Wind power blade preparing method for reducing residual glue residues

Abstract

The invention discloses a wind power blade preparing method for reducing residual glue residues. By means of the method, a glue blocking edge (7) with glass fiber reinforced plastic with the width being 10 mm to 20 mm is prefabricated on the upper edge of a bonding corner (5) at the front edge of a lower shell (2), and the glass fiber reinforced plastic on the glue blocking edge (7) is located between an upper shell (1) and the lower shell (2) of a wind power blade, and the edge of the glue layer is bonded; then a glue blocking bar (10) is stuck to or fabricated at the tail end of a web folded edge (9) of a web (8); a sponge bar is bonded to the rear edge position of the lower shell (2); and finally the upper shell (1) and the lower shell (2) of the wind power blade are lifted and closed, bonding is completed, and surplus bonding glue is discharged out. The whole technological design is reasonable, operation is convenient, the work efficiency is high, the cost is low, the weight of the blade can be reduced, and the quality of the blade is improved.

Description

technical field [0001] The invention relates to a method for preparing wind power blades, in particular to a method for preparing wind power blades with reduced residual glue residue, and belongs to the field of wind power generation. Background technique [0002] Wind turbine rotor blades rely on their special aerodynamic shape to capture wind energy and convert it into mechanical energy. As a component of the wind turbine to capture wind energy, the wind turbine blade plays an extremely important role in the wind turbine. Its root is connected to the hub through bolts and directly bears force on the turbine. On the premise of meeting the power generation capacity, it is hoped that the weight of the blades should be as light as possible, so that the load on the hub will be smaller and the service life of the unit will be longer. [0003] Weight control is particularly important during blade production. As the main raw material of the blade, the adhesive glue accounts for ...

Problems solved by technology

Therefore, it is necessary to clean up the extruded adhesive before the adhesive is cured. Otherwise, the weight will be increased, and the residual glue will cause fatal damage to the unit once it falls off during the long-term operation of the unit. Quality hidden danger

However, the closer the blade is to the tip, the narrower the space is. People can only enter about 1 / 3 of the area to clean up the residual glue. How to clean the glue in the other 2 / 3 areas has been puzzling the blade manufacturing technicians for a long time. , there has been no efficient and simple way to
