Description

Technical Field

[0001] This invention relates to the field of photovoltaic cleaning with brackets, and in particular to a flexible photovoltaic cleaning device with brackets. Background Technology

[0002] A flexible photovoltaic (PV) support structure is a large-span PV module support structure that is fixed at both ends, based on a tension structure system design, and uses cables as the module support components. Its structural system typically consists of a prestressed cable structure, a support system, an anchor system, and a damping vibration reduction system.

[0003] The main types include single-layer cable-stayed structures, double-layer cable truss structures, fish-belly cable truss structures, and tensioned structures. A single-layer cable-stayed structure consists of a main steel frame of beams and columns, and cable stays; a double-layer cable truss structure adds rigid struts to this structure; a fish-belly cable truss structure includes diagonal supports, columns, and other components, resembling the belly of a fish; and a tensioned structure includes a rigid upper chord, cables, and rigid struts. Between the columns or on the portal frame structure, a tensioning system applies pre-tension to the cables, taut them, and forms a stable bearing plane. Photovoltaic modules are then fixed to these cables using specialized clamps.

[0004] Regardless of the type of flexible photovoltaic support system, they all fundamentally use a tensioned structure to install and tension solar panels. While auxiliary support structures may be added, the load-bearing capacity of these tensioned structures is generally limited, making it inconvenient to install intelligent moving equipment when cleaning the solar panels. Furthermore, although the solar panels are laid in rows and columns, the tensioned structure is typically of limited length, resulting in isolation between sections. This makes it difficult for moving equipment to switch between sections. Additionally, due to the tensioned structure, the solar panels tilt at different angles due to gravity, making them prone to swaying and hindering efficient automated cleaning. Therefore, a flexible photovoltaic cleaning device for photovoltaic supports is proposed. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a flexible bracket photovoltaic cleaning device, which solves the problem that existing flexible bracket photovoltaic solar panels cannot be cleaned intelligently, efficiently, and continuously using ordinary walking cleaning equipment.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] A flexible bracket photovoltaic cleaning device includes a hanging frame with multiple hanging ropes connected to it, and a drone connected to each rope. An equipment frame is located below the hanging frame. Symmetrical lead screws are rotatably mounted on both sides of the equipment frame. A guide rod is mounted on one side of each lead screw, parallel to and on the equipment frame. A slider is threaded onto the outer side of each lead screw, and the slider is also slidably mounted on the outer side of the guide rod. A rotating plate is rotatably connected between the slider and the hanging frame. An extension seat is connected to the slider. The end of the rotating plate furthest from the hanging frame... The upper end of the hanging frame is also equipped with a sleeve frame, which supports and fits the bottom of the drone. The lead screws on the front and rear sides are connected to cross-shaped slot plates at one end. A rotating cylinder is also provided between the lead screws on the front and rear sides and is rotatably mounted on the equipment frame. The two ends of the rotating cylinder are slidably equipped with cross-shaped chucks that cooperate with the cross-shaped slot plates on both sides. The rotating cylinder is equipped with a clutch assembly, which is used to drive the lower cross-shaped chuck to engage with the lower cross-shaped slot plate when the equipment frame is attached to the inclined solar panel.

[0008] A telescopic component is centrally mounted on the equipment frame, and the front and rear output ends of the telescopic component are connected to a clamping frame located outside the equipment frame, which clamps the two side frames of the solar panel. Sliding seats are slidably fitted on the front and rear ends of the left and right inner walls of the equipment frame. Sliding rods are slidably fitted inside the sliding seats, and the lower ends of the two sliding rods on the same side are connected to a guide rail.

Gear three is mounted on the outside of the rotating shaft. The rotating shaft is located between the bidirectional lead screw and the rotating cylinder, which are parallel to each other on both sides. The two sides of gear three mesh with gear one and gear two, respectively. The slide is threaded onto the outside of the bidirectional lead screw.

[0013] Preferably, the threads of the bidirectional lead screw on the two sides of the gear two have opposite directions, and the slide blocks on the front and rear sides are symmetrically threaded on the outside of the bidirectional lead screw on the front and rear sides of the gear two. A spring two, which is sleeved on the outside of the slide block, is connected between the upper end of the slide rod and the upper end face of the slide block.

[0014] Preferably, the separation assembly includes a push rod, a threaded cylinder, a stud, a push rod, a collar, a lever, a frame, and a lever plate. The collar is rotatably fitted onto the outside of the cross chuck. The lever is connected to the lower end of the collar and extends through the equipment frame to its lower side. The push rod is slidably mounted on the equipment frame on the side where the front and rear levers are far apart. The ends of the push rods on the front and rear sides that are close to each other respectively engage with the ends of the front and rear levers that are far apart.

A slide groove is also provided on the equipment frame, and the lower end of the toggle block slides within the slide groove and extends through the slide groove to the lower side of the equipment frame.

[0016] Preferably, the front and rear top rods are rotatably connected to each other at their close ends, and the two front and rear top rods on the same left and right sides are rotatably connected to a horizontal plate at their ends away from their respective top rods. The lower end face of the horizontal plate is in contact with and slides against the upper end of the guide rail.

[0017] The beneficial effects of this invention are:

[0018] 1. The technical solution of this invention controls a drone to suspend the equipment frame via a rope, and places the frame plate 1 on the inclined upper and lower edges of the solar panel. At this time, both the equipment frame and the suspension frame are inclined and parallel to the solar panel. The square block slides downwards under the action of gravity until the cross chuck and the cross slot plate on the lower screw 1 abut or are secured. Then, the servo motor is controlled to run, driving the rotating drum to rotate. After the lower screw 1 is secured in the cross chuck and the cross slot plate, it rotates with the rotating drum to drive the slider to slide, causing the rotating plate 1 to rotate until the suspension frame is pushed to a horizontal state, which facilitates the horizontal landing of the drone on the suspension frame. The frame also limits the bottom of the drone to ensure that the drone can land during the subsequent cleaning process without raising a lot of dust due to controlled hovering, thus improving the cleaning effect, reducing drone energy consumption, increasing cleaning time, ensuring the drone is stable during cleaning and will not fall, and improving the universality of the device for adapting to solar panels of different sizes.

[0019] 2. The technical solution of this invention controls the two side frames to move closer together by the retraction of the telescopic component, so that the frame plates of the two side frames can firmly clamp the two side frames of the solar panel, ensuring the stability of the equipment frame on the solar panel and its parallel support. When the two side frames move closer together, the frame body moves closer together, the lever plate on the frame body will contact the push rod, causing the top rods on the front and rear sides to move closer together and contact their respective lever blocks. Then, the lever blocks push the cross chucks on both sides back to be centered in the rotating drum and between the first lead screw on the front and rear sides, ensuring that the lower cross chuck is no longer inserted into the cross slot of the lower lead screw under the action of gravity. At this time, the operation of the servo motor will no longer act on the first lead screw, ensuring the horizontal stability of the hanging frame, so that it can drive the bidirectional lead screw to move, so as to adjust the front and rear guide rails to move closer or further apart, and control the sliding of the cleaning seat through the guide rails to achieve comprehensive and efficient cleaning of the surface of the solar panel.

[0020] 3. The technical solution of the present invention, by bringing the top rods on the front and rear sides closer together, can also drive the rotating plate two to push the horizontal plate down, and push the guide rail down through the horizontal plate, and compress the spring two, so that before the clamping frame clamps the solar panel and stabilizes the equipment frame, the cleaning seat does not contact the surface of the solar panel. As it clamps, it can automatically drive the rubber scraper and cleaning cotton to effectively adhere to the surface of the solar panel, ensuring the stability of the clamping frame clamping the solar panel and improving the overall stability of the device operation.

[0033] The following will be combined with the appendix Figure 1 To be continued Figure 10The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, as Figures 1-10 As shown, this invention discloses a flexible bracket photovoltaic cleaning device, including a hanging frame 1, with multiple hanging ropes 2 connected to the hanging frame 1, and a drone 3 connected to each hanging rope 2. An equipment frame 5 is disposed below the hanging frame 1. Symmetrical lead screws 6 are rotatably mounted on both sides of the equipment frame 5. A guide rod 7, parallel to and on the equipment frame 5, is mounted on one side of each lead screw 6. A slider 8 is threaded onto the outer side of the lead screw 6, and the slider 8 is also slidably mounted on the outer side of the guide rod 7. A rotating plate 10 is rotatably connected between the slider 8 and the hanging frame 1. An extension seat 9 is connected to the slider 8. The rotating plate 10 is located away from the hanging frame 1. One end of the frame 1 is rotatably connected to the extension seat 9. The upper end of the hanging frame 1 is also equipped with a sleeve frame 4, which supports and fits the bottom of the drone 3. The lead screws 6 on the front and rear sides are close to each other and are connected to cross slot plates 11 at one end. A rotating cylinder 12 is also provided between the lead screws 6 on the front and rear sides and is rotatably installed on the equipment frame 5. The two ends of the rotating cylinder 12 are slidably provided with cross chucks 18 that cooperate with the cross slot plates 11 on both sides. A clutch assembly is provided on the rotating cylinder 12. The clutch assembly is used to drive the lower cross chuck 18 to engage with the lower cross slot plate 11 when the equipment frame 5 is attached to the inclined solar panel.

[0035] A telescopic component 35 is centrally mounted on the equipment frame 5. The front and rear output ends of the telescopic component 35 are connected to a clamping frame 37 located outside the equipment frame 5 and clamping the two side frames of the solar panel. Slide seats 39 are slidably mounted on the front and rear ends of the left and right inner walls of the equipment frame 5. Slide rods 40 are slidably mounted inside the slide seats 39. The lower ends of the two slide rods 40 on the same side are connected to a guide rail 42. A cleaning seat 43 for cleaning the solar panel is slidably mounted inside the guide rail 42. A drive assembly is provided on the equipment frame 5. The drive assembly is used to drive the rotating drum 12 to rotate and to drive the front and rear slide seats 39 to move closer or further apart. Separation assemblies are also provided on both sides of the lower end face of the equipment frame 5. When the two clamping frames 37 move closer together to clamp the two side frames of the solar panel, the separation assemblies drive the two cross chucks 18 to center and separate from the two cross chuck slots 11.

[0036] Among them, the guide rail 42 is an existing electric slide rail, etc., to automatically drive the cleaning seat 43 to slide, and the telescopic component 35 is an existing electric telescopic rod, electric hydraulic rod, etc.

[0037] This ensures that when the drone 3 lands on the hanging frame 1, the bottom of the drone 3 can fit into the frame 4, guaranteeing the stability of the drone 3 when it is parked.

[0038] A cleaning sponge 44 is installed in the middle of the lower end of the cleaning seat 43. Rubber scrapers 45 are also installed on both sides of the cleaning sponge 44 and are parallel to each other.

[0039] This allows the cleaning seat 43 to move in any direction controlled by the guide rail 42, so that the dust on the surface of the solar panel can be scraped off first by the rubber scraper 45, and then wiped by the cleaning cotton wiping 44 to improve the cleaning effect. If necessary, the equipment frame 5 can also carry relevant cleaning liquid to wet and rinse the cleaning cotton wiping 44. This is existing technology and will not be described in detail in the manual.

[0040] The frame 37 also includes frame plate 1 3701 and frame plate 2 3702. Frame plate 1 3701 is attached to the light-receiving surface of the solar panel, and frame plate 2 3702 is also connected to a rubber pad and is attached and clamped to the edge of the solar panel.

[0041] The spacing between the two side frames 37 is easily adjustable so that frame plate 3701 can be placed on the side edges of the solar panel, and then secured by frame plate 3702.

[0042] Example 2, as Figures 1-10 As shown, the present invention discloses a flexible bracket photovoltaic cleaning device. Compared with Embodiment 1, this embodiment discloses the structure of the clutch assembly.

[0043] The clutch assembly includes a square slide 14, a square block 15, and a square rod 17. The square slide 14 extends through both ends along the axis of the rotating cylinder 12. The square block 15 slides within the square slide 14. The square rod 17 is connected to both ends of the square block 15, and the two square rods 17 extend to both ends of the rotating cylinder 12 at their far ends and are connected to the cross chuck 18. Each side of the square block 15 is equipped with a roller 16 that is rolled and connected to the inner wall of the square slide 14.

[0044] When the solar panel is tilted, the equipment frame 5, which is supported on it, is also tilted. Under the action of gravity, the square block 15 will drive the two cross chucks 18 on both sides to slide downwards, and insert or abut against the cross chuck slot 11 on the lower lead screw 6. This will drive the slider 8 on the outside of the lower lead screw 6 to slide, and make the rotating plate 10 rotate. This will push the tilted hanging frame 1 to rotate to a horizontal position, which will facilitate the horizontal lowering of the drone 3 and its stable parking. This will prevent the drone 3 from raising dust during cleaning and improve the cleaning effect.

[0045] When the cross chuck 18 is not aligned with the cross chuck slot 11, as they rotate, once they are aligned, gravity will allow the chuck sleeve to be inserted.

[0046] Example 3, as Figures 1-10 As shown, the present invention discloses a flexible bracket photovoltaic cleaning device. Compared with Embodiment 2, this embodiment discloses the structure of the driving component.

[0047] The drive assembly includes gear 13, servo motor 19, bidirectional lead screw 20, gear 21, rotating shaft 22, and gear 3 23. Gear 13 is centrally mounted on the outside of the rotating drum 12. Servo motor 19 is mounted on the equipment frame 5 and is located on one side of the lead screw 6, which is coaxial on the front and rear sides. The servo motors 19 are arranged symmetrically on both sides of the equipment frame 5 in pairs. The two ends of the bidirectional lead screw 20 are respectively mounted on the output ends of the front and rear servo motors 19, which are close to each other. Gear 21 is centrally mounted on the outside of the bidirectional lead screw 20. The rotating shaft 22 is rotatably connected between the guide rod 7, which is coaxial on the front and rear sides. Gear 3 23 is mounted on the outside of the rotating shaft 22. The rotating shaft 22 is located between the bidirectional lead screw 20 and the rotating drum 12, which are parallel to each other on both sides. The two sides of gear 3 23 are respectively engaged with gear 13 and gear 21. The slide 39 is threaded on the outside of the bidirectional lead screw 20.

[0048] The threads of the double-acting lead screw 20 on both sides of the gear 21 have opposite directions. The slide blocks 39 on the front and rear sides are symmetrically threaded on the outside of the double-acting lead screw 20 on the front and rear sides of the gear 21. A spring 41 is sleeved on the outside of the slide block 40 between the upper end of the slide rod 40 and the upper end face of the slide block 39.

[0049] Example 4, as Figures 1-10 As shown, the present invention discloses a flexible bracket photovoltaic cleaning device. Compared with Embodiment 3, this embodiment discloses the structure of the separated components.

[0050] The separation assembly includes a push rod 28, a threaded cylinder 29, a stud 30, a push rod 31, a collar 32, a lever 33, a frame 36, and a lever plate 38. The collar 32 is rotatably sleeved on the outside of the cross chuck 18. The lever 33 is connected to the lower end of the collar 32 and extends through the equipment frame 5 to its lower side. The push rod 28 is slidably mounted on the equipment frame 5 on the side of the front and rear levers 33 that are far apart from each other. The ends of the push rods 28 on the front and rear sides that are close to each other respectively engage with the ends of the front and rear levers 33 that are far apart from each other. The threaded cylinder 29 is connected to the ends of the push rods 28 that are far apart from each other. The stud 30 is threadedly sleeved inside the threaded cylinder 29. The push rod 31 is connected to the ends of the studs 30 that are far apart from each other. The ends of the push rods 31 on the front and rear sides that are far apart from each other both penetrate the threaded cylinder 29 and extend to the outside of the threaded cylinder 29. The frame 36 is connected to the clamping frame 37. The lever plate 38 is connected to both sides of the frame 36 and engages with the extension ends of the push rods 31 on their respective sides.

[0051] When the two side frames 37 are brought closer together to clamp the solar panel, the push rod 31, stud 30, threaded cylinder 29 and top rod 28 can slide to drive the front and rear side paddle blocks 33 and cross chuck 18 back to the two side screws 6, and cancel the locking position of the lower cross chuck 18 and cross slot plate 11, so as to facilitate the independent control of the bidirectional screw 20 to rotate, and drive the front and rear side guide rails 42 to move closer or further apart, so as to achieve comprehensive and efficient cleaning of the solar panel.

[0052] Mounting seats 24 are connected to both sides of the lower end face of the equipment frame 5. Guide rods 25 are connected to the front and rear ends of the mounting seats 24. A sleeve 26 is connected to the top rod 28. The sleeve 26 is slidably fitted on the outside of the guide rods 25. A spring 27 fitted on the outside of the guide rods 25 is connected between the sleeve 26 and the mounting seat 24. A slide groove 34 is also provided on the equipment frame 5. The lower end of the toggle block 33 slides within the slide groove 34 and extends through the slide groove 34 to the lower side of the equipment frame 5.

[0053] The front and rear top rods 28 are rotatably connected to rotating plates 46 at their close ends. The two rotating plates 46 on the same left and right sides are rotatably connected to a horizontal plate 47 at their ends away from their respective top rods 28. The lower end of the horizontal plate 47 is in contact with and slides against the upper end of the guide rail 42.

[0054] Working principle:

[0055] According to the size of the solar panel to be cleaned, the telescopic component 35 is adjusted in advance to adjust the distance between the two side frames 37 until the frame plates 371 of both side frames 37 can fall on the inclined upper and lower edges of the solar panel, and the frame plate 3702 does not contact the inclined upper and lower edges of the solar panel. Then, the push rods 31 on both sides are rotated simultaneously to drive the studs 30 to move in their respective threaded cylinders 29 until the distance between the far ends of the push rods 31 on the front and rear sides can be close to the close surfaces of the upper plates 38 of the frame 37 after the distance between the two sides is adjusted. This ensures that when adjusting the distance between the two side frames 37, the distance between the close sides of the frame plates 3701 on both sides is adjusted to be less than the width of the solar panel, so as to facilitate the subsequent hoisting and splicing of the solar panel by the drone 3. At the same time, when it is clamped with the solar panel in the subsequent adjustment, it can also directly drive the plate 38 to contact the push rod 31, thereby pushing the top rod 28 to slide. This can improve versatility and adapt to the use of solar panels of different sizes.

[0056] Specifically, the drone 3 is controlled to suspend the equipment frame 5 via the suspension rope 2, and the frame plates 3701 on both sides of the equipment frame 5 are placed on the inclined upper and lower edges of the solar panel. At this time, both the equipment frame 5 and the suspension frame 1 are inclined and parallel to the solar panel. The square block 15 slides downwards under the action of gravity until the cross chuck 18 abuts or engages with the cross slot 11 on the lower lead screw 6. Then, the servo motor 19 is controlled to run, driving the bidirectional lead screw 20 to rotate. Since gear 3 23 meshes with gear 1 13 and gear 2 21, gear 2 21 will drive the rotating drum 12 to rotate along with the rotation of the bidirectional lead screw 20, so that the lower lead screw 6 engages with the cross slot 11. After the sleeve is inserted into the disc 18 and the cross-shaped slot disc 11, it rotates with the rotating cylinder 12 to drive the slider 8 to slide, so that the rotating plate 10 rotates until the hanging frame 1 is pushed to a horizontal state relative to the equipment frame 5. At this time, the equipment frame 5 is tilted and the hanging frame 1 is horizontal, which makes it easy to land the drone 3 horizontally on the hanging frame 1. The bottom of the drone 3 is limited by the sleeve frame 4 to ensure that the drone 3 can land during the subsequent cleaning process without raising a lot of dust due to controlled hovering, thus improving the cleaning effect, reducing the energy consumption of the drone 3, increasing the cleaning time, and ensuring that the drone 3 is stable during the cleaning process and will not fall. It also improves the universality of the device for adapting to solar panels of different sizes.

[0057] When the cross chuck 18 cannot be directly fitted into the cross chuck slot 11, the rotation of the double-acting screw 20 and the transmission between gear 13, gear 21 and gear 323 can cause the rotating drum 12 to drive the cross chuck 18 to rotate until it is fitted into the cross chuck slot 11 and then, under the action of gravity, it is fitted into place.

[0058] The telescopic component 35 retracts to control the two side frames 37 to move closer together, allowing the frame plates 3702 of the two side frames 37 to securely clamp the side frames of the solar panel, ensuring the stability of the equipment frame 5 on the solar panel and its parallel support. When the two side frames 37 move closer together, causing the frame body 36 to move closer together, the lever plate 38 on the frame body 36 will abut against the push rod 31, causing the front and rear push rods 28 to move closer together and abut against their respective lever blocks 33. This, in turn, pushes the two side cross chucks 18 back to their center position within the rotating drum 12 and between the front and rear lead screws 6, ensuring that the lower cross chuck 18 is no longer inserted into the cross slot 11 on the lower lead screw 6 under gravity, and thus... In the centered state, the operation of servo motor 19 will no longer affect lead screw 6, ensuring the horizontal stability of the hanging frame 1. This allows it to drive the bidirectional lead screw 20 to adjust the front and rear guide rails 42 to move closer or further apart. The guide rails 42 control the sliding of the cleaning seat 43, allowing the rubber scraper 45 to scrape the dust on the solar panel. The cleaning cotton wiping 44 can then wipe the surface of the solar panel after it has been scraped by the rubber scraper 45, achieving comprehensive and efficient cleaning of the solar panel surface. By operating a set of servo motors 19, it is possible to flexibly control the two guide rails 42 to move closer or further apart, and drive the hanging frame 1 to tilt relative to the equipment frame 5 and rotate to a horizontal state.

[0059] The top rods 28 on the front and rear sides move closer to each other, which can also drive the rotating plate 46 to push the horizontal plate 47 down, and push the guide rail 42 down through the horizontal plate 47, and compress the spring 41 so that before the clamping frame 37 clamps the solar panel and stabilizes the equipment frame 5 stage, the cleaning seat 43 does not contact the surface of the solar panel. As it clamps, it can automatically drive the rubber scraper 45 and the cleaning cotton swab 44 to effectively adhere to the surface of the solar panel, ensuring the stability of the clamping frame 37 clamping the solar panel, improving the overall stability of the device, and ensuring the cleaning effect.
