Description
【発明の詳細な説明】 本発明は重量物運搬船に関する。[Detailed description of the invention] The present invention relates to a heavy goods carrier.
従来、第１図側面図に示すようなモジユールキ
ヤリア等の重量物運搬船は船尾部からモジユール
１等の重量物を荷役するため、荷役時に船尾部に
大きな重量がかゝり、異常に大きな船尾トリムと
なり、また、船尾部に集中荷重がかゝり、船体２
を破損する惧れもあるので、このような不具合を
避けるために、第２図−断面図、第３図−
断面図に示すように、船尾部の水面下の断面積
を運航中に必要な断面積以上に大きくとつて荷役
時の浮力を大きくするようにしている。 Conventionally, heavy cargo carriers such as modular carriers as shown in the side view of Figure 1 unload heavy cargo such as module 1 from the stern, so a large amount of weight is applied to the stern during cargo handling, resulting in an abnormally large stern. Due to trimming, the concentrated load is applied to the stern, and the hull 2
There is a risk of damaging the
As shown in the cross-sectional view, the cross-sectional area of the stern section below the water surface is larger than that required during operation to increase buoyancy during cargo handling.
しかしながら、このような重量物運搬船におい
ては、船尾部の断面積を運航に必要な断面積以上
に大きくすることは船体抵抗を大きくすることに
なり、推進性能を著しく劣化させることになる。 However, in such a heavy cargo carrier, increasing the cross-sectional area of the stern section beyond the cross-sectional area necessary for navigation increases the hull resistance, which significantly deteriorates the propulsion performance.
本発明はこのような事情に鑑みて提案されたも

とする。 The present invention was proposed in view of the above circumstances, and aims to provide a heavy cargo carrier with good propulsion performance, which has a wide flat loading deck extending from the stern to the bow. A relatively flat heavy cargo carrier that carries out cargo handling from the stern has a flat hull consisting of a front half of the hull having a substantially flat rectangular cross section and a rear half of the hull having a longitudinal bottom recess with an inverted concave cross section; a first door disposed at the stern of the ship, or the first door and a second door disposed on the side of the bottom recess, and an air pipe supplying compressed air to the bottom recess. It is characterized by having a system.
本発明の一実施例を図面について説明すると、
第４図はその側面図、第５図は第４図の−に
沿つた横断面図である。 An embodiment of the present invention will be explained with reference to the drawings.
FIG. 4 is a side view thereof, and FIG. 5 is a cross-sectional view taken along - in FIG. 4.

遮断扉である。 In the above figure, the same symbols as in Fig. 1 indicate the same parts as in the same figure, 9 is a catamaran stern-shaped air reservoir recessed in the stern, and 10 is an air reservoir provided above the air reservoir 9. An air supply valve 11 is for supplying compressed air into the air reservoir 9 , and an air blocking door 11 is attached to the stern end of the boat so as to be slidable in the vertical direction and closes the rear end opening of the air reservoir 9 .
このような構造において、航行中は空気遮断扉
１１は上位置に引上げられている。 In such a structure, the air blocking door 11 is pulled up to the upper position during navigation.

要な浮力を与える。 However, during cargo handling work, the air cutoff valve 1
1 lowers it to the lower position and opens the air supply valve 1.
By supplying compressed air to the air reservoir 9 through 0 and adjusting the amount of compressed air blown, the necessary buoyancy is given to the stern part.
荷役終了後は送気弁１０を閉じるとゝもに、空
気遮断扉１１を開いて空気溜め９の空気を排出す

このような重量物運搬船によれば、排水量は運
航上の必要以上に大きくすることなく、推進性能
を向上することができる。 According to such a heavy cargo carrier, the propulsion performance can be improved without increasing the displacement beyond what is necessary for operation.
