A net cage structure for easy removal of barnacles

Abstract

This utility model relates to the field of marine ranching technology, and in particular to a net cage structure for easy removal of barnacles. It includes a steel truss, multiple support columns installed at the bottom of the steel truss, connecting frames installed between the support columns, and an inner net installed between the connecting frames. Each support column has a square face near the connecting frame, and the connecting frame is a square frame. The square face of the support column is fixedly connected to the outside of the connecting frame. In this utility model, the support columns, square faces, and C-shaped scrapers can surround the support columns, making the overall operation of the device more stable. Because barnacles have a strong adhesion to rigid objects, this design also ensures that most barnacles grow on the outside of the support columns, reducing the number of barnacles attached to the inner net. When the net cage is completely lifted off the sea surface, the barnacles on the support columns can be completely scraped off, making the cleaning of the net cage more convenient and improving the work efficiency of the workers.

Description

Technical Field

[0001] This utility model relates to the field of marine ranching technology, specifically to a net cage structure that facilitates the removal of barnacles. Background Technology

[0002] Marine cages, also known as ocean cages or fish farming cages, are large-scale, enclosed aquaculture facilities set up in natural sea areas. The cages use huge nets to create a closed or semi-closed aquatic space, confining the farmed fish for intensive cultivation. This model fully utilizes the superior water quality, high dissolved oxygen levels, and strong self-purification capacity of open sea areas, allowing fish to grow in a near-natural environment. Therefore, it features large farming capacity, high-quality fish, and rapid growth.

[0003] During the use of existing net cages, a large number of barnacles will adhere to their netting and the uprights supporting the netting. The barnacles have low adhesion to the netting and can be washed off by high-pressure water guns, but the barnacles attached to the uprights are difficult to remove and require workers to manually remove them using ladders or cranes, which is inefficient. Therefore, a net cage structure that facilitates the removal of barnacles is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a net cage structure that facilitates the removal of barnacles, thereby solving the problem mentioned in the background art of the difficulty in cleaning barnacles attached to the uprights of existing net cages.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A net cage structure for easy removal of barnacles includes a steel truss, multiple support columns installed at the bottom of the steel truss, connecting frames installed between the multiple support columns, and an inner net installed between the multiple connecting frames. The support columns have a square face on the side near the connecting frame. The connecting frame is a square frame. The square face of the support column is fixedly connected to the outside of the connecting frame. A C-shaped scraper is provided on the outside of the support column.

[0007] Preferably, the inner network is fixedly connected to the square surface of the support column via a connecting layer.

[0008] Preferably, the inner side of the C-shaped scraper and the outer side of the support column are in contact with each other.

[0009] Preferably, the width of the square face is smaller than the diameter of the support column.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, the support columns, square face and C-shaped scraper can be set to surround the support columns, making the overall operation of the device more stable. Since barnacles have a large adhesion to rigid objects, this design can also make most of the barnacles grow on the outside of the support columns, reducing the number of barnacles attached to the inner net. When the net cage is completely lifted off the sea surface, the barnacles on the support columns can be completely scraped off, making the cleaning of the net cage more convenient and improving the work efficiency of the workers.

[0012] 2. In this utility model, the contact area between the square connecting frame and the square surface of the support column is large, which makes the overall structure of the cage more stable and helps to resist the impact of sea waves.

[0013] 3. In this utility model, the inner net can be fixed to the square surface of the support column by the connecting layer, thereby avoiding the difficulty in cleaning barnacles growing in the gap between the square surface and the inner net. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A wire mesh cage structure for easy removal of barnacles includes a steel truss 1, multiple support columns 2 installed at the bottom of the steel truss 1, connecting frames 3 installed between the support columns 2, and an inner mesh 4 installed between the connecting frames 3. Each support column 2 has a square face 21 on the side near the connecting frame 3. The connecting frame 3 is a square frame. The square face 21 of the support column 2 is fixedly connected to the outside of the connecting frame 3. A C-shaped scraper 6 is provided on the outside of the support column 2, with the inner side of the C-shaped scraper 6 and the outer side of the support column 2 fitting together. The width of the square face 21 is smaller than the diameter of the support column 2. The structure utilizes the support columns 2, square face 21, and... The C-shaped scraper 6 can surround the support column 2, making the overall operation of the device more stable. Since barnacles have a strong adhesion to rigid objects, this design also allows most barnacles to grow on the outside of the support column 2, reducing the number of barnacles attached to the inner net 4. When the net cage is completely lifted off the sea surface, the barnacles on the support column 2 can be completely scraped off, making the cleaning of the net cage more convenient and improving the work efficiency of the workers. Through the setting of the connecting frame 3, the contact area between the square connecting frame 3 and the square surface 21 of the support column 2 is large, which can make the overall structure of the net cage more stable and help resist the impact of sea waves.

[0024] The inner net 4 is fixedly connected to the square face 21 of the support column 2 through the connecting layer 5. By setting the connecting layer 5, the inner net 4 can be fixed to the square face 21 of the support column 2, thereby avoiding the difficulty in cleaning barnacles growing in the gap between the square face 21 and the inner net 4.

[0025] Workflow: When using the structure described in this application, the C-shaped scraper 6 needs to be installed on the marine ecological platform. A lifting device is then used to hoist the steel truss 1 and its connecting components into the platform, ensuring the inner side of the C-shaped scraper 6 and the outer side of the support column 2 are in contact. The cage can then be used normally. The large contact area between the square connecting frame 3 and the square face 21 of the support column 2 makes the overall structure of the cage more stable and helps resist the impact of waves. The design of the connecting layer 5 fixes the inner net 4 to the square face 21 of the support column 2, thus preventing barnacles from growing in the gaps between the square face 21 and the inner net 4, which are difficult to clean. After a period of use, barnacles will grow on the outer layer of the inner net 4 and the connecting frame 3, as well as on the surface of the support column 2. At this time, a lifting device can be used... The steel truss 1 is lifted. During this process, the C-shaped scraper 6 can scrape off the barnacles on the outside of the support column 2. In this application, the width of the square face 21 is smaller than the diameter of the support column 2. This design allows the C-shaped scraper 6 to surround the support column 2, enabling the net cage to move vertically and making the overall operation of the device more stable. Since barnacles have a large adhesion to rigid objects, this design also ensures that most barnacles grow on the outside of the support column 2, reducing the number of barnacles attached to the inner net 4. When the net cage is completely lifted off the sea surface, the barnacles on the support column 2 can be completely scraped off. At this time, workers can use a high-pressure water gun to clean the area on the net cage where barnacles have grown. The design of this application makes the cleaning of the net cage more convenient and improves the work efficiency of workers.
