It comprises that overlooking of being connected to form by buoyancy standpipe 2 and buoyancy transverse tube 3 is in anchor 9 at the bottom of regular polygon net cage frame 1, buoyancy riser top pipe cap 5 and bottom, net cage frame bottom lacing wire frame 10, charge and exhaust pipe 12 and is located at balance submerging and surfacing device and the etting 11 in the buoyancy standpipe.Overlook each the drift angle place that is regular polygon net cage frame 1 be provided with two buoyancy standpipes 2 ', i.e. 2 buoyancy standpipes 2 side by side, two buoyancy standpipes 2 ' anchor terminal pad 8 at the bottom of sharing a pipe cap 5 and sharing.Each side of net cage frame 1 is scalariform side rack 4, by 2 buoyancy standpipes 2 and branched buoyancy transverse tube 3, be connected to form, scalariform side rack 4 respectively manage its inner chamber UNICOM each other.In present embodiment, scalariform side rack 4 is " day " font scalariform side rack for the master who is connected to form by 2 buoyancy standpipes 2 and 3 buoyancy transverse tubes 3 looks, as shown in Figure 3, perhaps, for looking, the master who is connected to form by 2 buoyancy standpipes 2 and 4 buoyancy transverse tubes 3 is " order " font scalariform side rack (not shown).Two buoyancy standpipes 2 ' each buoyancy standpipe 2 belong to respectively adjacent scalariform side rack 4.Two buoyancy standpipes 2 ' share in pipe cap 5 have corresponding to two buoyancy standpipes 2 ' pipe and push up the two air chambers by the first air chamber 37 and the second air chamber 37 ' form, and two air chambers link by UNICOM's air flue 38, as shown in accompanying drawing 9,10.Two buoyancy standpipes 2 ' share end anchor terminal pad 8, its back side is connected with the Double bottom anchor 9 corresponding to two buoyancy standpipes 2 ' pipe end.Sharing anchor terminal pad 8 its inboards, the end is provided with for connecting the engaging lug 36 of lacing wire frame 10 in the net cage bottom, as shown in Figure 12.
The balance submerging and surfacing device of being located in the buoyancy standpipe of the present invention, comprise the snorkeling distributed control device 14 of being located at buoyancy standpipe pipe top and the snorkeling single-control apparatus 14 of being located at buoyancy standpipe pipe bottom ', as shown in accompanying drawing 3,4,5,6,7,8,11.
The described snorkeling distributed control device 14 of being located at buoyancy standpipe pipe top, comprise inflation floating balancer 15 and pressure release dive balancer 25.
The described snorkeling single-control apparatus 14 of being located at buoyancy standpipe pipe bottom ', comprise at the bottom of buoyancy standpipe 2 tube chamber inner funnel shape pipes 34, discharge outlet 35 is advanced at the first ball float 33 and the pipe end in tube chamber, as shown in accompanying drawing 3,11.
Charge and exhaust pipe 12 of the present invention is located in the tube chamber of scalariform side rack 4 top buoyancy transverse tubes 3, as shown in Figure 3.Charge and exhaust pipe 12 air flue 33, UNICOM's buoyancy standpipe pipe cap first air chamber 37 within air nozzle 39, buoyancy standpipe pipe top snorkeling distributed control device 14 in buoyancy transverse tube 3 tube chambers, again through pipe cap UNICOM air flue 38 UNICOM's adjacent buoyancy standpipe pipe cap the second air chambers 37 ', as shown in Figure 7.
Below in conjunction with 4,5,6,7,8 pairs of balance snorkeling principles of the present invention of accompanying drawing, be briefly described:
Current state, the net cage dive, in seabed, is full of water in buoyancy standpipe and buoyancy transverse tube.On the spool 22 of the balanced valve 19 of inflation floating balancer 15, move, by 21 shutoff of body wall through hole.Move on the second ball float 31 in balanced valve 29 valve pockets of pressure release dive balancer 25, block valve pocket top leakage port 30.
When net cage floats, compressed air through tracheae 12 to 14 pressurisings of snorkeling distributed control device, at first the second ball float 31 in pressure release dive balanced valve 29 valve pockets is pressed off, with the inflation setting-out, the decline of water level, the first ball float 31 descends thereupon, and blocks the water inlet 32 that loses heart of valve body bottom, so far, the inflatable drainage work of pressure release dive balancer 25 stops.Thereupon, press and continue to increase when inflation, balanced valve 19 spools of inflation floating balancer 15 will be pressed off, spool 22 is moved down, body wall through hole 21 is communicated with valve body top inflation inlet 20, compressed air will make net cage constantly inflate floating through body wall through hole 21 to inflatable drainage in the buoyancy standpipe, and this inflation floating-upward process unanimously continues to net cage and completes floating.
If produce at inflation floating-upward process net cage, floating is uneven, the generation inclination angle.If the right-hand member floating is fast, net cage will occur right high left low, now, the first steel ball 18 of 2 inflation floating balancers 15 of right-hand member, will be along the first inclined ramp 16 to inflation inlet 20 roll, and finally block inflation inlet 20,2 inflation floating balancers 15 of right-hand member are quit work.And the first steel ball 18 of 2 inflation floating balancers 15 of left end is still in the slideway low side, so 2 inflation floating balancers 15 of left end will work on, so, make the rising of floating gradually of net cage left end, last left and right two ends restore balance, and rolls back the again low side of the first inclined ramp 16 of the first steel ball 18 of 2 of right-hand members inflation floating balancers 15 is worked the left and right two ends inflations balancers continuation of floating simultaneously.Principle is shown in accompanying drawing 8.
During by floating state dive, start pressure release when net cage, move on the spool 22 of the balanced valve 19 of inflation floating balancer 15, and block body wall through hole 21, the pressure release dive work of inflation floating balancer 15 is stopped.Now, the second ball float 31 in balanced valve 29 valve pockets of pressure release dive balancer 25 will leave the disappointing water inlet 32 in valve body bottom blocked, and decompression is floated, and so far, pressure release dive work will be born by pressure release dive balancer 25, and until pressure release dive end.
If produce at dive process net cage, dive is uneven, the generation inclination angle.If the right-hand member dive is slow, net cage occurs right high left low, and now, the second steel ball 28 of 2 pressure release dive balancers 25 of left end, will be along the second inclined ramp 26 to leakage port 30 roll, and block leakage port 30, and 2 pressure release dive balancers 25 of left end are quit work.And the second steel ball 28 of 2 pressure release dive balancers 25 of right-hand member is still in the slideway low side, so 2 pressure release dive balancers 25 of right-hand member will work on, make right-hand member dive step-down gradually, to left and right, two ends restore balance, roll the back again low side of the second inclined ramp 26 of the second steel ball 28 of 2 pressure release dive balancers 25 of left end, left and right two end pressure release dive balancers 25 continue again to work simultaneously.Principle is shown in accompanying drawing 8,
Owing to having adopted above-mentioned snorkeling distributed control device 14, when net cage, in the snorkeling process, inclination angle occurs, will be adjusted at any time, return to balance snorkeling state.So, in latent, floating process, constantly produce, along with constantly being corrected, all the time in a kind of dynamically balanced balance snorkeling state, make the absolutely not overthrow accident generation of snorkeling process.
The present invention be located at the snorkeling single-control apparatus 14 of buoyancy standpipe pipe bottom ', as shown in accompanying drawing 3,11, be to match with the snorkeling distributed control device 14 of being located at buoyancy standpipe pipe top, jointly complete the work of balance snorkeling.
