TECHNICAL FIELD
[0001] The present application relates to the field of photovoltaic equipment, in particular to a photovoltaic equipment positioning and maintenance device. BACKGROUND
[0002] Photovoltaic panels convert solar light into electrical energy by absorbing sunlight. Covering will directly block the light from shining on the cell, resulting in a decrease in the generation of photo-generated carriers, and a significant drop in output power. If it is a partial cover (such as covering 10% of the area): due to the "minimum current in series circuit" characteristic, the power generation current of the entire component or even the same group of strings will decrease with the increase of the covered area, and the actual power generation loss is often much higher than the covered area ratio (such as 10% cover may cause more than 30% power generation loss). If it is a complete cover: the power generation of the component is close to zero, which is equivalent to the complete failure of this part of the equipment. When the photovoltaic panel is partially covered (such as leaves, bird droppings), the cell in the covered area has much lower power generation efficiency than the normal cell around it, and it will change from a "power generation unit" to a "load", absorbing the electrical energy of the surrounding cells and generating local high temperature (up to more than 200℃), which may burn the cell and melt the solder strip in the short term, causing black spots and cracks on the panel. In the long term, it can accelerate the aging of the component and even cause the component to catch fire, which seriously threatens the safety of the photovoltaic system. In order to protect the power generation efficiency of the photovoltaic panel and the safety of the equipment, one of the core tasks of the daily maintenance of the photovoltaic panel is cleaning work to regularly remove dust, sand, leaves, bird droppings, etc. on the surface of the panel. However, the cleaning work in the maintenance of the photovoltaic panel is currently mostly done manually, which is time-consuming and labor-intensive. SUMMARY

[0013] In a preferred embodiment of the photovoltaic equipment positioning and maintenance device of the present invention: the distance from the bottom of the long plate to the outer wall of the rotating cylinder is less than the thickness of the sponge cylinder.
[0014] The beneficial effects of this invention are as follows: through the combined cleaning of the wiping and scraping components, the surface dirt and dirty water of the photovoltaic panel are thoroughly cleaned. At the same time, during the cleaning process, the timely collection by the collection cylinder and inner cylinder prevents secondary pollution of the photovoltaic panel by the dirt.

[0018] Reference Figure 1 This embodiment provides a photovoltaic equipment positioning and maintenance device, including, The cleaning unit 1 includes a wiping component 11 and a scraping component 12, and a movable part 2 is connected to the bottom of the cleaning unit 1. The cleaning part 1 can be fitted onto the outside of the photovoltaic component in cooperation with the moving part 2, and the moving part 2 can drive the cleaning part 1 to move on the surface of the photovoltaic component; The cleaning unit 1 is placed on the front of the photovoltaic panel, while the moving unit 2 is located on the back of the photovoltaic panel. The moving unit 2 can drive the rotating equipment to move continuously in the same direction along the surface of the photovoltaic panel. During the movement, the wiping part 11 and the scraping part 12 work together to clean the surface of the photovoltaic panel. Through the effect of cleaning while moving, the dirt on the surface of the photovoltaic panel is thoroughly cleaned, avoiding the hot spot effect caused by the dirt covering it, and preventing the photovoltaic panel from being damaged by the hot spot effect.
[0019] As an optional embodiment, the moving part 2 includes a telescopic member 21 and a rotating member 22 fixedly mounted on the telescopic member 21. The telescopic member 21 is connected to the cleaning part 1, and the rotating member 22 is arranged parallel to the cleaning part 1 with a certain distance between them. The distance between the rotating member 22 and the cleaning part 1 is increased by the telescopic member 21. At this time, the end of the photovoltaic panel is placed between the rotating member 22 and the cleaning part 1. After the cleaning part 1 aligns with the front of the photovoltaic panel, the telescopic member 21 begins to reduce the distance between the rotating member 22 and the cleaning part 1 until the rotating member 22 is attached to the back of the photovoltaic panel and the cleaning part 1 is attached to the front of the photovoltaic panel. At this time, the rotating member 22 rotates to move the cleaning part 1 along the surface of the photovoltaic panel, and the cleaning part 1 cleans the photovoltaic panel during the movement.
[0020] As an optional embodiment, the wiping component 11 includes a rotating cylinder 111, with a sponge cylinder 112 sleeved on the outside of the rotating cylinder 111; the sponge cylinder 112 is attached to the surface of the photovoltaic panel; the sponge cylinder 112 is fixedly disposed on the outside of the rotating cylinder 111, and when the rotating cylinder 111 and the rotating component 22 are fitted onto the photovoltaic panel, the surface of the sponge cylinder 112 is in contact with the surface of the photovoltaic panel, so that when the rotating component 22 rotates and drives the sponge cylinder 112 to move, the sponge cylinder 112 can clean the surface of the photovoltaic panel; Furthermore, one end of the rotating cylinder 111 is connected to a gear, enabling the rotating cylinder 111 to be connected to an external drive device, such as the gear meshing with another set of gears, and the other gear being installed at the output end of the motor, so that the rotating cylinder 111 can rotate to clean the surface of the photovoltaic panel during its movement.
[0021] As an optional embodiment, the rotating cylinder 111 has a cavity inside, and a collecting cylinder 113 is rotatably connected in the cavity. The collecting cylinder 113 has a collecting port 114. The rotating cylinder 111 has multiple sets of elongated grooves 115 along the radial direction, and the collecting port 114 can correspond to the position of the elongated grooves 115. The collecting cylinder 113 is rotatably connected in the rotating cylinder 111. The collecting cylinder 113 has a cavity structure inside, and both ends of the collecting cylinder 113 and the rotating cylinder 111 are through-connected, so that the dirt entering the collecting cylinder 113 can be poured out. The collecting cylinder 113 has a collecting port 114 at the top, and the elongated grooves 115 on the rotating cylinder 111 are through-connected. Through the opening of multiple sets of elongated grooves 115, the dirty water absorbed by the sponge cylinder 112 can enter the collecting cylinder 113 through the collecting port 114 due to gravity when the elongated grooves 115 pass through the collecting port 114.
[0022] As an optional embodiment, the scraper 12 includes an outer cylinder 121, and multiple sets of arc-shaped scrapers 122 are fixedly provided on the surface of the outer cylinder 121 in the radial direction; a collection cavity M is formed between the inner wall of the arc-shaped scraper 122 and the outer wall of the outer cylinder 121, and the end of the arc-shaped scraper 122 is attached to the surface of the photovoltaic panel. Multiple sets of arc-shaped scrapers 122 are radially and equidistantly distributed on the outer cylinder 121. The number of sets of arc-shaped scrapers 122 is set according to the cleaning requirements. Baffles are connected between the two ends of the arc-shaped scrapers 122 and the outer cylinder 121, so that a collection cavity M with only one side penetrating is formed between the arc-shaped scrapers 122 and the outer cylinder 121. A follower structure is provided between the rotating cylinders 111 at the end of the outer cylinder 121, such as the pulley structure in the attached figure. Since the rotating cylinder 111 is connected to the drive structure, when the rotating component 22 drives the equipment to move, the outer cylinder 121 can rotate multiple sets of arc-shaped scrapers 122 to rotate, thereby making the arc-shaped scrapers 122 rotate to clean the surface of the photovoltaic panel. Furthermore, the openings of multiple collection chambers M all face the same side. When the rotating component 22 drives the equipment to move on the photovoltaic component, the outer cylinder 121 faces... Figure 4 Rotating in the direction indicated by the middle arrow allows the arc-shaped scraper 122 to rotate and scrape away dirt from the photovoltaic panel surface, then smoothly enter the collection chamber M to collect the scraped dirt. When using this device, it is preferable to start at the lower end of the photovoltaic panel so that after scraping away the dirt, the arc-shaped scraper 122 can better enter the collection chamber M along the angle of inclination of the photovoltaic panel surface. In this embodiment, the end of the arc-shaped scraper 122 is preferably made of rubber or similar material to avoid damaging the photovoltaic panel surface when scraping away dirt.
[0023] As an optional embodiment, both ends of the rotating cylinder 111 and the outer cylinder 121 are rotatably connected to the connecting frame 3. The telescopic component 21 is installed at the bottom of the connecting frame 3. By rotating the rotating cylinder 111 and the outer cylinder 121 to the connecting frame 3, the rotating cylinder 111 and the outer cylinder 121 can rotate during the cleaning process for cleaning. The bottom of both sets of connecting frames 3 are fixedly installed with telescopic components 21. In this embodiment, the telescopic component 21 is preferably a small cylinder, the bottom end of which is installed at the bottom of the connecting frame 3. The output end of the telescopic component 21 is fixedly connected to a hinge seat, and a rotating component 22 is rotatably connected to the hinge seat. The rotating component 22 is a roller structure. Both sets of rotating components 22 are connected to an external drive mechanism. The external drive mechanism drives the rotating component 22 to rotate, thereby enabling the rotating component 22 to drive the cleaning part 1 to move on the photovoltaic panel.
[0024] As an optional embodiment, a fixing frame 31 is also fixedly provided on the top of the connecting frame 3, and a set of long plates 32 is fixedly provided between the two sets of fixing frames 31. One side of the long plate 32 is provided with an inclined surface 33; the distance from the bottom of the long plate 32 to the outer wall of the rotating cylinder 111 is less than the thickness of the sponge cylinder 112. Both sets of connecting frames 3 are fixedly equipped with a fixing frame 31 at the top. The long plate 32 and the rotating cylinder 111 are provided with an inclined surface 33 on the opposite side of their rotation direction. Since the distance between the bottom of the long plate 32 and the outer wall of the rotating cylinder 111 is less than the thickness of the sponge, and the position of the long plate 32 corresponds to the position of the collection port 114, the sponge cylinder 112 is guided by the inclined surface 33 to smoothly enter between the long plate 32 and the rotating cylinder 111. Since the rotating cylinder 111 has multiple sets of long grooves 115, and the position of the collection port 114 can correspond to the long grooves 115, when the sponge cylinder 112 enters below the long plate 32, the sponge cylinder 112 is squeezed, causing the adsorbed dirty water inside to be squeezed out. The squeezed dirty water passes through the long grooves 115 and the collection port 114 and enters the collection cylinder 113. Thus, during the cleaning process, the sponge cylinder 112 can be cleaned in time to ensure the adsorption effect of the sponge cylinder 112, and the dirty water is collected by the collection cylinder 113 to avoid secondary pollution of the photovoltaic panel surface by the dirty water, thereby improving the cleaning effect.
[0025] As an optional embodiment, the outer cylinder 121 has an inner cylinder 123 inside, and the inner cylinder 123 has a through groove 124. The outer cylinder 121 has a slag discharge port 125 located in the collection chamber M. The inner cylinder 123 is rotatably connected to the outer cylinder 121, and the inner cylinder 123 has a through groove 124. The slag discharge port 125 is located on the outer cylinder 121 and is located at the inner edge of the arc-shaped baffle. In this embodiment, the outer wall of the inner cylinder 123 is in contact with the outer cylinder. The inner wall of 121 is designed to prevent dirt from entering between the outer cylinder 121 and the inner cylinder 123 during the rotation of the outer cylinder 121. The through groove 124 is opened near the top of the inner cylinder 123, so that the arc-shaped scraper 122 can pour the dirt in the collection chamber M into the inner cylinder 123 through the through groove 124 and the slag discharge port 125 during the rotation, thereby collecting the dirt cleaned by the arc-shaped scraper 122 and avoiding secondary pollution of the photovoltaic panel.
[0026] As an optional embodiment, a counterweight 116 is fixedly provided in both the inner cylinder 123 and the collecting cylinder 113. The counterweight 116 is fixedly provided at the bottom of the inner side of the inner cylinder 123 and the collecting cylinder 113. By setting the counterweight 116, it is ensured that when the rotating cylinder 111 and the outer cylinder 121 rotate, the inner cylinder 123 and the collecting cylinder 113 always remain in a fixed position, thereby ensuring the correspondence between the collecting port 114 and the long groove 115, and the correspondence between the slag discharge port 125 and the through groove 124.
[0027] In this embodiment, both the inner cylinder 123 and the collection cylinder 113 have hollow structures inside, and both ends of the two are through structures. Both ends of the inner cylinder 123 and the collection cylinder 113 are provided with conical surfaces, so that after cleaning, the collected dirty water and dirt can be poured out through the ends of the inner cylinder 123 and the collection cylinder 113 for the next use of the equipment.
[0028] In this embodiment, sensors can be installed at any location on the device to detect the photovoltaic panels during the cleaning process and to understand their status in a timely manner.
[0029] Working principle: Before cleaning the photovoltaic panel, spray water or diluted neutral detergent on the surface of the photovoltaic panel to soften stubborn stains such as bird droppings and oil stains. After the surface stains are softened, the telescopic component 21 pushes the rotating component 22 away from the cleaning part 1. At this time, the photovoltaic panel is placed between the rotating component 22 and the cleaning part 1 through the lower end of the photovoltaic panel. After placement, the telescopic component 21 moves the rotating component 22 so that the rotating component 22 fits against the back of the photovoltaic panel. At this time, the cleaning part 1 is in contact with the surface of the photovoltaic panel. After placement, the drive mechanism of the rotating component 22 and the cleaning section 1 is activated. The rotating component 22 rotates, driving the cleaning section 1 to move towards the other end of the photovoltaic panel. The rotating cylinder 111 and the outer cylinder 121 rotate synchronously. When the outer cylinder 121 rotates, it drives the arc-shaped scraper 122 to scrape off the softened dirt. The scraped dirt remains in the collection chamber M. When the outer cylinder 121 rotates until the slag discharge port 125 corresponds to the through groove 124 of the outer cylinder 123, the dirt in the collection chamber M enters the inner cylinder 123 along the arc of the arc-shaped scraper 122, thereby collecting the scraped dirt. At this time, the area located behind the outer cylinder 121... The rotating cylinder 111 drives the sponge cylinder 112 to perform a secondary cleaning of the photovoltaic panel. After passing over the surface of the photovoltaic panel, the sponge cylinder 112 absorbs the dirty water on its surface and promptly scrapes off the residual sewage after cleaning, preventing the sewage from drying and forming water stains, thus reducing the need for secondary cleaning. During the rotation of the rotating cylinder 111, the part of it located below the long plate 32 is squeezed, which causes the dirty water to enter the collection cylinder 113 through the long groove 115 and the collection port 114 for collection, preventing the photovoltaic panel from being contaminated again. After cleaning, the rotating part 22 can be pushed away from the photovoltaic panel by the telescopic part 21 to remove it. The cleaning process, achieved through the combined action of the wiping component 11 and the scraping component 12, thoroughly cleans the surface of the photovoltaic panel of dirt and water. Simultaneously, the timely collection by the collection cylinder 113 and the inner cylinder 123 prevents secondary contamination of the photovoltaic panel by the dirt. Furthermore, timely cleaning and maintenance of the photovoltaic panel surface prevents dirt (dust, bird droppings, fallen leaves, etc.) from forming a shading layer, thus improving the light absorption of the photovoltaic panel. Regular cleaning also prevents dirt from blocking light, reducing the risk of hot spots at the source, preventing cell burnout and module fires, and lowering maintenance and replacement costs.
[0030] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
