Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and in particular to an independent lifting aquaculture cage that is easy to tow and its usage method. Background Technology

[0002] Aquaculture cages, used in marine aquaculture, offer advantages such as vast sea areas, resource conservation, superior water quality, and convenient management, making them a highly efficient, environmentally friendly, and economical method of aquaculture. Marine aquaculture cages typically require tugboats to be towed to suitable aquaculture areas before installation. Before towing, the cages are usually placed on a buoyancy platform made of steel plates, and fasteners are used to connect the cages to the platform. Alternatively, fasteners can be used to connect the cages to pontoons to provide buoyancy for towing. However, because the cages are large pieces of equipment, placing them on the buoyancy platform requires significant lifting equipment. Furthermore, the cages need to be dismantled from the pontoons or platform upon reaching the designated location, impacting towing and installation efficiency. The fasteners used to connect the cages to the pontoons or platform are prone to corrosion in marine environments, leading to unstable connections. In addition, existing net cages are usually large single cages, making it impossible to manage individual sections of the cultured organisms within them. Summary of the Invention

[0003] In response to the problems raised in the background art, the purpose of this invention is to provide an independently lifting aquaculture cage that is easy to tow, without the need to disassemble or assemble the pontoon or buoyancy platform. This effectively improves towing efficiency and cage installation efficiency at designated locations, and effectively ensures the structural stability of the towed objects during towing. The cage frame can be independently lifted and lowered, facilitating operation and maintenance. This solves the problems of unstable connection, low towing efficiency, and low cage installation efficiency caused by the need to disassemble or assemble the pontoon or buoyancy platform for towing existing cages, as well as the technical problem of not being able to operate a certain part of the aquaculture in the cage individually.

[0004] Another objective of this invention is to provide a method for using an independently lifting aquaculture cage that is easy to tow, convenient to operate, capable of lifting the aquaculture cage individually, and easy to maintain.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] An independent lifting aquaculture cage that is easy to tow, comprising at least one aquaculture cage module, wherein the aquaculture cage module includes a buoyancy truss, at least two cage frames and multiple pile legs, wherein the buoyancy truss includes multiple first buoyancy frames and at least one second buoyancy frame, and the multiple first buoyancy frames are connected end to end to form a closed structure with an internal space;

[0007] The second buoyancy frame is connected between two oppositely arranged first buoyancy frames to divide the internal space into at least two cage installation spaces. The cage frame can be independently raised and lowered within the cage installation space, and the cage frame and the cage installation space are arranged in a one-to-one correspondence.

[0008] The pile legs are vertically and vertically mounted on the first buoyancy frame.

[0009] The first buoyancy frame and the second buoyancy frame are respectively provided with a receiving cavity, which is used to place the buoyancy body.

[0010] To further clarify, the number of aquaculture cage modules is multiple, and the multiple aquaculture cage modules are arranged side by side.

[0011] Furthermore, the aquaculture cage module also includes a first lifting drive mechanism and a second lifting drive mechanism, which are respectively disposed on the first buoyancy frame.

[0012] The drive end of the first lifting drive mechanism is connected to the pile leg in a transmission connection, and the first lifting drive mechanism drives the pile leg to move up and down relative to the buoyancy truss.

[0013] The drive end of the second lifting drive mechanism is connected to the mesh cage frame, and the second lifting drive mechanism drives the mesh cage frame to move up and down relative to the buoyancy truss.

[0014] To further explain, the first buoyancy frame and the second buoyancy frame have the same structure. The first buoyancy frame includes multiple first support rods and multiple first connecting rods. The first support rods are arranged parallel to each other in the horizontal and vertical directions. The first connecting rods are connected between two adjacent first support rods, and the first connecting rods are arranged in pairs to make the first buoyancy frame form a mesh frame structure. The first support rods and the first connecting rods enclose the cavity.

[0015] The cage frame includes multiple lifting rods, multiple second support rods, and multiple second connecting rods. The multiple lifting rods are arranged parallel to each other in the vertical direction, and the multiple second support rods are arranged parallel to each other in the horizontal direction. The second support rods are connected between two adjacent lifting rods, and the second connecting rods are connected between two oppositely arranged second support rods. The second connecting rods are arranged in pairs to make the cage frame form a mesh frame structure.

[0016] The drive end of the second lifting drive mechanism is connected to the lifting rod via a transmission.

[0017] To further explain, the upper end face of the lifting rod is at a higher horizontal level than the upper end face of the second support rod.

[0018] To further explain, the multiple pile legs are respectively located at the corners of the closed structure formed by the first buoyancy frame.

[0019] Furthermore, the buoyancy truss also includes multiple fixed pile seats. The fixed pile seats are provided at the corners of the closed structure formed by the first buoyancy frame body. The fixed pile seats have through holes in the vertical direction, and the pile legs pass through the through holes and are slidably connected to the fixed pile seats.

[0020] To further clarify, the buoyancy body is a foam block or an air bladder.

[0021] A method for using a towable, independently adjustable aquaculture cage, comprising at least one of the following steps:

[0022] The independent lifting aquaculture cage is towed to a designated location: In the initial state, the horizontal plane where the lower end face of the pile leg is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss is located, and the horizontal plane where the lower end face of the cage frame is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss is located, so that the buoyancy truss is located at the bottom of the independent lifting aquaculture cage, and the independent lifting aquaculture cage is towed to a designated location;

[0023] Installation of the independent lifting aquaculture cage at a designated location: After the independent lifting aquaculture cage is towed to the designated location, the legs are lowered and fixed, the netting is installed on the cage frame, and the cage frame is lowered so that part of the cage frame is below the horizontal plane;

[0024] The independent lifting of the cage frame in the independent lifting aquaculture cage: the cage frame is raised above the horizontal plane, and each cage frame is operated and maintained independently.

[0025] To further explain, the method of using the aforementioned easy-to-tow independent lifting aquaculture cage also includes the following steps:

[0026] The second support rod is lowered below the horizontal plane, and the buoyancy truss is raised relative to the pile leg so that the entire buoyancy truss is completely above the horizontal plane;

[0027] Alternatively, the buoyancy body can be removed, and both the buoyancy truss and the cage frame can be lowered relative to the pile legs, so that the entire buoyancy truss and the cage frame are completely below the horizontal plane.

[0028] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0029] 1. Because the buoyancy body is located within the buoyancy truss, it can provide buoyancy greater than the self-weight of the independent lifting aquaculture cage. This allows the cage to be directly towed to a designated location without the need to disassemble the pontoon or buoyancy platform, making operation convenient and effectively improving towing efficiency and cage installation efficiency at the designated location. Furthermore, since the buoyancy truss is part of the structure of the independent lifting aquaculture cage, the cage relies on its own buoyancy truss for buoyancy during towing, effectively ensuring the structural stability of the towed object. This avoids the problem of unstable connections that arise when the cage needs to be connected to the pontoon or buoyancy platform via fasteners and then disassembled at the designated location, thus affecting towing efficiency. It also solves the problem of low cage installation efficiency caused by the need to disassemble the pontoon or buoyancy platform at the designated location.

[0030] 2. Because the net cage frames can be raised and lowered independently, different net cage frames within the aquaculture net cage module can be controlled independently, enabling zoned raising and lowering and individual operation. For example, when only a portion of the fish needs to be harvested, collected, separated, or replaced, a single net cage frame can be raised above the horizontal level, while the other net cage frames remain in the aquaculture stage. Furthermore, it facilitates maintenance operations on individual net cage frames. For instance, if only the netting on a specific net cage frame needs maintenance or replacement, simply raising that frame will suffice.

[0031] 3. The buoyancy truss can serve as a standing platform, allowing operators to stand on its upper surface for operations. Existing net cages cannot provide a standing position for operators; the nets must be raised and left to dry for a sufficient period before the operator can use a small boat to reach the adjacent net cage to set up a ladder for maintenance, or the nets can be retrieved and returned to the dock for cleaning. This independent lifting aquaculture net cage allows these maintenance operations to be performed directly at the installation location. Attached Figure Description

[0040] The components include: aquaculture cage module 1, buoyancy truss 2, first buoyancy frame 21, first support rod 211, first connecting rod 212, second buoyancy frame 22, accommodating cavity 23, fixed pile base 24, cage frame 3, lifting rod 31, second support rod 32, second connecting rod 33, pile leg 4, and cage installation space 5. Detailed Implementation

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0043] like Figure 1As shown, an independent lifting aquaculture cage that is easy to tow includes at least one aquaculture cage module 1. The aquaculture cage module 1 includes a buoyancy truss 2, at least two cage frames 3 and multiple pile legs 4. The buoyancy truss 2 includes multiple first buoyancy frames 21 and at least one second buoyancy frame 22. The multiple first buoyancy frames 21 are connected end to end to form a closed structure with an internal space.

[0044] The second buoyancy frame 22 is connected between two oppositely arranged first buoyancy frames 21 to divide the internal space into at least two cage installation spaces 5. The cage frame 3 can be independently raised and lowered in the cage installation space 5, and the cage frame 3 and the cage installation space 5 are arranged in a one-to-one correspondence.

[0045] The pile leg 4 is vertically and vertically mounted on the first buoyancy frame 21;

[0046] The first buoyancy frame 21 and the second buoyancy frame 22 are respectively provided with a receiving cavity 23, which is used to place the buoyancy body.

[0047] By setting up the buoyancy truss 2, and with the pile legs 4 vertically and flexibly mounted on the first buoyancy frame 21, the cage frame 3 can be independently vertically and flexibly mounted within the corresponding cage installation space 5. Figure 2 As shown, in the initial state, the horizontal plane where the lower end face of the pile leg 4 is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss 2 is located, and the horizontal plane where the lower end face of the net cage frame 3 is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss 2 is located, so that the buoyancy truss 2 is located at the bottom of the independent lifting aquaculture net cage. Since the buoyancy body is placed in the accommodating cavity of the first buoyancy frame 21 and the second buoyancy frame 22, the buoyancy truss 2, as part of the structure of the independent lifting aquaculture net cage, constitutes the "buoyancy platform" at the bottom of the independent lifting aquaculture net cage.

[0048] When it is necessary to tow the independent lifting aquaculture cage to a designated location in the sea, the independent lifting aquaculture cage is slid into the water via a slipway, and a tugboat is used to connect to the independent lifting aquaculture cage via a cable to tow the independent lifting aquaculture cage to the designated location. Due to the presence of the buoyancy body, it can provide buoyancy greater than the self-weight of the independent lifting aquaculture cage, facilitating direct towing of the cage to a designated location without disassembling the pontoon or buoyancy platform. This simplifies operation, effectively improves towing efficiency and cage installation efficiency at the designated location. Furthermore, since the buoyancy truss 2 is part of the structure of the independent lifting aquaculture cage, it provides buoyancy during towing, ensuring the structural stability of the towed object. This avoids the instability caused by fasteners connecting the cage to the pontoon or buoyancy platform, which would require disassembly at the designated location, thus affecting towing efficiency. It also solves the problem of low cage installation efficiency due to the need to disassemble the pontoon or buoyancy platform at the towing location.

[0049] After the independent lifting aquaculture cage is towed to the designated location, the legs 4 descend and insert into the seabed mud. The weight of the buoyancy truss 2 and the cage frame 3 provides support for the legs 4 after they are inserted into the mud, making the independent lifting aquaculture cage more stable at sea. Then, netting is installed on the cage frame 3, creating an aquaculture space where fish or other aquatic organisms can be placed. At this time, the cage frame 3 descends, partially submerging below the waterline. This independent lifting aquaculture cage does not require pre-installed netting, thus eliminating the need for wet towing and avoiding the problem of high water resistance caused by the netting during towing, effectively improving towing efficiency. Figure 1 As shown, the independent lifting aquaculture cage is in normal use at this time. Preferably, the cage frame 3 can be lowered to the middle position of the buoyancy truss 2, where the horizontal plane of its upper end is located.

[0050] Furthermore, since the net cage frame 3 can be independently raised and lowered, different net cage frames 3 in the aquaculture net cage module 1 can be independently controlled, achieving zoned raising and lowering and individual operation. For example, when only a portion of the fish needs to be caught, collected, separated, or exchanged, a single net cage frame 3 can be raised above the horizontal plane. Figure 3 As shown, the other cage frames 3 are still in the aquaculture stage at this time. Furthermore, it facilitates maintenance of a specific cage frame 3; for example, if only maintenance or replacement of the netting on a particular cage frame 3 is needed, the cage frame 3 can be raised.

[0051] To further explain, once the entire breeding cycle is completed, such as Figure 4 As shown, all the cage frames 3 can be raised above the horizontal plane, allowing for long-term maintenance of the cage frames 3. The buoyancy truss 2 can serve as a standing platform, allowing operators to stand on its upper surface for operations. Existing cages cannot provide a standing position for operators; the netting must be raised and left to dry for a sufficient period before the operator uses a small boat to reach the adjacent cage and use a ladder for maintenance, or the netting must be retrieved and returned to the dock for cleaning. This independent lifting aquaculture cage allows these maintenance operations to be performed directly at the installation location.

[0052] The independently lifting aquaculture cage facilitates towing operations without the need to disassemble or assemble the pontoon or buoyancy platform, effectively improving towing efficiency and cage installation efficiency at designated locations. It also effectively ensures the structural stability of the towed objects during towing. The cage frame 3 can be independently lifted and lowered, facilitating operation and maintenance. This solves the problems of unstable connections, low towing efficiency, and low cage installation efficiency caused by the need to disassemble or assemble the pontoon or buoyancy platform for existing cage towing, as well as the technical problem of not being able to operate on a specific part of the aquaculture within the cage.

[0053] like Figure 5 As shown, in another embodiment of this utility model, the number of aquaculture cage modules 1 is multiple, and the multiple aquaculture cage modules 1 are arranged side by side.

[0054] By setting up multiple aquaculture cage modules 1 and arranging them side by side, the multiple aquaculture cage modules 1 form an integrated independent lifting aquaculture cage, which greatly enhances the typhoon resistance of the independent lifting aquaculture cage, enabling high-density aquaculture and facilitating centralized management. Each cage frame 3 in each aquaculture cage module can be raised and lowered independently, facilitating independent processing of the aquatic products within each cage frame 3 (such as harvesting, handling, and separating fish), and simplifying maintenance of each individual cage frame 3.

[0055] Specifically, there are two cage frames 3 and one second buoyancy frame 22;

[0056] The second buoyancy frame 22 is disposed in the middle of the closed structure formed by the first buoyancy frame 21, so as to divide the internal space into two cage installation spaces 5 symmetrically arranged with respect to the second buoyancy frame 22, and the two cage frames 3 are respectively disposed in the corresponding cage installation spaces 5.

[0057] Specifically, the aquaculture cage module 1 is provided with three cages. Each cage frame 3, after the mesh is installed, can form a closed aquaculture space with a water volume of 10,000 cubic meters. When there are three aquaculture cage modules 1, and each aquaculture cage module 1 has two cage frames 3, the independently lifting aquaculture cage has a total aquaculture space of 60,000 cubic meters of water. The six 10,000 cubic meter aquaculture spaces can be independently lifted and lowered in separate zones, effectively realizing the independent lifting and lowering of small water bodies. It is not necessary to operate the 60,000 cubic meter aquaculture space at the same time; it is only necessary to operate the different aquaculture spaces independently as needed.

[0058] Furthermore, the aquaculture cage module 1 also includes a first lifting drive mechanism and a second lifting drive mechanism, which are respectively disposed on the first buoyancy frame 21;

[0059] The drive end of the first lifting drive mechanism is connected to the pile leg 4 in a transmission connection, and the first lifting drive mechanism drives the pile leg 4 to move up and down relative to the buoyancy truss 2.

[0060] The drive end of the second lifting drive mechanism is connected to the mesh box frame 3, and the second lifting drive mechanism drives the mesh box frame 3 to move up and down relative to the buoyancy truss 2.

[0061] By setting the first lifting drive mechanism and the second lifting drive mechanism, it is possible to drive the pile leg 4 to move up and down relative to the buoyancy truss 2, and to drive the cage frame 3 to move up and down relative to the buoyancy truss 2, which facilitates the control of the lifting position of the pile leg 4 and the lifting position of the cage frame 3.

[0062] like Figure 6 and Figure 7As shown, and further explained, the first buoyancy frame 21 and the second buoyancy frame 22 have the same structure. The first buoyancy frame 21 includes multiple first support rods 211 and multiple first connecting rods 212. The first support rods 211 are arranged parallel to each other in the horizontal and vertical directions. The first connecting rods 212 are connected between two adjacent first support rods 211, and the first connecting rods 212 are arranged in pairs to form a mesh frame structure of the first buoyancy frame 21. The first support rods 211 and the first connecting rods 212 enclose the receiving cavity 23. By setting the first support rods 211 and the first connecting rods 212, the first support rods 211 can provide horizontal support force, and the first connecting rods 212 can provide reinforcement for the first buoyancy frame 21 and the second buoyancy frame 22. The first support rods 211 and the first connecting rods 212 enclose the receiving cavity 23 to place the buoyancy body.

[0063] The cage frame 3 includes multiple lifting rods 31, multiple second support rods 32, and multiple second connecting rods 33. The lifting rods 31 are arranged parallel and spaced apart in the vertical direction, and the second support rods 32 are arranged parallel and spaced apart in the horizontal direction. The second support rods 32 are connected between two adjacent lifting rods 31, and the second connecting rods 33 are connected between two oppositely arranged second support rods 32. The second connecting rods 33 are arranged in pairs to form a mesh frame structure for the cage frame 3. By setting the second support rods 32 and the second connecting rods 33, the cage frame 3 can be supported and can be fitted with mesh panels, so that the cage frame 3 can be enclosed to form a breeding space after the mesh panels are installed.

[0064] The drive end of the second lifting drive mechanism is connected to the lifting rod 31. The lifting rod 31 can be connected to the second lifting drive mechanism to realize the lifting and lowering of the wire mesh frame 3, and to fix the position of the wire mesh frame 3 after lifting and lowering.

[0065] Specifically, four first support rods 211 are provided, arranged in a rectangular shape with parallel spacing. Between two adjacent first support rods 211, multiple intersecting first connecting rods 212 are arranged along the length of the first support rods 211, so that the first buoyancy frame 21 and the second buoyancy frame 22 form a mesh frame structure. The first buoyancy frame 21 can also be obtained by splicing multiple sections. Multiple sections of the mesh frame structure can be prefabricated and transported to the slipway for assembly at the final assembly site. Since the overall volume of the buoyancy truss 2 structure is very large, transporting and installing it in multiple modules can facilitate transportation, save transportation costs, and the modular assembly can effectively improve assembly efficiency and save assembly time.

[0066] Specifically, longitudinal racks can be provided on both sides of the pile leg 4 and on both sides of the lifting rod 21. The first lifting drive mechanism and the second lifting drive mechanism have the same structure. The first lifting drive mechanism adopts a structure in which a motor is connected to a reduction gearbox to drive the gear to rotate. The gear meshes with the rack on the corresponding pile leg 4 or with the rack on the corresponding lifting rod 31. When the gear rotates, it drives the pile leg 4 to move up and down, and the gear rotates to drive the lifting rod 31 to move up and down.

[0067] Specifically, six legs 4 are provided. One leg 4 is provided at each corner of the closed structure formed by the first buoyancy frame 21, and the second buoyancy frame 22 is provided with legs 4 corresponding to the first buoyancy frame 21. By also providing legs 4 on the second buoyancy frame 22 corresponding to the first buoyancy frame 21, the supporting stability of the buoyancy truss 2 can be improved, thereby improving the installation stability of the independent lifting aquaculture cage in the sea and effectively enhancing its resistance to typhoon disasters.

[0068] To further explain, the second lifting drive mechanism located in the middle (that is, at the location corresponding to the second buoyancy frame 22) can also be disposed on the surface of the second buoyancy frame 22.

[0069] Specifically, the upper end face of the lifting rod 31 is at a higher horizontal level than the upper end face of the second support rod 32. This causes the length of the lifting rod 31 to protrude beyond the upper end face of the second support rod 32. When it is necessary to lower the net below the water surface, the lifting rod 31 can provide a greater descent distance, allowing the second support rod 32 to descend to a certain depth below the water surface. For example, when a typhoon arrives, the second support rod 32 can be lowered to a certain depth below the water level (e.g., 8 meters below the water surface), so that the aquaculture space enclosed by the netting is completely lowered below the water level. At the same time, the buoyancy truss 2 is raised a certain distance relative to the pile leg 4 (since the pile leg 4 is already inserted into the mud, its height will not change, but the position of the buoyancy truss 2 relative to the pile leg 4 will change). At this time, the entire buoyancy truss 2 is completely above the water level. With the weight of the buoyancy truss 2 and the pile leg 4 working together, the overall stability of the independent lifting aquaculture cage during typhoons can be improved. Furthermore, since the aquaculture space enclosed by the netting is already at a certain depth below the water surface, this depth can provide a relatively calm aquaculture environment, enabling the independent lifting aquaculture cage to have better typhoon resistance.

[0070] Preferably, the multiple pile legs 4 are respectively arranged at the corners of the closed structure formed by the first buoyancy frame 21.

[0071] By placing the pile legs 4 at the corners of the closed structure formed by the first buoyancy frame 21, the pile legs 4 can provide strong support at the four corners of the buoyancy truss 2, thereby ensuring the stability of the support of the pile legs 4 for the overall structure.

[0072] Preferably, the buoyancy truss 2 further includes a plurality of fixed pile seats 24. The fixed pile seats 24 are provided at the corners of the closed structure formed by the first buoyancy frame body 21. The fixed pile seats 24 are provided with through holes in the vertical direction. The pile legs 4 pass through the through holes and are slidably connected to the fixed pile seats 24.

[0073] By setting the fixed pile base 24, a more stable limiting effect can be provided for the pile leg 4 located at the corner, avoiding the pile leg 4 from swinging left and right, and further improving the support stability of the pile leg 4 for the overall structure.

[0074] To further clarify, the buoyancy body is a foam block or an air bladder.

[0075] The buoyancy body can be a foam block or an air bladder to provide the aquaculture cage module with buoyancy greater than its own, so that the independent lifting aquaculture cage can float on the sea surface when towing, making it convenient for towing.

[0076] A method for using a towable, independently adjustable aquaculture cage, comprising at least one of the following steps:

[0077] The independent lifting aquaculture cages are towed to the designated location: such as... Figure 2 As shown, in the initial state, the horizontal plane where the lower end face of the pile leg 4 is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss 2 is located, and the horizontal plane where the lower end face of the net cage frame 3 is located is higher than or equal to the horizontal plane where the lower end face of the buoyancy truss 2 is located, so that the buoyancy truss 2 is located at the bottom of the independent lifting aquaculture net cage, and the independent lifting aquaculture net cage is towed to the designated position;

[0078] Installation of the independent lifting aquaculture cage at the designated location: After towing the independent lifting aquaculture cage to the designated location, as follows... Figure 1 As shown, the pile leg 4 is lowered and fixed (specifically, the pile leg 4 is lowered and inserted into the mud on the seabed), the net is installed on the net cage frame 3, and the net cage frame 3 is lowered so that part of the net cage frame 3 is below the horizontal plane;

[0079] The independent lifting of the cage frame 3 in the independently lifting aquaculture cage: as follows Figure 3 As shown, the cage frame 3 is raised above the horizontal plane, and each cage frame 3 is subjected to independent operation and maintenance operations. The operation operations can be catching fish, collecting fish, separating fish, and changing fish. The maintenance operations can be maintaining the netting or maintaining the cage frame 3.

[0080] The method of using the independently lifting aquaculture cage that is easy to tow is convenient to operate, can realize the individual lifting and lowering operation of the aquaculture cage, and is easy to maintain.

[0081] To further explain, the method of using the aforementioned easy-to-tow independent lifting aquaculture cage also includes the following steps:

[0082] like Figure 8 As shown, the second support rod 32 is lowered below the horizontal plane, and the buoyancy truss 2 is raised relative to the pile leg 4 so that the entire buoyancy truss 2 is completely above the horizontal plane;

[0083] Alternatively, the buoyancy body can be removed, and both the buoyancy truss 2 and the cage frame 3 can be lowered relative to the pile leg 4, so that the entire buoyancy truss 2 and the cage frame 3 are completely below the horizontal plane.

[0084] When a typhoon occurs, the buoyancy truss will be subjected to a large impact, and the water surface may submerge the upper surface of the aquaculture space enclosed by the netting. At this time, the second support rod can be lowered below the water level, and the buoyancy truss can be raised relative to the pile legs so that the entire buoyancy truss is completely above the water level. With the weight of the buoyancy truss and the pile legs working together, the overall stability of the independent lifting aquaculture cage can be improved during typhoons. Furthermore, since the aquaculture space enclosed by the netting is already at a certain depth below the water surface, this depth can provide a relatively calm aquaculture environment, enabling the independent lifting aquaculture cage to have good typhoon resistance.

[0085] Alternatively, the buoyancy body can be removed, for example, by deflating the airbag, and then lowering both the buoyancy truss and the net cage frame relative to the pile legs, so that the entire buoyancy truss and the net cage frame are completely below the horizontal plane (for example, 8 meters below the water surface). In this case, the buoyancy body will not affect the stability of the buoyancy truss below the horizontal plane, and since the aquaculture space enclosed by the net and the buoyancy truss are already at a certain depth below the water surface, this depth can provide a relatively calm aquaculture environment, enabling the independent lifting aquaculture net cage to have good typhoon resistance.

[0086] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.

The cage frame can be independently raised and lowered within the cage installation space, and the cage frame and the cage installation space are arranged in a one-to-one correspondence. The pile legs are vertically and vertically mounted on the first buoyancy frame. The first buoyancy frame and the second buoyancy frame are each provided with a receiving cavity for placing the buoyancy body; the aquaculture cage module also includes a first lifting drive mechanism and a second lifting drive mechanism, which are respectively disposed in the first buoyancy frame; the drive end of the first lifting drive mechanism is connected to the pile leg, and the first lifting drive mechanism drives the pile leg to move up and down relative to the buoyancy truss; the drive end of the second lifting drive mechanism is connected to the cage frame, and the second lifting drive mechanism drives the cage frame to move up and down relative to the buoyancy truss. The cage frame includes multiple lifting rods, multiple second support rods, and multiple second connecting rods. The lifting rods are arranged parallel to each other in the vertical direction, and the second support rods are arranged parallel to each other in the horizontal direction. The second support rods are connected between two adjacent lifting rods, and the second connecting rods are connected between two oppositely arranged second support rods. The second connecting rods are arranged in pairs to form a mesh frame structure. The driving end of the second lifting drive mechanism is connected to the lifting rods. The usage method includes the following steps: In the initial state, the horizontal plane at which the lower end face of the pile leg is located is higher than or equal to the horizontal plane at which the lower end face of the buoyancy truss is located, and the horizontal plane at which the lower end face of the net cage frame is located is higher than or equal to the horizontal plane at which the lower end face of the buoyancy truss is located, so that the buoyancy truss is located at the bottom of the independent lifting aquaculture net cage, thereby facilitating towing. After the independent lifting aquaculture cage is towed to the designated location, the legs are lowered and inserted into the mud on the seabed. Under the self-weight of the buoyancy truss and the cage frame, the legs are provided with a certain support force after being inserted into the mud, making the independent lifting aquaculture cage more stable at sea. Then, netting is installed on the cage frame to form an aquaculture space. Next, the cage frame is lowered so that it is below the horizontal plane. The upper end of the lifting rod is at a higher horizontal level than the upper end of the second support rod, causing the length of the lifting rod to protrude beyond the upper end of the second support rod. This allows the lifting rod to provide a greater descent distance, enabling the second support rod to descend to a certain depth below the water surface. When a typhoon arrives, the second support rod is lowered to a certain depth below the water surface, completely lowering the aquaculture space below the water surface. Simultaneously, the buoyancy truss is raised a certain distance relative to the pile legs. Since the pile legs are already inserted into the mud, their height remains unchanged; instead, the position of the buoyancy truss relative to the pile legs changes. This ensures that the entire buoyancy truss is completely above the water surface. The weight of the buoyancy truss, combined with the pile legs, improves the overall stability of the independent lifting aquaculture cage during typhoons. Furthermore, since the aquaculture space is already at a certain depth below the water surface, this depth provides a relatively calm aquaculture environment.
