Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and in particular to an ice and snow processing device for solar photovoltaic panels. Background Art

[0002] In the related art, water vapor in the air condenses into snowflakes under certain conditions, and then naturally falls to the surface of the solar photovoltaic panel by gravity, gradually accumulating to form snow. At the same time, when there is snow on the surface of the solar photovoltaic panel and the ambient temperature continues to be below the freezing point, the snow will gradually begin to freeze and form ice and snow. As time goes by and the temperature continues to drop, the ice layer will continue to thicken;

[0003] When the temperature rises, the accumulated ice and snow gradually melt, and the friction between the accumulated ice and snow and the photovoltaic panels decreases. Under the action of gravity, the accumulated ice and snow in the frozen state slides down in a partial or overall distribution. During this process, the aforementioned condensation nuclei rub against the solar photovoltaic panels, and the surface of the solar photovoltaic panels is scratched and damaged. Even if there are no condensation nuclei, the irregular shape and edges of the ice blocks themselves still exist in the sliding process, causing scratches on the surface of the solar panels. That is, when large-volume ice blocks slide down, under the dual action of gravity and friction, scratches are left on the surface of the solar panels, and even mutual impact is generated between the ice blocks and the solar photovoltaic panels when they slide down, resulting in cracks and damage to the glass on the surface of the solar photovoltaic panels.

[0004] In addition, when snow freezes and melts, it will cause drastic changes in the surface temperature of the solar panels, which will in turn cause the solar photovoltaic panel materials to produce thermal expansion and contraction effects, internal stress changes or local overheating, damage the solar photovoltaic panel cells and packaging materials, and reduce the service life and performance of the solar panels.

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] In the related art, water vapor in the air condenses into snowflakes under certain conditions, and then naturally falls to the surface of the solar photovoltaic panel by gravity, gradually accumulating to form snow. At the same time, when there is snow on the surface of the solar photovoltaic panel and the ambient temperature continues to be below the freezing point, the snow will gradually begin to freeze and form ice and snow. As time goes by and the temperature continues to drop, the ice layer will continue to thicken;

[0044] When the temperature rises, the accumulated ice and snow gradually melt, and the friction between the accumulated ice and snow and the photovoltaic solar panels decreases. Under the action of gravity, the accumulated snow in the frozen state slides down in a partial or overall distribution. During this process, the aforementioned condensation nuclei rub against the solar photovoltaic panels, and the surface of the solar photovoltaic panels is scratched and damaged. Even if there are no condensation nuclei, the irregular shape and edges of the ice blocks themselves still exist in the sliding process, causing scratches on the surface of the solar panels. That is, when large-volume ice blocks slide down, under the dual action of gravity and friction, scratches are left on the surface of the solar panels, and even mutual impact is generated between the ice blocks and the solar photovoltaic panels when they slide down, resulting in cracks and damage to the glass on the surface of the solar photovoltaic panels.

[0045] In addition, when snow freezes and melts, it will cause drastic changes in the surface temperature of the solar panels, which will in turn cause the solar photovoltaic panel materials to produce thermal expansion and contraction effects, internal stress changes or local overheating, damage the solar photovoltaic panel cells and packaging materials, and reduce the service life and performance of the solar panels.

[0046] Reference below Figure 1-Figure 8 An ice and snow handling device 100 for a solar photovoltaic panel according to an embodiment of the present invention is described.

[0047] The ice and snow treatment equipment 100 for solar photovoltaic panels according to the present invention comprises: a substrate 11, an ice-breaking component, an ice-melting component, a cleaning component and a driving component. A power supply board 12 is arranged on the substrate 11, and the power supply board 12 can convert solar energy into electrical energy as auxiliary electrical energy for the ice and snow treatment equipment; at least part of the ice-breaking component is movably arranged on one side of the substrate 11 in the thickness direction, and the ice-breaking component is suitable for dividing and enclosing the ice and snow accumulated in a local area on the surface of the photovoltaic panel and spraying an ice-melting medium on the area; the ice-melting component is arranged on the ice-breaking component, and a receiving cavity is formed in the ice-melting component, and the receiving cavity is suitable for collecting the ice and snow accumulated on the surface of part of the photovoltaic panel, and the ice-melting component is suitable for breaking up and melting the ice and snow in the receiving cavity; the cleaning component is arranged on the ice-breaking component and is connected to the receiving cavity, and the cleaning component is suitable for scraping and wiping the area enclosed by the ice-breaking component to remove excess melted ice and snow and perform drying treatment; the driving component is connected to the substrate 11, and the driving component is suitable for driving the ice-breaking component, the ice-melting component and the cleaning component to move.

[0048] In some specific embodiments, the ice and snow treatment equipment 100 consists of a substrate 11, an ice-breaking component, an ice-melting component, a cleaning component and a driving component. A power supply board 12 is provided on the substrate. The power supply board 12 can convert solar energy into electrical energy as auxiliary power for the ice and snow treatment equipment. The external driving motor drives the driving component to move (during actual operation, the power supply board 12 can provide power supply services to the external driving motor or other electrical components of the equipment). The driving component moves to control the overall movement of the ice-breaking component, the cleaning component and the ice-melting component. During this process, the ice-melting component and the ice and snow accumulate relative to each other, so as to collect the ice and snow on the surface of the photovoltaic panel into the receiving cavity, and break up and melt the ice and snow inside the receiving cavity. The accumulated ice and snow on the photovoltaic panel are initially removed, and then the driving component continues to drive the ice-breaking component to move so that the ice-breaking component contacts the accumulated ice and snow, so as to divide the local area of ​​the photovoltaic panel surface into circles. The ice-breaking component can also spray ice-melting medium to the accumulated ice and snow in the circled area, thereby gradually melting the accumulated ice and snow into water, avoiding damage or impact on the surface and the whole of the photovoltaic panel during the instantaneous sliding of the accumulated ice and snow during melting, thereby increasing the service life of the solar photovoltaic panel and reducing maintenance costs. Finally, the driving component drives the cleaning component to move, and the cleaning component can perform supplementary flushing, scraping, quick drying and dry wiping on the surface of the photovoltaic panel within the circle of the dividing plate 26, thereby ensuring the cleanliness, light transmittance and reflectivity of the photovoltaic panel surface.

[0049] The ice and snow processing equipment 100 according to the present invention drives the movement of the ice-breaking component, the ice-melting component and the cleaning component through the driving component, and the ice-melting component generates relative movement with the ice and snow, so as to gather the ice and snow accumulated on the surface of the photovoltaic panel partially into the receiving cavity and break up and dissolve the ice and snow, so as to preliminarily remove the ice and snow accumulated on the photovoltaic panel. The ice-breaking component can divide and enclose the ice and snow accumulated in the local area of ​​the photovoltaic panel surface and spray the ice and snow melting medium on the area, so as to avoid the damage or impact on the surface and the whole of the photovoltaic panel during the instantaneous sliding of the ice and snow when they melt, thereby improving the service life of the solar photovoltaic panel and reducing the maintenance cost. Finally, the driving component drives the cleaning component to move, and the cleaning component can perform supplementary flushing, scraping, quick drying and dry wiping on the surface of the photovoltaic panel within the encirclement of the dividing plate 26, thereby ensuring the cleanliness, light transmittance and reflectivity of the surface of the photovoltaic panel.

[0050] According to some embodiments of the present invention, the ice-breaking assembly includes: a center frame 21, a rail 22, a telescopic rod 23, a panel 201, a column 241 and a reset member 243, the center frame 21 is formed with a first mounting hole extending in the thickness direction; the rail 22 is slidably arranged on the center frame 21, and at least a portion of the rail 22 is in contact with the substrate 11; the telescopic rod 23 is arranged in the first mounting hole, and the telescopic rod 23 can be selectively extended or shortened; the panel 201 is arranged at one end of the telescopic rod 23 away from the rail 22, a second mounting hole extending in the thickness direction is formed on the panel 201, a frame 242 is further arranged on the side of the panel 201 close to the substrate 11, the column 241 is received in the second mounting hole and is located inside the frame 242, and the reset member 243 is sleeved on at least a portion of the periphery of the column 241.

[0051] Under the control of the center frame 21, the ice-breaking assembly as a whole performs reciprocating motion in the rail 22 until the ice-breaking assembly moves to the middle area of ​​the substrate 11. During this process, the panel 201, under the control of the telescopic rod 23, synchronously drives the column 241 to move away from the substrate 11. The ice-breaking assembly is controlled by the column 241 until the ice-breaking assembly conflicts with the ice layer on the surface of the photovoltaic panel and maintains a certain interaction force. Since a reset member 243 is sleeved on the outer periphery of the column 241, the reset member 243 can be constructed as a spring. The spring uses its own elastic reverse force to ensure that the column 241, under the dual action of the spring reverse force and the guidance of the frame 242 and the panel 201, ensures the mutual conflicting force between the ice-breaking assembly and the ice layer on the surface of the photovoltaic panel (dividing the ice and snow accumulation area).

[0052] In addition, the columns 241 are configured to be multiple and spaced apart from each other, the second mounting holes are configured to be multiple and one-to-one corresponding to the columns 241 , and the reset members 243 are configured to be multiple and one-to-one corresponding to the columns 241 .

[0053] According to some embodiments of the present invention, the ice-breaking assembly further includes: a corner plate 24, a connecting bracket 25 and a dividing plate 26, the corner plate 24 being arranged at one end of the column 241 away from the center frame 21; the connecting bracket 25 being arranged on one side of the corner plate 24 in the width direction and penetrating the corner plate 24 in the thickness direction; the dividing plate 26 being arranged on one end of the connecting bracket 25 away from the panel 201, the dividing plate 26 being constructed in two, the two dividing plates 26 being spaced apart from each other and arranged opposite to each other, the space between the two dividing plates 26 being the dividing and enclosing range of the dividing plates 26, the two dividing plates 26 being suitable for moving under the drive of the corner plate 24 and dividing and enclosing ice and snow accumulated in a local area on the surface of the photovoltaic panel.

[0054] According to some embodiments of the present invention, the ice-breaking assembly further includes: a spray chamber 27 and a nozzle 28. The spray chamber 27 is disposed on the end of the connecting bracket 25 away from the panel 201 and between the two dividing plates 26. A receiving cavity suitable for receiving an ice-melting medium is formed in the spray chamber 27. The nozzle 28 is connected to the receiving cavity, and the nozzle 28 is suitable for spraying the ice-melting medium onto the area divided and enclosed by the dividing plate 26.

[0055] In some specific embodiments, the ice-breaking assembly is provided with a spray chamber 27 and a nozzle 28, and a liquid storage cylinder 295 is provided on the side of the middle frame 21 close to the base plate. The spray chamber 27 is connected to the connecting bracket 25 and is located between the two dividing plates 26. The spray chamber 27 is connected to the liquid storage cylinder 295 through a hose. A accommodating cavity is formed in the spray chamber 27. The liquid storage cylinder 295 can provide an ice-melting medium into the accommodating cavity. The accommodating cavity can accommodate the ice-melting medium. The ice-melting medium can be constructed as an ethanol liquid. The spray chamber 27 is also provided with a strip window open toward the outside of the accommodating cavity, and the spray chamber 27 is also provided with a nozzle 28 connected to the accommodating cavity.

[0056] After the partition plate 26 divides and encloses the ice and snow accumulated in the local area on the surface of the photovoltaic panel, the spray chamber 27 gradually guides the ethanol liquid in the accommodating chamber to the area of ​​the strip window 271 and the nozzle 28, and then sprays the ethanol liquid in the accommodating chamber evenly onto the surface of the ice and snow accumulated in the area enclosed by the partition plate 26 through the strip window 271 and the nozzle 28 (in this process, the positive distribution layout between the strip window 271 and the partition plate 26 causes the ethanol solution to flow evenly toward the ice layer along the inner wall of the partition plate 26 under the action of gravity, and causes the contact surface between the partition plate 26 and the ice layer to gradually dissolve into a blank area, until the partition plate 26 contacts the surface of the photovoltaic panel, and then the enclosed area is completely separated from the external ice and snow area by the partition plate 26). The present application gradually and slowly dissolves the accumulated ice and snow by spraying ethanol liquid in the mist chamber, thereby avoiding damage or impact on the surface and the whole of the photovoltaic panel during the instantaneous sliding of the accumulated ice and snow during melting, thereby increasing the service life of the photovoltaic panel and reducing maintenance costs.

[0057] In addition, a heat source rod 272 is also provided on the spray chamber 27. When the spray chamber 27 sprays the ice-melting medium, the heat source rod 272 can emit heat radiation to accelerate the melting rate of the accumulated ice and snow in the area enclosed by the dividing plate 26, and implement a rapid drying treatment on the enclosed area after the accumulated ice and snow melt, thereby avoiding the occurrence of re-freezing after the ice layer on the surface of the photovoltaic panel melts.

[0058] According to some embodiments of the present invention, the ice-breaking assembly further includes: a support rod 29 and a cutting shovel 291. The support rod 29 is disposed on the side of the corner plate 24 away from the panel 201; the cutting shovel 291 is disposed on the side of the support rod 29 away from the corner plate 24. Since the cutting plate cannot completely isolate the leakage of ethanol liquid within its encircled range, the cutting shovel 291 can abut against the photovoltaic panel to isolate the further leakage of the ethanol liquid.

[0059] In addition, a tooth panel 292 is provided on the support rod 29, and the tooth panel 292 is located between the cutting shovel 291 and the dividing plate 26. A toothed area is formed at the edge of the tooth panel 292. The toothed area can reduce the friction between the tooth panel 292 and the ice layer, and accelerate the tooth panel 292 to break the ice layer. The cutting plate cannot completely isolate the leakage of ethanol in its encircled area. Therefore, the tooth panel 292 and the cutting plate are set as a buffer area for breaking ice and snow in adjacent areas.

[0060] In addition, an end face of the angle plate 24 away from the base plate 11 is clamped with an elastic rod 281 in an array, the number is at least one, and the cross-sectional shape of the elastic rod 281 is T-shaped, and a horizontal plate 282 is slidably clamped and installed at one end of the elastic rod 281 away from the base plate 11, and the number of the horizontal plate 282 is one, and a chiming frame 283 is detachably mounted on the end face of the side of the horizontal plate 282 away from the base plate 11 through bolts, and a cutting shovel 291 is clamped and installed at one end of the end face of the side of the horizontal section of the chiming frame 283 away from the base plate 11, and a toothed panel 292 is clamped and installed at the other end of the horizontal section of the chiming frame 283 away from the base plate 11, and in addition, a positive electrode sheet 286 is clamped and installed at one end of the elastic rod 281 away from the telescopic rod 23, and a negative electrode sheet 288 is clamped and installed in an array on the end face of the horizontal section of the chiming frame 283 close to the electric telescopic rod 23, and the positive electrode sheet 286 corresponds to the negative electrode sheet 288 one to one;

[0061] Early warning scheme for the upper limit of the interaction force between the cutting blade 291 or the tooth panel 292 and the ice layer: when the positive electrode 286 contacts the negative electrode 288, the contact signal is converted into an electrical signal and transmitted to the central processing system through the external PLC control system, and finally the early warning information is sent to the alarm device through the central processing system and an alarm is sounded.

[0062] According to some embodiments of the present invention, the ice-breaking assembly further includes: an air cabin 31, an air pump 32 and a wind plate 33, the air cabin 31 being arranged on the corner plate 24, and an air flow outlet being formed on the air cabin 31; the air pump 32 being arranged on a side of the corner plate 24 close to the base plate 11 and being connected to the air cabin 31, and the air pump 32 being suitable for delivering cold air to the air cabin 31; the wind plate 33 being arranged on the air cabin 31 and being located at the air flow outlet, and an extension section extending toward the cutting shovel 291 being formed on the wind plate 33, and the wind plate 33 being suitable for guiding the cold air flowing out of the air cabin 31 to the side of the cutting shovel 291 away from the cutting plate.

[0063] In some specific embodiments, an air cabin 31, an air pump 32 and a wind plate 33 are further provided in the ice breaking assembly. A side plate is provided on the side of the angle plate 24 away from the connecting bracket 25 in the width direction. A rotatable impeller 34 is provided on the side plate. An air cabin 31 is provided on the side of the side plate close to the cutting shovel 291. The air cabin 31 is connected to the angle plate 24. The air pump 32 is provided on the side of the angle plate 24 close to the base plate 11. The air cabin 31 is communicated with the air pump 32. An air flow outlet is formed on the air cabin 31. A wind plate 33 extending toward the cutting shovel 291 is provided at the air flow outlet. The air pump 32 can continuously transport cold air to the inside of the air cabin 31. The cold air The air flows out from the air flow outlet under the action of pressure, and is guided and directed by the wind plate 33 and the fan blades. The cold air flows evenly and fully along the extension direction of the wind plate 33 to the area on the side of the cutting shovel 291 away from the tooth panel 292, so as to ensure that the ice and snow accumulated in the area between the same side plate of the cutting shovel 291 is always kept within the freezing point range, thereby reducing the butterfly effect caused by the melting of ice and snow in the area on the side of the cutting shovel 291 close to the tooth panel 292, that is, avoiding the probability of ice and snow on the side of the cutting shovel 291 away from the tooth panel 292 melting and sliding down, ensuring the effective implementation of the zoned cleaning of ice and snow on the surface of the photovoltaic panel, and improving the overall integrity and service life of the photovoltaic panel.

[0065] In some specific embodiments, the ice and snow melting group is composed of a front bracket 41, a connecting rod 42, a bucket 43 and a discrete device 44. The front bracket 41 is connected to the end of the rail 22 away from the substrate 11, so as to realize the connection between the ice and snow melting assembly and the ice breaking assembly. The connecting rod 42 is arranged on the front bracket 41, and the bucket 43 is arranged at the end of the connecting rod 42 away from the front bracket 41. A receiving cavity for receiving accumulated ice and snow is formed in the bucket 43, and the discrete device 44 is received in the receiving cavity. The driving component controls the substrate 11 to drive the front bracket 41 to move until the end surface of the bucket 43 is aligned with the accumulated ice and snow. The vertical distance is at the specified height (and each subsequent time the height of the bucket 43 is adjusted, the vertical distance between the bucket 43 and the accumulated ice and snow is consistent), and the bucket 43 is always consistent with the operating speed of the drive component under the control of the front bracket 41. During this process, the relative movement between the bucket 43 in motion and the accumulated ice and snow in a stationary state gathers the accumulated ice and snow in the specified area into the receiving chamber. At the same time, the discrete device 44 rotates inside the receiving chamber and breaks up the accumulated ice and snow in the receiving chamber, preventing the accumulation of ice and snow inside the receiving chamber and ensuring the continuity of the operation of the bucket 43.

[0066] The present invention collects and removes the ice and snow accumulated on the surface of the photovoltaic panel through the bucket 43, that is, the relative movement between the bucket 43 in a relative motion state and the ice and snow accumulated in a relatively static state causes the ice and snow to gather inside the bucket 43. In this process, the ice and snow are broken up by the rotational cutting action of the discrete device 44, further assisting the transfer of the ice and snow to the internal area of ​​the bucket 43 and ensuring the continuity of the operation of the bucket 43. In addition, the accumulation of ice and snow in the receiving cavity is avoided, thereby improving the relative containment capacity of the bucket 43.

[0067] According to some embodiments of the present invention, the ice and snow melting assembly also includes: a heater 45, which is arranged in the receiving chamber. The heater 45 can generate heat to melt the accumulated ice and snow in the receiving chamber to prevent the accumulated ice and snow from accumulating in the receiving chamber, thereby further ensuring the continuity of the operation of the bucket 43.

[0068] According to some embodiments of the present invention, the cleaning assembly includes: a rear bracket 51, a water distribution pipe 52, a scraper 53, a heat dissipation pipe 55 and a wiping pad 54. The rear bracket 51 is arranged at the end of another rail 22 away from the substrate 11; the water distribution pipe 52 is arranged on the rear bracket 51 and is connected to the accommodating cavity; the scraper 53 is arranged at the end of the rear bracket 51 away from the middle frame 21; the heat dissipation pipe 55 and the wiping pad 54 are arranged at the end of the rear bracket 51 away from the middle frame 21 and are spaced apart from the scraper 53. The wiping pad 54 is suitable for absorbing moisture on the surface of the photovoltaic panel. The wiping pad 54 can be constructed as a sponge pad. The heat dissipation of the heat dissipation pipe 35 quickly dries the scraped area of ​​the scraper 53. Finally, the surface of the photovoltaic panel is wiped by the wiping pad 54, which fully ensures the cleanliness of the surface of the solar photovoltaic panel.

[0069] The water distribution pipe 52 and the receiving chamber are connected through an external hose. The external hose can transport the melted ice and snow in the bucket 43 to the water distribution pipe 52. The water distribution pipe 52 can spray the water produced by the melted ice and snow to the scraping area to rinse the scraping area, further improve the scraping effect of the scraper 53, realize the reuse of ice and snow resources, improve the cleanliness of the surface of the photovoltaic panel, and reduce the shortage and waste of water resources in special environments (such as deserts). After that, the surface of the photovoltaic panel is wiped with a wiping pad 54 to fully ensure the cleanliness of the surface of the photovoltaic panel.

[0070] According to some embodiments of the present invention, the driving assembly is fixed to the front frame 188 by a screw 187, and the driving assembly includes: a mounting frame 61, a connecting rod 62, a hub 63, a rotating shaft and a rotating belt 64, the connecting rod 62 is arranged on the mounting frame 61, and a selectively retractable connecting end is formed on the connecting rod 62, and the connecting end is connected to the side of the substrate 11 away from the photovoltaic panel; the rotating shaft is rotatably arranged on the mounting frame 61, and the rotating shaft is constructed into two spaced-apart parts; the hub 63 is sleeved on the outer periphery of the rotating shaft, and the hub 63 is constructed into two corresponding to the rotating shaft; the rotating belt 64 is sleeved on at least a portion of the outer periphery of the two hubs 63.

[0071] In some specific embodiments, the substrate 11, under the control of the connecting rod 62, drives the corresponding components of the ice-breaking assembly, the cleaning assembly and the ice-melting assembly to move away from the rotating belt 64 (so as to adapt to the thickness of ice and snow accumulated in different environments, that is, the thickness of ice and snow on the surface of the photovoltaic panel in the actual working environment is uncertain, so it is necessary to adjust the initial vertical height between the ice-breaking assembly, the cleaning assembly and the ice-melting assembly as a whole and the accumulated ice and snow through the connecting rod 62), until the vertical height between the end surface of one side of the bucket 43 close to the rotating belt 64 and the accumulated ice and snow is in a specified range; then, the rotating shaft is driven to rotate by an external drive motor, and the rotating shaft drives the wheel hub 63 to rotate (during actual operation, the power supply board 12 can provide power supply services to the external drive motor or other components that require electricity), and the wheel hub 63 drives the rotating belt 64 to rotate, and then The rotating belt 64 controls the movement of the mounting frame 61 carrying the connecting rod 62, and the base plate 11 is driven by the connecting rod 62 to synchronously drive the ice-breaking assembly, the cleaning assembly and the ice-melting assembly to move as a whole. Finally, the rotating belt 64 drives the ice-breaking assembly, the cleaning assembly and the ice-melting assembly to make reciprocating motion on the end face of the photovoltaic panel, so that the ice-breaking assembly, the cleaning assembly and the ice-melting assembly can contact and clear the ice and snow on the surface of the photovoltaic panel many times. According to the thickness of the accumulated ice and snow, the vertical height between the bucket 43 and the accumulated ice and snow can be adjusted many times by the connecting rod 62 according to the thickness of the accumulated ice and snow, so as to avoid the depth and volume of the single snow eating amount of the bucket 43, ensure the stable and smooth operation of the rotating belt 64, and reduce the occurrence of large-scale "avalanche" caused by the single snow shoveling amount of the bucket 43 exceeding the carrying range, thereby improving the integrity of the surface of the photovoltaic panel.

[0072] In summary, the present application uses symmetrically distributed dividing plates 26 to divide the local ice and snow accumulated on the surface of the solar photovoltaic panel during the movement. After that, the external ethanol liquid is transported to the nozzle 28 and the strip window 271 through the spray cabin 27 until the ethanol completely melts the ice and snow accumulated between the guide plates, thereby avoiding damage or impact to the surface and the whole of the solar photovoltaic panel during the instantaneous sliding of the ice and snow during melting, which helps to increase the service life of the solar photovoltaic panel and reduce maintenance costs; through the joint supplementary cleaning of the scraper 53, the heat dissipation pipe 55 and the wiping pad 54, the cleanliness, light transmittance and reflectivity of the solar photovoltaic panel surface are fully guaranteed, and the power conversion efficiency of the solar photovoltaic panel is improved.

[0073] Secondly, the bucket 43 is used to collect and remove the ice and snow accumulated near the ice layer on the surface of the solar photovoltaic panel. That is, the relative movement between the bucket 43 in a relatively moving state and the snow in a relatively static state causes the accumulated ice and snow to gather inside the bucket 43. In this process, the rotating cutting of the discrete device 44, on the one hand, further assists the transfer of the accumulated ice and snow to the inner area of ​​the bucket 43 to ensure the continuity of the operation of the bucket 43, and on the other hand, avoids the accumulation of ice and snow, improves the relative accommodation capacity of the bucket 43, and melts the ice and snow in the inner area of ​​the bucket 43 through the thermal radiation of the heater 45. Finally, the liquid snow is pumped to the water distribution pipe 52 through the external hose and the delivery pump, so as to realize the reuse of ice and snow resources, which is helpful to improve the cleanliness of the surface of the solar photovoltaic panel and reduce the shortage and waste of water resources in special environments (such as deserts).

[0074] The air pump 32 continuously delivers cold air to the interior of the air chamber 31. Under the action of pressure, the cold air is guided and directed by the wind plate 33 and the impeller 34, and flows evenly and fully to the area on the side of the cutting shovel 291 away from the tooth panel 292, thereby ensuring that the ice and snow accumulated in the area between the cutting shovel 291 and the air chamber 31 are always kept within the freezing point range, reducing the melting speed of the ice and snow accumulated in the area on the side of the tooth panel 292, and effectively preventing the butterfly effect, that is, avoiding the probability of ice and snow accumulated on the side of the cutting shovel 291 away from the tooth panel 292 melting and sliding down, ensuring the effective implementation of the zoned cleaning of ice and snow on the surface of the solar photovoltaic panels, and improving the overall integrity and service life of the solar photovoltaic panels.
