This invention relates to the field of atmospheric monitoring technology, and more particularly to a
carbon dioxide collection device for atmospheric monitoring, comprising: a support tube; a fixed bracket, conical in shape and fixed to the top of the support tube; a housing, fixed to the upper surface of the fixed bracket, for accommodating a filter
assembly and forming a sampling
airflow channel; a wind-adaptive air intake
assembly, rotatably connected to the upper end of the housing, for automatically turning the air inlet to the leeward side; an air extraction power
assembly, installed inside the fixed bracket, for forming a directional
airflow inside the device; and a negative pressure
storage tank, installed on the bottom plate of the support tube. This invention uses a vertical wing to drive the air intake square tube to automatically turn the air inlet to the leeward side, effectively avoiding direct wind and sand; the
windbreak frame, driven by
wind force, moves a limiting block to lock the fixing ring, stably locking the air intake square tube; this double windproof design avoids wind and sand intrusion, prevents
airflow swaying, and ensures stable and reliable sampling.
