Description

葉片裝置Blade device

本發明是有關於一種葉片裝置，特別是指一種利用風力驅動而運轉的葉片裝置。The present invention relates to a blade device, and more particularly to a blade device that is driven by wind.

風力發電是一種運用自然界之風力驅動機械構件轉動，並將轉動動能轉換成電能的發電方式，相對於利用燃煤、石油等火力發電對環境造成的汙染較小。而影響風力發電的效率除了設置地點的風力大小外，如何將風力有效地引導及收集，讓葉片確實地受風驅動而轉動，此問題為業者一直改進之處。Wind power generation is a method of generating electricity by using natural wind to drive mechanical components to rotate and converting the rotational kinetic energy into electrical energy. Compared with coal, oil and other thermal power generation, wind power generation causes less pollution to the environment. In addition to the wind speed at the installation location, the efficiency of wind power generation is also affected by how to effectively guide and collect the wind so that the blades are actually driven by the wind and rotate. This problem has been continuously improved by the industry.

參閱圖1，一種現有的風力葉片裝置9，可受風力8驅轉，其結構主要包括一水平延伸的轉軸91，及數片由該轉軸91的徑向向外弧彎延伸的葉片92。該等葉片92是表面完整而沒有孔洞的長板片狀結構物，雖然位於該轉軸91上方的順風向的葉片92能順著所述風力8而驅動該轉軸91朝一旋轉方向93旋轉，但位於該轉軸91下方的逆風向的葉片92受到相同方向的所述風力8卻會對該轉軸91產生反方向的扭力，降低該等葉片帶動該轉軸91旋轉的效率。Referring to FIG. 1 , a conventional wind blade device 9 can be driven by wind force 8, and its structure mainly includes a horizontally extending shaft 91 and a plurality of blades 92 extending radially outward from the shaft 91 in an arc shape. The blades 92 are long plate-like structures with a complete surface and no holes. Although the blades 92 located above the shaft 91 in the windward direction can drive the shaft 91 to rotate in a rotation direction 93 along the wind force 8, the blades 92 located below the shaft 91 in the reverse windward direction will generate a torque in the opposite direction to the shaft 91 when subjected to the wind force 8 in the same direction, thereby reducing the efficiency of the blades driving the shaft 91 to rotate.

本發明之目的，是在提供一種能夠克服先前技術的至少一個缺點的葉片裝置。The object of the present invention is to provide a blade device that can overcome at least one disadvantage of the prior art.

於是，本發明葉片裝置，可受風力驅動而朝一運轉方向轉動，並包含一轉軸，及數個葉片模組。該等葉片模組連接該轉軸且彼此角度間隔，每一葉片模組包括一連接該轉軸且設有數個縱橫間隔排列的第一空間的格柵式葉片，及數個安裝於該格柵式葉片並分別對應設置於該等第一空間的開闔單元，每一開闔單元可開啟地遮蓋對應的該第一空間，並具有一連接該格柵式葉片的樞軸，及兩片樞接於該樞軸並背向該運轉方向往外延伸的開闔葉片；每一開闔單元可在一擋風狀態及一透風狀態切換，在該擋風狀態時，該等開闔葉片靠抵在該格柵式葉片上，並相配合遮蓋各別的該第一空間；在該透風狀態時，該等開闔葉片相互擺靠接近而使各別的該第一空間可透風。Therefore, the blade device of the present invention can be driven by wind to rotate in a running direction, and includes a rotating shaft and a plurality of blade modules. The blade modules are connected to the rotating shaft and spaced apart from each other at an angle. Each blade module includes a grid-type blade connected to the rotating shaft and provided with a plurality of first spaces spaced apart in the longitudinal and transverse directions, and a plurality of opening units installed on the grid-type blade and respectively arranged in the first spaces. Each opening unit can be opened to cover the corresponding first space and has a hinge connected to the grid-type blade. , and two opening blades pivotally connected to the pivot and extending outwardly in the opposite direction of the running direction; each opening unit can be switched between a wind-blocking state and a wind-ventilating state. In the wind-blocking state, the opening blades lean against the lattice blades and cooperate to cover the respective first spaces; in the wind-ventilating state, the opening blades are placed close to each other so that the respective first spaces can be ventilated.

本發明的功效在於：藉由該等格柵式葉片具有該等第一空間，再配合該等開闔單元可開啟地遮蓋對應的該等第一空間的結構設計。使該等葉片模組在受到風力吹動時，位於順向的葉片模組的該等開闔單元會遮蓋對應的該等第一空間，進而帶動該轉軸旋轉，位於逆向而無法有效帶動該轉軸旋轉的葉片模組的該等開闔單元會開啟對應的該等第一空間，減少逆向的風阻，進而增加風力帶動該葉片裝置旋轉的效率。The effect of the present invention is that the lattice-type blades have the first spaces, and the opening units can be opened to cover the corresponding first spaces. When the blade modules are blown by wind, the opening units of the blade modules located in the forward direction will cover the corresponding first spaces, thereby driving the shaft to rotate, and the opening units of the blade modules located in the reverse direction and unable to effectively drive the shaft to rotate will open the corresponding first spaces, thereby reducing reverse wind resistance and increasing the efficiency of the wind driving the blade device to rotate.

在本發明被詳細描述之前，應當注意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 should be noted that similar components are represented by the same reference numerals in the following description.

參閱圖2、3、4，本發明葉片裝置的一個第一實施例，可受風力F朝一運轉方向T旋轉，如圖4所示，所述風力F是由右往左，該運轉方向T是朝逆時針方向旋轉。該葉片裝置包含一個水平橫向延伸的轉軸1、兩個可轉動地套接安裝於該轉軸1上的葉片模組2，及數個沿該轉軸1的軸向間隔排列地圍繞該轉軸並連接於該等葉片模組2間的支架3。Referring to Figures 2, 3, and 4, a first embodiment of the blade device of the present invention can be rotated in a running direction T by wind force F. As shown in Figure 4, the wind force F is from right to left, and the running direction T is counterclockwise. The blade device includes a horizontally extending shaft 1, two blade modules 2 rotatably mounted on the shaft 1, and a plurality of brackets 3 arranged at intervals along the axial direction of the shaft 1 and surrounding the shaft and connected between the blade modules 2.

該等葉片模組2連接該轉軸1且彼此角度間隔，每一葉片模組2包括一個與該轉軸1連接的格柵式葉片21、數個安裝於該格柵式葉片21上的開闔單元22、數個安裝於該格柵式葉片21上的擺動葉片23，及一安裝於該格柵式葉片21上的固風片24。The blade modules 2 are connected to the rotating shaft 1 and are angularly spaced from each other. Each blade module 2 includes a grille blade 21 connected to the rotating shaft 1, a plurality of opening units 22 mounted on the grille blade 21, a plurality of swing blades 23 mounted on the grille blade 21, and a wind fixing blade 24 mounted on the grille blade 21.

每一格柵式葉片21是自該轉軸1朝背向該運轉方向T徑向往外弧彎延伸，並具有數個沿該轉軸1軸向延伸且沿該轉軸1徑向間隔排列的第一柵桿211，及數個沿該轉軸1徑向延伸且沿該轉軸1軸向間隔排列的第二柵桿212，該等第一柵桿211與該等第二柵桿212共同界定數個縱橫間隔排列的第一空間201與第二空間202。該等第一空間201是排列設置於該格柵式葉片21遠離該轉軸1的一側，該等第二空間202是排列設置於該格柵式葉片21靠近該轉軸1的一側。該等第一空間201的截面積大小是隨著遠離該轉軸1而逐漸變小，也就是說，離該轉軸1最遠的一側的該等第一空間201沿該轉軸1軸向排列的數量最多，隨著越往該轉軸1靠近的排列數量越少。Each lattice blade 21 extends radially outward from the shaft 1 in a direction opposite to the rotation direction T, and has a plurality of first fence rods 211 extending axially along the shaft 1 and arranged at intervals in the radial direction of the shaft 1, and a plurality of second fence rods 212 extending radially along the shaft 1 and arranged at intervals in the axial direction of the shaft 1. The first fence rods 211 and the second fence rods 212 together define a plurality of first spaces 201 and second spaces 202 arranged at intervals in the longitudinal and transverse directions. The first spaces 201 are arranged on the side of the lattice blade 21 far from the rotation axis 1, and the second spaces 202 are arranged on the side of the lattice blade 21 close to the rotation axis 1. The cross-sectional area of the first spaces 201 gradually decreases as they are farther away from the rotation axis 1, that is, the number of the first spaces 201 arranged axially along the rotation axis 1 is the largest on the side farthest from the rotation axis 1, and the number of the first spaces 201 arranged closer to the rotation axis 1 is smaller.

該等開闔單元22是可開啟地遮蓋該等第一空間201，每一開闔單元22具有一沿該轉軸1的徑向方向延伸並跨接固定在兩相鄰第一柵桿211間的樞軸221，及兩片樞接於該樞軸221並背向該運轉方向T往外延伸的開闔葉片222。每一開闔葉片222具有一個與對應的該樞軸221樞接呈環狀的外框223，及一固定在該外框223上且不透風的擋風片組224。該等開闔葉片222的長寬尺寸只需要剛好可遮蓋對應的該等第一空間201的大小，由於遠離該轉軸1的該等第一空間201的截面積相較於靠近該轉軸1的該等第一空間201的截面積小，因此設置於遠離該轉軸1的該等開闔葉片222的長寬尺寸相較於靠近該轉軸1的該等開闔葉片222的長寬尺寸小。The opening units 22 can be opened to cover the first spaces 201. Each opening unit 22 has a pivot 221 extending along the radial direction of the rotation axis 1 and straddling and fixed between two adjacent first fence rods 211, and two opening blades 222 pivoted to the pivot 221 and extending outwardly away from the rotation direction T. Each opening blade 222 has an outer frame 223 pivoted to the corresponding pivot 221 and in an annular shape, and a windproof sheet set 224 fixed to the outer frame 223 and impermeable. The length and width of the opening blades 222 only need to just cover the size of the corresponding first spaces 201. Since the cross-sectional area of the first spaces 201 far from the rotating shaft 1 is smaller than the cross-sectional area of the first spaces 201 close to the rotating shaft 1, the length and width of the opening blades 222 arranged far from the rotating shaft 1 are smaller than the length and width of the opening blades 222 close to the rotating shaft 1.

配合參閱圖5，每一擋風片組224具有數片層疊設置的擋風片225，且越遠離該轉軸1的該等擋風片組224的擋風片225數量越多。每一擋風片225是以例如帆布、石墨烯或其他高分子材料製成的可撓曲薄片，並具有一片本體226，及數條長向延伸且間隔排列於該片本體226的加強肋227。每一加強肋227的厚度大於各別的片本體226，且相鄰兩擋風片225的該等加強肋226的延伸方向彼此交錯，藉此組成較不易被風吹壞的結構。Referring to FIG. 5 , each wind shielding sheet set 224 has a plurality of wind shielding sheets 225 stacked in layers, and the wind shielding sheets 225 of the wind shielding sheet set 224 that are farther from the rotating shaft 1 are more numerous. Each wind shielding sheet 225 is a flexible sheet made of, for example, canvas, graphene or other polymer materials, and has a body 226 and a plurality of reinforcing ribs 227 that extend in the longitudinal direction and are arranged at intervals on the body 226. The thickness of each reinforcing rib 227 is greater than that of each body 226, and the extending directions of the reinforcing ribs 226 of two adjacent wind shielding sheets 225 are staggered with each other, thereby forming a structure that is less likely to be damaged by wind.

每一開闔單元22藉由該樞軸221與該等開闔葉片222的結構設計，可在一擋風狀態及一透風狀態間切換，在該擋風狀態時，該等開闔葉片222靠抵在該格柵式葉片21上，並相配合遮蓋各別的該第一空間201；在該透風狀態時，該等開闔葉片222相互擺靠接近而使各別的該第一空間201可透風。Each opening unit 22 can switch between a wind-blocking state and a wind-permeable state by means of the structural design of the hinge 221 and the opening blades 222. In the wind-blocking state, the opening blades 222 lean against the lattice blades 21 and cooperate to cover the respective first spaces 201; in the wind-permeable state, the opening blades 222 are placed close to each other so that the respective first spaces 201 can be ventilated.

該等擺動葉片23可擺動地垂掛設置於該等第一柵桿211，且分別對應該等第二空間202。每一擺動葉片23可採用與該等擋風片225相同之材料製成，且可在一擺靠於該格柵式葉片21而遮擋各別之第二空間202的關閉位置，以及一擺離該格柵式葉片21而使各別之第二空間202可透風的開啟位置間擺動。The swing blades 23 are swingably suspended on the first fence bars 211 and respectively correspond to the second spaces 202. Each swing blade 23 can be made of the same material as the wind shielding blades 225, and can be swung between a closed position leaning against the lattice blade 21 to shield the respective second space 202, and an open position swinging away from the lattice blade 21 to allow ventilation of the respective second space 202.

每一葉片模組2的該固風片24是安裝於對應之該格柵式葉片21的該等第一空間201與該等第二空間202的交界處，並沿該轉軸1的軸向長向延伸，且由該格柵式葉片21朝背向該運轉方向T往外弧彎延伸。The wind-fixing blade 24 of each blade module 2 is installed at the junction of the first spaces 201 and the second spaces 202 of the corresponding lattice blade 21, and extends along the axial length of the shaft 1, and extends from the lattice blade 21 to the outside in an arc shape away from the running direction T.

以圖4上方的該葉片模組2進行說明，該等支架3是圍繞該轉軸1並連接成四邊形且連接該等第二柵桿212，使鄰近該等支架3的該等擺動葉片23在原本要處於該關閉位置時不能靠抵於對應的該格柵式葉片21，而是靠抵於該等支架3上，形成一個由該等支架3的外周緣朝該格柵式葉片21延伸的斜面。Taking the blade module 2 in the upper part of FIG. 4 as an example, the brackets 3 surround the rotating shaft 1 and are connected to form a quadrilateral and are connected to the second fence rods 212, so that the swing blades 23 adjacent to the brackets 3 cannot lean against the corresponding grille blades 21 when they are originally in the closed position, but lean against the brackets 3, forming an inclined surface extending from the outer periphery of the brackets 3 toward the grille blades 21.

本實施例葉片裝置使用時，可藉由一架設裝置（圖未示）樞接於該轉軸1並架高使用。When the blade device of this embodiment is used, it can be pivotally connected to the rotating shaft 1 through a mounting device (not shown) and raised for use.

在受風力F驅動時，位於該轉軸1上方的該葉片模組2處於該風力F對該運轉方向T而言是順風向的位置，該等開闔葉片222受到所述風力F吹動而靠抵於該格柵式葉片21上，使該等開闔單元22切換至遮擋該等第一空間201的該擋風狀態，同時該等擺動葉片23也因為受到所述風力F吹動而靠抵於該格柵式葉片21，而處在遮蓋該等第二空間202的該關閉位置，該等開闔葉片222與該等擺動葉片23相互配合使該葉片模組2呈不透風的樣態。而最靠近該轉軸1的該等擺動葉片23是靠抵於該等支架3上並形成所述斜面，使靠近該轉軸1的風力F受到所述斜面引導向上作用於其他的擺動葉片23。該固風片24用於使遠離該轉軸1的風力F不會向下往該轉軸1流動，保持遠離該轉軸1的風力F作用於該等開闔葉片222。When driven by the wind force F, the blade module 2 located above the rotating shaft 1 is in a position along the wind direction of the wind force F with respect to the running direction T. The opening blades 222 are blown by the wind force F and lean against the lattice blades 21, so that the opening units 22 are switched to the wind-blocking state for shielding the first spaces 201. At the same time, the swing blades 23 are also blown by the wind force F and lean against the lattice blades 21, and are in the closed position for covering the second spaces 202. The opening blades 222 and the swing blades 23 cooperate with each other to make the blade module 2 airtight. The swing blades 23 closest to the shaft 1 are against the brackets 3 and form the inclined surface, so that the wind force F close to the shaft 1 is guided by the inclined surface to act upward on the other swing blades 23. The wind fixing blade 24 is used to prevent the wind force F away from the shaft 1 from flowing downward toward the shaft 1, and keep the wind force F away from the shaft 1 acting on the opening blades 222.

於此同時，位於該轉軸1下方的該葉片模組2處於該風力F對該運轉方向T而言是逆風向的位置，該等開闔葉片222受到所述風力F吹動而相互擺靠接近，使該等開闔單元22切換至使該等第一空間201可以透風的該透風狀態。同時該等擺動葉片23也因為受到所述風力F吹動而擺離於該格柵式葉片21，而處在開啟該等第二空間202的該開啟位置，該等開闔單元22與該等擺動葉片23相互配合使該葉片模組2呈透風的樣態，從而減少所述風力F施力於該葉片模組2的而造成相反於該運轉方向T的作用力，進而提高該葉片裝置收集所述風力F的效率。At the same time, the blade module 2 located below the rotating shaft 1 is in a position against the wind force F with respect to the running direction T, and the opening blades 222 are blown by the wind force F and are placed close to each other, so that the opening units 22 are switched to the ventilation state that allows the first spaces 201 to be ventilated. At the same time, the swing blades 23 are also swung away from the lattice blades 21 due to the blowing of the wind force F, and are in the open position for opening the second spaces 202. The opening units 22 and the swing blades 23 cooperate with each other to make the blade module 2 ventilated, thereby reducing the force exerted by the wind force F on the blade module 2 and causing a force opposite to the running direction T, thereby improving the efficiency of the blade device in collecting the wind force F.

要特別說明的是，每一擋風片組224的擋風片225層疊數量只要能夠承受所述風力F吹動而不破裂即可，設計上，根據該等葉片模組2通常離該轉軸1的徑向距離越遠的位置，所承受的風力F越大，因此將越遠離該轉軸1的該等擋風片組224的擋風片225數量越多，則其結構強度越強。且該等支架3的圍繞該轉軸1的形狀並不局限於四邊形，也可以是呈圓形地環繞該轉軸1，或是配合該等葉片模組2的數量而對應設計成多邊形，只要能供鄰近該轉軸1的該等擺動葉片23在該關閉位置時能貼靠並形成所述斜面即可。It should be particularly noted that the number of stacked wind shielding pieces 225 of each wind shielding piece group 224 only needs to be able to withstand the wind force F without breaking. In terms of design, the farther the blade modules 2 are from the rotating shaft 1 in radial direction, the greater the wind force F they withstand. Therefore, the farther the wind shielding pieces 225 of the wind shielding piece group 224 are from the rotating shaft 1, the stronger their structural strength will be. Furthermore, the shape of the brackets 3 surrounding the rotating shaft 1 is not limited to a quadrilateral, but may also be circularly surrounding the rotating shaft 1, or may be designed into a polygon corresponding to the number of the blade modules 2, as long as the swing blades 23 adjacent to the rotating shaft 1 can abut against and form the inclined surface in the closed position.

補充說明的是，該等葉片模組2通常離該轉軸1的徑向距離越遠的位置，所承受的風力F越大，因此將越遠離該轉軸1的該等開闔單元22的尺寸設計較小，減少該等開闔葉片222的受風面積，降低破損的機率，而將靠近該轉軸1的該等開闔單元22的尺寸設計較大，減少該等開闔單元22的數量，簡化該葉片裝置的整體設計。若該等開闔葉片222足夠承受所述風力F吹動而不破裂，也可不用調整設計該等開闔單元22的大小。It is to be noted that the blade modules 2 are usually farther from the rotating shaft 1 in radial direction, and the wind force F they bear is greater. Therefore, the size of the opening units 22 farther from the rotating shaft 1 is designed to be smaller, reducing the wind-receiving area of the opening blades 222 and reducing the probability of damage. The size of the opening units 22 close to the rotating shaft 1 is designed to be larger, reducing the number of the opening units 22 and simplifying the overall design of the blade device. If the opening blades 222 are sufficient to withstand the wind force F without breaking, the size of the opening units 22 does not need to be adjusted.

參閱圖6、7，本發明葉片裝置的一個第二實施例，與該第一實施例的不同之處在於：該等開闔單元22的結構。6 and 7 , a second embodiment of the blade device of the present invention is different from the first embodiment in the structure of the opening units 22 .

每一開闔單元22具有一跨接固定在兩相鄰第一柵桿211間的樞軸221、兩片樞接於該樞軸221並背向該運轉方向T往外延伸的開闔葉片222，及兩個分別位於該樞軸221兩端的引導框25。每一引導框25是由其中一第二柵桿212，朝反向於該運轉方向T弧彎並沿該第一柵桿211的延伸方向延伸至相鄰的第二柵桿212，並具有兩段分別與對應的該等第二柵桿212連接的引導段251，及一個自其中一個引導段251延伸至另一個引導段251且外徑較該等引導段251大的限位段252。且每一開闔單元22的該等引導框25的該等限位段252中，靠近該轉軸1(圖未示)的該限位段252的延伸長度比遠離該轉軸1的該限位段252的延伸長度長。Each opening unit 22 has a pivot 221 fixedly connected between two adjacent first fence rods 211 , two opening blades 222 pivotally connected to the pivot 221 and extending outwardly in the opposite direction of the rotation direction T, and two guide frames 25 respectively located at two ends of the pivot 221 . Each guide frame 25 is formed by one of the second fence rods 212, arc-bent in the opposite direction to the running direction T and extending along the extension direction of the first fence rod 211 to the adjacent second fence rod 212, and has two guide sections 251 respectively connected to the corresponding second fence rods 212, and a limiting section 252 extending from one of the guide sections 251 to the other guide section 251 and having an outer diameter larger than the guide sections 251. Among the limiting sections 252 of the guide frames 25 of each opening unit 22, the extending length of the limiting section 252 close to the rotating shaft 1 (not shown) is longer than the extending length of the limiting section 252 far from the rotating shaft 1.

每一開闔葉片222具有一其中一側樞接於各自的該樞軸221上的擋風片組224、兩個分別安裝於該擋風片組224相反於樞接於該樞軸221的一側並可移動地分別安裝於該等引導框25的活動環228，及一連接該擋風片組224除了連接樞軸221的一側以外的另外三側的邊條軟繩229。每一活動環228的內徑小於該限位段252的外徑，而被限位於對應的限位段252與對應的該第二柵桿212間沿各自的該引導段251移動。該等邊條軟繩229相較於該等擋風片組224具有較大的厚度，用於加強該等擋風片組224的平面結構。Each opening blade 222 has a windshield set 224 with one side pivoted to the respective pivot 221, two movable rings 228 respectively mounted on the side of the windshield set 224 opposite to the pivot 221 and movably mounted on the guide frames 25, and a side strip soft rope 229 connecting the other three sides of the windshield set 224 except the side connected to the pivot 221. The inner diameter of each movable ring 228 is smaller than the outer diameter of the limiting section 252, and is limited to move along the respective guide section 251 between the corresponding limiting section 252 and the corresponding second fence rod 212. The side strip soft ropes 229 have a greater thickness than the wind shielding plate assemblies 224 and are used to strengthen the planar structure of the wind shielding plate assemblies 224.

每一開闔葉片222是在對應的該第二柵桿212與對應的該等限位段252間，沿對應的該等引導段251移動，使每一開闔單元22可在該擋風狀態(參閱圖6)與該透風狀態(參閱圖7)切換。且在該透風狀態時，該等開闔葉片222相互靠近，但受限於該等限位段252而無法完全貼靠，且由於該等限位段252的延伸長度不同，使得該等開闔葉片222在該透風狀態時，構成一個離該轉軸1越遠越窄的開口26。當處於該透風狀態的該等開闔葉片222轉動至順風向的位置時，該風力F可穿過該開口26使該開闔單元22切換至該擋風狀態。且由於越靠近該轉軸1的風力相對較弱，因此該開口26越靠近該轉軸1的位置開啟範圍設計的越大，越能收集更多較弱的風力F從該開口26進入，使該等開闔葉片222沿該等引導框25移動得更為順暢。Each opening blade 222 moves along the corresponding guide sections 251 between the corresponding second fence rod 212 and the corresponding limiting sections 252, so that each opening unit 22 can switch between the wind blocking state (see FIG. 6) and the wind passing state (see FIG. 7). In the wind passing state, the opening blades 222 are close to each other, but cannot be completely close to each other due to the limitation of the limiting sections 252. Since the extension lengths of the limiting sections 252 are different, the opening blades 222 form an opening 26 that becomes narrower and narrower as it is farther from the rotation axis 1 in the wind passing state. When the opening blades 222 in the ventilation state rotate to a position in the wind direction, the wind force F can pass through the opening 26 to switch the opening unit 22 to the wind blocking state. Since the wind force closer to the rotation axis 1 is relatively weak, the opening range of the opening 26 is designed to be larger as it is closer to the rotation axis 1, so that more weak wind force F can be collected to enter from the opening 26, so that the opening blades 222 can move more smoothly along the guide frames 25.

要特別說明的是，每一開闔葉片222並不局限於利用該等活動環228設置於該等引導框25上，也可以直接在該開闔葉片222上設立兩個供該等引導框25的該等引導段251穿設的孔，一樣可以產生使該開闔葉片222沿該等引導框25移動的功能。It should be particularly noted that each opening blade 222 is not limited to being set on the guide frames 25 using the movable rings 228, but two holes for the guide sections 251 of the guide frames 25 to pass through can also be directly set on the opening blade 222, which can also produce the function of moving the opening blade 222 along the guide frames 25.

另外補充說明的是，在實施上，每一開闔單元22的該等開闔葉片222可以是兩擋風片組224分別樞接於該樞軸221上，也可以是以一擋風片組224，利用該擋風片組224的中間部與該樞軸221固定，使該擋風片組224中間部外的左右兩側邊部可相對該樞軸221樞擺，一樣可以達到使該開闔單元22可在該擋風狀態與該透風狀態間切換。It is further explained that, in practice, the opening blades 222 of each opening unit 22 can be two air-blocking plate groups 224 respectively pivoted on the pivot 221, or one air-blocking plate group 224 can be used, and the middle part of the air-blocking plate group 224 is fixed to the pivot 221, so that the left and right side edges outside the middle part of the air-blocking plate group 224 can be pivoted relative to the pivot 221, so that the opening unit 22 can be switched between the air-blocking state and the ventilation state.

綜上所述，本發明葉片裝置的功效在於：當該葉片模組2轉動至受到所述風力F作用而可以朝該運轉方向T旋轉的位置時，該等開闔單元22會切換至該擋風狀態而有效地擷取所述風力F，而使得整個葉片裝置旋轉，當轉動至受到所述風力F影響而會產生朝相反於該運轉方向T的作用力的位置時，該等開闔單元22會切換至該透風狀態而減少所述風力F的影響，增進該葉片裝置受所述風力F驅轉的效率，因此，確實能達到本發明的目的。In summary, the effect of the blade device of the present invention is that: when the blade module 2 rotates to the position where it can rotate in the running direction T due to the action of the wind force F, the opening units 22 will switch to the wind blocking state and effectively capture the wind force F, so that the entire blade device rotates. When it rotates to the position where it is affected by the wind force F and generates a force opposite to the running direction T, the opening units 22 will switch to the ventilation state to reduce the influence of the wind force F, thereby improving the efficiency of the blade device being driven by the wind force F. Therefore, the purpose of the present invention can be achieved.
