Description

Technical Field

[0001] The utility model relates to the field of fan installation equipment, in particular to a steel-concrete tower barrel bottom foundation reinforcement and waterproof structure. Background Technique

[0002] The fan tower barrel is a tower-shaped structure that supports the wind power generation unit. Its main functions and characteristics are as follows: It provides stable support for the nacelle and impeller of the wind turbine. Usually, the fan tower barrel is relatively high in height, which can lift the wind turbine to a certain height so that the impeller can access stronger and more stable wind resources. It bears the weight of the wind power generation unit, including the weights of the main components such as the nacelle, impeller, and generator, and at the same time, it also bears various dynamic loads generated during the rotation of the wind wheel and the lateral force of the wind acting on the tower barrel.

[0003] Rusting of the rainwater at the screw connection position of the fan tower barrel base can easily cause the following problems: Rust will make the surfaces of the bolts and nuts rough, reducing the effective contact area, thereby reducing the connection strength of the screwed part. During the operation of the fan, especially when subjected to external forces such as wind and vibration, it may cause the connection to loosen or even fail. As the rusted area continuously increases, the materials of the bolts and nuts will gradually be corroded, and their mechanical properties will decline, further weakening the bearing capacity of the connection.
