Background technology
Coal production is due to the impact by objective natural conditions, and its fixed equipment failure rate is far away higher than other commercial units.Ventilation blower is one of vital mining equipment in coal production, which is responsible to mine conveying air, to reduce harmful gas concentration and to take away the coal dust of suspension, mine operation workman safety, reliable, good condition of work are provided, the personal safety of its property relationship to staff and the economy of equipment operation, the hydraulic performance decline of ventilation blower, fault are the one of the main reasons causing gas explosion.Therefore, only have rationally to operational monitoring and the later maintenance of ventilation blower, the economic benefit of guarantee coal mine downhole safety and raising working environment at coal mines and lifting ventilation blower and work efficiency.In coalmine ventilation road, measurement environment is severe, its be mainly manifested in distinguished and admirable in be mingled with a large amount of impurity, dust, steam, and airflow direction is unstable, this just cause some current coalmine ventilation flow-measuring methods directly not measure flow or its measuring error larger.At present, the vent flow of the actual use of mine is measured and is usually adopted anemometer mensuration, piezometric tube mensuration, differential manometer mensuration etc.
Anemometer mensuration, require that ventilation measuring point selects somewhere air-flow between drag regulator to ventilation blower the most steady, on the cross section that eddy current is minimum, but the layout in on-the-spot air channel be often difficult to selection have sufficient length, more uniform wind speed field Measure section like this, thus make measurement result have very large error.Staff needs to enter in air channel in addition, not only affects measurement accuracy, and working condition is very poor, and holding time is also longer.Meanwhile, this method also cannot carry out on-line monitoring.
In piezometric tube and differential manometer mensuration, pitot tube itself has stronger susceptibility to airflow direction, often because installing inaccurate or loosely departing from wind direction by distinguished and admirable blowing, the accuracy that impact is measured; Moreover carry out in ventiduct due to the measurement of the mine blast volume to reality, and condition is quite severe in the mine air channel of reality, a large amount of impurity, dust, steam is mingled with in distinguished and admirable, easily cause the problems such as pressure tap blocking, thus causing flowmeter to lose efficacy, accuracy and the reliability of measurement can not be guaranteed.
In view of this existing various measuring technique is in the process measured, and there is respective drawback, under the rugged environment of air channel, cannot carry out long-time, effectively and accurately work.Therefore need effectively to improve existing air channel vent flow measuring technique.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides air channel, a kind of colliery vent flow on-line monitoring system, native system can realize multidraw, exports in real time, make measurement result more accurately, reliable, be convenient to monitoring.
For achieving the above object, the technical solution used in the present invention is: air channel, a kind of colliery vent flow on-line monitoring system, comprise data acquisition system (DAS) and data handling system, data acquisition system (DAS) is electrically connected with data handling system, data handling system is made up of data processor and display device, data processor and display device electrical connection, data acquisition system (DAS) comprises solid bearing, torque sensor, streams object, upper rail plate and lower slider guide rail; Solid bearing top and bottom are connected with upper rail plate and lower slider slide respectively, stream object and are arranged on solid bearing, and torque sensor is arranged on and streams on object, and torque sensor is electrically connected with data processor.
Move in air channel, colliery for ease of solid bearing, solid bearing top and bottom are connected with upper rail plate and lower slider slide respectively by upper sliding sleeve, lower slipping sleeve.
Rotate on solid bearing for the ease of streaming object, solid bearing is provided with shaft sleeve, stream object and be connected with solid bearing by shaft sleeve.
In order to further expand multimetering, streaming object has three, and each object that streams is connected with solid bearing respectively by a shaft sleeve.
The invention has the beneficial effects as follows: 1, the present invention streams by solid bearing axially multiple the acting force that fluid flowing that object measures axially diverse location place respectively produces, and the acting force that the fluid flowing of streaming diverse location place in object traverse measurement level in the horizontal direction produces, achieve multiple spot, efficiently and accurately at the flow velocity measuring each position fluid in air channel, whole colliery, thus make air channel, the colliery vent flow accurate and effective more that records.
2, be not subject to ventiduct tunnel structure to arrange restriction in measuring process, in distinguished and admirable, be not mingled with a large amount of impurity, dust, influence of moisture, also do not affect by factors such as airflow direction instability, make the result of measurement more accurately reliable.
3, be install in the axial direction owing to streaming object, so effectively avoid the impact that the moment that produces because of Action of Gravity Field brings, make result more accurate.
4, measuring system part of the present invention be convenient to install, component is not easy to wear, blocking and damage, thus can be long-term on-line measurement is carried out to coal mine ventilation flow, reach saving economically.
5, the present invention measures air channel, colliery vent flow by mechanical mechanism, the parameters of fluid except flow velocity, density is not related in computation process, thus the impact that is subject in transfer process of measurement result is less, makes the result that obtains more accurately and reliably.
6, have display device in the present invention, by transmission line can be directly perceived, instant, online by coalmine ventilation flow indication out, facilitate the monitoring of staff.
