Description

Technical Field

[0001] The present invention relates to the field of flame quenching and fire arresting in civil aviation safety protection equipment, and in particular to a flame quenching combined channel body device. Background Art

[0002] With the widespread use of lithium batteries in electronic devices, fires and explosions caused by thermal runaway in aircraft cabins have become frequent. If a lithium battery or electronic device containing a lithium battery catches fire due to thermal runaway, a protective bag or box is typically used to isolate and extinguish the fire. When a lithium battery or electronic device containing a lithium battery burns in a protective bag or box, the flames can spread wildly inside. If not promptly extinguished, the flames can spread and increase the risk of fire. For example, protective bags are typically not sealed (sealing increases the air pressure in the bag, increasing the risk of explosion) and have several pressure relief vents. Existing protective bags lack dedicated flame quenching devices on the pressure relief vents and inside the bags. This prevents flames from being effectively extinguished in a timely manner, allowing them to spread wildly within the bag, potentially converging to intensify the fire or scattering to other scattered fragments of electronic devices containing lithium batteries, making them easily ignited. This makes fire extinguishing more difficult and can even be released through the pressure relief vents to the outside, causing harm. Summary of the Invention

[0003] The purpose of the present invention is to provide a flame quenching combined channel body device, which is mainly used in the inside of civil aviation fire protection bags or protection boxes and pressure relief ports to promptly and effectively quench nearby flames, prevent the flames from spreading and increasing the efficiency and intensity of fire extinguishing.

DETAILED DESCRIPTION

[0019] Below in conjunction with embodiment, the present invention is described in further detail: Example

[0020] like Figure 1 As shown, a flame quenching combined channel body device includes a flame quenching extension layer 1, the flame quenching extension layer 1 is composed of a surface layer A2, a surface layer B3 and a flame guide channel body 4 connected between the surface layer A2 and the surface layer B3 (such as Figure 1 As shown, the flame guide channel body 4 is composed of a folded panel along the length direction. The flame guide channel body 4 divides the space between the surface layer A2 and the surface layer B3 into a wavy or triangular folded flame quenching channel, see Figure 1 , Figure 1It is a side or cross-sectional diagram of the flame quenching extension layer 1. Between the surface layer A2 and the surface layer B3 is the flame guiding channel body 4. The flame guiding channel body 4 is in a broken line shape and divides the space between the surface layer A2 and the surface layer B3 into a broken line. The flame quenching extension layer 1 is spirally rolled from the inside to the outside to form a quenching structure monomer 5. Several quenching structure monomers 5 are overlapped and connected in sequence to form a flame quenching combined channel body device. In some embodiments, the quenching structure monomer 5 is formed by the flame quenching extension layer 1 being rolled tightly from the inside to the outside. The quenching structure monomer 5 forms a quenching structure layer 51 from the inside to the outside. The end face of the quenching structure monomer 5 is the cross-sectional side after the flame quenching extension layer 1 is rolled and the flame quenching channel is combined. See Figure 2 In this embodiment, the quenching structure unit 5 can be concentrically rolled with the flame quenching extension layer 1, that is, several concentric circles are rolled and tightly fitted sequentially from the inside out. If the flame quenching combined channel body device of the present invention is installed at the pressure relief port of the protective bag, the flame guiding channel body 4 between the flame quenching extension layers 1 serves the purpose of flame quenching and also provides pressure relief or pressure reduction. (The following technical description describes the offset of adjacent quenching structure units 5 only for better flame barrier quenching and does not affect the pressure relief or pressure reduction function.) If the flame quenching combined channel body device is installed inside the protective bag, its primary purpose is flame quenching.

[0021] like Figure 3 As shown, the flame quenching combined channel body device of the present invention is composed of quenching structural monomers 5 connected in sequence by overlapping end faces. The flame quenching channels of the end faces of adjacent quenching structural monomers 5 in the flame quenching combined channel body device are staggered with each other. Preferably, staggering is adopted, that is, the flame guiding channel bodies 4 of adjacent quenching structural monomers 5 are staggered and not connected to each other; of course, non-staggering is also possible.

[0022] In some embodiments, the first and last quenching structure monomers 5 in the flame quenching combined channel body device are installed with end side connectors 6, and the adjacent quenching structure monomers 5 in the middle of the flame quenching combined channel body device are installed with end side connectors 6. The flame quenching combined channel body device is connected and fixed in the length direction by a plurality of limit connecting rods 7. Figure 5 、 Figure 6As shown, the end side connector 6 includes an annular edge body 63 and a plurality of end side reinforcement beams 62 connected to the annular edge body 63. A gap space is formed between adjacent end side reinforcement beams 62 in the end side connector 6, and all the gap spaces of the end side connector 6 are collectively formed into an end side gap space 61. The annular edge body 63 of the end side connector 6 is distributed with a plurality of end side connection positions 631. The end side connection positions 631 of all the end side connectors 6 in the flame quenching combined channel body device correspond in the length direction and are connected and fixed in series by the limiting connection rods 7. Preferably, all the limiting connection rods 7 form a limiting cylindrical cage, and the quenching structure monomer 5 of the flame quenching combined channel body device is located inside the limiting cylindrical cage. Further preferably, as Figure 5 As shown, the exterior of the quenching structure unit 5 of the flame quenching combined channel body device is also covered with a connecting shaping panel 8 (it can be covered with a connecting shaping panel 8 alone, or the connecting shaping panel 8 is located on the inner side of all the limiting connecting rods 7, and is first shaped and connected into a whole, and then reinforced through all the limiting connecting rods 7).

[0023] In some preferred embodiments, the quenching structure monomer 5 is cylindrical or rectangular as a whole, such as Figure 3 、 Figure 5 As shown, the quenching structure monomer 5 is cylindrical in shape as a whole. If the flame quenching combined channel device formed by overlapping the quenching structure monomers 5 is also cylindrical in shape as a whole. The surface layer A2 and / or the surface layer B3 of the flame quenching extension layer 1 are non-hollow panels or hollow mesh structures, see Figure 4 The surface layer A2 and / or the surface layer B3 of the flame quenching extension layer 1 are hollow mesh panels.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
