At the same time, the moving mechanism adjusts the position and distance of the atmospheric monitor 5. The cooperation between these mechanisms greatly increases the atmospheric monitoring range of the atmospheric monitor 5. The atmospheric monitor 5 transmits the monitored data to the monitoring data control display screen 7. When relevant personnel need to understand the monitoring data, the electric push rod 17 extends, thereby moving the lower monitoring data control display screen 7 to the lower end of the protective box 6. When the data does not need to be read, it returns to the inside of the protective box 6, effectively protecting the monitoring data control display screen 7.
