[0002] Photovoltaic solar panels are installed on open ground or water, which can effectively utilize solar clean energy. At present, most of the domestic solar energy resources are concentrated in the deserts and dusty areas in the northwest. The dust accumulation caused by sand and dust has a huge impact on the efficiency of solar power generation. In order to ensure the efficiency of solar power generation, solar photovoltaic panels need to be cleaned regularly.

[0003] Photovoltaic panel cleaning methods include manual cleaning methods, component robot cleaning technology, and electric curtain dust washing technology. Manual cleaning and electric curtain dust washing technology are easily restricted by the site. In some sites, such as cleaning operations at high places in factories, cleaning operations on the water surface are difficult to operate, and are not suitable for cleaning large areas of photovoltaic solar panels. In addition, manual cleaning efficiency is low, and the damage to photovoltaic panels during the construction process is difficult to assess. In addition, the safety of manual cleaning of photovoltaic panels cannot be guaranteed. The cost of using robot cleaning technology is too expensive, and the one-time cleaning cost is a huge burden.

It has a simple structure and strong practicality, is not restricted by the site, is not easy to damage the photovoltaic panel, is not restricted by the use of the photovoltaic panel, and can clean the photovoltaic panel anytime and anywhere. It has a wide range of applications and high practical value.

[0030] like Figure 1-Figure 7 As shown, a new energy photovoltaic panel with automatic cleaning function comprises a photovoltaic panel body 1 and a support frame 2, support frames 2 are arranged on both sides of the photovoltaic panel body 1, and both sides of the photovoltaic panel body 1 are detachably connected to the support frame 2, a photovoltaic panel cleaning device is arranged on the support frame 2, and the photovoltaic panel cleaning device is arranged on one side of the support frame 2, and a cleaning brush body 3 is cantilevered across the cross-section of the photovoltaic panel body 1, and the photovoltaic panel cleaning device comprises a cleaning brush body 3, a sliding base 4, a driving mechanism and a ball screw 5, the bottom end center of the sliding base 4 is matched and connected to the ball screw 5, and the end of the ball screw 5 is connected to the output end of the driving mechanism, the cleaning brush body 3 is installed on the top side of the sliding base 4, and a plurality of bristles 11 are arranged on the bottom surface of the cleaning brush body 3, and the bristles face the upper surface of the photovoltaic panel body 1, and the driving mechanism drives the ball screw 5 to rotate when it works, so that the sliding base 4 slides back and forth on the ball screw 5, and drives the cleaning brush body 3 to clean the upper surface of the photovoltaic panel body 1.

[0031] like Figure 6 As shown, further, the new energy photovoltaic panel also includes a fixing plate 6 and a mounting groove 7. The fixing plate 6 is arranged at the center of the two side surfaces where the photovoltaic panel body 1 is connected to the support frame 2. The mounting groove 7 is arranged at the center of the side where the support frame 2 is connected to the photovoltaic panel body 1. The fixing plate 6 and the mounting groove 7 are plugged in.
