The culture net cage has the following beneficial effects:
1. In the daily cultivation process, the water surface frame 4 is always on the sea surface, and the cultivation net cage is only operated when fishing operation, safety inspection or stormy waves are carried out; in the cultivation process, the operation ship is close to the water surface frame, i.e. the artificial bait casting or the automatic bait casting by adding bait is realized, the cultivation net cage does not need to be floated out of the sea for bait casting, the bait casting operation is safe and simple, namely, the cultivation net cage does not need to be frequently controlled to ascend and descend, the frequent movement of the cultivation net cage is avoided, and the growth and development of cultivation products are influenced; moreover, the movement of the connector 71 and the plurality of flexible floats 72 does not cause the work vessel to scrape the wave-resistant netting when the work vessel is approaching the farming net cage.
2. The outside of the wave-resistant net 3 can effectively help to expand the wave-resistant net 3 through the water surface frame 5, the connecting pieces 71 and the flexible floating balls 72, the cultivation space of the cultivation net cage is kept, the ocean current deformation resistance performance is good, the cultivation volume of the cultivation space is always kept, the cultivation space in the cultivation net cage is prevented from being impacted by larger ocean currents and ocean waves thereof, the living environment of the cultivation product is guaranteed, and meanwhile the cultivation space of the cultivation product is also increased.
3. The wave-resistant netting is located on the upper portion of the whole aquaculture net cage, so that the impact of sea waves on the aquaculture net cage can be better resisted, the connecting piece 71 and the plurality of flexible floating balls 72 can not directly resist the force generated by the sea waves when the sea waves impact, the impact of the sea waves on the aquaculture net cage can be absorbed and dispersed when the sea waves impact, the stress of the aquaculture net cage is effectively reduced, the aquaculture net cage is prevented from being damaged by typhoon and billows, typhoon prevention capability is strong, and the influence of ocean currents is small.
4. After the cultivation is completed, the water inlet and drainage mechanisms are controlled to be inflated and drained, so that the frame floats on the sea surface, the connecting zipper 6 on the wave-resistant netting is pulled open, the wave-resistant netting 3 and the water surface frame 4 are taken away, cultivation products are concentrated in the netting 2, and the fish collecting effect of the cultivation net cage is achieved.
5. The culture net cage is an upper-layer culture space and a lower-layer culture space, the upper layer is a culture space of a round table structure formed by the wave-resistant netting and the lower layer is a culture space of a cylindrical structure formed by the netting, so that the culture space of a culture product is ensured, and meanwhile, the wave-resistant netting is detachable and can be quickly detached and installed under the conditions of replacement and the like.
6. If the wind and the waves are encountered, the whole aquaculture net cage is lifted by controlling the air charging and discharging and the water charging and discharging of the air charging and discharging mechanism, so that the impact of the wind and the waves on the aquaculture net cage is avoided.
Therefore, the cultivation net cage has the advantages of large cultivation space, capability of effectively resisting stormy waves, no need of frequently operating the cultivation net cage in the cultivation process, capability of better ensuring the growth and development of cultivation products, high efficiency in cultivation, simplicity and convenience in management operation and wide application range in sea areas.
The operation method of the cultivation net cage specifically comprises the following steps:
Step one, sinking the netting 2: conveying and lowering the cultivation net cage according to claim 5 into a cultivation sea area, namely binding the outer side of the frame 1 on a floating ball 82 floating on the sea surface through an anchor rope 81 on the cultivation sea area, binding a anchoring block 83 sinking into the sea bottom on the anchor rope 81, and then carrying out air exhaust and water inlet operation through an air inlet and exhaust mechanism to enable the frame of the cultivation net cage to float on the sea surface, wherein the netting is erected on the sea bottom in a fixed state;
Step two, installing a wave-resistant netting 3: a worker stands on the top surface of the frame 4 in the first step, puts the breeding products into the breeding space of the netting 2 from the top surface opening of the netting 2, stacks the wave-resistant netting 3 on the frame 4, connects the lower end of the wave-resistant netting 3 with the upper end of the netting 2 through a connecting zipper 6, completes the installation of the wave-resistant netting 3, and finally leaves the frame 4;
Step three, culturing and sinking: the frame 4 in the second step is exhausted and water is fed by utilizing a water and air exhausting mechanism, so that the frame 4 is completely sunk in the sea, the water surface frame 5 floats on the sea surface, and the cultured products can be cultured and grow in the culture space and the hollow space of the wave-resistant netting 3;
Step four, bait is added: the worker adds bait into the input end of the automatic bait casting machine on the water surface frame 5 on the operation ship, and then automatically adds the bait into the culture space through the bait casting port by using the automatic bait casting machine; so that the bait is not required to be frequently lifted and lowered in the cultivation process, the cultivation products are not disturbed,
Step five: fishing: the water surface frame and the frame are lifted upwards through the water inlet and outlet air mechanism, the water inlet and outlet air mechanism is stopped after the frame floats on the sea surface, the wave-resistant netting 3 can keep an upright state when the water surface is lifted out, a worker climbs on the frame, the connecting zipper 6 is pulled open, the wave-resistant netting 3 and the water surface frame 5 are detached from the netting 1, the netting 1 is in an open state, and the fishing work can be started.
The operation method of the culture net cage has the advantages that the method has the same advantages as the culture net cage, meanwhile, when the wind and wave currents are large, the length of the anchor rope 81 can be adjusted, the floating ball 82 floats on the sea surface, the culture net cage sinks to a deeper sea area, namely, the large-range lifting of the whole culture net cage is controlled by adjusting the length of the anchor rope 81, the wind and wave can be effectively resisted, the damage of the culture net cage and the damage of culture products can not be caused in the weather of strong wind and wave, when the wind and wave is small, the small-range lifting of the culture net cage can be realized by controlling the water and air drainage mechanism, the combination of the small-range lifting and the large-range lifting of the culture net cage can be realized, the wind and wave current resistance is strong, and the method is suitable for the sea area; when the fishing work is carried out, the wave-resistant netting can be fished after being disassembled, the operation is simple and convenient, the operation efficiency is high, and the fishing net is more suitable for popularization and application in coastal or even deep sea cultivation.
The form of the present invention is not limited to the illustrations and examples, and any person who performs a similar idea of the present invention should be regarded as not departing from the scope of the patent of the invention.
