Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic production, and in particular to a surface cleaning device for photovoltaic production. Background Art

[0002] Photovoltaic, or photovoltaic power generation, is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is one of the important forms of solar energy utilization. After the existing solar cells are assembled, the debris and dust generated during the assembly process will be scattered on the surface of the solar cells. If they are packaged and stacked without cleaning, the surface of the solar cells will be scratched, affecting the normal use of the solar panels.

[0003] At present, surface cleaning equipment occupies an important position in the process of photovoltaic production and maintenance. Utility model patent CN216655436 U discloses a surface cleaning device for photovoltaic production, which includes a frame, a conveyor belt, a cleaning component and a pair of collecting components. The cleaning component is arranged at the top of the frame to clean the solar panels located on the surface of the conveyor belt; the collecting components are arranged on both sides of the frame to collect impurities cleaned out by the cleaning component. This equipment cleans the surface of the solar panel in transmission through the cleaning component, avoiding the traditional manual cleaning method, improving the cleaning efficiency, and will not produce omissions, and the cleaning effect is better. At the same time, the collecting component can automatically collect the impurities cleaned out by the cleaning component, reducing the difficulty of later maintenance.

[0004] However, although the device has achieved certain results in improving cleaning efficiency, it still has obvious limitations in practical applications. Specifically, the equipment in the above technology can only clean and collect impurities, but the cleaning effect is not ideal for fine dust or difficult-to-remove dirt remaining on the surface of photovoltaic panels. These residual dust and dirt will still affect the photoelectric conversion efficiency of solar panels, thereby reducing the overall performance of photovoltaic power generation systems.

[0005] Therefore, in view of the shortcomings of the existing technology, we urgently need a surface cleaning device for photovoltaic production to solve this problem. This equipment should be able to more thoroughly remove dust from the surface of solar panels, improve the quality of cleaning, and maintain an efficient cleaning speed to better meet the needs of modern photovoltaic production and maintenance, and provide strong support for the sustainable development of the photovoltaic industry. Summary of the invention

[0006] The purpose of the present invention is to provide a surface cleaning device for photovoltaic production, which solves the problem that the prior art can only clean and collect impurities, but the cleaning effect is not ideal for the fine dust or difficult-to-remove dirt remaining on the surface of the photovoltaic panel.

The setting of the exhaust assembly 7 enables the blown debris and dust to be timely adsorbed and discharged, avoiding secondary pollution of dust and debris. At the same time, the coordinated setting of the exhaust channel 15 and the connecting channel 14 also improves the efficiency and effect of the exhaust, ensuring the smooth progress of the cleaning work.

[0053] Embodiment 3

[0054] See also Figure 1-7 As shown, in the present embodiment, a surface cleaning device for photovoltaic production is provided with guide plates 4 at the top of the conveyor belt 1 and on both sides of the interior of the mounting frame 3. The guide plates 4 are connected to the top of the conveyor belt 1 through positioning brackets 8. Specifically, guide plates 4 are provided at the top of the conveyor belt 1 and on both sides of the interior of the mounting frame 3. The guide plates 4 are connected to the top of the conveyor belt 1 through positioning brackets 8. When the solar panel moves on the conveyor belt 1, the guide plates 4 play a role of guiding and positioning, ensuring that the solar panel can enter the cleaning area smoothly and accurately. The setting of the guide plates 4 effectively prevents the solar panel from deflecting and shaking during movement, ensures the smooth progress of the cleaning work, and improves the accuracy and stability of the cleaning.

Specifically, the driving motor 19 is fixedly connected to the side wall of the vertical plate 16 with bolts, and its output end rotates through the vertical plate 16 and is connected to one end of the rotating rod 20. When the driving motor 19 is started, it drives the rotating rod 20 to rotate, and then drives the connecting bracket 17 and the cleaning brush 5 to rotate to perform cleaning work. The setting of the driving motor 19 provides a stable and reliable power source for the cleaning component 2, ensuring the smooth progress of the cleaning work. At the same time, the motor drive method also improves the efficiency and speed of cleaning.

[0059] This program has the following working process:
