Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic power generation technical field, concretely relates to a roof photovoltaic power station structure convenient to clean. BACKGROUND

[0002] As one of the important forms of solar energy utilization, roof photovoltaic power station not only can effectively utilize the idle space of building roof and reduce the occupation of land resources, but also can convert solar energy into electricity through photoelectric conversion technology to provide green and sustainable energy supply for buildings. Roof photovoltaic power station is exposed to outdoor environment for a long time, and is easily polluted by natural factors such as wind sand, rain, bird droppings, etc. If it cannot be cleaned in time, it will lead to the increase of dust and shelter on the surface of photovoltaic module, and further reduce the power generation efficiency, affecting the operation performance and economic benefit of the whole photovoltaic power station. Therefore, the roof photovoltaic power station needs to be cleaned regularly to keep the surface of photovoltaic module clean to ensure the best sunlight absorption efficiency and photoelectric conversion efficiency.

[0003] Some existing roof photovoltaic power stations lack flushing function in the cleaning mechanism, and the stubborn stains cannot be softened in advance during the cleaning process, which is easy to cause wear and tear to the brushing device, and is not conducive to further improving the cleaning effect.

[0004] For example, the roof distributed photovoltaic power station disclosed in the patent with the announcement number CN217769582U, in the use process of the roof distributed photovoltaic power station of the patent, the driving motor is started regularly by the single-chip microcomputer, the sliding frame moves to the right, and the bristle pad rotates at the same time. Through the friction between the bristle pad and the transparent wear-resistant plate, the stubborn stains on the surface of the transparent wear-resistant plate are separated from the transparent wear-resistant plate, and then the dust and stains are scraped to the right by the scraping plate, so that the dust and stains are separated from the surface of the transparent wear-resistant plate from the right side, the time required for cleaning the stubborn stains is reduced, the cleaning efficiency of the dust is increased, and the normal work of the solar power generation panel is ensured in the environment with too much dust on the roof.

[0005] Although the wiping mechanism of the above-mentioned roof distributed photovoltaic power station is designed ingeniously, and most of the dust and stains on the surface of the transparent wear-resistant plate can be effectively removed through the cooperation of the bristle pad and the scraping plate, the cleaning efficiency and the power generation efficiency of the photovoltaic panel are indeed improved, but there are still some aspects that can be further optimized and improved, especially when dealing with stubborn dirt. In the current design, only the physical friction of the bristle pad and the scraping of the scraping plate are used to remove the stains, which may not be effective for stubborn dirt (such as oil stains, bird droppings, etc.) attached to the transparent wear-resistant plate. These stubborn dirt needs to be softened and removed by washing with water or other cleaning agents. Without the flushing function, the stains cannot be softened in advance during the cleaning process, which may increase the wear and tear of the bristle pad, and at the same time reduce the cleaning efficiency and effect.

[0006] Therefore, it is necessary to invent a rooftop photovoltaic power station structure that is easy to clean to solve the above problems. Utility Model Content

Solenoid valves 12 are installed at the input ends of the No. 1 water supply pipe 6 and the No. 2 water supply pipe 8.

[0036] In one aspect of this embodiment, the number of the No. 1 nozzle 7 and the No. 2 nozzle 10 are both set to multiple, and the multiple No. 1 nozzles 7 are distributed in a linear array on the surface of the No. 1 water supply pipe 6, and the multiple No. 2 nozzles 10 are distributed in a linear array on the surface of the No. 2 water supply pipe 8.

As the loading rack 3 moves, the silicone strip at the bottom of the wiper 9 can scrape off the residual moisture and stains on the surface of the solar panel 2, so that the surface of the solar panel 2 remains dry and clean. When the cleaning of the entire solar panel 2 area is completed, the electric push rod 11 will restore the loading rack 3 to its original position under the control of the single-chip microcomputer 17.
