Description

Technical Field

[0001] This utility model relates to the field of flame quenching and fire arrestor in civil aviation safety protection equipment, and in particular to a flame quenching combined channel body device. 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 thermal runaway fire involving 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 within these bags or boxes, the flames can spread erratically. If not extinguished promptly, this can intensify the fire or create greater risks. For example, protective bags are usually not completely sealed (sealing would increase the pressure inside the bag, increasing the risk of explosion), and have several pressure relief vents. Currently, these protective bags lack dedicated flame extinguishing devices on the pressure relief vents and the inside of the bag. This prevents timely and effective extinguishing of the flames, allowing them to spread erratically within the bag. The flames may even converge and intensify, or spread to other scattered fragments of lithium-ion battery-containing electronic devices, making fire suppression more difficult and potentially releasing the flames into external areas through the pressure relief vents. Utility Model Content

[0003] The purpose of this utility model is to provide a flame quenching combined channel body device, which is mainly used on the inside of civil aviation fireproof protective bags or protective boxes and at the pressure relief port, to quench nearby flames in a timely and effective manner, prevent flames from spreading and scattering, and enhance fire extinguishing efficiency and intensity.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A flame quenching combined channel body device includes a flame quenching extension layer, which is composed of a surface layer A, a surface layer B, and a flame guiding channel body connecting the surface layer A and the surface layer B.

The flame quenching extension layer is spirally rolled from the inside to the outside to form a quenching structure unit, and several quenching structure units are sequentially overlapped and connected to form a flame quenching combined channel body device.

[0006] To better realize this utility model, the quenching structure unit is formed by rolling the flame quenching extension layer tightly from the inside to the outside, and the quenching structure unit forms a quenching structure layer from the inside to the outside.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the embodiments:

[0028] Example

[0029] like Figure 1 As shown, a flame-quenching combined channel body device includes a flame-quenching extension layer 1, which consists of a surface layer A2, a surface layer B3, and a flame-guiding channel body 4 (such as...) connecting the surface layer A2 and the surface layer B3. Figure 1As shown, the flame guiding channel body 4 is a polygonal panel along its length. The flame guiding channel body 4 divides the space between surface layer A2 and surface layer B3 into wavy or triangular polygonal flame quenching channels. (See [reference]). Figure 1 , Figure 1 This is a schematic diagram of the side or cross-section of the flame quenching extension layer 1. Between surface layer A2 and surface layer B3 is a flame guiding channel 4, which is zigzag-shaped and divides the space between surface layer A2 and surface layer B3. The flame quenching extension layer 1 is spirally rolled from the inside out to form quenching structural units 5. Several quenching structural units 5 are sequentially overlapped and connected to form a flame quenching combined channel device. In some embodiments, the quenching structural unit 5 is formed by sequentially and tightly rolling the flame quenching extension layer 1 from the inside out, forming a quenching structural layer 51 from the inside out. The end face of the quenching structural unit 5 is the cross-sectional side of the flame quenching extension layer 1 after rolling and the flame quenching channel assembly. See also... Figure 2 In this embodiment, the quenching structure unit 5 can be made by concentrically rolling the flame-quenching extension layer 1, that is, rolling several concentric circles and tightly fitting them together from the inside to the outside. If the flame-quenching combined channel device of this utility model is installed at the pressure relief port of the protective bag, the flame guiding channel 4 between the flame-quenching extension layers 1 serves the purpose of flame quenching, and also serves to relieve pressure (the following technical description states that the adjacent quenching structure units 5 are staggered to better block flame quenching, and do not affect the pressure relief function); if the flame-quenching combined channel device is installed inside the protective bag, its main purpose is to achieve flame quenching.

[0030] like Figure 3 As shown, the flame quenching combined channel body device of this utility model consists of quenching structure units 5 connected in sequence with their end faces overlapping. The flame quenching channels on the end faces of adjacent quenching structure units 5 in the flame quenching combined channel body device are staggered. It is preferred to adopt staggered positioning, that is, the flame guiding channels 4 of adjacent quenching structure units 5 are staggered and do not communicate with each other; of course, it is also possible not to be staggered.

[0031] In some embodiments, the first and last quenching structural units 5 in the flame quenching combined channel body device are equipped with end-side connectors 6 on their end faces, and end-side connectors 6 are installed between adjacent quenching structural units 5 in the middle of the flame quenching combined channel body device. The flame quenching combined channel body device is connected and fixed in the length direction by a plurality of limiting connecting rods 7. Figure 5 , Figure 6As shown, the end-side connector 6 includes an annular edge body 63 and several end-side reinforcing beams 62 connected to the annular edge body 63. A gap space is formed between adjacent end-side reinforcing beams 62 in the end-side connector 6, and all gap spaces of the end-side connector 6 are combined to form an end-side gap space 61. Several end-side connection positions 631 are distributed on the annular edge body 63 of the end-side connector 6. All end-side connection positions 631 of the end-side connector 6 in the flame quenching combined channel body device correspond in the length direction and are connected and fixed in series by limiting connecting rods 7. Preferably, all limiting connecting rods 7 form a limiting cylindrical cage, and the quenching structure unit 5 of the flame quenching combined channel body device is located inside the limiting cylindrical cage. More preferably, as... Figure 5 As shown, the quenching structure unit 5 of the flame quenching combined channel body device is also covered with a connecting shaping panel 8 (the connecting shaping panel 8 can be covered separately, or the connecting shaping panel 8 can be located inside all the limiting connecting rods 7, first shaped and connected into a whole, and then reinforced by all the limiting connecting rods 7).

[0032] In some preferred embodiments, the quenching structural monomer 5 is cylindrical or cuboid in shape, such as... Figure 3 , Figure 5 As shown, the quenching structure unit 5 is cylindrical in shape. Similarly, the flame quenching combined channel device formed by overlapping individual quenching structure units 5 is also cylindrical. The surface layer A2 and / or surface layer B3 of the flame quenching extension layer 1 is a non-perforated panel or a perforated mesh structure. (See attached image.) Figure 4 The surface layer A2 and / or surface layer B3 of the flame-quenched extension layer 1 is a perforated mesh panel.

[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.
