Description
Technical field
The utility model relates to a kind of environmental gas parameter alarm, is specifically related to a kind of methane oxygen two parameter alarms.
Background technology
Under coal mine with special operation environment such as chemical metallurgy in, often adopt methane oxygen two parameter alarms that oxygen concentration in the environment and methane concentration are monitored in real time.Methane oxygen two parameter alarms utilize methane concentration and the oxygen concentration in methane analyzer and the oxygen determinator difference monitoring of environmental; Whether the concentration value that microprocessor judges in the instrument monitors surpasses the secure threshold of setting, and instrument sends alerting signal when surpassing secure threshold.And existing methane oxygen two parameter alarms have in the selection of structural design and components and parts assembling that volume is big, operation and maintenance is inconvenient, sealing difference or the low shortcoming of monitoring precision.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide that a kind of volume is little, in light weight, simple to operation, easy to maintenance, good seal performance and monitoring result methane oxygen two parameter alarms accurately and reliably.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of methane oxygen two parameter alarms comprise housing, it is characterized in that; Dividing plate is installed in the housing; Dividing plate top is epicoele, and the lower partition is a cavity of resorption, and electrochemistry oxygen gas sensor, thermocatalysis methane transducer, hummer and circuit board are installed in the epicoele; Be provided with battery compartment in the cavity of resorption; The front panel of housing is provided with warning diode, LCDs and facial mask switch, and said electrochemistry oxygen gas sensor, thermocatalysis methane transducer, warning diode, LCDs and facial mask switch are connected with circuit board respectively, and housing is provided with transom and methane is demarcated valve.
The alarm of the utility model under coal mine, there be continuous monitoring methane and concentration of oxygen in the working environment of inflammable and explosive inflammable gas potpourri in chemical metallurgy, environmental protection scene etc., and when transfiniting, carry out sound and light alarm.It is little, in light weight, simple to operation, easy to maintenance that instrument has a volume, and instrument adopts the film touch-switch, good seal performance, accurately and reliably.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Below in conjunction with embodiment and accompanying drawing the utility model is done further explain.
Embodiment
With reference to figure 1 and Fig. 2; The methane oxygen two parameter alarms of the utility model comprise housing 1, and dividing plate 2 is installed in the housing 1, and dividing plate 2 tops are epicoele; Dividing plate 2 bottoms are cavity of resorption; Electrochemistry oxygen gas sensor 3, thermocatalysis methane transducer 4, hummer 5 and circuit board 7 are installed in the epicoele, are provided with battery compartment 6 in the cavity of resorption, the front panel of housing 1 is provided with warning diode 10, LCDs 8 and facial mask switch 12; Said electrochemistry oxygen gas sensor 3, thermocatalysis methane transducer 4, warning diode 10, LCDs 8 are connected with circuit board 7 respectively with facial mask switch 12, and housing 1 is provided with transom 11 and demarcates valve 9 with methane.
When instrument places the environment that has methane gas; Methane gas gets into air chamber through the transom 11 of instrument; Thermocatalysis methane transducer surface in the air chamber produces flameless burning; Its resistance increases, the Wheatstone bridge out of trim output voltage signal that thermocatalysis methane transducer and resistance are formed, and the size of voltage signal is directly proportional with methane concentration.Signal A/D converter on the input circuit plate after linear amplifier amplifies converts digital signal into; Handle through the microprocessor data on the circuit board; Demonstrate methane concentration by LCDs, after the concentration of methane surpassed the alarm set point of setting, instrument sent the sound and light alarm signal.
When instrument is used for the oxygen of Measurement of Air, the electrochemistry oxygen gas sensor with diffusion way directly with environment in gas reaction, the voltage signal of generation linear change.Signal A/D converter on the input circuit plate after linear amplifier amplifies converts digital signal into; Handle through the microprocessor data on the circuit board; Demonstrate oxygen concentration by LCDs, be lower than the alarm set point of setting when oxygen concentration after, instrument sends the sound and light alarm signal.
When methane and concentration of oxygen surpassed simultaneously or be lower than the safety value of setting, instrument sent sound, visual alarm, and the value of reading of Alternation Display methane and oxygen.Instrument has anti-high concentration methane impact function, when instrument detected extraneous methane concentration in continuous 30 seconds more than or equal to 4.00% the time, cuts off the power supply and the warning of catalysis element automatically.
Employed electronic devices and components are commercially available known product in the alarm of the utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the technique effect of the utility model.
