Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust and ventilation equipment, and more specifically, to a mobile fire-fighting smoke exhaust and purification vehicle-mounted device. Background Art

[0002] With the continuous growth of the number of motor vehicles, in order to ease the urban traffic pressure, the number of highway tunnels and urban underpasses is increasing day by day. At the same time, fire accidents in tunnels also occur frequently. Looking at the common characteristics of such accidents, cars spontaneously combust in tunnels, the fire time is short, and after the fire, it will reach a very high temperature in a very short time; the temperature generated by such fire accidents will cause serious damage to the fire smoke exhaust equipment and supporting accessories configured in the tunnel (the current effective working temperature of the jet fan in the tunnel is within 300°C), resulting in the jet fan in the tunnel being unable to perform smoke exhaust work normally when such fire accidents occur, and these fans cannot be moved and cannot effectively perform tunnel smoke exhaust operations, so there is an urgent need to improve this.
