Description

本考案は近海水路や湖上或いはダムなどで運航される両頭船に関する。   The present invention relates to a double-headed ship operated on a near seaway, a lake or a dam.

貨客などの積載量を増加し、安定走行を可能ならしめる双胴船や三胴船などは、本考案者により既に提案したところである。
実用新案登録第3069138号
Catamarans and trimares, which increase the loading capacity of cargo passengers and enable stable running, have already been proposed by the present inventors.
Utility model registration No. 3069138

従来のプロペラ推進器による運航は、これが船底に突起物となるため、比較的浅海での航行では浮遊物や岩礁などでプロペラ翼破損の問題がある。
本考案は貨客などの積載量を増加し、且つ安定走行を可能ならしめた双胴船や三胴船などに対し、その水深が比較的浅い場合であっても障害なく運航を可能なさしめんとするものである。
In the case of navigation using a conventional propeller propulsion device, this becomes a protrusion on the bottom of the ship.
The present invention increases the loading capacity of cargo passengers, etc., and enables catastrophic operations such as catamarans and trimares that are capable of stable operation even when the water depth is relatively shallow. It is what.

本考案は、単胴となした船体の長さ方向の左右両舷側から外方へ向かって一定長さ突出させた箇所に対し、上記船体よりは比較的小容積の縦長浮用空胴体を船体と同方向へ並設し、該浮用空胴体は船体と同様にその下面部が水中へ浸沈させる構成で、且つ船体の前方部と後方部の2箇所にポンプジェットを装備させ、上記夫々れのポンプジェットの運転により、運航させるものとなした三胴船体を特徴とする。
また、双胴となした船体の長さ方向の中央に対し、上記船体よりは比較的小容積の縦長浮用空胴体を設け、該浮用空胴体の下面部は水中へ浸沈させる構成で、且つ双胴の各前方部と後方部の2箇所にポンプジェットを装備させ、上記夫々れのポンプジェットの運転により運航させるものとなした三胴船体を特徴とする。
而して、上記に於けるポンプジェットは船体の夫々れ船底下面部に対し取付けるようになすのである。
In the present invention, a vertical floating cavity with a relatively smaller volume than the above hull is provided for the part that protrudes a fixed length outward from the left and right sides in the length direction of the hull that has become a single hull. In parallel with the hull, the floating cavity has a structure in which the lower surface of the hull is submerged in water, and is equipped with pump jets at two locations on the front and rear of the hull. It features a three-hull hull that is operated by the operation of these pump jets.
In addition, a vertically long floating cavity having a relatively smaller volume than the above hull is provided at the center in the longitudinal direction of the hull that is a catamaran, and the bottom surface of the floating cavity is submerged in water. In addition, it is characterized by a three-hull hull that is equipped with pump jets at two locations, the front part and the rear part, of the catamaran and operated by the operation of the respective pump jets.
Thus, the above-described pump jet is attached to the bottom surface of the bottom of the hull.

本考案によれば双胴船や三胴船の積載量を増加させた貨客船や作業船を、水深が比較的浅い場合であっても何ら障害を生じさせない効率の良い運航を可能ならしめるのであり、とりわけ遊覧船や作業船などの使用で優れたものとなる。   According to the present invention, cargo passenger ships and work ships with increased catamaran and trimarine loading capacity can be operated efficiently without causing any obstacles even when the water depth is relatively shallow. In particular, it will be excellent in the use of pleasure boats and work boats.

図1は本考案に係る三胴船体を特徴とする両頭船の側面図、図2は上記の平面図、図3は正面図である。図示例では単胴となした船体1の長さ方向の左右両舷側から外方へ向かって一定長さ突出させた箇所に対し、上記船体よりは比較的小容積の縦長浮用空胴体2,2を船体1と同方向へ並設させるのであり、3,3はその鉄骨材による連結材である。このさい、浮用空胴体2,2は船体1と同様にその下面部が水中へ浸沈されるものとなされる。なお、4は両者間を跨ぐように構成される甲板であって、単胴船のものより大きな甲板が形成されるのであり、該甲板上には客室や荷役倉庫5などの目的に応ずる各種設備が装設されるものとなる。   1 is a side view of a double-headed ship characterized by a trihull hull according to the present invention, FIG. 2 is a plan view of the above, and FIG. 3 is a front view. In the example shown in the figure, a vertically floating cavity 2, which has a relatively smaller volume than the above-mentioned hull, with respect to a location where the hull 1 formed as a single hull protrudes a certain length outward from the left and right sides in the length direction. 2 are juxtaposed in the same direction as the hull 1, and 3 and 3 are connecting members made of steel frames. At this time, the floating cavities 2 and 2 are submerged in water in the same manner as the hull 1. In addition, 4 is a deck comprised so that both may be straddled, Comprising: A deck larger than the thing of a monohull ship is formed, Various equipment according to the objectives, such as a guest room and cargo handling warehouse 5, on this deck Will be installed.

6,6はポンプジェットであって、船体1の前方部aと後方部bの下面部に対し、装備させてなる。ここに各ポンプジェット6,6はディーゼルエンジン7,7の駆動によりインペラが回動され、その底面部から水を吸い込むことにより必要な推進力が得られるようにするのである。図4は上記の部分作用説明図であり、即ち(イ)でインペラ6aはインテークファンネルを通して底部から水を吸い込み、次に吸い込まれた水は(ロ)に示す如くインペラによって強制的に運動エネルギーとしてディフューザ6bに送り込まれ、次に(ハ)に示す如く水の運動エネルギーはディフューザー部分から圧力ケーシング6c内に送られ、而して(ニ)に示す如く圧力エネルギーに変換される。斯くして圧力ケーシング内の水はボトムプレートの吐出ノズル6dから斜め下方に噴出されるのであり、これにより船体1に必要な推進力が発揮されるものとなる。なお、8はランプドアである。   Reference numerals 6 and 6 denote pump jets which are provided on the lower surface of the front part a and the rear part b of the hull 1. Here, the impellers of the pump jets 6 and 6 are rotated by driving the diesel engines 7 and 7, and the necessary propulsive force is obtained by sucking water from the bottom surface. FIG. 4 is an explanatory view of the above partial action. That is, in (a), the impeller 6a sucks water from the bottom through the intake funnel, and the sucked water is forcibly converted into kinetic energy by the impeller as shown in (b). Then, the kinetic energy of water is sent from the diffuser portion into the pressure casing 6c and converted into pressure energy as shown in (d). Thus, the water in the pressure casing is ejected obliquely downward from the discharge nozzle 6d of the bottom plate, and thereby the propulsive force necessary for the hull 1 is exhibited. Reference numeral 8 denotes a lamp door.

上記実施例では前方部と後方部のポンプジェット6,6に夫々れディーゼルエンジン7,7を取付けて駆動されるものについて説明したが、1つのディーゼルエンジンで適宜切換えて使用する設計が可能である。   In the above embodiment, the description has been given of the diesel engine 7 and 7 that are driven by the front and rear pump jets 6 and 6, respectively. .

上記は船体1の左右外方へ該船体1より比較的小容積の浮用空胴体を設けた三胴船体の例であるが、本考案は図5及び図6の正面図及び平面図で示す如く双胴船の船体1’,1’の中央に対し、これら船体容積より比較的小容積となした浮用空胴体2’を設けるようになした構成のものであっても差し支えない。上記構成で、浮用空胴体2’の下方底面部が浸沈されることは前例と変わりない。なお、図面で3’は連結部材、6’はポンプジェットであって、夫々れ双胴となした船体2’,2’の前方部と、後方部にディーゼルエンジン7’を介して設けたものとなしてある。   The above is an example of a three-hull hull in which a floating cavity having a relatively smaller volume than that of the hull 1 is provided on the left and right sides of the hull 1. The present invention is shown in front and plan views of FIGS. In this way, the structure may be such that a floating cavity 2 'having a relatively smaller volume than the hull volume is provided in the center of the hulls 1' and 1 'of the catamaran. With the above configuration, the lower bottom surface portion of the floating cavity 2 'is submerged as in the previous example. In the drawings, 3 'is a connecting member, and 6' is a pump jet, which are provided at the front part and the rear part of the hulls 2 'and 2', which are respectively double-hulled, via a diesel engine 7 '. It is.

上記構成の三胴船体は前例のものと比べ、より拡大された甲板を安定的に得られるものとなるのであり、このさい中央の比較的小容積の浮用空胴体2’は航行中の船体1’,1’間で生ずる波浪抵抗を可及的に小ならしめる整流作用効果を発揮させるものとなる。   Compared to the previous example, the three-hull hull with the above configuration can stably obtain an enlarged deck. At this time, the relatively small-capacity floating hull 2 'is the hull being navigated. The rectifying action effect that minimizes the wave resistance generated between 1 'and 1' as much as possible is exhibited.

本考案による両頭船は上記の如き構成であって、船底にはプロペラの如き突起物が全くないので船体抵抗の減少が図れる。而して、そのポンプジェットはその水の取入れ口を船体下方へ下向きに設けたものとなすのであり、この構成では船底より10cm〜15cmの如き低吃水船での使用が可能となり、また少ない水量で大きなスラストを発生し、360°旋回を含む全方位の操船が可能となるので高い操船機能の発揮されるものとなる。なお、上記構成は他のポンプジェットやプロペラとの比較で、騒音や振動なども少なくて快適性にも優れたものである。   The double-headed ship according to the present invention has the above-described configuration, and since there is no projection such as a propeller on the bottom of the ship, the hull resistance can be reduced. Thus, the pump jet has its water intake port facing downward in the hull. With this configuration, it can be used on low dredgers such as 10 to 15 cm from the bottom of the ship, and the amount of water is small. A large thrust is generated in this way, and it is possible to steer all directions including a 360 ° turn, so that a high maneuvering function is exhibited. In addition, the said structure has few noises, vibrations, etc. and is excellent also in comfort compared with other pump jets and propellers.
