Method for recycling retired or damaged wind power blades to manufacture wind prevention and sand fixation barrier
The invention discloses a method for recycling retired or damaged wind power blades to manufacture a wind prevention and sand fixation barrier. The method for recycling the retired or damaged wind power blades to manufacture the wind prevention and sand fixation barrier comprises the steps that the retired or damaged wind power blades with blade roots removed are cut and segmented, and segmented blades are manufactured; according to the structural parameters of the wind prevention and sand fixation barrier to be manufactured, the optimal cutting path of the segmented blades is determined, the segmented blades are cut, the design precision can be improved through methods such as three-dimensional digital modeling, and a blank of the wind prevention and sand fixation barrier is obtained; carrying out crushing, crushing and mould pressing remanufacturing on excess materials which are too large in curvature or cannot be cut so as to obtain a green body; and processing the green body to obtain the wind prevention and sand fixation barriers with different sizes and porosities. The wind prevention and sand fixation barrier is manufactured by utilizing the advantages of high strength, harsh natural condition resistance and the like of a fan blade material, the problem of recovery treatment of retired wind power blades can be solved, the problem of shortage of wind prevention and sand fixation materials in deserts and gobi areas can also be solved, and the wind prevention and sand fixation barrier can be recycled and has no environmental pollution risk.
本发明揭示了一种退役或损毁风电叶片回收制作防风固沙障的方法。退役或损毁风电叶片回收制作防风固沙障的方法包括：将去除叶根的退役或损毁风电叶片进行切割分段，制成分段叶片；根据拟制成防风固沙障的结构参数，对分段叶片确定最优切割路径并切割，可采用三维数字建模等方法提高设计精度，获得防风固沙障的坯体；对于曲率过大或无法切割的余料，进行破碎、粉碎、模压重制获得坯体；对坯体进行加工，制得不同尺寸、孔隙度的防风固沙障。本发明利用风机叶片材料强度高、耐严酷自然条件等优势，制作防风固沙障，可以解决退役风电叶片回收处理的难题，也能解决沙漠、戈壁地区防风固沙材料短缺的问题，并且可以再次回收利用，无环境污染风险。
