There is supervising device, supervising device is connected with reversible jet blower, sense cigarette positioner, magnetic valve and CO/VI detectors respectively.
Reversible jet blower is also referred to as bidirectional jet blower fan, can realize ventilation by controlling the traffic direction of blower fan
The control in direction;Due to vehicle, two way, piston effect caused by vehicle are not used to the ventilation in tunnel in tunnel, together
When the external world natural wind with jet blower operative orientation is opposite in tunnel when, the difficulty divulged information in tunnel, therefore profit will be increased
With the invertibity of bidirectional jet blower fan, the energy loss of blower fan can be reduced by adjusting the traffic direction of blower fan, artificial
The speed of ventilation smoke exhaust is controlled, maximumlly plays its fire fighting efficacy.Suspension bracket is provided with sense cigarette positioner, is mainly used in smog
Position caused by sensing and determination flue gas.Magnetic valve realizes automatically controlling for applicator.CO/VI detectors are a kind of tunnels
Tailored version CO and visibility detection means, on tunnel side wall, CO and visibility detection in tunnel are provided for supervising device
Value, the basic foundation set as ventilation.Supervising device respectively with reversible jet blower, sense cigarette positioner, magnetic valve and CO/
VI detectors connect, and realize unlatching and the traffic direction that blower fan is automatically controlled according to CO in tunnel and visibility data, automatically
The speed of ventilation is controlled, ensure that the operational efficiency of ventilating system.When the condition of a fire occurring in tunnel, sense cigarette positioner monitors
After smokescope reach threshold value, sense smoke signal and positional information are sent to supervising device, supervising device control magnetic valve and opened,
Start applicator, while closest tunnel face determined according to positional information, adjust the traffic direction of reversible jet blower,
Discharged fume to nearest tunnel face, while stronger ventilation intensity, the range of scatter of the smog so reduced to greatest extent, shorten cigarette
The discharge distance of mist, accelerates flue gas velocity, extends the escape time of indicator of trapped personnel, has ensured indicator of trapped personnel to greatest extent
Personal safety.
Further, the supervising device includes control module, wireless communication module and audible-visual annunciator, control module difference
It is connected with reversible jet blower, magnetic valve, CO/VI detectors, wireless communication module and audible-visual annunciator.Control module is as prison
The key data processing unit of device is controlled, is the most important function element of supervising device, it in time can pass through fire information
Wireless communication module is sent to the alarm receiver terminal of fire department, while controls audible-visual annunciator in time to the people around tunnel
Member's vehicle sends sound and light alarm signal.
Further, the sense cigarette positioner includes smoke detector and GPS module, smoke detector and GPS module point
It is not connected with control module.Smoke detector has the characteristics of high sensitivity, reliable and stable, can accurately experience smokescope
Increase, and send signal to control module in time;GPS module can accurately determine the position that the condition of a fire occurs and by information transmission
To control module
Further, the wireless communication module is 4G communication modules.
Further, the impeller diameter of the reversible jet blower be 1000mm, thrust >=1044N, air outlet velocity >=
34.2m/s, flow >=26.9m3/s.
Further, the arrangement spacing of the reversible jet blower is 100m.
Further, 15 times of the dead load of the bearing capacity of the suspension bracket >=reversible jet blower.Bearing suspension bracket can inverse morphism
The impulsive force that flow fan is brought when going on a long journey, ensure the stabilization and safety of ventilating system.
Prior art is contrasted, the utility model beneficial effect is:The utility model can pass through the CO concentration in tunnel
And state of visibility, direction of ventilation and air flux are adjusted in time.When running into the condition of a fire in tunnel, position on fire can be accurately determined
Put, while determine optimal smoke evacuation direction, start applicator, control the condition of a fire in time, extend the escape time of indicator of trapped personnel,
