動力式船艇之推進系統Propulsion system of power boat

本發明與動力式船艇之推進系統有關，特別是指一種可以增加推進效率且在船艇吃水較淺時亦可適用之推進系統。The present invention is related to the propulsion system of a powered boat, in particular to a propulsion system that can increase the propulsion efficiency and is also applicable when the boat has a shallow draft.

船外機為一種安裝於船尾的可拆式動力裝置，主要是將動力源(如內燃機或電機)所提供的動力傳遞至螺旋槳，藉由螺旋槳的旋轉來推動船艇前進，一般適用於在內陸河川、湖泊或近海航行的小型船艇。The outboard motor is a detachable power device installed at the stern. It mainly transmits the power provided by the power source (such as internal combustion engine or electric motor) to the propeller. The propeller rotates to push the boat forward. It is generally suitable for use in Small boats sailing on land, rivers, lakes or offshore.

為了讓船外機具有良好的推進效率，在傳統設計上會讓螺旋槳整個沉入水中，以確保螺旋槳具有足夠的吃水深度，但是這樣的方式除了導致水阻的增加之外，同時容易讓螺旋槳碰撞到河床或者攪入異物(如塑膠袋、漁網或水草等)，進而造成螺旋槳的損壞，甚至也可能因此傷害到水中生物。In order to make the outboard aircraft have good propulsion efficiency, in the traditional design, the propeller is submerged in the water to ensure that the propeller has sufficient draft. However, this method not only causes an increase in water resistance, but also easily collides with the propeller. Go to the riverbed or stir in foreign objects (such as plastic bags, fishing nets or water plants, etc.), which will cause damage to the propeller, and may even harm aquatic life.

本發明之主要目的在於提供一種動力式船艇之推進系統，其能提高推進效率，並且在船艇的吃水深度較淺時亦能適用。The main purpose of the present invention is to provide a propulsion system for a powered boat, which can improve the propulsion efficiency and is also applicable when the draft of the boat is shallow.

為了達成上述主要目的，本發明之推進系統包含有一個支撐架、一個船外機、一個導流組件，以及一個引水座。該支撐架設於該動力式船艇的船尾；該船外機設於該支撐架且具有一個葉輪，該葉輪之軸心位置高於該動力式船艇的船底；該導流組件具有一個導流環及一個噴嘴，該導流環罩設於該葉輪，該噴嘴連接於該導流環之後端且鄰設於該葉輪；該引水座設於該動力式船艇的船尾且位於該支撐架的下方，該引水座之底部具有一個引水口，且該引水座具有一個朝向該導流環之排水口，該引水口與該排水口之間形成一條引水道。In order to achieve the above-mentioned main purpose, the propulsion system of the present invention includes a support frame, an outboard motor, a deflector assembly, and a water diversion seat. The support is installed on the stern of the power boat; the outboard motor is installed on the support frame and has an impeller, the shaft of the impeller is higher than the bottom of the power boat; the guide assembly has a guide Ring and a nozzle, the guide ring is arranged on the impeller, the nozzle is connected to the rear end of the guide ring and adjacent to the impeller; the pilot seat is arranged at the stern of the powered boat and located at the support frame Below, the bottom of the water diversion seat has a water intake, and the water diversion seat has a drainage port facing the diversion ring, and a water diversion channel is formed between the water intake and the drainage port.

藉由上述設計，當該葉輪開始轉動時，該船底的水流會由該引水座之引水口被吸入該引水道內，然後由該引水座之排水口排送至該導流環內，最後經過該葉輪的整流作用之後從該噴嘴噴出，使水流呈現低壓且大流量的噴射狀態，如此相較於先前技術可以提高推進效率，並且在該動力式船艇的吃水深度較淺時亦可適用。With the above design, when the impeller starts to rotate, the water flow at the bottom of the ship will be sucked into the diversion channel from the water intake of the water diversion seat, and then discharged into the diversion ring from the drainage port of the water diversion seat, and finally pass through After the rectification action of the impeller, it is sprayed from the nozzle to make the water flow present a low-pressure and large-flow spray state. Compared with the prior art, the propulsion efficiency can be improved, and it is also applicable when the draught of the power boat is shallow.

Secondly, in the following embodiments and drawings, the same element numbers represent the same or similar elements or structural features.

請參閱圖1至圖3，本發明之推進系統16包含有一個支撐架18、一個船外機20、一個導流組件34，以及一個引水座40。Please refer to FIGS. 1 to 3, thepropulsion system 16 of the present invention includes asupport frame 18, anoutboard motor 20, adiversion assembly 34, and awater diversion seat 40.

支撐架18利用焊接或是螺絲鎖設的方式固定於船尾12且鄰近於船尾12的頂端。Thesupport frame 18 is fixed to thestern 12 and adjacent to the top of thestern 12 by welding or screw locking.

船外機20具有一個用來遮蓋引擎(此為習用技術，圖中未示)之殼體22，殼體22的下方接設一個用來容納驅動軸(此為習用技術，圖中未示)之延伸箱24，延伸箱24的前側面設置一個托架26，船外機20利用托架26掛設於支撐架18，延伸箱24的下方接設一個用來連接驅動軸之齒輪箱28，齒輪箱28與延伸箱26之間設有一個防渦擋板32，齒輪箱28之後端則是跟一個葉輪30作連接，如圖2所示，葉輪30的軸心位置高於船底14。藉此，引擎所產生的動力經由驅動軸傳輸至齒輪箱28，經過齒輪箱28的減速之後再傳送至葉輪30，使葉輪30產生旋轉。Theoutboard motor 20 has acasing 22 for covering the engine (this is a conventional technology, not shown in the figure), and a drive shaft is connected below the casing 22 (this is a conventional technology, not shown in the figure) Theextension box 24 is provided with abracket 26 on the front side of theextension box 24. Theoutboard motor 20 is hung on thesupport frame 18 by using thebracket 26. Agear box 28 for connecting the drive shaft is connected below theextension box 24. Ananti-vortex baffle 32 is provided between thegear box 28 and theextension box 26, and the rear end of thegear box 28 is connected with animpeller 30. As shown in FIG. 2, the shaft center of theimpeller 30 is higher than thebottom 14 of the ship. In this way, the power generated by the engine is transmitted to thegear box 28 via the drive shaft, and is decelerated by thegear box 28 and then transmitted to theimpeller 30 to cause theimpeller 30 to rotate.

導流組件34具有一個導流環36與一個噴嘴38。導流環36設於船外機20之防渦擋板32且將整個葉輪30及齒輪箱28的一部分給罩設住，噴嘴38利用螺絲鎖固的方式接設於導流環36之後端且鄰設於葉輪30。Theflow guide assembly 34 has aflow guide ring 36 and anozzle 38. Thedeflector ring 36 is arranged on theanti-vortex baffle 32 of theoutboard motor 20 and covers a part of theentire impeller 30 and thegear box 28. Thenozzle 38 is connected to the rear end of thedeflector ring 36 by screw locking. Adjacent to theimpeller 30.

引水座40利用焊接或是螺絲鎖設的方式固定於船尾12且位於支撐架18的下方。引水座40之底部具有一個引水口42，引水口42的位置實質上跟船底14齊平，引水座40之後端具有一個朝向導流環36之排水口44，引水口42與排水口44之間形成一條呈斜向延伸之引水道46。Thewater guide base 40 is fixed to thestern 12 by welding or screw locking and is located below thesupport frame 18. The bottom of thewater diversion seat 40 has awater intake 42 which is substantially flush with thebottom 14 of the ship. The rear end of thewater diversion seat 40 has adrainage port 44 facing thediversion ring 36 between thewater intake 42 and the drainage port 44 Awater channel 46 extending diagonally is formed.

由上述結構可知，當葉輪30開始轉動時，船底14的水流會由引水座40之引水口42被吸入引水道46內，然後由引水座40之排水口44排送至導流環36內，接著經過葉輪30的整流之後從噴嘴38噴出，使水流呈現低壓且大流量的噴射狀態。若想要船艇10減速或停止時，則是控制葉輪30由減速、停止至逆向旋轉。It can be seen from the above structure that when theimpeller 30 starts to rotate, the water flow of theship bottom 14 will be sucked into thediversion channel 46 from thewater intake 42 of thewater diversion seat 40, and then discharged into thediversion ring 36 from thedrainage port 44 of thewater diversion seat 40. After being rectified by theimpeller 30, it is sprayed from thenozzle 38, so that the water flow presents a low-pressure and large-flow spray state. When it is desired to decelerate or stop theboat 10, theimpeller 30 is controlled to decelerate and stop to reverse rotation.

綜上所陳，本發明之推進系統16與先前技術相較之下具有以下優點：In summary, compared with the prior art, thepropulsion system 16 of the present invention has the following advantages:

1) 利用支撐架18提高船外機20的安裝高度，再加上葉輪30在導流環36的內部旋轉，較不易碰撞到河床或是被異物所勾纏而導致損壞，而且也比較不會傷害到船底14附近的魚類、泳客或潛水人員，因而在船艇10的吃水深度較淺時亦可適用，另外也相當適合應用在救難船艇。1) Use thesupport frame 18 to increase the installation height of theoutboard motor 20, and theimpeller 30 rotates inside thedeflector ring 36, it is less likely to hit the riverbed or be entangled by foreign objects and cause damage, and it is also less likely to be damaged Injury to fishes, swimmers or divers near thebottom 14 of the ship, so it can also be applied when the draft of theship 10 is relatively shallow, and it is also quite suitable for use in rescue ships.

2) 在運作時，水流先被吸入引水座40內，然後從引水座40被導引至導流環36內，最後經過葉輪30的整流之後再從噴嘴38往後噴出，因此在船尾12的後方不易產生渦流，因而提高推進效率及增加船艇10的操控性。2) During operation, the water flow is first sucked into thewater diversion seat 40, and then guided from thewater diversion seat 40 to thediversion ring 36, and finally rectified by theimpeller 30, and then sprayed out from thenozzle 38 back, so the water flow is in thestern 12 The rear is not easy to generate eddy currents, thus improving the propulsion efficiency and increasing the maneuverability of theboat 10.
