AI Technical Summary
Existing automatic control devices for greenhouse gas detection suffer from spatial limitations during sample collection, leading to errors in the measurement of samples from different areas. Additionally, the presence of suspended impurities in the air can also affect the measurement results.
A device was designed that includes a gas detector, a gas collection box, a sleeve, a rotating tube, a drive mechanism, a piston mechanism, a filter mechanism, and a transmission mechanism. The drive mechanism drives the sleeve and the rotating tube to rotate in opposite directions. Air is drawn in by the fan and the piston mechanism, filtered by the filter mechanism, and the transmission mechanism causes the filter mechanism to vibrate, ensuring uniform mixing and filtration of the air and improving detection accuracy.
It achieves uniform collection and mixing of air from different directions, reduces errors caused by uneven distribution of air components, improves the accuracy of gas detection and the uniformity of sample detection, and ensures the reliability of measurement results.
