Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic panel module cleaning, specifically an automatic cleaning device for photovoltaic power station modules. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy and is composed of special materials such as crystalline silicon panels and electronic components such as inverters. It is connected to the power grid and transmits electricity to the grid. Since PV power station modules are exposed, if they are not cleaned for a long time, surface deposits will cause hot spot effects, resulting in module degradation or other consequences, which will seriously affect the power generation of the PV power station. Therefore, PV modules must be cleaned regularly.

[0003] In related technologies, please refer to Chinese Patent No. CN221633695U, which specifically discloses a photovoltaic panel module cleaning device. When using this photovoltaic panel module cleaning device, to clean dust from the surface of the photovoltaic panel, a motor drives a transmission shaft, a first bevel gear, a screw, and a second bevel gear to rotate. This causes the screw to move the cleaning frame, allowing the cleaning brush to automatically clean the dust from the photovoltaic panel surface. The cleaned dust passes through an inclined structure at the bottom of the guide box and is then introduced into a collection box through the discharge port for collection. By inserting a pin into the guide box and the slide groove, the collection box can be positioned directly below the discharge port for dust collection. The collection box is also easy to disassemble; the positions of the limiting plate and the cleaning brush can be automatically adjusted through the cooperation of a baffle and a spring. When the cleaning brush wears down after prolonged use, it automatically conforms to the surface of the photovoltaic panel, resulting in better dust cleaning and reducing the need for frequent replacements, thus lowering costs.

[0004] The applicant found shortcomings in the use of the aforementioned photovoltaic panel cleaning device: although it can clean the surface of the photovoltaic panel, the cleaning effect of cleaning the photovoltaic panel surface with a single cleaning brush is not ideal, and the dust and other debris adhering to the photovoltaic panel surface are difficult to remove with the cleaning brush due to long-term adhesion to the photovoltaic panel.

[0005] In view of this, this technical solution proposes an automatic cleaning device for photovoltaic power station modules, which can better solve the problems mentioned above. Utility Model Content
