Description

Eight diagrams spider net type stereo net cage
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to an eight diagrams cobweb type three-dimensional net cage.
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.
In the ocean, the net cage culture faces the influence of wind, wave and current, and under the action of tide, the shape surrounded by the flexible net of the cage body is easy to deform, so that the volume ratio is reduced, and the fishes die by extrusion. Therefore, the integral box body adopts a frame structure, so that the reduction of the volume ratio can be avoided. In addition, under the condition of a multi-mooring mode, due to the fact that the incoming direction of wind wave flow is unstable, stress on each mooring point is unbalanced, the force of some mooring positions is insufficient, and the large mooring force does not need to be given by some mooring positions.
Disclosure of Invention
The invention aims to provide the eight diagrams spider net type three-dimensional net cage which has strong structural stability, can effectively avoid the problem of low volume ratio, can automatically remove microorganisms and dirt adhered to the surface of a net, enables the culture environment to be closer to the nature and improves the quality of cultured aquatic products.
The scheme adopted by the invention for realizing the purpose is as follows: the eight diagrams spider-web type three-dimensional net cage comprises a frame, a netting and an isolation net, wherein the surface of the frame is connected with transverse connecting rods and longitudinal connecting rods, the transverse connecting rods and the longitudinal connecting rods are arranged in a staggered mode, the netting is arranged inside the frame, the bottom of the frame is connected with a connecting cable, the tail end of the connecting cable is connected with a free suspended weight body, the lower surface of the free suspended weight 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 net cage is designed into a eight diagrams cobweb type, and the quantitative stress analysis of the cobweb structure can prove that the structure is very stable, so that the reduction of the volume ratio is avoided, and the cultured aquatic products are extruded to die. The net cage is basically symmetrical and is stressed uniformly. The mooring net cage is connected with the seabed by a connecting cable at the bottom central point by adopting a single mooring mode, when the mooring net cage is away from the original position under the action of external force, the mooring net cage can rotate freely in all angles to follow tide to drift, so that the stress is minimum, the exchange of water bodies inside and outside the net cage can be accelerated, the bait and excrement in the net cage can be discharged out of the net cage as soon as possible, and the normal growth of aquatic products can be guaranteed.
Preferably, the frame is provided with symmetrical air bags on the outer side, the air bags are in strip shapes and extend to the bottom surface of the frame along the outer surface of the frame, and the top of the frame is provided with an air inlet hole. The gasbag in the frame outside can play corresponding effect to the ups and downs of box with a net, and the box with a net can corresponding come up when being full of gas in the gasbag, and can be comparatively easy according to coming of trend to drifting, alleviate the weight of box with a net in aqueous when still being favorable to catching, it is more high-efficient when catching, the box with a net can sink a bit after giving out the inside gas of gasbag, play unrestrained effect of anti-wind.
As preferred, the cover is equipped with the sliding sleeve on the longitudinal tie rod, is equipped with the ball between sliding sleeve and the longitudinal tie rod, is connected with the telescopic link between the adjacent sliding sleeve, and the telescopic link surface is connected with the brush, and the telescopic link is equipped with the second bearing with the junction of sliding sleeve. This setting makes the sliding sleeve on the longitudinal tie pole slide from top to bottom through the impact of rivers to the box with a net, clear brush the etting, under the normal condition, telescopic link between sliding sleeve and the sliding sleeve is in quiescent condition, when rivers strike to the sliding sleeve, the sliding sleeve passes through the ball and can upwards the drunkenness, also can drive the telescopic link motion simultaneously, the surperficial brush of gliding in-process telescopic link can contact with the etting, microorganism and the filth thoroughly cleaning with etting surface adhesion, avoid the etting to steep the jam that leads to the etting mesh in aqueous for a long time, the inside and outside rivers exchange speed of etting has accelerated, the quality of water condition has been improved in the box with the net, it takes place and spread to have reduced the fish disease.
Preferably, 3 layers of separation nets are arranged in the netting, the middle parts of the separation nets are provided with circulation holes, and the mesh size of the separation nets is smaller than that of the netting. The isolation net is arranged in the netting, so that the net cage can be divided into a plurality of culture spaces, the culture density of aquatic products is reduced, the growth of cultured organisms is facilitated, the culture yield is improved, the circulation holes formed in the middle of the isolation net can enable the aquatic products to shuttle in the netting, and the aquatic products are prevented from being accumulated at the bottom of the netting.
Preferably, the thickness of the isolation net is 10cm-15cm, at least 2 mounting holes are formed in the isolation net, and first bearings are embedded in the mounting holes. The separation net can play an effective supporting role to the netting within the thickness range, and the bearing in the mounting hole is used for inserting the cross, so that the effect of the internal components of the net cage is maximized.
Preferably, a symmetrical cross is arranged above the isolation net, a ring is arranged on the surface of the cross, an insertion rod is connected to the bottom of the cross and inserted into the first bearing, and the first bearing is installed in the isolation net. The separation net top is provided with the cross, and the ring on ten support surfaces can supply the aquatic products of breed to perch, shuttle back and forth, has increased the activity of aquaculture, and the cross still can be rotatory by oneself around first bearing under the effect of rivers for the flow of water in the netting avoids bait, faecal deposit in the netting, makes the aquaculture environment be close to nature more, is favorable to aquatic products to grow.
Preferably, the circular ring is provided with a plurality of fish inlets, the inside of the circular ring is annularly provided with the net bag, and the net bag is filled with bait. Aquatic products from advancing in the fish mouth trip income ring, with the intra-annular net bag extrusion contact of ring, bait in the net bag can scatter to the ring in supply the aquatic products of breed to eat, and the smell through bait can attract more aquatic products to swim to the ring in and carry out the ingestion to food simultaneously, still can reach the effect of feeding.
Compared with the prior art, the invention has the beneficial effects that: the integral three-dimensional frame structure is designed, so that the reduction of the volume rate is avoided; in addition, a single-point mooring mode is adopted, only one point needs to be well moored, drifting is carried out in compliance with tide, the sliding sleeve on the longitudinal connecting rod drives the telescopic rod to clean the netting through impact of the tide, blocking of netting meshes caused by long-time soaking of the netting in water is avoided, water exchange speed inside and outside the netting is accelerated, water quality conditions in the net cage are improved, fish diseases are reduced, deposition of bait and excrement in the netting is avoided due to the arrangement of the isolation net and the cross frame in the netting, the breeding environment is enabled to be close to the nature, and aquatic product growth is facilitated.
