Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic component with a cleaning structure. Background Art

[0002] Photovoltaic modules are the core and most important part of a solar power generation system. They are usually installed outdoors to come into contact with sunlight, converting light energy into electrical energy for people to use.

[0003] A Chinese patent with publication number CN220022729U discloses a solar photovoltaic cleaning component, including a base, a support plate is arranged on the top of the base, a photovoltaic component is installed on the top of the support plate, and a first support group and a second support group are arranged on the top of the support plate, a guide rod is installed on the first support group, a screw rod is movably installed on the second support group, and one end of the screw rod is connected to the output shaft of the first motor, a movable plate is threadedly connected to the outer wall of the screw rod, the other end of the movable plate movably passes through the guide rod, and a rotating shaft is arranged on a side of the movable plate close to the photovoltaic component, a plurality of brushes are arranged on the surface of the rotating shaft, and a scraper is arranged on one side of the rotating shaft, both ends of the scraper are installed on the movable plate, and the bottom end of the scraper is close to the photovoltaic component.

[0004] The above technical solution can scrape away impurities such as dust or bird droppings on the photovoltaic panel by scraping. However, in actual use, when the scraper scrapes away sticky impurities, the impurities will be adsorbed on the scraper, causing the cleanliness of the scraper to decrease. When scraping the lower side, the impurities adsorbed on the scraper will be adsorbed on the photovoltaic panel again, causing secondary obstruction, resulting in less than neat cleaning.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a photovoltaic component with a cleaning structure.

After using it for a certain period of time, the driving motor 4 can be used to drive the driving screw 5 to rotate, and the driving block 6 can be pushed to move. When the driving block 6 moves, it drives the scraper 7 to scrape the bird droppings and dust on the upper side of the photovoltaic component 2. When the scraper 7 moves to the other side of the mounting frame 1, it will first contact with the tooth plate 8, and move to one side by squeezing the tooth plate 8, thereby driving the gear 9 to follow the rotation. During the rotation of the gear 9, the cleaning rod 10 and the rubber plate 11 follow the rotation to clean and remove the impurities that have been scraped by the scraper 7, so that the scraper 7 remains clean and tidy, and reduces the secondary pollution caused by impurities falling on the photovoltaic component 2 again during the resetting process after cleaning, resulting in poor cleaning.

[0032] By setting the tooth plate 8, the tooth plate 8 can be squeezed during the movement of the scraper 7 to drive the gear 9 to rotate, and then the gear 9 drives the cleaning rod 10 and the rubber plate 11 to follow the rotation. The scraper 7 is in contact with the rubber plate 11 to clean the impurities scraped out from one side of the scraper 7, so that the impurities are separated from the scraper 7, keeping the scraper 7 clean, and reducing the secondary pollution to the photovoltaic module 2 caused by the scraper 7 not being clean enough during subsequent cleaning, resulting in poor cleaning.
