Handling Facility and Ventilation Device

Abstract

An arranging facility, a parking facility, a handling facility, and a ventilation device. A vehicle maintenance facility as the arranging facility comprises a vehicle maintenance booth as an arranging space and a forcible air supply/discharge mechanism. The vehicle maintenance booth is surrounded by side walls and a ceiling wall as partition walls on its periphery. A maintenance vehicle on which a fuel battery as an energy converter is mounted is temporarily disposed in the vehicle maintenance booth. Also, the air supply/discharge mechanism comprises an air intake device feeding air to the vehicle maintenance booth and an air discharge device discharging the air from the vehicle maintenance booth to dilute hydrogen gas leaking from a vehicle under maintenance.

1 . A handling facility, comprising:
 a work booth whose periphery is surrounded by partition walls and in which a fuel-cell electric vehicle having a fuel cell mounted thereon is termporarily, arrangeably disposed, the fuel cell using an inflammable gas as a fuel, and in which handling work for the fuel-cell electric vehicle is performed, and   a forcible gas supply/discharge mechanism that dilutes the inflammable gas leaking out of the the fuel cell into the work booth by supplying a diluent gas to the work booth and discharging gas from the work booth.   
   
   
       2 . The handling facility according to  claim 1 , wherein
 the inflammable gas is a gas lighter than the diluent gas and   the gas supply/discharge mechanism supplies the diluent gas from below the work booth and the gas is discharged from above the work booth.   
   
   
       3 . The handling facility according to  claim 1 , further comprising:
 an inflammable gas sensor detecting the inflammable gas having leaked into the work booth; and   a control device controlling a supply or discharge of the gas supply/discharge mechanism in accordance with a detection result of the inflammable gas sensor.   
   
   
       4 . The handling facility according to  claim 3 , wherein
 if an inflammable gas satisfying a predetermined condition is detected, the control device activates the gas supply/discharge mechanism.   
   
   
       5 . The handling facility according to  claim 4 , wherein
 an inclined-face structure accumulating the inflammable gas that rises or falls due to a density difference from the gas filling the work booth under normal conditions is provided in an upper part or lower part of the work booth and   the inflammable gas sensor detects the accumulated inflammable gas.   
   
   
       6 . The handling facility according to  claim 3 , wherein
 if an inflammable gas satisfying a predetermined condition is detected, the control device increases supply and discharge amounts by the gas supply/discharge mechanism.   
   
   
       7 . The handling facility according to  claim 3 , wherein
 the gas supply/discharge mechanism includes a plurality of supply ports provided at mutually different positions or a plurality of exhaust ports provided at mutually different positions, and   if an inflammable gas satisfying a predetermined condition is detected, among the plurality of supply ports or exhaust ports, the control device changes a combination of supply ports or exhaust ports to be activated.   
   
   
       8 . The handling facility according to  claim 3 , wherein
 the gas supply/discharge mechanism comprises a circuit for re-supplying at least a portion of the gas discharged from the work booth back to the work booth and   if an inflammable gas satisfying a predetermined condition is detected, the control device suppresses or stops a gas circulation.   
   
   
       9 . The handling facility according to  claim 1 , wherein
 a vehicle on which an energy converter is mounted is inspected and maintained in the work booth.   
   
   
       10 - 11 . (canceled) 
   
   
       12 . A device providing ventilation to work booth whose periphery is surrounded by partition walls and in which a fuel-cell electric vehicle having a fuel cell mounted thereon is temporarily, arrangeably disposed, the fuel cell using an inflammable gas as a fuel, and in which handling work for the fuel-cell electric vehicle is performed, comprising:
 a forcible gas supply/discharge mechanism that dilutes the inflammable gas leaking out of the fuel cell into the work booth by supplying a diluent gas to the work booth and discharging gas from the work booth.
