Multi-height sampling time-adjustable air pollution monitoring device

Abstract

The invention discloses a multi-height sampling time-adjustable air pollution monitoring device. The device comprises a base; a storage groove with an upward opening is formed in the top surface of the base; a height folding airbag is fixedly arranged on the bottom surface of the storage tank; a lifting block is fixedly arranged on the top surface of the height folding airbag; a connecting rod groove with a leftward opening is formed in the top surface of the lifting block; an extraction mechanism is arranged in the connecting rod groove; an airbag cavity is formed in the right end of the base; an extrusion block is slidably connected into the airbag cavity; an airbag located in the airbag cavity is arranged on the right side of the extrusion block; breather pipes are fixedly connected tothe right end of the airbag in longitudinal symmetry; the left end of the lower breather pipe is fixedly connected with the bottom end of the height folding airbag; an electromagnet is arranged on theleft end wall of the airbag cavity, a lower metal block cavity is formed in the left side of the airbag cavity, a lower metal block is connected into the lower metal block cavity in a sliding mode, air at different heights can be automatically and regularly sampled, and the operation that one device samples air at multiple required heights can be achieved.

Description

technical field [0001] The invention relates to the related technical field of air pollution monitoring, in particular to a multi-height sampling air pollution monitoring device with adjustable time. Background technique [0002] Air pollution monitoring refers to the process of measuring the types and concentrations of pollutants in the air, and observing their temporal and spatial distribution and changing laws. The purpose of air pollution monitoring is to identify pollutants in the air, master their distribution and diffusion laws, and monitor the emission and control of air pollution sources. [0003] The current air pollution monitoring and sampling cannot automatically and regularly sample the air at different heights required, it needs to be manually adjusted to different heights, and it is impossible to realize the operation of one device sampling multiple required heights, and adjust the sampling time interval Complex control devices are required, which are cost-p...
