Energy self-sufficient type modular spliced deep sea fishery breeding work ship

Abstract

The invention relates to an energy self-sufficient modular spliced deep sea fishery breeding work ship which comprises a semi-submersible bow, flexible connecting devices and semi-submersible modular net cages, the semi-submersible bow and the semi-submersible modular net cages are connected through the flexible connecting device, and the adjacent semi-submersible modular net cages are connected through the flexible connecting device; the semi-submersible bow comprises a superstructure, a semi-submersible main body, a mooring device, a bow power device and a power generation device. The superstructure is installed in the upper portion of the semi-submersible body, the mooring device is installed in the head portion of the semi-submersible body, the bow power device is installed at the bottom of the semi-submersible body, and the power generation device provides power for the ship. The semi-submersible modular net cage comprises a semi-submersible platform and a net cage power device, and the net cage power device is installed at the bottom of the semi-submersible platform. The position can be continuously changed according to change of sea conditions and weather, effective water body exchange is guaranteed through the weather vane effect, towing is facilitated, and wave additional bending moment shearing force is weakened.

Description

technical field [0001] The invention belongs to the technical field of aquaculture workboats, and in particular relates to an energy self-sufficient modular spliced ​​aquaculture workboat suitable for deep sea aquaculture. Background technique [0002] In recent years, the marine ecological problems faced by inner bays, tidal flats and other offshore aquaculture waters have become more and more serious. Unfavorable conditions such as inland pollutant discharge, offshore oil spills, radioactive nuclear substances and self-sourced pollution from mariculture have greatly reduced the available space for offshore aquaculture. Therefore, it has become an inevitable choice for development to expand the development space of marine fishery, improve quality, reduce pollution, develop new marine fishery farming technology and equipment, and make mariculture move from harbor and offshore to deep and open seas. [0003] At present, large-scale deep-water net cages and breeding ships have...

Problems solved by technology

[0003] At present, large-scale deep-water net cages and breeding ships have been put into use. The disadvantage of the existing large-scale deep-water net cages is that they are fixed in one position for a long time, and the seawater temperature varies greatly with the seasons, which is not conducive to the growth of cultured fish and produces Fish feces and residual bait will pollute the nearby waters, resulting in eutrophication of the water body, and when a typhoon hits, the cages will be destroyed, and the fish will die or escape; the existing large-scale farming ships are difficult to tow due to their huge size , and because the length of the ship is too long, the additional bending moment and shear force of the wave is relatively large, which poses a great threat to the longitudinal bending strength of the hull
