Description
【考案の詳細な説明】
本考案は船舶の改良に関するもので、船舶の推進性能の
向上を計るために船体の船尾部近傍にノズルを設けた船
舶において、船体の船尾部に舵板の支持張り出し部が無
い場合でもノズルを船体に強固に取り付けることができ
るようにしたものである。[Detailed description of the invention] This invention relates to the improvement of ships.In order to improve the propulsion performance of ships, a ship is equipped with a nozzle near the stern of the ship. This allows the nozzle to be firmly attached to the hull even if there is no part.
以下本考案を実施の一例を示す図面に基づいて説明する
。The present invention will be explained below based on drawings showing an example of implementation.
１は吃水下で船体２の船尾部近傍両舷において取り付け
られた正面形状リング状で側面形状略逆三角形状のノズ
ルである。Reference numeral 1 denotes a nozzle having a ring-like front face and a substantially inverted triangular side face, which is installed on both sides near the stern of the hull 2 under water.
３はプロペラ、４は舵板であり、この舵板４は上端のみ
船体２側に枢支されている。3 is a propeller, 4 is a rudder plate, and only the upper end of this rudder plate 4 is pivotally supported on the hull 2 side.
尚前記ノズル１の下端長さは強度上並びに取付作業上必
要な最小長さとし、この下端長さを１とした場合上端長
さは４〜６、特に６位いが良い。The length of the lower end of the nozzle 1 is the minimum length necessary for strength and installation work, and if this lower end length is 1, the length of the upper end is preferably 4 to 6, particularly about 6.
又ノズル１の取付位置はノズル後端面１ａがプロペラチ
ップよりも前方の位置乃至ノズル１がプロペラ３を覆う
位置迄の範囲内とすれば良い。The mounting position of the nozzle 1 may be within a range from a position where the nozzle rear end surface 1a is in front of the propeller tip to a position where the nozzle 1 covers the propeller 3.
ところで本考案ではノズル１の下端部１ｂは船体２の下
端に溶接固定したノズル支持材５の下面にボルト６、ナ
ット７により固定或いは溶接固定され、上端部１Ｃは後
端部が完全なリング状となって船体２の突出部２ａ下端
に溶接固定されいてると共にその部分よりも前端側は１
つ割りリング状となって船体２の両舷に溶接固定されて
いる。By the way, in the present invention, the lower end part 1b of the nozzle 1 is fixed or welded to the lower surface of the nozzle support member 5 which is welded and fixed to the lower end of the hull 2 with bolts 6 and nuts 7, and the rear end part 1C of the nozzle 1 has a complete ring shape. It is welded and fixed to the lower end of the protruding part 2a of the hull 2, and the front end side of that part is 1
It has a split ring shape and is welded and fixed to both sides of the hull 2.
前記ノズル支持材５の左右幅は船型に合わせて決められ
、又該ノズル支持材５の下面５ａは前記ノズル１の下端
部１ｂの内面に沿ってノズル軸心方向全長にわたるよう
に彎曲して形或されると共にノズル下端部１ｂの前端部
を挿入される凹入部５ｂを有している。The horizontal width of the nozzle support member 5 is determined according to the shape of the ship, and the lower surface 5a of the nozzle support member 5 is curved along the inner surface of the lower end portion 1b of the nozzle 1 over the entire length in the nozzle axial direction. It has a recessed part 5b into which the front end of the nozzle lower end 1b is inserted.

出し部が無い場合でもノズルを船体に安定良く強固に取
り付け得ると共に、ノズル支持材を針路安定性の助具と
して有効に活用できることから針路安定性の向上を図り
得る。As explained above, according to the present invention, the upper end of the nozzle is fixed to both sides of the hull, and the inner surface of the lower end of the nozzle is fixed to the lower end of the hull and has a surface along the inner surface of the lower end of the nozzle. Since the nozzle is in contact with the entire length in the axial direction, and the lower end of the nozzle is fitted into the recessed part of the nozzle support material and fixed, the nozzle can be stably attached to the hull even if there is no supporting protrusion of the rudder plate at the stern of the hull. Since it can be attached well and firmly and the nozzle support material can be effectively used as an aid for course stability, it is possible to improve course stability.
