Abstract
The utility model relates to the semi-automatic portable gas detector of a kind of extension type, formed by feeler lever collector, negative-pressure power system and gas surveying device, the portable watt of inspection instrument that the utility model is open with respect to traditional measurement port, enclosed measuring equipment not only can pass through the longer-distance gas density of gas measurement by sound, and can prevent that thereby portable watt of inspection instrument from detecting mouthful gas density at place and being diluted and causing measured value lower than actual value, avoid mistake to survey wrong report; And with respect to traditional optical watt inspection instrument, thering is measuring speed faster and more easily, the digital display screen of being furnished with and small negative pressure sampling instrument can make to measure and be completed at short notice by single; The each part detachable of the utility model, easy to carry, can realize quick, Measurement accuracy distant location gas density.The utility model structure is succinct, measures convenient and swiftly, can in current actual measurement, use.
Description
Technical field
The utility model relates to mine gas prevention and control field Mine Methane and measures verifying attachment, and concrete is the semi-automatic portable gas detector of a kind of extension type.
Background technology
In mine production and process of construction, Gas is located all can have in roadway surrounding rock, coal seam and goaf etc.When the gas of gushing out gathers finite concentration somewhere, may cause the generation of accident, the variation of therefore monitoring gas density is most important.Cannot realize telemeasurement for traditional portable gas detector, cannot ensure to adopt gas feeler lever to give vent to anger the gas density of port not by distinguished and admirable dilution simultaneously, thereby affect gas density actual value, and optics gas detector, complex operation step, measuring period is long, thus be necessary to develop a kind of can be fast, the novel portable gas detector of Measurement accuracy distant location gas density, the in-site measurement analysis that facilitates the daily gas monitor of mine and scientific research institution to need.
Summary of the invention
The purpose of this utility model is to provide the semi-automatic portable gas detector of a kind of extension type, and the utility model can be realized compared with the Quick Measurement of long distance gas concentration.
The technical solution of the utility model is as follows: the semi-automatic portable gas detector of a kind of extension type, comprise feeler lever collector, negative-pressure power system and gas surveying device, feeler lever collector comprises extension type gas feeler lever (1), pagoda head (2) forms, negative-pressure power system comprises PU flexible pipe (3), intrinsic safe explosion-proof type negative-pressure gas sampling instrument (4), switch (5), connecting hose (6), gas surveying device comprises breather cheek valve (7), gas detector (8), one-way exhaust valve (9), switch (10), display screen (11), scalable gas feeler lever (1) is provided with pagoda head (2), scalable gas feeler lever (1) is connected with intrinsic safe explosion-proof type negative-pressure gas sampling instrument (4) with PU flexible pipe (3) by pagoda head (2), intrinsic safe explosion-proof type negative-pressure gas sampling instrument (4) is provided with switch (5), gas detector (8) is provided with breather cheek valve (7), one-way exhaust valve (9), switch (10), display screen (11), intrinsic safe explosion-proof type negative-pressure gas sampling instrument (4) is connected with breather cheek valve (7) port of gas detector (8) by PU flexible pipe (6).
The portable watt of inspection instrument that the utility model is open with respect to traditional measurement port, enclosed measuring equipment not only can pass through the longer-distance gas density of gas measurement by sound, and can prevent that thereby portable watt of inspection instrument from detecting mouthful gas density at place and being diluted and causing measured value lower than actual value, avoid mistake to survey wrong report; And with respect to traditional optical watt inspection instrument, thering is measuring speed faster and more easily, the digital display screen of being furnished with and small negative pressure sampling instrument can make to measure and be completed at short notice by single; The each part detachable of the utility model, easy to carry, can realize quick, Measurement accuracy distant location gas density.The utility model structure is succinct, measures convenient and swiftly, can in current actual measurement, use.。
