to the rear of the hull 10.

[0059] The valve may be a manual valve opened and closed by an operator, or an electric valve opened and closed according to a control signal from a control panel (not shown).

[0060] In this case, the valve may be provided on a drainage line having a straight-line drainage port 41 a , a side-line drainage port 41 b , and a downward drainage port 41 c formed at the rear of the hull 10 .

[0061] More specifically, the straight-moving direction drain outlet 41a is arranged at the rear center of the hull 10, for adjusting the water level of the seawater and setting the direction for the hull 10 to move in a straight line. The side direction drain outlet 41b is arranged on the left and right sides of the hull 10, for setting the direction for the hull 10 to rotate to the left or right direction. The downward discharge outlet 41c is arranged between the straight-moving direction drain outlet 41a and the side direction drain outlet 41b, and a pair of left and right outlets are provided, which are inclined and their outlets face the bottom surface. When the sewage stored in the sewage storage tank 40 is discharged, the tail of the hull 10 rises and the front of the hull 10 drops, thereby controlling the sewage suction port 12 to be located below the sea surface.

[0062] At this time, the straight-line drainage outlet 41a, the side drainage outlet 41b, and the downward drainage outlet 41c are respectively provided with a floating oil filter 41d.

[0063] On the other hand, the seawater filling of the ballast water tank 11 and the sewage storage tank 40 is functionally controlled.

[0064] First, when the hull 10 is anchored or heading to a work site, the ballast water tank 11 is kept in a maximum filling state to maintain operational stability, while the sewage storage tank 40 is kept in a sufficiently empty state.

[0065] Furthermore, when the hull 10 arrives at the prevention and control operation site, the seawater inflow pipe 43 on the side of the hull 10 is opened, and the hull 10 filled with seawater in the sewage storage tank 40 is slowly sunk below the sea surface.

[0066] When the hull 10 sinks, floating debris that pollutes the ocean flows into the sewage storage tank 40 through the sewage suction port 12 at the front end of the hull 10. When sailing to the prevention and control operation site, the ballast water tank 11, which is kept at the maximum filling state, discharges ballast water to keep the water level at 30%.

[0067] When an amount of seawater corresponding to the amount of floating debris flowing into the sewage storage tank 40 is discharged through the drainage ports 41a, 41b, and 41c provided at the rear of the hull 10, the accumulated amount of polluting floating debris in the sewage storage tank 40 increases and the density decreases, thereby increasing the buoyancy. At this time, the ballast water originally maintained at a level of 30% is replenished to control the stability of the hull 10.

[0068] More specifically, with respect to the ballast water stored in the ballast water tank 11, when the hull 10 is anchored or heading for an operation site, the seawater inside the sewage storage tank 40 is drained to keep the sewage intake 12 above the sea surface, while the ballast water tank 11 is kept as full as possible to maintain the stability of the hull 10. During prevention and control operations, in order to keep the sewage intake 12 below the sea surface, the sewage storage tank 40 is filled with seawater, and the ballast water tank 11 is only filled to about 30%. As the amount of pollution collected from the source increases, the buoyancy increases, and ballast water is gradually added to ensure continued safe navigation.

[0069] Furthermore, when collecting marine pollution sources, the lower end of the sewage suction port 12 is always maintained at approximately 20 cm below the sea surface, and moves horizontally in the opposite direction of the movement of the hull 10, that is, forward, backward, left, and right, to pump out the seawater stored in the sewage storage tank 40 through any one of the drainage ports 41a, 41b, and 41c provided at the stern of the vessel, thereby ensuring space for new sewage to flow in, and repeating this sewage inflow and corresponding seawater discharge.

[0070] In this way, after the pollution sources flow in through the sewage suction port 12 at the front, the pollution sources with smaller specific gravity accumulate at the upper part, and the seawater with larger specific gravity that sinks is continuously pumped out, thereby filling and collecting the pollution sources in the sewage storage tank 40 to the maximum extent.

[0071] The floating object collector 60 has a plurality of rakes 61 arranged in multiple layers at predetermined intervals near the sewage suction port 12 for sucking floating objects flowing in together with the seawater to separate the seawater from the floating objects.

[0072] The air tank 70 for maintaining balance is used to maintain the balance of the hull 10 even if the storage water level of the ballast water stored in the ballast water tank 11 or the water level of the sewage flowing into the sewage storage tank 40 is unbalanced.

[0073] One or more oil prevention nozzles 80 are formed on the hull 10 for spraying a treatment agent for preventing and controlling pollution sources in marine pollution areas.

[0074] The oil vapor recovery device 90 is disposed on the upper side of the sewage storage tank 40 of the hull 10 .

[0075] That is, the oil vapor recovery device 90 may be disposed on the top of the sewage storage tank 40 to prevent the oil stored in the sewage storage tank 40 from causing air pollution.

[0076] On the other hand, a connection port 42 is formed in the sewage storage tank 40 , and the connection port 42 can be connected to a connection pipe 300 for forcibly transporting a pollution source or floating objects to the outside as needed.

[0077] Thus, according to the marine pollution source recovery ship of the embodiment of the present invention, Figures 1 to 8 As shown, first, when seawater flows into the sewage storage tank 40, part of the seawater stored in the ballast water tank 11 is discharged to maintain about 30%, and the buoyancy of the ship is adjusted so that the height of the sewage suction port 12 is slightly lower than the sea surface.

[0078] Subsequently, when a marine pollution zone occurs due to an oil spill caused by a maritime accident, the hull 10 (a floating barge-type ship structure without an engine) is moved to the marine pollution zone by a plurality of tugboats or towing vessels 100 .

[0079] When the hull 10 reaches the pollution source removal site, the valve 43a of the seawater inflow pipe 43 provided on the side of the hull 10 is opened, so that the seawater flows into the interior of the hull 10 through the outer inflow channel.

[0080] At this time, except for the operation of opening and closing the valve 43a, a separate circulation pump is not used (unpowered), and when the seawater flowing into the interior with the help of the weight of the hull 10 is maintained at a water level sufficient to submerge the inflow pipe 43 at the bottom of the interior, the valve 43a set at the bottom inflow pipe 43 is closed to prevent the seawater flowing into the interior of the hull 10 from being discharged again, and when the water level reaches the position of the second-stage inflow pipe 43, the valve 43a of the second-stage inflow pipe 43 is closed again to control the water level up to the inflow pipe 43 at the top.

[0081] In other words, the valves 43a formed on both sides of the sewage storage tank 40 are opened, allowing seawater to flow into the sewage storage tank 40 through the multi-stage seawater inflow pipe 43. Depending on the amount of seawater flowing into the sewage storage tank 40, the water level of the sewage suction port 12 formed on the front side of the hull 10 can be determined to be lower than the sea surface.

[0082] Next, the oil boom 30 of a fiber belt structure wound around the drum 20 formed at the front side of the ship 10 is connected to a plurality of tugboats or towing vessels 100 to deploy the oil boom 30 so that the oil boom 30 surrounds the marine pollution area.

[0083] Furthermore, the oil boom 30 deployed from both ends of the front side of the hull 10 by the tugboat or towing vessel 100 is separated from the deployed end of the tugboat or towing vessel 100, as shown in FIG. Figure 8 The lashing is performed as shown to form a closed loop to prevent the loss of polluted floating streams outside the control area.

[0084] The oil boom 30 is a fiber belt structure, with a rubber buoyancy portion 31 filled with at least one buoyant rubber ball 31a filled with air formed on its upper side, and a rubber load-bearing portion 32 filled with at least one weighted rubber ball 32a filled with sand formed on its lower side. Therefore, when deployed, the oil boom 30 can stand at an angle on the sea surface with a portion protruding above the water surface.

[0085] Next, according to the propulsion direction of the hull 10, the valves of the straight-line drain outlet 41a, the side drain outlet 41b and the downward drain outlet 41c attached to the lower part of the sewage storage tank 40 are selectively opened to discharge the seawater.

[0086] Therefore, the sewage generated in the marine pollution area cannot be discharged outside the oil boom 30 through the sewage suction port 12, but can flow into the interior of the hull 10 through the sewage suction port 12 formed on the front side of the hull 10 and be stored in the sewage storage tank 40 formed inside the hull 10.

[0087] That is, when the oil boom 30 is wound and stored on the reel 20 rotated by the hydraulic drive unit formed at both ends of the front side of the hull 10, the floating objects collected in the oil boom 30 can flow into the interior of the sewage storage tank 40 through the sewage suction port 12 of the hull 10 and be stored.

[0088] In other words, when the deployed oil boom 30 is rolled up and pulled toward the sewage suction port 12 to recover the sewage or when the oil boom 30 on both sides is towed by a tugboat or a towing vessel 100 , seawater and oil can flow into the sewage storage tank 40 .

[0089] At this time, by selectively opening the valves attached to the straight-line drain outlet 41a, the side drain outlet 41b and the downward drain outlet 41c at the lower part of the sewage storage tank 40, only a large amount of heavier seawater is discharged from the sewage storage tank 40 to the outside, and the seawater level in the sewage storage tank 40 is lowered. Therefore, the sewage storage tank 40 can quickly capture and store as much oil film as possible, and the oil film is leaked to the on-site pollution source.

[0090] On the other hand, the sewage flowing in through the sewage suction port 12 includes seawater, oil, and / or floating objects. The rake 61 of the floating object collector 60 located near the sewage suction port 12 separates the floating objects from the oil, allowing only seawater and oil to flow into the sewage storage tank 40. As a result, in the sewage storage tank 40, the oil floats on the surface of the inflowing seawater.

[0091] On the other hand, according to another embodiment of the present invention, although not shown, the oil boom 30 formed on the front side of the hull 10 equipped with an engine for navigation can also be configured to be deployed by a drone device (not shown).

[0092] Industrial Applicability

[0093] Although the technical concept of the marine pollution source recovery ship of the present invention has been described above with reference to the accompanying drawings, this is only an example of the most preferred embodiment of the present invention and does not limit the present invention.

[0094] Furthermore, while the above embodiments illustrate a polluted marine environment, common sense suggests that the present invention can also be effectively applied to the collection and removal of pollution from rivers or freshwater lakes. Therefore, the term "ocean" as used in this invention should be interpreted as encompassing "polluted areas" such as rivers or other polluted waters.

[0095] The present invention is not limited to the specific embodiments described above, and a person skilled in the art can make various modifications without departing from the spirit of the invention as claimed in the claims, and such modifications are within the scope of the claims.
