Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and in particular to a detachable, liftable deep-sea aquaculture device. Background Technology

[0002] As people's living standards continue to improve, the demand for aquatic products is also increasing accordingly. However, the carrying capacity of rivers and lakes is limited, and traditional land-based aquaculture methods face the problem of insufficient water resources in some areas, which cannot meet the growing aquaculture demand.

[0003] To address the aforementioned issues, existing technology provides a type of marine aquaculture cage, which is installed on the ocean surface to effectively utilize marine resources, open up a wider aquaculture space, and improve aquaculture efficiency. However, in actual operation, operators have found that existing marine aquaculture cages lack effective restraint mechanisms, making them susceptible to structural damage from wind and waves under severe weather conditions. This reduces the lifespan of the cages and hinders normal aquaculture production. Therefore, effectively mitigating damage caused by strong winds and waves to the cages is an urgent problem to be solved. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this invention is to provide a detachable, liftable deep-water aquaculture device to avoid the impact of strong winds and waves on the net cages, thereby ensuring the long-term use of the aquaculture device.

[0005] Based on this, the present invention provides a detachable, liftable deep-water aquaculture device, comprising:

[0006] A frame, wherein the interior of the frame is hollow and has an assembly cavity;

[0007] An airbag is disposed within and connected to the frame, and the airbag is connected to an inflation pump via an air supply pipe;

[0008] The aquaculture cage is installed within the frame and located in the assembly cavity;

[0009] A fixed pulley is provided below the frame and the aquaculture net cage. A connecting rope is provided on the fixed pulley. One end of the connecting rope is connected to the frame, and the other end of the connecting rope is connected to the aquaculture net cage.

[0010] The fixed pulley is fixed to the continental shelf by a limiting member, and both the frame and the aquaculture cage are located below sea level.

[0011] In some embodiments of this application, the inner edge of the frame is provided with a limiting plate extending into the assembly cavity.

[0012] In some embodiments of this application, the limiting plate is provided in a plurality of blocks, and each limiting plate is arranged sequentially and evenly around the circumference of the aquaculture net cage.

[0013] In some embodiments of this application, the thickness of the limiting plate gradually decreases from top to bottom, and the cross-section of the limiting plate is triangular.

[0014] In some embodiments of this application, a plurality of fixed pulleys are provided, and the fixed pulleys are arranged sequentially around the circumference of the aquaculture net cage, and each fixed pulley is fitted with a connecting rope.

[0015] In some embodiments of this application, the connecting rope is a steel wire rope.

[0016] In some embodiments of this application, the number of the limiting members is the same as the number of the fixed pulleys and they correspond one-to-one with the fixed pulleys.

[0017] In some embodiments of this application, the limiting member is a suction anchor.

[0018] In some embodiments of this application, a clockwork spring is also included, which is disposed at the top of the frame and connected to the aquaculture cage.

[0019] The detachable, liftable deep-water aquaculture device provided in this invention has the following advantages compared to the prior art:

[0020] This invention provides a detachable, liftable deep-sea aquaculture device, comprising a frame, an air bladder, an aquaculture net cage, and a fixed pulley. The frame is hollow, forming an assembly cavity. The air bladder is located within and connected to the frame, and further, it is connected to an air pump via an air supply pipe. The aquaculture net cage is located within the frame and in the assembly cavity, with a buoyancy component at its bottom. The fixed pulley is located below the frame and the aquaculture net cage, and a connecting rope is fitted onto the pulley. One end of the connecting rope is connected to the frame, and the other end is connected to the aquaculture net cage. It should be further noted that the fixed pulley is also fixed to the continental shelf on the seabed by a limiting component. Both the frame and the aquaculture net cage sink into the ocean under the action of the connecting rope, meaning both the frame and the aquaculture net cage are below sea level. To enhance the limiting effect, in this embodiment of the invention, the connecting rope is preferably a steel wire rope, and the limiting component is preferably a suction anchor. Based on the above structure, during use, the gas inside the airbag is released, and connecting ropes are used to connect the frame to the aquaculture cage. The aquaculture cage is then placed inside the assembly chamber. After assembly, the cage is submerged in the ocean, and a limiting device is used to fix the fixed pulley. At this point, the entire aquaculture device is fixed below sea level. Since the airbag is connected to an air pump via an air supply pipe, the operator can inflate the airbag using the pump. As the gas fills the airbag, its buoyancy continuously increases. When the buoyancy of the airbag exceeds the buoyancy provided to the aquaculture cage by the buoyancy device, the airbag rises, pulling the frame upwards. It can be observed that, because the position of the fixed pulley remains unchanged, as the frame rises, the aquaculture cage is pulled downwards by the connecting ropes, eventually causing the aquaculture cage to sink to the deep sea area. Correspondingly, operators can release gas from the airbags through the air supply pipes. As the gas is released, the buoyancy of the airbags decreases, and the frame gradually sinks due to the reduced buoyancy. When the buoyancy of the airbags becomes less than the buoyancy provided to the aquaculture cage by the buoyancy components, the aquaculture cage begins to rise continuously. The frame sinks as the aquaculture cage rises, allowing it to rise above sea level to complete subsequent operations such as net retrieval or seeding. Thus, this application submerges the aquaculture cages in deep-sea areas below sea level, completely avoiding damage caused by strong winds and significantly reducing wave loads from large waves, thereby minimizing economic losses from cage damage. Furthermore, the frame is independent of the aquaculture cage, with the frame fitted over it, further enhancing vibration isolation and reducing the likelihood of cage damage.

[0025] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] It should be understood that the terms "before," "after," etc., are used in this invention to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this invention.

[0027] like Figures 1 to 3 As shown, this invention provides a detachable, liftable deep-sea aquaculture device, which includes a frame 1, an air bladder 2, an aquaculture net cage 3, and a fixed pulley 5. Specifically, the frame 1 is hollow and has an assembly cavity. The air bladder 2 is located inside and connected to the frame 1. Furthermore, the air bladder 2 is connected to an air pump via an air supply pipe. The aquaculture net cage 3 is located inside the frame 1 and within the assembly cavity, and a buoyancy component 4 is provided at the bottom of the aquaculture net cage 3. The fixed pulley 5 is located below the frame 1 and the aquaculture net cage 3, and a connecting rope 6 is fitted onto the fixed pulley 5. One end of the connecting rope 6 is connected to the frame 1, and the other end is connected to the aquaculture net cage 3. It should be further noted that the fixed pulley 5 of this application is also fixed to the continental shelf on the seabed by a limiting component 8. Both the frame 1 and the aquaculture net cage 3 sink into the ocean under the action of the connecting rope 6, that is, both the frame 1 and the aquaculture net cage 3 are located below the sea level. To enhance the limiting effect, in a specific embodiment of the present invention, the connecting rope 6 is preferably a steel wire rope, and the limiting member 8 is preferably a suction anchor.

[0028] Based on the above structure, during use, the gas inside the airbag 2 is released, and the connecting rope 6 connects the frame 1 to the aquaculture cage 3. The aquaculture cage 3 is then placed inside the assembly cavity. After assembly, the cage is submerged in the ocean. A limiting component 8 is used to fix the fixed pulley 5, thus securing the entire aquaculture device below sea level. Since the airbag 2 is connected to an air pump via an air supply pipe, the operator can inflate the airbag 2 using the pump. As the gas fills the airbag, its buoyancy increases. When the buoyancy of the airbag 2 exceeds the buoyancy provided to the aquaculture cage 3 by the buoyancy component 4, the airbag 2 rises, pulling the frame 1 upwards. It can be observed that because the position of the fixed pulley 5 remains constant, as the frame 1 rises, the aquaculture cage 3 is pulled downwards by the connecting rope 6, eventually sinking to the deep sea area. Correspondingly, operators can also release gas from the airbag 2 through the air supply pipe. As the gas is released, the buoyancy of the airbag 2 decreases, and the frame 1 gradually sinks due to the reduced buoyancy. When the buoyancy of the airbag 2 is less than the buoyancy provided by the buoyancy component 4 to the aquaculture cage 3, the aquaculture cage 3 begins to rise continuously. The frame 1 then sinks as the aquaculture cage 3 rises, allowing the aquaculture cage 3 to rise continuously and eventually reach above sea level to complete subsequent operations such as net retrieval or seedling introduction. Thus, by sinking the aquaculture cage 3 into the deep sea area below sea level, this application can completely avoid damage to the cage caused by strong winds, and also significantly reduce the damage to the cage structure caused by wave loads from large waves, thereby reducing economic losses caused by damage to the aquaculture cage 3. Furthermore, the frame 1 of this application is independent of the aquaculture cage 3; the frame 1 is fitted outside the aquaculture cage 3, which can further improve the vibration isolation effect and reduce the possibility of damage to the aquaculture cage 3.

[0029] Optionally, in some embodiments of this application, a limiting plate 7 extending into the assembly cavity is provided on the inner edge of the frame 1. Based on the above structure, the limiting plate 7 can guide and control the movement of the aquaculture cage 3 in the assembly cavity, preventing the aquaculture cage 3 from getting stuck between the frame 1.

[0030] Furthermore, in some embodiments of this application, the width of the limiting plate 7 increases sequentially from bottom to top, meaning the cross-section of the limiting plate 7 is triangular. Based on the above structure, the movable area of ​​the aquaculture cage 3 continuously decreases during the floating process, effectively ensuring the normal floating of the aquaculture cage 3 and preventing it from getting stuck with the frame 1 during the floating process.

[0031] Furthermore, in order to simultaneously enhance the limiting and guiding effects of the limiting plate 7, the limiting plate 7 of this application is provided with several pieces, and each limiting plate 7 is arranged evenly around the circumference of the aquaculture net cage 3.

[0032] It should be noted that, since the aquaculture cage 3 of this application has a cylindrical structure, the corresponding assembly cavity is also cylindrical, and the opening at the top of the frame 1 is set to be circular. Of course, the shape of the aquaculture cage 3 and the assembly cavity can be adjusted in various ways according to the actual aquaculture situation, which will not be elaborated here.

[0033] Furthermore, in order to enhance the fixing effect on the frame 1 and the aquaculture cage 3 and ensure that they are stably set below the sea level, in some embodiments of this application, a number of fixed pulleys 5 are provided, and each fixed pulley 5 is arranged in sequence around the circumference of the aquaculture cage 3. Correspondingly, each fixed pulley 5 is fitted with a connecting rope 6. One end of these connecting ropes 6 is connected to the frame 1, and the other end is connected to the aquaculture cage 3 again.

[0034] Furthermore, as the number of fixed pulleys 5 increases, the limiting members 8 can also be added accordingly. In this embodiment of the invention, the number of limiting members 8 is the same as that of fixed pulleys 5 and corresponds one-to-one with fixed pulleys 5, which can significantly enhance the fixing effect of fixed pulleys 5, thereby improving the fixing effect on frame 1 and aquaculture net cage 3.

[0035] In addition, in some embodiments of this application, the aquaculture device further includes a spring 9, which is located at the top of the frame 1 and connected to the aquaculture net cage 3. Based on the above structure, the spring 9 can guide the upward and downward movement of the aquaculture net cage 3, ensuring that it does not collide with the frame 1, reducing the probability of damage to the aquaculture net cage 3, and extending the service life of the aquaculture net cage 3.

[0036] In summary, this invention provides a separable, liftable deep-sea aquaculture device, comprising a frame 1, an airbag 2, an aquaculture net cage 3, and a fixed pulley 5. The frame 1 is hollow and forms an assembly cavity. The airbag 2 is located inside and connected to the frame 1, and is also connected to an air pump via an air supply pipe. The aquaculture net cage 3 is located inside the frame 1 and within the assembly cavity, and has a buoyancy component 4 at its bottom. The fixed pulley 5 is located below the frame 1 and the aquaculture net cage 3, and a connecting rope 6 is fitted onto the fixed pulley 5. One end of the connecting rope 6 is connected to the frame 1, and the other end is connected to the aquaculture net cage 3. Compared with the prior art, this application can submerge the aquaculture net cage 3 in deep-sea areas, thereby completely avoiding damage to the net cage caused by strong winds. It can also greatly reduce the damage to the net cage structure caused by wave loads from giant waves, thereby reducing the economic losses caused by damage to the aquaculture net cage 3. The frame 1 is independent of the aquaculture net cage 3 and is fitted outside the aquaculture net cage 3, which can further improve the vibration isolation effect and reduce the possibility of damage to the aquaculture net cage 3.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
