【課題】スクリューの推進力を高めて高速化した省エネ船を提供する。【解決手段】スクリュー１前部の両舷に海水誘導板２の後端を蝶着し、該前端を油圧シリンダー３で自在に開閉できるように構成した。これにより、航行時、両舷の海水誘導板を油圧シリンダーで開ければ、今まで、両舷に沿って流れていた海水も、海水誘導板に誘導されてスクリュー部に流れ込み、スクリュー部の海水面が上昇してスクリューは、さながら、深海で海水に包まれた状態になって、海水密度が増すので、スクリューが海水を押す力が高まる。したがって、その反作用も高まるので、船速を早くすることができる。そのため、燃料を相当節約できるので経済的であり、省エネ船として活用することができる。【選択図】図１The present invention provides an energy-saving ship that increases the propulsive force of a screw to increase the speed. A rear end of a seawater guide plate 2 is hinged on both sides of a front portion of a screw 1 so that the front end can be freely opened and closed by a hydraulic cylinder 3. As a result, if the seawater guide plates on both sides are opened with hydraulic cylinders during navigation, the seawater that has been flowing along both sides until now will be guided to the seawater guide plate and flow into the screw part. As the screw rises, the screw is in a state of being surrounded by seawater in the deep sea, and the density of the seawater increases, so the force with which the screw pushes the seawater increases. Therefore, the reaction also increases, so that the boat speed can be increased. As a result, fuel can be saved considerably, which is economical and can be used as an energy-saving ship.

Description

本発明は、スクリューの推進力を高めて高速化した省エネ船に関する。  The present invention relates to an energy-saving ship that is increased in speed by increasing the propulsive force of a screw.

従来、スクリューが推進力を得る海水は、船首から船尾に流れる海水が主な対象であった。そのため、船速は燃料に見合う分しか出せなかった。  Conventionally, seawater from which a screw obtains a propulsive force has mainly been seawater flowing from the bow to the stern. As a result, the ship speed was only suitable for the fuel.

本発明は、両舷の海水も流入させてスクリューの推進力を高め、今以上に高速化することを目的とする。  An object of the present invention is to increase the propulsive force of the screw by causing the seawater of both sides to flow in, and further increase the speed.

そして、本発明は、上記目的を達成するため、スクリュー前部の両舷に海水誘導板を設置し、該後端をスクリューの付根部分の前部両舷に蝶着し、該海水誘導板の前端部分の船腹には、凹みを設けて油圧シリンダーを設置し、該本体を凹みに、ロッドは海水誘導板の前端部分に枢着し、油圧シリンダーを操作して海水誘導板を自在に開閉できるようにしたものである。
なお、使用する油圧シリンダーはロッド側トラニオン形が取り付けやすく、また、点検しやすい。また、油圧シリンダーの代りにエアシリンダーを設置してもよく、海水誘導板は他の方式で開閉するようにしてもよい。And in order to achieve the above-mentioned object, the present invention installs a seawater guide plate on both sides of the screw front part, and attaches the rear end to the front part of the root part of the screw, A hydraulic cylinder is installed in the hull of the front end with a recess, the body is recessed, and the rod is pivotally attached to the front end of the seawater guide plate, and the seawater guide plate can be opened and closed freely by operating the hydraulic cylinder. It is what I did.
In addition, the rod cylinder trunnion type is easy to install and easy to check. Further, an air cylinder may be installed instead of the hydraulic cylinder, and the seawater guide plate may be opened and closed by another method.

上記の課題解決手段による作用は次の通りである。すなわち、航行時、両舷の海水誘導板を、油圧シリンダーで開ければ、今まで、両舷に沿って流れていた海水も、海水誘導板に誘導されてスクリュー部に流れ込み、スクリュー部の海水面が上昇し、スクリューは、さながら、深海で海水に包まれた状態になって、海水密度が増すので、スクリューが海水を押す力が高まる。
したがって、その反作用も高まるので、船速を早くすることができる。The operation of the above problem solving means is as follows. In other words, when sailing, if the seawater guide plates on both sides are opened with hydraulic cylinders, the seawater that has been flowing along both sides until now will be guided to the seawater guide plate and flow into the screw part. And the screw is in a state of being surrounded by seawater in the deep sea, and the density of the seawater increases, so that the force with which the screw pushes the seawater increases.
Therefore, the reaction also increases, so that the boat speed can be increased.

上述したように、海水誘導板を設置したので、船速を早めることができる。
したがって、燃料を相当節約できるので経済的であり、省エネ船として活用することができる。
なお、本発明の構造簡単で、建造する船のみならず、就役中の船にも実施可能である等の諸効果を有するものである。Since the seawater guide plate is installed as described above, the boat speed can be increased.
Therefore, the fuel can be saved considerably, which is economical and can be used as an energy saving ship.
The structure of the present invention is simple, and has various effects such as being able to be implemented not only on ships to be built but also on ships in service.

以下、本発明の実施の形態を図１から図４について説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図１と図２の２はスクリュー１前部の両舷に配置した海水誘導板で、該後端をスクリュー１の付根部分の前部両舷に蝶着している。３は海水誘導板２の前端部分の船腹に設けた凹み４に設置した油圧シリンダーで、該本体を凹み４に、ロッドは海水誘導板の前端部分に枢着している。
図３と図４は、ロッド側トラニオン形油圧シリンダーの取り付け例で、凹み４を角形に形成して奥側を塞ぎ、該凹み４の前側の上下に丸孔を開け、該丸孔にシリンダー取り付け板５に取り付けたシリンダー保持筒６を挿入してトラニオン７を枢着し、シリンダー取り付け板５は凹み４の上下面にボルト８で取り付け、而して、ロッドに１山先端金具９をねじ込み、相対する海水誘導板２には１山先端金具９を夾む連結金具１０を取り付け、該連結金具１０と１山先端金具９をピン１１で枢着している。2 in FIG. 1 and FIG. 2 are seawater guide plates arranged on both sides of the front part of the screw 1, and the rear ends thereof are hinged to both front parts of the root portion of the screw 1. 3 is a hydraulic cylinder installed in a recess 4 provided on the hull of the front end portion of the seawater guide plate 2. The main body is in the recess 4 and the rod is pivotally attached to the front end portion of the seawater guide plate.
3 and 4 are examples of rod-side trunnion-type hydraulic cylinder mounting. The recess 4 is formed in a square shape to close the back side, and a round hole is formed on the top and bottom of the recess 4 and the cylinder is mounted in the round hole. The cylinder holding cylinder 6 attached to the plate 5 is inserted and the trunnion 7 is pivotally attached. The cylinder mounting plate 5 is attached to the upper and lower surfaces of the recess 4 with bolts 8, and the single end fitting 9 is screwed into the rod. A connecting metal fitting 10 sandwiching a single tip metal fitting 9 is attached to the opposing seawater guide plate 2, and the connecting metal fitting 10 and the single tip metal fitting 9 are pivotally attached by a pin 11.

以上において、海水誘導板は航行時に開き、荒天時は閉じる。また、入・出港時や港内は安全上閉じる。  In the above, the seawater guide plate opens during navigation and closes during stormy weather. In addition, the port is closed for safety when entering and leaving the port.
