Problems solved by technology

The aging resistance of the polyurethane leading edge protective film is generally poor, and the protective film will be damaged after about 5 years of pasting. If the protective film is repaired, more maintenance costs will be incurred; During the coating process, it is necessary to ensure that the protective coating on the leading edge of the blade has sufficient thickness and high coating quality. Often, the coating effect is not good due to the low proficiency of the workers, which affects the protective effect
In addition, if the paint film is damaged, more maintenance costs will be incurred

Abstract

The invention relates to a blade of a wind turbine generator set, a manufacturing method of the blade and the wind turbine generator set. The blade of the wind turbine generator set comprises a protection device arranged at a front edge of the blade, the protection device is of a laminated structure which at least comprises an elastic layer and a hard layer, and the elastic layer and the hard layer are arranged successively from a surface of a shell of the blade to a direction distant from the surface of the shell of the blade. The blade has the advantages that the hard layer is high in hardness and weatherability and is less prone to deforming or breaking during long-time operation of the blade, the elastic bottom layer can buffer the impact of wind, sand, rain, insects and the like, andthrough synergistic effect of the hard layer and the elastic layer, the front edge of the blade can be protected effectively, a wing shape of the blade can be kept unchanged, a good aerodynamic performance of the blade can be kept for a long time, and high generating efficiency of the wind turbine generator set can be kept.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a blade of a wind power generating set and a method for manufacturing the blade. Background technique [0002] In recent years, wind power, as a clean energy, has developed rapidly. When the wind turbine is working normally, the blade tip speed can reach 70-80m / s, which is equivalent to the speed of a high-speed rail at 300 kilometers per hour. In the natural environment, wind and sand, rain, insects or other suspended particles in the air cause the blade to be worn, especially in the leading edge area (within the range of about 20-30m from the blade tip to the blade root), and the leading edge bonding part will be therefore Cracking and corrosion lead to changes in the airfoil of the blade. Due to the change of the airfoil, the resistance of the airfoil will increase and the aerodynamic performance will drop significantly. Blade leading edge protection is crucial to improv...
