Wind energy generation system with oil containment features
The patent US11988196B2 describes a wind energy generation system that features a unique design for its tower and nacelle configuration. Central to the system is a tower that supports a rotatable nacelle at its upper portion, which in turn houses a hub that is rotatable around an axis orthogonal to the tower's central axis. The system includes one or more blades attached to the hub. A notable aspect of the design is the incorporation of an oil receiving portion that protrudes outward from the tower's outer wall, encircling it around the central axis. This oil receiving portion is designed to guide oil into the tower through strategically placed opening portions, enhancing the system's functionality and maintenance.
Further details of the design include a sealing mechanism that ensures the space between the oil receiving portion's side wall and a lower tubular portion is completely sealed, preventing leaks. Additionally, the system may feature an oil receiving cover that extends from the lower tubular portion, providing further protection and coverage for the oil receiving portion. The design allows for multiple opening portions to be distributed around the tower's outer wall, facilitating efficient oil management. Overall, the claims outline a comprehensive wind energy generation system that emphasizes structural integrity and effective oil handling, contributing to the operational efficiency of wind energy technologies.
