Description

Fire extinguishing system in container ship}

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 receiving unit 211, a foremast extinguishing unit 205, and a controller 219.

The receiving unit 211 receives fire occurrence information from the fire monitoring system 215 installed on the container ship.

The fire monitoring system 215 provided on a container ship may include, for example, a fire detector, a flame detection sensor, an alarm device, etc., and may include, for example, information on the location and extent of fire occurrence and flame temperature. Fire occurrence information can be generated and transmitted to the fire extinguishing system 210.

The foremast fire extinguishing unit 205 may include a foremast section 213 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.

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 a predetermined length under the control of the controller 219 while the container ship passes through a height restriction area.

Although not shown, a fire detector, a flame detection sensor, etc. may be installed on the upper side of the body of the foremast unit 213 as a component of the fire monitoring system 215 to detect whether a fire has occurred in the surrounding area.

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 injection 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 point in a parabolic path.

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 at a pressure indicated by the controller 219 so that it reaches the fire occurrence range. A supply pump (not shown) may be further provided.

The angle adjuster 340 directs the spray nozzle 310 toward the fire occurrence location under the control of the controller 219, which recognizes the relative position between the foremast extinguishing unit 205 and the fire occurrence point with reference to the fire occurrence information. Adjust the posture of the spray nozzle 310 so that. 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 fire monitoring 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 fire occurrence point and the fire occurrence point. 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 reaches the fire occurrence point. It may be the length of the body that makes up the height.

Additionally, the controller 219 may refer to fire occurrence information and control the operation of the angle adjuster 340 so that the spray nozzle 310 rotates toward the fire occurrence point.

In addition, the controller 219 supplies the fire extinguishing liquid stored in the fire extinguishing liquid tank 320 to the spray nozzle 310 so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the relative distance between the foremast fire extinguishing unit 205 and the fire occurrence point. The operation of the pump can be controlled.

Operation control of the fire extinguishing unit 215 of the controller 219 may continue until fire extinguishing completion information is received from the fire monitoring 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, when 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 point 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 to the fire occurrence point 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 refers to the fire occurrence information received from the fire monitoring system 215 and fires the fire. The body length of the foremast part 213 is adjusted to a height that matches the relative distance between the mast extinguishing unit 205 and the fire occurrence point, and the angle adjuster 340 is installed so that the spray nozzle 310 rotates toward the fire occurrence point. ), and controls the operation of the supply pump that supplies fire extinguishing liquid to the spray nozzle 310 so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the relative distance between the foremast fire extinguishing unit 205 and the fire occurrence point.

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.

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 deckhouse fire extinguishing unit 510 has a configuration corresponding to the foremast fire extinguishing unit 205 described above, but the foremast fire extinguishing unit 205, which is an angle-adjustable fire extinguishing equipment, has a spray nozzle 310 located at the point where the fire occurs. While it is provided with an angle adjuster 340 that rotates and fixes it toward 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 connected to the fire monitoring system 215. With reference to the fire occurrence information received from the deck house fire extinguishing unit 510 and the fire occurrence point, the body length of the column is adjusted to a height that matches the relative distance between the deckhouse fire extinguishing unit 510 and the fire occurrence point, and the sprayer is rotated 360 degrees and pre-specified spray is performed. Controls the operation of the supply pump and the rotary driver that supply the fire extinguishing liquid to the sprayer so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the pressure or the relative distance between the deck house fire extinguishing unit 510 and the fire occurrence point.

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. This is to ensure 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, when a fire occurs in a loaded container, the fire extinguishing system of a container ship according to this embodiment uses a foremast fire extinguishing unit, which is an angle-adjustable fire extinguishing equipment, and a deck house fire extinguishing unit, which is a rotation-driven fire extinguishing equipment. It has the characteristic of minimizing loss of life and property by actively and quickly extinguishing fires.

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.
