Description

Technical Field

[0002] With its huge reserves, wide distribution, and clean and pollution-free characteristics, offshore wind energy has become an important option for addressing the global energy crisis and environmental challenges. In recent years, with the gradual development of onshore wind power resources, offshore wind power has rapidly expanded its installed capacity due to its advantages such as stable wind speed and small wind shear, and has gradually become the focus of development in the wind power field.

[0003] As the basic support structure of offshore wind power generation systems, the performance and installation efficiency of offshore wind turbine piles directly affect the construction cost, operational stability and service life of the entire power generation system; in actual offshore wind turbine pile installation operations, traditional technologies face many challenges.

[0004] Traditional wind turbine pile structures are complex in design and cumbersome in their component connections. Typically, dozens of bolts are used to secure adjacent components, and precise positioning is required during connection. Due to the complex marine environment, precise positioning is often difficult to achieve. This not only leads to low production efficiency during the prefabrication stage but also results in complex installation processes and high construction difficulty at sea, demanding extremely high levels of technical skill and operational experience from construction personnel, further reducing installation efficiency and increasing construction risks. Therefore, we propose a simplified structure for easy installation of offshore wind turbine piles. Utility Model Content

[0028] Please see Figures 1-4 This utility model provides a technical solution: a simple structure for easy installation of marine wind turbine piles, including a support platform 10 and multiple base columns 1 fixedly installed on the bottom surface of the support platform 10. The number of base columns 1 is 2 to 4. The cross section of the support platform 10 is cross-shaped. This layout effectively distributes the weight of the upper structure, improves stability in complex marine environments, ensures the overall stability of the wind turbine pile, realizes stable support operation of the support platform 10, and provides a stable support foundation for the entire structure.

[0029] Specifically, a central hole 11 is provided at the center of the support platform 10, and a wind turbine pile 2 is inserted into the central hole 11 to enable the wind turbine pile 2 to be quickly and initially positioned. The front corner 12 of the support platform 10 is provided with a first corner hole 121 that communicates with the central hole 11. A second corner hole 13 that communicates with the outside is provided on the rear wall of the central hole 11. An upper limit insertion hole 14 that communicates with the second corner hole 13 is provided on the top surface of the rear plate of the support platform 10. A horizontal insertion hole 20 is provided on the bottom column of the wind turbine pile 2. A horizontal limiting plate 22 is inserted into the first corner hole 121, the second corner hole 13 and the insertion hole 20. This design realizes the precise horizontal positioning of the wind turbine pile 2 on the support platform 10, which greatly simplifies the positioning process during installation and improves installation efficiency.

[0030] Specifically, an end limiting plate 23 is fixedly installed at the front end of the horizontal limiting plate 22, which abuts against the corner portion 12. The size of the end limiting plate 23 is larger than the size of the first corner hole 121, effectively preventing the horizontal limiting plate 22 from being over-inserted. A support plate 15 is fixedly installed on the side of the front corner portion 12. The support plate 15 is located below the first corner hole 121. The support plate 15 provides auxiliary support for the end limiting plate 23, reducing the stress on the horizontal limiting plate 22 and related components, and improving the structural durability.

[0031] In this embodiment, a rectangular hole 24 is provided on the rear side plate of the horizontal limiting plate 22. A plug-in block 25 is inserted into the rectangular hole 24 and the upper limit insertion hole 14. The cross-section of the plug-in block 25 is a right trapezoid. A top plate 251 is fixedly installed on the top of the plug-in block 25. The plug-in block 25 abuts against the hole wall of the rectangular hole 24. A coarse stud 26 is fixedly installed at the bottom of the plug-in block 25. A fastening nut 27 is threaded onto the coarse stud 26, so that the plug-in block 25 abuts against the hole wall of the rectangular hole 24. The coarse stud 26 is connected to the bottom of the plug-in block 25 and fixed by the fastening nut 27. This achieves reliable fixation of the wind turbine pile 2 in the vertical direction, avoids the pile from loosening, and improves the overall structural stability.

[0032] Specifically, the cross-sections of the corner portion 12, the first corner hole 121, the second corner hole 13, and the insertion hole 20 are all L-shaped. The dimensions of the horizontal limiting plate 22 are adapted to the dimensions of the first corner hole 121, the second corner hole 13, and the insertion hole 20 to stabilize the assembly operation.

[0033] Furthermore, a support plate 21 is fixedly installed on the bottom column of the wind turbine pile 2. The support plate 21 rests against the upper surface of the support platform 10, increasing the contact area between the wind turbine pile 2 and the support platform 10. Multiple support ribs 211 arranged in a ring at equal intervals are fixedly installed between the upper surface of the support plate 21 and the wind turbine pile 2. The number of support ribs 211 is between 4 and 12, which further enhances the structural strength of the bottom of the wind turbine pile 2 and effectively improves the stability of the entire wind turbine pile structure.

[0034] In addition, an elastic washer 261 is fitted on the stud 26, and the fastening nut 27 presses the elastic washer 261 against the bottom surface of the support platform 10. By using the fastening nut 27 to press the elastic washer 261 against the bottom surface of the support platform 10, the wear between the fastening nut 27 and the support platform 10 is reduced, and the fastening nut 27 is prevented from loosening, thus extending the service life of the structure and reducing maintenance costs.

[0035] When using the simplified structure of the conveniently installed offshore wind turbine pile of this utility model, after the base column 1 and support platform 10 are transported to the designated sea area installation location and fixed, the wind turbine pile 2 with support plate 21 and support rib 211 at the bottom is initially positioned by inserting it into the center hole 11 of the support platform 10; then, the horizontal limiting plate 22 is inserted into the first corner hole 121, the second corner hole 13 and the insertion hole 20 at the bottom of the wind turbine pile 2 in sequence to achieve precise horizontal positioning of the wind turbine pile 2 on the support platform 10, preventing the wind turbine pile 2 from rotating and moving in the vertical direction. The end limiting plate 23 abuts against the corner 12 to prevent the horizontal limiting plate 22 from being over-inserted, and the support plate 15 provides auxiliary support for the end limiting plate 23.

[0036] Next, insert the right-angled trapezoidal plug 25 into the rectangular hole 24 of the horizontal limiting plate 22 and the upper limit insertion hole 14 of the support platform 10. As the plug 25 is continuously pressed down and inserted, the horizontal limiting plate 22 can be pressed tightly in the horizontal direction to ensure that the plug 25 is tightly against the wall of the rectangular hole 24. Then, the elastic washer 261 is put on the coarse stud 26, and finally the fastening nut 27 is tightened to complete the vertical fixation of the wind turbine pile 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
