Description

Technical Field

[0001] This invention relates to the field of photovoltaic maintenance equipment technology, specifically a solar photovoltaic power generation cleaning mechanism. Background Technology

[0002] With the development of modern industry, the global energy crisis and air pollution problems are becoming increasingly prominent. Traditional fuel energy is decreasing day by day, and photovoltaic power generation, as one of the main green energy sources, is being used more and more, with the number and scale of photovoltaic power plants increasing. Once a photovoltaic power plant is built, the surface of the photovoltaic panels needs to be cleaned regularly to maintain power generation efficiency. This is especially important in areas with pollution and dust. Therefore, when conditions permit, it is necessary to clean the photovoltaic panels regularly.

[0003] Traditional photovoltaic (PV) panels are often fixed in place and cannot adjust their angle according to changes in the sun's position. This results in limited power generation efficiency during sunrise and sunset, as well as in seasons with significant variations in the sun's altitude. Traditional PV systems require regular manual cleaning to remove dust, debris, and other accumulated materials from the blades, which is not only labor-intensive but also increases maintenance costs. Fixed PV panels typically require a large space for installation, especially in space-constrained areas (such as urban rooftops). Under variable weather conditions, fixed PV panels cannot adapt to different sunlight conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a solar photovoltaic power generation cleaning mechanism, which solves the problems of traditional photovoltaic panels, which are limited in power generation efficiency and increase maintenance costs due to fixed installation, inability to adjust angle, need for regular manual cleaning, and low space utilization, especially in areas with variable sunlight conditions.

[0019] Working Principle: This device serves as the installation and main cleaning structure for photovoltaic panels. A multi-angle energy-concentrating mechanism mounted on the base supports and secures the panels. Simultaneously, a linkage deployment mechanism synchronously mounted on the multi-angle energy-concentrating mechanism drives its expansion and contraction at different times. During the expansion and contraction process, the multi-angle energy-concentrating mechanism can also be used to wipe and clean the photovoltaic panels. First, the photovoltaic panels are installed on the support plate included in the multi-angle energy-concentrating mechanism. Then, the multi-faceted focusing mechanism and the active extension mechanism are activated. The multi-faceted focusing mechanism is installed on the exposed top of the frame. When the hydraulic drive component of the active extension mechanism is activated, it outputs hydraulic force to pull the panel's extension and retraction. A U-shaped drive rod is fixed at one end. Through its U-shaped structure, the drive rod outputs tension to a linkage shaft located above the fixed platform. Simultaneously, the linkage shaft pulls an extension sleeve at one end. The extension sleeve then outputs the tension through a third linkage lever to a linkage pry bar. This pry bar generates a prying force, causing the rotating frame fixed to the pry bar to rotate the support plate along the end of the L-shaped extension platform. As the hydraulic drive reaches its output limit, the rotating frame rotates the support plate along the L-shaped extension platform to an inclined angle, allowing it to receive direct sunlight. Simultaneously, the linkage shaft is displaced, pushing the first linkage lever at its other end. This first linkage lever, supported by a support rod mounted on top of the fixed platform, also pushes... The second linkage rod rises and unfolds, simultaneously pushing the lifting lever and the rotating shaft of the central refractor connected to the other end of the lifting lever upwards along the straight slide groove added to the angle bracket. The second linkage rod also pushes the contact frame upwards, and the central refractor, under the push of the contact frame, tilts towards the support plate. As the second linkage rod rises, it also drives the central linkage rod to rise. The central linkage rod rises and passes through the central refractor, pushing the two side linkage rods installed at the top. Then, the side linkage rods push out the side refractors on both sides of the central refractor, which are installed by hinges, so that the side refractors face the support plate at their own tilt angle. The focusing photovoltaic structure is thus unfolded, and the photovoltaic panel can be placed on it. On the support plate, sunlight is concentrated and refracted to improve the drying efficiency of the artwork. The reverse output of the hydraulic drive mechanism causes the side refraction plates to fold in the opposite direction as the plate descends. The support plate, using a rotating frame, rotates and folds along the L-shaped extension platform towards the central refraction plate, rapidly retracting the sunlight-focusing photovoltaic structure. When unfolded, sunlight passes through two sets of side refraction plates and is focused onto the support plate fixed to the rotating frame. The support plate maximizes sunlight reception, thus improving the photovoltaic focusing efficiency. Simultaneously, based on the characteristic of sunrise in the east and sunset in the west, the drive transmission mechanism is activated. The output motor within the drive transmission mechanism generates rotational torque, which is output to the drive gear inside the fixed platform. The drive gear then transmits power to the meshing gear disc.The gear disk drives the fixed platform and the entire active extension mechanism to face the sunlight-exposed area at different times of the day. At night or during periods without sunlight, the supporting plate and the side-reflecting plates distributed on both sides can be folded up through the linkage unfolding mechanism and the multi-angle energy-concentrating mechanism. After the side-reflecting plates are folded up, they will move closer together, and the cleaning structure on the back side, including the side-mounted frame, will move closer together and face the photovoltaic power generation panel onto the supporting plate. The supporting plate, carrying the photovoltaic power generation panel, rotates and folds up with the rotating frame, attaching to the cleaning structure on the side-reflecting plate. The drive equipment, including the motor, opens the drive screw installed on the side-mounted frame. The device rotates within the side-mounted frame. A rectangular frame structure, also mounted on the back of the side-refracting plate, has wiping cotton on its horizontal side beams. The rectangular frame is mounted on a drive screw via a nut block at one end. As the drive screw rotates, it moves the rectangular frame back and forth on the back of the side-refracting plate. The wiping cotton on its side beams, upon contacting the photovoltaic panel fixed to the support plate, uses the rectangular structure to clean the light-receiving surface of the photovoltaic panel while reducing the installation area. Cleaning continues until the photovoltaic panel unfolds and generates electricity following the multi-angle energy-concentrating mechanism and the linkage deployment mechanism.

[0020] This invention provides a solar photovoltaic power generation cleaning mechanism. It has the following beneficial effects:

[0021] 1. The present invention has an integrated cleaning function: the device is designed with an integrated cleaning system that automatically wipes the photovoltaic panel when it is unfolded and retracted through a multi-angle energy-concentrating mechanism. This automatic cleaning function can effectively remove accumulated dust and impurities, maintain the high efficiency of the photovoltaic panel, and thus improve the long-term operating efficiency and power generation performance of the entire system.

[0022] 2. This invention possesses automated and flexible adjustment capabilities: by using a multi-angle energy-concentrating mechanism and an active extension mechanism, the photovoltaic panel can automatically adjust to the optimal angle at different times to receive the maximum amount of sunlight. This automated angle adjustment not only improves energy utilization but also reduces the need for manual adjustments, thereby increasing the overall system efficiency and convenience.

[0023] 3. This invention features intelligent directional drying: the equipment design includes the ability to automatically adjust the focusing photovoltaic angle according to changes in the sun's position. Through the automatic positioning of the active extension mechanism, the artwork is always positioned to face the optimal sunlight angle, thereby improving drying efficiency. The design of the central and side refractive plates not only protects the artwork from direct, strong light but also enhances the photothermal effect through focusing and reflection, accelerating the drying process.

[0024] 4. Modular and compact design of the invention: The structural design of the device takes space efficiency into account. Through the compact layout of the linkage mechanism and the side-mounted folding design, the system can occupy less space when not in use, while being quickly deployed when needed, which enhances the practicality and applicability of the system to application scenarios of different scales.

[0036] Please see the appendix Figure 1 -Appendix Figure 3 A solar photovoltaic power generation cleaning mechanism includes: a base platform 1, a fixed structure for the solar photovoltaic power generation cleaning mechanism, a multi-angle focusing mechanism 2 mounted on the base platform 1, an active extension mechanism 3 mounted on a portable transport mechanism 3 and connected to the multi-angle focusing mechanism 2, and a drive transmission mechanism 4 mounted on the multi-angle focusing mechanism 2.

After a period of use, while retracting, the multi-angle focusing mechanism 2 can also be used to wipe and clean the photovoltaic panels.

[0037] Please see the appendix Figure 1 -Appendix Figure 9The multi-faceted focusing mechanism 2 is located on the base platform 1 and is used to focus photovoltaic sunlight and refract it onto the photovoltaic panel. The multi-faceted focusing mechanism 2 includes a fixed platform box 21, which is fixedly connected to the top of the base platform 1. A working turntable 22 is rotatably connected to the top of the fixed platform box 21. An L-shaped extension platform 23 is fixedly connected to the side wall of the working turntable 22. A rotating frame 24 is rotatably connected to the end of the L-shaped extension platform 23 away from the working turntable 22.

A straight slide groove 27 is provided inside the folding bracket 26. A central refractor 28 is movably connected inside the folding bracket 26 through the straight slide groove 27. The bottom wall of the central refractor 28 is fixedly connected to... The multi-faceted focusing mechanism 2 includes a contact frame 29, side refractive plates 210 rotatably connected to both sides of the central refractive plate 28, and two sets of side frames 211 and a rectangular frame 213 arranged opposite to each other on the side refractive plates 210. A drive screw 212 is rotatably connected inside the side frame 211. The outer surfaces of the two horizontal side beams of the rectangular frame 213 are provided with wiping cotton structures. A nut block 214 is provided at one corner of the inner side wall of the rectangular frame 213. The rectangular frame 213 is displaced on the drive screw 212 through the thread of the nut block 214. The active extension mechanism 3 is located on the multi-faceted focusing mechanism 2 and works with the rotating frame 24, the central refractive plate 28 and the contact frame 29 to fold and unfold the photovoltaic cleaning structure. The active extension mechanism 3 includes a linkage shaft 31, a support rotating rod 39 and a hydraulic drive. Component 38, linkage shaft 31 is slidably connected to the top of the working turntable 22. One end of linkage shaft 31 is rotatably connected to linkage rod 1 32, and the other end of linkage rod 1 32 is rotatably connected to linkage rod 2 33. The other end of linkage rod 2 33 is rotatably connected to the bottom of the contact frame 29. One end of linkage shaft 31 near the rotating frame 24 is fixedly connected to an extension sleeve 34. The other end of extension sleeve 34 is rotatably connected to linkage rod 3 35, and the other end of linkage rod 3 35 is rotatably connected to a linkage pry bar 36. Linkage pry bar 36 is fixedly connected to the side wall of the rotating frame 24. A U-shaped drive rod 37 is fixedly connected inside extension sleeve 34. The curved part of the bottom surface of the U-shaped drive rod 37 extends to the bottom of the working turntable 22 and is fixedly connected to the telescopic end of the hydraulic drive component 38. Component 38 is fixedly connected to the bottom of the working turntable 22. The connecting part of the first linkage rod 32 and the second linkage rod 33 is rotatably connected to the supporting rod 39. The other end of the supporting rod 39 is rotatably connected to the top of the working turntable 22. The top of the second linkage rod 33 is rotatably connected to the central linkage rod 310. The central linkage rod 310 passes through the side wall of the central refraction plate 28 and extends to the top of the hydraulic drive component 38. The multi-angle energy-concentrating mechanism 2 can be used to wipe and clean the photovoltaic power generation panel. First, the photovoltaic panel for power generation is installed on the support plate 25 included in the multi-angle energy-concentrating mechanism 2. The multi-faceted focusing mechanism 2 and the active extension mechanism 3 are then activated. The multi-faceted focusing mechanism 2 is installed in the open position on the top of the frame. After the hydraulic drive component 38 included in the active extension mechanism 3 is activated,Its output hydraulic force pulls the U-shaped drive rod 37 fixed at its telescopic end. The U-shaped drive rod 37 outputs the pulling force to the linkage shaft 31 located above the fixed platform 21 through its U-shaped structure. At the same time, the linkage shaft 31 pulls the extension sleeve 34 installed at one end. The extension sleeve 34 outputs the pulling force to the linkage pry bar 36 through the linkage rotating rod 35. The linkage pry bar 36 generates a prying force, causing the rotating frame 24 fixed to the linkage pry bar 36 to drive the bearing plate 25 to rotate along the end of the L-shaped extension platform 23 until the hydraulic drive component 38 reaches its output limit. At the same time, the rotating frame 24 drives the bearing plate 25 to rotate along the L-shaped extension platform 23 to an inclined angle, and uses the inclined angle to receive direct sunlight from the outdoors. The linkage shaft 31 is pulled and displaced. Simultaneously, the linkage rod 32 installed at its other end is pushed. Supported by the support rod 39 installed on the top of the fixed platform 21, the linkage rod 32 pushes the linkage rod 33 upwards and unfolds. At the same time, the output of the linkage shaft 31 pushes the lifting lever 312 and the rotating shaft of the central refraction plate 28 connected to its other end to rise along the linear slide 27 installed on the angle bracket 26. The linkage rod 33 also pushes the contact frame 29 upwards. The central refraction plate 28, pushed by the contact frame 29, tilts towards the bearing plate 25. As the linkage rod 33 rises, it also drives the central linkage rod 310 upwards. The central linkage rod 310 rises and passes through the central refraction plate 28, simultaneously pushing the top... The two side linkage rods 311 are installed, which in turn push out and unfold the side refraction plates 210 on both sides of the central refraction plate 28, which are hinged together. This causes the side refraction plates 210 to tilt towards the support plate 25, thus unfolding the photovoltaic focusing structure. The photovoltaic panel can then be placed on the support plate 25 to improve the drying efficiency of the artwork by focusing and refracting sunlight. Alternatively, the reverse output of the hydraulic drive component 38 can cause the side refraction plates 210 to fold in the direction of descent, while the support plate 25 rotates and folds along the L-shaped extension platform 23 towards the central refraction plate 28 using the rotating frame 24. This rapid linkage unfolds the sunlight focusing photovoltaic structure. When unfolded, sunlight is focused onto the fixed point by the two sets of side refraction plates 210. The carrier plate 25 on the rotating frame 24 receives sunlight to the maximum extent, thereby improving the focusing photovoltaic efficiency. At night or during periods without sunlight, the carrier plate 25 and the side refraction plates 210 distributed on both sides can be folded up through the linkage unfolding mechanism 3 and the multi-angle energy concentrating mechanism 2. After the side refraction plates 210 are folded up, they will move closer together, and the cleaning structure on the back side, including the side frame 211, will move closer together and face the photovoltaic power generation panel onto the carrier plate 25. The carrier plate 25, carrying the photovoltaic power generation panel, rotates and folds up with the rotating frame 24, and will be attached to the cleaning structure on the side refraction plate 210. The drive device, including the motor, opens the drive screw 212 installed on the side frame 211, causing it to rotate within the side frame 211.The rectangular frame 213, also installed on the back side of the side refraction plate 210, is a frame structure. A wiping cotton structure is added to its horizontal side beams. The rectangular frame 213 is mounted on the drive screw 212 using a nut block 214 at one end corner. As the drive screw 212 rotates, it drives the rectangular frame 213 to move back and forth on the back side of the side refraction plate 210. The wiping cotton on its side beams, upon contacting the photovoltaic panel fixed on the support plate 25, uses the rectangular structure to wipe and clean the light-receiving surface of the photovoltaic panel while reducing the installation area. Cleaning continues until the photovoltaic panel unfolds and generates electricity following the multi-angle energy-concentrating mechanism 2 and the linkage deployment mechanism 3.

[0038] Please see the appendix Figure 1 -Appendix Figure 4 The drive transmission mechanism 4 is located on the portable transport mechanism 3 and works in conjunction with the fixed platform 21 and the working turntable 22 to drive the photovoltaic cleaning structure and the unfolding structure to rotate, so as to receive the maximum amount of focused photovoltaic sunlight at different times. The drive transmission mechanism 4 includes an output motor 41, which is fixedly connected to the top of the fixed platform 21. The motor shaft of the output motor 41 extends into the fixed platform 21 and is fixedly connected to a drive gear 42. The drive transmission mechanism 4 also includes a gear disk 43, which is rotatably connected to the inside of the fixed platform 21. The rotation shaft of the gear disk 43 is fixedly connected to the bottom of the working turntable 22. The gear disk 43 is meshed with the key end of the drive gear 42. The two ends of the central linkage rod 310 are rotatably connected to the side linkage rod 311. The other end of the side linkage rod 311 is rotatably connected to the top wall of the side refraction plate 210. According to the characteristic of sunrise in the east and sunset in the west, the drive transmission mechanism 4 can be activated. After the output motor 41 included in the drive transmission mechanism 4 generates rotational torque, it is output to the drive gear 42 inside the fixed platform 21. The drive gear 42 also transmits to the meshing gear disk 43, so that the gear disk 43 drives the fixed platform 21 and the entire active extension mechanism 3 to face the sunlight area at different times in real time.
