The structure of the embodiment of the invention as shown in Figure 1, it comprises scaffold a, etting b and mooring system c, scaffold a is annulus or the polygon circle that is formed sealing by identical two-layer hollow pipe, the blank area of upper strata hollow pipe a1 is equipped with "T"-shaped threeway connecting piece a3, inverse-T-shaped threeway connecting piece a4 is installed in lower floor hollow pipe a2 relevant position, the upper strata threeway connecting piece a3 threeway connecting piece a4 of lower floor connects by standpipe a5, one of upper strata threeway connecting piece a3 connects air inlet-outlet pipe a6, one of threeway connecting piece a4 of lower floor connects intake-discharge pipe a7, and the free end of air inlet-outlet pipe a6 and intake-discharge pipe a7 is provided with valve a8, a9.Hollow pipe a1, a2, standpipe a5, threeway connecting piece all are working of plastics, and material is PE-112, its density accomplishes＞and 10
3Kg/m
3, guarantee can sink under water after water is filled in its inside, so just need not regulate proportion by means of filler, weight etc.Between the hollow pipe and and standpipe between by connecting piece socket and sweat soldering.
Scaffold a border connects the etting b that is made up of go in ring net b1, spacer screen b2, and go in ring net b1, spacer screen b2 are linked together the circle that bracing ring b3 surrounds less than scaffold a hollow pipe by bracing ring b3.Ring network b1 twines to connect and is fixed on the circle pipe a1 of upper strata, and its neck periphery is positioned at the inside of the circle pipe a2 of lower floor.
During actual the use, when no stormy waves or stormy waves were smaller, scaffold a swam on the water surface, fish for like this, feeding is all more convenient, this moment, intake and exhaust valve a8 and water-inflow and drain valve door a9 closed, and the gravity of whole net cage and buoyancy equal and opposite in direction, direction are opposite, are in poised state.When typhoon comes interim, open intake and exhaust valve a8 and water-inflow and drain valve door a9, water flows into the hollow pipe of scaffold automatically from the water-inflow and drain valve door a9 of the hollow pipe a2 of lower floor, in the standpipe, air is discharged from intake and exhaust valve a8 simultaneously, this moment, the gravity and the balance between the buoyancy of net cage were broken, because entering of water, the gravity of net cage increases, net cage begins to sinking, and the water-immersed volume of scaffold a increases gradually, and buoyancy also increases gradually, because the volume of the water that the size of buoyancy only arranges with object is directly proportional, its buoyancy was certain when net cage immersed in the water fully, and when the gravity of net cage equated with the maximum buoyancy of net cage, net cage reached balance again; At this moment, scaffold arrives below the water surface fully, has avoided the impact of stormy waves.For preventing the fish escape, can on the circle pipe, one deck cover net be set, itself and belt net, spacer screen surround the closed area.Can be by the height of how much controlling the relative horizontal plane of scaffold a of water in the circle pipe of scaffold a.The free-ended height of air inlet-outlet pipe and intake-discharge pipe can be determined according to actual conditions.The shape of the circle pipe of scaffold can surround circle, regular hexagon, dodecagon etc.
