Description

Technical Field

[0001] This invention relates to the field of oil pollution treatment equipment technology, and in particular to a marine oil pollution collection device. Background Technology

[0002] Accidents frequently occur during oil transportation and extraction, leading to crude oil spills on water surfaces. Oil spills at sea, in rivers, and lakes often cause more severe pollution due to the difficulty in collection, making them hard to resolve quickly.

[0003] At the same time, after an oil spill occurs at sea, measures should be taken to reduce its pollution and damage to marine resources and the environment. Whether in open waters or nearshore waters, the better way to deal with oil spills is to use specialized equipment for containment and recovery. Traditionally, when dealing with marine oil spills, tugboats are used to tow oil booms (3) to contain and intercept the spill, preventing it from spreading further and concentrating it to make it thicker for recovery. Then, oil spill recovery vessels, oil skimmers, and other equipment are used to recover the marine oil spill and transfer the recovered oil spill to temporary marine storage devices such as oil storage tanks. However, under the influence of wind, current, surge, and waves, the oil spill will quickly drift and spread outward from the leak point, forming a large area of ​​dispersed marine oil film and oil slick. It is under the influence of these factors that irregular leak areas with multiple ranges are formed, making it difficult to clean them up in a concentrated manner, thus requiring a large amount of manpower and resources. Moreover, setting up recovery oil booms takes a lot of time, further increasing the difficulty of oil spill treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a marine oil spill collection device for quickly and efficiently cleaning up oil spills in different areas of the sea surface. It is highly automated and saves labor costs.

[0005] To achieve the above objectives, the present invention provides a marine oil spill collection device, comprising: a recovery body, a floating mechanism, and an oil boom mechanism; wherein... The recovery unit internally comprises a drainage chamber, an oil-water mixing chamber, a first-stage oil storage chamber, an oil boom storage chamber, an air pump chamber, and a second-stage oil storage chamber. The drainage chamber and the first-stage oil storage chamber are located on opposite sides of the oil-water mixing chamber, separated by a hydrophilic-oleophobic membrane layer. The first-stage oil storage chamber is also separated from the oil-water mixing chamber by an oleophilic-hydrophobic membrane layer. The oil boom storage chamber is located between the first-stage and second-stage oil storage chambers, which are connected by a pipeline. The air pump chamber is arranged parallel to the oil boom storage chamber. The drainage chamber contains a drainage component for draining water outwards. The air pump chamber contains an air pump. The top of one side wall of the recycling body is provided with a water inlet that communicates with the interior of the oil-water mixing chamber; The floating mechanism includes a connecting frame and floating components installed at both ends of the connecting frame. The middle part of the connecting frame is fixedly connected to the recovery body. The floating components are connected to the air pump through an air inflation pipe. The oil boom mechanism includes an oil boom and a recovery component for recovering the oil boom into an oil boom storage chamber. One end of the oil boom is fixedly connected to the outer wall of the recovery body, and the other end is connected to the recovery component.

[0006] Furthermore, the drainage assembly includes a drainage pump and a drainage pipe, with one end of the drainage pipe connected to the drainage pump and the other end connected to the outside.

[0007] Furthermore, a guide plate is inclinedly arranged between the water inlet and the oil-water mixing chamber, and the guide plate is sealed to the top of the hydrophilic and oleophobic film layer.

[0008] Furthermore, the floating component is an airbag, and the floating component is fixedly installed on the connecting frame by a hoop.

[0009] Furthermore, the oil boom includes an upper chain, a lower chain, a floating body, and a skirt, wherein the floating body and the skirt are connected between the upper chain and the lower chain; The upper and lower chains are evenly spaced with slots; The skirt has connecting holes on both sides, and two adjacent skirt pieces are connected through the connecting holes.

[0010] Furthermore, the recycling assembly includes a mounting frame, two drive rollers arranged vertically opposite each other on the mounting frame, a gearbox connected to the drive rollers, and a motor; The motor drives the transmission roller to rotate axially via a gearbox; Gears are provided at both ends of the drive roller, and the oil containment barrier is arranged horizontally between the two drive rollers. The gear teeth are connected to the slots on both sides of the oil containment barrier. The recovery body has a recovery port at the top of the oil boom storage chamber, and one end of the oil boom passes through the recovery port into the oil boom storage chamber.

[0011] Furthermore, the oil boom storage chamber is provided with a diagonal brace plate, with the end of the diagonal brace plate near the recovery port being higher than the end away from the recovery port and inclined. An elastic support column is provided between the diagonal brace plate and the bottom of the oil boom storage chamber. The bottom of the elastic support column is fixedly connected to the bottom of the oil boom storage chamber, and the top of the elastic support column is rotatably connected to the bottom of the diagonal brace plate.

[0012] Furthermore, the oil boom and the recovery body are also connected by an oil-blocking cable. One end of the oil-blocking cable is provided with a slotted connector, and the outer side of the upper locking chain is provided with a slot extending along the axial direction. The slotted connector is slidably engaged with the slot.

[0013] Furthermore, the end of the oil boom is ball-jointed to the slot connector.

[0014] Furthermore, the other end of the oil boom is rotatably connected to the recovery body via a connecting rod.

[0015] The beneficial effects of this invention are reflected in: (1) By integrating oil collection and oil boom collection into one unit, the area range is continuously reduced by recycling the oil boom. The device is located within the area range. The main device is equipped with a water inlet. By shrinking the oil boom and continuously adjusting the height of the water inlet, the oil film is recovered in high density and then further separated and stored.

[0016] (2) Modify the structure of the oil boom by adding upper and lower chains and slots in them. The oil boom can be recycled through the upper and lower chains. Compared with traditional recycling, there is no need to stretch the oil boom, which will not damage the oil boom and makes the recycling more stable.

[0017] (3) When recovering the oil boom, it is necessary to lift it. In order to prevent oil spills and the impact of the floating of the oil boom under wind and waves on the recovery, an oil boom cable is provided. The oil boom cable is connected to the recovery body and the oil boom. The oil boom cable is connected to the slot on the oil boom to prevent oil spills and prevent the oil boom from getting tangled. (4) Multiple oil spill collection devices can be carried by a mother ship to operate in different spill areas and deployed along the coast. The oil spill collection devices can realize automated recovery of oil spills and oil booms on the sea surface. When the mother ship has completed the deployment in the last sea area, it can return to the first sea area to recover the oil spill collection devices released, saving a lot of manpower and resources.

Detailed Implementation

[0019] The specific embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0020] like Figures 1-12As shown in the figure, an embodiment of the present invention provides a marine oil spill collection device, comprising: a recovery body 1, a floating mechanism, and an oil boom mechanism. The recovery body 1 internally comprises a drainage chamber 10, an oil-water mixing chamber 11, a first-stage oil storage chamber 12, an oil boom storage chamber 13, an air pump chamber 14, and a second-stage oil storage chamber 15. The drainage chamber 10 and the first-stage oil storage chamber 12 are respectively located on opposite sides of the oil-water mixing chamber 11, separated by a hydrophilic-oleophobic film layer 104. The first-stage oil storage chamber 12 is separated from the oil-water mixing chamber 11 by an oleophilic-hydrophobic film layer 110. The oil boom storage chamber 13 is located between the first-stage oil storage chamber 12 and the second-stage oil storage chamber 15, connected by a pipe 151 located at the top of both chambers. The air pump chamber 14 is arranged parallel to the oil boom storage chamber 13. The drainage chamber 10 is equipped with a drainage assembly for draining water outwards. The air pump chamber 14 is equipped with an air pump 141. A water inlet 100 communicating with the interior of the oil-water mixing chamber 11 is provided on the top of one side wall of the recovery body 1.

[0021] A guide plate 101 is inclinedly arranged between the water inlet 100 and the oil-water mixing chamber 11, and the guide plate 101 is sealed to the top of the hydrophilic and oleophobic film layer 104.

[0022] The drainage assembly includes a drainage pump 102 and a drainage pipe 103. One end of the drainage pipe 103 is connected to the drainage pump 102, and the other end is connected to the outside. The drainage pump 102 discharges the seawater collected in the drainage chamber 10 to the outside through the drainage pipe 103.

[0023] The recovery body 1 is designed in an inverted trapezoidal shape, which makes it easier to increase the buoyancy of the device, and the irregular shape inside the recovery body 1 is mostly used for liquid storage. The inlet 100 is arc-shaped, which also facilitates the collection of oil. The oil-water mixture can enter the oil-water mixing chamber 11 through the inlet 100 and the guide plate 101. An oil film detection device is provided at the inlet 100, which sends a feedback signal to the control module of the air pump 141. By adjusting the air volume of the air pump 141 to the floating mechanism, the inlet 100 is continuously adjusted to be located at the oil leakage point, so that the oil-water mixture flowing into the oil-water mixing chamber 11 is mostly oil.

[0024] After the oil-water mixture enters the oil-water mixing chamber 11, seawater passes through the hydrophilic-oleophobic film layer 104 into the drainage chamber 10, and oil passes through the oleophilic-hydrophobic film layer 110 into the first-stage oil storage chamber 12. When the oil in the first-stage oil storage chamber 12 reaches a certain amount, it is transferred through the pipeline 151 to the second-stage oil storage chamber 15, increasing the oil storage capacity.

[0025] The floating mechanism includes a connecting frame 21 and floating components 2 installed at both ends of the connecting frame 21. The middle part of the connecting frame 21 is fixedly connected to the recovery body 1. The floating components 2 are connected to the air pump 141 through an inflation pipe 22. The floating components 2 are air bladders and are fixedly installed on the connecting frame 21 by clamps. The buoyancy of the floating components 2 is controlled by the air pump 141 to adjust the position of the water inlet 100 of the recovery body 1, thus creating feedback.

[0026] The oil boom mechanism includes an oil boom 3 and a recovery component 31 for recovering the oil boom 3 into the oil boom storage chamber 13. One end of the oil boom 3 is fixedly connected to the fixed interface 16 on the outer wall of the recovery body 1, and the other end is connected to the recovery component 31.

[0027] Furthermore, the oil boom 3 includes an upper locking chain 301, a lower locking chain 302, a floating body 303, and a skirt 304, with the floating body 303 and skirt 304 connected between the upper locking chain 301 and the lower locking chain 302. The upper locking chain 301 and the lower locking chain 302 have evenly spaced slots 307, and the lower locking chain 302 is a counterweight chain. The skirt 304 has connecting holes 305 on both sides, and adjacent skirt sections 304 are connected by cables connected within the connecting holes 305. The floating body 303 is a compressible material with a density less than water.

[0028] Furthermore, the recycling assembly 31 includes a mounting frame 313, two drive rollers 312 arranged vertically opposite each other on the mounting frame 313, a gearbox 314 connected to the drive rollers 312, and a motor 315. The motor 315 drives the drive rollers 312 to rotate axially through the gearbox 314. Gears 311 are provided at both ends of the drive rollers 312, and the oil containment boom 3 is arranged transversely between the two drive rollers 312. The teeth of the gears 311 are connected to the slots 307 on both sides of the oil containment boom 3. A recycling port 32 is provided on the top of the oil containment boom storage chamber 13 on the recycling body 1, and one end of the oil containment boom 3 passes through the recycling port 32 into the oil containment boom storage chamber 13.

[0029] In the recovery assembly 31, two pairs of gears 311 are paired with slots 307 in the upper and lower chains 301 and 302 of the oil boom 3. The rotation of the gears 311 continuously recovers the oil boom 3, which then enters the recovery body 1 through the recovery port 32 for storage. The continuous recovery of the oil boom 3 reduces the oil containment area, causing the oil in the leaking area to continuously concentrate in the recovery body 1, and then be recovered into the recovery body 1 through the water inlet 100.

[0030] Furthermore, a diagonal bracing plate 131 is provided inside the oil boom storage chamber 13. The end of the diagonal bracing plate 131 near the recovery port 32 is inclined higher than the end away from the recovery port 32. An elastic support column 132 is provided between the diagonal bracing plate 131 and the bottom of the oil boom storage chamber 13. The bottom of the elastic support column 132 is fixedly connected to the bottom of the oil boom storage chamber 13, and the top of the elastic support column 132 is rotatably connected to the bottom of the diagonal bracing plate 131.

[0031] The oil boom 3 enters the oil boom storage chamber 13 through the recovery port 32. The inclined support plate 131 is set at an angle, and the oil boom 3 falls down to one end of the recovery body 1 along the inclined support plate 131. As the number of oil booms 3 increases, under the action of gravity, the elastic support column 132 under the inclined support plate 131 continuously contracts, so that the inclined support plate 131 flattens. Through the simple structure, the oil boom 3 can be evenly distributed throughout the oil boom storage chamber 13.

[0032] Furthermore, an oil boom 3 is connected to the recovery body 1 by an oil boom cable 4. One end of the oil boom cable 4 is equipped with a slotted connector 41, and the outer side of the upper locking chain 301 is provided with an axially extending slot 306. The slotted connector 41 is slidably engaged with the slot 306. The end of the oil boom cable 4 is ball-jointed to the slotted connector 41. The other end of the oil boom cable 4 is rotatably connected to the recovery body 1 via a connecting rod.

[0033] When the oil boom 3 is retrieved and raised, there may be oil film spilling out from its gaps and the oil boom 3 may overturn due to the impact of wind and waves. The oil boom 4 can prevent oil from spilling out and fix the oil boom 3.

[0034] like Figures 13-14 Explanation of the aforementioned layout scheme: Because oil spills at sea are not a continuous whole due to various factors such as wind, waves, or different leak sources, traditional large-scale containment and recovery methods would greatly increase manpower and material resources. Therefore, this device can be carried by ships to handle the oil spills separately and can be deployed in multiple leak areas.

[0035] In a leak area, the device is first deployed, and one end of the oil boom 3 is fixed to the device recovery body 1 to surround the leak area. Then, the other end is connected to the recovery module 31, and the oil boom 4 is connected to the oil boom 3. Then the device can start operating, and the oil is collected and the oil boom 3 is recovered by continuously contracting the oil boom 3.

[0036] After deploying equipment in one leak area, the mother ship 5 can move on to the next. By deploying along the leak lines, the mother ship 5 avoids large areas of empty oil, significantly increasing efficiency and reducing manpower and material resources. By carrying multiple oil spill collection devices on a single mother ship and deploying them along the coast, the system can automatically collect oil spills and containment booms from the sea surface. Once the mother ship has completed deployment in the last leak area, it can return to retrieve the oil spill collection devices deployed in the first area, saving substantial manpower and resources.

[0037] The above are merely preferred embodiments of the present invention and do not constitute any limitation on the present invention. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and content disclosed in the present invention without departing from the scope of the present invention shall be deemed to have remained within the scope of protection of the present invention.
