Technical Field
[0001] This utility model relates to the field of wind turbine generator installation technology, specifically to a mounting structure for a wind turbine generator base. Background Technology
[0002] Offshore wind power, as an important direction for clean energy development, has become a key area in the global energy transition due to its abundant wind energy resources and broad development prospects. The construction of offshore wind power stations typically adopts an engineering model of prefabrication on land and installation at sea, with the alignment and installation of the foundation and the upper generator units being the core of the entire construction process. Currently, the industry generally uses a circular flange connection scheme, achieving a reliable connection of the structure through precise alignment. This design, while ensuring structural strength, also places extremely high demands on the assembly accuracy.
[0003] Currently, offshore wind turbine installation faces significant technical challenges: the upper-level generator unit structure is massive and extremely heavy, making position adjustment difficult once it comes into contact with the foundation flange during hoisting; precise alignment of the flange holes relies entirely on manual guidance, introducing considerable uncertainty into the installation process; furthermore, the complexity of the offshore operating environment further increases the difficulty of alignment operations. These factors not only prolong the offshore operation window but also increase installation costs and risks. Therefore, we propose a mounting structure for wind turbine generator sets. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mounting structure for a wind turbine generator set, comprising a wind turbine tower and connecting components; Wind turbine tower: A pipe pile is provided at the lower end of the wind turbine tower. A guide component is installed at the lower end of the wind turbine tower. A fixing component and a fastening component are installed on the surface of the pipe pile. The fixing component and the fastening component cooperate with each other. The connecting assembly includes a connecting ring, a fixing ring, a sliding plate, a spring, and a locking post. A connecting ring is fixed to the lower end of the surface of the wind turbine tower, and a fixing ring is fixed to the upper end of the surface of the pipe pile. The lower end of the connecting ring has evenly distributed connecting grooves, and a locking post is slidably connected inside each connecting groove. A guide groove is formed at the upper end of the connecting groove, and a sliding plate is slidably connected inside the guide groove. The locking post is fixed to the lower end of the corresponding sliding plate, and a spring is fixed to the upper end of the sliding plate. The spring is fixed to the upper end of the guide groove. The upper end of the fixing ring has evenly distributed connecting holes, and the locking post engages with the corresponding connecting hole. The fixing assembly is connected to all the locking posts. This connecting assembly facilitates the rapid connection of the wind turbine tower and the pipe pile.
[0006] Furthermore, the fixing component includes a rotating ring, a connecting block, a first arc-shaped clamping rod, and a second arc-shaped clamping rod. The rotating ring is rotatably connected to the upper end of the pipe pile surface. The upper end of the rotating ring is fixed with evenly distributed connecting blocks. The side of the connecting block is fixed with a first arc-shaped clamping rod and two corresponding second arc-shaped clamping rods. An arc-shaped hole is opened in the middle of the clamping post. The first arc-shaped clamping rod is engaged in the interior of the corresponding arc-shaped hole. Two corresponding arc-shaped grooves are opened on the surface of the clamping post. The second arc-shaped clamping rod is engaged in the interior of the corresponding arc-shaped groove. By setting the fixing component, all the clamping posts can be quickly fixed.
[0007] Furthermore, the fastening assembly includes a mounting ring and bolts. The lower end of the rotating ring is fixed with the mounting ring, which is fixed to the surface of the pipe pile by bolts. The fastening assembly is used to fix the rotating ring.
[0008] Furthermore, the guiding assembly includes a guide ring, a first ball bearing, and a second ball bearing. A first annular groove is formed at the upper end of the pipe pile, and a guide ring is disposed inside the first annular groove. The guide ring is fixed to the lower end of the wind turbine tower. Evenly distributed second ball bearings are disposed inside the first annular groove, with all second ball bearings respectively fitting against the inner wall and outer surface of the guide ring. Evenly distributed connecting grooves are provided at the lower end of the guide ring, and first ball bearings are rotatably connected inside the connecting grooves. All first ball bearings fit against the lower end of the first annular groove. This guiding assembly facilitates user rotation of the wind turbine tower.
[0009] Furthermore, a guide plate is fixed at the lower end of the wind turbine tower, and a limiting groove is provided at the upper end of the pipe pile. The guide plate is located inside the limiting groove, and the position of the wind turbine tower is limited by setting the guide plate.
[0010] Furthermore, a second annular groove is formed on the circumferential surface of the guide disc, and a deflecting ring is rotatably connected inside the second annular groove. The deflecting ring fits against the inner wall of the limiting groove set at the upper end of the pipe pile. The stability of the wind turbine tower rotation is improved by setting the deflecting ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The mounting structure for the wind turbine generator set has the following advantages: 1. The connection components enable rapid docking between the wind turbine tower and the pipe pile, effectively reducing the reliance on precise manual positioning during installation. This allows for more efficient hoisting operations in complex offshore environments, thereby shortening the installation window and improving overall construction efficiency.

[0019] The working principle of the wind turbine generator set mounting structure provided by this utility model is as follows: During the installation process, the wind turbine tower 1 is first hoisted above the pipe pile 2. The guide plate 7 is embedded into the limiting groove at the upper end of the pipe pile 2 for initial alignment, ensuring that the relative positions of the wind turbine tower 1 and the pipe pile 2 are basically stable. Subsequently, the guide assembly 6 begins to function. The guide ring 61 enters the first annular groove at the upper end of the pipe pile 2, and through the rolling action of the first ball 62 and the second ball 63, frictional resistance is reduced, allowing the wind turbine tower 1 to be finely rotated in the hoisted state. During the adjustment process, the locking column 3... 5. When the locking post 35 is aligned with the connecting hole, the spring 34 quickly releases its elastic force to push the locking post 35 into the connecting hole, completing the initial axial connection. When the wind turbine tower 1 is rotated to the appropriate position, the operator rotates the rotating ring 41, which drives the first arc-shaped locking rod 43 and the second arc-shaped locking rod 44 on the connecting block 42 to respectively engage in the arc-shaped hole in the middle of the locking post 35 and the arc-shaped locking groove on the surface, thereby achieving mechanical locking and preventing the locking post 35 from retracting. At the same time, the mounting ring 51 of the fastening component 5 is fixed to the surface of the pipe pile 2 by bolts 52, further reinforcing the position of the rotating ring 41 and ensuring a firm connection.
