Description

Deep sea aquaculture sinking platform

technical field

The utility model relates to the field of marine aquaculture equipment, in particular to a deep-sea aquaculture ups and downs platform.

Background technique

With the development of marine economy and the construction of ports, large-scale chemical and steel plants in near-shore and inland bay areas, the area of sea areas that can be cultivated has been continuously reduced and sea water pollution has been caused. For the "lost sea fishermen", the livelihood and employment project has become the responsibility of the local government, while the utilization rate of the deep-sea aquaculture space is very low. protrude.

In the following years, marine aquaculture developed. In the offshore area or around the island (-10 meters), fishermen used piling to fix uprights on the seabed, and then used nets to form a large and large-volume fence-type cage equipment, which was strong against wind and waves, and the seawater flow rate Fast, plankton is sufficient, and the breeding ecology is good, which is conducive to the growth of fish.

Large-scale offshore aquaculture fence-type cage equipment, its structural characteristics: large-scale and large-volume aquaculture cage equipment, suitable for construction in offshore waters, but in deep sea (-20 meters above) construction, it cannot effectively avoid risks and encounter harsh sea conditions. In times of typhoon (such as typhoon), the structural strength of the cage cannot withstand the impact of strong typhoon; secondly, with the rapid development of the maritime transportation industry and the island tourism industry, the government has requisitioned a large area of offshore and the surrounding waters of the island as a waterway, and its equipment The promotion is limited by policy and the depth of the sea area.

At the end of the 20th century, Hainan Province took the lead in introducing a batch of large-scale wind and wave-resistant deep-water cages (HDPE type) from Norway, which were upgraded from ordinary small cages to large-scale wind and wave-resistant cages. From near-shore and offshore to deep-sea, to promote the employment of fishermen.

Large-scale deep-water aquaculture cage equipment, its structural characteristics: HDPE type deep-water cages, floating frames made of high-density polyethylene materials, have limited strength, and at the same time, there are too many structural nodes, and most of them are fixed by hot-melt technology in the production process. The connection is easy to deform under the impact of strong wave current, and the larger the volume of the cage, the more easily the floating frame is deformed. Therefore, the volume of the deep-water cage and the depth of the sea area are limited to a certain extent.

In 2017, the world's first super-large fully automatic deep-sea semi-submersible "Ocean Fishery No. 1" was successfully delivered, marking China's marine aquaculture industry from the deep sea to the deep sea to expand the breeding space (below -30 meters deep), expand the breeding sea area, protect the And to improve the ecological environment of marine aquaculture, the fish products it breeds are close to natural, and it is called imitating ecological fish, improving the quality of fishery products, and increasing income.

Super-large deep-water aquaculture cage fishery, its structural characteristics: steel structure design, large-capacity water cages, adapt to the harsh sea conditions of wind resistance and wave resistance, in order to increase the water volume of the cages, under the condition that the structural plane area remains unchanged, only Increase the height (depth) of the cage structure, increase the height (depth) of the cage, increase the difficulty of design, and increase the amount of material of the steel structure, thereby increasing the construction cost, large investment, single function of the cage, limited to breeding, and comprehensive benefits. Obviously, its equipment users are powerful, and large-scale breeding enterprises may only benefit from a small number of fishermen's breeding professional households.
