The scheme has the following advantages: (1) the blades are of a splicing structure, so that the transportation and the assembly are convenient; (2) the blade wing is of a cavity structure formed by splicing a plurality of sandwich plates and arc plates, and the sandwich plates are adopted, so that the strength is ensured, and the light weight can be greatly improved; the lighter the blades are, the easier the blades are blown by wind to rotate for power generation, namely breeze can generate power, and annual power generation hours are greatly increased; (3) through setting up the stem, can strengthen the bulk strength of blade to and can strengthen rigidity and stability at splice section department.
Specifically, the sandwich plate 3 is a planar sandwich plate, which is easier to manufacture and greatly reduces the manufacturing cost compared with the existing curved plate body, so that the blade is manufactured by adopting a lightweight material in the embodiment, and the limitation of the material in the aspect of shape is overcome. The plane sandwich plates are connected through the arc plates.
Wherein, the lobe of a leaf section 12 can be multistage mosaic structure, and the concatenation section quantity of this embodiment can be selected as required, and length is longer, and the concatenation section is more.
Since the size of the blade is gradually reduced from the blade root section 11 to the blade tip section 13, the blade stem 2 of the present embodiment has a conical tube structure, which may be a conical tube structure or a polygonal conical tube structure. The blade stem 2 is of a conical pipe structure and is supported and connected in the cavity of the blade wing 1, so that the overall strength of the blade wing can be improved, and the blade wing is not only locally reinforced like a reinforcing plate; on the other hand, the rigidity and stability at the splice section can be enhanced.
Further, the leaf and stem are in a segmented structure. The segmented structure means that each segment of the leaf root segment 11, the leaf middle segment 12 and the leaf tip segment 13 is provided with the leaf stem 2, instead of a whole root penetrating between the leaf wings, when a certain segment needs to be replaced, the segment and the leaf stem in the segment are integrally detached without replacing the whole leaf wings, so that the cost is saved, and the working efficiency is greatly improved.
Preferably, the length of the stem of each section of the blade wing satisfies: when the adjacent sections are connected, the leaves and stems are exactly butted together. The length of the leaf stem can be equal to that of each section of the leaf wing, and can also be greater than or less than that of each section of the leaf wing as long as the butt joint with the leaf stem in the adjacent section is satisfied. In order to facilitate the connection between the leaves and stems, the end of the preceding leaf and stem is matched with the head of the following leaf and stem in size. The embodiment is provided with the leaf stem in each section of the leaf wing, so that the rapid connection is convenient. Because the blades and the stems are arranged inside the blade wings, the adjacent blades and stems are preferably connected in a welding or splicing mode, and therefore the assembling speed can be increased.
