Reconstruction Analysis of Vertical Shaft Type Windmill

    Vertical shaft type wind-power Chinese square-pallet chain-pumps is an important lost ancient machinery.
 This study extends the reconstruction research results of Vertical shaft type wind-power Chinese square-pallet chain-pumps, conducts reconstruction analysis, completes the record of Vertical shaft type wind-power process technologies and principles, and preserved the dying technique and craftsmanship.
 

    Reconstruction analysis of Vertical shaft type wind-power includes mechanism analysis,irrigation analysis, stress analysis, and structural analysis. Institutional analysis could bedivided into three systems:a propulsion system, a transmission system, and a pumping system.And then we could make mechanism and working principle analysis. By analyzing theirrigation performance based on the investigation of northern Jiangsu province rice irrigationmethods and wind observations, it shows in Yancheng City northern Jiangsu province area oneVertical shaft type wind-power Chinese square-pallet chain-pumps irrigates 66 acres offarmland. Stress analysis is to investigate the Vertical shaft type wind-power sail’s differentextreme positions under different actions of wind. When the first limit position is  = 18.06°and the second limit position is ! = 120.79°, the Vertical shaft type wind-power producemaximum work, then we can estimate torque and work produced by different wind speeds.Structural Analysis utilizes the SolidWorks software to design the 3D model and use ANSYS todo the strength analysis of the wind wheel structure, so it gets the the maximum stress andminimum safety factor’s occurrence of position in windmills’ framework of under 3-7 gradewind. The results of the reconstruction analysis in this study not only clarifies Vertical shafttype wind-power process technologies and principles but also provides an innovative referenceof Vertical axis wind turbine design.
