The working principle and the process are as follows: when the photovoltaic curved surface cleaning device does not work, the air bag 13 and the cleaning flannelette 1 are extruded into the flannelette recovery protection cover 3 at the upper end of the photovoltaic curved surface 2, and when the cleaning is needed, the cleaning is carried out. Firstly, two servo motors 7 arranged on two sides of the photovoltaic curved surface 2 are controlled to rotate, so that a screw rod 4 connected with the screw rod is driven to rotate, the screw rod 4 drives a screw rod sliding table 6 sleeved on the screw rod sliding table to move downwards in the rotating process, and the screw rod sliding table 6 drives a clamping plate 19 welded on the inner side of the screw rod sliding table to move downwards. As the U-shaped notch 19.3 on the clamping plate 19 is clamped on the fixing sleeve 15.2 outside the driving gear 15, the driving gear 15 is sleeved on the flannelette driving rotating shaft 5, and an upper and lower guide rail structure is formed between the driving gear 15 and the flannelette driving rotating shaft 5 through the convex spline 15.1 and the concave spline 5.1, when the driving gear 15 is subjected to downward acting force of the clamping plate 19, the driving gear 15 moves downwards along the flannelette driving rotating shaft 5. Meanwhile, the sharp-tooth chain 14 sleeved on the driving gear 15 is driven to move downwards and sleeved on the sharp-tooth chain 14, and the lower side edge of the cleaning flannelette 1 is fastened on the sharp-tooth chain 14, so that in the process that the sharp-tooth chain 14 and the driving gear 15 move downwards, the lower side edge of the cleaning flannelette is pulled to move downwards, and the cleaning flannelette is unfolded and tiled on the whole photovoltaic curved surface. Because the lower side edge of the air bag 13 is connected with the inner side edge of the clamping plate 19 through a rubber belt or a nylon belt, the air bag 13 is unfolded along with the screw rod sliding table 6 in the downward movement process, the width and the height of the air bag 13 are designed to be smaller than those of the cleaning flannelette and are arranged in the middle position of the air bag, and therefore the air bag is not influenced by the flannelette driving device after being unfolded. After the cleaning flannelette 1 is unfolded, the blowing and sucking dual-purpose fan 9 is started, and the air bag 13 is inflated through the air bag inflation tube 10. The inflated air bag 13 extrudes the cleaning flannelette 1 after being expanded, so that the cleaning flannelette 1 is tightly attached to the photovoltaic curved surface 2, and the concave surface part of the photovoltaic curved surface 2 can be cleaned. The direct current motor 8 is started, the direct current motor drives the flannelette driving rotating shaft 5 on two sides to rotate through the driving leather 12, the water pump is started simultaneously, the water pump pumps water in the ground water tank into the water spraying row 18, then the water is sprayed to the upper end of the photovoltaic curved surface 2 between the cleaning flannelette 1 and the photovoltaic curved surface 2 through the water spraying opening on the inner side of the water spraying row 18, the flannelette driving rotating shaft 5 transversely drives the cleaning flannelette 1 to rotate in the rotating process, and the cleaning of the photovoltaic curved surface 2 is completed in the transverse rotating process of the cleaning flannelette 1. After the washing is accomplished, direct current motor 8 and water pump are closed, reverse start blows and inhales dual-purpose fan 9, discharge the gas in gasbag 13, then reverse start servo motor 7 again, servo motor 7 antiport, and then drive lead screw slip table 6 upward movement, thereby drive gear 15, sharp tooth chain 14 and wash the lower limb upward movement of cotton flannel 1 with gasbag 13, thereby will wash cotton flannel 1 and the extrusion of gasbag 13 and accomodate the lower part at cotton flannel recovery safety cover 3, thereby can not influence the normal work of photovoltaic curved surface 2 at out-of-work in-process. Wherein, the end interface of the cleaning flannelette 1 can adopt detachable connection, thereby being convenient for replacement.
