Japanese Utility Model Publication No. 58-135395

そこで本発明は、船尾部船底下面の傾斜角をかなり大きく設定しても、航行時に同船底下面に沿う水の流れを円滑に導けるようにして、そのポッドプロペラへの流入に支障を来たさないようにした推進性能向上装置付きポッドプロペラ船を提供することを課題とする。   Therefore, the present invention prevents the inflow into the pod propeller by smoothly guiding the water flow along the bottom bottom surface during navigation even if the inclination angle of the bottom bottom surface of the stern portion is set to be considerably large. It is an object of the present invention to provide a pod propeller ship with a propulsion performance improving device that is not provided.

前述の課題を解決するため、本発明の推進性能向上装置付きポッドプロペラ船は、船尾部の後部から水中へ垂下するように設けられたポッドプロペラを備えるとともに、同ポッドプロペラよりも前方の船尾部分に船体中心線に沿うスケグを備え、航行時に船尾部よりも前方のほぼ水平な船底下面に沿う水の流れを上記船尾部の傾斜した船底下面へ沿わせるように導いて上記ポッドプロペラの後端におけるプロペラへ流入させるべく、上記船尾部の傾斜した船底下面の前端部付近に、同船底下面から離隔するようにして上記スケグから両側方へ突出したフィンが設けられていることを特徴としている。   In order to solve the above-mentioned problems, a pod propeller ship with a propulsion performance improving device according to the present invention includes a pod propeller provided to hang down from the rear part of the stern part into the water, and a stern part ahead of the pod propeller. The pod propeller has a skeg along the hull center line, and guides the water flow along the bottom bottom surface, which is almost horizontal in front of the stern during navigation, to follow the bottom bottom surface of the stern inclined to the rear end of the pod propeller. In order to flow into the propeller, a fin projecting from the skeg to both sides so as to be separated from the bottom surface of the bottom of the ship is provided near the front end of the bottom surface of the bottom of the stern that is inclined.

また、本発明の推進性能向上装置付きポッドプロペラ船は、上記フィンが、上記スケグに支軸を介し回動可能に支持されて、同支軸の回転駆動により上記フィンの迎角を調整するための駆動機構が上記スケグの内部に設けられ、上記フィンの水平状態では同フィンを上記スケグの下縁よりも下方へ突出させないように上記支軸の位置が設定されていることを特徴としている。   Further, in the pod propeller ship with a propulsion performance improving device of the present invention, the fin is rotatably supported by the skeg via a support shaft, and the angle of attack of the fin is adjusted by the rotational drive of the support shaft. The driving mechanism is provided inside the skeg, and the position of the support shaft is set so that the fin does not protrude downward from the lower edge of the skeg when the fin is in a horizontal state.

さらに、本発明の推進性能向上装置付きポッドプロペラ船は、船尾部の後部から水中へ垂下するように設けられたポッドプロペラを備えるとともに、同ポッドプロペラよりも前方の船尾部分に船体中心線に沿うスケグを備え、航行時に上記スケグに沿う水の流れを上記ポッドプロペラへ流入させるべく、上記スケグの後部下端から両側方へ突出したフィンが、上記ポッドプロペラへ向けて斜め上方へ傾斜するように設けられるとともに、同フィンの下方には上記スケグが存在しないように、同スケグの後部下端縁も後方へ向けて斜め上方に切り上げられていることを特徴としている。   Furthermore, the pod propeller ship with a propulsion performance improving device of the present invention includes a pod propeller provided so as to hang down from the rear part of the stern part into the water, and is along the hull center line in the stern part ahead of the pod propeller. Provided with a skeg, and fins that protrude from the lower end of the rear part of the skeg to both sides to incline obliquely upward toward the pod propeller so that the water flow along the skeg flows into the pod propeller during navigation. In addition, the lower end edge of the rear part of the skeg is also obliquely raised upward and rearward so that the skeg does not exist below the fin.

上述の本発明の推進性能向上装置付きポッドプロペラ船では、船尾部のスケグを利用して推進性能向上用のフィンが装着されるので、同フィンのための取付け部材を特設する必要が無くなり、しかも上記フィンの装着が容易になる利点が得られるようになる。そして、バトック船型を採用した場合には、上記スケグによる船舶の保針性能と上記フィンによる推進性能の向上と相まって、バトック船型の利点が一層高められるようになる。   In the pod propeller ship with the propulsion performance improving device of the present invention described above, since the fin for propulsion performance improvement is mounted using the skate of the stern part, it is not necessary to specially install a mounting member for the fin. The advantage of facilitating the mounting of the fins can be obtained. When the buttocks are adopted, the advantages of the buttocks are further enhanced in combination with the improvement of the marine holding performance by the skeg and the propulsion performance by the fins.

また、上記フィンの迎角が上記駆動機構により調節できるので、同フィンの迎角を船速に応じて適切に調整できるようになり、これにより船舶の推進性能を常に十分に向上させることができる。そして、入渠時には上記フィンを水平に保持してスケグ下縁よりも下方へ突出させないように同フィンの支軸の位置が設定されているので、入渠作業に支障をきたさない利点も得られるようになる。   Further, since the angle of attack of the fin can be adjusted by the drive mechanism, the angle of attack of the fin can be appropriately adjusted according to the ship speed, and thereby the propulsion performance of the ship can always be sufficiently improved. . And, since the position of the support shaft of the fin is set so that the fin is held horizontally and does not protrude downward from the lower edge of the skeg when entering, so that the advantage that does not interfere with the entry operation can be obtained.

さらに、上述の本発明の推進性能向上装置付きポッドプロペラ船では、船尾部に設けられたスケグの後部下端において、航行時にスケグ前方の船底下面から同スケグへ流入してきた水の流れを案内できるように同スケグから両側方へ突出したフィンが、スケグ後方のポッドプロペラへ向けて斜め上方へ傾斜するように設けられているので、同フィンにより案内された水の流れが上記ポッドプロペラへ適切に流入するようになり、これにより推進性能の大幅な向上が期待される。そして、上記スケグによる船体の保針性能が、上記フィンの装着による旋回抵抗の増大によって高められるようになる利点も得られる。   Furthermore, in the above-described pod propeller ship with a propulsion performance improving device of the present invention, the flow of water flowing into the skeg from the bottom bottom of the seg front can be guided at the bottom lower end of the seg provided at the stern. The fins protruding from both sides of the skeg are inclined so as to incline upward toward the pod propeller behind the skeg, so that the water flow guided by the fins flows into the pod propeller appropriately. As a result, a significant improvement in propulsion performance is expected. Further, there is also an advantage that the maintenance performance of the hull by the skeg is enhanced by an increase in turning resistance due to the mounting of the fin.

このようにして、本発明の推進性能向上装置付きポッドプロペラ船によれば、船尾部船底下面の傾斜角をかなり大きく設定しても、航行時に同船底下面に沿う水の流れを円滑に導けるようにして、そのプロペラへの流入に支障を来たさないようにすることが可能になる。   Thus, according to the pod propeller ship with a propulsion performance improving device of the present invention, even when the inclination angle of the stern part bottom surface is set to be considerably large, the water flow along the bottom surface of the stern can be smoothly guided during navigation. Thus, it becomes possible to prevent the inflow to the propeller.

図１，２は本発明の実施例１としての推進性能向上装置付きポッドプロペラ船を示すもので、図１はその船体後部を示す側面図、図２は図１のＥ−Ｅ矢視部分について一部を破断して示す拡大図である。   1 and 2 show a pod propeller ship with a propulsion performance improving device as Example 1 of the present invention. FIG. 1 is a side view showing the rear part of the hull, and FIG. 2 is a view taken along the line E-E in FIG. It is an enlarged view which fractures | ruptures and shows a part.

図１に示すように、船尾部の船底下面１が船尾端へ向かって緩やかに上昇するように傾斜したバトック船型を有する船舶において、船尾部の後部から水中へ垂下するように推進装置としてのポッドプロペラ２が設けられるとともに、同ポッドプロペラ２よりも前方の船尾部分に船体中心線に沿うスケグ28が設けられている。   As shown in FIG. 1, in a ship having a buttocks hull shape so that the bottom bottom surface 1 of the stern part gently rises toward the stern end, a pod as a propulsion device is suspended from the rear part of the stern part into the water. A propeller 2 is provided, and a skeg 28 along the hull center line is provided at the stern portion ahead of the pod propeller 2.

そして、航行時に船尾部よりも前方のほぼ水平な船底下面３に沿う水の流れを船尾部の傾斜した船底下面１へ沿わせるように導いてポッドプロペラ２のプロペラ２ａへ流入させうるように、傾斜した船底下面１の前端部付近でスケグ28から両側方へ突出したフィン４が、同船底下面１から離隔するようにして設けられている。   In order to allow the water flow along the bottom bottom surface 3 that is substantially horizontal ahead of the stern during navigation to be guided along the bottom bottom 1 inclined to the stern, and to flow into the propeller 2a of the pod propeller 2, Fins 4 projecting from the skeg 28 to both sides in the vicinity of the front end portion of the inclined bottom surface 1 are provided so as to be separated from the bottom surface 1 of the bottom.

フィン４は、図２に示すように、スケグ28に支軸４ｂを介し回転可能に支持されており、フィン４の迎角を調整するための支軸４ｂの回転駆動は、スケグ28の内部の油圧式または電動式の駆動機構29により行われるようになっている。

This is performed by a hydraulic or electric drive mechanism 29.
Further, as shown in FIG. 1, the position of the support shaft 4 b is set so that the fin 4 does not protrude downward from the lower edge of the skeg 28 in the horizontal state of the fin 4.

上述の実施例１の推進性能向上装置付きポッドプロペラ船では、船尾部のスケグ28を利用して推進性能向上用のフィン４が装着されるので、同フィン４のための取付け部材を特設する必要が無くなり、しかもフィン４の装着が容易になる利点が得られるようになる。そして、スケグ28による船舶の保針性能とフィン４による推進性能の向上と相まって、バトック船型を採用した場合の利点が一層高められるようになる。   In the pod propeller ship with the propulsion performance improving device of the first embodiment described above, the fin 4 for improving the propulsion performance is mounted by using the skate 28 of the stern part, so it is necessary to specially provide an attachment member for the fin 4 In addition, there is an advantage that the fins 4 can be easily mounted. And the advantage at the time of employ | adopting a buttocks hull form comes to be further heightened with the improvement in the needle-keeping performance of the ship by the skeg 28 and the propulsion performance by the fin 4.

また、フィン４の迎角が上記駆動機構29により調節できるので、同フィン４の迎角を船速に応じて適切に調整できるようになり、これにより船舶の推進性能を常に十分に向上させることができる。そして、入渠時にはフィン４を水平に保持してスケグ28の下縁よりも下方へ突出させないように同フィン４の支軸４ｂの位置が設定されているので、入渠作業に支障をきたさない利点も得られるようになる。   Further, since the angle of attack of the fin 4 can be adjusted by the drive mechanism 29, the angle of attack of the fin 4 can be appropriately adjusted according to the ship speed, thereby always improving the propulsion performance of the ship sufficiently. Can do. Further, since the position of the support shaft 4b of the fin 4 is set so that the fin 4 is held horizontally and does not protrude downward from the lower edge of the skeg 28 at the time of entering, there is also an advantage that the entering operation is not hindered. It will be obtained.

図３は本発明の実施例２としての推進性能向上装置付きポッドプロペラ船の船体後部側面図である。
図３に示すように、本実施例２の場合も、船尾部の船底下面１が船尾端へ向かって緩やかな角度αで上昇するように傾斜したバトック船型を有する船舶において、船尾部の後部から水中へ垂下するように推進装置としてのポッドプロペラ２が設けられるとともに、同ポッドプロペラ２よりも前方の船尾部分に船体中心線に沿うスケグ28が設けられている。 FIG. 3 is a side view of the rear part of the hull of a pod propeller ship with a propulsion performance improving device as a second embodiment of the present invention.
As shown in FIG. 3, in the case of the second embodiment as well, in a ship having a buttocks hull shape so that the bottom bottom surface 1 of the stern portion rises at a gentle angle α toward the stern end, A pod propeller 2 as a propulsion device is provided so as to hang down into the water, and a skeg 28 along the hull center line is provided at the stern portion ahead of the pod propeller 2.

この実施例２では、特に、航行時におけるスケグ28に沿う水の流れをポッドプロペラ２へ積極的に導くためのフィン30が、スケグ28の後部下端から両側方へ突出するように設けられており、同フィン30はポッドプロペラ２へ向けて斜め上方へ傾斜するように配置されている。そして、フィン30の下方にはスケグ28が存在しないように、同スケグ28の後部下端縁も後方へ向けて斜め上方に切り上げられている。   In the second embodiment, in particular, fins 30 for positively guiding the flow of water along the skeg 28 during navigation to the pod propeller 2 are provided so as to protrude from the lower end of the rear part of the skeg 28 to both sides. The fin 30 is disposed so as to be inclined obliquely upward toward the pod propeller 2. The lower end edge of the rear portion of the skeg 28 is also rounded upward obliquely upward so that the skeg 28 does not exist below the fins 30.

上述の実施例２の推進性能向上装置付きポッドプロペラ船では、バトック船型の船尾部に設けられたスケグ28の後部下端において、航行時にスケグ前方の船底下面から同スケグ28へ流入した水の流れを案内できるように同スケグ28から両側方へ突出したフィン30が、スケグ後方のポッドプロペラ２へ向けて斜め上方へ傾斜するように設けられるとともに、同フィン30の下方にはスケグ28が存在しないように、同スケグ28の後部下端縁も後方へ向けて斜め上方に切り上げられているので、同フィン30により案内された水の流れがポッドプロペラ２へ適切に流入するようになり、これにより推進性能の大幅な向上が期待される。そして、スケグ28による船体の保針性能が、フィン30の装着による旋回抵抗の増大によって高められるようになる利点も得られる。   In the pod propeller ship with the propulsion performance improving device of the second embodiment described above, the flow of water that flows into the skeg 28 from the bottom bottom of the seg forward at the time of navigation at the rear lower end of the skeg 28 provided in the stern part of the buttocks type. The fins 30 protruding from both sides of the skeg 28 so as to be guided are provided so as to be inclined obliquely upward toward the pod propeller 2 behind the skeg, and the skeg 28 does not exist below the fin 30 In addition, since the rear lower edge of the rear part of the skeg 28 is also diagonally raised upward, the water flow guided by the fin 30 can flow into the pod propeller 2 appropriately, thereby improving the propulsion performance. A significant improvement is expected. In addition, there is also an advantage that the maintenance performance of the hull by the skeg 28 is enhanced by the increase in turning resistance due to the attachment of the fins 30.

このようにして、本発明の推進性能向上装置付きポッドプロペラ船によれば、船尾部船底下面の傾斜角αをかなり大きく設定しても、航行時に同船底下面に沿う水の流れを円滑に導けるようにして、そのプロペラへの流入に支障を来たさないようにすることが可能になる。   Thus, according to the pod propeller ship with the propulsion performance improving device of the present invention, even when the inclination angle α of the bottom surface of the stern part bottom is set to be considerably large, the flow of water along the bottom surface of the bottom of the stern can be smoothly guided during navigation. In this way, it is possible to prevent the flow into the propeller from being hindered.
