Description

本考案は、主機関による推進力と波力によって発生する油圧で駆動する油圧モーターと油圧モーターで駆動する発電機による電力で駆動する電動モーターとを補助的な推進力とするハイブリッド船舶に関するものである。 This invention relates to a hybrid ship that uses a hydraulic motor driven by the propulsive force of the main engine and hydraulic pressure generated by wave power, and an electric motor driven by electric power generated by a generator driven by the hydraulic motor, as auxiliary propulsion. be.

近年、地球温暖化問題及びエネルギー資源枯渇問題の顕在化に伴い、あらゆる分野において省エネルギー化と温室効果ガス排出量の削減が重要問題となっており、造船分野でも省エネルギーで温室効果ガス及び大気汚染物質を抑制した環境にやさしい船舶の実現が求められている。 In recent years, with the emergence of global warming and the depletion of energy resources, energy conservation and the reduction of greenhouse gas emissions have become important issues in all fields. There is a demand for the realization of an environmentally friendly ship that suppresses CO2 emissions.

環境にやさしい船舶として、主機関により発電された電力を蓄電装置に蓄電して、電力で駆動する電動モーターを補助的な推進力とするハイブリッド船舶が提案されている。 As an eco-friendly ship, a hybrid ship has been proposed in which electric power generated by a main engine is stored in a power storage device and an electric motor driven by the electric power is used as an auxiliary propulsion force.

また、帆走装備による風力推進力を補助的な推進力とするハイブリッド船舶や太陽光発電による電力で駆動する電動モーターを補助的な推進力とするハイブリッド船舶が提案されている。 In addition, a hybrid ship using wind propulsion by sailing equipment as an auxiliary propulsion force and a hybrid ship using an electric motor driven by electric power generated by solar power as an auxiliary propulsion force have been proposed.

従来の主機関により発電された電力により駆動する電動モーターを補助的な推進力とするハイブリッド船舶は常時主機関を作動させている必要があるが、帆走装置による風力推進力や太陽光発電による電力で駆動する電動モーターを補助的な推進力とするハイブリッド船舶は主機関を常時作動させる必要はない。しかし、風力利用の短所は装置が大がかりになることであり、太陽光利用の短所は一瞬の曇りにより急激に出力が低下することにあり、安定した補助推進力ではない。 A hybrid ship that uses an electric motor driven by electric power generated by the conventional main engine as auxiliary propulsion power needs to keep the main engine running all the time, but the wind propulsion power of the sailing device and the electric power generated by solar power generation A hybrid ship that uses an electric motor driven by a tee as auxiliary propulsion does not need to keep the main engine running all the time. However, the disadvantage of using wind power is that the equipment becomes large-scale, and the disadvantage of using solar power is that the output suddenly drops due to momentary cloudiness, so it is not a stable auxiliary propulsion force.

上記課題を解決するために、本考案の基本形は船舶の主動力である主機関の他に、波力により発生する油圧で駆動する油圧モーターと油圧モーターで駆動する発電機による電力で駆動する電動モーターとを補助動力とするハイブリッド船舶である。 In order to solve the above problems, the basic form of the present invention is a hydraulic motor driven by hydraulic pressure generated by wave power and an electric motor driven by electric power generated by a generator driven by the hydraulic motor, in addition to the main engine that is the main power of the ship.
