Description

Technical Field

[0001] This application relates to the field of surface oil cleanup technology, and more specifically, to a marine oil spill cleanup vessel. Background Technology

[0002] At present, in marine oil spill cleanup operations, oil booms are the core protection and oil containment method commonly used. By building a physical barrier on the sea surface, they can effectively limit the spread of oil pollution and guide scattered oil pollution to a designated collection area. Subsequently, in conjunction with oil skimmers, oil absorption materials and other recovery equipment, the oil spill can be collected and cleaned up.

[0003] In the prior art, Chinese invention patent application number CN202510103885.6 discloses a marine oil spill cleanup vessel and a marine oil spill cleanup method. This technical solution uses a dedicated marine oil spill cleanup vessel as the operating carrier. Through the split-type hull structure set at the front of the vessel, the opening and closing action of the split-type hull is used to enclose and form a closed cleaning area. Then, the oil spill in the closed area is extracted by the suction mechanism of the split-type hull itself. Finally, the oil spill is efficiently separated from the seawater through the shipborne separation device, and the separated oil spill is stored in the dedicated collection tank of the cleanup vessel.

[0004] However, this existing technology still has significant technical shortcomings in actual cleanup operations: to ensure suction efficiency, the oil collection baffles mounted on the hull need to move towards the main hull to thicken and collect the oil in the cleanup area before suction and recovery. Although this design can improve the concentration and purity of the collected oil to some extent, the process of adjusting the oil collection baffles towards the main hull easily disturbs the sea surface in the cleanup area, causing violent local water fluctuations. This leads to the remixing of the previously separated oil and water, disrupting the stability of the oil layer and making it impossible to ensure that the required oil thickness for suction operations remains constant.

[0005] Furthermore, in this technical solution, the installation height and position of the detachable hull and its integrated floating suction device relative to the sea surface remain fixed, resulting in it only being able to accommodate oil spill layers of a specific thickness during cleanup operations. If factors such as sea state fluctuations or uneven oil diffusion prevent the oil collection baffle from increasing the oil thickness in the cleanup area to this specific suitable thickness, the suction efficiency and cleanup effect of the entire cleanup system will significantly decrease, severely impacting the stability and reliability of offshore oil spill cleanup operations. Summary of the Invention

[0014] Preferably, the passive gear is coaxially sleeved on the rotating shaft and meshes with the transmission gear.

[0015] Preferably, an L-shaped fixing member is fixedly connected to the bottom end of the first positioning plate. The L-shaped fixing member is used to fix the first suction component.

By utilizing the arc-shaped design of the suction ends of the first and second cleaning structures, the suction range during the sludge removal process can be enhanced. Compared with a straight suction port, the suction disturbance is reduced. Furthermore, the arc-shaped structure can guide the fluid to form a Venturi tube-like effect at the suction end, generating local negative pressure and actively drawing the surrounding oil and sludge towards the suction end.

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] like Figures 1-9 As shown, an oil spill cleanup vessel according to an embodiment of this application includes a cleanup vessel 1 and a cleanup device installed on the cleanup vessel 1. The cleanup device includes a power structure 2, two first cleaning structures 3 and two second cleaning structures 4 symmetrically arranged on both sides of the cleanup vessel 1, two suction pumps 5 and multiple storage tanks 6.

[0028] The power structure 2 is used to adjust the depth of each cleaning device relative to the sea surface and to adjust the opening and closing degree of the cleaning device at the front of the cleaning vessel 1. The first cleaning structure 3 and the second cleaning structure 4 on the same side are rotatably connected and have the same height. The first cleaning structure 3 is rotatably connected to the power structure 2 and rotates under the drive of the power structure 2. The second cleaning structure 4 can rotate autonomously relative to the first cleaning structure 3. The first cleaning structure 3 and the second cleaning structure 4 have the same structure, and their suction structures are connected in series. The suction ends of the first cleaning structure 3 and the second cleaning structure 4 are arc-shaped to increase the suction range. Two suction pumps 5 are installed on the cleaning vessel 1 and are connected to the two first cleaning structures 3 respectively to provide suction to the first cleaning structure 3 and the second cleaning structure 4 connected in series. Multiple storage cylinders 6 are connected in series, installed on the cleaning vessel 1, and are used to separate the oil and seawater mixture sucked by the first cleaning structure 3 and the second cleaning structure 4 and to store the separated oil.

[0029] In a specific embodiment of this application, the power structure 2 includes a lifting member 21, a wing plate 22 and two driving members 23. The lifting member 21 is fixed to the cleaning vessel 1, the wing plate 22 is fixed to the telescopic end of the lifting member 21 in the center, and the two driving members 23 are symmetrically arranged at both ends of the wing plate 22 and are used to drive the corresponding first cleaning structure 3 to rotate.

[0030] It should be noted that the lifting component 21 is an existing technology such as a hydraulic cylinder with telescopic function. The specific selection can be replaced according to the actual situation. The driving component 23 is a motor with a self-locking structure. Specifically, a commonly used worm gear reducer motor can be selected.

[0031] Among them, the two ends of the wing plate 22 are provided with rotating shafts 221, and the first cleaning structure 3 is rotatably sleeved on the rotating shafts 221, so that the axis of rotation of the first cleaning structure 3 is fixed.

[0032] Furthermore, the output end of the drive unit 23 is keyed to a drive gear 231, and a transmission gear 232 is rotatably connected to the wing plate 22. The transmission gear 232 meshes with the drive gear 231, and the transmission gear 232 is used to transmit rotational power to the first cleaning structure 3.

[0033] In a specific embodiment of this application, the first cleaning structure 3 includes a first suction component 31, a first main pipe 32, a first positioning plate 33, a first intercepting plate 34, and a first hydraulic cylinder 35. The first suction component 31 is fixedly mounted on the first positioning plate 33. The first main pipe 32 is arranged along the length of the first suction component 31, with one end connected to the suction pump 5 and the other end connected to the first suction component 31. One end of the first positioning plate 33 is rotatably connected to the wing plate 22, and the other end is rotatably connected to the second cleaning structure 4. The first intercepting plate 34 is mounted on the first positioning plate 33 and located on the side of the first suction component 31 closer to the cleaning vessel 1. One end of the first hydraulic cylinder 35 is rotatably connected to the wing plate 22, and the other end is rotatably connected to the first positioning plate 33.

[0034] The first suction component 31 has an arc-shaped surface 311 at its suction end, and multiple liquid inlets 312 are evenly arranged on the arc-shaped surface 311 along the length direction of the first suction component 31.

[0035] Furthermore, the first main pipe 32 is fixed to the first positioning plate 33. Multiple branch pipes 321 are evenly connected to the side wall of the first main pipe 32. The multiple branch pipes 321 are respectively connected to the first suction component 31, and a flow valve 322 is connected to the branch pipe 321. A connecting hose 323 is connected to one end of the first main pipe 32 connected to the second cleaning structure 4. The connecting hose 323 ensures that there will be no movement interference or pipe disconnection when the second cleaning structure 4 rotates relative to the first cleaning structure 3.

[0036] Understandably, when the suction pump 5 provides suction to the first main pipe 32, the multiple branch pipes 321 use the flow valves 322 connected to them to make the suction in each branch pipe 321 the same. In this way, the suction at the multiple liquid inlets 312 at the suction end of the first suction component 31 is formed as evenly as possible. Similarly, the second cleaning structure 4 also has the same suction through the connecting hose 323, which improves the cleaning effect of the first cleaning structure 3 and the second cleaning structure 4.

[0037] It should be noted that a passive gear 331 is fixedly connected to the end of the first positioning plate 33. The passive gear 331 is connected to the output end of the power structure 2 and is used to drive the first suction component 31, the first main pipe 32, the first positioning plate 33 and the first intercepting plate 34 to change angle relative to the cleaning vessel 1.

[0038] Specifically, the passive gear 331 is coaxially sleeved on the rotating shaft 221 and meshes with the transmission gear 232.

[0039] It can be understood that the starting drive component 23 can drive the first positioning plate 33 to rotate around the rotating shaft 221 through the active gear 231, the transmission gear 232 and the passive gear 331, so that the first cleaning structure 3 and the second cleaning structure 4 can be deployed relative to the cleaning vessel 1, and the cleaning range can be changed by changing the included angle between the two first cleaning structures 3 on both sides.

[0040] Furthermore, an L-shaped fixing member 332 is fixedly connected to the bottom end of the first positioning plate 33. The L-shaped fixing member 332 is used to fix the first suction member 31. The first intercepting plate 34 is disposed on the side wall of the L-shaped fixing member 332, and the bottom end of the first intercepting plate 34 is lower than the bottom end of the first suction member 31 to achieve the interception of oil. Multiple support rods 333 are evenly fixed between the L-shaped fixing member 332 and the first positioning plate 33. The support rods 333 are used to bring the first suction member 31 closer to the sea surface and reduce the travel range of the lifting member 21.

[0041] Among them, the top of the L-shaped fastener 332 is fixedly connected to the fixing plate 334, and multiple partitions 335 are evenly fixed between the fixing plate 334 and the L-shaped fastener 332. The first main pipe 32 passes through the multiple partitions 335 to position the first main pipe 32, and the first hydraulic cylinder 35 is rotatably connected to the center of the fixing plate 334.

[0042] It is understandable that the first hydraulic cylinder 35 can work with the drive component 23 to change the angle of the first cleaning structure 3 and the second cleaning structure 4, thereby reducing the load at the drive component 23.

[0043] It should be noted that, in the specific embodiments of this application, the second cleaning structure 4 includes a second suction component 41, a second main pipe 42, a second positioning plate 43, a second intercepting plate 44, and a second hydraulic cylinder 45. The second suction component 41 is fixedly connected to the second positioning plate 43. The second main pipe 42 is arranged along the length of the second positioning plate 43 and is connected to the connecting hose 323 and the second suction component 41. The second positioning plate 43 is hinged to the first positioning plate 33. The second intercepting plate 44 is arranged on one side of the second positioning plate 43. One end of the second hydraulic cylinder 45 is rotatably connected to the fixed plate 334 and the other end is rotatably connected to the second positioning plate 43.

[0044] It is understandable that the angle between the second cleaning structure 4 and the first cleaning structure 3 can be changed by the extension and retraction of the second hydraulic cylinder 45, such as... Figure 2 As shown, the second cleaning structure 4 is inclined outward along the forward direction of the cleaning vessel 1, which can increase the cleaning range and make the oil stains within the cleaning range converge towards the first cleaning structure 3.

[0045] It should be noted that a separator 61 is provided on the storage cylinder 6 connected to the suction pump 5. The separator 61 is connected to the liquid outlet of the suction pump 5 and separates the mixture of seawater and oil. The separated oil enters the storage cylinder 6, and the separated seawater is discharged to the sea surface.

[0046] Among them, the separator 61 can be a hydrocyclone separator in the prior art, which can quickly achieve the initial separation between seawater and oil.

[0047] In practical use, the cleaning vessel 1 travels to the area enclosed by the oil boom. Using the control equipment in the vessel's control room, it rotates the first cleaning structure 3 and the second cleaning structure 4 on both sides of the hull, opening them. Based on the actual thickness of the oil spill, it controls the extension and retraction of the lifting component 21, ensuring that the arc-shaped surfaces 311 of the first suction component 31 and the second suction component 41 are positioned above the oil layer. If the oil layer is relatively thin, the bottom of the arc-shaped surface 311 is submerged in water, while the top can be above the water surface. Then, the suction pump 5 is activated, using the first main pipe 32, connecting hose 323, and the second main pipe 42 to generate suction at the suction ends of the first and second suction components 31 and 41, extracting the oil spill. The extracted mixture is then pumped by the suction pump 5 into the separator 61 for oil and seawater separation. The separated oil is stored in the storage tank 6, and the separated seawater... The design of this scheme, which discharges the oil back into the sea, utilizes the angle changes of the first cleaning structure 3 and the second cleaning structure 4 on both sides of the cleaning vessel 1 to change the pumping range. The angle change of the second cleaning structure 4 relative to the first cleaning structure 3 can have a certain gathering effect on the oil slick as the cleaning vessel 1 moves forward, preventing the oil slick from escaping to both sides due to the movement of the vessel. The power structure 2 can adjust the depth of the first cleaning structure 3 and the second cleaning structure 4 on both sides of the cleaning vessel 1 relative to the sea surface, which is suitable for treating oil slicks of different thicknesses. The arc-shaped design of the suction end of the first cleaning structure 3 and the second cleaning structure 4 can enhance the suction range during the pumping process. Compared with a straight suction port, it can reduce suction disturbance, and the arc-shaped structure can guide the fluid to form a Venturi tube-like effect at the suction end, generating local negative pressure, actively gathering the surrounding oil slicks towards the suction end, and improving the pumping efficiency.

[0048] In related technologies, this type of offshore oil spill cleanup vessel is used because offshore oil spills usually mix with suspended impurities in seawater, such as marine organism debris and man-made garbage. During the pumping process, the mixture of oil and water impurities will adhere and accumulate at the inlet 312, eventually causing the inlet 312 to narrow or even completely block the channel, affecting the continuity of the pumping operation.

[0049] Example 2

[0050] According to some embodiments of this application, such as Figures 10-13As shown, a cleaning structure 7 is provided at the curved surface 311. The cleaning structure 7 utilizes the power generated when the liquid enters the inlet 312 to rotate and scrape the inlet 312 during the rotation process.

[0051] The cleaning structure 7 includes two fixed frames 71, a mounting shaft 72, multiple blades 73, and multiple cleaning components 74. The two fixed frames 71 are symmetrically fixed to both ends of the first suction component 31. The mounting shaft 72 is rotatably connected to the two fixed frames 71. The multiple blades 73 are evenly distributed on the side wall of the mounting shaft 72. The multiple cleaning components 74 are evenly distributed on the side wall of the mounting shaft 72 and elastically contact the curved surface 311.

[0052] Specifically, multiple blades 73 are spirally distributed along the axial direction of the mounting shaft 72, and the blades 73 are arranged radially inclined along the mounting shaft 72.

[0053] Understandably, the radial tilt of the blade 73 on the mounting shaft 72 reduces fluid interception. During the process of the fluid being drawn into the inlet 312, the fluid generates rotational power on the blade 73, thereby reducing fluid interception and avoiding affecting the efficiency of the suction operation.

[0054] Furthermore, it can be understood that the spiral distribution prevents the multiple blades 73 on the mounting shaft 72 from being subjected to force simultaneously, thus preventing the inability to generate the power to rotate the mounting shaft 72.

[0055] Furthermore, multiple cleaning components 74 are spirally distributed along the axial direction of the mounting shaft 72, and the length of the cleaning component 74 is greater than the distance between the mounting shaft 72 and the arc-shaped surface 311. The cleaning component 74 has a certain degree of elasticity and its diameter is smaller than the width of the liquid inlet 312.

[0056] It is understandable that the length of the cleaning component 74 is greater than the distance between the mounting shaft 72 and the curved surface 311. As a result, part of the cleaning component 74 will extend into the liquid inlet 312 as it rotates with the mounting shaft 72, thereby improving the cleaning effect on the liquid inlet 312.

[0057] Therefore, in practical use, the suction force formed at the inlet 312 is used to make the oil-water mixture flow into the inlet 312. During this process, a directional water flow will be formed at the mounting shaft 72. The water flow impacts the multiple spirally distributed blades 73 and generates thrust, thus causing the mounting shaft 72 to rotate. During the rotation, the multiple spirally distributed cleaning parts 74 on its side wall will rotate synchronously. The cleaning parts 74 follow the rotation of the mounting shaft 72 and perform a reciprocating scraping action on the arc surface 311 and the multiple inlets 312 on the arc surface 311. In this way, the suction channel of the inlet 312 can be cleaned. At the same time, since the entire cleaning structure 7 is set at the arc surface 311, during the rotation, it will also achieve a certain degree of pre-cleaning effect on the water flow entering the inlet 312 through the multiple cleaning parts 74.

[0058] In related technologies, this type of marine oil spill cleanup vessel, due to the varying thickness of oil spills at sea and the gradual thinning of oil spills within the oil boom area as the cleanup work progresses, and the fixed position of the first interceptor plate 34 extending into the water, will not always maintain a high efficiency in intercepting and gathering oil spills during the vessel's operation.

[0059] Example 3

[0060] According to some embodiments of this application, such as Figure 14 As shown, a plurality of active telescopic components 336 are evenly arranged on the fixed plate 334. One end of the plurality of active telescopic components 336 is fixed to the fixed plate 334, and the other end of the active telescopic components 336 is fixed to the first intercepting plate 34. The first intercepting plate 34 changes the height of its bottom end relative to the first suction component 31 by the telescopic changes of the active telescopic components 336.

[0061] The first interceptor plate 34 and the L-shaped fixing member 332 are in sliding fit.

[0062] Specifically, multiple passive telescopic components 337 are evenly arranged on the fixed plate 334. The multiple passive telescopic components 337 correspond one-to-one with multiple active telescopic components 336. The other end of the passive telescopic component 337 is fixed to the first intercepting plate 34.

[0063] It should be noted that the active telescopic component 336 can be made of existing technologies such as hydraulic cylinders, while the passive telescopic component 337 can be made of two round rods that are slidably sleeved together and have an elastic reset function.

[0064] Therefore, in practical use, the depth of the first suction component 31 and the second suction component 41 in the water surface is adjusted in real time by the lifting component 21 according to the actual thickness of the oil spill. At the same time, the height of the bottom of the first intercepting plate 34 and the second intercepting plate 44 relative to the bottom of the first suction component 31 and the second suction component 41 is adjusted in real time by the extension and retraction of the active telescopic component 336. For example, when the oil spill layer is relatively thick, the first intercepting plate 34 and the second intercepting plate 44 can be lowered relatively. When the oil spill layer is gradually thinning as the cleaning action is performed, the first intercepting plate 34 and the second intercepting plate 44 can be raised relatively. This reduces the disturbance to the water body caused by the first intercepting plate 34 and the second intercepting plate 44 being driven by the forward movement of the boat, and reduces the fluctuation of the oil spill layer.

[0065] It should be noted that the specific models and specifications of the cleaning vessel 1, drive component 23, first hydraulic cylinder 35, active telescopic component 336, second hydraulic cylinder 45, suction pump 5, and separation component 61 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0066] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
