The honeycomb quenching body is composed of multiple honeycomb unit layers from the inside out, each honeycomb unit layer being made of a layered structure. The layered structure includes a first facet and a second facet, with an intermediate honeycomb structure connecting the first and second facets. The honeycomb quenching body of this utility model, composed of multiple honeycomb unit layers from the inside out, with an intermediate honeycomb structure between the first and second facets of the honeycomb unit layers, forms a honeycomb-shaped flame quenching channel on the end face and inside of the honeycomb quenching body. The entire flame near the inside of the protective equipment is dispersed and segmented by the honeycomb-shaped flame quenching channel. As the dispersed and segmented small flames enter the honeycomb-shaped flame quenching channel, they are rapidly quenched. The honeycomb-shaped flame quenching channel is mainly used inside protective bags or boxes and at pressure relief vents, enabling timely and effective quenching of nearby flames.

Description

Technical Field

[0001] This utility model relates to the field of civil aviation fire extinguishing and protection technology, and in particular to a honeycomb-shaped flame quenching channel. Background Technology

[0002] With the widespread use of lithium batteries in electronic devices, fires and explosions caused by thermal runaway in aircraft cabins are frequent. In the event of a fire caused by thermal runaway of a lithium battery or lithium-ion battery-containing electronic device, protective bags or boxes are typically used for isolation and fire suppression. However, when the lithium battery or lithium-ion battery-containing electronic device burns inside the protective bag or box, the flames can spread erratically. If not extinguished promptly, this can increase the fire's intensity or pose a greater risk. For example, protective bags are usually not sealed (sealing would increase the pressure inside the bag, increasing the risk of explosion), and have several pressure relief vents. Existing protective bags lack dedicated flame extinguishing devices on the pressure relief vents and the inside of the bag. This prevents the flames inside the bag from being effectively extinguished in a timely manner, causing them to spread erratically within the bag, increasing the difficulty of fire suppression, and potentially even releasing them through the pressure relief vents to the outside area, causing harm.

[0026] Example

[0027] like Figure 1 As shown, a honeycomb-shaped flame quenching channel body includes a layered structure 3 and a honeycomb quenching body 1. The honeycomb quenching body 1 is composed of multiple honeycomb unit layers 2 from the inside out, and each honeycomb unit layer 2 is made of the layered structure 3. The layered structure 3 includes a first facet 31 and a second facet 32, and an intermediate honeycomb body 33 is provided between the first facet 31 and the second facet 32 ​​of the layered structure 3. The intermediate honeycomb body 33 is preferably a corrugated panel, which divides the space between the first facet 31 and the second facet 32 ​​of the layered structure 3 into upper and lower corrugated channels. Preferably, the intermediate honeycomb body 33 can also be a honeycomb mesh structure. Since the honeycomb quenching body 1 is composed of multiple honeycomb unit layers 2 from the inside out, see [reference needed]. Figure 1 The honeycomb quenching body 1 forms honeycomb-shaped flame quenching channels on its end face. The surrounding flame is dispersed and divided by these channels, and the dispersed, divided small flames are rapidly quenched after entering the honeycomb-shaped flame quenching channels. In some embodiments, the first facet 31 and / or the second facet 32 ​​of the layered structure 3 is a non-perforated panel or a perforated mesh structure, see [reference needed]. Figure 4 The first facet 31 adopts a perforated mesh structure (of course, a non-perforated panel can also be used directly). Preferably, the honeycomb quenching body 1 is cylindrical or cuboid in shape, see [reference]. Figure 3The honeycomb structure 33 in the middle is preferably a wavy panel, but it can also be other shapes, such as a zigzag shape.

[0028] The first preferred structural variation of the honeycomb quenching body 1 of this utility model is as follows: the honeycomb quenching body 1 is formed by spirally rolling a layered structure 3 into several layers of honeycomb unit layers 2. The honeycomb quenching body 1 is formed by spirally rolling a layered structure 3 into several spiral layers of honeycomb unit layers 2.

[0029] The second preferred structural solution of the honeycomb quenching body 1 of this utility model is as follows: Figure 1 , Figure 2 As shown, each honeycomb unit layer 2 of the honeycomb quenching body 1 is a concentric circle layer, and each honeycomb unit layer 2 is composed of a layer structure 3. The honeycomb quenching body 1 is made up of multiple concentric honeycomb unit layers 2 tightly fitted together from the inside to the outside. Preferably, the inner layer of the honeycomb quenching body 1 has a central connecting hole along the length direction. The central connecting hole facilitates the insertion and mating with the central cylinder 7. The central cylinder 7 can be shaped and can also serve as a through-hole connection (in use, it can be stably connected to the protective box or protective bag through the central cylinder 7).

[0030] In some preferred embodiments, such as Figure 5 As shown, this utility model also includes a first connecting end side member 4 and a second connecting end side member 5. The first connecting end side member 4 is connected to one end side of the honeycomb quenching body 1, and the second connecting end side member 5 is connected to the other end side of the honeycomb quenching body 1. The first connecting end side member 4 has a hollowed-out end side channel space 41. Depending on the actual use, if the honeycomb flame quenching channel body is used inside the protective bag, its second connecting end side member 5 may not have a hollowed-out end side channel space 41. In this case, the honeycomb flame quenching channel body plays a quenching role. If the honeycomb flame quenching channel body is installed at the pressure relief port of the protective bag, the second connecting end side member 5 also has a hollowed-out end side channel space 41. The end side channel space 41 of the first connecting end side member 4, the end side channel space of the second connecting end side member 5, and the honeycomb quenching channel inside the honeycomb quenching body 1 are connected to form a pressure relief channel.

[0031] In some preferred embodiments, the first connecting end member 4 includes an annular edge structure 42 and a plurality of end-side structural reinforcement beams 6 connected to the center of the annular edge structure 42. All end-side structural reinforcement beams 6 are connected and fixed, and all end-side structural reinforcement beams 6 form a hollow portion as an end-side channel space 41. Preferably, all end-side structural reinforcement beams 6 of the first connecting end member 4 are connected at the center of the end face of the first connecting end member 4. The second connecting end member 5 has the same structure as the first connecting end member 4. A central cylinder 7 corresponding to the central connecting hole is connected between the center of the end face of the first connecting end member 4 and the center of the end face of the second connecting end member 5. The central cylinder 7 plays a structural reinforcement role at the center of the honeycomb quenching body 1 and is connected and installed to the protective bag or protective box through the first connecting end member 4 or the second connecting end member 5.

[0032] See Figure 5 The first connecting end side member 4 has three end side structural reinforcement beams 6, which are evenly distributed on the surface of the first connecting end side member 4 with the center of the end face of the first connecting end side member 4 as the center; if the honeycomb flame quenching channel is installed at the pressure relief port of the protective bag, the second connecting end side member 5 is also provided with the same end side structural reinforcement beams 6.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
