Description

Technical Field

[0001] The present application relates to the field of oil spill and hazardous chemical recovery technology, and in particular to an explosion-proof marine hazardous chemical and oil spill recovery boat. Background Art

[0002] Currently, the primary technology for handling marine oil spills and hazardous chemicals relies on mechanical recovery devices, which are categorized into three types: disc, brush, and weir. The working principle of a rotary disc skimmer is that a disc made of oleophilic material rotates in an oil-water mixture. As the disc spins out, the absorbed oil is scraped into an oil sump by scrapers and then pumped to an oil storage device.

[0003] Generally, the oil skimmer is used in conjunction with a recovery boat. The oil skimmer is placed on top of the recovery boat, and the recovery boat is used to drive the oil skimmer to the oil spill site. After the staff assembles the pipes on the oil skimmer, they use the lifting mechanism to lower the oil skimmer to the sea surface. The oil skimmer works and collects the spilled oil into the oil spill storage device on the recovery boat.

[0004] Regarding the above-mentioned related technologies, the inventor believes that due to the influence of seasons, geographical location and weather, the wind and waves at sea may be very strong at certain times and places. Therefore, the operating equipment used at sea usually needs to have strong wind and wave resistance. In the above-mentioned technology, a lifting mechanism is used to lift the oil recovery unit onto the sea surface. The rope of the lifting mechanism is easily affected by strong winds and shakes. The oil recovery unit itself is easily affected by waves and shakes due to contact with the sea surface. The combination of the above two disturbances results in the oil recovery device in the above-mentioned technology not having strong wind and wave resistance and being easily affected by wind and waves at sea, thereby affecting the operating efficiency. Summary of the Invention

[0005] In order to enhance the wind and wave resistance of the oil recovery device and improve the operating efficiency, the present application provides an explosion-proof marine hazardous chemicals and oil spill recovery boat.

[0006] The explosion-proof marine hazardous chemicals and oil spill recovery boat provided in this application adopts the following technical solutions:

[0007] An explosion-proof marine hazardous chemical and oil spill recovery boat, comprising a recovery boat and an oil skimmer;

[0008] The bottom of the oil skimmer is fixed with a base, and a positioning column is vertically slidable on the base;

[0009] The recovery boat comprises:

[0010] The storage compartment has a communication port on its side wall. The storage compartment is used to place the oil skimmer. The storage compartment is provided with pads, which are arranged corresponding to the four corners of the oil skimmer.

[0011] Two slide rails are provided, which slide vertically along the side wall of the recovery boat. The bottom of the slide rail can slide upward to separate from the water surface, and the bottom of the slide rail can slide downward to enter the water surface;

[0012] Two connecting rods are provided, sliding along the length direction of the slide rail, being arranged horizontally, and extending away from the end of the slide rail toward each other;

[0013] A cargo fork is provided at one end of the two connecting rods close to each other and slides horizontally along the end of the connecting rod. The cargo fork can slide into the storage compartment. Both ends of the cargo fork are hinged with a stopper. When the stopper and the cargo fork are perpendicular to each other, the side wall of the stopper is in close contact with the side wall of the base.

[0014] The positioning plate is fixedly connected to the fork, is arranged horizontally and perpendicular to the length direction of the fork, and is provided with positioning holes on the positioning plate. The positioning columns correspond to and fit in the positioning holes one by one.

[0015] By adopting the above technical solution, when it is necessary to collect oil spills on the sea surface, first, the oil skimmer is stored in the recovery boat and is driven by the recovery boat to a designated position on the sea surface.

[0016] Then, the slide rail is made to slide vertically along the side wall of the recovery boat until the bottom of the slide rail slides into the water surface;

[0017] Make the connecting rod slide vertically along the length direction of the slide rail until the connecting rod moves to the bottom position of the connecting opening;

[0018] The fork is driven to slide into the accommodation chamber, and the top wall of the fork abuts against the bottom wall of the base;

[0019] Drive the block to rotate upward until it is perpendicular to the fork. At this point, the two blocks on the same fork will clamp the base together, thus preliminarily fixing the skimmer on the fork.

[0020] The positioning column is driven to slide vertically downward until the end of the positioning column is inserted into the positioning hole on the positioning plate, thereby further fixing the oil skimmer on the fork.

[0021] Then, the fork is slid horizontally to drive the oil skimmer to the outside of the storage chamber;

[0022] The connecting rod is slid vertically along the length direction of the slide rail to a suitable position, so that the oil skimmer enters the water surface and starts working to transport the collected spilled oil to the recovery boat.

[0023] When the oil skimmer finishes its work, the cargo fork drives the oil skimmer back to the storage tank, so that the oil skimmer can be driven to the next sea area for work by the recovery boat.

[0024] In summary, the use of technical features such as a cargo fork and a connecting rod to connect the oil skimmer to the recovery boat provides a secure connection between the cargo fork and the skimmer through two steps. Furthermore, these connecting mechanisms possess greater bending stiffness than the slings used in conventional hoisting mechanisms. This allows the skimmer to withstand greater wind and wave resistance during offshore operations, resulting in more stable operation and improved efficiency. Furthermore, this technical solution enables the skimmer to launch itself underwater, enhancing its automation and reducing the operator's workload.

[0025] In addition, the guide rail can move vertically along the height direction of the accommodation cabin. On the one hand, the bottom of the guide rail can be separated from the water surface during navigation, which is convenient for navigation and reduces the erosion of the bottom of the guide rail by seawater. On the other hand, it is convenient to adjust the distance of the guide rail entering the sea surface to adapt to various situations.

[0026] Optionally, a driving mechanism is provided in the base, and the driving mechanism includes:

[0027] The driving cylinder is vertically fixed in the base and is used to provide power for the vertical sliding of the positioning column;

[0028] The middle plate is arranged horizontally, with its length direction parallel to the horizontal sliding direction of the fork, and the driving cylinder is arranged in the middle of the middle plate;

[0029] The connecting plate corresponds to the positioning column one by one and is fixed to the end of the positioning column;

[0030] The guide column corresponds to the positioning column one by one, one end of which is fixed to the connecting plate and the other end of which is slidably connected to the base.

[0031] By adopting the above technical solution, the piston rod of the driving cylinder is extended, and the positioning column is driven to slide vertically through the intermediate plate and the connecting plate, so that the positioning column and the positioning plate can be plugged in or out;

[0032] At the same time, the guide column slides vertically along the base, thereby guiding the movement of each positioning column and making the movement process of the positioning column more stable.

[0033] Optionally, a snap-in groove is provided at the position of the base corresponding to the fork, the length direction of the snap-in groove is set parallel to the sliding direction of the fork, and the snap-in groove is adapted to the shape of the fork, and the positioning plate is connected to the bottom wall of the fork.

[0034] By adopting the above technical solution, the fork slides along the length direction of the clamping groove. On the one hand, the clamping groove serves as a movement guide for the fork, making the sliding process of the fork more stable, and by limiting the position of the fork, the position of the positioning plate is limited, thereby improving the corresponding accuracy between the positioning hole and the positioning column, and facilitating the subsequent insertion of the positioning column into the positioning hole; on the other hand, when the fork and the oil skimmer are relatively fixed, the fork is clamped with the base, further increasing the stability of the connection between the fork and the base.

[0035] In addition, the positioning plate abuts against the bottom surface of the base, increasing the contact area between the positioning plate and the base, thereby increasing the stability of the connection between the fork and the base.

[0036] Optionally, two clamping plates are provided, both of which are arranged parallel to the length direction of the fork and on the side of the pads facing away from each other. When the oil skimmer is placed on the pads, the two sides of the clamping plates that are close to each other abut against the side of the oil skimmer.

[0037] By adopting the above technical solution, when the oil skimmer is stored in the storage cabin, the space formed between the two clamping plates serves as a movement guide for the oil skimmer, so that the oil skimmer is placed in a fixed position in the storage cabin. On the one hand, it is convenient to connect the cargo fork and the oil skimmer when the oil skimmer is used again in the future. On the other hand, when the recovery boat drives the oil skimmer to move, the two clamping plates play a certain role in limiting the oil skimmer and preventing it from shifting.

[0038] Optional,

[0039] The oil skimmer further comprises two grooves, which are arranged on two opposite sides of the oil skimmer;

[0040] The recovery boat also includes:

[0041] A sliding plate is horizontally slidably connected to the top of the clamping plate, wherein the sliding direction of the sliding plate is perpendicular to the length direction of the clamping plate;

[0042] There are two pressing blocks, which move horizontally toward or away from each other along the top of the sliding plate;

[0043] The double-headed motor has two output shafts each fixed with a screw, and the two ends of the screw that are away from each other are respectively connected to the tightening blocks with threads.

[0044] By adopting the above technical solution, after the oil skimmer is placed on the footrest, the sliding plate is moved horizontally toward the oil skimmer; then, the double-headed motor drives the screw to rotate, so that the two clamping blocks move away from each other, until the two sides of the two clamping blocks are facing away from each other and are pressed against the inner wall of the groove.

[0045] The above solution further limits the oil skimmer, so that the oil skimmer is placed in a fixed position in the storage cabin. On the one hand, it can facilitate the connection between the cargo fork and the oil skimmer when the oil skimmer is used again in the future. On the other hand, when the recovery boat drives the oil skimmer to move, the two clamping plates play a certain role in limiting the oil skimmer to prevent the oil skimmer from shifting.

[0046] Optionally, the recovery boat further comprises a support rod, wherein the support rod is hinged to an end of the connecting rod, and the cargo fork is arranged parallel to the support rod and slides along the length direction of the support rod.

[0047] By adopting the above technical solution, when the fork is idle, the support rod is rotated to be parallel to the connecting rod, thereby facilitating the storage of the support rod, which not only facilitates navigation, but also prevents the fork from being opened during navigation and causing the fork to be deformed by resistance impact.

[0048] Optionally, the recovery boat further comprises a reinforcement assembly, the reinforcement assembly comprising two connecting rods, one end of the two connecting rods being hinged to each other, and the other ends of the two connecting rods being hinged to the connecting rod and the supporting rod respectively;

[0049] When the connecting rod and the supporting rod are rotated to be perpendicular to each other, the two connecting rods are arranged along the same straight line, and the connecting rod, the connecting rod and the supporting rod form a triangle.

[0050] By adopting the above technical solution, when the connecting rod and the support rod are rotated to be perpendicular to each other, the triangle formed by the connecting rod, the connecting rod and the support rod increases the stability of the connection between the connecting rod and the support rod, further increasing the stability of the oil collection device.

[0051] Optionally, the recovery boat is slidably connected with a sealing door at a position corresponding to the communication port, and the sealing door is used to shield the communication port.

[0052] By adopting the above technical solution, the sealed door protects the devices in the accommodation cabin, thereby preventing the external environment from interfering with the devices in the accommodation cabin due to excessive navigation speed.

[0053] Optionally, the recovery boat includes a bidirectional drive assembly, the bidirectional drive assembly including:

[0054] The guide rail is oval in shape, and the slide rail and the sealing door are respectively slidably connected on two sides of the guide rail that are parallel to each other;

[0055] Ratchets are respectively arranged at both ends of the guide rail and are rotatably connected to the side wall of the recovery boat;

[0056] The chain is tensioned on the ratchet and rotates along the length direction of the guide rail. The slide rail and the sealing door are fixed to two points on the chain respectively.

[0057] By adopting this technical solution, the ratchet rotates, driving the chain along the length of the guide rail. This allows the sealing door to slide upward while the rail slides downward simultaneously. This solution allows the sealing door and rail to move synchronously in opposite directions. When the sealing door detaches from the connection port, the rail moves toward the water surface; when the sealing door reaches the connection port, the rail moves away from the water surface. This further improves work efficiency, enhances coordination between various links, and conserves drive.

[0058] Optionally, the recovery boat includes an oil spill and hazardous chemical storage compartment, which is correspondingly arranged below the holding compartment and has an oil spill and hazardous chemical storage tank inside;

[0059] The oil spill and hazardous chemicals storage compartment is connected to the accommodation compartment, and an inspection ladder is provided at the connection point.

[0060] By adopting the above technical solution, it is convenient for staff to go to the oil spill and hazardous chemical storage tank and the containing tank through the maintenance ladder to inspect the internal devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The following is combined with Figure 1-10 This application is described in further detail.

[0073] The present application discloses an explosion-proof marine hazardous chemicals and oil spill recovery boat. Figure 1 , an explosion-proof marine hazardous chemical and oil spill recovery boat includes a recovery boat 1 and an oil recovery machine 2. The oil recovery machine 2 is used in conjunction with the recovery boat 1, which can not only be used for the recovery of oil spills on the sea surface, but can also be widely used in coastal areas, harbors and other places where hazardous chemicals need to be recovered. It is suitable for the recovery of hazardous chemicals such as styrene, xylene, and butyl acrylate. This explosion-proof marine hazardous chemical and oil spill recovery boat is a water hazardous chemical disposal and environmental protection work boat with a towing function that sails and operates along the coast. It is driven by an explosion-proof diesel engine and propelled by dual full-rotating propellers in the rear engine room. It is mainly used for the containment, cleaning and recovery of hazardous chemicals on the sea surface. By adding an explosion-proof device to the diesel engine, the explosion-proof requirements of the recovery boat 1 are met, and the safety of equipment and personnel is guaranteed.

[0074] Reference Figure 2 From top to bottom, the recovery boat 1 comprises a holding compartment 11 and an oil spill and hazardous chemical storage compartment 12. These compartments are vertically connected at both ends, and each is equipped with a maintenance ladder 13. One end of the maintenance ladder 13 extends out of the top of the recovery boat 1, allowing personnel to access both compartments and inspect the equipment within. The equipment located near the maintenance ladder 13 in both the holding compartment 11 and the oil spill and hazardous chemical storage compartment 12 is identical; only the equipment on one side will be described here as an example.

[0075] Reference Figure 2 An oil spill and hazardous chemical storage tank 121 is provided in the oil spill and hazardous chemical storage cabin 12. The top of the oil spill and hazardous chemical storage tank 121 is connected and communicated with a telescopic pipe, and the end of the telescopic pipe is passed through the interior of the accommodating cabin 11.

[0076] Reference Figure 3 The oil skimmer 2 is housed within a storage tank 11, which houses a hydraulic power station 111 and an oil pump 112. A telescopic tube extending from the oil spill and hazardous chemical storage tank 121 is connected to the oil pump 112, and the other end of the oil pump 112 is connected to the oil skimmer 2 via the telescopic tube. When the oil skimmer 2 floats on the sea surface, the oil, powered by the oil pump 112, flows along the telescopic tube and is stored in the oil spill and hazardous chemical storage tank 121. The hydraulic power station 111 is connected to the oil skimmer 2 via the telescopic tube, providing power for the operation of the oil skimmer 2.

[0077] The hydraulic power station 111 is powered by an explosion-proof diesel engine from the main engine, which drives a hydraulic oil pump. This converts diesel power into hydraulic power to drive the oil recovery unit 2. Using an explosion-proof diesel engine as the power source ensures the safety of the entire recovery unit, preventing hazards such as mechanical failure or explosion.

[0078] Reference Figure 4 The oil skimmer 2 is preferably a rotary disc type skimmer 2. This type of skimmer 2 is known technology and will only be briefly described here. A disc 21 is rotatably connected to the skimmer 2. Disc 21 is made of an oleophilic material, and a scraper 22 is positioned near the disc 21. An oil collection trough 23 is also located in the center of the skimmer 2. The end of the telescopic tube connected to the spilled oil and hazardous chemical storage tank 121 is connected to and communicates with the oil collection trough 23. When the skimmer 2 is in operation, the disc 21 rotates, absorbing oil from the oil-water mixture. The absorbed oil is then scraped by the scraper 22 into the oil collection trough 23 and pumped into the spilled oil and hazardous chemical storage tank 121.

[0079] Reference Figure 3 , pads 113 are fixedly provided at the four corners of the bottom wall of the storage compartment 11 corresponding to the oil skimmer 2 to support the oil skimmer 2.

[0080] Reference Figure 4 The bottom of the oil skimmer 2 is fixed with a base 3, and the two opposite sides of the oil skimmer 2 are recessed inward to form a rectangular groove 4. Two pads 113 close to the same groove 4 are set as a group. The pads 113 in the same group are fixed with the same clamping plate 41. The clamping plate 41 and the structure connected thereto are the same. Figure 4Here, only one of the clip plates 41 is used as an example for description. The clip plate 41 is disposed on the side away from the two sets of feet 113. When the oil skimmer 2 is placed on the feet 113, the sides of the two clip plates 41 that are closer to each other abut against the side of the oil skimmer 2. The space formed between the two clip plates 41 not only guides the oil skimmer 2 when it is placed on the feet 113, so that the oil skimmer 2 is placed in a fixed position within the storage chamber 11, but also limits the oil skimmer 2 when the recovery boat 1 drives the oil skimmer 2, preventing it from shifting.

[0081] Reference Figure 4 A sliding plate 42 slides horizontally on the top of the clamping plate 41. The length of the sliding plate 42 is slightly smaller than the length of the groove 4. The sliding plate 42 moves in a direction perpendicular to the length direction of the clamping plate 41. A tightening block 43 is slidably connected to both ends of the sliding plate 42. The tightening block 43 moves toward or away from each other along the length direction of the sliding plate 42. A double-headed motor 44 is fixed at the middle position of the top of the sliding plate 42. The bottom wall of the double-headed motor 44 is fixed to the bottom wall of the groove 4. The output shaft ends of the two ends of the double-headed motor 44 are fixed with screws 45. The two screws 45 extend from one end of the double-headed motor 44 to the two ends of the tightening block 43 that are separated from each other, and the screws 45 are threadedly connected to the tightening block 43 at the positions that are separated from each other. According to the above technical solution, after the sliding plates 42 on both sides of the oil skimmer 2 are driven into the groove 4, the double-headed motor 44 rotates, driving the two screws 45 to rotate. The rotation of the screws 45 drives the two abutting blocks 43 to move away from each other, so that the opposing sides of the two abutting blocks 43 abut against the two vertical walls of the groove 4, further limiting the position of the oil skimmer 2. In addition, each abutting block 43 is provided with a clearance groove 46 at the position where the two abutting blocks 43 are close to each other. When the two abutting blocks 43 are close to each other, the clearance groove 46 is used to accommodate the double-headed motor 44.

[0082] Reference Figure 5 A connecting port 5 is provided on the side wall of the storage chamber 11, and a sealing door 51 is vertically slidably provided at the corresponding connecting port 5 of the storage chamber 11. Dust covers 52 are fixed on the opposite sides of the side wall of the storage chamber 11 corresponding to the sealing door 51, and a two-way drive component 53 is provided in the dust cover 52.

[0083] Reference Figure 6The two-way drive assembly includes a guide rail 531, which is configured to be elliptical and fixedly connected to the dust cover 52. A ratchet 532 is rotatably connected inside the dust cover 52, and the ratchet 532 is respectively arranged at both ends of the guide rail 531. A chain 533 is tensioned outside the ratchet 532, and the chain 533 is rotatably connected along the inner wall of the guide rail 531. The two ends of the sealing door 51 close to the dust cover 52 are respectively slidably connected to the guide rails 531 in the two two-way drive assemblies 53, and are respectively fixed to the chains 533. A sliding rail 54 is provided on the side of the two dust covers 52 that face away from each other. The sliding rail 54 is configured to be long and vertically arranged. The sliding rail 54 is slidably connected to the side of the guide rail 531 that is parallel to the connection point of the sealing door 51, and the sliding rail 54 is fixed to the chain 533.

[0084] The ratchet 532 rotates, driving the chain 533 to rotate along the length of the guide rail 531. This causes the sliding rail 54 to slide downward in tandem with the upward movement of the sealing door 51. This arrangement allows the sealing door 51 and the sliding rail 54 to move synchronously in opposite directions. When the sealing door 51 is disengaged from the communication port 5, the sliding rail 54 moves toward the water surface. When the sealing door 51 reaches the communication port 5, the sliding rail 54 moves away from the water surface. This further improves work efficiency, enhances coordination between various links, and conserves drive capacity.

[0085] Reference Figure 5 The slide rail 54 is vertically slidably connected to a connecting rod 6, which is horizontally arranged and extends toward each other from one end of the connecting rod 6 away from the slide rail 54. A support rod 61 is hinged to one end of the connecting rod 6 that is close to each other.

[0086] Reference Figure 7 A reinforcement assembly is provided between the support rod 61 and the connecting rod 6. Each reinforcement assembly includes two connecting rods 62, which are hinged at their connection. The ends of the two connecting rods 62, facing away from each other, are hinged to the bottom walls of the connecting rod 6 and support rod 61, respectively. When the connecting rod 6 and support rod 61 are rotated until they are perpendicular to each other, the two connecting rods 62 are arranged along the same straight line, and the connecting rods 62, connecting rod 6, and support rod 61 form a triangle, which increases the stability of the connection between the connecting rod 6 and support rod 61 and further enhances the stability of the oil recovery device.

[0087] Reference Figure 8 When the oil skimmer 2 is not needed, the support rod 61 is rotated to be parallel to the connecting rod 6, so that the support rod 61 can be stored. On the one hand, it is convenient for sailing, and on the other hand, it avoids the support rod 61 from being stretched out during sailing, causing the support rod 61 to be deformed by resistance impact.

[0088] Reference Figure 7 、 8A fork 7 is slidably connected along the length of the support rod 61. The fork 7 is configured in a rod shape, and the length of the fork 7 is set parallel to the length of the support rod 61. Both ends of the fork 7 are hinged with a stopper 71. The stopper 71 can be rotated along the hinge point until the stopper 71 is parallel to the fork 7 or rotated until the stopper 71 is perpendicular to the fork 7. A plurality of positioning plates 72 are fixed to the bottom of the fork 7. The positioning plates 72 are evenly distributed along the length of the fork 7. The length of the positioning plates 72 is horizontal and perpendicular to the length of the fork 7. A positioning hole 73 is formed on the end of the positioning plate 72 away from the fork 7.

[0089] Reference Figure 5 When the fork 7 is needed to take the oil skimmer 2 out of the storage compartment 11, the support rod 61 is rotated around the hinge point to a position perpendicular to the connecting rod 6. During the rotation, one end of the support rod extends into the storage compartment 11 below the corresponding oil skimmer 2, making it easier for the fork 7 to move horizontally along the length of the support rod 61 to the bottom of the oil skimmer 2, thereby fixing the oil skimmer 2 and the fork 7.

[0090] Reference Figure 9 The base 3 has a snap-in slot 31 at the point where it contacts the fork 7. The length of the slot 31 is parallel to the sliding direction of the fork 7, and the shape of the slot 31 matches that of the fork 7. As the fork 7 slides along the length of the support rod 61, it slides along the length of the slot 31 until one of the stops 71 extends outside the slot 31. The stop 71 is then rotated to be perpendicular to the fork 7. At this point, the two stops 71 on the same fork 7 jointly clamp the base 3, preliminarily securing the oil skimmer 2 to the fork 7. As the fork 7 slides along the length of the slot 31, the slot 31 guides the fork 7, stabilizing its movement and limiting the position of the positioning plate 72. Furthermore, when the fork 7 is fixed relative to the oil skimmer 2, the fork 7 engages the base 3, further enhancing the stability of the connection between the fork 7 and the base 3.

[0091] Reference Figure 9 、 Figure 10A positioning column 32 is slidably connected to each positioning hole 73 on the base 3. A driving mechanism is provided inside the base 3. The driving mechanism includes a driving cylinder 33. The driving cylinder 33 is vertically arranged. The cylinder body of the driving cylinder 33 is fixed inside the base 3. The piston rod of the driving cylinder 33 extends vertically downward, and an intermediate plate 34 is fixed to the end of the piston rod. The piston rod is fixed to the middle position of the top of the intermediate plate 34. The intermediate plate 34 is horizontally arranged and is arranged in the shape of a long strip. The length direction of the intermediate plate 34 is parallel to the horizontal sliding direction of the fork 7. Connecting plates 35 are fixed on both sides of the intermediate plate 34 at the positions corresponding to the positioning columns 32. The connecting plates 35 and the intermediate plates 34 are arranged perpendicular to each other. A guide column 36 is fixed at the bottom of the connecting plate 35 at the positions corresponding to the positioning holes 73. It corresponds one-to-one with the positioning columns 32, one end is fixed to the connecting plate 35, and the other end is slidably connected to the base 3. The piston rod of the driving cylinder 33 is extended, driving the positioning column 32 to slide vertically through the intermediate plate 34 and the connecting plate 35, so as to facilitate the insertion or disengagement of the positioning column 32 and the positioning plate 72; and at the same time, the guide column 36 slides vertically along the base 3, thereby guiding the movement of each positioning column 32, making the movement process of the positioning column 32 more stable.

[0092] The implementation principle of an explosion-proof marine hazardous chemical and oil spill recovery boat in the embodiment of the present application is as follows:

[0093] When it is necessary to collect spilled oil or hazardous chemicals on the sea surface, first, the oil skimmer 2 is stored in the recovery boat 1 and is driven by the recovery boat 1 to a designated position on the sea surface.

[0094] Then, the ratchet 532 rotates, driving the chain 533 to rotate along the length direction of the guide rail 531, so that when the sealing door 51 slides upward, the slide rail 54 slides downward synchronously, and slides to the bottom of the slide rail 54 into the water surface. At this time, the sealing door 51 is separated from the connecting port 5.

[0095] Make the connecting rod 6 slide vertically along the length direction of the slide rail 54 until the connecting rod 6 moves to the bottom position of the connecting port 5; make the support rod 61 rotate to be perpendicular to the connecting rod 6, and the triangle formed by the connecting rod 62, the connecting rod 6, and the support rod 61 increases the stability of the connection between the connecting rod 6 and the support rod 61.

[0096] The fork 7 is driven to slide into the accommodation chamber 11, and the fork 7 slides along the length direction of the engaging groove 31 until the stopper 71 extends to the outside of the engaging groove; the stopper 71 is driven to rotate upward until the stopper 71 is perpendicular to the fork 7. At this time, the two stops 71 on the same fork 7 jointly clamp the base 3, thereby preliminarily fixing the oil skimmer 2 on the fork 7.

[0097] The positioning column 32 is driven by the driving cylinder 33 to slide vertically downward until the end of the positioning column 32 is inserted into the positioning hole 73 on the positioning plate 72, thereby further fixing the oil skimmer 2 on the fork 7.

[0098] The double-headed motor 44 rotates, driving the pressing blocks 43 to move toward each other; the sliding plate 42 slides to disengage from the groove 4, and then the fork 7 slides horizontally, driving the oil skimmer 2 to the outside of the storage chamber 11.

[0099] The connecting rod 6 is slid vertically along the length direction of the slide rail 54 to a suitable position, so that the oil skimmer 2 enters the water surface and is put into operation to transport the collected spilled oil to the recovery boat 1.

[0100] When the oil skimmer 2 finishes its work, the cargo fork 7 drives the oil skimmer 2 back to the interior of the storage chamber 11 , thereby facilitating the recovery boat 1 to drive the oil skimmer 2 to the next sea area for operation.

[0101] In summary, the use of technical features such as the cargo fork 7 and connecting rod 6 to connect the oil skimmer 2 to the recovery boat 1 provides a secure connection between the cargo fork 7 and the skimmer 2 through two steps. Furthermore, these connecting mechanisms possess greater bending stiffness than the slings used in conventional hoisting mechanisms. This allows the skimmer 2 to withstand greater wind and wave resistance during offshore operations, resulting in more stable operation and improved efficiency. Furthermore, this technical solution enables the skimmer 2 to self-launch, enhancing its automation and reducing the operator's workload.

[0102] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
