AI Technical Summary

Technical Problem

Existing underground ventilation systems in coal mines are unable to quickly and effectively block fires or abnormal gas leaks at the intersections of ventilation lines, leading to the spread of toxic and harmful gases and affecting the stable regulation of the entire ventilation network.

Method used

Anomalies are detected by a carbon dioxide sensor. The processor controls the drive unit to drive the sliding box and the elastic moving parts to achieve physical isolation of the abnormal branch. When needed, it can form an S-shaped ventilation path or merge channels to adjust the air volume and air pressure.

Benefits of technology

It enables rapid isolation of a single branch under abnormal conditions to prevent gas diffusion, and regulates air volume and air pressure under normal conditions, thereby improving the stability and flexibility of the ventilation system.

Abstract

The application provides a coal mine underground ventilation system air volume intelligent monitoring and adjusting system, relates to the ventilation technical field, and comprises a box body, a connecting flange for connecting at least two gas channels is arranged on one side of the box body, and a partition plate for separating the two gas channels is arranged in the box body. The application is provided with a processor capable of receiving carbon dioxide sensor signals, a driving piece driven by the processor, a box body slidingly driven by the driving piece, and a moving piece elastically matched with the box body, so that when an abnormality occurs, the processor controls the driving piece to push the corresponding side box body to translate, the moving piece shields the air inlet end of the side and causes the two bridge ends to be misaligned, thereby cutting off the communication between the branch and the box body, and the unaffected branch maintains normal ventilation.
