Description
Technical field
The utility model relates to a kind of mine ventilation system ventilation parameter measurement device, more precisely a kind of mine special explosion venting parameter on-line determination device.
Background technology
Mine ventilation system is called as " heart " and " artery " of mine, and the object of mine ventilation is for underground work personnel provide fresh air, can discharge toxic and harmful in time, ensures the working environment that down-hole is good, safe.At present, China's coal-mine is along with the continuous extension of development, down-hole required airflow certainly will improve, part coal mine evacuation working face and connection roadway arrange more, ventilation system more sophisticated, cause the large lane of ventilation system return air and unreasonable with wind point allocation of the amount of air, some tunnel wind speed exceed the requirement of " safety regulations in coal mine ", even occur the distinguished and admirable disorderly phenomenon of local ventilation system.Based on this present situation, people can adopt the ventilation parameter of a kind of device or each split of equipment Real-Time Monitoring mine, mainly comprise the atm difference and dry humidity etc. of tunnel wind speed and air quantity, intersection of branch.Simultaneously, dust concentration size has vital effect to the healthy and safe of underground operators, also the relation of this interwoveness is there is with dash parameter, but administrative staff neglect the monitoring to dust concentration sometimes, dust concentration size under what conveniently people can be real-time check mine, can produce a kind of ventilation parameter measurement device with dust concentration Real-Time Monitoring.
Existing mine ventilation parameter monitor device function singleness, can only monitor a parameter, and lacks protective structures setting.
Utility model content
The purpose of this utility model to provide a kind of mine special explosion venting parameter on-line determination device, solves the problem of current mine ventilation system ventilation basic parameter real time on-line monitoring.
For solving the problems of the technologies described above, this mine special explosion venting parameter on-line determination device, comprise air velocity transducer, sensor of dust concentration, differential pressure pickup, wet-and-dry-bulb thermometer, fixed connecting rod, explosion-proof layer, signal processor, display terminal and power line, it is characterized in that: described air velocity transducer, sensor of dust concentration, differential pressure pickup and wet-and-dry-bulb thermometer are fixed on inside explosion-proof layer, described explosion-proof layer is formed by the antistatic metal material manufacture that structure comparison is hard, air velocity transducer, sensor of dust concentration, the signal receiving end of differential pressure pickup and wet-and-dry-bulb thermometer is arranged in outside explosion-proof layer, and respectively by wire, Received signal strength is transferred to signal processor, connected by wire between signal processor and display terminal.
In tunnel, situation is complicated, and particularly the transport of equipment is passed through, and likely scratching is to air velocity transducer, sensor of dust concentration, differential pressure pickup and wet-and-dry-bulb thermometer etc., and critical piece is placed in explosion-proof layer by the design, can avoid physical damage; And the design of anlistatig metal material can prevent the generation of electrostatic, avoid the generation being caused accident by electrostatic.
As optimization, described explosion-proof layer is fixed by fixed connecting rod and is hung on the inside ceiling panel of tunnel.Design like this, the wind speed on upper strata comparatively lower floor is fast, can more precise and high efficiency record every data, and can avoid in physical damage as far as possible.
The data that air velocity transducer, sensor of dust concentration, differential pressure pickup and wet-and-dry-bulb thermometer record through wire transmission to signal processor, through the process of signal processor, present over the display through wire transmission to display terminal, a display terminal can connect the input of one or more data, display terminal also can store data, in order to checking later.
This mine special explosion venting parameter on-line determination device have measure simultaneously many index, conserve space, simple and practical and can be explosion-proof feature, be widely used in the real-time monitoring of the ventilation parameter in the underworkings of ore deposit.
