Description

Technical Field

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

[0002] Aquaculture cages are fish cages made of fishing nets and placed in the sea to cultivate seafood products. Aquaculture cages have abandoned the drawbacks of traditional aquaculture methods, making deep-sea aquaculture industry a development hotspot. According to the hydrological characteristics of my country's coastal waters and the basic situation of marine aquaculture, my country's deep-sea aquaculture generally refers to open waters 3 nautical miles offshore, with a water depth of 25m to 100m, and no shelter. It is an industrialized marine aquaculture production method that is guaranteed by remote control facilities and equipment, supported by land and sea supply systems, and has no negative impact on the ecological environment.

[0003] For example, Chinese patent publication number CN204949094U discloses a breeding cage, comprising an inner floating tube, an outer floating tube, a bracket and a net, wherein the inner floating tube and the outer floating tube are fixed together by the bracket, and the upper part of the net is fixed on the inner floating tube or the outer floating tube. The cage also comprises a plurality of nets and a support ring, wherein the upper end of the net is connected to the bracket, and the support ring is fixed to the lower end of the net, and the side of the net is connected to the net and the bottom of the net is located above the support ring.

[0004] However, in the above scheme, when the farmed fish need to be salvaged, it is not convenient to quickly catch the fish in the cage, and fishing tools need to be used for fishing, which has low fishing efficiency and low convenience. Utility Model Content

[0008] As a further improvement of the present technical solution: the fishing device includes a driving motor, which is fixedly connected to the top side wall of the top plate, and the output shaft of the driving motor passes through the side wall of the top plate and is rotatably connected to the top plate, the output shaft of the driving motor is fixedly connected to a threaded rod, the bottom of the threaded rod is rotatably connected to the top side wall of the bottom plate, and a fishing net is threadedly connected to the outer ring side wall of the threaded rod.

[0009] As a further improvement of the technical solution: the threaded rod and the fishing net are both made of stainless steel.

[0010] As a further improvement of the technical solution: a protective mesh cover is fixedly connected to the side wall of the outer ring of the frame, and the rectangular airbag is located inside the protective mesh cover.

[0011] As a further improvement of the technical solution: reinforcing rods are fixedly connected to the side walls around the frame.

[0012] As a further improvement of the technical solution: the pull rope is made of stainless steel.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the device can quickly catch all the fish in the net cage when it is needed to catch fish through the mutual cooperation of the fishing net, threaded rod, driving motor, reinforcing rod and other components, avoiding fish residue in the water tank, greatly improving the fish catching efficiency, and the operation is simple, convenient and fast.

[0025] See also Figure 1-4In an embodiment of the utility model, a breeding net cage includes a frame 1, which is arranged in a rectangular parallelepiped shape, and a net body 16 is arranged on the four sides and bottom side walls of the frame 1. A bottom plate 7 is fixedly connected to the bottom of the frame 1, and two fixed blocks 8 are fixedly connected to the bottom side walls of the bottom plate 7. A rotating shaft 9 is rotatably connected between the two fixed blocks 8, and a pull rope 10 is wound and connected on the outer ring side wall of the rotating shaft 9. The pull rope 10 is made of stainless steel, and an anchor block 11 is arranged at one end of the pull rope 10. A stepper motor 12 is fixedly connected to the bottom side wall of the bottom plate 7, and one end of the rotating shaft 9 passes through one of the fixed blocks 8 and is fixedly connected to the output shaft of the stepper motor 12. A rectangular air bag 4 is arranged on the outer ring side wall of the frame 1, and an inflation nozzle 6 is arranged on the top of the rectangular air bag 4. A top plate 15 is fixedly connected to the top side wall of the frame 1, and a fishing device is arranged at the bottom of the frame 1.

[0026] See also Figure 1-3 The fishing device includes a driving motor 14, which is fixedly connected to the top side wall of the top plate 15. The output shaft of the driving motor 14 passes through the side wall of the top plate 15 and is rotatably connected to the top plate 15. The output shaft of the driving motor 14 is fixedly connected to a threaded rod 13. The bottom of the threaded rod 13 is rotatably connected to the top side wall of the bottom plate 7. A fishing net 3 is threadedly connected to the outer side wall of the threaded rod 13. When it is necessary to catch the fish in the frame 1, the driving motor 14 is started, and the output shaft of the driving motor 14 drives the threaded rod 13 to rotate. The threaded rod 13 can drive the fishing net 3 to move up and down when rotating. By starting the driving motor 14, the fishing net 3 is moved upward. The fishing net 3 can catch all the fish in the frame 1 on the fishing net 3 when it moves, and then the fish on the fishing net 3 can be removed.

[0027] See also Figure 1 The threaded rod 13 and the fishing net 3 are both made of stainless steel, which increases the hardness of the fishing net 3 and prevents the threaded rod 13 and the fishing net 3 from being affected by rust.

[0028] See also Figure 1-3 A protective net cover 5 is fixedly connected to the outer side wall of the frame 1, and the rectangular airbag 4 is located in the protective net cover 5. The protective net cover 5 can be used to protect the rectangular airbag 4 to prevent fish and shrimp in the sea from damaging the rectangular airbag 4.

[0029] See also Figure 1-2 , Figure 4 The frame 1 is fixedly connected to the side walls thereof with reinforcing rods 2, which can enhance the stability of the frame 1. When strong winds and waves come, the frame 1 will not be deformed.

[0030] The working principle of the utility model is as follows: first, the rectangular airbag 4 is inflated through the inflation nozzle 6. After the inflation is completed, the entire net cage is placed into the sea. The rectangular airbag 4 drives the entire net cage to float on the sea surface. By starting the stepper motor 12, the output shaft of the stepper motor 12 drives the rotating shaft 9 to rotate. The rotating shaft 9 can reel in or release the pull rope 10 during rotation, thereby driving the anchor block 11 to move up and down through the pull rope 10. By starting the stepper motor 12, the anchor block 11 moves downward and sinks to the seabed. When the sea breeze blows the frame 1 to move, the anchor block 11 will be stuck in the soil on the seabed, thereby fixing the frame 1, and then the fish are placed in the frame 1 for breeding.

[0031] When it is necessary to catch the fish in the frame 1, the driving motor 14 is started, and the output shaft of the driving motor 14 drives the threaded rod 13 to rotate. The threaded rod 13 can drive the fishing net 3 to move up and down when rotating. By starting the driving motor 14, the fishing net 3 is moved upward, and the fishing net 3 can catch all the fish in the frame 1 on the fishing net 3 during movement, and then the fish on the fishing net 3 can be removed. After the fishing is completed, the driving motor 14 is started to move the fishing net 3 downward to the bottom of the frame 1, and other fish can be cultured.

[0032] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
