Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module cleaning devices, and in particular relates to a solar photovoltaic power generation panel with self-cleaning function. Background Technology

[0002] Solar photovoltaic (PV) panels are devices that directly convert solar energy into electrical energy. They are mainly composed of photovoltaic cells, glass covers, encapsulation materials, and backsheets. Their core function is to generate direct current through the photoelectric effect. They are widely used in ground-mounted power stations, rooftop distributed power generation, and off-grid power supply systems. Because PV panels are exposed to the outdoor environment for a long time, their surfaces are prone to accumulating pollutants such as dust, gravel, bird droppings, and pollen, which leads to a decrease in power generation efficiency. Therefore, keeping the surface of PV panels clean is the key to maintaining high-efficiency power generation.

[0003] Existing self-cleaning devices still have some problems during use. For example, they often use rotating brushes to rub the surface of the photovoltaic panel. If there are impurities such as sand or hard particles, they can easily scratch the photovoltaic glass during the brushing process, causing permanent wear and affecting the light transmittance. To address these issues, we provide a solar photovoltaic panel with a self-cleaning function. Utility Model Content

[0004] The purpose of this invention is to provide a solar photovoltaic panel with a self-cleaning function. By cooperating with the moving mechanism and the cleaning mechanism, it solves the problem that existing self-cleaning devices often use rotating brushes to rub the surface of the photovoltaic panel. If there are impurities such as sand or hard particles, they can easily scratch the photovoltaic glass during the brushing process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a solar photovoltaic power generation panel with a self-cleaning function, comprising a photovoltaic panel, a movable frame fixedly connected to the outside of the photovoltaic panel, a moving mechanism provided on the top of the movable frame, the moving mechanism including a cleaning frame provided on the top of the photovoltaic panel, a drive motor fixedly connected inside the cleaning frame, a drive gear fixedly connected to the output end of the drive motor, and a toothed plate meshing with the drive gear, a cleaning mechanism provided inside the cleaning frame, the cleaning mechanism including a scraper fixedly connected to one side of the cleaning frame, a first water spraying assembly provided on the top of the scraper, a cleaning brush provided inside the cleaning frame, a second water spraying assembly provided inside the cleaning frame, and a scraper fixedly connected to the other side of the cleaning frame.

[0007] The present invention is further configured such that a fixed through groove is provided on both sides of the bottom of the movable frame, and the drive motor is fixedly connected inside the drive through groove.

[0008] The present invention is further configured such that support rods are fixedly connected to both sides of the movable frame, support blocks are slidably connected to the surface of the support rods, and the top of the support blocks is fixedly connected to the bottom of the movable frame.

[0009] The present invention is further configured such that there are two toothed plates, and the two toothed plates are respectively fixedly connected to both sides of the movable frame.

[0010] The present invention is further configured such that the first water spray assembly includes a water spray plate fixedly connected to the top of the scraper plate, a first water pipe fixedly connected inside the water spray plate, and a first nozzle communicating with the surface of the first water pipe.

[0011] The present invention is further configured such that drainage channels are provided on both sides of the movable frame, and the number of cleaning brushes is two, the two cleaning brushes being connected to the synchronous wheel via a servo motor.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves the movement of the cleaning frame by using the drive gear and toothed plate transmission of the moving mechanism, and the sliding structure of the support rod and support block to work together. When the drive motor drives the drive gear to rotate, it meshes with the toothed plate to push the cleaning frame to move smoothly. The cooperation between the support rod and the support block eliminates running deviation. This movement process ensures that the cleaning mechanism covers the surface of the photovoltaic panel, avoids cleaning dead corners, and reduces the potential damage to the photovoltaic panel caused by mechanical vibration, significantly improving the stability and reliability of the cleaning operation.

[0015] 2. This utility model achieves efficient cleaning through the multi-stage collaborative design of the cleaning mechanism. After the first water spray component pre-rinses, the scraper pushes away large particles of impurities, and the cleaning brush performs deep cleaning with the assistance of the second water spray. Finally, the scraper removes the wastewater. The staged treatment avoids scratching the surface with grit and reduces brushing friction through water spraying lubrication. This process effectively separates the impurity removal and fine cleaning steps, improving cleaning efficiency while protecting the surface of the photovoltaic panel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific Implementation Example 1. Please refer to [link / reference]. Figures 1-5This utility model relates to a self-cleaning solar photovoltaic panel, comprising a photovoltaic panel 1, a movable frame 2 fixedly connected to the outside of the photovoltaic panel 1, a moving mechanism 3 disposed on the top of the movable frame 2, and the moving mechanism 3 including a cleaning frame 301 disposed on the top of the photovoltaic panel 1, and a drive motor 302 fixedly connected inside the cleaning frame 301. The drive motor 302 is a device that converts electrical energy into mechanical energy, and its working principle is based on the law of electromagnetic induction and Lorentz force, which is existing technology. This solution will not be elaborated upon further, and those skilled in the art will clearly understand its operation. The working principle is as follows: a drive gear 303 is fixedly connected to the output end of the drive motor 302, and a toothed plate 304 meshes with the drive gear 303. A cleaning mechanism 4 is provided inside the cleaning frame 301. The cleaning mechanism 4 includes a scraper 401 fixedly connected to one side of the cleaning frame 301, a first water spraying assembly 402 set on the top of the scraper 401, a cleaning brush 403 set inside the cleaning frame 301, a second water spraying assembly 404 set inside the cleaning frame 301, and a squeegee 405 fixedly connected to the other side of the cleaning frame 301.

[0026] Specifically, through the setting of the moving mechanism 3, the drive motor 302 drives the drive gear 303 to mesh with the toothed plate 304, so that the cleaning frame 301 moves along the surface of the photovoltaic panel 1. The support rod 5 and the support block 6 structure ensure the smooth operation of the moving frame 2, providing a stable working foundation for the cleaning mechanism 4. This design realizes the covering movement of the cleaning components. Through the setting of the cleaning mechanism 4, a multi-level collaborative cleaning mode is adopted: the first water spray component 402 pre-wets and washes the surface dust, and the scraper 401 pushes away large particles of impurities; the cleaning brush 403 performs deep scrubbing with the assistance of the second water spray component 404; and the squeegee 405 finally scrapes away the sewage. Through staged treatment, it avoids scratching the surface with grit and improves cleaning efficiency.

[0027] For a specific embodiment two, please refer to Figures 1-5 Based on the first specific embodiment, the bottom of the movable frame 2 is provided with fixed through slots on both sides, the drive motor 302 is fixedly connected inside the drive through slots, the movable frame 2 is fixedly connected with support rods 5 on both sides, the support rods 5 are slidably connected with support blocks 6, the top of the support blocks 6 is fixedly connected to the bottom of the movable frame 2, there are two toothed plates 304, the two toothed plates 304 are fixedly connected to both sides of the movable frame 2 respectively, the first water spray assembly 402 includes a water spray plate 4021 fixedly connected to the top of the scraper plate 401, a first water pipe 4022 fixedly connected inside the water spray plate 4021, and a first nozzle 4023 connected to the surface of the first water pipe 4022, the movable frame 2 is provided with drainage through slots 7 on both sides, there are two cleaning brushes 403, the two cleaning brushes 403 are connected to the synchronous wheel through a servo motor, and the second water spray assembly 404 includes a second water pipe 4041 fixedly connected inside the movable frame 2, and a second nozzle 4042 connected to the bottom of the second water pipe 4041.

[0028] Specifically, the fixed through slot is used to fix the drive motor 302 inside the moving frame 2. The support rod 5 and support block 6 are used to support the moving frame 2, allowing the moving frame 2 to move smoothly along the direction of the support rod 5. The drive gear 303 and toothed plate 304 are used to drive the moving frame 2 to move on the surface of the photovoltaic panel 1. The first water spray assembly 402 sprays water on the surface of the photovoltaic panel 1 to rinse the surface dust and wet the impurities before the scraper 401 scrapes away the impurities, making it easier for the scraper 401 to scrape away the impurities on the surface of the photovoltaic panel 1. The drainage through slot 7 discharges the water scraped by the scraper 405 to both sides of the moving frame 2. The second water spray assembly 404 sprays water to rinse the surface of the photovoltaic panel 1 during the cleaning process of the cleaning brush 403.

[0029] The operation process of this embodiment is as follows: After the drive motor 302 starts, it drives the drive gear 303 to rotate. Through the meshing transmission with the toothed plates 304 on both sides, it pushes the cleaning frame 301 to move laterally along the surface of the photovoltaic panel 1. The sliding cooperation between the support rod 5 and the support block 6 ensures that the moving frame 2 runs smoothly and avoids deviation or vibration during the cleaning process, so that the cleaning mechanism 4 can cover the entire surface of the photovoltaic panel 1.

[0030] When the cleaning frame 301 moves, the first water spraying component 402 sprays water to wet the surface and rinse away loose impurities. The scraper 401 then pushes away large particles of dirt. The cleaning brush 403 performs deep scrubbing with the assistance of the second water spraying component 404. Finally, the scraper 405 scrapes away the residual sewage to complete the cleaning. The entire process is carried out through multi-stage coordinated treatment, which protects the surface of the photovoltaic panel 1 from damage and ensures the cleaning effect.
