Embodiment 1

[0019] combine figure 1 , The free-diving gravity type net cage of the present invention comprises upper frame, lower frame, net clothing and anchorage. combine figure 2 and image 3 , the upper frame includes an upper frame buoyancy pipe 1, a handrail pipe 2 and a connecting piece 3 between the two, an annular pontoon 4 is arranged between the two upper frame buoyancy pipes, a ballast water pump 5 is installed on the annular pontoon, and a circular operation is arranged in the center of the upper frame. zone 6;

[0020] The nets include top nets 7 and middle nets 8, which are respectively located in the upper and lower regions of the buoyancy tube; the first connecting rope 9 connects the upper frame buoyancy tube and the lower frame buoyancy tube 10, and its other end is fixed with a plurality of small sinkers 11 , the second connecting rope 12 connects the lower frame buoyancy tube 10 and the large sinker 13;

[0021] One end of the mooring rope 14 is connected to the ...

Embodiment 2

[0023] The second embodiment of the present invention is based on the first embodiment: as Figure 1-3 As shown, in the actual use of a free-diving gravity cage, the cage is installed and put into the breeding sea area to breed aquatic products. When bad weather such as typhoon occurs, the waves will hit the cage. cause havoc. At this time, the ballast water pump 5 pumps the ballast water into the buoyancy tube 1 of the upper frame, and the hoisting equipment located in the circular operation area 6 will tighten the anchor chain rope 14, so that the net cage slowly descends while maintaining the tension of the anchor chain rope. Tight, to ensure the vertical diving of the net cage, and at the same time, the speed of the diving can be accelerated by adding counterweights in the large sinker 13. When the net cage reaches the appropriate water depth, the number of counterweights and ballast water can be adjusted to keep the net at the same time. Tension under water makes the cag...

Abstract

The invention provides a gravity type net cage capable of achieving free submerging and descending. The gravity type net cage comprises an upper frame, a lower frame, a net and an anchor; the upper frame comprises upper frame buoyancy pipes and armrest pipes, the upper frame buoyancy pipes are connected with the armrest pipes through connecting pieces, an annular floating bridge is arranged between the two upper frame buoyancy pipes, and a ballast water pump is arranged on the annular floating bridge; a circular operation area is arranged in the center of the upper frame, hoisting equipment isarranged on the circular operation area, the lower frame comprises two lower frame buoyancy pipes with different diameters, the lower frame buoyancy pipe at the outer side and the upper frame buoyancy pipes are connected with a small sinker through a first connecting rope, and the lower frame buoyancy pipe at the inner side is connected with a large sinker through a second connecting rope. Compared with a traditional gravity type net cage, the net cage can work for a long time in an open sea area, when typhoon comes, the net cage can be submerged below the water surface through submerged equipment, and damage of severe weather such as the typhoon to the net cage is avoided.

Description

technical field [0001] The invention relates to a gravity net cage, in particular to a gravity net cage capable of diving freely, and belongs to the field of breeding net cages. Background technique [0002] Cages are widely used as a new type of high-efficiency aquaculture equipment. However, traditional cages have a single structure, simple functions, poor wind and wave resistance, and are prone to damage to the cage structure. Contents of the invention [0003] The purpose of the present invention is in order to provide a kind of free-diving gravity net cage which can be operated in open sea area for a long time, and can freely dive below the water surface to avoid the destruction of the net cage when disasters such as typhoons strike. [0004] The purpose of the present invention is achieved like this: [0005] A free-diving gravity net cage includes an upper frame, a lower frame, a net and anchorage, the upper frame includes an upper frame buoyancy tube and a handrai...
