Anti-storm deep sea aquaculture net cage

Abstract

The invention discloses an anti-storm deep sea aquaculture net cage, and relates to the technical field of aquaculture net cages. The anti-storm deep sea aquaculture net cage comprises frame assemblies and a spherical culture net cage, wherein the spherical culture net cage is rotationally matched with the frame assemblies, the frame assemblies are fixedly connected through fastening bolts; the spherical culture net cage comprises an annular frame plate, an upper arc-shaped top plate and a lower arc-shaped top plate, the circumferential side surfaces of the upper arc-shaped top plate and the lower arc-shaped top plate are both fixedly connected with rotating shafts, and rotating sleeves are rotationally matched with the rotating shafts. According to the anti-storm deep sea aquaculture net cage, all the frame assemblies are fixedly connected together through the fastening bolts, buoyancy is provided for the whole device through arrangement of an annular floating ball and a floating plate, the device is fixed through a mooring rope, and the stability of the whole device is improved; fry are cultured in the spherical culture net cage, the spherical culture net cage is stressed to rotate in an annular plate when large stormy waves are encountered, most of force is offset, resistance borne by the frame assemblies is effectively reduced, and the situation that the device is subjected to large resistance at the same time, and the structure of the device is damaged is avoided.

Description

technical field [0001] The invention belongs to the technical field of aquaculture net cages, in particular to a wind and wave resistant deep sea aquaculture net cage. Background technique [0002] With the continuous development of the aquaculture industry, cage culture has gradually become an important way of aquaculture. Cage culture is a high-tech breeding project developed in recent years. It uses mesh to assemble a certain shape of the box, set it in a larger water body, and exchange the water inside and outside the cage through the mesh to make the inside of the cage Form a living water environment suitable for the life of aquatic animals, with the characteristics of high yield, high benefit and high investment. There are many structures and installations of net cages. The actual selection should be based on the principles of not escaping fish, durable, labor-saving and material-saving, convenient for water exchange, and convenient management. [0003] However, trad...

Problems solved by technology

[0005] Although this anti-wave deep-sea culture cage adopts the sinking cage method, it can effectively reduce the impact of wind and waves on the cage. The net cover and net clothing are in a zipper structure, which can enhance the stability of the cage, and it is still the same as the traditional culture cage. Similarly, the aquaculture cages belong to a rectangular frame structure. For the convenience of fishing, the rectangular frame-shaped aquaculture cages are set with an opening on one side, and the aquaculture cages and the frame structure are integrated. When they are beaten by large waves, they are easily deformed or even damaged. , once the breeding net cage is damaged, the cultured fish will run away, causing greater economic losses
