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 invention relates to a blade device, in particular to a blade device driven by wind to operate.

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 power generation method that uses natural wind to drive the rotation of mechanical components and converts the rotational kinetic energy into electrical energy. Compared with thermal power generation such as coal and oil, it causes less pollution to the environment. As for the efficiency of wind power generation, apart from the magnitude of the wind force at the installation location, how to effectively guide and collect the wind force so that the blades are driven by the wind to rotate is a problem that the industry has been improving.

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。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，降低該轉軸91旋轉的效率。且弧彎狀的葉片92設計雖然可以將所述風力8集中在該風力葉片裝置9內， 但順著弧彎狀的該葉片92而向轉軸91流動的風力沒有有效地作用在該葉片92上，進而降低風力收集使用的效率。 Referring to FIG. 1 , an existing wind blade device 9 can be driven by wind force 8 , and its structure mainly includes a horizontally extending shaft 91 and several blades 92 extending radially outward from the shaft 91 . The blades 92 in the downwind direction above the rotating shaft 91 can drive the rotating shaft 91 to rotate in a rotation direction 93 along the wind force 8, but the blades 92 in the upwind direction below the rotating shaft 91 are subjected to the wind force 8 in the same direction. Torsion in the opposite direction will be generated on the rotating shaft 91 , reducing the rotation efficiency of the rotating shaft 91 . And although the curved blade 92 design can concentrate the wind force 8 in the wind blade device 9, However, the wind force flowing along the arc-shaped blades 92 toward the rotating shaft 91 does not effectively act on the blades 92 , thereby reducing the efficiency of wind collection and use.

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 vane arrangement which overcomes at least one of the disadvantages of the prior art.

於是，本發明葉片裝置，可受風力驅動朝一運轉方向轉動，並包含一軸桿，及數個葉片單元。該等葉片單元安裝於該軸桿且彼此角度間隔。每一葉片單元包括一由該軸桿徑向朝外弧彎延伸且其弧凹面背向該運轉方向的主葉片，及一連接該主葉片的第一固風片，該第一固風片與該主葉片共同界定一開口背向該運轉方向的第一集風槽。 Therefore, the vane device of the present invention can be driven by wind to rotate in a running direction, and includes a shaft and several vane units. The blade units are mounted on the shaft and are angularly spaced from each other. Each blade unit includes a main blade that extends radially outward from the shaft and its concave surface faces away from the running direction, and a first wind-fixing piece connected to the main blade. The first wind-fixing piece is connected to the main blade. The main blades jointly define a first air collecting slot with an opening facing away from the running direction.

本發明的功效在於：藉由該等第一固風片阻擋所述風力順著弧彎狀的該等主葉片往該軸桿移動，使靠近該等葉片單元延伸末端的所述風力能更完整的作用在該等葉片單元上，進而提升收集所述風力的效率。 The effect of the present invention is: the first wind-fixing pieces block the wind force from moving along the arc-shaped main blades to the shaft, so that the wind force near the extension ends of the blade units can be more complete acts on the blade units, thereby improving the efficiency of collecting the wind force.

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 in the following description, similar elements are denoted by the same numerals.

參閱圖2、3，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2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軸桿1、三個安裝於該軸桿1上的葉片單元2，及數個連接該等葉片單元2並環繞該軸桿1且沿該軸桿1的軸向間隔排列的環型支架3。 Referring to Fig. 2, 3, a first embodiment of blade device of the present invention, can accept The wind force F rotates in a running direction T. As shown in FIG. 2 , the wind force F is from right to left, and the running direction T is counterclockwise. The blade device includes a shaft 1, three blade units 2 mounted on the shaft 1, and several blade units 2 connected to the shaft 1 and arranged at intervals along the axial direction of the shaft 1. Ring bracket 3.

該等葉片單元2安裝於該軸桿1且彼此等角度間隔，每一葉片單元2包括一個自該軸桿1徑向向外弧彎延伸且其弧凹面背向該運轉方向T的主葉片21、一連接該主葉片21的第一固風片22、數個可擺動地垂掛設置於該主葉片21的擺動葉片23，及數個分別設置於該等擺動葉片23的配重件24。該主葉片21具有數個縱橫交錯設置的柵桿211，及一組安裝於其延伸末段的該等柵桿211上且不透風的擋風片組212。該第一固風片22是由該主葉片21的弧凹面背向該運轉方向T且其弧凹面徑向朝內地弧彎延伸，並與該主葉片21的該擋風片組212共同界定一開口背向該運轉方向T的第一集風槽221。該第一固風片22的連接處到該軸桿1之間的該等柵桿211上沒有設置可擋風的布片，所以位在此區間的該等柵桿211共同界定出數個縱橫間隔排列的透風空間210。 The blade units 2 are mounted on the shaft 1 and are equiangularly spaced from each other. Each blade unit 2 includes a main blade 21 that extends radially outward from the shaft 1 and whose arc concave surface faces away from the running direction T. , a first wind-fixing piece 22 connected to the main blade 21 , several swing blades 23 that are swingably suspended from the main blade 21 , and several counterweights 24 that are respectively arranged on the swing blades 23 . The main blade 21 has several grid rods 211 arranged in a criss-cross pattern, and a set of airtight windshield blades 212 installed on the grid rods 211 at the end of its extension. The first wind-fixing piece 22 is formed by the arc concave surface of the main blade 21 facing away from the running direction T and its arc concave surface extends radially inwardly, and defines together with the windshield piece group 212 of the main blade 21 The opening of the first air collecting groove 221 faces away from the running direction T. There is no wind-shielding fabric on the grid bars 211 between the connection of the first wind-fixing piece 22 and the shaft 1, so the grid bars 211 in this section jointly define several vertical and horizontal Ventilation spaces 210 arranged at intervals.

該等擺動葉片23可擺動地垂掛設置於橫向延伸的該等柵桿211且分別對應該等透風空間210，每一擺動葉片23具有一可擺動地連接該柵桿211的連接端231，以及一遠離該連接端231的擺動端232。該等配重件24分別設置於該等擺動葉片23之該等擺動端 232。每一擺動葉片23是以例如帆布或其他材質，例如以石墨烯或其他高分子材料製成的可撓曲薄片，因此可在一擺靠於該等柵桿211而遮擋各別之透風空間210的關閉位置，以及一擺離該等柵桿211而使各別之透風空間210可透風的開啟位置間移動。 The swing blades 23 are swingably hung from the horizontally extending grid bars 211 and respectively correspond to the ventilation spaces 210. Each swing blade 23 has a connecting end 231 swingably connected to the grid bars 211, and a The swing end 232 away from the connecting end 231 . The counterweights 24 are respectively arranged on the swing ends of the swing blades 23 232. Each swing vane 23 is a flexible sheet made of canvas or other materials, such as graphene or other polymer materials, so it can shield the respective ventilation spaces 210 when swinging against the grilles 211 The closed position, and an open position that swings away from the grid bars 211 so that the respective ventilation spaces 210 can be ventilated.

每一環型支架3是連接自該軸桿1徑向往外延伸的該等柵桿211，使鄰近該等環型支架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等柵桿211，而是靠抵於該等環型支架3上，形成一個由該等環型支架3的最外緣向該等柵桿211延伸的斜面29。靠抵在該等環型支架3上的該等擺動葉片23所構成之所述斜面29、其它在該關閉位置的該等擺動葉片23，及該第一固風片22共同界定一個受風槽291。 Each ring-shaped support 3 is connected to the grid rods 211 extending radially outward from the shaft rod 1, so that the swing blades 23 adjacent to the ring-shaped support 3 cannot abut against the corresponding when they are originally in the closed position. The grid rods 211 are leaned against the ring-shaped brackets 3 to form a slope 29 extending from the outermost edge of the ring-shaped brackets 3 to the grid rods 211 . The slope 29 formed by the swinging blades 23 leaning against the ring brackets 3, the other swinging blades 23 in the closed position, and the first wind-fixing piece 22 jointly define a wind receiving slot 291.

該第一實施例在使用時，可藉由一架設裝置(圖未示)樞接於該軸桿1並架高使用。以位於該軸桿1上方之該葉片單元2為例進行作動說明，位於該軸桿1上方的葉片單元2處於該風力F對該運轉方向T而言是順風向的位置，利用該第一固風片22阻擋離該軸桿1較遠的風力F不會從該主葉片21的延伸末端向下往該軸桿1移動，使上方的風力F集中於該第一集風槽221。該等擺動葉片23受到所述風力F吹動而靠抵於該等柵桿211，而處在遮蓋該等透風空間210的該關閉位置，使該等擺動葉片23與該主葉片21相互配合建構一個不透風的面，且最靠近該軸桿1的該等擺動葉片23是靠抵於 該等環型支架3上並形成所述斜面29，靠近該軸桿1的所述風力F受到所述斜面29導引朝上方移動並集中在該受風槽291，使所述風力F可對於該葉片單元2產生較大的旋轉扭力。 When the first embodiment is in use, it can be pivotally connected to the shaft 1 by an erection device (not shown in the figure) and can be elevated for use. Taking the blade unit 2 above the shaft 1 as an example for operation description, the blade unit 2 above the shaft 1 is in a position where the wind force F is downwind to the running direction T. The wind vane 22 prevents the wind force F far from the shaft 1 from moving downward from the extension end of the main blade 21 to the shaft 1 , so that the upper wind force F concentrates on the first wind collecting groove 221 . The swing blades 23 are blown by the wind force F and lean against the grid rods 211, and are in the closed position covering the ventilation spaces 210, so that the swing blades 23 and the main blade 21 are constructed in cooperation with each other. an airtight surface, and the swing blades 23 closest to the shaft 1 are against the The slope 29 is formed on the ring-shaped brackets 3, and the wind force F close to the shaft 1 is guided by the slope 29 to move upward and concentrate on the wind receiving slot 291, so that the wind force F can be The blade unit 2 generates relatively large rotational torque.

於此同時，位於該軸桿1下方的該葉片單元2處於該風力F對該運轉方向T而言是逆風向的位置，對應的該等擺動葉片23受到對應的該等配重件24以及所述風力F的影響而移動至該開啟位置，令該等透風空間210不會被該等擺動葉片23遮蓋而可透風，從而減少相反於該運轉方向T的扭力，進而提高該葉片裝置收集風力F的效率。 At the same time, the blade unit 2 located under the shaft 1 is in a position where the wind force F is against the wind direction T, and the corresponding swing blades 23 are supported by the corresponding counterweights 24 and the corresponding Move to the open position under the influence of the above-mentioned wind force F, so that the ventilation spaces 210 will not be covered by the swing blades 23 and can be ventilated, thereby reducing the torsion force opposite to the running direction T, thereby increasing the wind force F collected by the blade device s efficiency.

要特別說明的是，該等第一固風片22的形狀並不局限於弧彎狀，實施上，在該第一實施例的其他變化例中，每一第一固風片22也可以是由各別之主葉片21的弧凹面背向該運轉方向T長向延伸，一樣可以達到阻擋所述風力F朝該軸桿1移動的目的。 It should be noted that the shape of the first wind-fixing pieces 22 is not limited to a curved shape. In practice, in other variations of the first embodiment, each first wind-fixing piece 22 can also be The arc-concave surfaces of the main blades 21 extend longitudinally away from the running direction T, which can also achieve the purpose of blocking the wind force F from moving toward the shaft 1 .

參閱圖4，本發明的一個第二實施例，與該第一實施例的不同之處在於：每一葉片單元2還包括一個第二固風片25。 Referring to FIG. 4 , a second embodiment of the present invention differs from the first embodiment in that each blade unit 2 further includes a second wind-fixing piece 25 .

When the swing blades 23 are in the closed position, the second wind-fixing piece 25 , the first wind-fixing piece 22 , and the swing blades 23 between them jointly define a second wind-collecting slot 251 . By means of the second wind-fixing piece 25, the wind force F in a larger range will not move towards the shaft 1 along the curved main blade 21, and make it stay in the second wind collecting groove 251 , to increase the torsion force generated by the wind force F on the blade unit 2 .

要特別說明的是，每一葉片單元2的該第二固風片25的數量並不局限於一個，隨著該等葉片單元2的自該軸桿1的徑向向外尺寸增加，可再徑向間隔設置多個第二固風片25以提升所述風力F對該等葉片單元2產生的扭力。 It should be noted that the number of the second wind-fixing fins 25 of each blade unit 2 is not limited to one, as the radially outward dimension of the blade units 2 from the shaft 1 increases, the A plurality of second wind-fixing fins 25 are radially spaced to increase the torsion force generated by the wind force F on the blade units 2 .

The unit 4 drives the shaft 1 to rotate; when in the disengaged position, the engaging member 26 moves from the fixed area 401 to the movable area 402, and the space of the movable area 402 is enough for the engaging member 26 to rotate freely. Furthermore, the vane unit 2 can swing relative to the shaft 1 .

該等回收單元5是位於相鄰的兩個該等連接壁42之間並 固定於該軸桿1上。每一回收單元5包括一可繞自身軸心轉動的回收桿51，及一條纏繞於該回收桿51的拉繩52，該拉繩52的兩端分別連接於該回收桿51以及對應的該嵌卡件26。 The recycling units 5 are located between the adjacent two connecting walls 42 and fixed on the shaft 1. Each recovery unit 5 includes a recovery rod 51 that can rotate around its own axis, and a stay rope 52 wound around the recovery rod 51. The two ends of the stay rope 52 are respectively connected to the recovery rod 51 and the corresponding embedded card 26.

配合參閱圖9，該第三實施例使用時，是以該等彈性件組43將該等嵌卡件26固定在該驅轉位置，使該等葉片單元2能受到所述風力F吹動，而帶動該等固定單元4連動該軸桿1轉動，達到收集風力F的目的。在該等42被風驅轉過程中，該等嵌卡件26會被該等主葉片21拉扯而擠壓該等限位段433，當位於迎風面之該葉片單元2所承受的風力F太大時，其嵌卡件26會迫使對應之彈性件組43彈性變形，而掙脫該限位段433的限位，並位移進入該活動區402，而變化至該脫開位置，此時。每一嵌卡件26拉動對應的該拉繩52而帶動對應的該回收桿51旋轉並釋放原先纏繞在該回收桿51上的部分拉繩，進而使該等葉片單元2可順著風向向後擺動，減少該等葉片單元2受到強風的影響。 With reference to FIG. 9 , when the third embodiment is used, the embedded parts 26 are fixed at the driving position by the elastic part groups 43, so that the blade units 2 can be blown by the wind force F, The fixed units 4 are driven to rotate the shaft 1 to achieve the purpose of collecting the wind force F. When these 42 are rotated by the wind, the inserting parts 26 will be pulled by the main blades 21 and squeeze the limiting sections 433. When it is large, the engaging member 26 will force the corresponding elastic member group 43 to elastically deform, break away from the limit of the limit section 433, and move into the movable area 402 to change to the disengaged position. Each engaging member 26 pulls the corresponding pull cord 52 to drive the corresponding recovery rod 51 to rotate and release the part of the pull cord originally wound on the recovery rod 51, so that the blade units 2 can swing backward along the wind direction , to reduce the impact of the blade units 2 from strong winds.

要將變化至該脫開位置的一個嵌卡件26回復至該驅轉位置時，可透過將一馬達裝置(圖未示)安裝連結於對應之該回收桿51，由該馬達裝置驅轉該回收桿51以捲回對應之該拉繩52，進而迫使該嵌卡件26將對應之43的該等彈性鋼條431彈性撐開變形，而從該活動區402拉至該固定區401，並再次被該彈性件組43限位於該固定區401而回復至該驅轉位置。接著將該馬達裝置脫開該回收 桿51並再與另一個該回收桿51連結，重複上述動作將該等嵌卡件26皆回復至該驅轉位置。 When an embedding part 26 changed to the disengaged position is returned to the driving position, a motor device (not shown) can be installed and connected to the corresponding recovery rod 51, and the motor device can drive the The recovery rod 51 is used to roll back the corresponding pull cord 52, and then force the embedded part 26 to elastically expand and deform the elastic steel strips 431 corresponding to the corresponding 43, and pull it from the movable area 402 to the fixed area 401, and Restricted by the elastic element set 43 in the fixed area 401 again, it returns to the driving rotation position. Then disengage the motor unit from the recovery The rod 51 is connected with another recovery rod 51 again, and the above-mentioned action is repeated to return the embedded parts 26 to the driving position.

要特別說明的是，每一嵌卡件26並不局限於沿該軸桿1的軸向長向延伸呈長桿狀，也可分成數個僅分別與該固定單元4嵌接的段落亦可達到將該葉片單元2可脫離地固定在該軸桿1的目的，且驅轉該回收單元5的方式並不局限於利用外接的馬達裝置，亦可將數個馬達裝置直接安裝於該葉片裝置上，驅動該等馬達裝置分別旋轉該等回收桿51，由於驅轉該回收單元5的方式很多且並非本發明葉片裝置的創作重點，故不再贅述。 It should be noted that each engaging member 26 is not limited to be long rod-shaped extending along the axial direction of the shaft 1, and can also be divided into several sections that only engage with the fixing unit 4 respectively. To achieve the purpose of detachably fixing the vane unit 2 to the shaft 1, and the way of driving the recovery unit 5 is not limited to using an external motor device, and several motor devices can also be directly installed on the vane device Above, drive the motor devices to rotate the recovery rods 51 respectively. Since there are many ways to drive the recovery unit 5 and it is not the focus of the blade device of the present invention, it will not be repeated here.

綜上所述，本發明葉片裝置的功效在於：利用該等第一固風片22，阻擋所述風力F順著弧彎狀的該等主葉片21往該軸桿1移動，且該等擺動葉片23可在所述風力F對該葉片單元2產生相反於該運轉方向T的反向力時移至該開啟位置，使所述風力F可穿過該葉片單元2進而減少反向力的影響，提升收集所述風力F的效率；該等固定單元4與該等嵌卡件26的設計可降低該等葉片單元2受到強風直接吹壞，因此，確實能達到本發明的目的。 To sum up, the effect of the blade device of the present invention is to use the first wind-fixing blades 22 to block the wind force F from moving toward the shaft 1 along the arc-shaped main blades 21, and the swing The blade 23 can move to the open position when the wind force F produces a reverse force on the blade unit 2 opposite to the running direction T, so that the wind force F can pass through the blade unit 2 to reduce the influence of the reverse force , improve the efficiency of collecting the wind force F; the design of the fixing units 4 and the inserting parts 26 can reduce the blade units 2 from being directly damaged by strong wind, therefore, the purpose of the present invention can indeed be achieved.
