Description

A three-dimensional marine aquaculture cage structure Technical Field

[0001] This utility model relates to the field of new aquaculture technology, and in particular to a three-dimensional marine aquaculture cage structure. Background Technology

[0002] With the increasing global demand for marine resource development, deep-sea aquaculture has become an important development direction for the marine industry due to its enormous economic and ecological value. Existing technologies combine aquaculture cages with offshore wind turbine foundations, which can fully utilize the inherent structural strength and wave resistance of wind turbines, reduce the construction cost of additional anchoring facilities, and shorten the construction cycle of the cages. At the same time, this structural setup can also directly utilize wind power to supply power to the aquaculture cage equipment, making energy supply faster and more convenient.

[0003] However, since the cage system is usually fixed at the top of the pile near the water surface, when waves hit the cage, the force is concentrated and transmitted to the top area of ​​the pile through the rigid connection point, forming a local stress concentration, which aggravates the risk of fatigue damage and plastic deformation of the pile, and may even induce pile foundation fracture or overturning under extreme sea conditions.

[0004] Therefore, in the aquaculture model that combines aquaculture cages with offshore wind turbine foundations, how to improve the stress performance of the wind turbine foundations and thus enhance their structural safety is a technical problem that urgently needs to be solved in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the existing technology that, since the cage system is usually fixed at the top of the pile near the water surface, when waves impact the cage, the force is concentrated and transmitted to the top area of ​​the pile through the rigid connection point, forming local stress concentration, which aggravates the risk of fatigue damage and plastic deformation of the pile. The invention provides a three-dimensional marine aquaculture cage structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A marine three-dimensional aquaculture cage structure includes a cage body and a buoyancy box. The buoyancy box is located at the bottom of the cage body and is used to provide buoyancy so that the cage body floats on the water surface. The cage body is configured as a cylindrical structure and is divided into a first aquaculture zone and a second aquaculture zone along its diameter. The first aquaculture zone and the second aquaculture zone are detachably connected.

[0008] The middle part of the cage body is also provided with a limiting cavity, and the fixing pile passes through the limiting cavity. The diameter of the limiting cavity is larger than the diameter of the wind turbine pile body.

[0009] A force transmission plate is provided at the bottom of the first aquaculture area and the second aquaculture area corresponding to the area of ​​the limiting cavity. The cross-section of the force transmission plate is a semi-circular arc structure. The diameter of the force transmission plate matches the diameter of the limiting cavity. The force transmission plate extends to the seabed. A fixing airbag is also provided on one side of the end of the force transmission plate. The fixing airbag is used to fill the gap between the force transmission plate and the wind turbine pile body.

[0010] Preferably, the fixed airbag and the force transmission plate are detachably connected.

[0011] Preferably, a limiting plate is provided on the force transmission plate, and a gap is provided between the limiting plate and the inner surface of the force transmission plate, and the fixing airbag is snapped between the force transmission plate and the limiting plate.

[0012] Preferably, the limiting plate is made of flexible rubber material.

[0013] Preferably, the contact surface between the limiting plate and the fixing airbag is set as a rough surface.

[0014] Preferably, a baffle is provided at the end of the force transmission plate, the baffle being used to prevent the fixed airbag from extending beyond the end of the baffle when it is inflated.

[0015] Preferably, a haunch plate is provided at the connection between the force transmission plate and the cage body, and the haunch plate is used to enhance the structural strength of the connection between the two.

[0016] Preferably, the top of the cage body is above sea level.

[0017] Preferably, the top of the cage body is also provided with a walkway for operators to walk on.

[0018] Preferably, guardrails are provided on both sides of the walkway.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. The marine three-dimensional aquaculture cage structure of this utility model is provided with a force transmission plate extending downward from the bottom of the cage body along the limiting cavity to the seabed, and a fixing airbag filling the gap between the force transmission plate and the wind turbine pile body. In this way, the wave impact force on the cage body can be directly transmitted to the middle and lower part of the pile body, avoiding the stress concentration at the top of the pile body in the traditional top fixing mode, thereby reducing the risk of fatigue damage and plastic deformation of the pile body and improving the structural safety of the pile body;

[0021] 2. The marine three-dimensional aquaculture cage structure of this utility model includes a limiting plate on the force transmission plate, with a gap between the limiting plate and the inner surface of the force transmission plate. The fixing airbag is snapped between the force transmission plate and the limiting plate. This structural design improves the stability of the fixing airbag connected to the force transmission plate, preventing displacement of the fixing airbag due to wave surges during use, or its detachment from the bottom of the force transmission plate. This ensures that the impact force of the waves is effectively transmitted to the bottom side of the pile, further improving the structural safety of the pile. Simultaneously, in this embodiment, the limiting plate secures the fixing airbag to the force transmission plate. During the transfer of the first and second aquaculture areas, adjusting the expansion of the fixing airbag ensures consistent buoyancy on both sides of the first and second aquaculture areas, preventing structural damage due to overturning during transfer. This further enhances the practicality of this invention in actual use.

[0022] 3. In the marine three-dimensional aquaculture cage structure described in this utility model, a baffle is further provided at the end of the force transmission plate. The baffle is used to prevent the fixing airbag from extending beyond the end of the baffle when inflated. This structural design avoids contact between the fixing airbag and the seabed, thereby reducing the risk of damage to the fixing airbag during actual use. Attached Figure Description

[0032] Example 1: As shown in Figures 1 and 2, the present invention provides a marine three-dimensional aquaculture cage structure, comprising a cage body 1 and a buoyancy box 2. The buoyancy box 2 is located at the bottom of the cage body 1 and is used to provide buoyancy for the cage body 1 to float on the water surface. The cage body 1 is configured as a cylindrical structure and is divided into a first aquaculture zone 3 and a second aquaculture zone 4 along its diameter. The first aquaculture zone 3 and the second aquaculture zone 4 are detachably connected.

[0033] The middle part of the cage body 1 is also provided with a limiting cavity 5, and the fixing pile passes through the limiting cavity 5. The diameter of the limiting cavity 5 is larger than the diameter of the wind turbine pile body.

[0034] A force transmission plate 6 is provided at the bottom of the first aquaculture area 3 and the second aquaculture area 4, corresponding to the area of ​​the limiting cavity 5. The cross-section of the force transmission plate 6 is a semi-circular arc structure. The diameter of the force transmission plate 6 matches the diameter of the limiting cavity 5. The force transmission plate 6 extends to the seabed. A fixing airbag 7 is also provided on one side of the end of the force transmission plate 6. The fixing airbag 7 is used to fill the gap between the force transmission plate 6 and the wind turbine pile body.

[0035] The marine three-dimensional aquaculture cage structure described in this invention features a force transmission plate 6 extending downwards from the bottom of the cage body 1 along the limiting cavity 5 to the seabed. A fixing airbag 7 fills the gap between the force transmission plate 6 and the wind turbine pile. This allows the wave impact force on the cage body 1 to be directly transmitted to the lower middle part of the pile, avoiding stress concentration at the top of the pile as in the traditional top-fixed mode. This reduces the risk of fatigue damage and plastic deformation of the pile, and improves the structural safety of the pile.

[0036] Specifically, in this embodiment, the cage body 1 includes an isolation net and several supporting columns. The supporting columns are equidistantly arranged along the edges of the first aquaculture area 3 and the second aquaculture area 4. The buoyancy box 2 is located at the bottom of the supporting columns. The isolation net is arranged between the supporting columns, and the isolation net is provided with ribs to enhance its structural strength.

[0037] In this embodiment, a wing plate is provided at the junction of the first breeding area 3 and the second breeding area 4. The wing plate is provided with bolt holes, and the first breeding area 3 and the second breeding area 4 are connected together by the cooperation of bolts and nuts.

[0038] The fixed airbag 7 includes an air supply tube and an airbag body. Air can be injected into the airbag body through the air supply tube to make it inflate, or air can be expelled from the airbag body to make it deflate.

[0039] In a preferred embodiment, based on the above method, the fixing airbag 7 and the force transmission plate 6 are further designed to be separable. This structural arrangement facilitates the replacement of the fixing airbag 7 after damage, improving the practicality of this invention in actual use.

[0040] As a preferred embodiment, based on the above method, a limiting plate 8 is further provided on the force transmission plate 6, with a gap between the limiting plate 8 and the inner surface of the force transmission plate 6, and the fixing airbag 7 is snapped between the force transmission plate 6 and the limiting plate 8. This structural arrangement improves the stability of the fixing airbag 7 connected to the force transmission plate 6, preventing the fixing airbag 7 from shifting position or detaching from the bottom of the force transmission plate 6 due to wave surges during use. This ensures that the impact force of the waves can be effectively transmitted to the bottom side of the pile body, further improving the structural safety of the pile. Simultaneously, in this embodiment, the fixing airbag 7 is fixed to the force transmission plate 6 using the limiting plate 8. During the transfer of the first aquaculture area 3 and the second aquaculture area 4, by adjusting the expansion degree of the fixing airbag 7, the buoyancy on both sides of the first aquaculture area 3 and the second aquaculture area 4 can be kept consistent, avoiding structural damage to the first aquaculture area 3 and the second aquaculture area 4 due to overturning during transfer, thereby further improving the practicality of this invention in actual use.

[0041] As a preferred embodiment, based on the above method, the limiting plate 8 is further made of flexible rubber material. With this structural design, the limiting plate 8 can deform synchronously when the fixing airbag 7 inflates, avoiding excessive compression of the fixing airbag 7 by the limiting plate 8, which could cause it to break. At the same time, with this structural design, the fixing airbag 7 can also more fully inflate and fill the gap between the force transmission plate 6 and the wind turbine pile body, further ensuring that the impact force of the waves can be effectively transmitted to the bottom side area of ​​the pile body.

[0042] In a preferred embodiment, based on the above method, the contact surface between the limiting plate 8 and the fixing airbag 7 is further configured as a rough surface. This structural configuration improves the stability of the fixing airbag 7 connected to the force transmission plate 6.

[0043] As a preferred embodiment, based on the above method, a baffle 9 is further provided at the end of the force transmission plate 6. The baffle 9 is used to prevent the fixed airbag 7 from extending beyond the end of the baffle 9 when inflated. This structural arrangement avoids the fixed airbag 7 from contacting the seabed, thereby reducing the risk of the fixed airbag 7 rupturing during actual use.

[0044] As a preferred embodiment, based on the above method, a haunch plate 10 is further provided at the connection between the force transmission plate 6 and the cage body 1. The haunch plate 10 is used to enhance the structural strength of the connection between the two. This structural arrangement improves the overall stability of the present invention.

[0045] Example 2: As shown in Figures 1 and 2, the marine three-dimensional aquaculture cage structure of this utility model, based on the above method, further includes a top of the cage body 1 that is higher than sea level. This structural design reduces the risk of fish escaping from the top of the cage body 1, thereby further improving the practicality of this invention in actual use.

[0046] As a preferred embodiment, based on the above-described method, the top of the cage body 1 is further provided with a walkway 11 for operators to walk on. Guardrails 12 are provided on both sides of the walkway 11. This structural arrangement further improves the practicality of this invention in actual use.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
