Description
Technical field
The utility model relates to the coal mine safety monitoring device.
Background technology
Along with science and technology development and progress, coal mine safety monitoring, supervisory system have obtained general promotion and application, according to relevant regulation and requirement, sensors such as the methane in coal mine safety monitoring, the supervisory system, oxygen, carbon monoxide, temperature, wind speed pressure must carry out 7-10 days daily calibration, can guarantee its value accurately and reliably, operate as normal.But the means and the method for calibrating these sensors now are very immature.As when calibrating methane transducer, common way is that the relevant personnel carry a bladders or an air bag (wherein having filled calibrating gas), cooperates with a gas meter again, and calibration operation is removed to carry out in the scene under the coal mine.The shortcoming of this way is that hand is pinched bladders and extruded gas and make flow very unstable, and the gas that fills in bladders or the air bag very little, can not guarantee according to the calibration rules to methane transducer conscientiously, correct calibration finishes up hill and dale.Now sensors such as temperature, wind speed, pressure are still lacked effective calibration steps and means in addition.
Summary of the invention
The purpose of this utility model provides a kind of coal mine safety monitoring pick up calibration device, and this cover calibrating installation not only can be used for the existing various sensors of down-hole field calibration in each large, medium and small colliery of China.Also be applicable to industries such as petrochemical industry, iron and steel, the various sensors that have monitoring, supervisory system for these industries now provide effective calibration means of cover and a method, to guarantee various sensor values accurately and reliably, can work for a long time, thereby the safety in production that guarantees colliery and other industry is normally carried out.
For achieving the above object, the utility model by the following technical solutions:
A kind of coal mine safety monitoring pick up calibration device, it has gas cylinder, glass rotameter, described gas cylinder has at least one, these gas cylinders connect a multiport valve respectively with high-pressure rubber pipe, the venthole of this multiport valve connects the air admission hole of glass rotameter with high-pressure rubber pipe, the venthole of this glass rotameter is connected with a calibration cover with high-pressure rubber pipe, and this calibration is covered with the air admission hole of gas sensor to be calibrated and is connected.
Described each gas cylinder has cylinder valve, reduction valve and tensimeter.
Be connected with reduction valve on the pipeline of the high-pressure rubber pipe between the venthole of described multiport valve and the air admission hole of glass rotameter.
Be filled with the calibrating gas or the calibration gas of clean air and variety classes, variable concentrations in described each gas cylinder respectively.
The calibrating gas or the calibration gas of methane, oxygen, carbon monoxide are housed respectively in described each gas cylinder.
Described gas cylinder, glass rotameter, gas sensor, high-pressure rubber pipe, four-way valve, calibration cover all are contained in the chest.
The utility model has following positive beneficial effect:
Lack effective calibration steps and this defective of means at the various sensors in the coal mine safety monitoring supervisory system, we have invented a kind of calibrating installation, it is carrier that this calibrating installation can be carried on the back leather trunk or the senior aluminium alloy case (hereinafter to be referred as " chest ") that can carry on the arm with one, chest is equipped with at least one aluminium alloy gas cylinder of the 0.3 liter not isometric gas cylinder of other material (also), be filled with the calibrating gas or the calibration gas of clean air and variable concentrations in the bottle, gas cylinder and two-port valve or multiport valve, gas meter, the calibration cover waits and has constituted a complete air-channel system, they all are contained in the chest, when needing calibrating sensors, carry this chest and just can remove calibrating sensors to scene under the coal mine.If need the calibration methane transducer, chest is that the gas cylinder of methane calibration gas is put in the chest being filled with the methane calibrating gas so, and methane transducer is removed to calibrate in the scene that is carried under the coal mine; If need the calibration carbon monoxide transducer, then the carbon monoxide calibrating gas gas cylinder that clean air and several variable concentrations are housed is put in the chest, just can arrive under the coal mine and calibrate carbon monoxide transducer.Same reason, the cylinder filling in this chest has the calibrating gas of what gas, just can correctly calibrate which type of gas sensor according to the calibration rules to production operation is on-the-spot.Above-mentioned is the basic configuration of this cover calibrating installation, just can arrive the existing various sensors of production operation field calibration if be equipped with standard thermometer, standard electronic wind gage, master gauge and rain glass etc. with measurement verification certificate again.This cover calibrating installation not only can be used for the existing various sensors of down-hole field calibration in each large, medium and small colliery of China, also be applicable to industries such as petrochemical industry, iron and steel, the various sensors that have monitoring, supervisory system for these industries now provide effective calibration means of cover and a method, with guarantee various sensor values accurately and reliably, can work for a long time, thereby the safety in production that guarantees colliery and other industry is normally carried out.
