Description

船舶的推進導流裝置Ship's propulsion and flow guiding device

本新型是有關於一種船舶的部件，特別是指一種船舶的推進導流裝置。The present invention relates to a component of a ship, and more particularly to a propulsion and flow guiding device for a ship.

參閱圖1，現有的船舶1包括一船殼11，及一設置於該船殼11上，且位於行駛時之水線10下方的螺槳12。該船舶1是利用該螺槳12的轉動，於水中產生向前或向後的推進力以驅動該船舶1。由於該螺槳12的結構與作動方式的關係，當該螺槳12產生推力的同時，也會產生極大的紊流，所述的紊流會帶動周圍流體旋轉運動而損耗向前或向後的動能(稱為旋向動能損失)，因而對預期可產生的推進力產生不良影響。此時，若只是單純以增加該螺槳12轉速的方式來提高推進力，反而將會導致更大的紊流，同時也產生更多的旋向動能損失。Referring to Figure 1, the prior art vessel 1 includes a hull 11 and a propeller 12 disposed on the hull 11 and located below the waterline 10 during travel. The ship 1 utilizes the rotation of the propeller 12 to generate a forward or backward propulsive force in the water to drive the vessel 1. Due to the structure of the propeller 12 and the manner of actuation, when the propeller 12 generates thrust, it also generates a great turbulence, which will drive the surrounding fluid to rotate and lose forward or backward kinetic energy. (referred to as the kinetic energy loss), thus adversely affecting the propulsive force that can be expected. At this time, if the propulsion force is simply increased by increasing the rotation speed of the propeller 12, it will cause more turbulence and more kinetic energy loss.

為了減少因該螺槳12旋轉而產生的紊流，減少所述紊流對於該船舶1之推進所產生的不良影響，如圖2與圖3所示為一現有的導流裝置13，該導流裝置13設置於該螺槳12的相對前方，並包含一與該螺槳12同軸的本體130，及多片自該本體130呈放射狀向外延伸的導流片131。透過該等導流片131，能重新分佈該螺槳12前方流場。In order to reduce the turbulence caused by the rotation of the propeller 12, the adverse effect of the turbulence on the propulsion of the vessel 1 is reduced. As shown in FIG. 2 and FIG. 3, a conventional flow guiding device 13 is provided. The flow device 13 is disposed at the opposite side of the propeller 12 and includes a body 130 coaxial with the propeller 12 and a plurality of baffles 131 extending radially outward from the body 130. Through the baffles 131, the flow field in front of the propeller 12 can be redistributed.

然而，該船舶1的體積龐大，該螺槳12以及該等導流片131的體積自然十分巨大，該等導流片131的長度也較長，且相對於該本體130形成相當長的力臂。當該等導流片131在實際海域中運動時，會承受該螺槳12運轉產生的應力，難免會因該等導流片131長度的關係，相對於該本體130產生甚大的力矩，而所述力矩可能使得該等導流片131與該本體130相連處發生應力集中，進而產生結構損傷，影響船舶航行安全，故仍有待進一步的改善。However, the vessel 1 is bulky, the volume of the propeller 12 and the baffles 131 is naturally very large, the length of the baffles 131 is also long, and a relatively long force arm is formed with respect to the body 130. . When the baffles 131 move in the actual sea area, they will withstand the stress generated by the operation of the propeller 12, and inevitably generate a large torque relative to the body 130 due to the length of the baffles 131. The moment may cause stress concentration at the joint of the baffles 131 and the body 130, thereby causing structural damage and affecting the safety of the ship, so further improvement is needed.

因此，本新型之目的，即在提供一種能提高導流片之間的連接強度、降低導流片振動幅度，並能進一步使螺槳前方流場更均勻之船舶的推進導流裝置。Therefore, the object of the present invention is to provide a propulsion and guiding device for a ship which can improve the connection strength between the baffles, reduce the vibration amplitude of the baffle, and further make the flow field in front of the propeller more uniform.

於是，本新型船舶的推進導流裝置，包含一本體、至少三片彼此間隔而自該本體向外延伸的導流板、一連接該至少三片導流板中之至少二片導流板的第一補強板，及至少一連接於該至少三片導流板中之任二片相鄰導流板的第二補強板。Therefore, the propulsion and guiding device of the novel vessel comprises a body, at least three deflector plates spaced apart from each other and extending from the body, and at least two of the at least three deflectors a first reinforcing plate, and at least one second reinforcing plate connected to any two adjacent baffles of the at least three baffles.

定義一通過該本體的主軸、一自該主軸上下延伸而成的輔助面，及分別位於該輔助面左右兩側的一第一側及一第二側。該至少三片導流板是以垂直該主軸的方向向外延伸，且該至少三片導流板中的其中一片導流板位於該第一側，該至少三片導流板中的其餘導流板位於該第二側。A first surface and a second side are defined by a main shaft of the main body, an auxiliary surface extending from the main shaft, and a left side of the auxiliary surface. The at least three deflectors extend outward in a direction perpendicular to the main shaft, and one of the at least three deflectors is located on the first side, and the remaining guides of the at least three deflectors The flow plate is located on the second side.

每一片導流板具有一遠離該本體的端緣，及二彼此間隔且銜接於該端緣與該本體之間的側面。該第一補強板是連接該至少三片導流板中的至少二片導流板的端緣，且繞一平行該主軸之第一軸線而呈弧形延伸。該至少一第二補強板連接於該至少三片導流板中的任二片相鄰導流板的側面，且其位置介於與其連接的該導流板的該端緣與該本體間，該至少一第二補強板繞一平行該主軸之第二軸線而呈弧形延伸。Each of the baffles has an end edge away from the body, and two sides spaced apart from each other and engaging between the end edge and the body. The first reinforcing plate is connected to an end edge of at least two of the at least three deflectors, and extends in an arc around a first axis parallel to the main shaft. The at least one second reinforcing plate is connected to a side of any two adjacent ones of the at least three deflectors, and is located between the end edge of the deflector connected thereto and the body. The at least one second reinforcing plate extends in an arc about a second axis parallel to the main axis.

本新型之功效在於：透過該第一補強板及該至少一第二補強板來銜接該等導流板，能強化整體結構強度，避免該至少三導流板導引水流時產生振動，確實能提高該等導流板之間的連接強度，並透過該第一補強板及該至少一第二補強板來均勻該螺槳的前方流場，從而提升船舶推進效率。The effect of the present invention is that the first reinforcing plate and the at least one second reinforcing plate are connected to the baffles to strengthen the overall structural strength, and to avoid vibration when the at least three baffles guide the water flow, and indeed The connection strength between the baffles is increased, and the front flow field of the propeller is uniformed through the first reinforcing plate and the at least one second reinforcing plate, thereby improving the propulsion efficiency of the ship.

The first reinforcing plate 4 is connected to the end edge 31 of the two baffles 3 on the second side 222 and extends in an arc shape about a first axis L1 parallel to the main shaft 21. The second reinforcing plate 5 is connected between the deflector 3 on the first side 221 and the side 32 of one of the two baffles 3 on the second side 222, and its position is different from The end edge 31 of the connected baffle 3 and the body 2 are particularly preferably between 50% and 80% of the length of the baffle 3 away from the body 2 as shown in FIG. The distance between the second reinforcing plate 5 and the first reinforcing plate 4 relative to the main body 2 is different from that of the first reinforcing plate 4, thereby enhancing the reinforcing effect of the first reinforcing plate 4 and enhancing the overall reinforcement and support of the present invention. performance. Specifically, the first reinforcing plate 4 is for reinforcing the outer edge of the stable baffle 3, and the second reinforcing plate 5 is for reinforcing the block adjacent to the middle of the stable baffle 3.

繼續參閱圖4與圖5，該第二補強板5繞一平行該主軸21之第二軸線L2而呈弧形延伸，該第二軸線L2與該第一軸線L1皆與該主軸21重疊，也就是說，該第一補強板4與該第二補強板5實質上是呈同心圓弧狀。透過該第一補強板4與該第二補強板5，能在相鄰的導流板3之端緣31以及側面32之間形成連接，藉此固定相鄰之導流板3間的相對位置。尤其，藉由位於該第二側222之其中一片導流板3同時連接該第一補強板4及該第二補強板5的設計，使得每一片相鄰的導流板3都至少與該第一補強板4或該第二補強板5連接，進而使該等導流板3相對於該本體2而言被連接為一個整體，減少任一導流板3相對於該本體2產生過大力矩的可能性，確保該等導流板3能發揮預期之消除紊流的效果，也防止該等導流板3因長期承受力矩而受損。4 and FIG. 5, the second reinforcing plate 5 extends in an arc about a second axis L2 parallel to the main shaft 21, and the second axis L2 and the first axis L1 overlap with the main axis 21, That is, the first reinforcing plate 4 and the second reinforcing plate 5 are substantially concentric arc-shaped.

The lengths are different, such that when the first reinforcing plate 4 is connected to the end edge 31 of the baffles 3 on the second side 222, the first axis L1 will be spaced from the main axis 21 and the second axis L2 . That is, the center of the arc formed by the first reinforcing plate 4 and the second reinforcing plate 5 is eccentric to each other. Through the design that the first reinforcing plate 4 and the second reinforcing plate 5 are eccentric to each other, the different rotation patterns of the propeller 9 can be matched, and the deflecting mechanisms 3 of different lengths can be used to generate a specific guiding mechanism. At the same time, it is achieved that the baffles 3 are connected to each other and reinforced to form an integral body, thereby reducing the moment that the baffles 3 are subjected to with respect to the body 2.
