Description

Technical Field

[0001] The invention relates to the technical field of snow removal for photovoltaic panels, and in particular to an automatic snow removal device for photovoltaic panels. Background Art

[0002] The main components of a photovoltaic power station are photovoltaic conversion panels. The light receiving rate of the panels directly affects the power generation efficiency of the system. When snow accumulates on the surface of the panels, it blocks the photoelectric conversion module, directly affecting the light receiving rate of the panels, significantly reducing the power generation. In order to improve the power generation efficiency, the snow on the surface of the panels must be cleared in time.

[0003] At present, the traditional way to remove snow from photovoltaic panels is to manually scrape the snow off the surface of the photovoltaic panels with a snow scraper. This snow removal method is too inefficient and has a high removal cost. In addition, due to the large area of ​​the photovoltaic panel array, a large amount of snow will accumulate on one side of the photovoltaic panel when scraping the snow from the photovoltaic panel, making it impossible to scrape the snow off the photovoltaic panel. In addition, manual snow removal is often done directly on the photovoltaic panel with a snow scraper. However, the position where the snow contacts the photovoltaic panel is prone to ice formation due to the low temperature. Rough manual cleaning with a snow scraper not only fails to completely remove the ice layer, but also easily damages the photovoltaic panel.

[0004] In order to solve the above problems, a Chinese patent with publication (announcement) number CN113714238B discloses a photovoltaic panel cleaning device that is convenient for automatic snow removal, wherein two symmetrical bases are fixedly connected to one side of the top of a placement plate, a same mounting frame is rotatably connected between the two bases, a photovoltaic panel is arranged in the mounting frame, a scraper and a sliding plate are slidably connected to both sides of a sliding arm at the top of the mounting frame, a snow removal component for preliminary snow removal from the surface of the photovoltaic panel is arranged in the placement plate, a snow melting component for preliminary melting of the ice layer on the surface of the photovoltaic panel is arranged in the sliding arm, a deicing component for clearing the ice layer on the surface of the photovoltaic panel is arranged on one side of the sliding plate, and a driving component for controlling the scraper and the sliding plate to slide toward each other is arranged on the top of the sliding arm.

[0005] The above-mentioned photovoltaic panel cleaning device that is easy to automatically remove snow solves the problems of low snow removal efficiency in existing photovoltaic panel snow removal methods, the inability to easily scrape snow off the photovoltaic panels, the inability to effectively remove ice on the photovoltaic panels and the easy damage to the photovoltaic panels.

[0039] Specifically, in this embodiment, the scaffold 101 is grounded through a grounding wire, and the grounding wire can quickly conduct leakage current or lightning current that may be generated on the scaffold 101 to the earth, thereby avoiding the occurrence of electrical accidents. This is crucial to protecting the safety of personnel and equipment. The grounding wire can also reduce the electromagnetic interference of electrical equipment and ensure the normal and stable operation of the equipment. In the automatic snow removal device for photovoltaic panels, this helps to ensure the communication stability and working reliability of the remote control device 3 and the automatic snow removal mechanism 2. In thunder and lightning weather, the grounding wire can lead the lightning charge generated on the scaffold 101 to the ground, thereby reducing the possibility of lightning damage. This is of great significance for protecting photovoltaic panels and other electrical equipment from lightning damage. Through reasonable grounding wire arrangement and connection, the grounding resistance can be reduced and the lightning protection effect can be improved. Ensuring that the grounding resistance value meets the specified standards is the key to achieving the expected lightning protection effect. The grounding wire can form an equipotential body between the scaffold 101 and the earth, thereby avoiding electrical problems caused by potential differences. This helps to enhance the stability of the entire photovoltaic panel automatic snow removal device, and the grounding wire can also effectively reduce the accumulation of static electricity on the scaffolding 101, preventing static electricity discharge from causing damage to equipment and personnel.
