Description

Technology Field

[0001] The present invention relates to a fire extinguishing container adapted to a marine environment. Background Technology

[0002] As illustrated in FIG. 1, a container ship is a vessel that carries a number of containers (110) and performs maritime transport.

[0003] Since it is efficient for a container ship to load and transport as many containers (110) as possible, containers (110) are loaded into the cargo hold of the hull and then covered with a hatch cover, and containers are also stacked in multiple layers on top of the hatch cover.

[0004] Containers loaded on the upper side of the hatch cover are stacked in multiple layers, which raises the center of gravity and makes them highly susceptible to waves and wind. Consequently, if the hull is shaken from side to side by waves or strong winds are applied, there is a risk that the containers will detach from the hull or overturn. To prevent this, the container ship is equipped with a lashing bridge (130, see FIG. 5) to secure the containers stacked on the upper side of the hatch cover.

[0005] In a container ship, containers (110) are vertically stacked up to a height of about 25 meters from the deck, so the center of gravity is located at the top of the deck. As shown in FIG. 1 (a), external forces are repeatedly applied by waves and wind while the container ship is in operation, and as a result, the number of fire accidents involving flammable and combustible materials inside the containers is increasing.

[0006] However, since there are no regulations regarding self-contained fire suppression equipment on the upper deck of a container ship, no separate safety devices are installed. As a result, in the event of a fire, assistance from external facilities such as fire suppression vessels (120, see Fig. 1 (b)) or dedicated firefighting helicopters is required.

[0007] However, while container ships are operating on the open ocean, there was a problem in that it takes a long time to take appropriate measures against fire, raising concerns about damage to cargo and the safety of the crew, and if a fire is left unchecked, it can lead to a chain reaction that even results in the collapse of the ship.

[0008] The matters described in the technical background section of this invention are for the purpose of understanding the background of the invention and cannot be concluded as prior art already known to a person with ordinary knowledge in the field to which this technology belongs.

[0009] Korean Patent Publication No. 10-2019-0078983 The problem to be solved

[0010] The present invention is to provide a fire extinguishing container adapted to a marine environment that can minimize loss of life and property by enabling a fire extinguishing container loaded on top of freight containers loaded on a container ship to actively and rapidly extinguish a fire that has occurred in a nearby freight container.

[0011] The present invention is intended to provide a fire extinguishing container adapted to a marine environment that enables rapid fire suppression by allowing sprayed extinguishing liquid to effectively reach the fire source even in windy marine environments.

[0012] Problems to be solved other than those of the present invention will be easily understood through the following description. means of solving the problem

[0013] According to one aspect of the present invention, a fire extinguishing container is provided having a container housing having a size and shape corresponding to a cargo container, wherein the fire extinguishing liquid tank is provided in a lower region of the inner space of the container housing; and a fire extinguishing unit is received inside a concave groove formed on the upper surface of the container housing to spray fire extinguishing liquid toward a nearby fire occurrence area under the control of a control unit, wherein one or more fire extinguishing containers are disposed on the uppermost layer of the cargo containers loaded on a container ship on which cargo containers are loaded.

[0014] The fire extinguishing unit may include: a column portion having a length-extending structure that is received in the concave groove; a spray nozzle mounted on the upper end of the column portion via an angle adjuster; and a supply pump that supplies fire extinguishing liquid stored in the fire extinguishing liquid tank to the spray nozzle through a fire extinguishing liquid supply hose under the control of the control unit.

[0015] The above column portion may include a hydraulic housing with an open top, having a supply portion and a discharge portion connected to a hydraulic line so as to supply and discharge hydraulic pressure, respectively; and a lifting means coupled to the open top of the hydraulic housing so as to be able to move up and down according to the supply and discharge of hydraulic pressure, and which raises and lowers the injection nozzle coupled via the angle adjuster. Here, the injection nozzle may be positioned inside the concave groove or exposed above the concave groove by the raising or lowering of the lifting means.

[0016] The control unit may include: a receiving unit that receives fire occurrence information and wind direction / wind speed information from an environmental sensing system; an analysis unit that applies the fire occurrence information and the wind direction / wind speed information to a pre-machine-learned spraying model to generate analysis information for each fire extinguishing unit regarding the target rotation angle of the spraying nozzle, the spray hole size, and the fire extinguishing liquid spray pressure at which the fire extinguishing liquid sprayed from the spraying nozzle reaches the fire occurrence area; and a controller that, by referring to one or more of the fire occurrence information, the wind direction / wind speed information, and the analysis information, selects one or more fire extinguishing units equipped in fire extinguishing containers loaded on the container ship to spray fire extinguishing liquid to reach the fire occurrence area, and controls the operation of each selected fire extinguishing unit based on the analysis information generated by the analysis unit so that each selected fire extinguishing unit sprays fire extinguishing liquid targeting the fire occurrence area. Here, for each of the selected fire extinguishing units, the controller can control the extension and contraction of the column portion so that the spray nozzle is positioned at a height corresponding to the distance from the fire occurrence area by referring to fire occurrence information received from the environment sensing system, control the operation of the angle adjuster so that the spray nozzle is rotated by the target rotation angle and stops, and control the operation of the spray nozzle and the supply pump so that the fire extinguishing liquid is sprayed with the spray hole size and the fire extinguishing liquid spray pressure.

[0017] The above spray nozzle can be mounted on the upper part of the column at a predetermined angle of inclination so that the fire extinguishing liquid supplied through the fire extinguishing liquid supply hose is sprayed in a parabolic path to the fire occurrence area.

[0018] The fire extinguishing unit may include: a column portion that is received in the concave groove and has a length-extending structure; a spray nozzle mounted on the upper end of the column portion via a rotary drive; and a supply pump that supplies fire extinguishing liquid stored in the fire extinguishing liquid tank to the spray nozzle through a fire extinguishing liquid supply hose. Here, the rotary drive may cause the spray nozzle to rotate continuously 360 degrees with the vertical axis of the body of the column portion as the center of rotation so that the fire extinguishing liquid is sprayed widely around the surroundings.

[0019] Other aspects, features, and advantages other than those described above will become apparent from the following drawings, claims, and detailed description of the invention. Effects of the invention

[0020] According to an embodiment of the present invention, a firefighting container loaded on top of cargo containers on a container ship actively and rapidly extinguishes a fire that has occurred in a nearby cargo container, thereby minimizing loss of life and property.

[0021] In addition, even in windy marine environments, the sprayed extinguishing agent can effectively reach the fire-affected area, which also has the effect of enabling rapid fire suppression.

[0022] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below. Brief explanation of the drawing

FIG. 2 is a block diagram of a fire extinguishing system according to an embodiment of the present invention. FIGS. 3 and 4 are drawings showing the configuration and operation method of a fire extinguishing container according to embodiments of the present invention. FIG. 5 is a drawing illustrating the arrangement of fire-fighting containers in a container ship according to one embodiment of the present invention. FIG. 6 is a drawing illustrating a fire extinguishing method using a fire extinguishing container according to an embodiment of the present invention. Specific details for implementing the invention

[0024] The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0025] FIG. 2 is a block diagram of a fire extinguishing system according to one embodiment of the present invention, and FIG. 3 and FIG. 4 are diagrams showing the configuration and operation method of a fire extinguishing container according to embodiments of the present invention.

[0026] Referring to FIG. 2, the fire extinguishing system (210) includes a control unit (220) and a plurality of fire extinguishing containers (230-1, ..., 230-n, hereinafter collectively referred to as 230). The fire extinguishing containers (230) are loaded so as to be located on the top layer of the cargo containers (110) loaded on the container ship (see FIG. 5).

[0027] The control unit (220) may include a receiving unit (222), an analysis unit (223), and a controller (224).

[0028] The receiver (222) receives fire occurrence information and wind direction / wind speed information of the wind blowing on the container ship from the environment detection system (250) equipped on the container ship.

[0029] The environmental sensing system (250) provided on the container ship may include, for example, a fire detection unit, a wind direction / wind speed sensing unit, etc.

[0030] The fire detection unit may include, for example, one or more fire detectors, flame detection sensors, alarm devices, etc., which are placed at various locations on the container ship. The environment detection system (250) may generate fire occurrence information, including, for example, a fire occurrence area (i.e., location of occurrence and range of expansion) and flame temperature, by referring to information obtained from the fire detection unit, and transmit it to the fire extinguishing system (210).

[0031] Additionally, the wind direction / wind speed sensing unit may include one or more wind direction / wind speed sensors positioned at various locations on the container ship, for example. The environment sensing system (250) may generate wind direction / wind speed information, for example, of wind blowing on the container ship by referring to information obtained from the wind direction / wind speed sensing unit and transmit it to the fire extinguishing system (210).

[0032] The analysis unit (223) uses a pre-machine-learned spray model to generate analysis information regarding the target rotation angle, spray hole size, and spray pressure of the spray nozzle (330) for spraying the fire extinguishing liquid to the fire extinguishing area by the fire extinguishing unit (232) equipped in each fire extinguishing container (230) under the current wind conditions of the container ship (e.g., wind direction / wind speed information).

[0033] Here, analysis information may be generated for each of the firefighting units (232) equipped in each of the firefighting containers (230) loaded on the container ship, or may be pre-set to be generated only for the selected firefighting unit (232) among the firefighting units (232) equipped in the firefighting container (230) selected by the controller (224) to perform firefighting operations by referring to fire occurrence information as described below.

[0034] The spray model may be configured as an AI-based embedded AI module that is pre-machine-learned using learning data regarding the destination of the fire extinguishing liquid according to the target rotation angle, spray hole size, and fire extinguishing liquid spray pressure of various spray nozzles (330) under various wind conditions (i.e., wind direction and wind speed) at each time the spray nozzle (330) sprays the fire extinguishing liquid, and then generates analysis information regarding the relative position between the spray nozzle (330) and the fire occurrence area and the target rotation angle, spray hole size, and fire extinguishing liquid spray pressure of the spray nozzle (330) appropriate for the current wind conditions, in response to fire occurrence information and wind direction / wind speed information received through the receiver (222).

[0035] Here, the target rotation angle of the spray nozzle (330) may be a rotation angle such that the spray nozzle (330) is directed directly toward the fire source area when there is no wind, but when there is wind, it may be a rotation angle such that the direction of travel of the extinguishing liquid sprayed from the spray nozzle (330) is changed by the influence of the wind and consequently reaches the fire source area.

[0036] In addition, the spray hole size and the fire extinguishing liquid spray pressure can each be determined to be a size that allows the fire extinguishing liquid sprayed from the spray nozzle (330), which is rotated by a target rotation angle in both the case where there is no wind and the case where there is wind, to reach the fire occurrence area.

[0037] Training data for machine learning of the spray model may be stored in advance in a storage unit (not shown). Additionally, the spray model may be machine learned in real time during fire extinguishing operations using newly collected training data, which is continuously generated while the spray nozzle (330) of the selected fire extinguishing unit (232) sprays fire extinguishing liquid toward the fire area (e.g., information collected or generated by a fire detection unit and a wind direction / wind speed sensing unit, spray control commands for controlling the target rotation angle / spray hole size / fire extinguishing liquid spray pressure of the spray nozzle (330), etc.).

[0038] The fragmentation model may be implemented to learn by utilizing various methods, such as few-shot learning, which allows learning with only a small amount of training data, or generative models like Generative Adversarial Networks (GANs) to increase similar data and overcome the lack of training data with a small amount of training data.

[0039] The projection model may be generated using one or more deep learning-based models, such as a Fully Convolutional Neural Network, a Convolutional Neural Network, a Recurrent Neural Network, a Restricted Boltzmann Machine, or a Deep Belief Neural Network. Of course, it may also be implemented using machine learning techniques other than deep learning techniques, or generated as a hybrid model combining deep learning techniques and machine learning techniques.

[0040] In addition, the methods for training the splice model can also vary, such as supervised learning, unsupervised learning, and reinforcement learning.

[0041] The controller (224) can refer to the fire occurrence information and wind direction / wind speed information received from the environment detection system (250) through the receiver (222), select one or more fire extinguishing containers (230) to perform fire extinguishing operations and one or more fire extinguishing units (232) provided in the fire extinguishing containers (230), and control the operation of the selected fire extinguishing units (232).

[0042] Here, when selecting a fire extinguishing container (230) to perform fire extinguishing operations, as shown in FIG. 6, the controller (224) may select one or more adjacent fire extinguishing containers (230) based on information regarding the fire occurrence area included in the fire occurrence information. Additionally, the controller (224) may select a fire extinguishing unit (232) to perform fire extinguishing operations from among the fire extinguishing units (232) equipped in the selected fire extinguishing container (230) by considering whether the sprayed fire extinguishing liquid reaches the fire occurrence area by referring to wind direction / wind speed information.

[0043] At this time, if two or more fire extinguishing units (232) are provided in the fire extinguishing container (230) (see FIG. 3 and FIG. 4), the controller (224) may select all fire extinguishing units (232) provided in the fire extinguishing container (230) to perform fire extinguishing operations, but may also select only some of the provided fire extinguishing units (232) to perform fire extinguishing operations by referring to wind direction / wind speed information (see FIG. 6).

[0044] The controller (224) can control the length adjustment of the column portion (320) to a height corresponding to the relative distance between each selected fire extinguishing unit (232) and the fire occurrence area, in order to control the operation of the fire extinguishing unit (232) so that fire extinguishing work is carried out.

[0045] For example, the body length of the column portion (320) can be adjusted within a range from a maximum length to a minimum length by the control of the controller (224) so ​​that the fire extinguishing liquid sprayed from the spray nozzle (330) in a parabolic path reaches the fire occurrence area.

[0046] At this time, the controller (224) can control the body length of each column portion (320) of each of the multiple fire extinguishing units (232) provided in the fire extinguishing container (230) to be the same length, as shown in FIG. 3. Alternatively, the controller (224) can control the body length to be adjusted so that the further a fire extinguishing unit (232) is located, the longer it is, by considering the distance between each fire extinguishing unit (232) and the fire occurrence area, as shown in FIG. 4.

[0047] As shown in FIG. 4, if the body length of the fire extinguishing unit (232) located far from the fire source is adjusted to be relatively long, the fire extinguishing liquid can be effectively reached the fire source even if the extinguishing liquid is sprayed at a relatively small spray pressure because the extinguishing liquid is sprayed at a relatively high position.

[0048] Additionally, the controller (224) can control the operation of the spray nozzle (330), angle adjuster (340), and supply pump (not shown) by referring to analysis information regarding the target rotation angle, spray hole size, and fire extinguishing liquid spray pressure of the spray nozzle (310) generated using a machine-learned spray model in the analysis unit (223). Here, the supply pump can perform the operation of supplying fire extinguishing liquid stored in the fire extinguishing liquid tank (234) of the fire extinguishing container (230) to the spray nozzle (330) of the corresponding fire extinguishing unit (232) so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the relative distance between each fire extinguishing unit (232) selected by the controller (224) and the point of fire occurrence.

[0049] That is, the controller (224) can control the operation of the angle adjuster (340) of each selected fire extinguishing unit (230) by referring to the analysis information generated by the analysis unit (223) so that the spray nozzle (330) is rotated by a target rotation angle such that the fire extinguishing liquid sprayed from the spray nozzle (330) reaches the fire occurrence area (see FIG. 6).

[0050] Additionally, the controller (224) can control the operation of the supply pump that supplies the fire extinguishing liquid stored in the fire extinguishing liquid tank (234) of the fire extinguishing container (230) to the spray nozzle (330) and the spray nozzle (330) that sprays the fire extinguishing liquid, by referring to the analysis information generated by the analysis unit (223), so that the fire extinguishing liquid is sprayed at a spray pressure and spray hole size corresponding to the relative distance between each selected fire extinguishing unit (232) and the fire occurrence point and the wind direction / wind speed.

[0051] Operation control for each of the selected firefighting units (232) of the controller (224) can be pre-set to continue until firefighting completion information is received from the environment sensing system (250).

[0052] Each of the fire extinguishing containers (230) included in the fire extinguishing system (210) is equipped with one or more fire extinguishing units (232) and a fire extinguishing liquid tank (234) for storing fire extinguishing liquid to be supplied to the fire extinguishing units (232).

[0053] As illustrated in FIGS. 3 and FIGS. 4, respectively, the fire extinguishing container (230) may be equipped with one or more fire extinguishing units (232), and each fire extinguishing unit (232) may include a column portion (320), a spray nozzle (330), an angle adjuster (340), and a fire extinguishing liquid supply hose (350).

[0054] The column portion (320) has its body length adjusted in the vertical direction by the control of the controller (224), so that the position of the injection nozzle (330) is adjusted in the up and down direction.

[0055] The column portion (320) for raising and lowering the injection nozzle (330) may be, for example, a hydraulic ram device and may include a hydraulic housing (322) and a lifting means (324).

[0056] Although not illustrated, the hydraulic housing (322) may be equipped with a supply section and a discharge section connected to a hydraulic line so that the supply and discharge of hydraulic fluid are respectively controlled by the controller (224). The upper part of the hydraulic housing (322) may be formed as an opening, and a lifting means (324) may be coupled to the upper part of the hydraulic housing (322) so as to be able to move up and down in response to the supply and discharge of hydraulic fluid.

[0057] One or more concave grooves are formed on the upper surface of the container housing (310) of the fire extinguishing container (230). A hydraulic housing (322) and a lifting means (324) are accommodated inside the concave groove, and in response to the supply and discharge of hydraulic pressure under the control of the controller (224), the upper end of the lifting means (324) can be raised or lowered so as to be located inside the concave groove or exposed outside the concave groove.

[0058] Although not shown, a fire detector, flame detection sensor, etc., for detecting whether a fire has occurred in the surroundings may be installed on the upper side of the lifting means (324) as part of an environmental detection system (250).

[0059] A spray nozzle (330) is mounted on the upper part of the lifting means (324) via an angle adjuster (340). The spray nozzle (330) may be mounted on the upper part of the lifting means (324) at a predetermined angle of inclination so that the sprayed extinguishing liquid reaches the fire source along a parabolic path.

[0060] Although FIGS. 3 and 4 illustrate a case where the spray nozzle (330) is mounted on the upper side of the column (320) with the nozzle exposed to the outside, it is obvious that the spray nozzle (330) may be positioned inside the enclosure mounted on the upper side of the column (320) and operated to be exposed to the outside by the control of the controller (224) that receives fire occurrence information.

[0061] The spray nozzle (330) can be connected to the fire extinguishing liquid tank (234) via the fire extinguishing liquid supply hose (350). For example, the fire extinguishing liquid tank (234) can be placed in the lower area of ​​the inner space of the fire extinguishing container (230). For example, foam fire extinguishing liquid may be stored in the fire extinguishing liquid tank (234), and any other fire extinguishing liquid suitable for extinguishing a fire in the cargo container (110) may be stored without limitation.

[0062] A supply pump (not shown) may be further provided to supply the fire extinguishing liquid stored in the fire extinguishing liquid tank (234) to the spray nozzle (330) at a pressure indicated by the controller (224) in accordance with the analysis information generated by the analysis unit (223), so that the fire extinguishing liquid stored in the fire extinguishing liquid tank (234) is sprayed through the spray nozzle (330) and reaches the fire occurrence range.

[0063] The angle adjuster (340) rotates the spray nozzle (330) by a target rotation angle by the control of the controller (224), which is based on analysis information generated by the analysis unit (223) based on the relative position between each fire extinguishing unit (232) selected for fire extinguishing operations and the fire occurrence point and the wind direction / wind speed information, by referring to fire occurrence information and wind direction / wind speed information. The angle adjuster (340) may be configured to rotate the spray nozzle (310) horizontally, for example, with the vertical axis of the body of the column part (320) as the center of rotation.

[0064] As another example, a rotary drive that continuously rotates the spray nozzle (330) 360 degrees may be provided between the column (320) and the spray nozzle (330) instead of an angle adjuster (340).

[0065] That is, when an angle adjuster (340) is included, the fire extinguishing unit (232) equipped in the fire extinguishing container (230) can function as an angle-adjustable fire extinguishing device in which the spray nozzle (330) is rotated and fixed toward the fire occurrence area (see FIG. 6). Alternatively, when a rotary drive is included, the fire extinguishing unit (232) can function as a rotary-driven fire extinguishing device in which the spray nozzle (330) rotates continuously 360 degrees at a predetermined rotational speed with the vertical axis of the body of the lifting means (324) as the rotation center and sprays fire extinguishing liquid in all directions.

[0066] Although not shown in FIGS. 4 and 5, the spray nozzle (330) may be further connected to a seawater tank through a seawater supply hose so that either the extinguishing liquid or seawater may be selectively sprayed through the spray nozzle (330), and a seawater pump (not shown) may be further provided to supply seawater stored in the seawater tank to the spray nozzle (330) at a pressure indicated by the controller (224).

[0067] In this case, when a fire occurs in a cargo container (110), the controller (224) can control the fire to be suppressed by first using a fire extinguishing agent, and then by second using seawater. That is, the controller (224) can be configured to control the operation of the supply pump so that the fire extinguishing agent stored in the fire extinguishing agent tank (234) is sprayed into the fire-affected area through the spray nozzle (330) for first fire suppression, and to control the operation of the seawater pump so that the seawater stored in the seawater tank is sprayed into the fire-affected area through the spray nozzle (330) for second fire suppression.

[0068] FIG. 5 is a drawing illustrating the arrangement of fire-fighting containers in a container ship according to an embodiment of the present invention, and FIG. 6 is a drawing for explaining a fire extinguishing method using fire-fighting containers according to an embodiment of the present invention.

[0069] As shown in FIGS. 5 and 6, a number of cargo containers (110) are loaded on a container ship, and one or more fire extinguishing containers (230) are loaded on the top layer of the cargo containers (110).

[0070] When a fire occurs in a cargo container (110) loaded on a container ship, the control unit (220) receives fire occurrence information and wind direction / speed information from an environment detection system (250), and determines one or more fire extinguishing containers (230) to perform fire extinguishing operations by referring to information regarding the fire occurrence area and wind direction / speed information included in the received fire occurrence information.

[0071] For example, the controller (224) of the control unit (220) may select one or more fire extinguishing containers (230) that are relatively close to the location of the fire among the fire extinguishing containers (230) loaded on the top floor of the cargo containers (110). Additionally, the controller (224) may select a fire extinguishing unit (232) to perform fire extinguishing operations among the fire extinguishing units (232) equipped in the selected fire extinguishing container (230), by considering whether the sprayed fire extinguishing liquid reaches the fire occurrence area by referring to wind direction / wind speed information.

[0072] When two or more fire extinguishing units (232) are provided in a fire extinguishing container (230), the controller (224) may control all fire extinguishing units (232) provided in the selected fire extinguishing container (230) to perform fire extinguishing operations, but may also select only some of the fire extinguishing units (232) to perform fire extinguishing operations. Of course, even if a fire extinguishing unit (232) is provided in a fire extinguishing container (230) adjacent to a fire occurrence area, if the extinguishing liquid sprayed from all provided fire extinguishing units (232) cannot reach the fire occurrence area considering wind direction / wind speed information, no single fire extinguishing unit (232) may be selected.

[0073] The control unit (220) selects one or more fire extinguishing containers (230) and one or more fire extinguishing units (232) to perform fire extinguishing operations, and then controls the operation of the spray nozzle (330), angle adjuster (34), and supply pump by determining the target rotation angle, spray hole size, and spray pressure of the spray nozzle (330) so that the extinguishing liquid sprayed from the spray nozzle (330) reaches the fire occurrence area.

[0074] At this time, the body length of the column portion (320) of each selected fire extinguishing unit (232) may be adjusted to be equal to each other (see FIG. 3), or the body length may be adjusted to be relatively longer for fire extinguishing units (232) located further away, taking into account the distance between each fire extinguishing unit (232) and the fire occurrence area (see FIG. 4).

[0075] As illustrated in FIG. 6, fire extinguishing units (232) equipped in multiple fire extinguishing containers (230) placed around a cargo container (110) where a fire has occurred are controlled to perform fire suppression operations together, thereby enabling effective fire suppression.

[0076] FIG. 6 illustrates an example in which an angle adjuster (340) is interposed between the spray nozzle (330) and the column (320) of the fire extinguishing unit (232), so that the spray nozzle (330) is rotated and fixed toward the point of fire occurrence, thereby functioning as an angle-adjustable fire extinguishing device. However, as previously explained, a rotary drive that continuously rotates the spray nozzle (330) 360 degrees may be provided between the column (320) and the spray nozzle (330) of the fire extinguishing container (230).

[0077] When a rotary drive is provided, the fire extinguishing unit (232) can function as a rotary-driven fire extinguishing device in which the spray nozzle (330) rotates continuously 360 degrees at a predetermined rotational speed with the vertical axis of the body of the column part (320) as the center of rotation and sprays fire extinguishing liquid around it.

[0078] That is, when the control unit (220) detects that a fire has occurred in the cargo container (110), it selects one or more fire extinguishing containers (230) and one or more fire extinguishing units (232) equipped in the fire extinguishing containers (230) to perform fire extinguishing operations by referring to fire occurrence information and wind direction / wind speed information, controls the body length of the column portion (320) of each fire extinguishing unit (232) to be adjusted, and controls the operation of the supply pump and rotary drive to spray extinguishing liquid around the area at a predetermined spray pressure or a spray pressure corresponding to the relative distance between the fire extinguishing unit (232) and the fire occurrence area while the spray nozzle (330) is continuously rotated 360 degrees by the rotary drive.

[0079] In this way, if the fire extinguishing unit (232) is rotated continuously 360 degrees and sprays the fire extinguishing liquid, it can be sprayed over a wide area as it is scattered by the wind, so there is an advantage that a fire that has occurred over a wide area can be quickly suppressed.

[0080] As described above, the fire-fighting container adapted to the marine environment according to the present embodiment is loaded on top of the cargo containers loaded on a container ship, and is characterized by being able to quickly extinguish a fire that occurs in a nearby cargo container, thereby minimizing loss of life and property.

[0081] In addition, it has the feature of enabling rapid fire suppression by allowing the sprayed extinguishing agent to effectively reach the fire area even in windy marine environments.

[0082] Although the present invention has been described above with reference to embodiments thereof, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as described in the following claims.
