(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of the utility model plenum chamber;
Fig. 3 is the vertical view of the utility model tube-like base.
In figure, 1 tube-like base, 2 grooves, 3 plenum chambers, 4 draft tube, 5 air admission holes, 6 escape pipes, 7 T-valve, 8 injector syringes, 9 gas sampling bags, 10 fans, 11 switches, 12 pilot lamp, 13 batteries, 14 thermometers.
(5) embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Fig. 1-Fig. 3, this embodiment comprises that one opens the tube-like base 1 arranging up and down, upper end face at tube-like base 1 is provided with a circle groove 2, the lower end sealing of the open plenum chamber 3 arranging in one bottom is inserted in groove 2, plenum chamber 3 upper end sealings arrange, in plenum chamber 3, be provided with the some draft tube 4 that vertically arrange, in every draft tube 4, be provided with several air admission holes 5, guarantee homogeneity and the representativeness of gas, the lower end of one escape pipe 6 is connected with the upper end of some draft tube 4 respectively, the upper end of escape pipe 6 is connected with a port of T-valve 7 after stretching out plenum chamber 3, another two ports of T-valve 7 are connected with the air intake opening of injector syringe 8 and gas sampling bag 9 by flexible pipe respectively, gas sampling bag 9 is connected with T-valve 7, can greatly facilitate gas production operation like this, in plenum chamber 3, be provided with a fan 10, fan 10 is connected with battery 13 with pilot lamp 12 through being located at the switch 11 of plenum chamber 3 outside top by wire, in sampling process, can utilize the beating action of fan 10 that the gas in plenum chamber 3 is mixed, further improve the representativeness of the gas gathering.According to floristic difference, the time that fan 10 rotates is also different, generally rotates 3-6 minute, to guarantee that the interior gas of plenum chamber 3 can mix; On plenum chamber 3, be provided with the thermometer 14 that a temperature-sensitive end stretches into plenum chamber 3 inside, at any time the temperature in measuring set gas tank 3; Between the lower end of described plenum chamber 3 and groove 2, adopt water-stop; The U-lag that described groove 2 is opening upwards; Described plenum chamber 3 is transparent plenum chamber; Described plenum chamber 3 is PPR plenum chamber, and what material was selected is atactic copolymerized polypropene (PPR) material, and the advantage of this material is heat-insulation and heat-preservation; Described some draft tube 4 length not etc., can not collect in plenum chamber 3 from top the gas of the diverse location of bottom; Described tube-like base 1 is metal tub base; Described draft tube 4 and escape pipe 6 are PVC flexible pipe, to the absorption of gas and permeate minimum.
Tube-like base 1 lower end is shifted to an earlier date to indentation test Tanaka, and make uniform with surveyor's staff, guarantee that tube-like base 1 is steady, prevent the in use unbalance gas leakage of this gas collecting device, then the lower end of plenum chamber 3 is inserted in the groove 2 of tube-like base 1 upper end face, to injected water in groove 2, seal again, can make like this sealing of harvester more reliable, at utmost reduce due to the bad error causing of sealing, plenum chamber 3 is buckled on tube-like base 1, plenum chamber 3 just can not act directly on soil like this, can not cause disturbance or injury to soil and plant.Before on-test, first that the air in gas sampling bag 9 is emptying.During on-test, open switch 11, pilot lamp 12 is bright, fan 10 starts to rotate simultaneously, with injector syringe 8, by T-valve 7, through escape pipe 6 and draft tube 4, the gas in plenum chamber 3 is extracted in gas sampling bag 9 again, then emptying, gas sampling bag 9 is repeated to aforesaid operations, carry out repeatedly gas collection and emptying.Until fan 10, rotate after 3-6 minute, can carry out the collection of gas, with injector syringe 8, by T-valve 7, through escape pipe 6 and draft tube 4, the gas in plenum chamber 3 is extracted in gas sampling bag 9 again, complete sampling.After sampling finishes, by switch 11, close fan 10.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
