[0002] At present, my country's marine aquaculture is mainly concentrated in shallow offshore waters. The aquaculture method is extensive, the aquaculture layout is unreasonable, the aquaculture density is too high, and the aquaculture quality is not high. The limited coastal marine resources can no longer bear the pressure of the continuous growth of the total amount of aquatic products. my country has vast deep-sea aquaculture sea resources. The state encourages the development of deep-sea aquaculture and the establishment of marine granaries. Deep-sea aquaculture cages are located in deeper waters with open waters and smooth water flow. They can reduce the problems of slow fish growth and high disease incidence caused by poor water exchange and unstable water quality in ordinary cage aquaculture.

[0003] At present, the circumference of the cages used for deep-sea aquaculture in China is mostly between 60m and 120m. In very few projects, the circumference of the cages can reach more than 160m. The cages are mainly single-port dispersed anchoring, and a few cages are anchored in groups. The single-port fixed cages are arranged more dispersedly, and the water exchange of the cages is more unobstructed, but there are also problems such as the distribution of cage anchor cables, large occupation of water area, inconvenience in daily aquaculture operations and low efficiency of aquaculture operations. Foreign cage aquaculture technology appeared earlier and has become more mature. Most small cages are grouped with frame anchoring, which has improved the aquaculture efficiency to a certain extent. However, the anchoring of cages in groups still has a series of problems such as the large occupation of water area by the anchor system, affecting the navigation of aquaculture supporting ships, and difficulty in dredging the seabed. Therefore, how to simplify the anchoring method of the cages and reduce the occupation of water areas is an urgent problem to be solved. Utility Model Content

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0042] See also Figures 1 to 6The utility model provides a marine ranch cage group device based on pile foundations and pontoon fixation, including multiple cages 1 and an anchoring system, and also including a combined floating body mechanism 2 and a mooring cable 3. The combined floating body mechanism 2 floats on the sea surface. The combined floating body mechanism 2 includes two components, namely a floating body unit 22 and a pontoon unit 21, and the components are flexibly connected so that the components can move relative to each other. The combined floating body mechanism 2 is a grid structure, in which a grid space 23 for arranging the cages 1 is formed; the cages 1 are arranged in the grid space 23; a mooring cable 3 is arranged between the cages 1 and the combined floating body mechanism 2 for connection; the anchoring system includes a plurality of pile foundations 4, which are inserted into the seabed soil, and a clamp 211 structure is provided on the pontoon unit 21, and the clamp 211 is sleeved on the pile foundation 4 through a clamp through hole opened thereon, and can move up and down along the pile foundation 4.

[0043] The marine ranch cage group device of the utility model is connected with each cage 1 through a combined floating body mechanism 2 and a mooring cable 3. The combined floating body mechanism 2 provides buoyancy through a floating body unit 22 and a pontoon unit 21. The combined floating body mechanism 2 is used to provide multiple anchoring points for the cage 1, and the position of the cage 1 is stabilized through the mooring cable 3. The anchoring system adopts a pile foundation 4. Through the anchoring effect of the pontoon unit 21 in the combined floating body mechanism 2, the position of the combined floating body mechanism 2 is stabilized. On the one hand, the pile foundation 4 itself occupies little space in the water area. On the other hand, since it is no longer necessary to set up an anchoring system to anchor each cage 1 individually, the anchoring system can be significantly simplified. Therefore, the marine ranch cage group device as a whole occupies little space in the water area and does not affect the navigation of the breeding ship in the ranch. When multiple cages 1 are arranged in combination, it is convenient to set a suitable spacing. In addition to anchoring the cages 1, the combined floating structure 2 also has the pontoon unit 21 as the main equipment installation platform and offshore operation platform, which facilitates the arrangement of various aquaculture equipment and the aquaculture operations of the staff, thereby improving the efficiency of the aquaculture operations. In addition, since the combined floating structure 2 is relatively large in size, the combined floating structure 2 can select suitable floating units 22 and pontoon units 21 for combination according to actual needs, which is flexible and convenient to use. The entire combined floating structure 2 has a certain degree of flexibility, can float better on the sea surface, is less affected by wind and waves, and can ensure the anchoring effect of multiple cages 1.

The transverse partition 202 is composed of a plurality of floating units 22 and a plurality of pontoon units 21 connected in series, and can also be composed of a floating unit 22 or a pontoon unit 21. The longitudinal partition 203 is composed of a plurality of floating units 22, and can also be composed of a floating unit 22 and a pontoon unit 21. The transverse partition 202 and the longitudinal partition 203 are both arranged in the outer frame portion 201, and the two are arranged vertically to divide the space in the outer frame portion 201 into a plurality of grid spaces 23. The number of the transverse partitions 202 and the longitudinal partitions 203 can be set according to actual needs. When there are multiple longitudinal partitions 203, they are preferably arranged at equal intervals. When there are multiple transverse partitions 202, they are also arranged at equal intervals.

The mooring cable 3 is mainly connected between the pontoon unit 21 of the combined floating structure 2 and the net cage 1, which is convenient for assembly operation on the pontoon unit 21. The mooring cable 3 can also be set between the floating unit 22 and the net cage 1 for connection. In addition, the floating unit 22 can also be connected to the pile foundation 4 through a clamp or other structure.
