Description

本発明は、動力式船舶の推進システムに関し、詳しくは推進効率を向上させることができ、船舶の喫水線が浅い時にも対応できる推進システムに関するものである。 The present invention relates to a propulsion system for a powered ship, and more specifically to a propulsion system capable of improving propulsion efficiency and responding even when the waterline of the ship is shallow.

船外機は内陸の河川、湖または近海を航行する小型船舶に適用し、船尾に着脱可能に装着される動力装置である。船外機は内燃機関またはモーターなどが生じた動力をスクリュープロペラに伝達し、スクリュープロペラを旋転させることによって船舶を前進させることが役割である。 An outboard motor is a power unit that is applied to small vessels navigating inland rivers, lakes, or inshore waters and is detachably attached to the stern. The outboard motor is responsible for transmitting the power generated by the internal combustion engine or the motor to the screw propeller and rotating the screw propeller to move the ship forward.

船外機の推進効率を良好に維持するために、スクリュープロペラ全体を水面下に沈めて十分に喫水させることは従来の設計である。しかしながら、このような設計は水の抵抗を増大させるだけでなく、スクリュープロペラが河床に衝突するか、ビニール袋、漁網または水草などの異物を巻き込んで損壊する、スクリュープロペラが水中生物に傷を付けるといった問題がよく発生する。 In order to maintain good propulsion efficiency of the outboard motor, it is a conventional design that the entire screw propeller is submerged under the water surface to allow sufficient draft. However, such a design not only increases water resistance, but also causes the screw propeller to collide with the riverbed or entrain and damage foreign objects such as plastic bags, fishing nets or aquatic plants, and the screw propeller damages aquatic organisms. Problems often occur.

本発明は、推進効率を向上させることができ、船舶の喫水線が浅い時にも対応できる動力式船舶の推進システムを提供することを主な目的とする。 An object of the present invention is to provide a propulsion system for a powered ship, which can improve propulsion efficiency and can handle even when the waterline of the ship is shallow.

上述した課題を解決するため、推進システムは支持部材、船外機、流体誘導部材および引水部を備える。支持部材は動力式船舶の船尾に装着される。船外機は支持部材に装着され、羽根車を有する。羽根車は軸心の位置が動力式船舶の船底より高い。流体誘導部材は環状流体誘導部および噴射ノズルを有する。環状流体誘導部は羽根車に被さって装着される。噴射ノズルは羽根車の近くに配置され、環状流体誘導部の後端部に連結される。引水部は支持部材の下方に位置するように動力式船舶の船尾に装着され、引水口、排水口および引水流路を有する。引水口は引水部の底部に形成される。排水口は環状流体誘導部に向かう。引水流路は引水口と排水口の間に形成される。 In order to solve the above-mentioned problems, the propulsion system includes a support member, an outboard motor, a fluid guide member, and a water drawing unit. The support member is mounted on the stern of a powered vessel. The outboard motor is mounted on a support member and has an impeller. The position of the axis of the impeller is higher than the bottom of the powered ship. The fluid guiding member has an annular fluid guiding portion and an injection nozzle. The annular fluid guide is mounted over the impeller. The injection nozzle is located near the impeller and is connected to the rear end of the annular fluid guide. The water intake is mounted on the stern of a powered vessel so as to be located below the support member and has a water intake, a drain and a water flow path. The water intake is formed at the bottom of the water intake. The drainage port faces the annular fluid guide. The water intake channel is formed between the water intake and the drain.

上述した構造特徴により、羽根車が回転開始すると、船底の水流は引水部の引水口から引水流路内に吸い込まれ、続いて引水部の排水口から環状流体誘導部内に送り込まれ、続いて羽根車によって整流され、噴射ノズルから噴出される。噴出された水流は低圧で流量が大きい状態である。つまり、従来の技術と比べて本発明は、推進効率を向上させることができるだけでなく、船舶の喫水線が浅い時にも対応できる。 Due to the structural features described above, when the impeller starts to rotate, the water flow at the bottom of the ship is sucked into the water flow path from the water intake of the water intake, then sent into the annular fluid guide from the drain of the water, and then the blades. It is rectified by the car and ejected from the injection nozzle. The ejected water flow is in a state of low pressure and large flow rate. That is, as compared with the conventional technique, the present invention can not only improve the propulsion efficiency but also cope with the shallow water line of the ship.

In the specification, directional terms are expressed based on the directions shown in the drawings. The same reference numerals in the drawings indicate structural features of the same or similar parts.

（一実施形態）
図１から図３に示すように、本発明の一実施形態による推進システム１６は支持部材１８、船外機２０、流体誘導部材３４および引水部４０を備える。 (One Embodiment)
As shown in FIGS. 1 to 3, the propulsion system 16 according to the embodiment of the present invention includes a support member 18, an outboard motor 20, a fluid guiding member 34, and a water drawing portion 40.

支持部材１８は、船尾１２の頂部の近くに配置され、溶接方式またはボルトなどの締付部材によって船尾１２に固定される。 The support member 18 is arranged near the top of the stern 12 and is fixed to the stern 12 by a welding method or a tightening member such as a bolt.

船外機２０は、ハウジング２２、拡張ボックス２４、支え部２６、ギアボックス２８、羽根車３０およびスワール防止板３２を有する。ハウジング２２は周知のエンジン（図中未表示）に被さる。拡張ボックス２４は周知の駆動軸（図中未表示）を格納するためにハウジング２２の下方に連結される。支え部２６は拡張ボックス２４の前側面に配置される。船外機２０は支え部２６によって支持部材１８に装着される。ギアボックス２８は駆動軸と連結するために拡張ボックス２４の下方に配置される。スワール防止板３２はギアボックス２８と拡張ボックス２４との間に配置される。図２に示すように、羽根車３０はギアボックス２８の後端部に連結され、軸心の位置が船底１４より高い。上述した構造特徴により、エンジンが生じた動力は駆動軸によってギアボックス２８に伝達され、続いてギアボックス２８によって減速し、そののち羽根車３０に伝達され、羽根車３０を旋転させることができる。 The outboard motor 20 has a housing 22, an expansion box 24, a support 26, a gearbox 28, an impeller 30, and a swirl prevention plate 32. The housing 22 covers a well-known engine (not shown in the figure). The expansion box 24 is connected below the housing 22 to house a well-known drive shaft (not shown). The support portion 26 is arranged on the front side surface of the expansion box 24. The outboard motor 20 is attached to the support member 18 by the support portion 26. The gearbox 28 is located below the expansion box 24 to connect with the drive shaft. The swirl prevention plate 32 is arranged between the gearbox 28 and the expansion box 24. As shown in FIG. 2, the impeller 30 is connected to the rear end of the gearbox 28, and the position of the axis is higher than the bottom 14 of the ship. Due to the structural features described above, the power generated by the engine can be transmitted to the gearbox 28 by the drive shaft, subsequently decelerated by the gearbox 28, and then transmitted to the impeller 30 to rotate the impeller 30.

流体誘導部材３４は、環状流体誘導部３６および噴射ノズル３８を有する。環状流体誘導部３６は船外機２０のスワール防止板３２に装着されて羽根車３０の全体およびギアボックス２８の一部分を遮蔽する。噴射ノズル３８は羽根車３０の近くに配置され、ボルトなどの締付部材によって環状流体誘導部３６の後端部に連結される。 The fluid guiding member 34 has an annular fluid guiding portion 36 and an injection nozzle 38. The annular fluid guide portion 36 is attached to the swirl prevention plate 32 of the outboard motor 20 to shield the entire impeller 30 and a part of the gearbox 28. The injection nozzle 38 is arranged near the impeller 30 and is connected to the rear end portion of the annular fluid guiding portion 36 by a tightening member such as a bolt.

引水部４０は、支持部材１８の下方に配置され、溶接方式またはボルトなどの締付部材によって船尾１２に固定され、引水口４２、排水口４４および引水流路４６を有する。引水口４２は引水部４０の底部に形成され、位置が船底１４と一致する。排水口４４は環状流体誘導部３６に向かって引水部４０の後端部に形成される。引水流路４６は引水口４２と排水口４４の間に斜めに伸びて形成される。 The water intake unit 40 is arranged below the support member 18, is fixed to the stern 12 by a welding method or a tightening member such as a bolt, and has a water intake port 42, a drainage port 44, and a water intake flow path 46. The water intake 42 is formed at the bottom of the water intake 40, and its position coincides with the bottom 14 of the ship. The drain port 44 is formed at the rear end of the water drawing portion 40 toward the annular fluid guiding portion 36. The water intake flow path 46 is formed so as to extend diagonally between the water intake port 42 and the drainage port 44.

上述した構造特徴により、羽根車３０が回転開始すると、船底１４の水流は引水部４０の引水口４２から引水流路４６内に吸い込まれ、続いて引水部４０の排水口４４から環状流体誘導部３６に送り込まれ、続いて羽根車３０によって整流され、噴射ノズル３８から噴出される。噴出された水流は低圧で流量が大きい状態である。船舶１０を減速または停止させる際、羽根車３０を減速、停止させ、続いて逆方向に回転させればよい。 Due to the structural features described above, when the impeller 30 starts rotating, the water flow of the bottom 14 is sucked into the water flow path 46 from the water intake 42 of the water intake 40, and subsequently from the drain 44 of the water intake 40 to the annular fluid guide portion. It is fed to 36, subsequently rectified by the impeller 30, and ejected from the injection nozzle 38. The ejected water flow is in a state of low pressure and large flow rate. When decelerating or stopping the ship 10, the impeller 30 may be decelerated and stopped, and then rotated in the opposite direction.

本発明による推進システム１６は先行技術に優れた点が下記のとおりである。 The propulsion system 16 according to the present invention has the following advantages in the prior art.

１）推進システム１６は船外機２０の配置位置が支持部材１８によって高くなり、羽根車３０が環状流体誘導部３６内に旋転するため、河床に衝突するか異物を巻き込むことが原因で損壊すること、船底１４に接近する魚類またはダイバーを負傷させてしまうことが起こりにくい。従って、本発明は船舶１０の喫水線が浅い時に対応できるだけでなく、救難船舶に適用できる。 1) The position of the outboard motor 20 is raised by the support member 18, and the impeller 30 rotates in the annular fluid guide portion 36, so that the propulsion system 16 is damaged due to collision with the riverbed or entrainment of foreign matter. In addition, it is unlikely that fish or divers approaching the bottom 14 will be injured. Therefore, the present invention can be applied not only to a shallow water line of a ship 10 but also to a rescue ship.

２）推進システム１６が稼働する際、水流は引水部４０内に吸い込まれ、続いて引水部４０から環状流体誘導部３６内に送り込まれ、羽根車３０によって整流され、続いて噴射ノズル３８から噴出されるため、船尾１２の後方にスワールが発生しにくい。従って、本発明は推進効率および船舶１０の制御性能を向上させることができる。 2) When the propulsion system 16 operates, the water flow is sucked into the water drawing unit 40, then sent from the water drawing unit 40 into the annular fluid guiding unit 36, rectified by the impeller 30, and then ejected from the injection nozzle 38. Therefore, a swirl is unlikely to occur behind the stern 12. Therefore, the present invention can improve the propulsion efficiency and the control performance of the ship 10.
