Description

Technical Field

[0001] The present invention relates to the field of deep-sea aquaculture cage netting forms and marine life protection technical fields, and in particular to a detachable hanging sheet netting for aquaculture cages and a method for installing and replacing the netting. Background Art

[0002] Deep-sea aquaculture has open aquaculture waters, high-quality aquaculture water bodies, and high-end aquaculture outputs. It has been highly valued by coastal provinces and cities, and has developed rapidly, gradually replacing harbor aquaculture, and promoting the healthy and rapid development of the marine economy. In recent years, dozens of deep-sea aquaculture equipment have been put into use every year, including various types of bottom-mounted, semi-submersible and towing types. Continuous innovation and improvement have been made in the comprehensive utilization of aquaculture equipment, aquaculture models, the entire industrial chain and supporting equipment, and fishing and tourism platforms, offshore integrated platforms, wind-fishing platforms, 1+N radiation models and offshore factory models have emerged, fully developing marine energy, combining wind and waves, reducing costs and increasing efficiency, and bringing new opportunities for the industrialization of offshore aquaculture equipment.

[0003] Deep-sea aquaculture faces a longer offshore distance and complex and changeable sea conditions, which require aquaculture equipment to have stronger survivability, aquaculture fish to have higher wave and current resistance, more comprehensive production and living supporting capabilities, and more diversified energy supply capabilities. There is still a certain distance from truly forming an industrial scale. In terms of nets to prevent marine organisms, it has always been a pain point and difficulty in the industry. In addition to developing net materials with stronger resistance to biofouling, new special equipment such as cleaning robots are also being developed. When developing and designing aquaculture cages, the nets are rotated as a whole, and the biofouling of the nets is reduced by sun exposure, or the nets are exposed to the sun and marine organisms are cleaned by floating the semi-submersible structure as a whole. In the aquaculture process, the aquaculture mode is optimized to shorten the aquaculture season, or the aquaculture cages are idle through the transfer of aquaculture fish, and net cleaning is carried out. The cleaning of aquaculture nets often uses methods such as exposure to the sun, hammering, high-pressure water gun spraying, and even direct replacement of the entire net. The attachment of marine organisms to nets has always been a key focus in the field of marine aquaculture, and it is also an important cost and risk in the aquaculture process, which has not been well resolved. Summary of the invention

[0004] The invention provides a detachable hanging sheet net for aquaculture cage and an installation and replacement method thereof, which are used to solve the problems of cleaning the hanging sheet net to prevent marine organism attachment and installing and replacing the hanging sheet net.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In deep-sea aquaculture, the nets of aquaculture equipment are easily attached to marine organisms. At present, in order to solve this problem, we mainly start from two aspects: one is to continue to develop special materials to prevent biological fouling, hoping to reduce the attachment of marine organisms from the material; the second is to develop special equipment for cleaning robots, and use automated equipment to clean the nets with attached marine organisms.

[0037] Figure 1 is a schematic diagram of the structure of a U-shaped bracket in an embodiment of the present invention, Figure 2 FIG. 1 is a schematic diagram of the structure of the net frame in an embodiment of the present invention. Figures 1 to 2 As shown, an embodiment of the present invention provides a detachable hanging sheet net for aquaculture cage, which is used to solve the problem of cleaning the hanging sheet net to prevent marine biological attachment and the installation and replacement of the hanging sheet net, which specifically includes:

[0038] A U-shaped bracket 5 having a slot 7;

[0039] The net frame 2 can be inserted into the slot 7 of the U-shaped bracket 5. The net 3 is fixed in the net frame 2. The net frame 2 is a movable part of the hanging net and can withstand the tension of the net 3 and the impact of water flow. The U-shaped bracket 5 is a fixing part of the hanging net. The slot 7 provided therein can just be inserted into the net frame 2, ensuring that the net frame 2 can be firmly fixed in the slot 7 of the U-shaped bracket 5.

[0040] In one embodiment, the net frame 2 is provided with a hook 1 for hoisting, and the hook 1 is used to provide a tying rope or a hook 1 component when lifting and replacing the net frame 2, which is easy and efficient to operate.

[0041] Figure 3 FIG. 1 is a schematic diagram of the structure of a hanging mesh garment in an embodiment of the present invention. Figure 3 As shown, in one embodiment, the net frame 2 is provided with a first locking hook 4, and the U-shaped bracket 5 is provided with a second locking hook 6. The first locking hook 4 of the net frame 2 and the second locking hook 6 of the U-shaped bracket 5 are connected by a locking bolt 8. When the net frame 2 is inserted into the U-shaped bracket 5, two locking bolts 8 are used to form the whole of the hanging net.

[0042] In one embodiment, the material of the net 3 is a steel net, a galvanized steel net or a rope net.

[0043] Figure 4 This is a schematic diagram of the structure of the staggered and stacked installation of the hanging mesh in the embodiment of the present invention. Figure 5 This is a schematic front view of the installation of a detachable hanging net aquaculture cage in an embodiment of the present invention; Figure 6 FIG. 1 is a schematic top view of the installation of a detachable hanging net aquaculture cage in an embodiment of the present invention; Figures 4 to 6 As shown,

[0044] The embodiment of the present invention further provides a method for installing a detachable hanging sheet net for aquaculture cage, which is applicable to any of the above detachable hanging sheet nets for aquaculture cages, and specifically comprises the steps of:

[0045] At the side net of the aquaculture cage, multiple U-shaped brackets 5 are fixed by structural parts, and the net frame 2 is inserted into the corresponding U-shaped bracket 5 slot 7. It should be noted that in the vertical direction, two adjacent U-shaped brackets 5 should be staggered and fixed. This design makes the installation process of the hanging net on the aquaculture cage simple, stable and reliable. It is only necessary to use structural parts to weld and fix the U-shaped bracket 5 to the side net of the cage. It is particularly important to emphasize that when welding and fixing the U-shaped bracket 5, it is necessary to ensure that there is a misalignment in the vertical direction, that is, the upper edge of the U-shaped bracket 5 of the next layer of hanging net should be staggered and superimposed on the upper edge of the U-shaped bracket 5 of the previous layer of hanging net, so as to ensure that the net frame 2 of the next layer of hanging net can be smoothly pulled out and inserted. The staggered superposition installation method proposed in the embodiment of the present invention allows large pieces of net 3 to be split into small pieces of hanging net, and the hanging net that is severely contaminated by marine organisms can be replaced at any time, which greatly reduces the difficulty of cleaning marine organisms and is expected to solve the problem of marine organism attachment in deep-sea aquaculture cages.

[0046] In one embodiment, the side net of the aquaculture cage facing the open sea adopts a double-layer net 3, and the side net of the internal aquaculture cage adopts a double-layer net 3 or a single-layer net 3. In order to enhance the safety of the net 3, the side of the aquaculture cage facing the open sea usually adopts a double-layer net 3 structure to improve safety redundancy, and at the same time reduce the frequency and time requirements for replacing the net 3. As for the isolation net inside the cage, a single-layer or double-layer net 3 can be selected according to actual needs. The net 3 on the net frame 2 can be made of nylon net rope, copper net or galvanized steel net. The key is to facilitate the replacement and cleaning of the hanging piece of the net 3.

[0048] The embodiment of the present invention further provides a method for replacing a detachable hanging sheet net for aquaculture cage, which is applicable to any of the above detachable hanging sheet nets for aquaculture cages, and comprises the steps of:

[0049] The hook 1 on the net frame 2 of the biofouled hanging net is hung on the traction hook of the movable hanging net traction machine, and the threaded connection between the net frame 2 and the U-shaped bracket 5 is loosened;

[0050] The net frame 2 is lifted by the movable hanging net traction machine, and the intact hanging net is replaced;

[0051] The net frame 2 of the intact hanging net is inserted into the slot 7 of the U-shaped bracket 5 by the movable hanging net traction machine, and the threaded connection between the net frame 2 and the U-shaped bracket 5 is tightened.

[0052] When a diver needs to clean part of the hanging net, he can use a good hanging net to replace it. The replaced hanging net with serious biofouling should be cleaned for subsequent recycling. The following is the complete hanging net replacement process:

[0053] The first step is that after the diver enters the water, he or she will hook the hook on the net frame of the severely biofouled hanging net to the traction hook, connect it to the movable hanging net traction machine, and loosen the locking bolt, such as Figure 7 shown.

[0054] The second step is to lift the net frame through the movable hanging net traction machine and replace it with a good hanging net, such as Figure 8 shown.

[0055] The third step is to slowly insert the net frame of the new hanging net into the U-shaped bracket slot through the movable hanging net traction machine, and then the diver locks the locking bolt to complete the replacement of a hanging net. Fig. 9 shown.

[0056] After the replaced hanging net with serious biological fouling is cleaned, the next piece of net is replaced. This cycle is repeated until all the hanging nets with serious biological fouling are replaced. It should be noted that if there are extra hanging nets for turnover, the replacement efficiency can be further improved.

[0057] In summary, the present invention splits large pieces of netting into small pieces of hanging netting, and adopts an installation method in which the upper and lower layers are staggered and superimposed, so that each piece of hanging netting can be replaced at any time. When the hanging netting with serious attachment of marine organisms needs to be replaced, the diver only needs to fix the hanging netting, and the surface staff can pull it up and quickly insert the cleaned hanging netting to complete the replacement. After cleaning the replaced hanging netting, continue to replace the next hanging netting until all the hanging netting with serious attachment of marine organisms have been replaced. In this way, the overall netting of the aquaculture cage can be unobstructed, ensuring good water exchange, reducing maintenance costs, improving reliability, and can be replaced at any time. The present invention will lead the development of deep-sea aquaculture technology and help realize the strategy of building a strong maritime nation.
