Description

Technology Field

[0001] The present invention relates to a container provided with a heat-shielding coating layer for preventing fire spread, and more specifically, to a container provided with a heat-shielding coating layer for preventing fire spread that is configured to provide an internal parking space for parking vehicles or for short- and long-distance transport, detect fire occurrences and fire precursors in vehicles during the parking and transport process, and suppress the fire by spraying a fire extinguishing substance when a fire occurs, while simultaneously minimizing the transfer of heat to the outside. Background Technology

[0002] Generally, an electric vehicle is a vehicle powered by electricity, which drives the vehicle by rotating a motor with electricity stored in a battery.

[0003] These electric vehicles offer eco-friendly advantages in terms of fuel as they use electricity, lower fuel costs compared to gasoline, and produce less noise while driving than vehicles using regular gasoline, diesel, or LPG. Additionally, they generate no exhaust gases, leading to a gradual increase in sales.

[0005] As mentioned above, electric vehicles have the advantage of being eco-friendly, but if a fire occurs due to external impact or internal short circuit, the battery will burn completely until it is completely burned. Once a battery cell catches fire, the fire does not go out until it is completely burned, and since the capacity and size of the battery are quite large, in most cases, the vehicle is completely burned.

[0006] In other words, the batteries currently used in electric vehicles are structured so that when an internal short circuit or overcurrent occurs, the battery's internal fuse blows and the relay is cut off. Since the negative electrode active material of the battery cell supplies materials such as carbon and the positive electrode active material supplies oxygen, once a fire breaks out, it explodes and burns completely.

[0007] In addition, a short circuit can occur when the positive and negative electrodes come into direct contact inside the battery cell, and if an internal short circuit occurs, a fire may result from sudden overheating. Furthermore, fires caused by thermal runaway, a phenomenon in which the battery cell temperature rises rapidly and releases heat, are also occurring frequently.

[0008] Therefore, in the event of a fire in an electric vehicle, as mentioned above, since the fire usually persists until the vehicle is completely burned, isolating the vehicle from the outside can prevent the heat and toxic gases caused by the fire from spreading to the outside.

[0010] As an example of prior art proposed for this purpose, there is Korean Published Patent No. 10-2024-0140525 (published September 24, 2024), which relates to a "protective cover for preventing fire spread in electric vehicles." This prior art provides a protective cover made of aramid fiber, a flame-retardant material, and is positioned to cover the exterior of an electric vehicle where a fire has occurred. Prior art literature

[0011] Republic of Korea Published Patent No. 10-2024-0140525 (Published September 24, 2024) The problem to be solved

[0012] To solve the above problems, the present invention aims to provide a container equipped with a fire spread prevention heat-shielding coating layer that improves convenience for parking or transportation by providing a space for an electric vehicle to be parked, suppresses the fire by spraying a fire extinguishing substance upon detecting the occurrence of a fire or fire precursor in the parked electric vehicle, and simultaneously prevents the spread of fire by minimizing the transfer of heat caused by the fire to the outside through a heat-shielding coating layer provided on the inner surface.

[0014] In addition, the present invention aims to provide a container equipped with a heat-shielding coating layer for preventing fire spread, which improves fire suppression efficiency by perforating the lower part of the electric vehicle where a fire has occurred so that a fire extinguishing substance is directly delivered to the battery, which is the main cause of the electric vehicle fire. means of solving the problem

[0016] A heat-shielding coating layer formed on the inner surface of the main body to shield heat caused by a fire in the vehicle from being transferred to the outside;

[0017] A fire extinguishing module installed on the main body to spray fire extinguishing material toward the parking space;

[0018] It is characterized by including a fire detection means for detecting fire and fire precursor phenomena occurring in the above parking space.

[0020] In addition, the heat barrier coating layer is characterized by being formed by applying a coating liquid, formed by mixing a base binder, a heat reflective material, a heat resistance reinforcing material, a filler, and an additive, to the inner wall of the main body at least once.

[0022] In addition, the fire extinguishing module is characterized by comprising: a pipeline provided in the main body that provides a path for the movement of a fire extinguishing substance; a plurality of spray nozzles installed in the pipeline at intervals to spray the fire extinguishing substance to the outside; and a drilling means provided in the main body that drills into the lower part of the vehicle where the fire has occurred to form an inlet hole into which the fire extinguishing substance sprayed from the spray nozzles is injected into the vehicle battery.

[0024] At this time, the drilling means is characterized by including a rail provided on the main body and a drilling machine movably installed on the rail to drill the lower part of a parked vehicle and to communicate a battery provided inside the vehicle with the outside.

[0026] Furthermore, the above-described drilling machine is characterized by including a driving block installed to be movable along the rail, a wedge provided on the driving block with a pointed tip, and a driving unit that moves the wedge vertically upward while operating by an applied power source and signal. Effects of the invention

[0027] The present invention, as described above, has the effect of minimizing damage to the electric vehicle by enabling rapid suppression of a fire that occurs while the electric vehicle is parked or transported, and minimizing economic loss by preventing the spread of the fire and reducing surrounding damage.

FIG. 2 is an exemplary diagram illustrating a fire extinguishing module constituting the present invention. FIG. 3 is an exemplary diagram illustrating a perforating means constituting the present invention. Specific details for implementing the invention

[0033] Hereinafter, a preferred embodiment of a container provided with a heat-shielding coating layer for preventing fire spread according to the present invention will be examined in detail with reference to the attached drawings.

[0035] First, a container (1) provided with a heat-shielding coating layer for preventing fire spread according to the present invention comprises a main body (10) provided with a parking space (11) in which a vehicle is parked, a heat-shielding coating layer (20) formed on the inner surface of the main body (10) to shield heat caused by a fire in the vehicle from being transferred to the outside, a fire extinguishing module (30) installed on the main body (10) to spray a fire extinguishing substance toward the parking space (11), and a fire detection means (40) for detecting a fire and fire precursor phenomenon occurring in the parking space (11).

[0037] The above main body (10) can utilize a standard cargo container with a parking space (11) provided inside.

[0038] This main body (10) is formed in the shape of an enclosure with a parking space (11) formed inside, and on one side, a door-type lamp (12) is provided to open or close the parking space (11) and to assist in the process of an electric vehicle entering or exiting the parking space (11), and on the outer surface, a monitoring window (13) for checking the internal situation, a fire extinguishing module (30) described later, and a control panel (14) for checking and controlling the operating status of a fire detection means (40) and a charging means (50) may be provided.

[0039] Meanwhile, the main body (10) may be positioned in a state where it is seated on a separate support frame (), the support frame () may provide space necessary for the installation of the fire extinguishing module (30) and charging means (50) described later, and may be provided with a torsion spring (not shown) that supports the main body (10) from below and elastically supports the transmitted load.

[0040] The above ramp (12) provides the function of a door for opening or closing the above parking space (11), and at the same time, when opened, it is positioned to be inclined downward at a predetermined angle toward the ground to support the entry and exit of electric vehicles.

[0041] The above-mentioned observation window (13) is made of a transparent window that allows the parking space (11) to be viewed from the outside, and a number of them may be provided on the main body (10) at intervals from each other.

[0042] And the above control panel (14) is composed of a display and control buttons provided on the outer surface of the main body (10), so that the operating status of the fire extinguishing module (30), fire detection means (40), and charging means (50) described later can be checked on the display and controlled through the control buttons.

[0043] The operation and specific structure of such a control panel (14) are known, so a detailed description and illustration will be omitted.

[0045] The above heat-blocking coating layer (20) is formed on the inner surface of the main body (10) to prevent heat from being conducted to the outside of the main body (10) in the event of a fire in a vehicle parked in a parking space (11), and is formed by applying a coating liquid formed by mixing a base binder, a heat-reflective material, a heat-resistant reinforcing material, a filler, and an additive to the inner wall of the main body (10) at least once.

[0046] The above base binder is composed of a silicone-based binder made of a silicone-based resin or a polymer-based binder made of any one of epoxy resin or polyurethane.

[0047] Here, the silicone-based binder has excellent heat resistance, chemical resistance, and insulation properties, and has the advantage of being applicable in high-temperature environments, while the polymer-based binder is very stable at high temperatures and has the advantage of excellent heat resistance.

[0048] The above-mentioned heat-reflective material is a material having the property of reflecting heat, and is composed of titanium dioxide or aluminum oxide or any one of a metal powder or ceramic composed of aluminum, copper, or silver.

[0049] The above heat-resistant reinforcing material is composed of any one of alumina, silica, and nitride, and consists of a metal oxide that is stable at high temperatures.

[0050] The above filler is composed of either silica or alumina and has the function or effect of increasing the mechanical strength, durability, and wear resistance of the coating layer.

[0051] The above additive controls the properties of the coating layer and regulates the drying and curing processes after application, and stabilizers or antioxidants are applied to enhance the durability of the coating layer and maintain effective protective performance even under long-term heat exposure.

[0053] The heat-blocking coating layer (20) is formed by adding 60 to 70 weight% of the base binder, 10 to 15 weight% of the heat-reflective material, 10 to 15 weight% of the heat-resistant reinforcing material, 5 to 8 weight% of the filler, and 3 to 5 weight% of the additive, and then stirring to form a coating liquid. The formed coating liquid is then applied to the inner surface of the main body (10) using a spray device and cured, and it is preferable to form the coating layer by overlapping the curing process at least once after application.

[0054] The heat-shielding coating layer (20) formed as described above is formed on the inner surface of the main body (10) to minimize the transfer of heat to the outside in the event of a fire in an electric vehicle parked in a parking space (11).

[0056] Meanwhile, the heat-shielding coating layer (20) may be formed on a separate sheet and then attached to the main body (10). The sheet used at this time may be made of a flame-retardant material and may be fixed integrally to the main body (10) using a bonding means such as a bonding bolt, a bonding nail, or an adhesive.

[0057] Forming a heat shielding coating layer (20) on a sheet is relatively easier to manage and maintain compared to forming it directly on the inner surface of the main body (10). As time passes, the heat shielding coating layer (20) oxidizes due to contact with air, and as its function and effect decrease, the function and effect of the heat shielding coating layer (20) can be maintained by replacing only the sheet.

[0058] In addition, applying and curing directly to the inner surface of the main body (10) requires a separate device for application and the main body cannot be used during the application and curing process, but attaching a sheet forming a heat-blocking coating layer (20) has the advantage of allowing the main body (10) to be used even during the sheet replacement process, as the time required for replacing the sheet is relatively short.

[0060] The above fire extinguishing module (30) extinguishes a fire by spraying a fire extinguishing substance onto an electric vehicle parked in a parking space (11) when a fire occurs in the electric vehicle.

[0061] To this end, the fire extinguishing module (30) comprises a pipeline (31) provided in the main body (10) to provide a path for the fire extinguishing substance to move, a plurality of spray nozzles (32) installed at intervals in the pipeline (31) to spray the fire extinguishing substance to the outside, and a drilling means (33) provided in the main body (10) to drill the lower part of the vehicle where the fire has occurred and to form an input hole (not shown) into which the fire extinguishing substance sprayed from the spray nozzles (32) is injected into the vehicle battery.

[0063] The above pipeline (31) is provided in the main body (10) to provide a path for the extinguishing substance to move, wherein the extinguishing substance is intended to suppress a fire and may consist of any one of carbon dioxide or chemical powders such as sodium chloride, ammonium phosphate, or potassium chloride, which have high efficiency in suppressing electric fires.

[0064] In addition, one end of the pipeline (31) is exposed to the outside of the main body (10) so that it can receive fire extinguishing material from the outside in the event of a fire.

[0065] Here, the pipeline (31) can be provided in the horizontal and vertical directions inside the main body (10), and can be provided on the floor, side wall, and ceiling, respectively.

[0067] The above spray nozzles (32) are installed in the pipeline (31) at intervals from each other and spray the moved fire extinguishing material toward the parking space (11).

[0068] Here, the spray nozzle (32) is used to spray fire extinguishing material to the outside, and there are no special restrictions on the spray shape or structure. However, it is preferable that the spray nozzle (32) installed on the pipeline (31) positioned on the bottom side of the main body (10) be able to discharge fire extinguishing material in a straight line over a predetermined distance so as to be injected into the injection hole formed by the drilling means (33) described later.

[0070] The above-mentioned drilling means (33) drills the lower part of a vehicle where a fire has occurred to form an inlet hole into which a fire extinguishing substance is introduced, and includes a rail (331) provided on the main body (10) and a drilling machine (332) movably installed on the rail (331) to drill the lower part of a parked vehicle and communicate a battery provided inside the vehicle with the outside.

[0071] The above rail (331) is provided on the bottom surface of the main body (10) and can be installed independently in each area after dividing the main body (10) into any multiple areas.

[0072] The above rail (331) is for adjusting the position of the drilling machine (332) because the vehicles parked in the parking space (11) are of various types, and the position of the battery installed in each vehicle is different, and the position of the drilling machine (332) must be adjusted according to the position of the battery.

[0073] The above-mentioned drilling machine (332) is movably installed on the rail (331) to drill the lower part of the vehicle and form an inlet hole into which a fire extinguishing substance is introduced. To this end, the above-mentioned drilling machine (332) includes a driving block (333) movably installed along the rail (331), a wedge (334) provided on the driving block (333) with a pointed tip, and a driving unit (335) that moves the wedge (334) vertically upward while operating by an applied power source and signal.

[0074] The above-mentioned driving block (333) is movably installed on the above-mentioned rail (331), and the rail (331) and the driving block (333) may be made of a known LM guide, but this is one embodiment and various modifications are possible.

[0075] Here, the driving block (333) is provided with a discharge nozzle (336) for spraying fire extinguishing material through an input hole perforated through the wedge (334).

[0076] The wedge (334) is provided on the driving block (333) and positioned so as to be able to move vertically up and down, and has a pointed tip formed to pierce the lower part of the vehicle in contact with it to form an insertion hole.

[0077] The above driving unit (335) moves the wedge (334) up and down, and operates by the applied power and signal to move the wedge (334) up and down to drill the underside of the vehicle, or drills the underside of the vehicle by rotating the wedge (334) and raising it from the underside of the vehicle.

[0078] The drilling machine (332) formed as described above moves the driving block (333) to a position for forming an input hole and operates the driving unit (335) to form an input hole in the lower part of the vehicle with a wedge (334).

[0079] Afterwards, a fire extinguishing substance is sprayed from the discharge nozzle (336) provided in the driving block (333) through the input hole, thereby directly spraying the fire extinguishing substance toward the vehicle's battery side to suppress the fire or minimize its spread.

[0081] The above fire detection means (40) is provided in the main body (10) to detect the occurrence of a fire or a fire precursor in a vehicle parked in the parking space (11), and includes a plurality of fire detection sensors provided at mutually spaced positions in the parking space (11).

[0082] Here, the fire detection sensor may include a combination of sensors capable of detecting the occurrence of a fire or fire precursors, such as a heat detection sensor that detects heat, a carbon dioxide detection sensor that detects the concentration of carbon dioxide, and a flame detection sensor that detects flames.

[0084] Meanwhile, the main body (10) of the present invention is further provided with a charging means (50) for charging the battery of an electric vehicle, wherein the charging means (50) may be wired, wireless, or both, and receives electricity by communicating with a power supply unit separately provided outside the main body (10) through a cable.

[0085] Here, if the above charging means (50) is wireless, a configuration for wireless charging may be provided on the bottom surface of the main body (10), and may be performed in either an inductive charging method or a magnetic resonance method.

[0086] Preferably, a magnetic resonance method is used, which has a relatively faster charging speed and is less critical for position alignment; however, due to the complexity of the magnetic resonance system design and the standardization of parking spaces, an induction method requiring precise position alignment may be applied.

[0088] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art can make various modifications and variations from this description.
