The upper part of the base is connected to the vertical rod, and the vertical rods are arranged in a circumferential array on the upper part of the base. One end of the reinforcing rib is connected to the vertical rod, and the other end of the reinforcing rib is connected to the base; the upper part of the vertical rod is connected to the pedal, and the inner side of the pedal has a plurality of support blocks. The inside of the support block has a hook hole, and the outside of the aquaculture box has a hook, and the hook is inserted into the hook hole, and the aquaculture box is stuck on the support block; the aquaculture box is composed of an outer frame and a retaining net. A plurality of rings are connected to the inside of the outer frame, and the upper part of the aquaculture box has a positioning groove, and a positioning column is arranged inside the positioning groove.

[0004] In the existing new type of aquaculture cage device, a base, a vertical rod, and a reinforcing rib are designed. The vertical rod is equivalent to the fishing net support member, and the reinforcing rib locally strengthens between the vertical rod and the base. However, due to the long-term repeated impact of seawater on the fishing net, the connection part between the fishing net support member and the deck or bulkhead plate is a high-stress area. Under the action of variable external loads, cracks are likely to appear at the welded joint of the fishing net support member and the deck or bulkhead plate, the fatigue strength is poor, and the reliability is low.

[0030] Such as Figures 1 to 4As shown in the figure, a net support structure for a marine ranch according to an embodiment of the present utility model includes a base plate 1, a net support member 2, a fixed support 3, a first reinforcement structure 4, and a second reinforcement structure 5. The net support member 2 and the fixed support 3 are both arranged on one side surface of the base plate 1. An installation hole 34 is formed in the middle of the fixed support 3, and the net support member 2 is inserted and fixed in the installation hole 34. The fixed support 3 includes a plurality of lateral support portions 30, and the plurality of lateral support portions 30 are arranged at circumferential intervals with respect to the installation hole 34. The first reinforcement structure 4 is fixedly connected between the net support member 2 and the lateral support portion 30, and the second reinforcement structure 5 is fixedly arranged on the other side surface of the base plate 1, and the second reinforcement structure 5 is arranged opposite to the fixed support 3.

[0031] This net support structure for a marine ranch adopts the design form of a base plate 1, a net support member 2, a fixed support 3, a first reinforcement structure 4, and a second reinforcement structure 5. The base plate 1 can be a deck or a bulkhead plate. The net support member 2 and the fixed support 3 are both arranged on one side surface of the base plate 1. An installation hole 34 is formed in the middle of the fixed support 3, and the net support member 2 is inserted and fixed in the installation hole 34. The net support member 2 is fixedly connected to the base plate 1 through the fixed support 3. Moreover, the plurality of lateral support portions 30 of the fixed support 3 are arranged at circumferential intervals with respect to the installation hole 34, and the plurality of lateral support portions 30 increase the connection strength between the net support member 2 and the base plate 1, ensuring the stability of lateral force.

[0032] Among them, the first reinforcement structure 4 is fixedly connected between the net support member 2 and the lateral support portion 30. The first reinforcement structure 4 can increase the connection strength between the net support member 2 and the lateral support portion 30, avoiding fatigue cracks caused by the net support member 2 being subjected to lateral loads, and further ensuring the fatigue strength of the net support member 2. The second reinforcement structure 5 is fixedly arranged on the other side surface of the base plate 1, and the second reinforcement structure 5 plays a role in strengthening the plate surface on the back of the base plate 1, improving the stress stability of the base plate 1. Even if the seawater repeatedly impacts the net for a long time, under the action of variable external loads, it effectively prevents cracks from appearing at the welded joints between the net support member 2 and the deck or bulkhead plate, and has higher fatigue strength and reliability.

[0036] It should be noted that a first notch 33 is provided on the inner side of the vertical support plate 31 corresponding to the lower end of the fishing net support 2. The first notch 33 is used to avoid the weld between the fishing net support 2 and the base plate 1. A second notch 43 is provided on the inner side of the triangular rib plate 41 corresponding to the connection between the fishing net support 2 and the side panel 32. The second notch 43 is used to avoid the weld between the fishing net support 2 and the side panel 32. The lower end of the fishing net support 2 is welded to the base plate 1, and the fishing net support 2 is also welded to the side panel 32 of the fixed support 3, increasing the area of the welded connection and effectively improving the support strength.

[0037] In addition, the second strengthening structure 5 is a grid-shaped strengthening structure, which includes a transverse rib plate 51 and a longitudinal rib plate 52 that are perpendicularly connected. One side edge of the transverse rib plate 51 and one side edge of the longitudinal rib plate 52 are respectively fixedly connected to the other side surface of the base plate 1. Moreover, the second strengthening structure 5 is arranged in central symmetry about the center of the fishing net support 2, and the outer peripheral contour of the second strengthening structure 5 is greater than or equal to the outer peripheral contour of the fixed support 3. The second strengthening structure 5 strengthened by the grid can enhance the structural strength of the base plate 1 and prevent problems such as deformation or cracking due to local stress.

It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
