Description
本發明與風力發電機的風車有關，更詳而言之，該風車具有可將複數扇葉收合至與葉轂之中心軸平行或展開至與中心軸呈垂直相交的技術特徵。The present invention relates to windmills for wind turbines, and more particularly, the windmill has the technical feature of folding a plurality of blades to parallel or unfolding to a central axis of the hub to perpendicularly intersect the central axis.
風力發電機之基本構造大致包括一塔架，一組裝於塔架頂端的發電機體，一組裝於該發電機體之馬達心軸的葉轂，以及鎖付固定於該葉轂的複數扇葉。The basic structure of a wind power generator generally comprises a tower, a generator body assembled at the top of the tower, a hub assembled to the motor spindle of the generator body, and a plurality of blades fixed to the hub.
目前風力發電機的組立方式之一，係預先將葉轂組裝於馬達心軸，再將發電機體吊掛至豎立的塔架頂端鎖付固定，扇葉則是單支的被吊掛至與發電機體對應的高度，再鎖付於葉轂上。複數次的扇葉吊掛作業以及高空對位組裝扇葉之困難度，使風車的組裝時間延長，工程人員停駐於高空的時間增加，危險性提高。At present, one of the methods of assembling a wind turbine is to assemble the blade hub to the motor spindle in advance, and then suspend the generator body to the top of the erected tower for locking and fixing, and the fan blade is slinged to and generated by a single branch. The height corresponding to the body is then locked on the hub. The fan blade hanging operation and the difficulty of assembling the fan blade at high altitude make the assembly time of the windmill prolonged, and the time for the engineer to stay at the high altitude increases, and the danger is improved.
風力發電機的組立方式之二，係預先將扇葉與葉轂完成組裝，再利用吊車將扇葉與葉轂的組合體吊掛至與發電機體對應的高度進行鎖付作業。雖較上述方式減少了扇葉吊掛的次數，但是，展開的扇葉於吊掛過程中易受風吹而晃動，使得吊掛作業的困難度和危險性提高。The second way of assembling the wind turbine is to assemble the blade and the hub in advance, and then use the crane to hang the combination of the blade and the hub to the height corresponding to the generator body for locking operation. Although the number of fan blade suspensions is reduced as compared with the above manner, the unfolded blades are susceptible to wind and sway during the hanging process, which makes the difficulty and danger of the hanging operation improved.
本案之目的係在提供一種風力發電機之風車裝置，其具有簡化高空吊掛作業次數，縮短高空吊掛作業時間及減少高空對位鎖付扇葉之困難度以及增進吊掛作業安全性等功能。The purpose of this case is to provide a wind turbine generator device, which has the functions of simplifying the number of high-altitude hanging operations, shortening the working time of high-altitude hanging, reducing the difficulty of locking the blade at high altitude, and improving the safety of the hanging operation. .
本案之目的係在提供一種風力發電機之風車裝置，其係一可適用於升降塔台的風車裝置。The purpose of the present invention is to provide a wind turbine generator for a wind turbine, which is a windmill device that can be applied to an elevator tower.
一種風力發電機之風車裝置，包括：一葉轂；複數個固定於該葉轂的固定座；以及複數個分別以一根部組裝於該固定座中的扇葉；其中，每一扇葉具有平行於該葉轂之中心軸的一收合位置以及與該葉轂之中心軸呈垂直的一展開位置。A wind turbine device for a wind power generator, comprising: a hub; a plurality of fixing bases fixed to the hub; and a plurality of blades respectively assembled in the fixing seat by one portion; wherein each of the blades has a parallel A folded position of the central axis of the hub and a deployed position perpendicular to the central axis of the hub.
為便於說明本案於上述發明內容一欄中所表示的中心思想，茲以具體實施例表達。實施例中各種不同物件係按適於說明之比例、尺寸、變形量或位移量而描繪，而非按實際元件的比例予以繪製，合先敘明。且以下的說明中，類似的元件是以相同的編號來表示。如第一圖和第二圖，本案風車裝置包括一葉轂10，複數個鎖付於該葉轂10的固定座20，以及複數個分別以根部31組裝於該固定座20的扇葉30。For the convenience of the description, the central idea expressed in the column of the above summary of the present invention is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above. In the following description, like elements are denoted by the same reference numerals. As shown in the first and second figures, the windmill apparatus of the present invention includes a hub 10, a plurality of fixed seats 20 for the locks to be applied to the hub 10, and a plurality of blades 30 respectively assembled to the fixed bases 20 by the roots 31.
該固定座20具有一基板24，該基板24具有相對的一第一側壁21和一第二側壁22，一第三側壁23連接於該第一側壁21和該第二側壁22的一端；該第一側壁21和該第二側壁22於相對位置設有複數個孔洞211,221。該複數個固定座20係以螺絲將基板24鎖付於該葉轂10的正面11，該葉轂10的正面11具有用以接收該基板24的限位槽12，限位槽12之限位作用以及複數螺絲之鎖付固定，可確保該固定座20穩固定位於該葉轂10而無位移之虞。The mounting base 20 has a base plate 24 having a first side wall 21 and a second side wall 22, and a third side wall 23 is connected to one end of the first side wall 21 and the second side wall 22; A side wall 21 and the second side wall 22 are provided with a plurality of holes 211, 221 at opposite positions. The plurality of fixing bases 20 are screwed to the front surface 11 of the hub 10 by screws. The front surface 11 of the hub 10 has a limiting slot 12 for receiving the substrate 24, and the limiting slot 12 is limited. The action and the locking and fixing of the plurality of screws ensure that the fixing base 20 is stably fixed on the hub 10 without displacement.
該扇葉30具有一似矩形塊狀的根部31，該根部31具有複數個貫穿其二窄側的穿孔32。該根部31設於該第一側壁21和該第二側壁22之間，其兩側分別接觸該第一側壁21和該第二側壁22。該根部31的複數穿孔32和該第一和第二側壁21,22的複數孔洞211,221一一對應時可供複數個螺栓穿鎖，將扇葉30的根部31固定於該固定座20中。The blade 30 has a root portion 31 which is shaped like a rectangular block and has a plurality of perforations 32 extending through its narrow sides. The root portion 31 is disposed between the first sidewall 21 and the second sidewall 22, and has two sides contacting the first sidewall 21 and the second sidewall 22, respectively. When the plurality of through holes 32 of the root portion 31 and the plurality of holes 211, 221 of the first and second side walls 21, 22 are in one-to-one correspondence, a plurality of bolts can be locked to fix the root portion 31 of the blade 30 in the fixing base 20.
基於該第一側壁21和第二側壁22的複數孔洞211,221的排列方向是與該葉轂10的中心軸呈垂直，且該根部31的複數穿孔32的排列方向是與該扇葉30的中心軸平行，因此當扇葉30的複數穿孔32和該複數孔洞211,221一一對應並以複螺栓41,42,43(顯示於第六圖)鎖付時，該扇葉30在與該葉轂10的中心軸呈垂直相交的展開位置，其展開樣態如第五圖和第六圖所示。The arrangement direction of the plurality of holes 211, 221 based on the first side wall 21 and the second side wall 22 is perpendicular to the central axis of the hub 10, and the arrangement direction of the plurality of perforations 32 of the root portion 31 is the central axis of the blade 30. Parallel, such that when the plurality of perforations 32 of the blade 30 and the plurality of holes 211, 221 are in one-to-one correspondence and locked by the multiple bolts 41, 42, 43 (shown in Figure 6), the blade 30 is in contact with the hub 10. The central axis is in a vertically intersecting deployed position, and its unfolded state is as shown in the fifth and sixth figures.
將該固定座20靠近該葉轂10圓週位置的兩個螺栓41,42拆除，使該根部31僅以一個螺栓43鎖付於該固定座20中，此時，該扇葉30得以該螺栓43為圓心於該固定座20中以相對於該葉轂10之中心軸做0~90度的旋擺。特別是旋擺至0度時，該扇葉30在與該葉轂10的中心軸呈平行的收合位置，該固定座20的第三側壁23支托著該扇葉30之根部31，複數扇葉30收合如第三圖和第四圖所示。The two bolts 41, 42 of the fixing seat 20 near the circumferential position of the hub 10 are removed, so that the root portion 31 is locked in the fixing base 20 with only one bolt 43. At this time, the blade 30 can be the bolt 43. The center of the holder 20 is rotated by 0 to 90 degrees with respect to the central axis of the hub 10. In particular, when the swing is 0 degrees, the blade 30 is in a folded position parallel to the central axis of the hub 10. The third side wall 23 of the fixed seat 20 supports the root 31 of the blade 30. The blade 30 is folded as shown in the third and fourth figures.
復如第二圖，收合的扇葉30應被暫時性的固定，以免運送或吊掛的過程中展開。在每一個固定座30中設置一個暫時性的定位板50擋止於該扇葉30根部以免該扇葉30往上述90度的方向旋擺。該定位板50係靠抵著該固定座20的第一側壁21或第二側壁22，並利用未使用到的孔洞211,221鎖付螺絲51。在展開扇葉30使之得以正常運作之前，拆除該定位板50，使該扇葉30得以展開如第五圖運作。As in the second figure, the folded blade 30 should be temporarily fixed so as not to be unfolded during transport or hanging. A temporary positioning plate 50 is disposed in each of the fixing bases 30 to stop at the root of the blade 30 to prevent the blade 30 from swinging in the above 90 degree direction. The positioning plate 50 abuts against the first side wall 21 or the second side wall 22 of the fixing base 20, and locks the screw 51 by using the unused holes 211, 221 . Before the fan blade 30 is deployed to operate normally, the positioning plate 50 is removed, so that the blade 30 can be deployed to operate as shown in the fifth figure.
上述風車裝置具有可將複數扇葉30收合至與葉轂10之中心軸平行或展開至與中心軸呈垂直相交的技術特徵。此一技術特徵使工程人員可在地面預先進行扇葉30、葉轂10與發電機體60(顯示於第五圖)之組裝，並將複數扇葉30收合，之後將三者之組合體吊掛至塔架61(顯示於第五圖)頂端，將發電機體60與塔架61鎖付固定完成組裝，之後，將該定位板50一一拆除，將扇葉30往90度的方向旋擺展開，並重新鎖付所有用以固定該扇葉30根部31與固定座20的螺栓41,42,43，該風車裝置即可開始運作。The windmill apparatus described above has the technical feature of being able to fold the plurality of blades 30 to be parallel to or parallel to the central axis of the hub 10 to perpendicularly intersect the central axis. This technical feature enables the engineer to pre-assemble the blade 30, the hub 10 and the generator body 60 (shown in the fifth figure) on the ground, and fold the plurality of blades 30, and then hang the combination of the three. Hanging to the top of the tower 61 (shown in the fifth figure), the generator body 60 and the tower 61 are locked and fixed for assembly, and then the positioning plate 50 is removed one by one, and the blade 30 is rotated 90 degrees. Expanding and relocking all the bolts 41, 42, 43 for fixing the blade 30 root 31 and the fixed seat 20, the windmill device can be operated.
與習知技術相較，在地面進行扇葉30、葉轂10與發電機體60的組裝比在高空進行容易得多，且安全性更高。而扇葉30、葉轂10與發電體60之組合體僅需進行一次吊掛作業及一套鎖付固定程序即可將之組立於塔架61的頂端，與習知技術之分次吊掛相較，本案顯然可以縮短吊掛作業的時間。而在吊掛過程中，將扇葉收合並暫時固定，可以減少受風面積，減少吊掛過程中晃動的情形，增加安全性。Compared to the prior art, the assembly of the blade 30, the hub 10 and the generator body 60 on the ground is much easier and safer than at high altitude. The combination of the blade 30, the hub 10 and the power generating body 60 can be assembled on the top end of the tower 61 only by one hanging operation and a set of locking fixing procedures, and is hanged by a conventional technique. In comparison, this case obviously shortens the time for hanging operations. In the hanging process, the fan blades are temporarily combined and fixed, which can reduce the wind receiving area, reduce the shaking during the hanging process, and increase the safety.
本案風車裝置適用於一種升降式塔架，已知昇降式塔架對於風力發電裝置之安裝、維修和颱風來臨之防護均有幫助。將該風車裝置的扇葉30收合，可避免塔架下降時，風葉碰撞地面的問題，且可使塔架下降至最低高度，便於組裝、維修或躲避風侵襲。The windmill device of the present invention is suitable for a lifting tower. The lifting tower is known to be helpful for the installation, maintenance and protection of the typhoon. The fan blade 30 of the windmill device can be folded to avoid the problem that the blade hits the ground when the tower is lowered, and the tower can be lowered to the minimum height for assembly, maintenance or shelter from wind.
雖然本案是以一個最佳實施例做說明，但精於此技藝者能在不脫離本案精神與範疇下做各種不同形式的改變。以上所舉實施例僅用以說明本案而已，非用以限制本案之範圍。舉凡不違本案精神所從事的種種修改或變化，俱屬本案申請專利範圍。Although the present case is illustrated by a preferred embodiment, those skilled in the art can make various forms of changes without departing from the spirit and scope of the present invention. The above embodiments are only used to illustrate the present case and are not intended to limit the scope of the present invention. All kinds of modifications or changes that are not in violation of the spirit of the case are the scope of patent application in this case.
