Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the tunnel monitoring and early warning box comprises three parts, which are respectively: the device comprises a remote receiving box 1, a dust detection box 2 and a comprehensive detection box 3. A dust detection sensor 4 and a filtering device 9 are arranged in the dust detection box 2; the comprehensive detection box 3 is internally provided with a comprehensive detection sensor device 5 formed by combining other various detection sensors; and a remote PLC receiving device 6 arranged in the remote receiving box 1.
The tunnel monitoring and early warning box mainly has the functions that air is pumped into a detection system through a left fan, the right side of the lower part of the early warning box is provided with two air inlets 7 which are respectively positioned at the right side and the lower part of a dust detection box 2, air can enter from the lower part and the right side, the middle part is provided with a vent 8, and the left side is provided with an air outlet 10; the air inlet 7, the air vent 8 and the air outlet 10 are basically in the same horizontal position, so that air circulation is facilitated.
The lower part left side of early warning case is comprehensive detection case 3, and the right side is dust detection case 2, is equipped with a dust detection sensor 4 in the dust detection case 2, detects dust concentration in the tunnel. The position of a vent 8 between the comprehensive detection box 3 and the dust detection box 2 is provided with a pull-type filtering device 9, so that the functions of filtering dust and other impurities in air can be effectively achieved, and the pull-type structure is convenient for subsequent replacement and maintenance.
The dust detection sensor 4 is separated from other sensors through the baffle, the PLC receiving device 6 is arranged in the remote receiving box 1 above the dust detection sensor, and the hanging hook 11 hanging device on the remote receiving box 1 can fix the remote receiving box 1 and the box bodies of the dust detection box 2 and the comprehensive detection box 3 connected with the remote receiving box on the wall surface of the tunnel.
The device is arranged on a wall of a tunnel, so that narrow space in the tunnel is effectively saved, air circulation near the device is greatly increased, the ventilation area is greatly increased, and the situation that the channel steel is easily corroded in a humid environment is reduced.
The dust sensor is separated from other sensors, so that other sensors are effectively protected from being polluted by impurities in the air, the detection precision and accuracy are improved, and the subsequent device is convenient to detect and clean.
And after the sensor receives the relevant gas detection, the data can be transmitted to the control system, and after the system is processed, the functions of early warning and alarming can be carried out on the current environment.
The comprehensive detection sensor device 5 comprises a temperature and humidity sensor, an NO2 gas detection sensor, a CO gas detection sensor, an O2 gas detection sensor and an H2S gas detection sensor. The method can detect gases such as NO2, CO, O2, H2S and the like in the tunnel.
A controllable fan is also arranged in the comprehensive detection sensor device 5, and the temperature in the box can be reduced if a high-temperature high-heat environment is met; secondly, if excessive dust in the tunnel causes other detection gas not to pass through the filter device 9, the suction force can be enhanced to extract the detection gas to the comprehensive detection sensor device 5 for detection; and thirdly, if the ventilation volume in the tunnel is very low, the ventilation volume in the box can be enhanced, and the ventilation volume is increased, so that the detection function is achieved.
Still be equipped with alarm device on the tunnel control early warning case, alarm device adopts mining alarm lamp, detects relevant gas through comprehensive testing sensor device 5, and when gaseous numerical value reached the alarm value, just start audible and visual alarm through PLC transmission control signal.
The detection bus cable that tunnel control early warning case adopted adopts the armoured cable of taking the shielded wire to external explosion-proof face can effectively reduce the harm that rubble and other blasting brought in the tunnel, wide application in tunnel, chemical industry, oil well.
Under the restriction of narrow space size, the large ventilation requirement is met. The pull-type filtering device 9 effectively isolates the interference of dust and other impurities in the air to the detection of the sensor, increases the accuracy of detection and facilitates subsequent detection and replacement. The situation that the channel steel is easily corroded in a humid environment in a plateau tunnel environment is effectively reduced. After sampling and transmitting acquisition information to the environment, early warning can be carried out on the current environment.
In the tunnel ventilation detection system, because the mixed gas and the dust in the tunnel are too much, firstly, the dust sensor and other sensors need to be separated, and a pull-type convenient filtering device 9 is additionally arranged in the middle, so that the dust concentration in the tunnel is effectively detected, and the interference condition of the dust in the air to other gases is filtered, and secondly, because the space position in the tunnel is narrow, the air circulation is inconvenient.
