Description

{Fire extinguishing system in container ship adapted to marine environment}

The present invention relates to a fire extinguishing system for container ships.

A container ship is a ship that transports containers. As shown in FIG. 1, a container ship loads multiple containers and performs maritime transportation. For reference, in FIG. 1, reference numeral 10 denotes a deck house, 20 denotes a container, 30 denotes a foremast, 40 denotes a forecastle, 50 denotes a container in a hold, 60 denotes a container cooling duct, and 70 denotes a double hull. (double hull) and 80 represent a passageway, respectively.

Since it is efficient to load and transport as many containers (20) as possible on a container ship, the containers (20) are loaded in the cargo hold of the hull, then the hatch cover is covered, and the containers are stacked in multiple layers on the top of the hatch cover. I'm doing it.

Containers loaded on the upper side of the hatch cover are stacked in multiple layers, so their center of gravity is high and they are greatly affected by storms and wind. Accordingly, if the hull is shaken from side to side by a storm or a strong wind is applied, there is a risk that the container may deviate from the hull or capsize.

To prevent this, as shown in FIG. 2, the container ship is equipped with a lashing bridge 110 that secures the stacked containers to the top of the hatch cover.

The lashing bridge 110 may include an upper plate 112 and a vertical column 114. The upper plate 112 is a structure arranged horizontally parallel to the exposed surface of the hatch cover in the left and right width directions of the hull. It can be arranged in one or more stages, serves as a passage for workers to move for lashing, and is used to transport loaded containers ( A binding member (not shown) that firmly binds 20) may be fixed so that it does not move. The vertical column 114 is an upright structure that supports the upper plate 112 at a distance from the deck, and is disposed at regular intervals along the longitudinal direction of the upper plate 112 to support the upper plate 112 at a distance from the deck. do.

These lashing bridges are manufactured with the strength to withstand large loads transferred from containers.

In a container ship, containers 20 are vertically loaded from the deck to a height of about 25 meters, so the center of gravity is located at the top of the deck. While a container ship is in operation, external forces are repeatedly applied by waves and wind, and as a result, the number of fire accidents involving flammable and combustible substances inside the container is increasing.

However, safety devices are not installed on the deck of container ships because there are no regulations for their own fire suppression equipment. For this reason, in the event of a fire, the assistance of external equipment such as a fire extinguishing vessel or a fire-extinguishing helicopter is required. However, while a container ship is sailing on the ocean, it takes a lot of time to take appropriate measures against fire, resulting in damage to cargo and crew. There was a chain of problems with the safety of the ship and, if the fire was left unattended, it could lead to the collapse of the ship.

In addition, a mast is installed on the deck of a container ship as a navigational communication facility to determine the presence and location of other ships and various obstacles around the ship. As the height of the mast increases, it becomes easier to detect the communication frequency required for ship operation or to identify other ships by the ship's lights, so the mast is installed at a considerable height. Recently, with the trend of larger ships, the height of the mast has become higher and higher. there is.

However, masts installed high on container ships also have the problem of minimizing air draft and acting as a limitation when passing through height-restricted areas.

The matters described in the technical background section of this invention are for understanding the background of the invention, and cannot be assumed to be prior art already known to those skilled in the art in the field to which this technology belongs.

However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Figure 3 is a block diagram of a fire extinguishing system according to an embodiment of the present invention, and Figure 4 is a diagram illustrating the shape of a foremast fire extinguishing unit according to an embodiment of the present invention.

Referring to FIG. 3 , the fire extinguishing system 210 may include a receiver 211, a foremast extinguishing unit 205, and a controller 219.

The receiver 211 receives fire occurrence information and wind direction/speed information from the environmental detection system 215 installed on the container ship.

The environmental detection system 215 provided on a container ship may include, for example, a fire detection unit, a wind direction/speed sensing unit, etc.

The fire detection unit may include, for example, one or more fire detectors, flame detection sensors, alarm devices, etc. disposed at various locations on the container ship, and the environmental detection system 215 refers to the information obtained from the fire detection unit, For example, fire occurrence information including information on the location and extent of fire occurrence, flame temperature, etc. may be generated and transmitted to the fire extinguishing system 210.

In addition, the wind direction/wind speed sensing unit may include, for example, one or more wind direction/wind speed sensors placed at various locations on the container ship, and the environmental detection system 215 may refer to the information obtained from the wind direction/wind speed sensing unit to determine the example. For example, wind direction/wind speed information about the wind blowing on a container ship can be generated and transmitted to the fire extinguishing system 210.

The foremast fire extinguishing unit 205 may include a foremast section 213, an analysis section 214, and a fire extinguishing section 215.

As illustrated in FIG. 4 , the foremast portion 213 includes a body formed in a telescopic structure, for example, whose length can be expanded and contracted under the control of the controller 219. Additionally, although not shown, a driving unit may be provided to adjust the length of the body of the foremast unit 213 under control of the controller 219.

The body of the foremast part 213 is a vertical column 114 of the lashing bridge 110 (i.e., the highest lashing bridge) closest to the bow side among the lashing bridges 110 that secure the containers stacked on the upper part of the hatch cover. ) can be fixed using the upper area of .

Under the control of the controller 219, the body of the foremast part 213 is extended in length to be higher than the height of the container 20, so that it can not only function as a foremast as a navigation communication facility, but also can function as a foremast as a navigation communication facility. ) If a fire occurs, the spray nozzle 310, which sprays fire extinguishing liquid, may function as a pillar to position it higher than the container 20.

Of course, the body of the foremast unit 213 may be adjusted to be shortened to a predetermined length under the control of the controller 219 while the container ship passes through a height restriction area.

Although not shown, the upper side of the body of the foremast part 213 is a component of the environmental detection system 215, and includes a fire detector and flame detection to detect whether a fire has occurred in the surrounding area and/or the wind direction and speed of the wind. Sensors, wind direction/speed sensors, etc. may be installed.

The analysis unit 214 uses a pre-machine-learned injection model to detect fire at the injection nozzle 310 provided in each foremast unit 213 under the current wind conditions (e.g., wind direction/wind speed information) of the container ship. Determine the target rotation angle, spray hole size, and fire extinguishing liquid injection pressure of the spray nozzle 310 for spraying fire extinguishing liquid targeting the occurrence area.

The injection model is a fire extinguishing liquid sprayed according to the target rotation angle of the various spraying nozzles 310, the spray hole size, and the fire extinguishing liquid spraying pressure under various wind conditions (i.e., wind direction and wind speed) at each point when the spray nozzle 310 sprays the fire extinguishing liquid. Machine learning is performed in advance using learning data about the arrival location, and when fire occurrence information and wind direction/speed information are received through the receiver 211, the relative position of the spray nozzle 310 and the fire occurrence area and the current wind conditions are It may be configured with a built-in AI module based on artificial intelligence to generate analysis information about the target rotation angle, injection hole size, and extinguishing liquid injection pressure of the corresponding injection nozzle 310.

Here, the target rotation angle of the spray nozzle 310 may be a rotation angle that directs the spray nozzle 310 toward the fire occurrence area if the wind is not blowing, but if the wind blows, the target rotation angle of the spray nozzle 310 may be It may be a rotation angle that causes the direction of extinguishing liquid to change under the influence of the wind and eventually reach the fire occurrence area.

In addition, the spray hole size and the fire extinguishing liquid injection pressure each can be determined to be a size that allows the fire extinguishing liquid sprayed from the spray nozzle 310 rotated by the target rotation angle to reach the fire occurrence area in the case where the wind is not blowing and when the wind is blowing. .

Learning data for machine learning of the injection model may be stored in advance in a storage unit (not shown). In addition, the spray model is continuously generated while the spray nozzle 310 of the foremast fire extinguishing unit 205 sprays fire extinguishing liquid targeting the fire occurrence area (i.e., information collected or generated from the fire detection unit and the wind direction/wind speed sensing unit) Information, target rotation angle of the injection nozzle 310/injection hole size/injection control command for controlling the extinguishing liquid injection pressure, etc.) can be machine-learned in real time even during fire extinguishing work using newly collected learning data.

The injection model, for example, uses a few-shot learning method that can be trained with only a small amount of training data, or a generative model such as an adversarial generative network (GAN) on a small amount of training data to increase similar data to improve the training data. It can also be implemented to learn by utilizing various methods to resolve deficiencies.

Injection models include, for example, Fully Convolutional Neural Network, Convolutional Neural Network, Recurrent Neural Network, Restricted Boltzmann Machine, and Deep Belief Neural Network. Network) may be created as one or more deep learning-based models. Of course, it can be implemented with machine learning techniques other than deep learning techniques, or it can be created as a hybrid model that combines deep learning techniques and machine learning techniques.

Additionally, methods for learning the injection model can vary, including supervised learning, unsupervised learning, and reinforcement learning.

The fire extinguishing unit 215 of the foremast fire extinguishing unit 205 may include a spray nozzle 310, a fire extinguishing liquid tank 320, a fire extinguishing liquid supply hose 330, and an angle adjuster 340.

A spray nozzle 310 is mounted on the upper end of the body of the foremast part 213 via an angle adjuster 340. The spray nozzle 310 may be mounted at a predetermined inclination angle at the upper end of the body of the foremast unit 213 so that the sprayed fire extinguishing liquid reaches the fire occurrence area in a parabolic path. Here, the spray nozzle 310 may be configured to adjust the spray hole size under control of the controller 219.

In Figure 4, a case where the spray nozzle 310 is mounted on the upper side of the body of the foremast unit 213 in a state exposed to the outside is illustrated, but the spray nozzle 310 is mounted on the upper end of the body of the foremast unit 213. It is natural that it can be manipulated to be exposed to the outside under the control of the controller 219 that receives the fire occurrence information while placed inside the enclosure mounted on the side.

The spray nozzle 310 may be connected to the fire extinguishing liquid tank 320 through the fire extinguishing liquid supply hose 330. As an example, the fire extinguishing liquid tank 320 may be placed in the lower area of the lashing bridge 110 at the upper part of the deck. For example, foam extinguishing liquid may be stored in the extinguishing liquid tank 320, and any extinguishing liquid suitable for extinguishing a fire occurring in the container 20 may be stored without limitation.

The fire extinguishing liquid stored in the fire extinguishing liquid tank 320 is sprayed through the spray nozzle 310 and is applied to the fire extinguishing liquid tank 320 at the indicated pressure of the controller 219 based on the information generated by the analysis unit 214 so that it reaches the fire occurrence area. A supply pump (not shown) that supplies the stored fire extinguishing liquid to the spray nozzle 310 may be further provided.

The angle adjuster 340 is controlled by the controller 219 based on analysis information generated by the analysis unit 214 based on the relative position between the foremast fire extinguishing unit 205 and the fire occurrence area and wind direction/wind speed information, The spray nozzle 310 is rotated by the target rotation angle. For example, the angle adjuster 340 may be configured to horizontally rotate the spray nozzle 310 with the vertical axis of the body of the foremast unit 213 as the center of rotation.

Referring again to FIG. 3, the controller 219 refers to the fire occurrence information received from the environment detection system 215 through the receiver 211, and determines that the body length of the foremast unit 213 is the foremast fire extinguishing unit 205. ) The operation of the foremast unit 213 can be controlled so that the height matches the relative distance between the area and the fire occurrence area. For example, the body length of the foremast part 213, which is adjusted by the control of the controller 219, may be the maximum length, and the fire extinguishing liquid sprayed in a parabolic path from the spray nozzle 310 can be adjusted to reach the fire occurrence area. It may be the length of the body that makes up the height.

In addition, the controller 219 refers to the analysis information on the target rotation angle, injection hole size, and extinguishing liquid injection pressure of the injection nozzle 310 generated using the injection model machine-learned in advance by the analysis unit 214, and performs injection. The operations of the nozzle 310, angle adjuster 340, and supply pump can be controlled.

Operation control of the spray nozzle 310, etc. by the controller 219 may continue until extinguishing completion information is received from the environment detection system 215.

Although not shown in FIG. 4, the injection nozzle 310 may be connected to the seawater tank through a seawater supply hose so that fire extinguishing liquid or seawater can be selectively sprayed through the injection nozzle 310, and may be connected to the seawater tank by the controller 219. A seawater pump (not shown) that supplies seawater stored in the seawater tank to the injection nozzle 310 at a specified pressure may be further provided.

In this case, if a fire occurs in the container 20, the controller 219 can control the first fire suppression using fire extinguishing liquid and then the second fire suppression using seawater. That is, the controller 219 controls the operation of the supply pump so that the fire extinguishing liquid stored in the fire extinguishing liquid tank 320 is sprayed to the fire occurrence area through the spray nozzle 310 for primary fire suppression, and seawater is used to extinguish the secondary fire. It may be set to control the operation of the seawater pump so that seawater stored in the tank is sprayed into the fire occurrence area through the spray nozzle 310.

Figure 5 is a diagram illustrating the arrangement of a foremast fire extinguishing unit and a deck house fire extinguishing unit according to an embodiment of the present invention, and Figure 6 is a diagram illustrating a for mast fire extinguishing unit and a deck house fire extinguishing unit according to an embodiment of the present invention. This is a drawing to explain the fire extinguishing method used.

As shown in FIG. 5, a plurality of foremast fire extinguishing units 205 are installed on the lashing bridge 110 (side, highest lashing bridge) closest to the bow among the lashing bridges 110 provided on a container ship. It can be.

When a fire occurs in a container 20 loaded on a container ship, as shown in FIG. 6, each of the foremast fire extinguishing units 205 receives fire occurrence information and wind direction/speed information received from the environmental detection system 215. With reference to, the body length of the foremast part 213 is adjusted to a height that matches the relative distance between the foremast fire extinguishing unit 205 and the fire occurrence area, and the fire extinguishing liquid sprayed from the spray nozzle 310 causes the fire. The operation of the spray nozzle 310, the angle adjuster 340, and the supply pump are controlled by determining the target rotation angle of the spray nozzle 310, the spray hole size, and the fire extinguishing liquid spray pressure to reach the target area.

As shown in Figure 6, when a plurality of foremast fire extinguishing units 205 are provided on the bow side lashing bridge 110, the plurality of foremast fire extinguishing units 205 can perform operations together for fire suppression. This can make effective fire suppression possible.

At this time, since the relative positions between each formast fire extinguishing unit 205 and the fire occurrence area are different, the target rotation angle, spray hole size, and fire extinguishing liquid injection of the spray nozzle 310 to be applied to each formast fire extinguishing unit 205 Pressure may be determined differently.

Referring again to FIG. 5, one or more deck house fire extinguishing units 515 may be installed in the deck house 510 to correspond to the foremast fire extinguishing unit 205 installed on the lashing bridge 110 on the bow side.

The deck house fire extinguishing unit 510 may include a pillar portion consisting of a body that extends in length, and a fire extinguishing portion. The fire extinguishing unit is equipped with a sprayer via a rotary actuator at the upper end of the pillar, and the sprayer can be connected to a fire extinguishing fluid tank placed on the roof of the deck house through a fire extinguishing fluid supply hose.

That is, the deck house fire extinguishing unit 510 has a configuration corresponding to the foremast fire extinguishing unit 205 described above, but the foremast extinguishing unit 205, which is an angle-adjustable fire extinguishing equipment, has a spray nozzle 310 located in the fire occurrence area. While the angle adjuster 340 is provided to rotate toward and fix the deck house fire extinguishing unit 510, which is a rotation-driven fire extinguishing equipment, the sprayer rotates 360 degrees at a predetermined rotational speed with the vertical axis of the column as the center of rotation. There is a difference in that a rotary actuator is provided to spray fire extinguishing liquid (see Figure 6).

If a fire occurs on the rooftop of the deck house 10 or in the container 20 adjacent to the deck house 10, as shown in FIG. 6, each deck house fire extinguishing unit 510 is equipped with an environmental detection system 215. With reference to the fire occurrence information received from the deck house fire extinguishing unit 510 and the fire occurrence area, the body length of the pillar is adjusted to a height that matches the relative distance between the deck house fire extinguishing unit 510 and the fire occurrence area, and the sprayer is rotated 360 degrees and pre-specified spray is performed. The operation of the supply pump and the rotary driver that supplies the fire extinguishing liquid to the sprayer is controlled to spray the fire extinguishing liquid at a spray pressure corresponding to the pressure or the relative distance between the deckhouse fire extinguishing unit 510 and the fire occurrence area.

The configuration in which the deck house fire extinguishing unit 510 rotates 360 degrees and sprays fire extinguishing liquid allows quick fire suppression through distribution of the fire extinguishing liquid over a wide range when a fire breaks out on the rooftop of the deck house or adjacent to the deck. It has the advantage of promoting the safety of people in the house.

Of course, like the foremast fire extinguishing unit 205, it is natural that the deckhouse fire extinguishing unit 510 may be equipped with an angle adjuster 340 for rotating and fixing the sprayer by replacing or adding a rotation driver.

As described above, the fire extinguishing system of a container ship adapted to the maritime environment according to this embodiment includes a foremast fire extinguishing unit, which is an angle-adjustable fire extinguishing equipment, and a deck, which is a rotation-driven fire extinguishing equipment, in case a fire occurs in a loaded container. It has the characteristic of minimizing loss of life and property by actively and quickly extinguishing fires using a house fire extinguishing unit.

In addition, the height of the foremast installed on a container ship is variable so that air draft can be minimized and passage through height-restricted areas is possible.

In addition, the foremast installed as a navigation communication facility is installed based on a lashing bridge, and the foremast is used as a fire extinguishing facility, thereby reducing the construction cost of the communication facility and fire extinguishing facility.

In addition, even in windy weather, the sprayed fire extinguishing liquid can reach the fire occurrence area, making rapid fire extinguishment possible.
