The air pump model that the present invention adopts is 3HBB.34303X, 700kPa vacuum pump model VCA5036B-24V maximum pressure 50kPa, and the speed of evacuation is 60l/min; Vacuum diaphragm pump model is Gm-1.0A, and extreme pressure is 0.08MPa, and the speed of evacuation is 386/min.
Below, by reference to the accompanying drawings technical scheme of the present invention is further described again:
A device for gas is extracted in the shutoff of ice sheet shallow-layer névé penitent hole, mainly twists pipe wheel hub 13, twisted wire hub bracket 14, air pump 18, vacuum pump 20, vacuum diaphragm pump 22, carbonoxide real-time analyzer 26, gas-holder 27, accumulator jar 29 and generator 31 by air bag 4, pulley and forms.Air pump 18 has a valve interface, and vacuum pump 20 and vacuum diaphragm pump 22 have two valve interfaces respectively.Air bag 4 is filled in ice hole 11, and its two ends lock ring, in air bag upper plug head lock ring lid 10 and air bag lower end cap lock ring lid 3, tightens with screw respectively.Air bag lower end cap lock ring lid 3 consolidation air cavity dividing plate 2 and visit end protection ring 1, is inserted with the first fast pump mouth 7, gas bag inflating valve 8 and first air exhaust nozzle 9 at a slow speed in air bag upper plug head lock ring lid 10 jack.First fast pump mouth 7 times termination fast pump pipe 6, fast pump pipe 6 through the second fast pump mouth 7 ' of air bag lower end cap lock ring lid 3 air bag lower end cap lock ring lid 3 and air cavity dividing plate 2.First air exhaust nozzle 9 times terminations exhaust tube 5 at a slow speed at a slow speed, at a slow speed exhaust tube 5 through air bag lower end cap 3 second at a slow speed air exhaust nozzle 9 ' at air bag lower end cap lock ring lid 3 with visit end protection ring 1.The effect visiting end protection ring 1 and air cavity dividing plate 2 prevents by blocking pipe in exhaust tube press-in hole prodelta clay snow deposit, forms the little separation collection chamber of extracting gases simultaneously; First fast pump mouth 7, gas bag inflating valve 8 and first at a slow speed air exhaust nozzle 9 upper end connect the first gas-filled tube 12, second gas-filled tube 12 ', the 3rd of bleeding of bleeding respectively and to bleed gas-filled tube 12 " by twisted wire hub bracket 14 top sheave strand pipe wheel hub 13; be connected on gas-filled tube 17 and insert air pump 18 valve mouth with the second gas-filled tube 12 ' of bleeding with quick inflating nozzle 19, gas-filled tube 17 is provided with the first valve 33 and the first pressure gauge 34; The fast aeration pipe 16 be connected with gas-filled tube 12 of bleeding inserts vacuum pump 20 1 valve mouths with fast pump mouth 35, and another valve mouth is inserted quick outlet nozzle 21 and is connected with capnograph 26 by the second valve 24 on sebific duct 25; Bleeding gas-filled tube 12 with the 3rd, " exhaust tube at a slow speed 15 be connected inserts vacuum diaphragm pump 22 1 valve mouths with outlet nozzle 23 at a slow speed, and the outlet nozzle at a slow speed 37 that another valve mouth of vacuum diaphragm pump 22 inserts is connected with sampling jar 27 with the second pressure gauge 36 by the 3rd valve 28 on sebific duct 25; Air pump 18, vacuum pump 20 and vacuum diaphragm pump 22 are placed in dolly 30 framework, under accumulator jar 29 and generator 31 are placed in framework, generator 31 is connected with inflator pump 18, vacuum pump 20 and vacuum diaphragm pump 22 by wire respectively with accumulator jar 29, and climbing rope 32 ties up on the suspension ring of air bag upper plug head lock ring lid 10.
Granular snow layer on the South Pole and ice sheet general thickness are at 50-120 rice.Generally carry out together in conjunction with ice core rig with gas sample in layer granular snow layer hole, namely get a sample for every 8 meters.When ice core rig gets into predetermined sampling depth, propose rig, put into air bag 4 and carry out gas sample.Detailed sampling process is first tied up to by a climbing rope 32 on the suspension ring on air bag upper plug head lock ring lid 10, the lower end of air bag 4 is moved on to hell, climbing rope 32 and air bag 4 are followed and are entered in boring, exhaust tube 15 at a slow speed, air bag 4 is slowly put into foot of hole by the pulley strand pipe wheel hub 13 in twisted wire hub bracket 14 by fast aeration pipe 16 and gas-filled tube 17, connect after at the bottom of the spy of quick inflating nozzle 19, protection ring 1 touches the end until air bag 4, open inflation first valve 33, open inflator pump 18 and be pressed into air in air bag 4, air bag 4 is expanded and blocks boring, prevent gas from flowing into collection chamber.Air pressure in air bag 4 can be obtained by pressure gauge 33.Close the first valve 33 when air pressure in air bag 4 reaches predetermined pressure, now, air bag 4 is by bore closed.
On twisted wire hub bracket 14 top sheave strand pipe wheel hub 13, Rapid inhalation pipe 16 and at a slow speed air intake duct 15 are connected respectively to quick valve 21 and at a slow speed on vacuum noz(zle) 23, open the second valve 24, fast pump pump 20 and aspiration pump 22 at a slow speed, by the air intake duct of 100 meters long, bleed through fast pump pump 20, the gas of foot of hole is extracted by Rapid inhalation mouth 7 and drills through ice core and put into air bag and be mixed into the ambient atmosphere of granular snow layer hole, the gas sucked by quick valve 21 enters carbon dioxide real-time analyzer 26, the CO be used in Real-Time Monitoring gas
2concentration.In accumulated snow gas extraction process, this concentration is by lentamente from the CO of modern environment air
2concentration level (this causes because air is pressed in boring by air bag piston effect) drops to a constant value.When carbon dioxide content continues to be reduced to a stationary value, can assert that the ambient atmosphere drilling through ice core and put into air bag and be mixed into granular snow layer hole is excluded entirely.Then, the second valve 24 is closed.Along with extracting constantly carrying out of boring Atmospheric processes, the gas in granular snow hole is constantly taken away, and the gas simultaneously in periphery granular snow layer hole constantly supplements again.At this moment the gas around foot of hole collection chamber in granular snow layer hole and in gas outlet can assert it is original gas in this layer of position granular snow layer hole.Start vacuum diaphragm pump 22, and open the 3rd valve 28, gaseous sample is passed through outlet nozzle 37 at a slow speed and be compressed in sampling jar 27, observe gaseous tension in sampling jar 27 by tensimeter 36, when reaching sampling jar 27 predetermined pressure, close vacuum diaphragm pump 22 and the 3rd valve 28.After having sampled, close all pumps and valve, finally open the first valve 33, get rid of gas in air bag 4, silicone tube 25 is rotated by twisted wire hub bracket 14 top sheave strand pipe wheel hub 13, slowly climbing rope 32 and air bag 4 is proposed from boring.Remove pulley twisted wire hub bracket 14.Again ice core rig being put into boring, proceed ice core and drill through work, when reaching the next predetermined gas sample degree of depth, repeating above-mentioned experiment sampling process, until rig bores ice sheet granular snow layer.
