Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, specifically to a device for quantitatively dispensing feed for deep-sea aquaculture. Background Technology

[0002] Deep-sea aquaculture mainly refers to aquaculture conducted in deep-water, offshore areas using large-scale fishery equipment such as gravity cages, truss cages, and aquaculture vessels. This aquaculture method is supported by mechanization, automation, and intelligent technologies, enabling efficient aquaculture in a wider sea area and reducing the impact on the nearshore ecological environment. In recent years, deep-sea aquaculture technology has continued to advance. The application of modern aquaculture equipment such as gravity cages and truss cages has significantly increased the scale and efficiency of deep-sea aquaculture. The construction of large-scale aquaculture vessels has also provided new possibilities for deep-sea aquaculture, enabling aquaculture in more complex marine environments. In marine aquaculture, commonly used feed types include: biological feed: such as microalgae (Chlorella, Platycladus, Chaetoceros, etc.) and animal biological feed (rotifers, cladocerans, etc.), which are characterized by comprehensive nutrition and good palatability; plant feed: suitable for certain aquaculture species, which can improve aquaculture efficiency; animal feed: mainly used to meet the nutritional needs of carnivorous aquatic organisms; and comprehensive feed: combining the advantages of plant and animal feed, suitable for a variety of aquaculture objects.

[0003] In the field of deep-sea aquaculture, to achieve large-scale and uniform feeding, the use of automatic feeding platforms that can detach from fixed bases and drift with the water flow has become an effective solution. These platforms are remotely deployed and retrieved by shore-based electric hoists that extend and retract steel cables. However, this mode faces a series of severe technical challenges brought about by the dynamic marine environment when operating in actual sea areas, which seriously restricts its reliability, automation level and applicability. The water level in the aquaculture area will fluctuate significantly due to the influence of tides, hydrology and climate. When the water level rises, the floating platform rises accordingly, while the position of the fixed base on the shore remains unchanged. This causes a serious misalignment in vertical height between the docking mechanism (such as the snap-fit ​​column) and the receiving mechanism (such as the snap-fit ​​groove) on the fixed base when the platform is retrieved, resulting in a "vertical misalignment". Existing rigid connection or simple guide design cannot automatically compensate for this height difference, causing the docking parts to fail to mesh accurately during the retrieval process. This can lead to retrieval failure or even mechanical collision damage to the equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device for quantitatively dispensing feed for deep-sea aquaculture, thereby solving the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A deep-sea aquaculture feed dispensing device includes a buoyancy frame, with several buoyancy tanks fixedly installed on the bottom surface of the buoyancy frame. A feed tank is fixedly installed inside the buoyancy frame, and a fixing ring is fixedly fitted onto the outer circular wall of the feed tank. A dispensing assembly is disposed on the outer circular wall of the feed tank for dispensing feed for deep-sea aquaculture. The dispensing assembly includes a docking platform disposed on the outer circular wall of the fixing ring. A fixing platform is located on the side of the docking platform away from the feed tank. Two locking grooves are formed on the side of the docking platform away from the feed tank. Two locking posts are formed on the side of the fixing platform near the docking platform. The locking posts are movably engaged with the locking grooves. Movable arms are respectively provided on both sides of the fixing platform. A shore support is provided on one side of each of the two movable arms. An electric hoist is fixedly installed on the bottom surface of the shore support. A steel rope hole is formed on one side of the fixing platform. An auxiliary docking component is disposed inside the steel rope hole, which uses the force of the electric hoist's steel rope to rotate and dock the docking platform and the fixing platform. Using the above technical solution, by setting up an electric hoist, when workers are discharging feed for deep-sea aquaculture, firstly, the shore support and electric hoist are installed on the shore, and the feed bucket and buoyancy bucket are placed in the water. At this time, the buoyancy bucket floats on the water surface. Then, the electric hoist is activated, releasing the steel cable. Workers push the feed bucket, causing it to move the docking platform away from the fixed platform. Subsequently, the buoyancy bucket floats on the water surface and drifts freely with the current in the aquaculture area. Before this, workers put the feed into the feed bucket. While the feed bucket is drifting freely in the aquaculture area, the feed inside the bucket is released into the water, thus completing the deep-sea aquaculture feed discharging. After the feed is discharging, the electric hoist is activated to reel in the steel cable. The steel cable pulls the connecting column, moving the docking platform, feed bucket, buoyancy frame, and buoyancy bucket towards the fixed platform. When the docking platform is close to the fixed platform, the locking column engages with the locking groove to limit the docking platform.

[0006] Preferably, a connecting hole is provided on one side of the shore support, and a first rotating block is fixedly installed on the side of the two movable arms that are close to each other. A first rotating ring is fixedly installed on both sides of the fixed platform. The first rotating ring is movably sleeved with the first rotating block. An installation groove is provided on the side of the docking platform that is close to the fixed platform. A connecting column is fixedly installed inside the installation groove. The steel rope of the electric hoist passes through the connecting hole and the steel rope hole and is fixedly installed with the connecting column. Limit plates are fixedly installed on both sides of the movable arm.

[0007] Using the above technical solution, by starting the electric hoist to wind up the steel rope, the material bucket, docking platform, buoyancy frame and buoyancy tank can be retrieved as a whole to the fixed platform position. When the docking platform is close to the fixed platform, the locking post is accurately embedded in the locking groove, completing the initial positioning and fixing, realizing the remote release, downstream feeding and automatic retrieval of the bait delivery device.

[0008] Preferably, the auxiliary docking assembly includes: two resistance wheels, both of which are disposed inside the steel cable hole; a central shaft is fixedly installed at both ends of each resistance wheel; a protruding rod is fixedly installed at both ends of each central shaft; two vibration grooves are formed on one side of the interior of the fixed platform; two movable holes are formed on one side of the interior of each vibration groove; the movable holes communicate with the steel cable hole; the central shaft is movably sleeved with the movable holes; the protruding rod is located inside the vibration groove; two guide posts are fixedly installed inside the fixed platform; two guide holes are formed on the top surface of each locking post; the guide holes are movably sleeved with the guide posts; and a tension spring is movably sleeved on the outer circular wall of each guide post.

[0009] Using the above technical solution, with the fixed platform in place, the electric hoist's steel cable passes through the connection hole and steel cable hole to connect to the docking platform. Since the electric hoist and the shore support are stationary on the shore, when the water level in the deep-sea aquaculture area rises, the buoyancy tank naturally floating on the water surface causes the docking platform to rise. At this time, the position of the docking platform and the fixed platform intersect. The docking platform rises along with the buoyancy frame and buoyancy tank, while the fixed platform remains stationary. Therefore, the initial position of the fixed platform is lower. When the buoyancy frame is retrieved, the docking platform and the fixed platform, due to their intersecting positions,... Inaccurate docking is impossible because the steel cable passes through the fixed platform and connects to the docking platform. When the docking platform is raised, the position of the electric hoist's steel cable connection end also rises. At this time, the electric hoist's steel cable is inclined from the docking platform to the fixed platform, while the fixed platform is close to the electric hoist. Therefore, the steel cable inside the cable hole is inclined from bottom to top. Simultaneously, the fixed platform is squeezed upwards from inside the cable hole by the electric hoist's steel cable, causing it to rotate upwards. The docking platform is pulled downwards by the electric hoist's steel cable, and then the fixed platform drives the first rotating ring to rotate upwards around the first rotating block. The two locking posts are aligned upwards, and the docking platform, pulled by the steel cable, drives the second rotating ring to rotate downwards around the second rotating block. This ensures that the locking slots and locking posts remain aligned even when the docking platform and the fixed platform are staggered vertically. Simultaneously, the steel cable inside the cable hole rotates against the surface of the upper resistance wheel. The friction generated by the retraction of the electric hoist's steel cable against the resistance wheel causes the resistance wheel to rotate. The resistance wheel then drives the central shaft and the convex rod to rotate clockwise. When the protruding end of the convex rod abuts against the bottom surface of the upper locking post, the rotation of the convex rod... The locking pin is pushed upward along the outside of the guide pin, and the lower locking pin is pulled upward by the tension spring. When the buoyancy frame and docking platform are pulled to the position near the fixed platform on the shore, the steel cable gradually loosens inside the steel cable hole. At the same time, the rotational power of the steel cable driving the resistance wheel, the central shaft and the cam is also weakened. At this time, the tension spring causes the locking pin to rebound, and through the elastic force of the tension spring, the two locking pins can vibrate up and down frequently. This prevents the locking pins from being unable to align with the locking slot when the waves cause the buoyancy frame, buoyancy tank and docking platform to float, thus affecting the docking of the locking slot and the locking pin.

[0010] Preferably, the tension spring is located between the two locking posts, and the tension spring is fixedly installed with the locking posts. The steel rope of the electric hoist passes between the two resistance wheels. A second rotating ring is fixedly installed on both sides of the docking platform. Two stabilizing platforms are provided on the outer circular wall of the material barrel. A second rotating block is fixedly installed on the side of the two stabilizing platforms that are close to each other. The second rotating block is movably sleeved with the second rotating ring.

[0011] Using the above technical solution, when the buoyancy frame and docking platform are pulled to a position close to the fixed platform on the shore, the steel cable gradually loosens inside the steel cable hole. At the same time, the rotational power of the steel cable driving the resistance wheel, central column and convex rod will also weaken. At this time, the tension spring causes the locking pin to rebound, and through the elastic force of the tension spring, the two locking pins can be made to vibrate up and down frequently, preventing the locking pins from being unable to align with the locking slot when the waves cause the buoyancy frame, buoyancy tank and docking platform to float, thus affecting the docking of the locking slot and the locking pin.

[0012] Preferably, the top surface of the docking platform is provided with a docking component for restricting the material bucket to the shore. The docking component includes: a slot, which is formed on the top surface of the docking platform; a spring column is fixedly installed on one side of the slot; a rotating groove is formed on the top surface of the platform; a rotating column is fixedly installed inside the rotating groove; a torsion spring is movably sleeved on the outer circular wall of the rotating column; a limiting frame is provided inside the rotating groove; a rotating hole is formed on one side of the limiting frame; the rotating hole is movably sleeved with the rotating column; and a locking plate is fixedly installed on one side of the limiting frame.

[0013] Using the above technical solution, when the docking platform and the fixed platform are close together, the top of the docking platform presses against the bottom surface of the limiting frame. Then the limiting frame rotates around the rotating column and lifts slightly upward. When the docking platform and the fixed platform are fully in contact, one end of the limiting frame and the snap-fit ​​plate enter the inside of the snap-fit ​​groove under the action of the torsion spring's rebound force. Then the snap-fit ​​plate and the elastic column are interlocked and snapped together. Thus, the limiting frame can restrict the docking platform and the fixed platform together so that the material bucket can be docked at the shore.

[0014] Preferably, a limiting frame is fixedly installed on the top surface of the shore support. The limiting frame has two transmission rods inside, which are movably connected to the limiting frame. Two sprockets are fixedly sleeved on the outer circular wall of the transmission rods. Each pair of sprockets forms a group, and a chain is meshed on the outer circular wall of each group of sprockets. The side of the chain closest to the fixed platform is fixedly installed to the movable arm.

[0015] Using the above technical solution, through the set movable arm, the operator uses a servo motor. The drive shaft of the servo motor rotates, driving the transmission rod and sprocket to rotate, which in turn drives the chain to rotate. At this time, the chain drives the movable arm and the fixed platform to move upward, thereby raising the docking position of the fixed platform and the docking platform. By adjusting the position of the fixed platform up and down, the height of the fixed platform can be adaptively adjusted according to the influence of the water level of the deep-sea aquaculture area on the docking platform.

[0016] Preferably, two fixed claws are fixedly installed on the bottom surface of the fixed platform, a movable claw is provided on one side of the fixed claw, a threaded groove is opened on the side of the fixed claw near the movable claw, two limiting rods are fixedly installed on the side of the fixed claw near the movable claw, a threaded rod is provided on one side of the movable claw, the threaded rod passes through the movable claw and is threadedly connected to the threaded groove, and the movable claw is movably sleeved with the limiting rod.

[0017] Using the above technical solution, when installing the fixed platform and electric hoist on the shore using the movable claw, the fixed platform can be placed on the shore fence of the aquaculture area, with the fence positioned between the fixed claw and the movable claw. Then, by rotating the threaded rod, the movable claw moves towards the position of the fixed claw, and the fixed claw and movable claw gradually approach each other and get close to the surface of the fence. Subsequently, the worker tightens the threaded rod, clamping the fixed claw and movable claw onto the fence, thus facilitating the fixing of the fixed platform and electric hoist to the waterside fence of deep-sea aquaculture.

[0018] In summary, the present invention has the following main beneficial effects: 1. This invention, through the linkage rotation design of the fixed platform and the docking platform, automatically compensates for the vertical height difference between the two caused by the rise and fall of the water level, ensuring that the key docking component, the locking post, and the slot always maintain alignment in the spatial trajectory. This fundamentally solves the rigid docking obstacle caused by water level fluctuations. By using the movement of the recovery steel rope itself to drive a cam-spring mechanism, the locking post generates high-frequency micro-amplitude vibration. This is equivalent to providing a dynamic "addressing" capability at the moment of final docking, which can overcome the high-frequency shaking of the platform caused by sea waves and greatly improve the reliability and robustness of successful docking in complex sea conditions.

[0019] 2. This invention achieves electric adjustment of the vertical position of the fixed platform through a chain transmission mechanism driven by a servo motor. This enables the system to actively adapt to changes in water level in aquaculture areas caused by factors such as tides and rainfall, fundamentally eliminating the misalignment of the docking surface caused by water level differences in advance. It upgrades the docking conditions from "passive self-adaptation" to "active pre-alignment", significantly improving the success rate of one-time docking and the convenience of operation.

[0020] 3. By introducing a buffer module consisting of a stabilizing platform and a reset spring, this invention adds elastic degrees of freedom to the recovery path of the docking platform. This design can effectively absorb and dissipate the transient mechanical energy generated by the sudden force on the steel rope or the surge impact on the platform during the recovery process, transforming rigid impact into flexible gradual motion, greatly improving the stability of system operation, reducing impact wear on structural components and drive components, extending the service life of the equipment, and enhancing the reliability of operation in undulating sea conditions.

[0021] 4. This invention uses a rotatable limiting frame and locking plate driven by a torsion spring to automatically lock into the slot of the docking platform during recycling, achieving automatic, fast and secure locking of the device after recycling, ensuring the stability of the material bucket when docked at the shore, and preventing it from swinging or falling off with the wind and waves.

[0022] 5. This invention drives the moving claw to move towards the fixed claw by rotating the threaded rod, thereby clamping the shore fence. It provides a flexible and adjustable installation method, which can quickly and securely install the entire fixed platform on various different shore environments, enhancing the adaptability of the equipment.

[0023] 6. This invention uses a mechanism consisting of a drive motor, a cam, and a compression spring to drive the compaction shell to compress loose bait into blocks within the cavity. The ratchet and locking pawl are used to achieve precise locking of a single movement, completing the intermittent feeding cycle and compressing the bait into blocks, effectively reducing loss and waste during the feeding process. The intermittent feeding method is more in line with the feeding habits of fish and is conducive to scientific aquaculture.

[0024] 7. This invention achieves precise measurement and data recording of each feeding amount by using a weighing sensor to measure the weight of the feed isolated in the compaction shell cavity during the compaction process. This provides a basis for accurately controlling the feeding amount, optimizing breeding costs, and conducting scientific data analysis.

[0025] 8. This invention uses a stepper motor to drive gears and racks, which in turn move the weighing plate horizontally. This allows the weighed bait blocks on the plate to align with the discharge hole and fall down under gravity, thus achieving automated closed-loop control of the entire process of "compacting, weighing, and discharging". This ensures that the quantitative and intermittent feeding action can be carried out accurately and orderly in a cyclical manner. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7A deep-sea aquaculture feed dispensing device includes a buoyancy frame 1, with several buoyancy tanks 2 fixedly installed on the bottom surface of the buoyancy frame 1. A feed tank 4 is fixedly installed inside the buoyancy frame 1, and a fixing ring 3 is fixedly fitted onto the outer circular wall of the feed tank 4. A dispensing component is provided on the outer circular wall of the feed tank 4 for dispensing feed for deep-sea aquaculture. The dispensing component includes a docking platform 5, which is located on the outer circular wall of the fixing ring 3. A fixing platform 6 is provided on the side of the docking platform 5 away from the feed tank 4. Two locking grooves 8 are formed on the side of the docking platform 5 away from the feed tank 4. Two locking posts 9 are provided on the side of the fixing platform 6 near the docking platform 5, and the locking posts 9 are movably engaged with the locking grooves 8. The fixing platform 6 has two... The device is equipped with movable arms 67, and a bank support 66 is provided on one side of each movable arm 67. An electric hoist 7 is fixedly installed on the bottom surface of the bank support 66. A connection hole 10 is provided on one side of the bank support 66. A first rotating block 68 is fixedly installed on the side of each movable arm 67 that is close to each other. A first rotating ring 69 is fixedly installed on both sides of the fixed platform 6. The first rotating ring 69 is movably connected to the first rotating block 68. A second rotating ring 65 is fixedly installed on both sides of the docking platform 5. A second rotating block 64 is fixedly installed on the side of each stable platform 63 that is close to each other. The second rotating block 64 is movably connected to the second rotating ring 65. A steel rope hole 70 is provided on one side of the fixed platform 6.

[0030] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The docking platform 5 has an installation groove 11 on the side near the fixed platform 6. A connecting column 12 is fixedly installed inside the installation groove 11. The steel rope of the electric hoist 7 passes through the connecting hole 10 and is fixedly installed with the connecting column 12. The top surface of the docking platform 5 is provided with a docking component for restricting the material bucket 4 to the shore. The docking component includes: a slot 13, which is opened on the top surface of the docking platform 5. A spring column 14 is fixedly installed on one side inside the slot 13. The top surface of the fixed platform 6 has a rotating groove 15. A rotating column 16 is fixedly installed inside the rotating groove 15. A torsion spring is movably sleeved on the outer circular wall of the rotating column 16. A limiting frame 17 is provided inside the rotating groove 15. A rotating hole 19 is opened on one side of the limiting frame 17. The rotating hole 19 is movably sleeved with the rotating column 16. A snap plate 18 is fixedly installed on one side of the limiting frame 17. Limit plates 20 are fixedly installed on both sides of the movable arm 67.

[0031] By using an electric hoist 7 and a fixed platform 6 installed on the shore, this system automates the feeding and retrieval of feed. During operation, the worker places the feed bucket 4 and the buoyancy bucket 2, which provides buoyancy, into the water. After the electric hoist 7 is activated to release the steel cable, the entire device can float freely with the water flow under the support of the buoyancy bucket 2 with just a gentle push on the feed bucket 4. During this process, the feed in the feed bucket 4 is continuously fed into the aquaculture area, completing large-scale feeding. After the operation is completed, the electric hoist 7 is activated to reel in the steel cable, which retrieves the feed bucket 4, docking platform 5, buoyancy frame 1, and buoyancy bucket 2 as a whole back to the fixed platform 6. When the docking platform 5 approaches the fixed platform 6, the locking post 9 precisely embeds into the locking groove 8. Inside, the initial positioning and fixation are completed, enabling remote release, downstream feeding, and automatic retrieval of the bait delivery device. Through the set limiting frame 17, the system can automatically and firmly lock during retrieval. When the docking platform 5 and the fixed platform 6 are attached, the top of the limiting frame 17 is lifted, causing it to rotate around the rotating column 16. After the two are fully attached, under the action of the torsion spring, one end of the limiting frame 17 and the snap-fit ​​plate 18 quickly snap into the slot 13 of the docking platform 5. At this time, the snap-fit ​​plate 18 and the elastic column 14 are interlocked and locked, thus tightly restricting the docking platform 5 and the fixed platform 6 together, ensuring that the feed bucket 4 is stably docked on the shore. After the device is retrieved, it is automatically locked to the fixed platform.

[0032] By using the limiting plate 20, this system ensures the accuracy of the recycling docking. When the docking platform 5 moves toward the fixed platform 6 and is about to overlap, it first enters the guide channel formed by the two limiting plates 20. This channel can effectively correct the final position of the docking platform 5, making it accurately aligned with the fixed platform 6, thereby ensuring that the snap-fit ​​post 9 can be smoothly inserted into the snap-fit ​​groove 8 without any deviation.

[0033] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The steel rope hole 70 is equipped with an auxiliary docking assembly that uses the force of the electric hoist 7 steel rope to rotate and dock the docking platform 5 and the fixed platform 6. The auxiliary docking assembly includes two resistance wheels 71, both of which are located inside the steel rope hole 70. A central shaft column 72 is fixedly installed at both ends of the resistance wheel 71, and a protruding rod 73 is fixedly installed at both ends of the central shaft column 72. Two vibration grooves 78 are opened on one side of the interior of the fixed platform 6, and two movable holes 74 are opened on one side of the interior of the vibration grooves 78. The movable holes 74 are connected to the steel rope hole 70. The central shaft column 72 is movably sleeved with the movable holes 74. The protruding rod 73 is located inside the vibration groove 78 and is fixed. Two guide columns 75 are fixedly installed inside the platform 6. Two guide holes 77 are opened on the top surface of the snap-fit ​​column 9. The guide holes 77 are movably sleeved with the guide columns 75. A tension spring 76 is movably sleeved on the outer circular wall of the guide column 75. The tension spring 76 is located between the two snap-fit ​​columns 9 and is fixedly installed with the snap-fit ​​columns 9. The steel rope of the electric hoist 7 passes between the two resistance wheels 71. A second rotating ring 65 is fixedly installed on both sides of the docking platform 5. Two stabilizing platforms 63 are provided on the outer circular wall of the material bucket 4. A second rotating block 64 is fixedly installed on the side of the two stabilizing platforms 63 that are close to each other. The second rotating block 64 is movably sleeved with the second rotating ring 65.

[0034] Through innovative mechanical structure design, the deployment platform can reliably dock with the fixed platform on the shore even when the water level changes. The fixed platform 6 is connected to the floating docking platform 5 via the steel cable of the electric hoist 7, through the connecting hole 10 and the steel cable hole 70. When the water level in the aquaculture area rises, the docking platform 5, which is suspended by the buoyancy tank 2, rises accordingly, causing it to be misaligned vertically with the fixed platform 6. At this time, if it is directly retrieved, the two will not be able to dock accurately due to the height difference. As the docking platform rises, the connecting steel cable is inclined from bottom to top in the steel cable hole 70 of the fixed platform. This inclined steel cable generates an upward lifting torque on the fixed platform 6 and a downward pulling torque on the docking platform 5. Under the action of this torque: The fixed platform 6 drives its first rotating ring 69 at its bottom to rotate upward around the first rotating block 68, causing the entire fixed platform and the locking pin 9 mounted on it to tilt upward. Under the tension of the steel cable, the docking platform 5 drives its second rotating ring 65 to rotate downward around the second rotating block 64, causing the docking platform and its locking groove 8 to tilt downward. Through this up-and-down linkage, even if there is a height difference between the two, the key locking pin 9 and locking groove 8 can be spatially readjusted to a mutually aligned state. During the retrieval process, the inclined steel cable slides closely against the surface of the resistance wheel 71 fixed on the fixed platform. Friction drives the resistance wheel to rotate, and the resistance wheel drives the convex rod 73 to rotate clockwise through the central shaft 72. When the protruding end of the convex rod abuts against the bottom surface of the upper locking post 9, it pushes the locking post to move upward along the guide post 75 and stretches the tension spring 76 connected to it. As the steel rope winding angle changes, this driving force changes periodically, causing the locking post to continuously generate high-frequency micro-vibrations up and down under the action of the spring. This vibration effectively eliminates the last few centimeters of alignment error caused by the slight floating of the platform due to the waves, making the locking post act like an active probe, which greatly improves the success rate of inserting the locking groove in a wavy water environment.

[0035] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A limiting frame 79 is fixedly installed on the top surface of the shore support 66. The limiting frame 79 has two transmission rods 80 inside, which are movably connected to the limiting frame 79. Two sprockets 81 are fixedly sleeved on the outer circular wall of the transmission rods 80. Each pair of sprockets 81 forms a group. A chain 82 is meshed on the outer circular wall of each group of sprockets 81. The side of the chain 82 closest to the fixed platform 6 is fixedly installed with the movable arm 67. A servo motor 83 is fixedly installed on one side of the limiting frame 79. The drive shaft of the servo motor 83 is fixedly installed with one end of the transmission rod 80. The limiting frame 79 is slidably connected to the movable arm 67.

[0036] Two arc-shaped platforms 60 are fixedly installed on the outer circular wall of the material bucket 4. The two arc-shaped platforms 60 are arranged at an interval between vertical positions. Two stabilizing columns 87 are fixedly installed on one side of the two arc-shaped platforms 60. The stabilizing platform 63 is movably connected to the stabilizing column 87. The top and bottom surfaces of the stabilizing platform 63 are respectively provided with positioning rings 62. The positioning rings 62 are fixedly connected to the stabilizing column 87. A return spring 61 is fixedly installed between the stabilizing platform 63 and the positioning ring 62.

[0037] With the movable arm 67 in place, the operator uses the servo motor 83. The drive shaft of the servo motor 83 rotates, which drives the transmission rod 80 and the sprocket 81 to rotate, which in turn drives the chain 82 to rotate. At this time, the chain 82 drives the movable arm 67 and the fixed platform 6 to move upward, thereby raising the docking position of the fixed platform 6 and the docking platform 5. By adjusting the position of the fixed platform 6 up and down, the height of the fixed platform 6 can be adaptively adjusted according to the influence of the water level of the docking platform 5 on the deep-sea aquaculture area.

[0038] With the stabilizing platform 63 in place, when the docking platform 5 is pulled by the steel cable, the docking platform 5 moves downward, causing the stabilizing platform 63 to move downward and squeezing the reset spring 61. This buffers the stabilizing platform 63 and the docking platform 5, preventing the steel cable of the electric hoist 7 from being pulled hard.

[0039] Based on the above embodiments, refer to Figure 2 , Figure 3 and Figure 10 Two fixed claws 21 are fixedly installed on the bottom surface of the fixed platform 6. A movable claw 22 is provided on one side of the fixed claw 21. A threaded groove 23 is opened on the side of the fixed claw 21 near the movable claw 22. Two limit rods 25 are fixedly installed on the side of the fixed claw 21 near the movable claw 22. A threaded rod 24 is provided on one side of the movable claw 22. The threaded rod 24 passes through the movable claw 22 and is threadedly connected to the threaded groove 23. The movable claw 22 and the limit rod 25 are movably sleeved.

[0040] With the movable claw 22 and fixed claw 21, this system can flexibly adapt to different shore environments. During installation, the fixed platform 6 is placed on the shore fence, so that the fence is between the fixed claw 21 and the movable claw 22. By rotating the threaded rod 24, the movable claw 22 can be driven to move closer to the fixed claw 21, thereby clamping the fence. After tightening the threaded rod 24, the clamping force can be used to securely install the entire fixed platform 6 and the electric hoist 7 on the water's edge, providing an adjustable clamping mechanism for fixing the equipment to the shore fence.

[0041] Based on the above embodiments, refer to Figure 1 , Figure 4 , Figure 5 , Figure 8 , Figure 11 , Figure 12 , Figure 13 and Figure 14The top surface of the feed hopper 4 is equipped with a metering component for dispensing bait. The metering component includes a fixing frame 26, which is fixedly installed on the top surface of the feed hopper 4. A mounting frame 27 is fixedly installed on one side of the fixing frame 26, and a drive motor 28 is fixedly installed inside the mounting frame 27. A pressing rod 29 is provided inside the feed hopper 4. Movable columns 30 are fixedly installed on both sides of the pressing rod 29. A swing arm 31 is provided on the top surface of the pressing rod 29. The swing arm 31 is movably connected to the movable columns 30. An active dial 32 is provided on one side of the swing arm 31. A rotating column 33 is fixedly installed on one side of the active dial 32 and is movably connected to the swing arm 31. A rotation hole 34 is opened on one side of the active dial 32. A ratchet is fixedly installed inside the fixing frame 26. A cam block 36 is movably fitted onto the inner circular wall of the wheel 39 and the rotating hole 34. One end of the cam block 36 passes through the fixed frame 26 and the ratchet 39 and is fixedly installed on the drive shaft of the drive motor 28. A pin 35 is fixedly installed on one side of the active dial 32, and a rotating rod 37 is fixedly installed on the other side of the active dial 32. A locking arc pawl 38 is movably fitted onto the outer circular wall of the rotating rod 37. The locking arc pawl 38 is engaged with the ratchet 39. A fixed plate 41 is fixedly fitted inside the material barrel 4. A compaction shell 40 is fixedly installed on the bottom surface of the pressing rod 29. An installation ring 42 is fixedly fitted onto the outer circular wall of the pressing rod 29. A compression spring 43 is movably fitted onto the outer circular wall of the pressing rod 29. The top and bottom surfaces of the compression spring 43 are fixedly installed to the fixed plate 41 and the installation ring 42, respectively. By using components such as the drive motor 28, cam block 36, and compression spring 43, this system achieves quantitative compaction and block feeding of bait. The drive motor 28 drives the cam block 36 to rotate continuously. When the cam block 36 presses the pin 35, it pushes the entire transmission mechanism and compresses the compression spring 43. Once the mechanism passes the dead point, the compressed spring 43 releases energy instantly, driving the lowering rod 29 and the compaction shell 40 to rush down at high speed, pressing the bait in the material bucket 4 into the cavity of the compaction shell 40 to form a dense bait block. Subsequently, the mechanism resets under the drive of the cam and recompresses the compression spring 43. At the same time, the locking pawl 38 engages in the tooth groove of the ratchet 39 to reliably lock the mechanism, completing one working cycle, compressing loose bait into blocks, and realizing intermittent quantitative feeding.

[0042] Based on the above embodiments, refer to Figure 4 , Figure 5 , Figure 11 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18The feed hopper 4 is equipped with a weighing component for discharging bait. The weighing component includes a partition plate 44, which is fixedly fitted inside the feed hopper 4. The bottom surface of the partition plate 44 has a moving groove 45. A moving platform 49 is movably fitted inside the moving groove 45. A detection groove 56 is provided on the top surface of the moving platform 49. A weighing sensor 57 is fixedly installed on the bottom surface of the detection groove 56. A weighing plate 58 is fixedly installed on the top surface of the weighing sensor 57. The weighing plate 58 is movably fitted with the detection groove 56. A feed drop hole 46 is provided on the top surface of the partition plate 44.

[0043] The moving trough 45 has sliding grooves 47 on both sides inside, and a limiting hole 48 is provided on the bottom surface of the sliding groove 47. The moving table 49 has a discharge hole 51 on the top surface. The moving table 49 has sliders 50 fixedly installed on both sides, and the sliders 50 are slidably connected to the sliding grooves 47. A rack 52 is fixedly installed on one side of the right slider 50. A gear 53 is movably sleeved inside the limiting hole 48. The gear 53 is meshed with the rack 52. A mounting bracket 54 is fixedly installed on the bottom surface of the partition plate 44. A stepper motor 55 is fixedly sleeved inside the mounting bracket 54. The drive shaft of the stepper motor 55 is fixedly installed with the gear 53. A feeding hopper 59 is fixedly installed on the outer circular wall of the material barrel 4 and extends into the interior of the material barrel 4.

[0044] With the weighing sensor 57, this system can accurately measure the amount of feed each time. When the feed is in the feed hopper 4, it is piled up on the weighing plate 58. When the compaction shell 40 is pressed down, only the feed in its cavity is isolated and pressed on the weighing plate 58. At this time, the weighing sensor 57 can accurately detect the weight of this part of the feed without being disturbed by other feed in the hopper. It can perform separate and accurate weight detection on each feed that is about to be compacted.

[0045] Through the discharge hole 51 and the weighing plate 58 driven by the stepper motor 55, gear 53, and rack 52, this system realizes the controllable discharge of compacted bait. After the bait is weighed on the weighing plate 58, the stepper motor 55 starts and drives the weighing plate 58 to move horizontally through the gear and rack transmission, so that it moves away from under the compaction shell 40. When the bait block on the weighing plate 58 is aligned with the discharge hole 51, the bait block falls automatically due to gravity, completing one feeding cycle. After that, the weighing plate 58 is reset to prepare for the next cycle, controlling the discharge of the weighed and compacted bait block from the equipment.

[0046] Based on the above embodiments, refer to Figure 1 and Figure 2 Several stabilizing rods 84 are fixedly installed on the outer circular wall of the material barrel 4. A gravity ball 86 is fixedly installed on the bottom surface of the stabilizing rod 84. A buoyancy airbag 85 is fixedly sleeved on the outer circular wall of the stabilizing rod 84.

[0047] By using the gravity ball 86 and several evenly arranged buoyancy airbags 85, the entire buoyancy frame 1, buoyancy tank 2 and fixing ring 3 can be counterweighted. When the buoyancy tank 2 and gravity ball 86 have a deep draft, the buoyancy airbags 85 can provide additional buoyancy to the gravity ball 86 and buoyancy tank 2.

[0048] Working principle: Please refer to Figures 1-18 As shown, by using the movable claw 22, when the worker installs the fixed platform 6 and the electric hoist 7 on the shore, the fixed platform 6 can be placed on the shore fence of the aquaculture area, with the fence positioned between the fixed claw 21 and the movable claw 22. Then, by rotating the threaded rod 24, the threaded rod 24 rotates, causing the movable claw 22 to move towards the position of the fixed claw 21. The fixed claw 21 and the movable claw 22 gradually approach each other and get close to the surface of the fence. The worker then tightens the threaded rod 24, clamping the fixed claw 21 and the movable claw 22 onto the fence, thus facilitating the fixing of the fixed platform 6 and the electric hoist 7 onto the waterside fence of the deep-sea aquaculture. Using the electric hoist 7, when the worker feeds the deep-sea aquaculture, first, the shore support 66 and the electric hoist 7 are installed on the shore, and the feed bucket 4 and the buoyancy bucket 2 are placed in the water. At this time, the buoyancy bucket 2 floats on the water surface. Then, by starting the electric hoist 7, the feed bucket 4 can be lifted into the water. Release the steel cable of the electric hoist 7, and then the operator pushes the feed bucket 4, causing it to move the docking platform 5 away from the fixed platform 6. Subsequently, the buoyancy bucket 2 floats on the water surface and drifts freely with the current in the aquaculture area. Before this, the operator puts feed into the feed bucket 4. As the feed bucket 4 drifts freely in the aquaculture area, the operator releases the feed from inside the bucket 4 into the water to deliver the deep-sea aquaculture feed. After the feed is delivered, the operator uses the electric hoist 7 to start and rewind the steel cable. The steel cable of the electric hoist 7 then pulls the connecting column 12, moving the docking platform 5, feed bucket 4, buoyancy frame 1, and buoyancy bucket 2 towards the fixed platform 6. When the docking platform 5 approaches the fixed platform 6, the locking column 9 engages with the locking groove 8 to restrain the docking platform 5. If the operator anticipates or encounters a continuous onshore wind that may prevent the delivery device from successfully leaving the shore, the following steps can be taken: First, ensure safe recycling. First, ensure that the buoyancy frame 1, material bucket 4, etc. have been recycled by the electric hoist 7 and reliably locked to the fixed platform 6. 2. Disassembly and transfer: Loosen the threaded rod 24, release the clamping of the moving claw 22 and the fixed claw 21 on the fence, and transport the entire shore support 66, fixed platform 6 and the locked delivery device on it as a whole along the shore to the upwind position of the aquaculture area, that is, the position where the wind blows from the shore to the water surface. 3. Reinstallation: At the new upwind location, use the movable claw 22 and fixed claw 21 to securely install the shore-based system onto the fence. Fourth, release the feed bucket 4 with the wind. Start the electric hoist 7 to release the steel rope and gently push the feed bucket 4. At this time, the wind direction will help to push the device away from the shore more quickly and smoothly and into the aquaculture water for drifting and feeding.

[0049] With the fixed platform 6 in place, the steel cable of the electric hoist 7 passes through the connecting hole 10 and the steel cable hole 70 to connect with the docking platform 5. Since the electric hoist 7 and the shore support 66 are stationary on the shore, when the water level of the deep-sea aquaculture area rises, the buoyancy tank 2, which naturally floats on the water surface, will also cause the docking platform 5 to rise. At this time, the position of the docking platform 5 and the fixed platform 6 intersect. The position of the docking platform 5 rises with the buoyancy frame 1 and the buoyancy tank 2, while the position of the fixed platform 6 remains stationary. Therefore, the initial position of the fixed platform 6 is low. When the buoyancy frame 1 is retracted, the docking platform 5 and the fixed platform 6 cannot accurately dock due to their intersecting positions. Since the steel cable passes through the fixed platform 6 and connects with the docking platform 5, when the position of the docking platform 5 rises, the electric hoist 7... The position of the steel rope connection end will also rise. At this time, the steel rope of the electric hoist 7 is inclined from the position of the docking platform 5 to the fixed platform 6. The fixed platform 6 is close to the position of the electric hoist 7. Therefore, the steel rope inside the steel rope hole 70 is inclined from bottom to top. At this time, the fixed platform 6 is squeezed upward from the inside of the steel rope hole 70 by the steel rope of the electric hoist 7, causing it to rotate upward. The docking platform 5 is pulled downward by the steel rope of the electric hoist 7. Then, the fixed platform 6 drives the first rotating ring 69 to rotate upward around the first rotating block 68 and tilt it, and makes the two locking posts 9 upward. Under the pull of the steel rope, the docking platform 5 drives the second rotating ring 65 to rotate downward around the second rotating block 64. Thus, when the docking platform 5 and the fixed platform 6 are staggered, the locking groove 8 and the locking post 9 can still be aligned with each other.

[0050] The steel rope passing through the steel rope hole 70 rotates in close contact with the surface of the upper resistance wheel 71. The friction generated when the electric hoist 7's steel rope retracts and contacts the resistance wheel 71 causes the resistance wheel 71 to rotate. The resistance wheel 71 then drives the central shaft column 72 and the protruding rod 73 to rotate clockwise. When the protruding end of the protruding rod 73 abuts against the bottom surface of the upper locking post 9, the rotation of the protruding rod 73 pushes the locking post 9 upwards along the outside of the guide post 75, and the tension spring 76 pulls the lower locking post 9 upwards. When the float... When the buoyancy frame 1 and docking platform 5 are pulled to a position near the fixed platform 6 on the shore, the steel cable gradually loosens inside the steel cable hole 70. At the same time, the rotational power of the steel cable driving the resistance wheel 71, the central column 72 and the convex rod 73 will also weaken. At this time, the tension spring 76 causes the locking pin 9 to rebound, and through the elastic force of the tension spring 76, the two locking pins 9 can vibrate up and down frequently. This prevents the locking pins 9 from failing to align with the locking groove 8 when the waves cause the buoyancy frame 1, buoyancy tank 2 and docking platform 5 to float, thus affecting the docking of the locking groove 8 and the locking pin 9.

[0051] With the setting of the limiting frame 17, when the docking platform 5 and the fixed platform 6 are close together, the top of the docking platform 5 presses against the bottom surface of the limiting frame 17. Then the limiting frame 17 rotates around the rotating column 16 and lifts up slightly. When the docking platform 5 and the fixed platform 6 are fully attached, one end of the limiting frame 17 and the snap-fit ​​plate 18 enter the interior of the snap-fit ​​groove 13 under the action of the torsion spring rebound force. Then the snap-fit ​​plate 18 and the elastic column 14 are interlocked and snapped together. Thus, the docking platform 5 and the fixed platform 6 can be restricted together by the limiting frame 17 so that the material bucket 4 can be docked on the shore.

[0052] With the setting of the limiting plate 20, when the docking platform 5 and the fixed platform 6 gradually overlap, the docking platform 5 first enters between the two limiting plates 20. The two limiting plates 20 limit the position of the docking platform 5, so that the position of the docking platform 5 is directly opposite the fixed platform 6, and the locking post 9 is stably inserted into the inside of the locking groove 8.

[0053] Through the compaction shell 40, the operator uses the drive motor 28. The drive shaft of the drive motor 28 rotates, causing the cam block 36 to rotate. The cam block 36 rotates continuously at a constant angular velocity. When the cam block 36 rotates to the position of the pin 35, the cam block 36 presses against the pin 35 and pushes the pin 35. In turn, the pin 35 drives the active dial 32, rotating column 33, swing arm 31, and lowering rod 29 to rotate. While the active dial 32 rotates, it also drives the rotating rod 37 and locking pawl 38 to rotate. Since the compression spring 43 is initially compressed, when the top of the active dial 32 and the locking pawl 38 rotate to the right side of the ratchet 39, the compression spring 43 rebounds and drives the installation... Ring 42, pressing rod 29 and swing arm 31 move downward. During this process, the bait inside the feed hopper 4 is pressed into the compaction shell 40 and then discharged, which facilitates the quantitative feeding of bait. Subsequently, the active dial 32 rotates to the left side of the ratchet 39, which drives the swing arm 31, pressing rod 29 and compaction shell 40 to move upward and reset, and recompresses the compression spring 43. At this time, the locking pawl 38 on the left side engages in the tooth groove of the ratchet 39 to prevent the compression spring 43 from rebounding. The precise engagement between the locking pawl 38 and the ratchet 39 quickly brakes and keeps it stationary, allowing the pressing rod 29 to complete one motion cycle, which facilitates the compaction of the bait into blocks for feeding.

[0054] With the weighing sensor 57 in place, when the bait is inside the feed hopper 4, the bait accumulates on the top surface of the weighing plate 58, and the compaction shell 40 corresponds to the position of the weighing plate 58. When the compaction shell 40 is pressed down, the bait enters the compaction shell 40 and is located on the top surface of the weighing plate 58, while the excess bait is blocked by the compaction shell 40. At this time, the weighing sensor 57 only detects the weight of the bait inside the compaction shell 40, which makes it easy to accurately record the amount of bait put in.

[0055] After the bait is weighed on the top surface of the weighing plate 58 via the discharge hole 51, the stepper motor 55 is started. The drive shaft of the stepper motor 55 rotates, which drives the gear 53 to rotate. The gear 53 then meshes and drives the rack 52 to move linearly. At this time, the weighing plate 58 moves away from the position of the compaction shell 40. Then, the compaction shell 40 gradually overlaps with the discharge hole 51. After that, the bait inside the compaction shell 40 falls out through the discharge hole 51. This process is repeated to achieve intermittent feeding.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
