Description

Vehicle fire suppression device and method capable of reusing extinguishing liquid

[0001] Various embodiments of the present disclosure relate to a vehicle fire suppression device and method capable of reusing a fire extinguishing liquid.

[0002] Modern electric vehicles utilize high-capacity lithium-ion batteries, and due to their high energy density, these batteries pose a risk of fire caused by various factors such as impact, overcharging, and thermal runaway. In particular, unlike typical fires, lithium-ion battery fires are difficult to extinguish because they release reactive gases, such as oxygen, under high temperatures, triggering a chain reaction of thermal runaway. Existing firefighting equipment does not adequately account for the specific characteristics of electric vehicle battery fires, resulting in limited effectiveness in suppression; further improvements are needed in terms of preventing re-ignition and firefighting efficiency.

[0003] Various improvement efforts have been made to solve the problems of these existing methods. For example, according to Registered Patent Publication No. 10-2682814 (July 3, 2024, Title of Invention: Firefighting System for Electric Vehicle-Only Parking Area), the disclosure provides a water tank space of a predetermined size to accommodate electric vehicles, enabling the suppression of a fire by supplying water into the tank or creating a vacuum.

[0004] In addition, according to Korean Patent Publication No. 10-2024-0159051 (November 5, 2024, Title of Invention: Fire Extinguishing Device for Electric Vehicles), a fire extinguishing device is provided that can extinguish a fire occurring in a battery by drilling a hole in the battery where the fire has occurred and directly spraying extinguishing water through the hole.

[0005] However, water tank-based fire suppression methods are difficult to apply in all fire situations due to the mobility and space constraints of electric vehicles, and their efficiency may be reduced as they require large quantities of water. Additionally, the method of directly puncturing the battery requires physical damage, which not only increases the risk of explosion but also limits response speed in emergency situations due to the need for precise work.

[0006] Accordingly, the problem that the present disclosure aims to solve is to provide a vehicle fire suppression device and method capable of reusing a fire extinguishing agent, which can achieve rapid and accurate fire suppression by effectively spraying a fire extinguishing agent onto the heat source of an electric vehicle battery fire for the purpose of resolving the problems of existing fire suppression methods, thereby minimizing fire spread to shorten suppression time and suppressing the possibility of re-ignition.

[0007] Another problem that the present disclosure aims to solve is to provide a vehicle fire suppression device and method capable of reusing fire extinguishing fluid, which can reduce waste of fire extinguishing fluid and prevent environmental pollution through a system capable of recovering and recycling the fire extinguishing fluid used in vehicle fires, thereby enabling efficient resource utilization and continuous supply of fire extinguishing fluid.

[0008] Another problem that the present disclosure aims to solve is to provide a vehicle fire suppression device and method capable of reusing extinguishing liquid, which can achieve safer and more convenient fire suppression by having mobility and a foldable structure, allowing for rapid deployment and operation in a fire situation, and by automatically detecting the fire condition and responding flexibly.

For illustrative purposes, numerous specific details are disclosed in the following description to aid in a general understanding of one or more aspects. However, it will be apparent to those skilled in the art that these aspects may be practiced without such specific details. The following description and the accompanying drawings describe specific exemplary aspects of one or more aspects in detail. However, these aspects are exemplary, and some of the various methods in the principles of the various aspects may be used, and the descriptions are intended to include all such aspects and their equivalents. Specifically, terms such as “exemplary,” “example,” “aspect,” and “example” as used herein may not be interpreted as implying that any described aspect or design is superior or advantageous over other aspects or designs.

[0051] Hereinafter, identical or similar components are assigned the same reference numeral regardless of drawing symbols, and redundant descriptions thereof are omitted. Furthermore, in describing the embodiments disclosed in this specification, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions may obscure the essence of the embodiments disclosed in this specification. Additionally, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings.

[0052] Although terms such as first, second, etc. are used to describe various elements or components, it goes without saying that these elements or components are not limited by these terms. These terms are used merely to distinguish one element or component from another. Therefore, it goes without saying that the first element or component mentioned below may be the second element or component within the technical scope of the present disclosure.

[0053] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning commonly understood by those skilled in the art to which this disclosure pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0054] Furthermore, the term "or" is intended to mean an implicit "or" rather than an exclusive "or." That is, unless otherwise specified or evident from the context, "X uses A or B" is intended to mean one of the natural implicit substitutions. In other words, if X uses A; if X uses B; or if X uses both A and B, "X uses A or B" may apply to any of these cases. Additionally, the term "and / or" as used herein should be understood to refer to and include all possible combinations of one or more of the enumerated related items.

[0055] Additionally, the terms “comprising” and / or “comprising” should be understood to mean that such features and / or components are present, but not to exclude the presence or addition of one or more other features, components, and / or groups thereof. Furthermore, unless otherwise specified or clearly evident from the context to indicate a singular form, the singular in this specification and claims should generally be interpreted to mean “one or more.”

[0058] When elements or layers are referred to as being "on" or "on" another element or layer, it includes not only being directly on top of the other element or layer but also cases where another layer or element is interposed in between. On the other hand, when a component is referred to as being "directly on" or "immediately on," it indicates that no other element or layer is interposed in between.

[0059] Spatially relative terms such as "below," "beneath," "lower," "above," and "upper" may be used to easily describe the relationship between one component or other components as illustrated in the drawings. Spatially relative terms should be understood as encompassing different orientations of the element during use or operation, in addition to the directions illustrated in the drawings.

[0060] For example, if a component depicted in a drawing is inverted, a component described as being "below" or "beneath" another component may be placed "above" the other component. Therefore, the exemplary term "below" may encompass both the downward and upward directions. Components may also be oriented in other directions, and accordingly, spatially relative terms may be interpreted according to the orientation.

[0061] The purpose and effects of the present disclosure, and the technical configurations for achieving them, will become clear by referring to the embodiments described in detail below in conjunction with the accompanying drawings. In describing the present disclosure, if it is determined that a detailed description of known functions or configurations might unnecessarily obscure the essence of the present disclosure, such detailed description will be omitted.

[0066] Referring to FIGS. 1 to 15, in one embodiment, a vehicle fire suppression device capable of reusing fire extinguishing liquid is placed in a vehicle where a fire has occurred, and can spray a fire extinguishing liquid provided inside the vehicle fire suppression device onto the vehicle to suppress the fire that has occurred in the vehicle. In addition, the vehicle fire suppression device capable of reusing fire extinguishing liquid can minimize waste of fire extinguishing liquid required for fire suppression by recovering the fire extinguishing liquid sprayed onto the vehicle and spraying the recovered fire extinguishing liquid back onto the vehicle where the fire has occurred in order to reuse the fire extinguishing liquid sprayed onto the vehicle. Furthermore, through continuous reuse of fire extinguishing liquid, the efficiency and economic viability of fire suppression can be increased, thereby reducing dependence on external fire extinguishing resources and enabling rapid and stable fire suppression.

[0067] To this end, a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid may include a main body (100), a fire extinguishing liquid spraying module (200), and a fire extinguishing liquid recovery module (300).

[0068] Here, the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid in FIGS. 1 to 15 is according to one embodiment, and its components are not limited to the embodiments shown in FIGS. 1 to 15 and may be added, changed, or deleted as needed.

[0069] In one embodiment, the main body (100) may include a first housing (110) and a second housing (120).

[0070] In various embodiments, the first housing (110) may have a predetermined space inside and may store various components constituting a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid.

[0071] More specifically, the first housing (110) may have a predetermined width, a predetermined space inside, and may have a rectangular shape that is long in the vertical direction relative to the ground. Here, the predetermined width may be similar to the width of a typical vehicle, but is not limited thereto.

[0072] In various embodiments, the first housing (110) may include a fire extinguishing liquid storage tank (111) formed in at least a portion of the interior and in which fire extinguishing liquid is stored.

[0073] More specifically, the fire extinguishing liquid storage tank (111) can be designed to have a large capacity so that a sufficient amount of fire extinguishing liquid can be stored to stably supply the fire extinguishing liquid required during the fire suppression process.

[0074] In various embodiments, the fire extinguishing liquid storage tank (111) may be made of a flame-retardant and corrosion-resistant material having high durability, thereby allowing the fire extinguishing liquid to be stored for a long period of time without deformation or corrosion occurring and maintaining a stable state.

[0075] In various embodiments, the first housing (110) may be made of a material capable of withstanding vehicle fire (e.g., alumina ceramic, carbon fiber composite, stainless steel, etc.), but is not limited thereto.

[0076] In various embodiments, the first housing (110) may include a heat shield module to block heat from the surroundings and protect the device. The heat shield module is a separate component that may be installed on the outer side or top of the first housing (110) and serves to protect the device from surrounding heat and flames. The heat shield module has an expandable structure and can be unfolded when necessary to block heat and flames generated in the event of a fire from being directly transmitted to the first housing (110).

[0077] More specifically, the heat shield module can be unfolded or folded step by step as needed in the form of a multi-foldable panel. The heat shield module is folded and stored in close contact with the outer side or top of the first housing (110), thereby minimizing the external volume when moving and storing the device. It can be expanded and contracted manually or automatically as needed, and in the case of the automatic method, it may have a structure that unfolds or folds by a control command from the control module (700).

[0078] In various embodiments, the first housing (110) may be connected to the second housing at least in part.

[0079] More specifically, the structure may be such that the first housing (110) is placed on the second housing (120) so that the main body (100) has a '┛' shape, or the structure may be such that the side surface of the first housing (110) is connected to the side surface of the second housing (120).

[0080] Here, the main body (100) of a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid according to various embodiments of the present disclosure is described as having two different housings, a first housing (110) and a second housing (120), as separate components, and being connected and combined with the first housing (110) and the second housing (120), but is not limited thereto, and the first housing (110) and the second housing (120) are expressions set to more clearly designate the location of the main body (100), and the main body (100) may not be divided into the first housing (110) and the second housing (120), but may be implemented as a single housing in the shape of a '┛'.

[0081] In various embodiments, the second housing (120) can be used in a form that is inserted into the lower part of the fire vehicle, as shown in FIG. 1.

[0082] More specifically, the second housing (120) has a predetermined width, and the predetermined width may be equal to or similar to the width of the first housing (110), but is not limited thereto.

[0083] In various embodiments, the second housing (120) may have a foldable structure or a sliding multi-stage structure for the purpose of facilitating storage and movement of the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid.

[0084] For example, the second housing (120) may include a plurality of housing modules (120A, 120B, 120C) and a hinge (122) connecting the plurality of housing modules (120A, 120B, 120C) as shown in FIG. 11, and the plurality of housing modules (120A, 120B, 120C) may be folded and overlapped in a unidirectional or vertical direction as shown in FIG. 12, as the plurality of housing modules (120) have a foldable structure connected through the hinge (122). At this time, since the second housing (120) has a foldable structure, there is a possibility that fire extinguishing liquid leakage may occur between the plurality of housing modules (120A, 120B, 120C), it may include a leakage prevention member (123) to prevent fire extinguishing liquid leakage between the plurality of housing modules (120A, 120B, 120C). Here, the leak prevention member (123) may be made of an elastic flame-retardant material (e.g., sealing, gasket, packing, silicone, etc.), but is not limited thereto.

[0085] As another example, the second housing (120) may include a plurality of housing modules (120A, 120B, 120C) and a sliding rail (124) connecting the plurality of housing modules (120A, 120B, 120C) as shown in FIG. 13, and as the plurality of housing modules (120A, 120B, 120C) have a sliding structure connected through the sliding rail (124), the plurality of housing modules (120A, 120B, 120C) may slide and overlap as shown in FIG. 13. At this time, as the second housing (120) has a sliding structure, there is a possibility that fire extinguishing liquid leakage may occur between the plurality of housing modules (120A, 120B, 120C), so it may include a leakage prevention member (123) to prevent fire extinguishing liquid leakage between the plurality of housing modules (120A, 120B, 120C). Here, the leak prevention member (123) may be made of an elastic flame-retardant material (e.g., sealing, gasket, packing, silicone, etc.), but is not limited thereto.

[0086] In various embodiments, the second housing (120) may be made of the same material as the first housing (110), such as a material that can withstand vehicle fire (e.g., alumina ceramic, carbon fiber composite, stainless steel, etc.), but is not limited thereto.

[0087] In various embodiments, the second housing (120) may be provided with a fire extinguishing liquid recovery space (121) for collecting and storing fire extinguishing liquid sprayed through the fire extinguishing liquid spray module (200) described later.

[0088] Here, the extinguishing liquid recovery space (121) is an empty space formed inside the second housing (120) as illustrated in FIG. 4, and may be a space exposed to the outside through an open portion as at least a portion of the upper surface of the second housing (120) has an open shape. For example, the extinguishing liquid recovery space (121) may be a space formed inside the second housing (120) as the second housing (120) has a '┕┛' shape with an open upper surface. However, it is not limited thereto.

[0089] In various embodiments, the digestion liquid recovery space (121) may be designed to include a plurality of unit recovery spaces having different depths or having a floor surface of the space sloped at a predetermined angle relative to the ground for the purpose of easily collecting the used digestion liquid.

[0090] For example, as illustrated in FIG. 9, the extinguishing liquid recovery space (121) may be designed with a structure in which the bottom surface of the space has a slope of a predetermined angle relative to the ground. This structure induces the extinguishing liquid recovered in the extinguishing liquid recovery space (121) to naturally flow down to a lower position by gravity, thereby allowing the extinguishing liquid to be concentrated at one specific recovery point.

[0091] As another example, the digestion fluid recovery space (121) may include a plurality of unit recovery spaces having different depths, as illustrated in FIG. 10. The plurality of unit recovery spaces may be connected sequentially according to the size of the depth, thereby allowing the digestion fluid to flow down from a unit recovery space with a small depth to a unit recovery space with a large depth, so that the digestion fluid can be concentrated at a specific recovery point. Additionally, each connection part of the plurality of unit recovery spaces may have a structure in which a step is formed due to the difference in depth, and through this step, the digestion fluid may be prevented from flowing back from a unit recovery space with a large depth to a unit recovery space with a small depth.

[0092] In various embodiments, the second housing (120) may include a fire extinguishing fluid collection module to more efficiently collect the fire extinguishing fluid sprayed through the fire extinguishing fluid spray module (200) described below. The fire extinguishing fluid collection module has a foldable wing structure and is a separate component that can be installed on both sides or the bottom of the second housing (120), allowing it to collect a wider range of fire extinguishing fluid and concentrate it into the fire extinguishing fluid recovery space (121).

[0093] More specifically, the fire extinguishing fluid collection module can be designed in the form of multiple foldable panels, and the foldable panels can be unfolded in stages to cover a wider area than the vehicle as needed. The fire extinguishing fluid collection module can be folded and stored in close contact with the second housing (120), thereby minimizing the volume during the movement and storage of the device. It can be expanded and contracted automatically or manually as needed, and in the case of the automatic method, it can have a structure that unfolds or folds according to the control command of the control module (700).

[0094] In various embodiments, the fire extinguishing fluid spray module (200) can spray fire extinguishing fluid in the direction of the lower part of the vehicle. To this end, the fire extinguishing fluid spray module (200) may include a pressure pump (210), a spray pipe (220), a fire extinguishing fluid spray nozzle (230), and a nozzle fixing module (240), as shown in FIG. 3.

[0095] In various embodiments, one side of the pressure pump (210) is connected to the fire extinguishing liquid storage tank (111) and the other side is connected to the spray pipe (220), so that it can receive fire extinguishing liquid from the fire extinguishing liquid storage tank (111) and provide pressure to spray the fire extinguishing liquid toward the lower part of the vehicle.

[0096] Additionally, the pressure pump (210) can be operated to control the injection intensity and direction by command of the control module (700).

[0097] In various embodiments, the spray pipe (220) is a passage through which fire extinguishing liquid passes, one side of which is connected to a spray nozzle (230), and the other side of which is connected to a fire extinguishing liquid storage tank (111) through a pressure pump (210) included in the first housing (110) so as to supply the fire extinguishing liquid stored in the fire extinguishing liquid storage tank (111) to the spray nozzle (230).

[0098] The injection pipe (220) may be composed of one or multiple pipes depending on the number of injection nozzles (230). When the injection pipe (220) is composed of multiple pipes, it consists of one main pipe and multiple sub-pipes, and the multiple sub-pipes may be connected in a structure that branches out from one main pipe.

[0099] Additionally, the injection pipe (220) is made of a material resistant to high heat and high pressure, but if the second housing (120) has a foldable structure, it can be made of a flexible material.

[0100] In various embodiments, the spray nozzle (230) is provided within the second housing (120) and connected to the spray pipe (220), so as to spray the fire extinguishing liquid supplied through the spray pipe (220) toward the upper direction of the second housing (120) (in the lower direction of the vehicle).

[0101] In various embodiments, the spray nozzle (230) may include a penetration structure to more effectively deliver extinguishing liquid to the underside of the vehicle in the event of a fire. This penetration structure may be formed at the tip of the spray nozzle (230) and may be designed to penetrate a protective panel, battery case, or other sealed structure on the underside of the vehicle.

[0102] More specifically, the penetration structure can be designed to directly spray extinguishing liquid by forcefully penetrating solid structures, such as protective panels or battery cases on the underside of the vehicle, from the bottom in the event of a fire. To this end, the nozzle fixing module (240) may include a structure that can extend vertically in length using a hydraulic cylinder or a compression spring system. When the underside of the vehicle is penetrated by a certain level of force, the spray nozzle (230) sprays extinguishing liquid directly at the point of fire, thereby increasing the efficiency of vehicle fire suppression.

[0103] In various embodiments, the nozzle fixing module (240) is provided in at least a part of the fire extinguishing liquid recovery space (121) and can fix the spray nozzle (230). At this time, if the spray nozzle (230) is fixed in close contact with the bottom surface of the fire extinguishing liquid recovery space (121), the spray nozzle (230) may be submerged by the fire extinguishing liquid recovered in the fire extinguishing liquid recovery space (121), and thus the fire extinguishing liquid may not be sprayed smoothly. Therefore, the nozzle fixing module (240) can fix the spray nozzle (230) so that it is spaced a predetermined distance from the bottom surface of the fire extinguishing liquid recovery space (121).

[0104] In various embodiments, the digestion fluid recovery module (300) can recover the digestion fluid recovered in the digestion fluid recovery space (121).

[0105] In various embodiments, the filter (310) is a device for filtering foreign substances contained in the digestion liquid collected in the digestion liquid recovery space, and may be placed between the digestion liquid recovery space (121) and the recovery pump (320) so that foreign substances contained in the digestion liquid recovered in the digestion liquid recovery space (121) can be filtered and recovered through the recovery pump (320). The digestion liquid collected in the digestion liquid recovery space (121) may move to the filter (310) due to the structural features of the digestion liquid recovery space (121) (e.g., inclined structure, unit recovery space structure with different depths, etc.), and the filter (310) can filter the digestion liquid, thereby allowing the digestion liquid from which foreign substances have been filtered to move to the recovery pump (320).

[0106] Here, the filter (310) is designed with a structure that is easy to separate and replace, thereby increasing the continuous operability of the device.

[0107] Additionally, the filter (310) may have the degree and speed of filtering adjusted by the command of the control module (700), but is not limited thereto.

[0108] In various embodiments, one side of the recovery pump (320) is connected to the recovery pipe (330) and the other side is connected to the filter (310), so that it can suck in the fire extinguishing liquid from which foreign substances have been filtered through the filter (310) and deliver it to the recovery pipe (330). The recovery pump (320) can apply pressure to the sucked fire extinguishing liquid and move it through the recovery pipe (330) to the fire extinguishing liquid storage tank (111) located inside the first housing (110).

[0109] Here, the recovery pump (320) may be operated at a strength by a command from the control module (700), but is not limited thereto.

[0110] In various embodiments, the recovery pipe (330) is a passage through which the filtered extinguishing liquid is transported to the first housing (110), with one end connected to the recovery pump (320) and the other end connected to the extinguishing liquid storage tank (111).

[0114] The fireproof window (410) may be made of a material that can withstand vehicle fire (e.g., alumina ceramic, carbon fiber composite, stainless steel, etc.) to perform the function of protecting the user from heat or flame, but is not limited thereto.

[0115] In various embodiments, the viewing window (420) may be made of a transparent and heat-resistant material so that the user can visually check the external situation.

[0116] In various embodiments, the fire hinge (430) is a device connecting the first housing (110) and the fire window module (400), allowing the fire window module (400) to be opened and closed in the up and down direction.

[0117] In various embodiments, the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid can receive and spray the fire extinguishing liquid from the outside. To this end, the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid may further include an external fire extinguishing liquid supply module (500).

[0118] In various embodiments, the external fire extinguishing fluid supply module (500) may include an external fire extinguishing fluid injection pipe (510) and a check valve (520).

[0119] In various embodiments, the external fire extinguishing liquid injection pipe (510) is connected at one end to the external fire extinguishing liquid supply device (530) and at the other end to the spray pipe (220) and / or the recovery pipe (330), so that the fire extinguishing liquid supplied from the external fire extinguishing liquid supply device (530) can be supplied to the spray nozzle (230) or transported to the fire extinguishing liquid storage tank (111) for storage.

[0120] In various embodiments, the check valve (520) is positioned between the external fire extinguishing fluid injection pipe (510) and the external fire extinguishing fluid supply device (530), and can control the flow of fire extinguishing fluid supplied from the external fire extinguishing fluid supply device (530) to prevent the fire extinguishing fluid from flowing back toward the external fire extinguishing fluid supply device (530).

[0121] In various embodiments, the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid may have a movable structure. To this end, in various embodiments, the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid may include a means of movement (600).

[0122] In various embodiments, the means of movement (600) may be formed at the bottom of the second housing (120). Here, the means of movement (600) may be driven manually or electrically, and in the case of manual operation, it may be implemented in various forms such as wheels, crawler tracks, or sliding rails. If the means of movement (600) is electrically operated, it may be linked with the control module (700) to enable remote operation or automatic movement. If the means of movement (600) is driven manually, it may be moved according to an external force applied by a user. To this end, at least a part of the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid (e.g., the rear side of the first housing (110)) may further include a handle portion (112), and the user may move the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid to a desired position by grasping the handle portion (112) and applying an external force to the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid.

[0123] In various embodiments, the control module (700) can control the operation of components included in the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid (e.g., fire extinguishing liquid spraying module (200), fire extinguishing liquid recovery module (300), means of transport (600), etc.).

[0124] For example, as shown in FIG. 15, the control module (700) obtains user input instructing a specific action from the user (e.g., the spray intensity, direction, etc. of the fire extinguishing liquid sprayed through the fire extinguishing liquid spray module (200)), generates a control command to control the operation of the components included in the vehicle fire suppression device (1000) that can reuse the fire extinguishing liquid based on the user input, and can control the operation of each component according to the generated control command.

[0125] Here, user input may be obtained through a control interface provided in at least a part of the first housing (110) (e.g., a control screen provided through a user interface (UI) output through a display unit (800) described later) or obtained through a user interface (UI) provided to a user terminal (e.g., a smartphone, tablet, laptop, etc.) (e.g., a touch input selecting a button corresponding to a specific action, etc.), but is not limited thereto.

[0126] As another example, the control module (700) acquires sensor data through a sensor (900) provided in at least a part of the fire suppression device (1000) capable of reusing fire extinguishing liquid, as shown in FIG. 15, and generates a control command to automatically control the operation of the components included in the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid based on the results of analyzing the sensor data, and can control the operation of each component according to the generated control command.

[0127] For example, the control module (700) can determine the scale of a fire that has occurred in a vehicle by analyzing sensor data, determine the spray intensity and amount of fire extinguishing liquid sprayed through the fire extinguishing liquid spray module (200) according to the scale of the fire, and control the operation of the fire extinguishing liquid spray module (200) by determining a control command corresponding to the determined spray intensity and amount.

[0128] Additionally, the control module (700) can analyze sensor data to determine the attributes of the vehicle (e.g., type of vehicle) and generate control commands based on the determined attributes. That is, the control module (700) can automatically determine the situation and control the operation of each component without user intervention.

[0129] In various embodiments, the display unit (800) may be provided in at least a part of the first housing (110) and may provide various information related to the vehicle and fire.

Hereinafter, with reference to FIGS. 16 and 17, a method for suppressing a vehicle fire using the vehicle fire suppression device capable of reusing fire extinguishing liquid will be described.

[0135]

[0136] FIG. 16 is a diagram illustrating, in various embodiments of the present disclosure, an exemplary method of operation of a fire extinguishing fluid spray module of a vehicle fire suppression device (1000) capable of reusing fire extinguishing fluid.

[0137] Referring to FIG. 16, in step S100, as a fire occurs in the vehicle, a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid is placed in the fire vehicle.

[0138] For example, in the event that a fire occurs in a vehicle, a user who wishes to use the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid can place the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid in the vehicle where the fire occurred by moving it by pushing it directly.

[0139] As another example, a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid can be moved and deployed to a vehicle where a fire has occurred, according to user input obtained through a user interface (UI) output to a user terminal or a control interface included in the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid.

[0140] Here, the fact that a vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid is placed in a fire vehicle may mean that a second housing (120) included in the vehicle fire suppression device (1000) capable of reusing fire extinguishing liquid is inserted into the lower part of the fire vehicle.

[0141] In step S110, after the vehicle fire suppression device (1000) capable of reusing the fire extinguishing liquid is deployed in the fire vehicle through step S100, control commands (e.g., spray intensity, spray direction, and spray amount of the fire extinguishing liquid) for the fire extinguishing liquid spray module (200) are generated.

[0142] In various embodiments, the control module (700) can obtain user input corresponding to detailed operating conditions for the fire extinguishing liquid injection module (200) from a user through a user interface (UI) output through a display unit (800) and / or a user interface (UI) output to a user terminal, and can generate a control command for the fire extinguishing liquid injection module (200) according to the user input obtained from the user.

[0143] In various embodiments, the control module (700) can acquire sensor data through a sensor (900) provided in at least a part of the fire suppression device and analyze the sensor data to generate a control command for the fire extinguishing liquid spray module (200).

[0144] For example, the control module (700) can analyze sensor data to determine the scale of the fire that has occurred in the vehicle and generate a control command for the fire extinguishing liquid spray module (200) according to the scale of the fire.

[0145] As another example, the control module (700) can analyze sensor data to determine the attributes of the vehicle (e.g., type of vehicle) and generate a control command for the fire extinguishing fluid injection module (200) according to the determined attributes.

[0146] In step S120, fire extinguishing liquid is sprayed onto the fire vehicle through the fire extinguishing liquid spray module (200) according to the control command generated through the control module (700) via step S110.

[0147] In various embodiments, the fire extinguishing liquid injection module (200) can obtain a control command from the control module (700), and can determine the fire extinguishing liquid injection intensity and direction, etc. according to the control command obtained from the control module (700), and can spray the fire extinguishing liquid in the direction of the vehicle's lower side by controlling the operation of the components included in the fire extinguishing liquid injection module (200) (e.g., pressure pump (210), injection pipe (220), injection nozzle (230)) according to the determined content.

[0148]

[0149] FIG. 17 is a diagram illustrating, in various embodiments of the present disclosure, an exemplary method of operation of a fire extinguishing fluid recovery module of a vehicle fire suppression device (1000) capable of reusing fire extinguishing fluid.

[0150] Referring to FIG. 17, in step S200, the fire extinguishing liquid sprayed into the vehicle through the fire extinguishing liquid spray module (200) is collected in the fire extinguishing liquid recovery space (121).

[0151] For example, when fire extinguishing liquid is sprayed onto a fire vehicle through a fire extinguishing liquid spraying module (200), the fire extinguishing liquid sprayed onto the fire vehicle may fall into a fire extinguishing liquid recovery space (121) by gravity and be collected in the fire extinguishing liquid recovery space (121).

[0152] At this time, the digestion liquid recovery space (121) can be designed with a structure in which the bottom surface has a slope of a predetermined angle relative to the ground, and accordingly, the digestion liquid recovered in the digestion liquid recovery space (121) can be concentrated at one specific recovery point by gravity.

[0153] Alternatively, the digestion liquid recovery space (121) may be designed as a plurality of unit recovery spaces with a step difference, so that the digestion liquid flows down from a unit recovery space with a small depth to a unit recovery space with a large depth, and the digestion liquid can be concentrated at one specific recovery point.

[0154] In step S210, after the digestive fluid is collected in the digestive fluid recovery space (121) through step S200, a control command for the digestive fluid recovery module (300) is generated.

[0155] In various embodiments, the control module (700) can obtain user input corresponding to detailed operating conditions for the digestive fluid recovery module (300) from a user through a user interface (UI) output through a display unit (800) and / or a user interface (UI) output to a user terminal, and can generate a control command for the digestive fluid recovery module (300) according to the user input obtained from the user.

[0156] In various embodiments, the control module (700) can acquire sensor data through a sensor (900) provided in at least a part of the fire suppression device and analyze the sensor data to generate a control command for the fire extinguishing liquid recovery module (300).

[0157] For example, the control module (700) can acquire sensor data through a sensor (900) provided in at least a part of the fire suppression device (e.g., a level sensor provided in the fire suppression liquid storage tank (111) and / or the fire suppression liquid recovery space (121), and analyze the sensor data to determine the amount of fire suppression liquid inside the fire suppression liquid storage tank (111) and the amount of fire suppression liquid in the fire suppression liquid recovery space (121), and generate a control command to control the operation of the fire suppression liquid recovery module (300) (e.g., the operation of the filter (310), recovery pump (320), recovery pipe (330), etc.) according to the remaining amount of fire suppression liquid.

[0158] In step S220, the digestive fluid recovered in the digestive fluid recovery space (121) is recovered through the digestive fluid recovery module (300) according to the control command generated through the control module (700) via step S210.

[0159] In various embodiments, the extinguishing liquid recovery module (300) can obtain a control command from the control module (700), and can determine the extinguishing liquid recovery strength, information, etc. according to the control command obtained from the control module (700), and by controlling the operation of the components included in the extinguishing liquid recovery module (300) (e.g., filter (310), recovery pump (320), recovery pipe (330)) according to the determined content, the extinguishing liquid collected in the extinguishing liquid recovery space (121) can be recovered to the extinguishing liquid storage tank (111).
