Description

Technical Field

[0001] This invention relates to the field of polluted seawater treatment and remediation technology, specifically to a marine ecological restoration device. Background Technology

[0002] Marine ecological restoration is an ecological process that combines human intervention with natural mechanisms. The marine ecosystem is the object of marine ecological restoration. Marine ecological restoration not only involves the reconstruction of biological community structure and the restoration and improvement of habitat, but also includes the restoration of ecological functions. Just like the human body, the marine ecosystem also has the ability to actively heal its wounds.

[0003] In the treatment of marine oil spills, the oil is typically contained by barriers, and then absorbent pads are dropped onto the sea surface to remove it. However, this method suffers from several drawbacks: the containment area is large, automatic oil removal is not possible, the absorbent pads cannot be reused, resulting in wasted resources, and the oil cannot be thoroughly and effectively cleaned. This leads to high labor intensity and poor oil purification results. To address these shortcomings of existing technology, we propose a marine ecological restoration device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a marine ecological restoration device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine ecological restoration device, comprising an installation base for mounting on a ship hull, a sludge collection hopper for collecting marine oil pollution, an oil pollution separation base, and a purification and filtration base.

The output end of the second drive motor has a mesh cylinder that passes through the isolation seat and rotates with it. The mesh cylinder is located inside the sealing hole. An isolation filter screen is wrapped around the mesh cylinder, and the isolation filter screen seals the sealing hole.

[0009] The purification filter seat is equipped with an exhaust assembly that discharges airflow into the purification filter seat. The exhaust assembly is located on the rear side of the isolation seat, and a drain pipe is located on the front side of the purification filter seat.

[0010] Furthermore, the lifting assembly includes a hydraulic push rod located at the upper end of the mounting base. The push rod of the hydraulic push rod is provided with a support frame that connects to the outside of the sludge collection hopper. The sludge collection hopper has an opening on the left side and is shaped like a shovel.

[0011] Furthermore, the connector includes a threaded head located at the right end of the floating purse and a threaded cylinder located on the right side of the fixed base that is threadedly adapted to the threaded head.

[0012] Furthermore, the winding assembly includes a U-shaped seat located on the right side of the support frame. A servo motor is provided on the right side surface of the U-shaped seat, and a winding roller that rotates with the inner wall of the U-shaped seat is provided at the output end of the servo motor. The floating cable is wound and fixed around the outside of the winding roller.

[0013] Furthermore, the oil sludge extraction assembly includes an oil sludge pump located outside the oil sludge separation seat. A flexible hose connects the oil sludge extraction port of the oil sludge pump to the straight pipe, and a rigid pipe connects the oil sludge discharge port of the oil sludge pump to the discharge head.

[0014] Furthermore, it also includes an oil sludge collection seat, and the outer side of the oil sludge separation seat is provided with a hollow tube communicating with the perforation. The lower end of the hollow tube is connected to a plurality of oil sludge separation drain pipes located above the oil sludge collection seat.

[0015] Furthermore, the oil-sludge separation seat has a pipe located below the diversion plate inside, and multiple spray heads facing the oil suction belt are connected to the outside of the pipe.

[0016] Furthermore, the exhaust assembly includes a hollow plate located at the bottom of the purification filter seat and on the rear side of the purification filter seat.

[0017] Furthermore, a sediment discharge pipe extends through the hollow plate to the bottom of the purification filter seat, and the other end of the sediment discharge pipe is connected to a sediment storage seat.

[0018] Furthermore, the drain pipe is externally connected to an automatic on / off valve.

[0019] Compared with existing technologies, the present invention provides a marine ecological restoration device with the following beneficial effects:

[0020] 1. This marine ecological restoration equipment is installed on the hull of a ship and carried to the oil spill area. The equipment is then lifted into the sea by a lifting assembly to move the collection hopper. At the same time, by opening the disassembly connector, one end of the floating seine cable is fixed to the unmanned remote-controlled vessel. The unmanned remote-controlled vessel is then driven to move the floating seine cable. The winding assembly simultaneously releases the floating seine cable, which can surround and contain the oil spill on the sea surface. After containment is completed, the floating seine cable is connected and fixed to the fixed base by the connector.

[0021] After the oil is contained, the floating choke is wound up by the winding assembly, which slowly collects the oil in the collection hopper. Then, the oil suction assembly works with the suction head on the straight pipe to suck out the oil from the collection hopper. This achieves automatic containment and cleaning of oil on the sea surface, greatly reducing the labor intensity of the operation.

[0022] 2. This marine ecological restoration equipment discharges oil sludge into the discharge trough on the diversion plate through the discharge head, diverting the sewage to the oil-absorbing belt on the rotating roller. The oil sludge in the sewage is absorbed, and the drive motor drives the oil-absorbing belt on the rotating roller to rotate. During the rotation, the scraper scrapes off the oil sludge on the oil-absorbing belt and discharges it along the slope of the scraper into the perforation. This achieves the cleaning and discharge of most of the oil sludge in the sewage, and at the same time realizes the circulation cleaning and sewage treatment.

[0023] In addition, the wastewater after oil separation is discharged into the purification filter through the sewage pipe. By adding flocculant into the purification filter and using the exhaust component to evenly discharge airflow to generate bubbles, the impurities and oil are attached to the bubbles and float to the surface. This improves the aggregation effect of the flocculant on oil and suspended solids in the water, forming larger flocs and improving the further cleaning effect on oil and impurities in the wastewater.

[0024] In addition to the isolation and sealing by the isolation seat, and the isolation of the flocs by the combination of the mesh cylinder and the isolation filter, the purified seawater is discharged to the other side of the isolation seat and discharged through the drain pipe. When the drive motor drives the mesh cylinder and the isolation filter to rotate, the isolation filter comes into contact with the isolation seat to clean the flocs on the surface of the isolation filter and prevent the drainage from getting blocked.

The diverter plate 19 is of equal length to the diverter plate 23 and has two... The upper surface of the diversion plate 19 is provided with a drain trough 20, which corresponds to the number of drain heads 17 and is located below the drain heads 17.

The rear side surface of the oil-stain separation seat 18 is provided with a plurality of perforations 25 evenly distributed above the scraper 24. The perforations 25 are used to discharge the separated oil.

[0040] The oil sludge extraction assembly includes an oil sludge pump 14 that is bolted to the front surface of the oil sludge separation seat 18. A flexible hose 15 is connected between the oil sludge extraction port of the oil sludge pump 14 and the straight pipe 5, and a rigid pipe 16 is connected between the oil sludge discharge port of the oil sludge pump 14 and the discharge head 17.

[0041] The lower surface of the oil-stain separation seat 18 is connected to a drain pipe 29. The other end of the drain pipe 29 is located above the purification filter seat 30. An isolation seat 31 is installed and fixed in the purification filter seat 30 in a left-right partition. The isolation seat 31 has a sealing hole through it in the front-back direction. A second drive motor 32 is fixed to the left side surface of the purification filter seat 30 by bolts. The output end of the second drive motor 32 is provided with a mesh cylinder 33 that passes through the isolation seat 31 and rotates with it. The mesh cylinder 33 has evenly distributed mesh holes on its outside. The mesh cylinder 33 is located inside the sealing hole. An isolation filter 34 is wrapped around the mesh cylinder 33 to cover the mesh holes. The isolation filter 34 seals the sealing hole.

[0042] This application also includes an oil collection seat 28, and a hollow tube 26 connected to a perforation 25 is fixed to the rear side of the oil separation seat 18. The lower end of the hollow tube 26 is connected to a plurality of oil separation drain pipes 27 located above the oil collection seat 28.

[0043] The oil-sludge separation seat 18 has a pipe 43 located below the diversion plate 19 inside. The pipe 43 is connected to a plurality of spray heads 44 that are evenly distributed and facing the oil suction belt 23. The surface of the oil-sludge separation seat 18 is provided with a liquid pump 45. The discharge port of the liquid pump 45 is connected to the pipe 43. The liquid pump 45 is connected to a liquid suction pipe 46 that extends into the purification filter seat 30 and is located in front of the isolation seat 31.

[0044] The length of the spray head 44 is equal to the length of the oil absorption belt 23, which makes it easy to coordinate with the rotation of the oil absorption belt 23. The spray head 44 sprays water to clean the surface of the oil absorption belt 23 in all directions.

[0045] The purification filter seat 30 is equipped with an exhaust assembly that discharges airflow into the purification filter seat 30. The exhaust assembly is located on the rear side of the isolation seat 31. The front side of the purification filter seat 30 is equipped with a drain pipe 41 located on the front side of the isolation seat 31.

[0046] The exhaust assembly includes a hollow plate 35 located at the bottom of the purification filter base 30 and on the rear side of the purification filter base 30. The upper surface of the hollow plate 35 is evenly connected with exhaust heads 36 distributed at equal intervals. A booster fan 37 is fixed on the right side of the purification filter base 30. An air pipe 38 is connected between the exhaust port of the booster fan 37 and the hollow plate 35.

[0047] A sediment discharge pipe 39 passes through the hollow plate 35 and extends to the bottom of the purification filter seat 30. The other end of the sediment discharge pipe 39 is connected to the sediment storage seat 40. An automatic switch valve 42 is connected to the outside of the drain pipe 41.

[0048] The upper end of the sedimentation storage base 40 is open, and a cover is provided at the opening. The sediment discharge pipe 39 is connected to the sedimentation storage base 40 through the cover. The flocs in the sediment discharge pipe 39 can be cleaned by opening the cover.

[0049] The structural design principle and usage steps are as follows: Install the mounting base 1, oil sludge separation base 18, oil sludge collection base 28, and sedimentation storage base 40 onto the hull using fastening screws, ensuring that all components are securely connected. Check the installation of power equipment such as hydraulic push rod 2, servo motor 12, oil sludge pump 14, drive motor one 21, drive motor two 32, and booster fan 37 to ensure they are secure. Connect the power supply and conduct a trial run to ensure that all components can work normally. Perform a sealing check on components such as oil sludge pump 14, hose 15, rigid pipe 16, straight pipe 5, suction head 6, and discharge head 17 to ensure that the oil sludge pumping system is leak-free. At the same time, check whether the connection between the floating lanyard 10 and the fixed base 7 is reliable and whether the winding assembly can properly wind and unwind the floating lanyard 10.

[0050] The mounting base 1, oil separation base 18, oil collection base 28, and sedimentation storage base 40 are installed on the hull with fastening screws. After the equipment is carried to the oily sea surface, the collection hopper 4 on the support frame 3 is moved and raised into the sea surface by the hydraulic push rod 2. At the same time, the threaded head 9 is separated from the threaded cylinder 8 by rotating the threaded head 9 and the threaded head 9 is threadedly fixed on the unmanned remote control boat. The unmanned remote control boat is driven to move the floating lanyard 10 on the sea surface. The servo motor 12 works to drive the winding roller 13 to rotate and loosen the wound floating lanyard 10. This allows the floating lanyard 10 to surround and trap the oil on the sea surface. After trapping, the floating lanyard 10 is connected to the fixed base 7 by rotating the threaded head 9 and threaded cylinder 8.

[0051] After the oil is contained, the servo motor 12 drives the winding roller 13 to rotate and wind up the floating sluice cable 10. The floating sluice cable 10 moves within another fixed seat 7, gradually reducing the encirclement of the floating sluice cable 10 and slowly accumulating the oil in the collection hopper 4. In conjunction with the oil pump 14, the oil pump 14, hose 15, straight pipe 5, suction head 6, rigid pipe 16 and discharge head 17 are interconnected, enabling the suction head 6 to suck out the oil in the collection hopper 4. This achieves automatic containment of oil on the sea surface and automatic cleaning of the contained oil, greatly reducing the labor intensity of the operation.

[0052] The pumped-in sewage discharges oil sludge into the drain trough 20 on the diversion plate 19 through the drain head 17, and the sewage is diverted to the oil suction belt 23 on the rotating roller 22 to ensure the absorption effect of the oil suction belt 23 on the sewage. With the help of the drive motor 21, the oil suction belt 23 on the rotating roller 22 is rotated. During the rotation, the scraper 24 scrapes off the oil sludge on the oil suction belt 23 and discharges it along the inclined surface of the scraper 24 into the perforation 25. The oil sludge is discharged into the hollow tube 26 through the perforation 25 and then into the oil collection seat 28 through the oil separation drain pipe 27 for storage. This achieves the cleaning and discharge of most of the oil sludge in the sewage, and at the same time realizes the circulation and cleaning treatment of the oil suction belt 23.

[0053] After the scraper 24 removes the oil stains from the outside of the oil absorption belt 23, the liquid pump 45 operates. By utilizing the interconnection between the liquid pump 45, the pipe 43, the spray head 44, and the liquid extraction pipe 46, the liquid extraction pipe 46 extracts the purified seawater from the purification filter seat 30 and sprays it out through the spray head 44 to wash and clean the residual oil stains on the surface of the oil absorption belt 23, ensuring the oil absorption belt 23's adsorption effect on oil stains.

[0054] In addition, the wastewater after oil separation is discharged into the purification filter seat 30 through the sewage pipe 29 connected to the oil separation seat 18. By adding flocculant into the purification filter seat 30 and cooperating with the operation of the booster fan 37 to discharge airflow, the interconnection between the booster fan 37, air pipe 38, hollow plate 35 and exhaust head 36 is utilized. The exhaust head 36 evenly discharges airflow into the purification filter seat 30 to generate bubbles, causing impurities and oil to adhere to the bubbles and float to the surface. This improves the aggregation effect of the flocculant on oil and suspended solids in the water, forming larger flocs, which further improves the cleaning effect of oil and impurities in the wastewater and improves the cleanliness of the treated seawater.

[0055] In addition to the isolation and sealing through the isolation seat 31, and the isolation of the flocs by the combination of the mesh cylinder 33 and the isolation filter screen 34, the purified seawater is discharged to the other side of the isolation seat 31. By opening the automatic switch valve 42, the treated seawater is discharged through the drain pipe 41. When the drive motor 32 drives the mesh cylinder 33 and the isolation filter screen 34 to rotate, the isolation filter screen 34 contacts the isolation seat 31 to clean the flocs on the surface of the isolation filter screen 34 and prevent the treated seawater from clogging the drain.

[0056] The generated flocs are discharged into the sediment storage base 40 for storage through the sediment discharge pipe 39 under the action of gravity.

[0057] After completing the marine ecological restoration operation, shut down all power equipment and valves, disassemble the equipment from the hull, clean components such as the sludge collection hopper 4, oil separation seat 18, and purification filter seat 30 to remove residual oil and flocs, check the wear of each component, and replace damaged components such as the oil suction belt 23 and the isolation filter screen 34 in a timely manner. Lubricate and maintain moving parts such as the hydraulic push rod 2, servo motor 12, and oil pump 14 to ensure the long-term stable operation of the equipment.

[0058] The oil-absorbing belt 23 is made of a material with high oil absorption and low water absorption, such as polypropylene fiber felt or polyester fiber felt, which can efficiently absorb oil stains while reducing water absorption and improving oil-stain separation efficiency.

[0059] The isolation filter 34 is woven from stainless steel wire, which has high filtration accuracy and strength, can effectively intercept lint, and has good corrosion resistance.

[0060] The floating buoy 10 is made of high-density polyethylene or polyvinyl chloride, which has good buoyancy and oil resistance, and can float stably on the sea surface and effectively surround oil pollution.

[0061] It is equipped with a PLC-based automated control system to achieve centralized control of marine ecological restoration equipment.

[0062] Beneficial effects: Through the coordinated work of the sludge collection hopper 4 and the oil sludge extraction component, the oil sludge on the sea surface can be quickly collected and initially separated, and the oil sludge can be extracted from the seawater for treatment. The surrounding and storing function of the floating lanyard 10 and the automatic winding and unwinding function of the winding component enable the equipment to adapt to oil pollution of different areas and ranges, efficiently collect oil sludge in the sludge collection hopper 4, and improve the oil sludge collection efficiency.

[0063] The rational design of components such as the oil-absorbing belt 23, diversion plate 19, sewage discharge trough 20, and scraper 24 in the oil-soil separation seat 18 ensures effective separation of oil and sewage, improving the thoroughness of oil separation. The multi-stage purification process in the purification filter seat 30, including the addition of flocculant, bubble flotation, and filtration by the isolation filter screen 34, further removes oil and impurities from the sewage, enabling the treated seawater to meet discharge standards and reducing the impact on the marine ecological environment.

[0064] The separated oil is collected in the oil collection seat 28 for subsequent recycling and reuse. The precipitated flocs are discharged into the sedimentation storage seat 40 for centralized treatment, thus avoiding secondary pollution.

[0065] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0066] In summary, the marine ecological restoration equipment in this embodiment integrates advanced mechanical, electrical, and chemical processing technologies, enabling efficient and automatic collection, separation, and purification of oil spills on the sea surface. It effectively solves the problems existing in the prior art and is an efficient, environmentally friendly, and reliable marine ecological restoration solution, which is of great significance for protecting the marine ecological environment and responding to marine oil pollution incidents.
