Description

Technical Field

[0001] The utility model relates to the technical field of wind turbines, in particular to a pile foundation structure for wind turbines in large-thickness deadweight collapsible loess areas. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of components such as a wind rotor, a generator, a rectifier, a tower, a speed limit safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium.

[0003] For example, a wind turbine pile foundation structure with publication number: CN220686048U includes a pile body, an adjusting mechanism is arranged above the pile body, the adjusting mechanism includes an adjusting rod, the adjusting rod is slidably connected to the inner side of the pile body, and a cylinder is welded below the adjusting rod. During the process of power generation, the wind turbine pile foundation structure uses the cylinder to drive the adjusting rod to move and adjust, thereby adjusting the height of the pile body. At the same time, the movable rod is inserted into the inner side of the movable groove. Under the interaction between the movable groove and the movable rod, the position of the adjusting rod can be fixed to avoid the height of the wind turbine pile being fixed during the process of power generation. Therefore, it will be more troublesome and easy to fall down when lifting and installing the wind turbine pile. At the same time, when the wind force is strong, the wind turbine pile is prone to dangerous falling, which is not conducive to adjusting the height of the wind turbine pile according to the environment.

[0004] However, when the above device is installed on an uneven ground, the generator is prone to tilt, which affects the efficiency of power generation and has poor applicability. Utility Model Content
