Embodiment 1
[0036] The invention discloses a repair method for lack of glue behind a non-destructive flaw detection girder of a wind power blade. The present invention comprises the steps:
[0037] S1, positioning outside the lack of glue point: such as figure 1 As shown, after the non-destructive testing of the blade, it is found that there is a lack of glue in the bonding area between the first shell plate 1 and the web 3, and the position of the lack of glue point 4 is analyzed through the detection waveform of the non-destructive testing equipment, and it is easy to find the lack of glue Use a marking pen to mark the missing glue position on the outer surface of the first housing plate 1, and then place a first magnet 5.
[0038] S2. Positioning within the lack of glue point: continue to refer to figure 1 , the second housing 2 is the housing surface opposite to the first housing plate 1, and the second magnet 14 is sent through the second housing plate 2 to the web 3 where the glue...

The invention discloses a wind power blade nondestructive inspection girder rear glue shortage maintenance method. The method comprises the following steps that S1, external positioning of a glue shortage point is conducted: the glue shortage point on the outer surface of a first shell plate is marked with a first magnet; S2, internal positioning of a glue shortage point is conducted: a second shell plate and the first shell plate are oppositely arranged, a second magnet penetrates through the second shell plate to be fed into a web where the glue lacking point is located, the first magnet and the second magnet attract each other, and a glue lacking mark is made at the position of the second magnet; and S3, glue supplementing is conducted: glue injection holes are drilled in the glue shortage marks, and glue is injected. According to the wind power blade nondestructive inspection girder rear glue shortage maintenance method, a window does not need to be formed in a shell, large-range damage to the shell is avoided, an operator does not need to enter the shell to use equipment, the method is simple and convenient, the maintenance efficiency is greatly improved, and the repair success rate is increased.
Description
technical field [0001] The invention relates to a repair method for lack of glue behind a non-destructive flaw detection girder of a wind power blade. Background technique [0002] Wind energy is a green renewable energy with good development prospects. Wind power has the potential to become an important part of the future energy structure. Therefore, the development of wind power generation has also attracted much attention, and fan blades are an important part of wind turbines. As a composite material product, wind power blades are made of resin as a matrix, glass fiber cloth as a reinforcement, and vacuum infusion. The shell area will also be filled with some Balsa and PVC, while the seam area will be bonded with adhesive. From a macro point of view, a wind turbine blade is mainly composed of two parts, the shell and the web, and the bonding between the web and the shell plays a very important role in the structure of the blade. Once there is a defect in the bonding are...
