A device and method for improving the reliability of mine gas pipeline fire detectors

Abstract

The invention relates to detection of gas deflagration instant ultraviolet radiation and infrared radiation and fire alarm signal output, in particular to a device and a method capable of prompting reliability of a mining gas pipeline fire detector. The device capable of prompting the reliability of the mining gas pipeline fire detector is characterized by comprising a detector shell body. A singlechip, an ultraviolet sensitive element, an infrared sensitive element and a quartz window are designed in the interior of the detector shell body. An infrared receiving pipe and an infrared emitting pipe are respectively arranged on the inner side and the outer side of the quartz window. The ultraviolet sensitive element, the infrared sensitive element, the infrared receiving pipe and the infrared emitting pipe are respectively in electric connection with the singlechip. The infrared emitting pipe is controlled to emit infrared lights inside the quartz window by the singlechip. The infrared lights which are emitted by the infrared emitting pipe and received by the infrared receiving pipe are detected by the singlechip to confirm translucency of the quartz window. If pollution is larger than an alarm threshold value, pollution alerting signals are given immediately. Alarm threshold values of the ultraviolet sensitive element and the infrared sensitive element are set by the singlechip. Fire alarm signals are given out through detection of signal amplitudes of ultraviolet of 0.2 Mum and infrared of 2.7 Mum, wherein the ultraviolet of 0.2 Mum and the infrared of 2.7 Mum are produced by external gas combustion. The device capable of prompting the reliability of the mining gas pipeline fire detector is used for quickly detecting the a fire which possibly appears in the coal mine environment or the deflagration phenomenon which appears in a gas pipeline and preventing damage to coal mines and personal safety, wherein the damage is caused by the fire or the gas deflagration.

Description

technical field [0001] The invention relates to the detection of ultraviolet and infrared radiation at the instant of gas deflagration and the output of fire alarm signals, in particular to a device and method for improving the reliability of mine gas pipeline fire detectors, which are used to quickly detect possible fires or gas in coal mine environments The deflagration phenomenon in the pipeline can prevent fire or gas deflagration from causing damage to coal mines and personal safety. Background technique [0002] In recent years, serious and extraordinarily serious gas explosion accidents have occurred frequently in our country, and great attention has been paid to this at home and abroad. Preventing the occurrence of gas accidents has become the primary task to ensure safe production in coal mines. At the same time, as a high-quality, high-heat, clean and convenient "green" energy, the importance of its development is beginning to be recognized by people. [0003] In ...

Problems solved by technology

[0006] The traditional underground explosion-proof methods used in my country are passive explosion-proof methods such as explosion-proof rock powder shed and explosion-proof water shed. Practice research has proved that when the gas and coal dust explosion intensity is very weak, the passive explosion-proof measures fail, that is, they cannot prevent the explosion flame. At the same time, due to ventilation and evaporation, coal dust pollution, damp agglomeration and other reasons during on-site use, it is difficult to achieve the expected explosion-proof effect
