[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0055] This invention provides a novel bottom-mounted truss lifting and folding intelligent aquaculture cage, such as... Figures 1 to 3 As shown, the system includes a base-mounted truss platform 1, a wire mesh cage, a wire mesh cover 2, a wire mesh cover 3, and a connecting and moving device. Multiple base-mounted truss platforms 1 are provided, each with a wire mesh cage in the center. A wire mesh cover 2 is installed on the wire mesh cage. Each base-mounted truss platform 1 includes an installation platform 4, multiple columns 5, and multiple sets of trusses 6. The columns 5 are evenly distributed below the installation platform 4, and pulley assemblies are installed on the columns 5. The columns 5 are fixedly connected to the four corners of the installation platform 4. Trusses 6 are connected to the columns 5 via mounting bases. A gear lifting structure is provided between the columns 5 and the trusses 6 to drive the entire wire mesh cage to move and lift. The wire mesh cover 3 is located on top of the wire mesh cage to close the top of the cage. The wire mesh cover 3 uses a frame and wire mesh. The cage is composed of a wire mesh made of horizontal and vertical wires. The mesh cover 3 has an automatic covering and retraction function to prevent the escape of aquatic organisms, reduce the entry of external debris, and maintain a stable environment inside the cage. The connecting and moving device includes a mesh bottom frame 7, a movable frame 8, a net-collecting frame 9, and a lifting component. The mesh bottom frame 7 is located on the outer side of the bottom end of the mesh 2 and is used to protect the bottom end of the mesh 2. The movable frame 8 is fixedly connected to the top of the mesh bottom frame 7. The net-collecting frame 9 is set on the top of the movable frame 8 and the outer side of the top end of the mesh 2. The lifting component is set on the base-type truss platform 1. The mesh bottom frame 7, movable frame 8, and net-collecting frame 9 are all connected to the lifting component. The movement of the lifting component can drive the lifting and folding of the cage.

[0056] The truss 6 is connected to the four sides of the column 5, and the entire net cage can be moved by a gear lifting structure to better change the aquaculture depth. The net cage can be lowered to 3-5 meters below the water surface to avoid typhoons, and it is capable of withstanding a category 17 typhoon. It is suitable for sea areas with a water depth of no more than 25 meters and can cope with extreme weather conditions that occur once every 50 years. Since the bottom of the truss 6 is equipped with a net bottom frame 7, the bottom of the net 2 is protected from damage. The four corners of the bottom frame 7 are driven by pulley components to move the bottom frame 7, the movable frame 8 and the net collection frame 9, thereby allowing the net 2 to fold. As the bottom frame 7 rises, the net 2 is folded on all sides. Since there are multiple sets of bottom-mounted truss platform 1 and net cages, each set of net cages is individually connected to the lifting components. The system is equipped with foldable net cages, enabling independent lifting and lowering of multiple cages. This allows for the separate harvesting of different fish species, significantly improving cage utilization. The base-mounted truss platform 1 is also equipped with 360-degree visual monitoring, automated feeding, and overall and individual lifting and lowering control for the net cages and netting 2. It can also monitor wind speed and seawater current, has new energy application capabilities, and provides periodic visual monitoring of underwater fish growth. The entire platform has BeiDou or GPS positioning capabilities and continuous settlement monitoring for each leg. Through intelligent centralized control and remote control, it has wireless communication capabilities within a 10-nautical-mile range from the cliff base, enhancing its usability.

[0057] like Figures 2 to 5 As shown, in order to enable individual net cages to be raised, lowered, and folded, allowing for the separate harvesting of different fish species, thus improving applicability and utilization, the lifting assembly includes a winch 10, a mounting base, a first steel wire rope 11, and a pulley assembly. The winch 10 is mounted on the top of the mounting platform 4 via the mounting base, and the first steel wire rope 11 is fixedly connected to the winch 10. The pulley assembly is mounted on the movable frame 8 and the column 5 for moving the net cages. The pulley assembly includes a connecting plate 12, a fixing rod 13, a pulley 14, and a connecting base. The connecting plate 12 is fixedly connected to the upper and lower ends of the truss 6, and the fixing rod 13 is fixedly connected to the truss 6. The fixed rod 13 is located between the column 5 and the net box, and the pulley 14 is slidably connected to the fixed rod 13 in the middle of the connecting plate 12. The net collection frame 9 is slidably connected to the fixed rod 13. The pulley 14 is connected to the movable frame 8 through the connecting seat. The top of the net 2 is connected to the second steel wire rope 15, which is octagonal. Multiple sets of third steel wire ropes 16 are arranged between the net collection frame 9 and the net 2. Multiple sets of winches 10 are arranged in a circular array. The first steel wire rope 11 connected to the two sets of winches 10 are respectively connected to the net collection frame 9 and the movable frame 8.

[0058] The second wire rope 15 has a diameter of 20mm. The third wire rope 16 is looped around the outside of the net 2. Each group of third wire ropes 16 consists of 8 ropes, spaced 1.5 meters apart. The second and third wire ropes 15 and 16, in conjunction with the net 2, stabilize the net cage frame, maintaining its overall shape and structural strength. This ensures the net cage maintains its designed form in the aquatic environment and withstands loads from aquatic organisms and water pressure. The first wire rope 11 is retracted by two sets of winches 10 installed on the platform 4. The first steel wire rope 11 drives the movable frame 8, the bottom frame of the net 7, and the pulley 14 to move upward along the fixed rod 13, causing the net 2 to move and retract. Then, the other two sets of rolling machines are started to drive the first steel wire rope 11 to retract the net-collecting frame 9. With the support of the third steel wire rope 16, the net 2 is in a regular layered shape, tightly attached to the inside of the net-collecting frame 9, so that the net 2 is folded in an orderly manner from top to bottom. Through the hoops of the eight vertically distributed third steel wire ropes 16, the net 2 is ensured to be stable in the water and easy to operate and unfold.

[0059] like Figures 6 to 8 As shown, to prevent the winch 10 from contacting rainwater or seawater and to prevent corrosion, a protective device is installed on the outside of the winch 10. The protective device includes a protective box 17, a movable opening, a mounting block 18, a first scraper 19, a sealing block 20, a scraping assembly, and a gear moving assembly. The protective box 17 is located on the outside of the protective box 18 and is fixedly installed on the top of the mounting platform 4. The protective box 17 has a movable opening on the side near the first wire rope 11 for the retraction of the first wire rope 11. The mounting block 18 is located on the outside of the movable opening, and one side of the mounting block 18 is fixedly installed to the protective box 17. The first scraper 19 is connected inside the mounting block 18, and the sealing block 20 is located on the inside of the movable opening. The sealing block 20 is attached to the outside of the first wire rope 11. The scraping component is located inside the protective box 17. The gear moving component is located between the sealing block 20 and the scraping component for moving the sealing block 20 and the scraping component. The first wire rope 11 extends through the movable opening to the outside of the protective box 17. The mounting block 18 is located on the outside of the first wire rope 11. The inner wall of the first scraper 19 is attached to the outside of the first wire rope 11 for scraping off the moisture on the first wire rope 11. The scraping component and the gear moving component are both located on both sides of the first wire rope 11. There are two sets of both the scraping component and the gear moving component, and the two sets of scraping components and the two sets of gear moving components are symmetrically arranged with respect to the center of the protective box 17.

[0060] The gear moving assembly includes a second driving member 21, a rotating rod, a gear 22, a first tooth block 23, and a second tooth block 24. The second driving member 21 is fixedly installed on the top inner wall of the protective box 17. The rotating rod is fixedly connected to the bottom of the second driving member 21, and the bottom of the rotating rod is rotatably connected to the top of the mounting platform 4. The gear 22 is fixedly connected to the middle of the rotating rod. The first tooth block 23 is meshed on one side of the gear 22, and the second tooth block 24 is meshed on the other side. The first tooth block 23 and the second tooth block 24 are both slidably connected to the mounting platform 4. The sealing block 20 is fixedly connected to the first tooth block 23, and the scraping component is located on one side of the second tooth block 24.

[0061] In this embodiment, the second drive component 21 can be a motor. The protective box 17 can enclose and protect the winch 10, preventing the net cage from shaking and shifting due to wind and waves in the water environment. This would cause the winch 10 to be subjected to additional impact and vibration, resulting in loosening of connecting parts, accelerated wear of the first wire rope 11, and even deformation of the mechanical structure, affecting the accuracy and stability of its lifting function. The sealing block 20 seals the movable opening and fixes the first wire rope 11, improving the sealing performance inside the protective box 17 and the stability of the first wire rope 11. By activating the second drive component 21, the rotating rod and gear 22 rotate, causing the first tooth block 23 to move the sealing block 20 away from the first wire rope 11, exposing the movable opening and ensuring proper sealing. The sealing block 20 no longer adheres to the first wire rope 11, and at the same time, the second toothed block 24 drives the scraping component to move to the outside of the first wire rope 11. The mounting block 18 can protect the first wire rope 11 at the movable opening. When the winch 10 drives the first wire rope 11 to retract, the inner wall of the first scraper 19 adheres to the outside of the first wire rope 11. When the first wire rope 11 retracts, the water can be scraped off by the first scraper 19. The first scraper 19 removes water from the first wire rope 11, and the scraping component removes water from the outside of the first wire rope 11 again. This prevents water from being brought into the interior of the protective box 17 when the first wire rope 11 is wound up, affecting the use of the winch 10 and causing corrosion and damage to the winch 10.

[0062] like Figure 6 As shown, protective doors 25 are rotatably installed on both sides of the protective box 17. The protective doors 25 are provided with heat dissipation holes for heat dissipation inside the protective box 17.

[0063] By opening the protective door 25, the scraping component can be removed and replaced to prevent wear and tear on the scraping component, which would affect the effect of scraping water. The heat dissipation holes can dissipate heat inside the protective box 17, improving the service life of the sample rolling machine and making it easier to use.

[0064] like Figures 6 to 10As shown, in order to improve the effect of removing moisture from the first wire rope 11 and prevent water from entering the protective box 17 and affecting the performance of the winch 10, the scraping assembly includes a second scraper block 26, a connecting rod 27, a limiting component, a magnetic block 28, an arc-shaped groove, a scraper 29, a guide plate 30, and a collecting block 31. The second scraper block 26 is fixedly connected to the connecting rod 27, and one end of the connecting rod 27 is fixedly connected to one side of the second toothed block 24. The limiting component is set on the second toothed block 24. A magnetic block 28 is set on the side of the second scraper block 26 near the movable opening, and the magnetic blocks 28 are magnetically connected to each other. An arc-shaped groove is opened in the middle of the second scraper block 26, and a scraper 29 is connected in the arc-shaped groove. The guide plate 30 is fixedly connected to one side of the second scraper block 26. The collecting block 31 is fixedly connected to the top of the mounting platform 4. The collecting block 31 is set on the top of the platform 4. The sealing block 20 is located between the winch 10 and the bottom of the first wire rope 11, and is used to collect the scraped seawater. The limiting component includes a first drive member 32, a fixed plate 33, a limiting rod 34, a movable block 35, and a support plate 36. A mounting groove is provided on one side of the second toothed block 24, and the first drive member 32 is fixedly installed in the mounting groove. The fixed plate 33 is fixedly connected to one end of the first drive member 32. The fixed plate 33 is slidably connected to one end of the connecting rod 27. The limiting rod 34 is fixedly connected to the side of the fixed plate 33 near the connecting rod 27. The limiting rod 34 is inserted into one side of the second scraper block 26. A sliding groove is provided on one side of the second toothed block 24, and the movable block 35 is slidably connected in the sliding groove. One end of the support plate 36 is hinged to the fixed plate 33, and the other end is hinged to the movable block 35, for supporting the fixed plate 33.

[0065] In this embodiment, the first driving component 32 can be a motor, and both the first scraper block 19 and the second scraper block 26 are made of rubber. The elastic deformation of the rubber tightly adheres to the rope surface, ensuring the removal of seawater. First, the first driving component 32 is activated, causing the fixed plate 33 to move along the connecting rod 27 towards the second scraper block. This causes the fixed plate 33 to deflect one end of the support plate 36, thereby causing the movable block 35 to move along the groove towards the connecting rod 27. When the fixed plate 33 drives the limiting rod 34 to engage with the second scraper block 26, the support plate 36 deflects to an inclined state to support the fixed plate 33, improving the stability of the fixed plate 33 and the limiting rod 34 in limiting the second scraper block 26. This, in turn, improves the stability of the second scraper block 26 outside the first wire rope 11, preventing the second scraper block 26 from being subjected to... Uneven force weakens the water-scraping effect, bringing seawater into the protective box 17 and damaging the winch 10. When the gear moving assembly causes the second tooth block 24 to move the second scraper block 26 to both sides of the first wire rope 11, the two second scraper blocks 26 are magnetically connected by the magnetic block 28, thus limiting the outer side of the first wire rope 11. This causes the two scraper blades 29 to adhere to one side of the guide plate 30. The scraper blades 29 adhere to the outer side of the first wire rope 11. When the first wire rope 11 moves, the scraper blades 29 scrape off the water on the first wire rope 11. Through the guiding action of the guide plate 30, the water flows along the guide plate 30 into the interior of the collection block 31 for collection, preventing dripping rainwater from entering the protective box 17 and causing the winch 10 to corrode and rust, affecting its use.

[0066] Working principle: In use, the column 5 is fixed below the installation platform 4, and the truss 6 is installed on the column 5 through the connecting seat. The truss 6 is raised and lowered through the gear lifting assembly, which in turn drives the entire net cage to rise and fall, adapting to different aquaculture depths. The winch 10 is installed on the top of the installation platform 4, the bottom frame of the net 2 is installed at the bottom of the net cage, and the net retrieval frame 9 and the third steel wire rope 16 are installed on the outer top of the net 2. The movable frame 8 is connected to the pulley 14 through the connecting seat, and the pulley 14 is then connected to the net retrieval frame 9. Connected to the fixing rod 13, the net cage is fixed in the middle of the entire base-type truss platform 1. The top of the net cage 2 is protected by installing the net cover 3 on top of the net cage. When the net cage needs to be retracted or folded, the first drive unit 32 is activated to move the fixing plate 33 along the connecting rod 27 towards the second scraper block 26. This causes the fixing plate 33 to deflect one end of the support plate 36, thereby causing the movable block 35 to move along the slide groove towards the connecting rod 27. When the fixing plate 33 drives the limiting rod 34 to engage with the second scraper block 26... The support plate 36 tilts to support the fixed plate 33. Then, the second drive component 21 is activated to drive the rotating rod and gear 22 to rotate, causing the first toothed block 23 to move the sealing block 20 away from the first wire rope 11, exposing the movable opening. This prevents the sealing block 20 from adhering to and confining the first wire rope 11. At the same time, when the second toothed block 24 moves the second scraper block 26 to both sides of the first wire rope 11, the two second scraper blocks 26 are magnetically connected through the magnet 28, thus confining them to the outside of the first wire rope 11, allowing the two scraper blocks 26 to move freely. The scraper 29 is attached to one side of the guide plate 30 and to the outer side of the first wire rope 11. When the first wire rope 11 moves, the inner wall of the first scraper 19 is attached to the outer side of the first wire rope 11, and the water can be scraped off by the second scraper 26. When it moves to the second scraper 26, the scraper 29 scrapes off the water on the first wire rope 11 again. Through the guiding action of the guide plate 30, the water flows along the guide plate 30 into the interior of the collection block 31 for collection, thereby removing the water on the first wire rope 11.

[0067] When the first wire rope 11 retracts, two sets of winches 10 are started first, causing the first wire rope 11 to drive the movable frame 8, the bottom frame of the net 7 and the pulley 14 to move upward along the fixed rod 13, so that the net 2 moves and retracts. Then, two other sets of winches 10 are started to drive the first wire rope 11 to drive the net-collecting frame 9 to retract. With the support of the third wire rope 16, the net 2 is in a regular layered shape, tightly attached to the inside of the net-collecting frame 9, so that the net 2 is folded layer by layer from top to bottom in an orderly manner. Since there are multiple bottom-mounted truss platforms 1 and net boxes, each individual net box retracts and folds.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
