Single point mooring cage system with net fixing function

Abstract

The invention discloses a single point anchor type net cage system with a function of netting fixing. The single point anchor type net cage system comprises an anchor foundation, an anchor chain, a floating pipe frame, a netting and a sinker. The lower end surface of the floating pipe frame is provided with a tubular netting; the sinker is suspended at the lower end of the netting at intervals; a plurality of rows of sleeve tubes distributed vertically are arranged around the netting. The single point anchor type net cage system also comprises a component force frame. The component force frame is composed of a circular ring tube and a plurality of inclined tubes; the upper ends of the inclined tubes are uniformly and symmetrically welded below the outer wall of the circular ring tube; the lower ends of the inclined tubes are gathered to one point and provided with mooring rings in a welding mode. The anchor chain is composed of a first level anchor chain and a second anchor chain; one end of the first level anchor chain is moored on the anchor foundation, the other end is moored on a mooring ring frame of the component force frame; after the second anchor chains pass through the sleeve tubes, one end of the second anchor chains is moored on the floating pipe frame, the other end is moored on the circular ring tube of the component force frame. The single point anchor type net cage system with the function of netting fixing belongs to the single point mooring method, based on the fixing and distracting functions between the sleeve tubes and the second anchor chains, four walls of the netting do not gather together so as to maintain the breeding space.

Description

Technical field: [0001] The invention relates to a net cage for mariculture, and more specifically, to a single-point mooring net cage system with a net fixing function. Background technique: [0002] The sea area within the 20 m isobath in my country is about 16 million hectares, and the sea area within the 40 m isobath is about 50 million hectares. There is a huge space for the development of mariculture. Vigorously developing deep-water cage culture with a water depth of more than 20 m, obtaining resources from the ocean, expanding living space, developing "marine pastures" and establishing "sea granaries" are one of the new ways to solve the problem of food supply security in my country. [0003] The deep-water cage industry is one of the important innovative industries for my country's fishery to move towards a modern fishery. Aquaculture cages are generally composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system....

AI Technical Summary

Problems solved by technology

However, when changing the net clothes, cleaning the net clothes or pulling the net to collect fish, divers need to dive to the bottom to pull the sinker out of the water before collecting the net, or take out the support ring, which increases the labor time and thus increases the breeding cost. and low work efficiency
