Problems solved by technology

[0004] In deep waters, the wind and waves are generally relatively large, especially in the typhoon-prone areas of the East my country Sea and the South China Sea. The impact of wind and waves on deep-water cage culture is particularly obvious. In order to ensure the safety of cultured organisms, deep-water cages must have reliable wind and wave resistance. Now In the prior art, most of the net cages have poor anti-wind and wave performance, and the operation is more complicated, the breeding cost is high, and the work efficiency is low

Embodiment 1

[0024] like Figure 1-5As shown, the deep water cage with pulley lifting mechanism includes cage 9, buoy 1, sink 11, sink lifting mechanism 3, the top of cage 9 is installed with sink lifting mechanism 3 near the middle position, sink lifting mechanism 3 The sinker 11 is suspended directly under the cage 9 by the rope 6, the buoys 1 are provided on both sides of the cage 9, the bottom of the cage 9 is connected with a bottom plate 14, the bottom plate 14 is provided with a number of permeable holes, and the permeable holes are provided with water permeable holes The net 17, the water-permeable hole is composed of a central water-permeable hole 15 and a number of peripheral water-permeable holes 13. The whole device is lifted and lowered by the cooperation of the sinker 11 and the buoy 1. When the cage 9 needs to sink, the sinker lifting mechanism 3 controls the sinker 11 through the rope 6, so that the sinker 11 is located directly below the cage 9 and downwards. Movement to ...

Embodiment 2

[0034] The deep-water cage with pulley lifting mechanism of the present invention is actually used: the whole device is lifted and lowered by the cooperation of the sinker 11 and the buoy 1. When the cage 9 needs to sink, the sinker lifting mechanism 3 controls the sinker through the rope 6. 11. Make the sink 11 located directly below the cage 9 and move downward to avoid the overturning phenomenon of the cage 9. As the water body continues to enter from the water hole 10, the sinking speed of the sink 11 is gradually accelerated, thereby accelerating the cage. 9. At the same time, the sinker 11 can be moved to the mooring device 5 by pulling the cable 8, thereby driving the whole device to move downward; when the cage 9 needs to float up, the sinker lifting mechanism 3 can be adjusted to move the sinker 11 upwards At the same time, the cable 8 can be loosened through the float 7 on the water surface. Under the combined action of the two, the sink 11 can move up smoothly and qu...

Embodiment 3

[0036] Two sets of different equipment were selected and placed in a certain sea area in Zhoushan to breed fish. The area of ​​​​the sea area was 800X700 square meters, the water depth was 10-20 m, the water temperature during the culture was 26-32 °C, and the feeding time was 6:00 and 12. :00, 18:00, the feeding amount is determined according to different stages, but it is necessary to ensure that the feeding amount of the two sets of equipment is the same. After 120 days of breeding, observe and compare the fish changes;

Abstract

The invention discloses an aquaculture device, in particular to a deep-water net cage with a pulley lifting mechanism, including a net cage, a buoy, a sinker, and a sinker lifting mechanism. The sub-lifting mechanism hangs the sinker directly under the net cage through ropes. There are buoys on both sides of the net cage. It consists of a central permeable hole and several peripheral permeable holes. The device has strong anti-wind and wave performance, is less affected by wind and waves, and can increase aquaculture production while ensuring the safety of aquatic products.

Description

technical field [0001] The invention relates to an aquaculture device, in particular to a deep-water cage with a pulley lifting mechanism. Background technique [0002] With the continuous increase of human demand for animal protein and the serious decline of the world's traditional fishery resources, the world fishery with marine fishing as the main body is gradually transforming into aquaculture fishery to meet human needs and promote the sustainable development of world fishery; in recent years , The rapid development of marine deep-water cages is in line with this change. [0003] Although my country's deep-water cage culture started late, its development speed is faster than that of foreign countries. Deep-water cage culture has developed extremely rapidly since the 1980s. The general development trend of marine aquaculture is from shallow seas to deep seas, from small-scale, extensive and extensive. The rise and development of large-scale wind-resistant deep-water cage...
