风轮叶片制造技术

本实用新型专利技术公开了风轮叶片，能够有效解决现有技术中风力发电启动风速要求高，叶片长时间工作易损坏的问题。包括叶柄、连接区域和工作区域，所述工作区域中的叶片弦长长度逐渐减少，由靠近连接区域的１５０ｍｍ减少到末端的２５．５ｍｍ，气流角逐渐减小，由靠近连接区域的３５度减小到末端的０．２６度，叶片上还设有引风层，引风层的厚度也逐渐减小，由靠近连接区域的５０ｍｍ减小到末端的８．５ｍｍ。由于采用了所述结构，本实用新型专利技术的优点是：通过引风层结构进行风向引导，这样就不需要再安装尾翼结构，产品结构得以简化，工作效率予以提高。而且在低风速的情况下也能进行工作。（*该技术在2019年保护过期，可自由使用*）

Blade of wind turbine

The utility model discloses a blade of a wind wheel, which can effectively solve the problems that the wind speed of the wind power generation is high in the prior art and the work of the blade is easy to be damaged for a long time. Including the petiole, connection area and work area, the work area of the blade chord length decreases gradually, from near the connection region of 150mm reduced to the end of the 25.5mm, the flow angle decreases by 35 degrees near the connection region is reduced to the end of 0.26, the blade is also provided with a wind guiding layer, air layer the thickness is reduced gradually decreased from near the connection region of 50mm to the end of the 8.5mm. Because the structure is adopted, the utility model has the advantages that the wind direction is guided by the air guiding layer structure, so that the tail structure is not needed, the product structure is simplified, and the work efficiency is improved. And it works at low wind speeds.
