[0025] At present, most of the marine fish farming cages adopt traditional configurations, which have obvious deficiencies in terms of steel usage, wind and wave resistance, personnel safety and farming efficiency. Specifically, traditional cage designs often have high freeboards, which leads to increased steel usage and higher costs; at the same time, the phenomenon of rising waves is serious, threatening personnel safety.

[0026] Therefore, a new type of aquaculture cage is urgently needed to solve the safety problems caused by the high freeboard design and waves of the existing aquaculture cages.

[0027] In order to solve the above problems, the present invention proposes a rectangular aquaculture cage with low freeboard.

[0028] See also Figure 1 In one embodiment of the present invention, the low freeboard rectangular aquaculture cage includes a base 1, a frame structure 2, a superstructure structure 3 and a plurality of second support columns 4, the middle part of the base 1 is hollowed out and provided with a first net; the frame structure 2 includes a plurality of first support columns 21 and a plurality of connecting components 22, the plurality of first support columns 21 are arranged on the base 1, and the plurality of connecting components 22 are arranged between two adjacent first support columns 21; a second net is arranged on the outer side of the frame structure 2; the second support columns 4 are arranged on the base 1, and the height of the second support columns 4 is greater than the height of the first support columns 21; the superstructure structure 3 is arranged on the top of the second support columns 4; a walkway and an operation room are arranged inside the superstructure structure 3, and aquaculture equipment is arranged inside the operation room.

[0029] It should be noted that freeboard refers to the vertical distance from the full load waterline to the upper edge of the structure, that is, when a structure floats on the water, the distance between its upper structure and the water surface. In the present invention, when a rectangular aquaculture cage with low freeboard floats on the water, the portion of the top of the first support column 21 protruding above the water surface is the freeboard. Since the base 1 is provided with a first net, the outside of the frame structure 2 formed by the first support column 21 and the connecting assembly 22 is provided with a second net, so the area enclosed by the first net and the second net is the breeding area of ​​the rectangular aquaculture cage. The height of the freeboard reflects the height of the first support column 21 protruding above the water surface. In order to prevent the farmed fish from jumping out of the water and out of the second net, the freeboard needs to be set to a suitable height to prevent the farmed fish from escaping; but the height of the freeboard does not need to be too high, otherwise it will greatly increase material consumption and costs.

[0030] The technical solution of the present invention adopts a design of low freeboard and high superstructure, that is, by separately setting the first support column 21 and the second support column 4, and making the height of the second support column 4 higher than the height of the first support column 21, the superstructure structure 3 supported by the second support column 4 is located at a higher position, avoiding the impact of waves and waves on the superstructure structure 3; at the same time, the design height of the first support column 21 as the freeboard can be reduced to a necessary limit, which can not only avoid the escape of farmed fish due to the low height of the second net, but also save steel as much as possible and reduce the manufacturing cost of the cage. In addition, since the superstructure is set on the top of the second support column 4, the staff does not need to operate the equipment through the aisle at the bottom of the cage in severe sea conditions, but only needs to go through the aisle in the superstructure to go to the operation room to operate the aquaculture equipment, thereby ensuring the safety of personnel and equipment.

[0031] In addition, in order to solve the bearing problem of the superstructure, in the embodiment of the present invention, please refer to Figure 1 The superstructure structure 3 is set as a box beam, the outside of the box beam is a closed structure, the inside of the box beam is a hollow structure, and the inside of the box beam is provided with a walkway and an operating room. In this way, by setting the superstructure as a box beam, the box beam as the main load-bearing structure is combined with the superstructure function, and the box beam can provide extremely strong bending and torsional strength for the superstructure structure 3 located at a higher height, thereby ensuring the strength reliability of the superstructure. Compared with the superstructure of existing oil platforms, the superstructure of oil platforms has rich functions, large space requirements, and extremely heavy equipment. Even if it is designed as a box beam, it cannot meet the strength requirements; for the breeding platform, its demand for special breeding equipment and the number of operators is relatively small. The design of introducing a box beam is very consistent with the economic principle of the cage design. The design of combining the box beam with the superstructure function in the present invention not only provides the necessary load-bearing components, but also enriches the functionality of the superstructure and improves the utilization rate of the overall structure.

[0032] In order to solve the problem that it is inconvenient for the staff to travel between the superstructure structure 3 and the frame structure 2, in the embodiment of the present invention, the second support column 4 is provided with a staircase corridor, the top of which extends to the bottom of the box beam, and the bottom of which extends to the connection assembly 22. In this way, by providing the above-mentioned staircase corridor, the staff can conveniently travel between the box beam and the connection assembly 22 through the staircase corridor, and then go to each first support column 21 from the connection assembly 22, which provides convenience for the staff to inspect and maintain the frame structure 2.

[0033] In order to solve the problem of balancing the low freeboard rectangular aquaculture cage on the waves, in the embodiment of the present invention, refer to Figure 1 , multiple first support columns 21 are symmetrically arranged about the gravity vertical line of the base 1; the second support column 4 is arranged in the middle of the base 1, and the center of gravity of the superstructure structure 3 coincides with the gravity vertical line of the base 1.

[0034] In this embodiment, the first support column 21 is symmetrically arranged about the vertical line of gravity of the base 1 to avoid the influence of the arrangement of the first support column 21 on the center of the base 1, and the second support column 4 is arranged in the middle of the base 1, and the center of gravity of the superstructure structure 3 is made to coincide with the vertical line of gravity of the base 1, so that the second support column 4, superstructure and other components or building structures can have an influence on the center of the base 1 as much as possible, which helps the aquaculture platform to maintain the balance of the center of gravity, reduce the impact of wave impact and waves on the stability of the aquaculture platform, and improve the aquaculture platform's ability to resist wind and waves.

[0035] In order to solve the problem of insufficient strength of the frame structure 2, in the embodiment of the present invention, please refer to Figure 1 The base 1 includes two trusses 11 and a plurality of first connecting rods 12. The extension direction of the two trusses 11 is arranged along the first direction. A plurality of first connecting rods 12 are arranged between the two trusses 11. A first net is arranged in the area enclosed by the two trusses 11 and the plurality of first connecting rods 12. A plurality of first supporting columns 21 are arranged at intervals along the first direction on the two trusses 11. The connecting assembly 22 includes a transverse connecting rod 221 and a longitudinal connecting rod 222. A transverse connecting rod 221 is arranged between two adjacent first supporting columns 21 on the same truss 11, and a longitudinal connecting rod 222 is arranged between two adjacent first supporting columns 21 on different trusses 11. In this way, by arranging transverse supporting rods and longitudinal supporting rods between the first supporting columns 21, the transverse and longitudinal strength of the frame structure 2 is improved, thereby improving the wind and wave resistance of the frame structure 2.

[0036] In order to avoid excessive stress concentration at the connection between the transverse connecting rod 221, the longitudinal connecting rod 222 and the first support column 21, in the embodiment of the present invention, please refer to Figure 1, a triangular connecting plate 23 is provided between adjacent transverse connecting rods 221 and longitudinal connecting rods 222. In this way, by providing a triangular connecting plate 23 between adjacent transverse connecting rods 221 and longitudinal connecting rods 222, the local stiffness between the transverse connecting rods 221 and longitudinal connecting rods 222 is improved, the anti-deformation capacity of the local area is improved, and at the same time, excessive stress concentration is avoided to damage the structures of the transverse connecting rods 221, the first support column 21, and the longitudinal connecting rods 222, which helps to more evenly distribute the load to each component and ensure the safety of each component.

[0037] In order to solve the problem that the longitudinal section of the aquaculture platform is not strong enough and is easily damaged when the aquaculture platform is affected by severe sea conditions, in the embodiment of the present invention, please refer to Figure 1 The rectangular breeding cage also includes multiple second connecting rods 5; the first end of the second connecting rod 5 is connected to the first support column 21, the second end of the second connecting rod 5 is connected to the longitudinal connecting rod 222, and the second connecting rod 5, the longitudinal connecting rod 222 and the first support column 21 form a triangular support structure; or, the first end of the second connecting rod 5 is connected to the first support column 21, the second end of the second connecting rod 5 is connected to the first connecting rod 12, and the second connecting rod 5, the first connecting rod 12 and the first support column 21 form a triangular support structure.

[0038] In this embodiment, a second connecting rod 5 is provided, and the second connecting rod 5, the first support column 21, and the longitudinal connecting rod 222 form a triangular support structure, or the second connecting rod 5, the first support column 21, and the first connecting rod 12 form a triangular support structure, so that the stability of the triangular support structure is utilized to improve the longitudinal cross-sectional structural strength of the breeding platform, thereby greatly improving the overall strength and wind and wave resistance of the cage.

[0039] In order to solve the problem of unreasonable water separation in traditional cage aquaculture, and the need to improve aquaculture efficiency and safety, in an embodiment of the present invention, a third net is provided on the triangular support structure. In this way, by providing the third net on the triangular support structure, the water body originally enclosed by the first net and the second net in the low freeboard rectangular aquaculture cage is further divided into multiple areas, and different types of fish can be cultured in each area, thereby increasing the number of fish that can be cultured; in addition, important fish species can also be set in the area enclosed by the third net for culture, and even if the second net on both sides along the first direction and the opposite side of the first direction is broken, the important fish species in the area enclosed by the third net can be prevented from escaping, thereby improving the safety of aquaculture and avoiding huge economic losses caused by the damage of a single net.

[0040] Furthermore, as an optional embodiment, the mesh of the third net can be set to a triangle. Due to the stability of the triangle, even when the mesh of the net is subjected to external forces such as water flow, it is not easy to deform or twist, which helps to maintain the overall shape of the third net and ensure that it can still maintain good performance under harsh environmental conditions.

[0041] In order to solve the problem that the transverse section of the aquaculture platform is insufficient in structural strength and is easily damaged when the aquaculture platform is affected by severe sea conditions in the transverse direction, in an embodiment of the present invention, the low freeboard rectangular aquaculture cage also includes a plurality of third connecting rods; the first end of the third connecting rod is connected to the first support column 21, and the second end of the third connecting rod is connected to the transverse connecting rod 221, and the third connecting rod, the transverse connecting rod 221 and the first support column 21 form a triangular support structure.

[0042] In this embodiment, a third connecting rod is provided, and a triangular support structure is formed between the third connecting rod, the transverse connecting rod 221 and the first support column 21. The stability of the triangular support structure is utilized to improve the longitudinal cross-sectional structural strength of the breeding platform, thereby greatly improving the overall strength and wind and wave resistance of the cage.

[0043] Since the rectangular aquaculture cage will float under the action of ocean currents and waves when floating on the sea surface, if the rectangular aquaculture cage drifts away from the predetermined sea area, not only will it be difficult to locate the rectangular aquaculture cage for aquaculture and fish harvesting, but the sea conditions outside the predetermined sea area may not be suitable for the growth of fish species in the rectangular aquaculture cage. Therefore, it is necessary to prevent the rectangular aquaculture cage from drifting away from the predetermined sea area. In order to solve the problem of how to prevent the rectangular aquaculture cage from drifting away from the predetermined sea area, in an embodiment of the present invention, the rectangular aquaculture cage also includes a mooring component, the fixed end of the mooring component is arranged at the bottom of the base 1, and the movable end of the mooring component is used to connect with the seabed.

[0044] In this way, by providing a mooring component, when the rectangular aquaculture cage with low freeboard reaches the predetermined sea area, the rectangular aquaculture cage can be moored on the seabed by the mooring component, so that the rectangular aquaculture cage is only allowed to float in the predetermined sea area, and the rectangular aquaculture cage is prevented from drifting away from the predetermined sea area. Among them, the fixed end of the mooring component can be set as a tensioning mechanism, and the movable end of the mooring component can be set as an anchor cable. After the anchor cable is fixed to the seabed, the anchor cable is tensioned by the tensioning mechanism, so that the rectangular aquaculture cage with low freeboard is moored in the predetermined sea area, and the rectangular aquaculture cage is prevented from drifting out of the predetermined sea area.

[0045] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
