A shallow water steel pipe sinking net cage structure

Abstract

The invention discloses a shallow-water steel pipe sinking net cage structure, which comprises a concrete foundation, a torsion spring, an auxiliary support rod, a second return spring, a docking groove and an anti-skid pad. The concrete foundation is provided with an installation hole through which the installation hole An installation guide is connected in the middle, and the top of the installation guide is provided with a docking port, and the cage column is connected to the docking port, and the movable block is connected to the groove through the first return spring, and the movable block is connected to the card. In the groove, a fixed plate is installed on the outside of the column of the net cage, the outer frame is fixed on the end of the net clothing, and the top of the column of the net cage is welded with a walkway load-bearing beam. The shallow-water steel pipe submerged net cage structure has the characteristics of simple structure, no need for piling, strong wind and wave resistance, and the use of small ships for offshore assembly. The cost of manufacturing and offshore installation is low, and the net can be quickly installed. The connection between the column of the cage and the seabed is stable.

Description

technical field [0001] The invention relates to the technical field of shallow water fixed culture cages, in particular to a shallow water steel pipe sinking bottom cage structure. Background technique [0002] Aquaculture cage is an auxiliary device used in aquaculture to raise fish in marine captivity. Cage culture has the advantages of low cost, high output, convenient management and high catch rate. In recent years, cage culture has become popular in coastal areas. It has been widely used and developed rapidly in the field of aquaculture. There are floating and fixed cages for shallow water culture. The frame of floating cages is generally made of high-density polyethylene and other polymer materials, which has the advantages of mature technology and low cost. , but the ability to resist wind and waves is poor and the risk of aquaculture loss is high; while the fixed cage generally adopts the form of a steel structure frame, which has strong wind and wave resistance and ...
