The main frame connection in.

Compared with the prior art, the utility model has the following advantages: 1. Because the main frame of the net cage can sink and float to a certain extent by controlling the water inflow or inflation in the floating pipe, the sinking depth can be adjusted. Depending on the underwater depth of the main rope of the Tian-shaped structure anchored by buoys and iron anchors, the entire cage can be sunk to realize normal farming under harsh sea conditions and avoid typhoons, storms, and wind and waves. Destruction of cages. 2. Seawater cage culture can be pushed from the coast and the inner bay to the open sea, expanding new breeding space, and can also greatly expand the breeding scale, and can expand the breeding water area to the sea area with a water depth of 100m. 3. Breeding in an open sea environment has the characteristics of stable environment, good water exchange, less disease, good quality of farmed fish, and high benefit; at the same time, due to the effect of water flow, it also solves its own breeding pollution problem, which is beneficial to improve near-term Seawater environments in coastal areas and harbors.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, this embodiment includes a main frame, a mesh bag and a buoy mooring device for fixing the main frame and the mesh bag in water. The main frame 1 is composed of inner and outer circular floating tubes 1a and 1b of different diameters. The inner and outer circular floating tubes are high-density polyethylene round tubes welded by heat sealing; the inner and outer circular floating tubes are connected by an I-shaped connecting frame 3 Fixedly connected on the same level, each round floating tube is equipped with two inflation valves 4 and two water inlet valves 5 that control the rise and fall of the floating tube, and the installation positions of the inflation valve 4 and water inlet valve 5 on the round float Symmetrical; when the air inlet valve and the water inlet valve are opened at the same time to allow the floating pipe to enter water from the water inlet valve, as the weight of the floating pipe increases, the net cage can sink to a predetermined depth; when the air inlet valve is filled with compressed air At this time, the water in the floating pipe is discharged from the water inlet valve, so that the net cage rises to the water surface. Two inflation valves and two water inlet valves in each round floating tube correspond to form two independent pipelines; this enables the main frame to rise and fall smoothly in seawater; the main frame 1 is also equipped with a block frame 2 and a net cover, Block frame 2 is fixed on the inner floating pipe 1a of main frame, and net cover is enclosed within on block frame 2, when can prevent that net cage floats on the sea surface or the fish that is cultured in lifting process escapes from net cage.

The mesh bag is composed of a circular truncated mesh 6, a side force rail 7 and a sinker 8. The mesh 6 is woven from ultra-high molecular polyethylene or polyethylene material, and the top of the mesh is tied on the sides around the mesh. The force grid 7 is connected to the inner floating pipe 1a of the main frame, and the sinker 8 is connected to the bottom of the side force grid 7; thereby ensuring that the weaving net maintains a normal circular truncated state in water.

The buoy mooring device includes a main rope 9, a connecting ring 10, a lifting and positioning rope 11, a main buoy 12, an auxiliary buoy 13 and an iron anchor 14. The main rope 9 is braided into a grid structure, and the connecting rings 10 are arranged at four intersections. Auxiliary buoy 13 is connected on the connecting ring 10 of intersection, and each main rope of four intersections all extends outward several meters, connects main buoy 12 through a rope, and main rope continues to extend downwards and connects anchor chain, and then by anchor The chain is connected to the iron anchor 14, so that the main rope 9 braided into a grid structure is fixed underwater by the main buoy 12, the auxiliary buoy 13 and the iron anchor 14; Rope 11, the hoisting and positioning rope 11 is connected with the main frame 1 placed in the grid. The main rope is also woven into a Japanese grid or matt structure, and its connection relationship with the above-mentioned other components is the same as the grid structure, and a main frame and a net bag are placed in each grid, so that the breeding scale can be enlarged.

The concrete operation when the utility model settles is as follows: first connect one end of the inflation hose (the length of the hose depends on the settlement depth) to the inflation valve of the main frame, and connect the other end to the air compressor air storage cylinder on the working boat. At the same time, open the inflation valve and the bypass valve on the air compressor; then open the water inlet valve of the main frame to let sea water enter the floating pipe of the main frame. The air in the pipe is automatically discharged by the bypass valve at the air outlet of the air storage tank. When sinking to a predetermined depth, it will be fixed in the grid woven by the main rope in the buoy mooring device; at this time, the inflation pipe interface connected to the air outlet of the air compressor air storage tank can be removed to complete the settlement operation.

The specific operation of the utility model when floating is as follows: first connect the inflatable pipe to the air outlet of the air compressor air storage tank on the working boat, close the bypass valve; then open the air compressor, let the air enter the floating pipe of the main The water is discharged from the water inlet valve. Adjust the air volume to make the inner and outer floating pipes float up as balanced as possible. After the main frame floats to the water surface, close the air outlet valve of the air storage tank of the air compressor so that the air pressure of the air storage tank reaches 0.4MPa, and then turn on the air compressor. The air outlet valve of the air storage tank allows all the water in the floating pipe of the main frame to be discharged through the pressure air flow, repeat several times until the water is completely drained, then close the water inlet valve, remove the inflation pipe of the inflation valve and close the inflation valve to complete the flotation operate.
