Embodiment 1

[0056] A kind of vertical axis wind power generation unit with multi-layer spread wings and double swing blades of the present invention, such as figure 1 and figure 2 As shown, it includes a generator 17, two layers of wind wheels and a frame mechanism. The two layers of wind wheels are sequentially installed on the frame mechanism from bottom to top, and the frame mechanism is driven and connected with the vertical shaft of the generator 17. Set on the fixed column 15, the frame mechanism includes a rotating sleeve 18, a bearing 16, an upper frame 13 and a lower frame 19 installed on the vertical shaft of the generator 17, and the upper end of the rotating sleeve 18 is fixed on the The vertical axis of the generator 17, the lower end of the rotating casing 18 is rotatably mounted on the fixed column 15 through a set of bearings 16, the upper frame 13 is fixed on the upper end of the rotating casing 18, and the lower frame 19 is fixed on the The lower end of the sleeve 18 i...

Embodiment 2

[0074] A vertical axis wind power generator set with multi-layer spread wings and double swing blades of the present invention is basically the same as that of Embodiment 1, the difference is that in this embodiment, the upper pressing roller and the lower pressing roller are respectively arranged to be rotatable around their own central axes in the pole 9. There is sliding friction between the guiding mechanism 6 arranged in this way and the steel rope, and the resistance is small.

[0075] The main technical solution of this embodiment is basically the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

Embodiment 3

[0077] On the basis of Embodiment 1, the vertical axis wind power generating unit with multi-layer wings and double swing blades of the present invention, in this embodiment, the strut 9 is provided with a hinged seat 11, and the plane where the hinged seat 11 is located is on the same plane as the strut 9. The surface is arranged vertically, and the hinged seat 11 of the strut 9 is rotatably connected to the frame mechanism through the second pin shaft 4 . In this embodiment, the hinged seat 11 is arranged in a triangular shape, and one end of the hinged seat 11 assembled with the second pin 4 is rounded. It should be noted that the hinge seat 11 of the present invention can be not only triangular, but also can be set in other shapes, such as semicircle, rectangle, polygon, as long as it can be provided with an opening through which the first pin shaft 12 penetrates and connects with Described strut 9 is fixedly connected and gets final product. The pole 9 of the present inv...

Abstract

A vertical-axis wind power generating set with multi-layer spread wings and double swing blades includes a generator, at least two layers of wind wheels and a frame mechanism, and the at least two layers of wind wheels are sequentially installed on the frame mechanism from bottom to top. The wind pressure of the multi-layer wind wheel of the present invention is continuously balanced, and the torque of the wind wheel is transmitted to the generator through the frame mechanism, so that the utilization rate of wind energy is high and the generating capacity is large. The fan blade and the support rod use the first pin shaft, compression spring, and steel wire rope to keep the upper blade and the lower blade in a vertical state within the rated wind speed range to obtain the largest windward area. When encountering strong wind, the wind wheel rotates quickly , as the speed of the wind rotor increases, the upper blade and the lower blade form an angle with the pole through the wire rope compression spring, and the rotation shape of the entire wind blade becomes V-shaped, thereby changing the windward area of ​​the wind rotor group and achieving the adjustment of the whole machine. For the purpose of power output, it has the advantages of stable operation, simple structure, wide range of suitable wind speed, high utilization rate of wind energy and long service life of the generator.

Description

technical field [0001] The invention relates to the technical field of vertical-axis wind power generators, in particular to a vertical-axis wind power generator with multi-layer spread wings and double swing blades. Background technique [0002] In the prior art, there are two main types of vertical-axis wind turbines: one is a lift-type fan that utilizes the lift of the airfoil structure to do work, and its prototype is a Darrieus-type wind turbine. The manufacture of most vertical-axis wind turbines The technology is based on the operation principle of the airfoil structure with a little improvement. The vertical axis lift fan can use up to 42% of the wind energy during normal operation; the other is the resistance fan, whose prototype is the wind cup type The wind measuring instrument evolved, and its principle is to use the resistance difference between the front and the back of the wind blade to do work when it rotates horizontally. [0003] Vertical axis wind turbine...
