The utility model content
The purpose of this utility model provides a kind of railway tunnel fire prevention ventilation system with the performance of ventilating of efficiently taking precautions against natural calamities.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of railway tunnel fire prevention ventilation system, comprise axial flow blower, field control cabinet, Long-distance Control cabinet, some collection recoil simulators, wherein axial flow blower, Long-distance Control cabinet, some collection recoil simulators all are connected with the field control cabinet, some collection recoil simulators are installed in the railway tunnel simultaneously, and axial flow blower is installed in the fire escape hole of railway tunnel.
As the further setting of such scheme, described axial flow blower links to each other by cable with the field control cabinet, and the Long-distance Control cabinet links to each other by cable line with the field control cabinet, and some collection recoil simulators link to each other by holding wire with the field control cabinet.
Described field control cabinet is installed in the fire escape hole of railway tunnel.
The utility model railway tunnel fire prevention ventilation system has three kinds of different control modes, comprises control mode, Long-distance Control mode and fire-fighting control mode on the spot.
1: control mode on the spot
Take precautions against natural calamities in the tunnel axial flow blower field control cashier's office in a shop, select control on the spot, with field control cabinet control opening-closing shaft flow fan.
2: the Long-distance Control mode
Receive the order that starts axial flow blower in the janitor's room, start axial flow blower (field control selection handle cashier's office in a shop needs at remote port) cashier's office in a shop in Long-distance Control, control signal is by the PLC of optical cable to the field control cabinet, by PLC start signal output axial flow blower, and resetting shaft flow fan run signal to Long-distance Control cashier's office in a shop.Stop axial flow blower, stop in the operation of Long-distance Control cabinet, control signal stops axial flow blower by the PLC of optical cable to the field control cabinet by the PLC output signal.
3: the fire-fighting control mode
(CO of collection site or the signal of CO2, concentration reach certain alarming value output signal when some collection recoil simulators have the fire-fighting signal; Or the fire-fighting signal that provides of tunnel system) when sending to control system, system starts axial flow blower automatically, and the overload protection of axial flow blower is excised.The maximum ventilation that assurance is taken precautions against natural calamities.When stopping axial flow blower, must or turn off the axial flow blower power supply to execute-in-place field control cabinet.
In a word, the utility model railway tunnel fire prevention ventilation system has the performance of ventilating of efficiently taking precautions against natural calamities, and can timely the fresh air outside the railway tunnel be sent in the railway tunnel under emergency conditions, to satisfy the demand that railway tunnel is taken precautions against natural calamities and ventilated, reach the purpose of smooth evacuation personnel under the emergency conditions.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is on-the-spot arrangement schematic diagram of the present utility model;
Fig. 2 is control system schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model railway tunnel fire prevention ventilation system, comprise axial flow blower 4, field control cabinet 3, Long-distance Control cabinet 6, some collection recoil simulators 1, wherein axial flow blower 4, Long-distance Control cabinet 6, some collection recoil simulators 1 all are connected with field control cabinet 3, some collection recoil simulators 1 are installed in the railway tunnel 2 simultaneously, and axial flow blower 4 is installed in the fire escape hole 5 of railway tunnel 2.
As optimal technical scheme, axial flow blower 4 links to each other by cable 9 with field control cabinet 3, and Long-distance Control cabinet 6 links to each other by cable line 8 with field control cabinet 3, and some collection recoil simulators 1 link to each other by holding wire 7 with field control cabinet 3.Field control cabinet 3 is installed in the fire escape hole 5 of railway tunnel 2.
In the utility model railway tunnel fire prevention ventilation system, axial flow blower 4, field control cabinet 3 etc. be exposed to on-the-spot equipment must be under 250 ℃ of conditions safe operation 1 hour.
Operating principle of the present utility model is as follows:
When mode is controlled on the spot, the control on the spot of field control cabinet 3, operation site switch board 3 starts axial flow blower 4.When stopping axial flow blower 4, operation site switch board 3 is controlled.
During remote mode control, field control cabinet 3 can carry out Long-distance Control, when starting axial flow blower 4, start axial flow blower 4 at Long-distance Control cabinet 6, control signal is passed through cable line 8 to the PLC of field control cabinet 3, by PLC start signal output axial flow blower 4, and resetting shaft flow fan 4 run signal are to Long-distance Control cabinet 6 screens.When stopping axial flow blower 4, operation Long-distance Control cabinet 6 stops axial flow blower 4, and control signal stops axial flow blower 4 by the PLC of cable line 8 to field control cabinet 3 by the PLC output signal.
When the fire-fighting mode was controlled, some collection recoil simulators 1 sent the fire-fighting signal to field control cabinet 3, and system starts axial flow blower 4 automatically, and the excision of the overload protection of axial flow blower 4, guarantees the maximum ventilation of taking precautions against natural calamities.When stopping axial flow blower 4, must or turn off axial flow blower 4 power supplys to execute-in-place field control cabinet 3.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
