Buoyancy regulation and control lifting type breeding caisson and operation method thereof

Abstract

The invention discloses a buoyancy regulation and control lifting type breeding caisson. The buoyancy regulation and control lifting type breeding caisson comprises a breeding box body and a balance weight part; the balance weight part is hung below the breeding box body; the breeding box body comprises a box body supporting frame, a netting box body, a constant-capacity buoyancy cabin and a variable-capacity buoyancy cabin; the box body supporting frame comprises a center column, a steel skeleton frame and a middle ring frame; the upper end of the center column is connected with the steel skeleton framework; the variable-capacity buoyancy cabin is connected with the lower end of the center column; the middle ring framework is fixedly connected in the circumferential direction of the outer side of the variable-capacity buoyancy cabin; the constant-capacity buoyancy cabin is arranged between the steel skeleton framework and the variable-capacity buoyancy cabin and can slide in a lifting mode along the center column; a traction strip is arranged between the steel skeleton framework and the middle ring framework; the netting box body is expanded around the center column to be installed and connected; and the variable-capacity buoyancy cabin is provided with air inlet and outlet pipes and water inlet and outlet pipes. The breeding caisson is high in typhoon and huge wave resistance, good in ocean current deformation resistance and easy and convenient to manage and operate, has the advantages of being safe in production, efficient in breeding and easy and convenient to manage, and is suitable for being popularized and applied to coastal breeding.

Description

technical field [0001] The invention relates to the technical field of aquatic product breeding caissons. Background technique [0002] In recent years, with the construction of various large-scale aquaculture facilities at home and abroad, the aquaculture industry has opened the prelude to enter the deep sea and expand the aquaculture space outside the bay. Expanding the development of famous and high-quality aquatic product farming outside the bay and in the far-reaching sea area is to break the current shallow sea farming that can only be concentrated in the harbor and near-shore waters, resulting in shallow sea aquaculture industry "overloading of harbor farming, super-saturation of near-shore farming, and offshore farming outside the bay." The main measures for the structural bottleneck of "severely insufficient development" are also effective ways to adjust the production structure of the mariculture industry, promote the supply-side reform of the mariculture industry,...

Problems solved by technology

[0003] my country began to develop deep-water cage culture outside the bay from the end of the last century, and designed and developed a variety of breeding caissons outside the bay and carried out demonstration breeding. However, with the passage of time and the expansion of scale, the breeding equipment in the sea outside the bay of our country is insufficient in anti-typhoon capabilities, Problems such as poor adaptability to strong ocean currents in sea areas, and lack of targeted storm-resistant cage culture and management technology and regulations have become increasingly prominent, seriously restricting the healthy development of high-efficiency farming in waters outside the bay of my country. In recent years, large-scale marine engineering equipment manufacturing companies have entered deep sea Breeding equipment, but its ultra-high investment in facilities and equipment cannot meet the mass breeding production requirements of small and micro farming enterprises or farmers
