The marine floating material recovery device (10) includes at least one buoyancy body (120), and the oil recovery unit (100) can float on the sea surface by buoyancy provided by the buoyancy body (120). The floating storage unit (200) included in the marine floating material recovery device (10) includes a buoyancy unit that provides buoyancy, so that the storage unit (100) can float.

[0033] A marine floating material recovery device (10) according to an embodiment of the present invention may include a recovery unit (100), a buoyancy body (120), a floating storage device (200), and a fence unit (300).

[0034] The oil recovery unit (100) can perform oil recovery operation, including a dual screw.

[0035] The floating storage device (200) is connected to the oil recovery unit (100) and can receive and store recovered oil from the oil recovery unit (100).

[0036] The floating storage device (200) has a seawater discharge port at the bottom, and a hydrophilic nano filter is arranged in the seawater discharge port, so that seawater can be discharged to the outside through the seawater discharge port.

[0037] The floating storage tank (200) is provided with a marine float discharge port at the top for transferring recovered oil to the outside, and the recovered oil can be transferred to the outside by an external pumping operation while a hose is connected to the marine float discharge port. The marine float discharge port may be equipped with a cam lock device.

[0038] The fence section (300) can guide the spilled oil to the oil recovery section (100). The fence section (300) can include a first fence (310) and a second fence (320).

[0039] The first end of the first fence (310) may be attached to the oil recovery unit. The first end of the first fence (310) may be attached to a fixing member arranged around the first screw. The second end of the first fence (310) may be connected to the buoyancy body (120) of the oil recovery unit (100) or a ring formed in the oil recovery unit (100) via a wire.

[0042] Meanwhile, depending on the embodiment, the oil recovery unit (100) can remove a pair of screws and install a pair of disks. The marine floating material recovery device (10) can selectively use the screws and disks according to the oil recovery situation.

[0043] Figure 2 is a drawing for reference in explaining a recovery unit and a buoyancy body according to an embodiment of the present invention.

[0044] FIG. 3 is a drawing for reference in explaining the core components of the oil recovery unit according to an embodiment of the present invention.

[0045] FIG. 4 is a drawing for reference in explaining the interior of a recovery unit and a buoyancy body according to an embodiment of the present invention.

[0046] Figures 5 and 6 are drawings for reference in explaining a first buoyancy body according to an embodiment of the present invention.

[0047] Referring to the drawing, the marine floating material recovery device (10) may include an oil recovery unit (100), a buoyancy body (120), and a pipe (250).

[0048] The oil recovery unit (100) can recover marine floating matter. The recovered marine floating matter can be referred to as recovered oil. To this end, the oil recovery unit (100) is rotatably mounted on one side with a first screw (111) and rotatably mounted on the other side with a second screw (112) so as to collect the recovered oil into an internal temporary storage unit (113).

[0049] The oil recovery unit (100) may include a first screw (111), a second screw (112), a temporary storage unit (113), a first scraper (131), and a second scraper (132).

[0050] The second screw (112) can be arranged symmetrically with the first screw (111) and the temporary storage (113) in between.

[0051] The temporary storage (113) can store the recovered oil recovered by the first screw (111), the first scraper (131), the second screw (112), and the second scraper (132).

[0052] The temporary storage (113) may include a hole (h). The hole (h) may be connected to a pipe (250).

[0053] A screw may be placed in the hole (h) and the pipe (250). The screw may be placed so that a portion of the screw protrudes from the hole (h) into the interior of the temporary storage (113). The screw is rotated by power provided by the motor, and the recovered oil may be transferred from the temporary storage (113) to the floating storage according to the rotation of the screw.

[0054] The first scraper (131) can guide the marine floating material recovered by the first screw (111) to a temporary storage device (113).

[0055] The first scraper (131) may be positioned so that one end is in contact with the surface of the first screw (111) or is spaced apart from the surface of the first screw (111) by a small distance.

[0056] The first scraper (131) can separate the marine floating material recovered by the first screw (111) from the first screw (111) by the rotation of the first screw (111).

[0057] The first scraper (131) may be arranged to form an incline when viewed from the side. For example, the first scraper (131) may be arranged so that the side facing the first screw (111) is higher and the side facing the temporary storage (113) is lower. For example, the first scraper (131) may be arranged so that the side facing the first screw (111) is lower and the side facing the temporary storage (113) is higher.

[0058] The first scraper (131) may have a plate shape. The first scraper (131) may be arranged at an angle.

[0059] Guide walls may be formed on both sides of the first scraper (131).

[0060] Meanwhile, the first scraper (131) can be mounted to the main body via at least one elastic member (e.g., a spring). Through this, the first scraper (131) can adjust the contact strength with the first screw (111) in the up-down and left-right directions.

[0061] Meanwhile, the main body is a lower component of the oil recovery unit (100), and the lower part forms a temporary storage unit (113), and the upper part is equipped with a first screw (111), a second screw (112), a first scraper (131), a second scraper (132), and a buoyancy body (120), which can be described as a component that serves as the skeleton of the oil recovery unit (100).

[0062] The second scraper (132) can guide the marine floating material recovered by the second screw (112) to a temporary storage device (113).

[0063] The second scraper (132) may be positioned so that one end is in contact with the surface of the second screw (112) or is spaced apart from the surface of the second screw (112) by a small distance.

[0064] The second scraper (132) can separate the marine floating material recovered by the second screw (112) from the second screw (112) by the rotation of the second screw (112).

[0065] The second scraper (132) may be positioned to form an incline when viewed from the side. For example, the second scraper (132) may be positioned higher toward the second screw (112) and lower toward the temporary storage (113). For example, the second scraper (132) may be positioned lower toward the second screw (112) and higher toward the temporary storage (113).

[0066] The second scraper (132) may have a plate shape. The second scraper (132) may be arranged at an angle.

[0067] Guide walls may be formed on both sides of the second scraper (132).

[0068] Meanwhile, the second scraper (132) can be arranged symmetrically with the first scraper (131) with a temporary storage device (113) in between.

[0069] Meanwhile, the second scraper (132) can be mounted to the main body via at least one elastic member (e.g., a spring). Through this, the second scraper (132) can adjust the contact strength with the second screw (112) in the up-down and left-right directions.

[0070] The buoyancy body (120) can provide buoyancy to the oil recovery unit (100). The buoyancy body (120) can be mounted on the oil recovery unit (100). For example, the buoyancy body (120) can be mounted on the oil recovery unit (100) via a bracket.

[0071] The buoyancy body (120) may include a first buoyancy body (121) and a second buoyancy body (122).

[0072] The first buoyancy body (121) may be mounted on one side of the oil recovery unit (100), and the second buoyancy body (122) may be mounted on the other side of the oil recovery unit (100). For example, the first buoyancy body (121) may be mounted on the front end of the oil recovery unit (100), and the second buoyancy body (122) may be mounted on the rear end of the oil recovery unit (110).

[0073] The first buoyancy body (121) and the second buoyancy body (122) can be manufactured using the same mold.

[0074] In this case, the second buoyancy body (122) has the same shape as the first buoyancy body (121), but can be mounted on the other side of the oil recovery unit (100) by rotating 180 degrees based on an axis formed in the vertical direction compared to the first buoyancy body (121).

[0075] The buoyancy body (120) forms a space inside, so that power system components of the oil recovery unit can be placed.

[0076] The marine floating debris recovery device (10) may further include a motor (151), a battery (152), and a power transmission unit (153).

[0077] The motor (151) may include a first motor and a second motor.

[0078] The first motor can generate rotational power provided to the first screw (111).

[0079] The second motor can generate rotational power provided to the second screw (112).

[0080] The battery (152) may include a first battery and a second battery.

[0081] The first battery can power the first motor.

[0082] A second battery can power a second motor.

[0083] The power transmission unit (153) may include a first power transmission unit and a second power transmission unit.

[0084] The first power transmission unit can transmit the rotational power generated from the first motor to the first screw (111).

[0085] The second power transmission unit can transmit the rotational power generated from the second motor to the second screw (112).

[0086] The first motor, the first battery, and the first power transmission unit can be placed in the first space (S) formed inside the first buoyancy body (121).

[0087] The second motor, the second battery, and the second power transmission unit can be placed in a second space formed inside the second buoyancy body (122).

[0088] The first buoyancy body (121) may include a plurality of protrusions (121a) protruding toward the first space (S) on the inner surface.

[0089] The first buoyancy body (121) may include a lower portion forming a first space (S) with an opening formed at the upper portion, and an upper portion coupled to the lower portion to cover the opening.

[0090] The protrusion (121a) may be formed at a position corresponding to the joining point. The protrusion (121a) may protrude from a groove (121b) formed in the lower portion for joining with the upper portion for the first space (S).

[0091] Meanwhile, the first motor (151) and the first battery (152) are arranged between a plurality of protrusions (121a) protruding from the inner surface of the first buoyancy body (121) toward the first space (S), so that the posture can be fixed due to the plurality of protrusions (121a). Since the plurality of protrusions (121a) restrain the first motor (151) and the first battery (152), even when the capturing part (100) moves, the first motor (151) and the first battery (152) can stably provide rotational driving force to the first screw (111).

[0092] The lower part is equipped with a rubber (180) that protrudes upward along the border of the first space (S) on the upper surface, and the upper part can be joined to the lower part while the rubber (180) is accommodated inside.

[0093] The marine floating debris recovery device (10) may further include a plate (160). The plate (160) may be placed between the lower and upper parts when the lower and upper parts are joined to improve watertightness. The plate (160) may be formed of a rubber material.

[0094] Meanwhile, the second buoyancy body (122) has the same shape as the first buoyancy body (121), except that the direction in which it is mounted on the main body (110) is different from that of the first buoyancy body (121). The description of the second buoyancy body (122) can be applied to the description of the first buoyancy body (121) described above.

[0095] Meanwhile, in preparation for continuous operation of the marine floating material recovery device (10), the first battery and the second battery may be configured to be replaceable. After the upper part of the first buoyancy body (121) and the second buoyancy body (122) is removed, the first battery and the second battery may be replaced.

[0096] The pipe (250) is connected between the temporary storage (113) and the floating storage (200) to transport the recovered oil to the floating storage (200).

[0097] The pipe (250) may be disposed at least partially below the buoyancy body (120). For example, when the floating reservoir (200) is mounted on the second buoyancy body (122), the pipe (250) may be connected to the floating reservoir (220) below the second buoyancy body (122), and at least a portion of the pipe (250) may be disposed below the second buoyancy body (122).

[0098] The marine floating material recovery device (10) may further include a screw. The screw is arranged inside the pipe (250) and can transfer recovered oil by rotation from the temporary storage (113) to the floating storage (200).

[0099] FIG. 7a is a drawing for reference in explaining the oil recovery operation according to the rotation of the screw according to an embodiment of the present invention.

[0100] Referring to the drawing, the marine floating material recovery device (10) can recover marine floating material according to the first mode or the second mode.

[0101] The rotation direction of the first screw (111) and the second screw (112) can be determined according to either the first mode or the second mode, which are distinguished according to the type of oil being effluent.

[0102] Mode 1 can be described as a mode for recovering marine floating debris with a viscosity low enough to form a slick. Mode 2 can be described as a mode for recovering marine floating debris or microplastics with a high viscosity that have solidified.

[0103] In the first mode (710), the first screw (111) and the second screw (112) can rotate from the outside of the oil recovery unit (100) toward the inside of the oil recovery unit (100). In the first mode (710), low viscosity marine floating matter can be recovered.

[0104] The first screw (111) and the second screw (112) can recover at least one of bunker A, diesel, kerosene, lubricating oil, and floating chemicals while rotating from the outside of the oil recovery unit (100) toward the inside of the oil recovery unit (100) when the first mode is selected.

[0105] In the first mode, the first screw (111) and the second screw (112) can rotate more slowly than in the second mode.

[0106] In the first mode, when the first screw (111) and the second screw (112) rotate at a high speed, a starvation phenomenon may occur. The rapid rotation of the first screw (111) and the second screw (112) causes water flow, and accordingly, a water hole is formed around the first screw (111) and the second screw (112), which hinders the recovery of marine floating objects.

[0107] To prevent the starvation phenomenon, low-speed rotation of the first screw (111) and the second screw (112) is required in the first mode, and the RPM (Rotations Per Minute) of the first screw (111) and the second screw (112) in the first mode may be lower than the RPM of the first screw (111) and the second screw (112) in the second mode.

[0108] In the second mode (720), the first screw (111) and the second screw (112) can rotate from the inside of the oil recovery unit (100) toward the outside of the oil recovery unit (100). In the second mode (720), high viscosity marine floating matter can be recovered.

[0109] The first screw (111) and the second screw (112) can recover at least one of bunker C, LSFO (low sulfur fuel oil) and microplastics while rotating from the inside of the oil recovery unit (100) toward the outside of the oil recovery unit (100) when the second mode is selected.

[0110] In the second mode, the first screw (111) and the second screw (112) can rotate faster than in the first mode.

[0111] In the second mode, the surface material and structure of the first screw (111) and the second screw (112), the rotation speed of the first screw (111) and the second screw (112), the type of marine float, the viscosity of the marine float, the density difference between the marine float and water, and the surface tension of the marine float cause the marine float to rise above the water surface to a certain height or more while remaining attached to the first screw (111) and the second screw (112).

[0112] In order to raise the marine float from the water surface by the rotation of the first screw (111) and the second screw (112), rapid rotation of the first screw (111) and the second screw (112) is required, and the RPM of the first screw (111) and the second screw (112) in the second mode may be greater than the RPM of the first screw (111) and the second screw (112) in the first mode.

[0113] When the marine float is raised, the marine float can be separated from the first screw (111) and the second screw (112) by the first scraper (131) and the second scraper (132) and dropped into the temporary storage (113).

[0114] To more efficiently recover marine debris in the second mode, the oil recovery unit (100) may further include a first support (135) and a second support (730). The first support (135) and the second support (176) may be positioned spaced apart from the first screw (111) and the second screw (112), respectively. The first support (135) and the second support (136) may guide marine debris separated from the screw (111) by the scraper (131) to a temporary storage (113) by gravity.

[0115] The first support (135) and the second support (136) can be placed under the first scraper (131) and the second scraper (132), respectively.

[0116] The first support (135) and the second support (136) can be inclined so that, when viewed from the side, the side facing the first screw (111) and the second screw (112) is higher and the side facing the temporary storage (113) is lower.

[0117] The first support (135) and the second support (136) may include a bend. The first support (135) and the second support (136) may extend while forming an incline toward the temporary storage (113), and may extend in a direction perpendicular to the temporary storage (113) from the bend.

[0118] The first support (135) and the second support (136) have a plate shape and may include guide walls on the side.

[0119] FIG. 8 is a drawing for reference in explaining a first connecting portion and a second connecting portion according to an embodiment of the present invention.

[0120] The first end of the pipe (250) may be connected to the hole (h), and the second end may be connected to the first connection portion (190). The first connection portion (190) may be classified as a sub-component of the pipe (250).

[0121] When the first connecting portion (190) is connected to the second connecting portion (290), the pipe (191, 250) can be connected to the floating storage device (200) by being connected to the second pipe (291).

[0122] The first connecting portion (190) may have a joining groove (193) formed at least partially along the circumference of the hole (191) formed inside.

[0123] The joining groove (193) may include a lower groove (193a) having a semicircular groove surrounding the lower portion of the hole (192) and a pair of guide grooves (193b) extending parallel to each other in an upward direction from both sides of the lower groove (193a). Referring to Fig. 2, the groove formed below the reference line (RL) in the joining groove (193) may be described as the lower groove (193a), and the groove formed above the reference line (RL) may be described as the guide groove (193b).

[0124] The floating storage (200) may include a second connection portion (290). The second connection portion (290) may include a second pipe (291) extending forward from the floating storage (200). The second pipe (291) may be in communication with the interior of the floating storage (200). When the second connection portion (290) is coupled with the first connection portion (190), the second pipe (291) may be in communication with the temporary storage (131) by being in communication with the first pipe (191).

[0125] The second connecting portion (290) may be formed with an insert portion (291) that fits into the joining groove (190). A portion of the insert portion (291) may have a semicircular shape that surrounds the lower portion of the hole formed at the end of the second pipe (291) so as to fit into the lower groove (193a).

[0126] When the insertion part (291) is guided along the guide groove (193b) and inserted into the lower groove (193a), the second pipe (291) can be connected to the first pipe (191).

[0127] Meanwhile, the second connecting portion (290) may further include a handle (295). When the worker pulls the handle (295) upward while the marine floating material recovery device (10) is floating on the sea surface, the second connecting portion (290) can be separated from the first connecting portion (190). Afterwards, when the handle (292) of the new floating storage (200) is held and the insertion portion (291) is inserted into the coupling groove (193), the replacement of the floating storage (200) is completed.

[0128] The floating storage device (200) can be formed to be replaceable by coupling and decoupling the first connecting portion (190) and the second connecting portion (290) depending on the storage amount of the recovered oil.
