Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic panel cleaning, and specifically refers to a photovoltaic panel surface dust removal device. Background Art

[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 relies on photovoltaic panels to receive sunlight. The more sunlight received, the more electrical energy converted. When outdoor dust, stones, sand and other debris adhere to the surface of photovoltaic panels, it will affect the power generation efficiency of photovoltaic modules. Severe local coverage will also lead to the "hot spot effect", which greatly affects the conversion efficiency of photovoltaic modules.

[0003] Manual cleaning of photovoltaic panels is labor-intensive and inefficient. When using water to clean photovoltaic panels, the residual water on the photovoltaic panels needs to be wiped clean in time, otherwise it will not only affect the power generation efficiency of the photovoltaic panels, but also make the cleaned photovoltaic panels prone to dust adhesion again. In addition, for cold areas in winter, the residual water on the photovoltaic panels will freeze into ice, seriously affecting the power generation efficiency of the photovoltaic panels.

[0004] Therefore, a photovoltaic panel surface dust removal device is needed to solve the above problems. Summary of the invention

[0015] Further, a wiping cotton strip is arranged on the lower wall of the movable cavity.

[0016] The beneficial effects achieved by the present invention with the above structure are as follows:

[0017] 1. By using the meshing of the transmission gear and the transmission rack, the linkage plate, the guide rod and the shielding baffle are driven to move along the photovoltaic panel. At the same time, the first linkage shaft drives the first belt pulley to rotate. Through the transmission belt and the second belt pulley, the second linkage shaft, the rotating disk and the second magnet are driven to rotate. When the second magnet is aligned with the first magnet, the connecting plate and the movable plate are pushed upward, the air pressure in the gas cavity decreases, the heating belt is electrified, and the outside air flows along the air flow groove and then enters the gas cavity from the air hole. At this time, the air flow dries the photovoltaic panel between the air flow grooves. When the second magnet is staggered with the first magnet, the restoring spring pulls the spring baffle, the movable plate and the connecting plate downward. The movable plate pushes the air in the gas cavity out of the air hole, and the air enters the air flow groove and is discharged along the air flow groove. At this time, the hot air flow dries the photovoltaic panel between the air flow grooves;

[0018] 2. When the rotating disk rotates, when the notch on the rotating disk is aligned with the water inlet pipe and the connecting pipe, the water inlet pipe and the connecting pipe are in a connected state, and the water pump sucks the water in the water storage cylinder into the water inlet pipe, enters the notch of the rotating disk through the water inlet pipe, and then enters the connecting pipe and the fixed sleeve through the notch. The water pressure pushes the fixed sleeve forward, thereby driving the shielding plate, the movable cavity and the wiping cotton strip to wipe and clean the dirt on the photovoltaic panel, and the water in the fixed sleeve enters the movable cavity through the water outlet pipe, and then sprays out from the water spray hole, and the sprayed water is between the shielding plate and the linkage plate;

[0019] 3. The rotating disk continues to rotate. When the notch on the rotating disk is offset from the water inlet pipe and the connecting pipe, the water inlet pipe and the connecting pipe are not connected. At this time, the reciprocating spring pulls back the baffle plate, and the baffle plate drives the fixed sleeve to move. The water in the fixed sleeve enters the movable cavity through the outlet pipe and is sprayed out from the water spray hole. Therefore, during the rotation of the rotating disk, the baffle plate reciprocates on the guide rod, thereby wiping the slender surface to clean the photovoltaic panel.

[0045] As Figure 8 shown in the figure, a wiping cotton strip 24 is arranged on the lower wall of the movable cavity 45.

[0046] When in use, the transmission motor 40 is turned on, the transmission motor 40 drives the linkage shaft 1 36 to rotate, the linkage shaft 1 36 drives the driven bevel gear 35 to rotate, the driven bevel gear 35 drives the transmission shaft 33 to rotate, the transmission shaft 33 drives the transmission gear 31 to rotate, the transmission gear 31 is meshed with the transmission rack 30, and the transmission gear 31 moves along the upper edge of the photovoltaic panel 1, thereby driving the linkage plate 11, the guide rod 41 and the shielding plate 44 to move along the photovoltaic panel 1;

[0047] The linkage shaft 1 36 drives the pulley 1 37 to rotate at the same time, the pulley 1 37 drives the pulley 2 38 to rotate through the transmission belt 39, the pulley 2 38 drives the linkage shaft 2 28 to rotate, the linkage shaft 2 28 drives the rotating disk 25 to rotate, the rotating disk 25 drives the magnetic block 27 to rotate, when the magnetic block 27 is aligned with the magnetic block 1 26, the magnetic block 27 and the magnetic block 1 26 repel each other, push the connecting plate 15 upward, the connecting plate 15 drives the movable plate 12 to move upward, the air pressure in the gas chamber 20 is reduced, the heating belt 13 is energized, and the outside The air flows along the air flow groove 22, and then enters the gas cavity 20 from the air hole 23. At this time, the hot air flow dries the photovoltaic panels 1 between the air flow grooves 22. When the second magnetic block 27 and the first magnetic block 26 are offset, the return spring 19 pulls the spring baffle 18 downward, and the spring baffle 18 drives the movable plate 12 and the connecting plate 15 to move downward. The movable plate 12 pushes the air in the gas cavity 20 out of the air hole 23, and the air enters the air flow groove 22 and is discharged along the air flow groove 22. At this time, the hot air flow dries the photovoltaic panels 1 between the air flow grooves 22;

[0048] When the linkage shaft 28 drives the rotating disk 25 to rotate, when the notch 29 on the rotating disk 25 is aligned with the water inlet pipe 52 and the connecting pipe 43, the water inlet pipe 52 and the connecting pipe 43 are in a connected state, the water pump 51 is turned on, and the water pump 51 sucks the water in the water storage cylinder 4 into the water inlet pipe 52, enters the notch 29 of the rotating disk 25 through the water inlet pipe 52, and then enters the connecting pipe 43 through the notch 29, and enters the fixed sleeve 47 through the connecting pipe 43.

The water enters the movable cavity 45 and then sprays out from the water spray hole 50 on the movable cavity 45. The sprayed water is between the baffle plate 44 and the linkage plate 11, and the rotating disk 25 continues to rotate. When the notch 29 on the rotating disk 25 is staggered with the water inlet pipe 52 and the connecting pipe 43, the water inlet pipe 52 and the connecting pipe 43 are in a disconnected state, and the water pump 51 cannot send water into the connecting pipe 43 through the water inlet pipe 52. At this time, the reciprocating spring 46 pulls back the baffle plate 44, and the baffle plate 44 drives the fixed sleeve 47 to move back. The water in the fixed sleeve 47 enters the movable cavity 45 through the water outlet pipe 48, and then sprays out from the water spray hole 50 on the movable cavity 45. Therefore, during the rotation of the rotating disk 25, the baffle plate 44 reciprocates on the guide rod 41, so that the wiping cotton strip 24 reciprocates to wipe the photovoltaic panel 1;
