A kind of transfer channel for aquaculture fish that connects circular floating net cages

Abstract

The invention discloses a fish breeding transition channel which makes round floating type net cages mutually connected. The fish breeding transition channel comprises a transition channel framework, the transition channel framework is welded through steel pipes to constitute a three-section middle symmetric structure, wherein the channel section is in a hollow cylinder outline shape, the inlet / outlet sections at the two ends are in an enlarged horn opening shape which is gradually and aslant expanded to the lower portion, and fixed pipes are symmetrically arranged at the portion, close to the two end openings, at the top of the transition channel framework; net clothes cover the periphery of the transition channel framework, floating cylinders are further arranged at the two sides of the transition channel framework, and fixed frames which are distributed at intervals and matched with the lower portion outline of the transition channel framework are arranged between the outer walls of the floating cylinders; when the fish breeding transition channel is in use, the two ends of the fish breeding transition channel are in butt joint with butt-joint holes with the same size as the two round net cages respectively, and after work is finished, separation and independence of both round net cages can be restored. Both round net cages are communicated with each other, multiple kinds of operation including net clothes replacement and cage separation work are facilitated, and the work efficiency is high.

Description

Technical field: [0001] The invention relates to seawater culture net cages, and more particularly relates to a cultured fish transfer passage for connecting circular floating net cages to each other. Background technique: [0002] The cylindrical shape surrounded by the circular frame and the net clothing, and the cage floating on the water surface are called circular floating cages. In my country, the most widely used circular floating cages are HDPE frame circular floating cages, whose circumference is usually 40-100m, and of course, large deep-water cages with a circumference of more than 100m have gradually been developed. Regarding the technical development of the circular floating cage system, the following issues deserve attention: [0003] 1. The independence of each cage in the cage group: [0004] Usually, four or more circular cages can be joined together to form a cage group, which can use a unified mooring system. Due to the large volume of a single cage (up...

Problems solved by technology

It is necessary to replace the old nets on the sea, especially when the wind is high and the waves are high, and install the new nets. It is manual operation, which is labor-intensive, and the personal safety of the breeding workers is poor, and it is necessary to prevent the breeding of fish. escape
