Description
Technical field
The utility model relates to a kind of clothes, specifically is the clothes that gas is surveyed in a kind of down-hole, belongs to the gas monitor technical field.
Background technology
Gas is a kind of gas general designation; Can be divided into liquefied petroleum gas and natural gas, coal gas three major types, in recent years in the Coal Production process owing to the gas density major accident that causes that transfinites happens occasionally, and each accident all can cause any property loss and casualties; Bring massive losses to national economy; Bring heavy disaster for the family of casualty, so, extremely urgent for the fire damp concentration monitoring.
In the prior art, all rely on fixing monitoring equipment, because the installation site of monitoring equipment is comparatively fixing for the monitoring of gas density; Monitoring range is little; Accuracy is low, and cost is higher, and installation and maintenance are loaded down with trivial details; The function of gas monitor early warning can not be played effectively, or the effect of prevention caution can not be in time played.
Summary of the invention
Problem to above-mentioned prior art existence; The clothes that the utility model provides a kind of down-hole to survey gas, the form that adopts gas sensor and clothes to mutually combine can be monitored gas density accurately and efficiently; In time send early warning signal, the danger that prevention gas explosion produces.
To achieve these goals, the utility model is realized through following technical scheme: the clothes of gas is surveyed in a kind of down-hole, comprises lead, clothes inner bag, CONCEAL ZIPPER and battery, also comprises using gas sensor head and electronic control module; The clothes inner bag is opened in the inboard of the front part of a Chinese robe or jacket, and CONCEAL ZIPPER is opened in the opening part of clothes inner bag, and electronic control module and battery are positioned in the clothes inner bag, and the using gas sensor head is connected with electronic control module through lead.
Electronic control module is made up of gas sensor, contactless electronic beam switch, siren warning circuit and loudspeaker.
The beneficial effect of the utility model is: simple in structure, with low cost, can carry, and can monitor gas density accurately and efficiently, in time send early warning signal, and make things convenient for installation and maintenance and use.

Fig. 3 is the circuit theory diagrams of electronic-controlled installation in the utility model.
Among the figure: 1, gas sensor, 2, lead, 3, the clothes inner bag, 4, CONCEAL ZIPPER, 5, electronic control module, 6, battery.
The specific embodiment
To combine accompanying drawing that the utility model is further specified below.
As depicted in figs. 1 and 2, the clothes of gas is surveyed in a kind of down-hole, comprises lead 2, clothes inner bag 3, CONCEAL ZIPPER 4 and battery 6, also comprises using gas sensor head 1 and electronic control module 5; Clothes inner bag 3 is opened in the inboard of the front part of a Chinese robe or jacket, and CONCEAL ZIPPER 4 is opened in the opening part of clothes inner bag 3, and electronic control module 5 is positioned in the clothes inner bag 3 with battery 6, and using gas sensor head 1 is connected with electronic control module 5 through lead 2.
The course of work of the utility model is:
When environment does not have gas or gas density when low, the A-B electrode resistance R of QN-N5 is very big, then IGCT VS because of the trigger electrode current potential is very low can not conducting; When gas density raise, then R reduced, when gas density is elevated to above safety standard; A-B interpolar conductance increases rapidly, and R resistance reduces rapidly, when R sliding contact voltage during greater than 0.7V; The IGCT VS conducting that is triggered, 3 pin of LC179 are connected negative supply, and 4 pin output signal drives loudspeaker; Send police car electric whistle sound, thereby reach the purpose of prevention gas exceeding limit early warning.
By the upper garment of normal operation manufacturing clothes, leave the space that holds electronic-controlled installation 5 and battery 6 in front part of a Chinese robe or jacket inboard, promptly the clothes inner bag 3; And seal with CONCEAL ZIPPER 4; Battery 6 is 4.5V lithium batteries, and cell voltage is no more than 4.2V, has power switch; Usually the time spent can not turn off, and electronic-controlled installation 5 can also embed in the coat-sleeve or other position.
The wiring board of electronic-controlled installation 5, the encapsulation of battery 6 usefulness thermoplastic tube have water-proof function, connect with lead 2 between wiring board and the battery 6, can load and unload.Battery 6 can take off charging, when underground work, can open switch, and when fire damp concentration raise above safety standard, electronic-controlled installation 5 sent police car electric whistle sound, thereby reaches the purpose of prevention gas exceeding limit.
As shown in Figure 3, the gas sensor in the electronic control module 5 can adopt QM-15 type heater-type, and loudspeaker can be selected YD58-1 type, 0.25W dynamic speaker for use; C selects the 47F electrolytic capacitor for use, and A, B are for measuring level, and it adds thermoae extremely separated from one another with measurement; Heater strip does not contact with gas sensitive, and that has avoided measurement loop and heating circuit influences each other stable performance, good reliability; Heating voltage is AC or DC5+0.2, response time＜10s, recovery time＜30s.
LC179 is three simulated sound warning special ICs, and it adopts biserial octal straight cutting plastics to encapsulate firmly, and circuit reliability is high; Inner integrated power amplifier can directly drive the loudspeaker sounding; Can produce three kinds of different simulation alarm sounds, the 1st, 2 pin of LC179 are external oscillation resistance device end, and the resistance of increase and decrease institute termination resistor can change the sounding tone; The 3rd pin is a negative power end; The 4th pin is an audio output; The 5th pin is a positive power source terminal; 6th, 7 pin are empty foot; The 8th pin is a sound collecting end, when it when " unsettled ", can produce simulation police car electric whistle sound, when it connects power positive end, can produce simulation fire fighting truck electric whistle sound, when it connects power supply negative terminal, can produce simulation ambulance electric whistle sound.
The major parameter of LC179 is: operating voltage range is 3～4.5V, operating current＜150A, and maximum output current can reach 150mA, and operating temperature range is-10～60C.On business suit, adorning electronic installation, 1. is loudspeaker, so that send alarm sound, 2. is the button cell on power supply road, 3. is the electronic module of realizing function, and wherein in order to reduce the space, what components and parts were used is the paster components and parts.4. be the gas sensor selection QM-15 type heater-type in the circuit.5. be contactor, the time spent can not turned off power supply.
Gas sensor in the electronic control module 5 has very high sensitivity for light concentration gas; Using gas sensor head 1 has olfactory function; Can detect gas density automatically, in case gas exceeding limit, electronic control module 5 can be reported to the police automatically; Take to take out earlier the principle of afterwards adopting then, can prevent the generation of gas explosion accident.
