The present invention may further comprise:

1. the fixed pipe support include the hexagon frame that constitutes by six frame pipe connections, each summit department of hexagon frame connects a reinforcement pipe fitting, six reinforcement pipe fittings assemble in the center of hexagon frame with ballast water pump link to each other, six reinforcement pipe fittings cut apart six triangle-shaped units with the hexagon frame, the box with a net passes through fixed pipe fitting and installs at every triangle-shaped unit center.

2. The net cage is a spherical net cage, the outside of the spherical net cage is provided with annular fixed pipe fittings, and the annular fixed pipe fittings are connected with three vertexes of the triangular unit through three fixed pipe fittings and are communicated with the inner cavity.

3. The fixed pipe frame is provided with a hook.

4. And a cable is linked to each of six vertexes of the hexagonal frame.

5. The ocean platform is a semi-submersible type ocean platform.

Aiming at the defects of the traditional cage culture equipment, the culture equipment comprises a semi-submersible type ocean platform and a plurality of arrayed cages consisting of cage units, each group of cage arrays comprises a plurality of cages and a fixed pipe frame structure, and each group of cage units is connected with a plurality of anchor chain devices and is used for fixing the cages after reaching the operation depth. The fixed pipe frame structure contains ballast water, and the water quantity is adjusted through a central ballast water pump so as to adjust the sinking depth. Each net cage is internally provided with a bait feeding device which is connected with a bait bin pipeline of the semi-submersible platform through a feeding pipeline and used for feeding and breeding fish schools. When seasons change or the operation area needs to be adjusted, the cable of the towing ship is used for being connected with the hook of the spherical steel frame structure, the net cage is dragged to move, and the operation area is adjusted.

The invention also improves the square and cylindrical net cage structure into a spherical net cage, and utilizes a steel frame structure to carry out fixed marshalling, thereby greatly improving the breeding efficiency. Meanwhile, when seasons change, the towing ship can be used for moving on the sea, and long-time operation can be carried out in a region with proper water temperature. The net cage is a fully submerged net cage, and can effectively reduce the influence of sea stormy waves, marine organism attachments and the like.

Detailed Description

The invention is described in more detail below by way of example.

Referring to fig. 1, the first embodiment of the fully submerged array type aquaculture apparatus of the present invention comprises an ocean platform and a net cage array formed by arranging a plurality of net cage units. With reference to fig. 3 and 4, each net cage unit includes a fixed pipe frame 5, a net cage 6 fixed on the fixed pipe frame, a cable 8 connected to the fixed pipe frame, and an anchor 7 at the lower part of the cable, the fixed pipe frame is formed by connecting pipe fittings, and a ballast water pump 10 communicated with the pipe fittings is arranged at the central position of the fixed pipe frame. Referring also to fig. 2, the ocean platform includes a platform body 1 and a bait bin 2 disposed on the platform body. The bait bin is connected with the feeding pipelines 4 of the net box units through bait bin pipelines 3.

The second embodiment of the present invention is the first embodiment: the fixed pipe support includes the hexagon frame that constitutes by six frame pipe connections, and each summit department of hexagon frame connects a reinforcement pipe fitting, six reinforcement pipe fittings collect in the center of hexagon frame with ballast water pump link to each other, six reinforcement pipe fittings cut apart six triangle-shaped units with the hexagon frame, the box with a net passes through fixed pipe fitting and installs at every triangle-shaped unit center. And a cable is linked to each of six vertexes of the hexagonal frame.

The third embodiment of the present invention is the first or second embodiment: the net cage is a spherical net cage, the outside of the spherical net cage is provided with annular fixed pipe fittings, and the annular fixed pipe fittings are connected with three vertexes of the triangular unit through three fixed pipe fittings and are communicated with the inner cavity.
