Parking firefighting facilities and automatic fire blanket elevating device thereof

Abstract

This invention relates to a parking fire prevention device and its automatic fire blanket lifting device. The parking fire prevention device is used on a vehicle body and includes a parking platform, an automatic fire blanket lifting device, and a flame-retardant gas supplier. The parking platform is for parking the vehicle body. The automatic fire blanket lifting device is installed on the parking platform and includes a fire blanket and an automatic lifting mechanism connected to the fire blanket and used for storing or unfolding the fire blanket. When the fire blanket is unfolded by the automatic lifting mechanism, it is pulled by the automatic lifting mechanism to cover the parking platform while maintaining a distance from the vehicle body, until the fire blanket and the parking platform form a closed cavity surrounding the outside of the vehicle body, and a gap space is formed between the fire blanket and the vehicle body. The flame-retardant gas supplier is provided corresponding to the closed cavity and fills the gap space with flame-retardant gas.
