Here, when the cleaning section is provided inside the hull under the deck as in the above-described ship, it is necessary to arrange the cleaning section inside the hull and to provide a space for performing maintenance work. Providing such a space increases the structure of the bow of the ship. As the structure of the bow becomes larger, there arises a problem that the capacity of the cargo space provided on the stern side of the bow becomes correspondingly smaller.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and an object of the present invention is to provide a ship capable of expanding the cargo space.

The ship according to the present invention includes an anchor arranged outside the hull, a deck provided on the upper side of the hull, a hole penetrating the deck and the inside of the hull, and a hole connected to the anchor and passing through the hole. A ship comprising a support member for supporting an anchor on the deck and a washing section for washing the support member, wherein the washing section closest to the anchor is located on the deck. do.

Such vessels are equipped with a cleaning station for cleaning the support members that support the anchor through the bore. The wash section closest to the anchor is located on deck. Such a configuration is a configuration in which no cleaning section is provided between the deck and the anchor. If the washing section is not provided below the deck, there is no need to provide a space for arranging the washing section or performing maintenance inside the hull below the deck. Therefore, the structure of the bow of the ship can be made compact. Accordingly, the capacity of the cargo space provided on the stern side of the bow can be expanded.

The ship according to the present invention includes an anchor arranged outside the hull, a deck provided on the upper side of the hull, a hole penetrating the deck and the inside of the hull, and a hole connected to the anchor and passing through the hole. A ship comprising a support member for supporting an anchor on the deck, and a washing section for washing the support member, wherein the washing section is positioned only on the deck and the portion of the support member on the deck side is cleaned by directly ejecting liquid from the cleaning portion, and the portion of the supporting member positioned inside the hole is cleaned by flowing the liquid ejected from the cleaning portion into the hole.

Such vessels are equipped with a cleaning station for cleaning the support members that support the anchor through the bore. Washrooms are located only on deck. Such a configuration is a configuration in which no cleaning section is provided between the deck and the anchor. If the washing section is not provided below the deck, there is no need to provide a space for arranging the washing section or performing maintenance inside the hull below the deck. Therefore, the structure of the bow of the ship can be made compact. Accordingly, the capacity of the cargo space provided on the stern side of the bow can be increased. Further, the portion of the support member on the deck side is washed by directly jetting the liquid from the washing section, and the portion of the support member located in the hole is washed by the liquid jetted from the washing section. washed by flowing into the According to such a configuration, the liquid jetted from the washing section on the deck flows into the hole, so that the liquid can be prevented from splashing on the deck, and a decrease in water infiltration can be suppressed. In addition, the liquid that has flowed into the hole cleans the supporting member in the hole, so that the deterioration of the cleaning performance can be suppressed.

In a ship, a set of anchors, holes, supporting members, and cleaning units are provided on the left and right sides of the hull, and the distance between the left and right holes may be greater than the length of the holes themselves in plan view. In this way, the length of the hole can be reduced by the amount corresponding to the lack of a space for arranging the washing section under the deck. Therefore, the distance between the left and right holes can be increased with respect to the length of the holes themselves.

In the ship, a handrail may be provided around the hole on the deck, and the washing unit may be provided on the handrail. This eliminates the need to separately provide a dedicated structure for providing the cleaning section.

In the ship, the interior of the handrail may be configured as a channel for supplying liquid to the cleaning section. As a result, the handrail member can be used in common with the flow path, so that the structure around the washing section can be simplified.

In the ship, the opening may not be formed on the side surface of the hole. Since the cleaning section is provided on the deck, it is not necessary to provide an opening for providing the cleaning section on the side surface of the hole. This eliminates the need for special processing of the hole.

In the ship, the cleaning section may jet the liquid onto the supporting member from a direction substantially perpendicular to the extending direction of the supporting member. As a result, it is possible to improve the detergency at the location where the liquid is directly jetted from the cleaning part.

In the ship, a plurality of cleaning units may be provided at different positions around the support member. As a result, the supporting member can be washed from a plurality of different directions around the supporting member, so that the washing power can be improved.

Thus, according to the present invention, it is possible to provide a ship capable of expanding the cargo space.

A bow section 13 is provided on the bow side in the hull 20 , and a cargo space 3 is provided on the stern side of the bow section 13 with a bow bulkhead 14 interposed therebetween. A plurality of ballast tanks 6 for storing ballast water are provided on the cargo space 3 side of the ship 100 . A tank 7 different from the ballast tank 6 is provided on the stern side of the engine room 1 . The tank 7 may store ballast water similarly to the ballast tank 6, or may store a liquid different from the ballast water (for example, a liquid for sterilizing seawater to generate ballast water). can be Moreover, nothing is stored in the tank 7, and the job may be an empty job. A deck 10 is provided above the hull 20 . The ceiling surface of the engine room 1, the pump room 2, the cargo space 3, and the bow section 13 is composed of the deck 10, and the floor surface side, as shown in FIGS. The shell plate 11 and the inner bottom plate 12 provided inside the hull 20 of the bottom shell plate 11 form a double bottom structure. The bulkhead 4 extends in the width direction of the ship (the vertical direction in FIG. 2) and extends from the bottom shell plate 11 to the deck 10 . The bulkhead 5 extends in the width direction of the ship and extends from the inner bottom plate 12 to the deck 10 .

Cargo oil such as crude oil and refined oil transported by the vessel 100 is stored in the cargo space 3 . The cargo space 3 is divided into a total of 14 sections by dividing the inside of the hull into two sections in the width direction and seven sections in the length direction.

Next, the bow side structure of the ship 100 will be described with reference to FIGS. 3 and 4. FIG. 3 is a plan view showing the bow side of the ship, and FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIG. 3, the bow portion 13 has a shape that tapers in a mountain-like manner toward the bow side in plan view. As shown in FIG. 4 , a deck 31 is provided inside the bow section 13 at a position spaced below the deck 10 . In a region above the deck 31, the outer wall 32 of the hull 20 is slanted so as to be positioned to the outside (left side) of the hull 20 as it goes upward. In a region below the deck 31 , the outer wall 33 of the hull 20 is curved so as to protrude to the outside (left side) of the hull 20 .

As shown in FIGS. 3 and 4, the ship 100 includes an anchor 21 (see FIG. 4), a deck 10, a hose pipe 22 (hole), a chain 23 (supporting member), and a window at the bow 13. A lath 24 and a washing section 26 are provided. The anchor structure 50 consisting of the anchor 21 , the hose pipe 22 , the chain 23 , the windlass 24 , and the washing section 26 is provided in pairs on the left and right sides of the hull 20 . The left and right anchor structures 50 are provided symmetrically to each other. Here, the left anchor structure 50 will be described, but the right anchor structure 50 has the same structure as the left anchor structure 50 except that the left and right anchor structures 50 are reversed.

Anchor 21 is a weight for preventing movement of ship 100 by lowering it to the seabed when the ship is stopped. FIG. 4 shows the anchor 21 before it is lowered. In this state, the anchor 21 is arranged outside the hull 20 while being suspended from the outer wall 33 at a position spaced apart.

The hose pipe 22 is a member for forming a passage through which the chain 23 hanging the anchor 21 is passed. The hose pipe 22 penetrates the interior of the deck 10 and the hull 20 . The hose pipe 22 extends from the deck 10 to the outside of the outer wall 32 while being inclined downward toward the left (see FIG. 4). The upper end of hose pipe 22 forms an opening 36 that opens into deck 10 . The opening 36 has an elliptical shape. The lower end of the hose pipe 22 forms an opening 37 that opens outside the outer wall 32 . The outer wall 32 is formed with a tubular portion 38 that supports a portion of the hose pipe 22 protruding from the outer wall 32 . The hose pipe 22 is arranged so as to be substantially orthogonal to the outer curved surface of the outer wall 32 in plan view. Therefore, the hose pipe 22 is arranged in an inclined state so that it is positioned toward the bow as it goes leftward (see FIG. 3). The hose pipe 22 has openings 36 and 37 only at both ends in the extending direction, and does not have openings on the side surfaces in the middle. In other words, the washing section 26 is not provided in the middle of the hose pipe 22 . A side surface of the hose pipe 22 forms a continuous cylindrical surface in the extending direction.

A handrail 40 is provided on the deck 10 around the opening 36 of the hose pipe 22 . The handrail is provided so as to surround the outer side (left side) of the opening 36 in the left-right direction, and is not provided in the region through which the chain 23 passes.

Chain 23 is a member that is connected to anchor 21 and supports anchor 21 on deck 10 through hose pipe 22 . The chain 23 extends from the windlass 24 located inside (on the right side of) the opening 36 of the hose pipe 22 in the left-right direction, enters the hose pipe 22 through the opening 36 , is pulled out through the opening 37 , and is attached to the anchor 21 . (see FIG. 4). The chain 23 is arranged to extend in the same direction as the extending direction of the hose pipe 22 in plan view.

The windlass 24 is a drum-like device that raises and lowers the anchor 21 by hoisting and unwinding the chain 23 . The windlass 24 is arranged inside (on the right side) of the opening 36 of the hose pipe 22 in the left-right direction. The windlass 24 is arranged on an extension line extending in the extending direction of the hose pipe 22 in plan view. Below the deck 10 of the windlass 24 is formed an anchor chain shed 35 for storing the chains 23 within the hull 20 .

The windlass 24 is provided with a mooring drum 25 for unwinding the mooring rope. The mooring drum 25 is arranged to extend from the windlass 24 toward the stern side. The rotating shafts of the windlass 24 and the mooring drum 25 are inclined to the left as they go from the bow side to the stern side. A chain stopper 39 for adjusting the position of the chain 23 is provided between the windlass 24 and the opening 36 .

The cleaning part 26 is a member for cleaning the chain 23 . The cleaning unit 26 is composed of nozzles that clean by injecting liquid (water) onto the chain 23 . The washing section 26 is located only on the deck 10 . That is, the cleaning section 26 is not provided inside the hose pipe 22 below the deck 10 or outside the opening 37 below the hose pipe 22 . Therefore, of the washing sections 26 , the washing section 26 closest to the anchor 21 is located above the deck 10 .

The washing unit 26 jets liquid onto the chain 23 from above the deck 10 . Therefore, the part of the chain 23 on the side of the deck 10 is washed by directly jetting the liquid from the washing unit 26 . A portion of the chain 23 located inside the hose pipe 22 is washed by the liquid ejected from the washing section 26 flowing into the hose pipe 22 .

Next, with reference to FIGS. 5 and 6, the structure around the opening 36 of the hose pipe 22 will be described in detail. FIG. 5 is an enlarged view showing the configuration near the opening of the hose pipe in FIG. 6 is an enlarged view showing the configuration of the vicinity of the opening of the hose pipe in FIG. 4. FIG. As shown in FIG. 5, the opening 36 has an elliptical shape in plan view. Here, a line passing through the center point CP of the opening 36 and extending in the extending direction D1 of the hose pipe 22 and the chain 23 is defined as a reference line CL. The opening 36 draws an ellipse whose major axis is the reference line CL. The hose pipe 22 is cut along the deck 10 and does not have a portion that protrudes above the deck 10 .

As shown in FIGS. 5 and 6, the handrail 40 is constructed by combining a pillar member 41 and a horizontal member 42. As shown in FIGS. The horizontal member 42 is curved in a substantially semicircular arc shape along the elliptical opening 36 and is open at a location facing the chain restrainer 39 . A plurality of (here, three) horizontal members 42 are provided in the vertical direction. A pair of pillars 41 are provided at both ends of the horizontal member 42, a pair are provided near the center in the extending direction D1, and one is provided at the left end in the extending direction D1.

The washing unit 26 is provided on the handrail 40 . Here, the washing section 26 is provided on the lowermost cross member 42 . A pair of cleaning units 26 are arranged so as to sandwich a position near the center point CP. The jetting direction W of the cleaning unit 26 is directed toward the inner side of the hose pipe 22, that is, in a direction inclined downward with respect to the reference line CL so that the droplets do not scatter onto the deck 10 from the opening 36. . Thus, the cleaning section 26 is provided at a position slightly spaced upward from the deck 10, and the injection direction W is also inclined downward. By increasing the injection distance of the cleaning part 26 in this manner, the liquid is dispersed between the time when the liquid is ejected from the cleaning part 26 and contacts the chain 23 . As a result, since the cleaning unit 26 can spray the liquid onto the chain 23 over a wide range, even with two cleaning units 26, a sufficient cleaning power can be obtained.

As shown in FIG. 5, under the deck 10, a supply pipe 46 for supplying liquid to the washing section 26 is laid. A supply pipe 46 extends upwardly from the deck 10 at a position adjacent to the handrail 40 . The supply pipe 46 is then connected to the cross member 42 of the handrail 40 . The interior of the horizontal member 42 of the handrail 40 is configured as a flow path for supplying liquid to the cleaning section 26 . Therefore, the washing section 26 is supplied with liquid from the cross member 42 .

Next, the actions and effects of the ship 100 of this embodiment will be described.

First, a ship 300 according to a comparative example shown in FIG. 10 will be described for comparison with the ship 100 according to the present embodiment. As shown in FIG. 10 , in a ship 300 according to the comparative example, the cleaning section 26 is provided below the deck 10 , that is, inside the hull 20 . The cleaning part 26 is provided at an intermediate position of the hose pipe 22 . For this reason, it is necessary to form a space SP for arranging the washing section 26 and the piping above the hose pipe 22 in the outer wall 32 . In such a configuration, the operator had to perform maintenance such as adjustment of the mounting position of the cleaning unit 26 in the narrow space SP, which took time. In addition, since the space SP is located at a position higher than the deck 31 inside the hull 20, it is necessary to provide a working platform 310 near the space SP and a ladder 311 for accessing the platform 310. there were. Moreover, in order to form the space SP, it was necessary to increase the height H2 between the deck 10 and the hose pipe 22 . Along with this, the overall length of the hose pipe 22 in plan view (the length L1 shown in FIG. 7) is increased. Due to this influence, the windlass 24 is arranged closer to the stern side, and the collision bulkhead 14 is arranged on the stern side, which causes a problem that the volume of the cargo space 3 cannot be increased.

On the other hand, the ship 100 according to the present embodiment includes an anchor 21 arranged outside the hull 20, a deck 10 provided on the upper side of the hull 20, a hose pipe passing through the deck 10, and the inside of the hull 20. 22, a chain 23 connected to the anchor 21 and supporting the anchor 21 on the deck 10 through the hose pipe 22, and a cleaning section 26 for cleaning the chain 23. Of the washing sections 26 , the washing section 26 closest to the anchor 21 is located on the deck 10 .

Such a vessel 100 comprises a washing station 26 for washing the chain 23 supporting the anchor 21 through the hose pipe 22 . Of the washing sections 26 , the washing section 26 closest to the anchor 21 is located on the deck 10 . Such a configuration results in a configuration in which no other cleaning section 26 is provided between the deck 10 and the anchor 21 . If the cleaning section 26 is not provided below the deck 10, there is no need to provide a space (for example, space SP in FIG. 10) for arranging the cleaning section 26 and performing maintenance inside the hull 20 below the deck 10. Therefore, the structure of the bow section 13 of the ship 100 can be made compact. Accordingly, the capacity of the cargo space 3 provided on the stern side of the bow section 13 can be increased.

More specifically, for example, in the ship 300 according to the comparative example, the vertical height H2 between the deck 10 and the hose pipe 22 must be increased in order to provide the space SP in the outer wall 32 . Since the position of the portion of the outer wall 32 where the hose pipe 22 is formed is arranged on the lower side, the distance from the portion to the deck 10 is increased. This increases the length L1 (see FIG. 7) of the hose pipe 22 in plan view. Also, the distance of the opening 36 in the deck 10 of the hose pipe 22 and the outer wall 32 of the windlass 24 must be increased. Since the bow section 13 has a tapered shape toward the bow side, when the distance from the opening 36 and the outer wall 32 of the windlass 24 is large, a space for arranging the windlass 24 is secured. Secondly, the entire anchor structure 50 must be placed aft. Here, since the collision bulkhead 14 must be located at a certain distance from the anchor chain shed 35 below the windlass 24, the collision bulkhead 14 is also located at the stern side of the windlass 24. Placed on the stern side. That is, the capacity of the cargo space 3 is reduced.

On the other hand, as shown in FIG. 4, in the ship 100 of this embodiment, the space SP as shown in FIG. It constitutes the outer wall 32 . Therefore, the vertical height H1 between the deck 10 and the hose pipe 22 can be made smaller than in the comparative example. At this time, the separation distance S1 of the anchor 21 from the outer wall 33 can be made larger than the separation distance S2 (see FIG. 10) in the comparative example. Since the portion of the outer wall 32 where the hose pipe 22 is formed is arranged on the upper side, the distance from the portion to the deck 10 is shortened. As a result, the length L1 (see FIG. 7) of the hose pipe 22 in plan view is shortened. Also, the distance from the opening 36 in the deck 10 of the hose pipe 22 and the outer wall 32 of the windlass 24 can be reduced. Since the bow part 13 has a tapered shape toward the bow side, when the distance from the opening 36 and the outer wall 32 of the windlass 24 is small, the space between the left and right windlass 24 is large. , the entire anchor structure 50 can be placed on the bow side. Since the windlass 24 is arranged on the bow side, the collision bulkhead 14 can be arranged on the bow side compared to the comparative example collision bulkhead 14 (indicated by the phantom line in FIG. 7). can. That is, the capacity of the cargo space 3 can be expanded.

The arrangement of the windlass 24 will be explained in more detail with reference to FIG. FIG. 7 shows an area E through which the mooring rope pulled out from the mooring drum 25 can pass when the mooring rope is fixed to the quay. Other equipment cannot be installed in the area E, and for example, the mooring drum 25 on the right side cannot be arranged near the area E of the mooring drum 25 on the left side. In the ship 100 of this embodiment, even if the entire anchor structure 50 is arranged near the bow, the mooring drums 25 are arranged with a margin without interfering with each other. Here, by adopting the configuration of the ship 300 according to the comparative example, when the length L1 of the hose pipe 22 in plan view is increased, the left and right mooring drums 25 are arranged so as to be close to each other. As a result, they approach each other or interfere with each other. Therefore, in order to avoid the approach or interference, it is necessary to move the entire anchor structure 50 to the rudder side, and then secure a horizontal interval between the mooring drums 25 . This makes it necessary to place the collision bulkhead 14 at the position indicated by the phantom lines. If the angle θ between the reference line CL and the center line of the hull 20 is increased to compensate for the increase in the length L1, the angle of the mooring drum 25 with respect to the center line becomes smaller. The entire region E approaches the other mooring drum 25 and interferes with it. As described above, in the ship 300 according to the comparative example, the anchor structure 50 cannot be moved to the bow side as in the present embodiment. can be expanded.

In addition, in the ship 300 of the comparative example, the operator has to climb the ladder 311 and perform maintenance on the cleaning section 26 in the narrow space SP on the platform 310 at a high position. On the other hand, in the ship 100 according to the present embodiment, since all the cleaning units 26 are arranged on the deck 10, the operator can easily perform maintenance of the cleaning units 26 in a large space on the deck 10. It can be carried out. Also, in the ship 100, the ladder 311 and the platform 310 can be omitted.

A ship 100 according to the present embodiment includes an anchor 21 arranged outside a hull 20, a deck 10 provided on the upper side of the hull 20, a hose pipe 22 passing through the inside of the deck 10 and the hull 20, and an anchor. 21 and through hose pipes 22 to support the anchor 21 on the deck 10; The washing unit 26 is located only on the deck 10, and the portion of the chain 23 on the deck 10 side is washed by directly jetting the liquid from the washing unit 26, and the chain 23 is in the hose pipe 22. The portion located there is washed by the liquid ejected from the washing section 26 flowing into the hose pipe 22 .

Such a vessel 100 comprises a washing station 26 for washing the chain 23 supporting the anchor 21 through the hose pipe 22 . Wash station 26 is located only on deck 10 . Such a configuration is a configuration in which the washing section 26 is not provided between the deck 10 and the anchor 21 . If the cleaning unit 26 is not provided below the deck 10, it is not necessary to provide a space SP (see FIG. 10) for arranging the cleaning unit 26 and performing maintenance inside the hull 20 below the deck 10. Therefore, the structure of the bow section 13 of the ship 100 can be made compact. Accordingly, the capacity of the cargo space 3 provided on the stern side of the bow section 13 can be increased. The portion of the chain 23 on the side of the deck 10 is washed by directly jetting the liquid from the washing section 26, and the portion of the chain 23 positioned inside the hose pipe 22 is jetted from the washing section 26. The liquid is washed by flowing into the hose pipe 22 . According to such a configuration, the liquid jetted from the washing section 26 on the deck 10 flows into the hose pipe 22, so that the liquid can be prevented from splashing on the deck 10, and a decrease in water infiltration can be suppressed. In addition, the liquid that has flowed into the hose pipe 22 cleans the chain 23 inside the hose pipe 22, so that deterioration of cleaning performance can be suppressed.

In the ship 100, the anchors 21, the hose pipes 22, the chains 23, and the washing units 26 are provided in pairs on the left and right sides of the hull 20, and in plan view, the distance L2 between the left and right hose pipes 22 is equal to the hose pipes 22 themselves. is greater than the length L1 of (see FIG. 7). In this way, the length of the hose pipe 22 can be reduced by the amount corresponding to not providing a space for arranging the cleaning unit 26 under the deck 10 . Accordingly, the distance between the left and right hose pipes 22 can be increased with respect to the length of the hose pipes 22 themselves.

In the ship 100 , a handrail 40 is provided around the hose pipe 22 on the deck 10 , and the washing unit 26 is provided on the handrail 40 . This eliminates the need to separately provide a dedicated structure for providing the cleaning section 26 .

In the ship 100 , the inside of the handrail 40 is configured as a channel for supplying liquid to the cleaning section 26 . As a result, the horizontal member 42 of the handrail 40 can be shared with the flow path, so that the structure around the washing section 26 can be simplified.

In the ship 100, no opening is formed on the side surface of the hose pipe 22. As shown in FIG. Since the cleaning part 26 is provided on the deck 10, it is not necessary to provide an opening for providing the cleaning part 26 on the side surface of the hose pipe 22. - 特許庁As a result, special processing or the like for the hose pipe 22 can be made unnecessary.

In the ship 100 , a plurality of cleaning units 26 are provided at different positions around the chain 23 . As a result, the chain 23 can be washed from a plurality of different directions around the chain 23, so that the detergency can be improved.

The invention is not limited to the embodiments described above.

The cleaning section may be provided on the deck 10, and there is no particular limitation as to where it is provided. For example, as shown in FIGS. 8 and 9, the cleaning portion 126 may be provided on an extension portion 137 of the hose pipe 122 located above the deck 10 . In the ship 200 , a part of the upper portion of the hose pipe 122 in the circumferential direction is further extended from the deck 10 to form an extended portion 137 . Along with this, the handrail 140 has a structure that avoids the extension 137 .

The extended portion 137 is provided with cleaning portions 126 at three different positions in the circumferential direction. One cleaning unit 126 is arranged on the reference line CL in plan view. The other pair of cleaning units 126 are arranged at positions separated by a predetermined distance from the reference line CL. Also, the three cleaning units 126 are connected to branch pipes 125 for supplying liquid. A supply pipe 46 is connected to the branch pipe 125 . In ship 200 , each cleaning unit 126 jets liquid onto chain 23 from a direction substantially orthogonal to extending direction D<b>1 of chain 23 . As a result, the cleaning power can be improved at locations where the liquid is directly jetted from the cleaning section 126 .

Although the washing section was provided only in the vicinity of the opening 36 in order to suppress the splashing of the liquid, it is provided at a position spaced apart from the opening 36 instead of or in addition to this position. may be Also, the number and angles of the cleaning portions are not limited to those of the above embodiment.
