Guiderail type typhoon-resistant deep water cultivation intelligent net cage

Abstract

The invention provides a guiderail type typhoon-resistant deep water cultivation intelligent net cage. The guiderail type typhoon-resistant deep water cultivation intelligent net cage comprises a netcage frame, an automatic lifting control system and a guide column type mooring device and is characterized in that the automatic lifting control system can drive the net cage frame to ascend and descend, and the guide column type mooring device limits the ascending and descending trajectory of the net cage frame; the net cage frame comprises a net cage body and a net coat; the automatic lifting control system comprises load-adjusting floating boxes evenly distributed on a lower regular-polygon-shaped frame, the bottom of each load-adjusting floating box is provided with seawater inlets / outlets, and air inlet / outlet tubes are mounted at the top of each load-adjusting floating box; ascending and descending of the net cage frame are achieved by controlling the air intake and water dischargeand the water intake and air discharge of the load-adjusting floating boxes; the guide column type mooring device comprises guide columns fixed in the seabed, a guide sleeve mechanism, a primary variable loading mechanism and a secondary variable loading mechanism. The guiderail type typhoon-resistant deep water cultivation intelligent net cage can ascend and descend automatically and be stabilized at an appointed position and is especially suitable for resisting typhoon with the wind force scale being 14-17.

Description

technical field [0001] The invention relates to a deep-water aquaculture net cage, in particular to a guide-rail type anti-typhoon intelligent deep-water aquaculture net cage, which is suitable for resisting wind and waves above level 14 and belongs to the technical field of marine aquaculture. Background technique [0002] At present, cages are mostly used in offshore and harbor aquaculture in various countries in the world. Due to the small amount of water exchange in offshore waters, especially in harbors, fish diseases are increasing day by day, and environmental pollution is becoming more and more serious. Aquaculture is no longer sustainable, so countries begin to develop offshore to deep sea farming. Deep-sea aquaculture cage refers to the aquaculture cage that can be used in relatively deep sea areas (usually the depth of the sea area is greater than 20m), and it is aquaculture equipment that has developed rapidly in the past ten years. It uses computers, new materi...

AI Technical Summary

Problems solved by technology

[0003] However, so far, there is no real example of a large deep-water cage that can successfully resist wind and waves above level 14. There are four main reasons: ① The strength and rigidity of the cage are limited

The current net cages use PVC and other organic materials in the near shore and harbors, which makes the frame structure of the net cages unable to withstand the impact of typhoons and waves above level 14; ②The strength of net clothing is insufficient

The current nets are made of nylon (PA), polyethylene (PE) or polypropylene (PP), which are often torn in strong winds and waves, causing fish to escape;

In the typhoon season, deep sea waves and big fish collide with each other in the cage, resulting in a high mortality rate of the fish school

④The mooring system has insufficient resistance
