Example Embodiment

[0034] The present invention will be further described below in conjunction with the drawings.

[0035] figure 1 Shown is an overall perspective view of the present invention. The invention includes a cylindrical floating module and a self-elevating net cage. The cylindrical floating module is welded by traditional steel and has two inner and outer shells to provide buoyancy and structural rigidity for the entire fishing ground to resist environmental loads. Cylindrical floating modules surround the jack-up cage to provide support for the cage to resist loads caused by waves and currents.

[0036] Above the cylindrical floating module, four superstructures are evenly distributed on the main deck of the cylindrical floating module. The largest main superstructure 1 is used to arrange the engine room, workshop, dead fish handling system, control system, communication system and housing. The three small superstructures are feed storage rooms 2, which are used to store fish feed. T...

Abstract

The invention belongs to the field of mariculture, particularly relates to a cylinder floating type module, and further relates to a cylindrical floating type fishery of a self-lifting net cage. The cylinder floating type module is provided with open pores near a waterline, which can prolong the natural period of the vertical motion of the fishery, thereby reducing motion response of the fishery under the operation and extreme working conditions. The self-lifting net cage structure can be completely locked on the joint position of the upper portion and lower portion of the cylinder floating type module. When fish is completely removed from the net cage, the net cage can be dried in the sun or frozen for disinfection, and a netting can also be checked and maintained very easily. The cylindrical floating type fishery of the self-lifting net cage has the advantages that under various different environmental working conditions, the net cage maintains a constant capacity, thereby ensuring that shoals of fish are not affected by the net cage movement and volume change and live in a low-pressure environment.

Description

technical field [0001] The invention belongs to the field of mariculture, and in particular relates to a cylindrical floating module. The invention also relates to a cylinder type floating fishery with self-elevating net cages. Background technique [0002] Mariculture is an important way to meet the growing global demand for seafood. Marine aquaculture owners are paying more and more attention to expanding the scale of aquaculture and expanding the field of aquaculture. Due to the destruction and over-exploitation of the near-shallow sea environment, the near-shallow sea areas suitable for mariculture have become increasingly limited. Therefore, many countries have gradually pushed the mariculture industry to the deep sea area with a good breeding environment. The environmental conditions in deep and open sea areas are harsh, and there are higher requirements for breeding facilities and operators. Through the research and development of deep-sea aquaculture facilities, ...
