Description

Technical Field

[0001] The utility model relates to the field of methane measuring device verification devices, in particular to an adjustable multi-channel catalytic combustion type methane measuring device verification device. Background Art

[0002] The catalytic combustion methane detector is a precision electronic instrument that uses the carrier thermal catalytic principle to quickly and accurately measure the methane gas concentration in coal mines. Its accuracy is related to the accuracy of the coal mine underground production environment monitoring data, and thus to the safety of underground coal mine production.

When the device drives the rotating shaft to rotate through the micro servo motor, the first connecting rod is driven to rotate in the same direction and at the same speed through the pulley and the transmission belt, and the two moving wheels are driven to move in opposite directions at the same speed through the first spur gear and the second spur gear. The two moving wheels are respectively fitted with the two sides of the inner wall of the guide rail, and rotated by the moving wheels.
