Semi-rigid composite polyester net cage and assembling process thereof

Abstract

The invention relates to a semi-rigid composite polyester net cage and an assembling process thereof. The semi-rigid composite polyester net cage comprises a net bag, which is composed of a side net and a bottom net, wherein the side net is formed by splicing a plurality of net pieces, which are formed by assembling a plurality of nettings, and the netting are woven from polyester threads. According to the semi-rigid composite polyester net cage, from the nettings to the net pieces then the side net, and then by means of the assembling structure and the assembling method of the side net and the bottom net, the overall strength of the net bag can be improved, the semi-rigid composite polyester net cage can resist windstorm and waves and avoid damage caused by tearing; meanwhile, an appliededge sealing manner can avoid direct contact and abrasion between the net bag and a net cage frame, thereby reducing wearing of the net bag and avoid loss brought about by release of the net bag.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a semi-rigid composite polyester cage and an assembly process thereof. Background technique [0002] As my country's fishery development strategy shifts from fishing to farming, my country's sea and freshwater cage culture is showing a rapid development trend; in the process of fish farming, fishing nets are used to capture, drive, isolate, gather , grading and other functions, especially in mariculture, it has now developed from small net cages near the shore and in harbors to deep water culture in the open sea; the breeding volume of a single net cage has developed from tens of cubic meters to hundreds of cubic meters to thousands of cubic meters; The water depth of the breeding waters extends from a few meters to 20-30 meters waters, and is developing towards deeper waters. [0003] With the enlargement of breeding cages and the deepening of breeding waters, the numb...

AI Technical Summary

Problems solved by technology

[0004] 1. The structural strength of the net cage is low, and it cannot withstand storms and waves, causing the fishing net to tear;

[0005] 2. The connection strength between the cage and the mooring system is low, and it is easy to drift directly under the wave attack. After the cage is displaced, the frames collide with each other, causing the cage to be damaged;

[0006] 3. The connection structure between the net cage and the net cage frame is not stable, and the net bag on the net cage is affected by the current and waves, and it is in contact with the net cage frame all the time. Since the net bag is made of semi-rigid material, the net cage frame It is made of soft material, and the connection between the two is easy to be disconnected due to friction, causing the net bag to escape from the escaped fish
