Description

本考案は、船舶のプロペラ３で発生する水流を滑らかに後方に押し出て、船舶の推進性能向上を図り省エネルギー化できるようにした船舶舵板水流介装板構造に関するものである。 The present invention relates to a ship steering plate water flow installation board structure that smoothly pushes a water flow generated by a propeller 3 of a ship backward to improve the propulsion performance of the ship and save energy.

下記の舵は、図６、図７、図８に図示するように主舵軸１よりも主舵板２の前部が突出する構造で構成されているのが特徴で、直進時はさほど影響はないが、図９の図９ａ、図９ｂに示すように右旋回、左旋回時プロペラから発生する水流を主舵前部で受けるため、濁流が発生して推進性能を損失させる原因となっていた。又、図6、図7中の符号8は舵柄を示す。 The following rudder is characterized by a structure in which the front portion of the main rudder plate 2 protrudes from the main rudder shaft 1 as shown in FIGS. 6, 7, and 8. However, as shown in FIGS. 9a and 9b in FIG. 9, since the water flow generated from the propeller during the right turn and the left turn is received by the main rudder front part, a muddy flow is generated and the propulsion performance is lost. It was. Moreover, the code | symbol 8 in FIG. 6, FIG. 7 shows a steering handle.

従来から用いられてきた流線型の舵は、直進時はプロペラ中心と舵軸中心がずれること無く、プロペラから発生する水流が後方に押し出され問題は無いが、主舵板が、左右の旋回時には、プロペラ中心から主舵軸の中心が、主舵先端部分が左右にぶれる為、プロペラから発生した水流が主舵先端部に当り、濁流となり推進性能を妨げ舵抵抗が大きくなってしまうという問題があり、船体の横滑りや振動の要因となり、船の推進抵抗が大きくなり、燃料の膨大な損出にもなる。 The streamline type rudder that has been used in the past has no problem when the propeller center and the rudder shaft center do not shift when going straight, and the water flow generated from the propeller is pushed backward, but there is no problem, but the main rudder plate is when turning left and right, Since the center of the main rudder shaft from the center of the propeller sways to the left and right, the water flow generated from the propeller hits the main rudder tip, resulting in muddy flow, impeding propulsion performance and increasing the rudder resistance. As a result, hull skidding and vibration are caused, and the propulsion resistance of the ship increases, resulting in a huge loss of fuel.

船底の推進用プロペラの後方位置に設けられる主舵板と、前記プロペラの間に、固定型水流介装板を配置し、前記水流介装板の水平断面形状が流線型に形成されると共に、前記水流介装板の主舵板との摺動面は、前記主舵板の舵軸を覆う構造に形成されてなる船舶舵板水流介装板構造としたことにより、水流の濁流発生を防止しプロペラの回転で発生した水流を無駄なく推進力にすることができる船舶舵板水流介装板構造を提供するものである。 A fixed water flow installation plate is disposed between a main rudder plate provided at a rear position of a propeller for propulsion on the bottom of the ship and the propeller, and a horizontal sectional shape of the water flow installation plate is formed in a streamline shape, and The sliding surface of the water flow plate with the main rudder plate is a ship rudder plate water flow plate structure formed to cover the rudder shaft of the main rudder plate, thereby preventing the occurrence of turbid flow of water flow. It is intended to provide a ship rudder plate water flow installation plate structure that can make a water flow generated by rotation of a propeller into a propulsive force without waste.

本考案は、船舶の推進力を生出すプロペラ翼と方向を制御する主舵板との間に、水流介装板を配置した（取付ける）ことでプロペラ後方に水流の障害があっても固定された水流介装板で濁流の発生を防止し、水流のエネルギーを無駄なく推進力に変える事ができ又燃費の省エネ化も出来るようになった。 In the present invention, by arranging (attaching) a water flow installation plate between the propeller blade that generates the propulsion power of the ship and the main rudder plate that controls the direction, it is fixed even if there is a water flow failure behind the propeller. Moreover, the generation of muddy flow can be prevented with the water flow mounting plate, and the energy of the water flow can be changed to propulsion without waste, and energy saving can be achieved.

また、濁流が発生しないので船体の横滑りや振動も減り快適な操船が出来るようになった。 In addition, since no turbidity is generated, the sides of the hull and vibrations are reduced, and the ship can be operated comfortably.

以下、本考案に係る水流介装板につき、図１〜図５ｂを参照して以下説明する。 Hereinafter, the water flow installation board according to the present invention will be described with reference to FIGS.

図１に図示するように、船体６の甲板に舵軸固定管一体の水流介装板５を組み込み、主舵軸１と水流介装板５は、図３ａ〜図３ｅの断面に図示するように隙間を一定に保持する構造にした。図２〜図４に図示の水流介装板５は主舵軸１の側面から前部を覆う事の出来る形状と、先端部を細く流線型に模りすることで水流の抵抗を少なくした。水流介装板５の縦方向の長さは、図２に図示の主舵板２と同じ長さにして、主舵板２の前部を図３ａ〜図３ｅに図示の如く、主舵板軸１の側面と前部を覆うようにし、水流が水流介装板5に直に当りわずかな濁流も防止する構造とした。 As shown in FIG. 1, a water flow installation plate 5 integrated with a rudder shaft fixed pipe is incorporated in a deck of a hull 6, and the main rudder shaft 1 and the water flow installation plate 5 are illustrated in the cross sections of FIGS. 3 a to 3 e. The gap is kept constant. 2 to 4, the water flow resistance plate 5 has a shape that can cover the front portion from the side surface of the main rudder shaft 1 and the tip portion is thinly streamlined to reduce water flow resistance. The longitudinal length of the water flow installation plate 5 is the same as that of the main rudder plate 2 shown in FIG. 2, and the front portion of the main rudder plate 2 is as shown in FIGS. 3a to 3e. The side surface and the front part of the shaft 1 are covered so that the water flow directly hits the water flow plate 5 to prevent a slight turbid flow.

図２の舵軸固定管一体の水流介装板５に主舵軸１、２を差し込む構造に構成し船体６に固定した。この構造により主舵軸１と水流介装板５が二重構造に成ることで強度も増した。また図５、図５ａ、図５ｂに図示するように滑らかな水流が発生した。本実施例では、舵軸固定管一体の水流介装板5としたが、取付部のスペースなどの事情によっては、固定型水流介装板を図示省略の水流介装板軸固定管に組込み一体型にしてもよい。 The main rudder shafts 1 and 2 are inserted into the water flow intermediate plate 5 integrated with the rudder shaft fixed pipe in FIG. 2 and fixed to the hull 6. With this structure, the main rudder shaft 1 and the water flow installation plate 5 have a double structure, so that the strength is also increased. Also, a smooth water flow was generated as shown in FIGS. In this embodiment, the water flow guide plate 5 is integrated with the rudder shaft fixed pipe. However, depending on circumstances such as the space of the mounting portion, the fixed water flow guide plate is incorporated into the water flow guide plate shaft fixed pipe (not shown). It may be a figure.

複数の舵メーカによっては、主舵板軸の長さが主舵板の中間部まである物ものや様々な形状があるので、其の形状に合わせ隙間を小さくする構造が最良の形態である。 Depending on a plurality of rudder manufacturers, the main rudder plate shaft has an object having a length up to the middle part of the main rudder plate and various shapes. Therefore, the structure in which the gap is reduced in accordance with the shape is the best mode.
