Description

Technical Field

[0001] This invention relates to the field of fire extinguishing equipment technology, specifically to a safety protection box. Background Technology

[0002] In recent years, with the widespread use of portable electronic devices and the surge in lithium battery air transport, fires and smoke incidents caused by lithium batteries have frequently occurred in the global aviation sector, posing a serious threat to aviation safety. The core risk of such incidents stems from the thermal runaway chain reaction of lithium batteries: mechanical compression, short circuits, or high temperatures may trigger electrolyte decomposition, releasing toxic gases and large amounts of heat, which can rapidly lead to explosions or fires in the confined cabin environment.

[0003] However, existing aviation emergency response methods have significant limitations. Lithium battery combustion causes serious safety damage to the cabin interior, and there is currently a lack of dedicated devices to suppress the combustion of burning materials, making it easy for the fire to spread inside the cabin. Summary of the Invention

[0004] The purpose of this invention is to develop a safety protection box that can contain and suppress the combustion of burning materials, prevent the spread of fire, quickly handle the runaway of lithium batteries, and effectively isolate them.

[0005] This invention is achieved through the following technical solution:

[0006] A safety protection box, comprising:

[0007] Box;

[0008] The lid is attached to the box body;

[0009] The box body and the box cover are provided with a latch. The box cover is provided with an observation window assembly for observing the inside of the box body, a water inlet assembly for injecting liquid into the box body, and a filter assembly. The observation window assembly is located at the center of the top of the box cover. The water inlet assembly is located on the side of the observation window assembly near the latch. The filter assembly is located on the side of the water inlet assembly near the latch.

[0010] The layered structure of the box lid and box body includes, from the inside out, an inner lining, insulation cotton, and an outer shell.

[0011] Optionally, the inner lining is made of heat-resistant stainless steel, the insulation cotton is made of ceramic fiber material, and the outer shell is made of engineering plastic.

[0012] Optionally, the inner lining, insulation cotton, and outer shell are sequentially bonded together with heat-resistant silicone.

[0013] Optionally, bolts are provided on the inner lining plate and the outer shell, which are arranged in the direction of the heat insulation cotton.

[0019] Optionally, the filter assembly includes an exhaust trough located on the top of the cover. The exhaust trough includes a plurality of evenly arranged circular or strip-shaped air holes. A filter trough is located on the top of the exhaust trough. A filter box is located inside the filter trough. A baffle that is detachably connected to the filter trough is located on the top of the filter box. A plurality of strip-shaped air outlet troughs are evenly arranged on the baffle.

[0020] The beneficial effects of this invention are:

[0021] In the event of lithium battery thermal runaway, the enclosure can be placed inside to quickly handle the runaway and effectively isolate the battery, preventing it from igniting and causing a fire. It features a heat-resistant stainless steel inner lining, with fire-resistant insulation materials such as ceramic fiber between the lining and the outer shell to prevent excessively high temperatures on the outer wall due to internal combustion. A water inlet assembly allows for the injection of extinguishing agents (such as water or other inert liquids) to quickly reduce the lithium battery temperature or suppress the fire caused by thermal runaway. A filter assembly releases internal pressure and filters toxic gases released during thermal runaway in emergencies (such as lithium battery thermal runaway), preventing environmental pollution and personnel poisoning. An observation window allows for observation of the internal situation, preventing secondary injuries from opening the enclosure before the fire is controlled or extinguished.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-3 As shown, the present invention discloses a safety protection box, which is rectangular in shape and includes an open box body 1 and a box cover 2. One side of the opening of the box cover 2 is hinged to one side of the opening of the box body 1. Two matching latches 5 are respectively provided on the other side of the box cover 2 and the box body 1 opposite to the hinged side. A handle 6 is provided on the box body 1 between the two latches 5.

[0031] The opening edge of the lid 2 is provided with a high-temperature resistant sealing ring 400 that matches the opening edge of the box body 1. After the lid 2 is closed on the box body 1 and the latch 5 is locked, the sealing ring 400 fills the gap between the lid 2 and the box body 1, so that the inside of the protective box is sealed.

[0032] The bottom of the case 1 and the top of the case lid 2 are respectively provided with two long strip-shaped protrusions 13. The protrusions 13 are provided with nylon hook and loop fasteners. The corresponding hook and loop fasteners are provided in the aircraft cabin or in the environment where the protective case is placed to secure the protective case. In addition, the corresponding hook and loop fasteners can also be provided on the packaging that contains other emergency items so that other emergency items can be fixedly placed on the protective case.

[0033] The cover 2 and the side of the box body 1 where the latch 5 is located are respectively provided with corresponding through holes 3. After the cover 2 and the box body 1 are closed, the through hole 3 is provided with a lead seal 4, which serves as an anti-tampering mark to confirm that the protective box has not been opened without authorization.

[0034] The layered structure of the protective box, namely the layered structure of the box cover 2 and the box body 1, includes, from the inside out, an inner lining plate 100, a heat insulation cotton 200, and an outer shell 300. The inner lining plate 100 is made of heat-resistant stainless steel or other heat-insulating metals, the heat insulation cotton 200 is made of ceramic fiber or other fire-resistant materials, and the outer shell 300 is made of engineering plastic or other heat-resistant plastics.

[0035] The inner lining plate 100, insulation cotton 200, and outer shell 300 can be bonded together using heat-resistant silicone. Alternatively, bolts can be installed on the inner lining plate 100 and outer shell 300, oriented towards the insulation cotton 200. The inner ends of the bolts on the inner lining plate 100 and outer shell 300 are positioned at the insulation cotton 200, providing a clamping and fixing effect. Bolt washers are also provided at the bolt locations on the inner lining plate 100 and outer shell 300. The bolts are ceramic bolts, and the bolt washers are mica washers, both providing excellent heat insulation and effectively ensuring heat isolation.

[0036] The inner lining plate 100 and the outer shell 300 can also be snapped together, with the edge of the inner lining plate 100 snapping into the edge of the outer shell 300. The edges of the inner lining plate 100 or the outer shell 300 are bent accordingly. The edge of the inner lining plate 100 is provided with a boss or a groove, and the edge of the outer shell 300 is provided with a corresponding groove or boss. The contact parts of the boss and groove are provided with heat-insulating and fire-resistant material to prevent heat from being transferred to the outer shell 300. The heat-insulating and fire-resistant material can be ceramic fiber.

[0037] The top of the cover 2 is equipped with a water inlet assembly, an observation window assembly, and a filter assembly. After the thermal runaway lithium battery and other flammable items are placed in the box 1, fire extinguishing agent, such as water or other inert liquid, is injected into the box 1 through the water inlet assembly to quickly reduce the temperature of the lithium battery or suppress the thermal runaway fire. The observation window assembly is used to view the internal condition of the box 1, and the filter assembly is used to release the internal pressure or gas of the box 1.

[0038] The observation window assembly is located at the top center of the lid 2 to maximize the view inside the box. The water inlet assembly is located on the side of the observation window assembly near the handle 6 and the latch 5 to allow observation of the water filling process. The filter assembly is closer to the handle 6 and the latch 5 than the water inlet assembly, ensuring that when the protective box is carried by the handle 6, the filter assembly is higher than the water inlet assembly. When water is poured into the protective box through the water inlet assembly, the maximum water volume (liquid level at the water inlet assembly) will not reach the filter assembly, preventing water from entering the filter assembly and causing filter failure.

[0039] The water inlet assembly includes a water inlet 7 located on the top of the tank cover 2, and a screw cap 8 is internally threaded onto the water inlet 7. By opening the screw cap 8, liquid can be injected into the tank 1 through the water inlet 7, and by tightening the screw cap 8, the water inlet 7 can be closed.

[0040] The observation window assembly includes an observation opening 9 located at the top of the lid 2, with a transparent observation window 10 inside the observation opening 9. Through the observation window 10, the fire situation inside the container 1 can be observed, preventing serious consequences from being caused by opening the lid 2 if the fire is not under control. The observation opening 9 is located at the center of the top of the lid 2 to provide the maximum viewing angle for the situation inside the container 1.

[0041] The filter assembly includes an exhaust trough located on the top of the cover 2. The exhaust trough includes multiple evenly arranged circular or strip-shaped air holes. A filter trough is located on top of the exhaust trough, and a filter box 11 is located inside the filter trough. A baffle 12, detachably connected to the filter trough, is located on the top of the filter box 11. Multiple strip-shaped air outlet slots are evenly arranged on the baffle 12. A protective film (not shown in the figure) is provided on the top surface of the baffle 12. Before the protective box is put into use, the protective film can prevent impurities and water from entering the filter box 11.

[0042] In the event of thermal runaway of a lithium battery, it can be placed inside the enclosure 1 to prevent the lithium battery from igniting and causing a fire. It is equipped with a heat-resistant stainless steel inner lining plate 100, and a heat insulation cotton 200 made of fire-resistant materials such as ceramic fiber is installed between the inner lining plate 100 and the outer shell 300 to prevent the outer wall temperature of the enclosure 1 from becoming too high due to internal combustion. The water inlet assembly can inject fire extinguishing agent (such as water or other inert liquids) into the enclosure to quickly reduce the temperature of the lithium battery or suppress the fire caused by thermal runaway of the lithium battery. The filter assembly can release the internal pressure in an emergency (such as thermal runaway of the lithium battery) and filter the toxic gases released by thermal runaway to prevent external environmental pollution and personnel poisoning. The observation window assembly can be used to observe the internal situation and prevent secondary injury caused by opening the enclosure 1 before the fire is controlled or extinguished.

[0043] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
