The support frame has a folding structure which is contractively folded in an extending direction and comprises a front part, a middle part and a rear part which are connected through a hinge mechanism. The fire blanket is shape-fitted to the support frame and suspended from the inside thereof. The first operation part is arranged outside the support frame, and can separate the rear frame from the middle frame to fall to the ground during operation, and the second operation part is also arranged outside, and can separate the front frame from the middle frame to fall to the ground during operation. After the front frame and the rear frame are separated from the middle frame, the fire blanket forms an airtight space for isolating air in the supporting space of the supporting frame, so that quick fire extinguishing and fireproof isolation are realized. The fire isolating cover is convenient to store, move and deploy, integrally does not need a power supply, is safe and simple to operate, is suitable for lithium batteries and fuel automobile fires, adapts to common parking space specifications, and meets multi-scene emergency prevention and control requirements of parking lots, charging stations, maintenance workshops and the like.
