[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Photovoltaic power generation mainly generates electricity through sunlight, which requires that the photovoltaic power generation device be placed outdoors for a long time.

[0003] When photovoltaic power generation devices are placed outdoors for a long time, dust is likely to adhere to the surface of the photovoltaic panels, causing the photovoltaic panels to have a lower power generation efficiency. Traditional photovoltaic panel dust removal usually uses manual cleaning, which requires a lot of manpower. The traditional dust removal method is to wipe with tools. After multiple dust wiping, the tools need to be cleaned before they can be used again, which increases the workload of the staff. Summary of the invention

[0025] See also Figure 2-5 The linear module 103 can drive the rotating ring 705 to perform reciprocating linear motion, and the gear 701 is meshed and connected with the rack 105, so that the cleaning structure can perform reciprocating motion and rotation.

[0026] See also Figure 4-5 The blowing device 8 and the airbag 9 in the middle of the circular hole 6 opened in the middle of the adjacent limiting plate 5 are arranged alternately, and the inner material of the airbag 9 is elastic rubber, so that the dust on the surface of the photovoltaic power generation module 102 can be removed as a whole, and the airbag 9 can be reset actively. The cavity 702, the transfer tube 704, the cylindrical cavity 707 and the through hole 709 are connected, and the filter screen is detachably connected in the middle of the through hole 709, so that the gas inside the cylindrical shell 2 can be replenished, and the inside of the cylindrical shell 2 is not easy to be dusty.

[0027] See also Figure 2-9 The support block 801 is fixedly connected to the circular hole 6, and the two ends of the tension spring 807 are respectively fixedly connected to the first annular protrusion 803 and the support block 801, so that the blowing device 8 can blow out airflow, and the blowing device 8 can be reset under the action of the tension spring 807. The two wedge blocks 806 gradually reduce the cross section of the end of the L-shaped air channel 805 away from the cylindrical shell 2, and the photovoltaic power generation module 102 and the linear module 103 are electrically connected, so that the flow rate of the airflow blown out by the blowing device 8 is increased, and the photovoltaic power generation module 102 can control the opening and closing of the linear module 103.

[0028] When the sunlight intensity is sufficient and the power generation of the photovoltaic power generation module 102 is less than the normal value within a certain period of time, the photovoltaic power generation module 102 sends an electrical signal to the linear module 103, and the linear module 103 drives the rotating ring 705 to do reciprocating motion, and the rotating ring 705 drives the cleaning structure to move. At the same time, the rack 105 drives the gear 701 to rotate, and the gear 701 drives the cylindrical shell 2 to rotate through the linkage device 7. During the rotation of the cylindrical shell 2, the limit plate 5 drives the blowing device 8 and the air bag 9 to move. When the blowing device 8 and the air bag 9 come into contact with the photovoltaic power generation module 102 , the photovoltaic power generation module 102 squeezes the airbag 9, and at the same time, the photovoltaic power generation module 9 pushes the block 802 into the cylindrical shell 2. At this time, the internal pressure of the cylindrical shell 2 increases, and at the same time, the rubber plug 711 is pushed by the air pressure to the side of the cylindrical cavity 707 away from the gear 701. At this time, the rubber plug 711 blocks the strip airway 708, the limit plate 5 continues to move, and the block 802 continues to move into the cylindrical shell 2. When the bottom end of the L-shaped airway 802 moves through the support block 801, the gas inside the cylindrical shell 2 is ejected through the L-shaped airway 802, and the photovoltaic power generation module 102 is ejected. The cylindrical shell 2 continues to rotate, and the limit plate 5 drives the blowing device 8 and the airbag 9 to no longer contact the surface of the photovoltaic power generation module 102. Under the action of the tension spring 807, the block 802 moves to the side away from the cylindrical shell 2. At the same time, the airbag 9 restores its original shape under the action of elasticity. At this time, the inside of the cylindrical shell 2 is in a negative pressure state, and the external atmospheric pressure pushes the rubber plug 711 to the position of the limit ring 710. At this time, the strip airway 708 is no longer blocked, and the external gas enters the cylindrical shell 2; The dust cleaning structure continuously moves to perform a jet-jet dust removal operation on the surface of the photovoltaic power generation module 102, and the dust blown up on the surface of the photovoltaic power generation module 102 is discharged through the dust outlet 106; When the sunlight intensity is sufficient and the power generation of the photovoltaic power generation module 102 returns to normal within a certain period of time, the photovoltaic power generation module 102 controls the linear module 103 to reset and stop moving. The dust on the surface of the photovoltaic power generation module 102 is removed by the dust cleaning structure, and the dust cleaning structure does not need to be cleaned later, thereby reducing the workload of the staff.
