Abstract
Description
Technical Field
[0001] The present invention relates to the field of fire protection technology, in particular to a multi-channel fire extinguishing blanket and a fire extinguishing device. Background Art
[0002] The fire-extinguishing wrap blanket is a fabric woven from glass fiber, ceramic wool and other materials that have been specially treated. It is assembled and compounded with fire extinguishing agents. It can isolate heat sources and flames, absorb heat and cool down, and isolate oxygen to achieve the effect of extinguishing fire.
[0003] However, in actual applications, since traditional fire extinguishing blankets are tightly wrapped and sealed on the outer surface of equipment, cables, pipelines, and other components, and the location of the fire point is uncertain, and the amount of traditional fire extinguishing materials coated on the fire extinguishing blankets is limited; resulting in a slow fire extinguishing speed of the traditional fire extinguishing blankets, and thus unable to achieve a good fire extinguishing effect, especially for active fire extinguishing blankets, such as perfluorohexanone fire extinguishing blankets, the fire extinguishing speed is even slower.
[0004] To this end, a new type of fire extinguishing technology has appeared on the market. Chinese patent number CN218076081U discloses a fire blanket. The first film layer (1) and the second film layer (2) are formed into irregular bulges on their surfaces, so that a heat dissipation gap is reserved between the irregular bulge shell surface of the fire blanket and the thermal runaway protection shell of the new energy vehicle battery pack, that is, multiple first channels are formed, thereby improving the rapid fire extinguishing effect of the fire blanket.
[0005] Although the first channel added to the fire blanket can speed up the fire extinguishing speed of the fire blanket, the first channel is a one-way flow, which means that the fire blanket can only flow in one direction, and the fire blanket cannot achieve a rapid fire extinguishing effect. Utility Model Content
[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a multi-channel fire extinguishing blanket and fire extinguishing device that is beneficial to the heat dissipation of the protected object, plays a certain protective role on the protected object, and improves the superimposed vaporization release reaction of multiple active fire extinguishing units to kill the temperature or flame in the initial stage and reduce the probability of fire.
[0007] The purpose of this disclosure is achieved through the following technical solutions:
[0008] A multi-channel fire extinguishing wrapping blanket comprises a blanket body, wherein the multi-channel fire extinguishing wrapping blanket further comprises a plurality of active fire extinguishing groups, wherein each of the active fire extinguishing groups is adhered at intervals in the width direction of the wrapping surface of the blanket body, and a plurality of first fire extinguishing release sub-channels are formed in the width direction of the wrapping surface of the blanket body; each of the active fire extinguishing groups comprises a plurality of fire extinguishing units, wherein each of the fire extinguishing units is adhered at intervals in the length direction of the wrapping surface of the blanket body, and a plurality of second fire extinguishing release sub-channels are formed in the length direction of the wrapping surface of the blanket body; each of the first fire extinguishing release sub-channels is interconnected with each of the second fire extinguishing release sub-channels to form a fire extinguishing release flow cavity.
[0009] In one embodiment, a first intersection is formed at the intersection where each of the second fire extinguishing release sub-channels is connected to a first fire extinguishing release sub-channel.
[0010] In one of the embodiments, each of the fire extinguishing units is further formed with a third fire extinguishing release sub-channel, and both ends of the third fire extinguishing release sub-channel are respectively connected to the adjacent first fire extinguishing release sub-channel and the second fire extinguishing release sub-channel.
[0011] In one embodiment, each of the fire extinguishing units is further formed with a fourth fire extinguishing release sub-channel, the fourth fire extinguishing release sub-channel is staggeredly connected with the third fire extinguishing release sub-channel to form a second intersection, and the two ends of the fourth fire extinguishing release sub-channel are respectively connected with the adjacent first fire extinguishing release sub-channel and the second fire extinguishing release sub-channel.
[0012] In one embodiment, each of the fire extinguishing units has a shape of one or both of a polygon and a circle.
[0013] In one embodiment, the fire extinguishing unit is one or two of a parallelogram, a rectangle, a square and a triangle.
[0014] In one embodiment, each of the fire extinguishing units is a solid aerogel perfluorohexanone fire extinguishing sheet; and / or,
[0015] A preset gap is formed between the edges of the covering surface of the blanket body and each of the active fire extinguishing groups.
[0016] In one embodiment, the blanket body is one of an aramid blanket, a high-silica glass fiber blanket or an aluminum foil composite glass fiber blanket.
[0017] In one embodiment, an adhesive layer is formed between each of the fire extinguishing units and the wrapped surface of the blanket body, and the adhesive layer is an epoxy adhesive layer.
[0018] A fire extinguishing device comprises the multi-channel fire extinguishing wrap blanket described in any one of the above embodiments.
[0019] Compared with the prior art, the present invention has at least the following advantages:
[0020] 1. Since a plurality of active fire extinguishing groups are adhered at intervals in the width direction of the wrapping surface of the blanket body, a plurality of first fire extinguishing release sub-channels can be formed in the width direction of the wrapping surface of the blanket body; and since the active fire extinguishing group includes a plurality of fire extinguishing units, each of the fire extinguishing units is adhered at intervals in the length direction of the wrapping surface of the blanket body, a plurality of second fire extinguishing release sub-channels can be formed in the length direction of the wrapping surface of the blanket body, so that a plurality of first fire extinguishing release sub-channels and a plurality of second fire extinguishing release sub-channels can be staggered and connected on the wrapping surface of the blanket body to form a fire extinguishing release flow cavity; when the multi-channel fire extinguishing wrapping blanket is wrapped on the protected object, the fire extinguishing release flow cavity is conducive to the dissipation of heat under normal conditions, effectively preventing the problem of difficult heat dissipation caused by wrapping, and at the same time, the multi-channel fire extinguishing wrapping blanket is effective in high temperature or fire. The corresponding fire extinguishing unit will absorb a large amount of heat and quickly vaporize and release the fire extinguishing factor to cover, so as to achieve a preliminary fire extinguishing and cooling effect. At the same time, the vaporized and released fire extinguishing factor can continue to vaporize and form vaporized products when the temperature is high or the flame is strong. The generated vaporized products will flow in multiple directions in the fire extinguishing release flow cavity at the same time, so that the vaporized products formed at high temperature will cause a chain vaporization and release reaction of the adjacent active fire extinguishing units when passing through the fire extinguishing release flow cavity, so as to achieve a secondary rapid fire extinguishing and cooling. In this way, compared with the traditional single-channel, the multiple active fire extinguishing units disclosed in the present invention continuously superimpose the vaporization and release reactions to achieve point-to-surface interconnection, thereby achieving a rapid fire extinguishing and cooling effect, so as to kill the temperature or flame in the initial stage, effectively reduce the spread of the flame, and greatly reduce the probability of fire.
[0021] 2. In addition, the formed fire-extinguishing release flow cavity can provide more wrapping bending points to ensure that the multi-channel fire-extinguishing wrapping blanket can better wrap and adhere to special-shaped protected objects, especially the application of wrapping objects with special-shaped structures such as pipes and cables.

DETAILED DESCRIPTION
[0031] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.
[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0035] See also Figures 1 to 3 A multi-channel fire extinguishing wrapping blanket 10 of one embodiment includes a blanket body 100, and the multi-channel fire extinguishing wrapping blanket 10 also includes a plurality of active fire extinguishing groups 200, each of the active fire extinguishing groups 200 is adhered to the width direction of the wrapping surface of the blanket body 100 at intervals, and a plurality of first fire extinguishing release sub-channels 310 are formed in the width direction of the wrapping surface of the blanket body 100; each of the active fire extinguishing groups 200 includes a plurality of fire extinguishing units 210, each of the fire extinguishing units 210 is adhered to the length direction of the wrapping surface of the blanket body 100 at intervals, and a plurality of second fire extinguishing release sub-channels 320 are formed in the length direction of the wrapping surface of the blanket body 100; each of the first fire extinguishing release sub-channels 310 is interconnected with each of the second fire extinguishing release sub-channels 320 to form a fire extinguishing release flow cavity 300.
[0036] It can be understood that since the multiple active fire extinguishing groups 200 are adhered to the width direction of the wrapped surface of the blanket body 100 at intervals, multiple first fire extinguishing release sub-channels 310 can be formed in the width direction of the wrapped surface of the blanket body 100; and since the active fire extinguishing group 200 includes multiple fire extinguishing units 210, each of the fire extinguishing units 210 is adhered to the length direction of the wrapped surface of the blanket body 100 at intervals, multiple second fire extinguishing release sub-channels 320 can be formed in the length direction of the wrapped surface of the blanket body 100, so that the multiple first fire extinguishing release sub-channels 310 and the multiple second fire extinguishing release sub-channels 320 can be staggered and connected on the wrapped surface of the blanket body 100 to form a fire extinguishing release flow cavity 300; when the multi-channel fire extinguishing wrapping blanket 10 is wrapped on a protected object, the fire extinguishing release flow cavity 300 is conducive to the dissipation of heat under normal conditions, effectively preventing the problem of difficult heat dissipation due to wrapping, and at the same time at high When the temperature is high or the flame is strong, the corresponding fire extinguishing unit 210 of the multi-channel fire extinguishing blanket 10 will absorb a large amount of heat and quickly vaporize and release the fire extinguishing factor to cover, so as to achieve a preliminary fire extinguishing and cooling effect. At the same time, the vaporized and released fire extinguishing factor can continue to vaporize and form vapor when the temperature is high or the flame is strong, and the generated vapor will flow in multiple directions in the fire extinguishing release flow cavity 300 at the same time, so that the vapor formed at high temperature will cause a chain vaporization and release reaction of the adjacent active fire extinguishing unit 210 when passing through the fire extinguishing release flow cavity 300, so as to achieve a secondary rapid fire extinguishing and cooling. In this way, compared with the traditional single-channel, the multiple active fire extinguishing units 210 of the present invention continuously superimpose the vaporization and release reaction to achieve point-to-surface interconnection, so as to achieve a rapid fire extinguishing and cooling effect, so as to kill the temperature or flame in the initial stage, effectively reduce the spread of the flame, and greatly reduce the probability of fire.
[0037] It is worth mentioning that the formed fire extinguishing release flow cavity 300 can provide more wrapping bending points to ensure that the multi-channel fire extinguishing wrapping blanket 10 can better wrap and attach to special-shaped protective objects, especially pipes, cables, lithium batteries, battery module installation lead-out wires and other special-shaped structure wrapping applications.
[0038] like Figure 2 and Figure 3 As shown, in one embodiment, a first intersection 330 is formed at the intersection of each of the second fire extinguishing release sub-channels 320 and one of the first fire extinguishing release sub-channels 310. It can be understood that the additional first intersection 330 is conducive to the collection and circulation of vaporized matter at the first intersection 330, so as to ensure that the vaporized matter in the fire extinguishing release flow cavity 300 can well cause the chain vaporization release reaction of the adjacent active fire extinguishing units 210, and effectively avoid the problem that the vaporized matter cannot achieve good circulation due to too much vaporization to affect the superimposed vaporization release reaction of multiple active fire extinguishing units 210.
[0039] like Figure 4 , Figure 5 and Figure 7 As shown, in one embodiment, each of the fire extinguishing units 210 is further formed with a third fire extinguishing release sub-channel 211, and both ends of the third fire extinguishing release sub-channel 211 are respectively connected to the adjacent first fire extinguishing release sub-channel 310 and the second fire extinguishing release sub-channel 320.
[0040] It can be understood that by adding a third fire extinguishing release sub-channel 211 to each fire extinguishing unit 210, the third fire extinguishing release sub-channel 211 can be connected with the adjacent first fire extinguishing release sub-channel 310 and the second fire extinguishing release sub-channel 320. In this way, not only the flow area of the fire extinguishing release flow cavity 300 is increased, thereby increasing more release points of perfluoroacetone, so as to ensure that the multi-channel fire extinguishing wrapping blanket 10 can quickly start the release of perfluoroacetone in the corresponding solid aerogel perfluoroacetone fire extinguishing unit 210, so as to accurately monitor the fire situation in a small space and effectively avoid the occurrence of fire; on the other hand, the added third fire extinguishing release sub-channel 211 can divide the solid aerogel perfluoroacetone fire extinguishing unit 210 into more wrapping bending points, further ensuring that the multi-channel fire extinguishing wrapping blanket 10 can better wrap the wrapping attached to the special-shaped structure, so as to achieve better protection and fire extinguishing performance.
[0041] like Figures 4 to 6As shown, in one embodiment, each of the fire extinguishing units 210 is also formed with a fourth fire extinguishing release sub-channel 212, and the fourth fire extinguishing release sub-channel 212 is staggeredly connected with the third fire extinguishing release sub-channel 211 to form a second intersection 213, and the two ends of the fourth fire extinguishing release sub-channel 212 are respectively connected with the adjacent first fire extinguishing release sub-channel 310 and the second fire extinguishing release sub-channel 320.
[0042] It can be understood that since the added fourth fire extinguishing release sub-channel 212 can be interconnected with the third fire extinguishing release sub-channel 211 to form a second intersection 213, the fluidity of the vapor in the middle of the fire extinguishing unit 210 is increased, and the two ends of the fourth fire extinguishing release sub-channel 212 are respectively connected to the first fire extinguishing release sub-channel 310 and the second fire extinguishing release sub-channel 320. In this way, not only can more release points of perfluorohexanone be provided for the multi-channel fire extinguishing blanket 10, but also the fluidity of the vapor in the fire extinguishing release flow cavity 300 is further improved, ensuring that the multi-channel fire extinguishing blanket 10 can achieve a faster fire extinguishing and cooling effect.
[0043] like Figures 1 to 3 As shown, in one embodiment, the shape of each fire extinguishing unit 210 is one or both of a polygon and a circle, so as to ensure that each fire extinguishing unit 210 can form a staggered and interconnected fire extinguishing release flow cavity 300 on the wrapped surface of the blanket body 100 .
[0044] like Figure 1 , Figure 2 and Figure 7 As shown, in some of the embodiments, the fire extinguishing unit 210 is one or two of a parallelogram, a rectangle, a square and a triangle.
[0045] It can be understood that, since a polygon can save more materials than a circle, a polygonal fire extinguishing unit 210 will be the preferred shape. For example, in some embodiments, the fire extinguishing unit 210 may be a parallelogram; in some other embodiments, the fire extinguishing unit 210 may also be a rectangle, a square, or a triangle; in another example, the fire extinguishing unit 210 may be a combination of a parallelogram and a triangle, a combination of a triangle and a square, or a combination of a rectangle and a triangle. Therefore, those skilled in the art may make a selection based on the actual protected object, and no specific limitation is made in the present disclosure.
[0046] like Figure 5 As shown, in a preferred embodiment, the fire extinguishing unit 210 is a square, and a third fire extinguishing release sub-channel 211 and a fourth fire extinguishing release sub-channel 212 are respectively formed in the square, and the third fire extinguishing release sub-channel 211 and the fourth fire extinguishing release sub-channel 212 divide the fire extinguishing unit 210 into four right-angled isosceles triangles.
[0047] like Figure 7 As shown, in a more preferred embodiment, the fire extinguishing unit 210 is a regular parallelogram, and a third fire extinguishing release sub-channel 211 is formed in the regular parallelogram, and the third fire extinguishing release sub-channel 211 divides the fire extinguishing unit 210 into two equilateral triangles.
[0048] In one embodiment, each of the fire extinguishing units 210 is a solid aerogel perfluorohexanone fire extinguishing sheet. It can be understood that since the solid aerogel perfluorohexanone fire extinguishing sheet has high strength, when it is used in conjunction with the flexible blanket body 100, it is not necessary to add additional reinforcements such as fibers to achieve a highly flexible and high-strength multi-channel fire extinguishing wrapping blanket 10, so as to well ensure that the multi-channel fire extinguishing wrapping blanket 10 can still maintain a good wrapping structure shape after long-term use, and effectively avoid the problem that the traditional wrapping blanket is easy to collapse during use. It is worth mentioning that although the solid aerogel perfluorohexanone fire extinguishing sheet has high strength, it is impossible to achieve a good wrapping of some special-shaped protected objects. Therefore, by making the solid aerogel perfluorohexanone fire extinguishing sheet into a plurality of small-area fire extinguishing units 210, especially in conjunction with the use of the blanket body 100, the fire extinguishing release flow cavity 300 can provide more wrapping bending points to achieve the wrapping of special-shaped protected objects, further broadening the application field of the solid aerogel perfluorohexanone fire extinguishing sheet.
[0049] In one embodiment, the solid aerogel perfluorohexanone fire extinguishing sheet is provided by Guangdong Heiwei Fire Protection Technology Co., Ltd., and the solid aerogel perfluorohexanone fire extinguishing sheet can be realized by existing technology, so it is not described in detail in this disclosure.
[0050] like Figure 5 and Figure 6 As shown, in one embodiment, a preset gap 120 is formed between the surrounding edges of the covering surface 110 of the blanket body 100 and each of the active fire extinguishing groups 200. It can be understood that since the preset gap 120 is formed between the surrounding edges of the covering surface 110 of the blanket body 100 and each of the active fire extinguishing groups 200, and the preset gap 120 is connected to the fire extinguishing release flow cavity 300, on the one hand, the vapor in the fire extinguishing release flow cavity 300 can be better diffused to the surroundings, thereby improving the circulation of the vapor in the fire extinguishing release flow cavity 300, so as to ensure that the vapor can well cause the chain vaporization release reaction of the active fire extinguishing unit 210 when circulating, so as to achieve secondary rapid fire extinguishing and cooling; on the other hand, it is conducive to the diffusion of heat or vapor in the fire extinguishing release flow cavity 300 to the outside, effectively avoiding the phenomenon of cracking caused by excessive vapor or heat in the fire extinguishing release flow cavity 300.
[0051] In one embodiment, the blanket body 100 is one of aramid blanket, high silica fiberglass blanket or aluminum foil composite fiberglass blanket. It can be understood that since aramid blanket, high silica fiberglass blanket and aluminum foil composite fiberglass blanket have good high flexibility. Therefore, aramid blanket, high silica fiberglass blanket and aluminum foil composite fiberglass blanket can provide a good wrapping carrier for multiple active fire extinguishing groups 200, especially with the use of small unit solid aerogel perfluorohexanone fire extinguishing tablets, to achieve the wrapping of special-shaped protective objects, further broadening the application field of solid aerogel perfluorohexanone fire extinguishing tablets.
[0052] In one embodiment, an adhesive layer is formed between each of the fire extinguishing units 210 and the wrapped surface of the blanket body 100, and the adhesive layer is an epoxy adhesive layer, so as to achieve the adhesion setting of multiple fire extinguishing units 210 and the wrapped surface of the blanket body 100. Furthermore, since the epoxy adhesive layer contains a large number of epoxy groups, it can achieve a strong adhesion with the aramid blanket, the high-silica glass fiber blanket and the aluminum foil composite glass fiber blanket, which better ensures that the multiple fire extinguishing units 210 are not easy to fall off in the strong superimposed vaporization release reaction.
[0053] The present disclosure also provides a fire extinguishing device, including the multi-channel fire extinguishing wrap blanket 10 described in any of the above embodiments. It can be understood that the fire extinguishing device also includes a fastening kit, which is arranged on the outer peripheral wall of the multi-channel fire extinguishing wrap blanket 10, so that the fastening kit can wrap and fix the multi-channel fire extinguishing wrap blanket 10 on the outer peripheral wall of the protected object, so as to achieve the wrapping and fixing of the multi-channel fire extinguishing wrap blanket 10. In this way, under normal conditions, the multi-channel fire extinguishing wrap blanket 10 can not only play a certain protective role on the protected object, but also facilitate the dissipation of heat in the multi-channel fire extinguishing wrap blanket 10, effectively preventing the problem of difficult heat dissipation due to wrapping; at the same time, at high temperature or fire, the multi-channel fire extinguishing The corresponding fire extinguishing unit 210 of the fire blanket 10 will absorb a large amount of heat to quickly vaporize and release the fire extinguishing factor for coverage. At the same time, the vaporized fire extinguishing factor can continue to vaporize and form vapor when the temperature is high or the flame is strong. The generated vapor will flow in multiple directions in the fire extinguishing release flow cavity 300 at the same time, so as to realize the continuous superposition of vaporization release reactions of multiple active fire extinguishing units 210, realize point-to-surface interconnection, and achieve secondary rapid fire extinguishing and cooling, so as to kill the temperature or flame in the initial stage, and effectively reduce the probability of fire.
[0054] In one embodiment, the fastening kit can be one or more of a fastening tie rope, a buckle, and Velcro to wrap and fix the multi-channel fire extinguishing wrap blanket 10.
[0055] Compared with the prior art, the present invention has at least the following advantages:
[0056] 1. Since a plurality of active fire extinguishing groups 200 are adhered to the width direction of the wrapping surface of the blanket body 100 at intervals, a plurality of first fire extinguishing release sub-channels 310 can be formed in the width direction of the wrapping surface of the blanket body 100; and since the active fire extinguishing group 200 includes a plurality of fire extinguishing units 210, each of the fire extinguishing units 210 is adhered to the length direction of the wrapping surface of the blanket body 100 at intervals, a plurality of second fire extinguishing release sub-channels 320 can be formed in the length direction of the wrapping surface of the blanket body 100, so that a plurality of first fire extinguishing release sub-channels 310 and a plurality of second fire extinguishing release sub-channels 320 can be staggered and connected on the wrapping surface of the blanket body 100 to form a fire extinguishing release flow cavity 300; when the multi-channel fire extinguishing wrapping blanket 10 is wrapped on a protected object, the fire extinguishing release flow cavity 300 is conducive to the dissipation of heat under normal conditions, effectively preventing the problem of difficult heat dissipation caused by wrapping, and at high temperatures Or when a fire occurs, the corresponding fire extinguishing unit 210 of the multi-channel fire extinguishing blanket 10 will absorb a large amount of heat and quickly vaporize and release the fire extinguishing factor to cover, thereby achieving a preliminary fire extinguishing and cooling effect. At the same time, the vaporized and released fire extinguishing factor can continue to vaporize and form vaporized products when the temperature is high or the flame is strong, and the generated vaporized products will flow in multiple directions in the fire extinguishing release flow cavity 300 at the same time, so that the vaporized products formed at high temperature will cause a chain vaporization and release reaction of the adjacent active fire extinguishing units 210 when passing through the fire extinguishing release flow cavity 300, so as to achieve secondary rapid fire extinguishing and cooling. In this way, compared with the traditional single-channel, the multiple active fire extinguishing units 210 of the present invention continuously superimpose the vaporization and release reactions to achieve point-to-surface interconnection, thereby achieving a rapid fire extinguishing and cooling effect, so as to kill the temperature or flame in the initial stage, effectively reduce the spread of the flame, and greatly reduce the probability of fire.
[0057] 2. In addition, the formed fire extinguishing release flow cavity 300 can provide more wrapping bending points to ensure that the multi-channel fire extinguishing wrapping blanket 10 can better wrap the wrapped objects attached to the special-shaped structures, especially the application of the wrapped objects with special-shaped structures such as pipes and cables.
[0058] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
