Description

Technical Field

[0001] The utility model relates to a breeding device, in particular to a raft-type breeding device for cuttlefish. Background Art

[0002] In recent years, with the progress of aquaculture technology, cuttlefish breeding has become an important part of the aquaculture field. In particular, significant breakthroughs have been made in the breeding technologies of Sepiella maindroni and Sepia pharaonis, making it possible to carry out industrialized artificial breeding and sea cage breeding of cuttlefish, and achieving good economic and social benefits. At present, industrialized cuttlefish breeding mainly relies on two methods: cement pond breeding and sea cage breeding. Due to their simple structure and easy management, these two methods have been widely used in cuttlefish breeding.

[0003] However, despite the many advantages of industrialized breeding methods, there are still some deficiencies. First, during the breeding process, cuttlefish need to be graded and bred at different specifications regularly, which involves frequent catching operations. Second, to ensure water quality cleanliness, it is necessary to regularly clean the residual bait and other pollutants at the bottom of the pond. During these operations, cuttlefish often have a strong stress response due to external interference. Especially when stimulated by the outside world, cuttlefish will eject a large amount of ink, and sometimes even die. This situation not only affects the health of cuttlefish but also may lead to a decrease in breeding survival rate.

[0004] In addition, traditional catching operations are usually more complex and prone to cause surface injuries to cuttlefish, increasing the risk of cuttlefish being injured. At the same time, when cleaning the bottom of the pond, cuttlefish are likely to ingest deteriorated residual bait, which not only affects their health but also increases the incidence of diseases, further reducing the breeding survival rate. Therefore, how to reduce the stress response of cuttlefish during the operation process, improve their breeding survival rate, simplify breeding operations, and reduce labor intensity has become an urgent problem to be solved in the current cuttlefish breeding technology. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a raft-type breeding device for cuttlefish, which can reduce the stress response of cuttlefish during the operation process, improve their breeding survival rate, simplify breeding operations, and reduce labor intensity.

The bottom net is connected to the raft-type grid, and the side net surrounds the periphery of the raft-type grid and cooperates with the bottom net to form a breeding area with an open upper end. A flow control plate is also connected to the central position of the bottom net. When the raft-type grid is placed in a breeding pool, the flow control plate is directly above the drain outlet of the breeding pool.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0021] Example 1: As shown in the figure, a raft-type squid farming device includes a raft-type grid 1, a bottom net 2, a side net 3, and a flow control plate 4. An inflation and deflation chamber 5 is formed inside the raft-type grid 1, and the raft-type grid 1 has a water inlet 6 and a water outlet 7 communicating with the inflation and deflation chamber 5. The bottom net 2 is connected to the raft-type grid 1, and the side net 3 surrounds the four sides of the raft-type grid 1 and cooperates with the bottom net 2 to form a breeding area with an open upper end. A flow control plate 4 is also connected to the center position of the bottom net 2. When the raft-type grid 1 is placed in a breeding pond, the flow control plate 4 is directly above the drain outlet of the breeding pond.

[0022] The floating and sinking operations of this raft-type squid farming device mainly rely on the principle of the inflation and deflation system. The specific implementation steps are as follows:

[0023] 1. Sinking stage:

[0024] Water injection: Water is injected into the inflation and deflation chamber 5 through the water inlet 6 on the raft-type grid 1.

[0025] Weight increase: After the inflation and deflation chamber 5 is filled with water, the weight increases, causing the entire raft-type grid 1 to sink.

[0026] Sinking to the appropriate position: According to the breeding requirements, adjust the water injection volume to make the raft-type grid 1 sink to the appropriate water depth position.

[0027] 2. Floating stage:

[0028] Air injection: Air is injected through the water inlet 6 on the raft-type grid 1.

[0029] Water discharge: After the air is injected, the water in the inflation and deflation chamber 5 will be discharged from the drain outlet.

[0030] Weight reduction: Since the water in the inflation and deflation chamber is discharged, the weight is reduced, causing the raft-type grid 1 to float.

[0031] Floating to the appropriate position: According to the fishing needs, adjust the amount of injected air to make the raft-type grid 1 float to the appropriate fishing position.

[0032] 3. Circular operation:

[0033] After the fishing is completed, water is injected again through the water inlet 6 to fill the inflation and deflation chamber 5 with water, and the raft-type grid 1 sinks to the appropriate depth again for normal breeding.

[0034] Example 2: As shown in the figure, different from Example 1, the raft-type grid 1 includes a circular frame 8, and a plurality of support pipes 9 are evenly distributed circumferentially inside the circular frame 8. Both ends of the support pipe 9 are fixedly connected to the inner side of the circular frame 8, and the inside of the circular frame 8 and the support pipe 9 is internally connected to form the inflation and deflation chamber 5.

[0035] In the above structure, the circular frame 8 serves as the external frame of the entire device, playing a role in support and fixation. The support pipes 9 are evenly distributed within the circular frame 8 and are in internal communication with the circular frame 8. These support pipes 9 can not only enhance the structural stability but also form a closed charging and discharging cavity 5 through their internal communication with the circular frame 8. When water or air is injected through the water inlet 6, the pressure within the charging and discharging cavity 5 will change, thereby driving the floating and sinking of the entire raft-type grid 1. This design is not only simple in structure, facilitating manufacturing and installation, but also can effectively control the charging and discharging process, ensuring the stable operation of the squid raft. At the same time, this structure can also effectively improve the charging and discharging efficiency, shorten the time of floating and sinking operations, and improve work efficiency.

[0036] In this embodiment, a partition 10 is provided within one of the support pipes 9, dividing the charging and discharging cavity 5 into two independent cavities 11. The two cavities 11 are respectively in communication with the water inlet 6 and the water outlet 7.

[0037] The above design not only improves the charging and discharging efficiency but also enhances the reliability and safety of the device. First of all, this design can effectively improve the charging and discharging efficiency. When it is necessary to sink, water can be injected into one of the cavities 11 through the water inlet 6, while air in the other cavity 11 can be discharged through the water outlet 7, thereby quickly increasing the weight of the device and making it sink rapidly. On the contrary, if it is necessary to float, air can be injected through the water inlet 6 to discharge the water in one of the cavities 11, and then the air in the other cavity 11 can be discharged through the water outlet 7, thereby quickly reducing the weight of the device and making it float quickly.

[0038] In addition, this design can also improve the safety of the device. Since the two cavities 11 are independent of each other, even if one of the cavities 11 fails, for example, the water inlet 6 or the water outlet 7 is blocked, the other cavity 11 can still work normally, ensuring that the device can float and sink normally. This avoids the risk that the entire device cannot float and sink due to the failure of a single cavity 11, which in turn affects the squid farming operation. Moreover, the two independent cavities 11 can be charged and discharged separately according to needs. For example, one cavity 11 can be filled with air first and then water can be injected to make the device float more stably in the water, effectively reducing the risk of squid injury.

[0039] In this embodiment, a first pipeline 12 is connected to the water inlet 6, and a first valve body 13 is installed on the first pipeline 12. A second pipeline 14 is connected to the water outlet 7, and a second valve body 15 is installed on the second pipeline 14.

[0040] In the above structure, the water inlet 6 and the water outlet 7 are respectively connected to the first pipe 12 and the second pipe 14, and the first valve body 13 and the second valve body 15 are installed. This design can effectively control the inflation and deflation operations, improve the controllability and safety of the device. Through the first valve body 13 and the second valve body 15, the water inflow and outflow can be adjusted, so as to flexibly control the floating and sinking speed and height of the device. For example, when quickly sinking, the first valve body 13 can be opened to accelerate the water injection speed; while when slowly floating, the first valve body 13 can be slightly opened to slow down the water injection speed to avoid causing harm to the squid due to too fast floating.

[0041] In this embodiment, a ballast steel pipe 16 is connected to the raft-type grid 1 through a quick-release mechanism 17. The quick-release mechanism 17 includes a hoop 18 and a locking bolt 19. The hoop 18 is sleeved outside the ballast steel pipe 16 and is fixedly connected to the raft-type grid 1 through the locking bolt 19.

[0042] The design of connecting the ballast steel pipe 16 to the raft-type grid 1 through the quick-release mechanism 17 can effectively optimize the performance of the squid raft-type breeding device. The quick-release mechanism 17 includes a hoop 18 and a locking bolt 19. The hoop 18 is sleeved outside the ballast steel pipe 16 and is fixedly connected to the raft-type grid 1 through the locking bolt 19. The structure is simple and the disassembly is convenient; the ballast steel pipe 16 is made of strong material and has reliable weight. Installing it outside the raft-type grid 1 will not occupy the internal space and will not affect the normal operation of the inflation and deflation system. By increasing or decreasing the number of ballast steel pipes 16, the total weight of the raft-type grid 1 can be flexibly adjusted, and then its floating and sinking depth can be controlled to meet the needs of different breeding stages. At the same time, the quick-release connection method makes the disassembly and assembly operation of the ballast steel pipe 16 very simple, greatly improving the work efficiency.

[0043] Embodiment 3: As shown in the figure, different from Embodiment 2, a plurality of circumferentially distributed vertical rods 20 are arranged to extend upward on the periphery of the raft-type grid 1, and the side netting 3 is connected between the plurality of vertical rods 20.

[0044] In the above structure, the arrangement of the vertical rods 20 provides reliable support and fixation for the side netting 3, enabling the side netting 3 to maintain a certain tension and shape, avoiding the netting from sagging or deforming, ensuring the integrity of the breeding area. At the same time, the plurality of vertical rods 20 are evenly distributed circumferentially, enabling the side netting 3 to obtain uniform support force, and the tension distribution of the netting is more uniform, thereby improving the stability of the entire grid structure.

[0045] The height of the vertical pole 20 can be adjusted according to requirements, so that the height of the side netting 3 also changes accordingly, thereby adjusting the volume of the aquaculture area to meet the requirements of different aquaculture densities. The high vertical pole 20 can also increase the depth of the water flow passing through the aquaculture area, optimize the water flow environment, and is beneficial to the growth of cuttlefish. The spacing between the vertical poles 20 can be selected according to the mesh size to make the tension of the netting moderate, avoiding being too tight or too loose.

[0046] In addition to fixing the side netting 3 by using the vertical pole 20, the side netting 3 can also be fixed and limited by hanging it in the aquaculture pool.

[0047] In this embodiment, the bottom netting 2 is a rigid plastic netting with a pore size of 10 - 30 mm, and the side netting 3 is a polyethylene netting with a pore size of 10 - 30 mm.

[0048] The rigid plastic netting is firm and durable, with excellent anti - aging performance. Even when placed underwater for long - term use, it will not quickly age, deform or break, and can well maintain the integrity and tension of the bottom netting 2, providing reliable bottom support for the aquaculture area. At the same time, this pore size range can effectively prevent impurities and large organisms from entering, and will not hinder water flow exchange, making it very suitable as the bottom basic netting.

[0049] The polyethylene netting has good flexibility and hydrophilicity, is not easy to entangle or scratch living things, and has excellent corrosion resistance, capable of coping with corrosive environments such as seawater. This pore size range can just block the escape of cuttlefish and meet the water flow exchange requirements during the growth process of cuttlefish, making it an ideal material for the side netting 3.

[0050] The two different - material netting cooperate with each other. The bottom is firm and durable, and the side is soft and friendly, jointly constructing a safe, reliable, water - flowing, and impurity - blocking good aquaculture environment. The rigid bottom net ensures the structural stability of the entire aquaculture area, while the soft side net maximally avoids harm to living things. The pore size ranges of both are also carefully designed to meet different functional requirements such as isolation and flow - through.

[0051] In this embodiment, the flow - control plate 4 is circular or square and is fixed to the raft - type grid 1 by welding or buckling.

[0052] The flow - control plate 4 is installed at the center of the bottom netting 2, facing the drainage outlet of the aquaculture pool, and can maximize its role in controlling water flow, forming a relatively static water area to avoid the cuttlefish being impacted and disturbed. The circular or square shape design of the flow - control plate 4 is reasonable, which can effectively block the drainage outlet. When the aquaculture pool is drained, it can prevent the water flow from directly impacting the netting, preventing the cuttlefish from being washed away or injured by the water flow. The circular flow - control plate 4 can better adapt to the circular drainage outlet and has a larger shielding range; while the square flow - control plate 4 is more convenient to manufacture and install.

[0053] The two fixing methods of welding and buckling can ensure the reliable connection between the flow control plate 4 and the raft grid 1. The welded connection is firm and reliable, which can effectively prevent the flow control plate 4 from falling off under the impact of water flow; while the buckling connection is convenient for disassembly, which is beneficial to the maintenance and replacement of the flow control plate 4. The two methods can be selected according to actual needs.

[0054] The above description is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
