Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, and in particular to an anti-attachment net cage. Background Technology

[0002] In the past, the use of net cages has focused more on corrosion resistance, because they need to be immersed in seawater for a long time. Seawater is highly corrosive and can easily damage the net cages. No one has considered the problems caused by the attachment of marine fouling organisms.

[0003] Marine aquaculture cages are woven net cages used for cultivating marine organisms such as shellfish and fish. Traditional marine aquaculture cages, due to long-term immersion in seawater, are easily covered by marine fouling organisms such as algae, barnacles, and shellfish, causing the mesh to become clogged, hindering water exchange, and resulting in insufficient natural food and dissolved oxygen in the cage, which affects the growth of the cultured organisms. In addition, the attached organisms on the cage greatly increase its weight, and with the surging of the seawater, they exert a drag force on the floats, making the cage very easy to sink.

[0004] In existing technologies, the treatment of marine fouling organisms generally involves frequent cleaning or replacement of net cages. Mechanical methods such as rolling with wheels and beating are used to clean the net cages, which not only reduces the service life of the net cages but also requires a large amount of manpower and material resources, increasing the cost of marine aquaculture and causing unexpected deaths of farmed organisms.

[0005] The large number of fishing nets covered with marine debris at the docks also cause air pollution, seriously affecting the environment around the docks and the image of the city.

[0006] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an anti-fouling net cage, which aims to solve the problem that existing marine aquaculture net cages are easily attached by marine fouling organisms such as algae, barnacles, and shellfish due to long-term immersion in seawater, resulting in clogged mesh, hindering water exchange, insufficient natural food and dissolved oxygen in the net cage, and affecting the growth of aquaculture organisms.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An anti-adhesion cage is made of multiple ropes woven together, and the surface of the cage is coated with an anti-adhesion coating.

[0010] Furthermore, the anti-adhesion coating is made of special anti-adhesion agents, resins, etc., and has a thickness of 0.01mm-5mm. The mesh size of the cage is 0.5cm-10cm.

[0011] Furthermore, it also includes a square basket, the surface of which is coated with an anti-adhesion coating, and the net cage is fixed to the opening of the square basket by rope.

[0012] Furthermore, multiple support components are spaced apart inside the cage.

[0013] Furthermore, the surface of the support member is coated with an anti-adhesion coating.

[0014] Furthermore, the support components are square rods, which are fixed to the cage by welding and rope wrapping.

[0015] Furthermore, the support component is a disc with multiple through holes and multiple fixing holes at the edge of the disc. The support is connected to the net cage by winding a rope through the fixing holes.

[0016] The technical solution adopted in this utility model has the following beneficial effects:

[0017] In this application, an anti-fouling coating is applied to the outer surface of the net cage. The thickness of the anti-fouling coating is 0.01mm-5mm, and the anti-fouling coating is made of special anti-fouling agents, resins, etc. This coating can prevent marine fouling organisms such as algae, barnacles, and shellfish from attaching, avoiding clogging of the mesh, allowing the cultured organisms to grow better, and eliminating the need for regular replacement and cleaning, thus reducing damage to the net cage.

[0023] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In this embodiment, please refer to Figure 1and Figure 2 An anti-fouling net cage 1 is made of multiple ropes 3 woven together and coated with an anti-fouling coating 2 on its surface. This coating prevents marine fouling organisms from attaching to the net cage 1. After the net cage 1 is free of attachments, the mesh of the net cage 1 is transparent, which reduces the obstruction to water exchange. With sufficient water exchange, natural food and dissolved oxygen, the yield will increase compared to traditional aquaculture methods. The net cage 1 is also cleaned and replaced less often, which will increase the survival rate of the aquaculture.

[0025] The antifouling coating 2 has a thickness of 0.01mm-3mm. The thickness of the coating depends mainly on the coating method. Generally, a thin coating of 0.5mm is sufficient to achieve antifouling. The antifouling coating 2 uses a biomimetic, non-toxic, and environmentally friendly antifouling agent with announcement number CN103740163B. In the original design, only the antifouling performance of the ship bottom and offshore facilities was considered, without considering the antifouling performance in the marine aquaculture field. The antifouling agent is made of special antifouling agents, resins, etc. With improvements in the manufacturing process, the coating can prevent the attachment of marine fouling organisms such as algae, barnacles, and shellfish to the net cage, avoid clogging the mesh, allow the cultured organisms to grow healthily, and eliminate the need for regular replacement and cleaning, thus reducing damage to the net cage 1.

[0026] In this embodiment, the mesh size of the net cage 1 can be adjusted according to the marine organisms to be cultured and the culture period. For example, in the culture of marine organisms in the seedling stage of shellfish, the mesh size of the net cage 1 is generally 0.5cm. As the organisms grow, the mesh size is gradually replaced with a net cage with a mesh size of 5cm-10cm.

[0027] In this embodiment, as Figure 1 and Figure 3 As shown, multiple support members 4 are spaced apart inside the net cage 1. The shape and number of support members 4 can be adjusted according to the needs of use. When the support member 4 is a square rod, the square rod is in a closed loop shape and is fixed inside the net cage 1 by the rope 3. It can be laid flat on the water surface or the ground to realize the use of the bottom cage.

[0028] When the support 4 is a disc, the net cage 1 forms a multi-layered vertical spatial structure. Multiple through holes 5 are opened on the disc to ensure the water permeability of each layer, and multiple fixing holes 6 are opened at the edge of the disc. The rope 3 can be wrapped around and passed through the fixing holes 6 to be fixedly connected to the net cage 1 to form a breeding cage. In the use of this cage structure, the net cage 1 is generally made of rope 3 crisscrossed and woven into a sheet-like structure. The two sides of the sheet are surrounded around multiple discs to form a cylindrical structure with intervals between each layer. Before it is completely closed, there will be gaps in the whole to facilitate the placement of the breeding materials on the discs, and then the cage is closed by wrapping the rope.

[0029] In addition, in the use of this cage structure, one end of the net cage 1 is directly wrapped around the disc and sealed, while the other end is tied with ropes and then suspended and immersed in seawater.

[0030] In this embodiment, a square basket 7 is also used in marine aquaculture. The surface of the square basket 7 is also coated with an anti-adhesion coating 2. The net cage 1 is fixed to the opening of the square basket 7 by rope 3. That is, the net cage 1 covers the opening of the square basket 7, forming an aquaculture space. An opening is made in the net cage 1 to facilitate the placement of the cultured organisms. After the organisms are placed in, the opening of the net cage 1 can be tied with rope and then suspended and immersed in seawater, ultimately forming a square aquaculture cage. Specifically, as shown... Figure 4 As shown, using a square aquaculture cage coated with the anti-fouling coating 2 can effectively prevent the attachment of marine fouling organisms, improve the circulation efficiency of seawater, and thus increase the quality of aquaculture products.

[0031] In this embodiment, the support member 4 can also be configured as two rings, which are connected by multiple rods to form a cylindrical shape. The net cage 1 is then placed over the support member 4 to form a single-layer breeding cage.

[0032] In summary, the combination of the net cage 1 and the support component 4 of this utility model can form a structure required for various marine organism aquaculture, and can avoid the attachment of marine fouling organisms, thereby improving the quality of aquaculture. Furthermore, in this embodiment, taking scallops as an example, a scallop aquaculture experiment was conducted using a net cage 1 coated with an anti-fouling coating 2. Verification showed that because there are no marine fouling organisms attached to the net cage 1, the mesh is transparent, water exchange is sufficient, and natural food and dissolved oxygen are abundant, resulting in increased production compared to traditional aquaculture methods. On average, each cage produces more than 0.5 kg of scallop adductor muscles. The use of this net cage 1 can significantly reduce the heavy metal content, by an average of about 50% compared to scallops raised using traditional methods. Moreover, the farmed scallops are uniform in size and have plump adductor muscles: an average of 80 adductor muscles per kg, reaching the highest price standard.
