Road dust on-line monitoring device

Abstract

The invention discloses a road dust on-line monitoring device, and relates to the technical field of dust particulate matter concentration monitoring, the road dust on-line monitoring device comprises a monitoring device body, a right top plate, a left top plate, a right ring cover, a left ring cover and a climbing device, the right ring cover is arranged on the right side of the monitoring device body, and the left ring cover is arranged on the left side of the monitoring device body; a connecting rod is fixedly connected to the top of the right ring cover, a right top plate is mounted at the top end of the connecting rod, a left top plate is mounted at the top of the left ring cover through the connecting rod, a first fixing plate is mounted on one side of the right top plate, a threaded rod is fixedly connected to one side of the first fixing plate, and a second fixing plate is fixedly connected to one side of the left top plate. The monitoring device has the advantages of being reasonable in structure, high in wind resistance and convenient to install, the monitoring device surrounds the surface of the municipal rod body in a circular ring shape, the monitoring device can move up and down to freely adjust the height to collect data of flying dust in air at different heights, the accuracy of the monitoring data is improved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of dust particle concentration monitoring, in particular to an online monitoring device for road dust. Background technique [0002] Flying dust is an open pollution source that enters the atmosphere due to the dust on the ground being driven by wind, human or other factors. It is an important part of the total suspended particles in the ambient air. The flowing air caused by indoor ventilation and the airflow generated by the rotation of the moving parts of the equipment will firstly separate the fine dust in the powder and particles from the powder and fly up, and then cause the dust to diffuse due to the flow of indoor air, thus completing the separation from the dust. From the generation to the diffusion process, the dust online monitor can detect the dust in the air. [0003] The existing technology has the following deficiencies: because the existing monitoring equipment can only be fixed at one place...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention provides an on-line monitoring device for road dust. The outer surface of the threaded rod is threaded to connect the self-locking nut. The board is bent at 30 degrees, and several groups of rubber ribs are installed on the surface of the rubber track to solve the problem that the road dust monitoring device cannot move up and down, and the dust at high and low places cannot be monitored, resulting in inaccurate monitoring data.
