201233589 六、發明說明： 【發明所屬之技術領域】 本發明，是關於具有與容器成一體性之舵板的方位推 進器。 【先前技術】 先前，可使船舶朝任意方向移動，正確維持船舶現在 位置的方位推進器，如第6圖所示，是在船舶S的船尾等 安裝有容器2、螺旋槳3及舵板4。 該形態的舵板4，是由水平剖面爲舵形狀，包括有要 與船舶S連結之連結軸部的上部舵板4a，和，朝流線形2 的下方延伸具有相同之舵剖面形狀的下部舵板4b所構成 。具備有舵板4及螺旋槳3的容器2，對船舶S是成可一 體轉動。 此外，於船舶S的船內，是設有原動機5，原動機5 的動力，是經由設置在容器2內的2組圓錐齒輪單元6、 7傳達至螺旋槳3。 構成爲上述的方位推進器1，是利用設置在船體S內 未圖示的旋轉裝置使舵板4旋轉，藉此兼備可改變船舶S 航行方向之舵的功能。將方位推進器1旋轉1 8 0 ° ，是能 夠使船舶S朝後退方向航行。 爲了短時間使船舶S旋轉而以大舵角旋轉方位推進器 1時，如第6圖中從紙面右側朝左側的箭頭符號所示流動 的水流會作用在舵板4下游側（船尾側）所設置的螺旋槳 201233589 作用在該螺旋槳3的水流’是以和舵角相同的大角度 作用在螺旋槳3。因此，螺旋槳3就會旋轉在與舵角相同 大角度的斜流中導致螺旋槳3所產生之力的變動大。螺旋 槳3所產生之大的力變動，是會使方位推進器1全體振動 ，該振動會傳至船舶S及相關機器（未圖示）成爲故障的 原因。 爲了抑制如上述作用在方位推進器之力的變動，專利 文獻1中所揭示的技術是在螺旋槳之下游側的舵板，設有 長度與舵板長邊大致相等的襟翼。此外，於專利文獻2, 所揭示的技術是將舵板的形狀事先形成爲非對稱。 專利文獻3中，所揭示的技術是將1個容器設置成夾 在2片舵板之間，根據船速轉換舵角。 [先行技術文獻] [專利文獻] [專利文獻1]日本特開2004- 1 065 63號公報 [專利文獻2]日本特開2002-193189號公報 [專利文獻3]日本特開2004- 1 82096號公報 【發明內容】 [發明欲解決之課題] 但是，近年來，業界所期望的是能夠更進一步使方位 推進器的舵角小’並且’能夠抑制方位推進器所產生的振 -6- 201233589 動。 此外，專利文獻3所揭示的發明是一種根據船速轉換 舵角的方法，但業界所期望的是於實際航行時，能夠不拘 船速使方位推進器的舵角小。 本發明是有鑑於上述情況而爲的發明，課題爲提供一 種可使旋轉時的舵角小，能夠抑制旋轉所產生之振動的方 位推進器及具備該方位推進器之船舶。 [用以解決課題之手段] 本發明，爲了解決上述課題，採用下述手段。 根據本發明之一形態相關的方位推進器時，其特徵爲 ，具備：與容器設置成一體，具有長軸延伸在對該容器中 心軸線成大致正交方向的舵形狀舵板；及設置在上述容器 的端部，並且設置在上述舵板上游側的推進器，此外，於 上述舵板下游側長邊，設有複數分割在上述舵板之上述長 軸方向可彼此獨立動作的襟翼。 當使具有舵形狀舵板在推進器的下游側且該舵形狀舵 板與容器設置成一體的方位推進器旋轉時，推進器所產生 的水流會從推進器的後流被引導往容器及舵板的側面。 於是，本發明的方位推進器，就構成爲是在設置成與 上游側端部具有推進器的容器成一體的舵形狀舵板的下游 側長邊，設有複數分割在舵板長軸方向的襟翼。再加上， 該等複數襟翼，是各個可獨立動作。如此一來，就可根據 從推進器經過舵板側面被導向舵板下游側長邊之推進器的 201233589 水流方向使各襟翼動作。因此’就能夠不妨礙推進器產生 的水流使各襟翼動作，能夠降低舵阻力以小舵角就能夠使 方位推進器旋轉。此外，因襟翼能夠各個獨立動作，所以 位於想要使水流之流動大幅改變之位置上的襟翼其大幅動 作就能夠增加舵力。因此，能夠提高方位推進器之旋轉性 能的同時，能夠抑制方位推進器旋轉時的船體振動及相關 機器的振動。 上述形態相關的方位推進器，也可構成爲是於上述舵 板的上游側長邊，設有襟翼。 本發明的方位推進器，是構成爲在設置成與端部具有 推進器且該推進器設置在舵板上游側的容器成一體的舵形 狀舵板，於舵板的上游側長邊設有襟翼。如此一來，推進 器轉動時產生的水流及方位推進器旋轉時產生旋流就可由 襟翼加以整流，導向容器及舵板的側面。因此，能夠降低 舵阻力使方位推進器以小舵角旋轉。基於此，是能夠提高 方位推進器的旋轉性能。 上述構成相關的方位推進器，也可構成爲上述襟翼複 數分割在上述舵板的上述長軸方向可ρ此獨立動作。 本發明的方位推進器，是於舵板的上游側長邊，設有 複數分割在舵板長軸方向的襟翼，構成爲可使各襟翼各自 獨立動作。因此，就可根據推進器產生的水流方向配合襟 翼的動作加以整流。基於此，就能夠減少急遽的水流變化 ，能夠抑制對舵板之負荷及振動的產生。 上述形態相關的方位推進器，也可構成爲是於上述舵 -8- 201233589 板的側面，至少具備有1個沿著上述推進器旋轉產生的水 流方向從上述舵板的上游側長邊延伸至下游側長邊的整流 手段。 本發明的方位推進器，是構成爲在舵板的側面設有沿 著推進器旋轉產生的水流方向延伸的整流手段。如此一來 ，就能夠對被導向舵板側面之來自於推進器的水流加以整 流使水流從舵板的上游側長邊導向下游側長邊。因此，被 導向舵板下游側長邊的水流就不會產生亂流，基於此就能 夠始設置在舵板下游側長邊的襟翼有效動作。 上述構成相關的方位推進器，也可構成爲是將上述整 流手段設置成能夠轉動在上述舵板的側面上。 本發明的方位推進器，是構成爲設有能夠轉動在舵板 側面上的整流手段。因此，就能夠配合潮汐水流變化及推 進器旋轉數變化所造成之導向舵板的水流變化來改變整流 手段的延伸方向。基於此，就能夠應對複雜的水流。 本發明相關的船舶，具備有上述任一項所記載的方位 推進器。 本發明的船舶，是使用小舵角並且能夠獲得大旋轉力 的方位推進器。因此，能夠提高船舶之旋轉能力的同時， 能夠降低水流變化所導致的振動。 [發明效果] 根據上述本發明的方位推進器時，是在設置成與具有 推進器在舵板上游側端部的容器成一體的舵形狀舵板的下 -9- 201233589 游側長邊，設有複數分割在舵板長軸方向的襟翼。再加上 ，該等複數襟翼，是各個可獨立動作。如此一來，就可根 據從推進器經過舵板側面被導向舵板下游側長邊之推進器 的水流方向使各襟翼動作。因此，就能夠不妨礙推進器所 產生的水流使各襟翼動作，能夠降低舵阻力以小舵角就能 夠使方位推進器旋轉。此外，·因襟翼能夠各個獨立動作， 所以位於想要使水流之流動大幅改變之位置上的襟翼其大 幅動作就能夠增加舵力。因此，能夠提高方位推進器之旋 轉性能的同時，能夠抑制方位推進器旋轉時的船體振動及 相關機器的振動。 【實施方式】 [發明之最佳實施形態] [第1實施形態] 以下，根據第1圖針對設置在本發明相關之船舶的方 位推進器進行說明。 第1圖爲舶用推進裝置的一例，表示方位推進器的槪 略構成例。圖示的方位推進器1A，是一種安裝在船舶（ 未圖示）之船尾等使用的舶用推進裝置。該方位推進器 1 A，是機械性傳達船舶之船內所設置之動力源（未圖示 )的動力，對透過舵形狀的舵板4安裝在船體的容器2的 螺旋槳（推進器）3進行驅動藉此獲得推進力的裝置。再 加上，該方位推進器1A，是透過容器2與具有舵功能之 舵板4 一體對船舶成旋轉，就能夠改變船舶的推進（航行 -10- 201233589 )方向。 舵板4,是與容器2設置成一體，具有長軸延伸在對 容器2的中心軸線成大致正交的方向。舵板4，以設有水 平剖面爲舵形狀的區域使其兼爲舵。即，舵板4，是由具 有舵形狀的水平剖面，包括有與船舶連結的連結軸的上部 舵板4a，和，延伸至容器2的下方，具有相同舵剖面形 狀的下部舵板4b所構成。具備有舵板4及螺旋槳3的容 器2，是由未圖示的旋轉裝置使其對船舶成一體旋轉。 在舵板4之船尾側（下游側，第1圖中的左側）的長 邊（下游側長邊），設有複數分割在舵板4長軸方向的襟 翼5。複數的襟翼5，是設置成遍佈在舵板4之船尾側的 —邊，例如是分割成6個。各襟翼5a、5b、5c、5d、5e 、5f，例如是由鉸鏈（未圖示）等固定在舵板4之船尾側 的一邊。複數的襟翼5a、5b、5c、5d、5e、5f，是各個可 獨立動作。 容器2，是大致繭形狀。容器2，是以其長軸大致正 交於舵板4之長軸的狀態設置在上部舵板4a和下部舵板 4b之間。 螺旋槳3，是容器2之船頭側（第1圖中右側）的端 部，設置在舵板4的上游側。 其次，針對方位推進器1A旋轉時的控制方法進行說 明。 利用設置在船舶之船內的旋轉裝置使其螺旋槳3成旋 轉驅動的方位推進器1 A旋轉。於此時，使設置在方位推 -11 - 201233589 進器1A構成用之舵板4之船尾側的複數襟翼5a、5b、5c 、5d、5e、‘5f各個獨立彎折（動作）。 螺旋槳3旋轉驅動所產生的水流，如第1(A)圖及 第1(C)圖的箭頭符號所示’是會從螺旋槳3的後流沿 著容器2及舵板4的側面導向船尾側。 藉由將設置在舵板4之船尾側的襟翼5a、5b、5c、 5d、5e、5f例如朝紙面前方彎折，是會使導向舵板4之船 尾側的水流流動方向有2個階段的改變。 可使導向舵板4之船尾側的水流流動方向改變的襟翼 5a、5b、5c、5d、5e、5f，是分割成能夠各個獨立動作。 因此’例如：第1(A)圖所示，可將在容器2附近位於 容器2下方的襟翼5d彎折成使該襟翼5d的傾斜角度大， 其他以外的襟翼5a、5b、5c、5e、5f彎折時該等的傾斜 角度比襟翼5d小，或者，使該等不彎折等。 如上述，藉由設置在舵板4之船尾側一邊的複數襟翼 5a、5b、5c、5d、5e、5f的各個獨立彎折，是能夠不妨礙 螺旋槳3旋轉所產生的水流使水流的流動方向大幅改變。 因此’在旋轉方位推進器1A時，藉由各襟翼5a、5b 、5c、5d、5e、5f的彼此獨立彎折，對導向舵板4之船尾 側的水流流動方向進行改變，就能夠不產生急遽水流變化 使方位推進器1A旋轉。基於此，就能夠抑制作用在舵板 4之負荷及水流之急遽變化所造成的振動。 如以上說明，根據本實施形態相關的方位推進器1 a 及具備該方位推進器1A的船舶時，是可達到以下的作用 -12- 201233589 效果。 方位推進器1A，是在設置成與舵板4之船頭側（上 游側）端部具有螺旋槳（推進器）3的容器2成一體的舵 形狀舵板4之船尾側的長邊（下游側長邊）’設有分割成 6個（複數分割）在舵板4長軸方向的襟翼5a、5b、5c、 5d、5e、5f。再力口上，該等襟翼 5a' 5b、5c、5d、5e、5f ，是各個可獨立動作。如此一來，就可根據從螺旋槳3經 過舵板4的側面被導向舵板4之船尾側長邊的螺旋槳3的 水流方向使各襟翼5a、5b、5c、5d、5e、5f動作。因此 ，就能夠不妨礙螺旋槳3所產生的水流使各襟翼5 a、5b _、5 c、5 d、5 e、5 f彎折（動作），能夠降低蛇阻力以小舵 角就能夠使方位推進器1 A旋轉。此外，因襟翼5a、5b、 5c、5d、5e、5f能夠各個獨立動作，所以位於想要使水流 之流動大幅改變之位置上的襟翼5d其大幅彎折就能夠增 加舵力。因此，能夠提高方位推進器1 A之旋轉性能的同 時，能夠抑制方位推進器1 A旋轉時的船體振動及相關機 器的振動。 本實施形態的船舶，是使用小舵角並且能夠獲得大旋 轉力的方位推進器1A。因此，能夠提高船舶之旋轉能力 的同時，能夠降低水流變化所導致的振動。 另，各襟翼 5a、5b、5c' 5d' 5e、5f的彎折角度， 是可根據事先實驗等所獲得的基礎數據加以決定，此外， 也可從船舶的航行中取得。再加上，也可在航行中適當修 正初期的數據。 -13- 201233589 [第2實施形態] 本實施形態的方位推進器及具備該方位 ，其與第1實施形態不同之處是在舵板的船 ，除此之外其他構成相同。因此，對於相同 方法，是標示相同的圖號省略其說明。

1B旋轉時產生的旋流進行整流。因此，能夠提高方位推 進器1B之舵板4的揚力進行旋轉。基於此，以小舵角就 能使船舶旋轉 如以上說明，根據本實施形態相關的方位推進器1 B 及具備該方位推進器1B的船舶時，是可達到以下的作用 效果。 方位推進器1B，是在設置成與舵板4之船頭側（上 游側）端部具有螺旋槳（推進器）3的容器2成一體的舵 形狀舵板4 ’於該舵板4之船頭側的長邊（上游側長邊） ，設有襟翼6。如此一來’利用襟冀6對螺旋獎3所產生 -15- 201233589 的水流及方位推進器1 B。旋轉時產生的旋流進行整流，就 能夠使水流導向容器2及舵板4的側面。因此，能夠降低 舵阻力以小舵角就能夠使方位推進器1 B旋轉。基於此， 就能夠提高方位推進器1 B之旋轉性能。 另，本實施形態中，是以舵板4之船頭側的長邊設有 襟翼6爲例子進行的說明，但本發明並不限於此，也可採 用整流板取代襟翼6。 此外，襟翼6的彎折角度，是可根據事先實驗等所獲 得的基礎數據加以決定，另外，也可從船舶的航行中取得 。再加上，也可在航行中適當修正初期的數據。 [第3實施形態] 本實施形態的方位推進器及具備該方位推進器的船舶 ，其與第2實施形態不同之處是在舵板的船頭側設置複數 的襟翼，除此之外其他構成相同。因此，對於相同的構成 及控制方法，是標示相同的圖號省略其說明。 第3圖中，圖示著本實施形態的方位推進器1C槪略 構成例。 本實施形態的方位推進器1 c ’是在舵板4的船尾側 設有分割成6個的襟翼5a、5b、5c、5d、5e、5f’同時在 舵板4的船頭側（上游側，第3圖中右側）’於螺旋槳（ 推進器）3之後流附近的長邊（上游側長邊）設有複數分 割（例如分割成6個）在舵板4長軸方向的襟翼7° 複數的襟翼7，是設置成遍佈在舵板4之船頭側的— -16-

此時，使設置在方位推進器1C構成用之舵板4之船頭側 的複數襟翼 7a、7b、7c、7d、7e、7f各個獨立彎折（動 作）。此外，又使設置在舵板4之船尾側的複數襟翼5a 、5b、5c、5d、5e、5f各個獨立彎折。 螺旋槳3旋轉驅動所產生的水流，及，方位推進器 1C旋轉所產生的旋流，如第3(A)圖及第3(C)圖的 箭頭符號所示，是會從螺旋槳3的後流導向襟翼7。於此 ，襟翼7a、7b、7c、7d、7e、7f是分割成各個能夠獨立 動作。因此，藉由將設置在舵板4之船頭側的複數襟翼7 當中靠近容器2位於容器2下方的襟翼7d彎折成使該襟 翼7d傾斜角度大，其他以外的襟翼7a、7b、7c、7e、7f 彎折時該等的傾斜角度比襟翼7d小，或者，使該等不彎 折等。 如上述，藉由設置在舵板4之船頭側一邊的複數襟翼 7a、7b、7c、7d、7e、7f的各個獨立動作，是能夠不妨礙 螺旋槳3旋轉所產生的水流使水流的流動方向大幅改變。 -17- 201233589 因此，在旋轉方位推進器1C時’藉由各襟翼7a、7b 、7c、7d、7e、7f的獨立彎折，改變從舵板4的船頭側導 向舵板4之船尾側的水流流動方向’就能夠不產生急遽水 流變化使方位推進器1 C旋轉。基於此’就能夠抑制作用 在舵板4之負荷及水流之急遽變化所造成的振動。 如以上說明，根據本實施形態相關的方位推進器1C 及具備該方位推進器1C的船舶時’是可達到以下的作用 效果。 方位推進器1C，是在舵板4之船頭側的長邊（上游 側長邊），設有分割成6個（複p分割）在舵板4長軸方 向的襟翼 7a、7b、7c、7d、7e、7f，各襟翼 7a、 7b、 7c 、7d、7e、7f，是各個可獨立彎折（動作）。因此，就可 根據螺旋槳（推進器）3產生的水流方向配合襟翼7a、7b

，其與第3實施形態不同之處是在舵板的側面設有溝槽’ -18- 201233589 除此之外其他構成相同。因此，對於相同的構成及控制方 法，是標示相同的圖號省略其說明。 第4圖中，圖示著本實施形態的方位推進器1D槪略 構成例。 本實施形態的方位推進器1 D，是於舵板4的側面具 備有例如4個（至少1個）整流板（整流手段）8，該整 流板8是沿著螺旋槳（推進器）3旋轉所產生的水流方向 從舵板4之船頭側的長邊（上游側長邊）延伸至船尾側的 長邊（下游側長邊）。 於本實施形態的說明時，是以螺旋槳的旋轉方向從船 頭側（第4圖的右側）看爲順時針旋轉時來行說明。 整流板8，是大致長方形，於本實施形態時，整流板 8是從舵板4的船頭側朝船尾側往下方傾斜設置成4個。 其次，針對方位推進器1D旋轉時的控制方法進行說 明。 利用設置在船舶之船內（未圖示）的旋轉裝置（未圖

箭頭符號所示，是會從螺旋槳3的後流導向襟翼7。於此 -19- 201233589 ’襟翼7a、7b、7c、7d、7e、7f是分割成各個能夠獨立 動作。因此’藉由將設置在舵板4之船頭側的複數襟翼7 當中靠近容器2位於容器2下方的襟翼7d彎折（動作） 成使該襟翼傾斜角度大，其他以外的襟翼7a、7b、7c 、7e、7f彎折時該等的傾斜角度比襟翼7d小，.或者，使 該等不彎折等。 經由設置在舵板4之船頭側的複數襟翼7a、7b、7c 、7d、7e、7f改變流動方向的水流會被導向舵板4的側面 。被引導至舵板4側面的水流，是會沿著設置在舵板4的 整流板8順著整流後的流動方向被導往船尾側。 如上述，經由整流板8整流過流動方向的水流會被導 向設置在舵板4之船尾側的各襟翼5a、5b、5c、5d、5e 、5f，因此就能夠有效果地使各襟翼5a、5b、5c、5d、5e 、5 f彎折。 如以上說明，根據本實施形態相關的方位推進器1 D 及具備該方位推進器1D的船舶時，是可達到以下的作用 效果。 方位推進器1D，是在舵板4的側面設有沿著螺旋槳 (推進器）3產生的水流方向延伸的整流板（整流手段） 8。如此一來，就能夠對被引導至舵板4側面之來自於螺 旋槳的水流進行整流使水流從舵板4之船頭側的長邊（上 游側長邊）導向舵板4之船尾側的長邊（下游側長邊）。 基於此，被導向舵板4之船尾側長邊的水流就不會產生亂 流，因此，就能夠有效果地使設置在舵板4之船尾側長邊 -20- 201233589 的襟翼5a、5b' 5c、5d、5e、5f彎折（動作）。 另，本實施形態中，整流手段是以整流板8進行了說 明，但本發明並不限於此，整流手段也可以是溝槽。 此外，本實施形態中，是對整流板8的傾斜方向從舵 板4的船頭側朝船尾側往下方傾斜的例子進行了說明’但 本發明並不限於此，整流板8的傾斜方向只要設置成可使 螺旋槳3旋轉產生的水流方向往上下方向傾斜即可。 [第5實施形態] 本實施形態的方位推進器及具備該方位推進器的船舶 ，其與第4實施形態不同之處是設置在舵板之側面的整流 板對舵板的側面成平行轉動，除此之外其他構成相同。因 此，對於相同的構成及控制方法，是標示相同的圖號省略 其說明。 第5圖中，圖示著本實施形態的方位推進器1E槪略 構成例。 在本實施形態之方位推進器1E的舵板4側面，是設 有能夠轉動在舵板4側面上的整流板9。 整流板9’是大致長方形，於本實施形態時，整流板 8是從舵板4的船頭側（上游側）朝船尾側（下游側）往 下方傾斜設置成8個。該等8個整流板9，是從舵板4的 船頭側朝船尾側設置成2列，於各列，整流板9平行設置 成4個。 各整流板9’其長度方向的大致中心貫通有旋轉軸9a -21 - 201233589 。旋轉軸9a，是從紙面的前方朝舵板4的側面貫通整流 板9。如此一來，整流板9，就能夠對舵板4的側面成平 行繞著旋轉軸9a轉動，整流板9之延伸方向的傾斜角度 是可變。如上述設置在舵板4之側面的各整流板9，是各 個可彼此獨立轉動。 其次，針對方位推進器1E旋轉時的控制方法進行說 明。 利用設置在船舶之船內（未圖示）的旋轉裝置（未圖 示）使其螺旋槳（推進器）3成旋轉驅動的方位推進器1E

Description of the Invention: [Technical Field] The present invention relates to an azimuth ejector having a rudder plate integrated with a container. [Prior Art] Previously, the azimuth thruster which can move the ship in any direction and correctly maintain the current position of the ship, as shown in Fig. 6, is to mount the container 2, the propeller 3 and the rudder plate 4 at the stern of the ship S or the like. The rudder plate 4 of this form is an upper rudder plate 4a having a horizontal cross section of a rudder shape and including a connecting shaft portion to be coupled to the ship S, and a lower rudder having a rudder cross-sectional shape extending downward below the streamline 2 The plate 4b is constructed. The container 2 having the rudder plate 4 and the propeller 3 is integrally rotatable to the ship S. Further, in the ship of the ship S, the prime mover 5 is provided, and the motive power of the prime mover 5 is transmitted to the propeller 3 via the two sets of bevel gear units 6 and 7 provided in the container 2. The azimuth propeller 1 configured as described above has a function of rotating the rudder plate 4 by a rotating device (not shown) provided in the hull S, thereby having a function of changing the rudder of the ship S in the navigation direction. Rotating the azimuth thruster 1 by 180 ° is capable of causing the ship S to sail in the backward direction. In order to rotate the ship S for a short time and rotate the azimuth propeller 1 at a large rudder angle, the flow of water flowing as indicated by the arrow symbol from the right side of the paper to the left side in Fig. 6 acts on the downstream side (stern side) of the rudder plate 4 The set propeller 201233589 acts on the propeller 3 in which the water flow ' acts on the propeller 3 at the same large angle as the rudder angle. Therefore, the propeller 3 is rotated in a diagonal flow having the same large angle as the rudder angle, resulting in a large variation in the force generated by the propeller 3. The large force fluctuation generated by the propeller 3 causes the azimuth thruster 1 to vibrate as a whole, and the vibration is transmitted to the ship S and the related equipment (not shown) to cause a malfunction. In order to suppress the fluctuation of the force acting on the azimuth thruster as described above, the technique disclosed in Patent Document 1 is a rudder plate on the downstream side of the propeller, and a flap having a length substantially equal to the long side of the rudder plate is provided. Further, in Patent Document 2, the technique disclosed is that the shape of the steering plate is previously formed to be asymmetrical. In Patent Document 3, the disclosed technique is such that one container is placed between two rudder plates, and the rudder angle is converted in accordance with the ship speed. [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-193189 [Patent Document 2] JP-A-2002-193189 (Patent Document 3) Bulletin [Summary of the Invention] [Problems to be Solved by the Invention] However, in recent years, it has been desired in the industry to further reduce the steering angle of the azimuth thruster and to suppress the vibration generated by the azimuth thruster - 201233589 . Further, the invention disclosed in Patent Document 3 is a method of switching the steering angle in accordance with the ship speed, but it is expected in the industry that the steering angle of the azimuth thruster can be made small at an actual speed during the actual sailing. The present invention has been made in view of the above circumstances, and an object of the invention is to provide a positional propeller capable of suppressing vibration generated by rotation and having a small steering angle during rotation, and a ship including the azimuth propeller. [Means for Solving the Problem] In order to solve the above problems, the present invention employs the following means. According to another aspect of the present invention, an azimuth thruster includes: a rudder shape rudder plate integrally provided with a container and having a long axis extending in a substantially orthogonal direction to a center axis of the container; and The end of the container is provided with a pusher on the upstream side of the rudder plate, and a plurality of flaps that are independently movable in the longitudinal direction of the rudder plate are provided on the long side of the downstream side of the rudder plate. When the azimuth thruster having the rudder shape rudder plate on the downstream side of the propeller and the rudder shape rudder plate and the container are integrally rotated, the water flow generated by the propeller is guided from the rear flow of the propeller to the container and the rudder The side of the board. Therefore, the azimuth thruster of the present invention is configured such that it is disposed on the downstream side of the rudder-shaped rudder plate integrally formed with the container having the propeller at the upstream end portion, and is provided with a plurality of divisions in the longitudinal direction of the rudder plate. Flaps. In addition, the plurality of flaps are each independently operable. In this way, the flaps can be actuated according to the flow direction of the 201233589 water flow from the propeller through the side of the rudder plate to the long side of the downstream side of the rudder plate. Therefore, it is possible to operate the flaps without hindering the flow of water generated by the propeller, and it is possible to reduce the rudder resistance and rotate the azimuth thruster with a small rudder angle. In addition, since the flaps can be independently operated, the flaps at a position where the flow of the water flow is desired to be greatly changed can increase the steering force. Therefore, it is possible to improve the rotational performance of the azimuth thruster and suppress the vibration of the hull and the vibration of the related machine when the azimuth thruster rotates. The azimuth thruster according to the above aspect may be configured such that it is provided on the long side of the upstream side of the rudder plate, and is provided with a flap. The azimuth propeller of the present invention is configured as a rudder-shaped rudder plate integrally provided with a container having a propeller at an end portion and provided on the upstream side of the rudder plate, and is provided on the long side of the upstream side of the rudder plate. wing. In this way, the water flow generated when the propeller rotates and the swirl generated during the rotation of the azimuth propeller can be rectified by the flaps to the side of the container and the rudder plate. Therefore, the rudder resistance can be lowered to rotate the azimuth thruster at a small rudder angle. Based on this, it is possible to improve the rotation performance of the azimuth thruster. The azimuth thruster according to the above configuration may be configured such that the plurality of flaps can be independently operated in the longitudinal direction of the rudder plate. The azimuth propeller of the present invention is provided on the long side of the upstream side of the rudder plate, and is provided with a plurality of flaps divided in the longitudinal direction of the rudder plate, and is configured to allow the respective flaps to operate independently. Therefore, it can be rectified according to the direction of the water flow generated by the propeller and the action of the flap. Based on this, it is possible to reduce the rapid change of the water flow, and it is possible to suppress the load and vibration of the rudder plate. The azimuth thruster according to the above aspect may be configured such that at least one of the side faces of the rudder-8-201233589 plate extends from the upstream side of the rudder plate to the long side of the rudder plate. The rectification means on the long side of the downstream side. The azimuth thruster of the present invention is configured such that a rectifying means extending in the direction of the water flow generated by the rotation of the propeller is provided on the side surface of the rudder plate. In this way, the flow of water from the propeller that is guided to the side of the rudder plate can be rectified so that the water flow is directed from the long side of the upstream side of the rudder plate to the long side of the downstream side. Therefore, the flow of water directed to the long side of the downstream side of the rudder plate does not cause turbulence, and based on this, the flaps which are disposed on the long side of the downstream side of the rudder plate can be effectively operated. The azimuth thruster according to the above configuration may be configured such that the rectifying means is rotatably provided on a side surface of the rudder plate. The azimuth thruster of the present invention is configured to be provided with a rectifying means that is rotatable on the side surface of the rudder plate. Therefore, it is possible to change the direction in which the rectifying means extends in accordance with the change in the flow of the steering rudder caused by the change in the tidal current and the change in the number of revolutions of the pusher. Based on this, it is able to cope with complex water flows. A ship according to the present invention includes the azimuth propeller described in any one of the above. The ship of the present invention is an azimuth thruster that uses a small steering angle and is capable of obtaining a large rotational force. Therefore, it is possible to improve the rotation ability of the ship and to reduce the vibration caused by the change in the water flow. [Effect of the Invention] According to the azimuth thruster of the present invention described above, the long side of the lower side of the -9-201233589, which is provided integrally with the container having the thruster at the upstream end of the rudder plate, is provided. There are multiple flaps that split the long axis of the rudder plate. In addition, the plurality of flaps are each independently operable. In this way, the flaps can be actuated according to the flow direction of the propeller from the propeller through the side of the rudder plate to the long side of the downstream side of the rudder plate. Therefore, it is possible to operate the flaps without hindering the flow of water generated by the propeller, and it is possible to reduce the rudder resistance and rotate the azimuth propeller with a small rudder angle. In addition, since the flaps can operate independently, the flaps can be increased in large-scale motion at a position where the flow of the water flow is to be greatly changed. Therefore, it is possible to improve the rotation performance of the azimuth thruster while suppressing the vibration of the hull and the vibration of the related machine when the azimuth thruster rotates. [Embodiment] [First Embodiment of the Invention] Hereinafter, a positional thruster provided in a ship according to the present invention will be described with reference to Fig. 1 . Fig. 1 is a view showing an example of a configuration of an azimuth propeller. The azimuth thruster 1A shown in the drawing is a marine propulsion device that is attached to a stern or the like of a ship (not shown). The azimuth propeller 1A is a propeller (propeller) 3 that is mechanically transmitted to a power source (not shown) provided in a ship of a ship, and is attached to a rudder plate 4 that is transmitted through a rudder shape to a container 2 of a hull. A device that drives to obtain propulsion. Further, the azimuth propeller 1A can change the direction of propulsion (voyage -10- 201233589) of the ship by rotating the container 2 integrally with the rudder plate 4 having the rudder function. The rudder plate 4 is integrally formed with the container 2 and has a long axis extending in a direction substantially orthogonal to the central axis of the container 2. The rudder plate 4 is also provided with a rudder in a region having a rudder shape with a horizontal cross section. That is, the rudder plate 4 is composed of a horizontal cross section having a rudder shape, an upper rudder plate 4a including a connecting shaft coupled to the ship, and a lower rudder plate 4b extending to the lower side of the container 2 and having the same rudder cross-sectional shape. . The container 2 including the rudder plate 4 and the propeller 3 is integrally rotated with respect to the ship by a rotating device (not shown). The long side (long side of the downstream side) of the stern side (downstream side, the left side in Fig. 1) of the rudder plate 4 is provided with a plurality of flaps 5 divided in the longitudinal direction of the rudder plate 4. The plurality of flaps 5 are provided so as to be distributed over the stern side of the rudder plate 4, for example, divided into six. Each of the flaps 5a, 5b, 5c, 5d, 5e, and 5f is fixed to one side of the stern side of the rudder plate 4 by a hinge (not shown) or the like, for example. The plurality of flaps 5a, 5b, 5c, 5d, 5e, 5f are each independently operable. The container 2 has a substantially meandering shape. The container 2 is disposed between the upper rudder plate 4a and the lower rudder plate 4b in a state in which the long axis thereof is substantially orthogonal to the long axis of the rudder plate 4. The propeller 3 is an end portion of the bow side (the right side in Fig. 1) of the container 2, and is provided on the upstream side of the rudder plate 4. Next, a description will be given of a control method when the azimuth thruster 1A is rotated. The azimuth propeller 1 A, which is driven to rotate by the propeller 3, is rotated by a rotating device provided in the ship of the ship. At this time, the plurality of flaps 5a, 5b, 5c, 5d, 5e, and "5f, which are provided on the stern side of the rudder plate 4 for the azimuth -11 - 201233589 ejector 1A, are independently bent (operated). The water flow generated by the rotational driving of the propeller 3, as indicated by the arrow symbols in the first (A) and the first (C) diagrams, is guided from the rear flow of the propeller 3 to the stern side along the sides of the container 2 and the rudder plate 4. . By bending the flaps 5a, 5b, 5c, 5d, 5e, 5f provided on the stern side of the rudder plate 4, for example, toward the front of the paper surface, the flow direction of the water on the stern side of the steering rudder 4 has two stages. Change. The flaps 5a, 5b, 5c, 5d, 5e, and 5f which change the flow direction of the water flow on the stern side of the rudder plate 4 can be divided into independent movements. Therefore, for example, as shown in Fig. 1(A), the flap 5d located below the container 2 in the vicinity of the container 2 can be bent so that the inclination angle of the flap 5d is large, and the flaps 5a, 5b, 5c other than the flaps 5a, 5b, 5c When the 5e and 5f are bent, the inclination angles are smaller than the flaps 5d, or the bends are not bent. As described above, each of the plurality of flaps 5a, 5b, 5c, 5d, 5e, and 5f provided on one side of the stern side of the rudder plate 4 is independently bent, and the flow of water can be prevented without obstructing the flow of the propeller 3. The direction has changed dramatically. Therefore, when the azimuth propeller 1A is rotated, by changing the flaps 5a, 5b, 5c, 5d, 5e, 5f independently of each other, the flow direction of the water flowing to the stern side of the steering rudder 4 is changed, so that The sudden change in the flow of water causes the azimuth thruster 1A to rotate. Based on this, it is possible to suppress the vibration caused by the sudden change in the load acting on the rudder plate 4 and the water flow. As described above, according to the azimuth propeller 1 a and the ship including the azimuth propeller 1A according to the present embodiment, the following effects can be achieved -12-201233589. The azimuth thruster 1A is a long side (downstream side) of the stern side of the rudder shape rudder plate 4 which is integrally formed with the container 2 having the propeller (propeller) 3 at the bow side (upstream side) end portion of the rudder plate 4 The side is provided with six (multiple divided) flaps 5a, 5b, 5c, 5d, 5e, and 5f in the longitudinal direction of the rudder plate 4. Further, the flaps 5a' 5b, 5c, 5d, 5e, 5f are independently operable. In this manner, the flaps 5a, 5b, 5c, 5d, 5e, and 5f can be operated in accordance with the flow direction of the propeller 3 which is guided from the propeller 3 to the long side of the stern side of the rudder plate 4 via the side surface of the rudder plate 4. Therefore, it is possible to bend (operate) the flaps 5a, 5b_, 5c, 5d, 5e, and 5f without hindering the flow of water generated by the propeller 3, and it is possible to reduce the resistance of the snake with a small steering angle. The azimuth thruster 1 A rotates. Further, since the flaps 5a, 5b, 5c, 5d, 5e, and 5f can be independently operated, the flap 5d located at a position where the flow of the water flow is to be largely changed can greatly increase the steering force. Therefore, while the rotation performance of the azimuth thruster 1 A can be improved, the vibration of the hull and the vibration of the related machine when the azimuth thruster 1 A is rotated can be suppressed. The ship of the present embodiment is an azimuth propeller 1A that uses a small steering angle and can obtain a large rotational force. Therefore, it is possible to improve the rotation ability of the ship and to reduce the vibration caused by the change in the water flow. Further, the bending angle of each of the flaps 5a, 5b, 5c' 5d' 5e, 5f can be determined based on basic data obtained by prior experiments or the like, and can also be obtained from the navigation of the ship. In addition, the initial data can be properly corrected during the voyage. -13-201233589 [Second Embodiment] The azimuth propeller of the present embodiment and the ship having the same orientation as those of the first embodiment are the same as those of the ship of the rudder plate. Therefore, for the same method, the same reference numerals are used to omit the description. In the second drawing, an example of the configuration of the azimuth pushing in the present embodiment is shown. In the azimuth propeller 1 B of the present embodiment, the rudder is provided with six flaps 5a, 5b, 5c, 5d, and 5e on the bow side (upstream side, right side in FIG. 2) of the rudder plate 4. The long side near the flow after 3 (the upstream side long side: the wing 6. The flap 6 is a bow wing 6 which is provided so as to be spread over the rudder board 4, and is fixed to the rudder board side by a hinge (not shown), for example. Next, the azimuth thruster that rotates the propeller 3 by the rotation of the azimuth propeller 1B by the rotation of the ship (not shown) is set to the azimuth propeller 1B. The flap 6 that constitutes the rudder ί is bent (acting). In addition, the water flow generated by the rotation of the propellers 3 of the plurality of flaps 5a, 5b, 5c, 5d, 5e, 5f provided on the side, and the configuration of the flaps on the head side of the propeller and the controller 1B The stern side of the stern: 4, 5f, at the same time, there is one side of the raft on the propeller ( ). The method of the bow side of the 襟4 is carried out by the transfer device (not shown in Fig. 1B. The stern of the bow 4 on the bow side of the reverse 4 is bent independently. The azimuth thruster-14-201233589 1B is rotated by the rotation of the 1B] The arrow marks in the second (A) and second (C) diagrams indicate that the flap 6 is guided from the rear flow of the propeller 3. The flap 6 provided on the bow side of the rudder plate 4 is the second. (C), for example, bending toward the front of the paper surface is the flow direction of the water flow generated by the propeller 3 guided to the bow side of the rudder plate 4, and the flow of the swirl flow generated by the rotation of the azimuth propeller 1B. The direction changes. The flow of the propeller 3 and the swirl of the azimuth thruster 1B after the flap 6 changes the flow direction are directed to the stern side along the sides of the container 2 and the rudder plate 4. Guided to the stern of the rudder plate 4 The water flow and the swirl flow on the side are bent, for example, toward the front of the paper via the flaps 5a, 5b, 5c, 5d, 5e' 5f provided on the stern side of the rudder plate 4, as indicated by the arrow symbol in the second (C) diagram. , the flow direction has three stages of change. As described above, when the side of the bow side of the segment plate 4 adjusts the inclination angle of the flap 6, It is possible to rectify the flow of water generated by the propeller 3 and the swirl generated when the azimuth propeller 1B rotates. Therefore, it is possible to increase the swing force of the rudder plate 4 of the azimuth propeller 1B and to rotate it. As described above, the azimuth thruster 1 B according to the present embodiment and the ship including the azimuth propeller 1B can achieve the following operational effects. The azimuth thruster 1B is disposed in the same manner as the steering plate 4 The bow side (upstream side) end has a container 2 of a propeller (propeller) 3 and an integral rudder shape rudder plate 4' on the long side (upstream side long side) of the bow side of the rudder plate 4, and a flap 6 is provided. In this way, the water flow and azimuth thruster 1 B generated by the 襟冀6 pairs of the spiral prize 3 -15-201233589. The rectification of the swirl generated during the rotation enables the water flow to be directed to the sides of the container 2 and the rudder plate 4. Therefore, it is possible to reduce the rudder resistance and rotate the azimuth propeller 1 B with a small rudder angle. Based on this, the rotation performance of the azimuth propeller 1 B can be improved. In the present embodiment, the bow of the rudder plate 4 is used. Side long side The flap 6 is described as an example, but the present invention is not limited thereto, and a rectifying plate may be used instead of the flap 6. Further, the bending angle of the flap 6 may be based on basic data obtained by prior experiments or the like. In addition, it is also possible to obtain the initial data from the voyage of the ship. In addition, the initial data may be appropriately corrected during the voyage. [A third embodiment] The azimuth propeller of the present embodiment and the ship including the azimuth propeller are The difference from the second embodiment is that a plurality of flaps are provided on the bow side of the rudder plate, and the other configurations are the same. Therefore, the same configurations and control methods are denoted by the same reference numerals and the description thereof is omitted. In the third drawing, a schematic configuration example of the azimuth propeller 1C of the present embodiment is shown. The azimuth propeller 1 c ' of the present embodiment is provided with six flaps 5a, 5b, 5c, 5d, 5e, and 5f' which are divided into six on the stern side of the rudder plate 4 while being on the bow side of the rudder plate 4 (upstream side) , the right side in Fig. 3) 'The long side (upstream side long side) near the flow after the propeller (propeller) 3 is provided with a plurality of divisions (for example, divided into six) flaps 7° in the longitudinal direction of the rudder plate 4 The plurality of flaps 7 are disposed on the side of the bow of the rudder plate 4 from -16 to 201233589, and are divided into six in the longitudinal direction of the rudder plate 4" respective flaps 7a, 7b, 7c, 7d, 7e 7f is fixed to one side of the bow side of the rudder plate 4 by, for example, a hinge (not shown). The plurality of flaps 7a, 7b, 7c, 7d, 7e, and y are each independently operable. Next, a description will be given of a control method when the azimuth thruster 1C is rotated. The azimuth propeller 1C that rotationally drives the propeller 3 is rotated by a rotating device (not shown) provided in a ship (not shown). At this time, the plurality of flaps 7a, 7b, 7c, 7d, 7e, and 7f provided on the bow side of the rudder plate 4 for constituting the azimuth propeller 1C are each independently bent (actuated). Further, the plurality of flaps 5a, 5b, 5c, 5d, 5e, and 5f provided on the stern side of the rudder plate 4 are each independently bent. The flow of water generated by the rotation of the propeller 3 and the swirl generated by the rotation of the azimuth propeller 1C, as indicated by the arrow symbols in the 3rd (A) and 3rd (C), are the flow from the propeller 3 Guide flaps 7. Here, the flaps 7a, 7b, 7c, 7d, 7e, and 7f are divided into individual operations. Therefore, the flaps 7d located below the container 2 in the plurality of flaps 7 provided on the bow side of the rudder plate 4 are bent so that the flaps 7d have a large inclination angle, and the other flaps 7a, 7b are When 7c, 7e, and 7f are bent, the inclination angles are smaller than the flaps 7d, or the bends are not bent. As described above, the independent operation of the plurality of flaps 7a, 7b, 7c, 7d, 7e, and 7f provided on the bow side of the rudder plate 4 is a flow direction in which the water flow can be prevented without hindering the rotation of the propeller 3. Greatly changed. -17- 201233589 Therefore, when the azimuth propeller 1C is rotated, the stern side of the steering plate 4 is changed from the bow side of the rudder plate 4 by the independent bending of the flaps 7a, 7b, 7c, 7d, 7e, 7f. The direction of flow of the water flow is such that the azimuth thruster 1 C can be rotated without causing a sudden change in the flow of water. Based on this, it is possible to suppress the vibration caused by the sudden change in the load acting on the rudder plate 4 and the water flow. As described above, according to the azimuth propeller 1C and the ship including the azimuth propeller 1C according to the present embodiment, the following effects can be obtained. The azimuth propeller 1C is a long side (upstream side long side) on the bow side of the rudder plate 4, and is provided with six (multiple p-divided) flaps 7a, 7b, and 7c in the longitudinal direction of the rudder plate 4, 7d, 7e, and 7f, each of the flaps 7a, 7b, 7c, 7d, 7e, and 7f is independently bendable (operating). Therefore, the flow of the flaps 7a, 7b, 7c, 7d, 7e, and 7f can be rectified in accordance with the flow direction of the water generated by the propeller (propeller) 3. Based on this, it is possible to reduce the rapid change of the water flow, and it is possible to suppress the load and vibration of the rudder plate 4, and the bending angle of each of the flaps 7a, 7b, 7c, 7d, 7e, and 7f can be experimentally based on prior experiments. It is determined by the basic data obtained, and it can also be obtained from the navigation of the ship. In addition, the initial data can be properly corrected during the voyage. [Fourth Embodiment] The azimuth propeller of the present embodiment and the ship including the azimuth propeller are different from the third embodiment in that a groove is provided on the side surface of the rudder plate -18-201233589. The other components are the same. Therefore, the same components and control methods are denoted by the same reference numerals and their descriptions are omitted. In the fourth drawing, a schematic configuration example of the azimuth propeller 1D of the present embodiment is shown. The azimuth thruster 1 D of the present embodiment includes, for example, four (at least one) rectifying plates (rectifying means) 8 on the side surface of the steering plate 4, and the rectifying plate 8 is rotated along the propeller (propeller) 3 The generated water flow direction extends from the long side (upstream side long side) of the bow side of the rudder board 4 to the long side (long side side long side) of the stern side. In the description of the present embodiment, the rotation direction of the propeller is described as being clockwise rotated from the bow side (the right side in Fig. 4). The flow regulating plate 8 has a substantially rectangular shape. In the present embodiment, the flow regulating plate 8 is formed to be inclined downward from the bow side of the rudder plate 4 toward the stern side. Next, a description will be given of a control method when the azimuth thruster 1D is rotated. The azimuth propeller 1D that rotationally drives the propeller 3 is rotated by a rotating device (not shown) provided in a ship (not shown). At this time, the plurality of flaps 7a, 7b, 7c, 7d, 7e, and 7f provided on the bow side of the rudder plate 4 for constituting the azimuth propeller 1D are independently bent (actuated). Further, the plurality of flaps 5a, 5b, 5c, 5d, 5e' 5f provided on the stern side of the rudder plate 4 are each independently bent. The flow of water generated by the rotation of the propeller 3 and the swirl generated by the rotation of the azimuth thruster 1D, as indicated by the arrow symbols in Figs. 4(A) and 4(C), are the flow from the propeller 3 Guide flaps 7. Here, -19-201233589' flaps 7a, 7b, 7c, 7d, 7e, and 7f are divided into individual and can operate independently. Therefore, the flaps 7d located below the container 2 in the plurality of flaps 7 provided on the bow side of the rudder plate 4 are bent (actuated) so that the flaps have a large inclination angle, and the other flaps 7a are When the 7b, 7c, 7e, and 7f are bent, the inclination angles are smaller than the flaps 7d, or the bends are not bent. The flow of water that changes the flow direction via the plurality of flaps 7a, 7b, 7c, 7d, 7e, 7f provided on the bow side of the rudder plate 4 is guided to the side of the rudder plate 4. The flow of water guided to the side of the rudder plate 4 is guided to the stern side along the rectified flow direction along the rectifying plate 8 provided on the rudder plate 4. As described above, the flow of water rectified in the flow direction via the flow regulating plate 8 is guided to the flaps 5a, 5b, 5c, 5d, 5e, and 5f provided on the stern side of the rudder plate 4, so that the flaps can be effectively effected. 5a, 5b, 5c, 5d, 5e, 5 f are bent. As described above, according to the azimuth thruster 1 D according to the present embodiment and the ship including the azimuth thruster 1D, the following operational effects can be obtained. The azimuth propeller 1D is provided with a rectifying plate (rectifying means) 8 extending in the direction of the water flow generated by the propeller (propeller) 3 on the side surface of the rudder plate 4. In this way, the flow from the propeller that is guided to the side of the rudder plate 4 can be rectified so that the water flow is directed from the long side (upstream side long side) of the bow side of the rudder plate 4 to the long side of the stern side of the rudder plate 4. (long side of the downstream side). Based on this, the flow of water directed to the long side of the stern side of the rudder plate 4 does not cause turbulent flow, and therefore, the flaps 5a, 5b provided on the long side of the stern side of the rudder plate 4 -20-201233589 can be effectively effected. '5c, 5d, 5e, 5f bend (action). Further, in the present embodiment, the rectifying means has been described with the rectifying plate 8, but the present invention is not limited thereto, and the rectifying means may be a groove. In the present embodiment, the example in which the inclination direction of the rectifying plate 8 is inclined downward from the bow side of the rudder plate 4 toward the stern side has been described. However, the present invention is not limited thereto, and the inclination direction of the rectifying plate 8 is only required to be set. It is sufficient that the direction of the water flow generated by the rotation of the propeller 3 can be inclined in the up and down direction. [Fifth Embodiment] The azimuth propeller of the present embodiment and the ship including the azimuth thruster are different from the fourth embodiment in that the rectifying plate provided on the side surface of the rudder plate rotates in parallel with the side surface of the rudder plate. Other than this, the composition is the same. Therefore, the same components and control methods are denoted by the same reference numerals and their descriptions are omitted. In the fifth drawing, a schematic configuration example of the azimuth propeller 1E of the present embodiment is shown. On the side surface of the rudder plate 4 of the azimuth propeller 1E of the present embodiment, a rectifying plate 9 that can be rotated on the side surface of the rudder plate 4 is provided. In the present embodiment, the rectifying plate 8 is provided in a state in which the rectifying plate 8 is inclined downward from the bow side (upstream side) of the rudder plate 4 toward the stern side (downstream side). The eight rectifying plates 9 are arranged in two rows from the bow side of the rudder plate 4 toward the stern side, and four rectifying plates 9 are arranged in parallel in each row. Each of the rectifying plates 9' has a rotating shaft 9a - 21 - 201233589 extending substantially at the center in the longitudinal direction. The rotating shaft 9a penetrates the flow regulating plate 9 from the front side of the paper surface toward the side surface of the steering plate 4. As a result, the rectifying plate 9 can be rotated about the side surface of the rudder plate 4 around the rotating shaft 9a, and the inclination angle of the rectifying plate 9 in the extending direction can be made variable. Each of the rectifying plates 9 provided on the side of the rudder plate 4 as described above is rotatable independently of each other. Next, a description will be given of a control method when the azimuth thruster 1E is rotated. The azimuth propeller 1E that rotationally drives the propeller (propeller) 3 is rotated by a rotating device (not shown) provided in a ship (not shown). At this time, the flaps 7a, 7b, 7c, 7d, 7e, and 7f provided on the long side (upstream side long side) of the bow side of the rudder plate 4 for constituting the azimuth propeller 1E are independently bent (operated). Further, the plurality of flaps 5a, 5b, 5c, 5d, 5e, and 5f provided on the long side (upstream side long side) of the rudder side of the rudder plate 4 are each independently bent. The flow of water flowing after being guided to the propeller 3 is different depending on the number of rotations of the propeller 3 and the tidal current, and the number of rotations of the propeller 3 and the tidal current cause a complicated change in the flow of water. As described above, the complicated flow of water, as shown in Figs. 5(A) and 5(c), is directed from the downstream flow of the propeller 3 to the respective flaps 7a, 7b, 7c, 7d, 7e, 7f so that the flow direction changes. . The flow of water which changes the flow direction via the flaps 7a, 7b, 7c, 7d, 7e, 7f is the side which is guided to the rudder plate 4. The flow of water guided to the side of the rudder plate 4 is guided to the stern side along the rectifying flow direction along the rectifying plate 9 provided on the rudder plate 4. Here, the angle -22 - 201233589 of the rectifying plate 9' provided in the rudder plate 4 in the extending direction can be changed independently of each other. Therefore, the angle of each of the rectifying plates 9 can be changed in accordance with the flow direction of the water flow guided to the rudder plate 4 from the respective flaps 7a, 7b, 7c, 7d, 7e, 7f so that the water flow is guided to the stern side of the rudder plate. As described above, according to the azimuth thruster i E according to the present embodiment and the ship including the azimuth thruster 1E, the following effects can be obtained. The azimuth thruster 1E is provided with a rectifying plate (rectifying means) 9 which is rotatable on the side surface of the rudder plate 4. Therefore, it is possible to change the direction in which the flow regulating plate 9 extends in accordance with the change in the tidal current and the change in the flow of the rudder plate 4 caused by the change in the number of revolutions of the propeller (propeller) 3. Based on this, it is able to cope with complex water flows. Further, the inclination angle of the rectifying plate 9 provided on the side surface of the rudder plate 4 can be determined based on basic data obtained by prior experiments or the like, and can also be obtained from the navigation of the ship. In addition, the initial data can be properly corrected during the voyage. The present invention is not limited to the embodiments described above, and may be modified as appropriate without departing from the spirit and scope of the invention.
