For fully understanding the object of the present invention, feature and effect, by following concrete mode of execution, the present invention is elaborated, but the present invention is not restricted to this.
The invention discloses a kind of wind generating unit and wind-power generating system, in order to solve complicated, the with high costs problem of wind power generation device structure of the prior art.
Fig. 1 a shows the external structure schematic diagram of wind generating unit provided by the invention, and Fig. 1 b shows the internal view of wind generating unit provided by the invention.Can find out with reference to Fig. 1 a to Fig. 1 b, this wind generating unit comprises: supporting drum 11, transmission shaft 12, at least one wind-driven part 13 and the friction generator be made up of the first electrode layer 141 and the second electrode lay 142.
Wherein, supporting drum 11 can be pillar support cylinder, such as, can be cylindrical support cylinder or prismatic supporting drum etc.When supporting drum is prismatic supporting drum, it can be the various shape such as four prism type, hexagon.And supporting drum can be also other shapes such as pyramid type, and the present invention is not construed as limiting this.In addition, the material of supporting drum 11 preferably has the material of Mechanics of Machinery support performance, such as, 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 the top of transmission shaft 12 is stretched out from the inside of supporting drum 11.The material of transmission shaft can be metal, pottery or wear-resisting and have the macromolecular material etc. of mechanical strength.During specific implementation, supporting drum is relative with the position of transmission shaft fixing, and transmission shaft can rotate relative to supporting drum.In order to realize this point, supporting drum 11 can have a cylindrical or prismatic sidewall, has a diapire simultaneously, is flexibly connected by transmission shaft with the center portion of this diapire, and transmission shaft can be rotated relative to supporting drum; Or, also supporting drum can be made to only have sidewall there is no diapire, the bottom of sidewall is fixed on a fixed position, simultaneously, a base is fixed at the central axis place of supporting drum, transmission shaft to insert in this base and can rotate freely in base, and thus transmission shaft can rotate relative to supporting drum.In the present invention, the concrete means of fixation between supporting drum and transmission shaft is not limited, as long as the object that transmission shaft rotates relative to supporting drum can be realized.
Wind-driven part 13 is mainly used in driving above-mentioned transmission shaft to rotate.Particularly, the first end of wind-driven part 13 is the fixed end being installed in transmission shaft 12 top, and the second end of wind-driven part 13 is the free end that transmission shaft 12 can be driven under wind-force effect to rotate relative to supporting drum 11.Such as, the free end of this wind-driven part can be realized by modes such as blades of a cup sheet of of a fan flabellum, vane or fan blade.Correspondingly, the shape of the free end of this wind-driven part can be the various shapes such as fan-shaped, rectangular, circle or arc, does not limit, as long as the shape being applicable to collecting wind energy all can adopt in the present invention to its concrete shape.In addition, in order to improve the efficiency of collecting wind energy, thus impel transmission shaft to rotate quickly, the quantity of wind-driven part 13 can be multiple, and at this moment, the angle between two often adjacent wind-driven parts is preferably equal.In addition, for the ease of fixing above-mentioned one or more wind-driven parts, a sleeve can also be set firmly on transmission shaft, wind-driven part is fixed on transmission shaft by sleeve.
Under the drive of wind-driven part, as long as there is wind to blow over, transmission shaft will rotate relative to supporting drum.Correspondingly, in the present invention, friction generator is divided into separate and two-part contacted with each other, 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 friction generator be arranged on transmission shaft is rotated along with transmission shaft, and this part friction generator be arranged on supporting drum then keeps static, therefore, therebetween will phase mutual friction constantly, thus produce electric energy.
Lower mask body introduces above-mentioned two-part of friction generator.As shown in Figure 1 b, the part in friction generator is the first electrode layer 141 be positioned on transmission shaft, and another part is the second electrode lay 142 be positioned on supporting drum inwall.
Wherein, the second electrode lay 142 is directly fitted and is fixed on the inwall of supporting drum 11.The first end of the first electrode layer 141 is be installed in the fixed end in the middle part of transmission shaft 12, and the second end of the first electrode layer 141 is the free end that can bend.Wherein, the first electrode layer 141 contacts with each other with the second electrode lay 142.Alternatively, distance the length of the first electrode layer 141 is greater than from transmission shaft to supporting drum inwall, at this moment, the first electrode layer 141 can bend owing to being subject to the stop of supporting drum inwall, thus can contact with each other with the second electrode lay 142 on supporting drum inwall.In addition, in order to enable the first electrode layer effectively contact with the second electrode lay, the first end of the first electrode layer can be fixed perpendicular to transmission shaft 12, particularly, for the ease of fixing, on transmission shaft 12, fixed element can also be set further, such as, with the sleeve etc. of slot.Wherein, the first electrode layer can adopt flexible material to make, so that can free bend.But, if the material of the first electrode layer is too soft, when transmission shaft rotates, first electrode layer will due to effect of inertia overbending, thus press close to transmission shaft, like this, the first electrode layer cannot come in contact with the second electrode lay be positioned on supporting drum inwall, thus cannot reach the effect of triboelectricity.Therefore, the material of the first electrode layer should be flexible moderate, both not too hard also not too soft.Preferably, one deck supporting part 140(can be set on the first side surface of the first electrode layer see Fig. 3 a and Fig. 3 b), then this first electrode layer is contacted with each other by the second side surface and described the second electrode lay.The Main Function of this supporting part 140 is: play a supporting role to the first electrode layer, to prevent because the first electrode layer is too soft away from the inwall of supporting drum in rotary course.
Lower mask body introduces the structure of friction generator.In one embodiment of the invention, first electrode layer of friction generator comprises: the first electrode of stacked setting and the first high molecular polymer isolation layer, the second electrode lay of friction generator 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 contact with each other.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 then covers on the first electrode.When the wind generating unit in the present invention comprises supporting part, a side surface of the second electrode in the second electrode lay is arranged on the supporting member, the opposite side of the second electrode is then provided with the second high molecular polymer isolation layer on the surface further, that is: the second electrode holder is between the second high molecular polymer isolation layer and supporting part.When transmission shaft rotates, by arranging the sense of rotation of transmission shaft, 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 horizontal structure, but in fact, the first electrode layer should be have certain bending.As shown in Figure 2, the first electrode layer 141 in friction generator 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, first high molecular polymer isolation layer 1412 and the second high molecular polymer isolation layer 1422 are as two frictional interfaces of friction generator, lower mask body introduces the principle of these two frictional interface triboelectricities: when drive axis, first electrode layer rotates thereupon, and the second electrode lay geo-stationary, thus the first high molecular polymer isolation layer in the first electrode layer will the second high molecular polymer isolation layer in continuous frictional the second electrode lay, the first high molecular polymer isolation layer and the second high molecular polymer surface of insulating layer is caused to produce static charge because of friction, the generation of static charge can make the electric capacity between the first electrode and the second electrode change, thus cause occurring potential difference between the first electrode and the second electrode.When the first electrode is communicated with by external circuit with the second electrode, this potential difference will form alternating-current pulse electrical signal in external circuit, thus realizes the object of generating.In order to realize above-mentioned external circuit, a first contact conductor 15(can be connected on the first electrode see Fig. 1 b), connect a second contact conductor 16(on the second electrode see Fig. 1 b), the output terminal of these two contact conductors as friction generator 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 friction generator, 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 contact with each other can arrange microstructure further.Therefore, the apparent surface of the first high molecular polymer isolation layer and the second high molecular polymer isolation layer can contact friction better, and induces more electric charge at the first electrode and the second electrode place.Above-mentioned microstructure specifically can take the implementation that the following two kinds is possible: first kind of way is, 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 directly can be formed when film preparation, also the surface of the first high molecular polymer isolation layer and/or the second high molecular polymer isolation layer can be made to form irregular concaveconvex structure by the method for polishing.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 nanometer cavernous structure, 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 multiple nano-pore.Wherein, the size of each nano-pore, i.e. width and the degree of depth, can select according to the needs of application, preferred nano-pore is of a size of: width is 10-100nm and the degree of depth is 4-50 μm.The quantity of nano-pore can output current value as required and magnitude of voltage adjust, and preferably these nano-pores are hole pitch is 2-30 μm being uniformly distributed, and preferred average hole pitch is 9 μm being uniformly distributed.
In friction generator presented hereinbefore, first electrode or the second electrode can be have the metal film of electrical conductivity, Graphene, silver nano line coating or other nesa coatings (such as AZO, FTO) etc., 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.First high molecular polymer isolation layer or the second high molecular polymer isolation layer can be teflon, PET, the dimethyl silicone polymer of solidification, Kapton or doped zinc oxide nano-wire and the one had in the macromolecular materials such as the polyvinylidene fluoride of microcellular structure; Or the first high molecular polymer isolation layer or the second high molecular polymer isolation layer can also be have the one in the cellulose of 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 aniline-formaldehyde resin film respectively, 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 films, 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 films, pet film, polyvinyl butyral film, formaldehyde-phenol film, neoprene film, butadiene-propylene copolymer film, natural rubber films, polyacrylonitrile film, one in acrylonitrile vinyl chloride film and polyethylene 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, thus can improve friction effect.The first above-mentioned high molecular polymer isolation layer and the second high molecular polymer isolation layer can prevent the potential difference that produces between the first electrode and the second electrode in inside and.As can be seen here, in the friction generator of the four-layer structure (the first electrode, the first high molecular polymer isolation layer, the second high molecular polymer isolation layer and the second electrode) shown in Fig. 2, mainly generated 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 except the mode of friction generator by four-layer structure shown in Fig. 2, in other embodiments of the invention, alternate manner can also be adopted to realize friction generator.Such as, also can save the first high molecular polymer isolation layer in above-mentioned four-layer structure or the second high molecular polymer isolation layer, make friction generator become three-decker.When saving the first high molecular polymer isolation layer, first electrode and the second high molecular polymer isolation layer rub as two frictional interfaces of friction generator, at this moment, at least one face in two faces that can contact with each other at the first electrode and the second high molecular polymer isolation layer is equally provided with microstructure; When saving the second high molecular polymer isolation layer, second electrode and the first high molecular polymer isolation layer rub as two frictional interfaces of friction generator, at this moment, at least one face in two faces that equally also can contact with each other at the second electrode and the first high molecular polymer isolation layer is 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, rubbed by metal and polymer, because metal easily loses electronics, therefore adopt metal and polymer friction to improve Energy transmission.
Wherein, in the friction generator of three-decker, owing to eliminating one deck high molecular polymer isolation layer, therefore, not having electrode in the electrode layer of high molecular polymer isolation layer due to needs rubs as friction electrode (i.e. 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 is not owing to needing to rub, therefore, except can selecting the above-mentioned metal or alloy material enumerated, other materials that can make electrode also can be applied, such as, the nonmetallic material such as indium tin oxide, Graphene, silver nano line film can also be selected.The material of the high molecular polymer isolation layer in the friction generator of three-decker is identical with the material in four-layer structure, repeats no more herein.
Next, concrete quantity and the position relationship of the first electrode layer in friction generator and the second electrode lay is introduced.
