The technical solution of the above embodiment of the present invention is described in detail using several specific embodiments below.
Embodiment one
Fig. 1 is the structural schematic diagram of wind power generation plant embodiment one of the present invention, as shown in Figure 1, the device of the present embodiment
May include：
First conducting element 11, the second conducting element 12 and flexible friction layer 13, the flexible friction layer 13 are located at described
Between first conducting element 11 and second conducting element 12, first conducting element 11 and second conducting element 12
It is arranged to angle.For example, in the present embodiment, the first conducting element 11 and the second conducting element 12 can have conduction
The layer structure of property.One end of first conducting element 11 and the second conducting element 12 is fixed, the other end can according to air force,
The angle for adjusting the first conducting element 11 and the second conducting element 12, to promote the applicability of wind power generation plant.
As shown in Figure 1, there is first conducting element 11 first rubbing surface 110, second conducting element 12 to have
Second rubbing surface 120.For example the first rubbing surface 110 and the second rubbing surface 120 can be attached or directly be prepared first
On the surface of conducting element 11 and the second conducting element 12.The flexible friction layer 13 is led with described first under the action of the forces of the wind
First rubbing surface 110 of electric device 11 and/or the second rubbing surface 120 of second conducting element 12 are contacting and separating to generate
Induced current, and induced current is exported by the first conducting element 11 and the second conducting element 12 outward.The wind of the present embodiment
Power generation device is that mechanical energy is converted to electric energy in nanometer range, has small advantage.
In the present embodiment, the first rubbing surface 110 and second that flexible friction layer 13 is set to the first conducting element 11 is conductive
Between second rubbing surface 120 of element 12；First conducting element 11 and second conducting element 12 are arranged to angle；Institute
Flexible friction layer 13 is stated to contact and divide with first rubbing surface 110 and/or second rubbing surface 120 under the action of the forces of the wind
From to generate induced current；Induced current is exported outward by first conducting element 11 and second conducting element 12.
The wind power generation plant drives the first rubbing surface 110 or the of flexible friction layer 13 and the first conducting element 11 using the kinetic energy of wind
Second rubbing surface 120 of two conducting elements 12 is in contact and detaches, and generates induced current and then exports to form electric current outward, will
Mechanical energy is converted into electric energy.Since flexible friction layer 13 is set to the folder that the first conducting element 11 and the second conducting element 12 are formed
In angle, flexible friction layer 13 can be led with the first rubbing surface 110 of the first conducting element 11 and/or second under the action of the forces of the wind

The bulk of wind power generation plant.
One end of first conducting element 11 and the second conducting element 12 can be relatively fixed.The one of flexible friction layer 13 in this way
End can be fixed between the first conducting element 11 and the second conducting element 12, and the other end of flexible friction layer 13 can be with wind-force
Under the action of with the first rubbing surface 110 of the first conducting element 11 and/or the second rubbing surface 120 of second conducting element 12
It is contacting and separating to generate induced current.The other end of first conducting element 11 and the second conducting element 12 can be freely adjusted to
Certain angle, to provide the space being contacting and separating for flexible friction layer 13.Since the first conducting element 11 and second is conductive
When 12 angle of element is more than 180 degree, the first rubbing surface 110 of flexible friction layer 13 and the first conducting element 11 and/or the
Second rubbing surface 120 of two conducting elements 12 can not fully be contacting and separating to generate induced current, therefore usual first
Conducting element 11 and 12 angle of the second conducting element should be less than 180 degree.For example, in the present embodiment, soft in order to make
Frottage layer 13 is filled with the first rubbing surface 110 of the first conducting element 11 and/or the second rubbing surface 120 of the second conducting element 12
It is contacting and separating with dividing, can be set the first conducting element 11 and 12 angle of the second conducting element according to the power of wind-force
It is set to 5 degree of -90 degree.
Wind power generation device structure in the present embodiment is simple, and energy conversion efficiency is high, has application scenarios widely excellent
Point.
Embodiment two
The present embodiment is the comparative example of embodiment one.Fig. 2 is the structure of wind power generation plant embodiment two of the present invention
Diagrammatic cross-section.As shown in Fig. 2, the wind power generation plant of the present embodiment is on the basis of embodiment one, by the first conducting element
It is provided parallel to the second conducting element.

Capable measured value.It can see that the rectified current flow of (30 °) generations of inner clip corner structure at the same time is 3.5 μ A from figure,
It is 5 times of the 0.7 μ A of rectified current flow that parallel construction generates.Voltage also to being generated to above two wind power generation plant simultaneously
(as shown in Figure 4) is measured, the voltage value for also obtaining angle structure (30 °) is 5 times of parallel construction voltage value.
The reason of causing this species diversity is that angle structure makes flexible friction layer that can rub under the action of the forces of the wind with first
Wiping face and the second rubbing surface more fully contact.And in parallel construction, flexible friction layer can not be connect with partial frictional face
