Description

本発明は、チップ船の船首形状に関する。   The present invention relates to a bow shape of a chip ship.

製紙原料となる木材チップを運ぶ専用の船であるチップ船は、積み荷となる木材チップは比重が軽いためばら積み貨物船等と比較して貨物倉の高さが高くなる。このため、チップ船の船首は、図４のように船首構造が大きな壁（海面上の高さがネック）となって風圧抵抗となるという問題があった。   A chip ship, which is a dedicated ship for carrying wood chips, which are used as papermaking raw materials, has a cargo hold that is higher than a bulk cargo ship because the weight of the wood chips used for loading is light. For this reason, the bow of the tip ship has a problem that the bow structure becomes a large wall (the height on the sea surface is a neck) as shown in FIG.

図４は、従来のチップ船の配置構造の概略を示す縦断面図であり、図４において、１００は、チップ船、１０１は、当該チップ船１００の船首、１０２は、船舶の係船のための係船機等の配置する係船スペース、１０３は、航海関係の索具、修理用工具、予備品等を格納するために使用する倉庫であるボースンストア、１０４は、荷揚げ用のシャトルコンベアを配置するシャトルコンベア室、１０５は、積み荷ホッパー、１０６は、デッキクレーン、１０７、１０７、・・・は、チップ船倉、１０８は、居住区、１０９は、機関室である。Ｌ．Ｗ．Ｌは吃水線、大矢印は船舶航行時に受ける風圧抵抗を示す。   FIG. 4 is a longitudinal sectional view schematically showing the arrangement structure of a conventional chip ship. In FIG. 4, 100 is a chip ship, 101 is the bow of the chip ship 100, and 102 is for mooring a ship. A mooring space where mooring machines and the like are arranged, 103 is a warehouse used for storing navigation-related rigging, repair tools, spare parts, etc., and 104 is a shuttle where a shuttle conveyor for unloading is arranged Conveyor room, 105 is a loading hopper, 106 is a deck crane, 107, 107,... Are chip holds, 108 is a residential area, and 109 is an engine room. L. W. L is the flood line, and the large arrow indicates the wind pressure resistance received during ship navigation.

図４に示されるように、船首が高い壁とならざるを得ない従来のチップ船にあっては、航行時に船首に強い風圧抵抗（大矢印）を受けざるを得ない。
この種の航行時における風圧抵抗を減少させる船舶装置の例としては、例えば、実開昭６０-０７５１９３号公報に開示のものが知られている。 As shown in FIG. 4, in a conventional tip ship in which the bow has to be a high wall, strong wind pressure resistance (large arrow) must be applied to the bow during navigation.
As an example of a ship device that reduces the wind pressure resistance during navigation of this type, for example, one disclosed in Japanese Utility Model Laid-Open No. 60-075193 is known.

実開昭６０-０７５１９３号公報に開示のものは、考案名称「コンテナ船用風圧抵抗減少装置」に係り、「コンテナ船航走時の風圧を低減し、その燃費の節減を図り得るコンテナ船用風圧抵抗減少装置を提供すること」を目的としており（同公報明細書第２頁１１行〜１３行参照）、「コンテナ船上の箱形物体の前方または後方に配設され、かつその上部がこのコンテナ船の進行方向に沿った流線形を形成すること」により（同公報実用新案登録請求の範囲の記載参照）、「コンテナ船の風圧抵抗の減少を図り、燃費の節減を図ることができる」という効果を有するものである（同公報明細書第５頁４行〜５行参照）。   The one disclosed in Japanese Utility Model Publication No. 60-075193 is related to the device name “Container Ship Wind Pressure Resistance Reduction Device”. “To provide a reduction device” (see the second page, lines 11 to 13 of the same publication specification), “arranged in front of or behind a box-shaped object on a container ship, and the upper part of this container ship By forming a streamline along the direction of travel of the vehicle "(see the description of the claim for registration of the utility model), the effect of" reducing the wind pressure resistance of the container ship and saving fuel consumption "is achieved. (Refer to page 5, line 4 to line 5 of the specification of the publication).

図５は、実開昭６０-０７５１９３号公報において第３図、本考案の実施例１におけるコンテナ船の側面図として示される図であり、図において、２０１は、コンテナ船、２０２はコンテナ、２０３は風圧抵抗減少装置、２０４はブリッジである（なお、符号は、先行技術であることを明らかにするために、本願出願人において、３桁に変更して説明した。）。   FIG. 5 is a diagram shown in FIG. 3 in Japanese Utility Model Laid-Open No. 60-075193 as a side view of a container ship in Example 1 of the present invention. In the figure, 201 is a container ship, 202 is a container, Is a wind pressure resistance reducing device, and 204 is a bridge (note that the reference numeral has been changed to three digits by the applicant of the present application in order to clarify that it is a prior art).

しかしながら、この先行例は、コンテナ船に対する提案であり、これをそのままチップ船には適応することができないし、また、船首構造が大きな壁として立ちはだかるチップ船に適用したとしても、その効果は限られたものとなり，充分な効果を得ることはできない。   However, this preceding example is a proposal for a container ship, which cannot be applied to a chip ship as it is, and even if it is applied to a chip ship where the bow structure stands as a large wall, its effect is limited. The effect is not sufficient.

本発明に係るチップ船の船首形状を実施するための最良の形態としての一実施例を図面に基づき詳細に説明する。   An embodiment as the best mode for carrying out the bow shape of a chip ship according to the present invention will be described in detail with reference to the drawings.

図１は、本発明に係るチップ船の船首形状を実施するための最良形態の一実施例であるチップ船の船首形状の実施例１を示すチップ船の船首形状概略を示す縦断面図である。
図１において、１は、本実施例１に係るチップ船の船首形状、２は、係船のための係船機等を配置する係船スペース、３は、ボースンストア、４、５は、係船索(図示外)を船外に張り渡すための開口部であり、その余の符号は、例えば、チップ船１００等、図５に同一の符号で示した同一の部材である。 FIG. 1 is a longitudinal cross-sectional view schematically showing the tip shape of a tip ship showing Example 1 of the tip shape of the tip ship which is an embodiment of the best mode for carrying out the bow shape of the tip ship according to the present invention. .
In FIG. 1, 1 is the bow shape of the tip ship according to the first embodiment, 2 is a mooring space in which a mooring machine and the like for mooring are arranged, 3 is a boson store, 4 and 5 are mooring lines (illustrated) An opening for extending the outside to the outside of the ship, and the other reference numerals are, for example, the chip boat 100 and the like, which are the same members shown in FIG.

本実施例１に係るチップ船の船首構造の船首形状１は、図１のチップ船の船首形状概略縦断面図に示されるように、チップ船１００の船首部先端１を船首から船尾に向かって上昇する傾斜形状としたものである。   The bow shape 1 of the tip structure of the tip ship according to the first embodiment is as shown in the bow shape schematic longitudinal cross-sectional view of the tip ship shown in FIG. 1, and the tip portion 1 of the tip ship 100 is directed from the bow toward the stern. It is an inclined shape that rises.

船首部先端１が船首から船尾方向に向かって上昇する傾斜形状としたために、従来のチップ船の船首形状に比し、前記係船スペース１０２が減少せざるを得ない。このため、従来のチップ船１００の係船スペース１０２と同等の広さを確保するために、本実施例１に係るチップ船の船首構造の船首部先端１では、当該係船スペース２を従来のチップ船船首形状１０１では前記ボースンストア１０３が配置された区画に設けて、当該係船スペース２の下部に本実施例１に係るチップ船の船首構造の船首部先端１の前記ボースンストア３を設けたチップ船の船首形状とした。すなわち、本実施例１に係るチップ船の船首構造の船首形状１は、前記船尾に向かって上昇する直線状又は途中で傾斜角が変わる傾斜形状又は流線形状の下部に係船スペース及びボースンストアの各区画を設けたものである。 Since the bow tip 1 has an inclined shape that rises in the stern direction from the bow, the mooring space 102 has to be reduced as compared with the bow shape of a conventional tip boat. Therefore, in order to ensure the width of the equivalent mooring space 102 of a conventional chip ship 100, the bow tip 1 of the bow structure of the chip ship according to the first embodiment, the mooring space 2 conventional chip ship The tip shape 101 is provided in the section where the boson store 103 is arranged, and the tip ship in which the boson store 3 is provided at the bow tip portion 1 of the bow structure of the tip ship according to the first embodiment below the mooring space 2. The bow shape. That is, the bow shape 1 of the tip structure of the tip ship according to the first embodiment is a straight line that rises toward the stern, or an inclined shape or a streamline shape whose inclination angle changes along the way. Each section is provided.

ここで、前記船首から船尾に向かって上昇する傾斜形状における傾斜角度は、航行時の風圧抵抗が軽減できる傾斜角であれば良く、また、傾斜の始点についても、前記係船スペース２の確保の点で許容できる範囲であれば、前記吃水線(L.W.L)近傍を始点としても構わない。
また、前記傾斜は、船体縦断面上の直線傾斜に限らず、途中で傾斜角が変わる傾斜形状や，船首から船尾に向かって上昇する流線形状の傾斜であっても良く、さらには、船体平断面上においても、船尾に向かって広がる傾斜形状や途中で角度が変わる傾斜形状、流線形状であってもよい。
また、図２は、本実施例１に係るチップ船の船首構造の船首形状１の前記係船スペース２の内部の平断面概略を示す図であり、図２において、符号６は、先端係船開口部、７は、前記シャトルコンベア室１０４の前面壁、太矢印曲線は、当該係船スペース２内を流れる空気の流れを示す。
図２から明らかなように、前記シャトルコンベア室１０４の前面壁７について、そのセンターライン側を前面に突出させたクサビ形状とし、さらに、前記係船開口部５についても、前記係船スペース２内での空気の停滞を軽減し、風圧低減を図るため、前記シャトルコンベア室１０４近傍に位置する船尾側開口端部とする。
なお、本実施例１に係るチップ船の船首構造の船首形状１における前記シャトルコンベア室１０４の前面壁７の突出するクサビ形状は、その前面に配置される係船スペースの係船機等の配置スペースや係船作業に影響を及ぼさない範囲で自由な奥行きで突出可能であり、また、クサビ形状は、一つの頂角を有するものに限らず複数の頂角を有するクサビ形状も可能であり、さらには、場合によっては、半円形、半楕円形、半流線形等の形状であっても良い。
このようなチップ船において船尾に向かって上昇・広がる傾斜形状の船首形状とすることにより、航行時の風圧抵抗を低減することができる。 Here, the inclination angle in the inclination shape rising from the bow toward the stern may be an inclination angle that can reduce the wind pressure resistance at the time of navigation, and also the starting point of the inclination is to secure the mooring space 2 As long as it is within an allowable range, the vicinity of the floodline (LWL) may be used as a starting point.
In addition, the inclination is not limited to a linear inclination on the longitudinal section of the hull, and may be an inclined shape in which the inclination angle changes in the middle or a streamlined inclination that rises from the bow toward the stern. Even on a flat cross section, it may be an inclined shape spreading toward the stern, an inclined shape whose angle changes along the way, or a streamline shape.
FIG. 2 is a diagram showing an outline of a plane cross section inside the mooring space 2 of the bow shape 1 of the bow structure of the tip ship according to the first embodiment. In FIG. , 7 is the front wall of the shuttle conveyor chamber 104, and the thick arrow curve indicates the flow of air flowing through the mooring space 2.
As apparent from FIG. 2, the front wall 7 of the shuttle conveyor chamber 104 has a wedge shape with its center line projecting to the front, and the mooring opening 5 is also located in the mooring space 2. In order to reduce the stagnation of air and reduce the wind pressure, the stern side opening end located in the vicinity of the shuttle conveyor chamber 104 is used.
Note that the wedge shape protruding from the front wall 7 of the shuttle conveyor chamber 104 in the bow shape 1 of the tip structure of the tip ship according to the first embodiment is the arrangement space of the mooring machine or the like of the mooring space arranged on the front surface thereof. It can protrude at a free depth as long as it does not affect mooring work, and the wedge shape is not limited to one having a single apex angle, but can also be a wedge shape having a plurality of apex angles, Depending on the case, the shape may be a semicircular shape, a semi-elliptical shape, a semi-streamline shape, or the like.
Wind tip resistance at the time of navigation can be reduced by adopting an inclined bow shape that rises and spreads toward the stern in such a chip ship.

次に、本発明に係るチップ船の船首形状を実施するための変形として、実施例２に係るチップ船の船首形状を図面に基づき詳細に説明する。
図３は、本実施例２に係るチップ船の船首形状１０の概略を示す縦断面図であり、図４は、本実施例２に係るチップ船の船首形状１０に係る前記シャトルコンベア室１０４の前面壁１４の平断面概略を示す図である。

本実施例２に係るチップ船の船首形状１０は、図３から明らかなように、従来のチップ船１００の船首先端の立ち上がり又は先端に伸びる船首先端部を欠落させて、チップ船１００の船首先端立ち上がり部分からその上部に位置する前記シャトルコンベア室１０４の前面壁１４までの部分で、従来のチップ船１００において前記ボースンストア１０３の区画を欠落させた階段形状の船首構造としたものである。そして、当該欠落区画を露出タイプの係船スペース１２とし、その下部にボースンストア１３を配置した船首形状としたものである。   As can be seen from FIG. 3, the tip shape 10 of the tip ship according to the second embodiment is such that the tip end of the tip of the tip ship 100 is omitted or the tip of the tip of the tip ship 100 is omitted. In the portion from the rising portion to the front wall 14 of the shuttle conveyor chamber 104 located at the upper portion, a stepped bow structure in which the section of the boson store 103 is omitted in the conventional chip ship 100 is formed. The missing section is an exposed type mooring space 12 and has a bow shape in which a boson store 13 is arranged below.

すなわち、欠落の先端の始点は、従来のチップ船１００の船首部の先端立ち上がりから船首部の先端に伸びる船首先端部までの任意の高さ位置、あるいは、フォアピークタンクの上部に必要とする前記ボースンストア１３の高さを確保した位置から上部を欠落始点とする。
また、本実施例２に係るチップ船の船首形状１０では、前記シャトルコンベア室１０４の前面壁１４について、そのセンターライン側を前面に突出させたクサビ形状としたものである。 That is, the start point of the missing tip is required at any height position from the leading edge rising of the bow portion of the conventional tip ship 100 to the bow tip portion extending to the tip of the bow portion, or at the upper part of the forepeak tank. The upper part is defined as the missing start point from the position where the height of the boson store 13 is secured.
Further, in the tip shape 10 of the chip ship according to the second embodiment, the front wall 14 of the shuttle conveyor chamber 104 has a wedge shape with its center line side protruding forward.

本実施例２に係るチップ船の船首形状１０では、従来のチップ船１００の先端からの立ち上がり付近又は先端に伸びる船首先端部付近を欠落させて、チップ船１００の船首先端立ち上がり部分付近からその上部に位置する前記シャトルコンベア室１０４の前面壁１４までの部分で、従来のチップ船１００において前記ボースンストア１０３の区画を欠落させた階段形状の船首構造としたが、これは、例えば、前記シャトルコンベア室１０４をさらに船尾方向に後退させて、その後退分の上部を欠落させた二段階形状あるいは三段階形状等の階段形状としても良く、それぞれの階段状の前面壁について、そのセンターライン側を前面に突出させたクサビ形状としてもよいものである。   In the tip shape 10 of the tip ship according to the second embodiment, the vicinity of the tip from the tip of the conventional tip ship 100 or the vicinity of the tip of the bow extending to the tip is omitted, and the top of the tip of the tip ship 100 is raised from the vicinity of the tip. A portion of the shuttle conveyor chamber 104 located up to the front wall 14 is a stepped bow structure in which a section of the boson store 103 is omitted in the conventional chip ship 100. The chamber 104 may be further retracted in the stern direction, and a stepped shape such as a two-step shape or a three-step shape in which the upper portion of the retracted portion is omitted may be formed. It is good also as the wedge shape made to protrude in.

また、当該突出するクサビ形状における突出の度合い(角度)は、前述する実施例１に係るチップ船の船首構造の船首形状１における前記シャトルコンベア室１０４の前面壁７と同様に、その前面に配置される係船スペースの係船機等の配置スペースや係船作業に影響を及ぼさない範囲で自由な奥行きで突出可能であり、また、クサビ形状は、一つの頂角を有するものに限らず複数の頂角を有するクサビ形状も可能であり、さらには、場合によっては、半円形、半楕円形、半流線形等の形状であっても良い。   Further, the degree of protrusion (angle) in the protruding wedge shape is arranged on the front surface of the front wall 7 of the shuttle conveyor chamber 104 in the bow shape 1 of the bow structure of the tip ship according to the first embodiment described above. The mooring space can be projected with a free depth as long as it does not affect the arrangement space of the mooring machine, etc. and mooring work, and the wedge shape is not limited to one having a single apex angle, but a plurality of apex angles A wedge shape having the shape is also possible, and in some cases, the shape may be a semicircular shape, a semielliptical shape, a semi-streamline shape, or the like.

また、本実施例２に係るチップ船の船首形状１０では、従来のチップ船１００の先端から立ち上がり付近又は先端に伸びる船首先端部付近を欠落させて、チップ船１００の船首先端立ち上がり部分付近からその上部に位置する前記シャトルコンベア室１０４の前面壁１４までの部分を欠落させた階段形状としたが、これは、その下部に配置する前記ボースンストア１３の装備品の配置や作業性に影響を及ぼさない限りは、さらに、その高さを低く又は高くすることができ、この面でも二段階、三段階の階段状船首形状とすることを妨げない。
このような船首形状とすることにより、従来のチップ船に比し、航行時の風圧抵抗を軽減することが可能となる。 Further, in the tip shape 10 of the tip ship according to the second embodiment, the vicinity of the tip of the tip ship 100 or the vicinity of the tip of the bow extending to the tip of the tip ship 100 is omitted, and the tip of the tip ship 100 is raised from the vicinity of the tip of the tip. Although the staircase shape in which the portion up to the front wall 14 of the shuttle conveyor chamber 104 located at the upper part is omitted, this has an influence on the arrangement and workability of the equipment of the boson store 13 arranged at the lower part thereof. Unless otherwise specified, the height can be further lowered or increased, and this aspect does not prevent the two-step or three-step stepped bow shape.
By adopting such a bow shape, it becomes possible to reduce the wind pressure resistance at the time of navigation as compared with the conventional tip ship.
