Description

TECHNICAL FIELD

The single crystal silicon cell has the highest conversion efficiency, followed by the polycrystalline silicon, and the thin film cell has lower cost but slightly weaker efficiency. The output voltage of the photovoltaic power generation panel is usually 12V, 24V, etc. The direct current can be converted into 220V alternating current through an inverter.

[0023] In some embodiments, radar detectors 4 are fixedly installed on the left and right sides of the top of the mounting frame 1, and the radar detectors 4 are used to detect weather conditions, and the radar detectors 4 are electrically connected to the controller.

[0024] By using the above technical scheme, the radar detectors 4 on the top of the mounting frame 1 can monitor the weather conditions in real time, such as rainfall and dust, and transmit the data to the controller, so as to realize intelligent scheduling of the cleaning time, such as pausing cleaning in rainy days and starting in advance after dust, which saves energy consumption compared with fixed period cleaning, and avoids invalid loss of the cleaning mechanism in bad weather, thereby prolonging the service life of the equipment.

[0025] In some embodiments, a servo motor 8 is installed inside the first hollow groove 5, a worm 9 is connected to the right side output end of the servo motor 8, and the right side of the worm 9 is rotatably connected to the inside of the mounting frame 1.

[0026] By using the above technical scheme, the servo motor 8 in the first hollow groove 5 drives the worm 9 to rotate, providing power for the lifting and rotation of the cleaning roller 16, and the output torque can be adjusted according to the stain intensity, which adapts to the cleaning needs of different pollutants and ensures that stubborn stains are completely removed.

[0027] In some embodiments, worm gears 10 are rotatably connected to the bottom of the mounting frame 1 inside the mounting frame 1, and the worm gears 10 are rotatably connected to the bottom of the mounting frame 1 inside the mounting frame 1.

[0028] By using the above technical scheme, the meshing transmission of the worm 9 and the worm gear 10 converts the rotary motion of the servo motor 8 into the vertical rotation of the threaded rod 11, which drives the cleaning roller 16 to stably lift, avoids scratching the surface of the power generation panel body 3 during the cleaning process, and protects the integrity of the anti-reflection coating.

[0029] In some embodiments, the threaded rod 11 is threadedly connected to a slider 12 on its outer side, and the slider 12 is slidably connected to a groove inside the mounting frame 1. Furthermore, a rotating rod 13 is rotatably connected to the side of the slider 12 closest to the cleaning roller 16.

[0030] Using the above technical solution, the slider 12 on the outside of the threaded rod 11 slides along the groove of the mounting frame 1, providing guidance for the lifting and lowering of the cleaning roller 16. In conjunction with the rotation connection of the rotating rod 13, the cleaning roller 16 is always in contact with the surface of the power generation plate, and the stain removal rate in the corner area is improved.

[0031] In some embodiments, gears 14 are connected to the outer side of the rotating rod 13, and a rack 15 is meshed with the rear side of the gear 14, and the rear side of the rack 15 is fixedly installed on the rear side inside the mounting frame 1.

[0032] Using the above technical solution, the gear 14 on the outside of the rotating rod 13 meshes with the rack 15, and rotates synchronously during the lifting and lowering of the cleaning roller 16, forming a composite cleaning trajectory with synchronous lifting and rotation. This improves the stain removal efficiency compared to simple lifting and lowering cleaning, and is especially suitable for removing dried mineral deposits. The light transmittance after cleaning is restored to its initial value.

[0034] Using the above technical solution, the ultrasonic transducer 18 inside the cleaning roller 16 generates high-frequency vibration, which, together with the nano-carbon fiber bristles, can break down the intermolecular forces of stubborn stains, such as the protein coagulation layer of bird droppings. The stain removal rate is improved compared to a simple brush. The bristle material is soft and wear-resistant, reducing the wear rate on the generator plate body 3 and avoiding surface damage.

[0035] In some embodiments, a filter screen 20 is provided on the top of the rainwater collection tank 19, and a sloping drainage channel 21 is provided on the inner edge of the rainwater collection tank 19.

[0036] Using the above technical solution, the filter screen 20 at the top of the rainwater collection tank 19 intercepts impurities such as fallen leaves and dust, and the inclined diversion channel 21 concentrates and guides the rainwater. The collected rainwater can meet the cleaning water demand after treatment, and saves water resources compared with tap water flushing in water-scarce areas.

[0037] In some embodiments, a first filter membrane 22 is disposed between the rainwater collection tank 19 and the first exchange interlayer 23, and the first exchange interlayer 23 is filled with a strong acid styrene-based cation exchange resin.

[0038] Using the above technical solution, the strong acid styrene-based cation exchange resin in the first filter membrane 22 and the first exchange interlayer 23 can remove calcium and magnesium ions from rainwater, avoid the formation of scale on the surface of the power generation panel after cleaning, reduce secondary pollution compared to using tap water directly, and ensure stable light transmittance.

[0039] In some embodiments, a second filter membrane 24 is disposed between the first exchange interlayer 23 and the second exchange interlayer 25, and the interior of the second exchange interlayer 25 is filled with a strong base styrene-based anion exchange resin. A plurality of solenoid valves 26 are disposed below the second exchange interlayer 25, and a spray head 27 is connected to the bottom of each solenoid valve 26.

[0040] Using the above technical solution, the strong alkaline anion exchange resin in the second filter membrane 24 and the second exchange interlayer 25 further adsorbs chloride ions, sulfate ions, etc. in the rainwater, and sprays them precisely through the spray head 27 controlled by the solenoid valve 26. This is suitable for neutralizing and cleaning salt spray in coastal areas, and improves the salt removal rate compared to simply rinsing with water, thus protecting the metal frame of the power generation panel from corrosion.

[0041] Compared with the prior art, the beneficial effects of the present invention are: 1. Composite cleaning and intelligent adaptation enhance power generation efficiency and stability: The cleaning roller 16 integrates ultrasonic transducer 18 for high-frequency vibration, and nano-level carbon fiber bristles for lifting and rotating friction, combined with precise spraying treated by ion exchange, forming a composite cleaning system of vibration peeling, physical wiping and chemical purification. This improves the removal rate of stubborn stains. At the same time, radar detector 4 monitors the weather in real time and dynamically adjusts the cleaning intensity and timing through controller linkage with servo motor 8 to adapt to the characteristics of pollutants in different regions, reducing energy consumption and ensuring that the light transmittance of the power generation panel remains stable at more than 95% of the initial value.

[0042] 2. Utilizing rainwater for purification and cleaning, saving water, protecting the environment and ensuring safety, and reducing operation and maintenance costs: The rainwater collection tank 19 collects rainwater through the filter screen 20 and the inclined diversion channel 21. The first exchange layer 23 removes calcium and magnesium ions, and the second exchange layer 25 adsorbs chloride ions, etc. The deionized water is precisely used by the spray head 27 controlled by the solenoid valve 26, saving water consumption and avoiding scale and salt residue.

[0043] One embodiment of this application includes: a photovoltaic power generation panel with a surface cleaning mechanism, comprising a mounting frame 1, a mounting bracket 2 fixedly mounted on the rear side of the mounting frame 1, and a power generation panel body 3 fixedly mounted inside the mounting bracket 2, a first slot 5 opened on the left side of the mounting frame 1, and second slots 6 opened on both the left and right sides of the inner edge of the mounting frame 1, and a third slot 7 opened above the inner edge of the mounting frame 1, and the interior of the mounting frame 1 is a hollow structure, a rainwater collection trough 19 is provided at the top of the mounting frame 1, and a first exchange interlayer 23 is provided inside the rainwater collection trough 19, and a second exchange interlayer 25 is provided below the first exchange interlayer 23, and a plurality of spray heads 27 are provided below the second exchange interlayer 25, and the spray heads 27 are located above the third slot 7, and a cleaning roller 16 is provided inside the third slot 7, and the cleaning roller 16 has a lifting and rotating structure, and a plurality of ultrasonic transducers 18 are provided inside the cleaning roller 16.

[0044] Radar detectors 4 are fixedly installed on the top left and right sides of the mounting frame 1. The radar detectors 4 are used to detect weather conditions and are electrically connected to the controller. The radar detectors 4 on the top of the mounting frame 1 can monitor weather conditions in real time, such as rain and sandstorms, and transmit the data to the controller to realize intelligent scheduling of cleaning time, such as pausing cleaning on rainy days and starting cleaning in advance after sandstorms. This saves energy compared to fixed-cycle cleaning, avoids ineffective wear and tear on the cleaning mechanism under severe weather conditions, and extends the service life of the equipment.

[0045] A servo motor 8 is installed inside the first slot 5, and a worm gear 9 is connected to the right output end of the servo motor 8. The right side of the worm gear 9 is rotatably connected to the inside of the mounting frame 1. Worm wheels 10 are meshed with the rear sides of both sides of the worm gear 9, and the bottom of the worm wheels 10 is rotatably connected to the bottom surface inside the mounting frame 1. A threaded rod 11 is connected to the upper end of the worm wheel 10, and the threaded rod 11 is rotatably connected to the left and right sides inside the mounting frame 1. A slider 12 is threadedly connected to the outer side of the threaded rod 11, and the slider 12 is slidably connected to the slide groove inside the mounting frame 1. A rotating rod 13 is rotatably connected to the side of the slider 12 closest to the cleaning roller 16. The servo motor 8 in the first slot 5 drives the worm gear 9 to rotate. The servo motor 8 provides power for the lifting and rotation of the cleaning roller 16. Its output torque can be adjusted according to the intensity of the stains to adapt to the cleaning needs of different pollutants and ensure that stubborn stains are completely removed. The meshing transmission of the worm gear 9 and the worm wheel 10 converts the rotational motion of the servo motor 8 into the vertical rotation of the threaded rod 11, which drives the cleaning roller 16 to lift and lower smoothly, avoiding scratches on the surface of the generator plate body 3 during the cleaning process and protecting the integrity of the anti-reflective coating. The slider 12 on the outside of the threaded rod 11 slides along the groove of the mounting frame 1 to guide the lifting and lowering of the cleaning roller 16. With the rotational connection of the rotating rod 13, the cleaning roller 16 is always in contact with the surface of the generator plate, improving the stain removal rate in the corner areas.

[0046] Gears 14 are connected to the outer side of the rotating rod 13, and a rack 15 is meshed with the rear side of the gear 14. The rack 15 is fixedly installed on the rear side of the inner side of the mounting frame 1. The cleaning roller 16 is provided with a mounting rod 17, and several ultrasonic transducers 18 are fixedly installed on the outer side of the mounting rod 17. Nanoscale carbon fiber bristles are provided on the outer side of the cleaning roller 16. The gears 14 and rack 15 on the outer side of the rotating rod 13 mesh with each other, and rotate synchronously during the lifting and lowering of the cleaning roller 16, forming a composite cleaning trajectory of simultaneous lifting and rotation. This improves the stain removal efficiency compared to simple lifting and lowering cleaning, and is especially suitable for removing dried mineral deposits. The light transmittance after cleaning recovers to the initial value, which is improved. The ultrasonic transducers 18 inside the cleaning roller 16 generate high-frequency vibrations, which, together with the nanoscale carbon fiber bristles, can break down the intermolecular forces of stubborn stains, such as the protein coagulation layer of bird droppings. The stain removal rate is improved compared to a simple brush. The bristle material is soft and wear-resistant, reducing the wear rate on the generator plate body 3 and avoiding surface damage.

[0047] A filter screen 20 is installed at the top of the rainwater collection tank 19, and a sloping drainage channel 21 is provided on the inner edge of the rainwater collection tank 19. A first filter membrane 22 is provided between the rainwater collection tank 19 and the first exchange interlayer 23, and the first exchange interlayer 23 is filled with a strong acid styrene-based cation exchange resin. A second filter membrane 24 is provided between the first exchange interlayer 23 and the second exchange interlayer 25, and the second exchange interlayer 25 is filled with a strong base styrene-based anion exchange resin. Several solenoid valves 26 are provided below the second exchange interlayer 25, and each solenoid valve 26 is connected to a spray head 27. The filter screen 20 at the top of the rainwater collection tank 19 intercepts impurities such as fallen leaves and dust, and the sloping drainage channel 21 diverts rainwater... The collected rainwater, after treatment, can meet the water demand for cleaning, saving water resources compared to rinsing with tap water in water-scarce areas. The strong acid styrene-based cation exchange resin in the first filter membrane 22 and the first exchange interlayer 23 can remove calcium and magnesium ions from the rainwater, preventing scale formation on the surface of the power generation panel after cleaning. This reduces secondary pollution compared to using tap water directly and ensures stable light transmittance. The strong base anion exchange resin in the second filter membrane 24 and the second exchange interlayer 25 further adsorbs chloride ions, sulfate ions, etc. from the rainwater. The spray head 27, controlled by the solenoid valve 26, sprays precisely, which is suitable for neutralizing and cleaning salt spray in coastal areas. This improves the salt removal rate compared to rinsing with clean water and protects the metal frame of the power generation panel from corrosion.

[0048] The working principle of the photovoltaic panel with a surface cleaning mechanism described in this application includes: In use, the radar detector 4 on the top of the mounting frame 1 monitors weather conditions in real time, such as sandstorms, rainfall, and pollutant concentrations, and transmits the data to the controller. When the accumulated dirt on the surface of the power generation panel 3 reaches a preset threshold or a specific weather condition is detected, the controller triggers the cleaning program, activating the servo motor 8 in the first slot 5. The servo motor 8 outputs power to drive the worm gear 9 to rotate. The worm gear 9 meshes with the worm wheels 10 on both sides, driving the threaded rod 11 to rotate synchronously. The slider 12 on the outside of the threaded rod 11 slides along the internal groove of the mounting frame 1, realizing the vertical lifting and lowering of the cleaning roller 16. Meanwhile, the rotating rod 13 on the slider 12 moves with the lifting and lowering, and its outer gear 14 meshes with the fixed spur rack 15, driving the cleaning roller 16 to rotate synchronously, forming a composite cleaning trajectory of lifting and rotating, ensuring that the entire surface of the power generation panel is covered. Several ultrasonic transducers 18 are fixed on the mounting rod 17 inside the cleaning roller 16, which generate high-frequency vibrations of 20-40kHz during the cleaning process. The vibrations are transmitted to the surface of the power generation panel through nano-level carbon fiber bristles. The rainwater collection tank 19 at the top of the mounting frame 1 intercepts impurities through the filter screen 20, and the inclined drainage channel 21 concentrates and guides the rainwater. Rainwater is filtered sequentially through the first filter membrane 22, the first exchange interlayer 23 to remove cations such as calcium and magnesium, the second filter membrane 24, and the second exchange interlayer 25 to remove anions such as chloride and sulfate, thus completing deionization purification. The purified water is controlled by the solenoid valve 26 and precisely sprayed onto the surface of the power generation panel through the spray head 27. Combined with the friction of the cleaning roller 16, the stain removal effect is enhanced, while avoiding the scale residue caused by directly using tap water. After the cleaning program is completed, the servo motor 8 reverses, driving the cleaning roller 16 back to the initial position in the third empty slot 7. The solenoid valve 26 closes and stops spraying. The entire process is fully automatic and requires no manual intervention.

For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
