Description

Technical Field

[0001] The utility model relates to the technical field of marine product breeding, in particular to a marine product breeding net cage. Background Art

[0002] Seafood cages are special equipment used to culture seafood (such as fish, shellfish, crustaceans, etc.) in waters such as oceans, lakes or large rivers. Cage culture is a modern aquaculture method that provides a relatively independent and controllable growth environment for cultured organisms by artificially setting up cages, thereby improving aquaculture efficiency, reducing environmental pollution and ensuring the quality of seafood.

[0003] In the traditional breeding process, feed needs to be thrown into the breeding cage. However, after the aquatic pellet feed is soaked in water for a period of time, some components in the feed are unstable in water, causing the pellets to dissolve easily. When fish and other seafood cannot ingest it in time, part of the feed will overflow through the holes in the cage under the influence of wind, waves, water flow and other factors, and will be lost to the outside of the cage and swallowed by wild fish, causing great waste. In order to ensure that the feed can be ingested by the cultured organisms more accurately, we propose a seafood breeding cage. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 The utility model provides a technical solution for a marine product breeding cage: comprising an outer box barrel 1 and an inner box barrel 2 which are arranged in close contact with each other, the outer box barrel 1 is used for breeding marine products, the outer box barrel 1 and the inner box barrel 2 are rotatably connected, the outer box barrel 1 is provided with a driving member connected with the inner box barrel 2, the upper part of the outer box barrel 1 is provided with a crossbeam, the driving member is arranged on the crossbeam, and is used to provide power for the rotation of the inner box barrel, the outer box barrel 1 and the inner box barrel 2 are respectively evenly distributed with mesh A and mesh B, and under normal conditions, mesh A and mesh B are connected one by one;

[0029] When mesh A and mesh B are connected, mesh A and mesh B form a water inlet for the flow of seawater inside and outside the cage, ensuring the fluidity of seawater inside the cage and outside seawater, helping to discharge harmful substances (such as ammonia nitrogen, hydrogen sulfide, etc.) in the water body out of the cage in time to reduce pollution, while bringing in fresh water to keep the water fresh, and at the same time reducing the accumulation of pathogens in the cage and reducing the risk of disease in cultured organisms;

[0030] When mesh A and mesh B are staggered, the cage forms a barrel with a closed circular outer wall to block the feed inside the cage and prevent the feed from overflowing through the holes in the cage and being lost to the outside of the cage and being eaten by wild fish due to factors such as wind, waves and water flow when fish and other seafood cannot be ingested in time.

[0031] When feeding the fish, the inner box barrel 2 is rotated so that the mesh A and the mesh B are staggered, that is, each mesh A is not connected with any mesh B, so as to block the feed in the net cage. After the fish feeding is completed, the inner box barrel 2 is continued to be rotated so that each mesh A is connected with the corresponding mesh B to ensure the fluidity of the seawater in the net cage and the external seawater.

[0032] Specifically, a cavity that is compatible with the inner barrel 2 is formed in the side wall of the outer barrel 1. The inner barrel 2 rotates in the cavity to prevent the rotation of the inner barrel 2 from causing damage to seafood such as fish. A fine-pore steel mesh is provided on the inner wall of the outer barrel 1 to prevent seafood pups from escaping from the outside of the outer barrel 1 through mesh A and mesh B.

[0033] Specifically, the driving member includes a ring gear 31, which is fixedly connected to the top of the inner barrel 2. The top of the ring gear 31 is provided with teeth. The ring gear 31 is engaged with a gear 32 connected to an external motor. The external motor is fixed on the cross beam. The output end of the external motor is fixedly connected to the gear 32. The output end of the external motor can drive the gear 32 to rotate, thereby causing the ring gear 31 to drive the inner barrel 2 to rotate.

[0034] Specifically, the driving member can also include an electric cylinder 33 arranged on the upper part of the outer barrel 1, the electric cylinder 33 is fixed on the crossbeam, and a two-link assembly 34 is rotatably assembled between the electric cylinder 33 and the inner barrel 2. The telescopic rod of the electric cylinder 33 can drive the two-link assembly 34 to move, thereby rotating the inner barrel 2. A limit groove is provided on the inner barrel 2, and a limit block sliding in the limit groove is provided on the outer barrel 1. The rotation range of the inner barrel 2 can be limited by the set limit groove and the limit block to ensure that the inner barrel 2 can block the mesh on the outer barrel 1 when feeding feed.

[0035] Specifically, the two-link assembly 34 includes a first link 341 and a second link 342. The first link 341 is rotatably connected to the second link 342. The first link 341 is fixedly connected to the output end of the electric cylinder 33. The second link 342 is rotatably connected to the inner barrel 2. The output end of the electric cylinder 33 can drive the first link 341 to move in a straight line. As the first link 341 moves, the second link 342 can drive the inner barrel 2 to rotate.

[0036] Specifically, an oxygen pump 4 is provided on the upper part of the outer box barrel 1 , and the oxygen pump 4 is fixed on the crossbeam. An oxygen component 5 is provided at the bottom of the outer box barrel 1 to realize oxygenation of the space inside the outer box barrel 1 .

[0037] Specifically, the oxygenation component 5 includes an aeration plate 51, which is integrally formed with the inner wall of the outer box barrel 1. An oxygenation channel 53 is formed between the aeration plate 51 and the bottom of the outer box barrel 1. Oxygenation holes 52 are distributed on the aeration plate 51. The oxygenation pump 4 is connected to the oxygenation channel 53 through an air pipe. By starting the oxygenation pump 4, oxygen can be supplied to the oxygenation channel 53 and transported to the outer box barrel 1 through the oxygenation holes 52. That is, a check valve is penetrated through the aeration plate 51, and the check valve is arranged at the air inlet of the oxygenation channel 53. The check valve can prevent water in the outer box barrel 1 from flowing back into the air pipe.

[0038] Specifically, a bottom ring 6 is integrally formed at the bottom of the outer wall of the outer box barrel 1, and a boss 7 is integrally formed at the upper part of the outer wall of the outer box barrel 1. A blocking component connected to the bottom ring 6 is provided on the boss 7. The boss 7 is used to limit the blocking component. By providing a blocking component, it is possible to prevent fish farmed in seawater from being attacked by large marine fish, and at the same time prevent the cage from being damaged or deformed due to wind, waves, collisions and other factors.

[0039] Specifically, the blocking assembly includes a mounting ring 81 which is sleeved on the outer wall of the outer box barrel 1. The mounting ring 81 abuts against the outer wall of the boss 7. A blocking rod 82 is fixedly connected between the mounting ring 81 and the boss 7. A slot for inserting the blocking rod 82 is provided on the bottom ring 6, so that the blocking rod 82 will be more stable. The blocking rod 82 is vertically arranged around the outer box barrel 1 to protect the outer box barrel 1.
