AI Technical Summary

Technical Problem

The existing filter membrane-type air sampling monitoring device requires frequent replacement of the filter membrane during long-term atmospheric monitoring, which is inconvenient to operate and increases monitoring costs.

Method used

An air sampling monitoring device for air pollution control is designed. The air sampling module is used to cooperate with multiple placement racks. The movement of the air extraction module drives the air flow through the filter membrane on the placement rack to realize air sampling, and the weight of the filter membrane is monitored in real time through the gravity sensing unit.

Benefits of technology

It improves the efficiency of air sampling, reduces labor costs, realizes highly automated air sampling monitoring, and can continuously perform atmospheric monitoring over a long period of time.

Abstract

The present invention relates to the field of environmental monitoring technology, and specifically to an air sampling monitoring device for air pollution control, comprising an adjustment column, a lifting slot is provided on the outer wall of the adjustment column, a lifting module is sleeved on the outer side of the adjustment column, the lifting module is slidably connected to the lifting slot, a mounting ring is provided on the outer side of the lifting module, a number of evenly distributed connecting rods are fixedly installed between the inner ring wall of the mounting ring and the lifting module, a driving slot of a circular ring structure is provided on the outer wall of the mounting ring, a driving slider is slidably installed in the driving slot, and a driving slot extends from one side of the driving slider and is fixedly installed with an exhaust module. The present invention designs a placement rack, which can be aligned with several placement racks in turn through the movement of the exhaust module. When the exhaust module is aligned with the placement rack, it can drive the airflow through the filter membrane on the placement rack to achieve air sampling, which greatly improves the efficiency of air sampling.
