Problems solved by technology

[0004] In order to overcome the problems of existing small vertical axis wind turbines such as complex structure, poor mechanical transmission efficiency, and low power generation efficiency, the present invention provides a small vertical axis wind turbine, which is a high-efficiency wind turbine with low speed and low noise. The wind power generator for power generation can not only automatically limit the speed when the wind speed is high, but also has a safe lightning protection mechanism and braking mechanism

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the support frame 5 is wheel-shaped and placed horizontally on the vertical tower 6, the top of the support frame 5 is placed vertically with the lightning rod 1, the stator 4 is horizontally placed on the support frame 5, and the outer rotor 3 can only wind around It rotates horizontally; the blade 2 is an airfoil blade, hinged with the outer rotor 3, and the hinge is directly above the center of gravity of the blade 3, and the blade 3 can swing around the hinge axis in the vertical plane.

[0019] Such as figure 2 As shown, a horizontal annular brake drum 7 is fixed on the lower part of the outer rotor 3. The brake drum 7 can also be integrated in the outer rotor 3, and the brake shoe 8 corresponding to the brake drum 7 is fixed on the slider 10. The slide block 10 is placed on the guide rail 9 fixed on the lower p...

Abstract

The invention discloses a small-sized efficient vertical axis wind turbine which comprises a tower frame, wherein the upper part of the tower frame is provided with a support frame; a wind power generating device is installed on the support frame, and a lightning-protection device is also arranged on the support frame; and meanwhile, a brake device is also installed between the wind power generating device and the support frame. The invention has convenient installation, is economic, attractive and safe and prevents lightning without noise, wire twisting phenomenon and scintillation effect and is quite suitable for being used on a roof of a building with high population density.

Description

technical field [0001] The present invention relates to a vertical-axis wind power generator, in particular to a small-scale high-efficiency vertical-axis wind power generator, which is mainly used in cities or residential areas with abundant wind resources. Background technique [0002] Because it is generally believed that the utilization rate of wind energy of vertical axis wind turbines is lower than that of horizontal axis, vertical axis wind turbines have not been paid much attention for a long time. With the development of lift-type wind blades, the wind energy utilization rate of the vertical axis wind turbine is no longer lower than that of the horizontal axis, and compared with the horizontal axis wind turbine, it has the advantages of convenient maintenance, simple design and manufacture of wind blades, and low cost. The advantages of no wind-facing device, low noise, and low flicker effect on human eyes make it possible for vertical axis wind turbines to be used ...
