The operation principle of deep water mesh cage jacking system of the present invention is as follows:
1) net cage dive
Remote user terminals sends dive instruction to described master controller, and described in described main controller controls, reversal valve 24 works in S position, and now, conducting between the A mouth of described reversal valve 24 and C mouth, makes the water filling room 11 of described sinker 10 be connected with sea external environment condition.Simultaneously, described water filling room 11 is also connected with deep water external environment condition, therefore under the effect of external seawater pressure, seawater injects described water filling room 11 by described water injection hole 12, seawater extrudes the gas in described water filling room 11, makes original gas in described water filling room 11 flow out to sea external environment condition from described injecting hole 13 by described gas ducting 60.
Finally, fill seawater in described water filling room 11, under self gravitation effect, described sinker 10 drives net cage dive.
2) net cage floats
Remote user terminals sends floating instruction to described master controller, described in described main controller controls, heater 22 heats, the temperature of described gas generating chamber 211 is made to reach in certain temperature range, in this temperature range, chemical substance in described gas generating chamber 211 can produce chemical reaction and generate gas, and described air bag 21 is expanded.
In addition, described in described main controller controls, reversal valve 24 works in N position, and now, conducting between the A mouth of described reversal valve 24 and B mouth, makes the water filling room 11 of described sinker 10 be connected with the plenum chamber 25 of described float 20.Described plenum chamber 25 is extruded because described air bag 21 expands, gas pressure in described plenum chamber 25 is increased, and then, gases at high pressure extrude seawater and enter described water filling room 11 from described gas ducting 60, and the seawater in described water filling room 11 is extruded into external environment condition by gas from described water injection hole 12.
Finally, gassy in described water filling room 11, the overall buoyancy of net cage and sinker 10 etc. is greater than self gravitation, and net cage floats.
3) net cage dive preparation again
After net cage floats, described in described main controller controls, reversal valve 24 works in meta, maintains gas in described water filling room 11 and does not leak.Afterwards, intake valve 27 opened by described master controller, and controls the temperature range that described heater 22 makes the temperature of described gas generating chamber 211 be adjusted to can to occur the chemical reaction consuming gas.Now, described air bag 21 shrinks, and the gas of external environment condition enters described plenum chamber 25 from described intake valve 27.Treat that described plenum chamber 25 returns to reset condition, described master controller cuts out described intake valve 27, waits for dive control instruction again.
