A side net 10 is arranged at the bottom of the bottom frame 1. The top frame 2 is arranged on the top of the bottom frame 1. The opposite sides of the top frame 2 and the bottom frame 1 are connected by the side net 10. Slots two 17 are respectively arranged at the four corners of the bottom of the top frame 2. A cavity 9 is arranged inside the top frame 2. A slot one 16 is arranged at the center of the front side of the cavity 9. The number of support columns 8 is four. The bottom ends of the four support columns 8 are respectively hinged inside the active slot one 4 and the active slot two 5. The sealing frame 11 is hinged to the rear side of the cavity 9. A top net 12 is arranged inside the sealing frame 11. An inner cavity 13 is arranged on the front side of the sealing frame 11. A sliding slot 14 is arranged at the top of the inner cavity 13. The quick-release structure 15 is arranged inside the inner cavity 13.

[0031] Embodiment 2:

[0032] Next, the solution in Embodiment 1 will be further introduced in combination with the specific working mode, as detailed in the following description: Limiting shafts one 6 are arranged inside the two active slots one 4, and limiting shafts two 7 are arranged inside the two active slots two 5. The two limiting shafts one 6 and the limiting shafts two 7 are not in the same plane. Active slots three 18 are respectively arranged inside the four support columns 8. The four active slots three 18 are respectively adapted and connected to the limiting shafts one 6 and the limiting shafts two 7. The four support columns 8 can be completely received inside the through cavities 3. Four groups of limiting structures (which belong to the prior art and are not shown in the figure) for preventing the support columns 8 from sliding out are respectively arranged on the separated sides of the two active slots one 4 and the active slots two 5. The top ends of the four support columns 8 are respectively adapted and connected to the slots two 17. Chute grooves are respectively arranged on both sides of the separated sides of the two active slots one 4 and the active slots two 5. Each group of limiting structures includes a limiting plate. Sliding blocks are respectively fixedly connected to both sides of the limiting plate. The two sliding blocks are respectively adapted and connected to the chute grooves.

[0033] Then, the support columns 8 are respectively folded and transported into the through cavities 3 to complete the storage of the support columns 8, reducing the risk of loss of the support columns 8. The structure is simple, and the working efficiency of the staff in disassembling and installing the net cage is increased.

[0034] Embodiment 3:

[0035] The scheme in Example 2 is further introduced below in combination with the specific working method, as described below for details: the quick-release structure 15 includes a telescopic rod 1501, a spring 1502, a trapezoidal block 1503, a connecting block 1504 and a toggle block 1505, and telescopic rods 1501 are respectively provided on both sides of the rear part of the inner cavity 13, one end of the two telescopic rods 1501 is respectively fixedly connected to the inside of the inner cavity 13, and the other end is fixedly connected to the trapezoidal block 1503, the outer walls of the two telescopic rods 1501 are respectively sleeved with springs 1502, the top of the rear side of the trapezoidal block 1503 is fixedly connected to the connecting block 1504, the top of the connecting block 1504 passes through the sliding groove 14 and is fixedly connected to the toggle block 1505, the trapezoidal block 1503 is adaptably connected to the slot 16, and the connecting block 1504 is adaptably connected to the sliding groove 14.

[0036] A detachable sealing frame 11 is provided. By pushing the toggle block 1505 backward, the trapezoidal block 1503 is driven to retract into the inner cavity 13 and squeeze the telescopic rod 1501 and the spring 1502, thereby breaking away from the limit of the slot 16, and the sealing frame 11 can be folded. The structure is simple. When closed, the sealing frame 11 and the top frame 2 can be connected by the cooperation of the telescopic trapezoidal block 1503 and the slot 16, thereby avoiding the problem of sea bass jumping out of the net cage during the breeding process.

[0037] When in use, first open the limiting structure, pull out the four support columns 8 respectively, and then fold the four support columns 8 so that the top ends of the support columns 8 are inserted into the slot 2 17. The support columns 8 are limited by the top inner walls of the movable slot 1 4 and the movable slot 2 5, thereby preventing the support columns 8 from being squeezed toward the side net 10. Then, push the toggle block 1505 backward to drive the trapezoidal block 1503 to shrink into the inner cavity 13 and squeeze the telescopic rod 1501 and the spring 1502, thereby disengaging from the limit of the slot 16. Then, the sealing frame 11 can be folded and the sea bass to be farmed can be put into the net cage. When closing, the telescopic trapezoidal block 1503 cooperates with the slot 1 16 to complete the connection between the sealing frame 11 and the top frame 2, thereby preventing the sea bass from jumping out of the net cage during the breeding process.
