Description

Technical Field

[0001] This application relates to the field of oil spill recovery, and particularly to an oil absorption structure and a water surface oil spill recovery device. Background Art

[0002] There are already many technologies for dealing with marine oil spill incidents, mainly focusing on physical adsorption, chemical absorption and oxidation combustion, biological degradation, etc. Among them, physical absorption and chemical absorption methods are common methods with the least environmental pollution. The adsorption method can achieve efficient oil-water separation of oil substances from seawater, thereby removing the polluted oil from the sea area. There are various existing adsorption devices, but they all have problems to a certain extent, such as a small effective adsorption range, poor continuous operation ability, and being greatly affected by tides and waves, resulting in low recovery efficiency of oil spill operations. At the same time, the uncertainty of the viscosity of the spilled oil affects the adsorption efficiency, resulting in low single-operation efficiency. Summary of the Utility Model

[0003] In order to solve at least one of the above problems, this application provides an oil absorption structure; and based on this oil absorption structure, a water surface oil spill recovery device is provided.

[0004] In a first aspect, this application provides an oil absorption structure, adopting the following technical solution:

[0005] An oil absorption structure includes a connecting member and at least two oil absorption units. Two adjacent oil absorption units are connected by the connecting member. The connecting member includes a first connecting unit and a second connecting unit arranged facing each other. The first connecting unit and the second connecting unit each independently include a fixing part, a slide rail, at least two sliding parts and at least four positioning parts. The slide rail is arranged on the fixing part. The sliding parts and the positioning parts are respectively slidably arranged on the slide rail. The positioning parts are respectively arranged on both sides of the sliding part along the sliding direction of the slide rail. The sliding part is clamped to the slide rail by the sliding of the positioning parts on both sides; at least two of the sliding parts are sequentially arranged at intervals, so that a preset-spacing clamping position is formed between the two positioning parts between two adjacent sliding parts; the sliding parts in the first connecting unit and the sliding parts in the second connecting unit are staggered. The sliding parts in the first connecting unit are clamped in the clamping positions in the second connecting unit, and the sliding parts in the second connecting unit are clamped in the clamping positions in the first connecting unit. By adjusting the sizes of the clamping positions in the first connecting unit and the clamping positions in the second connecting unit, a preset gap is formed between the sliding parts in the first connecting unit and the sliding parts in the second connecting unit arranged adjacent to each other. The size of the gap is greater than 0 and less than the height of the adjacent sliding part along the direction perpendicular to the slide rail.

[0006] By adopting the above technical solution, the oil absorption structure is formed by connecting two adjacent oil absorption units through a connecting piece. In the first connecting unit and the second connecting unit, the slide rail is fixed on the fixed part, and the sliding part is embedded on the slide rail and can move freely along the slide rail. The sliding part can be a toothed structure. The sliding part is fixed at a preset position on the slide rail through the positioning part, so as to form a clamping position with a preset distance between two adjacent sliding parts. The sliding parts in the first connecting unit and the sliding parts in the second connecting unit are staggered and clamped in the corresponding clamping positions. Due to the existence of the clamping positions between the sliding parts, at this time, by adjusting the sizes of the clamping positions in the first connecting unit and the clamping positions in the second connecting unit, a preset gap is formed between the sliding parts in the adjacent first connecting unit and the sliding parts in the second connecting unit, and the size of the gap is controlled to be greater than 0 and less than the height of the adjacent sliding parts in the direction perpendicular to the slide rail, that is, 0 (excluding) to the height dimension when the adjacent sliding parts coincide, so that a certain bending angle is formed between multiple oil absorption units (when applied to oil removal on the water surface, multiple oil absorption units float on the water surface at a certain bending angle), and then the overall oil absorption structure is controlled to be bent at a certain angle. On the one hand, the single oil removal range of the oil absorption structure can be controlled, and on the other hand, the oil absorption structure can be freely shaken within a certain range, which has a good buffering effect on the changes of sea waves and tides, that is, it resists the movement of the oil absorption structure caused by the tidal changes.

[0007] Preferably, the oil absorption unit includes a mesh-shaped accommodating part and an oil absorption matrix wrapped in the accommodating part. The fixed parts in the first connecting unit and the fixed parts in the second connecting unit are respectively arranged in one-to-one correspondence with two adjacent oil absorption units and are respectively connected to the respective accommodating parts in two adjacent oil absorption units in one-to-one correspondence.

[0008] Preferably, the oil absorption matrix is a three-dimensional porous structure.

[0009] By adopting the above technical solution, as a specific structural example, the oil absorption unit includes a mesh-shaped accommodating part and an oil absorption matrix wrapped in the accommodating part. The oil absorption matrix is a three-dimensional porous structure. An existing three-dimensional structure sponge with oleophilic and hydrophobic properties can be selected, especially a three-dimensional structure sponge with better oil absorption performance after modification. More specifically, the oil absorption matrix is a material with high oleophilic and hydrophobic properties obtained by graphene loading modification on a three-dimensional structure sponge. The sponge material can be melamine, polyurethane, etc. The interfacial water contact angle of this material is between 120-180°. The accommodating part is a mesh structure with large pores (round holes, square holes or other irregular shapes with an average pore diameter of 1-10 mm) and high strength (tear strength greater than 50 MPa). The strength and pore size that meet the requirements can be selected according to the actual situation. The accommodating part fixes the oil absorption matrix therein, ensuring that the overall oil absorption structure has high toughness and high strength, and at the same time has high oil absorption performance.

[0010] Preferably, at least three of the oil absorption units are arranged in sequence and connected in sequence to form the strip-shaped oil absorption structure.

[0011] Preferably, the number of the connecting pieces is at least two, and at least three oil absorption units extend along the length direction of the oil absorption unit and are connected in sequence through the connecting pieces.

[0012] By adopting the above technical solution, as a specific structural example, multiple oil absorption units are arranged in sequence respectively. For example, multiple oil absorption units extend along their respective length directions and are arranged in sequence. Among the multiple oil absorption units, two adjacent oil absorption units are connected to each other along their respective width directions through a connecting piece. The fixing part in the first connecting unit of each connecting piece is connected to the accommodating part in one of the two adjacent oil absorption units, and the fixing part in the second connecting unit is connected to the accommodating part in the other oil absorption unit among the two adjacent oil absorption units. The multiple sliding parts in the first connecting unit and the multiple sliding parts in the second connecting unit are staggered, and the multiple sliding parts in the first connecting unit correspond to the multiple clamping positions in the second connecting unit one by one and are respectively clamped in the multiple clamping positions in the second connecting unit. The multiple sliding parts in the second connecting unit correspond to the multiple clamping positions in the first connecting unit one by one and are respectively arranged in the multiple clamping positions in the first connecting unit, thereby realizing the sequential connection of multiple oil absorption units to form a strip-shaped oil absorption structure.

[0013] In a second aspect, the present application provides an oil spill recovery device on the water surface, adopting the following technical solution:

[0014] An oil spill recovery device on the water surface includes the above-mentioned oil absorption structure.

[0015] By adopting the above technical solution, applying the above-mentioned oil absorption structure to the treatment of oil spills on the water surface, due to the design of the connecting piece in the oil absorption structure, the oil absorption structure can float on the water surface at a certain bending angle, can control the single oil removal range of the oil absorption structure, and can realize the free swaying of the oil absorption structure within a certain range, having a good buffering effect on the changes of sea waves and tides.

[0016] Preferably, it further includes a hull and a winding device. At least two of the oil absorption units are arranged in sequence and connected in sequence to form the strip-shaped oil absorption structure. The winding device includes a driving member and a winding shaft. The oil absorption structure is connected to the winding shaft along the width direction. The driving member drives the winding shaft to rotate clockwise or counterclockwise, driving the oil absorption structure to be released or wound along the length direction.

[0017] By adopting the above technical solution, as a structural example, a retracting device is added. The retracting device includes a driving member and a retracting shaft. The retracting shaft is arranged on the driving output shaft of the driving member. The driving member drives the retracting shaft to rotate forward and backward, so as to realize the two operations of releasing and retracting the oil absorption structure along the length direction. Both the driving member and the retracting shaft can be fixed on the hull, or a retracting frame is added. The retracting frame is fixed on the hull, and the driving member and the retracting shaft are both arranged on the retracting frame.

[0018] Preferably, a regeneration device is further included. The regeneration device includes a regeneration frame, a first extrusion roller and a second extrusion roller. The first extrusion roller and the second extrusion roller are sequentially distributed along the height direction of the regeneration frame, and the roller surfaces of the first extrusion roller and the second extrusion roller face each other. The first extrusion roller and the second extrusion roller are respectively movably arranged on the regeneration frame, and a preset extrusion space is provided between the first extrusion roller and the second extrusion roller.

[0019] By adopting the above technical solution, as a structural example, the above regeneration device is added. The regeneration device includes a first extrusion roller and a second extrusion roller both arranged on the regeneration frame. A preset extrusion space is provided between the first extrusion roller and the second extrusion roller. The strip-shaped oil absorption structure passes through this extrusion space. As the first extrusion roller and the second extrusion roller roll, the oil substances adsorbed in the oil absorption structure are squeezed out. The relative positions of the first extrusion roller and the second extrusion roller can be adjusted to apply different pressures to the strip-shaped oil absorption structure. More specifically, an oil discharge pipe and a regeneration control member can also be added. The oil discharge pipe and the regeneration control member can both be arranged on the hull or directly integrated on the regeneration frame. The inlet of the oil discharge pipe is correspondingly arranged at the extrusion position where the oil absorption structure is squeezed by the first extrusion roller and the second extrusion roller (i.e., corresponding to the extrusion space). An open structure such as a funnel or a deflector for facilitating the collection of the squeezed oil substances can also be arranged at the inlet of the oil discharge pipe. An oil storage device for storing the oil substances can be added at the outlet of the oil discharge pipe, so as to recover the oil substances adsorbed by the oil absorption structure from the sea area. The squeezed oil substances are discharged through the oil discharge pipe to the oil storage device for collection. The operation of the first extrusion roller and the second extrusion roller can be controlled by the regeneration control member to realize the opening, stopping and process adjustment of the extrusion operation.

[0020] Preferably, a traction device is further included. The traction device includes a drone, and an oil content detection device and a clamping member are arranged on the drone.

[0021] By adopting the above technical solution, as a structural example, the above traction equipment is added, and the traction equipment includes a drone, such as an existing automatic cruising drone, which is equipped with an oil content detection device, and the oil content of the surrounding sea area is detected by the oil content detection device to determine whether to perform oil removal operations. The drone is also equipped with a clamping member for clamping the oil absorption structure to be towed. The specific location of the oil removal area can be determined by the cruising of the drone, and the oil absorption structure can be clamped by the clamping member, and the strip-shaped oil absorption structure can be released to the specified location in a direction.

[0022] Preferably, it also includes a monitoring device and / or a control system. The monitoring device is respectively provided on both sides of the hull, and the control system is respectively electrically connected to at least one of the winding device, the regeneration device, the drone, and the oil content detection device.

[0023] By adopting the above technical solution, as a structural example, additional monitoring equipment is installed on both sides of the hull. The monitoring equipment can select the existing 360° high-definition monitoring camera to remotely present the entire situation of the oil removal area. The moving direction and speed of the hull can be comprehensively judged based on the observation of the processing situation by the monitoring equipment. Furthermore, a control system can be added, and the control system can be electrically connected to at least one of the monitoring equipment, the drone in the traction equipment, the oil content detection machine, the reeling equipment, and the regeneration equipment, so as to realize the automatic control of the surface oil spill recovery device.

[0024] In summary, this application has the following beneficial effects:

[0025] 1. The oil absorption structure of the present application, through the design of the connecting piece in the oil absorption structure, makes a certain bending angle between the multiple oil absorption units, thereby controlling the bending of the entire oil absorption structure at a certain angle, which can control the single oil removal range of the oil absorption structure on the one hand, and resist the movement of the oil absorption structure affected by tidal changes on the other hand;

[0026] 2. The surface oil spill recovery device of the present application applies the above-mentioned oil absorption structure to the surface oil spill recovery process. Due to the design of the connecting parts in the oil absorption structure, the oil absorption structure can float on the water surface at a certain bending angle, and the single oil removal range of the oil absorption structure can be controlled, and the free shaking of the oil absorption structure within a certain range can be realized, which has a good buffering effect on waves and tidal changes.

[0046] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0047] Embodiment

[0048] Refer to the attached Figures 1-12 , in which, throughout all these views, the same reference numerals denote corresponding components. One implementation manner of the oil absorption structure shown according to this embodiment can be seen in Figures 1-4 , 9-12, and one implementation manner of the oil spill recovery device shown according to this embodiment can be seen in Figures 5-8 . It should be understood that the oil absorption structure and the oil spill recovery device according to the present application can be used in all application scenarios where oil spill treatment and oil substance recovery are required in water environments such as rivers, lakes, and seas.

[0049] As Figures 1-2 shown, the oil absorption structure 10 of this embodiment includes: a connecting member 1 and a plurality of oil absorption units 2. The plurality of oil absorption units 2 extend along their respective length directions and are arranged in sequence. Adjacent two oil absorption units 2 are connected by the connecting member 1 along their respective width directions, thereby forming a strip-shaped oil absorption structure.

[0050] Continue to refer to Figures 1-2 , the oil absorption unit 2 includes a mesh-shaped accommodating member 21 and an oil absorption matrix 22 wrapped in the accommodating member 21. The oil absorption matrix 22 of this embodiment is a material with oleophilic and hydrophobic properties obtained by graphene loading modification on a three-dimensional structure sponge. The sponge material is melamine or polyurethane, and its interfacial water contact angle is between 120-180°. The accommodating member 21 of this embodiment is a large-pore and high-strength mesh structure. In the mesh-shaped accommodating member, it can be designed as round holes, square holes or other irregular shapes with an average pore diameter of 1-10 mm, and the tear strength is greater than 50 MPa. Fixing the oil absorption matrix in the mesh-shaped accommodating member ensures that the overall oil absorption structure has good toughness and strength, and at the same time has excellent oil absorption performance.

[0051] Refer to Figure 2 , the connecting member 1 includes a first connecting unit 11 and a second connecting unit 12 arranged opposite to each other. Refer to Figures 3-4The first connection unit 11 and the second connection unit 12 each independently include a fixing portion 13, a slide rail 14, at least two sliding portions 15 (two are shown in the figure) and at least four positioning portions 16 (four are shown in the figure). The sliding portion 15 of this embodiment is a U-shaped tooth structure, and the positioning portion 16 is selected from the existing slide rail buckle. Figures 3-4 As shown, in two adjacent oil suction units 2, the fixing portion 13 in the first connecting unit 11 is sewn and connected to the receiving member 21 in one of the oil suction units 2, and the fixing portion 13 in the second connecting unit 12 is sewn and connected to the receiving member 21 in the other oil suction unit 2. The slide rail 14 in the first connecting unit 11 is fixed on the fixing portion 13 in the first connecting unit 11, and the slide rail 14 in the second connecting unit 12 is fixed on the fixing portion 13 in the second connecting unit 12. In the first connecting unit 11 and the second connecting unit 12, the two sliding portions 15 of each are slidably embedded in the respective slide rails 14, and can move freely along the slide rails 14. A positioning portion 16 is correspondingly provided at both ends of each sliding portion 15, and each sliding portion 15 is fixed to a designated position of the slide rail 14 by the two positioning portions 16 provided at its two ends. Taking the first connecting unit 11 as an example, a spacing is formed between the two sliding portions 15 in the first connecting unit 11, as shown in FIG. Figures 3-4 As shown, two positioning parts 16 are arranged between the two sliding parts 15, and a preset spacing is formed between the two positioning parts 16. Similarly, in the second connecting unit 12, a spacing is formed between the two sliding parts 15, and two positioning parts 16 are arranged between the two sliding parts 15, and a preset spacing is formed between the two positioning parts. The sliding parts 15 in the first connecting unit 11 and the sliding parts 15 in the second connecting unit 12 are staggered, and the sliding parts 15 in the first connecting unit 11 are clamped in the clamping position in the second connecting unit 12, and the sliding parts 15 in the second connecting unit 12 are clamped in the clamping position in the first connecting unit 11. At this time, by adjusting the position of the positioning parts 16, the size of the clamping position in the first connecting unit 11 and the size of the clamping position in the second connecting unit 12 are adjusted, so that there is a preset gap between the sliding parts 15 in the first connecting unit 11 and the sliding parts 15 in the second connecting unit 12 that are adjacently arranged, and the size of the gap is 0 (not included) to the height dimension of the overlap of the adjacent sliding parts. Due to the existence of the gap, the oil absorption structure 10 can be controlled to achieve a certain angle of bending, which can control the single oil removal range of the oil absorption structure 10 on the one hand, and can achieve free shaking of the oil absorption structure 10 within a certain range on the other hand, which has a good buffering effect on the changes of waves and tides. The sliding part 15 in the adjacent first connecting unit 11 and the sliding part 15 in the second connecting unit 12 are both tooth-like structures with arc-shaped ends. The arc-shaped ends can avoid wear when the sliding part 15 contacts during bending, and at the same time, the oil absorption units can be bent more smoothly.

[0052] See alsoFigure 3 , there is a preset gap between the sliding parts 15 in the adjacent first connecting unit 11 and the sliding parts 15 in the second connecting unit 12. The size of the gap is greater than 0 and less than the height of the adjacent sliding parts along the direction perpendicular to the slide rail, that is, from 0 (excluding) to the height dimension when the adjacent sliding parts coincide. Now, the specific principle that the existence of this gap enables the oil absorption structure 10 to be bent at a certain angle is explained as follows:

[0053] Assume the extreme case: when the distance between the sliding part 15 in the first connecting unit 11 and the sliding part 15 in the second connecting unit 12 is 0 ( Figure 9 ), there is no bending margin between two adjacent oil absorption units 2. Therefore, the included angle between the two oil absorption units 2 is 180°, which is a straight line. Then, more oil absorption units 2 cannot form a circle.

[0054] When the distance between the sliding part 15 in the first connecting unit 11 and the sliding part 15 in the second connecting unit 12 increases, the inclination of the fixed part can be realized, and the inclination angle is α ( Figure 11 ), so that the bending angle θ = 180° - α can be realized between the oil absorption units 2, thus < 180° ( Figure 12 ). The formula for the radius of the oil removal circle enclosed by the belt-shaped oil absorption structure is:

[0055] When the distance between the sliding part 15 in the first connecting unit 11 and the sliding part 15 in the second connecting unit 12 is the maximum, the bending degree is the largest, the α angle is the largest, and r is the smallest;

[0056] When the distance between the sliding part 15 in the first connecting unit 11 and the sliding part 15 in the second connecting unit 12 decreases, α decreases and r increases;

[0057] When the distance between the sliding part 15 in the first connecting unit 11 and the sliding part 15 in the second connecting unit 12 is 0, α = 0 and r is infinite.

[0058] As Figure 5 shown, the surface oil spill recovery device of this embodiment includes: a hull 20, an oil absorption structure 10, a traction device 50, a winding device 30, a regeneration device 40, an oil storage device 45, a monitoring device 60, and a control system (not marked in the figure). The oil absorption structure 10, the traction device 50, the winding device 30, the regeneration device 40, the oil storage device 45, the monitoring device 60, and the control system are all carried on the hull 20, and the hull 20 is responsible for transporting them to the designated oil removal area.

[0059] The monitoring device 60 is installed on both sides of the hull. The monitoring device 60 of this embodiment is a commercially available 360° high-definition monitoring camera, which can remotely transmit and present all situations of the oil removal area.

[0060] The traction device 50 in this embodiment includes a drone 51 with automatic cruise function. An oil content detection device 52 is installed on the drone 51. The oil content detection device 52 can select existing devices with oil content detection function. Through the cruise of the traction device 50, the specific position of the oil removal area can be determined, and the width direction of the oil absorption structure 10 can be clamped by a clamping member (not shown) on the drone 51, and then the oil absorption structure can be released along the length direction of the oil absorption structure 10 to a specified position.

[0061] When there is an emergency oil removal requirement in the water area, the hull 20 sails to the specified position and stops. Then, a clamping member (such as a claw / hook, etc.) in the traction device 50 clamps the accommodating member 21 in any one of the oil absorption units 2 of the oil absorption structure 10. Then, the traction device 50 enters the water from the bow. The drone 51 of the traction device 50 is an automatic cruise ship (drone), and it travels according to the command route to arrange the oil absorption belt at the specified position.

[0062] During the process of arranging the belt-shaped oil absorption structure 10, the traction device 50 and the hull 20 do not move simultaneously;

[0063] When the belt-shaped oil absorption structure 10 is completely placed at the specified position, the drone 51 returns to the tail of the hull 20 under the command. Then, the oil absorption structure 10 at the head clamped by the clamping member is connected end to end with the oil absorption structure at the tail of the hull 20 that has not been put into the water area (the connection method is the connection between the first connection unit and the second connection unit), and the belt-shaped oil absorption structure forms an oil removal circle. Then, the traction device 50 travels to the bow and returns to the warehouse.

[0064] See Figure 6 The winding device 30 includes a driving member 31, a winding shaft 32, and a winding frame 33. The driving member 31 and the winding shaft 32 are respectively arranged on the winding frame 33. The driving member 31 can be a common motor that meets the power requirements. The driving output shaft of the driving member 31 is connected to the winding shaft 32 to drive the winding shaft 32 to rotate forward and backward, so as to realize two operations of releasing and winding the belt-shaped oil absorption structure 10 along the length direction.

[0065] In this embodiment, during the feeding process of the winding device 30, the belt-shaped oil absorption structure gradually winds around the winding shaft 32 as the winding shaft 32 rotates. A limiter is arranged on the winding shaft 32 according to the width of the belt-shaped oil absorption structure 10 to prevent winding deviation. A flattening device is arranged directly above the winding device 30. The flattening device is composed of a soft steel wire and a flattening roller. At the initial stage of winding, the soft steel wire is in a free elongation state. As the winding progress advances, the flattening roller is gradually lifted by the belt-shaped oil absorption structure 10, and the soft steel wire is in a free and unloaded state. The flattening roller is a hollow metal roller, which relies on gravity to flatten the irregular belt-shaped oil absorption structure 10 to prevent the problems of winding and knotting of the belt-shaped oil absorption structure 10.

[0066] See Figure 7 , the regeneration device 40 includes a regeneration frame 41, a first extrusion roller 42, a second extrusion roller 43, an oil discharge pipe 44 and a regeneration control member 46. The first extrusion roller 42 and the second extrusion roller 43 are sequentially distributed along the height direction of the regeneration frame 41. See Figure 7 , the first extrusion roller 42 is located above the second extrusion roller 43, and the roller surfaces of the first extrusion roller 42 and the second extrusion roller 43 are arranged facing each other. The first extrusion roller 42 and the second extrusion roller 43 are respectively movably arranged on the regeneration frame 41, and a preset extrusion space is provided between the first extrusion roller 42 and the second extrusion roller 43. Different extrusion spaces can be obtained by adjusting the positions of the first extrusion roller 42 and the second extrusion roller 43, so as to apply different pressures to the strip-shaped oil absorption structure 10, thereby recovering the oil substances adsorbed by the oil absorption structure 10 from water environments such as the sea area. The regeneration control members 45 are all arranged on the regeneration frame. The inlet of the oil discharge pipe 44 is correspondingly arranged at the extrusion position where the oil absorption structure 10 is extruded by the first extrusion roller 42 and the second extrusion roller 43( Figure 7 in the figure is the lower position corresponding to the extrusion space), and the oil storage device 45 is arranged at the outlet of the oil discharge pipe 44 for storing oil substances. The extruded oil substances are discharged through the oil discharge pipe 44 to the oil storage device 45 for collection. Since the use of two relatively arranged rollers to achieve rolling extrusion and the control of the opening and stopping of the rollers by the control device are all conventional electromechanical designs, the specific structural setting parameters and electrical connection methods of the first extrusion roller, the second extrusion roller and the regeneration control member are not described in detail here.

[0067] The control system (not shown) of this embodiment is electrically connected to the monitoring device 60, the drone 51 in the traction device 50, the oil content detection device 52, the winding device 30 and the regeneration device 40 at the same time, and can realize the automatic control of the surface oil spill recovery device.

[0068] The working principle of the surface oil spill recovery device of this embodiment is specifically as follows:

[0069] After an oil spill accident occurs, the hull 20 is equipped with a strip-shaped oil-absorbing structure 10, a traction device 50, a winding device 30, a regeneration device 40, an oil storage device 45, and a monitoring device 60. The monitoring device 60 transmits all the image data to the onshore control system, and the hull 20 is navigated to the designated oil removal area through remote control. Then, the traction device 50 is put into operation, and the oil content detection device 52 detects the oil content in the surrounding sea area and transmits the data remotely to the onshore control system to determine whether to perform oil removal operations. If the oil content does not meet the treatment requirements, the hull 20 is navigated to the next oil removal area. If it is determined that the treatment requirements are met, the clamping member (not shown) of the traction device 50 clamps the oil-absorbing structure 10 to be towed. At the same time, the strip-shaped oil-absorbing structure 10 is connected to the winding shaft 32 on the winding device 30, and the strip-shaped oil-absorbing structure 10 is towed to the target position according to the set program through the automatic cruise of the traction device 50. Then, the traction device 50 returns to standby on the other side of the hull 20, and the strip-shaped oil-absorbing structure 10 is connected to the inlet end of the regeneration device 40, that is, connected to the extrusion space between the first extrusion roller 42 and the second extrusion roller 43, and the oil-absorbing structure 10 passes through the extrusion space to form a loop (as Figure 8 shown). At this time, the strip-shaped oil-absorbing structure 10 floats on the water surface at a certain bending angle with the oil-absorbing units 2 through the internal connecting members 1. The size of the bending angle is mainly controlled by the gap between the sliding parts 15, and the gap is realized by the positioning part 16 fixing the sliding parts 15 at different positions on the slide rail 14, and the slide rail 14 is firmly combined with the accommodating part 21 through the fixing part 13.

[0070] After the strip-shaped oil-absorbing structure 10 reaches the designated position, it starts to adsorb the floating oil around it. After adsorption saturation, the winding device 30 and the regeneration device 40 are started through the control system. The extrusion of the strip-shaped oil-absorbing structure 10 is realized by adjusting the relative positions of the first extrusion roller 42 and the second extrusion roller 43. At the same time, the adsorbed oil substances are recovered and flow into the oil storage device 45 through the drain pipe 44 for storage. At this time, the winding device 30 is in the unwinding state. The oil absorption operation time of the strip-shaped oil-absorbing structure 10 on the water surface can be adjusted by controlling the speed at which the strip-shaped oil-absorbing structure 10 enters the regeneration device 40, so as to form a continuous operating state. When personnel participate in the oil removal process, the on-site start, stop, and process adjustment can also be realized through the regeneration control member 46.

[0071] During the entire oil removal process, the treatment situation can be observed based on the monitoring device 60, and the moving direction and speed of the hull can be comprehensively judged.

[0072] After the entire oil adsorption and removal operation is completed, adjust the winding device 30 to the reverse winding state, disconnect the connecting member 1 of the strip-shaped oil-absorbing structure 10 at the winding device 30 end, and ensure the activation of the regeneration device 40. The strip-shaped oil-absorbing structure 10 discharges the oil substances through the extrusion of the regeneration device 40, and then winds up on the winding device 30, completing the shutdown operation of the entire emergency oil removal treatment device.

[0073] The oil spill recovery device of this embodiment has the following advantages:

[0074] 1. In the oil absorption unit, the oil absorption matrix uses graphene-based modified sponge. Through the high-efficiency oil absorption performance and repeated utilization characteristics of the graphene-based modified sponge, combined with the regeneration device repeated multiple times, it can achieve unmanned continuous and efficient oil removal in the treatment of offshore oil spill accidents. In addition, the graphene-based modified sponge has good repeatability in use, less waste production, and is more environmentally friendly.

[0075] 2. The number of precise mechanical structures is small, and the equipment failure rate is low, which is beneficial for long-distance offshore operations.

[0076] 3. Through the position control of the connecting member on the strip-shaped oil-absorbing structure, oil removal operations in different areas can be realized, with strong flexibility, a large recovered oil pollution area in a single operation, and high overall equipment operation efficiency.

[0077] 4. On the strip-shaped oil-absorbing structure, a preset gap provided between the sliding part in the first connection unit and the sliding part in the second connection unit can achieve free swaying of the oil-absorbing structure within a certain range, and has a good buffering effect on the changes of sea waves and tides.

[0078] This specific embodiment is only an interpretation of the present application, and it does not limit the present application. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
