Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing patches, in particular to a self-exciting heptafluoropropane capsule active fire extinguishing patch. Background Art

[0002] When the fire extinguishing patch encounters a high temperature environment, such as a fire, the internal heptafluoropropane capsule will be activated, and the heptafluoropropane will then be released and enter the fire area. Due to the large molecular weight of heptafluoropropane, some of the bonds in the molecules break and absorb heat during fire extinguishing, which has a certain effect of inhibiting free radicals and other combustion active groups and reducing the temperature. At the same time, heptafluoropropane is sprayed into the protected area in a nearly liquid form, quickly vaporizes and absorbs a large amount of heat, reducing the temperature in the protected area and around the flame. In addition, the heptafluoropropane vaporization process is rapid, and the concentration in the protected area increases rapidly, which can quickly reduce the partial pressure concentration of oxygen, reduce the burning speed of the flame, and then gradually reduce the oxygen concentration to below the combustible concentration, achieving the effect of extinguishing the fire.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] For examples, see Figure 1-Figure 4As shown, the present embodiment provides a self-exciting heptafluoropropane capsule active fire extinguishing patch, comprising an outer shell 1, wherein the outer shell 1 contains a fire extinguishing patch. When the fire extinguishing patch encounters a high temperature environment, the heptafluoropropane capsule inside the fire extinguishing patch will be automatically activated, and the heptafluoropropane will then be released and enter the fire area to extinguish the fire source. A bottom patch 2 is provided on one side of the outer shell 1, and a release paper 3 is provided on one side of the bottom patch 2. After the release paper 3 is torn off, the bottom patch 2 can be attached to a position requiring fire protection. Since a U-shaped plate 4 is provided on the other side of the bottom patch 2, fixing mechanisms are installed on both sides of the U-shaped plate 4. A symmetrical positioning groove 12 is provided on one side of the outer shell 1. The fixing mechanism fixes the outer shell 1 by snapping with the positioning groove 12. At the same time, the fixing mechanism makes it easier to replace the outer shell 1.

[0024] Among them, the fixing mechanism includes a slide plate 6, which is slidably set in a slide groove 5 opened in the U-shaped plate 4, and one end of the slide plate 6 extends out of the slide groove 5 and is slidably connected to the outer wall of the slide groove 5. A positioning plate 7 is set on one side of the slide plate 6. The positioning plate 7 is engaged with the positioning groove 12 to fix the shell 1 and improve the stability of the shell 1.

[0025] Furthermore, a spring 8 is connected between the inner wall of the slide groove 5 and the slide plate 6. The spring 8 pushes the slide plate 6 so that the slide plate 6 and the positioning plate 7 are firmly clamped in the positioning groove 12. When the shell 1 needs to be replaced, the slide plate 6 is pinched inward so that the slide plate 6 squeezes the spring 8 and the positioning plate 7 is away from the positioning groove 12, which makes it easy to replace the shell 1.

[0026] Furthermore, a buckle rod 9 is connected to one end of the slide plate 6, and one end of the buckle rod 9 is plugged into and matched with a socket 13 provided on both sides of the shell 1. At the same time, a spring 2 10 is connected between the buckle rod 9 and the side wall of the U-shaped plate 4. The spring 2 10 tightens the buckle rod 9 so that the buckle rod 9 is clamped in the socket 13, thereby further improving the stability of the shell 1.

[0027] It is worth mentioning that a limit member 11 is provided on the U-shaped plate 4 on both sides of the slide groove 5. The limit member 11 is slidably connected to one end of the buckle rod 9, making the buckle rod 9 more stable, and pushing one end of the buckle rod 9 inward can make the other end of the buckle rod 9 away from the socket 13, making it convenient to push the buckle rod 9 while pushing the slide plate 6, thereby increasing the speed of replacing the shell 1.

[0028] When the utility model is used for the self-exciting heptafluoropropane capsule active fire extinguishing sticker, when it is necessary to replace the expired shell 1, first push one end of the buckle rod 9 inward to make the other end of the buckle rod 9 away from the insertion hole 13, and at the same time pinch the two slide plates 6 inward to make the positioning plate 7 away from the positioning groove 12. At this time, the shell 1 is not fixed and slides downward. After the shell 1 is separated from the bottom sticker 2, the new shell 1 can be fixed in the U-shaped plate 4.
