For being fully understood by purpose, feature and effect of the present invention, by following specific embodiments, the present invention is done in detail
Describe in detail bright, but the present invention is not restricted to this.
The invention discloses a kind of wind power generation plant and wind generator system, send out in order to solve wind-force of the prior art
Electric installation complex structure, problem with high costs.
Fig. 1 a shows the external structure schematic diagram of the wind power generation plant that the present invention provides, and Fig. 1 b shows that the present invention carries
For wind power generation plant internal view.Reference picture 1a to Fig. 1 b can be seen that this wind power generation plant and includes: support tube
11st, power transmission shaft 12, at least one wind-driven part 13 and by rubbing that first electrode layer 141 and the second electrode lay 142 are constituted
Wipe electromotor.
Wherein, support tube 11 can be pillar support cylinder, for example, it is possible to be cylindrical support cylinder or prismatic support tube
Deng.When support tube is for prismatic support tube, can be the various shapes such as four prism type, hexagon.And, support tube also may be used
Think the other shapes such as pyramid type, the present invention is not construed as limiting to this.In addition, the material of support tube 11 preferably has Mechanics of Machinery propping up
The material of support performance, for example, high molecule plastic, rustless steel, glass, pottery or alloy type material etc..Power transmission shaft 12 is located at and supports
The inside of cylinder 11 is it is preferable that power transmission shaft 12 is located at the central axis of support tube 11, and the top of power transmission shaft 12 is from support tube 11
Inside stretch out.The material of power transmission shaft can be metal, macromolecular material that is ceramic or wear-resisting and having mechanical strength etc..Specifically
When realizing, support tube is relatively fixed with the position of power transmission shaft, and power transmission shaft can rotate with respect to support tube.In order to realize this
Point, support tube 11 can have a cylinder or prismatic side wall, have a diapire simultaneously, by power transmission shaft and this diapire
Centre be flexibly connected, so that power transmission shaft can be rotated with respect to support tube；Or it is also possible to make support tube only have side wall not have
There is diapire, the bottom of side wall is fixed on a fixed position, meanwhile, fix a bottom at the central axis of support tube
Seat, power transmission shaft inserts in this base and can rotate freely in base, thus power transmission shaft can rotate with respect to support tube.This
In invention, the concrete fixed form between support tube and power transmission shaft is not limited, as long as being capable of power transmission shaft with respect to support
The purpose of cylinder rotation.
Wind-driven part 13 is mainly used in driving above-mentioned power transmission shaft to rotate.Specifically, the of wind-driven part 13
One end is the fixing end being installed in power transmission shaft 12 top, and the second end of wind-driven part 13 is can to drive under wind-force effect
The free end that power transmission shaft 12 rotates with respect to support tube 11.For example, the free end of this wind-driven part can pass through fan
The modes such as one blade of one flabellum, a cup piece of vane or fan blade are realizing.Correspondingly, this wind-driven part from
Can be the various shapes such as sector, rectangle, circle or arc by the shape held, in the present invention, its concrete shape not limited
Fixed, as long as the shape being suitable for collecting wind energy all can adopt.In addition, in order to improve the efficiency collecting wind energy, thus promoting power transmission shaft
Quickly rotate, the quantity of wind-driven part 13 can be multiple, at this moment, between two often adjacent wind-driven parts
Angle is preferably equal.In addition, for the ease of the above-mentioned one or more wind-driven parts of fixation, can also consolidate on power transmission shaft
If a sleeve, wind-driven part is fixed on power transmission shaft by sleeve.
Under the drive of wind-driven part, as long as blowing air over, power transmission shaft will rotate with respect to support tube.Accordingly
Friction generator is divided into two parts that are separate and contacting with each other in the present invention, a part is arranged on power transmission shaft, separately by ground
A part is arranged on support tube, so, when blowing air over, is arranged on this partial frictional electromotor on power transmission shaft with biography
Moving axis is rotated, and is arranged on this partial frictional electromotor then remains stationary on support tube, therefore, therebetween will
Meeting constantly phase mutual friction, thus produce electric energy.
Lower mask body introduces above-mentioned two parts of friction generator.As shown in Figure 1 b, in friction generator
It is divided into the first electrode layer 141 on power transmission shaft, another part is the second electrode lay 142 on support tube inwall.
Wherein, the second electrode lay 142 is directly fitted and is fixed on the inwall of support tube 11.The first of first electrode layer 141
Hold the fixing end for being installed in power transmission shaft 12 middle part, the second end of first electrode layer 141 is the free end that can bend.Wherein,
First electrode layer 141 is contacted with each other with the second electrode lay 142.Alternatively, the length of first electrode layer 141 be more than from power transmission shaft to
The distance between support tube inwall, at this moment, first electrode layer 141 can bend due to being supported the stop of an inwall,
So as to contact with each other with the second electrode lay 142 on support tube inwall.In addition, in order that first electrode layer can be with second
The first end of first electrode layer can be fixed by electrode layer effective contact perpendicular to power transmission shaft 12, specifically, for the ease of
Fixing, retaining element, for example, sleeve with slot etc. can also be arranged further on power transmission shaft 12.Wherein, first electrode
Layer can be made using flexible material, so that can free bend.But, if the material of first electrode layer is excessively soft
Soft, when power transmission shaft rotates, first electrode layer will due to effect of inertia overbending, thus pressing close to power transmission shaft, so, first
Electrode layer will be unable to come in contact with the second electrode lay on support tube inwall, thus being unable to reach the effect of triboelectricity
Really.Therefore, the material of first electrode layer should be flexible moderate, both less hard and not too soft.Preferably, can be in first electrode layer
One layer of support member 140(is arranged on the first side surface referring to Fig. 3 a and Fig. 3 b), then this first electrode layer passes through the second side surface
Contact with each other with described the second electrode lay.The Main Function of this support member 140 is: first electrode layer is played with support and makees
With to prevent because first electrode layer is excessively soft the inwall away from support tube in rotary course.
Lower mask body introduces the structure of friction generator.In one embodiment of the invention, friction generator
First electrode layer includes: the first electrode being stacked and the first high molecular polymer insulating barrier, the second electricity of friction generator
