Description

Technical Field

[0001] The invention relates to a self-cleaning hollow glass, in particular to a hollow glass which can be self-powered and dry-cleaned. Background Art

[0002] With the rapid development of modern architecture, high-rise buildings, owing to their advantages such as high space utilization and unique visual effects, have become a mainstream trend in modern urban construction. As core components of modern building facades, glass curtain walls and large glass panels are widely used for their transparent, beautiful appearance and excellent lighting. However, with long-term exposure to outdoor environments, glass surfaces are highly susceptible to contamination from dust, sand, and atmospheric pollutants, seriously affecting the building's appearance and performance. According to statistics, in heavily polluted urban areas, dust deposition on glass curtain walls can reach a rate of 0.5-1.2 mg / cm² per week, resulting in a 15-30% drop in glass transmittance in just one month, and a corresponding increase in lighting energy consumption within the building.

[0003] At present, existing glass cleaning technologies present diverse characteristics based on different dimensions, but most of them rely on manual cleaning. Although these methods can achieve dust removal effects to a certain extent, there are still some difficult-to-overcome problems, especially in terms of dust removal efficiency. Traditional manual cleaning methods are usually carried out by professionally trained cleaning personnel carrying high-pressure water guns, detergents, wipers and other tools, with the help of aerial work platforms, hanging baskets or Spider-Man equipment, and adopting a "top-down, piece-by-piece scrubbing" mode for cleaning. Although this method can rely on flexible manual operation to cope with different degrees of pollution, especially when dealing with stubborn stains, it can show flexible operability, but there are some defects: manual cleaning methods are obviously insufficient in dust removal, especially for long-term accumulated dust, fine particles or wind and sand, which cannot be efficiently and thoroughly removed, resulting in a lot of dust residue on the glass surface, affecting the light transmittance and appearance of the glass. In addition, the efficiency of manual cleaning is extremely low. Under normal circumstances, a single person can only clean an area of 50~80m per day. 2 For large buildings, this cleaning method is unable to meet the needs of rapid, large-scale cleaning. Dust accumulation is more severe in high-altitude areas, especially in hard-to-reach areas. Manual cleaning relies heavily on experience, which can lead to blind spots on glass and prevent comprehensive dust removal. Furthermore, cleaning costs are high, costing as much as 15 to 30 yuan per square meter. Furthermore, cleaning is typically performed only once or twice per quarter, a relatively frequent occurrence. This cumulative cost is substantial, increasing building maintenance expenses.

[0004] In order to overcome the shortcomings of manual cleaning, large-scale cleaning equipment has emerged. However, the initial equipment purchase cost can reach hundreds of thousands of yuan, and the five-year operation and maintenance cost accounts for 30-50% of the original value of the equipment, and the professional manual operation cost accounts for more than 60% of the total operation. At the same time, the high-pressure water gun cleans every 100m 2 Water consumption is 500-1000L, and chemical cleaning agents reach tons annually. Equipment technology is severely outdated, relying on traditional mechanical mechanisms such as high-pressure water guns and rotating brushes. These devices are ineffective against the long-term accumulation of fine dust and pollutants on high-rise building surfaces. Particularly in windy and dusty environments, traditional equipment is inefficient and fails to meet the high-efficiency dust removal requirements of modern high-rise buildings. Furthermore, cleaning operations rely excessively on manual experience, with a repetitive cleaning rate reaching 25%, further exacerbating energy waste. Operating these devices poses significant chronic health risks. Operators are exposed to chemical cleaning agents such as hydrofluoric acid and surfactants, resulting in a higher incidence of respiratory diseases than the general population. High-voltage equipment operation is noisy, increasing the risk of hearing loss. Vibration from overhead cranes can trigger chronic joint problems in operators. Operators experience significantly higher rates of anxiety due to equipment shaking and restricted vision, exceeding those of ordinary workers. This leads to increased operational errors, further exacerbating safety risks.

[0005] A variety of innovative cleaning technology solutions have also emerged. Super-hydrophilic coatings alter the wettability of glass surfaces by applying special materials, allowing water droplets to spread and remove stains. While simple to operate and capable of self-cleaning to a certain extent, they are susceptible to erosion from UV rays, wind, and sand over extended periods of outdoor exposure, leading to degradation and failure. Furthermore, super-hydrophilic coatings are limited in their effectiveness against dust particles, particularly large or persistent dust particles, where the spreading action of water alone is insufficient to achieve optimal cleaning results. Photocatalytic cleaning technologies utilize photocatalytic materials such as titanium dioxide to generate strong oxidizing free radicals under light, decomposing organic stains on the glass surface. However, these technologies are highly dependent on light conditions, with cleaning efficiency plummeting at night or in low-light environments. Furthermore, photocatalytic technology primarily targets organic stains and is less effective against dust particles. This is especially true in windy and dusty environments, where dust and sand easily adhere to the glass surface. Even after photocatalytic treatment, residual dust remains difficult to completely remove, requiring rainwater or manual cleaning.

[0006] Therefore, the present invention is proposed. Summary of the Invention

[0007] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and to provide a self-powered hollow glass for dry cleaning. Relying on the low surface energy characteristics of the super-hydrophobic coating, electrostatic collection and conduction of static charges to reduce the adhesion of dust particles to the surface of the outer glass, and then through wind stripping, dry waterless self-cleaning is achieved, reducing water resource waste. At the same time, self-powered cleaning eliminates the risks of manual high-altitude operations.

[0008] In order to achieve the above-mentioned purpose, the present invention is a self-powered hollow glass for dry cleaning, comprising a frame and glass installed in the frame, wherein any frame portion of the frame is provided with groove one and groove two, which are arranged back to back and extend in the length direction of the frame portion, a fan assembly is provided in groove one and is evenly distributed along the extension direction of groove one, the fan assembly comprises a generator motor and turbine blades, the turbine blades are installed on the shaft of the generator motor, and a guide structure is formed at the opening of groove one to guide the airflow generated by the fan assembly to flow close to the surface of the outer glass, a rechargeable battery power supply system is provided in groove two and is electrically connected to the fan assembly, an ITO conductive film layer and a super-hydrophobic coating are compounded in sequence on the surface of the outer glass, and an electrode is provided on the ITO conductive film layer to be electrically connected to the rechargeable battery power supply system, a flexible thin-film solar cell is provided in the hollow layer between the inner glass and the outer glass, and is compounded on any glass surface, and an electrode is provided on the flexible thin-film solar cell to be electrically connected to the rechargeable battery power supply system.

[0009] When the above-mentioned self-powered dry-cleaning insulating glass is driven by natural wind and suspended dust in the environment falls onto the surface of the outer glass, the super-hydrophobic coating coated on the surface makes it easy for the dust to roll on the surface due to its low surface energy. Interfacial friction occurs between the dust particles and the super-hydrophobic coating, generating electrostatic charge on the coating surface. An ITO conductive film attached to the bottom of the coating uses a current collecting structure to collect the charges separated at the interface along a preset path to the remote electrode, ultimately outputting a stable micro-ampere current, thereby achieving dust power generation. At the same time, the flexible thin-film solar cells located in the hollow layer of the insulating glass can achieve solar power generation, while the generator motor in the fan assembly can achieve wind power generation. In other words, a three-source synergistic self-powered system is constructed, effectively integrating dust friction power generation, solar power generation, and micro-wind power generation. This allows the system to continuously collect and store energy under sunlight, wind, and the movement of air particles, achieving energy self-sufficiency.

[0010] When cleaning is required, when wind or mechanical vibration causes dust particles to slide relative to the coating surface, due to the triboelectric effect, a clear charge separation will occur between the dust and the coating material - the dust is negatively or positively charged, while the coating is oppositely charged. When the surface charge generated by the triboelectric effect penetrates through the superhydrophobic coating into the ITO conductive film layer, the conductive network immediately introduces the excess charge into the electric field circuit, so that the surface potential can be maintained in a state close to equilibrium with no residual static electricity, thereby reducing electrostatic adsorption.

[0011] A set of fan assemblies are installed on the side of the glass frame, using turbine blades to blow dust particles away from the glass surface. The ejected airflow accelerates the rolling of particles on the conductive film, further triggering the triboelectric effect, secondary power generation and recovery, realizing waterless cleaning and waste utilization.

[0012] The above-mentioned self-powered hollow glass for dry cleaning, in which the guide structure is preferably selected to include: a guide baffle, which transitions from the opening of groove one to the surface of the outer glass and extends in the length direction of groove one, and the surface of the guide baffle is provided with a bionic design structure of the nodules on the flippers of a humpback whale.

[0013] The baffle's surface features a bionic design inspired by the nodules on a humpback whale's flippers. This delays airflow separation and enhances vortex formation, optimizing airflow distribution. This allows the small vortices behind the nodules to flow close to the outer glass surface, forming "air scrapers" that effectively remove smog particles. Furthermore, this bionic design allows the generator motor to start at low wind speeds when harvesting wind energy, improving starting torque compared to traditional designs.

[0014] In the structure of the self-powered dry-cleaning insulating glass, the surface of the super-hydrophobic coating is preferably a composite nano-scale sealing resin coating.

[0015] The sealing resin coating is nanometer-to-micrometer-scale and has excellent conformality. This means that the sealing resin coating can evenly cover the surface contours of the original super-hydrophobic coating's micro-nano rough structures without filling or flooding these structures, achieving the purpose of protecting the super-hydrophobic coating while maintaining its low surface energy properties.

[0016] In the structure of the self-powered dry-cleaning insulating glass, a cover plate is preferably provided at the opening of the second groove, which is hinged to the frame.

[0017] The cover plate can protect the rechargeable battery power supply system in the groove 2 to prevent it from being accidentally touched or hit.

[0018] The core of the self-powered dry-cleaning insulating glass obtained by the present invention lies in: a self-sufficient energy system composed of photovoltaic, micro-wind and nano-friction power generation modules, and equipped with a reversibly driven micro-fan, so that it can not only collect environmental energy around the clock, but also remove dust on the surface of the outer glass without the need for external water source when needed.

[0019] Compared with the prior art, the present invention has the following technical effects: Highly efficient multi-source power generation capability effectively covers three environmental conditions: sunlight, wind, and particle movement, enabling all-weather energy collection and storage.

[0020] Significantly improve the self-cleaning efficiency, adopting a three-element collaborative dust removal method of super-hydrophobic coating, airflow stripping, and charge neutralization, which increases the dust removal efficiency by about 35% compared with single wind cleaning. It is completely dry and does not rely on water sources, overcoming the limitations of traditional self-cleaning technology in rainy, snowy or high-humidity environments.

[0021] Extend the cleaning cycle and reduce operation and maintenance costs. The cleaning cycle is extended from the traditional 3 to 6 months to 12 to 18 months, reducing the frequency of high-altitude maintenance; the annual operation and maintenance costs of large projects can be reduced by 10 to 15%.

[0022] It eliminates the safety risks of manual cleaning at heights, reducing the annual average high-altitude operation accident rate of 0.3%. It also eliminates the need for an external water source, saving approximately 500 L / 100 m² of water per cleaning, and eliminating the discharge of cleaning agents and wastewater, meeting the needs of green buildings and sustainable development.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, as an embodiment of the present invention, a self-powered dry-cleaning insulating glass provided in this embodiment includes a frame 1 and a glass 2 installed in the frame 1. Any frame portion of the frame 1 is provided with a groove 1-1 and a groove 2 1-2, which are arranged back to back and extend in the length direction of the frame portion. A fan assembly is provided in the groove 1-1 and is evenly distributed along the extension direction of the groove 1-1. The fan assembly includes a generator motor 3 and a turbine fan blade 4. The turbine fan blade 4 is installed on the shaft of the generator motor 3 and forms a guide at the opening of the groove 1-1. The airflow generated by the fan assembly flows close to the guide structure of the outer glass 2 surface. A rechargeable battery power supply system 5 is provided in the groove 1-2 and is electrically connected to the fan assembly. An ITO conductive film layer 6 and a super-hydrophobic coating 7 are compounded in sequence on the surface of the outer glass 2, and an electrode is provided on the ITO conductive film layer 6 to be electrically connected to the rechargeable battery power supply system 5. A flexible thin-film solar cell 8 is provided in the hollow layer between the inner glass 2 and the outer glass 2 and is compounded on the surface of any glass 2. An electrode is provided on the flexible thin-film solar cell 8 to be electrically connected to the rechargeable battery power supply system 5.

[0027] The diversion structure described in this embodiment includes: a diversion baffle 9, which transitions from the opening of the groove 1-1 to the surface of the outer layer of glass 2 and extends in the length direction of the groove 1-1. The surface of the diversion baffle 9 is provided with a bionic design structure of the nodules on the flippers of a humpback whale.

[0028] In this embodiment, a cover plate 11 is provided at the opening of the groove 2 1-2, which is hinged to the frame 1. The cover plate 11 can protect the rechargeable battery power supply system 5 in the groove 2 1-2 from being accidentally touched or hit.

[0029] In the above-mentioned self-powered dry-cleaning insulating glass, when fine dust suspended in the natural wind-driven environment falls onto the surface of the outer glass 2, the super-hydrophobic coating 7 coated on its surface, due to its low surface energy characteristics, makes it easy for the dust to roll on the surface. Interfacial friction occurs between the dust particles and the super-hydrophobic coating 7, generating electrostatic charge on the coating surface. The ITO conductive film attached below the coating uses a current collecting structure to collect the charges separated at the interface along a preset path to the distal electrode, ultimately outputting a stable microampere current, thereby achieving dust power generation. At the same time, the flexible thin-film solar cell 8 located in the hollow layer of the insulating glass can achieve solar power generation, while the generator in the fan assembly can achieve wind power generation. That is, a three-source collaborative self-powered system is constructed, effectively integrating dust friction power generation, solar power generation, and micro-wind power generation, so that the system can continuously collect and store energy under sunlight, wind, and air particle movement, achieving energy self-sufficiency.

[0030] When cleaning is required, when wind or mechanical vibration causes dust particles to slide relative to the coating surface, due to the triboelectric effect, a clear charge separation will occur between the dust and the coating material - the dust is negatively or positively charged, while the coating is oppositely charged. When the surface charge generated by the triboelectric effect penetrates through the super-hydrophobic coating 7 to the ITO conductive film layer 6, the conductive network immediately introduces the excess charge into the electric field circuit, so that the surface potential can be maintained in a state close to equilibrium with no residual static electricity, thereby reducing the electrostatic adsorption force.

[0031] A fan assembly and a baffle 9 are positioned on the side of the glass 2 frame 1. The baffle 9's surface features a bionic design structure reminiscent of the nodules on the flippers of a humpback whale. This delays airflow separation and enhances vortex generation, thereby optimizing airflow distribution. This allows the small vortices behind the nodules to flow close to the surface of the outer glass 2, forming an "air scraper" that effectively removes haze particles and other matter, blowing dust particles away from the surface of the glass 2. The ejected airflow accelerates the rolling of particles on the conductive film, further triggering the triboelectric effect, generating secondary power recovery, and achieving waterless cleaning and waste recycling. Furthermore, this bionic design enables the generator motor 3 to start at low wind speeds when harvesting wind energy, improving starting torque compared to traditional designs.

[0032] As a second embodiment of the present invention, a self-powered dry-cleaning insulating glass provided in this embodiment has a general structure consistent with the first embodiment described above. Figure 5 As shown, in this embodiment, a nano-scale sealing resin coating 10 is compounded on the surface of the super-hydrophobic coating 7 .

[0033] The sealing resin coating 10 is nanometer to micrometer-scale and has excellent conformality. This means that the sealing resin coating 10 can evenly cover the surface contours of the micro-nano rough structures of the original super-hydrophobic coating 7 without filling or flooding these structures, achieving the purpose of protecting the super-hydrophobic coating 7 while not affecting its low surface energy properties.

[0034] Finally, the self-powered dry cleaning performance of the insulating glass of the present invention was verified by experimental means. The experimental process is as follows: Selection: Four LGT88Y-130 130 ohm ITO conductive films, size 0.06237m 2 *4; two Haoyang Photovoltaic Technology GIGS copper indium gallium flexible thin-film solar cells (water-blocking film), measuring 203mm*294mm*0.28mm; a 5V USB voltage regulator; two 20mm*20mm*0.5mm copper plate electrodes; three rechargeable LiPo 3.7V, 2000mAh batteries; a 5V input voltage, 9V output voltage reversible dual-purpose electric motor (generator) and turbine blades; rectifier diodes and DC-DC step-up modules; 6.3V 10000μF electrolytic capacitors; several copper wires; a breadboard; conductive sealing resin spray; OEING ® Super hydrophobic coating liquid; thin film circuit conductive silver glue.

[0035] Rinse the glass with dishwashing liquid and water to remove obvious stains. Use a spray bottle to evenly apply an appropriate amount of anhydrous ethanol to the glass surface. Use absorbent paper to wipe the glass surface in a single direction, repeating several times until the glass surface is free of grease. Use a hair dryer on the cold air setting to dry the anhydrous ethanol. Use tweezers to evenly apply the ITO conductive film to the glass surface, ensuring there are no bubbles or wrinkles. Adjust the hair dryer to the high temperature setting and evenly sweep the film at a distance of 20 cm from the ITO conductive film for about 30 minutes to avoid local overheating. After heating, let it stand at room temperature for ten minutes.

[0036] Pour the super-hydrophobic coating material into a spray bottle and apply it vertically at a constant speed 20 cm from the glass surface. Spray it in 20-30 layers, leaving five minutes between each layer to dry. Apply the coating in a cross-coating pattern: spray the first layer horizontally, the second layer vertically, and the third layer horizontally. Repeat this process until the coating is complete. Then, let the glass sit for 24 hours to allow the film to form.

[0037] Apply silver conductive glue to the edges of the four conductive films and connect them in parallel using wires. Select the lead-out area in the middle of the four connected conductive films and apply conductive silver glue there. Press one end of each wire onto the silver glue. Use a hair dryer to heat and cure the glue to enhance the connection stability. Solder the other ends of the two wires to two copper sheets. Connect the four rectifier diodes as if they were a bridge rectifier circuit, connecting the two copper sheets to the two input terminals of the rectifier circuit. Connect the positive terminal of the battery to the positive output terminal of the rectifier circuit via wire, and the negative terminal of the battery to the negative output terminal of the rectifier circuit. Once the connections are complete, spray the resin sealant. Wait half an hour after the first spraying before spraying again. Allow 12 hours for the film to form.

[0038] A flexible thin-film solar cell is attached to the hollow layer of the double-layer glass. The two solar cells are connected in series with wires to a total power of 15.4W. The positive output end is connected to the positive terminal of the USB voltage regulator, and the negative terminal is connected to the negative terminal. After voltage stabilization, the positive and negative terminals are connected to the two ends of the rechargeable battery for charging.

[0039] 3D printing technology was used to create the wind power generation and window frame design. The frame measures 1190mm*740mm*135mm, and features a switchable side panel for easy installation of the fan assembly and circuit connections. A micro-generator motor with turbine blades is embedded horizontally. When cleaning is not required, natural wind blows horizontally, driving the turbine blades to generate wind power. When cleaning is required, the electricity stored in the two power generation methods described above and the electricity stored in wind power generation are combined to activate the generator motor, driving the blades to rotate, creating forced convection on the window surface to break up dust adhesion on the glass. As dust leaves the glass surface under the fan's influence, friction regenerates electric charges, which are then collected in the manner described above. Simultaneously, a low-pressure area forms behind the fan, drawing in ambient air, creating air circulation and accelerating dust dispersion and removal, thereby achieving a dust removal effect.

[0040] At the same time, the humpback whale bionic nodule baffle is used to block rain and protect the glass surface circuit, while increasing the flow rate in the horizontal direction, enhancing the efficiency of wind power generation, and optimizing the self-cleaning effect.

[0041] Experimental results: The system can generate approximately 58 Wh of electricity per day per unit area (1 m²), of which approximately 0.38 Wh comes from dust friction, 49.9 Wh from solar power, and 7.584 Wh from wind power.

[0042] Economic benefit calculation: Take five fan modules in parallel as an example. The generator motor of each fan module outputs 9V. The daily power generation can be used to start the generator motor for 20 minutes (a larger capacity battery can be used to increase the starting time of the generator motor).2 The cleaning fee for the device includes: 20 yuan (photovoltaic panel) + 60 yuan (conductive film) + 80 yuan (super-hydrophobic coating) + 35 yuan (fan assembly) + 20 yuan (material fee) = 215 yuan / m 2 . To clean 10000m 2 Taking high-rise glass as an example, the total cost of this device over five years is 215 * 10,000 = 2,150,000 yuan. The labor cleaning cost is: [20 (number of workers) * 2,140 (high-risk occupational insurance premium) + 20 * 2,000 (training fee) + 8 * 10,000 (glass cleaning fee)] * 5 + 80 * 10,000 (cleaning coating) + 200,000 (consumables) + 400 * 30 * 10 * 5 (supervisors) = 2,414,000 yuan. Without considering the operating costs of the outsourcing company, the final cost savings for the device is 1 - (2,150,000 / 2,414,000) = 11%.

[0043] Cleaning efficiency: Adhesion force F'a=(1−α)Fa, α=0.7, wind shear force τ ≈ 21*1.2*52*0.002≈0.03N / m 2 , so ηw is taken as 0.5; Coulomb force Fe=Q*E≈5×10−10N, so ηe is taken as 0.3, η=1−(1−ηw)(1−ηe)(1−α)=89.5%>0.5, 89%−50%=39%.

[0044] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
