Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and in particular to a pneumatically operated self-pressurized net cage device. Background Technology

[0002] Cage aquaculture is currently the main method of marine fish farming, and it is increasingly attracting the attention of coastal countries around the world. With the development of marine aquaculture, pneumatically powered self-propelled piling cages are no longer limited to being submerged; they are required to achieve more functions through raising and lowering. For example, they should be able to submerge to a certain draft depth during routine aquaculture operations, surface during harvesting, and sink to avoid disasters such as typhoons and red tides. Currently, the installation of existing pneumatically powered self-propelled piling cages typically requires the assistance of a piling vessel to insert the piling legs into the seabed to secure the cage and ensure its stability in the ocean. However, the cost of using a piling vessel for piling is high, increasing the overall cost of cage aquaculture. Summary of the Invention

[0003] The main objective of this invention is to propose a pneumatically buoyant self-pressurized pile gabion device, which aims to reduce the installation cost of the pneumatically buoyant self-pressurized pile gabion device.

[0004] To achieve the above objectives, the present invention proposes a pneumatically operated self-pressurized pile cage device, comprising a cage structure, pile leg structure, and a hydraulic lifting device. The cage structure includes columns, support rods, a surrounding well, and a net. The columns and support rods enclose a breeding space. The net is connected to the support rods. The pile legs have circumferentially oriented pin holes. The hydraulic lifting device includes a hydraulic cylinder and a pin. The hydraulic lifting device is connected to the columns. The pin of the hydraulic lifting device is inserted into the pin hole of the pile leg and can drive the pile leg to move up and down along the direction of the hydraulic cylinder. The cage structure relies on its own weight to press the pile legs into the soil for fixation.

[0005] In one embodiment, the pneumatic self-pressurized pile cage device further includes a ballast tank, a ballast water system, and a compressed air system. Each of the cofferdams is provided with a ballast tank. The ballast water system is used to inject water into the ballast tank, and the compressed air system is used to discharge the water from the ballast tank.

[0006] In one embodiment, the pneumatic self-pressurized pile cage device further includes a dissolved air tank. The ballast water system and the compressed air system are both connected to the dissolved air tank to form dissolved air water and store it in the dissolved air tank. The dissolved air tank is connected to the pile leg to output dissolved air water to the pile leg.

[0007] In one embodiment, each of the pile legs is provided with a barbed anchor plate, the barbed anchor plate including a connecting rod and a claw, one end of the claw being rotatably connected to the pile leg, and the two ends of the connecting rod being axially connected to the pile leg and the other end of the claw, respectively. The connecting rod is telescopically adjustable to open and close the claw so that the pile leg is fixed to the seabed.

[0008] In one embodiment, the pile leg is provided with a plurality of pin holes spaced vertically, and each pin hole is used to insert a pin to fix the pile leg to the pin hole.

[0009] In one embodiment, the pile leg is filled with concrete.

[0010] In one embodiment, the uprights and the support rods form a frame structure, and the support rods are interwoven to form a mesh structure connecting adjacent uprights, so as to surround the sides and bottom of the uprights to form the breeding space.

[0011] In one embodiment, a working platform is provided at the top of the support rod. The working platform includes a column area and a connecting area. The column area is located at the top of each column, and the connecting area is located at the top of the frame structure. The connecting area is provided with a connecting channel to connect two columns. The column area and the connecting area enclose a ring-shaped working platform. Guardrails are provided on both sides of the working platform. The hydraulic lifting device is located in the column area.

[0012] In one embodiment, the connecting areas on the left and right sides of the column area are provided with diagonal bracing at the horizontal corners, and a connecting channel is also provided above the diagonal bracing. At least one of the column areas is provided with a feed tank, and the feed tank is provided with a feeding pipe extending along the direction close to the center of the pneumatic self-pressurized pile net box device.

[0013] In one embodiment, the mesh includes a top mesh, side meshes, and a bottom mesh, with the top mesh connected to the top of the frame structure, the side meshes connected to the side walls of the frame structure, and the bottom mesh connected to the bottom of the frame structure.

[0014] This invention proposes a pneumatically operated self-pressurized piling cage device, belonging to the field of aquaculture equipment. It is suitable for large-scale fish farming in open waters such as oceans, providing a stable growth space for farmed aquatic products. Simultaneously, its adjustable height allows it to adapt to different aquatic environments and farming needs, ensuring the safety and efficiency of the farming process. The pneumatically operated self-pressurized piling cage device includes a cage structure, piling legs, and a hydraulic lifting device. The coordinated design of the cage structure and piling legs utilizes the weight of the cage structure itself to provide active driving force, improving the efficiency of piling leg insertion and fixation. Furthermore, it eliminates the need for additional piling boat assistance; the weight of the piling legs and cage structure alone is sufficient for piling, increasing efficiency and reducing costs. The farming space formed by the columns and supports provides a safe growth environment for aquatic products. The mesh's sealing and permeability balance escape prevention and water quality maintenance, while the precise control of the hydraulic lifting device ensures a smooth and controllable lifting process for the piling legs. This enhances the adaptability and safety of the pneumatically operated self-pressurized piling cage device in marine environments, making it suitable for long-term, large-scale aquaculture operations.

[0031] Cage aquaculture is currently the main method of marine fish farming, and it is increasingly attracting the attention of coastal countries around the world. With the development of marine aquaculture, pneumatically powered self-propelled piling cages are no longer limited to being submerged; they are required to achieve more functions through raising and lowering. For example, during daily aquaculture operations, they should be able to adapt to water level changes caused by tidal ranges, suspending at a certain draft depth, while floating during harvesting operations, and sinking to avoid disasters such as typhoons and red tides. Currently, the installation of existing pneumatically powered self-propelled piling cages typically requires the assistance of a piling vessel to insert the piling legs into the seabed to secure the cage and ensure its stability in the ocean. However, the cost of using a piling vessel for piling is high, increasing the overall cost of cage aquaculture.

[0032] To solve the above problems, please refer to... Figures 1 to 4 This invention proposes a pneumatic self-pressurized pile cage device 100, including a cage structure 1, pile legs 21, and a hydraulic lifting device 22. The cage structure 1 includes a column 11, a support rod 12, a surrounding well 13, and a net 14. The column 11 and the support rod 12 enclose a breeding space. The net 14 is connected to the support rod 12. The pile legs 21 have pin holes 21a along the circumference. The hydraulic lifting device 22 includes a hydraulic cylinder and a pin. The hydraulic lifting device 22 is connected to the column 11. The pin of the hydraulic lifting device 22 is inserted into the pin hole 21a of the pile legs 21 and can drive the pile legs 21 to move up and down along the direction of the hydraulic cylinder. The cage structure 1 relies on its own weight to press the pile legs 21 into the soil to achieve fixation.

[0033] The present invention proposes a pneumatically operated self-pressurized pile cage device 100, belonging to the field of aquaculture equipment. It is suitable for large-scale fish farming in open waters such as oceans, providing a stable growth space for farmed aquatic products. Simultaneously, it can be adjusted in height to adapt to different aquatic environments and farming needs, ensuring the safety and efficiency of the farming process. The pneumatically operated self-pressurized pile cage device 100 includes a cage structure 1, pile legs 21, and a hydraulic lifting device 22. The columns 11 and support rods 12 are made of high-strength marine steel, possessing high yield strength and good performance consistency. The overall enclosure forms a closed farming space, providing ample activity and growth area for aquatic products. In this embodiment, the pneumatic self-pressurized piling cage device 100 is a three-dimensional frame structure with a rectangular cross-section, formed by four columns 11 (C1-C4 in the figure) and multiple support rods 12. Each column 11 has a well 13 at its bottom, and each well 13 contains a ballast tank to ensure the uniformity of the overall buoyancy of the pneumatic self-pressurized piling cage device 100 at the four corners. In other embodiments, the pneumatic self-pressurized piling cage device 100 can also be a cylindrical structure or a cubic structure of other shapes, depending on the actual aquaculture needs. The netting 14 is made of high-strength polyethylene woven mesh or nylon mesh, which is wear-resistant and resistant to water flow impact. It is connected to the inside of the support rods 12 by binding or snapping, further sealing the aquaculture space and preventing the escape of aquatic products. The piling legs 21 are vertically fixed to the seabed using steel pipes, providing a stable support foundation for the entire pneumatic self-pressurized piling cage device 100. The cage structure 1 is connected to the pile leg 21 by the pin of the hydraulic lifting device 22. The inner diameter of the hydraulic lifting device 22 matches the outer diameter of the pile leg 21, ensuring that the cage structure 1 can move smoothly up and down along the extension direction of the pile leg 21.

[0034] The hydraulic lifting device 22 is a hydraulic cylinder or hydraulic push rod, located on the working platform 15 at the top of the column 11. The output end of the hydraulic lifting device 22 is connected to the pin hole on the pile leg 21 through the pin, which can drive the pile leg 21 to move vertically along its own extension direction.

[0035] The design of the mesh cage structure 1 and the pile legs 21 utilizes the weight of the mesh cage structure 1 itself to provide active driving force, while dissolved air water reduces the friction of the pile legs 21, significantly improving the efficiency and depth of the pile legs 21 insertion and fixing. This avoids the problem of unstable fixing caused by excessive resistance or insufficient insertion depth. Furthermore, no additional piling vessel is needed; the weight of the pile legs 21 and the mesh cage structure 1 is sufficient for pile driving, improving efficiency and reducing costs. The aquaculture space formed by the columns 11 and support rods 12 provides a safe growth environment for aquatic products. The mesh 14's sealing and permeability balance escape prevention and water quality maintenance, while the precise control of the hydraulic lifting device 22 ensures smooth and controllable lifting of the pile legs 21. This enhances the adaptability and safety of the pneumatic self-pressurizing pile mesh cage device 100 in marine environments, making it suitable for long-term, large-scale aquaculture operations.

[0036] In one embodiment, please refer to Figure 1 The pneumatic self-propelled pile gabion device 100 also includes a ballast tank, a ballast water system, and a compressed air system. Each cofferdam 13 has a ballast tank inside. The ballast water system is used to inject water into the ballast tank, and the compressed air system is used to discharge the water from the ballast tank. The pneumatic self-propelled pile gabion device 100 also includes a ballast tank, a ballast water system, and a compressed air system. Each column 11 has a cofferdam 13 (WBC1-WBC4 in the figure) at its bottom. The ballast water system is used to inject water into the buoyancy chamber inside the cofferdam 13, and the compressed air system is used to discharge the water from the ballast tank.

[0037] The ballast tank is a sealed metal box, bolted to the bottom of each column 11, forming an integrated structure with the column 11. Its interior forms a closed cavity for holding water. The ballast water system includes a ballast pump, an inlet pipeline, and an inlet control valve. The ballast pump is installed on the working platform 15 of the cofferdam 11. One end of the inlet pipeline connects to the outlet of the ballast pump, and the other end connects to the inlet of the ballast tank. The inlet control valve is connected in series on the inlet pipeline to control its operation. The ballast pump is a corrosion-resistant submersible pump or centrifugal pump, capable of directly drawing water from the aquaculture area and injecting it into the ballast tank without requiring an additional water supply. When it is necessary to increase the weight of the net cage to facilitate submersion, the inlet control valve and the ballast pump are opened, and water enters the ballast tank through the inlet pipeline. As the water volume increases, the overall weight of the ballast tank increases, and it moves downwards along the pile legs 21 under gravity.

[0038] The compressed air system includes a high-pressure air pump, a drainage pipeline, and a drainage control valve. The high-pressure air pump is also installed on the working platform 15, spaced apart from the ballast pump to avoid mutual interference. One end of the drainage pipeline is connected to the high-pressure air pump, and the other end is connected to the drain outlet of the ballast tank. By introducing air into the ballast tank, the water inside is discharged. The drain outlet is located at the bottom of the ballast tank to ensure that the water inside the tank can be completely discharged. The drainage control valve is connected in series with the drainage pipeline to control the opening and closing of the drainage pipeline. When the cage needs to float, the drainage control valve and the high-pressure air pump are opened. The high-pressure air pump discharges the water in the ballast tank back to the aquaculture area. The weight of the ballast tank is reduced, and it moves upward along the legs 21 under the action of buoyancy.

[0039] The ballast tank, ballast water system, and compressed air system work together to enable the cage structure 1 to rise and fall smoothly along the extension direction of the legs 21. The guiding function of the legs 21 ensures that the enclosure 11 does not deviate during raising and lowering. At the same time, the pin holes 21a and fasteners on the legs 21 can lock the cage in place after it reaches a preset depth, preventing accidental movement of the cage due to malfunctions in the ballast water system or compressed air system. This structural design does not rely on complex hydraulic equipment, achieving raising and lowering control through simple water circulation, reducing equipment costs and maintenance difficulty. Furthermore, it utilizes water from the aquaculture area as the ballast medium, eliminating the need for additional reserves and improving aquaculture safety and adaptability.

[0040] In one embodiment, please refer to Figure 1 , Figure 9 as well as Figure 10 The pile driving structure 2 also includes a dissolved air tank. The ballast water system and the compressed air system are both connected to the dissolved air tank to form dissolved air water for storage in the dissolved air tank. The dissolved air tank is connected to the pile leg 21 to output dissolved air water to the pile leg 21.

[0041] The dissolved air tank is a sealed stainless steel tank, fixed to the working platform 15 by a bracket. It forms a closed mixing chamber inside, and the inner wall of the tank is equipped with baffles to enhance the mixing effect of air and water. The top of the dissolved air tank has an air inlet and a water inlet, while the bottom has a dissolved air water outlet. The air inlet is connected to the pressure regulating valve of the compressed air system via an air pipe, and the water inlet is connected to a branch of the ballast water system's inlet pipe via a water pipe, thus creating a connection between the ballast water system and the compressed air system and the dissolved air tank. In this embodiment, the ballast water system is connected to the ballast tank and the compressed dissolved air tank via different pipe branches. This not only assists in the floating and submerging of the cage structure 1, but also helps generate dissolved air water to aid in pile driving and fixation, reducing the difficulty of inserting the pile legs 21 into the seabed. The water inlet of the ballast water system is located in the ballast tank and is funnel-shaped. Seawater is drawn in and filtered by the ballast pump and transported through pipelines to the dissolved air tank for treatment. When dissolved air water needs to be prepared, the ballast water system delivers the water from the aquaculture area to the dissolved air tank, while the compressed air system injects filtered compressed air into the dissolved air tank. The water and air are fully mixed in the tank by the action of the baffles to form dissolved air water containing tiny bubbles, which is then stored in the mixing chamber of the dissolved air tank.

[0042] When it is necessary to fix the pneumatic self-pressurized pile cage device 100, the cage structure 1 itself has a certain weight, which acts on the pile legs 21, exerting downward pressure on the pile legs 21. At the same time, the hydraulic lifting device 22 is activated, and its output end pushes the pile legs 21 downward, causing the pile legs 21 to move towards the seabed; at the same time, dissolved air water in the dissolved air tank is injected into the dissolved air water pipe at the bottom of the pile legs 21. A drain hole is opened on the dissolved air water pipe near the bottom of the pile legs 21, and the dissolved air water will drain from the drain hole. The air in the dissolved air water will be released in the form of bubbles. The bubbles will wrap around the outer wall of the pile legs 21, reducing the friction between the pile legs 21 and the soil, so that the pile legs 21 can overcome the resistance of the seabed and insert into the soil faster and deeper. Once the pile leg 21 is inserted to the preset depth, the hydraulic lifting device 22 stops operating, and the pile leg 21 is tightly connected to the seabed, thus fixing the pile structure 2 and the entire cage. If it is necessary to adjust the position of the cage or retrieve the pile leg 21, the output end of the hydraulic lifting device 22 pulls the pile leg 21 upward and reduces the weight of the cage structure 1, such as by discharging some water to reduce the pressure on the pile leg 21. At the same time, the dissolved air tank injects water into the dissolved air pipe on the pile leg 21 again, so that the pile leg 21 can be pulled out smoothly.

[0043] The combined use of the compressed air system, dissolved air tank, and ballast water system expands the functionality of the pile driving structure 2. The ballast water system provides a stable water source for the dissolved air tank, while the compressed air system provides high-pressure air; together, they prepare dissolved air water. After being injected into the pile legs 21, the dissolved air water acts on the seabed, solving the problem of difficult insertion of the pile legs 21 in hard seabeds. Simultaneously, the fixing depth of the pile legs 21 can be flexibly adjusted to adapt to waters with different geological conditions. This structural design makes the pile driving structure 2 more adaptable, not only achieving foundation fixation through the pile legs 21 but also ensuring the stability of the pile legs 21 fixed to the seabed. This further enhances the overall anti-overturning capacity and stability of the pneumatic self-pressurized pile gabion device 100, ensuring safe operation of the pneumatic self-pressurized pile gabion device 100 in complex geological and water environments.

[0044] In one embodiment, please refer to Figure 7 and Figure 8 Each leg 21 is provided with a barbed anchor plate 211. The barbed anchor plate 211 includes a connecting rod 2111 and a claw 2112. One end of the claw 2112 is rotatably connected to the leg 21. The two ends of the connecting rod 2111 are respectively connected to the other end of the leg 21 and the claw 2112. The connecting rod 2111 can be extended and retracted to realize the opening and closing of the claw 2112 so that the leg 21 is fixed to the seabed.

[0045] Each leg 21 is equipped with a barbed anchor plate 211, which includes a connecting rod 2111 and a claw 2112. The claw 2112 is a metal claw-shaped structure, with one end rotatably connected to the lower part of the leg 21 via a pivot, and can rotate around the pivot in a horizontal or vertical direction. The connecting rod 2111 is a telescopic hydraulic rod, with its two ends axially connected to the middle of the leg 21 and the other end of the claw 2112 via hinges. When the leg 21 is inserted into the seabed, the connecting rod 2111 is extended, pushing the claw 2112 to open around the pivot, and the tip of the claw 2112 inserts into the soil of the seabed, forming an anchoring structure. When it is necessary to disassemble the leg 21, the connecting rod 2111 is retracted, pulling the claw 2112 to close around the pivot, thus detaching it from the seabed. The barbed anchor plate 211 enhances the fixing strength between the pile leg 21 and the seabed, preventing the pile leg 21 from tilting or shifting under the action of water flow, wind and waves or the weight of the net cage, ensuring the stability of the pile structure 2, and providing a reliable support foundation for the lifting and lowering of the net cage and aquaculture. It is especially suitable for waters with soft seabed soil and improves the net cage's anti-overturning ability.

[0046] In one embodiment, please refer to Figure 5 and Figure 6 The pile leg 21 has multiple pin holes 21a spaced vertically, and each pin hole 21a is used to insert a pin to fix the pile leg 21 to the pin hole 21a.

[0047] The pile leg 21 has multiple pin holes 21a spaced vertically. Each pin hole 21a is a through hole penetrating the side wall of the pile leg 21, and its diameter matches the size of the pin. When the enclosure 11 is raised or lowered to a preset depth, a pin is inserted into the corresponding pin hole 21a. One end of the pin extends out of the side wall of the pile leg 21 and abuts against the sliding collar of the hydraulic lifting device 22, limiting the relative position of the hydraulic lifting device 22 and the pile leg 21, thereby limiting the installation position of the cage structure 1 on the pile leg 21. The spacing of the multiple pin holes 21a provides multiple fixed positions for the cage structure 1, allowing for selection of a suitable depth for fixing according to aquaculture needs. This ensures that the cage structure 1 remains stably at that depth, preventing accidental raising or lowering of the enclosure 11 due to water flow impact or equipment malfunction. The insertion method of the pin is convenient and does not require complicated tools. Aquaculture personnel can quickly complete the fixing and unlocking. At the same time, the matching structure between the pin hole 21a and the pin is simple and reliable, with strong load-bearing capacity, which can effectively resist the lateral force of the net cage structure 1 and ensure the stability of the net cage structure 1 during the aquaculture process.

[0048] In one embodiment, the pile leg 21 is filled with high-strength, corrosion-resistant concrete, which is poured into the hollow interior of the pile leg 21, filling its entire length. The concrete filling increases the weight of the pile leg 21, allowing it to be more stably fixed after being inserted into the seabed, less prone to swaying due to wind, waves, or currents. Simultaneously, the rigidity of the concrete enhances the structural strength of the pile leg 21, preventing bending deformation due to corrosion or impact during long-term use. The combined structure of concrete and the metal shell of the pile leg 21 combines the corrosion resistance of metal with the rigidity of concrete, extending the service life of the pile leg 21. This is particularly suitable for harsh environments such as deep seas, ensuring the long-term stability and reliability of the pile structure 2 and providing durable support for the gabion.

[0049] Furthermore, in one embodiment, please refer to Figure 5 and Figure 6 The columns 11 and the support rods 12 form a frame structure. The support rods 12 are interwoven to form a mesh structure that connects the two adjacent columns 11 to surround the sides and bottom of the columns 11 to form a breeding space.

[0050] The uprights 11, made of hollow steel pipes, are evenly distributed around the outer perimeter of the cage structure 1, forming the main supporting framework with sufficient strength to withstand the impact of water flow and waves. Multiple support rods 12 of the frame structure are high-strength metal rods, welded together in a crisscross pattern to form a mesh structure. These rods connect adjacent uprights 11, surrounding not only the sides of the uprights 11 but also covering their bottoms, collectively enclosing a complete aquaculture space. The frame structure not only provides a foundation for the installation of the netting 14, ensuring stable and reliable installation on both the sides and bottom, but also helps improve the overall rigidity of the cage structure 1, preventing deformation of the enclosure 11 due to water flow impact or aquatic product activity. The welded connection between the uprights 11 and the ribs ensures the integrity and stability of the enclosure 11 structure. The mesh structure, while maintaining strength, reduces water flow resistance, preventing excessive lateral thrust on the cage in the water, ensuring smooth lifting and lowering, and providing ample space for aquatic products to move around without affecting their normal growth.

[0051] In another embodiment, please refer to Figures 1 to 4 The top of the support rod 12 is provided with a working platform 15. The working platform 15 includes a column area 15a and a connecting area 15b. The column area 15a is located at the top of each column 11, and the connecting area 15b is located at the top of the frame structure. The connecting area 15b is provided with a connecting channel to connect the two columns 11. The column area 15a and the connecting area 15b enclose and form a ring-shaped working platform 15. Guardrails are provided on both sides of the working platform 15. The hydraulic lifting device 22 is located in the column area 15a.

[0052] A working platform 15 is located at the top of the enclosure 11. The working platform 15 is constructed of anti-slip steel plates welded to a steel structural frame and is divided into a column area 15a and a connecting area 15b. Column areas 15a are located at the top of each column 11 and are bolted to form an independent operating platform. Connecting areas 15b are located at the top of the frame structure and are welded to adjacent column areas 15a, providing anti-slip connecting channels to allow communication between adjacent columns 11. The column areas 15a and connecting areas 15b together form a ring-shaped working platform 15, surrounding the top of the entire enclosure 11, facilitating inspection, feeding, and harvesting operations for aquaculture personnel throughout the entire cage area. Guardrails are installed on both sides of the working platform 15. These guardrails are constructed of welded metal tubing and meet safety standards, effectively preventing aquaculture personnel from accidentally falling into the water, especially in windy and wavery weather, providing a safe operating environment. The work platform 15 provides a convenient operating space for aquaculture operations. The ring structure ensures that personnel can reach any position in the net cage, while the guardrail ensures the safety of operations and improves the efficiency and reliability of aquaculture management.

[0053] In one embodiment, please refer to Figure 4The connecting area 15b around the column area 15a has a diagonal brace 15c at the horizontal corner, and a connecting channel is also provided above the diagonal brace 15c. At least one column area 15a has a feed tank 151, and the feed tank 151 extends along the direction close to the center of the pneumatic self-pressurized pile net box device 100 with a feeding pipe 151a.

[0054] At the horizontal corner of the column area 15a and the connecting area 15b, there is a diagonal brace 15c. The diagonal brace 15c is a metal triangular plate or square tube, which is fixed to the inside of the corner by welding to enhance the structural strength of the corner and prevent the corner from deforming due to personnel movement or equipment placement. A connecting passage is also provided above the diagonal brace 15c to make the passage of the working platform 15 more continuous and avoid passage obstruction at the corner. At least one column area 15a is provided with a feed tank 151. The feed tank 151 is a sealed metal tank, which is fixedly installed on the platform of the column area 15a for storing aquaculture feed. The feed tank 151 extends along the direction close to the center of the pneumatic self-pressurized pile net cage device 100 and is provided with a feeding pipe 151a. The feeding pipe 151a is a rigid plastic or metal pipe, through which feed is transported from the feed tank 151 to the net cage structure 1 below for feeding. In this embodiment, the pneumatic self-pressurizing pile cage device 100 has two feeding zones, which are diagonally distributed along the pneumatic self-pressurizing pile cage device 100. Each feeding zone is equipped with a feeding pipe 151a to realize the feeding operation. The setting of the diagonal brace 15c improves the overall rigidity of the working platform 15, ensuring that the platform can support the weight of equipment such as the feed tank 151; the continuous connecting channel facilitates personnel to move feed or equipment; the cooperation between the feed tank 151 and the feeding pipe 151a realizes automatic or semi-automatic feeding. The feed is evenly scattered into the breeding space through the discharge port of the feeding pipe 151a, ensuring that aquatic products can obtain feed evenly, avoiding uneven growth caused by competition for food, while reducing feed waste and improving breeding efficiency.

[0055] In one embodiment, the mesh 14 includes a top mesh, side meshes, and a bottom mesh. The top mesh is connected to the top of the frame structure, the side meshes are connected to the side walls of the frame structure, and the bottom mesh is connected to the bottom of the frame structure.

[0056] The top, side, and bottom nets are made of the same material, such as high-strength polyethylene woven mesh or nylon mesh. The top net is attached to the top of the frame structure with clips or ties, covering the entire top of the aquaculture space to prevent predators like birds from preying on the aquatic products and to prevent them from escaping when the cages are submerged. The side nets are attached to the side walls of the frame structure with clips or ties, surrounding the aquaculture space and further preventing the escape of aquatic products and the entry of foreign debris. The bottom net is attached to the bottom of the frame structure with clips or ties, sealing off the lower part of the aquaculture space to prevent aquatic products from diving to the seabed or being attacked by underwater creatures. The top, side, and bottom nets are stitched together with ropes or spliced ​​with clips to form a completely enclosed aquaculture space. The overall structure ensures the safety and integrity of the aquaculture space while not affecting water exchange and maintaining the freshness of the water quality in the aquaculture area. In this embodiment, the side netting and bottom netting are assembled from multiple units. The frame structure of the well 11 is formed by multiple ribs crisscrossing to create a mesh structure with multiple grids. Each grid is connected to a piece of mesh fabric, and multiple pieces of mesh fabric are spliced ​​together to form the overall side netting and bottom netting. This design further improves the stability of the mesh 14 connection. By connecting individual pieces of mesh fabric to the grid around their perimeter, the number of stress points for the mesh fabric connection is increased, making the connection between the mesh fabric and the frame structure more reliable. In addition, the design of the mesh fabric units also facilitates the subsequent maintenance and replacement of the mesh 14. For example, when a part of the mesh 14 is damaged, only that individual piece of mesh fabric needs to be repaired or replaced, without needing to adjust the entire mesh 14, thus improving the flexibility and convenience of maintenance.

[0057] In one embodiment, the column area 15a also includes a generator room and power generation equipment. The generator room is a sealed metal enclosure, fixedly installed on the platform of the column area 15a. The interior can accommodate the control module, energy storage battery, and other components of the power generation equipment, providing protection against wind, rain, or seawater corrosion. The power generation equipment is installed at the top of the generator room and can be a wind turbine or photovoltaic panel, selected according to the environmental conditions of the aquaculture area. The power generation equipment is connected to the energy storage battery and control module in the generator room via wires, providing power to the hydraulic lifting equipment 22, feeding equipment, lighting equipment, monitoring equipment, etc., of the net cage. The generator room provides protective space for the auxiliary components of the power generation equipment, extending its service life. The integration of the power generation equipment enables the pneumatic floating self-pressurized pile net cage device 100 to achieve energy self-sufficiency, eliminating reliance on an external power grid. This is particularly suitable for aquaculture scenarios in remote waters, reducing power transmission costs while ensuring the stable operation of various equipment and improving the intelligence and automation level of the pneumatic floating self-pressurized pile net cage device 100.

[0058] The following is a detailed explanation of the pile driving principle of the pneumatic self-pressurized pile gabion device 100 in this embodiment: In the initial state, the pneumatic self-propelled gabion assembly 100 is not yet fixed to the seabed. An airbag is installed at the bottom of the assembly, and the buoyancy of the airbag moves the assembly to the designated sea area for installation. At this time, the pile legs 21 are in a retracted state relative to the column 11, and the column 11 is fixed to the lowermost pin hole 21a of the pile leg 21. Under the action of the hydraulic lifting device 22, the pile legs 21 gradually descend. When the pile legs 21 move to a certain depth into the seabed, they lift the gabion structure 1 under the action of the seabed. At this time, the pile legs 21 exert a supporting force on the gabion structure 1, and correspondingly, the gabion structure 1 exerts a downward pressure on the pile legs 21. The weight of the gabion structure 1 presses down on the pile legs 21, causing them to continue extending into the seabed. During this process, water can also be injected into the ballast tank to increase the weight of the gabion structure 1. The weight of the pile legs 21 and the gabion structure 1 together achieves pile sinking. Once the pile legs 21 are inserted into the seabed to the predetermined depth, the barbed anchor plates 211 on the pile legs 21 are opened, firmly fixing the pile legs 21 to the seabed. At this point, the airbags at the bottom of the gabion structure 1 can be removed, completing the pile driving and fixing of the pneumatic self-pressurized pile gabion device 100. In this scheme, the pneumatic self-pressurized pile gabion device 100 achieves pile driving and fixing through the self-weight of the pile legs 21 and the gabion structure 1, eliminating the need for a pile driving vessel to assist in pile driving and reducing the cost of pile driving and fixing of the pneumatic self-pressurized pile gabion device 100. In addition, by pouring concrete into the pile legs 21 to increase their weight and achieve the sinking effect, and in conjunction with the barbed anchor plates 211 on the pile legs 21 to improve the pull-out resistance of the pile legs 21, the stability of the pile legs 21 is further improved, thereby ensuring the stability of the pneumatic self-pressurized pile gabion device 100. The cage structure 1 floats and submerges through the ballast tank at the bottom of the column 11, which improves the typhoon resistance of the cage structure 1 and enhances the overall safety and reliability.
