Description

Technical Field

[0001] This utility model belongs to the field of offshore wind turbine technology, specifically relating to a pipe node of a jacket and the jacket itself. Background Technology

[0002] Offshore wind turbine foundations are a crucial component of wind farm design. Offshore wind turbines are massive, and their foundations must withstand 10⁷ to 10⁸ cycles of wind and wave loads throughout their lifespan, while also resisting extreme loads such as storm surges. These complex load conditions place stringent requirements on the horizontal bearing capacity and deformation characteristics of the wind turbine foundation piles. For example, DNV GL stipulates that the cumulative rotation angle of the offshore wind turbine foundation at the seabed mud surface should not exceed 0.25°. Design practice shows that the ultimate horizontal bearing capacity of the wind turbine foundation piles is no longer the dominant design variable; horizontal and rotational deformation are the key design considerations. Currently, common nearshore wind turbine foundation types both domestically and internationally include ultra-large diameter monopile foundations, tripod foundations, jacket foundations, and pile groups. Jacket foundations were initially used to support offshore oil and gas platforms. In recent years, this foundation type has been increasingly adopted for wind farms in medium-deep waters in the offshore wind power industry. However, the nodes of wind turbine jackets in related technologies, due to their unique geometry and stress characteristics, become weak points of stress concentration, which are prone to large deformation or even damage, thereby affecting the stability and service life of the entire wind turbine generator. A search revealed that CN119021171A discloses a node reinforcement component for wind turbine jackets, a wind turbine jacket, and a wind turbine generator. The node reinforcement component includes an inner tube, an outer tube, and a filler. The inner tube is arranged in a circular manner and includes a first tube portion extending in a first direction and a second tube portion extending in a second direction. The first and second directions intersect, and the first and second tube portions are connected. At least a portion of the outer tube is arranged around the outer periphery of the first tube portion, and at least another portion of the outer tube is arranged around the outer periphery of the second tube portion. A filling gap is defined between the outer tube and the inner tube. The filler is disposed within the filling gap to constrain the relative deformation of the inner and outer tubes. The node reinforcement component according to the present invention can wrap around the nodes of the wind turbine jacket where the extension direction changes, thereby strengthening the nodes and enhancing the overall rigidity and stability of the wind turbine jacket. Combined with the filler in the gap, it further improves the mechanical properties and durability of the node reinforcement component. However, its drawback is that when the first ear and the second ear are contacted and fixed, they cannot be positioned relative to each other, making assembly cumbersome. It requires holding the two sets of outer pipes to perform the assembly, which is quite troublesome and needs to be improved. Therefore, it is of great importance to design a pipe node for the jacket and the jacket itself to solve the above-mentioned defects. Utility Model Content
