They are mainly composed of a frame system, nets, a fixing system, and supporting facilities. By utilizing the interaction of the fixed platform and the characteristics of the cage itself, the cage is lowered to a limited depth underwater. Cage aquaculture has the characteristics of low investment, high yield, mobility, and quick results, and is widely used in lakes and reservoirs in various regions.

[0003] During the transfer of fish from net cages to fishing boats, docking structures are needed to connect and assemble the net cages and fishing boats. If the docking is not properly positioned, it is easy for the docking to shift, affecting the transfer of fish and potentially causing the fish to squeeze each other, resulting in damage to the fish and affecting product quality.

[0009] As a further technical solution of this utility model, a second connecting groove is provided at the upper and lower positions of the side of the second connecting end, and the second connecting groove is symmetrically distributed about the central axis of the second connecting end.

[0010] As a further technical solution of this utility model, a first connecting groove is provided at the upper and lower positions of the side of the first connecting end, and the first connecting groove is symmetrically distributed about the central axis of the first connecting end.

[0011] As a further technical solution of this utility model, the second connecting groove is internally connected to the first connecting groove by a connecting bolt, and a cap is fixed to the end face of the connecting bolt.

[0012] As a further technical solution of this utility model, reinforcing components are evenly distributed in the first connecting end and the second connecting end. The reinforcing components include a first diagonal brace and a second diagonal brace, with the second diagonal brace connecting between the first diagonal brace.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this easy-to-position fishing boat cage docking structure not only improves the positioning capability, but also improves the docking convenience and strength of the docking structure.

[0014] (1) By assembling and fixing the positioning pins on the upper and lower positions of the sides of the main body of the net cage and the main body of the fishing boat, and opening slots in the sides of the main body of the net cage and the main body of the fishing boat, the slots are used for the assembly of the first connecting end and the second connecting end. For example, the first connecting end passes through the slot and is limited by the first positioning plate. At this time, the positioning pin is positioned by passing through the positioning hole. Then, the position is locked by the locking nut at the external thread end. The second connecting end is assembled in the same way. Hollow slots are opened in the center of the first positioning plate and the second positioning plate. When the water flow moves, the guide plate can be pushed to swing, which facilitates the guidance of the water flow. This improves the positioning effect during docking and prevents the phenomenon of docking offset.

[0015] (2) By opening the first flow groove in the middle position of the first connecting end and opening the second flow groove in the center position of the second connecting end, the first connecting end is assembled from the inner side of the main body of the cage during connection, while the second connecting end is assembled from the side of the first positioning plate. Then, the first connecting end is inserted into the second flow groove until the vertical positions of the first connecting groove and the second connecting groove coincide. After rotating the cap, the connecting bolts are used to lock the connection, which improves the overall docking convenience during the operation.

[0016] (3) By uniformly distributing reinforcing components in the solid areas of the first and second connecting ends, and the reinforcing components being composed of a first diagonal brace and a second diagonal brace, the first diagonal brace is evenly distributed and the connection between the first diagonal brace is completed by the second diagonal brace. Therefore, during the use of the first and second connecting ends, the overall strength is improved and the deformation problem is reduced. Attached Figure Description
