Summary of the invention
In order to overcome deficiency existing in prior art, provide a kind of Real-Time Monitoring, detect accurately, reduce the wall-attaching type checkout gear of air draft cost, this checkout gear precisely can detect gas emission in underground coal mine complex environment.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
The wall-attaching type checkout gear of a kind of tunnel internal face gas emission, comprise the stuffing box of bottomless inner hollow, A type watt sensor is provided with in described stuffing box, Type B firedamp sensor, temperature pick up, humidity sensor, pressure sensor, power supply and Wireless Telecom Equipment, described stuffing box is provided with digital display panel, swing type air door, antenna and scavenger fan, described A type watt sensor, Type B firedamp sensor, temperature pick up, humidity sensor, pressure sensor, digital display panel is connected with Wireless Telecom Equipment respectively with antenna, described Wireless Telecom Equipment is connected with power supply.
The bottomless one side of described stuffing box can be bolted on rib, and with the gap between composite polyurethane material sealing stuffing box and rib.
Described digital display panel can from Real Time Observation gas density, temperature, humidity, pressure and other parameters outside stuffing box.
Described A type firedamp sensor and Type B firedamp sensor can be any two kinds of combinations of optics, catalytic combustion, electrochemistry or semiconductor firedamp sensor.
The Signal transmissions that Wireless Telecom Equipment gathers by described antenna is to control centre.
Gas in stuffing box is discharged from swing type air door by described scavenger fan timing, and changes fresh air.
Described Wireless Telecom Equipment is for detecting data receiver, process and transmission.
The beneficial effect that the present invention is compared with prior art had is:
Be arranged on rib, detect wall gas emission, can be combined fan delivery with the existing gas indicator in tunnel, reach the object of safety in production and energy-saving and emission-reduction.Wall-attaching type wall gas emission checkout equipment can measure coal seam wall variation ofgas density situation in setting-up time scope periodically and obtain Gas intensity, and can wireless transmission institute image data, accurately record rib Gas intensity under calm condition; Thus the real-time detection realized wall gas density, provide reliable basis for calculating downhole production Air Quantity Required.
