DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] See also Figure 1-13 The photovoltaic system provided in the embodiment of the present application includes a photovoltaic panel body 101 and a top plate 102, wherein the top plate 102 is disposed on the photovoltaic panel body 101. A foreign matter cleaning component for cleaning foreign matter on the upper end of the photovoltaic panel body 101 is disposed on the top plate 102, and a foreign matter detection component for detecting foreign matter on the upper end of the photovoltaic panel body 101 is disposed on the foreign matter cleaning component.

[0021] During the normal use of the photovoltaic panel body 101, the photovoltaic panel body 101 is in an outdoor environment, and the photovoltaic panel body 101 is exposed to sunlight to generate electricity. But at the same time, a large amount of dust and dirt will adhere to the surface of the photovoltaic panel body 101 outdoors, and these attached dust and dirt will affect the power generation efficiency of the photovoltaic panel body 101. Therefore, the surface of the photovoltaic panel body 101 can be cleaned regularly by a foreign body cleaning component. In addition, birds will excrete feces at the top of the photovoltaic panel body 101, and these feces are usually attached and accumulated in the upper end area of ​​the photovoltaic panel body 101. Therefore, the foreign body cleaning component set on the top plate 102 is used to clean this area specifically.

[0022] Among them, see Figures 2 to 4 The foreign matter cleaning component includes a medicine box 202, a circular plate 206, a scraper 207 and a first brush 208. The medicine box 202 is arranged directly above the circular plate 206. Four mutually staggered scrapers 207 and a first brush 208 are fixed to the bottom end of the circular plate 206. The scrapers 207 and the first brush 208 are in contact with the surface of the photovoltaic panel body 101.

[0023] When it is necessary to clean foreign objects attached to the surface of the photovoltaic panel main body 101, the cleaning liquid in the medicine box 202 is made to flow out from the inside of the first brush 208, and the circular plate 206 is driven to rotate at the same time. The circular plate 206 can drive the scraper 207 and the first brush 208 to rotate. The rotation of the scraper 207 and the first brush 208 cooperates with the flowing liquid to effectively clean the foreign objects attached to the surface of the photovoltaic panel main body 101, thereby achieving special cleaning of the upper end area of ​​the photovoltaic panel main body 101.

[0024] Please continue reading Figures 2 to 4 The foreign matter cleaning assembly also includes a first fixed plate 201 fixed to the top plate 102, a medicine box 202 fixed to the bottom of the first fixed plate 201, a fixed column 203 connected to the bottom of the medicine box 202, and a first connecting rod 204 rotatably connected to the bottom end of the fixed column 203. A second fixed plate 205 is fixed to the top of the circular plate 206, and the first connecting rod 204 is rotatably connected to the middle of the second fixed plate 205. A liquid inlet channel 210 is provided in the first connecting rod 204 and the circular plate 206, and a liquid outlet 209 connected to the liquid inlet channel 210 is provided on the first brush 208.

[0025] When it is necessary to clean foreign matter attached to the surface of the photovoltaic panel body 101, the cleaning liquid in the medicine box 202 enters the first brush 208 through the liquid inlet channel 210, flows out from the first brush 208 through the liquid outlet 209, and reacts with the foreign matter. Subsequently, the first connecting rod 204 is driven to rotate, the first connecting rod 204 drives the circular plate 206 to rotate, the circular plate 206 drives the four scrapers 207 and the first brush 208 to rotate, the scraper 207 scrapes off the foreign matter attached to the surface of the photovoltaic panel body 101, and the first brush 208 performs secondary cleaning on the foreign matter scraped off by the scraper 207. With the liquid flowing out of the medicine box 202, the foreign matter attached to the surface of the photovoltaic panel body 101 can be effectively cleaned, and the special cleaning of the upper end area of ​​the photovoltaic panel body 101 can be achieved, and the flatness of the surface of the photovoltaic panel body 101 can be maintained, which is conducive to the full use of light, ensuring the cleanliness of the surface of the photovoltaic panel body 101, reducing obstruction, and thus improving the power generation efficiency.

Since foreign matter accumulates on the surface of the photovoltaic panel main body 101, the surface of the photovoltaic panel main body 101 becomes uneven. When the cylinder 306 contacts the foreign matter attached to the surface of the photovoltaic panel main body 101, the cylinder 306 is pushed upward by the foreign matter, and the spring 303 drives the rectangular plate 304 and the pressure sensor 307 to move upward.
