Description
本考案は、太陽光発電による船舶推進システムおよび太陽光を動力源とする船舶に係り、特に、太陽光のみを動力源とした推進を可能とする、太陽光発電による船舶推進システムおよび太陽光を動力源とする船舶に関するものである。 The present invention relates to a ship propulsion system using solar power generation and a ship using solar power as a power source, and in particular, to a ship propulsion system using solar power generation and solar power that enables propulsion using only solar power as a power source. It relates to ships that use power.
温室効果ガスを排出することになる化石燃料の使用を低減ないしは廃止して、環境への負荷をできる限り軽減するため、太陽光、風力、地熱等の自然エネルギーを電源として利用すること、およびその研究開発は、従来から盛んに行われている。 In order to reduce or eliminate the use of fossil fuels that emit greenhouse gases, and to reduce the environmental burden as much as possible, use natural energy such as sunlight, wind power, and geothermal heat as a power source, and Research and development has been actively conducted.
船舶の分野では、たとえば後掲特許文献1のように、別途推進機構を備えている船体に太陽光から電気エネルギーを得る太陽光発電システムと、発電された電気エネルギーを用いて海水を電気分解し水素と酸素を得る電気分解手段と、得られた水素を貯蔵する水素貯蔵手段を備え、この水素を用いて発電する水素発電システムを提案されている。また、タンカー等でも、太陽光発電により船内の照明電源を一部賄うという例もある。このように太陽光発電については、船舶の分野においても技術的提案等がなされている。 In the field of ships, for example, as described in Patent Document 1 below, a solar power generation system that obtains electric energy from sunlight on a hull that has a separate propulsion mechanism, and seawater is electrolyzed using the generated electric energy. There has been proposed a hydrogen power generation system that includes an electrolysis unit that obtains hydrogen and oxygen and a hydrogen storage unit that stores the obtained hydrogen, and that generates electric power using the hydrogen. In some cases, tankers and the like partially cover the lighting power in the ship by solar power generation. Thus, regarding solar power generation, technical proposals and the like have been made in the field of ships.
しかしながら、船舶の推進動力を全て太陽光発電に頼ることとして実用化されている例は、未だ存在しない。もしそれが可能となると、温室効果ガス排出源である化石燃料の使用を廃止ないしは相当程度低減でき、環境負荷軽減にも大きく寄与することができる。 However, there is still no example that has been put into practical use by relying on solar power generation for all the propulsion power of ships. If this is possible, the use of fossil fuels, which are greenhouse gas emission sources, can be abolished or considerably reduced, which can greatly contribute to reducing environmental impact.
本考案が解決しようとする課題は、これら従来技術の問題点を踏まえ、太陽光のみを動力源とした推進を可能とする、太陽光発電による船舶推進システム、および太陽光を動力源とする船舶を提供することである。 The problems to be solved by the present invention are based on the problems of the prior art, and a ship propulsion system using photovoltaic power generation that enables propulsion using only sunlight as a power source, and a ship using sunlight as a power source.

It can be used as a backup, and can be used with more peace of mind for uses such as recreational fishing boats and general fishing boats.
以下、図面により本考案を詳細に説明する。
図1は、本考案の太陽光発電による船舶推進システムの基本構成を示す説明図である。図示するように本船舶推進システムは、太陽電池パネル1設置用の受け板部(図示せず)と、受け板部に設けられた太陽電池パネル1と、太陽電池パネル1に接続されるチャージコントローラー2と、チャージコントローラー2に接続されるバッテリー3と、チャージコントローラー2からさらに分岐接続される電動船外機4とからなることを、主たる構成とする。なお図中「直流24V」の表示は、後述する実施例に係るものであり、本考案がこれに限定されないことはいうまでもない。
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram showing a basic configuration of a ship propulsion system using photovoltaic power generation according to the present invention. As shown in the figure, the ship propulsion system includes a receiving plate portion (not shown) for installing the solar cell panel 1, a solar cell panel 1 provided on the receiving plate portion, and a charge controller connected to the solar cell panel 1. 2, a battery 3 connected to the charge controller 2, and an electric outboard motor 4 further branched from the charge controller 2. It should be noted that the display of “DC 24V” in the figure relates to an example described later, and it goes without saying that the present invention is not limited to this.
かかる構成により本船舶推進システムでは、受け板部に設けられた太陽電池パネル1において得られた太陽光エネルギーは光電変換され、チャージコントローラー2を介してバッテリー3に蓄電され、またチャージコントローラー2からさらに分岐接続されている電動船外機4に対する電源供給がなされ、電動船外機4は駆動され、本システムが設けられた(搭載された)船舶を推進せしめる。 With this configuration, in this marine vessel propulsion system, the solar energy obtained in the solar cell panel 1 provided on the receiving plate portion is photoelectrically converted and stored in the battery 3 via the charge controller 2, and further from the charge controller 2. Power is supplied to the branch-connected electric outboard motor 4, and the electric outboard motor 4 is driven to propel the ship on which the present system is installed (mounted).
本船舶推進システムに用いる太陽電池1の仕様は特に限定されないが、後述するように船舶船体の上方に設置することとなるため、できるだけ軽量であること、また性能ができるだけ高いものが望ましいことはいうまでもない。 Although the specification of the solar cell 1 used for this ship propulsion system is not specifically limited, since it will be installed above a ship hull so that it may mention later, it says that it should be as light as possible and have the highest possible performance. Not too long.
本船舶推進システムに用いるチャージコントローラー2、バッテリー3、および伝動船外機4についても、できるだけ軽量であること、また性能ができるだけ高いものが望ましいことには変わりがない。 The charge controller 2, the battery 3, and the transmission outboard motor 4 used in the ship propulsion system are also as light as possible and desirable as high as possible.
本船舶推進システムの受け板部は、特に、船体の平面構成の50%以上を占めるものとすることができる。本考案システムの動力源は太陽光であるため、太陽光の受光量をできる限り多くするためである。したがって、船体を上方から見た平面図(上面図)構成において、受け板部ができる限り広い面積を占められる構成がよい。 In particular, the receiving plate portion of the ship propulsion system may occupy 50% or more of the planar configuration of the hull. This is because the power source of the system of the present invention is sunlight, so that the amount of received sunlight is as large as possible. Therefore, in the plan view (top view) configuration of the hull viewed from above, a configuration in which the receiving plate portion occupies as wide an area as possible is preferable.
受け板部を設置する場所は、船体上で横方向に面積の取れるところとなる。つまり、船室の屋根部、ブリッジおよび甲板が考えられる。しかし甲板は、乗船者が通行できないように床板上に設置されていては不都合であるため、屋根のような構造を設け、その屋根部を受け板部とするのがよい。この点は、ブリッジに設ける場合も同様である。 The place where the receiving plate is installed is a place where the area can be taken in the horizontal direction on the hull. In other words, the roof, bridge and deck of the cabin can be considered. However, since it is inconvenient if the deck is installed on the floor so that the passenger cannot pass, it is preferable to provide a structure like a roof and use the roof as a receiving plate. This also applies to the case where the bridge is provided.
特に、船室の屋根部を受け板部として使える場合は、比較的大面積を確保できるため、それ単独でも、あるいは甲板やブリッジとの併用でも、本考案システム上、大いに都合がよい。たとえば屋形船のような船室の広い構造の船舶であれば、船室の屋根部は相当広い面積を有するため、本考案の太陽光発電による船舶推進システムの利用価値が一層高い。 In particular, when the roof portion of the cabin can be used as a receiving plate portion, a relatively large area can be secured, so that it is very convenient on the system of the present invention alone or in combination with a deck or a bridge. For example, in the case of a ship with a wide cabin such as a houseboat, the roof portion of the cabin has a considerably large area, so that the utility value of the ship propulsion system using solar power generation according to the present invention is higher.
以上説明した太陽光発電による船舶推進システムを設置(搭載)して、専ら太陽光のみを動力源とする船舶を構成することができる。一方、第二動力源としてガソリンエンジン等からなる通常の船外機をさらに備えた、いわばハイブリッド型としてもよい。この場合は、万一太陽光発電による推進に問題が起きた場合に第二動力源をバックアップとして用いることができ、遊漁船や一般の漁船といった用途においても、安心度が増す。 A ship propulsion system using solar power generation as described above can be installed (mounted) to configure a ship that exclusively uses sunlight as a power source. On the other hand, it may be a so-called hybrid type that further includes a normal outboard motor composed of a gasoline engine or the like as the second power source. In this case, the second power source can be used as a backup in the event that there is a problem with propulsion by solar power generation, and the level of security is increased even in applications such as recreational fishing boats and general fishing boats.
以下、本考案の実施例を説明するが、本考案がこの実施例に限定されるものではない。
