Description
Technical field
The utility model belongs to optical detecting instrument, is specifically related to a kind of Methane determination intelligence sensor of convenient sampling.
Background technology
At present, coal industry remains high risk industries, and high gas and Gas Outburst mine account for China's coal-mine about half, so the research and development coal mine safety apparatus becomes China's Major Scientific Research Projects.When measuring methane content, need to then bring to ground from well sampling and detect in the past, this detection mode speed is slow, poor accuracy.Application number a kind of digital optical interference methane determining device that has been 201120083121.9 patent disclosure, it comprises shell, light path system and projection imaging system in the enclosure and that be communicated with inlet channel is set.This analyzer can the field survey methane content and will be detected data and directly be shown by charactron, and its advantage is that detection speed is fast, degree of accuracy is high, but it can not sample to gas automatically, needs manually-operated.
Application number a kind of light interference type methane analyzer that has been 201020527858.0 patent disclosure, it comprises interference spectroscope, absorption tube, air-breathing ball and proofed sleeve.The two ends of described absorption tube by proofed sleeve respectively with the gas specimen chamber be connected ball and be connected, placed the absorbing agent that is used for the dry and contaminant filter of gas in the inner chamber of described absorption tube.The advantage of this patent is, when this apparatus measures, described absorption tube can be removed various foreign gases and the water vapor in the gas to be measured effectively, thereby reduced the corrosion and damage to methane analyzer, its weak point is that described air-breathing ball is arranged at the end of absorption tube, survey crew will be held air-breathing ball and enters into gaseous environment and carry out artificial sample operation during work, and this is just so that survey crew may be subject to the threat of poisonous gas.
For the deficiencies in the prior art, the utility model is innovated the Methane determination instrument and is improved, and makes survey crew safer when measuring methane gas content, convenient and quick.
The utility model content
For the deficiencies in the prior art, this practicality provides a kind of Methane determination intelligence sensor of convenient sampling, the Methane determination intelligence sensor of this convenience sampling not only can gather the gas sample automatically, but also can be positioned at the harmful gas of different depth by the length measurement of regulating sampling pipe, thereby guaranteed the safety of survey crew.
The Methane determination intelligence sensor of convenient sampling, comprise housing, light path system and sampling apparatus, be provided with air plenum and gas production specimen chamber in the described light path system, described sampling apparatus is arranged on the housing and with the gas production specimen chamber and is communicated with, be provided with the sampling pipe that is communicated with the gas production specimen chamber on the described sampling apparatus, one end of described sampling pipe is fixed on the housing, and the other end stretches out outside the housing.
Further, described sampling pipe is for can prolong sampling pipe, and the described front end that prolongs sampling pipe has the latch closure for the continued access sampling pipe.
Further, the described front end that prolongs sampling pipe also is provided with dirt-proof boot.
Further, be provided with minipump on the described sampling apparatus, described minipump is controlled by time switch.
The beneficial effects of the utility model: the Methane determination intelligence sensor of convenient sampling of the present utility model, comprise housing, light path system and sampling apparatus, be provided with air plenum and gas production specimen chamber in the described light path system, described sampling apparatus is arranged on the housing and with the gas production specimen chamber and is communicated with, be provided with the sampling pipe that is communicated with the gas production specimen chamber on the described sampling apparatus, one end of described sampling pipe is fixed on the housing, and the other end stretches out outside the housing.Described sampling pipe is for can prolong sampling pipe, and the described front end that prolongs sampling pipe has the latch closure for the continued access sampling pipe.Sampling pipe can be prolonged so that survey crew needn't enter into the harmful gas environment in person when measuring harmful gas by arranging at the Methane determination intelligence sensor, thereby so that surveying work is safer.
In addition, at described sampling apparatus the minipump of being controlled by time switch is set, can realizes the sampling of surveying instrument timing automatic, thereby further reduced the working strength of survey crew.
Description of drawings
