Description

A method for rotating and recovering surface net cages Technical Field

[0001] This invention relates to the field of marine cage recycling technology, specifically to a method for rotating and recycling surface cages. Background Technology

[0002] With the rapid development of my country's economy, the country has higher requirements for the protection of the water environment. In order to maintain the beauty of the river environment and the cleanliness of the water, it is necessary to clean up the garbage on the water surface. At present, most of the garbage cleaning in rivers and lakes is done manually, which is not only costly and inefficient, but also often puts workers at risk of falling into the water.

[0003] To address this issue, a patent document with Chinese patent application number 202210869270.0 and publication date of September 23, 2022, discloses an adsorption-type unmanned vessel for sorting and cleaning surface garbage, which belongs to the field of surface garbage cleaning technology. It includes a hull; pontoons mounted on both sides of the hull; smart cameras located on each side of the hull to collect information on surface debris; a detachable water-passing gate installed at the front of the hull, with a filter screen on the surface and a retractable baffle plate on the inside, with a filter plate installed inside the baffle plate; a propeller installed at the rear of the hull, working with a rudder to control the hull's navigation; a water-absorbing turbine installed inside the baffle plate to absorb surface debris; a waste collection bin inside the hull for sorting and collecting waste; a waste dumping hopper mounted on a magnetically controlled rail via a support cylinder to collect waste from inside the hull and dump it into the waste collection bin; a battery pack and solar panels installed on the top of the hull; a water pump installed on the outside of the hull; and a smart control cabinet installed on the hull for route planning, controlling the hull's movement, and sorting and collecting waste, especially for collecting slippery items like bottles and cans. However, after the unmanned vessel completes the surface garbage cleanup, it needs to dock at the shore and then manually prepare multiple garbage cages, pull one cage out of the water, and then install the next cage to replace the cage and recycle the garbage inside. This is inconvenient to operate and results in low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a method for rotating and recycling surface net cages, which can automatically replace the waste.

[0005] The garbage bins are reliable and easy to operate.

[0006] To achieve the above objectives, a method for rotating and recovering net cages on a water surface is provided. This method utilizes a surface recovery device to recover and replace net cages on a vessel. The surface recovery device includes a net cage, a net cage storage ring, a fixing bracket, and a pushing device. The net cage storage ring comprises an outer ring and an inner ring. The inner ring is disposed within a cavity of the storage ring and has a first through hole and a groove for placing the net cage. A connecting shaft is provided within the first through hole, and a roller passes through the connecting shaft and rolls along the inner side of the outer ring within the first through hole. One end of the fixing bracket is fixed to the outer side of the outer ring. The outer ring is fixedly connected to the outer ring, and a first drive motor is provided on the outer side of the outer ring. A driven wheel is provided at one end of the inner ring. The first drive motor is rotatably connected to the drive wheel. The drive wheel passes through a second through hole on the outer ring and meshes with the driven wheel to rotate. The outer ring is fitted on the inner ring and the inner ring is tumbled to the outer ring. Two or more sets of sliding grooves are provided on the inner sidewall of the inner ring. Each set of sliding grooves includes two oppositely arranged guide rails. One end of the pushing device is fixedly connected to the outer ring, and the other end of the pushing device is located inside the inner ring and moves along the axial direction and height direction of the inner ring.

[0007] Includes the following steps:

[0008] (1) At least one set of slides in two or more sets of slides in the net cage storage ring is not placed with net cages, and the other sets of slides are set with net cages to be replaced. After the net cages on the hull are connected to the slides in the net cage storage ring that are not placed with net cages, the pushing device is turned on so that the pushing device is engaged with the net cages on the hull.

[0009] (2) The pushing device pulls the net cage on the hull and slides it completely into the corresponding position in the net cage storage circle. The pushing device stops working and moves a distance away from the net cage storage circle, so that the pushing device is disconnected from the net cage in the net cage storage circle.

[0010] (3) The pushing device is raised and the first drive motor is started so that the driving wheel drives the driven wheel to rotate. The roller on the inner ring is connected to the inner wall of the outer ring to achieve the inner ring sliding along the inner side of the outer ring, and the net cages in other chutes are rotated to the position corresponding to the hull.

[0011] (4) The pushing device descends to the position corresponding to the hull, so that the buckle engages with the net cage, and then the pushing device pushes the net cage along the chute out of the net cage storage ring and into the hull.

[0012] The above method involves first aligning the chute without net cages within the net cage storage ring with the hull, then using a pushing device to pull the net cages from the hull into the storage ring for retrieval. Next, the inner ring is rotated to align the net cages on other rails with the hull, and then the pushing device pushes them onto the hull to replace the net cages. This achieves automated net cage replacement and retrieval. After pulling the net cages into the storage ring, the pushing device is moved a distance away from the storage ring to disengage and rise, allowing other net cages in the inner ring to enter their corresponding positions on the hull. This operation is simple and reliable.

[0013] Simultaneously, by placing the inner ring within the cavity of the net cage storage ring and providing a first through hole on the inner ring, a connecting shaft is installed within the first through hole, allowing the roller to pass through the connecting shaft and roll along the inner side of the outer ring. Furthermore, the drive wheel is rotatably connected to the output end of the first drive motor, and a second through hole is provided on the outer ring, allowing the drive wheel to pass through the second through hole and mesh with the driven wheel at one end of the inner ring. Thus, when the first drive motor is started, it drives the drive wheel to rotate, thereby causing the inner ring to rotate within the cavity of the net cage storage ring, enabling the desired net cage to be rotated onto the boat. The corresponding positions on the hull are for use by the hull, and a chute is set on the inner ring so that the net cages in the hull can be retrieved into the chute on the inner ring. Then, by rotating the inner ring, other net cages are rotated to the corresponding positions on the hull to complete the replacement and selection of net cages, improving the utilization of space. There is no need for manual preparation of multiple net cages and selection one by one. After the selected net cages are rotated to the corresponding positions on the hull, they are pushed into the hull by a pushing device, or pulled into the net cage storage ring from the hull. The operation is simple and effectively improves the replacement efficiency of garbage net cages.

[0014] Furthermore, there are two or more first through holes.

[0015] The above settings can reduce friction between the inner and outer rings, allowing the inner ring to roll better along the inner side of the outer ring.

[0016] 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 side wall of the inner ring that matches the protrusions on both sides of the bottom of the cage.

[0017] The above design facilitates the replacement of net cages by guiding them to slide along the grooves into the net cage storage ring.

[0018] Furthermore, the pushing device includes a connecting plate, a lifting screw, a lifting screw motor, a connecting rod, a belt drive structure, and a buckle. The connecting plate is provided at one end of the outer ring near the driven wheel. The two ends of the connecting plate are respectively fixedly connected to the outer ring. The lifting screw and the lifting screw motor are provided on one side of the connecting plate near the outer ring. The lifting screw is connected to one end of the connecting rod, and the other end of the connecting rod is connected to the belt drive structure. The buckle is fixed to the belt drive structure.

[0019] Step (2) includes the belt conveyor working and driving the buckle to pull the net cage on the hull completely into the corresponding position in the net cage storage ring. The pushing device stops working and moves a distance away from the net cage storage ring, so that the buckle is disengaged from the net cage in the net cage storage ring.

[0020] Step (3) includes driving the lifting screw motor to rotate the lifting screw, thereby causing the connecting rod to move upward, starting the first drive motor so that the driving wheel drives the driven wheel to rotate, and the roller on the inner ring rolls with the inner wall of the outer ring to achieve the inner ring sliding along the inner side of the outer ring, and rotating the net cages in other troughs to the position corresponding to the hull.

[0021] Step (4) includes the lifting screw motor driving the lifting screw to rotate, thereby driving the connecting rod to move downward to the position corresponding to the hull, so that the buckle engages with the net box, and then the belt drive structure pushes the net box along the slide groove out of the net box storage ring and into the hull.

[0022] The above settings facilitate vertical movement of the lifting screw and connecting rod for height adjustment, while the belt drive structure enables horizontal movement of the pushing device, ensuring reliable operation.

[0023] 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.

[0024] Step (4) also includes the following: after the net cage slides out of the net cage storage ring along the guide rail, the belt drives the buckle to continue moving a certain distance, so that the buckle disengages from the net cage, and the net cage replacement is completed.

[0025] The above setup uses a second drive motor to drive a second pulley, which in turn drives the belt drive.

[0026] 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 other end of the fixing block is provided with a buckle;

[0027] Step (1) specifically includes the second drive motor driving the pulley and belt, which in turn drives the buckle fixed on the belt to move horizontally toward the net box, so that the buckle collides with the net box to complete the engagement.

[0028] 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.

[0029] Furthermore, the buckle includes a push plate and a hook plate, one end of the push plate and the hook plate are fixed to the other end of the fixing block, and the push plate is disposed close to the second pulley, the other end of the push plate is disposed downward and away from the second pulley, and the other end of the hook plate is disposed downward and towards the inner ring.

[0030] In step (1), “activating the pushing device so that the pushing device engages with the net cage” includes the operation of the belt drive structure so that the buckle moves to the corresponding position on the hull and the hook plate engages with the net cage on the hull.

[0031] In step (4), “the pushing device descends to the position corresponding to the hull so that the buckle engages with the net cage” includes the operation of the lifting screw motor driving the lifting screw to rotate, thereby driving the connecting rod to move downward to the corresponding position on the hull, and the pushing plate engaging with the net cage.

[0032] The above setup allows for the retrieval and replacement of the net cages by hooking them onto the hull using a hook plate and by pushing the net cages within the inner ring using a push plate. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] As shown in Figures 1 to 8, a method for rotating and recycling surface net cages is provided. The surface net cage recycling device is used to replace and recycle the surface net cages. The surface net cage recycling device includes a net cage 1, a net cage storage ring and a fixing bracket 3, and a pushing device. The net cage storage ring includes an outer ring 7 and an inner ring 8, and two fixing brackets 3 are provided.

[0044] The cage storage ring includes an outer ring 7 and an inner ring 8, as shown in Figure 3. The inner ring 8 is located inside the cavity of the cage storage ring. The inner ring 8 has eight first through holes 223 and two or more sets of sliding grooves for placing the cage 1. Each sliding groove includes two oppositely arranged guide rails 222, and the first through holes 223 are located 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... The stepped portion 2221 is provided with the stepped portions of each pair of opposite guide rails 222 being arranged opposite each other. The stepped portions of the two opposite guide rails 222 form a sliding groove with the bottom of the net box 1, which facilitates the guidance of the net box 1 to slide along the groove into the net box 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. A driven wheel 221 is provided at one end of the inner ring 8. The driven wheel 221 is fixedly connected to one end of the inner ring 8.

[0045] Referring to Figure 4, 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.

[0046] As shown in Figures 2, 3, and 6, one end of the fixed bracket 3 is fixedly connected to the outer side of the outer ring 7. The pushing device includes a connecting plate 9, a lifting screw 10, a lifting screw motor (not shown in the figure), a connecting block, a belt drive structure, and a buckle. 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 the 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, the connecting plate 9 is located near the outer ring 7. A mounting groove for accommodating a lifting screw is provided on one side of the connecting rod 91. The lifting screw motor is located at the top of the mounting groove. The lifting screw 10 is connected to one end of the connecting rod 91, allowing the connecting rod 91 to move vertically to adjust different heights. A belt drive structure is provided on the connecting rod 91. The belt drive structure includes a first pulley 13, a second pulley 14, and a belt 15 located 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. The first pulley 13 and the second pulley 14 are connected by the belt 15. In this embodiment, the other end of the connecting rod 91 is provided with a receiving groove for accommodating 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 net 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 connected to the net box 1. The other end of the fixed block 17 is fixed, and the push plate 182 is set close to the second pulley 14. The other end of the push plate 182 is set downward and away from the second pulley 14. The other end of the hook plate 181 is set downward and inward. The buckle 18 and the net box 1 are driven to move horizontally through the belt 15, so that the net box 1 slides into the net box storage ring along the guide rail 222. When it is retrieved, the hook plate 181 hooks the net box in the hull. When it is replaced, the push plate 182 pushes the net box in the inner ring, thereby completing the retrieval and replacement of the net box 1.

[0047] 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.

[0048] As shown in Figure 9, a method for rotating and recovering surface net cages includes the following steps:

[0049] (1) In the net cage storage ring, at least one set of the two or more sets of slots is not filled with net cages, and the other sets of slots are filled with net cages to be replaced. After the net cage on the hull is connected to the slot of the net cage storage ring that is not filled with net cages, the belt drive device is turned on. The second drive motor drives the pulley and belt, which in turn drives the buckle fixed on the belt to move horizontally towards the net cage, so that the hook plate on the buckle collides with the net cage on the hull to complete the engagement.

[0050] (2) The belt drives the buckle to pull the net box from the second pulley to the first pulley. The net box slides completely into the corresponding position in the net box storage ring, and the belt drive structure stops working.

[0051] (3) After the net cage slides into the corresponding position of the net cage storage ring, the belt drives the buckle to slide a distance in the opposite direction of the net cage sliding into the net cage storage ring, so that the buckle is disengaged from the net cage. The lifting screw lifts up and drives the connecting rod and belt transmission device to rise at the same time. The first drive motor is started so that the driving wheel drives the driven 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.

[0052] (4) The lifting screw descends and simultaneously drives the connecting rod and belt drive device to descend, so that the push plate of the buckle engages with the net box. Then the belt drive device drives the buckle to push the net box to slide out of the net box storage ring along the guide rail. After the net box slides out of the net box storage ring along the guide rail, the belt drives the buckle to continue moving a distance, so that the buckle disengages from the net box, and the net box replacement is completed.
