Abstract
A disaster prevention system for underground spaces has a compressed air supply system and an independent power generator installed in an underground space. In the event of a disaster, the compressed air supply system discharges compressed air into an underground space in order to maintain the air pressure therein at a higher level than that of the external atmosphere. The independent power generator generates electrical energy which provides the necessary lighting for the underground space.
Claims4
A disaster prevention system for an underground space comprising liquid air storage means for storing liquid air in said underground space, a power generator means in said underground space, conduit means in said underground space leading from said liquid air storage means to a plurality of locations in said underground space such that liquid air released from said liquid air storage means provides compressed air in said conduit means, said conduit means having a plurality of compressed air outlets located at a plurality of locations in said underground space such that the compressed air in said conduit means is discharged through said outlets to thereby maintain said underground space at pressure higher than atmospheric pressure, said conduit means comprising a conduit means portion leading to said generator means such that the air for operating said generator means is supplied by said liquid air storage means via said conduit means.
