Described upper shell is provided with buffer structure.
Described buffer structure is: the globoidal structure on edge on upper shell cavity.
The top of described upper shell is provided with suspension ring, and is provided with buckling of being flexibly connected with described suspension ring.
Described upper shell and lower house are being fixedly connected with by spring stainless steel snap close.
Described sampler also comprises bracing or strutting arrangement, and described bracing or strutting arrangement is positioned at the junction of upper shell and lower house.
Described gas collection pipe is polyfluortetraethylene pipe.
Described gas collection pipe is provided with operation valve.
Compared with prior art, the beneficial effects of the utility model are: the air capacity that the sample gas using the utility model to take out contains can not exceed standard, and makes sample purity higher, meanwhile, replace and sample manually, make safer in sampling operation process, convenient.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.As shown in Figure 1, automatic gas sampler, is made up of power supply 1, control system 2, sampler 3, gas collection pipe 4, sampling receptacle 5.Specifically, power supply 1 powers to whole equipment, and control system 2 controls the operation of equipment, and sampler 3 works in drilling fluid 6, gas collection pipe 4 is communicated with sampler 3 and sampling receptacle 5, and the sampling receptacle 5 that the present embodiment uses is the gas collection bags being provided with connecting hole 51.
Sampler 3 shown in Figure 2, by upper shell 31, lower house 32, waterproof machine 33, motor fixing seat 34, stirring vane 35, buckle 36, bracing or strutting arrangement 37 forms.
Shown in Fig. 2, Fig. 3, Fig. 4, upper shell 31 is the cylindrical shells with neck, its upper end closed, lower end is penetrating, a connecting hole 311 is provided with at upper shell 31 neck, an external gas collection pipe be made up of polytetrafluoroethylmaterial material 4, the other end of this root gas collection pipe 4, connects sampling receptacle 5.Edge on the inner chamber of this upper shell 31, arranges in cambered surface, in order that when drilling fluid gushes, can play the effect of buffering.The top of upper shell 31 is provided with suspension ring 312, convenient with buckle 36 and be connected, during work, buckle 36, the position of adjustable sampler 3 by movement.
Shown in Fig. 2, Fig. 3, Fig. 5, the two ends of lower house 32 are penetrating, and are fixedly connected with by spring stainless steel snap close with upper shell 31, in its junction, add one and have certain thickness support ring 37, see Fig. 6, like this, make splicing construction not yielding.A motor fixing seat 34 is placed in lower house 32, see Fig. 7, for placing waterproof machine 33, lower house 32 is divided into two-layer up and down by motor fixing seat 34, the working shaft 331 of waterproof machine 33 is through motor fixing seat 34, extend to lower house 31 lower floor, at the end of working shaft 331, stirring vane 35 is installed.Meanwhile, the position of the corresponding stirring vane 35 of lower house 32, be provided with the liquid outlet 321 that 3 dry are mutually 120 °, drilling fluid is entered by lower house 32 bottom, shunts away from liquid outlet 321.Importantly, motor fixing seat 34 is penetrating, and drilling fluid can be made to flow into upper shell 31 from lower house 32.
Specific implementation process is as follows: when drilling fluid put into by sampler 3, and when noting putting into, collecting pipe interface can not invade below drilling well liquid level, prevents pipeline from blocking.After opening power supply, stirring vane 35 rotates.Fresh drilling fluid is entered by lower house 32 bottom, and meanwhile, stirring vane rotation utilizes centrifugal force to be got rid of by drilling fluid and beats in inner walls, and deviate from gas, old drilling fluid is shunted away from liquid outlet 321.When after motor rotation a period of time, air emptying, connects gas collection bag, collects gas, gas collection pipe 4 can also arrange an operation valve, is convenient to the switch controlling gas collection process.Because the density of gas is lower than the density of drilling fluid, gas floats.After gas floats, the drilling liquid of sampler 3 inside, lower than the drilling liquid outside sampler 3, utilizes pressure reduction to discharge sample gas and enters gas collection bag.After collection is full, the valve on closure set air pipe 4, powered-down, extraction device cleans.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
