Efficient tunnel air quality detecting system with purifying function

Abstract

The invention relates to an efficient tunnel air quality detecting system with a purifying function. The efficient tunnel air quality detecting system comprises a rail, an emitter, a receiver, a moving mechanism, an adjusting mechanism and an air purifying mechanism. The moving mechanism comprises a moving block, a first motor, a cylindrical gear, a rack and a sliding rod, the adjusting mechanismcomprises a driving chamber, a second motor, a first bevel gear, two adjusting units and an adjusting plate, and the air purifying mechanism comprises a purifying chamber, a draught fan, a filtering assembly and a sterilizing assembly. According to the efficient tunnel air quality detecting system with the purifying function, a CO / VI detector in the efficient tunnel air quality detecting systemis driven to move back and forth along a tunnel through the moving mechanism, meanwhile the height of the CO / VI detector is adjusted through the adjusting mechanism, so that the monitoring range tothe air is widened, dynamic monitoring is achieved, and the monitoring effect is better; and in addition, the air purifying mechanism in the efficient tunnel air quality detecting system can move along with the detector, the purifying range is widened, the purifying effect is enhanced, and therefore the quality of the air in the tunnel can be better improved.

Description

technical field [0001] The invention relates to the field of monitoring equipment, in particular to an efficient tunnel air quality detection system with purification function. Background technique [0002] Tunnel is a special tubular structure. Due to its small space and airtight characteristics, if the exhaust gas emitted by vehicles passing through the tunnel is not discharged in a timely and reasonable manner, it will cause the accumulation of CO and suspended particles, which will directly affect In order to effectively monitor the visibility and CO concentration of the tunnel around the clock for the personal safety of the drivers, passengers and maintenance staff of the vehicles passing through the tunnel, the automatic CO / VI detector has become an indispensable detection equipment in modern traffic. [0003] However, the existing CO / VI detectors still have some defects when they work: for example, because the detector is fixedly installed in the tunnel, it cannot be ...

Problems solved by technology

[0003] However, the existing CO / VI detectors still have some defects when they work: for example, because the detector is fixedly installed in the tunnel, it cannot be moved, and can only monitor the air quality in a part of the range, making the monitoring effect Inadequate; in addition, after the detector feeds back the detected data, the fan will be activated in the tunnel for forced ventilation or other countermeasures will be taken. However, because some tunnels are relatively long, this method has limited effect on improving the air quality in the tunnel of
