Description

本発明は、船舶の舵角を検出する舵角指示手段と、船舶が走行する速力を検出する速力検出手段と、船舶の喫水データを検出する喫水検出手段と備えた船舶の推進制御装置に関する。   The present invention relates to a boat propulsion control device including a rudder angle instruction unit that detects a rudder angle of a vessel, a speed detection unit that detects a speed at which the vessel travels, and a draft detection unit that detects draft data of the vessel.

船舶が旋回する場合、一端側のプロペラのトルクが増大するので、主プロペラを駆動する主プロペラ駆動主機の回転数が低下する。この場合、船舶には推進力の他に、軸に直角な面内の横力が作用する。
この横力は、図１６（Ａ）に示されるように、旋回時の横力は直進時に比べて大幅に増加する。かかる横力が増加すると、図１６（Ｂ）に示されるように、船舶のプロペラ軸２４が曲げられて該プロペラ軸２４と船尾管軸受２３とが接触して軸の焼き付きを生じて、航行不能になる事故が発生する可能性がある。２４´は中間軸受である。 When the ship turns, the torque of the propeller on one end side increases, so the rotational speed of the main propeller driving main machine that drives the main propeller decreases. In this case, in addition to the propulsive force, a lateral force in a plane perpendicular to the axis acts on the ship.
As shown in FIG. 16 (A), this lateral force is significantly increased when turning, compared to when traveling straight. When the lateral force increases, as shown in FIG. 16 (B), the propeller shaft 24 of the ship is bent and the propeller shaft 24 and the stern tube bearing 23 come into contact with each other to cause seizure of the shaft. An accident may occur. Reference numeral 24 'denotes an intermediate bearing.

かかる横力を軽減するため、特許文献１（特開２００６−１３７３３４号公報）においては、舵角を検出する舵角指示器と、船舶の走行時の速力を検出する速力検出器と、主プロペラを駆動する主プロペラ駆動主機とを備え、前記舵角指示器、速力検出器、主プロペラ駆動主機の各検出手段に基づいて、主プロペラ軸に係る横力を算出し、横力が所望値以内に収まる推進動力を回転指示器に収めるように構成されている。   In order to reduce such lateral force, in Patent Document 1 (Japanese Patent Laid-Open No. 2006-137334), a rudder angle indicator that detects a rudder angle, a speed detector that detects a speed when a ship travels, and a main propeller. A main propeller drive main machine for driving the main propeller shaft, and based on the detection means of the rudder angle indicator, speed detector, and main propeller drive main machine, the lateral force on the main propeller shaft is calculated, and the lateral force is within a desired value. The propulsion power that falls within the range is stored in the rotation indicator.

本発明によれば、船舶の舵角を検出する舵角指示手段と、船舶が走行する速力を検出する速力検出手段との制御に加えて、喫水検出手段によって船舶の喫水データを検出してこの喫水データを加えるので、これらの各検出手段からの検出値に基づき、かかる検出値と横力との関係を用いて主機の回転数を制御することができることとなり、従って特に旋回時に大きく変わる喫水データを盛り込んで主機の回転数を制御するので、旋回開始からの時間に対応して主機の回転数を低下させて、プロペラ軸の横力を減少させることができる。   According to the present invention, in addition to the control of the steering angle instruction means for detecting the steering angle of the ship and the speed detection means for detecting the speed at which the ship travels, the draft detection means detects the draft data of the ship. Since draft data is added, the rotation speed of the main engine can be controlled using the relationship between the detected value and the lateral force based on the detected value from each of these detecting means. Since the rotational speed of the main machine is controlled by incorporating, the rotational speed of the main machine can be reduced corresponding to the time from the start of turning, and the lateral force of the propeller shaft can be reduced.

かかる効果は、左舷主機と右舷主機とを備えた船舶、主プロペラに対向して設置されポッドモータにより船舶に推進力を付与するポッド推進器を備えた船舶、ＣＰＰ翼角制御手段により制御される可変ピッチプロペラを備えた船舶、船尾管軸受に軸受と軸との間隙を計測するギャップセンサーを備えた船舶等の各種の船舶の横力の抑制装置に広く適用できる。   Such an effect is controlled by a ship provided with a port main engine and a starboard main machine, a ship provided with a pod propulsion device installed opposite to the main propeller and imparting propulsive force to the ship by a pod motor, and CPP blade angle control means. The present invention can be widely applied to a lateral force suppressing device for various ships such as a ship having a variable pitch propeller and a ship having a stern tube bearing and a gap sensor for measuring a gap between the bearing and the shaft.

In the rotation indicator 4, the relationship between the detection value and the lateral force is set based on the detection value from each of the detection means, and the lateral force increases as the rudder angle increases, and the speed is high. The greater the lateral force, the greater the increase. Also, the speed is set to decrease as the draft increases.

そして、前記回転指示器４においては、主機５の回転数を予め設定された回転数に保持し、且つ前記舵角指示器から舵角を検出値、速力計からの速力検出値、及び喫水計１からの喫水データの検出値を、前記舵角の設定値、速力の設定値、及び喫水データの設定値等と対比させて、横力を減少するように制御する。
図２に示すように、Ａが前記のような制御を行った横力の図、Ｂが前記のような制御を行なわない横力の図で、前記制御を行うことにより横力を低減できる。 And in the rotation indicator 4, the rotation speed of the main machine 5 is held at a preset rotation speed, and the steering angle is detected from the steering angle indicator, the speed detection value from the dynamometer, and the draft meter. The detected value of the draft data from 1 is compared with the set value of the steering angle, the set value of the speed, the set value of the draft data, and the like, and is controlled so as to reduce the lateral force.
As shown in FIG. 2, A is a lateral force diagram in which the above control is performed, and B is a lateral force diagram in which the above control is not performed. The lateral force can be reduced by performing the control.

かかる第１実施例によれば、船舶の舵角を検出する舵角指示器２と、船舶が走行する速力を検出する速力計３との制御に加えて、喫水計１によって船舶の喫水データを検出してこの喫水データを加えるので、これらの各検出手段からの検出値に基づきかかる検出値と横力との関係を用いて主機５の回転数を制御することができることとなり、従って特に旋回時に大きく変わる喫水データを盛り込んで主機５の回転数を制御するので、旋回開始からの時間に対応して主機５の回転数を低下させて、プロペラ軸２４の横力を減少させることができる。   According to the first embodiment, in addition to the control of the rudder angle indicator 2 that detects the rudder angle of the ship and the speedometer 3 that detects the speed at which the ship travels, the draft data of the ship is obtained by the draft meter 1. Since this draft data is detected and added, the rotational speed of the main engine 5 can be controlled using the relationship between the detected value and the lateral force based on the detected value from each of these detecting means. Since drought data that varies greatly is included and the rotation speed of the main machine 5 is controlled, the rotation speed of the main machine 5 can be reduced corresponding to the time from the start of turning, and the lateral force of the propeller shaft 24 can be reduced.
