Abstract

<P>PROBLEM TO BE SOLVED: To provide a device capable of saving energy and increasing speed and also capable of reducing cost such as reducing the use of antifouling paint by reducing the resistance on a ship bottom by using air as if it is a roller. <P>SOLUTION: Several to tens of screen-like plates (fins) are installed on the outer part of a ship bottom to a hull shape, and air is poured therebetween to form layers of air bubbles between the ship bottom and sea water, etc., and the resistance received by the ship bottom is reduced thereby. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、船舶の船底が受ける海水等の抵抗に係り、空気により船底と海水等の間に膜を作り、海水等の抵抗を減少させる船体に関するものである。     The present invention relates to the resistance of seawater received by a ship bottom, and relates to a hull that reduces the resistance of seawater by forming a film between the ship bottom and seawater by air.

船舶が航行する際に船底が受ける抵抗に対しては、防汚塗料を塗り貝殻等が付着するのを減少させていた。
特開平１−２９３２９３号公報 特開平２−７７３９２号公報 Antifouling paint was applied to reduce the resistance of the bottom of the ship when navigating, reducing the adhesion of shells and the like.
JP-A-1-293293 JP-A-2-77392

解決しようとする問題点は、従来の技術では船底が受ける海水の抵抗をほとんど減少できなかった点である。     The problem to be solved is that the conventional technology could hardly reduce the resistance of seawater received by the ship bottom.

本発明は、船舶が航行する際に船底が受ける抵抗を、空気を船底と海水等の間に注入することにより、その抵抗をほとんどなくすることをもっとも主要な特徴とする。     The main feature of the present invention is that the resistance received by the ship bottom when the ship is sailing is almost eliminated by injecting air between the ship bottom and seawater.

以上説明したように空気をまさにコロのように使用して船底にかかる抵抗を減少することにより省エネルギーおよび高速化が図れることはもとより防汚塗料の使用が減少する等コスト軽減にも適用できる。     As described above, air can be used like a roller to reduce resistance applied to the bottom of the ship, thereby saving energy and increasing the speed, as well as reducing the use of antifouling paints.

船底外部に船首から船尾にかけて、船底から垂直に鉄等の金属もしくはプラスチック等で衝立状の板(フイン)を、船体の大きさにより、高さ十数cmから数十ｃｍの物を船体中心線より船腹方向に数ｃｍから数ｍの間隔で設置し、衝立状の板と板の間に船首船底に開けた開口部からパイプで送られた空気を送出する。空気は、甲板上の空気取り入れ口から吸気パイプで取り入れ機動通風機を介して送気パイプで船首船底外部に送出する。     From the bow to the stern outside the ship's bottom, vertically from the ship's bottom, a metal plate such as iron or plastic, or a plate (fin) with a height of several tens to several tens of centimeters depending on the size of the hull It is installed at intervals of several centimeters to several meters in the hull direction, and air sent by a pipe is sent out from an opening opened in the bow of the bow between the screen-like plates. Air is sent from the air intake on the deck to the outside of the bow bottom by an air supply pipe via an intake pipe and an intake ventilation.

図２は、本発明装置の縦断正面図であり、衝立状の板と板の間から空気が開口部から送出されるものである。 FIG. 1 is a longitudinal side view of the apparatus of the present invention, in which air is introduced from an intake port and is sent out from the bow bottom by a moving air blower.
FIG. 2 is a longitudinal front view of the device of the present invention, in which air is sent out from the openings between the screen-like plates.
