Embodiment 1

[0024] Such as Figure 1-7 Shown, the three-dimensional cage of gossip spider web type comprises frame 1, net clothes 2, isolation net 16, and frame 1 surface is connected with transverse connecting rod 9 and longitudinal connecting rod 10, and transverse connecting rod 9 and longitudinal connecting rod 10 are interlacedly arranged, and framework 1 is provided with a netting 2 inside, a connecting cable 3 is connected to the bottom of the frame 1, the end of the connecting cable 3 is connected to a free suspension weight body 4, the lower surface of the free suspension weight body 4 is connected to a self-mooring chain 5, and the end of the self-mooring chain 5 is connected to a self-mooring chain 5. Parking weight 6. The net cage is designed as a gossip spider web. In terms of structure, the quantitative force analysis of the spider web structure can prove that the structure is very stable, avoiding the reduction of the volume ratio, which will cause the aquatic products to b...

Embodiment 2

[0032] Such as Figure 1-7 As shown, in the actual use of the gossip spider web type three-dimensional cage, the bottom of the frame 1 is connected to the free suspension weight 4, and the lower surface of the free suspension weight 4 is connected to the self-mooring ballast 6 through the self-mooring chain 5, and single mooring is adopted. In this way, when the mooring cage is subjected to an external force and leaves its original position, it will rotate freely at all angles, and drift along the tide, so as to achieve the minimum force, and the sliding sleeve on the longitudinal connecting rod 10 will be driven by the impact of the water flow on the cage. 11 Slide up and down on the longitudinal connecting rod 10 to clean the netting 2, accelerate the water flow exchange speed inside and outside the netting 2, improve the water quality condition in the net cage, and the isolation net 16 in the netting 2 is connected to the netting 2 To support, the top of the isolation net 1...

Abstract

The invention discloses an eight-diagram spider web type three-dimensional cage, and belongs to the technical field of aquaculture. The eight-diagram spider web type three-dimensional cage comprisesa frame, a net coat and a separating net, wherein the surface of the frame is connected with horizontal connecting rods and longitudinal connecting rods, the horizontal connecting rods are interlacedwith the longitudinal connecting rods, and the frame is internally provided with the net coat, a connecting cable is connected to the bottom of the frame, the tail end of the connecting cable is connected with a free hanging weight body, the lower surface of the free hanging heavy body is connected with a self-mooring chain, and the tail end of the self-mooring chain is connected with a self-mooring weight. The designed cage has high structural stability, can effectively avoid the problem of low volume ratio, can also automatically remove microorganisms and dirt adhered to the surface of the net coat, makes a breeding environment closer to nature, and improves the quality of cultured aquatic products.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a gossip spider web type three-dimensional cage. Background technique [0002] Cage aquaculture is an important part of the marine economy and has a broad market and development potential. The cage culture process does not require auxiliary resources, saves resources, and has the characteristics of low investment and high return. The key factor restricting deep-sea aquaculture is the anti-wind and wave ability of cages. Solving this problem will help the entire industry to advance to deep water. [0003] Cage culture in the ocean is affected by wind, waves and currents. Under the effect of tidal currents, the shape surrounded by the flexible net clothing of the box is easily deformed, resulting in a decrease in the volume ratio and causing the fish to be squeezed to death. Therefore, the use of frame structure for the overall cabinet can avoid the reduction of v...
