[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a wind turbine ring beam fixing device, such as Figures 1-4 As shown, it includes a support beam 1, a main machine 2 is installed on the top of the support beam 1, a pillar 3 is installed on the bottom of the support beam 1, and the support beam 1 includes a plurality of arc-shaped plates 11. The plurality of arc-shaped plates 11 together form a ring structure. A grouting cavity 111 is provided inside each arc-shaped plate 11, and a plurality of grouting holes 112 connected to the grouting cavity 111 are opened on the outer side surface of the arc-shaped plate 11. A protrusion 113 is provided at the end of each arc-shaped plate 11, and the protrusions 113 on two adjacent arc-shaped plates 11 are fixed by connecting bolts 1131.

[0028] During use, a support beam 1 with an annular structure is formed by combining several curved plates 11. The support beam 1 is placed horizontally, thereby achieving stable support for the main unit 2. This design not only simplifies the installation process and improves installation efficiency, but also allows for on-site grouting reinforcement through the grouting cavity 111 set inside the curved plate 11 and the grouting hole 112 on the top, further enhancing the structural strength and stability of the support beam 1. At the same time, the protrusion 113 design at the end of the curved plate 11, used in conjunction with the connecting bolts 1131, ensures a tight connection between the several curved plates 11, forming a stable and reliable annular support structure. This structure can not only effectively withstand and disperse wind loads, but also improve the durability and fatigue resistance of the entire fixture, providing a strong guarantee for the long-term stable operation of the wind turbine.

[0029] In this embodiment, an inner washer 12 is installed on the inner side of the support beam 1, and an outer washer 13 is installed on the outer side of the support beam 1. This design effectively enhances the isolation and protection of the support beam 1 from the surrounding structure. The inner washer 12 prevents direct contact between the inner side of the support beam 1 and the main unit 2 or other internal components, reducing wear and corrosion. The outer washer 13 protects the support beam 1 from external environmental factors such as wind, rain, and corrosion, while also providing a certain degree of cushioning, extending the service life of the support beam 1 and improving the stability and durability of the entire fixture.

[0030] Specifically, a locking bolt 114 is mounted on a protrusion 113 on one end of each curved plate 11, which is used to securely lock one end of the curved plate 11 to the bottom of the main unit 2. This design ensures a tight connection between the curved plate 11 and the main unit 2, prevents structural instability caused by loosening or displacement, and improves the safety and reliability of the entire fixing device.

[0031] Furthermore, a protrusion 113 on one end of the curved plate 11 is secured to the mainframe 2 via a locking bolt 114, achieving a secure connection between the support beam 1 and the mainframe 2. This connection method is not only simple and easy to implement, but also ensures that the support beam 1 provides stable support for the mainframe 2, maintaining structural stability and safety even in extreme wind conditions.

[0032] Furthermore, a buffer assembly 14 is mounted on the curved plate 11, outside the protrusion 113. This provides additional cushioning and shock absorption for the entire fixture. When the wind turbine is subjected to wind loads or dynamic loads, the buffer assembly 14 absorbs and disperses some of the load, reducing the impact on the support beam 1 and main unit 2, thereby extending their service life and improving the operational stability and reliability of the entire wind turbine.

[0033] Furthermore, the buffer assembly 14 includes a round rod 141, and the end face of the projection 113 is provided with a receiving groove. One end of the round rod 141 is installed with a fixed plate 142. The outside of the round rod 141 is provided with a spring 143. The outer wall of the fixed plate 142 is connected to the inner wall of one side of the receiving groove on the projection 113. One end of the spring 143 is fixedly connected to the fixed plate 142, and the other end can abut against the end face of another adjacent projection 113. This structural design makes the buffer assembly 14 have good elasticity and resilience. When the external wind blows towards the main unit 2 and the load force received by the main unit 2 is transmitted to the support beam 1, the gap position between the two adjacent projections 113 undergoes slight deformation. The spring 143 can deform to absorb energy and transfer the load to the projection 113 through the round rod 141 and the fixed plate 142, thereby achieving effective buffering and dispersion of the load. This structure not only improves the buffering effect, but also is easy to maintain and replace.

[0034] Furthermore, the multiple grouting holes 112 on each curved plate 11 are arranged in a circular pattern with equal spacing. This design ensures that the grouting material is evenly injected into the grouting cavity 111 during grouting, thereby improving the reinforcement effect of the grouting. Furthermore, the equally spaced grouting holes 112 also make the grouting process simpler and faster, reducing construction difficulty and cost.

[0035] Furthermore, a support plate 31 is mounted on the top of the support column 3, which is bolted to the bottom of the support beam 1. This design ensures a secure connection between the support column 3 and the support beam 1. This bolted connection is not only simple and reliable, but also easy to adjust and remove, facilitating on-site installation and maintenance. Furthermore, the design of the support plate 31 enhances the support provided by the support column 3 to the support beam 1, improving the stability and safety of the entire fixture.

[0036] When using the wind turbine ring beam fixture of the present invention, the core component is the support beam 1, which is composed of a plurality of curved plates 11 forming a ring-shaped structure. This design not only facilitates on-site installation and disassembly, but also, through the combination of the curved plates 11, can accommodate the support requirements of wind turbine mainframes 2 of varying sizes. An inner gasket 12 and an outer gasket 13 are installed on the inner and outer sides of the support beam 1, respectively, ensuring a tight seal at the gap and resisting erosion from external environmental factors, providing additional protection and cushioning for the entire fixture.

[0037] Next, the ends of the curved plates 11 are provided with bumps 113. These bumps 113 on the two curved plates 11 are secured together by connecting bolts 1131, ensuring a tight connection between the two curved plates 11 and forming a stable and reliable annular support structure. Furthermore, locking bolts 114 are mounted on the bumps 113 to securely fasten one end of the curved plate 11 to the main unit 2. This dual securing mechanism further enhances the safety and reliability of the entire fixture.

[0038] A buffer assembly 14 is mounted outside the protrusion 113 on the curved plate 11. It comprises a round rod 141, a fixing plate 142, and a spring 143. When the wind turbine is subjected to wind loads or dynamic loads, the buffer assembly 14 absorbs some of the load, reducing the impact on the support beam 1 and main unit 2, thereby extending their service life and improving the operational stability and reliability of the entire wind turbine.

[0039] In addition, after installation is completed, grouting material can be injected into the grouting cavity 111 through the grouting holes 112 to perform grouting reinforcement, further enhancing the structural strength and stability of the support beam 1. During the grouting process, the grouting holes 112 are arranged at equal intervals to ensure that the grouting material is evenly distributed, thereby improving the grouting reinforcement effect.

[0040] Finally, the design of the support plate 31 also enhances the supporting effect of the pillar 3 on the support beam 1, thereby improving the stability and safety of the entire fixing device.
