Abstract
The utility model relates to a coal mine tunnel ventilation control system. The coal mine tunnel ventilation control system comprises a plurality of wind pressure sensors respectively arranged in each tunnel of a coal mine, a plurality of frequency converters respectively arranged in each tunnel of the coal mine and a single-chip microcomputer arranged in a coal mine signal control center. An output end of each wind pressure sensor is connected with an input end of one corresponding frequency converter through the single-chip microcomputer. An output end of each frequency converter is connected with an input end of a blower fan in the same tunnel. In work, by adopting the wind pressure sensors, the wind pressures of all tunnels are detected, and real-time wind pressure signals are input into the single-chip microcomputer for analysis. When the wind pressure in one tunnel deviates from a required reasonable wind pressure, the single-chip microcomputer outputs a control signal to the frequency converter corresponding to the tunnel, and according to the control signal, frequency conversion and speed regulation are carried out on the blower fan to ensure that the wind pressure in the tunnel reaches a reasonable value. According to the utility model, ventilation quantity is adjusted by changing the rotating speed of the blower fan, so that adjusting precision and stability are high, and the energy saving effect is substantial.
Description
Technical field
The utility model content belongs to mine equipment equipment control technology field, relates to a kind of coal mine roadway ventilated control system.
Background technology
Blower fan is the main ventilating machinary of protection safety of coal mines, and the main ventilation ability of mine laneway blower fan (comprising main air blower and standby fan) is generally to determine according to the flowing resistance in projected mine latter stage.At the operation initial stage, because ventilation is more sufficient, in order to meet air quantity and the wind speed of operation initial stage needs, way is in the past to turn down damper, or artificially increases flowing resistance and regulate tunnel blast.But not only waste electric energy by manual adjustment air quantity, and precision and reliability lower.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of air quantity degree of regulation and reliability is high, the significant coal mine roadway ventilated control system of energy-saving benefit.
The technical solution adopting is for achieving the above object such: the coal mine roadway ventilated control system providing is by being a plurality ofly divided into wind pressure sensor in each tunnel, colliery, forming with the same number of a plurality of frequency converter and the single-chip microcomputers that are arranged on colliery Signal control Center that are divided in each tunnel, colliery of wind pressure sensor, the output of each wind pressure sensor transfers to respectively the input of a corresponding frequency converter after single-chip microcomputer, and the output of each frequency converter is connected with an input that is arranged on the blower fan in same tunnel respectively.In practical application, utilize wind pressure sensor to detect the blast in tunnel, place, and analyze in the real-time wind pressure signal input single-chip microcomputer that all wind pressure sensors are detected, when the blast in certain tunnel departs from needed reasonable blast, by single-chip microcomputer, to frequency converter output control signal corresponding in this tunnel, this blower fan is carried out to frequency control, thereby guarantee that tunnel blast reaches reasonable value.
Compared with prior art, the utility model adopts the mode that changes rotation speed of fan to regulate ventilation, and not only degree of regulation and reliability are high, and energy-saving benefit is remarkable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a specific embodiment of the utility model.
The specific embodiment
Below with reference to accompanying drawing, the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, coal mine roadway ventilated control system described in the utility model is a kind of closed-loop control system, can control in real time rotation speed of fan and control fan delivery variation to reach, it is by a plurality of wind pressure sensors that are divided in each tunnel, colliery, form with the same number of a plurality of frequency converter and the single-chip microcomputers that are arranged on colliery Signal control Center that are divided in each tunnel, colliery of wind pressure sensor, the output of each wind pressure sensor transfers to respectively the input of a corresponding frequency converter after single-chip microcomputer, the output of each frequency converter is connected with an input that is arranged on the blower fan in same tunnel respectively.In concrete enforcement, in each tunnel in colliery, lay wind pressure sensor, by each wind pressure sensor in the wind pressure signal input signal control centre single-chip microcomputer in different tunnels, again by single-chip microcomputer by wind pressure signal input converter, thereby regulate the rotating speed of blower fan, reach the object of the air quantity of automatic adjusting blower fan.
