Detailed description of the invention
The present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade.
As Figure 1-4, label 1-11 represents respectively: rain-proof type roof extract unit 1, ground parking room 2, carries car panoramic table 3, Induced fan 4, grid blinds electric vent 5, underground three-dimensional garage lifting passage 6, underground parking position 7, underground three-dimensional garage foot passage 8, ground parking room inwall 9, waiting area of parking terrace 10, carries car panoramic table booster fan 11.
Descend parking systems longitudinal section traditionally as shown in Figure 1, during by stopping/picking up the car, carry the keying of car panoramic table, realize the ventilation in underground stereo garage parking.When underground parking systems be in non-parking job state or underground parking garage need to carry out maintenance repair safeguard time, rely on tradition ventilation mode, air quality in underground garage cannot be guaranteed, and the safety of operation maintenance personnel and the normal operation of electric fixtures are on the hazard.
Carry 2.5 ~ 3.5 times considerations of boosting power according to rain-proof type roof extract unit blast of car panoramic table booster fan, the body length of booster fan is not more than 1.5m.
The air quantity of rain-proof type roof extract unit is considered according to being not less than underground stereo garage parking ventilation rate 6 times/h, and blast is considered according to being not less than 200Pa.
Induced fan on the parking position of underground is arranged on the top of car, installation site according to Induced fan air outlet to underground three-dimensional garage lifting channel center distance between centers of tracks at 6 ~ 8m scope control.
Separate unit Induced fan inlet scoop level is inclined upwardly, and air outlet is horizontally disposed with, and sprays to underground three-dimensional garage lifting channel center, to reach preferably smoke discharging effect.
The angle of inclination estimation equation of Induced fan inlet scoop is as follows:
Wherein
for level is inclined upwardly angle (o); Q
0induced fan air quantity (m
3/ h); Ps is Induced fan total head (Pa); T is air actual temperature (T); P is air actual pressure (kN/m
2); T
0for temperature (T) under standard air state; P
0for standard air state downforce (kN/m
2).The status of criterion is 273K, 1 standard atmospheric pressure.Air actual temperature in the present invention and air actual pressure value all can rule of thumb be chosen according to the meteorological data in the geographical position of reality or consult relevant form and obtain, and do not repeat them here.According to a preferred embodiment of the invention, separate unit Induced fan air output controls at 680 ~ 800m
3/ h, inlet scoop level is inclined upwardly 45o angle.
Novel underground parking systems longitudinal section, section are as in Figure 2-4.
When underground stereo garage parking is in non-parking/pick up the car job state, the pernicious gas utilizing Induced fan 4 air-vent to arrange and humiture probe, the Indoor Environmental Condition of Underground parking systems, when the humiture numerical value detected exceeds the safe range that electric fixtures normally runs, start the Induced fan of correspondence position, open the grid blinds electric vent 5, the booster fan 11 that carry on car panoramic table 3 simultaneously, carry out ventilation.When the humiture numerical value in the parking systems of underground still exceeds safe range, start the rain-proof type roof extract unit 1 in ground parking roof portion, carry out comprehensive induced draught.Underground stereo garage parking needs to carry out maintenance repair when safeguarding, the pernicious gas utilizing Induced fan 4 air-vent to arrange and humiture probe, the Indoor Environmental Condition of Underground parking systems, when the pernicious gas detected, humiture numerical value exceed the safe range of physical activity, start the Induced fan that underground parking garage is all, open the grid blinds electric vent 5 on the rain-proof type roof extract unit 1 in ground parking roof portion, year car panoramic table and booster fan 11 simultaneously, carry out comprehensive induced draught.
When underground stereo garage parking is in and stops/pick up the car job state, when adopting natural ventilation cannot meet the normal service requirement of underground parking garage electric fixtures, the Induced fan opening correspondence position carries out ventilation, open all Induced fans in top of underground stereo garage parking foot passage 8 simultaneously, open the grid blinds electric vent 5 carried on car panoramic table 3 simultaneously, carry out ventilation.
During the breaking out of fire of underground stereo garage parking, open all Induced fans in underground stereo garage parking, open the grid blinds electric vent 5, booster fan 11 and the rain-proof type roof extract unit 1 that carry on car panoramic table 3 simultaneously, thus ensure effectively to discharge fume in underground stereo garage parking, in the shortest time, high-temperature flue gas is got rid of.
