Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation bases, and more specifically, to a buffer structure of a wind power generation base. Background Art

[0002] During the operation of the existing wind power generation base, due to the influence of the foundation and the environment, large vibrations often occur. These vibrations not only affect the efficiency of the power generation equipment, but also may cause wear and damage to the equipment, thereby shortening its service life. In addition, the existing buffer structure often cannot effectively disperse and absorb vibration energy, resulting in unsatisfactory shock absorption effect and cannot meet the stable operation requirements of wind power generation equipment under complex working conditions.

[0003] Traditional buffer structures are usually simple in design and lack multi-point seismic protection, which makes the equipment prone to instability and damage under high-frequency vibration and strong wind environments. Especially in extreme weather conditions, the existing buffer structure cannot provide sufficient support and stability, which increases the maintenance and replacement costs of the equipment. Therefore, there is an urgent need for an improved wind turbine base buffer structure to improve the seismic resistance and service life of the equipment through a more effective shock absorption and stabilization mechanism.

[0024] It is necessary to further explain the above scheme that the buffer structure design of the wind power generation base is intended to improve the stability and earthquake resistance of the wind power generation equipment during operation. In practical applications, the structure firmly places the wind power generation device on top of a plurality of supporting upper bases 1 and supporting lower bases 2. These bases achieve effective support and earthquake resistance through the well-designed buffer structure.

[0025] First, the airbag-type buffer rubber pad 4 installed in the prefabricated hollow cavity 3 is in the form of two annular airbag-like structures, and the two airbags are connected to each other. The inner edge and the outer edge of the airbag-type buffer rubber pad 4 are respectively fixedly installed with a pre-embedded support plate 1 5 and a pre-embedded support plate 2 6. These components can provide additional balance and stability. At the edges of the supporting upper base 1 and the supporting lower base 2, a pre-embedded support plate 3 7 is fixedly installed. These components are used to clamp the airbag-type buffer rubber pad 4, the pre-embedded support plate 1 5 and the pre-embedded support plate 2 6 to ensure that the airbag remains in position during the vibration process;

[0026] In addition, at the positions of the two embedded support plates 3 7 between the support type upper base 1 and the support type lower base 2, a helical sheet coil spring 8 for buffering is installed, and the outer edge of the buffer component is fixedly installed with an external frame groove 9, which is arranged in a one-to-one correspondence. The outer edge of the embedded support plate 3 7 is also fixedly installed with a limiting clamp ring 10, and the limiting device is attached to the surface of the support type upper base 1 or the support type lower base 2, further enhancing the stability of the overall structure;
