The invention relates to the related field of
tunnel safety devices, in particular to tunnel fire guiding and wet towel providing equipment. The tunnel fire guiding and wet towel providing equipment comprises a
machine body, an indicating cavity with a leftward opening is formed in the
left wall of the
machine body,
torsion spring cavities are formed in the bottom wall of the indicating cavity ina front-back symmetrical and communicating mode, torsion springs are fixedly arranged on the bottom walls of the
torsion spring cavities, and indicating shafts are fixedly arranged at the ends, away from the bottom walls of the
torsion spring cavities, of the torsion springs. After
smoke concentration is recognized through a
smoke alarm, a channel is controlled to be opened, an empty cup is drivento rotate in the
smoke pumping and sucking process of an
air pump, and then an indicating plate is triggered to rotate; and meanwhile, the empty cup can still rotate when the indicating plate cannotrotate through rotation of different
ratchet wheels, an indicator board is made to point to the upper air opening when dense smoke occurs in a fire, meanwhile, power is transmitted from the empty cupthrough manual engagement and disengagement, and thus a wet towel is provided.
