Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panel cleaning, and in particular is a photovoltaic solar panel cleaning device and a use method thereof. Background Art

[0002] As the world energy crisis becomes more and more serious, people gradually turn their attention to the field of new energy. At the peak of the booming development of new energy, electric energy is mainly used to replace other energy sources to continuously occupy new commanding heights. At present, the electric energy in the field of new energy mainly stores or converts other forms of energy into electric energy for people to use. Among the many conversion methods, the application of solar energy conversion into electric energy is very convenient and very wide.

[0003] Photovoltaic solar panels are mainly used to convert solar energy into electrical energy. When the weather is clear and there is plenty of sunlight, photovoltaic solar panels absorb sunlight and convert light energy into solar energy that can be directly used by people through the electronic components on the solar panels, or store the converted electrical energy in batteries.

[0004] Although solar panels can convert electrical energy into electricity that can be used by people, photovoltaic solar panels are exposed to the open air for a long time. As time goes by, dust or debris in the air will continue to accumulate on the surface of the solar panels. When the dust accumulated on the surface of the solar panels reaches a certain level, the sunlight will be blocked by the dust and cannot shine on the surface of the solar panels, seriously affecting the working efficiency of the solar panels.

[0005] At present, photovoltaic solar panels are mainly a thin layer of black glass-like material, which contains electronic components. The more sunlight shines on the black glass surface, the more electricity is generated. When dust accumulates on the black glass surface, it will affect the working efficiency of photovoltaic solar panels. At present, solar panels are mostly installed on the top of houses, or other taller buildings, or in open areas, such as lakes, open fields, and deserts. The location of photovoltaic panels is usually high, which is not easy for workers to enter or poses a personal safety hazard. Therefore, when a lot of dust accumulates on the surface of solar panels that have been working for a long time, how to clean the dust on the surface of solar panels has become an urgent problem that needs to be solved.

[0006] For example, a Chinese invention patent with an authorization announcement date of 2024.08.06 and an authorization announcement number of CN118232824B discloses an automatic cleaning device for new energy photovoltaic panels, including a shell, which can be clamped on the photovoltaic panel body and can move along the photovoltaic panel body; a cleaning cavity is opened inside the shell; a cleaning roller is arranged in the cleaning cavity, and bristles are arranged on the outside of the cleaning roller; a cleaning opening connected to the cleaning cavity is opened at the bottom of the shell corresponding to the position of the cleaning roller, and the bristles can extend out of the cleaning opening and abut against the surface of the photovoltaic panel body, and a connected water collection tank and a sewage pipe are arranged in front of the cleaning roller inside the shell, the water collection tank is close to the cleaning roller and connected to the cleaning cavity, and a water inlet pipe is arranged inside the cleaning cavity, and the water inlet pipe is located behind the cleaning roller, and the water inlet pipe is used to spray water to the cleaning roller.

[0007] In the above-mentioned prior art, the photovoltaic panel is brushed by a cleaning roller. However, after long-term use, impurities, bird droppings, etc. are easily retained on the bristles of the cleaning roller. The bristles need to be cleaned or replaced frequently, which increases labor costs and cleaning costs and reduces work efficiency. In the process of cleaning, the bristles may be caught in sharp impurities and continue to rotate on the surface of the photovoltaic panel, which may scratch the photovoltaic panel and cause damage to the photovoltaic panel. Summary of the invention

[0015] Furthermore, the movable base comprises a U-shaped base, and a plurality of the nozzles are disposed on the upper surface and the side surfaces of the U-shaped base.

[0016] Furthermore, the nozzle is connected to the water supply pipe through a connecting pipe, the water supply pipe is wound on the retractable disk and connected to the water storage unit, the retractable disk follows the movement of the mobile water spraying assembly through the moving trolley, when the mobile base is translated from AB to CD, the retractable disk lengthens the water supply pipe, and when the mobile base is translated from CD to AB, the retractable disk retracts the water supply pipe, thereby ensuring that the length of the water supply pipe of the entire system is in an optimal state during operation, preventing tangling caused by clutter and affecting work efficiency.

When stains are observed on the surface of the photovoltaic panel, adjust the angle between the nozzle and the photovoltaic panel and spray water on the photovoltaic panel; S3: When the stains are stubborn, turn on the booster unit and adjust the angle between the nozzle and the photovoltaic panel again to give a high-pressure impact to the stubborn stains. S4: The wastewater flows to the sump at the bottom of the photovoltaic panel for recycling and treatment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1, a photovoltaic solar panel cleaning device, such as Figure 1 As shown, it includes a track 2 set along the photovoltaic panel 1, and a mobile water spray component 3 is moved along the track 2 by a driving unit 1.

[0026] Specifically, when a large amount of dust accumulates on the surface of the photovoltaic panel 1 after a long period of operation, which affects the photovoltaic panel 1 from converting light energy into electrical energy, it needs to be cleaned, and sufficient water is filled in the water storage unit 14.
