Combined modular type large purse seine for deep and distant sea aquaculture

Abstract

The invention discloses a combined modular type large purse seine for deep and distant sea aquaculture. The boundary of the large purse seine comprises a plurality of purse seine modules which are evenly arranged, wherein each purse seine module comprises a pile foundation used for fixing, each pile foundation comprises a bottom beam frame, a plurality of fixing piles are arranged below each bottom beam frame, and a purse seine frame for blocking is arranged above each bottom beam frame; and an inner boundary frame is arranged on the inner edge of each purse seine frame, an outer boundary frame is arranged on the outer edge of the purse seine frame, a connecting frame is arranged on each of the left side and the right side of the purse seine frame, the connecting frames are connected withthe inner boundary frame and the outer boundary frame, and a protective net is arranged between the inner boundary frame and the outer boundary frame. The combined modular type large purse seine for deep and distant sea aquaculture adopts a modular assembly structure and the construction is convenient; and with adoption of the inclined protective nets, impact of ocean current stormy waves on the purse seine is effectively reduced, strength of the purse seine is improved, and service life of the purse seine is prolonged.

Description

technical field [0001] The invention relates to the technical field of deep-sea aquaculture equipment, in particular to a combined modular large-scale purse seine for deep-sea aquaculture. Background technique [0002] At present, the common deep sea seine technology is mainly two kinds of floating rope seine and pipe pile seine. The floating rope seine has no bottom net, so the breeding objects escape from the bottom of the protective net, which has become a restrictive factor for its wide application. The pipe pile fence is made of steel pipe piles. The steel pipe piles are divided into inner and outer circles, and then the steel pipe piles are covered with ordinary protective nets. The length of the steel pipe pile is generally about 24 meters, and the domestic steel pipe length is only 12 meters, so it needs to be welded, and the welded part becomes the weak link of the pipe pile, which has the risk of breaking under the impact of wind and waves, and the pipe pile needs...
