Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0029] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically describe the fire blanket and the electrical device with fire extinguishing function of this utility model.
[0030] Example 1
[0031] This embodiment provides a fire extinguishing blanket and an electrical device with fire extinguishing function.
[0032] Electrical devices with fire extinguishing capabilities include electrical appliances and fire blankets. The electrical appliances can be any of the following: charging piles, lithium battery packs, energy storage power stations, electric vehicles, industrial battery compartments, inverters, high-voltage cabinets, switchgear, energy storage cabinets, electrical control systems, or IT server rooms. Fire blankets are used in conjunction with electrical appliances. Normally, the fire blanket can be placed inside the appliance or near its exterior. In the event of a fire, the fire blanket is removed and laid over the entire appliance or at the point of ignition.
[0033] The following describes the detailed structure of the fire blanket in this embodiment, taking its application in electric vehicles (new energy vehicles) as an example.
[0034] Figure 1 This is a three-dimensional structural diagram of the fire blanket in Embodiment 1 of this utility model; Figure 2 This is a schematic diagram of the bottom blanket, the fire extinguishing part, and the top blanket in Embodiment 1 of this utility model.
[0035] like Figure 1 and Figure 2 As shown, the fire blanket 100 is a rectangular sheet, including a bottom blanket 10, a fire extinguishing section 20, and a top blanket 30 arranged sequentially from bottom to top.
[0036] Both the bottom blanket 10 and the top blanket 30 are made of basalt continuous fiber coated with special silicone rubber. Basalt continuous fiber is a durable industrial material with stable structure, fire resistance, high temperature resistance, good heat dissipation, corrosion resistance, and high strength. It can withstand high-temperature environments and will not melt or burn in flames, providing a good base material for fire blankets. Special silicone rubber has good temperature resistance and anti-aging properties, as well as good elasticity and flexibility. After being coated on the surface of basalt continuous fiber, it can enhance the overall performance of the fire blanket, making it stable in high-temperature environments, while also increasing its wear resistance, water resistance, and tear resistance.
[0037] In this embodiment, both the bottom blanket 10 and the top blanket 30 are 8m long and 6m wide. Both the bottom blanket 10 and the top blanket 30 have a uniform thickness in the surface direction.
[0038] Figure 3 This is a schematic diagram of the fire extinguishing rope in Embodiment 1 of this utility model. Figure 4 This is a photograph of the fire extinguishing rope in Embodiment 1 of this utility model.
[0039] like Figures 2-4 As shown, the fire extinguishing unit 20 includes multiple fire extinguishing ropes 21.
[0040] The fire extinguishing rope 21 includes a hollow rope-shaped body 211 and a fire extinguishing agent 212 filled inside the hollow rope-shaped body 211. The hollow rope-shaped body 211 is a commercially available special fiber fabric, which has the characteristics of high temperature resistance and corrosion resistance.
[0041] Extinguishing agent 212 is a commercially available fire extinguishing microcapsule or a commercially available aerosol fire extinguishing agent. Extinguishing agent 212 can self-ignite at high temperatures to extinguish fires.
[0042] Both ends of the hollow rope-shaped body 211 are sealed to prevent leakage of the extinguishing agent 212. When manufacturing the fire extinguishing rope 21, one end of the hollow rope-shaped body 211 can be sealed first, and then the extinguishing agent 212 can be filled through the other end. After filling, the other end is then sealed. The sealing method is existing technology, such as sealing with pressure-sensitive adhesive.
[0043] Figure 5 This is a schematic diagram of the distribution method of the fire extinguishing rope on the bottom blanket in Embodiment 1 of this utility model.
[0044] like Figure 5 As shown, a total of four fire extinguishing ropes 21 are installed on the bottom blanket 10. The four fire extinguishing ropes 21 are arranged in four rows along the length of the bottom blanket 10, with each fire extinguishing rope 21 forming an independent row. The fire extinguishing ropes 21 are parallel to the length of the bottom blanket 10. In this distribution, the length of each fire extinguishing rope 21 is 7.0m-7.5m.
[0045] Figure 6 This is a schematic diagram of the second distribution method of the fire extinguishing rope on the bottom blanket in Embodiment 1 of this utility model.
[0046] Furthermore, the distribution of the fire extinguishing rope 21 on the bottom blanket 10 can also be as follows: Figure 6 As shown. Figure 6 As shown, two extended fire extinguishing ropes 21 are installed on the bottom blanket 10, each with a length of 14.0m-16.0m. The two fire extinguishing ropes 21 are arranged in two rows along the length of the bottom blanket 10, with each fire extinguishing rope 21 forming an independent row. Each fire extinguishing rope 21 is arranged in an S-shape along the length of the bottom blanket 10.
[0047] The bottom blanket 10 and the top blanket 30 are sewn together, and a seam (not shown) is provided near the fire extinguishing rope 21, so that the bottom blanket 10, the fire extinguishing part 20 and the top blanket 30 can be combined together, and the specific distribution structure of the fire extinguishing rope 21 on the bottom blanket 10 can be maintained.
[0048] The bottom blanket 10 and the top blanket 30 are also provided with edging 40, which is set around the entire fire blanket 100 to prevent the fire extinguishing part 20 from being directly exposed.
[0049] The fire blanket 100 also has a ring handle 50 sewn at each of its four corners. The ring handles 50 allow for quick deployment of the fire blanket 100 while ensuring the user's safety.
[0050] The edging material 40, the ring handle material 50, and the stitching are all made of aramid fiber.
[0051] The manufacturing process of Fire Blanket 100 is as follows:
[0052] First, lay the bottom blanket 10 flat. Then, place multiple fire extinguishing ropes 21 on the bottom blanket 10 according to the predetermined arrangement. Next, lay the top blanket 30 flat on the bottom blanket 10 and the fire extinguishing ropes 21. Then, sew the fire extinguishing ropes 21 together with thread, and then attach the binding 40 and sew the binding to the bottom blanket 10 and the top blanket 30 with thread to complete the process.
[0053] The procedure for using the fire blanket 100 is as follows:
[0054] When an electric vehicle (new energy vehicle) experiences spontaneous combustion, a collision-induced fire, or a fire during charging, the user can pull the ring handle 50 to cover the entire electric vehicle (new energy vehicle) with the fire blanket 100 to isolate the fire source and prevent the fire from spreading to other parts of the vehicle or the surrounding environment. Simultaneously, the rope-type fire extinguisher can be directly aimed at the fire point to extinguish it, improving firefighting efficiency.
[0055] Example 2
[0056] This embodiment provides a fire blanket, which differs from the fire blanket 100 of Embodiment 1 only in the arrangement of the multiple fire extinguishing ropes 21a on the bottom blanket body 10. The other structures are the same as in Embodiment 1 and will not be described again here. Furthermore, for ease of explanation, the same symbols are used for structures identical to those in Embodiment 1, and the same descriptions are omitted in this embodiment.
[0057] Figure 7 This is a schematic diagram of the distribution of the fire extinguishing rope on the bottom blanket in Embodiment 2 of this utility model.
[0058] like Figure 7 As shown, in this embodiment, the fire extinguishing rope 21a is relatively short, about 1m in length, and a total of 28 fire extinguishing ropes 21a are provided on the bottom blanket 10. The 28 fire extinguishing ropes 21a are arranged in 4 rows and 7 columns, with 7 fire extinguishing ropes in each row connected in sequence by heat-sensitive wires 22 and pressure-sensitive adhesive, thus forming a straight line along the length direction of the bottom blanket 10.
[0059] Example 3
[0060] This embodiment provides a fire blanket, which differs from the fire blanket 100 of Embodiment 1 only in that the fire extinguishing part is composed of fire extinguishing discs instead of fire extinguishing ropes. Other structures are the same as in Embodiment 1 and will not be described again here. Furthermore, for ease of explanation, the same symbols are used for structures identical to those in Embodiment 1, and the same descriptions are omitted in this embodiment.
[0061] Figure 8 This is a schematic diagram of the distribution of fire extinguishing pads on the bottom blanket in Embodiment 3 of this utility model.
[0062] like Figure 8 As shown, in this embodiment, the fire extinguishing unit 20b includes multiple fire extinguishing discs 21b. The fire extinguishing discs 21b are rectangular, and the multiple fire extinguishing discs 21b are distributed in an equally spaced matrix on the bottom blanket 10.
[0063] The fire extinguishing disc 21b includes a housing and a fire extinguishing agent disposed within the housing. The fire extinguishing agent is a commercially available fire extinguishing microcapsule or a commercially available aerosol fire extinguishing agent. The housing is made of, for example, plastic or stainless steel.
[0064] Example 4
[0065] This embodiment provides a fire blanket, which differs from the fire blanket 100 of Embodiment 1 only in that its bottom and top blankets have inconsistent thicknesses in the planar direction. Other structures are the same as in Embodiment 1 and will not be described again here. Furthermore, for ease of explanation, the same reference numerals are used for structures identical to those in Embodiment 1, and the same descriptions are omitted in this embodiment.
[0066] Figure 9 This is a schematic diagram of the structure of the bottom blanket, the fire extinguishing part, and the top blanket in Embodiment 4 of this utility model; Figure 10 This is a schematic diagram of the top blanket and its thickened area in Embodiment 4 of this utility model.
[0067] like Figure 9 and Figure 10 As shown, the thickness of the first central portion 31 of the top blanket 30a of the fire blanket is greater than the thickness of the rest of the blanket; that is, the first central portion 31 serves as a thickened area of the top blanket 30a. Specifically, the outer surface of the first central portion 31 protrudes beyond the outer surface of the rest of the blanket, while the inner surface of the entire top blanket 30a (the surface in contact with the fire extinguishing part 20) is flush with it. The first central portion 31 is rectangular with rounded corners.
[0068] The thickness of the second central portion 11 of the bottom blanket 10a of the fire blanket is greater than the thickness of the rest of the blanket; that is, the second central portion 11 serves as a thickened area of the bottom blanket 10a. Specifically, the outer surface of the second central portion 11 protrudes beyond the outer surface of the rest of the blanket, while the inner surface of the entire bottom blanket 10a (the surface in contact with the fire extinguishing part 20) is flush with it. The second central portion 11 is rectangular with rounded corners.
[0069] The role and effect of the embodiments
[0070] This embodiment provides a fire blanket and an electrical device with fire extinguishing function. The fire blanket includes a bottom blanket body, a fire extinguishing part, and a top blanket body arranged sequentially from bottom to top. The fire extinguishing part includes multiple evenly and spacedly distributed fire extinguishing ropes or multiple evenly and spacedly distributed fire extinguishing discs. The fire extinguishing ropes are filled with fire extinguishing microcapsules or aerosol fire extinguishing agents, and the fire extinguishing discs contain fire extinguishing microcapsules or aerosol fire extinguishing agents. Therefore, this fire blanket can be used in electrical appliances such as charging piles, lithium battery power packs, energy storage power stations, electric vehicles, industrial battery compartments, inverters, high-voltage cabinets, switch cabinets, energy storage cabinets, electrical control systems, and IT server rooms, effectively ensuring the timeliness and safety of fire extinguishing.
[0071] Furthermore, because the fire blanket is a rectangular sheet measuring 8m x 6m, it can quickly cover the entire electric vehicle (new energy vehicle) in the event of an initial fire, rapidly isolating the fire source, preventing the fire from spreading, buying time for subsequent firefighting, and reducing the damage to the vehicle and the surrounding environment.
[0072] Furthermore, since both the bottom and top blankets are made of basalt continuous fiber coated with special silicone rubber, basalt continuous fiber is a durable industrial material with stable structure, fire resistance, high temperature resistance, good heat dissipation, corrosion resistance, and high strength. It can withstand high-temperature environments and will not melt or burn in flames, providing a good base material for fire blankets. Special silicone rubber has good temperature resistance and anti-aging properties, as well as good elasticity and flexibility. After being coated on the surface of basalt continuous fiber, it can enhance the overall performance of fire blankets, making them stable in high-temperature environments, while also increasing their wear resistance, water resistance, and tear resistance.
[0073] Furthermore, because the bottom blanket and the top blanket are sewn together, and there are seams near the fire extinguishing rope and / or fire extinguishing disc, the fire extinguishing rope can be securely positioned at a predetermined location between the bottom blanket and the top blanket.
[0074] Furthermore, because the fire extinguishing rope comprises a hollow rope-shaped body and fire extinguishing microcapsules or aerosol fire extinguishing agents filled within the hollow rope-shaped body, with both ends of the hollow rope-shaped body sealed, and the hollow rope-shaped body being made of special fiber fabric with good high temperature resistance and corrosion resistance, and while well preserving its internal contents (fire extinguishing microcapsules or aerosol fire extinguishing agents), it does not affect the self-ignition reaction of these contents when a fire occurs.
[0075] Furthermore, because multiple fire extinguishing ropes are arranged in multiple rows along the length of the fire blanket, with each fire extinguishing rope forming an independent row, and the fire extinguishing ropes are parallel to the length of the fire blanket or arranged in an S-shape along the length of the fire blanket, this arrangement can meet the fire extinguishing needs of large areas and has a good fire extinguishing effect.
[0076] Furthermore, multiple fire extinguishing ropes are distributed in m rows and n columns, where m ≥ 2 and n ≥ 2. The n fire extinguishing ropes in each row are connected sequentially by heat-sensitive wires. This arrangement ensures that each fire extinguishing rope is not excessively long (approximately 6m), but rather shorter (approximately 1m). This facilitates the filling of the hollow rope-shaped body with fire extinguishing microcapsules or aerosol extinguishing agents, thus simplifying the manufacturing process of the fire extinguishing ropes. Connecting the n fire extinguishing ropes sequentially by heat-sensitive wires in each row ensures a uniform and consistent self-ignition extinguishing effect throughout the row, achieving the same extinguishing effect as if a single long fire extinguishing rope (approximately 6m) were used in a row.
[0077] Furthermore, because the thickness of the central part of the bottom and top blankets is greater than the thickness of the rest, the central part can withstand high temperatures while the rest of the blanket can be less resistant, thus minimizing the overall weight of the fire blanket.
[0078] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
[0079] For example, the arrangement of fire extinguishing ropes on the bottom blanket can also be radial, starting from the center, and so on.
