Description

Technical Field

[0001] This invention relates to the field of marine cage recycling technology, specifically to an automatic dock for a surface garbage cleaning vessel. Background Technology

[0002] With the rapid development of my country's economy and the country's higher requirements for the protection of the aquatic environment, it is necessary to clean up the garbage on the water surface in order to maintain the aesthetics of the river environment and the cleanliness of the water. Otherwise, it will not only cause blockage of the river, but also have a devastating impact on the original ecosystem of the river. However, when cleaning up garbage in rivers and lakes, the manual retrieval method is not only costly and inefficient, but also poses a risk of falling into the water. To solve this problem, Chinese patent application No. 202122174404.0, published on February 11, 2022, discloses an unmanned boat garbage cleaning and recycling system, including: a garbage collection unit and a garbage recycling unit; wherein the garbage collection unit specifically includes: a boat. The system comprises a ship hull, a waste collection frame, a waste collection net, and an outer collection net. The waste collection frame is installed on the hull, and the waste collection net is movably installed inside the waste collection frame for temporary waste storage. The outer collection net extends outside the hull to guide waste into the waste collection net. The waste recycling unit includes a recycling base station, a lifting platform, and a horizontal telescopic hook lock. The lifting platform and the horizontal telescopic hook lock are both installed on the recycling base station. The horizontal telescopic hook lock is used to pull the waste collection net onto the lifting platform for further processing. By setting up the waste recycling unit, the system can automatically recycle and transport river waste collected by the waste collection unit, completing the final step of waste recycling and processing, saving manpower and resources, and accelerating the efficiency of cleanup. However, when the system collects garbage from the garbage collection net, after the hull collects the garbage on the water surface, it uses a horizontal telescopic hook to pull the garbage collection net into the collection base station and then pulls the garbage collection net onto the lifting platform. Thus, the hull is still on the water surface when the garbage collection net is being pulled. The wind and waves and the different water levels directly affect the stability of the hull. At the same time, it cannot automatically replace the garbage collection net box. The garbage collection net box needs to be pulled back to the collection base station and then the new garbage collection net box needs to be manually installed on the hull. The operation is slow, which affects the efficiency of the operation. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic dock for a surface garbage cleaning vessel, which can ensure that the vessel can stably leave the water and can replace garbage nets, and is simple and efficient to operate.

[0004] To achieve the above objectives, an automatic dock for a surface garbage collection vessel is provided for the recovery and replacement of net cages on the hull. The dock includes a lifting device and a recovery device. The lifting device includes a fixed support frame, a guide plate, a support bracket for the hull, and a limiting spring for positioning. The recovery device includes a net cage storage ring and a push-pull device. The net cage storage ring includes an outer ring and an inner ring, with the inner ring disposed within a cavity of the storage ring. One end of the push-pull device is fixedly connected to the outer ring, and the other end is disposed within the inner ring and moves along the axial and vertical directions of the inner ring. The outer ring is fitted onto the inner ring, and the inner ring and outer ring are in a rolling connection. Two or more sets of sliding joints are provided on the inner wall of the inner ring. Each set of slots includes two opposing guide rails. One end of the inner ring is provided with a driven gear, and the outer side of the outer ring is provided with a first drive motor. The first drive motor is rotatably connected to the drive gear. The drive gear passes through a second through hole on the outer ring and meshes with the driven gear to rotate. One end of the fixed bracket is fixedly connected to the outer side of the outer ring. One side of the fixed bracket is provided with a first slot and a second slot that match the guide slot plate. The first slot is provided with a gear and a transmission chain. The transmission chain is engaged with one end of the guide slot plate. The boat support is located inside the guide slot plate. The limiting spring is located inside the guide slot plate and close to one end of the net cage storage ring.

[0005] The above configuration involves a drive wheel rotatably connected to the output of the first drive motor. A second through hole is provided on the outer ring, allowing the drive wheel to pass through and mesh with the driven wheel at one end of the inner ring. This causes the drive wheel to rotate after the first drive motor starts, which in turn rotates the inner ring within the cavity of the net cage storage ring. Simultaneously, a guide rail is provided on the inner ring, allowing the net cages in the hull to be retrieved onto the guide rail. Then, by rotating the inner ring, other net cages are rotated to their corresponding positions on the hull, completing the net cage replacement. The operation is simple, quick, and efficient, eliminating the need to wait for all the garbage in the net cages to be collected before continuing work; different net cages can be directly replaced, effectively improving the hull's operational efficiency. The net cage storage ring is fixedly connected to the fixed legs, and... One side of the fixed bracket is equipped with a first and a second slide groove that match the guide trough plate. A gear and a transmission chain are installed in the first slide groove, engaging with the guide trough plate. The gear drives the transmission chain, allowing the guide trough plate to move along the length of the slide groove. A limiting spring and a boat support are positioned inside the guide trough plate, with the limiting spring positioned near the end closest to the net cage storage ring. This ensures that after the boat enters the guide trough, the boat support holds the bottom of the boat, the limiting spring shields the front of the boat, and the guide trough plates on both sides shield the sides of the boat. Driven by the gear and transmission chain, the boat can stably leave the water, avoiding the influence of waves and varying water levels, thus ensuring the stability of the boat during net cage retrieval.

[0006] Furthermore, the inner ring is provided with a first through hole and a guide rail for placing the net cage. A connecting shaft is provided in the first through hole, and the roller passes through the connecting shaft and rolls along the inner side of the outer ring in the first through hole. The gear includes a first gear and a second gear. The second gear is rotatably connected to the output shaft of the second drive motor. The second drive motor is installed on the side of the fixed foot near the lifting device. There are two or more fixed feet.

[0007] The above configuration achieves a rolling connection between the inner and outer rings by setting rollers on the inner ring, reducing the friction between the inner and outer rings. The structure is simple and can drive the gears and transmission chain to rotate via a drive motor.

[0008] Furthermore, the guide groove plates are symmetrically arranged, and each guide groove plate includes an extension, a connecting portion, and a sliding portion. One end of the extension is fixedly connected to one end of the connecting portion, and the other end of the extension extends outward from the guide groove plate. The other end of the connecting portion is fixedly connected to one end of the sliding portion, and the other end of the sliding portion extends into the second sliding groove and forms a sliding connection with the second sliding groove.

[0009] The above configuration, by extending the guide trough plate outward to form an outward V-shape, facilitates the alignment of the hull before it enters the guide trough. By setting the other end of the sliding part in the second sliding groove to form a sliding connection, the horizontal direction of the guide trough plate can be limited, so that the guide trough plate can only slide in the vertical direction.

[0010] Furthermore, the other end of the sliding part is connected to one end of the connecting block, and the other end of the connecting block is provided with a protrusion that matches the transmission chain, and the protrusion engages with the transmission chain.

[0011] The above configuration involves connecting the connecting block to the sliding part of the guide plate, with a protrusion on the connecting block that engages with the transmission chain. This allows the drive motor to drive the gears, which in turn rotates the transmission chain. As a result, the connecting block and the transmission chain rotate simultaneously, enabling the transmission chain to drive the guide plate and the hull to slide along the vertical direction of the fixed support. This ensures that the guide plate protects the hull and the support structure, allowing the hull to stably leave the water and preventing the hull from shifting or deviating due to the influence of waves.

[0012] Furthermore, one end of the boat support is fixedly connected to the inner side of the connecting part, and the other end of the boat support extends downward into the guide groove.

[0013] The above configuration, by fixing one end of the boat support to the inner side of the connecting part of the guide trough plate and extending the other end of the boat support into the guide trough, ensures that the boat support can support the bottom of the boat after the boat enters the guide trough, thus providing support for the boat when it leaves the water surface with the guide trough plate.

[0014] Furthermore, one end of the guide rail is fixedly connected to the inner side of the inner ring, and the other end of the guide rail extends in the opposite direction. A stepped portion is provided on one side of the guide rail, and the stepped portions of the two opposite guide rails form a groove with the inner sidewall of the inner ring that matches the protrusions on both sides of the bottom of the cage.

[0015] The above design facilitates the replacement of net cages by guiding them to slide along the grooves into the net cage storage ring.

[0016] Furthermore, the push-pull device includes a connecting plate, a lifting screw, a lifting screw motor, a belt drive structure, and a buckle. The connecting plate is located at one end of the outer ring near the driven wheel. Both ends of the connecting plate are fixedly connected to the outer ring. A lifting screw motor and a lifting screw are located on the side of the connecting plate near the outer ring. The lifting screw motor is connected to the lifting screw. One end of the lifting screw is connected to a connecting rod. A belt drive structure is located on the other end of the connecting rod. The buckle is located on the belt drive structure and moves with the belt.

[0017] The above setup uses a lifting screw motor to drive the lifting screw to rotate, which in turn moves the connecting rod to adjust the height by moving it vertically. The belt drive structure on the connecting rod drives the buckle to move axially along the inner ring.

[0018] Furthermore, the belt drive structure includes a first pulley, a second pulley, and a belt disposed on one side of the connecting rod. The second pulley is rotatably connected to the output end of the third drive motor, and the first pulley and the second pulley are driven by the belt.

[0019] The above setup uses a third drive motor to drive the second pulley to rotate, thereby driving the belt drive.

[0020] Furthermore, a fixing block is provided at the bottom of the belt, one end of the fixing block is fixedly connected to the belt, and the buckle is provided at the other end of the fixing block.

[0021] The above setup includes a buckle for securing the net cage. A belt drive moves the buckle and the net cage horizontally, allowing the net cage to slide along the guide rail into the net cage storage ring.

[0022] Furthermore, a sensor is provided on the outer side of the connecting part.

[0023] The above setup allows the sensors to determine the water level, thus facilitating the assessment of the ship's contact with the water surface. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 10 As shown, an automatic dock for a surface garbage cleaning vessel is used to recycle and replace the net cages 1 on the hull 2. It includes a lifting device and a recycling device. The lifting device includes a fixed bracket 3, a guide trough plate 4, a boat support 5 for supporting the hull, and a limiting spring 6 for limiting. In this embodiment, the limiting spring 6 includes two elastic pieces arranged between the guide trough plates 4 and laterally arranged in the groove formed by the guide trough plates 4. The recycling device includes a net cage storage ring and a push-pull device.

[0036] like Figure 1 and Figure 2 As shown, the cage storage ring includes an outer ring 7 and an inner ring 8, which can be viewed together. Figure 3As shown, the inner ring 8 is set inside the cavity of the net cage storage ring. The inner ring 8 has eight first through holes 223 and two or more sets of sliding grooves for placing the net cage 1. Each sliding groove includes two oppositely arranged guide rails 222, and the first through hole 223 is set between the two symmetrical guide rails 222. One end of the guide rail 222 is fixedly connected to the inner side of the inner ring 8, and the other end of the guide rail 222 extends in the opposite direction. One side of the guide rail 222 is provided with a step portion 2221. The step portions of each pair of opposite guide rails 222 are oppositely arranged. The step portions of the two oppositely arranged guide rails 222 form a sliding groove with the bottom of the net cage 1, which facilitates guiding the net cage 1 to slide along the groove into the net cage storage ring. A connecting shaft 224 is provided in the first through hole 223. The roller 225 passes through the connecting shaft 224 in the first through hole 223 and can roll along the inner side of the outer ring 7. One end of the inner ring 8 is provided with a driven wheel 221, which is fixedly connected to one end of the inner ring 8.

[0037] See Figure 4 As shown, a second through hole 211 is provided at one end of the outer ring 7 opposite to the driven wheel 221. A first drive motor 212 is provided on the outer side of the outer ring 7. The first drive motor 212 is rotatably connected to the drive wheel 213. The drive wheel 213 passes through the second through hole 211 on the outer ring 7 and meshes with the driven wheel 221 to rotate. After the first drive motor 212 is started, it drives the drive wheel 213 to rotate, which in turn drives the inner ring 8 to rotate in the cavity of the net cage storage ring. The rotation of the inner ring 8 rotates the net cage 1 to the position corresponding to the hull 2.

[0038] like Figure 10 and Figure 5The push-pull device includes a connecting plate 9, a lifting screw 10, a lifting screw motor (not shown in the figure), a belt drive structure, and a buckle 18. One end of the fixed bracket 3 is fixedly connected to the outer side of the outer ring 7. The connecting plate 9 is located at one end of the outer ring 7 near the driven wheel 221. Both ends of the connecting plate 9 are fixedly connected to the outer ring 7. The lifting screw 10 and the lifting screw motor are located on the side of the connecting plate 9 near the outer ring 7. In this embodiment, a mounting groove for accommodating the lifting screw is provided on the side of the connecting plate 9 near the outer ring 7. The lifting screw 10 is connected to one end of the connecting rod 91 at the top of the mounting slot, allowing the connecting rod 91 to move vertically to adjust its height. A belt drive structure is mounted on the connecting rod 91, including a first pulley 13, a second pulley 14, and a belt 15 on one side of the connecting rod 91. The second pulley 14 is rotatably connected to the output end of the third drive motor 16, and the first pulley 13 and the second pulley 14 are driven by the belt 15. In this embodiment, the other end of the connecting rod 91... A receiving groove is provided to accommodate the belt drive structure. The third drive motor and the first pulley are fixed in the receiving groove. After the third drive motor 16 is started, it can drive the second pulley 14 to rotate, thereby driving the belt 15 to drive. A fixing block 17 is provided at the bottom of the belt 15. One end of the fixing block 17 is fixedly connected to the belt 15, and the other end of the fixing block 17 is provided with a buckle 18 for engaging the wire mesh box 1. The buckle 18 includes a push plate 182 and a hook plate 181. One end of the push plate 182 and the hook plate 181 are fixed to the fixing block 17. At the other end, the push plate 182 is positioned close to the second pulley 14, with the other end of the push plate 182 positioned downwards and away from the second pulley 14. The other end of the hook plate 181 is positioned downwards and inwards. The belt 15 drives the buckle 18 and the net box 1 to move horizontally, so that the net box 1 slides along the guide rail 222 into the net box storage ring. During retrieval, the hook plate 181 hooks the net box inside the hull. During replacement, the push plate 182 pushes the net box in the inner ring, thus completing the retrieval and replacement of the net box 1.

[0039] The third drive motor drives the buckle 18 to push the net box 1 along the guide rail 222 out of the net box storage ring, thereby completing the replacement of the net box 1. There is no need to wait for all the garbage in the garbage net box to be recycled before continuing the operation. Instead, different net boxes can be replaced directly. The operation is simple, quick and efficient, which effectively improves the operation efficiency of the ship.

[0040] In this embodiment, two fixed feet 3 are provided, and guide slot plates 4 are symmetrically arranged on the fixed feet 3. A first slide groove 21 and a second slide groove 22 are provided on one side of the fixed feet 3. The first slide groove 21 and the second slide groove 22 extend along the height direction of the fixed feet 3, and one side of the first slide groove 21 is connected to one side of the second slide groove 22. The first slide groove 21 is provided with a first gear 26, a second gear 36 and a transmission chain 37. The second gear 36 is rotatably connected to the output shaft of the second drive motor 28.

[0041] In this embodiment, a sensor (not shown in the figure) is provided on the outside of the connecting part 32, which can facilitate the determination of the contact between the hull 2 ​​and the water surface.

[0042] like Figure 1 As shown, the guide trough plate 4 includes an extension 31, a connecting part 32, and a sliding part 33. One end of the extension 31 is fixedly connected to one end of the connecting part 32, and the other end of the extension 31 extends outward from the guide trough plate 4, forming an outward V-shape, which helps guide the hull 2 ​​to straighten its hull before it enters the guide trough. The other end of the connecting part 32 is fixedly connected to one end of the sliding part 33. One end of the boat support 34 is fixedly connected to the inner side of the connecting part 32, and the other end of the boat support 34 extends into the guide trough, ensuring that the boat support 34 can support the bottom of the hull 2 ​​after it enters the guide trough, thus providing support for the hull 2. In addition, the other end of the sliding part 33 extends into the second sliding groove 22 and forms a sliding connection with the second sliding groove 22. The sliding part 33 limits the horizontal movement of the guide plate 4, allowing it to slide only vertically. Simultaneously, the other end of the sliding part 33 connects to one end of the connecting block 34, and the transmission chain engages with the protrusion 35 at the other end of the connecting block 34. This drives the second gear 36 via the second drive motor 28, which in turn rotates the transmission chain 37. This causes the connecting block 34 and the transmission chain 37 to rotate simultaneously, enabling the transmission chain 37 to drive the guide plate 4 and the hull 2 ​​to slide vertically along the fixed support. This ensures that the guide plate 4, carrying the hull 2 ​​and the support 4, supports the hull 2 ​​and keeps it stably off the water surface, avoiding the influence of waves and varying water levels, thus ensuring the stability of the hull during the recycling of the garbage bins.

[0043] In this embodiment, a net cage for recycling is provided at the bottom of the hull 2. The structure of the hull 2 ​​can be referred to the structure of the hull in Chinese patent application No. 20221021743.3.

[0044] A method for operating an automated dock for surface debris cleaning vessels includes the following steps: (1) After the net cage is full of garbage, the hull enters the automated dock along the guide trough plate; (2) Start the lifting device, and the boat lift will lift the hull together to the front of the recovery device and connect with the guide rail of the recovery device; (3) Turn on the belt drive device, and the buckle pulls the net box along the guide rail into the net box storage ring; (4) After the net cage slides into the corresponding position of the net cage storage ring, the lifting screw drives the connecting rod and belt transmission device to rise, and the first drive motor is started to make the drive wheel drive the transmission wheel to rotate, so that the inner ring slides along the inner side of the outer ring and rotates the net cages in other slots to the position corresponding to the hull. (5) The lifting screw descends while driving the connecting rod and belt drive device to descend, so that the buckle engages with the net box. Then the belt drive device drives the buckle to push the net box along the guide rail out of the net box storage ring, so that the net box is combined with the hull and the net box replacement is completed. (6) The lifting device lowers the hull and net cage to the water surface, and the hull leaves the cabin along the guide trough.
