Tunnel fire guiding and wet towel providing equipment

Abstract

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.

Description

technical field [0001] The invention relates to the relevant field of tunnel safety devices, in particular to tunnel fire guidance and wet towel supply equipment. Background technique [0002] Tunnels are buildings buried underground. They are a way of utilizing underground space. They can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. During construction and use, safety issues are still the top priority. Tunnel collapses, explosions, and fires have always occurred from time to time. Among them, tunnel fires often produce thick smoke. The biggest problem faced by personnel when escaping is thick smoke. They should run to the windward, and the visibility in the thick smoke is low, so they can only rely on the escape lights. , but the indicator light at this stage does not indicate where the upwind vent is located, and few people always have things such as water and towels to cover their mouths and noses, so it is nec...

[0002] Tunnels are buildings buried underground. They are a way of utilizing underground space. They can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. During construction and use, safety issues are still the top priority. Tunnel collapses, explosions, and fires have always occurred from time to time. Among them, tunnel fires often produce thick smoke. The biggest problem faced by personnel when escaping is thick smoke. They should run to the windward, and the visibility in the thick smoke is low, so they can only rely on the escape lights. , but the indicator light at this stage does not indicate where the upwind vent is located, and few people always have things such as water and towels to cover their mouths and noses, so it is necessary to set up a tunnel fire guide and wet towels to provide equipment to improve the above question
