Embodiment Construction

[0022] In the figure, 1, main floating pipe; 2, main floating pipe tee 3, spring 4, safety rope 5, connecting rope 6, connecting joint 7, guardrail pipe tee 8, guardrail pipe 9, net hook 10, guardrail post Tube; 11, column pin 12, positioning block.

[0023] see Figure 1-Figure 7 , a flexible connection square net cage frame, the main floating pipe 1 has 4 sections of independent HDPE straight main floating pipes, each of the two ends of the straight main floating pipe 1 is equipped with a connecting joint 6, and is integrated with it by hot-melt welding. The outer end of the connector 6 is provided with a criss-cross semicircular ring. The head and tail of each straight main floating pipe 1 are movably connected as a whole through the connecting piece, and each section of the straight main floating pipe can be moved relative to each other to form a quadrilateral net cage frame. The specific connection method is: the two adjacent connecting joints 6 of the two sections of s...

Abstract

The present invention provides a flexible connected net cage frame, it includes main floating tube, main floating tube three-way, guard bar tube, guard bar tube three-way and guard bar upright column tube. It is characterized by that the described main floating tube at least has four independent vertical main floating tubes which are head-to-tail successively movably connected together by means of connecting components, and can be relatively moved between them to form polygon net cage frame having at least four sides, and every side can be independently moved with wave so as to raise its capability for resisting wave.

Description

technical field [0001] The invention belongs to the improvement of the frame structure of seawater culture net cages, in particular to a flexible connection net cage frame. Background technique [0002] At present, there are various types of cage structures used in aquaculture in the world. There are square traditional cages with moso bamboo, plank or steel pipe structure, as well as advanced HDPE circular cages, dish cages in the United States, and tension leg cages in Norway ( TLC) cages, Farmocean cages in Sweden, boat-shaped combined cages in Japan, flexible rope cages in Taiwan Province and various lifting cages, etc. Compared with the traditional square net cages, although these advanced net cages have better anti-wind and wave performance, due to the complex structure of the net cages, the requirements for manufacturing, installation and laying are relatively high, and most of them are expensive. Therefore, to some extent Its development and application are limited. ...
