Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, and in particular to a maintenance and cleaning device for photovoltaic power generation. Background Technology

[0002] As the global energy structure shifts towards clean energy, photovoltaic power generation, as one of the most mature and widely used renewable energy sources, continues to experience rapid growth in installed capacity. However, pollutants on the surface of photovoltaic panels (such as dust, bird droppings, fallen leaves, and salt spray) can form a shading layer, leading to a decrease in light flux. Currently, cleaning tools for photovoltaic panels are mainly divided into two categories: manual tools (such as rags and scrapers) and small mechanical handheld devices. However, existing cleaning tools typically use a single bolt for installation, which can easily cause vibrations that loosen or even detach the brush. Reinstallation is not only time-consuming, but also poses a risk of the brush rolling off and potentially injuring cleaning personnel. Utility Model Content

It is easier to push and pull the frame plate 7 back and forth. Water is supplied to the water pipe 8 by the water pump 3. The water outlet on the water pipe 8 sprays water onto the surface of the photovoltaic panel. When pushing and pulling the frame plate 7 back and forth, the brush 12 and water are used to clean the surface of the photovoltaic panel. When installing or replacing the brush 12, insert the insert block 11 on the brush 12 into the mounting groove 10, and then use the first bolt 14 to thread through the fixing frame 13 and screw in the insert block 11 to complete the installation of the brush 12.

[0018] Furthermore, a switch 5 is fixedly connected to the top of the cart 1, and a battery 6 is installed on the top of the cart 1.

[0023] Working principle: In use, hold the handle 20 and place the frame plate 7 on top of the photovoltaic panel. Move it using the wheels 9, making it easier to push and pull the frame plate 7 back and forth. Water is supplied to the water pipe 8 by the water pump 3, and the water outlet on the water pipe 8 sprays water onto the surface of the photovoltaic panel. When pushing and pulling the frame plate 7 back and forth, the brush 12, in conjunction with the water, cleans the surface of the photovoltaic panel. When installing or replacing the brush 12, insert the insert block 11 on the brush 12 into the mounting slot 10, then thread the first bolt 14 through the fixing frame 13 and screw it into the insert block 11 to complete the installation of the brush 12. Insert the buckle 17 on the baffle 16 into the fixing box 15 and lock it in place, so that one side of the baffle 16 fits against one end of the first bolt 14, thereby securing the first bolt. The bolt 14 is fixed in place to prevent detachment and ensures that the brush 12 is installed stably during use. When cleaning the photovoltaic panel, the handle 20 can be tilted and the second bolt 22 can be turned. The second bolt 22 is threaded to the connecting seat 18, which drives the sliding plate 23 to slide, so that the sliding plate 23 engages with the fixed plate 21, thereby fixing the support angle of the handle 20. When cleaning the photovoltaic panel on the ground, the handle 20 can be laid flat and the angle of the handle 20 can be adjusted according to the usage situation, making it more convenient for the operator to hold. When not in use, the handle 20 can be stood up at a 90-degree angle to the frame plate 7, and the frame plate 7 can be placed into the storage box 24. The handle 20 is then clipped into the C-shaped pipe clamp 25 for storage, saving space.
