Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in figure 1, a kind of system for obtaining gas in soil, including harvester and collection device, the collection dress
Put and be embedded in soil, the collection device is in outside soil, and the harvester connects institute by silica gel appendix 5
Collection device is stated, the gas gathered is simultaneously transported to the collection dress by the gas of the harvester collection respective layer position soil
Put and save, it is specific as follows：
The harvester includes 4, two collection tubes 1 of the first glass tube and a delivery pipe 2；Two collection tubes 1
It is embedded in soil, netted air admission hole, and one end of two collection tubes 1 is equipped with two collection tubes 1
Closing, the other end of two collection tubes 1 is got up by the horizontal docking of two of which interface of three-way connection 3, described defeated
One end of pipe 2 is sent to connect the 3rd interface of the three-way connection 3, the other end of the delivery pipe 2 is vertically up to
Outside soil；The both ends of the delivery pipe 2 are provided with sealing-plug, and first glass tube 4 is in the delivery pipe 2 and through two
The sealing-plug, one end of the silica gel appendix 5 is connected in the upper end of first glass tube 4.First glass tube 4 is set
In delivery pipe 2, the first glass tube 4 can be avoided to be extruded and damaged by soil；If directly set in delivery pipe 2 in addition
Silica gel appendix 5 has following two：
1. the easily aging in the wild of the silica gel appendix 5 of quality of rubber materials, it will change within general 1 year；2. quality of rubber materials is defeated
Tracheae 5 is easily flattened, and causes gas to be difficult to gather.
The collection device includes inverted gas bottle 6, the second glass tube 10, the 3rd glass tube 11, the and of silica gel air inlet pipe 7
Silica gel drainpipe 8；The bottle sealing of the gas bottle 6 has rubber stopper, and described one end of second glass tube 10 is in the gas bottle 6
Bottleneck outside, the other end of second glass tube 10 runs through after the rubber stopper in the gas bottle 6 and close to bottle
The opening position of mouth, described one end of 3rd glass tube 11 are in outside the bottleneck of the gas bottle 6, and the 3rd glass tube 11 is in addition
One end is run through after the rubber stopper in the gas bottle 6 and close to the opening position of bottom of bottle；Nothing is full of in the gas bottle 6
The water body of foreign gas；One end that one end of the silica gel drainpipe 8 is in outside the bottleneck of gas bottle 6 with second glass tube 10
Connection, the other end of the silica gel drainpipe 8 extend downwardly；One end of the silica gel air inlet pipe 7 and the 3rd glass tube 11
