Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel maintenance, and more particularly to an intelligent cleaning robot for photovoltaic panels. Background Technology

[0002] With the growing global demand for renewable energy, photovoltaic power generation systems have been widely deployed in many regions to convert solar energy into electricity. However, the surface of photovoltaic panels is prone to accumulating dust, dirt, and debris, which reduces the photoelectric conversion efficiency of the photovoltaic panels and requires regular cleaning. Compared with manual cleaning, cleaning robots have high cleaning efficiency and low cleaning costs. The design and operation of robots follow safety standards, avoiding the potential dangers of manual cleaning.

[0003] Cleaning robots need to effectively remove dust, dirt, and debris from the surface of photovoltaic panels. Since the dirt varies in size and the adhesion strength of the dirt on the photovoltaic panel surface, ordinary cleaning robots will leave stains after cleaning the dirt with strong adhesion, resulting in poor overall cleaning effect. If the cleaning speed of the cleaning robot is slowed down in order to ensure the cleaning effect, the cleaning efficiency will be greatly reduced. Summary of the Invention

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, as Figures 1-8As shown, the photovoltaic panel intelligent cleaning robot includes a robot shell 1, a fixing component 2 inside the robot shell 1 for stabilizing the robot shell 1 on the surface of the photovoltaic panel, a first power motor 3 mounted on the upper side of the robot shell 1, and moving components 4 on the left and right sides of the robot shell 1 for moving the robot shell 1 on the photovoltaic panel. A scraping heat-conducting component 5 is located on the right side inside the robot shell 1. The scraping heat-conducting component 5 includes a flow guide box 501 fixed inside the robot shell 1. A water storage tank 502 is fixed to the upper side of the robot shell 1. The front and rear sides of the water storage tank 502 are connected to the flow guide box 501 via flow guide pipes 503. A baffle is installed inside the flow guide box 501, dividing it into upper and lower cavities. Heat-conducting oil is placed in the lower cavity of the flow guide box 501. A pair of flow guide pipes 503 are arranged in a wave-like pattern within the lower cavity of the flow guide box 501. The wave-like distribution of the heat-conducting oil and flow guide pipes increases the heat transfer of the cleaning water. The upper rotating part is connected to evenly distributed heat-conducting scrapers 504. These scrapers 504 increase the residence time of cleaning water on the photovoltaic panel surface, soaking and softening the dirt, and scraping it off. Simultaneously, they conduct heat from the photovoltaic panel surface into the flow guide box 501. The projections of a set of heat-conducting scrapers 504 on the long side of the flow guide box 501 always intersect, ensuring consistent scraping effectiveness on the photovoltaic panel surface. Each pair of adjacent heat-conducting scrapers 504 rotates... The robot housing 1 is equipped with a synchronizing rod 505. A connecting cylinder 506 connected to a pair of guide pipes 503 is fixed inside the flow box 501. A cleaning component 6 is installed inside the robot housing 1. The cleaning component 6 is used to clean dirt on the photovoltaic panel. A water stain removal mechanism 7 is installed inside the robot housing 1. The water stain removal mechanism 7 is used to scrape off and dry the cleaning water on the photovoltaic panel. A control module 9 is installed on the upper side of the robot housing 1. The control module 9 is electrically connected to the first power motor 3, the moving component 4 and the water stain removal mechanism 7 respectively.

[0033] When using this intelligent photovoltaic panel cleaning robot to clean photovoltaic panels, the operator first places the robot shell 1 on the left side of the photovoltaic panel. Then, the operator stabilizes the robot shell 1 on the photovoltaic panel using the fixing component 2. Next, the control module 9 controls the first power motor 3 and the moving component 4 to start. The moving component 4 drives the robot shell 1 to move uniformly to the right on the photovoltaic panel. The robot shell 1 drives the flow guide box 501 to move to the right, which in turn drives a set of heat-conducting scrapers 504 to move to the right. The foremost heat-conducting scraper 504 tilts synchronously with the rest of the scrapers via the synchronizing rod 505. The greater the tilt angle of the heat-conducting scraper 504, the more perpendicular it is to the flow guide box 501. The greater the tilt angle of the heat-conducting scraper 504 relative to the flow guide box 501, the longer the cleaning water stays on the inclined surface of the heat-conducting scraper 504, allowing the cleaning water to soak and soften the dirt on the photovoltaic panel, thus improving the subsequent scraping and cleaning effect. The water storage tank 502 stores... Cleaning water is supplied by the water storage tank 502, which flows through the guide pipes 503 on both the front and rear sides into the guide box 501. The guide pipes 503 are arranged in a wave-like pattern in the lower cavity of the guide box 501 to increase the heat conduction of the cleaning water. The heat-conducting scraper 504 conducts the heat from the surface of the photovoltaic panel into the guide box 501, reducing the temperature difference between the cleaning water in the guide box 501 and the photovoltaic panel, thus avoiding the effect of thermal expansion and contraction of the photovoltaic panel caused by the temperature difference. The cleaning water in the guide box 501 flows to the cleaning component 6. The output belt of the first power motor 3 drives the cleaning component 6 to rinse and scrub the photovoltaic panel with water. At the same time, the output of the first power motor 3 drives the water stain removal mechanism 7 through the pulley belt to first scrape off the cleaning water from the photovoltaic panel and then air dry it until the moving component 4 moves the robot shell 1 to the far right of the photovoltaic panel. The operator controls the first power motor and the moving component 4 to stop through the control module 9, and then controls the fixing component 2 to release the robot shell 1 from the photovoltaic panel. This completes the cleaning of the photovoltaic panel.

[0034] Example 2, based on Example 1, such as Figures 1-5 As shown, the fixing component 2 includes a first oil tank 201 fixed to the upper side of the robot shell 1. A push rod 202 is slidably connected inside the first oil tank 201. A rotating handle 203, which is threadedly connected to the first oil tank 201, is rotatably connected to the push rod 202. A second oil tank 204 is fixed to each of the four corners of the robot shell 1. The first oil tank 201 and each second oil tank 204 are connected by a hose. A corner wheel base 205, which is slidably connected to the robot shell 1, is slidably connected inside each second oil tank 204. A fixed corner wheel 206 is fixed to each corner wheel base 205 for stabilizing the robot shell 1 on the side of the photovoltaic panel.

[0035] When the operator stabilizes the robot shell 1 on the photovoltaic panel using the fixing component 2, the operator places the robot shell 1 on the sunlit surface of the photovoltaic panel and then rotates the rotating handle 203. As the rotating handle 203 rotates, it also moves downward. The rotating handle 203 drives the push rod 202 to slide downward in the first oil tank 201. Under the pressure of the push rod 202, the hydraulic pressure inside the first oil tank 201 increases, causing the first oil tank 201 to squeeze hydraulic oil through the hose to the second oil tanks 204 fixed inside the four corners of the robot shell 1. The hydraulic pressure inside the second oil tank 204 increases, causing the second oil tank 204 to push the corner wheel base 205 to move. The corner wheel base 205 drives the fixed corner wheels 206 to move. The two fixed corner wheels 206 on the front side of the robot shell 1 move backward, and the two fixed corner wheels 206 on the rear side of the robot shell 1 move forward. The four fixed corner wheels 206 clamp the front and rear sides of the photovoltaic panel, so that the lower side of the robot shell 1 faces the upper side of the photovoltaic panel.

[0036] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 13 As shown, the moving component 4 includes a second power motor 401 fixed to the rear side of the robot shell 1. The second power motor 401 is electrically connected to the control module 9. The output end of the second power motor 401 is fixed to a power shaft 402 rotatably connected to the robot shell 1. Evenly distributed power wheels 403 are fixed to the power shaft 402. A driven shaft 404 is rotatably connected to the robot shell 1. Evenly distributed driven wheels 405 are fixed to the driven shaft 404. This is used to drive the robot shell 1 to move on the photovoltaic panel, while keeping the scraping heat conduction component 5 and the cleaning component 6 parallel to and uniformly cleaning the surface of the photovoltaic panel.

[0037] When using this intelligent photovoltaic panel cleaning robot to clean photovoltaic panels, the operator controls the first power motor 3 and the second power motor 401 to start through the control module 9. The output end of the second power motor 401 drives the power shaft 402 to rotate counterclockwise. The power shaft 402 drives the evenly distributed power wheels 403 to rotate counterclockwise. The power wheels 403, through counterclockwise rotation and friction with the photovoltaic panel, drive the robot shell 1 to move to the right. The driven wheels 405, evenly distributed on the driven shaft 404, contact the photovoltaic panel to keep the working surface of the lower side of the robot shell 1 parallel to the upper side of the photovoltaic panel, so that the scraping heat conduction component 5 and the cleaning component 6 can keep the surface of the photovoltaic panel parallel and uniformly cleaned.

[0038] like Figure 2 , Figure 3 and Figures 6-8As shown, the cleaning component 6 includes a cleaning housing 601 fixed to the robot housing 1. A first pulley 602 is rotatably connected to the rear side of the robot housing 1 and connected to the output shaft of the first power motor 3 via a pulley belt. A cleaning roller shaft 604 is fixedly connected to the first pulley 602. The cleaning roller shaft 604 is rotatably connected inside the robot housing 1. A pair of cleaning water supply pipes 603 on the front and rear sides are rotatably connected to the front and rear ends of the cleaning roller shaft 604, respectively. The pair of cleaning water supply pipes 603 on the front and rear sides are connected to the upper cavity of the guide box 501 to provide cleaning water to the cleaning roller shaft 604. The cleaning roller shaft 604 is provided with evenly distributed water outlets and cleaning brushes for uniformly cleaning the surface of the photovoltaic panel.

[0039] When cleaning the photovoltaic panel by scraping off the heat-conducting component 5 and the cleaning component 6, the water storage tank 502 contains cleaning water. The cleaning water in the water storage tank 502 flows to the upper cavity of the guide box 501 through the guide pipes 503 on both the front and rear sides. The guide pipes 503 then flow the cleaning water through the connecting cylinder 506 to the upper cavity of the guide box 501. Afterward, the cleaning water in the upper cavity of the guide box 501 flows to the cleaning roller 604 through the cleaning water supply pipe 603. The output shaft of the first power motor 3 drives the first pulley 602 to rotate counterclockwise via a belt. The pulley 602 drives the cleaning roller 604 to rotate counterclockwise. The cleaning roller 604 drives the evenly distributed water outlets and cleaning brushes on it to brush the photovoltaic panel counterclockwise. The cleaning shell 601 surrounds the upper side of the cleaning roller 604 to prevent the cleaning water from splashing. At the same time, under the guidance of the cleaning shell 601, the cleaning roller 604 transfers the cleaning water to the right between the heat-conducting scrapers 504. The inclined surface of the heat-conducting scrapers 504 increases the retention time of the cleaning water, allowing the cleaning water to soak and soften the dirt on the photovoltaic panel, improving the effect of subsequent scraping and cleaning.

[0040] like Figure 9 and Figure 10As shown, the water stain removal mechanism 7 includes a second pulley 701 rotatably connected to the rear side of the robot shell 1. The second pulley 701 is connected to the output end of the first power motor 3 via a pulley belt. A first drive shaft 702 rotatably connected to the second pulley 701 is fixed to the second pulley 701 and rotatably connected to the inside of the robot shell 1. A second drive shaft 703 is rotatably connected inside the robot shell 1. A conveyor belt 704 with evenly distributed ventilation holes is wound between the first drive shaft 702 and the second drive shaft 703. Several sets of flexible scrapers 705 distributed circumferentially are rotatably connected to the conveyor belt 704. Each set of flexible scrapers 705 forms a local layer. The flexible scrapers 705 are stacked and have gaps between adjacent ones to remove the cleaning water after cleaning the photovoltaic panel surface. A fan 706, which is electrically connected to the control module 9, is fixed to the front of the robot shell 1. An air duct 707 is fixed inside the robot shell 1. The air outlet of the fan 706 is connected to the air duct 707. The air outlet on the air duct 707 is located between the conveyor belts 704 to dry the remaining cleaning water after scraping the photovoltaic panel surface. An adjustment component is provided inside the conveyor belt 704 to adjust the tilt angle of the flexible scrapers 705 according to the angle of the photovoltaic panel.

[0041] like Figure 11 and Figure 12 As shown, the adjustment assembly includes a counterweight slider 708 slidably connected inside the robot housing 1. A return spring is fixed between the front side of the counterweight slider 708 and the robot housing 1. Adjusting rods 709, the same number as the flexible scrapers 705, are slidably connected inside the conveyor belt 704. The counterweight slider 708 is provided with a limiting groove that cooperates with the limiting of the adjusting rods 709. Each adjusting rod 709 is slidably connected with a limiting rotating rod 710. Each limiting rotating rod 710 is fixedly connected to the corresponding flexible scraper 705, which is used to adjust the tilt of the flexible scraper 705 according to the size of the photovoltaic panel's inclination, so as to keep the scraping time of cleaning water on photovoltaic panels with different inclinations stable. A connecting rod 711 is fixedly connected to the lower side of the counterweight slider 708. The rear end of the connecting rod 711 is rotatably connected to the frontmost heat-conducting scraper 504, which is used to keep the residence time of cleaning water on photovoltaic panels with different inclinations stable, and to maintain a stable cleaning water retention soaking and softening effect.

[0042] When the water-removing mechanism 7 scrapes off the cleaning water and dries the cleaned photovoltaic panel, the output end of the first power motor 3 drives the second pulley 701 to rotate counterclockwise. The second pulley 701 drives the first drive shaft 702 to rotate counterclockwise. The first drive shaft 702 drives the second drive shaft 703 to rotate counterclockwise via the conveyor belt 704. The flexible scraper 705 on the lower side of the conveyor belt 704 moves to the right to scrape off the cleaning water from the photovoltaic panel. Through the local layered distribution of the flexible scrapers 705, the flexible scrapers 705 adjacent to the photovoltaic panel are distributed obliquely to the left layer by layer from back to front, so that the flexible scrapers 705 scrape off the cleaning water on the surface of the photovoltaic panel layer by layer from back to front, thereby achieving the function of removing residual moisture and improving the drying rate. Then, the control module 9 controls the process. The blower 706 blows air through the air duct 707, the outlet of which faces the lower side of the drying chain. The air blown out by the air duct 707 flows to the surface of the photovoltaic panel through the ventilation holes on the conveyor belt 704. The airflow passes through the gaps between each pair of adjacent flexible scrapers 705, pushing the water forward while cleaning the water stains, thus accelerating the removal of water. The air blown out by the air duct 707 through the conveyor belt 704 dries the photovoltaic panel, significantly reducing water stains remaining on the photovoltaic panel after cleaning. The evenly distributed flexible scrapers 705 on the conveyor belt 704 limit the airflow blown out by the air duct 707, and the forward-flowing airflow accelerates the evaporation and drying speed. On the inclined photovoltaic panel, the counterweight slider 708... Due to gravity, the counterweight slider 708 slides forward, causing all adjusting rods 709 to move forward. The adjusting rods 709 then move the corresponding limiting rods 710 forward, which in turn cause the corresponding flexible scraper 705 to tilt. A return spring fixed between the counterweight slider 708 and the robot shell 1 causes the counterweight slider 708 to slide different distances depending on the tilt angle of the photovoltaic panel. When the photovoltaic panel tilt angle is large, due to gravity, the counterweight slider 708 slides forward a greater distance, and the adjusting rods 709 cause the flexible scraper 705 to tilt at a larger angle relative to the conveyor belt 704. When the photovoltaic panel tilt angle is small, the counterweight slider 708 slides forward a smaller distance, and the adjusting rods 709 cause the flexible scraper 705 to tilt at a smaller angle. The tilt angle of the flexible scraper 705 is adjusted adaptively according to the tilt angle of the photovoltaic panel. A decrease in the tilt angle of the photovoltaic panel increases the scraping speed of the flexible scraper 705 on the cleaning water, keeping the scraping time of the cleaning water on photovoltaic panels with different tilt angles stable. When the counterweight slider 708 moves the left end of the connecting rod 711 forward, the connecting rod 711 causes the heat-conducting scraper 504 to tilt counterclockwise. The larger the tilt angle of the photovoltaic panel, the shorter the residence time of the cleaning water on its surface. Therefore, when the tilt angle of the photovoltaic panel is small, the tilt angle of the heat-conducting scraper 504 is small; when the tilt angle of the photovoltaic panel is large, the tilt angle of the heat-conducting scraper 504 is large. This increases the residence time of the cleaning water on the heat-conducting scraper 504 according to the increase in the tilt angle of the photovoltaic panel, keeping the residence time of the cleaning water on photovoltaic panels with different tilt angles stable.Maintain a stable supply of clean water for soaking and softening.

[0043] Example 3, based on Example 2, such as Figure 13 and Figure 14 As shown, it also includes a coating assembly 8, which is located on the left side of the robot housing 1. The coating assembly 8 is used to apply an anti-corrosion coating to the photovoltaic panel. The coating assembly 8 includes a paint tank 801 fixed to the robot housing 1. A discharge pipe 802 is rotatably connected inside the robot housing 1. The discharge pipe 802 is provided with circumferentially evenly distributed discharge ports. The front end of the discharge pipe 802 is connected to the paint tank 801 through a flexible hose. Four circumferentially symmetrical distributing baffles are fixed to the discharge pipe 802. 803, the material distribution pipe 804 is slidably connected to four material distribution baffles 803, and four material distribution chambers of the same size are formed between the material distribution pipe 804 and the discharge pipe 802 through the four material distribution baffles 803. The material distribution pipe 804 is provided with coating nozzles evenly distributed in the circumference. A coating roller 805 is fixedly connected to the outer side of the material distribution pipe 804. A third pulley 806 connected to the output end of the first power motor 3 is fixedly connected to the rear end of the material distribution pipe 804. A coating scraper 807 is fixedly connected inside the robot shell 1.

[0044] After the water-removing mechanism 7 scrapes and dries the photovoltaic panels, the output belt of the first power motor 3 drives the third pulley 806 to rotate clockwise. The third pulley 806 drives the distribution pipe 804 to rotate clockwise. The coating material in the paint chamber 801 flows through the hose to the discharge pipe 802. The discharge pipe 802 discharges the coating material outward through evenly distributed discharge ports. The coating material is distributed in the four distribution chambers formed between the discharge pipe 802, the distribution baffle 803, and the distribution pipe 804. 4. When the coating material flows clockwise from the paint inlet to the corresponding dispensing chamber, the coating material flows from the paint inlet of the dispensing pipe 804 into the coating roller 805. The dispensing pipe 804 drives the coating roller 805 to rotate clockwise, evenly applying the coating material to the surface of the photovoltaic panel. The discharge pipe 802, the dispensing baffle 803, and the dispensing pipe 804 form a uniform discharge chamber to achieve uniform discharge and coating effect. The coating scraper 807 scrapes the coating applied to the photovoltaic panel by the coating roller 805 again to smooth the newly coated surface. The layers are more evenly distributed. When the robot shell 1 moves to the far right of the photovoltaic panel, the operator controls the second power motor 401 to stop via the control module 9, the robot shell 1 stops moving, and the first power motor 3 stops, causing the cleaning roller 604 to stop cleaning the photovoltaic panel. The first drive shaft 702 and the second drive shaft 703 stop rotating, causing the conveyor belt 704 to stop driving the flexible scraper 705 to scrape. The fan 706 stops supplying air. Then the operator rotates the rotating handle 203 in the opposite direction. The rotating handle 203 drives the push rod 202 to move upward, reducing the hydraulic pressure inside the first oil tank 201. The second oil tank 204, which is fixed inside the four corners of the robot shell 1, simultaneously squeezes the hydraulic oil into the first oil tank 201. The second oil tank 204 pulls the corner wheel base 205 to reset, and the four fixed corner wheels 206 release the clamping on the front and rear sides of the photovoltaic panel, allowing the robot shell 1 to release from the stable state of the photovoltaic panel. Then the operator removes the robot shell 1, thus completing the cleaning of the upper side of the photovoltaic panel.
