Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a chain type floating and sinking box net.
Background
The net cage culture is an important part of ocean economy and has wide market and development potential. The net cage culture process does not need auxiliary resources, saves resources and has the characteristics of low investment and high return. The key factor for restricting deep sea cultivation lies in the wind and wave resistance of the net cage, and the solution of the problem can add assistance to the deep water development of the whole industry.
The net cage culture in the ocean faces the threat of wind waves, for example, the net cage floating on the sea surface can be destroyed under the typhoon condition, and the defect can be improved to a greater extent by two ways. The net cage can float and sink, and the net cage can effectively resist wind waves when the net cage sinks because the wave energy gradually drops from the water surface to the seabed; secondly, the original rigid structure is changed into a flexible structure, and the damage is reduced by using the soft-gram rigidity.
Disclosure of Invention
The invention aims to provide a chain type floating and sinking cage net, the cage net is driven by a flexible chain to be rotated to a deeper position below the sea surface to resist wind and wave, the internal design of the cage net can effectively accelerate the exchange speed of inner and outer water flows, various fishes can be cultured simultaneously, and the culture benefit of fishermen is improved.
The scheme adopted by the invention for realizing the purpose is as follows: the chain type floating and sinking box net comprises floaters, rolling type double chains and a frame, wherein an outer breeding net bag is arranged inside the frame, the four corners of the frame are fixedly connected with the rolling type double chains, the tail ends of the rolling type double chains are connected with anchoring blocks, and the tops of the rolling type double chains are connected with the floaters through connecting frames. The four right-angle sides of the external aquaculture net bag are fixedly connected with the rolling type chains, when the integral net cage needs to sink below the water surface, the wire coiling disc at the top of the net bag slowly winds the four extension ropes connected with the rolling type chains to shorten the action lengths of the four rolling type chains, thereby the whole net cage moves downwards to achieve the aim of resisting wind and waves, the bottom of the anchoring block is inserted with the anchor point to play the role of fixing the net cage, the upper end of the anchoring block is provided with a through hole, the rolling type double chains penetrate through the through holes, so that the chain can be fixed, the flexibility of the chain in operation can be effectively improved, the phenomenon of blockage of the chain in pulling and rolling can be avoided, the internal structure design of the net cage can be used for culturing various aquatic products, different culture areas are selected according to the sizes and habits of different aquatic products, so that the problem that the conventional aquaculture net cage cannot culture various aquatic products is solved, and the economic benefit of culture is remarkably improved.
Preferably, a pulley is sleeved on a connecting frame connected with the lower end of the floater, a rolling type double chain is hung on the pulley and connected with one end of an extension rope, the other end of the extension rope is connected with a winding roll, and the winding roll is positioned at the top of the outer breeding net bag.
