[0029] In one embodiment, through the connection and assembly of the bottom base 10, the top connecting assembly 20 and the vertical support assembly 30, the net cage frame as a whole forms a three-dimensional stable "day" shaped seat bottom type truss structure, which can provide strong support for the net cage.

The placement position of the net cage can be adjusted under different weather and environmental conditions, so as to effectively avoid the influence of natural disasters on the net cage equipment and the breeding work.

[0038] As shown in Figures 4-5As shown, the two opposite circumferential surfaces of the cylinder of the base cross beam 111, the base diagonal brace 13, the top cross beam 211, the top diagonal brace 213 and the frame diagonal brace 32 are each provided with a row of fixing rings 321, the fixing ring 321 is semi-elliptical, the multiple fixing rings 321 of each row are arranged in parallel and a space is formed between each two fixing rings 321, and the outermost end of each fixing ring 321 is welded with a fixing rod 322, the fixing rod 322 is a long cylindrical body.

[0040] The top cross beam 211 and the base cross beam 111 are cylindrical bodies with equal size and length, the multiple base diagonal braces 13, the multiple top diagonal braces 213 and the multiple frame diagonal braces 32 are cylindrical bodies with equal cross-sectional size, the length of the short diagonal brace 131 is less than the length of the long diagonal brace 132, the length of the short diagonal brace 131 is equal to the length of the top diagonal brace 213, the cross-sectional size of the frame diagonal brace 32 is less than the cross-sectional size of the top cross beam 211 and the base cross beam 111, the cross-sectional size of the lifting support column 31 is greater than the cross-sectional size of the top cross beam 211 and the base cross beam 111, the length of the lifting support column 31 is greater than the length of the top cross beam 211 and the base cross beam 111, and the length and cross-sectional size of the support rod 33 are less than the length and cross-sectional size of the frame diagonal brace 32.

[0041] In one embodiment, the lifting support column 31 undertakes the main support task of the overall movement and lifting of the net cage, and a high-strength and more robust steel pipe is selected, and the length of the lifting support column 31 can be adjusted and installed as needed, such as extending the length of the lifting support column 31 below the bottom base 10 to serve as a net cage leg to penetrate into the seabed, and extending the length of the lifting support column 31 above the top connecting assembly 20 to reserve space for adjusting the lifting of the net cage and improve the stability and support strength above the net cage.

[0050] The modular floating net cage frame and net cage can achieve:

[0051] (1) Through the connection and assembly of the bottom base 10, the top connecting assembly 20 and the vertical support assembly 30, the net cage frame as a whole forms a three-dimensional stable "day" shaped seat bottom type truss structure, which can provide strong support for the net cage. In severe sea conditions, the bottom base 10 can adjust the position of the lifting support column 31 to extend the net cage leg into the seabed or fix it on the seabed rock, so that the whole net cage sinks into the seabed, ensuring the stability of the platform, thereby effectively avoiding the influence of natural disasters on the breeding equipment.

[0052] (2) The multiple triangular structures in the net cage frame formed by the intersection of the frame diagonal braces 32 of the multiple first trusses 11, second trusses 21 and third trusses 34 can disperse the load received by the net cage to multiple support points, reduce the stress intensity of a single support point, and improve the structural strength of the entire net cage. The net cage can better withstand various external forces and environmental factors during long-term use, is more wind and wave resistant, and has a longer service life.

[0053] (3) By setting the lifting clamping strip 311 on the lifting support column 31 and the lifting motor 312 on the base connecting piece 112 and the top connecting piece 212, which cooperates with the lifting clamping strip 311, the position adjustment of the lifting support column 31 can be controlled by the lifting adjustment of the lifting motor 312 on the lifting support column 31 to realize the lifting of the net cage, which is convenient for adjusting the placement position of the net cage under different weather and environmental conditions, thereby effectively avoiding the influence of natural disasters on the net cage equipment and breeding work. The length of the lifting support column 31 can be adjusted and installed as needed, such as extending the length of the lifting support column 31 below the bottom base 10 to serve as the net cage leg to penetrate into the seabed, and extending the length of the lifting support column 31 above the top connecting assembly 20 to reserve space for adjusting the lifting of the net cage and improve the stability and support strength above the net cage.

[0054] (4) By setting the fixed rod 322 and the plurality of fixed rings 321 on the plurality of cylinders constituting the net cage frame, the fixed rod 322 and the fixed ring 321 can enhance the stability and rigidity of the truss cylinder and the entire net cage structure, help resist external loads, reduce the risk of deformation and damage, and also facilitate the laying of netting and ropes and other components on the net cage, so that the components can work stably at the predetermined position and prevent displacement or falling under the action of external forces such as wind and waves.

[0055] (5) The setting of the two rows of fixed rings 321 facilitates the setting of double-layer netting on the frame, which is conducive to smoother water exchange, provides sufficient oxygen and a suitable living environment for farmed fish, and also increases the physical barrier of the net cage, reducing the risk of net breaking and fish escaping. At the same time, the double-layer netting improves the overall wind and wave resistance of the net cage, better protecting farmed fish from damage. The setting of multiple fixed rings 321 also facilitates adjusting the arrangement height of the netting as needed, and also facilitates replacing or repairing the netting when necessary. After the netting is set, the interior of the net cage can be divided into two breeding modules, enabling zoned breeding, and each zone can breed different fish to meet the growth needs of different fish. This can meet the production requirements of multiple varieties and batches, greatly improving the efficiency of net cage breeding.
