Portal fire blanket structure

Abstract

This invention relates to a door-type fire blanket structure, which mainly includes a storage box with an internal pivot for rolling up the fire blanket. Movable door frames are provided on both sides of the storage box. Thus, the fire blanket can be manually pulled down to position itself and moved towards the target vehicle through the movable door frames, allowing the fire blanket to be smoothly laid on the target vehicle. It can achieve the effect of fire extinguishing without power supply.

Claims

1. A door-type fire blanket structure, comprising: a storage box having an internal space and a blanket outlet connected thereto; a pivot mounted on the internal space of the storage box, with the fire blanket wound around it, the fire blanket passing through the blanket outlet, and a thrust mechanism provided on the pivot to ensure smooth release of the fire blanket; and two movable door frames respectively installed on both sides of the storage box, forming a passageway; wherein by manually pulling down and positioning the fire blanket, the two movable door frames are moved toward a target vehicle, allowing the target vehicle to pass through the passageway, and the pivot smoothly releases the fire blanket to cover the target vehicle.

2. The portal fire blanket structure as described in claim 1, wherein the thrust-stopping mechanism includes a pair of ratchet wheels corresponding to the rotating shaft and a pawl pivotally mounted on the rotating shaft, the pawl being able to rotate with the rotating shaft, so that the pawl generates a thrust-stopping buffering phenomenon corresponding to the ratchet wheels.

3. The portal fire blanket structure as described in claim 1 or 2, wherein a bottom support is provided at the front end of the fire blanket.

4. The portal fire blanket structure as described in claim 1 or 2, further comprising a blanket-collecting mechanism, the blanket-collecting mechanism comprising an electrically driven drive gear, a driven gear, and a chain disposed between the drive gear and the driven gear, wherein the drive gear is pivotally mounted in the storage box, and the driven gear is disposed opposite to the rotating shaft, and the rotating shaft is provided with at least one recessed hole, and the driven gear is provided with a positioning hole, and a pin passes through the positioning hole and the recessed hole to enable the driven gear to move with the rotating shaft.

5. The portal fire blanket structure as described in claim 1 or 2, wherein the storage box contains a water tank with a water outlet and a channel for the fire blanket to pass through, and the bottom support of the fire blanket can be either tightly attached to or detached from the water outlet.

6. The portal fire blanket structure as described in claim 1 or 2, wherein a plurality of rollers are further provided below the two movable portal frames, the plurality of rollers providing displacement sliding for the movable portal frames.
