Description

Deep sea purse seine aquaculture cage floating platform equipment

technical field

The utility model relates to the field of marine aquaculture equipment, in particular to a floating platform equipment for deep-sea purse seine aquaculture cages.

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" built by China Shipbuilding Industry Corp. for Norway's Slmar Group was successfully delivered, marking the expansion of China's marine aquaculture industry from deep sea to deep sea (-30 Below meters depth) breeding space, expand the breeding sea area, protect and improve the ecological environment of the sea area, and the fish products it breeds are close to natural, which are called imitation ecological fish, improve the quality of fishery products, and increase 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.

6. The drift positioning mooring system is added. The drift positioning mooring system is composed of multiple auxiliary anchor chains of different lengths and the auxiliary anchor body connected to the bottom of the auxiliary anchor chain. When the platform floating body sinks to a certain depth, the platform mooring system 2 The anchor chain is in a slack state. In order to prevent the floating body of the platform from being driven by the ocean currents on the seabed, resulting in deformation of the marine aquaculture device; a number of auxiliary anchor chains of different lengths have been added to ensure that the floating body of the platform has an auxiliary anchor that roughly matches its depth when lowered to any depth. The chain cooperates with it to hold it in place.

7. The streamline body structure is added to the wave-facing surface of the floating body of the platform, which can alleviate the impact and damage of the floating body of the platform by the waves.

8. The back of the platform floating body is the docking surface for docking ships. The wave energy on this surface has been absorbed by the platform floating body, and the waves are small, which is convenient for ships to dock.

9. The floating body of the platform is provided with a working channel that runs through up and down, and an escalator is arranged on the working channel. It is convenient for the staff to sneak below the sea surface for operations.

10. The side wall of the platform floating body is provided with at least one water inlet, and the water inlet is provided with a sealed safety door that is opened by force, and the sealed safety door is connected to the anchor body of the platform mooring system through a safety chain. When the mooring system of the platform finds damage, the floating body of the platform may drift on the sea surface. The movement of the floating body of the platform will cause the safety chain to straighten and cause the safety door to be separated from the water inlet. When seawater is poured into the water inlet, the floating body of the platform will sink. The platform float is displaced.

11. The counterweight is added to ensure that when the marine aquaculture device sinks, the counterweight falls into the seabed to avoid the deformation of the marine aquaculture device caused by the surging of the seabed current.
