Auxiliary telescopic closure plate intussusception is embedded in the inside of primary seal closing plate, and closure plate one-level cylinder and tunnel angle are 45 °, is connected between tunnel and primary seal closing plate; Between closure plate secondary cylinder and auxiliary telescopic closure plate, angle is 30 °, is connected between primary seal closing plate and auxiliary telescopic closure plate.Top and the bottom, tunnel arrange closure plate gathering sill, facilitate closure plate telescopic moving betwixt.Underworkings is generally applied rail transport, and one group of guide rail device is set between closure plate and bottom gathering sill, is moved movable rail and realized the smooth closure of closure plate by cylinder.
Secondly, cross high-pressure hose and draw pressure-air as cylinder power, and air filter is set from down-hole high pressure air hose Netcom, anti-sealing, particulate matter enter cylinder.
The 3rd, lay monitoring system main transmission line road, power supply (127v) is installed, control substation (for example KJF16B substation), telemechanical switch, the time relay, two-position-five-way solenoid valve, the parts such as state sensor carry out Networking Debugging, guarantee the normal transmission of data.
Telemechanical switch is electrically connected with the time relay, and the time relay is electrically connected with two-position-five-way solenoid valve, and telemechanical switch control end is connected to control substation and outputs control mouthful for No. 1.Air filter is connected by high-pressure hose with two-position-five-way solenoid valve, and two-position-five-way solenoid valve is connected by high-pressure hose with actuating cylinder.State sensor is connected to controls No. 1 signal input of substation.By substation and the networking of ground monitoring system main control computer.
The automatically controlled anti-explosion two-position-five-way solenoid valve of two-position-five-way solenoid valve Q25-6-B type list, latus rectum 6mm, operating pressure 0.2-0.8Mpa, operating voltage DC24V, producer: the pneumatic complete factory of ease of Shanghai state.
Operation process:
The sealing in 1 tunnel
When mining face under mine generation floods, when fire or gas explosion need to be sealed this roadway workface, select the control substation at this device place, and the mouth of controlling for No. 1 of controlling this substation 9 is exported a high level, No. 1, this substation is controlled delivery outlet and is connect telemechanical switch 10 and move, normal battle becomes normally closed point, connect the one-level time relay 11, the secondary time relay 12, three grades of time relays 13 are powered, the one-level time relay 11 is closed after by time delay 1s, connect the 127v power supply of one-level two-position-five-way solenoid valve 14, electromagnetic valve 14 is opened, pressure-air in high pressure pipe network passes through high-pressure hose, two-position-five-way solenoid valve 14 promotes guide rail device cylinder 7 and stretches out, promoting moving track moves backward, for closure plate is abdicated space.
The secondary time relay 12 is closed after by time delay 10s, connect the 127v power supply of secondary two-position-five-way solenoid valve 15, electromagnetic valve 15 is opened, pressure-air in high pressure pipe network promotes closure plate one-level cylinder 3 by high-pressure hose, two-position-five-way solenoid valve 15 and stretches out, primary seal closing plate rotates Γ type gathering sill 5-1, the 5-2 to top vertically, the type of falling Γ gathering sill 5-3,5-42 that bottom is corresponding, and fit tightly with it.
Three grades of time relays 13 are closed after by time delay 20s, connect the 127v power supply of three grades of two-position-five-way solenoid valves 16, electromagnetic valve is opened, pressure-air in high pressure pipe network promotes closure plate secondary cylinder 4 by high-pressure hose, two-position-five-way solenoid valve 16 and stretches out, auxiliary telescopic closure plate is stretched out by the type of falling Π gathering sill 6-2 corresponding to Π type gathering sill 6-1, the bottom on top, contacts tightly with opposite auxiliary telescopic plate.State sensor 17, crosses control substation by the information exchange of locking device closure and transfers to ground main control computer, and main control computer is shown as sealing.
The unlatching in 2 tunnels
When fire in tunnel is determined and extinguished, while needing to open tunnel, control No. 1 control of this substation and output mouth, output low level, telemechanical switch motion, normally closed point becomes normal battle, relay power supply turn-off time, time relay action, two-position-five-way solenoid valve action, each cylinder shrinks in reverse order, and locking device is opened.
Succeeding in developing of this device, is quick sealing tunnel, down-hole disaster area after calamity, make personnel away from disaster area, the expansion of effectively controlling disaster area scope played good effect.It is high that this device has automaticity, safeguards the advantages such as simple, easy to install and use, reusable, has good Social benefit and economic benefit.
