Abstract
Description
Technical Field
[0001] This application relates to the technical field of tower strong wind resistance for wind power generation equipment, and particularly to a strong wind resistant flange gasket for a wind power tower. Background Art
[0002] As an important part of clean energy, wind power generation has achieved rapid development in recent years. The wind power tower, as a key structure in the wind power generation system, its stability and safety directly affect the operation efficiency and lifespan of the entire power generation system. In order to ensure the stability of the tower in the face of extreme weather conditions such as strong winds, numerous researchers and enterprises have invested a large amount of resources in developing related technologies, continuously exploring new design concepts and technical means to be able to more efficiently cope with the challenges brought by strong winds, thereby ensuring the normal operation of the wind power generation system.
[0003] In the design of wind power towers, common wind resistance measures mainly include strengthening the strength of the tower structure itself and adopting a dynamically adjustable structural design to ensure the stability of the tower under strong winds. Existing technical means mainly include fixed measures such as thickening the tower and adding truss structures, as well as dynamically adapting to wind changes by designing a cable system with adjustable tension. In addition, a variety of sensors and control systems are also applied to adjust the tower posture or reinforcement measures in real-time by monitoring wind speed and direction changes to improve the wind resistance performance. These solutions have, to a certain extent, solved the impact of strong winds on the tower, and significantly improved the safety performance of wind power towers by enhancing structural stability and dynamic adjustment.
[0004] However, there are some deficiencies in the above technical means in practical applications. For example, thickening the tower structure will significantly increase the overall weight of the tower, resulting in an increase in manufacturing costs and also increasing the difficulty of installation and maintenance; while the dynamically adjustable cable system can effectively reduce the impact of wind on the tower, but the fixing method between the ropes and the tower body is mostly traditional knotting, which has a risk of fixing failure during implementation.
