[Prior Art] The use of wind energy has been used for thousands of years. In the early days, it was applied to agricultural irrigation and grinding of waste materials, and wind energy is a kind of self-produced energy that is never depleted and pollution-free. The principle of a wind turbine is to convert the wind into mechanical energy, which is then driven by mechanical energy to generate electricity. In general, wind turbines can be divided into horizontal axial wind turbines (Horizontal Axis Wind Turbine) and vertical axial wind turbines (Vertical Axis Wind Turbine) according to the relative position of the rotating main shaft and the horizontal plane. Among them, the vertical axial wind turbine itself does not need a steering device, but works by the wind resistance of the blade, or the blade is subjected to the lift of the wind, so that power generation can be performed without being affected by the wind direction. Please refer to Figure 1 for a schematic diagram of the structure of a general vertical axial wind turbine. The vertical axial wind turbine lanthanum includes a support rod 11, an impeller 2, and a power generating device 13, the support rod 11 is vertically disposed on the ground; the impeller 12 includes a plurality of shaft rings 121. And a plurality of support arms 122 are disposed on the periphery of the equiaxing ring 216, and a blade 123 is connected to the end of the corresponding branch arm 122 of each axis 珲i 2 i *, as shown in the figure. The middle of the shaft is connected to the top of the branch pole 11 in a paired manner. The power generating device 13 is disposed under the support rod to be in power communication with the impeller. When the impeller 12 is rotated by the wind, the mechanical energy of its rotation can drive the power generating device 13 to generate electric energy. However, the vertical axial wind turbine is the one that sighs the impeller. The top of the mysterious support bar i!, when the leaves # i 23 are subjected to wind: the resistance generated by the blow can not only drive the rotation of the impeller 12 but also generate electricity, which is not fixed due to the wind direction, plus the impeller 12 The centrifugal force and the force during rotation cause the rod 11 to sway; in addition, in order to increase the wind receiving effect, the height of the support rod u is increased, and the amplitude of the sway is relatively increased, which is more dangerous; When the impeller 12 is rotated by the wind, at the end edge of each blade 123 (as shown at A in FIG. 1), wind and wing tip turbulence may occur, which may cause noise during operation and wing tip turbulence. It is the main cause of the sway when the impeller 12 rotates, which affects the power generation efficiency. _ 疋 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , It is mounted on a specially designed bracket to completely avoid sloshing and noise during operation. [New content] 4 One of the purposes of this creation is to provide an impeller structure for a vertical axial wind turbine, using a silent wind cut + S3 · 曰 曰 承 ~ ~ · · mouth to reduce the damage caused by or wing turbulence Noise, increase the structure between the blades, the tamping plant "the quiet ring can also be transported... Γ At the same time avoid the sloshing problem caused by the wing tip turbulence and greatly improve the power generation efficiency.

In addition, the two sides of the mute % are planar; or the mute ring is semi-circular by the cross-sectional view and the mute ring is adjacent to the leaf month - the surface is The flat type 'the two types of silent ring can reduce the wind cut and the wing tip turbulence during the operation of the impeller, and the cross-sectional structure of the support arm and the cross-sectional structure of the blade The same 'can effectively cut the airflow and reduce the wind-cut phenomenon when the M393573 impeller rotates. In an embodiment, the wheel-hole bearing of the equi-axed ring has the function of increasing the impeller assembly when the shaft is connected to the shaft A low friction force to improve the efficiency of power generation. The degree of lubrication is reduced so that your review board can clearly understand the following descriptions. Please refer to the contents of & Please refer to Figures 2, 3 and 4. Schematic diagram of the three-dimensional structure of the v example, and its: Schematic diagram of the structure of the first-power generator, :::: a cross-sectional view of the vertical axial wind. As shown in the figure, the creation = ring and the impeller 20 of the blade motor are connected to the straight axial wind. The impeller 20 includes __ uranium #, ', on the shaft 31, u includes a pair of shaft rings 21, Fu Zhao phase # to the silent ring 23. A plurality of blades 22 and one of the shaft rings 21 And the circumference of the equiaxing ring 21 has eight-axis holes 2U, and the plurality of supporting arms 21 are provided with upper and lower pairs of the outer radiating portions: as shown in the figure, the shaft connecting rings 21 are as shown in the figure. The yoke is vertically symmetrical and is disposed on the shaft system (1) on the round rod-like structure 1, and the use of the support arms. The 卞 卞 is used to strengthen the connection of the blades - 轮承川#轮接% 21 In the sleeve hole, the impeller 20 w and the shaft 31 are sleeved with each other, and the lubrication degree when the # 20 f # 3i is set by the hammer 20 is reduced, and the friction force at the leaf rotation is reduced. Improve power generation efficiency. 6 M393573 «Hai blade 22 is arranged in a vertical manner, and the upper and lower ends of each blade 22 are respectively connected to the branch arms corresponding to the upper and lower two-axis rings 21 2 2 2 ancient * mountain teeth < Finally, the (four) direction of the θ 211 of the equiax ring 22 is parallelized. The pair of silent rings 23 are respectively connected to the top end and the bottom end of each of the blades 22, and the blades 22 are connected to the mute ring 23 in a body. It should be noted that both sides of the silent ring 23 are planar, and the width (1) of the silent ring 23 is greater than or equal to h5 times the thickness (T) of the blade 22 (as shown in FIG. 4, W-1.5T). In summary, when the wind drives the blade U of the impeller 2 to rotate, the belt will also drive the shaft ring 21 to rotate, and the airflow will be along the blades after being impacted by the blades > 22 upward or downward airflow cannot pass through the mute ring 23, reducing the wind cutting phenomenon at the ends of the blades 22 and avoiding the occurrence of wing tip turbulence to reduce noise; further, the mute ring 23 can be strengthened The strength and stability of the impeller 整体 can make the impeller 20 operate more to improve the power generation efficiency.
