Wherein, supporting drum 11 can be pillar support cylinder, for example, can be cylindrical support cylinder or prismatic supporting drum etc.When supporting drum is prismatic supporting drum, can be the various shapes such as four prism type, hexagon.And supporting drum can be also other shapes such as pyramid type, the utility model is not construed as limiting this.In addition, the material of supporting drum 11 preferably has the material of Mechanics of Machinery support performance, for example, and high molecule plastic, stainless steel, glass, pottery or alloy type material etc.Transmission shaft 12 is positioned at the inside of supporting drum 11, and preferably, transmission shaft 12 is positioned at the central axis place of supporting drum 11, and stretch out from the inside of supporting drum 11 on the top of transmission shaft 12.The material of transmission shaft can be metal, pottery or wear-resisting and have macromolecular material of mechanical strength etc.During specific implementation, supporting drum is relative fixing with the position of transmission shaft, and transmission shaft can rotate with respect to supporting drum.In order to realize this point, supporting drum 11 can have a cylindrical or prismatic sidewall, has a diapire simultaneously, and transmission shaft is flexibly connected with the center portion of this diapire, and transmission shaft can be rotated with respect to supporting drum; Or, also can make supporting drum only have sidewall there is no diapire, the bottom of sidewall is fixed on a fixed position, simultaneously, at the central axis place of supporting drum, fix a base, transmission shaft inserts in this base and can in base, rotate freely, thereby transmission shaft can rotate with respect to supporting drum.In the utility model, the concrete means of fixation between supporting drum and transmission shaft is not limited, as long as can realize transmission shaft with respect to the object of supporting drum rotation.
Wind-driven part 13 is mainly used in driving above-mentioned transmission shaft rotation.Particularly, the first end of wind-driven part 13 is the fixed end that is installed in transmission shaft 12 tops, the free end of the second end of wind-driven part 13 for driving transmission shaft 12 to rotate with respect to supporting drum 11 under wind-force effect.Cup sheet of the flabellum that for example, the free end of this wind-driven part can be by fan, vane or the modes such as a blade of fan blade realize.Correspondingly, the free-ended shape of this wind-driven part can not limit its concrete shape in the utility model for various shapes such as fan-shaped, rectangular, circle or arcs, as long as be applicable to the shape of collection wind energy, all can adopt.In addition, in order to improve the efficiency of collecting wind energy, thereby impel transmission shaft to rotate quickly, the quantity of wind-driven part 13 can be for a plurality of, and at this moment, the angle between every two adjacent wind-driven parts preferably equates.In addition, for the ease of fixing above-mentioned one or more wind-driven parts, can also on transmission shaft, set firmly a sleeve, wind-driven part is fixed on transmission shaft by sleeve.
Under the drive of wind-driven part, as long as there is wind, transmission shaft will rotate with respect to supporting drum.Correspondingly, in the utility model, triboelectricity machine is divided into two-part separate and that be in contact with one another, a part is arranged on transmission shaft, and another part is arranged on supporting drum, like this, when there being wind out-of-date, this part the triboelectricity machine on transmission shaft of being arranged on is along with transmission shaft is rotated, and this part the triboelectricity machine being arranged on supporting drum keeps static, therefore, phase mutual friction constantly between the two, thus electric energy produced.

Lower mask body is introduced the structure of triboelectricity machine.In an embodiment of the present utility model, the first electrode layer of triboelectricity machine comprises: the first electrode of stacked setting and the first high molecular polymer isolation layer, the second electrode lay of triboelectricity machine comprises: the second electrode of stacked setting and the second high molecular polymer isolation layer, wherein, the first high molecular polymer isolation layer in the first electrode layer and the second high molecular polymer isolation layer in the second electrode lay are in contact with one another.In other words, the first electrode in the first electrode layer is set directly on the inwall of supporting drum, and the first high molecular polymer isolation layer covers on the first electrode.When the wind generating unit in the utility model comprises supporting part, a side surface of the second electrode in the second electrode lay is arranged on supporting part, on the opposite side surface of the second electrode, be further provided with the second high molecular polymer isolation layer, that is: the second electrode holder is between the second high molecular polymer isolation layer and supporting part.When transmission shaft rotates, by the sense of rotation of transmission shaft is set, the second high molecular polymer isolation layer in the second electrode lay is contacted with the first high molecular polymer isolation layer in the first electrode layer.
Fig. 2 shows the equivalent structure schematic diagram of the first electrode layer and the second electrode lay.In Fig. 2, in order to describe conveniently, the first electrode layer to be plotted as to horizontal structure, but in fact, the first electrode layer should be have certain crooked.As shown in Figure 2, the first electrode layer 141 in triboelectricity machine comprises the first electrode 1411 and the first high molecular polymer isolation layer 1412, and the second electrode lay 142 comprises the second electrode 1421 and the second high molecular polymer isolation layer 1422.
In the structure shown in Fig. 2, the first high molecular polymer isolation layer 1412 and the second high molecular polymer isolation layer 1422 are as two frictional interfaces of triboelectricity machine, lower mask body is introduced the principle of these two frictional interface triboelectricities: when transmission shaft rotates, the first electrode layer rotates thereupon, and the second electrode lay is relatively static, thereby first the first high molecular polymer isolation layer in the electrode layer second high molecular polymer isolation layer that will continue to rub in the second electrode lay, cause the first high molecular polymer isolation layer and the second high molecular polymer surface of insulating layer and because of friction, produce static charge, the generation of static charge can make the electric capacity between the first electrode and the second electrode change, thereby cause occurring potential difference between the first electrode and the second electrode.When the first electrode and the second electrode are communicated with by external circuit, this potential difference will form alternating-current pulse electrical signal in external circuit, thereby realizes the object of generating.In order to realize above-mentioned external circuit, can on the first electrode, connect a first contact conductor 15(referring to Fig. 1 b), on the second electrode, connect a second contact conductor 16(referring to Fig. 1 b), the output terminal using these two contact conductors as triboelectricity machine is connected with external circuit.Wherein, contact conductor can be realized by enamel covered wire.
In addition, in order to improve the generating capacity of triboelectricity machine, at least one face in two faces that the first high molecular polymer isolation layer 1412 and the second high molecular polymer isolation layer 1422 are in contact with one another, microstructure can be further set.Therefore, apparent surface's contact friction better of the first high molecular polymer isolation layer and the second high molecular polymer isolation layer, and induce more electric charge at the first electrode and the second electrode place.Above-mentioned microstructure specifically can be taked following two kinds of possible implementations: first kind of way is that this microstructure is micron order or nano level very little concaveconvex structure.This concaveconvex structure can increase surface friction drag, improves generating efficiency.Described concaveconvex structure can directly form when film preparation, and method that also can enough polishings makes the surface of the first high molecular polymer isolation layer and/or the second high molecular polymer isolation layer form irregular concaveconvex structure.Particularly, this concaveconvex structure can be the concaveconvex structure of semicircle, striated, cubic type, rectangular pyramid or the shape such as cylindrical.The second way is, this microstructure is the poroid structure of nanometer, now the first high molecular polymer isolation layer material therefor is preferably polyvinylidene fluoride (PVDF), and its thickness is the preferred 1.0mm of 0.5-1.2mm(), and the face of its relative the second electrode lay is provided with a plurality of nano-pores.Wherein, the size of each nano-pore, width and the degree of depth, can select according to the needs of application, and preferred nano-pore is of a size of: width is that 10-100nm and the degree of depth are 4-50 μ m.The quantity of nano-pore can output current value and magnitude of voltage as required be adjusted, and preferably these nano-pores are that hole pitch is being uniformly distributed of 2-30 μ m, and preferred average hole pitch is being uniformly distributed of 9 μ m.
In the triboelectricity machine of introducing in the above, the first electrode or the second electrode can be metal film, Graphene, silver nano line coating or other nesa coatings (such as AZO, FTO) etc. with electrical conductivity, or, can also be indium tin oxide, metal or alloy, wherein metal can be Au Ag Pt Pd, aluminium, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; Alloy can be aluminum alloy, titanium alloy, magnesium alloy, beryllium alloy, Cuprum alloy, zinc alloy, manganese alloy, nickel alloy, lead alloy, tin alloy, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungsten alloy, molybdenum alloy, niobium alloy or tantalum alloy.The first high molecular polymer isolation layer or the second high molecular polymer isolation layer can be a kind of in teflon, PET plastics, curing dimethyl silicone polymer, Kapton or doped zinc oxide nano-wire and the macromolecular materials such as polyvinylidene fluoride with microcellular structure; Or the first high molecular polymer isolation layer or the second high molecular polymer isolation layer can also be a kind of in the cellulose with microcellular structure, polyester fibre, artificial fiber.In addition, the first above-mentioned high molecular polymer isolation layer and the second high molecular polymer isolation layer can also be selected from respectively aniline-formaldehyde resin film, polyoxymethylene film, ethyl cellulose film, polyamide film, melamino-formaldehyde film, polyethyleneglycol succinate film, cellulose film, cellulose acetate film, polyethylene glycol adipate film, polydiallyl phthalate film, fiber (regeneration) sponge film, elastic polyurethane body thin film, styrene-acrylonitrile copolymer copolymer film, styrene-butadiene-copolymer film, artificial fiber film, poly-methyl film, methacrylic acid ester film, polyvinyl alcohol film, polyvinyl alcohol film, polyester film, polyisobutylene film, polyurethane flexible sponge film, pet film, polyvinyl butyral film, formaldehyde phenol film, neoprene film, butadiene-propylene copolymer film, natural rubber film, polyacrylonitrile film, a kind of in acrylonitrile vinyl chloride film and polyethylene the third diphenol carbonate thin film.Wherein, the material of the first high molecular polymer isolation layer and the second high molecular polymer isolation layer is preferably different, thereby can improve friction effect.The first above-mentioned high molecular polymer isolation layer and the second high molecular polymer isolation layer can prevent that the potential difference producing between the first electrode and the second electrode from neutralizing in inside.As can be seen here, in the triboelectricity machine of the four-layer structure shown in Fig. 2 (the first electrode, the first high molecular polymer isolation layer, the second high molecular polymer isolation layer and the second electrode), be mainly to generate electricity by the friction between polymer (the first high molecular polymer isolation layer) and polymer (the second high molecular polymer isolation layer).
In addition, except realizing the mode of triboelectricity machine by four-layer structure shown in Fig. 2, in other embodiments of the present utility model, can also adopt alternate manner to realize triboelectricity machine.For example, also can save the first high molecular polymer isolation layer or the second high molecular polymer isolation layer in above-mentioned four-layer structure, make triboelectricity machine become three-decker.When saving the first high molecular polymer isolation layer, the first electrode and the second high molecular polymer isolation layer rub as two frictional interfaces of triboelectricity machine, at this moment, can at least one face in two faces that the first electrode and the second high molecular polymer isolation layer are in contact with one another, be provided with microstructure equally; When saving the second high molecular polymer isolation layer, the second electrode and the first high molecular polymer isolation layer rub as two frictional interfaces of triboelectricity machine, at this moment, equally also can at least one face in two faces that the second electrode and the first high molecular polymer isolation layer are in contact with one another, be provided with microstructure, to improve generating efficiency.Electricity generating principle and the four-layer structure of the generator of three-decker are similar, repeat no more herein.In addition, in the generator of three-decker, by metal and polymer, rub, because metal easily loses electronics, therefore adopt metal and polymer friction can improve energy output.
Wherein, in the triboelectricity machine of three-decker, owing to having saved one deck high molecular polymer isolation layer, therefore, do not there is electrode in the electrode layer of high molecular polymer isolation layer because needs rub as friction electrode (being metal) and the first high molecular polymer isolation layer, therefore its material can be selected from metal or alloy, and wherein metal can be Au Ag Pt Pd, aluminium, nickel, copper, titanium, chromium, selenium, iron, manganese, molybdenum, tungsten or vanadium; Alloy can be aluminum alloy, titanium alloy, magnesium alloy, beryllium alloy, Cuprum alloy, zinc alloy, manganese alloy, nickel alloy, lead alloy, tin alloy, cadmium alloy, bismuth alloy, indium alloy, gallium alloy, tungsten alloy, molybdenum alloy, niobium alloy or tantalum alloy.Another electrode rubs owing to not needing, therefore,, except can selecting the above-mentioned metal or alloy material of enumerating, other materials that can make electrode also can be applied, for example, can also select the nonmetallic material such as indium tin oxide, Graphene, silver nano line film.The material of the high molecular polymer isolation layer in the triboelectricity machine of three-decker is identical with the material in four-layer structure, repeats no more herein.
Next, introduce the first electrode layer in triboelectricity machine and concrete quantity and the position relationship of the second electrode lay.
Fig. 3 a be take the triboelectricity machine of the three-decker a kind of position relationship schematic diagram between the first electrode 1411 of having exemplified the first electrode layer of triboelectricity machine and being comprised and the first high molecular polymer isolation layer 1412 and the second electrode 1421 that the second electrode lay was comprised, in addition, also show in the drawings supporting part 140.In Fig. 3 a, the quantity of the first electrode layer is three, and these three the first electrode layer intervals arrange, and the angle between every two adjacent the first electrode layers preferably equates.The second electrode lay comprises a plurality of interrupted sheet parts, and these a plurality of interrupted sheets are partly disposed on the inwall of supporting drum, and the interval of every two adjacent tabs between dividing preferably equates.In this implementation, each first electrode layer each interrupted sheet part that rubs successively when rotated, thereby between each first electrode layer and tabs that each is interrupted are divided, will produce potential difference, thereby make can effectively contact with separated between two frictional interfaces.In this mode, can on each first electrode layer, connect respectively first contact conductor, therefore, in the structure shown in Fig. 3 a, there are three the first contact conductors.Correspondingly, can also connect respectively second contact conductor in each tabs office of the second electrode lay, therefore, in the structure shown in Fig. 3 a, have four the second contact conductors.By adjusting the series parallel connection relation between these first contact conductors and the second contact conductor, can change the size of the curtage of triboelectricity machine output.
