The wind area and moment, and when the wind speed is high, are conducive to the centrifugal force generated by the counterweight element, thereby driving the pivot rod and fan blades to lift, pivot and fold, thereby reducing the wind area and moment, and can also respond through mechanical means. It automatically adjusts its wind receiving area and moment according to the wind force.
按，近年來地球暖化現象漸趨嚴重，世界各國分別提出節能減碳及環保策略等議題，進而研發替代能源及再生能源之應用，而現行較大規模之再生能源發電設備，主要係以風力發電為首選；然而，由於風速係屬無法控制之變因，而過大或過小之風速皆無法使風力發電機正常發電，且風力發電機於相異之風速下，其轉速及發電之效率亦不盡相同，故如何能有效利用風能發電，為現今風力發電主要研究探討之議題。According to reports, the phenomenon of global warming has become increasingly serious in recent years. Countries around the world have proposed issues such as energy conservation, carbon reduction and environmental protection strategies, and then developed the application of alternative energy and renewable energy. Currently, large-scale renewable energy power generation equipment is mainly based on wind power. Power generation is the first choice; however, since wind speed is an uncontrollable variable, wind turbines that are too large or too small cannot generate electricity normally, and wind turbines have different speeds and power generation efficiency at different wind speeds. They are all the same, so how to effectively utilize wind energy to generate electricity is the main topic of current wind power research and discussion.
由於風力發電機葉片之仰角、長度及導流面積，皆影響葉片之轉速，於相同風速下，葉片仰角越大，力矩及空氣阻力亦將增加，反之，葉片仰角越小，力矩及空氣阻力會越小；而垂直式之風力發電機，少有可因應風速而調整葉片傾角之配置，而有其設計者，通常機構較為繁雜，組裝不易，且成本較高；此外，在實際應用上多有受限，導致難以有效進行應用。Since the elevation angle, length and flow guide area of the wind turbine blades all affect the rotation speed of the blades, at the same wind speed, the greater the blade elevation angle, the torque and air resistance will also increase. On the contrary, the smaller the blade elevation angle, the torque and air resistance will increase. The smaller the wind turbine is; vertical wind turbines rarely have configurations that can adjust the blade inclination in response to wind speed, and those who do have such designs usually have complex mechanisms, difficult assembly, and high costs; in addition, there are many practical applications Limited, making it difficult to apply effectively.
有鑑於此，本創作人特地針對可因應風力大小而進行轉速控制之垂直式風力發電機加以研究及改良，期以一較佳創作改善上述問題，並在經過長期研發及不斷測試後，始有本創作之問世。In view of this, the author specially researched and improved the vertical wind turbine that can control the speed according to the wind strength, hoping to improve the above problems with a better creation.

是由上述說明及設置，顯見本創作主要具有下列數項優點及功效，茲逐一詳述如下：From the above description and settings, it is obvious that this creation mainly has the following advantages and effects, which are detailed below:
1.本創作透過樞接桿及配重元件之設置，藉以於初始狀態或風速較小之情形下，樞接桿將受配重元件之重量而令樞接桿可樞轉至水平位置，使扇葉遠離於轉軸而呈展開位置，藉可提升受風面積，並可增加對於轉軸傳動之力矩；並於風速較大時，因應轉軸及扇葉之轉動，而使配重元件產生離心力，而配重元件之離心力將使配重元件朝遠離轉軸之方向抬升，進而帶動樞接桿及扇葉抬升並朝轉軸之方向樞轉並收合，以降低扇葉之受風面積，並可減少對轉軸之力矩，使可於風速過高時，降低轉軸之轉速，以防發電機因轉速過高而損壞，藉以令本創作無需另設置相關主動式裝置，或剎車等相關減速、逆止之構件，即可機械式因應風速而自動調整受風面積及力矩，以提升風力發電之效率，且本創作整體之構造簡單，體積較小，且耐用性佳，故可大幅將低其製造及設置成本，使可有助於進行大範圍之廣範建置，以有助於提升風力發電之佈建，進而可達致節能環保之功效及目標者。1. In this invention, through the arrangement of the pivot rod and the counterweight element, in the initial state or under the condition of low wind speed, the pivot rod will be subject to the weight of the counterweight element so that the pivot rod can pivot to a horizontal position, allowing the fan to The blades are in an expanded position away from the rotating shaft, which can increase the wind receiving area and increase the torque transmitted to the rotating shaft; and when the wind speed is high, the counterweight element generates centrifugal force in response to the rotation of the rotating shaft and fan blades, and the counterweight element is The centrifugal force of the heavy component will lift the counterweight component in the direction away from the rotating axis, thereby driving the pivot rod and the fan blade to lift, pivot and fold in the direction of the rotating axis, thereby reducing the wind receiving area of the fan blade and reducing the opposition to the rotating axis.

本創作係一種可變式扇葉垂直風力發電機，其實施手段、特點及其功效，茲舉數種較佳可行實施例並配合圖式於下文進行詳細說明，俾供 鈞上深入瞭解並認同本創作。This invention is a variable-blade vertical wind turbine. Its implementation means, characteristics and functions are described in detail below with several preferred embodiments and drawings, so as to provide readers with an in-depth understanding and recognition. This creation.
首先，請參閱第1圖至第3圖所示，本創作係一種可變式扇葉垂直風力發電機，其包含：First of all, please refer to Figures 1 to 3. This invention is a variable blade vertical wind turbine, which includes:
一轉軸1，其主要係應用於垂直式風力發電之配置，故轉軸1係呈直立式設置，而該轉軸1係徑向樞設有至少一樞接桿2，用以令所述樞接桿2沿對應於該轉軸1之軸向方向樞轉者；而該轉軸1之配置，係於其一末端係對應連接於一發電裝置3，用以透過轉軸1之旋轉以直接或間接的傳動至發電裝置3，藉以進行其發電者；而其對於傳動於發電裝置3之方式及發電之作用機制，其係屬習知技術，故在此不予贅述；以及A rotating
至少一扇葉4，其係對應樞設於所述樞接桿2相對於該轉軸1之一端；且至少其一所述樞接桿2於遠離該轉軸1處之下端位置設有一配重元件21，且該配重元件21之重心位置係低於所述樞接桿2，用以令所述樞接桿2受該配重元件21之重量而令樞接桿2朝相對該轉軸1轉動，令對應之所述扇葉4呈一展開位置；並於所述扇葉4受力而帶動該轉軸1及所述樞接桿2轉動時，令所述配重元件21產生一離心力F而抬升，進而帶動所述樞接桿2及所述扇葉4朝該轉軸1之方向樞轉而呈一收合位置者。At least one
藉此，由於配重元件21之重心位置係低於所述樞接桿2，因此，於初始狀態下，或於風速較低之情形下，配置有配重元件21之樞接桿2將會受配重元件21之重量而朝向重力方向樞轉移動，此將令所述扇葉4受樞接桿2之樞轉而朝遠離轉軸1之方向移動而呈如第1圖及第3圖所示之展開位置，此時，由於扇葉4係遠離於轉軸1，故具有較大之受風面積，並具有較長之力臂長度，因此，可對於轉軸1產生較大之力矩，因此，當於風速較小之情形下，使風力可較易於推動扇葉4使轉軸1旋轉而令發電裝置3進行發電；而為令所述扇葉4呈該展開位置時，扇葉4與轉軸1間之距離最大化，故配將樞接桿2及轉軸1間之樞接方式配置為於展開位置時，所述樞接桿2與該轉軸1間係略呈垂直設置，故可知悉者，轉軸1及樞接桿2間係可透過限位元件（圖未繪示）之配置，使於展開位置之狀態下，樞接桿2可與水平面平行，而其配置係屬習知技術，故於此不予贅述之。Therefore, since the center of gravity of the
反之，如第4圖及第5圖所示者，當於風速較高之情形下，因應其作用於扇葉4之風力較大，故將使扇葉4透過樞接桿2帶動轉軸1產生之轉速增加，其亦將使配置於樞接桿2之配重元件21繞轉軸1旋轉之轉速增加，進而令配重元件21相對該轉軸1而產生離心力F，而由於原配重元件21係位於樞接桿2下端，且其重心係低於樞接桿2，故當其產生離心力F時，配重元件21將因應風速之增加而逐漸的朝遠離於轉軸1之方向抬升移動，此亦將帶動樞接桿2及扇葉4而逐漸抬升，並朝接近於轉軸1之方向樞轉移動，使扇葉4與轉軸1間之垂直距離縮小，進而可降低其可產生之力矩及本創作整體之受風面積，藉可防止轉軸1之轉速過高而致使發電裝置3有損壞之疑慮者；而可知悉者，配重元件21所產生離心力F之大小係受風力帶動轉軸1旋轉之轉速而定，故配重元件21抬升之角度，以及對應的扇葉4與轉軸1間之距離，將可因應風力之大小而有所差異，藉可於轉軸1之轉速在一定區間內，配重元件21可因應風速之大小而對應產生相應之離心力F，並可對應的抬升以控制扇葉4與轉軸1間之距離，藉以令本創作可於一定之風速區間內，可因應風速大小進行抬升角度之微調，以提升本創作對於風速之適應性，並據以達致較佳之發電效率者。On the contrary, as shown in Figures 4 and 5, when the wind speed is high, the wind force acting on the
其中，就轉軸1與樞接桿2間之樞轉連接配置而言，在一實施例中，轉軸1係透過其本身延伸或套接配置有至少一連接座11，而所述連接座11分別設有複數連接部件111，且所述樞接桿2係對應樞接於其一所述連接部件111，而為利於樞接桿2對於扇葉4可進行穩定之傳動及固設，故較佳者，如本實施例所示，轉軸1係透過設置有二連接座11，而相異連接座11於對應位置之連接部件111皆分別設置有一相互對應之樞接桿2，且對應之所述樞接桿2係分別連接於同一扇葉4，且其一之樞接桿2係設置有配重元件21，而較佳者，係於較低位置之樞接桿2配置配重元件21，藉以令本創作之整體重心位置較低，以提升其於運作時之穩定性；而為提升本創作之於轉動時之穩定性，故在本實施例中，係共設置有三組扇葉4，且所述扇葉4係於轉軸1旋轉平面呈120度間隔設置，惟其僅係舉例說明，並不以此作為限定。Among them, as for the pivotal connection arrangement between the rotating
而就連接部件111及樞接桿2間之樞接方式而言，其在一實施例中，其係可分別延伸設置有至少一相對應之樞接片，並且分別穿設有一樞接孔，藉以令連接部件111及樞接桿2間透過其分別樞接片之樞接孔相互對合後，可透過一插銷（圖未繪示）以對應穿固於樞接孔以完成其樞接；而樞接桿2與扇葉4間，亦可透過相同之樞接片、樞接孔及插銷的方式進行樞接，惟其皆僅係舉例說明，並不以此作為限定。As for the pivotal connection between the connecting
而就配重元件21之設置而言，其在一實施例中，係可呈長條狀設置，藉以盡可能地降低其重心位置，使較易於受旋轉而抬升；而配重元件21配重元件21與所述樞接桿2間，在一實施例中，其係呈一體成形設置，並令其整體略T型設置，藉以利於進行其成型及模組化配置；且較佳者，配重元件21亦可更近一步於其底端配置至少一配重塊（圖未繪示），使配重元件21可更易於受旋轉時產生較大之離心力F而據以抬升，並帶動樞接桿2及扇葉4抬升而朝接近於轉軸1之方向樞轉。As for the arrangement of the
而在一較佳之實施例中，為更進一步提升本創作於轉動發電時之穩定性，故係可更包含至少一固定式葉片5，其較佳者係可設置對應於扇葉4之數量，且分別與扇葉4間隔環狀排列設置，使可維持其於水平方向之平衡；而固定式葉片5係設有至少一對應固接於至少其一所述連接部件111之組接元件，且所述固定式葉片5係藉由所述組接元件以對應固設於該轉軸1之徑向方向，藉以無論風速大小，固定式葉片5皆與轉軸1之距離相等，而不因應風速而改變，使可有助於維持於轉動時之穩定性者。In a preferred embodiment, in order to further improve the stability of the invention when rotating to generate electricity, it can further include at least one
