Device for detecting and warning toxic gas

摘要

The present invention analyzes air components existing in a pipeline or an underground space at a construction site to alert the user when a harmful component is detected, thereby enabling to cope with safety accidents in advance. It is possible to install and move in a very simple structure, And a driving means including a first rotating roller and a second rotating roller which are mutually rotationally driven in a face-to-face contact with the guide cable; Wherein an encoder for detecting the operation of the first rotating roller is further provided on the second rotating roller; A pulse detecting section for detecting a pulse value input through the encoder; a gas detecting section for detecting a gas component in the air through a gas sensor; and an alarm section for issuing an alarm when detecting a noxious gas in the air, A storage unit for storing and storing the detected gas component data according to the moving distance and the moving distance of the noxious gas detection and notification apparatus; And outputs a warning command to an alarm unit when a harmful gas is detected as a result of the analysis, and at the same time, a warning light is sent to the warning light unit And a control unit for outputting a lighting command.
