[0002] There are already many treatment technologies for marine oil spills, mainly focusing on physical adsorption, chemical absorption and oxidative combustion, biological degradation, etc. Among them, physical absorption and chemical absorption are the commonly used methods with the least environmental pollution. The adsorption method can achieve efficient oil-water separation of oil substances from seawater, thereby removing polluted oil from the sea. There are various existing adsorption equipment, but they all have problems such as small effective adsorption range, poor continuous operation ability, and great influence by tidal waves to a certain extent, resulting in low efficiency of oil spill recovery operations. At the same time, the uncertainty of the viscosity of the oil spill affects the adsorption efficiency, resulting in low efficiency of a single operation. Summary of the invention

[0046] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Example

[0048] See attached Figure 1-12 , wherein throughout all of these views, the same reference numerals denote corresponding components, and an embodiment of the oil absorption structure shown in this embodiment can be seen in Figure 1-4 9-12, according to the embodiment of the present invention, an embodiment of the water surface oil spill recovery device is constructed as shown in FIG. Figure 5-8 It should be understood that the oil absorption structure and the surface oil spill recovery device according to the present application can be used in all application scenarios where oil spill treatment and oil recovery are required in water environments such as rivers, lakes and seas.

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

[0050] Continue to see Figure 1-2 The oil absorption unit 2 includes a container 21 with a mesh structure and an oil absorption matrix 22 wrapped in the container 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 container 21 of this embodiment is a large-aperture and high-strength mesh structure. In the container with a mesh structure, it can be designed as a round hole, square hole or other irregular shape with an average pore size of 1-10mm, and the tear strength is greater than 50MPa. The oil absorption matrix is ​​fixed in the container with a mesh structure to ensure that the overall oil absorption structure has good toughness and strength, and at the same time has better oil absorption performance.

[0051] See also Figure 2 The connecting member 1 includes a first connecting unit 11 and a second connecting unit 12 arranged opposite to each other, see Figure 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. Figure 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. Figure 3-4 As shown, two positioning parts 16 are arranged between the two sliding parts 15, and a predetermined 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 predetermined 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 arranged alternately, and the sliding parts 15 in the first connecting unit 11 are arranged in the positioning of the second connecting unit 12, and the sliding parts 15 in the second connecting unit 12 are arranged in the positioning of the first connecting unit 11. At this time, by adjusting the position of the positioning portion 16 to adjust the size of the clamping position in the first connection unit 11 and the clamping position in the second connection unit 12, a preset gap is provided between the sliding portion 15 in the adjacent first connection unit 11 and the sliding portion 15 in the second connection unit 12. Due to the existence of the gap, the oil absorption structure 10 can be controlled to achieve a certain angle of bending. On the one hand, the single oil removal range of the oil absorption structure 10 can be controlled, and on the other hand, the oil absorption structure 10 can be freely shaken within a certain range, which has a good buffering effect on the changes of waves and tides. The sliding portion 15 in the adjacent first connection unit 11 and the sliding portion 15 in the second connection unit 12 are both tooth-shaped structures with arc-shaped ends. The arc-shaped ends can avoid wear when the sliding portion 15 contacts during bending, and at the same time, the oil absorption units can be bent more smoothly.

[0052] See also Figure 3There is a preset gap between the sliding part 15 in the adjacent first connecting unit 11 and the sliding part 15 in the second connecting unit 12, and the size of the gap is greater than 0 and less than the height of the adjacent sliding part in the direction perpendicular to the slide rail, that is, from 0 (not included) to the height dimension of the overlapping of the adjacent sliding parts. The specific principle that the existence of the gap can enable the oil absorption structure 10 to achieve a certain angle of bending is described as follows:

[0053] Assume the limit 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 ( Fig. 9 ), there is no bending margin between two adjacent oil suction units 2, so the angle between the two oil suction units 2 is 180°, which is a straight line, so more oil suction 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 fixing part can be achieved, and the inclination angle is α ( Fig.11 ), so that the bending angle θ between the oil suction units 2 is 180°-α, thus <180°( Fig.12 ), the radius of the oil removal circle formed by the belt-shaped oil absorption structure is expressed as:

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

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

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

[0058] like Figure 5 As shown, the surface oil spill recovery device of this embodiment includes: a hull 20, an oil suction structure 10, a traction device 50, a reeling 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 suction structure 10, the traction device 50, the reeling 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 equipment 60 is installed on both sides of the hull. The monitoring equipment 60 of this embodiment is a commercially available 360° high-definition monitoring camera, which can remotely transmit and present the entire situation of the deoiling area.

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

[0061] When emergency oil removal is required in waters, the hull 20 sails to a designated location and stops, and then the clamping member (such as a claw / hook, etc.) in the towing device 50 clamps the container 21 in any oil suction unit 2 of the oil suction structure 10, and then the towing device 50 enters the water from the bow. The drone 51 of the towing device 50 is an automatic cruise ship (drone), which travels according to the command route to arrange the oil suction belt at the designated location.

[0062] During the arrangement of the strip-shaped oil-absorbing structure 10, the traction device 50 and the hull 20 do not move simultaneously;

[0063] When all the strip-shaped oil-absorbing structures 10 are placed at the designated positions, the drone 51 returns to the tail of the hull 20 under command, and then connects the oil-absorbing structure 10 at the head held by the clamping member with the oil-absorbing structure at the tail of the hull 20 that is not placed in the water area (the connection method is that the first connection unit is connected to the second connection unit), and the strip-shaped oil-absorbing structure is enclosed to form an oil removal ring. Then the traction device 50 travels to the bow and returns to the warehouse.

[0064] See also 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, driving the winding shaft 32 to realize forward and reverse rotation, thereby realizing the release and winding operations of the belt-shaped oil absorption structure 10 along the length direction.

[0065] In this embodiment, during the feeding process of the reeling device 30, the belt-shaped oil absorption structure gradually winds around the reeling shaft 32 as the reeling shaft 32 rotates. A limiter is set on the reeling shaft 32 according to the width of the belt-shaped oil absorption structure 10 to prevent the reeling from deviating. A leveler is set just above the reeling device 30. The leveler is composed of a soft steel rope and a leveling roller. At the initial stage of reeling, the soft steel rope is in a free extension state. As the reeling progresses, the leveling roller is gradually lifted by the belt-shaped oil absorption structure 10. The soft steel rope is in a free and unstressed state. The leveling roller is a hollow metal rod. It relies on gravity to level the irregular belt-shaped oil absorption structure 10 to prevent the belt-shaped oil absorption structure 10 from winding and knotting.

[0066] See also Figure 7 The regeneration device 40 includes a regeneration frame 41, a first squeezing roller 42, a second squeezing roller 43, an oil drain pipe 44 and a regeneration control member 46. The first squeezing roller 42 and the second squeezing roller 43 are sequentially distributed along the height direction of the regeneration frame 41, see Figure 7 , the first squeezing roller 42 is located above the second squeezing roller 43, and the roller surfaces of the first squeezing roller 42 and the second squeezing roller 43 are arranged to face each other, the first squeezing roller 42 and the second squeezing roller 43 are respectively movably arranged on the regeneration frame 41, and a preset squeezing space is arranged between the first squeezing roller 42 and the second squeezing roller 43. The first squeezing roller 42 and the second squeezing roller 43 can obtain different squeezing spaces by adjusting their positions, and then apply different pressures to the strip-shaped oil absorption structure 10, so as to recover the oil substances absorbed by the oil absorption structure 10 from the water environment such as the sea. The regeneration control parts 45 are all arranged on the regeneration frame, and the inlet of the oil discharge pipe 44 is correspondingly arranged at the squeezing point where the oil absorption structure 10 is squeezed by the first squeezing roller 42 and the second squeezing roller 43 ( Figure 7 The oil storage device 45 is provided at the outlet of the oil discharge pipe 44 for storing oil substances, and the extruded oil substances are discharged to the oil storage device 45 through the oil discharge pipe 44 for collection. Since two rollers arranged opposite to each other are used to realize rolling extrusion, and the control device is used to control the start and stop of the rolling of the rollers, which are 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 component 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 reeling device 30 and the regeneration device 40, so as to 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 as follows:

[0069] When an oil spill occurs, the ship 20 is equipped with a belt-shaped oil absorption structure 10, a traction device 50, a reeling device 30, a regeneration device 40, an oil storage device 45 and a monitoring device 60. The monitoring device 60 transmits all image data to the control system on land, and the ship 20 is navigated to the designated oil removal area through remote control. Then the traction device 50 is deployed, and the oil content of the surrounding sea area is detected by the oil content detection device 52 and the data is remotely transmitted to the control system on land to determine whether to perform the oil removal operation. If the oil content does not meet the treatment requirements, the hull 20 is sailed to the next oil removal area. If it is determined to meet the treatment requirements, the clamping member (not shown) of the traction device 50 clamps the oil absorption structure 10 to be towed, and at the same time, the belt-shaped oil absorption structure 10 is connected to the reeling shaft 32 on the reeling device 30. The belt-shaped oil absorption structure 10 is towed and dragged to the target position according to the set program through the automatic cruising of the traction device 50. Then the traction device 50 returns to standby from the other side of the hull 20, and connects the belt-shaped oil absorption structure 10 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. The oil absorption structure 10 passes through the extrusion space to form a ring (such as Figure 8 At this time, the belt-shaped oil absorption structure 10 floats the oil absorption unit 2 on the water surface at a certain bending angle through the internal connecting member 1. The size of the bending angle is mainly controlled by the gap between the sliding parts 15, and the gap is achieved by the positioning part 16 fixing the sliding part 15 at different positions of the slide rail 14, and the slide rail 14 is firmly combined with the receiving part 21 through the fixing part 13.

[0070] After the belt-shaped oil absorption structure 10 reaches the designated position, it starts to absorb the surrounding floating oil. After the absorption is saturated, the reeling device 30 and the regeneration device 40 are turned on through the control system. The extrusion of the belt-shaped oil absorption structure 10 is achieved by adjusting the relative positions of the first extrusion roller 42 and the second extrusion roller 43, and the recovered adsorbed oil substances flow into the oil storage device 45 through the oil discharge pipe 44 for storage. At this time, the reeling device 30 is in the discharge state. The oil absorption operation time of the belt-shaped oil absorption structure 10 on the water surface can be adjusted by controlling the speed at which the belt-shaped oil absorption structure 10 enters the regeneration device 40, thereby forming a continuous operation state. When there are people involved in the oil removal process, the regeneration control component 46 can also be used to realize on-site start, stop and process adjustment.

[0071] During the entire deoiling process, the processing situation can be observed based on the monitoring device 60 to comprehensively judge the moving direction and speed of the hull.

[0072] After all the adsorption and oil removal operations are completed, the reeling device 30 is adjusted to the reverse reeling state, and the connector 1 of the belt-shaped oil absorption structure 10 at the end of the reeling device 30 is disconnected, while ensuring the opening of the regeneration device 40. The belt-shaped oil absorption structure 10 discharges the oil substances through the squeezing of the regeneration device 40, and then reeled on the reeling device 30, completing the closing operation of the entire emergency oil removal treatment device.

[0073] The surface 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 efficient oil absorption performance and reusability of graphene-based modified sponge, combined with multiple regeneration equipment, unmanned continuous and efficient oil removal can be achieved in the treatment of offshore oil spill accidents. In addition, the graphene-based modified sponge has good reusability, less waste production, and is more environmentally friendly.

[0075] 2. The number of precision mechanical structures is small and the equipment failure rate is low, which is conducive to long-distance operations at sea.

[0076] 3. By controlling the position of the connecting parts on the belt-shaped oil suction structure, oil removal operations can be achieved in different areas, with strong flexibility, a large oil recovery area in a single operation, and high overall equipment operation efficiency.

[0077] 4. On the strip-shaped oil absorption structure, a preset gap between the sliding part in the first connecting unit and the sliding part in the second connecting unit can realize the free shaking of the oil absorption structure within a certain range, which has a good buffering effect on waves and tidal changes.
