Description

Power generation system using nano friction generator

Technical field

The present invention relates to the field of nanotechnology, and more particularly to a power generation system employing a nano-friction generator.

Background technique

In daily life, people use wind power or solar power as a more common method. Among them, the principle of wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of the rotation by the speed increaser to promote the generator to generate electricity. According to the current windmill technology, the wind speed of about three meters per second (the degree of breeze) can start generating electricity. Wind power is forming a boom in the world, because wind power does not require the use of fuel, nor does it generate radiation or air pollution. However, conventional wind turbines are bulky and costly, and cause great inconvenience to users during transportation and installation. Solar power directly converts solar energy into electrical energy. This method has a high energy conversion rate, but the application time range is small, and it cannot be used at night or in rainy weather. When using a wind turbine to generate electricity, its time limit is strong. Under the condition of no wind for many days, normal power generation cannot be performed, which affects the stability of the live electricity. In the above situation, the combination of solar power generation and wind turbine generation can complement the shortcomings. However, when two devices are used to generate electricity at the same time, manual switching is required, which is not only cumbersome but also does not achieve good results.

Alternatively, the energy storage circuit 56 may be an energy storage component such as a lithium ion battery, a nickel hydrogen battery, a lead acid battery, or a super capacitor.

The power generation system shown in Figure 5 is characterized by the use of solar modules and nano-friction generators to alternately charge the energy storage circuit, wherein the nano-friction generator collects wind energy and the solar modules collect solar energy. This kind of circuit design is flexible and can be automatically switched according to the actual situation. When the solar energy is sufficient, the solar module is used to charge the energy storage circuit, and the nano friction generator is stopped, which extends the use of the nano friction generator and the rectifier circuit. Lifetime; In the case of insufficient solar energy, the nano-friction generator is used to charge the energy storage circuit, which greatly improves the power generation efficiency of the whole system.

The structure and working principle of the nano-friction generator in a power generation system using a nano-friction generator will be described in detail below. The first structure of a nano-friction generator is shown in Figures 6a and 6b. Fig. 6a and Fig. 6b respectively show a schematic perspective view and a cross-sectional structural view of a first structure of a nano-friction generator. The nano-friction generator includes: a first electrode 61, a first polymer insulating layer 62, and a second electrode 63 which are sequentially stacked. Specifically, the first electrode 61 is disposed on the first side surface of the first polymer insulating layer 62; and the second side surface of the first polymer insulating layer 62 is in contact with the surface of the second electrode 63 and Charge is induced at the second electrode 63 and the first electrode 61. Therefore, the first electrode 61 and the second electrode 63 described above constitute two output ends of the nano friction generator.

In order to increase the power generation capability of the nano-friction generator, a nanostructure 64 is further provided on the second side surface of the first polymer insulating layer 62 (i.e., the surface opposite to the second electrode 63). Therefore, when the nano-friction generator is pressed, the opposing surfaces of the first polymer-polymer insulating layer 62 and the second electrode 63 can better contact the friction and are induced at the first electrode 61 and the second electrode 63. More charge. Since the second electrode 63 is mainly used for rubbing with the first polymer insulating layer 62, the second electrode 63 may also be referred to as a friction electrode.

The micro-nano structure 64 can adopt the following two possible implementations. The first way is that the micro-nano structure is a very small concave-convex structure of micrometer or nanometer. The uneven structure can increase frictional resistance and improve power generation efficiency. The uneven structure can be formed directly at the time of film preparation, and the surface of the first polymer insulating layer can be formed into an irregular uneven structure by a grinding method. Specifically, the concave-convex structure may be semicircular, striped, cubic, quadrangular, Or a concave-convex structure of a cylindrical shape or the like. In the second mode, the micro/nano structure is a nano-scale pore structure, and the material used for the first polymer insulating layer is preferably polyvinylidene fluoride (PVDF), and the thickness thereof is 0.5-1.2 mm (preferably 1.0 mm). And a plurality of nanopores are disposed on a surface of the second electrode. The size of each nanopore, that is, the width and depth, can be selected according to the needs of the application. The preferred size of the nanopore is: a width of 10-100 nm and a depth of 4-50 μm. The number of nanopores can be adjusted according to the required output current value and voltage value. Preferably, the nanopores are uniformly distributed with a pore spacing of 2-30 μm, and more preferably a uniform distribution of average pore spacing of 9 μm.

The working principle of the nano-friction generator shown in Figures 6a and 6b will be specifically described below. When the layers of the nano-friction generator are squeezed, the second electrode 63 in the nano-friction generator rubs against the surface of the first polymer-polymer insulating layer 62 to generate an electrostatic charge, and the generation of the static charge causes the first electrode The capacitance between the 61 and the second electrode 63 is changed, resulting in a potential difference between the first electrode 61 and the second electrode 63. Since the first electrode 61 and the second electrode 63 are connected to the energy storage device as the output end of the nano friction generator, the energy storage device constitutes an external circuit of the nano friction generator, and the two output ends of the nano friction generator are equivalent to being The external circuit is connected. When the layers of the nano-friction generator are restored to the original state, the internal potential formed between the first electrode and the second electrode disappears, and the balanced first electrode and the second electrode are again generated. Reverse potential difference. By repeatedly rubbing and recovering, a periodic AC pulse electrical signal can be formed in the external circuit.

According to the research of the inventors, the metal rubs against the polymer, and the metal is more likely to lose electrons. Therefore, the friction between the metal electrode and the polymer can improve the energy output. Therefore, correspondingly, in the nano-friction generator shown in FIGS. 6a and 6b, the second electrode is required to be rubbed as a friction electrode (ie, metal) with the first high-molecular polymer, so that the material thereof may be selected from metal or Alloy, wherein the metal may be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, tin, iron, manganese, phase, tungsten or vanadium; the alloy may be an aluminum alloy, a titanium alloy, a magnesium alloy, a tantalum alloy , copper alloys, alloys, manganese alloys, nickel alloys, lead alloys, tin alloys, cadmium alloys, niobium alloys, indium alloys, gallium alloys, tungsten alloys, molybdenum alloys, niobium alloys or niobium alloys. Since the first electrode does not need to be rubbed, in addition to the material of the second electrode listed above, other materials capable of fabricating the electrode may be applied, that is, the first electrode may be selected from a metal or an alloy. The metal may be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, tin, iron, manganese, phase, tungsten or vanadium; the alloy may be aluminum alloy, titanium alloy, magnesium alloy, niobium alloy, copper Alloy, alloy, manganese alloy, nickel alloy, lead Alloys, tin alloys, cadmium alloys, niobium alloys, indium alloys, gallium alloys, tungsten alloys, molybdenum alloys, niobium alloys or niobium alloys may also be selected from non-metals such as indium tin oxide, graphene, and silver nanowire films. material.

In the structure shown in Fig. 6a, the first polymer insulating layer and the second electrode are directly opposed to each other and pasted together by the tape of the outer edge, but the present invention is not limited thereto. A plurality of elastic members, such as springs, may be disposed between the first polymer insulating layer and the second electrode, and the springs are distributed on the outer edges of the first polymer insulating layer and the second electrode for forming the first An elastic support arm between the polymer polymer insulating layer and the second electrode. When an external force acts on the nano-friction generator, the nano-friction generator is squeezed, and the spring is compressed, so that the first polymer-polymer insulation layer contacts the second electrode to form a friction interface; when the external force disappears, the spring bounces, so that The first polymer insulating layer is separated from the second electrode, and the nano-friction generator is restored to its original state.

The second structure of the nano-friction generator is shown in Figures 7a and 7b. 7a and 7b are respectively a perspective structural view and a cross-sectional structural view of a second structure of a nano-friction generator. The nano-friction generator includes: a first electrode 71, a first polymer insulating layer 72, a second polymer insulating layer 74, and a second electrode 73 which are sequentially stacked.

The first electrode 71 and the second electrode 73 constitute two output ends of the nano friction generator.

In order to increase the power generation capability of the nano-friction generator, at least one of the two faces of the first polymer-polymer insulating layer 72 and the second polymer-polymer insulating layer 74 are provided with a micro-nano structure. In Fig. 7b, a micro-nano structure 75 is provided on the surface of the first polymer insulating layer 72. Therefore, when the nano-friction generator is squeezed, the opposing surfaces of the first polymer insulating layer 72 and the second polymer insulating layer 74 can better contact the friction, and at the first electrode 71 and the second More charge is induced at the electrode 73. The above micro-nano structure can be referred to the above description, and will not be described again here.

The operation of the nano-friction generator shown in Figures 7a and 7b is similar to that of the nano-friction generator shown in Figures 6a and 6b. The only difference is that when the nanometers shown in Figures 7a and 7b When the layers of the friction generator are pressed, the surfaces of the first polymer insulating layer 72 and the second polymer insulating layer 74 rub against each other to generate an electrostatic charge. Therefore, the working principle of the nano-friction generator shown in FIGS. 7a and 7b will not be described herein.

The outer edge of the insulating layer 74 is used to form an elastic support arm between the first polymer insulating layer 72 and the second polymer insulating layer 74. When an external force acts on the nano-friction generator, the nano-friction generator is squeezed, and the spring 70 is compressed, so that the first polymer-polymer insulating layer 72 is in contact with the second polymer-polymer insulating layer 74 to form a friction interface; When it disappears, the spring 70 bounces, so that the first polymer insulating layer 72 is separated from the second polymer insulating layer 74, and the nano friction generator returns to the original state.
