The telescopic mechanism 30 is configured to drive the bottom of the cage body 20 to move toward or away from the open end of the cage body 20 to achieve the switching of the cage body 20 between the net-collecting state and the net-extending state.

[0037] According to the aquaculture cage 100 disclosed in the present invention, the aquaculture cage 100 includes a buoy body 10, a cage body 20 and a telescopic mechanism 30, wherein the open end of the cage body 20 is connected to the buoy body 10, and the telescopic mechanism 30 can drive the bottom of the cage body 20 to move toward the open end of the cage body 20, as the bottom of the cage body 20 gradually moves toward the open end to the extreme position, the telescopic mechanism 30 no longer drives the bottom of the cage body 20 to move, and at this time, the cage body 20 is in a net-closing state; the telescopic mechanism 30 can drive the bottom of the cage body 20 to move away from the open end of the cage body 20, as the bottom of the cage body 20 gradually moves away from its open end to the extreme position, the telescopic mechanism 30 no longer drives the bottom of the cage body 20 to move, and at this time, the cage body 20 is in a net-stretching state. The aquaculture cage 100 of this embodiment can control the net-collecting state and the net-expanding state of the cage body 20 through the telescopic mechanism 30, which can improve the working efficiency of the aquaculture cage 100 in collecting and releasing the net, improve the efficiency of deep-sea aquaculture, and further improve the economic benefits of deep-sea aquaculture. At the same time, it can also reduce the workload of workers engaged in artificial purse seine fishing.

[0038] In some embodiments of the present disclosure, the buoy body 10 is an annular structure, and the open end of the cage body 20 is connected to the outer side of the inner ring side wall 11 of the annular structure. The buoy body 10 has a certain thickness along the axial direction of the buoy body 10 of the annular structure, and the cage body 20 is connected to the outer side of the inner ring side wall 11 of the buoy body 10, that is, the cage body 20 is arranged on the inner side of the buoy body 10, and the buoy body 10 forms an annular protective barrier on the outer side of the circumference of the cage body 20. The buoy body 10 can block part of the marine garbage or other pollutants for the cage body 20, so as to reduce the damage caused by marine garbage or other pollutants to the cage body 20 and improve the service life of the cage body 20.

[0039] Furthermore, the buoy body 10 includes an outer ring side wall 12, an inner ring side wall 11, a top plate 13 and a bottom plate (not shown in the figure), wherein the outer ring side wall 12, the inner ring side wall 11, the top plate 13 and the bottom plate are all annular plate structures. The two ends of the inner ring side wall 11 are respectively connected to the inner ring of the top plate 13 and the inner ring of the bottom plate, and the two ends of the outer ring side wall 12 are respectively connected to the outer ring of the top plate 13 and the outer ring of the bottom plate.

[0040] Specifically, multiple connection points at the open end of the cage body 20 are connected to the outer side of the inner ring side wall 11 of the annular buoy body 10 through the cable 40, so that the open end of the cage body 20 is in an open state. Further, multiple connection points are spaced and evenly arranged at the open end of the cage body 20 along the circumference of the open end of the cage body 20 to ensure that the open end of the cage body 20 is subjected to a relatively uniform force. At the same time, when multiple connection points are connected to the outer side of the inner ring side wall 11 of the buoy body 10, multiple connection points are evenly and spacedly distributed at the outer side of the inner ring side wall 11 of the buoy body 10 to ensure that the inner ring of the buoy body 10 is subjected to a relatively uniform force.

[0041] Specifically, in this embodiment, there are six connection points at the open end of the cage body 20, and the six connection points are spaced and evenly arranged along the circumference of the open end of the cage body 20. The cage body 20 is connected to the inner ring of the buoy body 10 of the ring structure through the six connection points at its open end, and the six connection points make the open end of the cage body 20 form a regular hexagonal structure. In other disclosed embodiments, the number of connection points is at least three or more, and specifically, the number of connection points can also be three, four, five, seven, eight, nine, ten or more than ten. This embodiment does not impose a specific limitation on the specific number of connection points, and those skilled in the art can set them according to actual needs, as long as the open end of the cage body 20 can be guaranteed to be in an open state.

[0042] In this embodiment, the buoy body 10 can be a square ring, an elliptical ring, a triangular ring, a circular ring or other polygonal ring structures. In this embodiment, in order to make the buoy body 10 more uniform in all directions, the circular ring buoy body 10 is used as the preferred solution.

[0043] In some embodiments of the present disclosure, the outer side of the bottom of the buoy body 10 is provided on the heave plate 15, that is, the outer ring of the bottom plate of the buoy body 10 is provided on the heave plate 15. The additional mass and damping coefficient of the annular structure of the buoy body 10 can be increased through the heave plate 15, thereby improving the damping and natural vibration period of the buoy body 10.

[0044] Specifically, the heave plate 15 is arranged along the circumference of the buoy body 10, and the heave plate 15 is formed by the buoy body 10 extending in the direction away from the buoy body 10. The heave plate 15 forms a ring along the circumference of the buoy body 10. Specifically, the heave plate 15 can be a plate body with an annular structure, the inner ring of the heave plate 15 with an annular structure is connected to the outer ring side wall 12 of the buoy body 10, and the inner ring of the heave plate 15 with an annular structure is connected to the bottom plate of the buoy body 10, that is, the connection between the outer ring side wall 12 of the buoy body 10 and the bottom plate of the buoy body 10 is connected to the inner ring of the heave plate 15 with an annular structure; the heave plate 15 can also be a plurality of block-shaped plate bodies, the plurality of block-shaped plate bodies are respectively connected to the outer side of the outer ring side wall 12 of the buoy body 10, the plurality of block-shaped plate bodies are spaced and evenly distributed on the outer side of the outer ring side wall 12 of the buoy body 10, and each block-shaped plate body is connected to the bottom plate of the buoy body 10.

[0045] In some embodiments of the present disclosure, the telescopic mechanism 30 is disposed through the buoy body 10. Specifically, the telescopic mechanism 30 is disposed through the buoy body 10 along the axial direction of the buoy body 10, that is, the telescopic mechanism 30 can be telescoped along the axial direction of the buoy body 10, that is, the telescopic mechanism 30 drives the bottom of the net box body 20 to move toward or away from the exit end to control the net box body 20 to switch between the net collecting state and the net extending state.

[0046] In some embodiments of the present disclosure, the telescopic mechanism 30 includes: a driving motor 31 and a telescopic member 32. Specifically, the driving motor 31 is connected to the buoy body 10, and the driving motor 31 is connected to the telescopic member 32, so that the driving motor 31 can drive the telescopic member 32 to move along the axial direction of the buoy body 10. One end of the telescopic member 32 is connected to the bottom of the net cage body 20. When the driving motor 31 drives the telescopic member 32 to move along the axial direction of the buoy body 10, one end of the telescopic member 32 drives the net cage body 20 to move along the axial direction of the buoy body 10, so that the bottom of the net cage body 20 moves toward or away from its opening end, thereby realizing the net cage body 20 to close or open the net.

[0047] Specifically, the driving motor 31 can be connected to the top, the outer ring side wall 12 or the bottom of the buoy body 10. When the driving motor 31 is arranged on the outer ring side wall 12 of the buoy body 10 or the bottom of the buoy body 10, the marine debris or pollutants in the seawater may hit the outer ring side wall 12 of the buoy body 10 or the bottom of the buoy body 10 while drifting with the seawater, thereby causing damage to the driving motor 31. Therefore, in this embodiment, the driving motor 31 is arranged on the top of the buoy body 10 as a preferred solution.

[0048] In some embodiments of the present disclosure, the telescopic member 32 is in an "L"-shaped structure, and the vertical rod 321 of the telescopic member 32 of the "L"-shaped structure is connected to the horizontal rod 322 of the telescopic member 32 of the "L"-shaped structure. The driving motor 31 is drivingly connected to the vertical rod 321 of the "L"-shaped structure. Specifically, a rack 323 is provided on the vertical rod 321 of the telescopic member 32 of the "L"-shaped structure, and a gear 311 is provided at the output end of the driving motor 31. The gear 311 at the output end of the driving motor 31 is meshedly connected with the rack 323 on the telescopic member 32, thereby ensuring that the driving motor 31 can drive the telescopic member 32 to move.

[0049] The cross bar 322 of the "L"-shaped structure is connected to the bottom of the cage body 20. Specifically, the cross bar 322 of the "L"-shaped structure is connected to the edge of the bottom net 22 of the cage body 20. The movement of the cross bar 322 of the "L"-shaped structure drives the bottom net 22 of the cage body 20 to move, thereby changing the breeding space of the cage body 20, and further realizing the switching between the net-closing state and the net-stretching state of the cage body 20. Furthermore, the end of the cross bar 322 of the "L"-shaped structure that is away from the vertical bar 321 of the "L"-shaped structure is oriented toward the cage body 20 to reduce the distance between the cage body 20 and the telescopic member 32, thereby reducing the deformation of the cage body 20 and improving the service life of the cage body 20.

[0050] Furthermore, the cross bar 322 of the telescopic member 32 also has a limiting function. Specifically, a through hole is provided on the buoy body 10, and the axis of the through hole is parallel to the axial direction of the buoy body 10. The vertical rod 321 of the telescopic member 32 is penetrated in the buoy body 10 through the through hole. Along the axial direction of the buoy body 10, the size of the through hole is smaller than the size of the cross bar 322, that is, the cross bar 322 cannot pass through the through hole. When the driving motor 31 drives the telescopic member 32 to move toward the open end of the net cage body 20, the vertical rod 321 of the telescopic member 32 moves in the through hole, and the vertical rod 321 drives the cross bar 322 to move. When the cross bar 322 moves to contact with the bottom plate of the buoy body 10, the bottom plate limits the cross bar 322 from continuing to move, that is, the bottom plate limits the telescopic rod from continuing to move. At this time, the position of the bottom net 22 is the limit position of the net-closing state.

[0051] In addition, a limit portion can be set at the top or upper part of the vertical rod 321 of the telescopic member 32 to limit the position of the telescopic member 32 when it moves away from the open end of the net box body 20. When the limit portion of the telescopic rod contacts the drive motor 31, or when the limit portion of the telescopic rod contacts the top plate 13, the drive motor 31 or the top plate 13 limits the telescopic rod from continuing to move. At this time, the position of the bottom net 22 is the extreme position of the net-stretching state.

[0052] In some embodiments of the present disclosure, the telescopic mechanism 30 includes two drive motors 31, and the two drive motors 31 are symmetrically arranged on both sides of the telescopic member 32. Specifically, the two motors respectively drive the vertical rod 321 connected to the telescopic member 32, which can further provide the reliability of the telescopic mechanism 30. When one motor fails, the other motor can drive the telescopic member 32 to continue to move. The two drive motors 31 are arranged on opposite sides of the telescopic member 32, so that the force on both sides of the telescopic member 32 is more uniform.

[0053] In some embodiments of the present disclosure, there are multiple groups of telescopic mechanisms 30, and the multiple groups of telescopic mechanisms 30 are spaced and evenly arranged along the circumference of the buoy body 10. Specifically, the crossbars 322 of the telescopic members 32 of each group of telescopic mechanisms 30 are connected to the edges of the bottom net 22 of the cage body 20 through the cables 40, and the multiple telescopic members 32 are spaced and evenly arranged along the circumference of the bottom net 22, so that the cage body 20 is more evenly stressed.

[0054] Furthermore, the number of telescopic mechanisms 30 is six groups, that is, six telescopic members 32 are spaced and evenly arranged along the axial direction of the buoy body 10. The six groups of telescopic mechanisms 30 are arranged one by one corresponding to the six connection points of the net body, so as to reduce the deformation of the net cage body 20 during the net stretching process, thereby improving the service life of the net cage body 20.

[0055] In some embodiments of the present disclosure, the cage body 20 includes a side net 21 and a bottom net 22, and the side net 21 is connected to the bottom net 22 to form an open breeding space. Specifically, the first end of the side net 21 is connected to the outer side of the inner side wall of the buoy body 10 to connect the cage body 20, and the first end of the side net 21 forms the open end of the cage body 20. The second end of the side net 21 is connected to the bottom net 22, and the outer side of the bottom net 22 is connected to the telescopic mechanism 30. The telescopic mechanism 30 drives the outer side of the bottom net 22 to move along the axial direction of the buoy body 10, so that the bottom net 22 moves toward or away from the opening end of the cage body 20. Even if the bottom net 22 drives the second end of the side net 21 toward or away from the first end of the side net 21, as the distance between the second end of the side net 21 and the first end of the side net 21 decreases, the breeding space between the side net 21 and the bottom net 22 decreases. At this time, the cage body 20 is collecting the net; as the distance between the second end of the side net 21 and the first end of the side net 21 increases, the breeding space between the side net 21 and the bottom net 22 increases. At this time, the cage body 20 is spreading the net.

[0056] Furthermore, the side net 21 includes six side wall nets 211 , which have the same structure and size. The six side wall nets 211 form the side net 21 , and along the axial direction of the buoy body 10 , the cross-section of the side net 21 is a hexagonal structure.

[0057] It should be noted that the outer side of the inner ring side wall 11 of the buoy body 10 in this embodiment refers to the side of the inner ring side wall 11 away from the outer ring side wall 12 , and the outer side of the outer ring side wall 12 of the buoy body 10 refers to the side of the outer ring side wall 12 away from the inner ring side wall 11 .

[0058] In this embodiment, when the aquaculture cage 100 is delivered by launching at the dock, the cage body 20 is controlled to be in the net-collecting state to reduce the requirements for the dock draft when the aquaculture cage 100 is built, ensuring that the aquaculture cage 100 can be built at most docks, and reducing the construction cost of the aquaculture cage 100. When the aquaculture cage 100 is towed, the cage body 20 is controlled to be in the net-collecting state to reduce the contact area between the cage body 20 and the seawater, thereby reducing the towing resistance of the aquaculture cage 100 during the towing process, thereby reducing the towing cost, and at the same time, reducing the damage to the net body caused by garbage or other items in the seawater during the towing process. When the aquaculture cage 100 is in the aquaculture state, the cage body 20 is controlled to be in the net-spreading state to increase the aquaculture space of the cage body 20 and improve the aquaculture efficiency.

[0059] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
