Description

[0001] Mobile water monitor design system and method [

The present invention relates to a mobile water monitor, and more particularly, to a system and a method for designing the dimensions of each portion of a nozzle of a mobile water monitor so that a mobile water monitor can satisfy the radiometric and radial heights determined by IMO as performance requirements in international conventions .

Ship fires can be an obstacle to ship's ability to sink expensive ships and loaded cargoes and the lives and property of passengers and crew into the sea. It can be said that there is a great deal of artificial cases caused by natural ignition and carelessness of crew due to the characteristics of cargo. Ship fire has a slight difference depending on the cargo and the place where it occurs, but the fire spreads to the entire ship in an instant and stops the ship function.

Also, because of the characteristics that can not be easily supported from the land on the sea, which is isolated from the outside, ship fires cause huge loss of life and property. In particular, ships are made of steel with a high-speed structure, and fire suppression is a very difficult and dangerous task due to the walls and floors that are spread by the flames. Especially, when pier is pierced, it spreads to other vessels and the scale of fire can be developed into a large fire like land and building fire.

The SOLAS Convention on the Safety of Life, etc., stipulates the performance and arrangement of fire extinguishing equipment in order to ensure safety against fire in ships.

However, the conventional fire extinguishing apparatus is installed in the facilities inside the hull such as an engine room, a cabin, and a cargo hold of a ship, and a fire extinguishing system for protecting a container and the like installed in the open deck area of a container ship from fire is a fire hydrant and a fire extinguishing nozzle This is the only reality.

The container ship is a ship carrying a container. As shown in Fig. 1, the place where the container is loaded is largely divided into an open deck cargo area 10 and a cargo hold 20 .

Container vessels that load more than five tiers of container in the open deck area (10) have been popularized recently due to the appearance of large container ships. Recently, 20,000 TEU container ships are planned to be loaded up to 11 tiers.

Mobile water monitors are required to be installed on vessels for the purpose of suppressing the fire by supplying digested water when fire occurs in the high-end (five or more stages) containers of such large container ships. IMO (4 sets) per container on vessels constructed on or after 1 January 2016 in accordance with the requirements of the International Convention for the Safety of Life at Sea.

However, the fire hydrants and fire extinguishing nozzles installed in the open deck area of existing container ships are intended to suppress the fire of the container loaded in the open deck area, but generally, fire extinguishing water can be supplied only to containers of 4 stages or less, It is difficult to apply to the open deck area of the recent large container ships where the container is loaded with more than 7 ~ 8 stages. Especially, it is difficult to meet the performance requirement newly redefined in the IMO international convention.

And a display unit 400 for displaying the information set in the numerical value setting unit 300 on the screen upon request of the administrator.

At this time, the information input to the input unit 100 includes the size of the ship, the height of the highest stage of the loaded container, the main operating area of the ship, and the shipboard requirements for designing the mobile water monitor.

The determining unit 200 determines a minimum and a maximum discharge flow rate of the mobile water monitor based on the discharge flow rate data set and stored for each size of the ship based on the size of the ship input through the input unit 100 A vertical emission distance determination unit 220 for determining a vertical emission distance that is preset and stored for each emission height based on the height of the top edge of the container loaded through the input unit 100, And an inlet pressure determining unit 210 for determining a pressure at a nozzle inlet that is preset and stored based on the maximum emission flow rate determined by the emission flow rate determination unit 210 and the vertical emission distance determined by the vertical emission distance determination unit 220 230).

In addition, the determination unit 200 may adjust the reference values of the discharge flow rate, the vertical emission distance, and the nozzle inlet pressure determined by applying the requirements of the ship's main operating area and ship owner, within a predetermined threshold value. In other words, if the owner requests more discharge flow rate than the discharge flow rate, or if the vertical radiation distance is higher than the mean, it is adjusted within the threshold range based on the preset reference value .

Further, the numerical value setting unit 300 sets the total diameter of the holes of the nozzle of the mobile water monitor, which is manufactured based on the discharge flow rate, the vertical emission distance, and the nozzle inlet pressure determined in the determination unit 200, And the total length of the nozzle hole and the area of each nozzle of the nozzle based on the discharge flow rate, the vertical emission distance, and the pressure at the nozzle inlet determined by the crystal unit 200.

At this time, the numerical values of the sizes of the respective parts of the nozzle, which are set by the nozzle hole length setting part 320, are the maximum width and the minimum width of the nozzle holes for jetting and spraying, An inclination angle, and an overall length of the nozzle.

As shown in FIG. 5, the member of the nozzle according to the preferred embodiment of the present invention is constructed such that the digested water supplied through the guide passage (not shown) is directly jetted or jetted outward spraying the fire extinguishing water to the outside. More specifically, the nozzle member includes an outer nozzle 131 having a spray passage 132 for spraying extinguishing water to the outside and extending in the axial direction, and an outer nozzle 131 for spraying the outer nozzle 131 And an inner nozzle 135 having an outer diameter smaller than the inner diameter of the flow path 132 and formed with a jet flow path 136 extending along the axial direction.

The outer nozzle 131 has a cylindrical shape with both open ends, and a rear end communicates with a guide passage (not shown) inside the main body 110. The outer nozzle 131 may be detachably coupled to the front end of the main body 110.

The outer diameter of the inner nozzle 135 is smaller than the inner diameter of the spray passage 132 of the outer nozzle 131 so that the outer diameter of the inner nozzle 135 and the inner diameter of the spray passage 132 . The inner nozzle 135 may be integrally formed with the outer nozzle 131 and may be detachably coupled to the main body 110 together with the outer nozzle 131. The inner nozzle 135 may be formed separately from the outer nozzle 131, Or may be detachably coupled to the main body 110 only.

When the internal nozzle 135 is configured to be detachable from the main body 110, the internal diameter of the internal nozzle 135, which has an inner diameter different from that of the jet oil path 136, depends on the jet flow rate and the pressure of the water, Can be easily replaced and used.

The front end of the inner nozzle 135 is connected to the spray passage 132 of the outer nozzle 131 so that the extinguished water sprayed through the spray passage 132 of the outer nozzle 131 can be sprayed while being scattered to the outside. And an extension 137 is formed at the front end of the inner nozzle 135 so that the outer diameter gradually increases from the rear to the front. The extinguished water flowing along the spray passage 132 of the outer nozzle 131 is diffused and sprayed while being guided radially outward by the extended portion 137 of the inner nozzle 135 at the outlet of the spray passage 132 .

The jet path 136 of the inner nozzle 135 is configured to direct the extinguishing water to the outside under a strong pressure. In this embodiment, the jet path 136 has a predetermined length L1 Diameter portion 136a having a first inner diameter D1 and an enlarged diameter portion 136b having a second inner diameter D2 than the first inner diameter at the rear of the small diameter portion 136a. Between the small diameter portion 136a and the large diameter portion 136b of the jet path 136 is formed a tapered portion 136c whose diameter increases from the front to the back.

Since the inner diameter of the small diameter portion 136a is a factor for determining the injection flow rate and pressure of the extinguishing water sprayed to the outside, it can be designed variously according to the prescribed flow rate and pressure as described above. The large diameter portion 136b is a portion connected to a guide passage (not shown) of the main body 110. The large diameter portion 136b is tightly fitted to the guide passage (not shown) of the main body 110 irrespective of the inner diameter of the small diameter portion 136a It has a size and shape that can be connected.

The amount of mist generated when the digester water is directly blown through the jet nozzle 136 of the inner nozzle 135 depends on the length L1 and the inner diameter D1 of the small diameter portion 136a and the size of the tapered portion 136c The ratio L1 / D1 between the length L1 and the inner diameter D1 of the small diameter portion 136a is set so as to minimize the mist when the fire extinguishing water is directly fed through the jet oil passage 136 4 and the angle of the tapered portion 136c is preferably 30 degrees or less.

On the other hand, the function of spraying (spraying) water through the spray passage 132 of the outer nozzle 131 and spraying (direct) the water through the jet oil passage 136 of the inner nozzle 135 is selected by the spray type setting unit . The injection type setting unit may include a knob 140 extending outwardly from a front portion of the main body 110 and adapted to be rotated by a user and a knob 140 connected to an upper end portion of the knob 140 And a valve unit (not shown) for selectively opening and closing the flow path between the nozzle member 130 and the guide passage (not shown). The valve unit (not shown) may be a known valve device such as a spool valve device disclosed in Japanese Patent Application No. 10-0751526.

The numerical value setting unit 300 determines the numerical values of the sizes of the respective nozzles based on the emission flow rate, the vertical emission distance, and the nozzle inlet pressure determined by the determination unit 200, the maximum width D2 and the minimum width D1 of the nozzle holes for jet and spray and the length and tilt angle of the guide wall and the total length L1 and L2 of the nozzle are set.
