Combined module type large purse seine for deep open sea breeding
Technical Field
The invention relates to the technical field of deep and open sea culture equipment, in particular to a combined modular large purse seine for deep and open sea culture.
Background
The current common deep and open sea purse seine technology mainly comprises two types, namely a floating rope type purse seine and a tubular pile type purse seine. The floating rope type purse seine has no bottom net, so that the cultured objects escape from the bottom of the protective net and become a restriction factor for the wide application of the raised objects. The tubular pile type purse seine is made of steel pipe piles, the steel pipe piles are divided into an inner ring and an outer ring, and then the steel pipe piles are coated with a common protective net. The length of the steel pipe pile is about 24 meters generally, the length of the domestic steel pipe is only 12 meters, so welding is needed, the welding part becomes a weak link of the pipe pile, the pipe pile has the risk of breaking under the impact of wind waves, and the pipe pile needs special equipment during construction, so the construction difficulty is high, and the cost is high. Therefore, a new type of large seine which is convenient for construction is needed.
