They are also the main basis for measuring the design and technical level of wind turbines. Among them, blades are an industry with high certainty, large market capacity and clear profit model among wind turbine components. Therefore, various types of wind turbine blade root baffles stand out in the market.

[0003] For example, the Chinese patent number CN215521148U is a reinforced blade root baffle specially used for wind turbine blades. In this utility model, the reinforcement of the blade root baffle body is achieved by a limiting ring body and a fixing ring body, which can improve the strength of the reinforced blade root baffle body. However, in this utility model, the four corners of the blade root baffle need to be fixed in sequence by bolts and reinforced by threads, which increases the labor workload of the staff in assembly, reduces the work efficiency in disassembly and assembly, and is not conducive to the use of users. Therefore, a reinforced composite blade root baffle is proposed to solve the above problems. Utility Model Content

[0030] When implementing, follow these steps:

[0031] 1) First, rotate the four connecting rods 33 in sequence to change the position of the limiting leaf rod 36;
