DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] A solar panel with self-cleaning function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a mounting base plate 1, an outer frame 2 and a solar panel 3, the middle part of the mounting base plate 1 is connected to the outer frame 2, and the solar panel 3 for photovoltaic power generation is installed in the outer frame 2, and also includes a cleaning mechanism 4, the cleaning mechanism 4 includes a mounting frame 41, a roller 42, a first connecting frame 43, a mounting frame 44, a driving component 45, a rack 46, a gear 47, a roller brush 48 and a scraper 49, the edge of the mounting base plate 1 is connected to the mounting frame 41, the front and rear parts of the mounting frame 41 are both slidably connected to the roller 42 for auxiliary movement, the non-adjacent side of the roller 42 is rotatably connected to the first connecting frame 43, the upper part of the first connecting frame 43 is connected to the mounting frame 44, the front part of the mounting frame 41 is connected to the driving component 45 for driving the first connecting frame 43 to move, and the driving component 45 includes a connecting A connecting frame, a driving motor and a screw rod, a connecting frame is connected to the right side of the front of the mounting frame 41, a driving motor is connected to the connecting frame, the output shaft of the driving motor passes through the right side of the mounting frame 41 and is connected to a screw rod, the screw rod is rotatably connected to the front of the mounting frame 41, the screw rod is threadedly connected to the front first connecting frame 43, a gear 47 is rotatably connected to the front inner part of the mounting frame 44, a roller brush 48 for cleaning the surface of the solar panel 3 is rotatably connected to the rear side of the middle part of the gear 47, the roller brush 48 is rotatably connected to the mounting frame 41, an arc-shaped elastic scraper 49 for scraping off water stains for cleaning is connected to the right side of the mounting frame 44, the lower part of the scraper 49 is conical, which is convenient for scraping off water stains on the solar panel 3, a rack 46 is connected to the upper side of the front of the mounting base plate 1, and the gear 47 is meshed with the rack 46.

[0022] When using the solar panel 3 for photovoltaic power generation, the device can be used. It should be noted that the mounting base plate 1 is first installed to fix the solar panel 3, so that the solar panel 3 can be used for photovoltaic power generation. A water spraying device is externally connected around the solar panel 3. After the solar panel 3 is used for a long time, dust and other debris and foreign matter often fall on the surface of the solar panel 3. The driving component 45 regularly controls the first connecting frame 43 to move to the left. At this time, the rollers 42 are all rotated by force so that the first connecting frame 43 drives the roller brush 48 to move to the left through the mounting frame 44. The surface of the solar panel 3 is cleaned, and at the same time, an external water spraying device sprays water on the surface of the solar panel 3, so that the scraper 49 scrapes the remaining water stains on the surface of the solar panel 3 to the left, and then the driving component 45 is used to drive the first connecting frame 43 to move to the right and reset. At this time, the rollers 42 all rotate in the opposite direction, so that the first connecting frame 43 drives the roller brush 48 to slide to the left and reset through the mounting frame 44. In summary, the cooperation between the roller brush 48 and the scraper 49 can clean the surface of the solar panel 3, thereby improving the cleaning quality of the solar panel 3.

[0023] like Figure 1 and Figure 5 As shown, it also includes a collecting mechanism 5, which includes a second connecting frame 51, a collecting frame 52, a filter 53 and a valve 54. Three second connecting frames 51 are connected to the left side of the lower part of the installation frame 41, and the upper parts of the second connecting frames 51 are connected to ribs. A collecting frame 52 for collecting and cleaning sewage is connected between the right sides of the lower parts of the second connecting frames 51. A filter 53 for filtering sewage is slidably connected in the upper part of the collecting frame 52. A valve 54 for switching on and off the transportation of sewage is connected to the lower part of the front part of the collecting frame 52, and a booster block is connected to the left part of the valve 54.

[0024] It should be noted that when the roller brush 48 and the scraper 49 are used to clean the surface of the solar panel 3, the water sprayed by the external water spraying equipment flows along the inclined surface on which the solar panel 3 is installed to the collection frame 52. At this time, the filter 53 filters the cleaned sewage, so that the filtered sewage is stored in the collection frame 52. When the sewage needs to be reused, the valve 54 can be opened to transport the sewage to other places where it is needed. When the filter 53 needs to be replaced, the filter 53 is slid upward out of the collection frame 52, and then the cleaned filter 53 or the new filter 53 is slid and placed in the upper part of the collection frame 52. In summary, the collection frame 52 and the filter 53 cooperate to collect and store the sewage, and then recycle the sewage, thereby improving resource utilization.
