Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a large yellow croaker farming device. Background Technology

[0002] Yellow croaker is an important species for aquaculture in my country's coastal waters. It is rich in nutrients and has a delicious flavor, making it popular with consumers. To meet the demand, seawater cages are now widely used for yellow croaker farming. However, existing seawater aquaculture cages often exist as individual units. During the aquaculture process, these cages are typically connected in sections. Connecting cages offers advantages such as improved resistance to wind and waves, unified operation, and equipment sharing. However, current cage connection structures are quite complex. For example, a spliced ​​seawater aquaculture cage disclosed in Chinese Patent Publication No. CN216492796U has a splicing structure including a limiting plate, fixing rod, spring, telescopic rod, sleeve plate, and sleeve. The large number of components in this splicing mechanism leads to higher production costs. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the large yellow croaker farming device includes a ring-shaped buoyancy plate 1, with a net 2 installed on the inner ring of the buoyancy plate 1, and also includes:

[0028] Notch 3 is located on the outer edge of the buoyancy plate 1 in a circumferential direction, and notch 3 is trapezoidal;

[0029] Connection hole 4 is located on the inner wall of notch 3;

[0030] Connecting block 5, in the shape of an hourglass, is used to mate with notch 3;

[0031] Groove 6 is provided on the outer wall of connecting block 5;

[0032] The elastic positioning post 7 is set on the connecting block 5 and is used to mate with the connecting hole 4;

[0033] Handle 8 is located on the top surface of connecting block 5.

[0034] The connecting block 5 can be engaged with the two notches 3 respectively, and then the elastic positioning post 7 is inserted into the connecting hole 4 to connect the two adjacent buoyancy plates 1, thereby realizing the connection between the cages. The structure is simple and the connection is convenient.

[0035] In the embodiments, such as Figure 2 , Figure 3 As shown, the elastic positioning post 7 is provided with connecting blocks 5 on both sides. The two sides of the connecting block 5 cooperate with the notch 3, making the connection between the connecting block 5 and the notch 3 more secure.

[0036] In the embodiments, such as Figure 2 , Figure 3 As shown, a sealing ring 9 is provided in the groove 6 for engagement with the elastic positioning post 7. The elastic positioning post 7 includes a post body and a spring, preventing seawater from entering the groove 6 and affecting the service life of the spring.

[0037] In the embodiments, such as Figure 4 As shown, the outer surface of the handle 8 is provided with anti-slip texture 10. It is not easy to slip when gripping the handle 8, making it easy to remove the connecting block 5 from the notch 3.

[0038] In the embodiments, such as Figure 5 As shown, the buoyancy plate 1 has a support rod 11 and a protective ring 12 on the top of the support rod 11 on the side near the net 2. The buoyancy plate 1 has a through hole for cooperating with the support rod 11. A limiting block 13 is provided on the outer side of the support rod 11, and a locking element 14 for cooperating with the support rod 11 is provided on the limiting block 13. The locking element 14 is a bolt. By pressing the support rod 11 with the bolt, the protective ring 12 can be installed on the buoyancy plate 1 to provide protection. When fishing is needed, the bolt is loosened to lower the protective ring 12 for easy fishing.

[0039] In the embodiments, such as Figure 1 , Figure 5As shown, a counterweight ring 15 is connected to the bottom of the net 2, and a rope pulley 16 is installed on the buoyancy plate 1. The rope pulley 16 is equipped with a power device 17, and a rope 18 for connecting the counterweight ring 15 is provided on the rope pulley 16. The rope 18 can be a nylon rope, and the power device 17 is a motor. By pulling the counterweight ring 15 upward, the net 2 can be lifted up, making it easier to catch yellow croaker.

[0040] In the embodiments, such as Figure 1 , Figure 5 As shown, the buoyancy plate 1 is also provided with a protective cover 19 for covering the rope pulley 16 and the power unit 17. The protective cover 19 prevents foreign objects from damaging the power unit 17 or the rope pulley 16.

[0041] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
