Abstract
The invention discloses a method for recovering helium from an anchored aerostat. The method is characterized in that helium is recovered when the aerostat is kept anchored, so that the aerostat can maintain the shape and the anchored status while about 40 percent of helium is recovered from the aerostat. The wind resistance of the aerostat is greatly improved during the process. Meanwhile, while the aerostat is transferred to a disassembly and recovery area, the transfer difficulty is correspondingly lessened and the safety is improved due to the fact that the buoyancy of the aerostat is reduced by about 40 percent.

(5) remove the engine on aerostatics and load object when aerostatics starts to decline, maintain aerostatics and be in floating anchored condition;
(6) when the volume percent being filled with air in aerostatics associated airbag reaches 85%-95%, preferably 90% time close helium recovery machine, A helium recovery tracheae is separated with the helium air valve of aerostatics head;
(7) open helium recovery machine after aerostatics transfer helium being reclaimed through step (1) to (6) to continue to reclaim helium;
(8) remove the voltage-controlled system of aerostatics and load equipment, the air in associated airbag is extracted out.
Wherein, after step (8), also comprise the step will remaining helium with helium recovery machine in aerostatics and extract out completely; Described step (8) is extracted out by the air in associated airbag with aerofoil fan.Aerostatics retrieving arrangement described in step (1) is the conventional equipments such as aerostatics recovery vehicle.Aerostatics of the present invention is also the aerostatics of this area routine, as mooring ship etc.Described mooring mast is also conventional mooring mast structure (mooring mast rotation platform is provided with rotation seal joint) in this area.
Below in conjunction with principle, the invention will be further described:
Before helium recovery, aerostatics is in anchored condition, and aerostatics and mooring mast do not depart from, and voltage-controlled system still powers on and in running order.Be connected with the helium gas charging valve on utricule by helium recovery tracheae 1, helium recovery tracheae 1 the other end is connected with helium recovery tracheae 2, helium recovery machine by the rotation seal joint be arranged on mooring mast rotation platform.Start helium recovery machine, start to carry out helium recovery.Voltage-controlled system is filled with air to adjust aerostatics utricule internal pressure in trend associated airbag in the process, the ship shape maintaining aerostatics ensures aerostatics intensity, simultaneously, when running into the severe weather exceeding survival wind speed, aerostatics will rotate with the wind and automatically enter deflection arch state windward, and the wind that greatly reduction aerostatics bears carries.When aerostatics rotates, the helium recovery tracheae of mooring tower top makes it still normally be connected with helium recovery machine and continue helium recovery by rotation seal joint.Be filled with after 90% air until associated airbag, suspend helium recovery, aerostatics is transferred to fixing dismounting region, starts disassembly & recycling work.Helium now in aerostatics utricule has completed the volume of recovery about 40%, in this process, because aerostatics still can maintain ship shape, avoid at this one-phase that ship capsule goes for a drive, aerostatics wind carries the situation that sharply increasing causes aerostatics to damage and occurs because aerostatics can not keep ship shape to cause.
Compared with prior art, the inventive method just can carry out helium recovery operation at anchored condition at aerostatics, make still can maintain ship shape in the time period of aerostatics helium recovery about 40% and be in anchored condition, in the process, the wind resistance of aerostatics is greatly improved.Meanwhile, when aerostatics is to disassembly & recycling zone-transfer, the buoyancy due to aerostatics decreases about 40%, and difficulty during transfer is corresponding reduction also, and security have also been obtained raising.
