[0002] Wind power generation is a renewable energy technology that converts wind energy into electricity. Wind power drives the rotation of wind turbines, which then use rotating machinery to convert mechanical energy into electricity. Wind turbine concrete columns are structures used to support wind turbines. Typically composed of concrete columns, steel pipes, or rebar, they are used to secure and support the blades and generator. Concrete columns offer advantages such as high strength, durability, and ease of construction. During installation, they can be cast on-site or prefabricated in a prefabricated plant. They can also be customized to suit different installation environments based on terrain and environmental conditions.

[0003] The connection method between the existing wind power generation concrete columns and wind power generation columns is usually flange connection, but the simple flange connection may loosen after long-term use, posing a safety hazard. In addition, the energy storage modules of the existing wind power generation columns are generally exposed to the open air and are easily damaged by rain. The energy storage modules are exposed to the outside and are more likely to encounter collisions. The existing wind power generation concrete columns are directly inserted into the ground, and their firmness needs to be strengthened. Therefore, a wind power generation concrete column is proposed to address the above problems. Utility Model Content
