[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

Furthermore, terms such as "first" and "second" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0029] Netting hanger tests are used to study the fouling and biological attachment of netting made of different materials in freshwater or marine environments. This allows for comparison of the antifouling performance of netting made of different materials, in order to select suitable netting for aquaculture.

[0030] In related technologies, the hanging net test usually involves suspending the net on a fixed or floating facility at sea. The net only comes into contact with the sea or fresh water, which cannot truly simulate the actual aquaculture scenario. As a result, the test results are often biased. At the same time, since the net is suspended, it is prone to swaying underwater, which affects the attachment of fouling organisms and also affects the test results, thus affecting the selection of netting.

[0031] Therefore, such as Figures 1-4 As shown, this disclosure provides a fouling biofouling test cage, including a cage body 1 and a test hanging plate 2. The cage body 1 is used to place in water and to raise aquatic organisms. The cage body 1 is provided with an installation port 13. The test hanging plate 2 is provided with a first connector 21. The installation port 13 is provided with a second connector 14. The first connector 21 can be connected or separated from the second connector 14 so that the test hanging plate 2 is detachably connected to the installation port 13. The test hanging plate 2 is placed in water.

[0032] The test hanging piece 2 can be installed into the installation port 13 through the cooperation of the first connector 21 and the second connector 14. The test hanging piece 2 can close the installation port 13, so that the test hanging piece 2 is part of the net cage body 1 and is used to enclose the aquatic organisms being cultured.

[0033] It is understandable that the test hanger 2 can be disassembled and replaced because the first connector 21 and the second connector 14 can be connected and separated.

[0034] In the above technical solution, the installation port 13 on the net cage body 1 allows the test hanging plate 2 to be integrated into the net cage body 1. This enables the test hanging plate 2 to be used in actual aquaculture production processes, fully simulating the adhesion of fouling organisms to the test hanging plate 2 throughout the entire aquaculture process. This improves the accuracy of the hanging plate test and provides better screening of netting compared to existing hanging plate test methods. The first connector 21 and the second connector 14 facilitate the installation of the test hanging plate 2, enhancing connection strength. The test hanging plate 2 can also be disassembled for easy observation of fouling organism adhesion. Furthermore, it can be replaced according to the installation time to test different test hanging plates.

[0035] Optionally, in one embodiment of this disclosure, the first connector 21 extends circumferentially along the test hanger 2, and the second connector 14 extends circumferentially along the mounting opening 13, so that there is no gap after the test hanger 2 is connected to the mounting opening 13.

[0036] In this design, there is only one first connector 21 and one second connector 14. The first connector 21 is located at the circumferential edge of the test hanging piece 2, and the second connector 14 is located at the circumferential edge of the mounting opening 13. Thus, after the first connector 21 and the second connector 14 are connected, the circumferential edge of the test hanging piece 2 is connected to the circumferential edge of the mounting opening 13. This arrangement ensures that the circumferential edges of the test hanging piece 2 and the circumferential edges of the mounting opening 13 are completely connected, without any gaps or omissions, thus guaranteeing the enclosure effect on the aquatic organisms being cultured.

[0037] Optionally, in another embodiment of this disclosure, there may be multiple first connectors 21 and second connectors 14. Multiple first connectors 21 are spaced apart circumferentially along the test hanger 2, and multiple second connectors 14 are spaced apart circumferentially along the mounting opening 13. The first connectors 21 and second connectors 14 correspond one-to-one. Thus, the connection between the test hanger 2 and the mounting opening 13 is achieved through the cooperation of multiple first connectors 21 and second connectors 14.

[0038] Alternatively, in one embodiment of this disclosure, the first connector 21 and the second connector 14 are configured as zippers that can cooperate with each other.

[0039] The first connecting member 21 and the second connecting member 14 can cooperate with each other. That is, one of the first connecting member 21 or the second connecting member 14 is provided with a locking element to lock the first connecting member 21 and the second connecting member 14. This arrangement makes it easier to connect or separate the first connecting member 21 and the second connecting member 14, and the operation is quick. It should be noted that there is only one first connecting member 21 and one second connecting member 14, and they are a ring-shaped zipper structure.

[0040] Alternatively, in another embodiment of this disclosure, both the first connector 21 and the second connector 14 are constructed as binding ropes, and the first connector 21 and the second connector 14 are bound together and fixed. This arrangement also allows for very convenient connection and fixation of the first connector 21 and the second connector 14.

[0041] In some examples, there are multiple first connectors 21 and multiple second connectors 14. That is, multiple binding ropes are set on the test hanging plate 2, which are spaced apart along the circumferential edge of the test hanging plate 2, and multiple binding ropes are set on the mounting port 13, which are spaced apart along the circumferential edge of the mounting port 13. In this way, the binding ropes on the test hanging plate 2 and the binding ropes on the mounting port 13 can be tied and fixed respectively, which is convenient and quick to operate.

[0042] Optionally, in one embodiment of this disclosure, a first reinforcing member 22 is provided on the test hanger 2, extending circumferentially along the test hanger 2, and a first connecting member 21 is connected to the first reinforcing member 22. A second reinforcing member 15 is provided on the mounting opening 13, extending circumferentially along the mounting opening 13, and a second connecting member 14 is connected to the second reinforcing member 15. The first reinforcing member 22 increases the strength of the circumferential edge of the test hanger 2, and the second reinforcing member 15 increases the strength of the circumferential edge of the mounting opening 13, thereby improving the structural strength of the connection between the test hanger 2 and the mounting opening 13 and preventing detachment.

[0043] It is understandable that both the first reinforcing member 22 and the second reinforcing member 15 are annular structures. The first reinforcing member 22 is located at the circumferential edge of the test hanger 2, and the second reinforcing member 15 is located at the circumferential edge of the mounting port 13.

[0044] The first connector 21 can be sewn to the first reinforcing member 22 by a stitch, and the first reinforcing member 22 provides support for the first connector 21. The second connector 14 can be sewn to the second reinforcing member 15 by a stitch, and the second reinforcing member 15 provides support for the second connector 14.

[0045] Optionally, in one embodiment of this disclosure, both the first reinforcing member 22 and the second reinforcing member 15 are constructed as steel ropes, which are sewn onto the test hanging plate 2 and the mounting port 13, respectively. The steel ropes are polyethylene ropes with a diameter of 4 mm. This arrangement facilitates connection with the test hanging plate 2 and the mounting port 13, while improving strength and reducing cost.

[0046] Optionally, in one embodiment of this disclosure, there are multiple test hanging pieces 2 and multiple mounting ports 13, with each test hanging piece 2 corresponding to one mounting port 13. The multiple test hanging pieces 2 are spaced apart along the horizontal and / or vertical directions. This arrangement allows for the simultaneous testing of multiple different test hanging pieces 2 at different water depths, enriching the test results and enabling better screening of the netting.

[0047] In some examples, the test hangers 2 can be set at intervals along the horizontal direction or along the vertical direction as needed. Multiple hangers can also be set at the same time and distributed in an array, that is, they can be set at intervals along the horizontal direction and along the vertical direction at the same time.

[0048] Optionally, in one embodiment of this disclosure, the spacing between two adjacent test hangers 2 is 2m-5m. This arrangement avoids mutual interference between multiple test hangers 2, enabling better screening of the mesh.

[0049] Optionally, in one embodiment of this disclosure, the test hanging plate 2 includes a mesh sheet with mesh openings 23. Each test hanging plate 2 has a different mesh sheet material and / or different mesh openings 23 apertures. Since different mesh openings 23 apertures can affect the adhesion of fouling organisms, this arrangement can simulate the actual usage of different mesh sheets, thereby better screening the mesh sheet material and the mesh openings 23 apertures.

[0050] Optionally, in one embodiment of this disclosure, the cage body 1 includes a support 11 and a breeding net 12. The breeding net 12 includes a side net and a bottom net. The bottom of the side net is connected to the circumferential edge of the bottom net, and the top of the side net is connected to the support 11. The side net and the bottom net together enclose the breeding space, and the installation port 13 is opened in the side net.

[0051] The support frame 11 supports the aquaculture net 12, allowing it to unfold and create an aquaculture space for the cultivation of aquatic organisms. The top of the aquaculture net 12 is open, allowing it to be close to the sea surface for convenient management of the cultured aquatic organisms.

[0052] In some examples, the mounting port 13 is square, but it can also be round, and the corresponding test hanger 2 is also round. After the mounting port 13 is closed by the test hanger 2, the test hanger 2 and the side netting form a whole. The aquaculture netting 12 can be made of polyethylene, and the aperture of the mesh 23 can be set according to the different aquatic organisms being cultured.

[0053] Optionally, in one embodiment of this disclosure, the support 11 includes a support body 111 and a floating member 112. The support body 111 has a ring structure, and a connecting part is provided at the top of the support body 111 for connecting with external hoisting equipment. The floating member 112 is connected to the support body 111 and is distributed in a ring around the circumferential edge of the support body 111.

[0054] The floating component 112 is used to support the support body 111 to float on the sea surface or water surface, so that the top of the aquaculture net 12 is close to the sea surface or water surface, thus realizing the aquaculture of aquatic organisms. With the floating component 112, it is not necessary to set up too many support structures to support the support body 111, so as to realize aquaculture in a natural environment and better simulate the natural aquaculture environment.

[0055] The designed connecting parts facilitate easy connection or separation with external hoisting equipment, allowing the entire test cage to be lifted by external hoisting equipment when observation of the test hanging plate 2 is needed, making it more convenient to use. In some examples, the connecting parts can be hoisting frames, facilitating connection with hooks or cables of external hoisting equipment. In some examples, the floating component 112 can be an HDPE floating pipe.

[0056] Optionally, in one embodiment of this disclosure, the test cage further includes an anchoring device, which can be connected to the cage body 1 so that the cage body 1 floats naturally in the ocean or water.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0058] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
