Description
Technical Field
The invention relates to the technical field of ocean engineering and aquaculture engineering, in particular to a device for combining a single pile type fan foundation with a net cage group.
Background
The coastline of China is long and wide, and the ocean resources are rich. The people take food as the day, and with the increasing living standard of people, the production quantity of marine aquatic products can not meet the current demand of people. The cultivation scale of a single net cage is small, and the current required large-scale cultivation of the marine pasture cannot be effectively achieved. Therefore, marine product cultivation by using the net cage group has become a main mode of artificial pasture cultivation, but in recent years, due to rapid development of offshore net cage cultivation, some defects of offshore cultivation are gradually exposed, and due to the fact that the density of the net cages is increased, the trend of the net cage group type marine pasture to deep open sea has become great. The main problem faced by deep sea cage group culture is that the structure of the cage group is damaged due to overlarge wind waves. Most fish grow in the sun and air, so the net cage sometimes floats on the sea surface; however, when typhoons come, the net cage needs to sink again to avoid damage to seafood and its own structure. In addition, benthic sealiving things such as sea cucumbers and oysters need to be cultivated near the seabed.
In recent years, the development of offshore wind power generation has been rapid. In 2021, the new installed capacity of the global offshore wind power is 21.1 gigawatts, the same ratio is increased by two times, the specific gravity of the new installed capacity of the global offshore wind power reaches 22.5%, and the maximum increase of the history is created. By the end of 2021, the global offshore wind power accumulated installed capacity reaches 57 gigawatts, the same ratio is increased by 58%, and the ratio of the offshore wind power in the global wind power total installed is increased to 7%. The development of offshore wind power is not only beneficial to low-carbon transformation of energy sources, but also can strengthen the energy source supply safety. With the progress of technology, offshore wind power generation breaks through in water depth and offshore distance, and site selection has been developed to open sea deep sea. At present, the foundation forms of the offshore wind turbine comprise a single pile type, a gravity type, a suction type and a conduit frame. Compared with other types, the single pile type pile has the advantages of simple structure, quick construction and relatively low manufacturing cost. Currently, the sea area of the offshore wind power plant is only used for offshore wind power generation, and along with the gradual development of ocean resources in recent years, the efficient utilization of the ocean resources has become great trend, and the ideal sea area is only used for single purpose of offshore wind power generation and is unfortunately; for the net cage for mariculture, the influence of stormy waves often causes the trouble that the position of the net cage is moved, so that the development of the mariculture industry is limited. The device combining the single pile type fan foundation and the net cage group is developed, and has great potential and practical application value.
