以風力發電為例，本第一實施例在運作時，該等葉片41受到風力推動而帶動該轉動單元2相對於該支撐單元1旋轉，由於該轉動單元2與該支撐單元1只依靠該第一套合部13與該第二套合部23的錐尖與錐槽底相接觸，減少兩者連接的摩擦，並藉由該等第一磁鐵31與該等第二磁鐵32產生的斥力使該轉動單元2不會左右傾倒，使該轉動單元2更滑順地相對於該支撐單元1旋轉。以圖3的該等葉片單元4為例，位於左側的該葉片41的該迎流體面413具有較大的受風面積，位於右側的該葉片41的該第二葉部412朝該旋轉方向尖突，有效地減少風阻。該第一葉部411與該第二葉部412的配合更有效率地帶動該轉動單元2旋轉。Taking wind power generation as an example, during the operation of the first embodiment, the blades 41 are driven by the wind to drive the rotating unit 2 to rotate relative to the supporting unit 1. Since the rotating unit 2 and the supporting unit 1 only rely on the first The taper tip of the set of engaging portions 13 and the second set of engaging portions 23 are in contact with the bottom of the tapered groove, reducing the friction between the two, and using the repulsive force generated by the first magnets 31 and the second magnets 32 The rotating unit 2 does not tilt left and right, so that the rotating unit 2 can rotate more smoothly relative to the supporting unit 1. Taking the blade unit 4 in FIG. 3 as an example, the fluid-facing surface 413 of the blade 41 on the left side has a large wind receiving area, and the second blade portion 412 of the blade 41 on the right side is pointed toward the rotation direction. Sudden, effectively reducing wind resistance. The cooperation of the first leaf portion 411 and the second leaf portion 412 drives the rotating unit 2 to rotate more efficiently.

The second fitting portion 23 protruding downward from the bottom surface of the element 212 and having a conical column shape.

該凸塊部212插置於該容槽120，但兩者藉由該第一套合部13與該第二套合部23的支撐而彼此不接觸，並保持能供潤滑油容置的空間。該容槽120除了能容納潤滑油外，配合該凸塊部212能在該轉動單元2受到較大的外力而傾倒時限制傾倒的角度，避免該套筒22與該支撐單元1碰撞。The bump portion 212 is inserted into the receiving groove 120, but the two are not in contact with each other by the support of the first fitting portion 13 and the second fitting portion 23, and maintain a space for accommodating the lubricant. . In addition to accommodating the lubricating oil, the accommodating groove 120 can cooperate with the convex portion 212 to limit the tilting angle when the rotating unit 2 is tilted by a large external force, so as to prevent the sleeve 22 from colliding with the supporting unit 1.

參閱圖5，本新型流力發電用葉片裝置的一個第三實施例，與該第二實施例的不同之處在於：該容槽120與該凸塊部212的結構。Referring to FIG. 5, a third embodiment of the novel blade device for fluid power generation is different from the second embodiment in the structure of the receiving groove 120 and the protruding portion 212.

The first fitting portion 13 is recessed on the top surface of the positioning post 122. A positioning groove 213 for inserting the positioning post 122 is recessed on the bottom surface of the protruding portion 212, and has a positioning groove surface 214 defining a top edge of the positioning groove 213. The second engaging portion 23 protrudes downward from the positioning groove surface 214 and is rotatably assembled with the first engaging portion 13. The accommodating groove 120 and the positioning groove 213 can accommodate the lubricating oil 6, and the positioning post 122 and the locating groove 213 can make the rotating unit 2 and the supporting unit 1 more difficult to be combined and rotated.

要特別說明的是，上述所有實施例中，該第一套合部13與該第二套合部23的凸柱與凹槽的結構是可以對調的，在使用上一樣可以達到讓該轉動單元2相對於該支撐單元1旋轉的目的，且兩者也不局限於呈圓錐狀，也可以呈半圓球狀，一樣能令該第一套合部13與該第二套合部23以較小面積的接觸並達到旋轉的效果。It should be particularly noted that, in all the above embodiments, the structures of the convex posts and grooves of the first fitting portion 13 and the second fitting portion 23 can be reversed, and the rotating unit can be achieved in use as well. The purpose of 2 relative to the supporting unit 1 is not limited to being conical, but may also be semi-spherical, which can make the first fitting portion 13 and the second fitting portion 23 smaller. The area touches and achieves the effect of rotation.

綜上所述，本新型流力發電用葉片41裝置的功效在於：藉由該第一套合部13與該第二套合部23支撐並連接該轉動單元2與該支撐單元1，並利用該平衡單元3產生的斥力使該套筒22不易左右傾倒而與該支撐單元1產生摩擦，進而使該轉動單元2能不依靠軸承或其他輔助元件便能滑順地相對於該支撐單元1旋轉。應用在發電裝置上能提昇發電的效率，且減少保養的需求。因此，確實能達到本新型的目的。To sum up, the effect of the novel blade device for fluid power generation 41 is to support and connect the rotating unit 2 and the supporting unit 1 through the first fitting portion 13 and the second fitting portion 23, and use The repulsive force generated by the balancing unit 3 makes it difficult for the sleeve 22 to fall sideways and cause friction with the supporting unit 1, so that the rotating unit 2 can smoothly rotate relative to the supporting unit 1 without relying on bearings or other auxiliary components. .
