Description

Technical Field

[0001] This application relates to the field of marine ranching technology, and more specifically, to an automatically lifting deep-sea cage for marine ranching. Background Technology

[0002] As my country's marine fisheries accelerate their transformation and upgrading, deep-sea aquaculture has become a core approach to addressing issues such as near-shore aquaculture space saturation and excessive environmental carrying capacity. It is of great strategic significance for ensuring a stable supply of the "blue granary." As the core equipment for deep-sea aquaculture, the performance of deep-sea cages directly determines the safety of aquaculture, the survival rate of catches, and economic benefits.

[0003] In related technologies, to improve resistance to wind and waves, for example, patent CN222322511U provides an easy-to-clean, wave-resistant deep-sea marine ranching cage. This easy-to-clean, wave-resistant deep-sea marine ranching cage achieves efficient cleaning and management: It adopts a liftable design, allowing operators to easily raise the aquaculture cage to the surface for cleaning and management without the need for cumbersome diving operations. This improves cleaning and management efficiency and reduces labor intensity; Stability and safety: The robust and stable external fixed frame structure is firmly fixed to the seabed through an anchoring mechanism, ensuring the entire marine ranch maintains a stable position even in harsh marine environments, improving the safety of the marine ranch; Precise control and adjustment: The cage positioning mechanism uses a pull rope method, with a drive motor precisely controlling the lifting and lowering of the cage, ensuring operational accuracy and stability. This design can cope with different marine environments and operational needs, exhibiting excellent flexibility and adaptability; Energy and resource conservation: The electric drive system provides stable power output while also offering energy-saving advantages. Furthermore, the liftable design reduces labor costs and the resource investment required for diving operations. Overall, this easily cleanable and wave-resistant deep-sea marine ranching cage design not only improves aquaculture efficiency and management levels but also achieves resource conservation and environmental protection while ensuring safety, representing an innovation and advancement in the marine aquaculture field. While the existing technical solutions mentioned above have solved the problem of weak risk resistance of traditional cages, they lack a guiding and positioning mechanism. As a result, the cages are prone to deviation and swaying during the lifting and lowering process. Especially under strong water flow or wind and wave disturbances, their posture stability is poor, which increases the risk of stress concentration in the cage structure and can easily lead to component damage with long-term use.

[0004] In view of this, we propose an automatically lifting deep-sea cage for marine ranching. Utility Model Content

[0005] The purpose of this application is to provide an automatic lifting deep-sea cage for marine ranching, which can effectively solve the problems of deviation and swaying that easily occur during the lifting process in the prior art.

[0006] This application provides an automatic lifting deep-sea cage for marine ranching, including a buoyancy ring, with a cage disposed in the middle of the buoyancy ring, and multiple mounting seats fixedly connected to the buoyancy ring, with through holes opened on the surface of the mounting seats; Multiple side blocks are fixedly connected to the top side of the cage. A device box is fixedly inserted through one side of each side block. An inflation device is installed inside the device box. A buoyancy airbag column is connected to the bottom of the device box. A lifting guide mechanism is provided between the side block and the mounting base.

[0007] As an optional solution to the technical solution of this application, the number of the multiple side blocks is the same as the number of multiple mounting bases, their positions are respectively corresponding, and they are all distributed in a ring array, and the position of the device box corresponds to the position of the through hole.

[0008] As an optional solution to the technical solution of this application, the air supply end of the inflation device is connected to the inner cavity of the buoyancy airbag column, and the bottom end of the buoyancy airbag column passes through the inner cavity of the through hole and is fixedly connected to a counterweight.

[0009] As an optional solution to the technical solution in this application, the buoyancy airbag column is T-shaped, and a pressure sensor is installed on one side of the top of the buoyancy airbag column.

[0010] As an optional solution to the technical solution in this application, the lifting guide mechanism includes a fixing block fixed to the outer wall of the mounting base, the fixing block having a guide hole, and a guide rod fixedly connected to the outer wall of the side block.

[0011] As an optional solution to the technical solution of this application, the guide rod is designed in an L-shape, with one end of the guide rod sliding through the inner cavity of the guide hole and extending to the bottom of the fixing block.

[0012] As an optional solution to the technical solution in this application, the inner wall of the buoyancy airbag column has a fluororubber pressure-resistant layer and an aramid fiber woven mesh, and the outer wall of the buoyancy airbag column is coated with an anti-bioadhesion coating.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This application, by setting a lifting guide mechanism between the side blocks and the mounting base, and in conjunction with the design of multiple side blocks and mounting bases arranged in a circular array, utilizes the sliding engagement of the L-shaped guide rod and the guide hole on the fixed block to accurately guide and position the lifting process of the cage. This significantly solves the problems of easy deviation and swaying of the cage during lifting in the prior art. Especially under conditions of strong water flow or wind and wave disturbance, it can effectively improve the attitude stability of the cage, reduce the risk of structural stress concentration, and extend the service life of components.

[0014] The buoyancy airbag column of this application adopts a T-shaped design and is equipped with a counterweight at the bottom. Combined with the buoyancy adjustment function of the inflation equipment, it can not only ensure the effectiveness of buoyancy adjustment, but also further help maintain the balance of the cage during lifting and mooring. The fluororubber pressure-resistant layer and aramid fiber woven mesh on its inner wall greatly improve the deep-sea high pressure resistance of the buoyancy airbag column, while the anti-biofouling coating sprayed on the outer side can reduce the attachment of marine organisms, reduce maintenance costs, and improve the reliability of equipment operation.

[0015] This application utilizes a pressure sensor installed at the top of the buoyancy airbag column to detect the pressure data of the water layer in real time, providing data support for the precise inflation of the inflation equipment, enabling the net cage to be stably moored in the target water layer, adapting to the habitat needs of different aquaculture species, comprehensively improving the safety, flexibility and economy of deep-sea aquaculture, and better adapting to the complex and ever-changing deep-sea aquaculture environment, with significant practical value and promotion prospects.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-4This application discloses an automatic lifting deep-sea cage for marine ranching, including a buoyancy ring 1, which serves as the basic load-bearing and buoyancy support component of the cage system, providing initial buoyancy to maintain the overall structure floating on the sea surface or a designated water layer. A cage 2 is provided in the middle of the buoyancy ring 1 to accommodate aquaculture organisms and provide habitat and growth space. Multiple mounting seats 3 are fixedly connected to the buoyancy ring 1, serving as the mounting base for the fixed block 91 in the lifting guide mechanism 9. At the same time, through holes 4 provide a through channel for the buoyancy airbag column 8. Through holes 4 are opened on the surface of the mounting seats 3. Multiple side blocks 5 are fixedly connected to the top side of the net cage 2, used to connect the device box 6 and the guide rod 93, realizing the mechanical linkage between the net cage 2, the inflation device 7, and the lifting guide mechanism 9. The number of side blocks 5 is the same as the number of mounting seats 3, and their positions correspond to each other and are all distributed in a ring array. The device box 6 corresponds to the position of the through hole 4. One side of the side block 5 is fixedly penetrated by the device box 6, serving as the mounting cavity for the inflation device 7. The inflation device 7 is installed inside the device box 6, and its air supply end is connected to the inner cavity of the buoyancy airbag column 8. According to the detection data of the pressure sensor 11, the buoyancy airbag column 8 is inflated or deflated to adjust the buoyancy of the buoyancy airbag column 8. The bottom end of the device box 6 is connected to the buoyancy airbag column 8. The inner wall of the buoyancy airbag column 8 has a fluororubber pressure-resistant layer 12 and an aramid fiber woven mesh 13. Utilizing the high pressure resistance and corrosion resistance of fluororubber, the buoyancy airbag column 8 is enhanced to withstand the high pressure environment of the deep sea. The fluororubber pressure-resistant layer 12 forms the inner reinforcing structure of the buoyancy airbag column 8. Utilizing the high strength, high modulus, and tear resistance of aramid fiber, the structural strength of the buoyancy airbag column 8 is improved. The outer wall of the buoyancy airbag column 8 is sprayed with an anti-biofouling coating. Through low surface energy and bio-inhibiting components, it prevents marine organisms from attaching. A lifting guide mechanism 9 is set between the side block 5 and the mounting base 3. Through mechanical cooperation, it guides and positions the lifting process of the net cage 2, solving the problem of easy deviation and swaying of the net cage during lifting in the prior art.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The air supply end of the inflation device 7 is connected to the inner cavity of the buoyancy airbag column 8. The bottom end of the buoyancy airbag column 8 passes through the inner cavity of the through hole 4 and is fixedly connected to a counterweight 10 to provide downward gravity and prevent the buoyancy airbag column 8 from floating on the water surface when it is not inflated. The buoyancy airbag column 8 has a T-shaped design. A pressure sensor 11 is installed on one side of the top of the buoyancy airbag column 8 to detect the pressure data of the water layer in real time and transmit the data to the control unit of the inflation device 7.

[0021] Reference Figure 1 and Figure 2The lifting guide mechanism 9 includes a fixing block 91 fixed to the outer wall of the mounting base 3. The fixing block 91 has a guide hole 92. A guide rod 93 is fixedly connected to the outer wall of the side block 5. The guide rod 93 has an L-shaped design. One end of the guide rod 93 slides through the inner cavity of the guide hole 92 and extends to the bottom of the fixing block 91.

[0022] In summary, when the automatic lifting deep-sea cage for marine ranching disclosed in this application is in use, the buoyancy ring 1 first provides initial buoyancy to maintain the overall structural foundation's floating state. The pressure sensor 11 installed on the top of the buoyancy airbag column 8 detects the pressure data of the water layer in real time and transmits it to the control unit of the inflation device 7. The inflation device 7 inflates or deflates the inner cavity of the buoyancy airbag column 8 according to the data to adjust the buoyancy. The counterweight block 10 fixed at the bottom of the buoyancy airbag column 8 forms a balance with the buoyancy, driving the connected device box 6 and side block 5 to move, thereby driving the net fixed to the side block 5. The cage 2 is raised and lowered. During the raising and lowering process, the L-shaped guide rod 93 on the side block 5 slides along the guide hole 92 of the fixing block 91 on the outer side wall of the mounting base 3. With the corresponding distribution of the annular array of the side block 5 and the mounting base 3, and the limiting effect of the buoyancy airbag column 8 penetrating the through hole 4 of the mounting base 3, the cage 2 is accurately guided and positioned. At the same time, the fluororubber pressure-resistant layer 12 and the aramid fiber woven mesh 13 on the inner side wall of the buoyancy airbag column 8 ensure its deep-sea high pressure resistance, and the outer anti-biofouling coating reduces the attachment of marine organisms. Finally, the cage 2 is stably moored in the target water layer, adapting to the habitat needs of different aquaculture species.
