Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment maintenance technology, specifically relating to a fully automatic cleaning robot for photovoltaic modules. Background Technology

[0002] With the steady advancement of the national "dual-carbon" energy strategy, the installed capacity of photovoltaic power plants has been increasing year by year, and large-scale wind and solar power bases have become an important development model for new energy power generation in recent years. As the core component of a solar power generation system, the surface cleanliness of photovoltaic modules directly affects power generation efficiency. For example, dust adhering to the surface can lead to a decrease in the power generation efficiency of photovoltaic modules, and localized shading from stubborn pollutants such as bird droppings can even cause hot spot effects, severely shortening the lifespan of the modules. Because a large number of photovoltaic power plants are used in northern my country, and the vegetation in northern regions is sparse, especially in areas near the western plateau where there is more wind and sand and less rainfall, relying solely on rainwater to wash the photovoltaic modules is insufficient to remove dust and other pollutants from the surface of the photovoltaic panels in a timely manner.

[0003] Therefore, photovoltaic modules need to be cleaned regularly. The existing methods of cleaning photovoltaic modules are mostly manual cleaning, which relies on high-altitude operations, resulting in low efficiency and high cost. Moreover, there are more than one photovoltaic module in a photovoltaic power station, which also poses safety hazards, especially in complex terrain (such as rooftops and desert photovoltaic power stations). Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic photovoltaic module cleaning robot with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fully automated photovoltaic module cleaning robot includes:

[0007] A cleaning assembly includes a cleaning brush, a cleaning drive assembly, and a linear displacement assembly. The cleaning drive assembly is located at the output end of the linear displacement assembly, and the cleaning brush is connected to the output end of the cleaning drive assembly. The linear displacement assembly is used to drive the cleaning brush to move along the length direction of the photovoltaic panel through the cleaning drive assembly. The cleaning brush is located above the photovoltaic panel and along the tilt direction of the tilted photovoltaic panel. The diameter of the cleaning brush gradually decreases from top to bottom.

[0008] A cleaning component is disposed behind the cleaning brush and is used to clean the photovoltaic panels after they have been cleaned.

[0009] As a further optimization of this utility model, the cleaning drive assembly includes a main shaft and a cleaning motor. A cleaning brush is provided on the main shaft, and the two ends of the main shaft are respectively connected to the output end of the cleaning motor.

[0010] As a further optimization of this utility model, the linear displacement assembly includes a displacement motor, a lead screw, a slide block, and a slide rail. The cleaning motor is fixedly mounted on the slide block, the slide block is slidably connected to the slide rail, and the slide block is threadedly connected to the lead screw. The input end of the lead screw is drivenly connected to the displacement motor, wherein the slide rail is fixed in position relative to the photovoltaic panel.

[0011] As a further optimization of this utility model, a protective cover is fixedly provided on one side of the slide rail, and the protective cover is located outside the sweeping motor.

[0012] As a further optimization of this utility model, a shield is provided on the side of the cleaning brush away from the photovoltaic panel, and a support rod is fixedly connected to the slide, with the end of the support rod away from the slide fixedly connected to the shield.

[0013] As a further optimization of this utility model, a slider is slidably connected inside the lower protective cover along the tilt direction of the photovoltaic panel. The sliding direction of the slider and the protective cover is consistent with the sliding direction of the slide block along the slide rail. The slider is rotatably connected to a baffle. A first protrusion is fixedly provided at the lower part of the baffle away from the protective cover. A second protrusion is fixedly provided on the lower protective cover. The second protrusion is corresponding to the first protrusion. A sleeve is sleeved on the main shaft. The sleeve passes through the baffle. A telescopic bladder is fixedly connected to the side of the sleeve. The telescopic bladder is fixedly connected to the baffle.

[0014] As a further optimization of this utility model, the fully automatic photovoltaic module cleaning robot also includes a support component, which includes a frame, and the photovoltaic panel is fixedly mounted on the frame via a mounting bracket.

[0015] As a further optimization of this utility model, the support assembly further includes a support column, a cantilever, and a bracket. The upper end of the support column is fixedly connected to the cantilever, and multiple brackets are fixedly installed on the cantilever. The multiple brackets are evenly distributed along the axial direction of the cantilever, and a frame is fixedly connected to the end of the bracket away from the cantilever.

[0016] As a further optimization of this utility model, the end of the bracket away from the cantilever is threaded with a bolt, the bolt head is slidably connected in a groove opened in the frame, and the bolt shank is threaded with a nut at the end of the bracket away from the frame, wherein the extension direction of the groove is consistent with the tilt direction of the photovoltaic panel.

[0017] As a further optimization of this utility model, the cleaning assembly includes a nozzle, a cleaning brush, and a cover plate. The cover plate is fixedly mounted on a slide. The cleaning brush and the nozzle are respectively arranged on the side of the cover plate facing the photovoltaic panel. Along the moving direction of the cleaning brush, the cleaning brush is located on the side of the nozzle away from the cleaning brush. The cleaning brush is rotatably mounted on the cover plate, and the input end of the cleaning brush is drivenly connected to a cleaning motor. The input end of the nozzle is connected to a water pipe, and the water pipe is connected to a water tank through a water pump.

[0018] The present invention has at least the following beneficial effects: The fully automatic photovoltaic module cleaning robot provided by the present invention includes a sweeping component and a cleaning component. The sweeping component includes a sweeping brush, a sweeping drive component and a linear displacement component. The sweeping brush is set above the photovoltaic panel and along the tilt direction of the tilted photovoltaic panel. The diameter of the sweeping brush gradually decreases from top to bottom. The sweeping drive component drives the sweeping brush to rotate, so that the sweeping brush with a special structure has a stronger sweeping force for dust, bird droppings and other pollutants deposited on the upper part of the photovoltaic panel. It can push the pollutants swept from the upper part to the lower part, and with the help of the pollutants' own gravity, it can quickly push the pollutants from the high point of the tilted photovoltaic panel to the low point. Moreover, when the lower end of the sweeping brush rolls, the length of the brush bristles is small and the linear speed of the brush bristles is also small, so as to reduce the back-carrying effect of the pollutants pushed to the lower end of the photovoltaic panel when the brush bristles rotate.

[0019] Moreover, along the tilt direction of the photovoltaic panel, a slider is slidably connected inside the lower protective cover. The slider is rotatably connected to a baffle. The baffle effectively prevents the pollutants swept down from splashing onto the cleaning motor below. With the interaction of the first and second protrusions, the baffle vibrates continuously, so as to make the pollutants on the baffle fall off quickly and prevent the pollutants from accumulating.

[0020] In addition, the frame used for installing photovoltaic panels is fixed to the bracket with bolts. The tilt angle of the photovoltaic panels can be determined by adjusting the tilt angle of the bracket. This adjustment function can adapt to the needs of fine adjustment of the spacing and angle of photovoltaic panels in different installation scenarios, such as optimizing the arrangement of photovoltaic panels according to the local sunlight angle.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, a fully automated photovoltaic module cleaning robot includes:

[0035] The cleaning assembly 1 includes a cleaning brush 11, a cleaning drive assembly, and a linear displacement assembly. The cleaning drive assembly is located at the output end of the linear displacement assembly, and the cleaning brush 11 is connected to the output end of the cleaning drive assembly. The linear displacement assembly is used to drive the cleaning brush 11 to move along the length direction of the photovoltaic panel 2 through the cleaning drive assembly. The cleaning brush 11 is located above the photovoltaic panel 2 and along the tilt direction of the tilted photovoltaic panel 2. The diameter of the cleaning brush 11 gradually decreases from top to bottom.

[0036] The cleaning component 4 is located behind the cleaning brush 11 and is used to clean the photovoltaic panel 2 after it has been cleaned.

[0037] It should be noted that, as Figure 2 As shown, the dashed line indicates the position of the rotation axis of the cleaning brush 11. Driven by the cleaning drive component, the cleaning brush 11 rotates at a constant speed. Driven by the linear displacement component, the cleaning brush 11 rotates while moving linearly along the length of the photovoltaic panel 2. Due to the structural feature of the cleaning brush 11 having a larger diameter at the top and a smaller diameter at the bottom, the linear velocity (v=ωr) of the brush bristles gradually decreases from top to bottom when the cleaning brush 11 rolls. This results in a stronger cleaning force from the cleaning brush 11 to the dust, bird droppings, and other pollutants deposited on the top of the photovoltaic panel 2. The larger diameter at the top and a smaller diameter at the bottom of the cleaning brush 11 also pushes the pollutants swept from the top towards the bottom. With the help of the pollutants' own gravity, the pollutants can be quickly pushed from the high point of the inclined photovoltaic panel 2 to the low point. Moreover, when the bottom of the cleaning brush 11 rolls, the length of the brush bristles is smaller and the linear velocity of the brush bristles is also smaller, so as to reduce the backflow of pollutants pushed to the bottom of the photovoltaic panel 2 when the brush bristles rotate.

[0038] After cleaning, the photovoltaic panel 2 is further cleaned by the cleaning component 4 to improve the cleaning effect.

[0039] For example, see [link to relevant documentation]. Figure 2 , Figure 3 and Figure 4 The cleaning drive assembly includes a main shaft 18 and a cleaning motor 17. A cleaning brush 11 is provided on the main shaft 18, and the two ends of the main shaft 18 are respectively connected to the output end of the cleaning motor 17.

[0040] Continue reading Figure 1 , Figure 3 and Figure 4 The linear displacement assembly includes a displacement motor, a lead screw 16, a slide block 15, and a slide rail 14. The cleaning motor 17 is fixedly mounted on the slide block 15, the slide block 15 is slidably connected to the slide rail 14, and the slide block 15 is threadedly connected to the lead screw 16. The input end of the lead screw 16 is drivenly connected to the displacement motor. The slide rail 14 is fixed in position relative to the photovoltaic panel 2.

[0041] In the above embodiment, the main shaft 18 is rotated synchronously by two cleaning motors 17, so that the cleaning brush 11 can rotate continuously. The lead screw 16 is driven to rotate by the shift motor, and under the constraint of the slide rail 14, the slide block 15 drives the cleaning motor 17 to move. Thus, the cleaning brush 11 rotates while moving in the length direction of the photovoltaic panel 2, so as to achieve comprehensive cleaning of the photovoltaic panel 2.

[0042] For example, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 6 The cleaning assembly 4 includes a nozzle 41, a cleaning brush 43, and a cover plate 42. The cover plate 42 is fixedly mounted on the slide 15. The cleaning brush 43 and the nozzle 41 are respectively arranged on the side of the cover plate 42 facing the photovoltaic panel 2. Along the moving direction of the cleaning brush 11, the cleaning brush 43 is located on the side of the nozzle 41 away from the cleaning brush 11. The cleaning brush 43 is rotatably mounted on the cover plate 42, and a cleaning motor is driven to the input end of the cleaning brush 43. A water pipe 44 is connected to the input end of the nozzle 41, and the water pipe 44 is connected to a water tank 46 through a water pump 45. Driven by the slide 15, the cover plate 42 moves the cleaning brush 43 and the nozzle 41 forward with the cleaning brush 11, thereby enabling the nozzle 41 to spray water onto the surface of the cleaned photovoltaic panel 2, and then the cleaning brush 43 wipes and cleans the sprayed surface of the photovoltaic panel 2, fully ensuring the cleaning effect of the photovoltaic panel 2.

[0043] For example, see [link to relevant documentation]. Figure 3 and Figure 4 A protective cover 19 is fixedly installed on one side of the slide rail 14, and the protective cover 19 is located outside the sweeping motor 17. This is to provide dustproof, bird droppings-proof, and sunproof protection for the sweeping motor 17.

[0044] For example, see [link to relevant documentation]. Figure 2 , Figure 3 and Figure 4A shield 12 is provided on the side of the cleaning brush 11 away from the photovoltaic panel 2. A support rod 13 is fixedly connected to the slide 15, and the end of the support rod 13 away from the slide 15 is fixedly connected to the shield 12. When the slide 15 moves, the support rod 13 drives the shield 12 to move synchronously with the cleaning brush 11 in a straight line, so that the shield 12 blocks the dust and pollutants swept up by the cleaning brush 11 and prevents the pollutants from being carried back to the rear position in the straight line movement direction of the cleaning brush 11.

[0045] Example 2

[0046] Based on Example 1, continue to refer to Figure 4 and Figure 5 Along the inclined direction of the photovoltaic panel 2, a slider 120 is slidably connected inside the lower protective cover 19. The sliding direction of the slider 120 and the protective cover 19 is consistent with the sliding direction of the slide block 15 along the slide rail 14. The sliding direction is the length direction of the rectangular photovoltaic panel 2. The slider 120 is rotatably connected to a baffle 121. A first protrusion 124 is fixedly provided at the lower part of the end of the baffle 121 away from the protective cover 19. A second protrusion 125 is fixedly provided on the lower protective cover 19. The second protrusion 125 is correspondingly provided to the first protrusion 124. A sleeve 122 is sleeved on the main shaft 18. The sleeve 122 passes through the baffle 121, and a telescopic bladder 123 is fixedly connected to the side of the sleeve 122. The telescopic bladder 123 is fixedly connected to the baffle 121.

[0047] When the slide block 15 slides along the slide rail 14, the main shaft 18 drives the baffle 121 to move through the sleeve 122, causing the baffle 121 to drive the slider 120 to slide. The pollutants swept by the cleaning brush 11 fall from below the photovoltaic panel 2. At this time, the baffle 121 is used to block the pollutants and prevent them from falling into the working area of ​​the cleaning motor 17 below. For the pollutants blocked by the baffle 121, the baffle 121 vibrates due to the intermittent contact between multiple first protrusions 124 and multiple second protrusions 125, so as to shake off the pollutants attached to the baffle 121. Considering the position of the main shaft 18, the telescopic bladder 123 is set so that when the baffle 121 vibrates, the telescopic bladder 123 between the main shaft 18 and the baffle 121 can fully block the pollutants, ensuring the blocking effect of the baffle 121.

[0048] It should be noted that the baffle 121 uses its own weight to maintain the frictional contact between the first protrusion 124 and the second protrusion 125.

[0049] Example 3

[0050] Based on Example 2, please continue reading Figure 2 and Figure 7The fully automated photovoltaic module cleaning robot also includes a support component 3, which comprises a frame 34. The photovoltaic panel 2 is fixedly mounted on the frame 34 via a mounting bracket 35. The frame 34 has a small contact area with the photovoltaic panel 2, which, for photovoltaic panels 2 in open outdoor areas, facilitates airflow to cool the panel 2, lowering its operating temperature and significantly improving power generation efficiency. Especially in high-temperature regions or during summer, this cooling effect effectively reduces efficiency degradation and increases power generation.

[0051] Continue reading Figure 7 The support assembly 3 further includes a support column 31, a cantilever 32, and a bracket 33. The upper end of the support column 31 is fixedly connected to the cantilever 32. Multiple brackets 33 are fixedly installed on the cantilever 32. The multiple brackets 33 are evenly distributed along the axial direction of the cantilever 32. The end of the bracket 33 away from the cantilever 32 is fixedly connected to a frame 34.

[0052] Continue reading Figure 8 The bracket 33, at the end furthest from the cantilever 32, is threaded with a bolt 36. The bolt head of the bolt 36 is slidably connected in a groove 37 formed in the frame 34. The shank of the bolt 36, at the end of the bracket 33 furthest from the frame 34, is threaded with a nut 38. The extension direction of the groove 37 is consistent with the tilt direction of the photovoltaic panel 2. This facilitates adjustment of the position of the frame 34 (including the photovoltaic panel 2 fixed on the frame 34) relative to the bracket 33 along the tilt direction. This adjustment function can adapt to the need for fine-tuning the spacing and angle of the photovoltaic panels 2 in different installation scenarios, such as optimizing the arrangement of the photovoltaic panels 2 according to the local sunlight angle. After determining the position of the frame 34, tighten the nut 38 to make the bolt head of the bolt 36 abut against the groove 37, thus ensuring a secure installation between the bracket 33 and the frame 34.

[0053] It should be noted that, in use, this fully automatic photovoltaic module cleaning robot starts the cleaning motor 17 and the shifting motor. The cleaning motor 17 drives the main shaft 18 to rotate, causing the cleaning brush 11 to rotate counterclockwise (towards...). Figure 6 Taking the orientation shown as an example, the surface of the photovoltaic panel 2 is cleaned of contaminants. Due to the structural feature of the cleaning brush 11 having a larger diameter at the top and a smaller diameter at the bottom, the linear velocity (v=ωr) of the brush bristles gradually decreases from top to bottom when the cleaning brush 11 rolls. This results in a stronger cleaning force from the cleaning brush 11 to the dust, bird droppings, and other contaminants deposited on the top of the photovoltaic panel 2. Furthermore, the larger diameter at the top and smaller diameter at the bottom of the cleaning brush 11 can push the contaminants cleaned at the top towards the bottom. With the help of the contaminants' own gravity, the contaminants can be quickly pushed from the high point of the inclined photovoltaic panel 2 to the low point. At the same time, the shift motor drives the lead screw 16 to rotate, causing the slide 15 to move linearly along the slide rail 14, so as to achieve uniform movement of the cleaning brush 11 along the length direction of the photovoltaic panel 2, thereby achieving a comprehensive cleaning of the photovoltaic panel 2.

[0054] During the cleaning process, the sliding seat 15 moves the cover plate 42 forward synchronously, and the water pump 45 delivers water from the water tank 46 to the spray nozzle 41 through the water pipe 44 to spray the cleaned photovoltaic panel 2 surface. Then, the cleaning motor drives the cleaning brush 43 to rotate counterclockwise (to... Figure 6 (Taking the orientation shown as an example), the cleaning brush 43 can thoroughly wipe the photovoltaic panel 2;

[0055] The pollutants pushed by the sweeping brush 11 fall off the lower end of the photovoltaic panel 2. The splashed pollutants are blocked by the baffle 121 to prevent them from falling into the operating area of ​​the sweeping motor 17 below. Under the interaction of the first protrusion 124 and the second protrusion 125, the baffle 121 vibrates to prevent pollutants from accumulating on the baffle 121. The fallen pollutants fall to the ground through the gaps in the frame 34.

[0056] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
