Description

[Technical Field]

[0001] The present invention relates to a portable storage device for extinguishing battery fires, and more specifically, to a device that detects signs of fires involving batteries, including lithium-ion batteries, and electronic devices, and extinguishes the fire in the early stages by pulling in the electronic devices. [Background technology]

[0002] With the recent development of electronic devices, modern people have come to use a variety of electronic devices such as mobile phones, tablets, and laptops. These electronic devices generally contain lithium-ion batteries that are built into or attached to the device, but these lithium-ion batteries are vulnerable to high temperatures and shocks, and there has been a significant increase in the number of cases where fires have occurred, resulting in loss of life and damage to property.

[0003] Recently, in particular, many people have been carrying such electronic devices and batteries on board aircraft for business trips, travel, etc., which has led to the emergence of a fire risk on board aircraft.

[0004] The number of fires on aircraft accounts for approximately 0.003% of the approximately 400,000 fires that have occurred over the past 10 years, which is a small percentage of the total number of fires.However, because it is difficult to respond appropriately to fires caused by batteries on aircraft, the damage caused by these fires is calculated to be the largest among the average damage amounts.

[0005] Therefore, in order to minimize the damage to property and human life caused by a battery fire, a device that can immediately respond to the battery fire at an early stage and extinguish the fire in its early stages is needed.

[0006] Meanwhile, such a battery fire suppression technology is described in Patent Document 1: Korean Utility Model Application No. 20-2022-0002961. [Prior art documents] [Patent documents]

[0015] Referring to Figures 1 to 6, one embodiment of the present invention is a portable storage device for suppressing battery fires, which includes an outer shell, a flame-retardant part, a moisture-permeable part, an opening / closing part, a slide fastener, a barrier film, a storage part, a fire-extinguishing part, an inner shell, a storage space, a sensor part, a power supply part, and a lamp.

[0016] The portable battery fire suppression storage device includes an outer shell and a storage section.

[0017] The outer shell (100) includes a flame-retardant portion (110), a moisture-permeable portion (120), and an opening / closing portion (130).

[0018] The flame-retardant part can be made of cloth, textile, silicone, leather, fur, stainless steel SUS304, SUS303, aluminum, metal, etc. It can also be made of various blends of ordinary cotton and plastic with flame-retardant coating inside, PBI para-aramid, meta-aramid, and anti-static fiber, and can be used at temperatures above 1600°C by using oxidized fiber blended aramid, silicone, or flame-retardant coated aramid fiber. The flame-retardant part is located on the front and back of the portable storage.

[0019] The moisture-permeable portion (120) is connected to the flame-retardant portion and is connected to the flame-retardant portion on the left or right side of the portable storage device in one embodiment of the present invention. In this case, the moisture-permeable portion releases heat, moisture, and oxygen through the spaces between the fibers, but prevents external oxygen from entering, reducing the amount of oxygen inside and providing a sealing effect.

[0020] The moisture permeable portion is a combination of materials such as PTFE and has heat resistance, flame retardancy, and moisture permeability for discharging heat, moisture, and oxygen to the outside.

[0021] The opening / closing portion 130 is located at the top end of the flame-retardant portion and the moisture-permeable portion.

[0022] The opening and closing part includes a slide fastener (131) and a barrier film (132), the slide fastener is made of a corrosion-resistant metal or plastic material, and the pull tab of the slide fastener is made of a heat-resistant material.

[0023] The barrier film is located below the slide fastener and blocks external oxygen from being supplied to the inside.

[0024] The storage section is formed by combining a flame-retardant section, a moisture-permeable section, and an opening / closing section.

[0025] The receiving part includes a fire extinguishing part, an inner skin part, and a receiving space, and one end surface of the fire extinguishing part is attached to or installed on the inner surface of the flame retardant part.

[0026] In one embodiment of the present invention, the fire extinguishing part is manufactured in a pouch shape and attached to one end surface of the flame retardant part using an adhesive.

[0027] The fire extinguishing unit can be attached to only one side of the inner surface of the flame-retardant unit located at the front of the portable storage device, or to all sides of the inner surfaces of the flame-retardant units on both the front and rear of the portable storage device.The fire extinguishing agent contained in the fire extinguishing unit can be a solid aerosol made of KNO3, FK-5-1-12, an encapsulated product of a halogen-based compound, or sodium chloride powder, sodium carbonate powder, lithium chloride powder, copper powder, graphite powder, dry sand, glass powder, expanded vermiculite powder, dolomite powder, zirconium silicate powder, etc.

[0028] In a preferred embodiment of the present invention, a fire extinguishing agent in capsule form, which is an encapsulated form of a solid aerosol composed of KNO3 or the like, FK-5-1-12, or a halogen-based compound, or a fire extinguishing agent in the form of sodium chloride powder, sodium carbonate powder, lithium chloride powder, copper powder, graphite powder, dry sand, glass powder, expanded vermiculite powder, dolomite powder, or zirconium silicate powder, or a liquid fire extinguishing agent may be introduced into the pouch.

[0029] In one embodiment of the present invention, as shown in Figure 4, when the temperature inside the portable storage device rises due to the temperature of a ignited battery introduced into the portable storage device for battery fire extinguishing, the capsule-shaped fire extinguishing agent expands and vaporizes due to the temperature and is sprayed from the pouch. At this time, the internal temperature of the storage unit is lowered by the fire extinguishing agent, which has the effect of expelling oxygen from the storage unit to the outside.

[0030] The inner cover (220) is connected to separate the fire extinguishing unit from the storage space. One end of the inner cover is positioned to contact the other end of the fire extinguishing unit. The lower end of the inner cover is connected to the bottom of the outer cover and both side surfaces of the inner cover are connected to the side surfaces of the outer cover.

[0031] The storage space (230) is formed on the other end surface of the inner skin portion, and provides a space large enough to accommodate a portable battery or electronic device.

[0032] In this case, the sewing thread used for joining the flame-retardant part and the moisture-permeable part or the flame-retardant part and the opening and closing part of the portable storage device for battery fire suppression in a preferred embodiment of the present invention is made of aramid fiber and has an average tear strength of 10 N or more.

[0033] In one embodiment of the present invention, the inner layer is a mesh with a number of holes formed therein, allowing the fire extinguishing agent inside the fire extinguishing unit to be uniformly sprayed onto the ignited battery when it expands and is sprayed. The inner layer also forms a space between the fire extinguishing agent and the ignited battery, preventing the fire extinguishing agent from solidifying in a specific area.

[0034] Since the upper end of the inner cover is not connected to the opening / closing part, the used fire extinguishing part can be replaced through the opened upper opening / closing part by opening the slide fastener of the opening / closing part.

[0035] As can be seen in Figure 5, the battery fire suppression portable storage device includes the sensor unit (300) which includes a sensor (310) and a power supply unit (320). The sensor is placed in the internal space and then connected to the power supply unit installed on the outer surface of the outer shell via an electric wire. The electric wire is flame-retardant, fire-resistant, or heat-resistant, so that it can be used even in a fire situation. The sensor is characterized by transmitting a fire alarm to a user's receiver if it detects an internal temperature of 140°C or higher.

[0036] In another embodiment of the present invention, the sensor may be used as a battery-less sensor. The battery-less sensor may be a sensor using a thermoelectric element that reacts to heat generated inside, a bimetal sensor, a piezoelectric sensor, a piezo sensor, or the like. The battery-less sensor is disposed in the interior space and then connected to a lamp installed on the outer surface of the outer casing via an electric wire. In this case, the electric wire may be a flame-retardant electric wire, a fire-resistant electric wire, a heat-resistant electric wire, or the like, so that the sensor can be used even in a fire situation. In one embodiment of the present invention, after detecting internal heat through the battery-less sensor, if the sensor detects that the internal temperature is outside of a normal range, a lamp installed on the outer casing may emit a signal to warn of a fire.

[0037] A portable storage device for battery fire suppression according to one embodiment of the present invention can be used as a portable device on airplanes, trains, automobiles, subways, etc. More specifically, when using the portable storage device for battery fire suppression, if a user or finder recognizes that a portable battery or electronic device has overheated or caught fire, they insert the battery or electronic device into the portable storage device and then close the opening and closing part as shown in Figure 6. Thereafter, the slide fastener and barrier membrane of the opening and closing part block the supply of external oxygen to prevent the spread of the fire, and the fire-extinguishing agent of the fire-extinguishing part extinguishes the fire in the electronic device or battery inside the portable storage device. The moisture-permeable part blocks the inflow of external oxygen generated during the fire suppression process and discharges heat, moisture, and oxygen generated inside, reducing the amount of oxygen inside and achieving a sealed effect.

[0038] Meanwhile, the embodiments of the present invention disclosed in this specification and the drawings are merely specific examples presented to easily explain the technical contents of the present invention and to facilitate understanding of the present invention, and are not intended to limit the scope of the present invention. It is obvious to a person skilled in the art to which the present invention pertains that other modifications based on the technical idea of ​​the present invention can be implemented in addition to the embodiments disclosed herein.
