Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel technology, and particularly relates to a self-cleaning photovoltaic panel with individually replaceable cleaning components. Background Technology

[0002] With the widespread application of photovoltaic (PV) power generation technology globally, maintaining the high efficiency of PV panel modules is crucial. Dust, snow, bird droppings, and other contaminants on the surface of PV panels can severely impede sunlight penetration, leading to a significant decrease in photoelectric conversion efficiency. Therefore, regularly and effectively cleaning the surface of PV panels is a key step in ensuring their high-efficiency power generation.

[0003] Traditional cleaning methods primarily rely on manual washing or rinsing, which is not only inefficient and costly, but also poses safety risks when operating at heights or over large arrays. To address this issue, various automated cleaning devices have emerged on the market, such as automated cleaning robots or track-based cleaning systems installed on photovoltaic panel arrays. These systems typically include cleaning components such as brushes or scrapers that can reciprocate along tracks under motor drive, sweeping or scraping the surface of the photovoltaic panels.

[0004] However, existing automated cleaning devices still have the following significant drawbacks: Scrapers, usually made of rubber or silicone strips, are key components for removing surface water stains and stubborn dirt. However, they are prone to aging, deformation, and even breakage due to long-term friction with the photovoltaic panel surface and exposure to harsh outdoor environments.

[0005] During the cleaning process, if a scraper is partially damaged, the damaged point will continue to contact the photovoltaic panel surface during subsequent cleaning cycles. This contact not only reduces the cleaning effect, but the damaged scraper edge may also more violently scrape or even damage the photovoltaic panel surface. At the same time, it will cause strong vibrations to the scraped module or the entire device, accelerating the aging of other components. In severe cases, it may lead to equipment shutdown. With existing technology, after the damage is detected, users can often only manually inspect and replace the entire scraper after the equipment reports an error and shuts down. This results in long maintenance cycles and significant power generation losses.

[0006] Therefore, there is an urgent need to design a self-cleaning photovoltaic panel with individually replaceable cleaning components to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a self-cleaning photovoltaic panel with replaceable cleaning components, which has the advantage of automatically replacing the scraper after the scraper is damaged, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides a specific technical solution for a self-cleaning photovoltaic panel with individually replaceable cleaning components as follows: A self-cleaning photovoltaic panel with replaceable cleaning components includes brackets at both ends of the photovoltaic panel, with a cleaning component and a scraping component mounted on the brackets. The cleaning component and the scraping component are connected and can slide along the brackets to clean the photovoltaic panel and scrape away water. The scraping assembly includes multiple scrapers. When the scraping assembly is reset, it rotates relative to the support, causing the scrapers to lose contact with the photovoltaic panel. When the scraping assembly is damaged, the scrapers vibrate when they come into contact with the photovoltaic panel, causing the scraping assembly to rotate relative to the support, thus swapping the positions of the damaged scraper and the unused scraper.

[0009] Furthermore, the scraping assembly also includes a support cover, inside which a connecting block is fixedly connected. A rotating rod is rotatably connected to the connecting block, and a rotating roller is fixedly connected to the rotating rod. The rotating roller is connected to multiple scrapers, and the rotating roller can drive the multiple scrapers to rotate relative to the support about the rotating rod as the axis.

[0010] Furthermore, a sliding rod is slidably connected to the rotating rod, and a gear is fixedly connected to the sliding rod. A first rack, a second rack, and a third rack are fixedly connected to both ends of the bracket, respectively. The first rack is located in the cleaning direction of the scraping component, and the second and third racks are located in the reset direction of the scraping component. The first rack and the second rack are not on the same horizontal line. When the scraper is reset, the gear meshes with the first rack, and the gear drives the sliding rod and the rotating rod to rotate, so that the scraper is no longer in contact with the photovoltaic panel when it is reset; When the scraping component is undamaged and moves in the cleaning direction, the gear meshes with the second rack, and the gear drives the sliding rod and the rotating rod to rotate, so that the scraper used comes into contact with the photovoltaic panel. When the scraping component is damaged and moves in the cleaning direction, the gear meshes with the second and third racks, and the gear drives the sliding rod and the rotating rod to rotate, so that the position of the damaged scraper is interchanged with that of the unused scraper.

[0011] Furthermore, the first rack has the same number of teeth as the second rack, and the third rack has twice the number of teeth as either the first rack or the second rack.

[0012] Furthermore, a sliding groove is provided on the bracket, and the third rack can slide along the sliding groove. When the scraping component is not damaged, the third rack is separated from the second rack, and when the scraping component is damaged, the third rack is connected to the second rack.

[0013] Furthermore, a first wedge and a second wedge are fixedly connected to both ends of the bracket, the first wedge and the first rack are located at the same end of the bracket, the second wedge and the second rack are located at the same end of the bracket, and a stop plate is fixedly connected to the sliding rod. The stop plate can change the position of the gear through the first wedge and the second wedge. When the abutting plate abuts against the first wedge, the abutting plate drives the gear to slide towards the end closer to the rotating rod until the gear slides to the same horizontal line as the first rack; When the abutment plate abuts against the second wedge, the abutment plate drives the gear to slide away from the rotating rod until the gear slides to the same horizontal line as the second rack.

[0014] Furthermore, the scraping component is equipped with a self-locking component. When the scraping component is above the photovoltaic panel, it is locked and cannot be rotated by the self-locking component. When the scraping component is not above the photovoltaic panel, the self-locking component is unlocked, and the scraping component can rotate.

[0015] Furthermore, a locking block is fixedly connected to the rotating rod, and multiple locking slots are opened on the locking block. A connecting frame is fixedly connected to the connecting block, and a locking block is slidably connected to the connecting frame. When the locking block is engaged in the locking slot, the locking block cannot rotate. When the locking block is separated from the locking slot, the locking block can drive the rotating rod to rotate.

[0016] Furthermore, two mating blocks are fixedly connected to both ends of the bracket, and a connecting rod is fixedly connected to the locking block. The connecting rod has a mating groove. After the mating block abuts against the mating groove, the connecting rod drives the locking block to slide away from the locking block until the locking block separates from the locking groove.

[0017] Furthermore, a spring is fitted on the connecting rod, with both ends of the spring fixedly connected to the locking block and the connecting frame, respectively, so that after the mating block separates from the mating groove, the spring force is released, and the locking block engages with the locking groove.

[0018] This invention has the following advantages: When the scraper is damaged and causes abnormal vibration, the system automatically rotates the scraping component to move the damaged scraper out of the working position and replace it with a good spare scraper, realizing self-repair without stopping the machine and avoiding downtime losses. Moreover, when resetting, the scraping component rotates and the scraper is removed from the photovoltaic panel surface, completely eliminating the increased energy consumption, aggravated wear and dirt re-carrying caused by resetting friction, and solving the resetting interference problem.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0022] The following is a reference to the appendix. Figure 1 To be continued Figure 8 The present invention describes a self-cleaning photovoltaic panel 1 with replaceable cleaning components, comprising a bracket 11 disposed at both ends of the photovoltaic panel 1, a cleaning component disposed on the bracket 11, the cleaning component comprising a sweeping component 3 and a scraping component 2, the sweeping component 3 and the scraping component 2 being connected, the sweeping component 3 and the scraping component 2 being slidable along the bracket 11 to sweep the photovoltaic panel 1 and scrape off water, the scraping component 2 comprising a plurality of scrapers 24.

[0023] The system also includes a drive assembly 4, which drives the sweeping assembly 3 and the scraping assembly 2 to slide along the bracket 11. Preferably, the drive assembly 4 includes a support block 41 fixedly connected to both ends of each bracket 11. A drive disk 42 is rotatably connected to the support block 41 via a rotating shaft. Two drive disks 42 located on the same side are connected by a drive belt 43. A fixing block 44 is fixedly connected to the drive belt 43 and is connected to the sweeping assembly 3 and the scraping assembly 2 via the fixing block 44. A motor is also fixedly connected to the bracket 11. The output end of the motor is fixedly connected to the rotating shaft so as to drive the drive disk 42 to rotate. In other embodiments of the present invention, the sweeping assembly 3 and the scraping assembly 2 can also be driven to slide along the bracket 11 by other drive structures, such as an electric push rod, to push the sweeping assembly 3 and the scraping assembly 2 to slide along the bracket 11.

[0024] Currently, various automated cleaning devices have emerged on the market, such as automated cleaning robots or track-based cleaning systems installed on the photovoltaic panel array 1. These systems typically include cleaning components such as brushes or scrapers 24, which can reciprocate along a track under motor drive to sweep or scrape the surface of the photovoltaic panel 1.

[0025] However, existing automated cleaning devices still have the following significant drawbacks: The scraper 24 is usually a rubber or silicone strip and is a key component for removing surface water stains and stubborn dirt. However, it is prone to aging, deformation or even breakage due to long-term friction with the surface of the photovoltaic panel 1 and exposure to harsh outdoor environments.

[0026] During the cleaning process, if a scraper 24 is partially damaged, the damaged point will continue to contact the surface of the photovoltaic panel 1 in subsequent cleaning cycles. This contact not only reduces the cleaning effect, but the edge of the damaged scraper 24 may also scrape or even damage the surface of the photovoltaic panel 1 more violently. At the same time, it will cause strong vibration of the scraping module 2 or the entire device, accelerate the aging of other components, and may even cause the equipment to shut down in severe cases. In the current technology, after the damage is detected, users can often only manually inspect and replace the entire scraper 24 after the equipment reports an error and shuts down. The maintenance cycle is long and the power generation loss is large.

[0027] Therefore, when the scraping assembly 2 is damaged, the scraper 24 vibrates when it comes into contact with the photovoltaic panel 1. The scraping assembly 2 rotates relative to the bracket 11, causing the damaged scraper 24 to be swapped with the unused scraper 24. When the scraper 24 is damaged and causes abnormal vibration, the system automatically rotates the scraping assembly 2 to move the damaged scraper 24 out of the working position and replace it with a good spare scraper 24, thus achieving self-repair without stopping the machine and avoiding downtime losses.

[0028] After completing a cleaning cycle, the cleaning component needs to return to its starting position. During the reset process, if the scraper 24 remains in contact with the surface of the photovoltaic panel 1, unnecessary reverse friction will occur, causing not only additional wear on the scraper 24 and energy consumption, but also potentially bringing back dirt that has not been completely removed to the cleaned area, or even scratching the surface of the photovoltaic panel 1.

[0029] Therefore, when the photovoltaic panel 1 is reset, the scraping component 2 rotates relative to the bracket 11, so that the scraper 24 is no longer in contact with the photovoltaic panel 1. This causes the scraping component 2 to rotate during reset, and the scraper 24 to detach from the surface of the photovoltaic panel 1, thus completely eliminating the increased energy consumption, aggravated wear, and dirt re-carrying caused by reset friction, and solving the reset interference problem.

[0030] The scraping assembly 2 also includes a support cover 21, which protects the scraper 24, reduces sand and rain erosion, and improves outdoor durability. A connecting block 22 is fixedly connected inside the support cover 21, and a rotating rod 25 is rotatably connected to the connecting block 22. A rotating roller 23 is fixedly connected to the rotating rod 25. The rotating roller 23 is connected to multiple scrapers 24. The rotating roller 23 can drive multiple scrapers 24 to rotate relative to the bracket 11 around the rotating rod 25 as the axis. All scrapers 24 are driven synchronously by the rotating roller 23 to ensure that the switching action angle is consistent and without deviation.

[0031] A sliding rod 28 is slidably connected to the rotating rod 25, and a gear 26 is fixedly connected to the sliding rod 28. A first rack 12, a second rack 14, and a third rack 15 are fixedly connected to both ends of the bracket 11, respectively. The first rack 12 is located in the cleaning direction of the scraping component 2, and the second rack 14 and the third rack 15 are located in the reset direction of the scraping component 2. The first rack 12 and the second rack 14 are not on the same horizontal line. When the scraping assembly 2 is reset, the gear 26 meshes with the first rack 12, and the gear 26 drives the sliding rod 28 and the rotating rod 25 to rotate, so that the scraper 24 cancels contact with the photovoltaic panel 1 when it is reset; When the scraping assembly 2 is undamaged and moves in the cleaning direction, the gear 26 meshes with the second rack 14, and the gear 26 drives the sliding rod 28 and the rotating rod 25 to rotate, so that the scraper 24 used comes into contact with the photovoltaic panel 1. When the scraping assembly 2 is damaged and moves in the cleaning direction, the gear 26 meshes with the second rack 14 and the third rack 15. The gear 26 drives the sliding rod 28 and the rotating rod 25 to rotate, so that the position of the damaged scraper 24 is interchanged with that of the unused scraper 24.

[0032] Specifically, a keyway is provided on the rotating rod 25, and a spline 29 is fixedly connected to the sliding rod 28. The sliding rod 28 is slidably connected to the keyway through the spline 29, so that when the rotating rod 25 rotates, the sliding rod 28 rotates synchronously and can slide relative to the rotating rod 25.

[0033] Preferably, there are two scrapers 24, and the two scrapers 24 are 180 degrees apart. When the gear 26 meshes with the first rack 12, the gear 26 drives the scraper 24 to rotate 90 degrees in the forward direction, so that the scraper 24 cancels contact with the photovoltaic panel 1 when it resets. When the scraper 24 is not damaged and moves in the cleaning direction, the gear 26 meshes with the second rack 14, and the gear 26 drives the scraper 24 to rotate 90 degrees in the reverse direction, so that the used scraper 24 contacts the photovoltaic panel 1 and is scraped by the previously used scraper 24. When the scraper 24 is damaged and moves in the cleaning direction, the gear 26 meshes with the second rack 14 and the third rack 15, and the gear 26 drives the scraper 24 to rotate 270 degrees in the reverse direction, so that the positions of the damaged scraper 24 and the unused scraper 24 are interchanged. In the subsequent process, a brand new scraper 24 is used for scraping. In other embodiments of the present invention, the number of scrapers 24 may be greater than two.

[0034] Since the environment of photovoltaic panel 1 is mostly harsh, the above structure does not rely on electronic sensors, but only responds to working conditions through the meshing of gear 26 with different racks, thus adapting to harsh environments such as high and low temperatures and humidity.

[0035] The number of teeth on the first rack 12 is the same as the number of teeth on the second rack 14, so that the rotation angle is the same when the scraping component 2 is reset and when the scraping component 2 is undamaged and moves in the cleaning direction. The number of teeth on the third rack 15 is twice the number of teeth on the first rack 12 or the second rack 14.

[0036] The bracket 11 has a sliding groove, and the third rack 15 can slide along the sliding groove. When the scraping component 2 is not damaged, the third rack 15 is separated from the second rack 14. When the scraping component 2 is damaged, the third rack 15 is connected to the second rack 14. Specifically, the bracket 11 is provided with an electric push rod. The fixed end of the electric push rod is fixedly connected to the bracket 11, and the output end of the electric push rod is connected to the third rack 15. The scraping component 2 is provided with a vibration sensor to detect the vibration signal generated when the scraper 24 is damaged. When the vibration signal exceeds the set threshold, the controller drives the electric push rod to push the third rack 15, so that the third rack 15 is connected to the second rack 14, so that the scraper 24 is switched when the gear 26 meshes with the second rack 14 and the third rack 15.

[0037] The first wedge 13 and the second wedge 16 are fixedly connected to both ends of the bracket 11, respectively. The first wedge 13 and the first rack 12 are located at the same end of the bracket 11, and the second wedge 16 and the second rack 14 are located at the same end of the bracket 11. A stop plate 27 is fixedly connected to the sliding rod 28. The stop plate 27 can change the position of the gear 26 through the first wedge 13 and the second wedge 16. When the abutment plate 27 abuts against the first wedge block 13, the abutment plate 27 drives the gear 26 to slide towards the end closer to the rotating rod 25 until the gear 26 slides to the same horizontal line as the first rack 12. When the abutment 27 abuts against the second wedge 16, the abutment 27 drives the gear 26 to slide away from the rotating rod 25 until the gear 26 slides to the same horizontal line as the second rack 14.

[0038] The scraping assembly 2 is equipped with a self-locking assembly 5. When the scraping assembly 2 is above the photovoltaic panel 1, the scraping assembly 2 is locked by the self-locking assembly 5 and cannot be rotated. When scraping water, the scraping assembly 2 is locked to prevent the scraper blade 24 from shifting due to vibration caused by the rotation of the scraping assembly 2, thus ensuring uniform cleaning pressure. When resetting, the scraping assembly 2 is locked to prevent accidental rotation that would cause the scraper blade 24 to droop and contact the surface. When the scraping assembly 2 is not above the photovoltaic panel 1, the self-locking assembly 5 is unlocked, and the scraping assembly 2 can rotate, reserving a degree of freedom for the rotation of the scraper blade 24.

[0039] A locking block 51 is fixedly connected to the rotating rod 25. The locking block 51 has multiple locking grooves 511. A connecting frame 52 is fixedly connected to the connecting block 22. A locking block 54 is slidably connected to the connecting frame 52. When the locking block 54 is engaged in the locking groove 511, the locking block 51 cannot rotate. When the locking block 54 is separated from the locking groove 511, the locking block 51 can drive the rotating rod 25 to rotate. Specifically, two mating blocks 17 are fixedly connected to both ends of the bracket 11. A connecting rod 53 is fixedly connected to the locking block 54. A mating groove 531 is opened on the connecting rod 53. After the mating block 17 abuts against the mating groove 531, the connecting rod 53 drives the locking block 54 to slide away from the locking block 51 until the locking block 54 is separated from the locking groove 511.

[0040] Furthermore, a spring 55 is sleeved on the connecting rod 53, and the two ends of the spring 55 are fixedly connected to the locking block 54 and the connecting frame 52 respectively, so that after the mating block 17 separates from the mating groove 531, the elastic force of the spring 55 is released, and the locking block 54 engages with the locking groove 511.

[0041] It also includes a limiting block 56, which is fixedly connected to the connecting rod 53 and limits the sliding stroke of the connecting rod 53 by limiting the sliding stroke of the connecting rod 53.

[0042] Workflow: When the cleaning state is in progress and the scraping component 2 is located at the A-end starting position above the photovoltaic panel 1, the self-locking component 5 is activated. The locking block 54 is inserted into the locking groove 511 of the locking block 51 under the action of the spring 55, the rotating rod 25 is locked, the scraper 24 contacts the photovoltaic panel 1, and the abutment 27 is separated from the second wedge 16. The gear 26 and the second rack 14 are on the same horizontal line, but not engaged. Then the motor starts, and the drive disc 42 drives the sweeping component 3 and the scraping component 2 to move along the bracket 11 to the other end via the drive belt 43. The sweeping component 3 sweeps away the surface dust, and the scraper 24 scrapes away the residual water stains.

[0043] When the cleaning state is in progress and the scraping component 2 is located near the photovoltaic panel 1B end and the scraping component 2 is separated from the photovoltaic panel 1, the self-locking component 5 is unlocked first, the mating block 17 abuts against the mating groove 531, causing the locking block 54 to separate from the groove, and then the abutting plate 27 abuts against the first wedge block 13, causing the gear 26 to move to be on the same horizontal line as the first rack 12.

[0044] Then it enters the reset state. When the scraping component 2 is in the reset state and located near the photovoltaic panel 1B end and separated from the photovoltaic panel 1, the gear 26 first meshes with the first rack 12, causing the scraper 24 to rotate. The scraper 24 will not contact the photovoltaic panel 1 during the reset process. After the gear 26 has rotated, the mating block 17 separates from the mating groove 531, and the locking block 54 engages with the locking groove through the elastic force of the spring 55, locking the gear 26, and then resets.

[0045] When the scraping component 2 is in the reset state and is located near the photovoltaic panel 1A end and separated from the photovoltaic panel 1, the self-locking component 5 is unlocked first, the mating block 17 abuts against the mating groove 531, causing the locking block 54 to separate from the groove, and then the abutting plate 27 abuts against the second wedge block 16, causing the gear 26 to move to be on the same horizontal line as the second rack 14.

[0046] If the scraper 24 is not damaged, in the cleaning state and when the scraping component 2 is located near the photovoltaic panel 1A end and the scraping component 2 is separated from the photovoltaic panel 1, the gear 26 meshes with the second rack 14, causing the scraper 24 to rotate. The scraper 24 contacts the photovoltaic panel 1 during the cleaning process. After the gear 26 has rotated, the mating block 17 separates from the mating groove 531, and the locking block 54 is engaged with the locking groove 511 by the elastic force of the spring 55, thus locking the scraping component 2, and then cleaning continues.

[0047] If the scraper 24 is damaged, in the cleaning state and when the scraping component 2 is located near the photovoltaic panel 1A end and the scraping component 2 is separated from the photovoltaic panel 1, the gear 26 meshes with the second rack 14 and the third rack 15, so that the position of the damaged scraper 24 is interchanged with that of the unused scraper 24. After the gear 26 has rotated, the mating block 17 separates from the mating groove 531, and the locking block 54 is engaged with the locking groove 511 by the elastic force of the spring 55, thus locking the scraping component 2, and then cleaning is performed.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
