TECHNICAL FIELD
[0001] The present application relates to the technical field of cleaning, in particular to a device for treating accumulated ice and snow on a solar photovoltaic panel. BACKGROUND
[0002] In the related art, water vapor in the air condenses into snowflakes under certain conditions and naturally falls onto the surface of a 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 freezing, the snow will gradually begin to freeze and form accumulated ice and snow. As time passes and the temperature continues to drop, the ice layer will continue to thicken.
[0003] When the temperature rises, the accumulated ice and snow gradually melts, and the friction between the accumulated ice and snow and the photovoltaic panel decreases. Under the action of gravity, the accumulated ice and snow in the frozen state slides down in a local or overall distribution. In this process, the aforementioned condensation nuclei rub against the solar photovoltaic panel, and there is a scratching damage phenomenon on the surface of the solar photovoltaic panel. Even without condensation nuclei, the irregular shape and edges of the ice block also exist in the sliding process, causing a scratching phenomenon on the surface of the solar panel. That is, when a large volume of ice block slides, it leaves scratches on the surface of the solar panel under the dual action of gravity and friction, or even collides with the solar photovoltaic panel upon sliding, causing cracks and damage to the glass on the surface of the solar photovoltaic panel.
[0004] In addition, the accumulation of snow in the process of freezing and melting will cause a sharp change in the temperature of the surface of the solar panel, which in turn will cause thermal expansion and contraction of the solar photovoltaic panel material, internal stress changes or local overheating, damage to the solar photovoltaic panel cells and packaging materials, and reduction in the service life and performance of the solar panel.

During this process, the relative movement between the moving bucket 43 and the accumulated ice and snow in the static state collects the accumulated ice and snow in the specified area into the receiving cavity. At the same time, the disperser 44 rotates in the receiving cavity and scatters the accumulated ice and snow in the receiving cavity, preventing the accumulation of ice and snow in the receiving cavity and ensuring the continuity of the operation of the bucket 43.
[0066] The present application collects and removes the ice and snow on the surface of the photovoltaic panel through the bucket 43, that is, through the relative movement between the bucket 43 in the relative movement state and the accumulated ice and snow in the relative static state, to promote the accumulation of ice and snow into the bucket 43. In this process, the rotation and cutting of the disperser 44 scatter the accumulated ice and snow, further assisting the transfer of the accumulated ice and snow to the internal area of the bucket 43, and ensuring the continuity of the operation of the bucket 43. In addition, it also avoids the accumulation of ice and snow in the receiving cavity, improves the relative accommodation of the bucket 43, and improves the relative accommodation of the bucket 43.
[0067] According to some embodiments of the present application, the ice and snow melting assembly further comprises a heater 45 arranged in the receiving cavity. The heater 45 can generate heat to melt the accumulated ice and snow in the receiving cavity, preventing the accumulation of ice and snow in the receiving cavity, thereby further ensuring the continuity of the operation of the bucket 43.
[0068] According to some embodiments of the present application, the cleaning assembly comprises a rear support 51, a water distribution pipe 52, a scraper 53, a heat dissipation pipe 55 and a wiping pad 54. The rear support 51 is arranged at the end of the other rail 22 away from the base plate 11. The water distribution pipe 52 is arranged on the rear support 51 and communicates with the receiving cavity. The scraper 53 is arranged at the end of the rear support 51 away from the mid support 21. The heat dissipation pipe 55 and the wiping pad 54 are arranged at the end of the rear support 51 away from the mid support 21 and are arranged in a spaced manner with the scraper 53. The wiping pad 54 is adapted to absorb the moisture on the surface of the photovoltaic panel. The wiping pad 54 can be configured as a sponge pad. The heat dissipation of the heat dissipation pipe 35 implements rapid drying on the scraped area of the scraper 53. Finally, the surface of the photovoltaic panel is wiped by the wiping pad 54, fully ensuring the cleanliness of the surface of the solar photovoltaic panel.
[0069] The water distribution pipe 52 and the receiving cavity are connected by 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 generated by the melting ice and snow onto the scraping area to rinse and process the scraping area, further improving the scraping effect of the scraper 53, realizing the reuse of ice and snow resources, improving the cleanliness of the photovoltaic panel surface, and reducing the scarcity and waste of water resources in special environments (such as deserts). Afterwards, the photovoltaic panel surface is wiped with a wiping pad 54 to fully ensure the cleanliness of the photovoltaic panel surface.
[0070] According to some embodiments of the present invention, the drive assembly is fixed to the front frame 188 of the vehicle by a screw 187. The drive 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 disposed on the mounting frame 61 and has a selectively telescopic connecting end formed on the connecting rod 62. The connecting end is connected to the side of the substrate 11 opposite to the photovoltaic panel. The rotating shaft is rotatably disposed on the mounting frame 61, and two rotating shafts are configured to be spaced apart. The hub 63 is sleeved on the outer periphery of the rotating shaft, and two hubs 63 are configured to be correspondingly disposed 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, cleaning assembly, and snow-melting assembly to move away from the rotating belt 64 (to adapt to the thickness of ice and snow accumulation in different environments; that is, the thickness of ice and snow accumulation on the surface of the photovoltaic panel is variable in actual operating environments, so the initial vertical height between the ice-breaking assembly, cleaning assembly, and snow-melting assembly and the accumulated ice and snow needs to be adjusted by the connecting rod 62) until the vertical height between the end face of the bucket 43 near the rotating belt 64 and the accumulated ice and snow is within a specified range; then, the external drive motor drives the rotating shaft to rotate, and the rotating shaft drives the hub 63 to rotate (during actual operation, the power supply board 12 can provide power to the external drive motor or other components that require power), and the hub 63 drives the rotating belt 64 to rotate, after which... The rotating belt 64 controls the mounting frame 61 to carry the connecting rod 62, and drives the substrate 11 to move the ice-breaking component, cleaning component, and snow-melting component together. Finally, the rotating belt 64 drives the ice-breaking component, cleaning component, and snow-melting component to reciprocate on the end face of the photovoltaic panel, so that the ice-breaking component, cleaning component, and snow-melting component can repeatedly contact and remove ice and snow from the surface of the photovoltaic panel. 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 multiple times by the connecting rod 62 to avoid the depth and volume of the snow picked up by the bucket 43 in a single operation. This ensures that the rotating belt 64 runs stably and smoothly, while reducing the occurrence of large-area "avalanche" phenomenon caused by the bucket 43 picking up more snow than its bearing capacity in a single operation, thereby improving the integrity of the photovoltaic panel surface.
[0072] In summary, this application uses symmetrically distributed dividing plates 26 to divide the localized ice and snow accumulation on the surface of the solar photovoltaic panel during travel. Subsequently, external ethanol liquid is delivered to the nozzle 28 and the strip window 271 through the spray chamber 27 until the ethanol completely melts the ice and snow accumulation between the guide plates. This avoids damage or impact to the surface and overall structure of the solar photovoltaic panel during the instantaneous sliding of the melting ice and snow, which helps to improve the service life of the solar photovoltaic panel and reduce maintenance costs. The combined supplementary cleaning by the scraper 53, heat dissipation pipe 55 and wiping pad 54 fully ensures the cleanliness, light transmittance and reflectivity of the solar photovoltaic panel surface, thereby improving the power conversion efficiency of the solar photovoltaic panel.
[0073] Secondly, the bucket 43 collects and removes the ice and snow near the surface of the solar photovoltaic panel. This is achieved through the relative movement between the bucket 43 in motion and the snow in a relatively stationary state, causing the ice and snow to gather towards the inside of the bucket 43. During this process, the rotating discriminator 44 further assists in the transfer of ice and snow to the inner area of the bucket 43, ensuring the continuity of the bucket 43's operation. On the other hand, it prevents the accumulation of ice and snow, improving the relative capacity of the bucket 43. The heat radiation from the heater 45 melts the ice and snow in the inner area of the bucket 43. Finally, the liquid snow is pumped to the water distribution pipe 52 through an external hose and a delivery pump, thereby realizing the reuse of ice and snow resources. This helps improve the cleanliness of the solar photovoltaic panel surface and reduces the scarcity and waste of water resources in special environments (such as deserts).
[0074] The air pump 32 continuously supplies cold air into the air chamber 31. Under pressure, the cold air is guided and directed by the combined flow of the air deflector 33 and the impeller 34, flowing evenly and sufficiently to the area of the cutting shovel 291 away from the toothed panel 292. This ensures that the ice and snow accumulation in the area between the cutting shovel 291 and the air chamber 31 is always kept within the freezing point range, reducing the melting rate of the ice and snow accumulation on the toothed panel 292 side and effectively preventing the butterfly effect. This avoids the probability of the ice and snow accumulation on the side of the cutting shovel 291 away from the toothed panel 292 melting and sliding down, ensuring the effective implementation of 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.
