[0002] It is common to install anti-dazzle plates in the center of highways, but the anti-dazzle plates currently used are mostly made of glass steel or PVC, which are limited in service life. If not properly designed, the high-speed wind field will generate a continuous torsion on the anti-dazzle plate, causing damage, resulting in high maintenance costs and secondary injuries in traffic accidents.

[0003] The speed of cars on highways is relatively fast, which can generate strong wind pressure around their paths. These wind pressures can be collected and utilized as wind energy.

It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiments of the present application, and is not used to limit the embodiments of the present application.

[0054] The application discloses a road anti-dazzle device which can be installed in a highway central separation belt as one of candidates of a highway anti-dazzle board, collects energy of vehicle wake flow, converts the energy into electric energy, and provides necessary electric energy for a sensing system or a traffic signal lamp.

[0055] Figure 1 Figure 1 is a general structure diagram of the road anti-dazzle device of the application, the road anti-dazzle device comprises a plurality of anti-dazzle units, each anti-dazzle unit comprises a light shield plate 31, a connecting shaft, and a frictional electrification module 2, the light shield plate 31 is fixedly connected with the connecting shaft, the connecting shaft is rotatably connected with the frictional electrification module 2, so as to drive the frictional electrification module 2 to generate an electric signal, and the plurality of anti-dazzle units are detachably connected in series. Figure 1 Figure 2 is a structure diagram of the anti-dazzle unit of the road anti-dazzle device of the application, the lowermost end of figure 2 shows one set of anti-dazzle units, the light shield plate 31 is located at the lowermost end of each anti-dazzle unit, when wind resistance occurs, the light shield plate 31 rotates, thereby driving the entire frictional electrification module 2 to generate an electric signal, each anti-dazzle unit further comprises a partition cover 12, the partition cover 12 separates the anti-dazzle units, the partition cover 12 can shield the frictional electrification module 2, thereby protecting the frictional electrification module 2, so as to ensure that internal temperature and humidity of the frictional electrification module 2 change at a relatively stable level, and the upper and lower ends of each partition cover 12 are provided with nuts, which are used for adjusting the contact tightness of a rotor and a stator in the frictional electrification module 2, so as to control the output electric signal to be optimal.

[0056] The anti-glare device can also have a support structure, including: a top cover 1, a base 32, and a plurality of support rods 13 connected with the top cover 1 and the base 32. The top cover 1 is located at the uppermost end of the entire device, which can block rain and prevent direct exposure to the sun. The top cover 1 is made of high-temperature-resistant material, such as PLA material, and can be 3D printed. The base 32 is located at the lowermost end of the entire device, usually in the form of a disc, which can stabilize the base. The base 32 can be 3D printed or made by cutting at least one acrylic plate with a laser cutting machine. The number, thickness, and diameter of the acrylic plate can be adjusted according to different application scenarios. Preferably, the thickness of the plate is 0.5-2 cm, and the diameter is 150-300 mm. More preferably, the thickness of the plate is 1 cm, and the diameter is 230 mm. The anti-glare unit is penetrated by a plurality of support rods 13, which can be threaded rods fixed with nuts between the partition cover 13. In this way, if one anti-glare unit is damaged, it can be replaced at any time by simply unscrewing the fixing nuts and replacing the damaged parts of the anti-glare unit. Preferably, the support rods 13 are made of three parallel stainless steel screws, which are evenly arranged around the anti-glare device to support the stability of the entire device. Preferably, the diameter of the stainless steel screw is 2-10 mm, and the length is 10-100 cm. More preferably, the diameter is 5 mm, and the length is 50 cm.

[0057] The light barrier 31 includes a plurality of leaves. Preferably, the light barrier 31 of the present embodiment is composed of four peripheral leaves, which are mainly designed by 3D printing. In order to cope with the harsh environment such as direct exposure to the sun, rain, dust, and exhaust gas on the highway, the leaves are made of high-performance nylon material that is resistant to corrosion and high temperature, and can withstand a temperature of 250°C or above. In addition, the nylon material used for the leaves is a biodegradable and environmentally friendly material, and the hardness of the nylon material is as high as 105HK, which is more than twice the hardness of traditional anti-glare plate material glass steel. Even if a traffic accident occurs, it will not cause secondary damage due to the destruction of the device, greatly improving the safety of the traffic road. At the same time, in order to make more efficient use of wind energy, the leaves fully utilize fluid mechanics to design a Savonius type appearance to ensure that the leaves still have good power output at low wind speed, so as to drive the rotation of the connecting shaft through the power generated by any wind resistance, and at the same time drive the frictional electrification module to generate electrical signals.

[0058] The connecting shaft of each anti-glare unit can be detachable, which can be divided into three segments connected by hinges, and each segment of the connecting shaft can support one anti-glare unit. In this case, each anti-glare unit is completely independent, so as to rotate independently at different speeds by utilizing wind speeds of different heights, thereby improving the efficiency and stability of wind energy collection. However, in the application scenario where the wind speed difference between layers is not large, the connecting shaft can also be integrated, such as Figure 2As shown, the scheme makes the module structure parts of the anti-glare device as a whole reduced, and the manufacturing is simpler, and since the connecting shaft is integrally through the whole anti-glare device, it is more conducive to improve the stability of the overall structure. Specifically, in this embodiment, the connecting shaft includes the optical axis 21 and the bearing 24, the optical axis 21 is located at the center of the triboelectric module 2 and integrally through the whole road anti-glare device, that is, the optical axis 21 traverses the whole light shield plate 31 and the triboelectric module 2, and plays a role of fixing and supporting. The bearing 24 is fixed on the triboelectric module 2, and the optical axis 21 is rotatably connected with the triboelectric module through the bearing 24. In order to ensure the hardness of the connecting shaft, the optical axis 21 and the bearing 24 are both made of hard material, and the optical axis 21 and the bearing 24 can be made of the same material or different materials, preferably, the optical axis 21 is made of stainless steel material, and the bearing 24 is made of ceramic material. In addition, the diameter of the optical axis 21 is 6-10mm, preferably, the diameter of the optical axis 21 is 8mm, and the bearing 24 is designed with an industrial bearing to ensure the stability of the structure.

[0059] The triboelectric module 2 is coaxially installed from top to bottom in order, which includes the optical axis 21, the PCB circuit board 22, the stator 23, the bearing 24, the rotor 25, and the acrylic substrate 26. The whole triboelectric module 2 is packaged with the acrylic substrate 26 and the PCB circuit board 22, and the stator 23, the bearing 24, and the rotor 25 are covered therein. When the wind resistance comes, the rotor 25 rotates relative to the stator 23. The rotor 25 and the stator 23 can be made by 3D printing or laser cutting machine cutting at least one acrylic plate. The number, thickness and diameter of the acrylic plate can be adjusted according to different application occasions, preferably, the thickness is 0.5-2cm, and the diameter is 150-300mm; more preferably, the thickness is 1cm, and the diameter is 230mm. In addition, the triboelectric module 2 also includes an external electrode made of copper electrode material for leading out the generated electric signal.

[0060] The triboelectric module 2 is preferably a TENG (Triboelectric Nanogenerator). The structure of the TENG is generally rotor on top and stator on bottom, but such a design actually has some defects. The friction between the rotor and the stator will inevitably cause electrostatic adsorption between them. With the long operation of the rotor, the contact between the rotor and the stator will be more and more close, which will inevitably increase the wear between them, and will reduce the friction output and the power generation efficiency after a long time. It may cause the module to be stuck and unable to rotate, especially in the application scenario of the highway, it is difficult to maintain in time. In order to solve this problem, preferably, the anti-dazzle device of the application adopts the structure design of stator 23 on top and rotor 25 on bottom. The rotor 25 is tightly attached to the upper surface of the fan blade. When the fan blade rotates, it drives the rotor 25 to rub with the stator 23. Since the rotor 25 is on the lower part, the upward force generated by electrostatic adsorption and the gravity of the rotor 25 cancel each other out, so that the position of the rotor 25 remains relatively stable, thereby ensuring the stable output of the entire power generation device. The structure designed in this way will not have the problem of reduced device output after a long time of use, ensuring the robustness and stability of the anti-dazzle device.

[0061] Reference Figure 3 The triboelectric module further comprises triboelectric materials, the rotor is attached with a first triboelectric material, and the stator is attached with a second triboelectric material; the first triboelectric material is opposite to the second triboelectric material, so that the rotor 25 can generate an electric signal by rubbing when rotating relative to the stator 23. Specifically, the friction surface side of the rotor 25 is attached with a double-sided tape to attach the first triboelectric material. Preferably, the first triboelectric material comprises a first non-conductive material 27 and a first conductive material 28. The first non-conductive material 27 used to make the friction layer of the TENG comprises various types of polymer friction layer materials with strong electron-capturing ability, such as Kapton, PTFE, FEP, etc. The first conductive material 28 is a nylon film, both of which are attached to the rotor 25.

[0062] The stator 23 is composed of a substrate of acrylic material and a PCB circuit board, and the second triboelectric material is a second conductive material 29. Preferably, rabbit hair is selected as the second conductive material 29 in the application. The PCB circuit board plated with copper film can not only be used as a stator but also as a friction layer. The PCB circuit board 22 adopts a bare copper gold plating process to enhance its conductivity and corrosion resistance, and can ensure the continuous occurrence of the triboelectric effect.

[0063] In order to produce the electric signal more efficiently, the first triboelectric material 27 and the first dielectric material 28 are staggered, and the friction between the two and the second dielectric material 29 can produce a very high voltage output. Preferably, the first triboelectric material 27 and the first dielectric material 28 used to make the TENG are alternately attached to the surface of the rotor 25 in a uniform and periodic grid electrode structure, and the copper electrodes 20 on the friction layer of the stator 23 are left with a gap of a certain size between each other, preferably 3-10 mm, and more preferably 4 mm. A plurality of rabbit hairs are uniformly attached in the gap between the copper electrodes 20, also forming a periodic grid electrode structure, and preferably the number of rabbit hairs is three. The total number of interdigital grid electrodes on the stator 23 is equivalent to the total number of grid electrodes on the friction layer of the rotor 25, and the output signal is finally led out by the copper electrodes 20 on the surface of the stator 23 and the wires connected thereto. The generated electric quantity is stored in the capacitor through the circuit management module, and is ready to power the device in need of use.

[0064] As shown in Figure 4 The circuit management module includes a power generation component TENG, a full-wave rectifier bridge, a voltage stabilizing gas discharge tube GDT, an inductive element LC, etc., wherein the triboelectric module 2 is the power generation component TENG of the circuit management module. The direct current power after the full-wave rectifier bridge is injected into the LC oscillation circuit through the GDT, and finally stored in the capacitor for subsequent use. The voltage stabilizing gas discharge tube GDT can realize the function of overvoltage protection. This circuit management module can convert mechanical energy into electrical energy signals by using the power generation component TENG, and can change the alternating current signal output by the TENG into a direct current signal that can be used by daily sensors after rectification, thereby realizing the function of real-time power supply for related sensing devices; at the same time, it realizes the rapid storage and release of electrical signals, and achieves the effect of rapid charging of the entire device in the working state.

[0065] The working process of the road anti-dazzle device of the present application will be described below Figure 5

[0066] S11, the light shield is rotated under the action of external wind resistance: the anti-dazzle device is caused to rotate by external wind resistance, wherein the external wind resistance includes wake energy when a car passes and natural wind energy, and the anti-dazzle device includes a plurality of anti-dazzle units, which are detachably connected in series;

[0067] S12, the rotating light shield is transmitted through the connecting shaft, and simultaneously drives the rotor in the triboelectric module to rotate relative to the stator, and the connecting shaft of each anti-dazzle unit can be detachable or integral;

[0068] ​S13, the friction electrification module rotates and rubs: the first friction material on the surface of the rotor rubs the second friction material on the surface of the stator to transfer charges, generate an electric signal, and under the coupling effect of friction electrification and electrostatic induction, the electric signal will be outputted outward;

[0069] Specifically, the friction of the rotor and the stator surface friction material can generate a stable voltage of 2kV, the charging current can reach 25uA, the transferred charge is about 200nC, and the overvoltage protection function is realized through the circuit management module. In a specific example, the output stability of the device is tested by using a fine standard experimental test platform, and the platform accuracy can reach 0.1mm. At the same time, the fine tuning rotary handle in the test platform can ensure the absolute distance between the rotor and the stator. The data graph shown in Figure 6 As the fan blade speed increases, the friction electrification current increases from the original 5uA to 60uA, and the voltage gradually stabilizes at about 2.3kV, which indicates that the output electric signal of the device is positively correlated with the wind speed.

[0070] S14, current signal processing: including leading out and rectifying the generated electric signal, the alternating current signal outputted by the TENG is rectified into direct current signal which can be used by daily sensor, to ensure the normal use of sensing equipment or electrical equipment.

[0071] The present application forms a road anti-glare device by connecting multiple anti-glare units in series, and the multiple anti-glare units can independently collect wind energy for power generation, thereby more effectively utilizing wind energy of different heights, improving the efficiency and stability of wind energy collection, and achieving the purpose of anti-glare and efficient wind energy collection. At the same time, the present application adopts a modular three-level structure design, which is convenient to disassemble and replace at any time, and ensures the application cost.

[0072] The anti-glare device also has the following advantages:

[0073] (1) The light blocking structure is designed as a unique fan blade structure, which reduces the resistance on the panel and can be used at low wind speed;

[0074] (2) The contact tightness of the rotor and the stator in the friction electrification module can be adjusted to control the output electric signal;

[0075] (3) The structure design of the stator on the top and the rotor on the bottom keeps the position of the rotor stable, ensuring the stable output of the entire power generation device;

[0076] (4) The selection of friction electrification material and the staggered grid electrode structure can produce extremely high and stable voltage output.

[0077] The above merely provides an example of the present application, and is not intended to limit the present application.
