The explanation of accompanying drawing drawing:

1 inner ring pipe, 2 outer race tube, 3 balance pipes, 4 threeway connectors, 5 supports, 6 railings, 7 water inlets, 8 damping sheets, 9 mass, 10 water and gas conduits, 11 holes, 12 air inlet-outlet pipes, 13 intake-discharge pipes, 14 ends, weighed down, 15 chains.

Provide embodiment below in conjunction with accompanying drawing, utility model is at length explained.

With reference to figure 1-Fig. 8, each parts all can adopt the PE material to make, the two ends of inner ring pipe 1 are made into semi-enclosed structure, less water inlet 7 is left in the bottom, several damping sheets 8 are set (generally speaking in outer race tube 2, as if 6 meters of pipe ranges, establishing 2 damping sheets then gets final product), (mass 9 can use the silt particle concrete to fill to fill mass 9 in balance pipe 3, also can use metal making such as lead, but relative cost is higher), at inner ring pipe 1, outer race tube 2, preset out several holes 11 on the tube wall of balance pipe 3, respectively with inner ring pipe 1,

outer race tube

2,3 one couple together of balance pipe (connect and adopt the fused technology of existing heating to get final product), during connection, use threeway connector 4 that three pipes are fixed together every a segment distance, threeway connector 4 can directly be socketed on three pipes, also can adopt the fused mode of heating to be fixed on the tube wall of three pipes, mounting bracket 5 successively on threeway connector 4, railing 6, after all connection is finished, just form the net cage frame of ring-type, water and gas conduit 10 (referring to shown in Figure 3) is installed between base of frame three pipes then, water and gas conduit 10 is communicated with three pipes by hole 11, at inner ring pipe 1, the upper end of outer race tube 2 is installed into blast pipe 12, be installed into drainpipe 13 in the lower end of balance pipe, whole net cage frame just completes.

During use, net cage frame is put into water, hang up netting gear, putting people fry or spat can use.

When not having stormy waves, by air inlet-outlet pipe 12 bubbling air in pipeline, reach certain air pressure after, close the valve of air inlet-outlet pipe 12, whole net cage frame just swims on the water surface, at this moment, inner ring pipe 1 and outer race tube 2 swim on the water surface, and balance pipe 3 then is positioned under water; When storm is coming, open the valve of air inlet-outlet pipe 12, because atmospheric effect, air is discharged by air inlet-outlet pipe 12, and water enters pipeline by the intake-discharge pipe 13 of balance pipe 3 lower ends, the own wt of net cage frame strengthens gradually, net cage can slowly sink, sink to certain water level after (generally be controlled at 6-12 rice gets final product under the horizontal plane) close the valve of air inlet-outlet pipe 12, whole net cage dive is under water, the attack of hiding storm that can safety reduces economic loss.The length of air inlet-outlet pipe 12 should be long as far as possible, is as the criterion still can surface after the net cage dive, so that guarantee that intake and exhaust are unobstructed, available generally speaking flexible rubber hose connects, and then is fixed on cursory the going up of net cage sign and gets final product.

Accurately stable in order to ensure the net cage diving depth, end bob 14 (can make of large-scale stone) can be set in the bottom of net cage, end bob 14 is connected with the net cage frame bottom by chain 15, also can support with the net bottom of netting gear be connected.It is the degree of depth of weighing down at the end when the degree of depth in seabed approximates the net cage dive greatly that 14 Position Design is weighed down at the end, and when the net cage dive, weigh down and touches the seabed at the end, and net cage relies on the just no longer dive of buoyancy of self residual, like this than the degree of depth that is easier to control the net cage dive.

Dive of the present utility model action can be by manual operation, that is, with the valve of Artificial Control air inlet-outlet pipe 12, open and close valve and charge into compressed air etc.; Also can adopt the electronic telecontrol operation, that is, the installation control cabinet is set on air inlet-outlet pipe 12, control circuit (control principle belongs to prior art referring to Fig. 7, repeats no more here) is set in the control cabinet, people are controlled net cage dive come-up on land or ship like this, operate and needn't enter in the water.

Because inner ring pipe 1 has adopted semi-enclosed structure, and water inlet 7 is less, and hole 11 is also smaller, so the air pressure variations in inner ring pipe 1 chamber is slower, when water was poured in by water inlet 7 or flows out, the flow velocity of water can be too not fast like this, and the weight that is to say whole net cage is slowly to change, dive and come-up are slowly carried out, and can not damage netting gear and interior fish spat thereof.In addition, the damping sheets 8 that are provided with in the outer race tube 2 are that the water in the pipe is gone here and there tempestuously and aggravated bump to net cage frame when preventing that wave is higher, can increase the wind wave resistance intensity of net cage.

Fixing of the connection at each pipe joint place of the present utility model and threeway connector, patent (the application number: 01261714.8 that can also adopt the applicant to apply for, the applying date: September 13 calendar year 2001, title: the electric heating pipe joint Net-cage frame), the molten locating piece of electric heating are reinforced, to improve capacity of anti-storm.

In sum, the utlity model has the structural strength height, advantage such as capacity of anti-storm is strong especially is fit to the area that stormy waves is frequent, the stormy waves level is big and uses.
