Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine tower bases and relates to a device for installing and fixing an anchor plate of a wind turbine tower base. Background Art

[0002] The wind turbine tower base is an important part of the wind power generation system. It bears the weight of the entire wind turbine and fixes it to the ground to ensure the stable operation of the wind turbine. Generally speaking, the wind turbine tower base is made of concrete or steel structure, and its design needs to consider many factors, including geological conditions, wind force, soil bearing capacity, etc. The design of the base must also meet relevant standards and specifications to ensure its safety and stability. If the wind turbine tower base cannot be fixed to the ground, a series of serious problems will occur.

[0003] If the tower base cannot be fixed to the ground, the stability of the wind turbine will be affected. Under the action of wind, the generator set may shake or vibrate, which will not only shorten the service life of the equipment, but also cause mechanical failure or damage. In addition, an unstable tower base may also cause the wind turbine to collapse under extreme weather conditions, posing a threat to the surrounding environment and personnel safety.

[0004] Secondly, poor tower base fixing will affect the power generation efficiency of wind turbines. Since the generator set cannot be stably fixed on the ground, the energy conversion efficiency under the action of wind will be greatly reduced, resulting in reduced power generation. This will not only affect the economic benefits of the wind farm, but may also affect the stable operation of the entire power system.

[0005] In addition, the tower base fixing problem may also cause a series of safety problems. For example, if the base is not fixed firmly, the wind turbine may overturn in strong winds, causing damage to surrounding personnel and equipment. At the same time, an unstable tower base may also cause safety hazards such as electrical failures or fires.

[0006] In summary, the inability of the wind turbine tower base to remain fixed to the ground will cause a series of serious problems, including affecting the stability, power generation efficiency and safety of the equipment. Therefore, there is an urgent need for an installation and fixing device for the anchor plate of the wind turbine tower base to solve the above problems. Utility Model Content
