Description

Technical Field

[0001] This utility model relates to the field of wind power construction technology, specifically to a construction platform for wind turbine towers. Background Technology

[0002] The wind turbine tower, the connecting component between the wind turbine and the foundation ring, bears the weight of the hundreds of tons of wind turbine above and is a crucial component for wind turbine maintenance, power transmission, and other functions. The domestic wind turbine tower industry possesses strong global competitiveness due to its significant advantages in raw material supply and cost. The hybrid tower solution has rapidly captured the market primarily because it meets the development needs of the wind power industry—higher and more economical. As wind power development enters the era of grid parity, larger wind turbines have become the mainstream trend. The tower is no longer just responsible for supporting the wind turbine but has become an important device for enhancing wind energy harvesting capabilities. Generally, the higher the tower, the more wind the wind turbine captures. Simultaneously, the larger size of the turbine means longer blades, which also places demands on the tower's height. Hybrid towers are typically composed of a combination of materials such as concrete and steel. The concrete provides excellent compressive strength, while the steel effectively resists tensile forces, preventing excessive deformation. This synergistic work of concrete and steel allows hybrid towers to maintain good mechanical properties when subjected to complex load combinations, enabling them to be built even taller. In the era of grid parity for wind power, the more economical tower type is undoubtedly more popular in the market.

[0003] Industry data shows that for towers over 140 meters in height, the cost of hybrid towers is only 60%-70% of that of steel grating towers of the same height, and the cost advantage of hybrid grating towers is expected to further increase with the increase in tower height. Meanwhile, since the concrete construction of hybrid towers is carried out near the project site, significant transportation costs are saved. With the widespread deployment of wind turbines using hybrid tower solutions, the characteristics of high-altitude operations, diameter changes, and high wind speeds at high altitudes present challenges for defect repair, inspection, and maintenance. A work platform that can be easily assembled manually at high altitudes is needed to complete these tasks, thus requiring a construction platform for wind turbine towers. Utility Model Content
