Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically to a photovoltaic panel surface cleaning device. Background Technology

[0002] Photovoltaic panels are a core component of solar power systems. Their main function is to convert sunlight into direct current (DC) electricity to power electrical equipment or, through an inverter, into alternating current (AC). Maintaining the cleanliness of the photovoltaic panel surface is crucial for its efficient solar energy conversion. Cleaning the photovoltaic panel surface helps maximize its ability to absorb solar energy and improves the efficiency of the solar cells.

[0003] When cleaning the surface of photovoltaic panels, a soft, non-abrasive cloth or sponge dipped in warm water is usually used. This manual cleaning method is labor-intensive. To improve the cleaning efficiency of photovoltaic panel surfaces, many automatic photovoltaic panel cleaning devices have emerged. Some of these automatic cleaning devices are installed on one side of the photovoltaic panel mounting frame and clean the photovoltaic panels through mechanical transmission and cleaning strips. Others are mobile automatic cleaning devices that are manually pushed and clean the photovoltaic panels through mechanical transmission and cleaning strips. Both of these cleaning devices have complex structures and high manufacturing costs, and are suitable for environments with a large number of photovoltaic panels.

[0004] However, using the above-mentioned automatic cleaning structure in environments with a small number of photovoltaic panels can easily lead to a waste of resources. In reality, environments with a small number of photovoltaic panels still mostly rely on manual cleaning, but existing manual cleaning tools have a small cleaning area and low cleaning efficiency.

[0005] To address the aforementioned technical problems, this application proposes a manual cleaning device for photovoltaic panel surfaces. Utility Model Content

[0024] As attached Figure 1 and attached Figure 2 As shown, a photovoltaic panel surface cleaning device includes a mounting frame 1, which is a horizontally placed U-shaped structure with a handle 7 mounted on the upper side. A first sponge board 2 is mounted on the lower side of the mounting frame 1. Extension frames 4 are rotatably mounted inside both ends of the mounting frame 1. A second sponge board 6 is mounted on the lower side of the two sets of extension frames 4. A folding rod 3 is rotatably connected to one end of the extension frame 4, and the other end of the folding rod 3 is rotatably mounted inside the mounting frame 1. When the extension frame 4 is unfolded, the mounting frame 1 supports one side of the folding rod 3. A limiting plate is installed on one side of the extension frame 4 to prevent the extension frame 4 from bending excessively during cleaning. The two sets of extension frames 4 are rotated and stored inside the mounting frame 1, so that the movement trajectory of the second sponge board 6 coincides with that of the first sponge board 2, which can reduce the cleaning area of ​​the cleaning device.

[0025] The two sets of folding rods 3 have different lengths. When the extension frame 4 is rotated and stored inside the mounting frame 1, the two sets of extension frames 4 are arranged side by side inside the mounting frame 1, which makes it easy to store the cleaning device.

[0026] As attached Figure 1 As shown, a protruding strip 5 connects the extension frame 4 and the second sponge board 6. The second sponge board 6 is installed on the outside of the mounting frame 1 through the protruding strip 5. The first sponge board 2 and the second sponge board 6 are on the same plane. When the extension frame 4 is unfolded, the ends of the first sponge board 2 and the second sponge board 6 are in contact. When cleaning the surface of the photovoltaic panel, there will be no gap between the first sponge board 2 and the second sponge board 6, and no cleaning omissions will occur.

[0027] To facilitate the installation and removal of towels on the outer sides of the first sponge board 2 and the second sponge board 6, see attached... Figure 3 and attached Figure 4As shown, the inner sides of the first sponge board 2 and the second sponge board 6 are respectively provided with multiple sets of mounting components. The mounting components include block-shaped hook and loop fasteners 9 and springs 10. The inner sides of the first sponge board 2 and the second sponge board 6 are respectively provided with multiple sets of mounting grooves 8. The bottom of the multiple sets of mounting grooves 8 extends into the interior of the protrusion 5 and the interior of the side wall of the mounting frame 1. The block-shaped hook and loop fasteners 9 slide out at the groove opening of the mounting groove 8. One end of the spring 10 is installed at the bottom of the mounting groove 8, and the other end is installed with a connecting block 11. The block-shaped hook and loop fasteners 9 are installed on the other side of the connecting block 11. The cleaning towel is stuck to the outside of the multiple sets of block-shaped hook and loop fasteners 9 for positioning. The two side walls of the extension frame 4 and the one side wall of the mounting frame 1 are respectively installed with strip-shaped hook and loop fasteners 12, and the edge of the cleaning towel is stuck to the outside of the strip-shaped hook and loop fasteners 12. The cleaning towel is pasted to the outside of the first sponge board 2 and the second sponge board 6. The cleaning towel can be removed from the outside of the first sponge board 2 and the second sponge board 6 by tearing.

[0028] The specific usage method is as follows:

[0029] The cleaning towel is attached to the outside of the first sponge board 2 and the second sponge board 6. Depending on the size of the photovoltaic panel, one or two sets of extension racks 4 can be rotated out from the mounting frame 1 to make the first sponge board 2 and the second sponge board 6 in a straight line. Adjust the cleaning area of ​​the cleaning device. During cleaning, spray some mist-like cleaning liquid on the dirty areas of the photovoltaic panel surface. Hold the handle 7 and attach the cleaning towel to the photovoltaic panel surface. Gently press down on the mounting frame 1, and the block-shaped Velcro 9 moves into the mounting groove 8, so that the cleaning towel contacts the first sponge board 2 and the second sponge board 6 and moves laterally to clean the dirty areas of the photovoltaic panel surface. Some of the cleaning water enters the interior of the first sponge board 2 and the second sponge board 6 through the cleaning towel for collection, which can reduce the amount of cleaning water remaining on the photovoltaic panel surface.
