Technical field
The utility model belongs to the compressor room ventilation technical field of structures of natural gas mother station, particularly a kind of CNG compressor room and to meet an urgent need exhaust system.
Background technology
The compressor room of compressed natural gas CNG (CompressedNaturalGas) mother station is the most key link of mother station, it is the most crucial position ensureing that whole CNG mother station normally works, current CNG compressor room all adopts hand door and window, by staff's manual unlocking door and window after combustible gas detector sends warning, the fuel gas of CNG compressor room content overproof is discharged, this mode just must arrange fixed personnel's moment to pay close attention to the warning device of CNG compressor room, once operator on duty leaves the post to do other work, bring very huge threat will to whole CNG compressor room.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of CNG compressor room and to meet an urgent need exhaust system.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of CNG compressor room is met an urgent need exhaust system, comprise CNG compressor room, the roof of CNG compressor room has multiple structure identical square hole side by side, by hinge strand dress skylight on each square hole, rope is fixedly mounted with at the opening end in skylight, the other end of rope is connected with the top of strut leading screw straight down, the roof inwall of each sunroof hole side is all fixedly mounted with explosion-proof drive motors, threaded motor shaft extends to the below of strut leading screw, motor shaft top is installed in shaft coupling, shaft coupling is packed on the inwall on roof by band iron, strut leading screw is moved up and down by motor shaft drive through shaft coupling, two combustible gas detectors are fixed with near two of roof relative corner places at CNG compressor room, be connected with the Switching Power Supply be fixedly mounted with by wire after the signal output part parallel connection of two combustible gas detectors, by the supplying power for outside of the output signal trigger switch power supply of combustible gas detector, one tunnel of Switching Power Supply exports and is connected with explosion-proof drive motors, another road of Switching Power Supply exports and is connected with the alarm be arranged on roof.
And the area sum of the square hole that described multiple structure is identical is more than or equal to 1/5 of roof gross area volume.
And, after Switching Power Supply receives the signal output of combustible gas detector, Switching Power Supply provides rotating forward operating voltage for explosion-proof drive motors, explosion-proof drive motors drives and opens skylight, after Switching Power Supply stops receiving the output signal of combustible gas detector, Switching Power Supply provides reversion operating voltage for explosion-proof drive motors, and explosion-proof drive motors drives closes skylight.
And, after the signal receiving combustible gas detector for 10 minutes when Switching Power Supply is continuous exports, Switching Power Supply provides working power, by alarm equipment alarm for alarm, after Switching Power Supply stops the signal receiving combustible gas detector to export, Switching Power Supply stops powering for alarm.
And when alarm continuous alarm is after 5 minutes, Switching Power Supply is that the power that alarm exports doubles, and implements urgent warning.
And described square hole is of a size of 1m × 1m.
Advantage of the present utility model and good effect are:
1, the utility model will arrange dual-alarm mechanism in CNG compressor room, and alarm sound changes in time and changes, and make warning more targeted, further increase the safety of CNG compressor room.
2, ventilation louver is opened at CNG compressor room top by the utility model, is more applicable to the lighter-than-air feature of natural gas, is conducive to the discharge of natural gas in CNG compressor room.
3, air hole of the present utility model is controlled by warning device, achieves automatic air-exchanging, decreases full-time worker on duty, improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model system.
Detailed description of the invention
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of CNG compressor room is met an urgent need exhaust system, as shown in Figure 1, comprise CNG compressor room 1, the roof of CNG compressor room has multiple structure identical square hole 3 side by side, each square hole twists dress skylight 4 by hinge 2, rope is fixedly mounted with at the opening end in skylight, the other end of rope is connected with the top of strut leading screw 5 straight down, the roof inwall of each sunroof hole side is fixedly mounted with explosion-proof drive motors 10, threaded motor shaft 9 extends to the below of strut leading screw, the top of motor shaft is installed in shaft coupling 6, shaft coupling is packed on the inwall on roof by band iron, strut leading screw is moved up and down by motor shaft drive through shaft coupling, when strut leading screw is up, incipient stage strut leading screw backs down skylight, after certain angle is opened in skylight, strut leading screw is separated from the outer in skylight, continued to drive skylight to open greater angle by rope, equally, drive skylight to close when strut leading screw is descending, two combustible gas detectors 8 are fixed with near two of roof relative corner places at CNG compressor room, be connected with the Switching Power Supply 11 be fixedly mounted with by wire after the signal output part parallel connection of two combustible gas detectors, by the supplying power for outside of the output signal trigger switch power supply of combustible gas detector, one tunnel of Switching Power Supply exports and is connected with explosion-proof drive motors, another road of Switching Power Supply exports and is connected with the alarm 7 be arranged on roof.
In concrete enforcement of the present utility model, the area sum of the square hole that described multiple structure is identical is more than or equal to 1/5 of roof gross area volume.
