【解決手段】船舶の推進力を生出すプロペラ翼3と方向を制御する舵板2との間に水流介装板5を取り付けることで、プロペラ後方に水流の障害物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ことが出来る船舶主舵板水流介装板構造を提供可能に構成した。
【選択図】図1[PROBLEMS] To reduce the propulsive force due to the turbulent flow that occurs between the water flow generated by a propeller and the main rudder plate and to suppress the vibration applied to the hull, and to improve the propulsive force and propulsion speed and improve fuel efficiency To provide a water flow board structure.
By attaching a water flow installation plate 5 between a propeller blade 3 that generates a propulsive force of a ship and a rudder plate 2 that controls the direction, the water flow is fixed even if there is an obstruction behind the propeller. It was constructed to be able to provide a ship main steering plate water flow plate structure that can prevent the generation of muddy flow with the water flow plate and change the energy of the water flow into propulsion without waste.

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
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
従来の技術としては、例えば、下記に示す様な先行例がある。
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
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
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.
