Solution Overview
Problem
Current wind power generating devices face challenges in achieving stable operation and high power output due to increased weight and complexity, particularly with larger blades, which affect mechanical stability and installation difficulties.
Innovation Solution
The design incorporates two wind generating sets installed on a tower column, with one set near the top and another below, generating counteracting torques to enhance stability, along with a balancer and yawing system for directional control, and a vibration-absorbing foundation to improve mechanical stability and power output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the blade length is increased to improve wind power generating capacity, then the power output is improved, but the diameter and weight of the blade increase, making manufacturing and installation more difficult
Solution Approach 1:
The wind generating set is divided into multiple independent wind wheels (at least two), each with its own driving shaft and generator. This segmentation allows each wind wheel to have a smaller diameter and lighter weight while collectively achieving high power output, thereby reducing manufacturing and installation difficulties for individual components.
2Power
If multiple wind wheels are used to increase windward area and power output, then power generating efficiency is improved, but the mechanical stability of the frame deteriorates due to identical torques acting in the same direction
Solution Approach 1:
Adjacent wind wheels are arranged to rotate in opposite directions, creating asymmetric torque distribution. This causes the torques generated by multiple wind wheels to counterbalance each other, preventing identical torques from acting in the same direction on the frame, thereby maintaining mechanical stability while preserving power generating efficiency.
3Length of moving object
If multiple wind wheels co-drive one generator, then the diameter of wind wheels is reduced, but the requirement on generator capacity increases, increasing generator size and complicating nacelle arrangement
Solution Approach 1:
Each wind wheel is equipped with its own independent generator rather than co-driving a single generator. This segmentation allows each generator to be smaller in size and capacity, making nacelle arrangement and overall device layout more manageable while maintaining reduced wind wheel diameters.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for a super high power output while reducing manufacturing and installation complexities, enhancing mechanical stability and reliability, and enabling efficient use of high-level wind resources.
Implementation Method 1
The wind blows the wind wheels to rotate so that the kinetic energy of wind is transformed into mechanical energy
Implementation Method 2
each wind wheel drives a rotor of the generator to rotate by driving a driving shaft installed in the support rod and cuts the magnetic field of a stator to produce electrical current, thus transforming mechanical energy into electric energy
