Problems solved by technology
[0003] At present, gas detectors are mainly used to sample the gas in coal mines. Large samplers are not easy to install, so small samplers are often used for sampling. However, some small samplers are troublesome to disassemble and carry, and are not convenient for people. The use of gas has a certain impact on people's detection of gas, and it may cause air to enter during sampling, which affects the inspection of gas, which brings the inaccuracy of gas inspection and has a greater impact

The invention belongs to the technical field of gas collection and discloses a portable gas collecting device convenient to disassemble and assemble. The lower surface of a drill rod joint is fixedlyconnected with a safety seat; the lower surface of the safety seat is fixedly connected with a collecting cylindrical column; the upper surface of the collecting cylindrical column is fixedly providedwith a bearing; the outer surface of the bearing is provided with a first elastic gasket; the lower surface of the collecting cylindrical column is fixedly provided with a supporting seat; the uppersurface of the collecting cylindrical column is fixedly connected with a fixing assembly; and a collecting assembly is arranged in the collecting cylindrical column. According to the portable gas collecting device convenient to disassemble and assemble of the invention, the drill rod joint and the fixing assembly are used in a matched manner; the drill rod joint is connected to a drilling machineso as to be used for collecting a coal seam sample; the rotating column can be rotated, so that the collected gas can be detected; the installation of the device is more convenient; gas content in a coal seam can be accurately detected; and working efficiency and construction safety are improved.
Description
technical field [0001] The invention relates to the technical field of gas collection, in particular to a portable gas collection device that is easy to assemble and disassemble. Background technique [0002] Gas is not only a harmful gas, but also a kind of energy. Its main component is methane, which is easy to explode. Gas explosion has always been a major problem in the mining industry, causing huge casualties and serious losses. Therefore, Generally, before mining, it is necessary to detect and analyze the gas in the coal seam in the coal mine. [0003] At present, gas detectors are mainly used to sample the gas in coal mines. Large samplers are not easy to install, so small samplers are often used for sampling. However, some small samplers are troublesome to disassemble and carry, and are not convenient for people. The use of gas has a certain impact on people's detection of gas, and it may cause air to enter during sampling, affecting the inspection of gas, which bri...
