Description

Technical Field

[0001] This invention belongs to the field of marine vessel technology, specifically a marine pollution control structure and pollution control vessel. Background Technology

[0002] In the marine environment, aquatic debris, especially surface debris such as plastic bottles, discarded plastic bags, and abandoned fishing nets, drifts to the coast, affecting the living environment of marine life around the coastline. Sheet-like debris such as discarded plastic bags and fishing nets can directly cover the bodies of marine life and become tightly wrapped around them, making them difficult to remove. Rope-like debris can also become entangled on the bodies of marine life and, at the same time, on the propellers of ships, affecting their normal operation.

[0003] Human activity at the coast is becoming increasingly frequent, resulting in a surge of marine debris. Currently, the primary method for removing waste from the coastline is manual retrieval. This involves boats carrying personnel to the shoreline, who stand on the deck and use retrieval poles to lift floating debris. During this process, the debris can be dragged back into the sea by its own weight. In severe cases, individuals may become entangled in sheet-like debris, leading to drowning accidents. Furthermore, manual retrieval is time-consuming, labor-intensive, and inefficient, especially when dealing with heavy debris, it is difficult to retrieve from coral or rotten wood in the deeper waters. This results in poor cleanup effectiveness.

[0004] Therefore, the present invention provides a marine pollution control structure and a pollution control vessel. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A marine cleaning structure according to this invention includes a hull, with a salvage mechanism located at the front of the hull; the salvage mechanism includes a base, a connecting rod, a rotating shaft, a turntable, salvage rods, and a stop bar; the base is connected to the front deck of the hull, and one end of the connecting rod is connected to the end of the base. The other end of the connecting rod is hollow, and a drive motor and a gear set are located in the hollow part; the drive motor drives the rotating shaft to rotate through the gear set, and the rotating shaft rotates through the other end of the connecting rod. The end of the rotating shaft is fixed to the turntable, and multiple salvage rods are evenly connected to one end at the edge of the turntable. The other end is connected to a stop bar, with the angle between the central axis of the stop bar and the central axis of the salvage pole being less than 90 degrees. The hull slides along the coastline, and the drive motor drives the salvage pole to rotate around the central axis of the rotating shaft through a gear set, a rotating shaft, and a turntable. The salvage pole and the stop bar work together to hook the abandoned fishing nets around the coastline. As the hull moves forward, the salvage pole rotates, and the sheet-like and strip-like garbage are hooked one by one by each salvage pole and the stop bar. Compared with manual salvage by holding a long pole with hooks, this marine cleanup vessel is more time-saving, labor-saving, and efficient, while also reducing the risk of accidents caused by people standing on the deck of the hull being carried into the water by the garbage.

[0007] Preferably, multiple notches are provided at the edge of the turntable, and a connecting pin is rotatably connected in each notch. The connecting pin is vertically fixed to one end of the retrieval rod, and a rotating motor is rotatably connected to the end of the connecting pin. The rotating motor is fixed to the turntable.

[0008] The other end of the salvage rod has a rotating groove, which contains a reset motor and conical teeth. The end of the stop rod is also rotatably connected to the rotating groove via a connecting pin, which engages with the conical teeth at the output end of the reset motor. When a certain amount of garbage is entangled on the salvage rod, the hull is stopped, the drive motor is stopped, and the rotating motor drives the salvage rod to rotate via the connecting pin, causing the salvage rod to rotate to both sides of the hull at an angle greater than 90 degrees. At this point, the taut garbage on the adjacent salvage rods loosens. Then, the reset motor is controlled, which drives the stop rod to rotate via the conical teeth, making the central axis of the stop rod coaxial with the central axis of the salvage rod. At this point, the garbage entangled on the salvage rod can be easily removed, reducing the salvage rod's resistance to the seawater and allowing the salvage rod and stop rod to effectively salvage garbage from the sea surface again.

[0009] Preferably, a groove is formed on the end face of the base, and one end of a connecting rod is slidably connected in the groove. One end of the connecting rod is fixed to the piston rod end of the extension cylinder, and the extension cylinder is fixed to the base. Conveyor belts are provided on both sides of the base, with one end of the conveyor belt placed at the front of the hull deck and the other end placed in the middle area of ​​the hull deck. By extending the cylinder, the connecting rod extends out of the groove, allowing the retrieval rod to extend a greater distance. This is suitable for coral or gravel areas near the coast, preventing collisions between the hull and coral or gravel when the hull moves forward to retrieve fishing nets, and preventing the hull from running aground. After the retrieval rod rotates to both sides of the hull, the extension cylinder is controlled to extend the connecting rod into the groove, placing the retrieval rod above one end of the conveyor belt. Then, the debris on the retrieval rod is removed, and the conveyor belt transports the debris to the middle area of ​​the deck for easy disposal.

[0010] Preferably, each of the salvage rods has a cross-shaped guide groove. The salvage rod is hollow inside and contains a lead screw. One end of the salvage rod is equipped with a drive motor, the output end of which is fixed to one end of the lead screw. The other end of the lead screw is rotatably connected to the other end of the salvage rod. A push plate is connected to the lead screw and is slidably connected in the guide groove. After the salvage rod rotates to both sides of the hull, the drive motor pushes the push plate through the lead screw. The push plate pushes off the debris entangled on the salvage rod, saving time and effort, and preventing manual pulling, which could result in sharp objects entangled in the debris injuring people.

[0011] Preferably, a limiting groove is formed on the inner side wall of the guide groove, and a corrugated plate made of rubber is provided in the limiting groove. One end of the corrugated plate is fixed to the surface of the push plate, and the other end of the corrugated plate is fixed to the inner side of the other end of the retrieval rod along the limiting groove. The corrugated plate blocks the guide groove to prevent the corners of the garbage from extending into the interior of the retrieval rod and affecting the connection between the lead screw and the push plate, thus ensuring the stable sliding of the push plate.

[0012] Preferably, the diameter of one end of the retrieval rod is larger than the diameter of the other end, and the diameter of the other end of the retrieval rod is larger than the diameter of the end face of the stop rod. The difference in diameter makes it easier for the garbage wrapped around the retrieval rod to move towards the end of the retrieval rod, thus reducing the resistance of the wrapped garbage to the push plate, facilitating the removal of the garbage, and improving efficiency.

[0013] Preferably, a recess is formed on the lower deck of the base. The front side of the recess is rotatably connected to the front sidewall of the base, and a push cylinder is provided at the bottom of the rear side of the recess. The piston rod of the push cylinder is rotatably connected to the lower rear edge of the base, and the end of the push cylinder is fixed to the lower position of the recess. By using the push cylinder, the angle of the base on the upper deck of the hull is controlled, so that the salvage rod can salvage to a deeper sea surface. At the same time, in conjunction with the extension cylinder, the length of the connecting rod extending out of the slide is extended, so that the salvage rod can salvage garbage to a deeper sea area, making the salvage of coastal garbage more thorough.

[0014] Preferably, a winding mechanism is provided in the middle area of ​​the deck of the hull; the winding mechanism includes a winding motor, a winding rod and a pre-assembly box with a rotating door panel; the winding motor is fixed to the rear side wall of the pre-assembly box, and the output end of the winding motor is fixed to the winding rod inside the pre-assembly box.

[0015] Multiple vertical rods are fixed to both sides of the deck of the hull. The end diameter of the vertical rod is smaller than the end diameter of the winding rod. A baffle is provided on one side of the vertical rod. The baffle is arc-shaped and is vertically fixed to the deck of the hull. The garbage is transported to the middle area of ​​the deck by a conveyor belt. Then, the winding motor drives the winding rod to rotate and put the garbage into the pre-loading box. The garbage is tightly wound by the winding rod in the pre-loading box to reduce the space occupied by the garbage. After winding, the rotating door is opened and the garbage is removed. At this time, there is an opening in the middle of the wound garbage. The opening is inserted into the vertical rod and embedded between the vertical rod and the baffle, so that the garbage is stably placed on the vertical rod, realizing the compact stacking of garbage, reducing the space occupied by garbage on the deck after retrieval, allowing the deck to hold more garbage at one time, reducing the frequency of the hull returning to port, and improving the efficiency of garbage retrieval.

[0016] The pre-loading box is equipped with a V-shaped plate and a spring; the concave surface of the V-shaped plate is connected to the inner wall of the pre-loading box by the spring, and the upper ends of the two V-shaped plates are set in a wide-mouth shape; through the cooperation of the V-shaped plate and the spring, when the winding rod winds the garbage, the V-shaped plate squeezes the garbage, making the garbage winding tighter. At the same time, the inlet slope of the V-shaped plate prevents the garbage from falling and getting embedded in the spring, causing the winding rod to pull the garbage and affect the normal winding of the garbage.

[0017] The right angle of the first end face of the winding rod is greater than the diameter of the last end face. Multiple telescopic grooves are opened on the surface of the winding rod. A compression spring and a wedge block are provided in the telescopic groove. The wedge block is rotatably connected in the telescopic groove through the compression spring. The difference in diameter of the end faces of the winding rod makes it easy to remove the waste from the winding rod. At the same time, the wedge block prevents the waste from moving towards the smaller end face during the winding process, which would cause the waste to fail to be wound. The wedge block is rotatably connected in the telescopic groove through the compression spring. When the waste is removed, the wedge block squeezes the compression spring and rotates into the telescopic groove without affecting the removal of the waste.

[0018] Preferably, each of the retrieval rods has a strip groove on its side wall in the direction of rotation, the strip groove being formed along the length of the retrieval rod, and multiple return springs and blades are provided inside the strip groove; one end of the blade is rotatably connected to the inner side wall of the strip groove, the back side wall of the blade is connected to the strip groove through a return spring, and the cutting edge of the blade is positioned outside the groove opening; the blades cut off the debris on the two retrieval rods that are relatively close to each other on the two turntables, so as to facilitate the rotation of the retrieval rods.

[0019] A marine debris removal vessel includes a hull for mounting a marine debris removal structure as described in any one of the preceding claims.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The marine debris removal structure described in this invention uses a combination of retrieval rods and stop bars to hook onto sheet-like and strip-like debris around the coastline. As the hull moves forward, the retrieval rods rotate, and the debris is hooked one by one by each retrieval rod and stop bar. Compared to manual retrieval using long poles with hooks, this marine debris removal vessel is more time-saving, labor-saving, and efficient. It also reduces the risk of accidents caused by workers standing on the deck being pulled into the water by debris, and is more effective at removing strip-like or sheet-like marine debris.

[0022] 2. The marine debris removal structure of the present invention extends the connecting rod out of the slide groove by extending the cylinder, so that the retrieval rod can extend to a greater distance. It is suitable for coral or gravel areas where the hull is close to the coast, and prevents the hull from colliding with coral or gravel when the hull goes forward to retrieve debris, as well as preventing the hull from running aground.

[0023] 3. The marine debris removal structure described in this invention controls the angle of the base on the upper deck of the ship by using a push cylinder, allowing the retrieval rod to reach deeper waters. At the same time, in conjunction with an extension cylinder, the length of the connecting rod extending out of the slide groove is extended, enabling the retrieval rod to reach deeper waters and making the removal of debris from the coastline more thorough.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1:

[0038] Reference Figure 1-9 A marine debris removal structure includes a hull 1, with a salvage mechanism at the front end of the hull 1. The salvage mechanism includes a base 2, a connecting rod 3, a rotating shaft 4, a turntable 5, salvage rods 6, and a stop bar 7. The base 2 is connected to the front deck of the hull 1, and one end of the connecting rod 3 is connected to the end of the base 2. The other end of the connecting rod 3 is hollow, and a drive motor 8 and a gear set are installed in the hollow part. The drive motor 8 drives the rotating shaft 4 to rotate through the gear set. The rotating shaft 4 rotates through the other end of the connecting rod 3, and the turntable 5 is fixed to the end of the rotating shaft 4. Multiple salvage rods 6 are evenly connected to one end at the edge of the turntable 5, and the other end of the salvage rods 6 is connected to the stop bar 7. The angle between the central axis of the stop bar 7 and the central axis of the salvage rod 6 is less than 90 degrees. The hull 1 slides along the coastline, and the drive motor 8 drives the salvage rod 6 to rotate around the central axis of the rotating shaft 4 through the gear set, rotating shaft 4 and turntable 5. The salvage rod 6 cooperates with the stop bar 7 to hook the garbage around the coastline. As the hull 1 moves forward, the salvage rod 6 rotates, and the sheet-like and strip-like garbage is hooked one by one by each salvage rod 6 and stop bar 7. Compared with manual salvage by holding a long pole with hooks, the salvage by this marine cleaning vessel is more time-saving, labor-saving and efficient, and at the same time reduces the occurrence of dangerous accidents caused by people standing on the deck of the hull 1 being carried into the water by garbage.

[0039] Multiple notches are made at the edge of the turntable 5, and a connecting pin 9 is rotatably connected in each notch. The connecting pin 9 is vertically fixed to one end of the retrieval rod 6, and a rotating motor 10 is rotatably connected to the end of the connecting pin 9. The rotating motor 10 is fixed to the turntable 5.

[0040] The other end of the salvage rod 6 has a rotating groove 11, which contains a reset motor 12 and conical teeth. The end of the stop rod 7 is also rotatably connected to the rotating groove 11 via a connecting pin 9. The connecting pin 9 engages with the conical teeth at the output end of the reset motor 12 via the conical teeth. When a certain amount of garbage is wrapped around the salvage rod 6, the hull 1 is stopped from moving forward, and the drive motor 8 is stopped from rotating. The rotating motor 10 is controlled to drive the salvage rod 6 to rotate via the connecting pin 9, so that the salvage rod 6 rotates to both sides of the hull 1, and the rotation angle is greater than 90 degrees. At this time, the taut garbage on the adjacent salvage rods 6 is loosened. Then, the reset motor 12 is controlled, and the reset motor 12 drives the stop rod 7 to rotate via the conical teeth, so that the central axis of the stop rod 7 is coaxial with the central axis of the salvage rod 6. At this time, the garbage wrapped around the salvage rod 6 can be easily removed, which reduces the resistance of the salvage rod 6 to the seawater. This allows the salvage rod 6 and the stop rod 7 to effectively salvage the garbage on the sea surface again.

[0041] A groove 13 is formed on the end face of the base 2. One end of the connecting rod 3 is slidably connected within the groove 13. One end of the connecting rod 3 is fixed to the piston rod end of the extension cylinder 14, which is fixed to the base 2. Conveyor belts 15 are provided on both sides of the base 2. One end of the conveyor belt 15 is placed at the front end of the deck of the hull 1, and the other end is placed in the middle area of ​​the deck of the hull 1. Through the extension cylinder 14, the connecting rod 3 extends out of the groove 13, enabling the salvage rod 6 to extend to a greater distance. This system is suitable for areas with coral or gravel near the shore where the hull 1 is located, to prevent the hull 1 from colliding with the coral or gravel when it goes forward to retrieve the garbage, and to prevent the hull 1 from running aground. After the retrieval rod 6 rotates to both sides of the hull 1, the connecting rod 3 is extended into the chute 13 by controlling the extension cylinder 14. The retrieval rod 6 is placed above one end of the conveyor belt 15, and then the garbage on the retrieval rod 6 is removed. The conveyor belt 15 then transports the garbage to the middle area of ​​the deck for easy disposal.

[0042] Each of the salvage rods 6 has a cross-shaped guide groove 16. The salvage rod 6 is hollow inside and has a lead screw 17 inside. One end of the salvage rod 6 is equipped with a push motor 18. The output end of the push motor 18 is fixed to one end of the lead screw 17, and the other end of the lead screw 17 is rotatably connected to the other end of the salvage rod 6. A push plate 19 is connected to the lead screw 17 and is slidably connected in the guide groove 16. After the salvage rod 6 rotates to both sides of the hull 1, the push motor 18 pushes the push plate 19 through the lead screw 17. The push plate 19 pushes away the garbage wrapped around the salvage rod 6, saving time and effort, and preventing sharp objects wrapped in the garbage from injuring people when manually pulling it.

[0043] A limiting groove 20 is provided on the inner side wall of the guide groove 16. A corrugated plate 21 made of rubber is provided in the limiting groove 20. One end of the corrugated plate 21 is fixed to the surface of the push plate, and the other end of the corrugated plate 21 is fixed to the inner side of the other end of the retrieval rod 6 along the limiting groove 20. The corrugated plate 21 blocks the guide groove 16 to prevent the corners of the garbage from extending into the interior of the retrieval rod 6 and affecting the connection between the lead screw 17 and the push plate 19, thus ensuring the stable sliding of the push plate 19.

[0044] The diameter of one end of the retrieval rod 6 is larger than that of the other end, and the diameter of the other end of the retrieval rod 6 is larger than the diameter of the end face of the stop rod 7. The difference in diameter makes it easier for the garbage wrapped around the retrieval rod 6 to move towards the end of the retrieval rod 6, thus reducing the resistance of the wrapped garbage to the push plate 19, making it easier to remove the garbage and improving efficiency.

[0045] A recess 22 is provided on the lower deck of the base 2. The front side of the recess 22 is rotatably connected to the front side wall of the base 2. A push cylinder 23 is provided at the bottom rear side of the recess 22. The piston rod of the push cylinder 23 is rotatably connected to the lower rear edge of the base 2. The end of the push cylinder 23 is fixed to the lower position of the recess 22. By using the push cylinder 23, the angle of the base 2 on the upper deck of the hull 1 is controlled, so that the salvage rod 6 can salvage to a deeper sea surface. At the same time, in conjunction with the extension cylinder 14, the length of the connecting rod 3 extending out of the slide groove 13 is extended, so that the salvage rod 6 can salvage garbage to a deeper sea area, making the salvage of coastal garbage more thorough.

[0046] A winding mechanism is provided in the middle area of ​​the deck of the hull 1; the winding mechanism includes a winding motor 24, a winding rod 25 and a pre-assembly box 26 with a rotating door panel; the winding motor 24 is fixed to the rear side wall of the pre-assembly box 26, and the output end of the winding motor 24 is fixed to the winding rod 25 inside the pre-assembly box 26.

[0047] Multiple vertical rods 27 are fixed to both sides of the deck of the hull 1. The end diameter of the vertical rod 27 is smaller than the end diameter of the winding rod 25. A baffle 28 is provided on one side of the vertical rod 27. The baffle 28 is arc-shaped and is vertically fixed to the deck of the hull 1. The garbage is transported to the middle area of ​​the deck by the conveyor belt 15. Then, the winding motor 24 drives the winding rod 25 to rotate and put the garbage into the pre-loading box 26. The garbage is tightly wound by the winding rod 25 in the pre-loading box 26 to reduce the space occupied by the garbage. After winding, the rotating door is opened and the garbage is removed. At this time, there is an opening in the middle of the wound garbage. The opening is inserted into the vertical rod 27 and embedded between the vertical rod 27 and the baffle 28, so that the garbage is stably placed on the vertical rod 27, realizing the tight stacking of garbage, reducing the space occupied by garbage on the deck after retrieval, allowing more garbage to be carried on the deck at one time, reducing the return frequency of the hull 1, and improving the garbage retrieval efficiency.

[0048] The right angle of the first end face of the winding rod 25 is greater than the diameter of the last end face of the winding rod 25. Multiple telescopic grooves 29 are formed on the surface of the winding rod 25. A compression spring 30 and a wedge block 31 are provided in the telescopic groove 29. The wedge block 31 is rotatably connected to the telescopic groove 29 through the compression spring 30. The difference in diameter of the end face of the winding rod 25 makes it easy to remove the garbage from the winding rod 25. At the same time, the wedge block 31 prevents the garbage from moving towards the smaller end face during the winding process, which would cause the garbage to fail to be wound. The wedge block 31 is rotatably connected to the telescopic groove 29 through the compression spring 30. When the garbage is removed, the wedge block 31 squeezes the compression spring 30 and rotates into the telescopic groove 29 without affecting the removal of the garbage.

[0049] Each of the salvage rods 6 has a groove 34 on its side wall in the direction of rotation. The groove 34 is opened along the length of the salvage rod 6, and multiple return springs 35 and blades 36 are provided in the groove 34. One end of the blade 36 is rotatably connected to the inner side wall of the groove 34, and the back side wall of the blade 36 is connected to the groove 34 through the return springs 35. The cutting edge of the blade 36 is set outward from the opening of the groove 34. When the salvage rods 6 salvage garbage, the same garbage may get tangled on the two salvage rods 6 that are relatively close to each other on the two turntables. When the salvage rods 6 rotate to both sides of the hull 1, the garbage will hinder the rotation of the salvage rods 6. Therefore, by adding a return spring to the salvage rod 6, the return spring 35 is installed in the groove 34. The blade 36 is installed so that when the retrieval rod 6 rotates, it tears the garbage. At the same time, the garbage is cut and broken into two pieces by the blade 36, so that the two retrieval rods 6 can rotate smoothly to both sides of the hull 1. Meanwhile, the blade 36 is rotatably connected to the strip groove 34 through the return spring 35. When the push plate 19 moves along the retrieval rod 6, the blade 36 squeezes and compresses the strip groove 34. When the push plate 19 is reset, the blade 36 does not obstruct the push plate 19. Furthermore, when the push plate 19 moves, it can squeeze some garbage onto the blade, further squeezing and cutting the garbage, reducing the garbage's entanglement on the retrieval rod 6, and making it easier for the garbage to get off the retrieval rod 6.

[0050] A marine pollution control vessel includes a hull 1, which is used to install the marine pollution control structure described in any one of the above claims.

[0051] Example 2:

[0052] Reference Figure 10 Compared with Embodiment 1, as another embodiment of the present invention, the pre-loading box 26 is provided with a V-shaped plate 32 and a spring 33; the concave surface of the V-shaped plate 32 is connected to the inner wall of the pre-loading box 26 by the spring 33, and the upper ends of the two V-shaped plates 32 are set in a wide-mouth shape; through the cooperation of the V-shaped plate 32 and the spring 33, when the winding rod 25 winds the garbage, the V-shaped plate 32 squeezes the garbage, making the garbage winding tighter. At the same time, the inlet slope of the V-shaped plate 32 prevents the garbage from falling and embedding in the spring 33, causing the winding rod 25 to pull the garbage and affect the normal winding of the garbage.

[0053] Working principle: The drive motor 8 drives the rotating shaft 4 to rotate through the gear set. The rotating shaft 4 rotates through the other end of the connecting rod 3. The end of the rotating shaft 4 is fixed to the turntable 5. Multiple salvage rods 6 are evenly connected to one end at the edge of the turntable 5. The other end of the salvage rod 6 is connected to the stop bar 7. The angle between the central axis of the stop bar 7 and the central axis of the salvage rod 6 is less than 90 degrees. The hull 1 slides along the coastline. The drive motor 8 drives the salvage rod 6 to rotate around the central axis of the rotating shaft 4 through the gear set, rotating shaft 4 and turntable 5. The salvage rod 6 cooperates with the stop bar 7 to hook the garbage around the coastline. As the hull 1 moves forward, the salvage rod 6 rotates. The garbage is hooked one by one by each salvage rod 6 and stop bar 7. Compared with manual salvage by holding a long pole with hooks, the salvage by this marine cleaning vessel is more time-saving, labor-saving and efficient. At the same time, it reduces the risk of accidents caused by people standing on the deck of the hull 1 being carried into the water by garbage.

[0054] When a certain amount of garbage is entangled on the salvage rod 6, the hull 1 is stopped moving forward. At the same time, the drive motor 8 is stopped rotating, and the rotation motor 10 is controlled to drive the salvage rod 6 to rotate through the connecting pin 9. This causes the salvage rod 6 to rotate to both sides of the hull 1, and the rotation angle is greater than 90 degrees. At this time, the taut garbage on the adjacent salvage rods 6 is loosened. Then, the reset motor 12 is controlled. The reset motor 12 drives the stop bar 7 to rotate through the conical teeth, so that the central axis of the stop bar 7 is coaxial with the central axis of the salvage rod 6. At this time, the garbage entangled on the salvage rod 6 can be easily removed, which reduces the resistance of the salvage rod 6 to the seawater. This allows the salvage rod 6 and the stop bar 7 to effectively salvage the garbage on the sea surface again.

[0055] By extending the cylinder 14, the connecting rod 3 extends out of the chute 13, allowing the salvage rod 6 to extend to a greater distance. This is suitable for coral or gravel areas near the shore where the hull 1 is close to the coast, preventing the hull 1 from colliding with coral or gravel when it goes forward to salvage the garbage, and preventing the hull 1 from running aground. After the salvage rod 6 rotates to both sides of the hull 1, the connecting rod 3 is extended into the chute 13 by controlling the extension cylinder 14. The salvage rod 6 is placed above one end of the conveyor belt 15, and then the garbage on the salvage rod 6 is removed. The conveyor belt 15 then transports the garbage to the middle area of ​​the deck for easy disposal of waste.

[0056] After the salvage rod 6 rotates to both sides of the hull 1, the drive motor 18 pushes the push plate 19 through the lead screw 17. The push plate 19 pushes away the garbage wrapped around the salvage rod 6, saving time and effort, and preventing manual pulling, which may cause sharp objects wrapped in the garbage to injure people.

[0057] The difference in diameter makes it easier for the garbage wrapped around the retrieval rod 6 to move towards the end of the retrieval rod 6, thus reducing the resistance of the wrapped garbage to the push plate 19, making it easier to remove the garbage and improving efficiency.

[0058] By pushing the cylinder 23, the angle of the base 2 on the upper deck of the hull 1 is controlled, so that the salvage rod 6 can salvage to a deeper sea surface. At the same time, in conjunction with the extension cylinder 14, the length of the connecting rod 3 extending out of the slide groove 13 is extended, so that the salvage rod 6 can salvage garbage to a deeper sea area, making the salvage of coastal garbage more thorough.

[0059] The garbage is conveyed to the middle area of ​​the deck by the conveyor belt 15. Then, the winding motor 24 drives the winding rod 25 to rotate and put the garbage into the pre-loading box 26. The garbage is tightly wound by the winding rod 25 in the pre-loading box 26 to reduce the space occupied by the garbage. After winding, the rotating door is opened and the garbage is removed. At this time, there is an opening in the middle of the wound garbage. The opening is inserted into the vertical rod 27 and embedded between the vertical rod 27 and the baffle 28, so that the garbage is stably placed on the vertical rod 27, realizing the tight stacking of garbage, reducing the space occupied by the garbage on the deck after retrieval, allowing more garbage to be carried on the deck at one time, reducing the frequency of the ship 1 returning to port, and improving the efficiency of garbage retrieval.

[0060] The difference in diameter at the end faces of the winding rod 25 facilitates the removal of waste from the winding rod 25. At the same time, the wedge block 31 prevents the waste from concentrating and moving towards the smaller end face during the winding process, thus preventing the waste from failing to be wound. The wedge block 31 is rotatably connected to the telescopic groove 29 via the compression spring 30. When the fishing net is removed, the wedge block 31 squeezes the compression spring 30 and rotates into the telescopic groove 29 without affecting the removal of the waste.

[0061] The salvage mechanism installed on the hull 1, with the cooperation between the salvage rod 6 and the stop bar 7, is more effective at salvaging surface-shaped and strip-shaped garbage, such as discarded fishing nets, plastic bags, and towing ropes that have come off the fishing nets.
