Technical Field
[0001] The utility model relates to the technical field of aquaculture cages, in particular to a deep - sea and far - sea aquaculture cage. Background Art
[0002] The aquaculture scale of deep - sea and far - sea aquaculture cages is large and the value is high. Adequate preventive measures need to be taken to prevent losses to cultured fish caused by floating objects on the sea surface, large predatory organisms, and underwater theft.
[0003] The cages for deep - sea and far - sea aquaculture usually need to be provided with a double - layer aquaculture net. The inner net provides a safe and stable aquaculture water body for culturing fish. Usually, an outer protective net is arranged outside the inner net. Generally, the outer net is divided into an outer protective net on the water surface and an outer protective net underwater. The outer protective net on the water surface is used to prevent floating objects on the water surface. The outer protective net underwater is arranged in the cage area below the splash zone and is used to cope with the intrusion of large predatory marine organisms, the impact of underwater floating objects, and underwater theft. Traditional underwater outer nets usually use nylon, polyethylene or polypropylene materials and are provided with relatively large mesh sizes, generally more than 10 cm.
[0004] Traditional outer nets need to be regularly cleaned of attached substances. The long - term accumulation of attached marine organisms will hinder the water exchange in the cage, thereby affecting the health of cultured fish. At the same time, the long - term accumulation of attached marine organisms will increase the water resistance of the fishing net. In extreme cases, it will cause the damage of the netting. After the outer net is damaged, the netting fragments may contact the inner net under the action of the tidal current, thereby causing wear and even damage to the inner netting. In aquaculture practice, some cages adopt the method of setting a "disposable outer net", that is, when the attached marine organisms on the outer net reach a certain degree, the outer net is destructively removed from the cage. According to the actual situation of different waters, the frequency of this operation ranges from half a year to one year. The new outer netting is installed in place by means of underwater installation. Although this operation avoids the cleaning of the outer net, it increases the cost of the outer net. At the same time, the underwater net replacement is seriously affected by the sea conditions. Underwater operations are time - consuming and labor - intensive and are quite dangerous. Summary of the Utility Model

[0030] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below in combination with specific implementation modes and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0031] An embodiment of the present utility model provides a deep - sea and far - sea aquaculture cage. As Figure 1 and Figure 2 shown, Figure 1 is a schematic diagram of the overall structure of the outer protective net 2 of the aquaculture cage without the cross beam 13 in an embodiment. The deep - sea and far - sea aquaculture cage includes: a main body 1 of the aquaculture cage and an outer protective net 2. The outer protective net 2 is sleeved outside the main body 1 of the aquaculture cage. The main body 1 of the aquaculture cage includes an inner netting and columns 11. The inner netting and the columns 11 are fixedly connected. The outer protective net 2 is connected to the columns 11. The mesh of the outer protective net 2 is larger than that of the inner netting, and the mesh of the outer protective net 2 is arranged in a rectangular shape. It should be noted that the specific shape of the main body 1 of the aquaculture cage and the number of columns 11 are not limited here, nor is the structure and fixing method of the inner netting limited, as long as it can form an aquaculture area through the inner netting. A deep - sea aquaculture cage including four columns 11 is given in this embodiment. The outer protective net 2 is fixed on two adjacent columns 11. Through such a setting, the outer protective net 2 protects the aquaculture area formed by the inner netting. By setting the mesh of the outer protective net 2 to be larger than that of the inner netting, the outer protective net 2 can block the attachments and floating objects in the sea water from contacting the inner netting, prevent large predatory organisms from damaging the inner netting and affecting the aquaculture environment. At the same time, the outer protective net 2 with large meshes also avoids the accumulation of attachments during its long - term use, which affects the water exchange in the main body 1 of the aquaculture cage. Further, the mesh of the outer protective net 2 is arranged in a rectangular shape, which makes the size of the outer protective net 2 unified during the processing process, facilitating batch processing. At the same time, the rectangular mesh arrangement is also beneficial to the installation and forming of the outer protective net 2, saving installation time.
[0032] Combined with Figure 3, in a preferred scenario, the outer protective net 2 includes a transverse net chain 21 and a longitudinal net chain 22. Both ends of the transverse net chain 21 are connected to two adjacent upright columns 11, and the longitudinal net chain 22 is connected to the transverse net chain 21. It should be noted that the connection method between the transverse net chain 21 and the longitudinal net chain 22 is not restricted here. Optionally, they can be integrally formed during the processing and production process, or fixed by tying at the intersection position of the transverse net chain 21 and the longitudinal net chain 22, or other forms that can satisfy the connection and fixation of the transverse net chain 21 and the longitudinal net chain 22; nor is the relative arrangement method of the transverse net chain 21 and the longitudinal net chain 22 restricted. For example, all the transverse net chains 21 are arranged on the side close to the inner netting, or all the longitudinal net chains 22 are arranged on the side close to the inner netting, or the transverse net chain 21 and the longitudinal net chain 22 are arranged in an interspersed manner. In a preferred scenario, the transverse net chain 21 and the longitudinal net chain 22 are arranged in an interspersed manner, that is, among two adjacent intersection points of the transverse net chain 21 and the longitudinal net chain 22, the transverse net chain 21 at one intersection point is arranged at a position close to the inner netting, and the longitudinal net chain 22 at the other intersection point is arranged at a position close to the inner netting. Through such a setting, the integrity of the outer protective net 2 is better and the structure is more stable. In a preferred scenario, the spacing of the transverse net chain 21 is between 500 mm and 700 mm, and the spacing of the longitudinal net chain 22 is between 1000 mm and 1500 mm. Through such a setting, the outer protective net 2 can protect the inner netting, save materials, reduce costs, and setting the grid of the outer protective net 2 to be relatively large can also reduce the influence of attachments on the outer protective net 2.
[0033] Combined with Figure 1 and Figure 2 , in a preferred scenario, the aquaculture cage body 1 further includes a connecting column 12 provided at the bottom of the aquaculture cage body 1. The connecting column 12 is fixedly connected to two adjacent upright columns 11, and the bottom of the protective net is connected to the connecting column 12. Through such a setting, the installation of the longitudinal net chain 22 is more firm, the amplitude of movement with the seawater is smaller, the overall stability of the outer protective net 2 is improved, and the integrity of the aquaculture cage body 1 is further improved. The specific shape and size of the connecting column 12 are not restricted here, as long as it can stably install the outer protective net 2. Preferably, a similar structure can also be provided at the top of the adjacent upright columns 11 to improve the stability of the overall structure of the aquaculture cage body 1.
[0034] Combined with Figure 4 and Figure 5, in another embodiment of the present utility model, the aquaculture cage main body 1 further includes a cross beam 13, which is arranged parallel to the upper part of the connecting column 12. The top of the outer protective net 2 is connected to the cross beam 13, and the bottom of the outer protective net 2 is connected to the connecting column 12. Through such a setting, the installation of the outer protective net 2 is made more firm, and the ability of the outer protective net 2 to resist seawater impact is improved. At the same time, the cross beam 13 connects two adjacent columns 11, further improving the stability of the overall structure of the aquaculture cage main body 1.
[0035] Combined with Figures 3 to 9 , in a preferred case, the columns 11, the connecting columns 12 and the cross beam 13 are provided with connecting parts 14, and through holes are formed on the connecting parts 14. The outer protective net 2 and the through holes are connected through snap rings 23. Through such a setting, the installation process of the outer protective net 2 is simplified. Through the cooperation connection of the through holes on the connecting parts 14 and the snap rings 23, the outer protective net 2 is firmly installed. It should be noted that the specific shape of the connecting part 14 is not limited here, as long as it can meet the requirement of setting through holes on the connecting part 14 and can withstand the tensile force generated during the installation and operation of the outer protective net 2. Nor is the connection method of the connecting part 14 to the columns 11, the connecting columns 12 and the cross beam 13 limited, which can be welding or clamping, or other forms that can meet the fixation of the outer protective net 2, such as tying the connecting part 14 to the columns 11, the connecting columns 12 and the cross beam 13 with steel wires.
[0036] In an optional case, the outer protective net 2 can be made of steel wire ropes, ropes or chains. When using a steel wire rope or rope structure, the transverse mesh chains 21 and the longitudinal mesh chains 22 can be connected in a tied or woven integrated form. Combined with Figure 7 and Figure 8 , in a preferred case, the transverse mesh chains 21 and the longitudinal mesh chains 22 of the outer protective net 2 adopt a chain structure. Through such a setting, the chain structure has advantages such as high tensile strength, strong wear resistance and good shear resistance, and can well resist the impact of underwater floating objects and water flow, making the service life of the outer protective net 2 with a chain structure longer, and it can be realized that it does not need to be replaced during the entire practical period of the deep-sea aquaculture cage, saving the operation cost and improving the continuity during the operation process.
[0037] As Figure 7 shown, in an optional case, chain eyelets 24 are provided at the intersection of the transverse mesh chains 21 and the longitudinal mesh chains 22, and the transverse mesh chains 21 and the longitudinal mesh chains 22 are connected through the chain eyelets 24. The integrity of the outer protective net 2 connected through the chain eyelets 24 is better and it is more stable during the operation of the deep-sea aquaculture cage. As Figure 8As shown, in another alternative scenario, a connecting buckle 25 is provided at the intersection of the transverse mesh chain 21 and the longitudinal mesh chain 22, and the transverse mesh chain 21 and the longitudinal mesh chain 22 are connected through the connecting buckle 25. With such a setting, the transverse mesh chain 21 and the longitudinal mesh chain 22 can be installed step by step, facilitating the installation of the outer protective net 2. By connecting each intersection of the transverse mesh chain 21 and the longitudinal mesh chain 22, the levelness of the transverse mesh chain 21 is improved, and the overall appearance quality of the outer protective net 2 is enhanced. At the same time, during operation, the force on the outer protective net 2 is more uniform. It should be noted that the specific structures of the chain eyelet 24 and the connecting buckle 25 are not limited here, as long as they can meet the connection of the transverse mesh chain 21 and the longitudinal mesh chain 22.
[0038] In a preferred scenario, the distance between the outer protective net 2 and the inner mesh is at least 2 meters. With such a setting, it is avoided that after the outer protective net 2 is impacted, it contacts the inner mesh and causes damage, or in an extreme case, when the outer mesh is damaged, the transverse mesh chain 21 and the longitudinal mesh chain 22 will not contact the inner mesh either, further ensuring that the inner mesh is not interfered with or damaged.
[0039] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples that fall within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
