Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel remote sensing cleaning technology, specifically to a photovoltaic panel remote sensing cleaning device and cleaning method. Background Technology

[0002] With the increasing global demand for renewable energy, solar photovoltaic (PV) power generation systems are widely used due to their environmentally friendly and sustainable characteristics. As a key component of solar power generation systems, the surface cleanliness of PV panels directly affects photoelectric conversion efficiency. However, during long-term outdoor operation, PV panels easily accumulate various types of dirt, including dust, sand, and bird droppings. These dirt significantly reduce the light transmittance of the PV panels, thus affecting power generation efficiency.

[0003] Existing methods of manual cleaning are not only costly but also inefficient. Furthermore, manual cleaning poses safety hazards for large-scale photovoltaic power plants or photovoltaic panels installed at high locations. While fixed automatic water spray cleaning can achieve a degree of automation, this method consumes a large amount of water and has limited effectiveness in cleaning different types of stains. Especially in water-scarce areas, this method has poor sustainability. Mechanical scrubbing, while providing strong cleaning power, can easily cause physical damage to the surface of the photovoltaic panels, affecting their lifespan. Summary of the Invention

[0007] A pressurized cleaning section is provided in the middle section of the bottom of the assembly housing. The pressurized cleaning section can work with the swing cleaning component to remove stains that are not easy to remove. A cleaning liquid dispensing component is installed on the surface of the pressurized cleaning section. An air sweeping component is installed at the bottom of the assembly housing and at the bottom of the pressurized cleaning section to blow away floating dust. The air sweeping component uses airflow to pre-remove floating dust from the surface of the photovoltaic panel.

[0008] Preferably, a battery unit is mounted on the left side of the drone body surface, a propeller is mounted on the outer side of the end of the drone body, a frame for supporting the drone body is mounted on the bottom of the drone body, and mounting housings are mounted on both the left and right ends of the frame surface.

[0009] Preferably, the pressurized cleaning unit includes a spray gun located below the assembly housing, and the output end of the nozzle is connected to the nozzle assembly. A support plate is mounted on the surface of the spray gun, and a water supply pipe is connected to the surface of the spray gun and one side of the support plate. The inlet pipe of the water supply pipe is connected to the output end of the water pump.

[0010] Preferably, a plug-in push rod is provided through one end of the inner cavity of the spray gun, and one end of the plug-in push rod extends into the inner cavity of the liquid storage cylinder and is connected to a push plate. At the same time, a liquid storage cylinder is mounted on the end of the liquid storage cylinder located on the surface of the liquid storage cylinder, and the liquid outlet end of the liquid storage cylinder is connected to the surface of the spray gun through a pipeline.

[0011] Preferably, a toggle shaft is installed on one side of the two support plates facing each other. The surface of the toggle shaft is fitted with a toggle plate, and the other end of the toggle plate is provided with a push plate. The surface of the push plate is provided with a slider, and the inner cavity of the slider is provided with a sliding groove.

[0012] Preferably, a sliding plate is installed at the bottom of the push plate, wherein the other end of the sliding plate is connected to a toothed plate, and the toothed plate is meshed with a gear. A gear transmission shaft is fixedly connected to the inner surface of the gear, and the gear transmission shaft extends to the inner cavity of the spray gun and is connected to a baffle. Both the upper and lower ends of the baffle are provided with pressure plates, and multiple water delivery holes are opened on the surfaces of the pressure plates and the baffle.

[0013] Preferably, an air sweeping assembly is installed at the bottom of the frame surface, and the air sweeping assembly includes a push rod and a rotating shaft. The output end of the push rod is connected to a toothed plate, and the surface of the rotating shaft is fitted with a gear that engages with the toothed plate.

[0014] Preferably, a fixed shaft is mounted on the surface of the rotating shaft, wherein the end of the fixed shaft away from the rotating shaft is connected to a jet pipe, and the output end of the jet pipe is connected to a jet head.

[0015] Preferably, an air pump is provided above the push rod, and the output end of the air pump is connected to an air blowing pipe, while the surface of the rotating shaft is connected to a feed pipe.

[0016] On the other hand, the present invention also provides a method for remote sensing cleaning of photovoltaic panels, comprising the following steps:

[0017] S1. When dealing with dust and fallen leaves with low adhesion to the photovoltaic panel surface, operate the air pump to direct airflow through the air blowing pipe into the rotating shaft, and use the air jet head to blow away the dust on the photovoltaic panel surface.

[0018] S2. When removing stubborn stains on the surface of the photovoltaic panel, the drive motor is operated, which is driven by the transmission shaft, and then the support plate is controlled to drive the atomizing nozzle to swing.

[0019] S3. When the atomizing nozzle is oscillating under force, the water pump is controlled to draw the liquid in the water storage tank into the water supply pipe, and spray it outward in an arc shape through the atomizing nozzle to remove stubborn stains on the surface of the photovoltaic panel.

[0020] S4. When removing particularly stubborn stains from the surface of photovoltaic panels, a water pump is used to draw liquid into the spray gun, which is then sprayed out. The pressurized cleaning section is used to remove the stains that are difficult to remove under high pressure.

[0021] S5. When removing particularly stubborn stains in the pressurized cleaning section, the cleaning liquid dispensing component swings under the action of the swing cleaning component, which drives the plug-in push rod and push plate to move, controlling the agent in the storage tank to be injected into the spray gun. The agent is mixed with the cleaning water through the spray gun to form a cleaning solution, which removes strong stains.

[0022] S6. When removing particularly stubborn stains, under the influence of the plug-in push rod, the baffle rotates through the gear transmission shaft, blocking some of the slots on the pressure plate, intermittently increasing the water pressure inside the spray gun, and then removing strong stains through intermittent high pressure of the nozzle.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention uses a drive motor to rotate the transmission shaft, which enables the support plate to swing back and forth, thereby driving the atomizing nozzle to spray cleaning water onto the photovoltaic panel surface. This design not only effectively covers a wider cleaning area and improves cleaning efficiency, but also better adapts to stains of different shapes and sizes, ensuring a more thorough cleaning. The dynamic cleaning method of the swinging cleaning component makes the cleaning process more uniform, avoiding cleaning dead corners that may be caused by spraying in one direction, thereby improving the overall cleaning effect.

[0025] 2. This invention utilizes a spray gun to propel high-pressure water jets, effectively removing stubborn stains, especially those difficult to handle with traditional cleaning methods. The impact of the high-pressure water jets can penetrate even the fine crevices on the photovoltaic panel surface, thoroughly removing dirt. Furthermore, by using a baffle to block the water inlet holes on the booster plate, the water pressure within the spray gun can be flexibly adjusted to meet different cleaning needs. This adjustable high-pressure cleaning method not only improves cleaning effectiveness but also extends the equipment's lifespan and reduces the risk of equipment damage due to excessive water pressure.

[0026] 3. This invention generates airflow through an air pump and uses jet nozzles to pre-blow away floating dust on the surface of photovoltaic panels. Before using cleaning water, the air sweeping component can effectively remove floating dust and light dirt from the surface, reducing the amount of cleaning water used and improving cleaning efficiency. This pre-cleaning function not only saves water resources but also reduces the sewage discharge that may be generated during the cleaning process, achieving the effect of energy saving and environmental protection. The design of the air sweeping component makes the entire cleaning process more efficient and economical, and is suitable for the daily maintenance of large-scale photovoltaic panels.

[0027] 4. This invention intermittently adds cleaning fluid to the spray gun via a cleaning fluid dispensing component, significantly enhancing the removal of particularly stubborn stains and ensuring thorough cleaning. The addition of cleaning fluid softens and breaks down stubborn stains, making them easier to wash away by the high-pressure water jet. Furthermore, the intermittent dispensing method allows for precise control of the amount of cleaning fluid used, avoiding waste. This dispensing mechanism not only improves cleaning effectiveness but also reduces cleaning costs, making the entire cleaning process more economical and environmentally friendly.

[0028] Ultimately, when the oscillating cleaning unit, pressurized cleaning section, air sweeping unit, and cleaning fluid dispensing unit are used in combination, a highly efficient, energy-saving, and environmentally friendly remote sensing cleaning solution for photovoltaic panels can be formed. This device can effectively handle various types of stains, from light dust to heavy stubborn stains, and significantly reduce reliance on water and cleaning agents during the cleaning process, improving overall cleaning efficiency while reducing operating costs. The pre-cleaning function of the air sweeping unit reduces the amount of water used in subsequent cleaning, the dynamic cleaning method of the oscillating cleaning unit ensures uniformity and thoroughness of cleaning, the high-pressure water flow of the pressurized cleaning section can deeply remove stubborn stains, and the intermittent dispensing of cleaning fluid from the cleaning fluid dispensing unit further enhances the cleaning effect. This makes it highly flexible and maintainable, easy to adjust and optimize according to different application scenarios, thereby meeting diverse cleaning needs. Attached Figure Description

[0055] Please see Figures 1-14 A photovoltaic panel remote sensing cleaning device includes an unmanned aerial vehicle (UAV) 100 and a water storage tank 110. An assembly shell 150 is installed below the UAV 100. A battery unit 120 is installed on the left side of the UAV 100 surface, providing power to the entire remote sensing cleaning device. Multiple propellers 130 are installed on the outer side of the ends of the UAV 100, each controlled by an independent drive unit to control the flight of the remote sensing cleaning device. The UAV 100 can be an ATUAV multi-rotor aircraft or a Maiyouwei ZW1 series remote sensing UAV. The product is equipped with a 4K high-definition camera, millimeter-wave radar, a flight control system, and color flashing outline lights to ensure flight stability and safety. A frame 160 is installed below the UAV 100 to support the entire device. Supplemental lighting units 140 are installed on both the left and right ends of the frame 160 surface to provide supplemental lighting to the surrounding environment in low-light conditions.

[0056] A water pump 600 is bolted to the top of the housing 150. The input end of the water pump 600 is connected to the output end of the water storage tank 110, and the output end of the water pump 600 is connected to a water delivery pipe 610. The outlet end of the water delivery pipe 610 is connected to an atomizing nozzle 620. The surface of the water delivery pipe 610 is movably fastened to the support plate 220 by a snap-fit, and the snap-fit ​​limits the water delivery pipe 610. The water delivery pipe 610 consists of a fixed pipe and a telescopic hose.

[0057] A swing cleaning assembly 200 for swing cleaning is provided at both the front and rear ends of the assembly housing 150. Each swing cleaning assembly 200 includes a drive motor 210 for power output. The drive motor 210 is bolted to the inner cavity of the assembly housing 150. Both the front and rear ends of the drive motor 210 are provided with drive shafts 211, which extend through to the outside of the assembly housing 150 and rotatably contact its connection point. The output end of the drive motor 210 is connected to the shaft end of the adjacent drive shaft 211. Therefore, the drive motor 210... 10 drives the transmission shaft 211 to rotate. The shaft ends of the two transmission shafts 211 on opposite sides are fitted with connecting plates 212. The other end of the connecting plate 212 is rotatably connected to a guide plate 221. The other end of the guide plate 221 is rotatably connected to a support plate 220. The end of the support plate 220 is rotatably connected to the outside of the assembly housing 150. In this way, the output end of the support plate 220 is controlled to rotate in both directions. When the transmission shaft 211 is subjected to force and rotates, the connecting plate 212 can drive the guide plate 221 to move the support plate 220 to swing back and forth.

[0058] Finally, when the support plate 220 swings, it can pull the water pipe 610 and the atomizing nozzle 620 to swing left and right, thereby driving the atomizing nozzle 620 to swing and spray cleaning water on the surface of the photovoltaic panel to clean the surface of the photovoltaic panel.

[0059] A pressurized cleaning section 300 is provided in the middle section of the bottom of the assembly housing 150; the pressurized cleaning section 300 can cooperate with the oscillating cleaning component 200 to remove stains that are difficult to remove and have strong adhesion; the pressurized cleaning section 300 includes a spray gun 310, which is located below the assembly housing 150, and the output end of the nozzle component 311 is connected to the nozzle component 311, wherein, in order to fix and limit the spray gun 310, such as Figure 11 As shown, a support plate 330 is mounted on the surface of the spray gun 310, and the end of the support plate 330 is connected to the bottom of the assembly housing 150. A water supply pipe 320 is connected to the surface of the spray gun 310 and to one side of the support plate 330; and the inlet pipe of the water supply pipe 320 is connected to the output end of the water pump 600.

[0060] Specifically, one end of the water supply pipe 320 extends in an L-shape into the inner cavity of the spray gun 310, and its output direction is the same as that of the spray gun 310. The spray gun 310 is located on one side of the push plate 530 and performs unidirectional water flow treatment. If a one-way valve body is installed, it will prevent the water from flowing to the end of the spray gun 310 away from the nozzle 311 due to excessive pressure.

[0061] Therefore, the water pump 600 can draw clean water from the water storage tank 110, introduce it into the spray gun 310 through the water delivery pipe 320, and spray it out through the nozzle 311 to clean the surface of the photovoltaic panel.

[0062] A cleaning liquid dispensing assembly 500 is installed on the surface of the pressurized cleaning unit 300. The cleaning liquid dispensing assembly 500, in conjunction with the pressurized cleaning unit 300, not only allows for intermittent dispensing of cleaning agent but also pressurizes the pressurized cleaning unit 300, thereby increasing its effectiveness in removing strong stains; for example... Figure 11 As shown, a push rod 520 is inserted through one end of the inner cavity of the spray gun 310, and one end of the push rod 520 extends into the inner cavity of the liquid storage cylinder 510 and is connected to a push plate 530. Meanwhile, a liquid storage cylinder 510 is mounted on the end of the liquid storage cylinder 510 located on its surface, and the outlet end of the liquid storage cylinder 510 is connected to the surface of the spray gun 310 via a pipeline. Under the action of the push plate 530, the outlet of the liquid storage cylinder 510 can be blocked, while the push rod 520 can... As the support plate 330 moves, the plug-in push rod 520 can move linearly, which in turn pushes the push plate 530 to remove the blocking state of the liquid outlet of the liquid storage cylinder 510, so that the cleaning liquid in the liquid storage cylinder 510 can flow into the spray gun 310. Then, as the water in the spray gun 310 flows towards the nozzle 311, the cleaning water containing the cleaning agent is sprayed outward through the nozzle 311 to remove the stains with strong adhesion on the surface of the photovoltaic panel.

[0063] Furthermore, to provide auxiliary support for the plug-in push rod 520, a push rod fixing plate 521 is movably sleeved on the surface of the plug-in push rod 520, and the push rod fixing plate 521 is fastened to the bottom of the assembly housing 150 by bolts. The connection between the push rod fixing plate 521 and the plug-in push rod 520 is in sliding contact.

[0064] A toggle shaft 540 is installed on one side of the two support plates 220. A toggle plate 541 is sleeved on the surface of the toggle shaft 540, and a push plate 550 is provided at the other end of the toggle plate 541. The push plate 550 is sleeved on the surface of the plug-in push rod 520. A slider 552 is provided on the surface of the push plate 550, and a groove 551 is slidably provided in the inner cavity of the slider 552. The groove 551 is fixedly connected to the opposite side of the toggle plate 541.

[0065] A sliding plate 561 is installed at the bottom of the push plate 550. A toothed plate 560 is connected to the other end of the sliding plate 561, and the toothed plate 560 is meshed with a gear 570. A gear transmission shaft 571 is fixedly connected to the inner surface of the gear 570, and the gear transmission shaft 571 extends into the inner cavity of the spray gun 310 and is connected to a baffle 590. The connection between the gear transmission shaft 571 and the spray gun 310 is movably connected by a sealed bearing. Pressure plates 580 are provided at both the upper and lower ends of the baffle 590. Multiple water delivery holes 581 are opened on the surfaces of both the pressure plates 580 and the baffle 590. The water delivery holes 581 on the baffle 590 and the water delivery holes 581 on the inner ring of the pressure plates 580 are interconnected, allowing... Liquid can flow out through the spray gun 310 and the nozzle 311. When the support plate 220 swings, it can drive the actuating shaft 540 and the actuating plate 541 to push the push plate 550 to move, thereby changing the position of the plug-in push rod 520. Then, the sliding plate 561 pushes the toothed plate 560 to rotate the gear 570, so that the gear 570 drives the gear transmission shaft 571 and the baffle 590 to rotate. When the rotation reaches a certain angle, the baffle 590 blocks the water supply hole 581 opened in the inner ring of the pressure plate 580, reducing the flow rate and increasing the fluid pressure in the spray gun 310. Then, the high pressure is sprayed out through the nozzle 311, and together with the liquid, it removes the stains with strong adhesion on the surface of the photovoltaic panel.

[0066] An air-sweeping assembly 400 for blowing away floating dust is installed at the bottom of the housing 150 and at the bottom of the pressurized cleaning section 300. The air-sweeping assembly 400 uses airflow to pre-remove floating dust from the surface of the photovoltaic panel, reducing the input of cleaning water. The air-sweeping assembly 400 is also installed at the bottom of the surface of the frame 160. The air-sweeping assembly 400 includes a push rod 410 and a rotating shaft 430. One end of the push rod 410 is equipped with a supporting shaft 411, and the shaft end of the supporting shaft 411 is connected to the frame 160. The surface of the 60 is connected, thereby using the support shaft 411 to provide auxiliary support for the push rod 410. The rotating shaft 430 is rotatably mounted on the frame 160, and the output end of the push rod 410 is connected to the toothed plate 420. The surface of the rotating shaft 430 is fitted with a gear 421 that engages with the toothed plate 420. Therefore, when the push rod 410 is working, its output end can drive the toothed plate 420 to move, and then drive the gear 421 to rotate the rotating shaft 430.

[0067] A fixed shaft 431 is mounted on the surface of the rotating shaft 430. The end of the fixed shaft 431 away from the rotating shaft 430 is connected to a jet pipe 440, and the output end of the jet pipe 440 is connected to a jet head 441. The rotating shaft 430, the fixed shaft 431, the jet pipe 440, and the inner cavity of the jet head 441 are interconnected to form an air supply and water supply channel. Airflow and waterflow can be output through the jet head 441. Therefore, the jet head 441 can be used to blow dust off the surface of the photovoltaic panel, and water can also be sprayed to remove dust.

[0068] An air pump 450 is installed above the push rod 410 and is mounted inside the housing 150. The output end of the air pump 450 is connected to an air blowing pipe 451, and the other end of the air blowing pipe 451 is connected to the inner cavity of the rotating shaft 430. The surface of the rotating shaft 430 is connected to a feed pipe 460, and the input end of the feed pipe 460 is connected to the output end of the water pump 600. Therefore, water is supplied to the jet nozzle 441 by the water pump 600 and air is supplied to the jet nozzle 441 by the air pump 450, so that the jet nozzle 441 can spray both water and air, thereby efficiently removing dust from the surface of the photovoltaic panel.

[0069] Control valves are installed on the surfaces of all pipelines involved in the remote sensing cleaning device, and the feed pipe 460 and the air blowing pipe 451 are composed of fixed pipes and telescopic hoses; this is to prevent the feed pipe 460 and the air blowing pipe 451 from affecting the rotation of the rotating shaft 430.

[0070] Specifically, the working principle of the photovoltaic panel remote sensing cleaning device is as follows: the air pump 450 is operated to blow air into the rotating shaft 430 through the air blowing pipe 451, and the air nozzle 441 blows away the floating dust on the surface of the photovoltaic panel; when removing stubborn stains on the surface of the photovoltaic panel, the drive motor 210 is operated, which is driven through the transmission shaft 211, and then controls the support plate 220 to drive the atomizing nozzle 620 to swing; at the same time, the water pump 600 is controlled to draw the liquid in the water storage tank 110 into the water supply pipe 610, and spray it outward in an arc shape through the atomizing nozzle 620 to remove stubborn stains on the surface of the photovoltaic panel.

[0071] When removing particularly stubborn stains from the surface of photovoltaic panels, a water pump 600 draws liquid into the spray gun 310, which then sprays it out. The pressurized cleaning unit 300 uses high pressure to remove stains that are difficult to remove. At the same time, the cleaning liquid dispensing component 500 is oscillated by the oscillating cleaning component 200, which drives the plug-in push rod 520 and the push plate 530 to move, controlling the agent in the liquid storage cylinder 510 to be dispensed into the spray gun 310. The agent is mixed with the cleaning water in the spray gun 310 to form a cleaning solution, which removes strong stains. Furthermore, under the influence of the plug-in push rod 520, the toothed shaft rod 571 drives the baffle 590 to rotate, blocking some of the slots on the pressure plate 580, intermittently increasing the water pressure in the spray gun 310, and then intermittently removing strong stains through the nozzle component 311 under high pressure.

[0072] A method for remotely sensing and cleaning photovoltaic panels includes the following steps:

[0073] S1. When facing dust and fallen leaves with low adhesion to the photovoltaic panel surface, operate the air pump 450 to flow the airflow into the rotating shaft 430 through the air blowing pipe 451, and use the air jet head 441 to blow the dust on the photovoltaic panel surface.

[0074] S2. When removing stubborn stains on the surface of the photovoltaic panel, the drive motor 210 is operated and driven by the transmission shaft 211, which in turn controls the support plate 220 to drive the atomizing nozzle 620 to swing.

[0075] S3. When the atomizing nozzle 620 is oscillating under force, the water pump 600 is controlled to draw the liquid in the water storage tank 110 into the water supply pipe 610, and spray it outward in an arc shape through the atomizing nozzle 620 to remove stubborn stains on the surface of the photovoltaic panel.

[0076] S4. When removing particularly stubborn stains from the surface of photovoltaic panels, the water pump 600 is used to pump liquid into the spray gun 310, and the liquid is sprayed out through the spray gun 310. The pressurized cleaning unit 300 is used to remove the stains that are not easy to remove under high pressure.

[0077] S5. When the pressurized cleaning unit 300 removes particularly stubborn stains, the cleaning liquid dispensing component 500 is oscillated by the oscillating cleaning component 200, which drives the plug-in push rod 520 and push plate 530 to move, controlling the agent in the liquid storage cylinder 510 to be injected into the spray gun 310. The agent is mixed with the cleaning water through the spray gun 310 to form a cleaning solution, which removes strong stains.

[0078] S6. When removing particularly stubborn stains, under the influence of the plug-in push rod 520, the baffle 590 is rotated through the gear transmission shaft 571 to block some of the slots on the pressure plate 580, intermittently increasing the water pressure in the spray gun 310, and then the strong stains are removed by intermittent high pressure through the nozzle 311.

[0079] In summary, the present invention achieves the following functions and effects:

[0080] 1. This invention uses a drive motor to rotate the transmission shaft, which enables the support plate to swing back and forth, thereby driving the atomizing nozzle to spray cleaning water onto the photovoltaic panel surface. This design not only effectively covers a wider cleaning area and improves cleaning efficiency, but also better adapts to stains of different shapes and sizes, ensuring a more thorough cleaning. The dynamic cleaning method of the swinging cleaning component makes the cleaning process more uniform, avoiding cleaning dead corners that may be caused by spraying in one direction, thereby improving the overall cleaning effect.

[0081] 2. This invention utilizes a spray gun to propel high-pressure water jets, effectively removing stubborn stains, especially those difficult to handle with traditional cleaning methods. The impact of the high-pressure water jets can penetrate even the fine crevices on the photovoltaic panel surface, thoroughly removing dirt. Furthermore, by using a baffle to block the water inlet holes on the booster plate, the water pressure within the spray gun can be flexibly adjusted to meet different cleaning needs. This adjustable high-pressure cleaning method not only improves cleaning effectiveness but also extends the equipment's lifespan and reduces the risk of equipment damage due to excessive water pressure.

[0082] 3. This invention generates airflow through an air pump and uses jet nozzles to pre-blow away floating dust on the surface of photovoltaic panels. Before using cleaning water, the air sweeping component can effectively remove floating dust and light dirt from the surface, reducing the amount of cleaning water used and improving cleaning efficiency. This pre-cleaning function not only saves water resources but also reduces the sewage discharge that may be generated during the cleaning process, achieving the effect of energy saving and environmental protection. The design of the air sweeping component makes the entire cleaning process more efficient and economical, and is suitable for the daily maintenance of large-scale photovoltaic panels.

[0083] 4. This invention intermittently adds cleaning fluid to the spray gun via a cleaning fluid dispensing component, significantly enhancing the removal of particularly stubborn stains and ensuring thorough cleaning. The addition of cleaning fluid softens and breaks down stubborn stains, making them easier to wash away by the high-pressure water jet. Furthermore, the intermittent dispensing method allows for precise control of the amount of cleaning fluid used, avoiding waste. This dispensing mechanism not only improves cleaning effectiveness but also reduces cleaning costs, making the entire cleaning process more economical and environmentally friendly.

[0084] Ultimately, when the oscillating cleaning unit, pressurized cleaning section, air sweeping unit, and cleaning fluid dispensing unit are used in combination, a highly efficient, energy-saving, and environmentally friendly remote sensing cleaning solution for photovoltaic panels can be formed. This device can effectively handle various types of stains, from light dust to heavy stubborn stains, and significantly reduce reliance on water and cleaning agents during the cleaning process, improving overall cleaning efficiency while reducing operating costs. The pre-cleaning function of the air sweeping unit reduces the amount of water used in subsequent cleaning, the dynamic cleaning method of the oscillating cleaning unit ensures uniformity and thoroughness of cleaning, the high-pressure water flow of the pressurized cleaning section can deeply remove stubborn stains, and the intermittent dispensing of cleaning fluid from the cleaning fluid dispensing unit further enhances the cleaning effect. This makes it highly flexible and maintainable, easy to adjust and optimize according to different application scenarios, thereby meeting diverse cleaning needs.
