Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model pvc pipe overhang cross-sectional view.
Specific embodiment
As shown in Figs. 1-2, a kind of mine ventilation wind speed, wind pressure monitoring system, including blower 5, brattice 6, air velocity transducer 2
With PLC control system 1, the PLC control system 1 is mounted on 6 upper end of brattice, and the blower 5 is installed through on brattice 6, institute
It states air velocity transducer 2 and is mounted on the tunnel centre-height apart from 5-8 meters of 5 air inlet of blower；The air velocity transducer 2 and blower 5
Tunnel centre-height between air inlet is fixed with the first wind pressure sensor 3, the 5 air outlet tunnel the 8-10 meter Chu center of blower
Height is fixed with the second wind pressure sensor 4；The blower 5, air velocity transducer 2, the first wind pressure sensor 3, the second wind pressure sensing
Device 4 is electrically connected with PLC control system 1 respectively.
It is understood that PLC control system 1 is connect with mine master control system electric wire, by master control system power supply or lane
Power supply power supply in road, blower 5 is by the power supply power supply in tunnel.Air velocity transducer 2, the first wind pressure sensor 3, the second wind pressure pass
Sensor 4 is mounted on the centre-height in tunnel, to measure accurate data.PLC control system 1 controls blower 5, wind simultaneously
Fast sensor 2, the first wind pressure sensor 3, the second wind pressure sensor 4, when work, PLC control system 1 is real-time by each sensor
Data are compared with preset data, judge the working condition of blower 5, timely to adjust the working condition of blower.Separately
Outside, air velocity transducer 2, the first wind pressure sensor 3, the second wind pressure sensor 4 are powered by PLC control system 1, can simplify conducting wire
Arrangement, facilitate the installation and maintenance of system.
Further, the air velocity transducer 2, the first wind pressure sensor 3, the second wind pressure sensor 4 are all made of pvc pipe 8
It is fixed on the wall, and vertical with airflow direction.Specifically, pvc pipe 8 is fixed on wall, it, will by the way that branch is arranged
Air velocity transducer 2, the first wind pressure sensor 3, the second wind pressure sensor 4 are separately fixed at the end of branch, and its conducting wire is worn
Pvc pipe is crossed to connect with PLC control system 1.Pvc pipe 8 not only can guarantee that sensor was not influenced to generate displacement by air-flow, but also can protect
Protect and fix its conducting wire, make to install, safeguard it is more convenient.In addition sensor vertical is installed in air-flow, can accurately be more measured
Corresponding parameter.
Further, 1 lower end of PLC control system is equipped with alarm 7 and is electrically connected.That is, whole
Alarm 7 is also equipped in a system, and alarm 7 and PLC control system are electrically connected.When PLC control system 1 passes through sensor
The data of acquisition when working condition by repeatedly reconciling blower, cannot still reach preset requirement compared with preset data
When, alarm signal is issued by alarm 7 immediately, staff is notified to handle.Alarm is mounted on blower brattice, can be allowed
Staff quickly finds corresponding failure blower, shortens troubleshooting time, prevents the generation of ventilation accident.
Further, the 8 overhang cross section of pvc pipe is streamlined.It should be understood that the streamline of pvc pipe 8
Type surface is parallel with gas circulating direction.Setting can reduce pvc pipe 8 to the disturbing influence of gas in tunnel, to reduce in this way
The measurement error of sensor；Can reduce pressure suffered by pvc pipe 8 simultaneously, sensor is subjected to displacement when preventing wind pressure excessive,
Guarantee the accuracy of measurement.
