Description

本発明は、エンジン又は電動の駆動源により作動するキャタピラで海上を高速航行するキャタピラ推進式高速船に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caterpillar propulsion type high-speed ship that sails at high speed on the sea with caterpillars that are driven by an engine or an electric drive source.

特許文献１には、従来の船の推進部であるスクリューの代わりに船の左右両側に櫂を付けたキャタピラにより、船を航行させる水上キャタピラ船が開示されている。 Patent Literature 1 discloses a water caterpillar ship in which the ship is navigated by caterpillars having paddles attached to both left and right sides of the ship instead of propelling propellers of conventional ships.

特許文献２には、内側が平行直線の双胴船の間にある水を、後方に送り出す複数の水かきを、水平移動させて推進力とする構造の高速船で、大型の場合は、双胴の中心先端に突出し・伸縮可能な低造波抵抗装置を設け、高速のため受ける風力を揚力、浮力、及びジェットに使用し、更に船体の下部には制御できる翼をもった没水体をもつ船が開示されている。 Patent Document 2 describes a high-speed boat with a structure in which a plurality of paddles that send water backward between catamarans whose inner sides are parallel straight lines are moved horizontally and used as propulsion force. A ship with a protruding and expandable low wave resistance device at the tip of the center of the hull, using the wind force received due to high speed for lift, buoyancy and jet, and a submerged body with wings that can be controlled at the bottom of the hull is disclosed.

特許文献１の発明は、左右の全長にわたり右舷や左舷にキャタピラを取り付けているので、船への乗り降りが不便で危険であるという問題があった。また、右舷や左舷に取り付けたキャタピラが波の影響を直接に受けることから、キャタピラの水掻きが回転する方向と異なる方向からの波の力等により水掻きを含むキャタピラが破損する危険があるという問題もあった。 The invention of Patent Document 1 has a problem that it is inconvenient and dangerous to get on and off a ship because caterpillars are attached to the starboard side and the port side over the entire length of the left and right sides. In addition, since the caterpillars attached to the starboard and port sides are directly affected by the waves, there is a risk that the caterpillar including the paddles will be damaged by the force of the waves from a direction different from the direction in which the paddles of the caterpillar rotate. there were.

特許文献２の発明は、後尾翼が船尾に突設され造波抵抗減少装置が船首に突設されていることから、前記後尾翼と前記造波抵抗減少装置とを同時に機能発揮させるために両者を海中に浸漬させるには、船首と船尾との喫水差のコントロールとしてイーブントリムを意図していることが明らかであるので、高速航行が困難な船舶であるという問題があった。 In the invention of Patent Document 2, since the tail wing protrudes from the stern and the wave-making resistance reduction device protrudes from the bow, both the tail wing and the wave-making resistance reduction device are provided in order to exhibit their functions at the same time. Since it is clear that even trim was intended to control the draft difference between the bow and the stern, there was a problem that the ship was difficult to navigate at high speed.

本発明はこうした問題に鑑み創案されたもので、安全に乗り降りができ、キャタピラが波の影響を受けにくくして破損しにくく、高速航行が可能なキャタピラ推進式高速船を提供することを課題とする。 SUMMARY OF THE INVENTION The object of the present invention is to provide a caterpillar propulsion type high-speed boat that allows safe boarding and alighting, that is less likely to be damaged by the influence of waves, and that is capable of high-speed sailing. do.

請求項１に記載のキャタピラ推進式高速船は、平面視で単胴船の右舷と左舷との間でかつ後端部に設けた、甲板から船底まで貫通した単数又は複数の切欠き部であるキャタピラトンネルに、又は、三胴船の主船体と左右の副船体それぞれとの間の後部に、エンジン又はモータの駆動源の駆動力が伝達されて回転する、所定の間隔で所定の数の水かきを突設したキャタピラを備え、前記キャタピラが、長手方向を前記単胴船又は前記三胴船の船首と船尾を結ぶ方向に平行になるように、かつ、前記キャタピラの環状体の下側が前記単胴船又は前記三胴船の船体中央部の船底と略同じ高さになるように配設され、水平断面形状が丸い前端部と尖った後端部との間を流線形状とした左右対称の形状を有し、所定の前後方向の長さと所定の上下方向の長さを有して垂設されたラダーと、前記ラダーの上下方向の略中間部から前記ラダーの前端から後端にかけて前記ラダーに対して左右方向に対称的に突設させた、所定の左右方向の長さと所定の上下方向の厚みの翼形状を有する衝撃吸収滑走翼と、前記ラダーの前端部と前記衝撃吸収滑走翼の前端部を固定した、垂直方向の回転軸であるラダーシャフトと、を有する衝撃吸収型滑走式ラダーを備え、前記衝撃吸収型滑走式ラダーを、前記衝撃吸収滑走翼が高速航行時の喫水の高さとなる高さに、前記単胴船の場合は右舷と左舷の２か所、又は、前記三胴船の場合は主船体の右舷と左舷の２か所に配設したことを特徴とする。 The caterpillar propulsion type high-speed boat according to claim 1 is a single or a plurality of cutouts penetrating from the deck to the bottom of the monohull, provided between the starboard side and the port side of the monohull ship in plan view and at the rear end. A predetermined number of flippers are rotated at predetermined intervals by the driving force of an engine or motor driving source being transmitted to the caterpillar tunnel or to the rear portion between the main hull and the left and right sub-hulls of the trimaran. so that the longitudinal direction of the caterpillar is parallel to the direction connecting the bow and the stern of the monohull or the trimaran, and the lower side of the annular body of the caterpillar is the monohull The hull or trimaran is arranged so as to be at approximately the same height as the bottom of the hull in the center of the hull, and has a horizontal cross-sectional shape that is bilaterally symmetrical with a streamlined shape between a rounded front end and a sharp rear end. and has a predetermined length in the front-rear direction and a predetermined length in the vertical direction, and a ladder that is vertically provided; A shock-absorbing gliding wing having a wing shape with a predetermined length in the lateral direction and a predetermined thickness in the vertical direction, which is projected symmetrically in the left-right direction with respect to the rudder; and a rudder shaft, which is a vertical axis of rotation, to which the front end of the impact-absorbing planing rudder is fixed. In the case of the monohull, it is arranged on the starboard side and the port side of the main hull, or in the case of the trimaran, it is arranged on the starboard side and the port side of the main hull. .

本発明のキャタピラ推進式高速船は、キャタピラを船体の内部側に設け、波を船体でキャタピラの直接には当たらないように設けたので波の影響を受けにくく、船体中央部の船底と同じ深さのところで、すなわち高速航行時の喫水の喫水線近傍の深さで、水かきで水を掻くようにしたのでしっかりと船を前進させることができ、駆動源の回転数を上げることにより高速で航行させることができる。 In the caterpillar propulsion type high-speed boat of the present invention, the caterpillar is provided on the inner side of the hull so that waves do not hit the caterpillar directly with the hull. At high speed, that is, at a depth near the waterline of the draft during high-speed sailing, the water is paddled with a paddle, so the ship can be moved forward firmly, and by increasing the rotation speed of the drive source, it can be sailed at high speed. be able to.

また、キャタピラを右舷又は左舷には設けていないので、安全に乗り降りができ、横波の影響を受けにくいのでキャタピラが破損しにくいという効果を奏する。 In addition, since no caterpillar is provided on the starboard side or the port side, it is possible to get on and off safely, and since it is less affected by transverse waves, the caterpillar is less likely to be damaged.

また、水平翼である衝撃吸収滑走翼と垂直翼であるラダーを取り付けた、垂直方向のラダーシャフトで回転する衝撃吸収型滑走式ラダーを設けたので、高速航行時に船首が船尾より高くなるスターントリム状態において、波がきたら前記衝撃吸収滑走翼がクッションになって波の衝撃を緩和し、安定した高速航行ができ、前記ラダーで左右のかじ取りをすることができるという効果を奏する。 In addition, a shock-absorbing planing rudder that rotates with a vertical rudder shaft, which has horizontal shock-absorbing planing wings and a vertical rudder, is installed, so the bow is higher than the stern at high speeds. In this state, when a wave comes, the impact-absorbing gliding wing acts as a cushion to alleviate the impact of the wave, enabling stable high-speed sailing and steering left and right with the rudder.
