Description

Technical Field

[0001] This invention relates to the field of emergency response technology, and in particular to an aviation emergency lithium battery fireproof bag assembly with rapid deployment function. Background Technology

[0002] Currently, lithium-ion batteries are the primary energy storage and power supply system for everyday electronic devices, with widespread applications including mobile phones, tablets, laptops, power banks, and other readily accessible electronic products. However, lithium-ion batteries contain a large amount of toxic, harmful, and flammable substances, posing certain safety hazards. In the event of a fire or explosion, if not handled promptly and correctly, it could pose unpredictable dangers to surrounding people and the environment. Furthermore, a rapid emergency response after a lithium battery experiences thermal runaway can significantly reduce the likelihood of such accidents.

[0003] Aircraft cabin safety is always a major concern, as the losses caused by fires or explosions in the confined space of a cabin during takeoff are incalculable. With the widespread use of electronic products, lithium batteries or devices containing lithium batteries are unavoidable on aircraft. Due to the inherent dangers of lithium batteries, the likelihood of aircraft safety accidents is significantly increased. Existing emergency response kits and bags for lithium battery fires in the cabin lack specialized toxic gas filtration devices and cannot meet the requirements for rapid emergency response. To prevent safety accidents caused by lithium battery fires or explosions on aircraft, it is necessary to equip the aircraft with dedicated, rapidly responding, fire-resistant, and flame-retardant emergency equipment.

[0004] CN202557965U discloses a lithium battery explosion-proof and fireproof bag, comprising a fiber cloth forming a bag body for housing the lithium battery. The fiber cloth includes an inner layer and an outer layer. The inner layer is a fire-resistant and explosion-proof composite fiber cloth, which is either a soft copper foil fiberglass cloth with a copper foil layer as the base layer or a soft aluminum foil fiberglass cloth with an aluminum foil layer as the base layer. The outer layer is a polyvinyl chloride (PVC) mesh fiber cloth. This lithium battery explosion-proof and fireproof bag is mainly designed as a fire-resistant and explosion-proof container for housing lithium batteries. Its design focuses on providing physical isolation and basic fire and explosion protection, but it cannot achieve rapid fire extinguishing and cooling, nor can it facilitate rapid fire extinguishing operations by users. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an aviation emergency lithium battery fireproof bag assembly with rapid deployment function, which meets the needs of use in the confined space of the aircraft cabin, forming a complete emergency treatment assembly.

Detailed Implementation

[0041] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0042] Example 1

[0043] like Figures 1 to 6 As shown: An aviation emergency lithium battery fireproof bag assembly with rapid deployment function. The fireproof bag includes two first self-supporting rods 1 and two second self-supporting rods 2. The first self-supporting rods 1 and the second self-supporting rods 2 are both approximately triangular in shape and form a closed loop structure. The first self-supporting rods 1 and the second self-supporting rods 2 are arranged opposite each other. The first self-supporting rods 1 and the second self-supporting rods 2 are covered with flexible fireproof cloth 3 around their sides and bottoms. The first self-supporting rods 1 and the second self-supporting rods 2 are supported by the flexible fireproof cloth 3. The flexible fireproof cloth 3 on the outside of the two second self-supporting rods 2 is respectively provided with an opening 4 and a water inlet 5. A zipper 6 is provided at the opening 4. The burning lithium battery electronic products are put into the bag through the opening 4 and sealed by the zipper 6. The water inlet 5 is provided with a plug-type active fire extinguishing unit 7. The top area of ​​the first self-supporting rods 1 and the second self-supporting rods 2 is equipped with a smoke filter 8. Zipper 6 is a fire-resistant zipper, and the zipper tape is made of permanent fire-resistant fibers such as DuPont sand thread. Specifically, it is either an adhesive fire-resistant zipper or a coated fire-resistant zipper.

[0044] The first self-supporting rod 1 and the second self-supporting rod 2 are made of high-temperature resistant elastic steel wire, such as ASTM A228 piano wire or 50CrV spring steel wire. The first self-supporting rod 1 and the second self-supporting rod 2 can be bent when an external force is applied, and the first self-supporting rod 1 and the second self-supporting rod 2 can immediately return to their original shape after the external force is removed. The elastic steel wire can withstand high temperatures up to 1000℃.

[0045] The flexible fireproof cloth 3 is made of three layers. The inner layer of the flexible fireproof cloth 3 is a fire-retardant fiber layer 9 with a fire-retardant coating. The middle layer of the flexible fireproof cloth 3 is a heat-insulating cotton layer 10. The outer layer of the flexible fireproof cloth 3 is a waterproof and wear-resistant flexible material woven layer 11. The three-layer structure can effectively reduce the combustion hazards of lithium battery products, isolate the burning battery and reduce the temperature of the external environment, and reduce the harm to personnel caused by sparks and smoke during the fire.

[0046] The inner layer material 9 is selected from one of Nomex fiber, aramid fiber, and basalt fiber, and the thickness of the inner layer material 9 is 2-4 mm. The fire-retardant coating on the inner layer material 9 is selected from one of silicate material and intumescent flame retardant.

[0047] The material of the intermediate layer 10 is selected from glass fiber, aluminum silicate fiber, and ceramic fiber, and the thickness of the intermediate layer material 10 is 2 to 5 mm.

[0048] The outer layer material 11 is selected from polyethylene fiber, polypropylene fiber, and carbon fiber, and the thickness of the outer layer material 11 is 2 to 4 mm.

[0049] Flexible fireproof fabric 3 is sewn onto the outer surfaces of the first self-supporting rod 1 and the second self-supporting rod 2. The first self-supporting rod 1 and the second self-supporting rod 2 support each other through the flexible fireproof fabric 3. In use, the first self-supporting rod 1 and the second self-supporting rod 2 can be quickly deployed for support. The rapid deployment function of the fireproof bag meets the requirements of emergency response in the first instance after a fire occurs, and takes into account the rapid emergency handling of fire accidents.

[0050] Zipper 6 is a high-temperature resistant metal zipper, which can withstand temperatures up to 500°C.

[0051] The water inlet 5 is equipped with a plug-type active fire extinguishing unit 7. The water inlet 5 can quickly introduce water, which can quickly extinguish and cool down the burning lithium battery inside the bag, reduce the risk of battery heat spread, and control the intensity of battery combustion. The plug-type active fire extinguishing unit 7 can prevent smoke from being emitted from the water inlet 5, and allow the smoke to be emitted through the smoke filter device 8 installed on the top, reducing the harm of toxic and harmful smoke to personnel.

[0052] The flue gas filtration device 8 includes a flexible double-layer porous cloth 12 and a filter material interlayer 13. The toxic and harmful fumes released by the burning lithium battery are adsorbed by the filter material interlayer 12 in the filtration device 8, reducing the possibility of personnel inhaling toxic and harmful substances in a confined environment. The filter material interlayer 12 can use existing flue gas filter materials.

[0053] The plug-type active fire suppression unit 7 has a plug-like structure, see [link / reference]. Figure 7The plug-type active fire suppression unit includes a plug body 7-11, a carbon dioxide storage chamber 7-12 located in the plug body 7-11, an infrared temperature sensor 7-13 located at the inner end of the plug body 7-11, a miniature water pump 7-14 located in the plug body 7-11, a hose 7-15 connected to the inlet end of the miniature water pump 7-14, and a nozzle 7-16 located at the inner end of the plug body 7-11. The hose 7-15 can extend from the inner end of the plug body 7-11 and is used to draw water from an external container. The outlet end of the miniature water pump 7-14 is connected to the nozzle 7-16 and is used to pump water into the bag. The carbon dioxide storage chamber 7-12 stores liquid carbon dioxide, and the output end of the carbon dioxide storage chamber 7-12 is located at the inner end of the plug body 7-11. The plug-type active fire extinguishing unit also includes a controller 7-17, a first solenoid valve 7-18 located at the outlet end of the carbon dioxide storage chamber 7-12, a second solenoid valve 7-19 located at the outlet end of the micro water pump 7-14, and a water pump start button 7-20 located at the outer end of the plug body 7-11.

[0054] The controller 7-17 is communicatively connected to the first solenoid valve 7-18, the micro water pump 7-14, the second solenoid valve 7-19, the infrared temperature sensor 7-13, and the water pump start button 7-20, respectively; the controller is a microcontroller or a processor with an x86 architecture, ARM architecture, or RISC-V architecture.

[0055] The sealing body 7-11 has a hose receiving cavity 7-21, and the hose 7-15 can be retracted into or drawn out of the hose receiving cavity 7-21. After the hose 7-15 is drawn out, its end can be placed in a mineral water bottle to extract water from the bottle and pump it into the bag.

[0056] The infrared temperature sensor 7-13 inside the sealing body 7-11 activates to detect the ambient temperature and determine whether the fire extinguishing procedure needs to be initiated. When the detected ambient temperature exceeds a preset threshold, the controller 7-17 activates the first solenoid valve 7-18, opening the output end of the carbon dioxide storage chamber 7-12 to release liquid carbon dioxide. Simultaneously, the user can activate the fire extinguishing unit by pressing the water pump start button 7-20 on the outside of the sealing body 7-11. At the same time, the second solenoid valve 7-19 at the outlet of the micro water pump 7-14 opens, drawing water from the bottle and pumping it into the bag. A small amount of water is sufficient to cool the small lithium battery. All electrical devices within the sealing body 7-11 can be powered by internally embedded button batteries.

[0057] The quick-deployment emergency fireproof bag provided by this invention is compact, portable, easy to store, space-saving, and simple to operate. It can be quickly deployed and used in crowded aircraft cabins.
