Portable environment monitoring device

Abstract

The invention belongs to the technical field of environment monitoring, and particularly relates to a portable environment monitoring device. The portable environment monitoring device comprises a detector body, a supporting table is arranged at the bottom of the detector body, and a clamping plate is arranged at the bottom of the supporting table; a rotating shaft is connected to the top of the detector body through a bearing, a strip-shaped plate is arranged at the top of the rotating shaft, a hydraulic rod is arranged at the end of the strip-shaped plate, and an exhaust pipe is installed in the hydraulic rod; a storage device is arranged on the top of the supporting table. An inclined plate is blown to move to drive an air storage cylinder filled with air to rotate, wind enables a hydraulic rod at the end of a strip-shaped plate to rotate to the leeward position of a detector main body, large particles in the air are gradually precipitated in the rotating process of the air storage cylinder, and meanwhile, particles in the air collide with the inner wall of the air storage cylinder, so that the precipitation effect is improved; impurities sucked into the detector main body can be reduced, the cleaning interval time is prolonged, and the probability that the end part of the exhaust pipe is blocked can be reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, in particular to a portable environmental monitoring device. Background technique [0002] Environmental monitoring refers to the determination of environmental quality (or pollution level) and its change trend through the determination of representative values ​​of factors affecting environmental quality. The process of data collection, analysis and synthesis, in general, is the process of planning-sampling-analysis-comprehension to obtain information. The main means of environmental monitoring include physical means (monitoring of sound and light), chemical means (various chemical Methods, including gravimetric method, spectrophotometry, etc.), biological means (monitoring the impact of environmental changes on organisms and biological communities), according to the monitoring objects, environmental monitoring is divided into two types: environmental quality monitoring and poll...

AI Technical Summary

Problems solved by technology

[0003] When performing air monitoring, it is necessary to pump air into the detector for detection, but when performing detection in an environment with a lot of dust, such as on both sides of the road, when the wind blows, the wind will carry the dust on the road surface, resulting in flying dust. , so it is necessary to install a filter at the exhaust end when pumping air. The impurities filtered by the filter will affect the entry of other detection components in the air. At the same time, if the filter is blocked for a long time, it will affect the subsequent detection work.
