Description
Technical field
Ventilation blower handoff technique is the utility model is related to, specifically a kind of mine fan automatic switching control equipment.
Background technology
In coal mine operation, underground is usually mounted with main fan and back-up ventilation machine.If main fan is being transported
Broken down in row, then must be aerated machine-cut and change（Start back-up ventilation machine）, to ensure underground ventilating.In prior art
Under the conditions of, ventilation blower switching mainly uses what is manually carried out.But practice have shown that, manually it is aerated machine-cut and changes in the presence of switching
The problem of time is long, underground ventilating interruption and gas exceeding limit are thus easily caused, so as to easily trigger work safety accident.For this
It is necessary to invent a kind of brand-new ventilation blower switching device, is easily caused with solving existing ventilation blower handoff technique in underground ventilating
The problem of disconnected and gas exceeding limit.
The content of the invention
The utility model easily causes underground ventilating interruption and gas exceeding limit to solve existing ventilation blower handoff technique
A kind of problem, there is provided mine fan automatic switching control equipment.
The utility model adopts the following technical scheme that realization：
Mine fan automatic switching control equipment, including main fan, back-up ventilation machine, contactor, relay, indicator lamp,
Loudspeaker, battery, controlling switch, air quantity switch of air tube sensor, live wire, zero line；
Wherein, the movable contact of two groups of main contacts of contactor is connected with live wire and zero line respectively；Two groups of masters of contactor touch
The normally closed stationary contact of point is connected with the fire line terminal and zero terminal of main fan respectively；Two groups of main contacts of contactor it is normally opened
Stationary contact is connected with the fire line terminal and zero terminal of back-up ventilation machine respectively；Coil one end of contactor is connected with live wire, separately
One end is connected by the normally opened contact of relay with zero line；
Air quantity switch of air tube sensor is installed in the air outlet of main fan；The normally closed of air quantity switch of air tube sensor is touched
Point one end passes sequentially through the positive pole connection of controlling switch, the coil of relay and battery, and the other end passes sequentially through indicator lamp, raised
The negative pole of sound device and battery connects.
Specific work process is as follows：Step 1：The start button of main fan and the startup of back-up ventilation machine are pressed respectively
Button, now main fan start working, back-up ventilation machine do not work, and air quantity switch of air tube sensor detects main fan in real time
Air output.If the air output of main fan is more than or equal to the setting value of air quantity switch of air tube sensor, air quantity switch of air tube
The normally-closed contact of sensor disconnects.If the air output of main fan is less than the setting value of air quantity switch of air tube sensor, air duct
The normally-closed contact closure of duct air flow switch sensor.Step 2：Close controlling switch.After controlling switch is closed, if indicator lamp is not
Bright and loudspeaker not sounding, then show that the normally-closed contact of air quantity switch of air tube sensor disconnects, be indicated above going out for main fan
Air quantity is more than or equal to the setting value of air quantity switch of air tube sensor, so as to showing main fan normal operation, now relay
Coil losing electricity, the normally opened contact of relay disconnect, the coil losing electricity of contactor, the normally closed stationary contact of two groups of main contacts of contactor
Closure, the normally opened stationary contact of two groups of main contacts of contactor disconnect, and main fan works on, and back-up ventilation machine does not work.
After closing controlling switch, if indicator lamp is lighted and loudspeaker sounding, show that the normally-closed contact of air quantity switch of air tube sensor closes
Close, the air output for being indicated above main fan is less than the setting value of air quantity switch of air tube sensor, so as to show that main fan goes out
Existing failure, now the coil of relay obtain electric, the normally opened contact closure of relay, the coil of contactor obtain it is electric, the two of contactor
The normally closed stationary contact of group main contacts disconnects, and the normally opened stationary contact closure of two groups of main contacts of contactor, main fan is stopped,
Back-up ventilation machine is started working.Step 3：After the start-up operation of back-up ventilation machine, main fan is overhauled.Maintenance is completed
Afterwards, the coil losing electricity of controlling switch, now relay is disconnected, the normally opened contact of relay disconnects, the coil losing electricity of contactor, connect
The normally closed stationary contact closure of two groups of main contacts of tentaculum, the normally opened stationary contact of two groups of main contacts of contactor disconnect, main fan
Restart work, back-up ventilation machine is stopped.Step 4：After back-up ventilation machine is stopped, re-closes control and open
Close, be thereby returned to step 2.
Based on said process, compared with existing ventilation blower handoff technique, mine fan described in the utility model is automatic
Switching device is realized and is automatically and quickly aerated machine-cut when main fan breaks down and changes by using brand new,
Thus switching time is greatly shortened, so as to effectively prevent underground ventilating interruption and gas exceeding limit, and then effectively prevent life
Produce security incident.
The utility model is rational in infrastructure, ingenious in design, efficiently solves existing ventilation blower handoff technique and easily causes underground
The problem of ventilation interruption and gas exceeding limit, suitable for coal mine operation.
