Miner's lamp with digital display carbon monoxide concentration detection and alarm function

Abstract

The invention discloses a mine lamp with functions of displaying carbon monoxide concentration in a digitized way, detecting the carbon monoxide concentration and alarming, which comprises a digital display alarm device, an overhead mine lamp and a carbon monoxide gas detection sensor part, wherein the carbon monoxide gas detection sensor part is arranged on the overhead mine lamp or the digital display alarm device; the overhead mine lamp is connected with the digital display alarm device by a cable; the digital display alarm device is provided with an intelligent control and memory chip with power-off memory function, an analog to digital converter and a battery; the carbon monoxide gas detection sensor part is provided with a detection chamber which is internally provided with a probe; a gas inlet hole is arranged in front of the detection chamber; and a vent hole is positioned on the top of the detection chamber. The product of the invention is more convenient to carry and use and low in whole equipment cost, and has the function of intelligent data analysis.

Description

technical field [0001] The invention relates to the field of industrial and mining detection equipment, in particular to an intelligent miner's lamp for detecting and alarming the concentration of carbon monoxide. Background technique [0002] Carbon monoxide is a widespread harmful gas in coal mining. The carbon monoxide measuring (alarm) device is used to detect the carbon monoxide content in the mining environment during the coal mining process in my country, and generates an alarm signal when the concentration exceeds the preset alarm concentration. The "MT703-2008 Portable Electrochemical Carbon Monoxide Detector for Coal Mine" standard clearly defines this type of product. The existing carbon monoxide measuring (alarm) device is a kind of expensive detection instrument, which does not have the function of automatically memorizing data and does not have the function of intelligent analysis of data when the power is cut off. The miner's lamp is a must-have assembly for...

Problems solved by technology

[0003] The two products introduced above are both single-function products in practical applications. If you want to meet both the lighting function and the carbon monoxide detection and alarm function, you must carry these two products, which not only increases the inconvenience of carrying sex

Moreover, since both the carbon monoxide detector and the miner's lamp are portable electronic devices, they all need battery power supply, power supply management, light indication, and protective shell and other components. They are used separately, which increases the use cost and maintenance cost of the equipment, which is not conducive to the promotion and use of the product.

Moreover, the detection head of the existing carbon monoxide measuring (alarm) device is directly installed in the instrument shell, the circuit layout is unreasonable, the measurement data is inaccurate, and it is easily disturbed by environmental dust and airflow
