Elastic tying fixed-connecting shallow-sea aquaculture purse seine

Abstract

The invention discloses an elastic tying fixed-connecting shallow-sea culture purse seine. The aquaculture purse seine comprises pile columns and netting connected with the pile columns. A rope sleeveis arranged on each pile column; one side of each rope sleeve is connected with an elastic rope, and the other end of the elastic rope is connected with the netting; and the connecting parts of the elastic ropes with the netting are connected with floating bodies through a steel rope, and the bottom of the netting is tied to an iron chain which is embedded in the seabed. The rope sleeves are connected with the elastic ropes, so that the flexibility of the elastic ropes are utilized to improve the mobility of the whole purse seine, the netting can float with wave to buffer and weaken the waveforce and the water flow force to the netting, and thus the wind wave resistant and the tidal resistant ability of the purse seine are strengthened. Through the specification and position design of spawning ponds and ellipsoidal grooves, the amount of the vortexes formed near the pile columns is large and the vortexes are small, so that a relatively quiet environment is formed in the aquaculture purse seine, an unexpected promoting effect is achieved to the growth of fish, and a certain decontamination effect is achieved.

Description

technical field [0001] The invention relates to large-scale marine aquaculture equipment, in particular to an elastically tied and fixed-connected shallow sea aquaculture seine net. Background technique [0002] The tide and wind and waves are the biggest safety factors affecting the purse seining system. Accidents of fish escaping from broken nets have occurred frequently, causing major economic losses to farmers. Optimizing the seine aquaculture system begins with the selection of net materials. Taking the pile-type seine aquaculture model as an example, the net materials can be selected from metal rigid nets and polyethylene flexible nets. Both have their own advantages and disadvantages. Based on the mechanical characteristics, the flexible mesh has better anti-wind and wave performance in theory. Both are still in their infancy, and many key technical issues remain to be resolved. The fixing method of nets and piles is an important factor affecting the safety of the s...

AI Technical Summary

Problems solved by technology

At present, nets and piles are directly tied to fix the net to transfer the wave and water loads of the net to the piles. In this way, the design requirements for the anti-drilling, tensile breaking and anti-tilting of the piles are relatively high, and the cost is economical. are also larger and prone to damage in extreme weather conditions
