AI Technical Summary
In existing tunnel excavation and construction, the filter components of hazardous gas monitoring equipment cannot be automatically cleaned in high dust environments, resulting in dust accumulation that affects the monitoring effect. Furthermore, dust dispersion during the cleaning process interferes with the detection and cannot guarantee the sealing of the gas flow channel.
A pump-suction gas detector was designed, equipped with a cleaning mechanism and a drive mechanism. Through the cooperation of the plug and the beater, the filter element is automatically cleaned by beating, and the suction pipe is sealed during the cleaning process to prevent dust from spreading.
It enables automatic cleaning of filter components in high-dust environments, ensuring the sealing of the gas flow channel of the monitoring equipment, avoiding dust interference with monitoring results, and improving cleaning efficiency and monitoring accuracy.
