Technical Field

[0001] The utility model relates to the field of photovoltaic panel cleaning robots, in particular to a novel centralized photovoltaic power station cleaning robot. Background Art

[0002] Driven by policies, my country's photovoltaic industry has shown a rapid development trend in recent years. However, since 2019, the pace of upgrading silicon wafer size has continued to accelerate, and a variety of silicon wafers have appeared on the market, such as 156 mm, 158 mm, 166 mm, 182 mm, 185 mm and 210 mm. This multi-specification silicon wafer situation has brought many challenges to the selection and installation of photovoltaic power station components.

[0003] As an important part of green energy, the operation efficiency and stability of photovoltaic power stations are crucial. However, domestic photovoltaic power stations are currently facing the problem of diversified component specifications. In order to reduce costs or meet specific installation requirements, some photovoltaic power stations may choose to use components of different specifications. Although this non-standard component configuration has improved the flexibility of photovoltaic power stations to a certain extent, it also brings many disadvantages. Components of various specifications make it difficult to clean the components of photovoltaic power stations. The surface cleaning of photovoltaic components has a direct impact on their power generation efficiency. Since components of different specifications have different sizes, cleaning staff need to clean components of different sizes, which undoubtedly increases the complexity and difficulty of cleaning work. At the same time, components of different specifications may also cause compatibility issues of cleaning equipment, further increasing the cost of cleaning work.

[0004] At present, traditional photovoltaic module cleaning methods in China include manual cleaning, high-pressure water gun cleaning, etc. Traditional photovoltaic cleaning methods have low cleaning efficiency, waste a lot of water resources, and have high cleaning costs; non-standard photovoltaic power stations have various specifications of photovoltaic modules, and traditional hanging-type photovoltaic module cleaning robots cannot adapt to the cleaning needs of photovoltaic panels of different specifications, which brings great challenges to traditional hanging-type photovoltaic module cleaning robots.

[0039] Working principle:

[0040] When cleaning the surface of the photovoltaic modules distributed in the roof array, the staff first hangs the entire photovoltaic module cleaning robot on the surface of the photovoltaic module through the hanging roller 8, so that the cleaning brush wheel 26 can contact the surface of the photovoltaic module. The staff can adjust the cleaning range of the cleaning robot according to the width of the photovoltaic module, that is, adjust the operation of the electric push rod 6. The electric push rod 6 can change the position state of the two groups of first connecting plates 17 and second connecting plates 18 by adjusting between the two first telescopic rods 4 and the second telescopic rod 5, and adjust the expansion degree of the first connecting plates 17 and the second connecting plates 18 according to the specifications of the photovoltaic module;

[0041] After the adjustment is completed, cleaning operations can be carried out. The first drive motor 12 drives one of the transmission shafts 9 to rotate. With the assembly of two sets of latch rods 13, the two walking tracks 11 can be driven synchronously in the same direction, allowing the cleaning robot to move laterally on the surface of the photovoltaic panel. At the same time, during the process, the second drive motor 27 can drive several cleaning brush wheels 26 to rotate through the first positioning rod 19, the second positioning rod 20, and the rotating shaft 21, so as to effectively clean the dust and impurities on the surface of the photovoltaic panel.

[0042] In this solution, a spray mechanism and a blast mechanism can be further installed on the fixed surface of the electric push rod 6. The spray mechanism can automatically spray cleaning liquid on the surface of the photovoltaic module in a manner similar to a syringe needle during the operation of the cleaning robot, and cooperate with the cleaning brush wheel 26 to further improve the cleaning effect.

[0043] If a blower mechanism is used, that is, an electric blower is used to blow air toward the surface of the photovoltaic module, loose dust adhering to the surface of the photovoltaic module can be initially removed, and then the cleaning brush wheel 26 performs secondary cleaning to form multi-stage cleaning to achieve better cleaning effect.
