Principle of New Vertical Axis Wind Turbine

This technology adopts the aerodynamic principle, and simulates the wind tunnel with vertical axis rotation. The blades are in the shape of aircraft wings, so that the efficiency of the wind wheel will not be affected by deformation when it rotates. It is composed of 4-5 vertically arranged blades, and the wind wheel is composed of a connecting rod fixed with a 4-angle or 5-angle hub and connected with the blades. The wind wheel drives the rare earth permanent magnet generator to generate electricity, which is sent to the controller to control and transmit the electric energy used by the load.

According to the gas strip theory and technical principle, the tangent plane perpendicular to the fan shaft can be selected for model calculation. According to the actual size of the blades, the distance between the rotating shafts of each blade is n meters. CFD technology is used to calculate the simulated aerodynamic coefficient, and discrete numerical method is used to solve the aerodynamic force of airfoil section. The grid method is used to compare the vortex distribution of Reynolds number flow, and the main results of numerical simulation calculation of Naville-Stokes equation at high Reynolds number are formed.

Based on the power generation principle of rare earth permanent magnet materials, coupled with the wind wheel with aerodynamic principle, the direct-drive structure is used for rotary power generation.

Patented technology: because this design structure adopts the mechanical principle of special air holes, the connection mode of triangular vector method and the principle of direct drive structure, the force of the wind wheel is mainly concentrated on the hub, which has strong wind resistance; The characteristics of this design are also reflected in the impact on the surrounding environment. The advantages of the new vertical axis wind turbine are very obvious because of its noiseless operation and small electromagnetic interference.

This type of vertical axis wind power generation system products are mostly produced in Japan (research began in 2002), and countries such as Britain and Canada are also under development. Most of the products in these countries use parallel connecting rods in the design of wind turbines, which have higher requirements for the output shaft of generators, relatively complex structures and too many on-site installation procedures. In addition, from the mechanical analysis, the greater the power, the longer the blades, the longer the distance between the center point of the parallel rod and the center point of the generator shaft, and the worse the wind resistance. Therefore, the triangular vector method can make up for some of the above shortcomings.
