Abstract
The utility model provides a mine ventilation and gas safety monitoring system, relates to the technical field of mine ventilation and gas safety discharge, and is mainly applied to underground coal mine ventilation and gas safety discharge. At present, mine ventilation takes up the heavy responsibility for transporting fresh air to a mine, discharging dust and dirty airflows and draining gas, and reasonable air volumes in roadways can affect the whole mine production and safety tremendously, therefore, a set of a complete monitoring system is required to be established to ensure that ventilation volumes in branch roadways can meet the requirements for safe production and reliable operation. The mine ventilation and gas safety monitoring system aims to monitor the ventilation of underground roadways and gas density correspondingly, nonstandard air volumes in the underground roadways or exceeding gas density are or is controlled correspondingly, large potential safety hazards are avoided, an alarm can be given for an emergency timely, the working environment of an underground worker is improved, the working efficiency of the worker is increased, and the monitoring system has the advantages of low cost, convenience in maintenance, small size and the like.
Description
Technical field
The utility model relates to a kind of mine ventilation and gas safety monitoring system, is mainly used in the safety dumping of monitoring underground coal mine mine ventilation and gas, belongs to the mine ventilation field
Background technology
At present mine ventilation is being undertaken to delivered downhole fresh air, the important task of discharging dust, dirty air-flow and drawing out methane.Rational air quantity in roadway, will form the production and safety of whole mine and produce tremendous influence.Therefore, need set up the monitoring system of a set of perfect in shape and function, to guarantee that in each branch's roadway, the ventilation volume size meets safety in production, reliable.
Summary of the invention
The purpose of this utility model is alarm is monitored and reached to underworkings ventilation situation and gas density, avoids causing mine ventilation and the gas safety monitoring system of large-scale potential safety hazard.
Technical solution
The utility model comprises: electrical source of power, relay, firedamp sensor, temperature pick up, air velocity transducer, single-chip microcomputer, alarm; The output of firedamp sensor, temperature pick up, air velocity transducer is connected with the input of single-chip microcomputer respectively, and the output of single-chip microcomputer is connected with the input of alarm, relay respectively, and relay output end is connected with electrical source of power.
The utlity model has following characteristics:
1, its sensitivity of this new device is higher, and reaction can effectively be avoided the generation of disaster accident in time, improves underground labour's working environment and improves workman's operating efficiency.
2, this new device volume is little, and cost is low the advantage such as is convenient to safeguard, volume is little
3, this new device automaticity is higher, can effectively alleviate the workload of person skilled, improves relevant work efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model site work state diagram;
Fig. 2 the utility model operating principle block diagram.
The specific embodiment
The output of the utility model firedamp sensor 3, temperature pick up 4, air velocity transducer 5 is connected with the input of single-chip microcomputer 6 respectively, the output of single-chip microcomputer 6 is connected with the input of alarm 7, relay 2 respectively, and relay 2 outputs are connected with electrical source of power.
During work: when the wind speed that air velocity transducer 5 gathers in roadway 8, the wind speed information of being correlated with is transferred to single-chip microcomputer 6, and through single-chip microcomputer 6 analyzing and processing, if in roadway 8, wind speed is lower, single-chip microcomputer 6, by the control to relay 2, cuts off the energising of electrical source of power 1; When firedamp sensor 3 detects gas density in roadway 8, exceed standard, and in while roadway 8, wind speed is lower, and detection signal is sent to single-chip microcomputer 6, single-chip microcomputer 6 makes alarm 7 send too chimes of doom, and control relay 2 cuts off the energising of electrical source of power 1 simultaneously; In roadway 8, temperature is higher, and temperature pick up 4 is transferred to single-chip microcomputer 6 by the temperature information collected, through single-chip microcomputer 6 analyzing and processing, single-chip microcomputer 6 makes alarm 7 send too chimes of doom, prompting underground work personnel, now in roadway 8, temperature is higher, and being not suitable for need of work increases corresponding ventilation.
