[0031] Gravity-type deep-water cages are low-cost and highly mature in technology. They will remain an important facility support for the development of deep-sea aquaculture in the future. However, as cage aquaculture expands to the open sea, large waves and rapids, especially extreme weather such as typhoons, will seriously affect the safety of the facilities. In related technologies, gravity-type deep-water cages cannot cope with large waves and rapids or extreme weather such as typhoons. To cope with extreme weather, one can only rely on "hard resistance", which threatens the safety of cage facilities. Even if the facilities are not damaged, there are still major hidden dangers to the survival of farmed organisms in extreme weather. This application provides a lifting aquaculture cage with a lifting function. Before the arrival of extreme sea conditions such as typhoons, the lifting control system can complete the overall diving of the cage body to achieve the purpose of resisting typhoons and avoiding risks.

[0032] In view of this, the lifting aquaculture cage provided in the embodiment of the present application includes a main truss system, a net system and a mooring system; the main truss system includes a truss and a pontoon, and the pontoon and the net system are both connected to the truss; one end of the mooring system is connected to the truss, and the other end is used to connect to an anchor on the seabed; the lifting aquaculture cage is made to dive by discharging the gas in the pontoon; and the lifting aquaculture cage is made to float by filling the pontoon. The lifting and lowering control of the lifting aquaculture cage provided in the embodiment of the present application is mainly achieved by inflating or exhausting the pontoon. Specifically, by discharging the gas in the pontoon, water flows into the pontoon, reducing the buoyancy of the pontoon, thereby achieving the purpose of diving the lifting aquaculture cage. By filling the pontoon with gas, water is discharged from the pontoon, increasing the buoyancy of the pontoon, thereby achieving the purpose of floating the lifting aquaculture cage. By utilizing the lifting function of the lifting aquaculture cage, before the arrival of extreme sea conditions such as typhoons, the lifting control system can complete the overall diving of the cage body to achieve the purpose of typhoon resistance and risk avoidance, thereby ensuring the safety of the lifting aquaculture cage.

[0033] Referring to Figures 1 to 5, the liftable aquaculture cage 10 provided in the embodiment of the present application includes a main truss system 111, a net system 12, and a mooring system 13. The main truss system 111 includes a truss 111 and a pontoon 112, both of which are connected to the truss 111. The mooring system 13 is connected to the truss 111 at one end and to an anchor on the seabed at the other end. The liftable aquaculture cage 10 is submerged by discharging gas from the pontoon 112, and is raised by filling the pontoon 112 with gas.

[0034] It should be noted that the lifting control of the liftable aquaculture cage 10 provided in the embodiment of the present application is mainly achieved by inflating or exhausting air into the buoyancy box 112. Specifically, by exhausting the gas in the buoyancy box 112, water flows into the buoyancy box 112, reducing the buoyancy of the buoyancy box 112, thereby achieving the purpose of diving the liftable aquaculture cage 10. By inflating gas into the buoyancy box 112, water is discharged from the buoyancy box 112, increasing the buoyancy of the buoyancy box 112, thereby achieving the purpose of floating the liftable aquaculture cage 10. Utilizing the lifting function of the liftable aquaculture cage 10, before the arrival of extreme sea conditions such as typhoons, the lifting control system can complete the overall diving of the cage body to achieve the purpose of typhoon resistance and risk avoidance, thereby ensuring the safety of the liftable aquaculture cage 10. Modes for Carrying Out the Invention

[0035] In an optional exemplary embodiment, the main truss 111 system includes a plurality of pontoons 112 ; the plurality of pontoons 112 are arranged around the truss 111 at equal intervals.

[0036] It should be noted that, specifically, in this embodiment, the main truss 111 system includes a plurality of pontoons 112, which are arranged at equal intervals around the truss 111. This arrangement of the pontoons 112 at equal intervals allows for evenly distributed buoyancy throughout the truss 111, effectively ensuring the stability of the entire truss 111.

[0037] In an optional exemplary embodiment, the liftable aquaculture cage 10 further includes an air filling and exhaust pipe 14 , which is connected to the buoyancy box 112 and is used to fill gas into the buoyancy box 112 to enable the liftable aquaculture cage 10 to float.

[0038] It should be noted that, specifically, in this embodiment, an inflation / exhaust pipe 14 is provided for filling the buoyancy box 112 with gas, and the inflation / exhaust pipe 14 is connected to the buoyancy box 112 to enable the lifting aquaculture cage 10 to float upward. During use, the inflation / exhaust pipe 14 can fill the buoyancy box 112 with gas, thereby enabling the lifting aquaculture cage 10 to float upward. When the lifting aquaculture cage 10 needs to dive, water is allowed to flow in, which will discharge the gas in the buoyancy box 112, reduce the buoyancy of the buoyancy box 112, and thereby enable the entire lifting aquaculture cage 10 to dive downward, thereby achieving the purpose of avoiding danger.

[0039] It is understandable that the inflation and exhaust pipe 14 is detachably connected to the float box 112 , and when inflation is required, it can be connected to the float box 112 .

[0040] In an optional exemplary embodiment, the truss 111 includes four frame frames 1111 connected end to end in sequence, and the four frame frames 1111 form a closed shape; two buoyancy tanks 112 are arranged at intervals on each frame frame 1111; the number of the inflation and exhaust pipes 14 is two, and each inflation and exhaust pipe 14 is connected to four buoyancy tanks 112 through a ventilation pipe.

[0041] It should be noted that, specifically, in this embodiment, the truss 111 includes four frame frames 1111 connected end-to-end, forming a closed shape. Two pontoons 112 are spaced apart on each frame 1111. There are two inflation and exhaust pipes 14, each connected to four pontoons 112 via a vent pipe. This arrangement ensures that the number of pontoons 112 on each frame 1111 of the truss 111 is the same, resulting in a uniform buoyancy force on each frame 1111, thereby ensuring smooth ascent or descent of the truss 111 as a whole and ensuring the stability of the truss 111.

[0042] Specifically, in this embodiment, the closed shape formed by the four frames 1111 may be a rectangle or a square.

[0043] It is understandable that the number of frames 1111 constituting the truss 111 is not limited here. In other specific embodiments, the number of frames 1111 can be set to one, two, three, five, or more according to the needs of the user. When there is one frame 1111, the frame 1111 can be enclosed into a circular structure; when there are two frames 1111, the frame 1111 can be enclosed into an ellipse; when there are three frames 1111, the three frames 1111 can be enclosed into a triangle; when there are five frames 1111, the five frames 1111 can be enclosed into a pentagon. When there are more frames 1111, the multiple frames 1111 can be enclosed into a polygon according to the needs of the user.

[0044] It should also be noted that there are two inflation and exhaust pipes 14, each connected to four buoyancy boxes 112 via a vent pipe. This arrangement allows four buoyancy boxes 112 to be filled simultaneously through a single inflation and exhaust pipe 14, effectively improving inflation efficiency. Furthermore, the two inflation and exhaust pipes 14 are connected through a branch connection, each controlling half of the buoyancy boxes 112. During deflation, the net cages dive, while during inflation, they rise.

[0045] It is understandable that the specific number of inflation and exhaust pipes 14 and float boxes 112 is not limited here. In other specific embodiments, the number of inflation and exhaust pipes 14 can be set to one or four, and the number of float boxes 112 on each frame 1111 can be set to one or three, etc. according to the specific needs of the user.

[0046] In an optional exemplary embodiment, the pontoon 112 is a steel pontoon 112 , the truss 111 is a steel truss 111 , and the pontoon 112 is welded to the truss 111 .

[0047] It should be noted that, specifically, in this embodiment, the pontoon 112 is made of steel, and the trusses 111 are made of steel. This arrangement effectively ensures the structural stability of the pontoon 112 and the trusses 111, thereby ensuring the service life of the liftable aquaculture cage 10. Furthermore, the pontoon 112 is welded to the trusses 111, ensuring the stability of the connection between the pontoon 112 and the trusses 111, making the connection between the two more secure.

[0048] In an optional exemplary embodiment, the net system 12 includes a net 121 and sinkers 122, the net 121 includes side nets 1211 and a bottom net 1212, the side nets 1211 are arranged around the edge of the bottom net 1212, so that the side nets 1211 and the bottom net 1212 constitute a breeding space; the sinkers 122 are arranged at equal intervals on the edge of the bottom net 1212.

[0049] It should be noted that, specifically, in this embodiment, the net system 12 includes a net 121 and sinkers 122. The net 121 includes side nets 1211 and a bottom net 1212. The side nets 1211 are arranged around the edges of the bottom net 1212 so that the side nets 1211 and the bottom net 1212 form a breeding space; the sinkers 122 are arranged at equal intervals on the edges of the bottom net 1212. The sinkers 122 are arranged at equal intervals on the edges of the bottom net 1212 to effectively tension the net 121, ensuring that the net 121 does not deform significantly in high sea conditions.

[0050] In an optional exemplary embodiment, the side net 1211 is connected to the bottom net 1212 at an angle, so that the cross-sectional area of ​​the open end of the breeding space is larger than the area of ​​the bottom net 1212 .

[0051] It should be noted that, specifically, in this embodiment, the side nets 1211 are connected to the bottom net 1212 at an angle so that the cross-sectional area of ​​the opening end of the breeding space is larger than the area of ​​the bottom net 1212. This arrangement makes the longitudinal cross-section of the net 121 have a trapezoidal structure, that is, the opening is larger.

[0052] It should also be noted that the side nets 1211 are obliquely connected to the bottom net 1212, which can effectively reduce the impact of water flow on the side nets 1211, thereby preventing the side nets 1211 from being deformed due to the impact of water flow.

[0053] Furthermore, the side nets 1211 are connected to the bottom net 1212 at an angle, and the cross-sectional area of ​​the open end of the breeding space is larger than the area of ​​the bottom net 1212. In other words, the side nets 1211 are tilted toward the center of the net 121, with their tops away from the main truss system 111, thereby preventing friction between the main truss system 111 and the net 121, which could damage the net 121.

[0054] In an optional exemplary embodiment, the angle between the side net 1211 and the vertical downward direction is 10° to 20°.

[0055] Exemplarily, the angle between the side net 1211 and the vertical downward direction is 15°.

[0056] It is understandable that the angle between the side net 1211 and the vertical downward direction is not limited here. In other specific embodiments, the angle between the side net 1211 and the vertical downward direction can be selected according to the environmental conditions of the operating sea area.

[0057] In an optional exemplary embodiment, the mooring system 13 includes a cage connecting rope 131, a grid rope 132, a mooring rope 133 and a buoy 134; one end of the cage connecting rope 131 is connected to the truss 111, and the other end is connected to the grid rope 132 at equal intervals; one end of the mooring rope 133 is connected to the grid rope 132 and to the connection between the cage connecting rope 131 and the grid rope 132, and the other end of the mooring rope 133 is used to connect to an anchor on the seabed; the buoy 134 is provided on the side of the mooring rope 133 close to the grid rope 132 and at the connection between the mooring rope 133 and the grid rope 132.

[0058] It should be noted that, specifically, in this embodiment, one end of the cage connecting rope 131 is connected to the truss 111, and the other end is connected to the mesh rope 132 at equal intervals. One end of the mooring rope 133 is connected to the mesh rope 132 and to the junction of the cage connecting rope 131 and the mesh rope 132. The other end of the mooring rope 133 is used to connect to an anchor on the seabed. This ensures the stable operation of the cage body under environmental loads such as wind, waves and currents, and provides anchoring.

[0059] It should be noted that the buoy 134 can be used to ensure that buoyancy is provided for the cage system when the cage is submerged.

[0060] Exemplarily, the grid rope 132 has four side ropes 135, and the four side ropes 135 are connected end to end in sequence to form the grid rope 132. The connection between two adjacent side ropes 135 is a connection node 136. The grid rope 132 has four connection nodes 136; each connection node 136 is connected to two cage connection ropes 131; each connection node 136 is also connected to two mooring ropes 133, and each mooring rope 133 is provided with a buoy 134 near the connection node 136; each connection node 136 is connected to a buoy 134, and forms three vertices of a triangle with the two buoys 134 near each connection node 136.

[0061] It is understood that the mesh ropes 132 have four side ropes 135 to form a rectangle. The mesh ropes 132 can also be formed with other suitable numbers of side ropes 135 according to user needs to form other suitable shapes, and can also be adaptively adjusted according to the shape of the truss 111.

[0062] At the same time, the number of the buoys 134 can also be adaptively adjusted according to the needs of the user. The shape of the arrangement of the buoys 134 is not limited to a triangle, and can also be set to other suitable shapes according to specific circumstances.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

[0064] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.
