Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine anchor plates, and particularly relates to an adjustable wind turbine tower base anchor plate. 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 (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. Before fixing the base of the wind turbine tower, it is necessary to fix the anchor plate to the ground, and then dock the anchor plate with the base of the wind turbine tower to achieve stable installation of the wind turbine tower and ensure the normal operation of the wind turbine in the later stage. However, the commonly used anchor plate of the wind turbine tower base cannot be adjusted after installation. When the original anchor plate is not stable enough due to environmental changes and other conditions, it may not be possible to provide good stability support for the wind turbine tower. The wind turbine may shake during use, which will affect its actual operation and cause its power generation efficiency to be insufficient.

[0003] Secondly, the shaking of the wind turbine tower will aggravate the shaking of the anchor plate, making the anchor plate even more unstable. Under long-term action, the wind turbine tower may fall down, causing unnecessary losses and safety hazards.

[0004] In addition, when the above situations occur, it is necessary to arrange maintenance personnel to perform corresponding maintenance operations, and the unadjustable anchor plate will make the maintenance more difficult and require a longer maintenance time.

[0005] In summary, there are some problems in the use of the wind turbine tower base anchor plate that cannot be adjusted, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
