The invention relates to the technical field of
coalbed methane sampling, and discloses a
coalbed methane sampling device for
coalbed methane comprehensive exploration. The coalbed
methane sampling device comprises a fixed protective cover, a
control system and a mobile power supply, wherein a plurality of gas holes are formed in the fixed protective cover; a gas extractor is fixedly arranged in the fixed protective cover; the gas extractor comprises an gas extracting tank; a sealing cover is arranged on an opening in the upper end of the gas extracting tank; an gas inlet
nozzle is arranged atthe lower end of the exhaust tank; a gas
inlet valve is arranged on the gas inlet
nozzle, a
piston is arranged in the gas extracting tank, and the upper end of the
piston rod sequentially penetratesthrough the sealing cover and the top part of the fixed protective cover to be fixedly connected with the telescopic end of the electric telescopic rod; and the fixed end of the electric telescopic rod is fixed on the bracket, the fixed protective cover is fixedly connected with the bracket through a plurality of first connecting rods, and the electric telescopic rod and the gas
inlet valve are respectively connected with the
control system through electric signals. The coalbed
methane sampling device for coalbed
methane comprehensive exploration has the advantages that coalbed methane can beautomatically extracted and discharged by the coalbed methane sampling device, accordingly, the coalbed methane can be conveniently sampled and analyzed, and the coalbed methane sampling device is convenient to use.
