Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fire blankets, and in particular to a multi-layer gradient fire extinguishing device for inhibiting heat spread. Background Technology
[0002] Electrical fires are a constant risk in electrical facilities (such as distribution boxes and substations), automobiles (especially battery compartments), and charging stations. These fires are typically characterized by rapid ignition, rapid spread, easy reignition, and the presence of toxic fumes. If they do not receive timely and effective control, they can easily cause significant property damage or even casualties.
[0003] In existing technologies, traditional fire blankets mainly extinguish fires by physically isolating oxygen. This has limited effectiveness against large-area, high-intensity, or three-dimensional fires. They do not have the ability to release extinguishing agents and rely solely on isolation. Once the flames break through or the temperature of the wrapped object becomes too high and ignites the blanket itself, the protection fails. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the related art.
[0005] Therefore, the purpose of this utility model is to propose a multi-layer gradient fire extinguishing device for inhibiting the spread of heat. It adopts an outer sleeve containing a fire extinguishing agent added to the fire blanket. When the fire extinguishing agent in the outer sleeve is heated, it releases fire extinguishing gas, thereby inhibiting the spread of fire and controlling the fire in a timely manner.
[0006] To achieve the above objectives, this utility model proposes a multi-layer gradient fire extinguishing device for inhibiting heat spread, comprising a fire-resistant layer, an adhesive layer, a fire extinguishing layer, an inhibition layer, and an outer protective layer, wherein the adhesive layer is coated on the opposite end faces of the fire-resistant layer and the fire extinguishing layer; the fire extinguishing layer is disposed on the fire-resistant layer; the inhibition layer is disposed on the top wall of the fire extinguishing layer; and the outer protective layer is disposed on the top wall of the inhibition layer.
[0007] This utility model relates to a multi-layer gradient fire extinguishing device for suppressing the spread of heat. It employs an outer sleeve containing a fire extinguishing agent added to the fire blanket. When the fire extinguishing agent in the outer sleeve is heated, it releases fire extinguishing gas, thereby suppressing the spread of fire and controlling the fire in a timely manner.
[0008] In addition, the multi-layer gradient fire extinguishing device for suppressing heat spread proposed in the above application may also have the following additional technical features:
[0009] Specifically, the fire extinguishing layer includes a woven sleeve, pre-drilled holes, an adhesive layer, and a fire extinguishing component. The woven sleeve is disposed on the fire-resistant layer. The pre-drilled holes are in multiple sets, and multiple sets of pre-drilled holes are arranged in a linear array on the woven sleeve. The adhesive layer is coated on the woven sleeve. The fire extinguishing component is inserted into the pre-drilled holes.
[0010] Specifically, the fire extinguishing device includes an outer tube and a fire extinguishing agent, wherein the outer tube is inserted into the reserved hole; and the fire extinguishing agent is filled inside the outer tube.
[0011] Specifically, the inhibition layer includes a textile cover and an inhibitor, wherein the textile cover is disposed on the textile cover; the inhibitor is in multiple groups, and multiple groups of the inhibitor array are disposed on the textile cover.
[0012] Specifically, the outer protective layer includes a surface protective sleeve, a pressing edge, and a pull cord, wherein the surface protective sleeve is disposed on the textile sleeve; the pressing edge is annularly disposed on the surface protective sleeve; and the pull cord is disposed on the pressing edge.

Detailed Implementation
[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the appended spirit and connotation.
[0022] The following description, in conjunction with the accompanying drawings, describes a multi-layer gradient fire extinguishing device for suppressing heat spread according to an embodiment of the present invention.
[0023] like Figure 1-5 As shown, the multi-layer gradient fire extinguishing device for suppressing heat spread according to an embodiment of the present invention includes a fire-resistant layer 10, an adhesive layer 20, a fire extinguishing layer 30, an suppression layer 40, and an outer protective layer 50.
[0024] The adhesive layer 20 is coated on the opposite end faces of the fire-resistant layer 10 and the fire-extinguishing layer 30. The fire-extinguishing layer 30 is disposed on the fire-resistant layer 10, the suppression layer 40 is disposed on the top wall of the fire-extinguishing layer 30, and the outer protective layer 50 is disposed on the top wall of the suppression layer 40.
[0025] It should be noted that both the adhesive layer 20 and the adhesive layer 303 use adhesive solvents. The fire extinguishing layer 30 is then bonded to the fire-resistant layer 10 through the adhesive layer 20. The fire-resistant layer 10 is a blanket woven from flame-retardant rope. The flame retardant in the fire extinguishing layer 30 is an aerosol, which is filled in the outer sleeve 3041 and then inserted into the blanket.
[0026] In one embodiment of this utility model, such as Figure 3 As shown, the fire extinguishing layer 30 includes a woven sleeve 301, a reserved hole 302, an adhesive layer 303, and a fire extinguishing component 304.
[0027] The braided sleeve 301 is installed on the fire-resistant layer 10, the reserved holes 302 are in multiple sets, and the multiple sets of reserved holes 302 are arranged in a linear array on the braided sleeve 301. The adhesive layer 303 is coated on the braided sleeve 301, and the fire extinguishing component 304 is inserted into the reserved hole 302.
[0028] It should be noted that the braided sleeve 301 is a combustible sleeve layer, and the braided sleeve 301 has multiple reserved holes 302. The fire extinguishing component 304 is inserted into the reserved holes 302. Then, when the outer protective layer 50 and the suppression layer 40 burn to the fire extinguishing component 304, the fire extinguishing component 304 will burn through and extinguish the fire.
[0029] Furthermore, to prevent further combustion, the adhesive layer 303 is made of a non-combustible agent, such as sealing glue.
[0030] In one embodiment of this utility model, such as Figure 4 As shown, the fire extinguishing component 304 includes an outer casing 3041 and a fire extinguishing agent 3042.
[0031] The outer sleeve 3041 is inserted into the reserved hole 302, and the extinguishing agent 3042 is filled inside the outer sleeve 3041.
[0032] It should be noted that the outer sleeve 3041 is inserted into the reserved hole 302, while the extinguishing agent 3042 is an aerosol. The outer sleeve 3041 is in units of one meter, and the outer sleeve 3041 is connected to each other according to the required length of the outer sleeve 3041, and then inserted into the reserved hole 302.
[0033] Furthermore, the outer sleeve 3041 is a flexible tube, and rigid sleeves are provided at both ends of the outer sleeve 3041 to facilitate the insertion of the outer sleeve 3041 into the reserved hole 302.
[0034] In one embodiment of this utility model, such as Figure 5 As shown, the inhibition layer 40 includes a textile cover 401 and an inhibitor 402.
[0035] Among them, the textile sleeve 401 is set on the braided sleeve 301, and the inhibitor 402 is in multiple groups, with an array of multiple groups of inhibitor 402 set on the textile sleeve 401.
[0036] It should be noted that the textile cover 401 can be made of common and practical braided rope, while the inhibitor 402 is made of activated carbon particles. The inhibitor 402 falls off as the textile cover 401 burns and is absorbed by the smoke generated during fire extinguishing.
[0037] In one embodiment of this utility model, such as Figure 2 As shown, the outer protective layer 50 includes a surface protective sleeve 501, a pressing edge portion 502, and a pull cord 503.
[0038] The surface protective sleeve 501 is mounted on the textile sleeve 401. The surface protective sleeve 501 can be a thin layer of flammable material such as flammable fabric, and is fixed to the textile sleeve 401 by adhesive bonding, sewing, or other methods. The pressing edge 502 is annularly mounted on the surface protective sleeve 501. The pressing edge 502 can be made of either flammable or non-flammable material, preferably non-flammable, such as flame-retardant fabric. It is then sewn into a hollow tubular structure and fixed to the surface protective sleeve 501 by adhesive bonding, sewing, or other methods. A pull cord 503 is mounted on the pressing edge 502.
[0039] It should be noted that the outer edge 502 of the outer protective layer 50 is also filled with gravel. The gravel causes the outer edge of the fire blanket to fall down without being pushed up by the rising flames. The pull rope 503 is used to install and fix the fire blanket when it is installed externally.
[0040] Specifically, the steps for using a multi-layer gradient fire blanket are as follows: The fire blanket is installed on a distribution box, vehicle, or charging station via a pull cord 503. When a fire breaks out, the flames burn through the surface protective sleeve 501 and the textile sleeve 401. Subsequently, the fire spreads to the woven sleeve 301, burning through the woven sleeve 301 and the outer sleeve 3041. The extinguishing agent 3042 in the outer sleeve 3041 then releases extinguishing gas upon heating, which extinguishes the flames. Furthermore, the fire-resistant layer 10 covers the flames, preventing the rapid spread of the fire.
[0041] In summary, the multi-layer gradient fire extinguishing device for suppressing the spread of heat in this embodiment of the utility model adopts an outer sleeve containing a fire extinguishing agent added to the fire blanket. When the fire extinguishing agent in the outer sleeve is heated, it releases fire extinguishing gas, thereby suppressing the spread of fire and controlling the fire in a timely manner.
[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
