Description
本発明は、船舶の電動化に関する方式であって、従来の船舶をより静粛で柔軟に運航可能にした駆動方式に関するものである。 The present invention relates to a method for driving a ship, and relates to a drive system that enables a conventional ship to be operated more quietly and flexibly.
電動モータはその制御が内燃機関に比べ容易であり、排ガスを出さず、静粛な駆動が行える利点をもっている。電動モータの特長を生かして、従来から船舶において、電気モータを用いたハイブリッド駆動方式が用いられてきた。しかし、このような方式は、単純に使用中の船舶に対して改造を施すことが困難であるほか、主に大型船舶における柔軟な駆動を獲得するために行われてきたものである。この方式のものとしては、ディーゼル機関や、ガスタービンで発電機を駆動し、その電力を使った電動モータ駆動による大型旅客船や軍艦、砕氷船などがある(シリーズハイブリッド方式)。また、電動モータと内燃機関を両方、あるいは単独で切り替え使用できるギヤシステムを使用したパラレルハイブリッド式の電動船舶がある。一方、電動モータを用いて電気エネルギーだけで駆動する電動船は古い歴史を持っており、主に小型船舶として利用されてきた。しかし、この方式では、搭載できる電池エネルギーの制限から、大型船舶や長期間の航行は困難であった。すなわち、電動モータの静粛性を生かした航行が可能である特徴があるにも拘わらず、その普及を妨げてきたのは、電池の性能と、単純な船舶の改造方式が存在しなかったことによる。そこでこれらに比べ簡単で電動化が可能になる方式の出現が望まれていた。 The electric motor is easier to control than the internal combustion engine, and has an advantage that it can be driven silently without emitting exhaust gas. Taking advantage of the electric motor, a hybrid drive system using an electric motor has been used in ships. However, it is difficult to simply modify a ship that is in use, and such a method has been performed mainly for obtaining a flexible drive in a large ship. This type includes large passenger ships, warships, and icebreakers that use a diesel engine or a gas turbine to drive a generator and drive an electric motor that uses that power (series hybrid system). In addition, there is a parallel hybrid type electric ship using a gear system that can be used by switching both the electric motor and the internal combustion engine or independently. On the other hand, an electric ship driven by electric energy using an electric motor has an old history and has been mainly used as a small ship. However, this method has been difficult for large ships and long-term navigation due to the limitation of battery energy that can be installed. In other words, despite the fact that it is possible to navigate using the quietness of the electric motor, it has been hindered by the battery performance and the lack of a simple ship remodeling method. . Therefore, there has been a demand for the emergence of a method that is simpler and can be electrified than these.
内燃機関と電動モータとを駆動源として備えたパラレルハイブリッド型の船舶用船外機としては、例えば特許文献１に記載されているように、内燃機関に接続し、その出力をプロペラに伝達する第１の出力軸と、電動モータに接続し、その出力をプロペラに伝達する第２の出力軸とを備えると共に、第１の出力軸と第２の出力軸がそのまま連結される。また、特許文献２には、内燃機関と電動モータとをプロペラの駆動源として備えると共に、内燃機関に接続し、その出力をプロペラに伝達する第１の出力軸と、電動モータに接続し、その電動モータの出力をプロペラに伝達する第２の出力軸とを共軸に配置することを記載されている。 As a parallel hybrid marine outboard motor equipped with an internal combustion engine and an electric motor as drive sources, for example, as described in Patent Document 1, it is connected to an internal combustion engine and the output is transmitted to a propeller. The first output shaft and a second output shaft that is connected to the electric motor and transmits the output to the propeller are connected, and the first output shaft and the second output shaft are connected as they are. Patent Document 2 includes an internal combustion engine and an electric motor as a propeller drive source, and is connected to the internal combustion engine and its output is transmitted to the propeller, and is connected to the electric motor. It is described that the second output shaft that transmits the output of the electric motor to the propeller is disposed on the same axis.
内燃機関は、エンジンの回転可能範囲が電動モータに比べて狭く、高速走行と超低速走行を同時に満たすことは困難であった。一方、電動モータは、制御の柔軟性と静粛性があるにも拘わらず、電池の搭載可能容量が不足し、十分な距離の運航や高速運転が困難であった。それらを解決することが課題になってきた。そこで、内燃機関の駆動及び発電能力を生かし、電動モータによる駆動も可能にする方式が必要とされてきた。 The internal combustion engine has a narrower range of rotation of the engine than an electric motor, and it is difficult to satisfy both high speed traveling and ultra-low speed traveling at the same time. On the other hand, despite the flexibility and quietness of the control, the electric motor has insufficient battery mountable capacity, making it difficult to operate a sufficient distance and operate at high speed. Solving them has become a challenge. Therefore, there has been a need for a system that makes use of the drive and power generation capability of the internal combustion engine and that can also be driven by an electric motor.
その解決法としては、従来ある船舶の内燃機関とプロペラで構成される船内機、あるいは船内外機システムにおいて、内燃機関とプロペラをつなぐプロペラシャフトの一部に電動モータを入れた方式である。 As a solution to this problem, there is a method in which an electric motor is inserted in a part of a propeller shaft connecting an internal combustion engine and a propeller in an inboard motor or an inboard / outboard motor system configured with an internal combustion engine and a propeller of a conventional ship.
内燃機関とプロペラをつなぐプロペラシャフトの一部に電動モータを組み入れる船舶改造は、比較的簡単な手法であり、新艇以外にも、従来運航されている船舶に対し、ほとんど改造することなく、電動モータによる優れた制御性などの特長を生かした船舶にすることも可能になる。 Vessel remodeling that incorporates an electric motor into the part of the propeller shaft that connects the internal combustion engine and the propeller is a relatively simple technique. It is also possible to make a ship that makes use of features such as excellent controllability by a motor.
以下に、本発明の実施の形態を説明する。 Hereinafter, embodiments of the present invention will be described.
本発明における船内機での駆動方式１（図１）では、船体８の船内に取り付けられた内燃機関１とプロペラ６間に電動モータ４をつけたものである。内燃機関１はクラッチ３を持っており、駆動軸２を介して電動モータ４とつながっている。クラッチ９は電動モータ４とプロペラ６間に取り付ける。これは必要な場合に用いる。ユニバーサルジョイント１０はプロペラシャフト５の軸の角度を調整するため、従来から使われているものである。内燃機関１はクラッチ３、クラッチ９（もし取り付けた場合）を接続すれば、電動モータ４の駆動力の有無に拘わらず、直接プロペラ６を駆動することが可能である。プロペラ６は、内燃機関１あるいは電動モータ４の動力によって、ユニバーサルジョイント１０とプロペラシャフト５を介して駆動される。 In the drive system 1 (FIG. 1) for an inboard motor according to the present invention, an electric motor 4 is attached between the internal combustion engine 1 and the propeller 6 mounted in the ship 8. The internal combustion engine 1 has a clutch 3 and is connected to an electric motor 4 via a drive shaft 2. The clutch 9 is attached between the electric motor 4 and the propeller 6. This is used when necessary. The universal joint 10 is conventionally used to adjust the angle of the propeller shaft 5. If the internal combustion engine 1 is connected to the clutch 3 and the clutch 9 (if attached), the propeller 6 can be directly driven regardless of the driving force of the electric motor 4. The propeller 6 is driven through the universal joint 10 and the propeller shaft 5 by the power of the internal combustion engine 1 or the electric motor 4.
図１に示した駆動方式において説明する。クラッチ９は使用しなくとも良い。内燃機関１が回転し、クラッチ３とクラッチ９がつながっていれば、電動モータ４は空転して内燃機関１によるプロペラ６駆動が出来る。電動モータ４を同時に駆動すれば、両者のトルクの合計が駆動力を発生する。クラッチ３を切ると、電動モータ４だけの駆動になり静粛で、超低速まで柔軟な運転が可能になる。その時、内燃機関１に取り付けられた発電機を用いることにより、直接、電動モータ４の駆動が可能である。また、内燃機関１に取り付けられた発電機により、蓄電池を充電しておき、このエネルギーにより、この電動モータ４の駆動が可能である。あるいは、この電動モータ４を発電機として使用し、航行中に、電池の充電を行うことも可能である。駆動方式１（図１）では、電気モータ４とプロペラ６間にクラッチ９を取り付けることによって、船舶が静止中においても、内燃機関からの動力で発電をすることが出来る。 The driving method shown in FIG. 1 will be described. The clutch 9 may not be used. If the internal combustion engine 1 rotates and the clutch 3 and the clutch 9 are connected, the electric motor 4 rotates idly and the propeller 6 can be driven by the internal combustion engine 1. If the electric motor 4 is driven at the same time, the sum of both torques generates a driving force. When the clutch 3 is disengaged, only the electric motor 4 is driven, and the operation can be performed quietly and flexibly up to an extremely low speed. At that time, the electric motor 4 can be directly driven by using a generator attached to the internal combustion engine 1. Further, a storage battery is charged by a generator attached to the internal combustion engine 1, and this electric motor 4 can be driven by this energy. Alternatively, the electric motor 4 can be used as a generator to charge the battery during navigation. In the drive system 1 (FIG. 1), the clutch 9 is attached between the electric motor 4 and the propeller 6, so that power can be generated by the power from the internal combustion engine even when the ship is stationary.
本発明における船内外機による駆動方式２（図２）では、船内外機において、船体８の船内にある内燃機関１と、船外にあるプロペラ６のあるドライブユニット１１間に電動モータ４を取り付けた方式である。 In the driving system 2 (FIG. 2) using the inboard / outboard motor in the present invention, the electric motor 4 is attached between the internal combustion engine 1 in the hull 8 and the drive unit 11 having the propeller 6 outside the ship in the inboard / outboard motor. It is a method.
駆動方式２（図２）では、船体８の船内にある内燃機関１と船外にあるプロペラ６のあるドライブユニット１１間に電動モータ４を取り付けているが、クラッチ３が接続されれば、電動モータ４の駆動の有無に拘わらず、内燃機関１によりプロペラシャフト５を介して、プロペラ６が駆動できる。クラッチ３を非接続にすれば、電動モータ４のみによる柔軟で静粛な運転が可能になる。電動モータ４は、内燃機関１による動力で航行中に電動モータ４駆動用の蓄電池を充電することも可能であるし、内燃機関１そのものにつながれた別の発電機で、電動モータ４駆動用の蓄電池を充電することも可能である。電動モータ４とプロペラ６間に更にもう１個のクラッチを取り付けるか、あるいはプロペラ６のあるドライブユニット１１自体に別途クラッチを内蔵することによって、船舶が静止中においても、内燃機関１からの動力で発電をすることが出来るのは、駆動方式１（図１）と同様である。 In the drive system 2 (FIG. 2), the electric motor 4 is attached between the internal combustion engine 1 in the hull 8 and the drive unit 11 having the propeller 6 outside the ship, but if the clutch 3 is connected, the electric motor The propeller 6 can be driven by the internal combustion engine 1 via the propeller shaft 5 regardless of whether or not 4 is driven. If the clutch 3 is disconnected, a flexible and quiet operation using only the electric motor 4 becomes possible. The electric motor 4 can be charged with a storage battery for driving the electric motor 4 while navigating with the power of the internal combustion engine 1, or is another generator connected to the internal combustion engine 1 itself, for driving the electric motor 4. It is also possible to charge the storage battery. By installing another clutch between the electric motor 4 and the propeller 6 or by separately incorporating a clutch in the drive unit 11 itself with the propeller 6, power is generated by the power from the internal combustion engine 1 even when the ship is stationary. This can be done in the same manner as in the driving method 1 (FIG. 1).
本発明によれば、電動モータを船内機か船内外機の内燃機関とプロペラ間の一軸に取り付けつけることによって、船舶の静粛で広範囲の速度における柔軟な制御を可能にすることができる。 According to the present invention, by attaching the electric motor to one shaft between the internal combustion engine of the inboard motor or the inboard / outboard motor and the propeller, the ship can be quietly controlled in a wide range of speeds.
