Description

Technical Field

[0001] This utility model relates to the field of wind power anchor plate technology, and in particular to a wind power anchor plate anti-shear and anti-loosening component. Background Technology

[0002] Wind turbine anchor plates are core load-bearing components in the foundation structure of wind turbine generators. They are mainly used to connect the wind turbine tower to the concrete foundation, effectively transferring vertical loads, horizontal wind loads, and vibration loads from the tower to the foundation, ensuring the installation stability and long-term operational safety of the turbine in complex outdoor environments. During the operation of wind turbine generators, anchor plates must withstand continuously changing dynamic loads, among which shear force is a key force affecting their structural integrity. If the anchor plate lacks reliable shear protection, it is prone to problems such as slippage of connectors and structural misalignment under shear force, leading to anchor plate failure, causing serious safety accidents such as tower tilting or even turbine collapse. Therefore, it is necessary to strengthen the anchor plate's shear resistance using specialized shear-resistant and anti-loosening components to ensure the structural load-bearing reliability of the wind turbine foundation.

[0003] Existing wind turbine anchor plates mostly employ a single shear-resistant structure design, such as using only ordinary bolts or washers for shear limiting. Their force transmission path is relatively simple, failing to evenly distribute the shear load borne by the anchor plate to multiple load-bearing points. Under the repeated dynamic loads generated during the long-term operation of wind turbine generators, localized stress concentration is prone to occur in the components, leading to premature fatigue damage of the shear-resistant components. This not only makes it difficult to withstand the instantaneous high-intensity shear forces under extreme conditions such as strong winds and turbulence, but also results in insufficient load-bearing margin and inadequate shear strength, easily causing deformation and tilting, affecting service life. Furthermore, the anchor plate's installation anti-loosening capability is insufficient, providing inadequate fixation protection and shortening the component's lifespan. Therefore, we propose a wind turbine anchor plate shear-resistant anti-loosening component to address these problems. Utility Model Content
