Abstract
The utility model discloses a self-adsorbing type colliery ambient gas sampler which comprises a compressible container and a sampling tube, wherein a hole is mounted at the top of the compressible container and is connected with a flexible tube, the sampling tube is inserted into the compressible container from a side face, and the compressible container is compressed, evacuated and then is blocked by a plug. The self-adsorbing type colliery ambient gas sampler further comprises a screw lid, wherein the screw lid is fastened outside the hole by a screw. In the self-adsorbing type colliery ambient gas sampler, the diameter A of the compressible container 50 is 10-20cm and the height is 10-30cm. The sampler can be carried conveniently and cannot be broken easily.
Description
Technical field
The utility model relates to a kind of self-priming coal mine environment gas sampler.
Background technology
The colliery is in construction and production run, often be accompanied by the effusion of gases such as gas (methane), carbon monoxide, carbon dioxide, sulfuretted hydrogen, sulphuric dioxide, oxygen, when these gases surpass certain limit when concentration, can produce harm such as blast, therefore, grasp general crack leakage and workplace and leak, the symptom of a trend of discovery accident is at any time in time prevented dangerous generation.
According to the correlation technique requirement, the surrounding air method of sampling has three kinds under the coal mine, is respectively:
Airbag (bladders and Polyvinylchloride bag) sampling method----is applicable to gathers carbon dioxide, oxygen, methane, water-fast gas samples such as carbon monoxide and nitrogen.
The chemical absorbing sampling method---gas samples soluble in water such as gathering oxides of nitrogen, sulfuretted hydrogen, sulphuric dioxide and ammonia be applicable to.
Vacuum sampling method----is applicable to the sulfuretted hydrogen of high-load in the collection mine air and the gas samples such as oxides of nitrogen in sulphuric dioxide and the explosion afterproduct.
Its equipment and instrument are respectively: sampler bag, Podbielniak absorption bottle, vacuum pump, vacuum sampling bottle.And the equal more complicated of these equipment, and reliability is not high, and for example vacuum pump needs power supply, and is fragile; Glass material is frangible.
Also have the coal mine environment gas automatic sampling device of alternate manner, but also substantially all will use vacuum pump.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of self-priming coal mine environment gas sampler at the deficiencies in the prior art.
The utility model adopts following technical scheme:
A kind of self-priming coal mine environment gas sampler, comprise compressible container and sampling pipe, on described compressible container top one hole is set and is connected with flexible pipe, described sampling pipe inserts in the described compressible container from the side, is evacuated after the compression of described compressible container and with described stopper shutoff.
Described self-priming coal mine environment gas sampler also comprises a screw top, and described screw top is by the outside of screw means in described hole.
Described self-priming coal mine environment gas sampler, described compressible container 50 diameter A are 10-20cm, height is 10-30cm.
Use is carried all more convenient, and is difficult for broken.
Description of drawings
Fig. 1 is the utility model structural representation.
10, acquisition port; 20, clip; 30, screw top; 40, stopper; 50, compressible container; 60, flexible pipe; 70 sampling pipes.
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
With reference to figure 1, the utility model is a kind of self-priming coal mine environment gas sampler, it makes compressible container 50 with Polyvinylchloride, on compressible container 50 tops one hole being set is connected with flexible pipe 60, flexible pipe 60 can be used stopper 40 shutoff, and the plug with sampling pipe 70 inserts from the side then, is pumped into vacuum and uses stopper 40 shutoff after compressible container 50 compressions, for the purpose of reliable, cover a screw top 30 thereon.Compressible container 50 diameter A are 10-20cm, and height is 10-30cm.
Package encapsulation is stand-by then.During use, in advance external packing is opened, with gathering the position that the mouth of pipe 10 is placed on needs to gather gas, open clip 20, gas can enter compressible container 50 under suction function, will can finish sampling work on sampling pipe 70 usefulness clips 20 folders then.If the sampling location is far away, personnel are difficult for arriving, and can adopt expansion link that sampling pipe 70 is delivered to the sampling location.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
Claims (3)
