Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a secondary protection ring structure for a prestressed anchor bolt wind turbine foundation. Background Technology

[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. A wind turbine consists of a rotor and a generator. The rotor comprises blades, a hub, and reinforcing components. It generates electricity by rotating the blades under wind power and by rotating the generator head. The wind power supply consists of the wind turbine, the tower supporting the generator, a battery charging controller, an inverter, a load unloader, a grid connection controller, and a battery bank. When a wind turbine generates electricity, it must maintain a constant output frequency. This is essential for both grid-connected wind turbines and wind-solar hybrid power generation. To ensure a constant frequency, one method is to maintain a constant generator speed, i.e., constant speed and constant frequency operation. Since the generator is driven by the wind turbine through a transmission device, this method undoubtedly requires a constant wind turbine speed, which affects the wind energy conversion efficiency. Another method is to allow the generator speed to vary with wind speed, using other means to maintain a constant output frequency, i.e., variable speed constant frequency operation. With societal development, secondary protection ring structures are used when prestressed anchor bolt wind turbine foundations require protection.

[0003] Existing equipment, such as CN211037032U, is an application of a protective structure for prestressed anchored wind turbine foundations, belonging to the field of building engineering structures. The secondary protective ring structure for prestressed anchored wind turbine foundations includes a flexible filling structure layer and a high-strength self-leveling secondary grouting protective layer. The flexible filling structure layer is set on the top surface of the wind turbine foundation and is located close to the outer side of the self-leveling secondary grouting protective layer within the pressure zone. The high-strength self-leveling secondary grouting protective layer surrounds the outer side of the flexible filling structure layer. This utility model has the following advantages: 1. It overcomes the common shortcomings of safety hazards, quality defects, and poor weather resistance caused by post-construction stress damage to the high-strength secondary grouting protective layer of prestressed anchored wind turbine foundations. 2. It has good structural integrity, safety, durability, and weather resistance. 3. It has good social and economic benefits. 4. It allows for rapid construction and has small dimensional deviations.

[0004] When workers need to protect the foundation of a wind turbine, they install a protective ring structure on the foundation to protect it. However, during use, the protective ring structure may be damaged by creatures such as ants or rats, causing the sealing material on the surface of the protective ring structure to be damaged, which in turn affects the normal operation of the wind turbine.
