Description

Technical Field

[0001] The utility model belongs to the technical field of poisonous gas detection, in particular to a positioning device for a poisonous gas alarm. Background Art

[0002] A toxic gas alarm is a safety device that detects the concentration of toxic gases in the environment and sounds an alarm to remind people to take appropriate protective measures. It mainly monitors the concentration of toxic gases in the air through sensors or transducers, and triggers an alarm when the concentration exceeds a set threshold. When the concentration of toxic gases exceeds the set safety threshold, the alarm will generate sound and light signals to remind nearby personnel to take emergency measures or evacuate the scene. Because the installation and positioning structure of the toxic gas alarm in the related technology does not have a position adjustment function, the monitoring range of the toxic gas alarm is limited. The concentration of toxic gases in a specific area may not be accurately monitored, which affects the ability to issue an alarm in a timely manner. In some industrial sites or laboratories, the source of toxic gas leakage may be unevenly distributed in space. If the position of the alarm cannot be adjusted, it cannot flexibly meet the monitoring needs in a specific environment. Summary of the invention
