Floating-sinking net cage for deep sea culture

Abstract

The invention relates to the technical field of marine culture equipment, and discloses a floating-sinking net cage for deep sea culture. The floating-sinking net cage comprises a central support column and an inner net, the bottom of the central support column is movably connected with a sliding device in a sleeved mode, a first supporting device is movably connected to the position, located above the sliding device, on the central support column, and the top of the central support column is fixedly connected with a second supporting device. Through the arrangement of the central support column, the first supporting device and the second supporting device, the net cage has a middle supporting structure, the structural strength of the net cage is greatly enhanced, and the net cage can resist higher-level stormy waves and can adapt to the changeable weather of deep sea and the rapid change of ocean currents in a water area; and meanwhile through the arrangement of a first solenoid valveand a second solenoid valve, the buoyancy of the net cage can be adjusted, the net cage sinks into the seabed before typhoon comes and is prevented from being in direct contact with stormy waves, then the net cage is protected, the protection performance of the net cage is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine aquaculture equipment, in particular to a floating net cage for deep sea aquaculture. Background technique [0002] Deep-sea aquaculture cages refer to aquaculture cages that can be used in relatively deep sea areas (usually the depth of the sea area is greater than 20m). Due to the oversaturation of offshore cage culture, it has a greater impact on the environment. It is of great significance to reduce environmental pressure, protect and adjust the structure of marine culture species. At present, deep sea culture cages are composed of frame system, mesh bag, fixing system and supporting facilities. to a limited depth underwater, but there are some deficiencies in its use, as follows: [0003] The fixed platform uses a polyethylene hollow tube to form a circle with a large diameter, so that the cage floats on the sea level. When the circle with a huge diameter lacks a support structure in the midd...

Problems solved by technology

[0003] The fixed platform uses a polyethylene hollow tube to form a circle with a large diameter, so that the cage floats on the sea level. When the circle with a huge diameter lacks a support structure in the middle, it will be beaten by large waves in windy waves or even typhoon weather. , will still be bent and damaged, but due to the need to pull the net for fishing, adding a structure in the middle will hinder fishing, so its structural strength is low and cannot meet the needs of deep-sea farming. At the same time, when using net cages for farming , in order to increase the growth rate and density of the fish school, they will feed the feed, so that the nutrition around the cage will be richer, and it will attract wild fish to the vicinity of the cage, and it is easy to be eaten by wild fish, which will hit the cage and cause the net The capsule is damaged, and the current cages are mostly composed of single-layer nets in order to avoid the structure being too complicated. Once the mesh capsule is broken, the cultured fish will escape and cause huge losses.
