Abstract
The utility model discloses automatic ventilation control systems under a kind of mine, including draft fan, automatic control unit and probe unit, the automatic control unit is set to draft fan side, and it is connected with the draft fan by cable, described draft fan one end is provided with air hose, the probe unit includes several sensor probes and signal processing unit, and the sensor probe is all set in the face of drive, and the signal processing unit is set to automatic control unit side.The start and stop that draft fan is controlled by the sensor of setting, that is, saved the energy, extends the service life of equipment, while improving the safety of shaft production；Sensor uses 18V low-voltage, creates security context to operating personnel；3 sensor probes of setting increase the reliability of equipment simultaneously；Signal processing unit is set at draft fan, and sensor probe is set to face, further improves the security reliability of probe unit.
Description
Technical field
The utility model belongs to underground ventilating technical field, and in particular to automatic ventilation control system under a kind of mine.
Background technique
Mine ventilation system is the general name of mine ventilation mode, method of ventilation and ventilation network.Currently, ventilation is in mine
After the completion of explosion, draft fan is switched on for a long time, however, as follows the shortcomings that this mode: 1, blower is switched on for a long time, increases
Production cost；2, the sensor of probe unit is easy to be damaged in face, leads to not keep the safety in production, reduces reliability.
Utility model content
The utility model solves the deficiencies in the prior art, and it is automatic to provide a kind of underground safe and reliable, that production cost is low
Ventilated control system.
The technical scheme adopted by the utility model is automatic ventilation control system under a kind of mine, including draft fan,
Automatic control unit and probe unit, the automatic control unit are set to draft fan side, and itself and the draft fan
It is connected by cable, described draft fan one end is provided with air hose, and the probe unit includes several sensor probes and letter
Number processing unit, several described sensor probes are connected with signal processing unit by signal cable, and the sensor is visited
Head is all set on the face of drive, and the signal processing unit is set to automatic control unit side.
Preferably, the probe unit is CO sensor, and its operating voltage is V.
Preferably, the quantity of the sensor probe is 3, and the sensor probe is set to area according to triangle
It holds in front.
Compared to the prior art, the utility model has the advantages that
1, extend service life of equipment and reduce production cost:
The start and stop that draft fan is controlled by the sensor of setting, that is, saved the energy, extends the service life of equipment, together
When improve the safety of shaft production.
2, safe and reliable:
Automatic control unit and sensor all use 18V low-voltage, create security context to operating personnel；It is arranged simultaneously
3 sensor probes increase the reliability of equipment；Signal processing unit is set at draft fan, and sensor probe
It is set to face, further improves the security reliability of probe unit.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
Automatic ventilation control system under a kind of mine, refering to fig. 1, including draft fan 1, automatic control unit 2 and detection
Unit 3, the automatic control unit 2 is set to 1 side of draft fan, and it is connected with the draft fan 1 by cable, institute
It states 1 one end of draft fan and is provided with air hose 4, the probe unit 3 includes several sensor probes 33 and signal processing unit
31, several described sensor probes 33 are connected with signal processing unit 31 by signal cable 32, and the sensor probe
33 are all set on the face of drive, and the signal processing unit 31 is set to 2 side of automatic control unit.Signal processing list
Member 31 and sensor probe 33 are provided separately, and are conducive to that signal processing unit 31 is protected not smashed by the slungshot of face.
In order to improve the safety of underground work, the probe unit 3 is CO sensor, and its operating voltage is 18V.
In order to improve the accuracy and reliability of the detection of sensor probe 33, the quantity of the sensor probe 33 is 3,
And the sensor probe 33 is set to face front end according to triangle.
Operation principles: after the completion of face excavation, a large amount of CO gas is contained in face air, sensor is visited at this time
The signal detected is forwarded to detector signal processing unit 31 by first 33, and signalling means processing unit 31 judges whether CO gas surpasses
Mark, if exceeded, signal processing unit can send signal to automatic control unit 2, and automatic control unit 2 passes through control relay
Device realizes the starting of draft fan 1, after probe unit 3 detects that CO gas concentration reaches criterion of acceptability, automatic control unit
2 can close draft fan 1.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
