Description
Technical field:
This utility model relates to a kind of goaf on-line measuring device, belongs to mining equipment technical field.
Background technology:
Mine fire is one of colliery major casualty, and spontaneous combustion in goaf accounts for the most at high proportion.Mine fire once occurs,
Light then affect safety in production, heavy then burn coal resources and material equipment, even cause gas, coal-dust explosion.Therefore, carry out and adopt
In dead zone, the prediction of spontaneous combustion early warning of coal and location are significant for reducing life and property loss, the key of prevention
It is every harmful gas concentration in goaf is carried out periodic detection.The current each mining area collection master to goaf harmful gas
Tube Bundle Monitoring System to be used, utilizes the infrared technique analysis to mine gas composition, it is achieved CO, CO2, CH4, O2, N2 (calculate
Value) etc. 24 hours on-line continuous monitoring of gas content, its changes of contents situation is predicted.Tube Bundle Monitoring System mostly is big
Type mine detection design, a complete set of equipment is complicated, and management technique requires higher, and equipment cost is costly.And system is to coal seam certainly
The various gas marker analysis precisions of combustion hidden danger are relatively low, and the sensor element life-span is short, need to often change, it is impossible to follow the tracks of inspection
Survey forecast etc..Beam tube easily damages appearance breakage gas leakage and makes measurement result inaccurate；Meanwhile, beam tube system construction difficulty is big,
Inconvenience is safeguarded.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in construction, easy to maintenance, can carry out data record and energy and ore deposit
Well is networked, the goaf on-line measuring device that difficulty of construction is little.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of goaf on-line measuring device, surveys instrument box, communication including admission line, negative pressure pump, outlet pipe, health check-up
Network, ground monitoring computer.Admission line, one end of outlet pipe are connected with goaf chamber, admission line, outlet pipe
The other end and health check-up survey instrument box and be connected, negative pressure pump is arranged in admission line, and health check-up is surveyed instrument box and passed through communication network
It is connected with ground monitoring computer.Periodically the gas in the chamber of goaf is pumped into gas control instrument case by negative pressure pump to enter
Row detection, gas control instrument case carries out display and the remote transmission of data.
The beneficial effects of the utility model are, simple in construction, and difficulty of construction is little, easy to maintenance, and degree of accuracy is high, can count
According to record and remote transmission.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1 admission line, 2 negative pressure pumps, 3 outlet pipes, 4 gas control instrument casees, 5 communication networks, 6 ground monitorings
Computer.
Detailed description of the invention:
As it is shown in figure 1, a kind of goaf on-line measuring device, including admission line (1), negative pressure pump (2), outlet pipe
(3), instrument box (4), communication network (5), ground monitoring computer (6) are surveyed in health check-up.Admission line (1), the one of outlet pipe (3)
End is connected with goaf chamber, and admission line (1), the other end of outlet pipe (3) are connected with gas control instrument case (4),
Negative pressure pump (2) is arranged in admission line (1), and gas control instrument case (4) is by communication network (5) and ground monitoring computer
(6) it is connected.Periodically goaf gas is pumped into gas control instrument case (4) by negative pressure pump (2) to detect, gas detecting
Instrument box (4) carries out display and the remote transmission of data.
Operation principle: on-line measuring device is arranged near the chamber of goaf, admission line (1), the one of outlet pipe (3)
End is connected with goaf chamber, and admission line (1), the other end of outlet pipe (3) are surveyed instrument box (4) with health check-up and be connected, negative
Press pump (2) is arranged in admission line (1), the gas in the chamber of goaf under the effect of negative pressure pump (2) through admission line (1)
Inflow gas instrumentation case (4), returns through outlet pipe (3) after the various instrument in gas control instrument case (4) detects again
Flow in the chamber of goaf.Data after detection can pass through charactron field observation.Gas control instrument case (4) is built-in simultaneously
The ground monitoring computer (6) that the data of detection are sent to control room by communication network (5) by remote communication module is remembered
Record and display, it is also possible to carry out data transmission with neighbouring automatic monitored control system.
