[0032] Embodiment 1

[0033] This embodiment provides an automatic fire prevention facility for exterior windows of a residence, including a fireproof rolling curtain 1, a guide rail groove 2, a storage device 3, a thermal fuse 4, and a weight pulling rope assembly 5, where:

[0034] As shown in the attached Figure 2 and the attached Figure 3 The fireproof rolling curtain 1 includes a reel 1.1, end codes 1.2 provided at both ends of the rotating shaft, a fixator 1.3 for fixing the end codes to the wall, curtain sheets 1.4 wound around the reel, and a bottom shaft 1.5 provided at the bottom of the curtain sheets. The curtain sheets are made of fireproof materials. From the exterior, the installation state of the fireproof rolling curtain is as shown in the attached Figure 3 As shown, from the interior, as shown in the attached Figure 1 When installing the fireproof rolling curtain, there is a prompt on the curtain sheet: it is necessary to ensure that the rolling curtain is in the upper storage position.

[0035] The guide rail groove 2 is provided on both sides of the exterior window, and its functions are: to limit the curtain sheet and prevent the curtain sheet from fluttering due to the impact of high-temperature hot air, and it can effectively block the intrusion of smoke and fire. The guide rail groove can be made of aluminum profiles.

[0036] As shown in the attached Figure 3 and the attached Figure 4As shown, the release device 3 is installed on both sides of the outer window, and the release device extends out of the track groove to support the bottom shaft 1.5 of the fireproof roller shutter 1. Preferably, the release device 3 of this embodiment includes a mounting frame 3.1 and an ear-shaped spring piece 3.2 fixedly installed on the inner side of the mounting frame 3.1, and the ear-shaped spring piece 3.2 is made of spring steel, and a connection hole connected to the pull rope of the heavy hammer pull rope assembly 5 is provided on the ear-shaped spring piece 3.2. The ear-shaped spring piece can release the bottom shaft of the protective roller shutter in the form of body deformation by the pulling force of the pull rope, so that the fireproof roller shutter is closed under the action of its own weight.

[0037] As attached Figure 7 As shown, the thermal fuse 4 is in the shape of a long strip, and includes a paraffin body 4.1 and a chemical fiber line 4.2 wound in the paraffin body 4.1. When manufacturing, paraffin is used as the raw material, the chemical fiber line is repeatedly folded, and then the molten wax is cast into a light strip body, with both ends of the chemical fiber line exposed from the paraffin body, one end of which is fixed to the bracket of the wall, and the other end is connected to the weight pull rope assembly.

[0038] As attached Figure 2 , 4 As shown in Figures 5 and 6, the weight pull rope assembly 5 includes a bracket 5.1, a weight 5.2, a pull rope 5.3 and a conduit 5.4. The bracket 5.1 is fixed to the wall. One end of the pull rope 5.3 is connected to the device to be released 3, and the other end passes through the conduit 5.4 arranged on both sides and the bottom of the outer window and then passes through the bracket 5.1 to connect the weight 5.2 and the thermal fuse 4. This design allows the device to be released to be pulled under the gravity of the weight in the weight pull rope assembly after the thermal fuse is melted by heat, so that the device to be released is deformed and the bottom shaft of the fireproof roller shutter is released. The fireproof roller shutter is closed under its own weight, thereby realizing that the fireproof roller shutter is automatically closed when the fire spreads to the outer window. Preferably, the pull rope is made of fireproof material, preferably steel wire rope, which is not only fireproof but also has good wear resistance and long service life. In this embodiment, the pull rope is inserted into the conduit, which can not only use the conduit for guiding and limiting, but also use the conduit for protection, further improving the service life of the pull rope.

[0039] In this embodiment, the bottom shaft of the fireproof roller shutter is placed on the release device. When the fire spreads to the outer window, the thermal fuse is melted by the heat and releases the weight. The weight pulls the release device under the action of its own weight, causing the release device to deform. The bottom shaft is separated from the deformed release device and automatically closes the outer window under the action of its own weight, thereby isolating the invasion of fire and smoke, effectively preventing the fire from spreading further, and can autonomously achieve fire isolation without the need for personnel supervision.

[0040] Embodiment 2

[0041] As attached Figure 2 and attached Figure 5As shown, the first embodiment is repeated. In this embodiment, a fireproof protective shed 6 is further fixedly installed on the wall below the outer window. The thermal fuse 4 and the weight pull rope assembly 5 are both arranged inside the protective shed 6, specifically on the mounting bracket of the protective shed. The protective shed in this embodiment can, on the one hand, collect the smoke and flames ejected from the lower window, causing the thermal fuse to quickly blow. At the same time, it can also effectively block the upward spread of smoke and flames, delaying the time for the rolling curtain to fall and close.

[0042] As shown in the attached Figure 5 figure, the protective shed 6 includes a mounting bracket 6.1 fixed to the wall and a protective plate 6.2 laid on the mounting bracket. The protective plate can be made of steel plate. Further, the protective plate 6.2 of the protective shed 6 directly above the thermal fuse 4 is provided with a movable protective plate 6.3 for replacing the thermal fuse. This design facilitates the replacement of the thermal fuse. During specific operation, when the fire hazard risk of the outer window is eliminated, the household only needs to return the fireproof rolling curtain to the standby device, open the movable protective plate to replace the thermal fuse, and then close the movable protective plate after replacement. Specifically, the movable protective plate 6.3 can adopt a flip type or a sliding cover type structure and is provided with a snap type or a bolt type fixing structure.

[0043] It should be noted that: The outer window of the residence applicable to this application is preferably an inward-opening window to prevent interference with the closing of the fire protection facilities after the outward-opening window is opened.

[0044] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
