Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of gas sampling assembly divided for coal mine gob spontaneous combustion three with dynamic, as shown in Figure 1 to Figure 2, including
Beam tube, beam tube is combined by several single tubes 1 and outside extrudes outer sheath and forms, and beam tube front end is provided with sampling protective device, is prevented
Protection unit includes single tube connector 3, dust filter unit 4 and protective case 2, and the end of single tube 1 connects dust-filtering by single tube connector 3
Device 4, is provided with protective case 2 between the single tube 1 and dust filter unit 4, the protective case 2 is that several metal tubes removably connect
Connect composition.Each single tube 1 in beam tube extends to each goaf and carries out gas collecting, and single tube 1 is responsible for the collected sample of transport
Gas, single tube 1 are directly connected with single tube connector 3, and effect is that single tube 1 is protected not smashed by the falling rocks in goaf, to guarantee sample
Gas can normal acquisition, protective case 2 is spirally connected by the screwed metal tube of multistage, can increase and decrease gold according to the distance in goaf
Belong to the quantity of pipe to adjust the length of protective case 2；Dust filter unit 4 is in the front end of sampling, for removing the dust in sample
Moisture, guarantee that the sample gas adopted is pure.
Further, as shown in Figure 1,2 sets of the protective case outsides in single tube 1,2 one end of protective case connect dust mistake
Filter 4, single tube connector 3 are located at the inside of protective case 2 and are arranged on dust filter unit 4, and the end of single tube 1 connects single tube connector
3.The structure enters single pipe direct female connector is sampled in sheath steel pipe, and connect with dust filter unit 4, and sample gas is straight by dust filter unit 4
