Problems solved by technology

With the continuous change of my country's national conditions and the rapid development of deep-water cage aquaculture, some problems have also emerged. At present, the performance of cage equipment against deep sea waves still needs to be further improved to provide a safe external environment for supporting facilities. These factors directly Restricted the rapid development of deep water cages

Embodiment 1

[0045] Such as figure 2 As shown, the first embodiment of the present invention is based on the above-mentioned inventive concepts, and adopts the following specific schemes for the frame system 1:

[0046] Frame system 1 is also provided with front frame edge 14 and rear frame edge 15; left wing frame part 11 is made up of left wing front side frame edge 111, left wing rear side frame edge 112 and left wing outer frame edge 113, and left wing front side frame edge 111 is The front edge 11a of the left wing frame member 11, the left outer side frame edge 113 is connected between the outer end of the left wing front side frame edge 111 and the outer end of the left wing rear side frame edge 112, and the left wing front side frame edge 111, the left wing rear side frame The side 112 and the left-wing outer frame edge 113 are arranged in a parallelogram, that is, the left-wing front side frame edge 111 is parallel to the left-wing rear side frame edge 112; frame edge 123, the r...

Embodiment 2

[0048] Such as image 3 with Figure 4 As shown, the second embodiment of the present invention is based on the above-mentioned inventive concepts, and adopts the following specific schemes for the frame system 1:

[0049]The frame system 1 is also provided with a main frame 13, which is a closed frame composed of an elliptical arc front frame 131, a left frame edge 132, a right frame edge 133 and a semicircular arc rear frame 134, wherein the ellipse The arc-shaped front frame 131 protrudes forward, the semi-circular arc-shaped rear frame 134 protrudes backward, and the left frame edge 132 is connected between the left end of the elliptical arc-shaped front frame 131 and the left end of the semi-circular arc-shaped rear frame 134 , the right frame edge 133 is connected between the right end of the elliptical arc-shaped front frame member 131 and the right end of the semicircular arc-shaped rear frame member 134; At the middle position of the right frame edge 133 . Thereby,...

Embodiment 3

[0053] like Figure 5 As shown, the third embodiment of the present invention is based on the above-mentioned inventive concepts, and adopts the following specific schemes for the frame system 1:

[0054] The frame system 1 of the third embodiment is basically the same as that of the second embodiment, and their difference is that in the third embodiment, according to the direction from the front end to the rear end of the frame system 1, the left frame side 132 and the right frame side 133 are all from the frame The outer side of the system 1 extends obliquely toward the inner side; thus, the water resistance experienced by the frame system 1 along the direction of the axis of symmetry 1 b can be further reduced.

Abstract

The invention discloses a double-wing deep-water net cage suitable for single point mooring. The net cage is provided with a frame system and a net, wherein the frame system floats on the sea surface,and is provided with a mooring point for connecting a single-point mooring system, and the net is hung on the frame system; the frame system is of an axisymmetric frame structure, and the mooring point is located on the symmetry axis of the frame system and at the forefront of the frame system; and the frame system is provided with a left wing frame piece and a right wing frame piece which are arranged symmetrically along the symmetry axis, the front edge of the left wing frame piece and the front edge of the right wing frame piece are inclined straight edges inclined to the symmetry axis, and the inclined straight edges incline and extend from the inside to the outside of the frame system according to a direction from the front end to the rear end of the frame system; and angles betweenthe inclined straight edges and the symmetry axis are 30-60 degrees. The net cage has the advantages of strong incident flow stability and strong wave resistance, high rigidity of the whole frame system and good rotation stability when the direction of water flow changes.

Description

technical field [0001] The invention relates to a double-wing type deep-water net cage suitable for single-point mooring. Background technique [0002] The deep-water anti-wind and wave cage culture technology effectively expands the breeding sea area, reduces the pressure on the near-shore environment and resource allocation, improves the breeding environment conditions, improves the quality of aquatic products, and effectively reduces the harm caused by the occurrence and spread of fish diseases , reducing the cost of breeding, greatly increasing the benefits of farming, and the deep-water anti-wave cages are located in wide breeding waters with smooth water flow, and the breeding operations have little impact on the water environment. [0003] Metal truss-type deep-water anti-wind and wave cages have a wider breeding space, better water quality conditions, and less pollution. At the same time, the metal truss-type deep-water anti-wind and wave cage can adapt to stronger ...
