Abstract

The invention discloses a double-column flexible aquaculture purse seine in a shallow sea, and belongs to the technical field of purse seine aquaculture devices. The purse seine comprises column pilesconnected with a seabed and a main net connected with the column piles, the top ends of the two longitudinal column piles are fixed by cross bars, the column piles are symmetrically arranged at bothsides of the main net, the section of the main net is X-shaped, the junctions of the main net are connected by steel ropes, and the upper part of the main net is fixed with the upper ends of the column piles through lassos; the lower part of the main net is fixed with the lower ends of the column piles through lassos and buried into the seabed, the column piles are fixed with the seabed of the shallow sea through pile bases, the column piles are fixed with the pile bases through fixing devices, and a double-layer net with netting large in mesh size is arranged on the portion, between a high tide place and a low tide, of the main net. According to the technical scheme, the situation can be avoided that netting is damaged because the purse seine is stacked and entwined at different tide places; the stability and the capability for resisting wind and waves of the whole structure of the aquaculture purse seine can be improved; the purse seine has the advantages of being applicable to large-scale purse seine engineering in shallow seas, simple in construction, economical, environmentally friendly and high in universality and sustainability.

Description

technical field

[0001] The invention belongs to the technical field of seine aquaculture devices, in particular to a double-column flexible shallow sea aquaculture seine. Background technique

[0002] my country's seawater cage culture started in the 1970s. In recent years, the scale of cage culture has developed rapidly. The shallow sea seine culture project is a typical marine facility culture model. The piles are directly tied and vertically fixed, which requires high design requirements for pile resistance, tensile fracture resistance and tilt resistance, and the economic cost is also high, and it is easy to cause damage in extreme weather conditions, while the suspension type and The floating rope seine type is more suitable for small and medium-sized aquaculture sea areas, and it is difficult to apply to large-scale and large-scale aquaculture projects.
