Description
Technical field
The present invention relates to mire ventilation safety field, more particularly to a kind of main fan Explosion-proof cap vapour-pressure type automatic open close
Control device.
Background technology
Coal is still the main energy sources in China at present.The complex geologic conditions of coal in China preservation, mineral reserve layout is uneven,
Coal Industrial structure diversification, these all to China coal mining industry with foreign countries compared with bring bigger difficulty, also between
Connect the general layout for causing China's accident of mine disaster to take place frequently.Explosion-proof cap is one of most important safety component of mine ventilation system, is being protected
It is particularly important in barrier safety in production.
Explosion-proof cap effect has：(1) mine ventilation system is prevented during normal ventilation to completely cut off underground air-flow and surface air
When explosion accident occurs for Air escape branch (2) underground, prevent HTHP shock wave or tight roof large area is caved in caused punching
Hit ripple and storm damage main fan in mine；It can be resetted after blast, good ventilation environment is provided for emergency management and rescue after calamity,
(3) mine blackout, main fan because maintenance or failure it is out of service when can open Explosion-proof cap using natural ventilation pressure ventilation.
(4) when underground intake occurs fire or toxic gas be present, in order to prevent flame and toxic gas from being endangered into exploiting field
Miner's life, it is necessary to carry out inverted ventilation fire extinguishing in time, now need in time to compress Explosion-proof cap, prevent from leaking out.(5) for small part
Coal mine ground uses single air channel VENTILATING SYSTEM BY VOLTAGE STEP, because blower performance test of no standby air channel for every 3 years 1 time uses,
Mine needs to stop production, and opens Explosion-proof cap as the interim air inlet of performance test, is reclosed after end to be tested.
In order to ensure that colliery continues safe and efficient production, although being made that both at home and abroad to main fan Explosion-proof cap
Substantial amounts of research work, constantly improves the safe coal production status in China, but still suffers from Explosion-proof cap and leak out, and resets too late
When, reset routine complex operation, it is impossible to be applied to the medium many problems of emergency management and rescue, the presence pair of these problems in catastrophe period
Great threat is constituted in the safety of mine.Main fan Explosion-proof cap is primarily present problems with this stage：
(1) Explosion-proof cap is blown off well head or gross distortion by impact air-flow after gas explosion occurs.
(2) sealing fluid of Explosion-proof cap can produce the phenomenon of immersion due to Explosion-proof cap and foundation means, by oil seal
It is changed into water-stop, easily freezes in the winter time, loses the effect of sealing.
(3)) Explosion-proof cap opens and closes many steps in program and needs to be accomplished manually, and keying speed is slow, and keying effect is bad, is sending out
After raw explosion accident, delay the time of emergency management and rescue during catastrophe.
(4) mine blackout, main fan because maintenance or failure it is out of service need using natural ventilation pressure ventilation when,
Explosion-proof cap rapidly can not be opened and closed.
(5) there is certain obstacle in achievements conversion, and theoretical research can not meet site application conditions, it is impossible to occur in mine
During catastrophe, inverted ventilation and emergency management and rescue, quickly opening and closing, and ensure that Explosion-proof cap may be reused and do not damaged easily
It is bad.

The operation principle of baric systerm is：Pneumatic Transmission is moved using compressed gas as working media by the pressure transmission of gas
The Fluid-transmission of power or information.The system of passing power is that compressed gas is conveyed into pneumatic cylinder via pipeline and control valve,
The pressure energy of compressed gas is converted to the mechanical energy of piston rod 5 and work done；The system of transmission information is to utilize pneumatic logic element
Or fluidic is to realize the functions such as logical operation, i.e. gas control.Gas control is so that electric signal control is converted into pressure control signal
Formed for master mode, using electromagnetism and electrically controlled valve as main element.Primary circuit has：(1) two group of flow distributing and collecting formula of pneumatic cylinder 4 is double
To synchronization loop；(2) ventilation blower ventilation in different operating modes pneumatic cylinder enter 25, gas outlet 24 open and close, conversion and control return
Road；(3) commutation of pneumatic cylinder piston rod 5 moving loop；(4) piston rod 5 is flexible in place, inverted ventilation when piston rod 5 stretch out locking and solution
Except locking control loop.After pneumatically being opened to folding Explosion-proof cap 7, flexible by piston rod 5 can be controlled pneumatically to folding
The opening degree of Explosion-proof cap.
The course of work：During normal ventilation, pneumatic cylinder 4 treats standby operating mode to be motionless for a long time, and baric systerm is to pneumatically to folding
Explosion-proof cap 7 does not produce any push-and-pull and locking active force.
When explosion accident occurs for underground, pneumatically folding Explosion-proof cap 7 is washed open by shock wave, is arranged on column and herringbone beam
The Explosion-proof cap at place opens and closes position sensor and sent pneumatically to the open signal of folding Explosion-proof cap 7；After shock wave disappears, grasped in computer room
Make closing control button, programmed instruction ECU and pneumatic control circuit control pressure cylinder 4 through programmable controller setting, piston
Bar 5 stretches out will pneumatically cover well head to the Rapid reset of folding Explosion-proof cap 7, ensure the fast quick-recovery ventilation of mine, should for catastrophe period
First aid, which is helped, creates good ventilation environment, so as to prevent destruction of the underground subsequent explosion to chief ventilators.
When needing gravity-flow ventilation, operation open control button, programmable controller setting programmed instruction ECU with
The bi-directional synchronization loop of pneumatic cylinder 4, two pneumatic cylinder synchronization telescope motions, coordinates pneumatic cylinder piston 21 to act, and it is pneumatic right to realize
The unlatching of folding Explosion-proof cap 7；
When recovering normal ventilation, operate X button, by the programmed instruction ECU that programmable controller is set with
The bi-directional synchronization loop of pneumatic cylinder 4, air compressor 25, the conversing circuits of gas outlet 24, cooperation pneumatic cylinder piston 21 act, real
The now pneumatically closing to folding Explosion-proof cap 7.
During back lass, operation locking and unblock button, the programmed instruction ECU set by programmable controller
Interlocked with gas control locking with relief circuit and hydraulic cylinder piston rod force sensor, realize the locking and unblock of Explosion-proof cap.
When fire occurs for underground intake or when toxic and harmful gas be present, operation locking and unblock button, by can
Programmable controller：Abbreviation PLC, it is the part of Electrified Transmission program control system, is a kind of electronics of digital operation
System, by the input and output interface of numeral or simulation, control various types of plant equipment or production process.Input interface
Effect is the input channel with the connection interface of field control, and output interface effect is to scene by live output interface circuit
Execution unit export corresponding control signal.The electronic signal that feedback is come from scene, as Explosion-proof cap opens and closes position sensor, gas
Cylinder pressure converter, piston rod force sensor etc., PLC is entered by input interface, then letter will accordingly be controlled by output interface
Number send programmed instruction ECU and the gas control locking and relief circuit and hydraulic cylinder piston rod dynamics of pneumatic control system setting to
Sensor is combined, and realizes the locking and unblock of Explosion-proof cap, so as to prevent flame and toxic gas from endangering miner's life into exploiting field
Life.
Above example both can carry out near-earth operation in pump house, also can carry out remote control in computer room.Can be according to reality
