Embodiment 1

[0043] Please also refer to Figure 1 to Figure 5 , the production method of the wind power blade root prefabricated part provided by the present invention will now be described. The production method of the wind power blade root prefabricated part comprises the following steps:

[0044] S1. Preform the upper substrate 3 and the lower substrate 2, the upper substrate 3 and the lower substrate 2 are both a sheet, and the lower substrate 2 is provided with some first grooves 21;

[0045] S2. Place the lower matrix 2 in the mold 6, place several embedded parts 1 in the first groove 21, fasten the upper matrix 3 onto the embedded parts 1, and The first groove 21 and the second groove 31 are arranged opposite and surround the outside of the embedded part 1;

[0046] S3. Coating adhesives on the lower substrate 2 and the upper substrate 3 respectively, and bonding with the embedded part 1, so that the upper substrate 3, the embedded part 1 and the lower substrate 2 can be bonded ...

specific Embodiment approach

[0061] Further, see image 3 , as a specific implementation of the wind power blade root prefabricated part production method provided by the present invention, it also includes the following steps:

[0062] S3.1 After the embedded part 1 is placed in the first groove 21, a filling part 5 is arranged on one side of the embedded part 1, and the filling part 5 is in contact with the embedded part 1 spliced ​​and embedded in the first groove 21 together. Specifically, the filler 5 is generally made of foam or other light material that can be filled, and it is also arranged in the first groove 21. The filler 5 includes a The filling rod 51 and the filling lugs 52 arranged on opposite sides of the filling rod 51 , the filling lugs 52 of the adjacent filling pieces 5 abut against each other. The thickness of the filling rod 51 is consistent with that of the embedded part 1 , or the thickness of the filling rod 51 is greater than that of the embedded part 1 . The filling rod 51 is...

Embodiment 2

[0069] The present invention also provides another method for producing wind power blade root prefabricated parts. The difference between it and Embodiment 1 is that in step S3, the lower base body 2, the embedded part 1 and the upper layer base body 3 are stacked in advance, and then facing Adhesive is filled between the upper matrix 3 and the lower matrix 2, so that the upper matrix 3, the embedded part 1 and the lower matrix 2 can be bonded. Compared with the way of applying the adhesive multiple times in Example 1, its operation is simpler.

Abstract

The invention provides a prefabricated part of a wind power blade root, a blade root part, a blade and a manufacturing method thereof. A plurality of prefabricated parts of a blade root of the wind power blade are manufactured; outer-layer fiber fabric is laid in the blade root mold, the multiple prefabricated parts are arranged on the outer-layer fiber fabric, and the adjacent prefabricated partsare spliced; an inner-layer fiber fabric is laid on the spliced prefabricated part; pouring into the blade root mold is performed, and molding is achieved to obtain the blade root. A part of the laying layers are prefabricated in advance, assembled and formed and then placed into the blade root mold to be integrally formed with the remaining laying layers, difficulty and the time for later pouring forming can be reduced, a block overlapping mode is adopted in the thickness direction, multiple sections of prefabricated parts are spliced in the circumferential direction, and assembling difficulty can be greatly reduced. Standardized and modular production is adopted, manufacturing can be conducted in advance, defects are easy to check and control, risks are reduced, production efficiency can be further improved, universality of different types can be achieved, and standardized management is facilitated.

Description

technical field [0001] The invention relates to the technical field of wind power generation devices, in particular to a prefabricated part of a blade root of a wind power blade, a blade root component, a blade and a manufacturing method thereof. Background technique [0002] Wind power generation is one of the fastest growing resource utilization methods in the world today. As an important part of wind turbines, wind power blades affect the development of the entire industry. With the expansion of the offshore market and the design of longer blades, the load on the blade root becomes larger and larger, which puts higher requirements on the production and processing of the root of wind turbine blades. However, due to the continuous expansion of the diameter of the blade root, the assembly of the embedded parts of the blade root is time-consuming and laborious, which brings great difficulty to the operation of personnel. At present, the height of some semicircles even exceed...
