Abstract

Provided is a blade device, which can be driven by wind to rotate in an operation direction, and includes a shaft rod and a plurality of blade units. The blade units are installed on the shaft rod and are angularly spaced apart from each other. Each blade unit includes a main blade radially and outwardly extending in an arc bending manner from the shaft rod and having an arc concave surface facing away from the operation direction, and a first wind fixing sheet connected to the main blade. The first wind fixing sheet and the main blade jointly define a first wind collecting groove with an opening facing away from the operation direction. Due to the restriction of the first wind fixing sheet, the wind power will not move along the arc-bent main blade toward the shaft rod to reduce the torque generated by the wind power on the blade units, so as to improve the effectiveness of the blade device in collecting the wind power.

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, in particular to a blade device 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 power generation method that uses natural wind to drive mechanical components to rotate and convert rotational kinetic energy into electrical energy. Compared with the use of coal, petroleum and other thermal power generation, it causes less pollution to the environment. In addition to the amount of wind at the installation location, the efficiency of wind power generation is affected by how to effectively guide and collect the wind so that the blades can be driven by the wind to rotate. This problem has been a problem for 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。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 8. Its structure mainly includes a horizontally extending shaft 91 and several blades 92 extending radially outward from the shaft 91. The downwind blade 92 located above the rotating shaft 91 can drive the rotating shaft 91 to rotate in a rotating direction 93 along the wind force 8, but the upwind blade 92 located below the rotating shaft 91 receives the wind force 8 in the same direction. The torque in the opposite direction is generated to the rotating shaft 91, which reduces the efficiency of the rotating shaft 91. Moreover, although the curved blade 92 is designed to concentrate the wind force 8 in the wind blade device 9, the wind flowing along the curved blade 92 to the rotating shaft 91 does not effectively act on the blade 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 purpose of the present invention is to provide a blade device that can overcome 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 blade device of the present invention can be driven by wind to rotate in a direction of rotation, and includes a shaft and a plurality of blade units. The blade units are installed on the shaft and angularly spaced from each other. Each blade unit includes a main blade extending from the shaft radially to the outer arc and its arc concave surface facing away from the direction of rotation, and a first wind fixing piece connected to the main blade, the first wind fixing piece and The main blades jointly define a first air collecting groove 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 that the first wind-fixing pieces block the wind from moving along the arc-shaped main blades to the shaft, so that the wind near the extension ends of the blade units can be more complete The effect of the on the blade units, thereby improving the efficiency of collecting the wind.

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 represented by the same numbers.

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 Figures 2 and 3, a first embodiment of the blade device of the present invention can be rotated by the wind force F in an operating direction T. As shown in Figure 2, the wind force F is from right to left, and the operating direction T is reverse. Rotate in the clockwise direction. The blade device includes a shaft 1, three blade units 2 mounted on the shaft 1, and a plurality of blade units 2 connected to the shaft 1 and arranged at intervals along the axial direction of the shaft 1. Ring type 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的弧凹面向外並向該軸桿1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 installed on the shaft 1 and are equally angularly spaced from each other. Each blade unit 2 includes a main blade 21 that extends radially outward from the shaft 1 and has a concave arc facing away from the direction of rotation T. A first wind-fixing piece 22 connected to the main blade 21, several swing blades 23 swayably suspended on the main blade 21, and several counterweights 24 respectively disposed on the swing blades 23. The main blade 21 has a plurality of grid rods 211 arranged in a crisscross pattern, and a set of windshield fins 212 installed on the grid rods 211 at the end of its extension and is not permeable to wind. The first wind-fixing piece 22 extends outward from the arc concave surface of the main blade 21 to the shaft 1, and together with the wind-shielding piece group 212 of the main blade 21 defines an opening facing away from the direction of rotation T's first set of wind trough 221. The grid rods 211 between the connection of the first wind fixing piece 22 and the shaft 1 are not provided with wind-shielding cloth pieces, so the grid rods 211 located 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 on the horizontally extending grid rods 211 and correspond to the ventilation spaces 210 respectively. Each swing blade 23 has a connecting end 231 swingably connected to the grid rod 211, and a The swing end 232 away from the connecting end 231. The counterweights 24 are respectively disposed on the swing ends 232 of the swing blades 23. Each swing blade 23 is made of a flexible sheet made of canvas or other materials, such as graphene or other polymer materials, so that it can lean against the grid rods 211 to block the respective ventilation spaces 210 The closed position of, and an open position swinging away from the grid rods 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 bracket 3 is connected to the grid rods 211 extending radially outward from the shaft 1, so that the swinging blades 23 adjacent to the ring-shaped brackets 3 cannot lean against the corresponding ones when they are originally in the closed position. Rather, the grid bars 211 leaned against the ring-shaped brackets 3 to form an inclined surface 29 extending from the outermost edge of the ring-shaped brackets 3 toward the grid bars 211. The inclined surface 29 formed by the oscillating blades 23 leaning against the ring-shaped brackets 3, the other oscillating blades 23 in the closed position, and the first wind fixing piece 22 jointly define a wind receiving groove 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, an erection device (not shown) can be pivotally connected to the shaft 1 and used for erection. Taking the blade unit 2 located above the shaft 1 as an example, the blade unit 2 located above the shaft 1 is at a position where the wind force F is downwind with respect to the operating direction T, and the first fixed The wind blade 22 blocks the wind F far away from the shaft 1 and does not move downward from the extension end of the main blade 21 toward the shaft 1, so that the upper wind F is concentrated on the first wind collecting groove 221. The swinging blades 23 are blown by the wind force F and abut against the grid rods 211, and are in the closed position covering the ventilation spaces 210, so that the swinging blades 23 and the main blade 21 cooperate with each other to construct An airtight surface, and the swing blades 23 closest to the shaft 1 abut against the ring-shaped brackets 3 and form the inclined surface 29. The wind force F close to the shaft 1 is subjected to the The inclined surface 29 guides the upward movement and concentrates on the wind receiving groove 291 so that the wind force F can generate a relatively large rotational torque for the blade unit 2.

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 below the shaft 1 is at a position where the wind force F is upwind to the direction of rotation T, and the corresponding swing blades 23 receive the corresponding counterweights 24 and Move to the open position under the influence of the wind F, so that the ventilation spaces 210 will not be covered by the swing blades 23 but can be permeable, thereby reducing the torsion force opposite to the operating direction T, thereby increasing the blade device to collect wind F 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的弧凹面向外長向延伸，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 particularly noted that the shape of the first wind fixing pieces 22 is not limited to the curved shape. In terms of implementation, in other variations of the first embodiment, each first wind fixing piece 22 may also be Since the arc concave surface of each main blade 21 extends outwardly, the purpose of blocking the movement of the wind force F toward the shaft 1 can also be achieved.

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 is different from the first embodiment in that each blade unit 2 further includes a second wind fixing sheet 25.

以圖4之該軸桿1上方的該葉片單元2為例進行說明，該葉片單元2之該第二固風片25與該第一固風片22是沿該主葉片21徑向往外突伸方間隔上下排列。該葉片單元2在該第一固風片22與該軸桿1間設置該等擺動葉片23，該第二固風片25是設置在以該軸桿1的徑向上下相鄰的兩排擺動葉片23間，且不影響該等擺動葉片23在該開啟位置與該關閉位置移動。當該等擺動葉片23在該關閉位置時，該第二固風片25、該第一固風片22，及位於兩者間的該等擺動葉片23共同界定一第二集風槽251。藉由該第二固風片25可使更大範圍的所述風力F不會順著弧彎的該主葉片21朝該軸桿1移動，並使其留在該第二集風槽251中，提升所述風力F對該葉片單元2產生的扭力。Taking the blade unit 2 above the shaft 1 of FIG. 4 as an example for description, the second wind fixing piece 25 and the first wind fixing piece 22 of the blade unit 2 protrude radially outward along the main blade 21 The square intervals are arranged up and down. The blade unit 2 is provided with the swinging blades 23 between the first air-fixing piece 22 and the shaft 1, and the second air-fixing piece 25 is arranged in two rows of swinging adjacent to each other in the radial direction of the shaft 1. Between the blades 23 and does not affect the movement of the swing blades 23 between the open position and the closed position. When the swinging blades 23 are in the closed position, the second air-fixing sheet 25, the first air-fixing sheet 22, and the swinging blades 23 located therebetween collectively define a second air collecting groove 251. With the second wind fixing piece 25, the wind force F in a larger range will not move along the arc-bent main blade 21 toward the shaft 1 and keep it in the second air collecting groove 251 , The torsion force generated by the wind force F on the blade unit 2 is increased.

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 particularly noted that the number of the second air-fixing fins 25 of each blade unit 2 is not limited to one. As the radially outward dimensions of the blade units 2 from the shaft 1 increase, the number A plurality of second wind fixing fins 25 are arranged at radial intervals to increase the torsion force generated by the wind force F on the blade units 2.

參閱圖5至8，本發明葉片裝置的一個第三實施例，與該第一實施例的不同之處在於：沒有該等環型支架，並還包含了數個套接固定在該軸桿1的固定單元4，及三個回收單元5，且該等葉片單元2是可脫離地安裝在該等固定單元4。Referring to Figures 5 to 8, a third embodiment of the blade device of the present invention is different from the first embodiment in that there are no such ring-shaped brackets, and it also includes a plurality of sleeves fixed on the shaft 1 The fixed unit 4, and three recovery units 5, and the blade units 2 are detachably installed in the fixed units 4.

該等固定單元4是沿該軸桿1軸向間隔排列。每一固定單元4具有一個間隔圍繞該軸桿1的環壁41、三個連接該環壁41與該軸桿1並繞該軸桿1間隔排列的連接壁42，及三組分別安裝於該等連接壁42上且具有彈性的彈性件組43。每一連接壁4具有兩個同體相連並呈V字型的側壁部421，每一側壁部421具有一個面向另一側壁部421的壁面422，該等壁面422與該環壁41共同界定一個卡槽40。每一卡槽40具有一個鄰近該軸桿1的固定區401，及一個與該固定區401相通的活動區402。The fixing units 4 are arranged at intervals along the axis of the shaft 1. Each fixing unit 4 has a ring wall 41 that surrounds the shaft 1 at intervals, three connecting walls 42 that connect the ring wall 41 and the shaft 1 and are arranged at intervals around the shaft 1, and three groups are respectively mounted on the An elastic element group 43 that is connected to the wall 42 and has elasticity. Each connecting wall 4 has two V-shaped side wall portions 421 connected in the same body. Each side wall portion 421 has a wall surface 422 facing the other side wall portion 421. The wall surfaces 422 and the ring wall 41 jointly define a Card slot 40. Each slot 40 has a fixed area 401 adjacent to the shaft 1 and a movable area 402 communicating with the fixed area 401.

每一彈性件組43是固定於各自的連接壁42且部分外露於該等固定區401內，在本第三實施例中，每一彈性件組43包括兩個彈性鋼條431，每一彈性鋼條431具有一穿設於對應的該側壁部421的固定段432、一位於該卡槽40內的限位段433，及兩個連接該固定段432與該限位段433的兩相反端的連接段434。Each elastic element group 43 is fixed to the respective connecting wall 42 and partially exposed in the fixing areas 401. In the third embodiment, each elastic element group 43 includes two elastic steel bars 431, each elastic The steel bar 431 has a fixing section 432 penetrating the corresponding side wall portion 421, a limiting section 433 located in the slot 40, and two opposite ends of the fixing section 432 and the limiting section 433. Connect section 434.

每一葉片單元2還包括一設置於該主葉片21並與該等固定單元4嵌卡固定的嵌卡件26，該嵌卡件26是沿著該軸桿1的軸向長向延伸，並跨接固定在該等柵桿211靠近該軸桿1的一端，且其橫切面概呈尖端朝向該軸桿1的三角形。Each blade unit 2 further includes an insert piece 26 which is arranged on the main blade 21 and is inserted and fixed to the fixing units 4, and the insert piece 26 extends along the axial length of the shaft 1, and It is bridged and fixed at one end of the grid rods 211 close to the shaft 1, and the cross section of the grid rods 211 is almost triangular with the tip facing the shaft 1.

每一嵌卡件26可相對於該軸桿1在一驅轉位置(參閱圖8)與一脫開位置(參閱圖9)間移動，在該驅轉位置時，該嵌卡件26被對應之該彈性件組43的該等限位段433限位在對應的該固定區401內，並穩固抵靠在該等壁面422使對應之葉片單元2受風力F驅動時，可傳動該等固定單元4帶動該軸桿1旋轉；在該脫開位置時，該嵌卡件26從該固定區401移動至該活動區402，該活動區402的空間足夠讓該嵌卡件26可自由旋轉，進而使該葉片單元2能相對於該軸桿1擺動。Each inserting member 26 can move between a driving position (refer to FIG. 8) and a disengaging position (refer to FIG. 9) relative to the shaft 1. In the driving position, the inserting member 26 is corresponding The limiting sections 433 of the elastic element group 43 are limited in the corresponding fixed area 401, and firmly abut against the wall surfaces 422 so that the corresponding blade unit 2 can be driven by the wind force F. The unit 4 drives the shaft 1 to rotate; in the disengaged position, the insert 26 moves from the fixed area 401 to the movable area 402, and the space in the movable area 402 is sufficient for the insert 26 to rotate freely, In turn, the blade 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 recovery units 5 are located between the two adjacent 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 pull cord 52 wound around the recovery rod 51. Both ends of the pull cord 52 are respectively connected to the recovery rod 51 and the corresponding embedded rod. 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 elastic element groups 43 fix the inserting elements 26 at the driving position 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 wind F. When the 42 are driven by the wind, the inserts 26 will be pulled by the main blades 21 and squeeze the limiting sections 433. When the wind force F on the blade unit 2 on the windward side is too large When it is large, the inserting member 26 will force the corresponding elastic member group 43 to elastically deform, break free from the limit of the limit section 433, and move into the movable area 402 to change to the disengaged position. Each inserting member 26 pulls the corresponding pull cord 52 to drive the corresponding recovery rod 51 to rotate and release part of the pull cord originally wound on the recovery rod 51, so that the blade units 2 can swing backward in the wind direction , To reduce the impact of strong wind on the blade units 2.

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。To return an insert 26 changed to the disengaged position 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 rolls back the corresponding pull cord 52, thereby forcing the inserting member 26 to elastically stretch the elastic steel bars 431 corresponding to 43 to deform, and pull it from the movable area 402 to the fixed area 401, and The elastic element group 43 is again restricted to the fixed area 401 and returns to the driving position. Then the motor device is disengaged from the recovery rod 51 and connected to another recovery rod 51, and the above-mentioned actions are repeated to return the inserting members 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 particularly noted that each inserting member 26 is not limited to extending along the axial length of the shaft 1 to form a long rod shape, and can also be divided into several sections that are only engaged with the fixing unit 4 respectively.
