[0002] Photovoltaic array refers to a system composed of multiple photovoltaic components such as solar panels arranged in a certain way, which is used to convert solar energy into electrical energy; photovoltaic panels, also known as solar panels, are key equipment for converting solar energy into electrical energy. They directly convert light energy into electrical energy through the photoelectric effect. After the photovoltaic array has been working for a long time, a certain amount of dust may accumulate on the photovoltaic panel, which will block the sunlight, reduce the light intensity of the photovoltaic panel, and lead to a decrease in the power generation effect.

Therefore, the terms describing the orientation or position relationship in the present invention are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood in conjunction with the drawings and according to specific circumstances.

[0033] Embodiment 1:

[0034] See attached Figures 1 to 7 The present invention discloses a photovoltaic panel cleaning device, comprising a main body 1, the main body 1 comprising a shell 101, both sides of the shell 101 are provided with limit frames 102, and the limit frames 102 are provided with driving wheels 103 for driving the shell 101 to move; a pretreatment mechanism 3, the pretreatment mechanism 3 comprising a plurality of dust suction pipes 303 arranged at the front end of the shell 101, a detection component arranged at the front end of the dust suction pipe 303, and an opening adjustment component arranged on the dust suction pipe 303, the opening adjustment component is used to dynamically adjust the suction force of the dust suction pipe 303 according to the detection result of the detection component; a cleaning mechanism 2, the cleaning mechanism 2 comprising a cleaning component 204 arranged in the shell 101, and a position adjustment component 205 arranged between the cleaning component 204 and the shell 101.

[0035] Specifically, the opening adjustment component includes a valve seat 304 arranged on the dust suction pipe 303, a valve block 305 arranged in the valve seat 304, a gear 1 302 arranged on both sides of the dust suction pipe 303, a telescopic rod 1 301 arranged between the gear 1 302 and the valve block 305, and a gear 2 306 arranged on both sides of the dust suction pipe 303, and the gear 1 302 is meshed with the gear 2 306; the detection component includes a roller 1 308, and the two sides of the roller 1 308 are respectively connected to the two gear 2s 306 through a bracket 307.

[0036] Specifically, the cleaning assembly 204 includes a fixing frame 2043 and two cleaning wheels 2041 disposed in the housing 101 . The fixing frame 2043 is provided with a motor 2042 . The output end of the motor 2042 and the input end of the cleaning wheel 2041 are connected via a transmission belt 2044 .

[0037] Specifically, the position adjustment component 205 includes an electric push rod 2048 arranged on the top of the shell 101, a movable seat 2047 arranged at the output end of the electric push rod 2048, a swing arm 1 2045 arranged between the cleaning wheel 2041 and the shell 101, and a swing arm 2046 arranged between the swing arm 1 2045 and the movable seat 2047.

[0038] Specifically, a dust suction seat 203 is provided between the movable seat 2047 and the fixed frame 2043 , a dust suction piece 201 is provided on the top of the shell 101 , and the dust suction piece 201 is connected to the dust suction seat 203 and the dust suction pipe 303 through a hose 202 .

[0039] As can be seen from the above structure, when working, the device is stuck on the photovoltaic panel through the limit frame 102, and the driving wheel 103 can be started to drive the device to automatically walk on the photovoltaic panel. During the walking process, the roller 1 308 will contact the photovoltaic panel to be cleaned in advance. When there are hard particle impurities on the photovoltaic panel, the roller 1 308 will be lifted up by the hard particle impurities after contacting the hard particle impurities, and then swing upward with the gear 2 306 as the axis through the bracket 307. The swing amplitude corresponds to the specifications of the hard particle impurities. When the roller 1 308 swings upward, it will drive the gear 2 306 to rotate synchronously, and then drive the gear 1 302 through meshing. When it rotates in the opposite direction, the rotation of gear 1 302 will drive the valve block 305 to move outward from the valve seat 304 through the telescopic rod 1 301, so as to increase the opening of the valve seat 304, reduce the resistance, increase the suction force of the dust suction pipe 303, and avoid blockage caused by larger granular impurities. Pre-absorbent treatment of hard granular impurities can avoid scratching the photovoltaic panel during subsequent cleaning. After passing over the impurities, the roller 1 308 will fall back to its original position by its own weight, thereby restoring the opening of the valve seat 304 and distributing the suction force generated by the dust suction part 201 to other dust suction pipes 303 that need to absorb larger granular impurities, thereby improving work efficiency and reducing work energy consumption.

[0040] In one embodiment of the present application, roller 308 can be made of rubber tire, and bracket 307 can be made of hollow plastic material with a lighter texture. The outer surface of roller 308 can be provided with anti-skid grooves. When hard granular impurities are not adhered to the photovoltaic panel, the rolling of roller 308 will cause the anti-skid grooves on it to grasp the outer surface of the hard granular impurities, so that while it is subjected to the thrust of roller 308, it is subjected to the axial downward pressure of roller 308 to press the hard granular impurities down on the photovoltaic panel. Combined with its lighter texture, it can easily pass over the impurities and avoid pushing them to move synchronously. At the same time, the dust suction tube 303 is close to the photovoltaic panel. When the hard granular impurities are adhered tightly, they will be pushed down by the dust suction tube 303 when they contact the bottom of the dust suction tube 303. Combined with the increase in the opening of the valve seat 304, the suction force is increased, thereby easily sucking away the hard granular impurities to avoid omissions and ensure the cleaning effect.

[0041] When cleaning, the electric push rod 2048 is started to drive the movable seat 2047 to move downward. During the movement of the movable seat 2047, the swing arm 2046 will push the swing arm 1 2045 to swing downward, thereby driving the two cleaning wheels 2041 to separate and swing synchronously, thereby increasing the cleaning range and making the cleaning wheels 2041 in close contact with the photovoltaic panel to improve the cleaning effect. Then the motor 2042 is started, and the motor 2042 will drive the two cleaning wheels 2041 to rotate synchronously through the transmission belt 1 2044 to clean the upper surface of the photovoltaic panel. During the cleaning process, the dust collector 201 is started, and the dust collected can be concentratedly extracted by the dust collector seat 203. To complete the cleaning of the photovoltaic panel, the electric push rod 2048 drives the cleaning wheel 2041 to swing, which will drive the dust suction seat 203 to move up and down synchronously, ensuring the relative position between the dust suction seat 203 and the cleaning wheel 2041, and ensuring the dust suction effect. After the work is completed, the device can be inverted, water is sprayed on the cleaning wheel 2041, and then the electric push rod 2048 is started to drive the movable seat 2047 to move upward, and then the two cleaning wheels 2041 are driven to swing synchronously until they are in contact and squeezed to squeeze out the adsorbed water together with the residual dust. Repeating this process can complete the cleaning and maintenance of the cleaning wheel 2041 without removing it for manual cleaning, which is convenient for personnel to use.

[0042] Embodiment 2:

[0043] See attached Figures 1 to 7 On the basis of the first embodiment, the photovoltaic panel cleaning device provided in this embodiment further includes a finishing mechanism 4, which includes a storage box 401 disposed at the rear end of the housing 101, a cleaning cloth 402 disposed in the storage box 401, and a renewal component 403 disposed between the cleaning cloth 402 and the housing 101.

[0044] Specifically, Figure 6 As shown, the update component 403 includes a telescopic rod 2 4031 arranged at the rear end of the shell 101, a rack 4034 arranged in the telescopic rod 2 4031, sliders 4033 arranged on both sides of the rack 4034, inclined slide grooves 4032 arranged on both sides of the telescopic rod 2 4031, a roller 2 4035 arranged at the bottom of the telescopic rod 2 4031, a gear 3 4038 arranged in the shell 101, a roller 1 4036 and a roller 2 4037 arranged in the storage box 401, the gear 3 4038 is connected to the roller 1 4036 through a transmission belt 2 4039, and the rack 4034 is meshed with the gear 3 4038.

[0045] Specifically, roller 2 4037 is located at the bottom of roller 1 4036, and the cleaning cloth 402 is connected to roller 1 4036 and roller 2 4037 respectively through tension.

[0046] Specifically, a disassembly plate 4011 is provided at the rear end of the storage box 401 , and a second roller 4037 passes through the storage box 401 and is provided with a threaded block 4012 , and nuts 4013 are threadedly connected to the threaded blocks 4012 on both sides of the storage box 401 .

[0047] It can be seen from the above structure that after cleaning the upper surface of the photovoltaic panel, the dust remaining on the upper surface of the photovoltaic panel can be wiped clean by the cleaning cloth 402 during the movement of the device, thereby improving the cleaning effect. The outer frame of the photovoltaic panel is slightly thicker than the panel body. When the device completes the cleaning of one photovoltaic panel, it will move to the next photovoltaic panel in the photovoltaic array. During the process, when roller 2 4035 contacts the outer frame, it will be lifted up by it. Since the slider 4033 is located at the lowest point of the inclined slide groove 4032, the rack 4034 cannot move downward, and then moves upward under the push of the telescopic rod 2 4031, thereby driving the gear 3 4038 to rotate through the meshing of the rack 4034 and the gear 3 4038. The gear 3 4038 will drive the roller 1 4036 to rotate through the transmission belt 2 4039, and then use the tension and friction to drive the cleaning cloth 402 to move along the rolling direction of the roller 1 4036, and remove the dust contaminated on the cleaning cloth 402. The cleaning cloth 402 is moved into the storage box 401, and the clean cleaning cloth 402 is moved to the contact point with the photovoltaic panel to perform subsequent cleaning work to ensure the cleaning effect. After the roller 2 4035 passes over the outer frame, it will return to its original position by its own gravity, and the rack 4034 will be blocked by the gear 3 4038 after contacting it, and then move obliquely upward under the guidance of the inclined slide 4032, so that the rack 4034 and the gear 3 4038 are separated and the meshing relationship is released. After the slider 4033 slides to the lowest point of the inclined slide 4032, it will mesh with the gear 3 4038 again and block the gear 3 4038 from rotating in the initial direction, so as to realize the unidirectional movement of the cleaning cloth 402 and improve the cleaning effect. Among them, the inclined slide 4032 is adapted to the movement trajectory of the slider 4033.

[0049] See attached Figures 1 to 7 Based on the second embodiment, the present invention further provides a photovoltaic panel cleaning method, using a photovoltaic panel cleaning device in the above embodiment, such as Figure 7 As shown, the following steps are included:

[0051] Step 2: Use the detection component to detect the hard particles on the photovoltaic panel. After detection, according to the specifications of the hard particles, use the opening adjustment component to dynamically adjust the suction force of the dust suction pipe 303 to suck and clean the hard particles;

[0052] Step 3: during the movement of the housing 101, the position adjustment component 205 is activated to make the cleaning component 204 contact with the upper surface of the photovoltaic panel, and the cleaning component 204 is activated to sweep away the dust on the surface of the photovoltaic panel;

[0053] Step 4: Use the cleaning cloth 402 to wipe the surface of the photovoltaic panel after cleaning and extraction, and after completing the cleaning work on one photovoltaic panel, use the update component 403 to replace the cleaning cloth 402 in contact with the photovoltaic panel to clean the next photovoltaic panel in the photovoltaic array.

[0054] It can be seen from the above structure that a photovoltaic panel cleaning method provided by the present invention can clean the photovoltaic panels in the solar photovoltaic array, and the process is: placing the shell 101 on the photovoltaic panel, using the limit frame 102 to clamp on the frames at both ends of the photovoltaic panel, so that the driving wheel 103 contacts the photovoltaic panel frame, and starting the driving wheel 103 to drive the shell 101 to move at a constant speed on the photovoltaic panel; using the bracket 307 to detect the hard particles on the photovoltaic panel, and after detection, using the valve block 305 to adjust the opening of the valve seat 304 according to the specifications of the hard particles, and dynamically adjust the suction The suction force of the dust pipe 303 sucks up and cleans the hard particles; the motor 2042 is started, and the transmission belt 2044 is used to drive the two cleaning wheels 2041 to rotate to sweep the dust on the surface of the photovoltaic panel, and the dust is concentratedly extracted by the dust suction base 203; finally, the surface of the photovoltaic panel after cleaning is wiped clean by the cleaning cloth 402, and after completing the cleaning of one photovoltaic panel, the cleaning cloth 402 in contact with the photovoltaic panel is replaced to clean the next photovoltaic panel in the photovoltaic array, so as to improve the cleaning effect of each photovoltaic panel in the photovoltaic array.
