用於發電的線性往復式流體動力轉換系統Linear reciprocating fluid power conversion system for power generation

本發明是有關於一種流體動力轉換系統,特別是指一種用於發電的線性往復式流體動力轉換系統。The present invention relates to a fluid power conversion system, and more particularly to a linear reciprocating fluid power conversion system for power generation.

溫室效應、地球暖化的問題,導致各種天災日益嚴重,如何節能減碳,已成為全世界當前所需面對的重要課題。而風力發電、洋流發電、或波浪發電等自然能源的開發,即為適合台灣與全球許多國家發展的綠色能源科技。The problems of greenhouse effect and global warming have led to various natural disasters. How to save energy and reduce carbon has become an important issue facing the world. The development of natural energy such as wind power, ocean current power generation, or wave power generation is a green energy technology suitable for development in Taiwan and many countries around the world.

以風力發電為例,目前所使用的各種風機,主要分為水平軸式與垂直軸式風機,兩種型式的風機都以旋轉運動,驅動發電機發電。水平軸式的風機葉片,在不同半徑處,其旋轉切線速度不同,葉片旋轉所受的阻力亦不同,半徑愈大,切線速度愈大,葉片旋轉所受阻力愈大。故一般的設計,會沿著半徑增加的方向,逐漸縮減葉片的弦長,以適度縮減面積,降低阻力。然此舉亦降低了風機產生推力的有效面積。又不同半徑處的旋轉切線速度不同,若流體入流速度的方向一定,則在不同半徑處的切線速度與入流速度合成的合成流速不同,而使風機翼面所承受的攻角不同,不易於不同半徑處以最佳的攻角產生推力。垂直軸式的風機,雖無上述問題,但風機葉片與風向間形成的攻角,隨著旋轉運動而改變,亦無法保持於最佳攻角以提昇風機的輸出功率。Taking wind power as an example, the various types of fans currently used are mainly divided into horizontal axis and vertical axis fans. Both types of fans use rotational motion to drive generators to generate electricity. Horizontal-axis fan blades have different rotational tangential speeds at different radii, and the resistance to rotation of the blades is also different. The larger the radius, the larger the tangential speed, and the greater the resistance to rotation of the blades. Therefore, the general design will gradually reduce the chord length of the blade along the direction in which the radius increases, so as to moderately reduce the area and reduce the resistance. However, this also reduces the effective area of the thrust generated by the fan. The rotational tangential speeds at different radii are different. If the direction of the fluid inflow velocity is constant, the tangential velocity at different radii is different from the combined velocity of the inflow velocity, and the angle of attack of the fan airfoil is different, which is not easy to be different. The thrust is generated at the optimum angle of attack at the radius. The vertical axis type fan does not have the above problems, but the angle of attack formed between the fan blade and the wind direction changes with the rotation motion, and cannot be maintained at the optimal angle of attack to increase the output power of the fan.

此外,不論水平軸式或垂直軸式風機,旋轉式的週期性運動會產生明顯噪音,且高速旋轉時形成的低壓導致小型飛行生物死亡,汙染環境、破壞生態事件頻傳。In addition, regardless of the horizontal axis or vertical axis fan, the rotary periodic motion will produce significant noise, and the low pressure formed during high-speed rotation will cause small flying organisms to die, pollute the environment and destroy ecological events.

因此,本發明之目的,即在提供一種改善現有技術的用於發電的線性往復式流體動力轉換系統。Accordingly, it is an object of the present invention to provide a linear reciprocating fluid power conversion system for power generation that improves the prior art.

有關本發明之前述及其他技術內容、特點與功效,在以下配合參考圖式之四個較佳實施例的詳細說明中,將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

在本發明被詳細描述之前,要注意的是,在以下的說明內容中,類似的元件是以相同的編號來表示。Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

參閱圖1,本發明用於發電的線性往復式流體動力轉換系統之第一較佳實施例置於一空氣流場中,該流場的假設的入流方向H為由前往後,然而實際上假設的入流方向H會受環境因素影響而有變化。本實施例包含一與發電系統(圖未示)連接的線性移動裝置1、一流體動力轉換裝置2、二大致上由前往後延伸且左右相間隔的側壁4,及一翼片轉向裝置3。Referring to Fig. 1, a first preferred embodiment of the linear reciprocating fluid power conversion system for power generation of the present invention is placed in an air flow field, the assumed inflow direction H of the flow field is determined by the going, but actually assumed The inflow direction H will vary depending on environmental factors. The embodiment comprises a linear moving device 1 connected to a power generation system (not shown), a fluid power converting device 2, two side walls 4 extending substantially from the rear to the left and right, and a vane steering device 3.

該線性移動裝置1包括一與該流場的假設的入流方向H垂直且沿一第一方向J1延伸的第一線性軸11,及一可線性往復移動地安裝於該第一線性軸11上的第一移動件12。本實施中該線性移動裝置1還包括一第二線性軸13及一第二移動件14,藉此提高穩固性,但不以此為限。該第二線性軸13位於該流體動力轉換裝置2相反於該第一線性軸11所在的一側,且與該第一線性軸11平行並相間隔。也就是如圖1所示,該第一線性軸11與第二線性軸13一上一下地設置在流體動力轉換裝置2的上方與下方。該第二移動件14可線性往復移動地安裝於該第二線性軸13上。The linear moving device 1 includes a first linear axis 11 that is perpendicular to the assumed inflow direction H of the flow field and extends along a first direction J1, and a linearly reciprocally mounted to the first linear axis 11 The first moving member 12 on the upper. In the present embodiment, the linear moving device 1 further includes a second linear shaft 13 and a second moving member 14, thereby improving the stability, but not limited thereto. The second linear axis 13 is located on a side of the fluid dynamic conversion device 2 opposite to the first linear axis 11 and is parallel and spaced apart from the first linear axis 11. That is, as shown in FIG. 1, the first linear shaft 11 and the second linear shaft 13 are disposed above and below the fluid power conversion device 2 one above another. The second moving member 14 is mounted on the second linear shaft 13 in a linear reciprocating manner.

該流體動力轉換裝置2包括一與該第一移動件12及該第二移動件14連接的第一翼片21。定義一與該第一方向J1垂直且與該流場的假設的入流方向H垂直的第二方向J2。在本實施例中,該第一移動件12及該第二移動件14以一沿第二方向J2延伸的轉軸15彼此連接,該第一翼片21設置在該轉軸15上,因此大致呈直立。The fluid power conversion device 2 includes a first fin 21 connected to the first moving member 12 and the second moving member 14. A second direction J2 perpendicular to the first direction J1 and perpendicular to the assumed inflow direction H of the flow field is defined. In this embodiment, the first moving member 12 and the second moving member 14 are connected to each other by a rotating shaft 15 extending in the second direction J2. The first flap 21 is disposed on the rotating shaft 15, and thus is substantially erect. .

配合參閱圖2,第一翼片21在垂直該第二方向J2的一第一剖面對稱於一第一中心弦線G1,該第一中心弦線G1連接該第一翼片21的前端與後端。若因特殊應用需求,例如需令往、復運動的過程產生不相等的升力,則該第一翼片21亦可不對稱於該第一中心弦線G1。該第一中心弦線G1與該流場的假設的入流方向H夾一可調整的第一角度δ1。第一翼片21線性位移以及改變角度相關技術容後說明。Referring to FIG. 2, the first fin 21 is symmetrical to a first central chord G1 in a first section perpendicular to the second direction J2, and the first center chord G1 is connected to the front end and the rear of the first fin 21 end. The first fin 21 may also be asymmetric with respect to the first center chord G1 if, for example, the process of the reciprocating and complex motions is required to produce unequal lift. The first central chord G1 and the hypothetical inflow direction H of the flow field are each clamped by an adjustable first angle δ1. The first fin 21 is linearly displaced and the angle-changing technique is described later.

該等側壁4位於該流體動力轉換裝置2移動範圍的左右兩相反側。該翼片轉向裝置3包括一本體31、一限位件32,及二分別設於該等側壁4上的第一彈性元件33。該本體31具有一與該第一移動件12連接的基部311及一例如使用套管連接該基部311而可相對於該基部311前後移動的活動部312。該活動部312形成有一弧形的第一導槽313。該第一翼片21頂面形成有一沿著該第一中心弦線G1延伸的第二導槽211,供該限位件32滑動。該限位件32可滑動地設於該第二導槽211上,並穿置於該活動部312的第一導槽313中。該弧形的第一導槽313有其長度限制,該限位件32只能運動於該第一導槽313的兩端點間。因該限位件32為可滑動地設於第二導槽211上,故可配合活動部312的第一導槽313,而隨著該第一翼片21繞著該轉軸15轉動。在流場中,流體會推動第一翼片21繞著該轉軸15轉動而將該限位件32帶動到該第一導槽313的其中一端點,並且在無其他外力的作用下持續固定於該端點。The side walls 4 are located on opposite sides of the left and right sides of the range of movement of the fluid power conversion device 2. The flap steering device 3 includes a body 31, a limiting member 32, and two first elastic members 33 respectively disposed on the side walls 4. The body 31 has a base portion 311 connected to the first moving member 12 and a movable portion 312 movable forward and backward relative to the base portion 311, for example, by connecting the base portion 311 with a sleeve. The movable portion 312 is formed with an arcuate first guiding groove 313. The top surface of the first fin 21 is formed with a second guiding groove 211 extending along the first central chord G1 for the limiting member 32 to slide. The limiting member 32 is slidably disposed on the second guiding slot 211 and is disposed in the first guiding slot 313 of the movable portion 312. The curved first guiding groove 313 has a length limit, and the limiting member 32 can only move between the two ends of the first guiding groove 313. Since the limiting member 32 is slidably disposed on the second guiding groove 211, the first guiding groove 313 of the movable portion 312 can be engaged with the first wing piece 21 to rotate around the rotating shaft 15. In the flow field, the fluid will push the first flap 21 to rotate around the rotating shaft 15 to drive the limiting member 32 to one end of the first guiding groove 313, and is continuously fixed to the first guiding groove 313 without any external force. The endpoint.

參閱圖2與圖3,調整該活動部312前後移動可控制該第一導槽313相對靠近與相對遠離該基部311,該第一導槽313相對靠近該基部311所提供該第一角度δ1的可調範圍大於該第一導槽313相對遠離該基部311所提供該第一角度δ1的可調範圍。該活動部312可調整到與該基部311相距需求的距離的位置後,固定保持該距離。可經由計算得到線性位移效率最佳化的最大第一角度δ1,並藉由調整該活動部312而實現第一角度δ1範圍之控制,使得產生升力時,除往復折返點外,在移動過程中能保持第一角度δ1不變。前述最大第一角度δ1與線性位移最佳化的計算方式非本發明主要技術特徵所在,因此本文中未加以說明。Referring to FIG. 2 and FIG. 3, adjusting the movable portion 312 to move forward and backward can control the first guiding groove 313 to be relatively close to and away from the base portion 311. The first guiding groove 313 is relatively close to the base portion 311 and provides the first angle δ1. The adjustable range is greater than the adjustable range of the first guiding groove 313 relative to the first angle δ1 provided by the base 311. The movable portion 312 can be adjusted to maintain the distance after being adjusted to a position at a required distance from the base portion 311. The maximum first angle δ1 optimized by the linear displacement efficiency can be obtained by calculation, and the control of the first angle δ1 range is realized by adjusting the movable portion 312, so that when the lift is generated, in addition to the reciprocating turn-back point, during the movement Can maintain the first angle δ1 unchanged. The calculation method of the aforementioned maximum first angle δ1 and linear displacement optimization is not the main technical feature of the present invention, and therefore is not described herein.

該等第一彈性元件33供該第一翼片21在移動至鄰近該等側壁4處時抵觸,以使該第一翼片21改變方向。The first elastic members 33 are adapted to interfere with the first flap 21 when moved adjacent to the side walls 4 to redirect the first flap 21.

本實施例中,第一彈性元件33使第一翼片21改變方向的機制為:第一彈性元件33受壓的最大力量為第一翼片21所產生的升力,在第一彈性元件33受壓的過程中,第一翼片21與假設的入流方向H的夾角亦逐漸改變,因而升力逐漸減小,故第一彈性元件33有足夠的彈力推動第一翼片21往反方向轉動。換言之,該第一角度δ1由最大第一角度δ1逐漸降低,接下來,只要第一翼片21轉向至超過平行於該流場的假設的入流方向H的0°的第一角度δ1的位置,則該流場的流體即可沿假設的入流方向H推動第一翼片21轉動至反方向的最大第一角度δ1的位置。In this embodiment, the mechanism for the first elastic member 33 to change the direction of the first flap 21 is that the maximum force of the first elastic member 33 is the lift generated by the first flap 21, and the first elastic member 33 is subjected to the lift. During the pressing process, the angle between the first fin 21 and the assumed inflow direction H is also gradually changed, and thus the lift force is gradually reduced, so that the first elastic member 33 has sufficient elastic force to push the first flap 21 to rotate in the reverse direction. In other words, the first angle δ1 is gradually decreased by the maximum first angle δ1, and then, as long as the first fin 21 is turned to a position exceeding the first angle δ1 of 0° parallel to the assumed inflow direction H of the flow field, Then, the fluid of the flow field can push the first fin 21 to rotate to the position of the maximum first angle δ1 in the opposite direction along the assumed inflow direction H.

本實施例之第一彈性元件33包括一套筒331、一容設於該套筒331內的第一壓縮彈簧332、一抵觸該第一壓縮彈簧332且部分伸出該套筒331的桿件333,及一連接於桿件333外端且供第一翼片21抵觸的滾輪334,藉此提供強固的彈性結構設計。The first elastic member 33 of the embodiment includes a sleeve 331 , a first compression spring 332 received in the sleeve 331 , and a rod member that protrudes from the first compression spring 332 and partially protrudes from the sleeve 331 . 333, and a roller 334 connected to the outer end of the rod 333 for the first flap 21 to collide, thereby providing a strong elastic structural design.

參閱圖2與圖4,在該流場的流體流經該第一翼片21時,對該第一翼片21產生升力而帶動轉軸15使該第一移動件12及第二移動件14分別在該第一線性軸11及第二線性軸13上往該第一方向J1或相反於第一方向J1移動。在本實施例所述升力,非指第一翼片21能藉此上升或下降,以圖1所示的方向來說,第一翼片21是藉由升力而產生左右位移。當第一翼片21移動至鄰近右側的側壁4處,抵觸相對應的第一彈性元件33而改向,帶動該第一移動件12及第二移動件14分別在該第一線性軸11及第二線性軸13上往該第一方向J1移動。Referring to FIG. 2 and FIG. 4, when the fluid of the flow field flows through the first fin 21, a lift force is generated on the first fin 21 to drive the rotating shaft 15 to make the first moving member 12 and the second moving member 14 respectively. The first linear axis 11 and the second linear axis 13 move toward the first direction J1 or opposite to the first direction J1. In the lift described in this embodiment, it is not indicated that the first flap 21 can be raised or lowered by this. In the direction shown in Fig. 1, the first flap 21 is displaced left and right by the lift. When the first flap 21 is moved to the side wall 4 adjacent to the right side, the first elastic member 33 is reversing against the corresponding first elastic member 33, and the first moving member 12 and the second moving member 14 are respectively driven on the first linear shaft 11 And moving on the second linear axis 13 toward the first direction J1.

參閱圖5,該第一翼片21在移動至鄰近左側的側壁4處時,抵觸相對應的第一彈性元件33而改向,帶動該第一移動件12及第二移動件14分別在該第一線性軸11及第二線性軸13上往相反於該第一方向J1移動,接著又回復至如圖4的狀態,如此往復移動。Referring to FIG. 5, the first flap 21 is reversing against the corresponding first elastic member 33 when moving to the side wall 4 adjacent to the left side, and the first moving member 12 and the second moving member 14 are respectively driven. The first linear axis 11 and the second linear axis 13 move opposite to the first direction J1, and then return to the state of FIG. 4, and thus reciprocate.

因此,空氣流場中氣流的動能,被轉換為該第一移動件12與該第二移動件14的動能,再經發電系統轉換為電能而提供電力。Therefore, the kinetic energy of the airflow in the air flow field is converted into the kinetic energy of the first moving member 12 and the second moving member 14, and is converted into electric energy by the power generation system to supply electric power.

參閱圖6,本發明用於發電的線性往復式流體動力轉換系統的第二較佳實施例與第一較佳實施例大致相同,其差異在於,第一較佳實施例中的各該第一彈性元件33,在第二較佳實施例中,由一主動式彈性元件35替換,該主動式彈性元件35包括相互連接的一橢圓轉輪351及一端點開關352。Referring to Figure 6, a second preferred embodiment of the linear reciprocating fluid power conversion system for power generation of the present invention is substantially identical to the first preferred embodiment, with the difference that each of the first preferred embodiments The elastic member 33, in the second preferred embodiment, is replaced by an active resilient member 35 comprising an elliptical wheel 351 and an end switch 352 that are interconnected.

當第一翼片21往第一方向J1(如圖6箭頭所示)移動,將會壓迫橢圓轉輪351,致使端點開關352產生通路,而如圖7所示啟動橢圓轉輪351轉動。橢圓轉輪351的長軸、短軸的長度差大於等於主動式彈性元件35要使第一翼片21轉向所需推動的距離,故橢圓轉輪351轉動的過程,即可推動第一翼片21轉向。When the first flap 21 is moved in the first direction J1 (shown by the arrow in Fig. 6), the elliptical wheel 351 will be pressed, causing the end point switch 352 to make a path, and the elliptical wheel 351 is rotated as shown in FIG. The length difference between the major axis and the minor axis of the elliptical wheel 351 is greater than or equal to the distance that the active elastic member 35 is required to turn the first fin 21 to be pushed. Therefore, the process of rotating the elliptical wheel 351 can push the first fin. 21 turns.

第一翼片21轉向後,會往相反於第一方向J1(如圖8箭頭所示)移動,橢圓轉輪351的受壓現象解除,端點開關352產生斷路,橢圓轉輪351回復至起始位置。至此,完成翼片轉向的動作。After the first flap 21 is turned, it will move in the opposite direction to the first direction J1 (as indicated by the arrow in FIG. 8), the pressure phenomenon of the elliptical runner 351 is released, the end point switch 352 is broken, and the elliptical runner 351 is restored. Starting position. At this point, the action of the flap turning is completed.

參閱圖9,本發明用於發電的線性往復式流體動力轉換系統的第三較佳實施例與第一較佳實施例大致相同,其差異在於,以假設的入流方向H同樣為由前往後來說,第一線性軸11與第二線性軸13是上下延伸,且一左一右地設置在流體動力轉換裝置2的左方與右方,連接該第一移動件12及該第二移動件14的轉軸15為左右延伸,該第一翼片21因此大致呈水平設置。整體來說,不同於第一較佳實施例的流體動力轉換裝置2的移動方式為左右走向,第三較佳實施例為上下走向,適合應用在液體流場中,例如海洋、潮汐區的環境,應用於洋流發電或潮汐發電。海洋、河川的流場特性為水面寬大於水深,故適合該第一翼片21以水平方向展開,可不受水深限制。且流體的密度大,可調整翼片的重量,使之與水的密度相等,則翼片的運動不受重力影響,往上、往下、皆可以相同升力運動,有利於上下走向的反復運動。Referring to Figure 9, the third preferred embodiment of the linear reciprocating fluid power conversion system for power generation of the present invention is substantially the same as the first preferred embodiment, with the difference that the assumed inflow direction H is also The first linear axis 11 and the second linear axis 13 extend up and down, and are disposed left and right on the left and right sides of the fluid power conversion device 2, and connect the first moving member 12 and the second moving member The shaft 15 of the 14 extends left and right, and the first flap 21 is thus disposed substantially horizontally. In general, the movement mode of the fluid power conversion device 2 different from the first preferred embodiment is a left-right direction, and the third preferred embodiment is an up-and-down direction, which is suitable for application in a liquid flow field, such as an environment of the ocean and the tidal zone. It is applied to ocean current power generation or tidal power generation. The flow field characteristics of the ocean and the river are such that the water surface is wider than the water depth, so that the first fin 21 is suitable to be horizontally unfolded, and is not limited by the water depth. Moreover, the density of the fluid is large, and the weight of the airfoil can be adjusted to be equal to the density of the water, so that the movement of the airfoil is not affected by gravity, and the same lifting force can be moved upwards and downwards, which is favorable for the repeated movement of the upper and lower directions. .

參閱圖10,本發明用於發電的線性往復式流體動力轉換系統的第四較佳實施例與第一較佳實施例大致相同,其差異在於,該流體動力轉換裝置2還包括一設於該第一翼片21後方的第二翼片22、一連接該第一翼片21與該第二翼片22後端的第二彈性元件23,及一直桿221。Referring to FIG. 10, a fourth preferred embodiment of the linear reciprocating fluid power conversion system for generating electricity of the present invention is substantially the same as the first preferred embodiment, except that the fluid power conversion device 2 further includes a A second flap 22 behind the first flap 21, a second elastic member 23 connecting the first flap 21 and the rear end of the second flap 22, and a straight rod 221.

在飛機航行的應用中,第二翼片的使用,主要是於飛機起飛、降落時,因飛行速度較低,故需提升機翼升力係數,以提高機翼所產生升力。使用第二翼片,雖能大幅提升升力係數,卻也會於主要入流方向增加阻力,故飛機起飛後,會將第二翼片收起,以減少飛行阻力。在本實施例中,入流方向的阻力增大對發電效率並無不良影響,但升力增加則可提升發電效率,故值得採用第二翼片。In the application of aircraft navigation, the use of the second wing is mainly due to the fact that when the aircraft takes off and land, the flight speed is low, so the lift coefficient of the wing needs to be increased to increase the lift generated by the wing. The use of the second wing, although significantly increasing the lift coefficient, will also increase the resistance in the main inflow direction, so after the aircraft takes off, the second wing will be retracted to reduce flight resistance. In the present embodiment, the increase in the resistance in the inflow direction has no adverse effect on the power generation efficiency, but the increase in the lift force can increase the power generation efficiency, so it is worthwhile to use the second fin.

本實施例第二翼片22遠小於第一翼片21,設置第二翼片22的主要目的在於有效提升整體翼面架構(含第一翼片21與第二翼片22)的總升力係數、與降低產生最大升力時的第一角度δ1。The second fin 22 of the present embodiment is much smaller than the first fin 21, and the main purpose of providing the second fin 22 is to effectively increase the total lift coefficient of the overall airfoil structure (including the first fin 21 and the second fin 22). And reducing the first angle δ1 when the maximum lift is generated.

該第二翼片22可以一前端轉軸222樞接於第一翼片21後方,也可與第一翼片21分隔排列設置。該樞接方式及分隔排列設置的方式非本發明重點,不在此贅述。在本實施例中該第二彈性元件23也可設置為連接該第一移動件12與該第二翼片22後端。該翼片轉向裝置3還包括二分別設於該等側壁4上的推擋件34。The second flap 22 can be pivotally connected to the rear of the first flap 21 or can be spaced apart from the first flap 21 . The manner of the pivotal connection and the arrangement of the partitions is not the focus of the present invention and will not be described herein. In this embodiment, the second elastic member 23 can also be disposed to connect the first moving member 12 and the rear end of the second flap 22. The flap steering device 3 further includes two pushers 34 respectively disposed on the side walls 4.

該第二翼片22垂直該第二方向J2(穿入紙面)的第二剖面對稱於一第二中心弦線G2,且該第二中心弦線G2與該第一中心弦線G1夾一可調整的第二角度δ2,因而亦與該流場的假設的入流方向H夾一可調整第三角度δ3。該直桿221設於該第二翼片22的上側,並沿其相對應的側面的第二中心弦線G2延伸。在本實施例中,該第二翼片22還可包含一設於該第二翼片22下側的直桿221,及二相對應的推擋件34,使該第二翼片22轉向動作更為穩定。The second section of the second flap 22 perpendicular to the second direction J2 (penetrating into the paper surface) is symmetrical to a second center string G2, and the second center string G2 is sandwiched by the first center string G1. The adjusted second angle δ2, and thus also the assumed inflow direction H of the flow field, is adjustable by a third angle δ3. The straight rod 221 is disposed on the upper side of the second fin 22 and extends along a second center chord G2 of its corresponding side. In this embodiment, the second flap 22 can further include a straight rod 221 disposed on the lower side of the second flap 22, and two corresponding pushers 34 to steer the second flap 22 More stable.

本實施例之第二彈性元件23包括二分別樞接於該第二翼片22尾端與第一翼片21後段位置的樞桿231、連接於該二樞桿231之間的第二壓縮彈簧232,及套接於該二樞桿231與第二壓縮彈簧232之外的套管233。在該流場的流體流經該第一翼片21及第二翼片22時,對該第一翼片21及第二翼片22產生升力而沿著該第一方向J1移動,藉由該第二彈性元件23與該第一翼片21的連接,保持該第二角度δ2在移動過程中不變。The second elastic member 23 of the present embodiment includes two pivot rods 231 pivotally connected to the rear end of the second flap 22 and the rear end of the first flap 21, and a second compression spring connected between the two pivot rods 231. 232, and a sleeve 233 that is sleeved outside the two pivots 231 and the second compression spring 232. When the fluid in the flow field flows through the first fin 21 and the second fin 22, the first fin 21 and the second fin 22 generate lift force and move along the first direction J1, by the The connection of the second elastic element 23 to the first flap 21 keeps the second angle δ2 constant during the movement.

配合參閱圖11與圖12,該等推擋件34供該第二翼片22的該直桿221在移動至鄰近該等側壁4處時抵觸,以使該第二翼片22改變方向,進而使得該流體動力轉換裝置2於該等側壁4間往復運動。Referring to FIG. 11 and FIG. 12, the pushing members 34 are adapted to the bottom rod 221 of the second flap 22 to move adjacent to the side walls 4, so that the second flap 22 changes direction, thereby The hydrodynamic converter 2 is caused to reciprocate between the side walls 4.

使用推擋件34改變第二翼片22的第二中心弦線G2與第一中心弦線G1所夾的第二角度δ2、並以第二彈性元件23保持第二角度δ2的可行性分析如下:第一翼片21前端受第一彈性元件33推力使第一角度δ1改變時,此第一彈性元件33的推力對第一翼片21施加一繞轉軸15轉動的力矩,則第一翼片21尾端亦受同方向轉動的力矩作用。第二翼片22的前端轉軸222設置於第一翼片21的尾端,故第一翼片21轉動時,第二翼片22的前端亦受到相同轉向的力矩。此第一翼片21產生的力矩遠大於轉動第二翼片22所需的力矩,故第二翼片22處的推擋件34可順利的令第二翼片22轉向。只要由第二彈性元件23的彈力相對於第二翼片22的前端轉軸222所產生的力矩大於第二翼片22升力所產生的力矩、且小於第一翼片21的升力相對於與第一翼片21連接的轉軸15所產生的力矩,即可令第二翼片22隨著第一翼片21的第一角度δ1改變而順利地改變第二角度δ2,並於第二角度δ2改變後,保持該第二角度δ2以令第一移動件12往反方向運動。The feasibility of using the pusher 34 to change the second angle δ2 of the second center chord G2 of the second fin 22 and the first center chord G1 and maintaining the second angle δ2 with the second elastic member 23 is as follows When the front end of the first flap 21 is changed by the first elastic member 33 to change the first angle δ1, the thrust of the first elastic member 33 applies a moment about the rotation of the rotating shaft 15 to the first flap 21, and the first flap The end of 21 is also affected by the moment of rotation in the same direction. The front end shaft 222 of the second flap 22 is disposed at the trailing end of the first flap 21, so that the front end of the second flap 22 is also subjected to the same turning moment when the first flap 21 is rotated. The moment generated by the first flap 21 is much greater than the torque required to rotate the second flap 22, so that the pusher 34 at the second flap 22 smoothly steers the second flap 22. As long as the moment generated by the elastic force of the second elastic member 23 relative to the front end shaft 222 of the second flap 22 is greater than the moment generated by the lift of the second flap 22 and smaller than the lift of the first flap 21 relative to the first The moment generated by the rotating shaft 15 connected to the flap 21 can cause the second flap 22 to smoothly change the second angle δ2 as the first angle δ1 of the first flap 21 changes, and after the second angle δ2 is changed The second angle δ2 is maintained to move the first moving member 12 in the opposite direction.

同樣的,第二翼片22的第二角度δ2的改變與保持第二角度δ2的設置,可有多種不同設計,然以此種被動式的設計最為簡單。Similarly, the change of the second angle δ2 of the second fin 22 and the setting of maintaining the second angle δ2 can have a variety of different designs, but the passive design is the simplest.

參閱圖13,以下說明本發明用於發電的線性往復式流體動力轉換系統的理論基礎以及可產生的效益。考慮一水平設置的翼面5,若流體的水平入流速度為u,翼面5受升力作用,往上升的速度為v,則流體相對於翼面5會有往下的相對流速v,而合成流速(resultant velocity)為w,合成流速與水平的夾角為β。此合成流速與翼面5所夾的攻角(angle of attack)為α,則翼面5的仰角(pitch angle)為θ=α+β。因流場方向、流速隨時變動,上述各速度及α角、β角因此會隨流場變化而變,由此角度關係可知,可藉由調整翼面5的仰角θ以保持翼面5於最佳攻角α。Referring to Figure 13, the theoretical basis and the benefits that can be produced by the linear reciprocating fluid power conversion system for power generation of the present invention are described below. Considering a horizontally disposed airfoil 5, if the horizontal inflow velocity of the fluid is u, the airfoil 5 is subjected to lift, and the upward velocity is v, the fluid has a relative flow velocity v relative to the airfoil 5, and is synthesized. The resultant velocity is w, and the angle between the synthetic flow rate and the level is β. The angle of attack of the resultant flow velocity with the airfoil 5 is α, and the pitch angle of the airfoil 5 is θ = α + β. Since the flow direction and the flow velocity fluctuate at any time, the above-mentioned respective speeds, the α angle and the β angle change with the flow field, and thus the angular relationship can be known by adjusting the elevation angle θ of the airfoil 5 to maintain the airfoil 5 at the most Good angle of attack α.

翼面5受合成入流速度為w的流體作用,產生垂直於w入流方向的升力L與平行於入流方向的阻力D,此兩作用力(L與D)在垂直軸方向的分量為Lcosβ-Dsinβ=ρw2 A(CL cosβ-CD sinβ)=ρw2 ACη ,此處的Cη =CL cosβ-CD sinβ,CL 與CD 分別為此翼面5在攻角為α時的升力係數與阻力係數,A則為翼面5的投影面積,A=b×c,b為翼面5寬度(width)(圖未示),c為翼面5弦長(chord length)。The airfoil 5 is subjected to a fluid having a synthetic inflow velocity w, and generates a lift L perpendicular to the w inflow direction and a resistance D parallel to the inflow direction. The components of the two forces (L and D) in the vertical axis direction are Lcosβ-Dsinβ. = Ww 2 A(C L cosβ-C D sinβ)= Ρw 2 AC η , where C η =C L cosβ-C D sinβ, C L and C D are the lift coefficient and drag coefficient of the airfoil 5 at an angle of attack α respectively, and A is the airfoil 5 The projected area, A = b × c, b is the width of the airfoil 5 (not shown), and c is the chord length of the airfoil.

翼面5所受升力在垂直方向的分量為Lη =ρw2 ACη ,翼面5受此升力,在垂直方向的運動速度為v=w(sinβ),此垂直方向運動遭受的形狀阻力為Dp =Cp ρv2 Acosθ=Cp ρ(wsinβ)2 Acosθ,Acosθ為翼面5面積在垂直方向的分量,故翼面5在垂直方向的淨作用力為Lη -Dp =ρw2 A(Cη -Cp sin2 βcosθ)。翼面5受此淨作用力,在垂直方向以v=w(sinβ)的速度運動,則此翼面5可輸出The component of the lift of the airfoil 5 in the vertical direction is L η = Ρw 2 AC η , the airfoil 5 is subjected to this lift, and the moving speed in the vertical direction is v=w(sinβ), and the vertical direction motion suffers from the shape resistance D p =C p Ρv 2 Acosθ=C p ρ(wsinβ) 2 Acos θ, Acos θ is the component of the airfoil 5 area in the vertical direction, so the net force of the airfoil 5 in the vertical direction is L η -D p = w w 2 A(C η -C p sin 2 βcos θ). The airfoil 5 is subjected to this net force and moves at a speed of v=w(sinβ) in the vertical direction, and the airfoil 5 can output

Cp sin2 βcos(α+β))的功率。若欲求解得可輸出最佳功率的流速角β,則可令=0,以求得β角度。一般而言,翼面5的CL >>CD ,在此先做初步估算,可將CD 的影響忽略不計,故Cη =CL cosβ,則輸出功率的方程式可簡化為P=ρw3 Asinβ(CL cosβ-Cp sin2 βcos(α+β)),推導=0的關係式,可得The power of C p sin 2 βcos(α+β)). If you want to solve the flow rate angle β that can output the best power, you can make =0 to find the β angle. In general, the C L >>C D of the airfoil 5 is initially estimated here, and the influence of C D can be neglected. Therefore, C η =C L cosβ, the equation of output power can be simplified to P= Ρw 3 Asinβ(C L cosβ-C p sin 2 βcos(α+β)), derivation =0 relationship, available

cosβ(CL cosβ-Cp sin2 βcos(α+β))+sinβ[-CL sinβ-2Cp sinβcosβcos(α+β)+Cp sin2 βsin(α+β)]=0Cosβ(C L cosβ-C p sin 2 βcos(α+β))+sinβ[-C L sinβ-2C p sinβcosβcos(α+β)+C p sin 2 βsin(α+β)]=0

組合後可得Available after combination

CL (cos2 β-sin2 β)-3Cp sin2 βcosβcos(α+β)+Cp sin3 βsin(α+β)=0C L (cos 2 β-sin 2 β)-3C p sin 2 βcosβcos(α+β)+C p sin 3 βsin(α+β)=0

Therefore

CL cos2β-3Cp sin2 βcosβcos(α+β)+Cp sin3 βsin(α+β)=0C L cos2β-3C p sin 2 βcosβcos(α+β)+C p sin 3 βsin(α+β)=0

假設所使用的翼形,在攻角為α=15°時,其升力係數CL 1.65,而平板垂直於入流速度方向運動的阻力係數為Cp 2.00,則由試誤法(Try and error)可求解得β35.8°,則v=w(sin35.8°)=0.585w,或v=0.721u,此時的功率輸出係數sinβ(CL cosβ-Cp sin2 βcos(α+β))=0.530。若入流速度所涵蓋的面積為A,則總入流能量為ρw3 A,而輸出功率為P=ρw3 Asinβ(CL cosβ-Cp sin2 βcos(α+β))=0.53ρw3 A,可知在此條件下,此翼面5的輸出效率為0.53或53%。Assume that the wing shape used has a lift coefficient C L when the angle of attack is α=15°. 1.65, and the resistance coefficient of the plate moving perpendicular to the inflow velocity is C p 2.00, then try and error can be solved by β 35.8°, then v=w(sin35.8°)=0.585w, or v=0.721u, at which time the power output coefficient sinβ(C L cosβ-C p sin 2 βcos(α+β))=0.530. If the area covered by the inflow velocity is A, the total inflow energy is Ww 3 A, and the output power is P= Ρw 3 Asinβ(C L cosβ-C p sin 2 βcos(α+β))=0.53 Ρw 3 A, it can be seen that under this condition, the output efficiency of the airfoil 5 is 0.53 or 53%.

在上述的升力估算中,若考慮CD sinβ的影響,則總升力會稍降,由=0的條件所求解得的β角度會稍異於35.8°,但不會相去太遠,因CL >>CD 。又由此計算結果可知,因翼面5作用產升的合成速度w僅稍大於入流速度u,w1.233u,對環境流場不會造成太大變化,因而可有效減少環境噪音、或壓力急遽變化等不良影響。In the above lift estimation, if the influence of C D sinβ is considered, the total lift will decrease slightly. The β angle obtained by the condition of =0 will be slightly different from 35.8°, but will not be too far apart, because C L >>C D . From this calculation result, it is known that the composite speed w due to the action of the airfoil 5 is only slightly larger than the inflow velocity u, w. 1.233u, will not cause too much change to the environmental flow field, thus effectively reducing environmental noise, or sudden changes in pressure and other adverse effects.

綜上所述,該流體動力轉換裝置2以線性速度移動,故該第一翼片21與第二翼片22沿著第二方向J2的不同位置處,均以相等線性速度運動,因此不需改變第一中心弦線G1與第二中心弦線G2的弦長、不須縮減面積,而可採用等弦長的翼片。本發明還可依計算結果調整最佳第一角度δ1,使得升力及其產生的推力達最大化,且產生升力時,除往復折返點外,在移動過程中能保持第一角度δ1不變,而以最大面積、最佳推力、最佳第一角度δ1進行流體動力轉換輸出。且線性運動所產生的噪音,遠低於旋轉運動所產生的噪音,誤擊生物的可能性亦降低許多,故確實能達成本發明之目的。In summary, the fluid power conversion device 2 moves at a linear speed, so that the first fin 21 and the second fin 22 move at equal linear speeds at different positions along the second direction J2, so The chord length of the first center chord G1 and the second center chord G2 is changed, and the area is not required to be reduced, and an chord-length fin may be used. The invention can also adjust the optimal first angle δ1 according to the calculation result, so that the lift force and the generated thrust force are maximized, and when the lift force is generated, the first angle δ1 can be maintained during the moving process except for the reciprocating turn-back point. The hydrodynamic conversion output is performed with the largest area, the optimal thrust, and the optimal first angle δ1. Moreover, the noise generated by the linear motion is much lower than the noise generated by the rotational motion, and the possibility of accidentally hitting the creature is also much reduced, so that the object of the present invention can be achieved.

惟以上所述者,僅為本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
