Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind power generator sets face challenges in increasing the bearing capacity of tower tubes without significantly increasing material usage and costs, which hinders the development of larger megawatt-level systems.
Innovation Solution
A tower tube section design incorporating a reinforcing assembly with supporting members and circumferentially spaced reinforcing cables that extend axially, allowing for improved load distribution without altering the original structure of the tower tube section body, thus enhancing bearing capacity while maintaining low costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wall thickness of each tower tube section is increased to improve bearing capacity, then the strength of the tower tube section is improved, but the material used and cost are increased
Solution Approach 1:
The patent applies composite material principles by combining the tower tube section body with a reinforcing assembly consisting of supporting members and reinforcing cables. This composite structure allows the tower tube to achieve higher bearing capacity without increasing the wall thickness of the tube body, thereby reducing material consumption while improving strength
Solution Approach 2:
The reinforcing assembly is segmented into multiple components: supporting members and multiple reinforcing cables arranged at intervals. This segmentation allows the load to be distributed across multiple discrete elements rather than requiring uniform thickening of the entire tube wall, optimizing material usage
2Strength
If the radial size of the tower tube section is increased to improve bearing capacity, then the strength of the tower tube section is improved, but the material used and cost are increased
Solution Approach 1:
Instead of increasing the radial size of the tower tube section, the patent introduces reinforcing elements along the axial direction and circumferential distribution. The reinforcing cables extend along the axial direction and are spaced at intervals in the circumferential direction, utilizing additional spatial dimensions to enhance bearing capacity without increasing the tube's radial footprint or material volume
3Strength
If the tower tube section structure is modified to improve bearing capacity, then the strength is improved, but the processing difficulty and cost are increased
Solution Approach 1:
The tower tube section is divided into separable components: the original tower tube section body and the reinforcing assembly. The reinforcing assembly itself is segmented into supporting members and reinforcing cables. This segmentation allows each component to be manufactured independently using standard processes, then assembled together, avoiding the need for complex integrated manufacturing and reducing processing difficulty
Solution Approach 2:
The supporting members act as intermediaries that connect the tower tube section body to the reinforcing cables. This intermediary structure simplifies the connection process, allowing the reinforcing cables to be attached to the supporting members rather than directly to the tube body, thereby reducing processing complexity

AI summary
The present application relates to a tower tube section, a tower frame and a wind power generator set. The tower tube section includes a tower tube section body; a reinforcing assembly including a supporting member connected to the tower tube section body and a plurality of reinforcing cables connected to the supporting member. The plurality of reinforcing cables are arranged at intervals along a circumferential direction of the tower tube section body, and each of the plurality of reinforcing cables extends along an axial direction of the tower tube section body and is apart from a periphery surface of the tower tube section body by a predetermined distance in a radial direction of the tower tube section body. The tower tube section has a strong bearing capacity and low cost, which can meet the power generation benefits of the wind power generator set.
