Description

Technical Field

[0001] This invention relates to a recovery towing device, specifically an integrated marine oil spill recovery towing device, belonging to the field of oil spill recovery technology. Background Technology

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called naturally occurring oily liquid minerals petroleum, combustible gases natural gas, and solid combustible fuel minerals bitumen. With deeper research into these minerals, it was recognized that they are all hydrocarbon compounds and interconnected in their formation, therefore they are collectively referred to as petroleum. Petroleum is a complex mixture consisting of gaseous, liquid, and solid hydrocarbon compounds found in nature, as well as small amounts of impurities. Therefore, petroleum extraction also includes natural gas extraction.

[0003] With the development of oil exploration and extraction technology and the limitation of onshore oil resources, offshore oil extraction has entered a period of rapid development. However, offshore oil extraction will cause certain pollution to the ocean, such as noise pollution from equipment, domestic waste pollution, industrial wastewater pollution, and oil spill pollution.

[0004] For example, marine oil spill pollution refers to the pollution of the ocean caused by the leakage of petroleum and its refined products during extraction, storage, and transportation. Oil spills from ships and blowouts in offshore oil fields are among the main causes of marine environmental pollution. Oil spills can have direct or indirect impacts on many aspects of the marine ecosystem, tourism, and aquaculture. First, after oil spills cover the water surface, the decrease in oxygen levels in the seawater, the chemical toxins from oil decomposition, and the adhesiveness of the oil cause mass deaths of marine life such as fish, shrimp, plankton, and seabirds, disrupting the ecological balance of the marine environment.

[0005] Therefore, oil spill recovery is an essential part of offshore oil extraction. Most existing oil spill recovery devices utilize floating bodies with oil-absorbing discs to collect crude oil from the sea surface, which is then scraped off. However, the discs agitate the oil slick while operating on the surface, accelerating its spread and increasing the area of ​​marine pollution, hindering oil recovery. Furthermore, these devices are slow, incomplete, and lack continuous operational capability. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to provide an integrated marine oil spill recovery and towing device to solve the above-mentioned problems. This addresses the issues in existing technologies, which mostly utilize a float with an oil-absorbing turntable to absorb crude oil from the sea surface and then scrape it off. However, when the turntable operates on the sea surface, it agitates the oil, accelerates its spread, expands the marine pollution area, hinders oil recovery, and results in slow operation, incomplete recovery, and poor continuous operation.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an integrated marine oil spill recovery towing device, comprising a towing vessel, an oil storage tank fixedly connected inside the towing vessel, a water pump installed on the top of the oil storage tank, an encoder fixedly connected to the top of the water pump, an inlet pipe, a filter box, a guide pipe, a telescopic pipe, and a float plate arranged on one side of the water pump, a waterproof motor and a drive shaft arranged inside the inlet pipe, filter media fixedly connected inside the filter box, a rotating circular plate, multiple oil-absorbing cotton, a short bend pipe, and an oil discharge pipe arranged inside the guide pipe, a solenoid valve and a flared pipe arranged inside the oil discharge pipe, a hydraulic cylinder and a squeezing plate arranged inside the short bend pipe, foam blocks installed inside the oil storage tank, and an L-shaped plate, an alarm button, and an alarm device arranged on the top of the oil storage tank.

[0010] Preferably, the inlet pipe is installed at the inlet end of the water pump, and one end of both the inlet pipe and the guide pipe extends into the filter box. The filter box is threadedly connected to the inlet pipe and the guide pipe by multiple mounting bolts. The filter media filters the seawater after the oil-absorbing cotton has filtered and intercepted the spilled oil, ensuring that the seawater is filtered clean, reducing impurities entering the water pump, and protecting the internal structure of the water pump. The filter media is placed between the inlet pipe and the guide pipe, which allows the assembled filter box and filter media to be separated, enabling the filter box and filter media to be disassembled and replaced quickly.

[0011] Preferably, multiple insulating blocks are fixedly connected between the waterproof motor and the water inlet pipe. The drive shaft is fixedly installed between the output end of the waterproof motor and the rotating circular plate. The drive shaft passes through the filter media and is rotatably connected to the filter media. The encoder controls the operation of the waterproof motor and controls the drive shaft to drive the rotating circular plate to rotate one-third of a revolution once, so that one of the oil-absorbing cottons rotates and moves between the short bend pipe and the oil drain pipe.

[0012] Preferably, the short bend is located on the side of the rotating plate near the water pump, and the short bend is fixedly connected to the water guide pipe. The oil drain pipe is located on the side of the rotating plate away from the water pump. The squeezing plate squeezes the oil-absorbing cotton to the side away from the water pump. Even if the spilled oil cannot completely enter the flared pipe, the spilled oil is still carried by the seawater flowing towards the water pump and captured and intercepted by the oil-absorbing cotton. One end of the oil drain pipe passes through the water guide pipe and extends into the oil storage tank.

[0013] Preferably, the rotating circular plate has multiple circular grooves, and multiple oil-absorbing cottons are respectively disposed in the multiple circular grooves and fixedly connected to the rotating circular plate. The rotating circular plate is rotatably installed inside the water guide pipe. The flared pipe is fixedly connected to the side of the solenoid valve near the rotating circular plate. The hydraulic cylinder works to push the extrusion plate to move, so that the extrusion plate moves to extrude the oil-absorbing cotton between the short curved pipe and the oil drain pipe, and extrudes the overflow oil absorbed by the oil-absorbing cotton into the flared pipe. The solenoid valve is fixedly connected to the inside of the oil drain pipe, and the extrusion plate is fixedly connected to the end of the hydraulic cylinder near the rotating circular plate. The overflow oil inside the flared pipe is guided into the oil storage tank through the solenoid valve and the oil drain pipe inserted into the oil storage tank.

[0014] Preferably, the telescopic pipe is fixedly connected between the float and the water guide pipe, the water guide pipe is L-shaped, a water inlet groove is opened on one side of the float, and floating airbags are fixedly connected to both sides of the float, so that the float is suspended on the sea surface and the water inlet groove is kept partially on the sea surface and partially in the seawater, so that the oil spill floating on the sea surface enters the water inlet groove.

[0015] Preferably, a support plate is fixedly connected between the water guide pipe and the tugboat, and a steel wire rope is fixedly connected to the top of the float. One end of the steel wire rope passes through the support plate, and a handle is fixedly connected to the other end of the steel wire rope. Pulling the steel wire rope allows the float, which is installed on the telescopic pipe, to move, causing the steel wire rope to drive the float upward and away from the sea surface. A hexagonal column is fixedly connected to the top of the oil tank. The float, which extracts the mixture of seawater and oil spill, is suspended on one side of the tugboat. This ensures that when the tugboat moves with the oil spill collected from the oil tank, the float does not come into contact with the seawater, thus guaranteeing the safety of the float.

[0016] Preferably, the top of the water pump is fixedly connected to an oil suction pipe and a sealing nut. The top of the foam block penetrates the sealing nut. The L-shaped plate is fixedly connected to the top of the foam block, preventing the foam block from falling completely into the oil storage tank. A U-shaped frame is fixedly connected to the top of the oil storage tank. The alarm button is fixedly connected to the top of the inner cavity of the U-shaped frame. One end of the L-shaped plate extends into the U-shaped frame, causing the foam block to leave the inside of the sealing nut. Then, a matching sealing bolt is rotated inside the sealing nut to seal the oil storage tank. The alarm is fixedly connected to one side of the U-shaped frame. The foam block pushes the L-shaped plate to move. The moving L-shaped plate presses the alarm button inside the U-shaped frame, alerting personnel inside the tugboat or at a distance that the oil storage tank is about to fill, ensuring that personnel can promptly handle any spilled oil stored in the tank.

[0017] Preferably, a transverse telescopic rod is installed at the outlet end of the water pump, and a drainage bend is rotatably connected to one end of the transverse telescopic rod. A rubber plate is sleeved on the outside of the drainage bend, and the rubber plate is fixedly connected to the tugboat.

[0018] Preferably, the bottom of the water pump is fixedly connected to both sides with supporting vertical plates, and an installation vertical plate is provided on one side of the supporting vertical plates. The installation vertical plate is fixedly connected to the oil storage tank, and a drainage bend that discharges seawater into the sea is rotatably installed via a horizontal telescopic rod. The supporting vertical plates and the installation vertical plates are bolted together, allowing the drainage bend, installed via the telescopic horizontal rod, to be moved into the tugboat. This prevents the drainage bend from being damaged during oil spills inside the oil storage tank while the tugboat is transporting the oil.

[0019] This invention provides an integrated towing device for marine oil spill recovery, which has the following advantages:

[0020] 1. This integrated marine oil spill recovery and towing device utilizes a pump that uses a recovery and filtration structure to collect oil spills from the sea surface into an oil storage tank. Oil-absorbing cotton is installed inside the water pipe to separate the oil from the seawater. Driven by a waterproof motor and drive shaft, the oil-absorbing cotton rotates between a short bend and a drain pipe. A hydraulic cylinder inside the short bend pushes a compression plate to squeeze the oil-absorbing cotton, guiding the collected oil through a flared pipe, a solenoid valve, and the drain pipe into the oil tank, completing the recovery and storage of the oil spill. The device can periodically squeeze and clean the oil-absorbing cotton to prevent excessive oil accumulation, which could reduce the filtration quality and ensure clean and rapid recovery of oil spills causing marine pollution. This enhances the continuous operation capability of the integrated oil spill recovery and towing device.

[0021] 2. This integrated marine oil spill recovery and towing device uses a floating plate suspended on the sea surface to absorb and collect the oil spill, avoiding any agitation or dispersion of the oil spill and preventing an increase in the area of ​​oil spill pollution during the recovery process. This ensures the effectiveness of marine pollution control efforts related to oil spill recovery. The waterproof motor is electrically connected to an encoder, and the waterproof motor and encoder together form a simple encoder motor. Pressing the control button on the top of the encoder once causes the encoder to control the waterproof motor to drive the drive shaft, which in turn rotates the rotating disc one-third of a revolution. This causes one of the oil-absorbing cotton pieces to rotate and move between the short bend and the oil drain pipe.

[0022] 3. This integrated marine oil spill recovery device uses a rotating bolt to loosen the filter box by connecting it to the water inlet and outlet pipes. By pulling the upper and lower parts of the filter box in opposite directions, the assembled filter box and filter media can be separated, allowing for rapid disassembly and replacement of the filter media. This ensures the filter media can be quickly cleaned and replaced as needed, maintaining its effectiveness in filtering seawater and protecting the water pump, thus reducing the probability of pump damage and minimizing economic losses.

[0023] 4. This integrated marine oil spill recovery and towing device uses a moving extrusion plate to compress the oil-absorbing cotton between the short curved pipe and the drain pipe, forcing the oil absorbed by the cotton into the flared pipe. Simultaneously, the solenoid valve connected to the flared pipe opens, allowing the oil inside the flared pipe to be guided into the oil storage tank through the solenoid valve and the drain pipe inserted into the tank. This completes the collection and storage of the oil absorbed by the cotton, ensuring its continuous working capacity and improving the continuous operational capability of the integrated marine oil spill recovery and towing device.

[0024] 5. This integrated marine oil spill recovery and towing device, by rotating and pushing the drain bend, can move the drain bend, which is installed via a telescopic horizontal extension rod, into the tugboat. This prevents the drain bend from being damaged during the transport of oil spills inside the storage tank, ensures the safety of parts during the movement of the tugboat, and reduces the cost of towing oil spills inside the storage tank.

[0025] 6. This integrated marine oil spill recovery and towing device suspends a float plate, which extracts the oil-water mixture, on one side of the towing vessel. This ensures the float plate does not come into contact with seawater when the towing vessel is moving to collect the spilled oil from its storage tank, guaranteeing its safety and reducing the possibility of damage. Rotating and pushing the drain pipe moves the drain pipe, which is connected to a retractable horizontal telescopic rod, into the towing vessel. This prevents damage to the drain pipe during the transport of the spilled oil from the storage tank, ensuring the safety of components during movement and reducing costs associated with towing the spilled oil from the storage tank.

[0026] 7. This integrated marine oil spill recovery towing device features a moving L-shaped plate that presses the alarm button inside the U-shaped frame. This activates the alarm device electrically connected to the button, alerting personnel inside the towing vessel or at a distance that the oil tank is about to fill. This ensures that personnel can promptly handle the oil spill stored in the tank and prevent oil spill recovery failure due to the tank being full. Attached Figure Description

[0041] This invention provides an integrated towing device for marine oil spill recovery.

[0042] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The system includes a tugboat 1, an oil tank 2 fixedly connected inside the tugboat 1, a water pump 3 installed on the top of the oil tank 2, an encoder 38 fixedly connected to the top of the water pump 3, an inlet pipe 4, a filter box 14, a water guide pipe 5, a telescopic pipe 6 and a float 7 on one side of the water pump 3, a waterproof motor 17 and a drive shaft 19 installed inside the inlet pipe 4, filter media 16 fixedly connected inside the filter box 14, a rotating circular plate 20, multiple oil-absorbing cotton 21, a short bend pipe 22 and an oil drain pipe 23 installed inside the water guide pipe 5, a solenoid valve 24 and a flared pipe 25 installed inside the oil drain pipe 23, a hydraulic cylinder 26 and a squeezing plate 27 installed inside the short bend pipe 22, a foam block 30 installed inside the oil tank 2, and an L-shaped plate 31, an alarm button 33 and an alarm 39 installed on the top of the oil tank 2.

[0043] Specifically, an oil storage tank 2 is installed inside the tugboat 1 to store the recovered spilled oil. An inlet pipe 4, a filter box 14, mounting bolts 15, a telescopic pipe 6, and a float 7 are sequentially installed on one side of the water pump 3. The recovery and filtration structure formed by the inlet pipe 4, filter box 14, mounting bolts 15, telescopic pipe 6, and float 7 works in conjunction with the water pump 3. The operating water pump 3 uses this recovery and filtration structure to recover the spilled oil from the sea surface into the oil storage tank 2. Furthermore, oil-absorbing cotton 21 is installed inside the water guide pipe 5 to trap the spilled oil. The oil-absorbing cotton 21 separates the spilled oil from the seawater, which is then pumped into the sea by the water pump 3 through the inlet pipe 4.

[0044] The oil-absorbing cotton 21, which traps the spilled oil, can be driven by the waterproof motor 17 and the drive shaft 19 to rotate between the short bend pipe 22 and the drain pipe 23. This causes the hydraulic cylinder 26 inside the short bend pipe 22 to push the extrusion plate 27 to squeeze the oil-absorbing cotton 21. The spilled oil collected by the oil-absorbing cotton 21 is then guided into the oil storage tank 2 through the flared pipe 25, the solenoid valve 24 that is in operation, and the drain pipe 23, thus completing the work of recovering and storing the spilled oil inside the oil storage tank 2. The oil-absorbing cotton 21, which absorbs and collects spilled oil, can be squeezed and cleaned regularly to prevent excessive oil absorption inside the cotton 21, which could reduce the quality of oil filtration and interception. This ensures clean oil spill recovery and rapid recovery of oil spills that cause marine pollution. It also improves the continuous working capacity of the integrated oil spill recovery and towing device, which consists of parts such as the towing vessel 1, oil storage tank 2, water pump 3, water inlet pipe 4, filter box 14, water guide pipe 5, telescopic pipe 6, float 7, short bend pipe 22, oil discharge pipe 23, solenoid valve 24, flared pipe 25, and hydraulic cylinder 26, for oil spill recovery.

[0045] Furthermore, the floating plate 7 suspended on the sea surface absorbs and collects the oil spill, avoiding any agitation or dispersion of the oil spill and preventing an increase in the area of ​​oil spill pollution during the oil spill recovery process, thus ensuring the success of marine pollution control efforts related to oil spill recovery.

[0046] Please refer to it again. Figure 1 , Figure 5 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13The inlet pipe 4 is installed at the inlet end of the water pump 3. Both the inlet pipe 4 and the guide pipe 5 extend to the inside of the filter box 14. Multiple mounting bolts 15 are threadedly connected between the filter box 14 and the inlet pipe 4 and the guide pipe 5. The filter media 16 is placed between the inlet pipe 4 and the guide pipe 5. Multiple insulating blocks 18 are fixedly connected between the waterproof motor 17 and the inlet pipe 4. The drive shaft 19 is fixedly installed between the output end of the waterproof motor 17 and the rotating circular plate 20. The short bend pipe 22 is placed on the side of the rotating circular plate 20 near the water pump 3. The short bend pipe 22 is fixedly connected to the guide pipe 5. The oil drain pipe 23 is placed on the rotating circular plate 20. The plate 20 is located away from the water pump 3. One end of the oil drain pipe 23 extends through the water guide pipe 5 and into the oil storage tank 2. The drive shaft 19 passes through the filter media 16 and is rotatably connected to the filter media 16. The rotating circular plate 20 has multiple circular grooves. Multiple oil-absorbing cotton 21s are respectively placed inside the multiple circular grooves and are fixedly connected to the rotating circular plate 20. The rotating circular plate 20 is rotatably installed inside the water guide pipe 5. The flared pipe 25 is fixedly connected to the side of the solenoid valve 24 near the rotating circular plate 20. The solenoid valve 24 is fixedly connected inside the oil drain pipe 23. The extrusion plate 27 is fixedly connected to the end of the hydraulic cylinder 26 near the rotating circular plate 20.

[0047] Specifically, a filter media 16 is installed between the water inlet pipe 4 and the water guide pipe 5. The filter media 16 filters the seawater after the oil-absorbing cotton 21 has filtered and intercepted the spilled oil, ensuring that the seawater is filtered clean, reducing the impurities entering the water pump 3, protecting the internal structure of the water pump 3, and ensuring the service life of the water pump 3.

[0048] A filter box 14 is fixedly sleeved on the outside of the filter media 16. By rotating the mounting bolts 15 installed between the filter box 14 and the water guide pipe 5 and the inlet pipe 4, the filter box 14 is loosened. Then, the upper and lower parts of the filter box 14 are pulled in opposite directions to separate the assembled filter box 14 and the filter media 16, completing the disassembly of the filter box 14 and the filter media 16. This allows for quick disassembly and replacement of the filter media 16. The filter media 16 can be quickly cleaned and replaced as needed, ensuring its effectiveness in filtering seawater and protecting the water pump 3, reducing the probability of pump 3 damage and minimizing economic losses.

[0049] A waterproof motor 17 is installed inside the water inlet pipe 4 via multiple insulating blocks 18. The drive shaft 19 installed at the output end of the waterproof motor 17 is fixedly connected to the rotating circular plate 20. When the waterproof motor 17 is working, it can drive the rotating circular plate 20 to rotate via the drive shaft 19. The rotating circular plate 20 drives the oil-absorbing cotton 21 to rotate one-third of a turn, so that one of the oil-absorbing cotton 21 rotates and moves between the short bend pipe 22 and the oil drain pipe 23.

[0050] Furthermore, the waterproof motor 17 is electrically connected to the encoder 38. The waterproof motor 17 and the encoder 38 form a simple encoder motor. Pressing the control button installed on the top of the encoder 38 once will cause the encoder 38 to control the waterproof motor 17 to work and control the drive shaft 19 to drive the rotating disc 20 to rotate one-third of a revolution once, causing one of the oil-absorbing cotton 21 to rotate and move between the short bend pipe 22 and the oil drain pipe 23.

[0051] When the waterproof motor 17 controls one of the oil-absorbing cotton 21 to rotate and move between the short bend pipe 22 and the oil drain pipe 23, the hydraulic cylinder 26 operates to push the extrusion plate 27 to move, causing the extrusion plate 27 to move and extrude the oil-absorbing cotton 21 between the short bend pipe 22 and the oil drain pipe 23, squeezing the overflow oil absorbed by the oil-absorbing cotton 21 into the flared pipe 25. At the same time, the solenoid valve 24 connected to the flared pipe 25 is opened, allowing the overflow oil inside the flared pipe 25 to be guided into the oil storage tank 2 through the solenoid valve 24 and the oil drain pipe 23 inserted into the oil storage tank 2. Complete the work of absorbing and storing the oil spill using the oil-absorbing cotton 21, ensuring the continuous working capacity of the oil-absorbing cotton 21, and improving the continuous working capacity of the integrated oil spill recovery and towing device formed by the towing vessel 1, oil storage tank 2, water pump 3, water inlet pipe 4, filter box 14, water guide pipe 5, telescopic pipe 6, float 7, short bend pipe 22, oil discharge pipe 23, solenoid valve 24, flared pipe 25, hydraulic cylinder 26 and other parts for marine oil spill recovery.

[0052] Furthermore, the extrusion plate 27 squeezes the oil-absorbing cotton 21 away from the water pump 3. Even if the spilled oil cannot completely enter the flared pipe 25, it is still carried by the seawater flowing towards the water pump 3 and captured and intercepted by the oil-absorbing cotton 21, preventing the spilled oil from entering the water pump 3. When the hydraulic cylinder 26 operates to drive the extrusion plate 27 back into the short bend pipe 22, the solenoid valve 24 stops working at the same time, causing the oil drain pipe 23 to return to a sealed state.

[0053] Please refer to it again. Figure 1 , Figure 2 , Figure 3 Figure 6 and Figure 9 The telescopic pipe 6 is fixedly connected between the float 7 and the water guide pipe 5. The water guide pipe 5 is L-shaped. A water inlet trough 8 is opened on one side of the float 7. Floating airbags 9 are fixedly connected to both sides of the float 7. A support plate 12 is fixedly connected between the water guide pipe 5 and the towing vessel 1. A steel wire rope 10 is fixedly connected to the top of the float 7. One end of the steel wire rope 10 passes through the support plate 12. A handle 11 is fixedly connected to one end of the steel wire rope 10. A hexagonal column 13 is fixedly connected to the top of the oil tank 2.

[0054] Specifically, a telescopic pipe 6 is fixedly connected between the water guide pipe 5 and the float 7, and a steel wire rope 10 is fixedly connected to the top of the float 7. By pulling the steel wire rope 10 through the handle 11, the float 7 installed on the telescopic pipe 6 can be moved, allowing the steel wire rope 10 to drive the float 7 upwards and away from the sea surface. After the handle 11 is attached to the outside of the hexagonal post 13, the float 7 is suspended above the sea surface. The float 7, which extracts the mixture of seawater and oil spill, can be suspended above the sea surface on one side of the tugboat 1. When the tugboat 1 is moving with the oil tank 2 to collect the spilled oil, the float 7 does not come into contact with the seawater, ensuring the safety of the float 7 and reducing the possibility of damage to the float 7.

[0055] Furthermore, the steel wire rope 10 passes through the support plate 12 fixed between the water pipe 5 and the tugboat 1, and one end of the steel wire rope 10 is fixedly connected to the handle 11. Therefore, the handle 11 and the support plate 12 cooperate to limit the steel wire rope 10, so that the handle 11 always stays in an operable position inside the tugboat 1.

[0056] Furthermore, a water inlet trough 8 is provided on one side of the float plate 7, and floating airbags 9 are fixedly connected to both sides of the float plate 7, so that the float plate 7 is suspended on the sea surface, and the water inlet trough 8 is kept partially on the sea surface and partially in the seawater, so that the oil spill floating on the sea surface enters the interior of the water inlet trough 8 and is extracted by the water pump 3 through the water inlet pipe 4, the water guide pipe 5, the telescopic pipe 6 and the float plate 7.

[0057] Please refer to it again. Figure 1 , Figure 5 , Figure 6 and Figure 7 The top of the water pump 3 is fixedly connected to the oil suction pipe 28 and the sealing nut 29. The top of the foam block 30 passes through the sealing nut 29. The L-shaped plate 31 is fixedly connected to the top of the foam block 30. The top of the oil storage tank 2 is fixedly connected to the U-shaped frame 32. The alarm button 33 is fixedly connected to the top of the inner cavity of the U-shaped frame 32. One end of the L-shaped plate 31 extends into the U-shaped frame 32. The alarm 39 is fixedly connected to one side of the U-shaped frame 32.

[0058] Specifically, a foam block 30 is installed inside the oil storage tank 2. When the oil overflows into the tank 2 and reaches a certain level, the overflow will cause the foam block 30 to float and move, pushing the L-shaped plate 31 to move. The moving L-shaped plate 31 presses the alarm button 33 inside the U-shaped frame 32, causing the alarm 39, which is electrically connected to the alarm button 33, to sound an alarm, reminding personnel inside the towing vessel 1 or at a distance from the towing vessel 1 that the oil storage tank 2 is about to be full. This ensures that personnel can promptly handle the overflow stored in the oil storage tank 2 and avoid failure to recover the overflow due to the tank 2 being full.

[0059] Furthermore, the L-shaped plate 31 is fixedly connected to the top of the foam block 30. The L-shaped plate 31, which is stuck on the top of the sealing nut 29, prevents the foam block 30 from falling completely into the oil tank 2. Pulling the L-shaped plate 31 causes the foam block 30 to leave the inside of the sealing nut 29. Then, the matching sealing bolt is rotated inside the sealing nut 29 to make the oil tank 2 enter a sealed state.

[0060] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A horizontal telescopic rod 34 is installed at the outlet end of the water pump 3. A drain bend 35 is rotatably connected to one end of the horizontal telescopic rod 34. A rubber plate is fitted on the outside of the drain bend 35. The rubber plate is fixedly connected to the towing vessel 1. Supporting vertical plates 36 are fixedly connected to both sides of the bottom of the water pump 3. An installation vertical plate 37 is provided on one side of the supporting vertical plate 36. The installation vertical plate 37 is fixedly connected to the oil storage tank 2. The supporting vertical plate 36 and the installation vertical plate 37 are installed together by bolts.

[0061] Specifically, a horizontal telescopic rod 34 is installed at the outlet of the water pump 3. A drainage bend 35, which discharges seawater into the sea, is installed by rotating the horizontal telescopic rod 34. Rotating the drainage bend 35 and pushing it allows the drainage bend 35, installed via the telescopic horizontal telescopic rod 34, to be moved into the tugboat 1. This prevents damage to the drainage bend 35 during oil spills inside the oil storage tank 2 while being transported by the tugboat 1. It ensures the safety of components in the integrated oil spill recovery and towing device, which consists of the tugboat 1, oil storage tank 2, water pump 3, water guide pipe 5, telescopic pipe 6, float 7, filter box 14, filter media 16, short bend 22, oil drain pipe 23, solenoid valve 24, flared pipe 25, and horizontal telescopic rod 34, during movement, reducing costs associated with towing oil spills inside the oil storage tank 2.
