Description

Technical Field

[0001] This utility model belongs to the technical field of anchor plate and anchor bolt assembly, and relates to an anchor plate and anchor bolt assembly for a wind turbine tower base. Background Technology

[0002] An anchor plate and anchor bolt assembly is a device used to connect and secure structural components, consisting of an anchor plate and anchor bolts. The anchor plate is typically a metal plate that contacts the surface of a substrate such as concrete or rock, transmitting tensile or shear forces. The anchor bolt is a metal rod, fixed at one end to the anchor plate and embedded in the substrate at the other end, bearing tensile or shear forces through friction or adhesion with the substrate. A stable connection between the anchor plate and the buried anchor bolts in a wind turbine base is crucial for the safety and stability of the entire wind turbine generator set. If the anchor plate fails to connect stably to the buried anchor bolts, a series of serious problems may arise.

[0003] When wind turbines are operating, especially in windy weather, they are subjected to enormous wind forces and torques. If the connection between the base anchor plate and the buried anchor bolts is unstable, these forces cannot be effectively transmitted, making the entire structure prone to deformation or damage under stress, seriously affecting the normal operation of the wind turbine generator set.

[0004] If the anchor plate and anchor bolt are not securely connected, the wind turbine may shake or vibrate during operation. This will not only affect the power generation efficiency, but may also cause the internal components of the unit to loosen or be damaged, leading to a greater safety accident.

[0005] Due to unstable connections, the unit may frequently malfunction or be damaged during operation, requiring frequent maintenance and replacement of parts. This not only increases maintenance costs but may also affect the long-term stable operation of the wind turbine generator. Therefore, there is an urgent need for an anchor plate and anchor bolt assembly for the wind turbine generator tower base to solve the above problems. Utility Model Content
