Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment technology, specifically to a portable fire-fighting device. Background Technology

[0002] With the acceleration of urbanization, the fire risk in high-rise buildings, large shopping malls, and residential homes is increasing. In the early stages of a fire, rapid and effective firefighting measures are crucial.

[0003] Fire blankets, as a simple initial fire prevention device, can cover the fire source to isolate the flames and quickly extinguish open flames. They can also be used as protective items for timely escape, wrapped around the escapee during the escape process to protect them.

[0004] However, traditional fire blankets are typically made of materials such as asbestos or fiberglass. While these materials offer good fire resistance, they are heavy and inconvenient to carry. When using asbestos fire blankets, the extremely fine asbestos fibers can easily be inhaled and deposited in the lungs, causing lung disease. When using fiberglass fire blankets, the fine glass fibers may penetrate the skin, causing a stinging sensation. Therefore, traditional fire blankets may pose a potential health hazard during use. Utility Model Content

[0005] The purpose of this application is to provide a portable fire protection device that solves the problems of traditional fire blankets being inconvenient to carry and potentially causing harm to the human body.

[0006] The technical solution adopted by this application to solve its technical problem is:

[0008] Furthermore, both the first fire-retardant coating and the second fire-retardant coating include a silicate coating or a phosphate coating.

[0009] Furthermore, both the first fireproof outer layer and the second fireproof outer layer comprise aramid fiber fabric.

[0010] Furthermore, the thickness of both the first fireproof outer layer and the second fireproof outer layer is 0.5 to 1.5 mm.

[0011] Furthermore, the melamine foam has a thickness of 3–10 mm and a density of 8–10 kg / m³. 3 .

[0040] See Figure 1 , Figure 2 , Figure 3The portable fireproof device provided in this application includes a fireproof blanket 10 and a storage component 20 for storing the fireproof blanket 10. The fireproof blanket 10 includes a first fireproof outer layer 101, a first fireproof coating 102, a fireproof base layer 103, a second fireproof coating 104, and a second fireproof outer layer 105, which are stacked in sequence. The fireproof base layer 103 includes melamine foam.

[0041] See Figure 1 The fire blanket 10 can be rectangular, circular, triangular, or parallelogram in shape, and can be cut to size as needed. See also Figure 2 The fire blanket 10 comprises, from bottom to top, a first fireproof outer layer 101, a first fireproof coating 102, a fireproof base layer 103, a second fireproof coating 104, and a second fireproof outer layer 105, stacked sequentially. The fireproof base layer 103, serving as the main fireproof layer, is made of melamine foam; the melamine foam has a thickness of 3–10 mm and a density of 8–10 kg / m³. 3 Due to its thinness and lightness, melamine foam can be folded freely. Melamine foam exhibits good stability at high temperatures, is not easily melted or burned, and possesses excellent heat insulation properties, effectively blocking flames and heat. Simultaneously, melamine foam has a low density and is lightweight, making it easy to handle and store during use. When exposed to open flames, the surface of melamine foam slightly ignites and chars, but it self-extinguishes upon removal of the flame. During this charring process, nitrogen and carbon dioxide are released, enhancing its fire extinguishing performance, and no toxic substances are produced, improving safety during firefighting. The first fire-retardant coating 102 and the second fire-retardant coating 104 are respectively applied to both sides of the fire-retardant base layer 103, further improving the fire resistance of the base layer 103. The first fire-retardant outer layer 101 and the second fire-retardant outer layer 105 not only further enhance the fire resistance of the fire-retardant base layer 103 but also protect the fire-retardant base layer 103 and its fire-retardant coating from physical damage such as tearing and abrasion, thereby extending its service life. See also... Figure 3 The storage component 20 has a storage cavity, and the fire blanket 10 can be stored in the storage cavity of the storage component 20 after being folded.

[0042] The portable fireproof device provided in this application embodiment uses melamine foam to make the fireproof base layer 103 of the fireproof blanket 10, with a density of 10 kg / m³. 3Calculations show that a 1.5m × 1.5m × 3mm melamine foam sheet weighs 0.054kg, roughly the weight of an egg. This significantly reduces the weight of the fire blanket 10, making it more convenient to carry, transport, and store. Compared to existing asbestos and fiberglass fire blankets, melamine foam does not produce fine fibers during use, avoiding potential harm to the human body. Melamine foam does not produce toxic substances when exposed to open flames, and its production cost is relatively low, resulting in higher safety and lower manufacturing costs for the fire blanket 10. By incorporating a storage component 20, the fire blanket 10 can be folded and stored within it, protecting it and improving its portability, ensuring it can be quickly retrieved for use in emergencies.

[0043] In some embodiments, both the first fire-retardant coating 102 and the second fire-retardant coating 104 include silicate coatings or phosphate coatings. When the fire blanket 10 is exposed to an open flame, the silicate or phosphate can interrupt the chain reaction in the combustion process, thereby inhibiting the continued combustion. Simultaneously, when the silicate or phosphate decomposes under heat, it absorbs a large amount of heat, lowering the temperature of the coating and the protected substrate, delaying the time it takes to reach its ignition point, preventing further flame spread, and improving the overall fire-retardant performance of the fire blanket 10. For example, taking phosphate as an example, the process of applying a coating to melamine foam is as follows: first, prepare a 5%–30% aqueous solution of dihydrogen phosphate, with 25% being optimal. Immerse the melamine foam in this aqueous solution for 0.5–1 hour. If a thicker coating is required, the immersion time can be extended. After immersion, remove the melamine foam and dry it in an environment not exceeding 70°C. Fire-retardant coatings of other materials can also be applied using the above method.

[0044] In some embodiments, both the first fire-resistant outer layer 101 and the second fire-resistant outer layer 105 comprise aramid fiber fabric. Aramid fiber fabric possesses excellent flame-retardant and heat-resistant properties, with a limiting oxygen index greater than 28. Its flame-retardant characteristics are determined by its own chemical structure, making it a permanently flame-retardant material that will not lose its flame-retardant properties due to usage time or washing cycles. Aramid fiber fabric also exhibits good thermal stability, allowing continuous use at 205°C without melting or dripping, and only begins to char at temperatures above 370°C. The first fire-resistant outer layer 101, the fire-resistant base layer 103, and the second fire-resistant outer layer 105 can be connected by sewing. This sewing not only ensures a strong bond between the layers but also provides additional strength and durability to a certain extent. Furthermore, the edges of the first fire-resistant outer layer 101 and the second fire-resistant outer layer 105 are edge-bound to prevent exposure and wear of the fire-resistant base layer 103. Of course, the first fireproof outer layer 101, the fireproof base layer 103, and the second fireproof outer layer 105 can also be connected by adhesive or other methods, and no specific limitation is made here. The thickness of the first fireproof outer layer 101 and the second fireproof outer layer 105 is 0.5 to 1.5 mm, to avoid being too thin and easily damaged, or too thick and affecting the folding performance of the fire blanket 10; the thickness of the first fireproof outer layer 101 and the second fireproof outer layer 105 is preferably 1 mm.

[0045] In some embodiments, see Figure 1 The surface of the fire blanket 10 is provided with at least two handles 30. By providing the handles 30, it is convenient for workers to hold the handles 30 to operate the fire blanket 10. For example, the handles 30 can be sheet-like or block-like structures, and are fixed to the surface of the fire blanket 10 by sewing.

[0046] Storage component 20 may include a storage bag. See also: [link to embodiments]. Figure 3 The storage component 20 includes a bottle body 201 and a cap 202 for covering the bottle body 201, forming a storage cavity between the bottle body 201 and the cap 202. The fire blanket 10 is used to store the fire blanket 10 in the storage cavity. For example, the bottle body 201 is cylindrical and can be made of heat-resistant, low-density materials such as polyimide, polyphenylene sulfide, polycarbonate, and carbon fiber composite materials, which are unaffected by high-temperature environments and are lightweight. The height of the bottle body 201 is between 30cm and 50cm, and the inner diameter opening is between 15cm and 20cm, specifically determined by the size of the fire blanket 10.

[0047] In some embodiments, ventilation holes are provided on the wall of the bottle body 201. Exemplarily, at least two ventilation holes are provided, each with a diameter of 0.5 mm. By providing ventilation holes, air circulation between the storage cavity and the outside of the bottle body 201 can be ensured, reducing moisture accumulation and thus keeping the fire blanket 10 stored in the storage cavity dry. This improves the safety and reliability of the fire blanket 10 storage and ensures that it can perform its best fire-resistant function when needed.

[0048] In some embodiments, see Figure 3 A latch 203 is provided on the outer wall of the bottle body 201. Because of its flexibility and thinness, the fire blanket 10 is easy to fold and roll up for storage in the storage cavity. Due to its light weight, the fire blanket 10 can be easily carried by locking it to the body using the latch 203 after being stored in the storage cavity. The latch 203 can be fixedly connected to the bottle body 201 or movably connected. For example, a connecting shaft 204 can be fixed at the middle position of the outer wall of the bottle body 201, and the latch 203 can be connected to and rotate around the connecting shaft 204.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this application and within the spirit and principles of this application shall still fall within the protection scope of the technical solution of this application.
