本考案は舶用可変ピツチプロペラの自動負荷制
御装置（以下自動負荷制御装置と言う）に関する
ものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic load control device (hereinafter referred to as automatic load control device) for a marine variable pitch propeller.
舶用可変ピツチプロペラの制御装置のうち自動
負荷制御装置と呼ばれるものがあり、これは主機
回転数と主機燃料投入量（即ち主機負荷）を一定
とし、プロペラのピツチを自動的に制御する方式
である。
Among the control devices for marine variable pitch propellers, there is something called an automatic load control device, which automatically controls the pitch of the propeller by keeping the main engine rotation speed and main engine fuel input (i.e. main engine load) constant. .
この方式によれば、主機の負荷と回転数の関係
を希望する状態に自由に選択出来るメリツトがあ
り、更に主機負荷が変動せず、安定した運航が出
来ると言う特徴がある。 This system has the advantage of being able to freely select the relationship between the main engine load and rotational speed as desired, and is also characterized by the fact that the main engine load does not fluctuate, allowing for stable operation.
第１図は従来の自動負荷制御装置の代表的な例
を示す。この装置では操縦ハンドル５を希望の位
置にセツトすれば燃料投入量設定信号R0、回転
数設定信号N0、翼角設定信号A0をそれぞれ発信
する。 FIG. 1 shows a typical example of a conventional automatic load control device. In this device, when the control handle 5 is set to a desired position, a fuel injection amount setting signal R 0 , a rotation speed setting signal N 0 , and a blade angle setting signal A 0 are respectively transmitted.
信号R0は主機１の燃料投入量設定手段６に入
つて例えばラツクを必要な位置にセツトする。一
方信号N0は翼角制御手段３に入つて実回転数信
号Ｎと比較して操縦ハンドル５より来る信号A0
を必要な翼角制御信号Ａに変換して翼角調節手段
２に与え、これによつて可変ピツチプロペラ４が
必要な翼角に調整される。 The signal R0 enters the fuel input amount setting means 6 of the main engine 1 to set, for example, the rack at the required position. On the other hand, the signal N 0 enters the blade angle control means 3 and is compared with the actual rotational speed signal N to obtain the signal A 0 coming from the control handle 5.
is converted into a necessary blade angle control signal A and applied to the blade angle adjusting means 2, whereby the variable pitch propeller 4 is adjusted to the required blade angle.
従来の方式によれば、主機のある負荷に相当す
る主機回転数と主機燃料投入量（通常は燃料ラツ
ク位置におきかえる）を主機の陸上運転等の結果
を参考にして予め設定しておき、操縦ハンドルに
よつてその負荷を選択すれば、予め設定されてい
た主機回転数と主機燃料ラツク位置が保たれる様
にプロペラピツチが自動的に制御されて、主機負
荷が目標通りに保たれる様になつている。しか
し、燃料ラツク位置が同じであつても、燃料の性
状が異なると実際に投入される燃料の量やエネル
ギーが変る為、同じ燃料ラツク位置にしても主機
の負荷が異つて来る事になる。 According to the conventional method, the main engine rotational speed and main engine fuel input amount (usually replaced with the fuel rack position) corresponding to a certain load on the main engine are set in advance with reference to the results of land operation of the main engine, etc. If you select the load using the handle, the propeller pitch will be automatically controlled to maintain the preset main engine rotation speed and main engine fuel rack position, and the main engine load will be maintained at the target. It's getting old. However, even if the fuel rack position is the same, if the properties of the fuel differ, the actual amount of fuel and energy input will change, so the load on the main engine will differ even if the fuel rack position is the same.
また、その外の主機に関連する運転条件が変る
事によつて、同じ回転数、同じ燃料ラツク位置で
も負荷が変つて来るので操縦ハンドルで主機の負
荷を設定出来ると言う自動負荷制御方式のメリツ
トの１つが失われる結果となる。 Additionally, as the operating conditions related to other main engines change, the load will change even at the same rotation speed and the same fuel rack position, so the automatic load control system has the advantage of being able to set the main engine load using the control handle. This results in the loss of one of the
一般に主機陸上運転では“Ａ”重油を、就航後
は“Ｃ”重油を使用する為、燃料油の性状が大き
く違う為、その都度調整が必要である。 Generally, "A" heavy oil is used when the main engine is operated on land, and "C" heavy oil is used after it enters service, so the properties of the fuel oil vary greatly, so adjustments must be made each time.
就航後も燃料の積地によつて性状が異なるため
一々面倒な調整や補正をしないとハンドルによる
負荷の設定値と実際の負荷が合致しない事にな
る。 Even after entering service, the properties of the fuel vary depending on the loading location, so unless you make some complicated adjustments and corrections, the load set by the handlebar will not match the actual load.
このように、従来の自動負荷制御装置によれ
ば、上記のように燃料の性状、主機の運転条件の
違いによつて操縦ハンドルによる設定と実際の主
機の負荷とに違いが生じ、それを修正する為にそ
の都度操縦ハンドルの面倒な調整をするか換算表
を与えるかをしなければならない。そして、実際
にはその都度繁雑な修正をする訳にはいかず勘を
頼りに適当な操作で我慢する外はなかつた。 According to the conventional automatic load control system, as mentioned above, differences in the fuel properties and main engine operating conditions cause differences between the setting on the control handle and the actual main engine load, and it is necessary to correct the difference. In order to do this, you have to make troublesome adjustments to the control handle or provide a conversion table each time. And in reality, I couldn't make complicated corrections each time, so I had no choice but to rely on my intuition and do the appropriate operations.

A 0 enters the blade angle control means 3. The correction calculation means 7 receives correction element setting or detection signals 15 to 15'''' from separately provided correction element setting means or detection means 8 to 8'''', and this signal causes the signal R 0

事になる。 According to this device, when the properties of the fuel, such as calorific value, viscosity, specific gravity, and specific heat, or the operating conditions of the main engine, such as supercharger inlet air temperature, main engine inlet air humidity, atmospheric pressure, etc., change, each numerical value is set as a correction element or By inputting the signal by the detection means 8 to 8'''' or by detecting it by a measuring instrument and automatically inputting the signal, the signal R0 is automatically corrected and becomes the signal R. As a result of the input to the fuel input amount setting means 6, the main engine will be operated with the load set by the control handle even if the properties of the fuel or operating conditions change.
