Description

{Fire extinguishing container loaded on container ship}

The present invention relates to a fire extinguishing container loaded on a container ship.

As shown in FIG. 1, a container ship is a ship that loads multiple containers 110 and performs maritime transportation.

Since it is efficient to load and transport as many containers (110) as possible on a container ship, the containers (110) are loaded in the cargo hold of the hull, 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, container ships are equipped with a lashing bridge (130, see FIG. 5) that secures the containers stacked on top of the hatch cover.

In a container ship, containers 110 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. As shown in Figure 1 (a), external forces are repeatedly applied by waves and wind while a container ship is in operation, 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, assistance from external facilities such as a fire extinguishing control ship (120, see (b) in Figure 1) or a helicopter dedicated to firefighting is required, but while the container ship is sailing on the ocean, the assistance of external facilities is required until appropriate measures against the fire are taken. Because it takes a lot of time, there are problems that can lead to damage to cargo, safety of crew members, and even collapse of the ship if the fire is left unattended.

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.

The receiving unit 222 receives fire occurrence information from the fire monitoring system 250 installed on the container ship.

The fire monitoring system 250 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, a fire occurrence area (i.e., location of occurrence and expansion range), flame Fire occurrence information, including information about temperature, can be generated and transmitted to the fire extinguishing system 210.

The controller 224 refers to the fire occurrence information received from the fire monitoring system 250 through the receiver 222, selects one or more fire extinguishing containers 230 to perform fire extinguishing work, and selects each selected fire extinguishing container. The operation of the fire extinguishing unit 232 of 230 can be controlled.

Here, when selecting a fire extinguishing container 230 to perform fire extinguishing work, the controller 224 selects one or more fire extinguishing containers 230 adjacent to each other based on information about the fire occurrence area included in the fire occurrence information. ) can be selected (see Figure 6).

At this time, when the fire-fighting container 230 is equipped with two or more fire-fighting units 232 (see FIGS. 3 and 4), the controller 224 controls all fire-fighting units 232 provided in the fire-fighting container 230. You may choose to perform fire extinguishing operations, or you may choose to perform fire extinguishing operations on only some of the equipped fire extinguishing units 232.

In controlling the operation of the fire extinguishing unit 232 so that fire extinguishing work is carried out, the controller 224 sets the column portion 320 to a height corresponding to the relative distance between each selected fire extinguishing unit 232 and the fire occurrence area. Length adjustment can be controlled.

For example, the body length of the pillar portion 320 ranges from the maximum length to the minimum length under the control of the controller 224 so that the fire extinguishing liquid sprayed in a parabolic path from the spray nozzle 330 reaches the height of the fire occurrence area. Can be adjusted within range.

In addition, the controller 224 may refer to fire occurrence information and control the operation of the angle adjuster 340 of each selected fire extinguishing unit 232 so that the spray nozzle 330 is rotated to an attitude toward the fire occurrence area ( 6).

In addition, the controller 224 extinguishes the fire extinguishing liquid stored in the fire extinguishing liquid tank 234 of the fire extinguishing container 230 so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the relative distance between each selected fire extinguishing unit 232 and the fire occurrence point. The operation of the supply pump that supplies to the injection nozzle 330 of the unit 232 can be controlled.

As shown in FIG. 3, the controller 224 may control the body lengths of each column portion 320 of the plurality of fire extinguishing units 232 provided in the fire extinguishing container 230 to be adjusted to the same length. , as shown in FIG. 4, the controller 224 may control the body length to be adjusted to be relatively longer for the farther away the fire extinguishing unit 232 is, considering the distance between each fire extinguishing unit 232 and the fire occurrence area. there is.

As shown in FIG. 4, when the body length of the fire extinguishing unit 232 located far from the fire occurrence area is adjusted to be relatively long, the fire extinguishing liquid can be effectively reached even if it is sprayed with a relatively small spray pressure. will be.

The operation control of each of the selected fire extinguishing units 232 of the controller 224 may be preset to continue until extinguishing completion information is received from the fire monitoring system 250.

Each of the fire extinguishing containers 230 included in the fire extinguishing system 210 includes one or more fire extinguishing units 232 and a fire extinguishing liquid tank 234 that stores fire extinguishing liquid to be supplied to the fire extinguishing unit 232.

As illustrated in FIGS. 3 and 4, one or more fire extinguishing units 232 provided in the fire extinguishing container 230 include a pillar portion 320, a spray nozzle 330, an angle adjuster 340, and a fire extinguishing liquid supply. It may include a hose 350.

The body length of the pillar portion 320 is adjusted in the vertical direction under control of the controller 224, so that the position of the spray nozzle 330 is adjusted in the vertical direction.

The pillar portion 320 that elevates the spray nozzle 330 may be, for example, a hydraulic ram device and may include a hydraulic housing 322 and a lifting means 324.

Although not shown, the hydraulic housing 322 may be provided with a supply part and a discharge part connected to a hydraulic line so that hydraulic pressure is supplied and discharged under the control of the controller 224, respectively. The upper part of the hydraulic housing 322 may be formed to be open, and the elevating means 324 is coupled to the open upper part of the hydraulic housing 322 to enable it to be raised and lowered in response to the supply and discharge of hydraulic pressure.

At least one concave groove is formed on the upper surface of the container housing 310 of the fire extinguishing container 230, and the hydraulic housing 322 and the lifting means 324 are accommodated inside the concave groove, and are controlled by the controller 224. In response to the supply and discharge of hydraulic pressure, the upper end of the lifting means 324 is positioned inside the concave groove or is raised and lowered to be exposed to the outside of the concave groove.

Although not shown, a fire detector, a flame detection sensor, etc. may be installed on the upper side of the lifting means 324 as a component of the fire monitoring system 250 to detect whether a fire has occurred in the surrounding area.

A spray nozzle 330 is mounted on the upper end of the lifting means 324 via an angle adjuster 340. The spray nozzle 330 may be mounted at a predetermined inclination angle at the upper end of the lifting means 324 so that the sprayed fire extinguishing liquid reaches the fire occurrence point in a parabolic path.

3 and 4 illustrate a case in which the spray nozzle 330 is mounted on the upper end of the pillar 320 in a state exposed to the outside, but the spray nozzle 330 is mounted on the upper end of the pillar 320. It is natural that it can be manipulated to be exposed to the outside under the control of the controller 224 that receives the fire occurrence information while placed inside the enclosure.

The spray nozzle 330 may be connected to the fire extinguishing liquid tank 234 through the fire extinguishing liquid supply hose 350. As an example, the fire extinguishing liquid tank 234 may be disposed in the lower area of the inner space of the fire extinguishing container 230. For example, foam extinguishing liquid may be stored in the extinguishing liquid tank 234, and any extinguishing liquid suitable for extinguishing a fire occurring in the cargo container 110 may be stored without limitation.

The fire extinguishing liquid stored in the fire extinguishing liquid tank 234 is sprayed through the spray nozzle 330 at a pressure indicated by the controller 224 so that it reaches the fire occurrence range. A supply pump (not shown) may be further provided.

(see Figure 6). On the other hand, when the rotation driver is inserted, the fire extinguishing unit 232 rotates so that the spray nozzle 330 rotates 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. It can function as a powered fire extinguishing device.

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

In this case, if a fire occurs in the cargo container 110, the controller 224 can control the first fire suppression using fire extinguishing liquid and then the second fire suppression using seawater. That is, the controller 224 controls the operation of the supply pump so that the fire extinguishing liquid stored in the fire extinguishing liquid tank 234 is sprayed to the fire occurrence area through the spray nozzle 330 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 the seawater stored in the tank is sprayed to the fire occurrence point through the spray nozzle 330.

When a fire occurs in the cargo container 110 loaded on a container ship, the control unit 220 receives fire occurrence information from the fire monitoring system 250 and relates to the fire occurrence area included in the received fire occurrence information. With reference to the information, one or more fire extinguishing containers 230 on which fire extinguishing work will be performed are determined.

For example, the controller 224 of the control unit 220 selects one or more fire extinguishing containers 230 relatively close to the location of the fire among the fire extinguishing containers 230 loaded on the top floor of the cargo containers 110. You will be able to select .

If the fire extinguishing container 230 is equipped with two or more fire extinguishing units 232, the controller 224 may control all fire extinguishing units 232 provided in the selected fire extinguishing container 230 to perform fire extinguishing work. However, only some fire extinguishing units 232 may choose to perform fire extinguishing operations.

The control unit 220 selects one or more fire extinguishing containers 230 on which to perform fire extinguishing work, selects one or more fire extinguishing units 232 provided in the selected fire extinguishing containers 230, and then selects each selected fire extinguishing unit. The body length of the pillar portion 320 of (232) is controlled to be adjusted, the operation of the angle adjuster 340 is controlled so that the spray nozzle 330 is rotated toward the fire occurrence point, and the fire extinguishing unit 230 and the fire occurrence are controlled. The operation of the supply pump that supplies fire extinguishing liquid to the spray nozzle 330 is controlled so that the fire extinguishing liquid is sprayed at a spray pressure corresponding to the relative distance between points.

At this time, the body length of the pillar portion 320 of each selected fire extinguishing unit 232 is adjusted to be equal to each other (see FIG. 3), or is positioned far away considering the distance between each fire extinguishing unit 232 and the fire occurrence area. The body length of the fire extinguishing unit 232 can be adjusted to be relatively longer (see FIG. 4).

It may be possible.

When the rotary driver is provided, the fire extinguishing unit 232 is a rotary driven fire extinguishing system in which the spray nozzle 330 rotates 360 degrees at a predetermined rotational speed with the vertical axis of the body of the pillar portion 320 as the center of rotation and sprays fire extinguishing liquid around. It can function as equipment.

That is, when it is recognized that a fire has occurred in the cargo container 110 with reference to the fire occurrence information received from the fire monitoring system 250, the control unit 220 controls one or more fire extinguishing containers ( 230) and one or more fire extinguishing units 232 provided in the fire extinguishing container 230 are selected, the body length of the pillar portion 320 of each fire extinguishing unit 232 is controlled to be adjusted, and the spray nozzle is controlled by a rotation actuator. In a state in which (330) is rotated 360 degrees, the operation of the supply pump and the rotary driver is controlled to spray the fire extinguishing liquid to the surroundings 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. .

In this way, if the fire extinguishing unit 232 rotates 360 degrees and sprays the fire extinguishing liquid, it can be possible to spray the fire extinguishing liquid over a wide area, which has the advantage that a fire occurring in a wide area can be quickly extinguished.

As described above, the fire extinguishing container loaded on the container ship according to this embodiment is loaded on the top of the cargo containers loaded on the container ship, so that a fire occurring in a nearby cargo container can be quickly extinguished. It has the characteristic of minimizing loss of life and property.
