Problems solved by technology
The main problems of the above method are: the quality of hand lay-up is relatively poor, there are many air bubbles, and the impregnation of glass fiber cloth is poor. The production quality depends on the worker's operational skills and sense of responsibility. It takes about one year to train an excellent hand-lay-up operator
In addition, the appearance of the product after hand layup is not good, and the overlap of hand layup affects the overall aesthetic feeling of the product

Embodiment Construction
[0030] The root baffle structure and installation method of the fan blade in the embodiment of the present invention, the root baffle is fixed on the inner circular wall of the blade root through the root baffle flange and the root baffle bracket, replacing the traditional hand lay-up fixing method , simplifies the installation process of the root baffle structure, improves the installation standardization of the root baffle structure, and makes the root baffle structure clean and beautiful after installation.
[0031] In addition, it should be noted that in the present invention, the blade root refers to the substantially cylindrical part located at the lower part of the blade, and the blade root refers to the lower end of the blade, which is relative to the blade tip. In the present invention, The blade root and blade tip are mainly used to describe the relative positional relationship and direction of each component in the entire blade. The root baffle structure and install...

The invention provides a fan blade root baffle plate structure and an installation method thereof. The fan blade root baffle plate structure comprises a root baffle plate, and further comprises a root baffle plate flange and root baffle plate brackets, wherein the root baffle plate flange is a cylinder; the outer cylinder wall of the root baffle plate flange is fixedly connected with the inner circular wall of a blade root; a web plate is arranged on the inner cylinder wall of the root baffle plate flange; one surface of the root baffle plate is butted against the web plate; and multiple root baffle plate brackets are arranged at the edge of the other surface of the root baffle plate, and are used for fixing and mounting the root baffle plate on the inner circular wall of the blade root. In the fan blade root baffle plate structure and the installation method thereof, as the root baffle plate is fixed on the inner circular wall of the blade root through the root baffle plate flange and the root baffle plate brackets, a traditional manual pasting fixing mode is replaced, the installation process of the root baffle plate structure is simplified, the installation standardization degree of the root baffle plate structure is improved, and the root baffle plate structure is tidy and beautiful after the installation is finished.
Description
technical field [0001] The invention relates to a root baffle structure of a fan blade and an installation method thereof, and belongs to the technical field of wind power generation. Background technique [0002] The root baffle of the fan blade (hereinafter referred to as the root baffle) is fixed to the root of the blade by adhesive glue, the root baffle is circular, and the root baffle is installed about 1m away from the blade root section. There is a circular hole on the root baffle, through which blade maintenance personnel can enter the interior of the blade for maintenance. [0003] In the prior art, the outer wall of the root baffle is directly bonded to the inner circular wall of the blade root, and the root baffle is usually thinner, resulting in a smaller bonding area between the outer wall of the root baffle and the inner circular wall of the blade root, making the adhesion Junction reliability is poor. In order to improve the bonding reliability, hand-laid gl...
