The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The embodiment of the present invention provides a solar photovoltaic lightning protection device, such as Figure 1-15As shown, the solar photovoltaic lightning protection device includes: a mounting frame 1, a support frame 2 is fixedly installed at the bottom of the mounting frame 1, a plurality of solar panels 3 and a cleaning mechanism are fixedly installed on the mounting frame 1, and the cleaning mechanism is used to clean the surfaces of the plurality of solar panels 3; a line control box 4, a battery 5 and a lightning protection mechanism are fixedly installed on the support frame 2, the line control box 4 connects the plurality of solar panels 3 and the battery 5, and the lightning protection mechanism is arranged on one side of the mounting frame 1; the cleaning mechanism includes two side baffles 6, two cross beams 7, a drive screw 8, a scraper strip 9 and a rubber strip 10, two The side baffles 6 are respectively fixedly mounted on both sides of the top of the mounting frame 1, the two cross beams 7 are fixedly mounted between the two side baffles 6, the driving screw 8 is rotatably mounted on the two cross beams 7, the scraper 9 is slidably mounted between the two side baffles 6, the scraper 9 is threadedly sleeved on the driving screw 8 so that the scraper 9 is driven to slide when the driving screw 8 rotates, the rubber strip 10 is stuck in the bottom of the scraper 9, and the top of the rubber strip 10 is located in the same plane as the upper surface of the multiple solar panels 3, so that the rubber strip 10 can scrape off surface impurities of the multiple solar panels 3 when it slides.

[0020] In this embodiment, the mounting frame 1 is first secured in place and supported by a support frame 2. Multiple solar panels 3 are then mounted on the mounting frame 1 and connected to a control box 4. Furthermore, a battery 5 is installed on the support frame 2 and connected to the control box 4 to store electrical energy. A lightning protection mechanism is installed on one side of the mounting frame 1 to protect the entire system from lightning strikes.

[0021] The cleaning mechanism is used to clean the surface of the solar panel 3. The rotation of the drive screw 8 drives a scraper bar 9 to slide along the side guard 6. A rubber strip 10 engages the bottom of the scraper bar 9, with its top flush with the top surface of the solar panel 3. As the scraper bar 9 slides, it removes impurities from the surface of the solar panel 3, keeping it clean and improving power generation efficiency.

[0022] The lightning protection mechanism is located on one side of the mounting frame 1. Through the grounding device and the lightning protection device, it effectively guides the lightning current to be safely discharged, protecting the solar power generation system from damage caused by lightning.

[0023] The cleaning mechanism can automatically clean the surface of the solar panel 3 by driving the screw 8 and the scraper 9. The design of the rubber strip 10 ensures thorough cleaning, effectively removing impurities such as dust and bird droppings, avoiding frequent manual cleaning and saving manpower and time costs.

[0024] By regularly cleaning the surface of the solar panels 3, impurities that hinder light absorption are reduced, improving power generation efficiency. At the same time, the lightning protection mechanism effectively protects the equipment from lightning damage, ensuring stable operation of the system and further improving the reliability and service life of the power generation system.

[0025] The cleaning mechanism, lightning protection mechanism and solar power generation system are integrated into one, with a compact structure and reasonable layout. The arrangement of the centralized control box 4 and the battery 5 makes the collection, storage and distribution of electric energy more efficient, thus improving the operating efficiency and stability of the entire system.

[0026] This solution is suitable for solar photovoltaic power generation systems, especially those installed outdoors and susceptible to lightning strikes and dust contamination. It effectively solves the problems of surface cleaning and lightning protection for solar panels, improving power generation efficiency and equipment safety, and has broad application prospects.

[0027] In a further preferred embodiment of the present invention, the rubber strip 10 is connected to the scraper strip 9 by mortise and tenon joints so that the rubber strip 10 can be pulled out of the scraper strip 9, and a strip changing opening 13 is provided on each of the two side baffles 6. The two strip changing openings 13 are located on the same straight line, and the shape of the strip changing opening 13 is consistent with the cross-section of the rubber strip 10, so that the rubber strip 10 can be pulled out or entered through the strip changing opening 13.

[0028] In this embodiment, the rubber strip 10 is connected to the scraper strip 9 using a mortise and tenon joint. This connection allows the rubber strip 10 to be easily removed from the scraper strip 9. To facilitate replacement of the rubber strip 10, both side panels 6 are provided with strip replacement openings 13, and the two strip replacement openings 13 are located on the same straight line. The shape of the strip replacement openings 13 is consistent with the cross-section of the rubber strip 10, ensuring that the rubber strip 10 can be smoothly removed or inserted through the strip replacement openings 13. When the rubber strip 10 needs to be replaced, the operator can easily remove the old rubber strip 10 through the strip replacement openings 13 and insert the new rubber strip 10 to complete the replacement operation.

[0029] In a further preferred embodiment of the present invention, ear plates 11 are fixedly installed on the top of the two side baffles 6, and water spray pipes 12 are fixedly installed on the two ear plates 11. The water spray pipes 12 are externally connected to a water pump for spraying the cleaning solution onto the upper surface of the solar panel 3.

[0030] In this embodiment, ear plates 11 are fixedly mounted on the tops of both side panels 6, and water spray pipes 12 are fixedly mounted on these ear plates 11. Water spray pipes 12 are connected to an external pumping device and are used to spray cleaning solution onto the upper surface of the solar panels 3. During the cleaning process, the water spray pipes 12 evenly spray the cleaning solution onto the surface of the solar panels 3. The rubber strips 10 then scrape away the sprayed cleaning solution and surface impurities through the sliding action of the scraping strips 9, achieving efficient cleaning of the solar panels 3.

[0031] The water spray pipe 12 can evenly spray the cleaning solution on the surface of the solar panel 3, so that impurities are fully in contact with the cleaning solution, softening dust and dirt, making them easier to be scraped off by the rubber strip 10, significantly improving the cleaning effect and efficiency.

[0032] By spraying the cleaning solution, not only ordinary dust can be removed, but also some stubborn stains such as bird droppings, oil stains, etc. can be effectively removed, further ensuring the surface cleanliness of the solar panel 3 and ensuring its good photoelectric conversion efficiency.

[0033] The water spray pipe 12 works in conjunction with the cleaning mechanism to automate the cleaning process. The combination of water spraying and scraping action reduces manual intervention, reduces maintenance costs, and improves the stability and consistency of cleaning.

[0034] In a further preferred embodiment of the present invention, the lightning protection mechanism includes an assembly seat 14, a lightning receiving component, a lightning peak monitoring box 15, a down conductor 16 and a grounding rod 17. The assembly seat 14 is provided on the support frame 2, the lightning receiving component is installed on the assembly seat 14, and the lightning receiving component is located on one side of the mounting frame 1 and can extend upward for receiving lightning. The lightning peak monitoring box 15 is fixedly installed on the support frame 2, the down conductor 16 is connected to the lightning receiving component and the lightning peak monitoring box 15, the grounding rod 17 is connected to the bottom end of the down conductor 16, and the grounding rod 17 is connected to the ground for conducting lightning to the ground.

[0035] In the present embodiment, the design of the lightning protection mechanism includes an assembly base 14, a lightning receiving assembly, a lightning peak monitoring box 15, a down conductor 16 and a grounding rod 17. The assembly base 14 is fixedly mounted on the support frame 2, and the lightning receiving assembly is mounted on the assembly base 14 and can extend upward to one side of the mounting frame 1 for receiving lightning. The lightning peak monitoring box 15 is also fixedly mounted on the support frame 2 for monitoring the peak current of lightning. The down conductor 16 connects the lightning receiving assembly to the lightning peak monitoring box 15, and the grounding rod 17 is connected to the bottom end of the down conductor 16 and inserted into the ground for safely conducting the lightning current into the earth, thereby protecting the solar photovoltaic power generation system from damage caused by lightning strikes.

[0036] Through the cooperation of the lightning conductor assembly and the grounding rod 17, lightning can be effectively guided and directed into the ground, preventing lightning from directly hitting the solar photovoltaic power generation equipment, thereby significantly reducing the risk of equipment damage due to lightning strikes.

[0037] The lightning peak monitoring box 15 can monitor the peak current of lightning in real time, providing the system with lightning strike data, which is convenient for analyzing lightning strike conditions and taking corresponding protective measures. At the same time, the monitoring data can be used for early warning and preventive preparation in advance.

[0038] The core component of the lightning peak monitoring box 15 is typically a current sensor (such as a Rogowski coil or Hall effect sensor). When lightning current passes through the down conductor 16, it generates a magnetic field around it. The current sensor detects the magnitude of the lightning current by sensing changes in this magnetic field.

[0039] The Lightning Peak Monitoring Box 15 detects lightning currents through electromagnetic induction. Signal processing circuitry amplifies and processes the induced signals, allowing real-time monitoring and recording of lightning current peaks. Through data recording and transmission capabilities, the box can send this data to a monitoring center. It also provides protection and alarm functions, ensuring the safe operation of solar photovoltaic systems during periods of lightning activity.

The porcelain sleeve 18 is detachably mounted on the assembly seat 14, the conductive core rod 19 is fixedly embedded in the porcelain sleeve 18, the conductive core rod 19 is connected to the top of the down conductor 16, the lightning rod 20 is fixedly mounted on the top of the conductive core rod 19, the conductive tube rod 21 is fixedly mounted on the top of the lightning rod 20, the conductive extension rod 22 is telescopically mounted in the conductive tube rod 21, the conductive extension rod 22 extends from the top of the conductive tube rod 21, the voltage equalizing ring 23 is fixedly mounted on the top of the conductive extension rod 22, and the lightning rod 24 is fixedly mounted on the top of the voltage equalizing ring 23.

[0041] In this embodiment, the design of the lightning rod assembly includes a porcelain sleeve 18, a conductive core rod 19, a lightning rod 20, a conductive tube rod 21, a conductive extension rod 22, a voltage equalizing ring 23 and a lightning rod 24. The porcelain sleeve 18 is detachably mounted on the assembly seat 14, and the conductive core rod 19 is fixedly embedded in the porcelain sleeve 18 and connected to the top of the down conductor 16.

The conductive tube rod 21 is fixedly mounted on the top of the lightning rod 20, and the conductive extension rod 22 is telescopically mounted in the conductive tube rod 21 and extends from its top. The voltage equalizing ring 23 is fixedly mounted on the top of the conductive extension rod 22, and the lightning rod 24 is fixedly mounted on the top of the voltage equalizing ring 23. Through this structure, the lightning rod assembly can effectively receive lightning and conduct it safely to the ground.

[0042] The lightning receptor 20 and lightning rod 24, located at the top of the lightning conductor assembly, effectively receive lightning. The conductive core rod 19, conductive tube rod 21, and conductive extension rod 22 form an efficient conductive path, ensuring that lightning current is quickly and safely conducted to the down conductor 16 and ultimately to the ground, protecting the solar photovoltaic power generation system from damage caused by lightning strikes.

[0043] The grading ring 23 effectively balances the potential distribution of lightning current during its conduction, reducing arcing caused by potential differences and further improving system safety and reliability. It also reduces the inductive effects of lightning current on surrounding equipment, minimizing the risk of secondary damage.

[0044] The retractable design of the conductive extension rod 22 allows the height of the lightning protection assembly to be flexibly adjusted according to actual needs, making it suitable for solar photovoltaic power generation equipment of different heights. In addition, the removable design of the porcelain sleeve 18 facilitates maintenance and replacement of the lightning protection assembly, improving the maintainability of the system.

[0045] In a further preferred embodiment of the present invention, a through hole is provided on the assembly seat 14, and the porcelain sleeve 18 is inserted into the through hole. A limiting sleeve 25 is fixed on the porcelain sleeve 18, and the limiting sleeve 25 is placed on the top of the assembly seat 14 and fixed with a positioning bolt 26 to connect the porcelain sleeve 18 to the assembly seat 14.

[0046] In this embodiment, the assembly base 14 is provided with a through-hole into which the porcelain sleeve 18 is inserted. To ensure stable installation of the porcelain sleeve 18 on the assembly base 14, a retaining sleeve 25 is fixed to the porcelain sleeve 18. The retaining sleeve 25 is placed on top of the assembly base 14 and secured with a positioning bolt 26, thereby achieving a secure connection between the porcelain sleeve 18 and the assembly base 14. This connection method not only ensures the installation accuracy of the porcelain sleeve 18 but also facilitates installation and removal operations.

[0047] This connection method adopts a detachable design, which facilitates the installation and removal of the porcelain sleeve 18. When the lightning connection component needs to be maintained or replaced, the porcelain sleeve 18 can be quickly removed, which improves maintenance efficiency and reduces maintenance costs.

[0048] In a further preferred embodiment of the present invention, the bottom end of the conductive core rod 19 and the top end of the grounding rod 17 are fixedly installed with connecting screws 27, and the two connecting screws 27 are both slidably sleeved with conductive joints 28 and fixed with locking nuts 29. The two conductive joints 28 are respectively fixedly connected to the two ends of the down conductor 16.

[0049] In this embodiment, connecting screws 27 are fixedly mounted on the bottom end of the conductive core rod 19 and the top end of the grounding rod 17. Conductive connectors 28 are slidably mounted on each of the two connecting screws 27 and secured by lock nuts 29. The conductive connectors 28 are fixedly connected to both ends of the down conductor 16, thereby establishing reliable electrical connections between the conductive core rod 19 and the down conductor 16, and between the down conductor 16 and the grounding rod 17. This connection ensures that lightning current can be smoothly conducted to the ground through the conductive core rod 19, the down conductor 16, and the grounding rod 17.

[0050] In a further preferred embodiment of the present invention, the installation frame 1 is arranged at an angle, and the lightning protection assembly is located on a high side of the installation frame 1.

[0051] In this embodiment, the mounting frame 1 is tilted, with the lightning protection assembly located on the higher side of the mounting frame 1. This design allows the lightning protection assembly to more effectively receive lightning, as lightning tends to strike higher objects. By locating the lightning protection assembly on the higher side of the mounting frame 1, its lightning protection range is maximized, ensuring that lightning is safely directed to the grounding system, thereby protecting the solar panels 3 and other equipment from damage caused by lightning strikes.

[0052] In a further preferred embodiment of the present invention, the side baffles 6 and the driving screw 8 are arranged along the inclined surface of the mounting frame 1 so that the scraper strip 9 and the rubber strip 10 move along the inclined surface of the mounting frame 1 .

[0053] In this embodiment, the side guards 6 and drive screw 8 are positioned along the inclined surface of the mounting frame 1. This design enables the scraper bar 9 and rubber strip 10 to move along the inclined surface of the mounting frame 1, thereby cleaning the surface of the solar panel 3. Specifically, the rotation of the drive screw 8 causes the scraper bar 9 to slide along the side guard 6, while the rubber strip 10 adheres closely to the surface of the solar panel 3. As the scraper bar 9 moves, the rubber strip 10 effectively scrapes away dust and impurities from the panel's surface.

[0054] In a further preferred embodiment of the present invention, the drainage position of the water spray pipe 12 is set in the direction of the solar panel 3, and one end of the water spray pipe 12 is provided with a water inlet connector for connecting to an external water pump component.

[0055] In this embodiment, the water pipe 12 is designed to drain toward the solar panel 3, ensuring that the cleaning solution is sprayed directly onto the panel's surface. One end of the water pipe 12 is equipped with a water inlet connector for connecting to an external water pump assembly. The pressure provided by the pump assembly pumps the cleaning solution into the water pipe 12 and is evenly sprayed onto the surface of the solar panel 3 through the nozzle. This design ensures that the cleaning solution effectively covers the entire panel surface, supporting the subsequent cleaning action of the scraper bar 9 and rubber strip 10.

[0061] In this embodiment, a driven shaft 40 is rotatably mounted on the top of the assembly box 30. The top end of the driven shaft 40 extends to one end of the drive screw 8. Both the driven shaft 40 and the support spindle 31 are fixedly mounted with a bevel gear 1 41.

[0062] The meshing of bevel gear 1 41 and bevel gear 2 42 creates a linkage between the support spindle 31, the driven shaft 40, and the drive screw 8. This design allows the cleaning mechanism (scraper 9 and rubber strip 10) and the lightning catcher to rotate synchronously, ensuring that the lightning catcher remains in the optimal position during the cleaning process, improving the overall efficiency and reliability of the system.

This shell covers the exterior of the driven shaft 40, bevel gear 1 41, and one end of the drive screw 8. This design, through the protective shell 43, provides an enclosed, protected space for these critical transmission components, preventing direct contact and interference from external environmental factors (such as dust, rain, and debris), thereby ensuring the normal operation of the transmission system.

[0065] In another embodiment of the present invention, the conductive tube rod 21 is provided with a lifting drive mechanism for driving the conductive extension rod 22 to lift and lower. The lifting drive mechanism includes a connecting sleeve 44 fixedly sleeved on the conductive tube rod 21, and component assembly plates 45 are fixedly installed on opposite sides of the connecting sleeve 44. The two component assembly plates 45 are respectively located on both sides of the conductive extension rod 22, and a tooth groove 46 is provided on one side of the conductive extension rod 22. A stabilizing shaft 47 and a lifting drive shaft 48 are rotatably installed on the two component assembly plates 45. The lifting drive shaft 48 is located on the side of the conductive extension rod 22 having the tooth groove 46. The stabilizing shaft 47 and the lifting drive shaft 48 are fixedly installed on the two component assembly plates 45. 7 is located on the other side, the stabilizing shaft 47 is in contact with the side of the conductive extension rod 22, so that the conductive extension rod 22 is stable when it is lifted and lowered, and a driving gear 49 is fixedly provided on the lifting drive shaft 48, and the driving gear 49 is engaged with the tooth groove 46, so that the lifting drive shaft 48 and the driving gear 49 drive the conductive extension rod 22 to be lifted and lowered when the lifting drive shaft 48 and the driving gear 49 rotate. Two width limiting rings 50 are fixedly provided on the stabilizing shaft 47, and the two width limiting rings 50 are respectively located on both sides of the conductive extension rod 22. The spacing between the two width limiting rings 50 is just adapted to the position where the conductive extension rod 22 contacts. The two component assembly plates 45 are also rotatably installed with power The transmission short shaft 51, the lifting drive shaft 48 and the power transmission short shaft 51 are fixedly installed with a sprocket 2 52, and the two sprockets 2 52 are sleeved with the same chain 2 53, so that when the power transmission short shaft 51 rotates, the lifting drive shaft 48 is driven to rotate synchronously, and the porcelain sleeve 18 and the conductive tube rod 21 are fixedly installed with a shaft seat plate 54, and the shaft seat plate 54 is rotatably installed with a power transmission long shaft 55, and the top of the power transmission long shaft 55 extends to the bottom of the power transmission short shaft 51, and the top of the power transmission long shaft 55 and the power transmission short shaft 51 are fixedly sleeved with a bevel gear 3 56, and the two bevel gears 3 5 6 are meshed with each other so that when the power transmission long shaft 55 rotates, the power transmission short shaft 51 is driven to rotate synchronously. The assembly box 30 is located on one side of the support main shaft 31 and is fixedly installed with a conical gear ring 57. The conical gear ring 57 is arranged around the support main shaft 31 as the center of the circle. The bottom end of the power transmission long shaft 55 is fixedly installed with a driven bevel gear 58. The driven bevel gear 58 is meshed with the conical gear ring 57 so that when the support main shaft 31 drives the assembly seat 14 and the components above it to rotate, the driven bevel gear 58 on the power transmission long shaft 55 rolls along the conical gear ring 57, so that the power transmission long shaft 55 drives the power transmission short shaft 51 to rotate synchronously.

[0066] In this embodiment, the conductive tube rod 21 is provided with a lifting drive mechanism for driving the conductive extension rod 22 to move upward and downward. This mechanism includes a connecting sleeve 44 fixedly mounted on the conductive tube rod 21, with assembly plates 45 fixedly mounted on either side of the connecting sleeve 44. A tooth groove 46 is formed on one side of the conductive extension rod 22, and a stabilizing shaft 47 and a lifting drive shaft 48 are rotatably mounted on the assembly plate 45. A drive gear 49 on the lifting drive shaft 48 engages with the tooth groove 46 to drive the conductive extension rod 22 upward and downward. The stabilizing shaft 47 contacts the side of the conductive extension rod 22 to ensure stability during the lifting process. Two width-limiting rings 50 are fixedly mounted on the stabilizing shaft 47 to limit lateral movement of the conductive extension rod 22. A power transmission short shaft 51 is also rotatably mounted on the assembly plate 45. This short shaft 51 is connected to the lifting drive shaft 48 via a second sprocket 52 and a second chain 53 to achieve power transmission. The power transmission long shaft 55 is mounted on the porcelain sleeve 18 and the conductive cylindrical rod 21 via a shaft base plate 54. Its top end meshes with the power transmission short shaft 51 via a bevel gear 3 56, while a driven bevel gear 58 at its bottom end meshes with a bevel gear ring 57 on the assembly box 30. When the support spindle 31 drives the assembly base 14 to rotate, the driven bevel gear 58 rolls along the bevel gear ring 57, driving the power transmission long shaft 55 to rotate. This, in turn, drives the power transmission short shaft 51 and the lifting drive shaft 48 to rotate synchronously, achieving the lifting and lowering control of the conductive extension rod 22.

[0067] Through the lifting drive mechanism, especially the engagement of the driving gear 49 with the tooth groove 46, the lifting and lowering action of the conductive extension rod 22 can be accurately controlled to ensure its stability and reliability under different height requirements.

[0068] The design of the stabilizing shaft 47 and the width limiting ring 50 effectively limits the lateral movement of the conductive extension rod 22 during the lifting process, thereby improving the stability and safety of the system. At the same time, the power transmission method of the sprocket 52 and the chain 53 ensures the smoothness of power transmission.

[0069] The coordination of the power transmission long shaft 55, the power transmission short shaft 51, the driven bevel gear 58, and the bevel gear ring 57 enables coordinated movement with the support main shaft 31. This design allows the lifting and lowering of the conductive extension rod 22 to be synchronized with the rotation of the entire lightning protection mechanism, improving the system's integration and coordination.

[0070] In this solution, key components of the lift drive mechanism are manufactured from high-performance insulating materials, such as glass fiber reinforced plastic (GFRP) or other materials for the connecting sleeve 44 and the component assembly plate 45, and polyetheretherketone (PEEK) or other materials for the sprocket 52 and the width-limiting ring 50. The surface of the lift drive shaft 48 is coated with an insulating coating to provide additional insulation protection. Furthermore, a metal shielding cover is installed on the outside of the lift drive mechanism and can be connected to the grounding system via a grounding wire to ensure that electromagnetic interference generated by lightning strikes is effectively dissipated. Through these measures, the lift drive mechanism can maintain normal operation in a lightning strike environment while ensuring the safety of equipment and personnel.

[0071] High-performance insulating materials and insulating coatings are used to ensure that the lifting drive mechanism is non-conductive in a lightning environment, avoiding damage to equipment and personnel caused by lightning current.

[0072] The selected materials have high strength and good mechanical properties, which can withstand the mechanical stress of the lifting drive mechanism and ensure the stability and reliability of the system.

[0073] In another embodiment of the present invention, the assembly box 30 is provided with a through opening on the side where the slide plate 34 slides out, and an extension receiving cover 59 is fixedly installed on this side to allow the slide plate 34 to slide in.

[0074] In this embodiment, the assembly box 30 has an opening on the side through which the slide 34 slides out, and an extension storage cover 59 is fixedly mounted on this side. The opening allows the slide 34 to slide smoothly in and out of the assembly box 30 as it slides on the guide rails 33, while the extension storage cover 59 provides additional storage space for the slide 34. When the slide 34 slides outside the assembly box 30, the extension storage cover 59 can accommodate the slide 34, properly protecting it from the external environment when not in use.

[0075] To sum up, compared with related technologies, this device integrates the cleaning mechanism, lightning protection mechanism and solar power generation system into one, with a compact structure and reasonable layout, which effectively solves the problems of solar panel surface cleaning and lightning protection, and improves power generation efficiency and equipment safety.
