[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-Figure 5 The present invention provides a deep-sea full-stage sea urchin culture cage, comprising:

[0032] A growing box 3, a medium-sized growing box 2 is arranged in the growing box 3, a seedling raising box 1 is arranged in the medium-sized growing box 2, and floating components for making the growing box 3, the medium-sized growing box 2 and the seedling raising box 1 float on the sea surface are respectively arranged on the top of the growing box 3, the medium-sized growing box 2 and the seedling raising box 1;

[0033] A plurality of connection components are respectively fixedly connected between the top of the growing box 3 and the top of the medium culture box 2 and between the top of the medium culture box 2 and the top of the seedling box 1.

[0034] The nursery box 1 is located at the innermost part of the sea urchin farming net cage of the present invention, the growing box 3 is located at the outer layer of the sea urchin farming net cage of the present invention, the intermediate culture box 2 is located between the nursery box 1 and the growing box 3, and the adjacent boxes are fixedly connected and interconnected with each other at the upper part of the sea urchin farming net cage to form a multi-layer nested structure. On the whole, the sea urchin farming net cage of the present invention adopts a multi-layer nested structure, which can effectively reduce the impact of the ocean current environment on the net cage nursery box and provide a suitable habitat for the seedlings; the outer large mesh growing box is conducive to the diffusion of aquaculture waste and ensures the quality of the aquaculture environment; the nested structure of the nursery box, the intermediate culture box and the growing box meets the environmental requirements of sea urchins at different growth stages and realizes full-stage deep-sea aquaculture.

[0035] According to a further optimized solution, the floating assembly includes a float 11, which is fixedly connected to the top of the growing box 3, the medium culture box 2 and the seedling box 1.

[0036] In this embodiment, the floating body 11 is selected to be an annular barrel structure.

[0037] like Figure 1 As shown, the floating body 11 can provide buoyancy for the nursery box 1, the medium culture box 2 or the growing box 3 by using its barrel-shaped structure, so that it can float in the deep sea environment. At the same time, the floating body 11 is annular, which can assist in opening the nursery box 1, the medium culture box 2 or the growing box 3 to form a breeding space inside.

[0038] According to a further optimization scheme, the growing box 3 includes an outer side net 10, which is in an annular structure. The float 11 on the top of the growing box 3 is fixedly connected to the top of the outer side net 10, and the bottom of the outer side net 10 is fixedly connected to the outer bottom net 9.

[0039] According to a further optimization scheme, the middle training box 2 includes a middle layer side net 14, which is in an annular structure. The float 11 on the top of the middle training box 2 is fixedly connected to the top of the middle layer side net 14, and the bottom of the middle layer side net 14 is fixedly connected to the middle layer bottom net 13.

[0040] According to a further optimization scheme, the nursery box 1 comprises an inner side net 16 which is an annular structure, and the float 11 at the top of the nursery box 1 is fixedly connected to the top of the inner side net 16 , and the bottom of the inner side net 16 is fixedly connected to the inner bottom net 15 .

[0041] According to a further optimization scheme, the medium culture box 2 can be used as the growing box 3, but the growing box 3 cannot be used as the seedling box 1 and the medium culture box 2.

[0042] Further optimization scheme, such as Figure 4 As shown, the tops of the nursery box 1, the medium culture box 2 and the growing box 3 are all provided with mesh covers 12, and the main function of the mesh covers 12 is to prevent the sea urchins from escaping.

[0043] According to a further optimization scheme, the vertical distance between the inner bottom net 15 and the middle bottom net 13, and between the middle bottom net 13 and the outer bottom net 9 is not less than 0.5 m.

[0044] According to a further optimization scheme, the horizontal distance between the inner side net 16 and the middle side net 14, and between the middle side net 14 and the outer side net 10 is not less than 1.5 m.

[0045] By maintaining the necessary distance between the bottom nets and the side nets, it can be ensured that there is no friction or collision between the nets and the discharge of aquaculture waste is smooth.

[0046] A further optimized solution is that several connecting components between the float 11 at the top of the seedling box 1 and the float 11 at the top of the medium culture box 2 include a connecting pipe 5, both ends of the connecting pipe 5 are fixedly connected with a clamp tee 6, and the two clamp tees 6 are fixedly connected to the two floats 11 respectively.

[0047] like Figure 5 The structure of a clamp tee 6 is shown. The clamp side 61 of the clamp tee 6 is designed to be fixedly mounted on the floating body 11. A sleeve 62 that can be fixedly mounted on the connecting pipe 5 is provided on the outer wall of the clamp side.

[0048] To further optimize the solution, a plurality of pedals 7 are arranged between the float 11 at the top of the seedling box 1 and the float 11 at the top of the medium culture box 2, and between the float 11 at the top of the growing box 3 and the float 11 at the top of the medium culture box 2, and the two ends of the pedals 7 are fixedly connected to two adjacent connecting pipes 5 respectively.

[0049] like Figure 1As shown, a plurality of pedals 7 are spaced a certain distance apart, that is, laid in a discrete form, to form a feeding port 4, which can leave an operating space for feeding in the medium culture box 2 and the growing box 3. The pedal 7 can be fixed on the sea urchin culture cage by fixedly connecting the pedal with the connecting pipe 5, so that people can pass between the nursery box 1, the medium culture box 2 and the growing box 3, and the operability is strong.

[0050] Further optimizing the scheme, the inner side net 16, the inner bottom net 15, the middle side net 14, and the middle bottom net 13 respectively adopt a double-layer net structure;

[0051] The outer side net 10 and the outer bottom net 9 respectively adopt a single-layer net structure.

[0052] The outer nets of the inner side net 16, the inner bottom net 15, the middle side net 14, and the middle bottom net 13 are made of hard materials such as large mesh PET, and the inner layer is made of soft materials such as small mesh PE, which provide a matrix for the sea urchin larvae to attach to. The mesh of the inner net is smaller than the minimum specification of the cultured sea urchin. The outer side net 10 and the outer bottom net 9 are made of hard materials such as PET, and the mesh is smaller than the minimum specification of the cultured sea urchin.

[0053] To further optimize the solution, when the medium culture box 2 and the nursery box 1 are used as the growing box 3, they should be changed to a single-layer net structure.

[0054] The application process of this embodiment is as follows: During the sea urchin culture period, the sea urchin larvae are placed in the nursery box 1. After the juvenile galls are cultivated to 0.5 cm, the juvenile galls are moved from the nursery box to the medium culture box 2. In order to improve the survival rate of the sea urchins during the culture period, the sea urchins are cultivated in the medium culture box 2 to a size of not less than 2 cm and then moved to the culture box. During the culture period, the nets of the nursery box 1 and the medium culture box 2 can be taken out for cleaning and safety inspection.

[0055] Embodiment 2:

[0056] The difference between this embodiment and the first embodiment is that the outer side of the medium culture box 2 and the outer side of the seedling box 1 are respectively provided with non-contact anti-collision bodies 8, and two sets of anti-collision bodies 8 are respectively located between the medium culture box 2 and the growing box 3 and between the medium culture box 2 and the seedling box 1. The anti-collision bodies 8 are fixedly connected to the connecting tube 5 by a tether.

[0057] like Figure 2 As shown, annular anti-collision bodies 8 are horizontally arranged between the medium culture box 2 and the growing box 3 and between the medium culture box 2 and the nursery box 1. The anti-collision bodies 8 are located underwater to further ensure that no friction or collision occurs between the nets.

[0058] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
