[0024] The mounting plate 15 is slidably arranged on the mounting frame 7 , and a driving mechanism for driving the mounting plate 15 to slide is installed on the mounting frame 7 .

[0025] Specifically, the drive mechanism includes a screw 13. Two mounting blocks are fixedly disposed on the sun-facing surface of the top of the mounting frame 7. The screw 13 is located between the two mounting blocks and is rotationally connected to them. A movable block 14 is fixedly disposed on the mounting plate 15 and slidably abuts against the mounting frame 7. The screw 13 extends through the movable block 14 and is threadedly connected thereto. A third motor 12 is fixedly mounted on the mounting frame 7, and its output shaft is coaxially fixedly connected to the screw 13.

[0026] A dust cleaning plate 23 is mounted on the mounting plate 15. The dust cleaning plate 23 slides in contact with the sun-facing side of the photovoltaic panel 38, with the sliding direction of the dust cleaning plate 23 being perpendicular to the sliding direction of the mounting plate 15. A linkage mechanism is mounted on the mounting plate 15, which is linked to the drive mechanism and is in transmission connection with the dust cleaning plate 23.

[0027] Specifically, the linkage mechanism includes a first gear 17, a second gear 21, a second rack 22, and a third rack 24.

The second rack 22 and the third rack 24 both mesh with the second gear 21.

[0030] The first rack 11 is fixedly mounted on the mounting frame 7 , and the first gear 17 is engaged with the first rack 11 .

[0031] Mounting plate 15 defines an air cavity, with a piston plate 26 slidably mounted in the center of the cavity. The cavity communicates with a clearance slot for the support shaft, which is fixedly connected to piston plate 26. Piston plate 26 blocks the clearance slot, and a guide block 20 is fixedly positioned in the center of piston plate 26. Guide block 20 extends through piston plate 26 and mounting plate 15, slidingly engaging with the mounting plate 15 in a limited position. Piston plate 26 blocks the sliding engagement between guide block 20 and mounting plate 15.

[0032] Both ends of the air cavity are fixed and connected to an air suction pipe 27 with a one-way valve and an air blowing pipe 28 with a one-way valve. The air blowing pipe 28 is provided with an air blowing hole 29, which faces the cleaning plate 23 and the photovoltaic panel 38.

[0033] Two mounting boxes 30 are fixedly mounted on the mounting plate 15, each of which contains a water bag 31. The dust removal plate 23 is fixedly connected to the two pressure plates 25 that squeeze the water bags 31. The second rack 21 is located between the two pressure plates 25 and is fixedly connected to the two pressure plates 25. A water spray pipe 32 with a one-way valve and a water inlet pipe 34 with a one-way valve are fixedly mounted on each mounting box 30. Each water spray pipe 32 and water inlet pipe 34 are connected to the water bag 31 in the mounting box 30. A nozzle 33 is fixedly mounted on each water spray pipe 32, and the nozzle 33 faces the photovoltaic panel 38. The two water inlet pipes 34 are connected to the same water tank 37, which is fixedly mounted on the base 1.

[0034] The mounting frame 7 is tilted and faces the sun. A water receiving box 35 is fixedly provided on the swivel seat 5. The water receiving box 35 is positioned at the low end of the mounting frame 7 and the box opening is positioned at the bottom of the mounting frame 7. The photovoltaic panel 38 is tilted towards the box opening of the water receiving box 35.

[0035] The water receiving box 35 is communicated with the water tank 37 via a return pipe 36. A filter screen is fixedly installed at the box opening of the water receiving box 35.

[0036] Working principle: When using this slope roof photovoltaic power generation equipment to generate electricity, the inclination angle of the mounting frame 7 can be adjusted by starting the first motor 2 and the second motor 8, and the mounting frame 7 can be adjusted to always face the sun.

[0037] The adjustment process is as follows: When the first motor 2 is started, its output shaft drives the worm 3 to rotate. The worm 3 drives the worm gear 4, which in turn drives the rotating base 5. The rotating base 5, through two fixed blocks, drives the horizontal shaft 6 to rotate in accordance with the sun. The horizontal shaft 6 drives the mounting bracket 7 to rotate in accordance with the sun. The mounting bracket 7 drives the photovoltaic panel 38 to rotate in accordance with the sun.

[0038] When the second motor 8 is started, the output shaft of the second motor 8 drives the first hinge rod 9 to rotate, the first hinge rod 9 drives the second hinge rod 10, and the second hinge rod 10 drives the mounting frame 7 to rotate up and down in the vertical direction. The mounting frame 7 drives the photovoltaic panel 38 to always face the sun.

[0039] When the photovoltaic panel 38 needs to be cleaned, the third motor 12 is started, and its output shaft drives the screw 13 to rotate. The screw 13 pushes the moving block 14 to move, which in turn drives the mounting plate 15 to move along the mounting bracket 7. The mounting plate 15 drives the dust cleaning plate 23 to slide along the sun-facing side of the photovoltaic panel 38, thereby scraping away dust accumulated on the sun-facing side of the photovoltaic panel 38.

[0040] As mounting plate 15 moves along mounting bracket 7, it rotates first gear 17. Because first gear 17 meshes with first rack 11, first rack 11 pushes first gear 17 to rotate. First gear 17 then rotates first transmission rod 18, which in turn pushes second transmission rod 19 via a connecting shaft. Second transmission rod 19 pushes the support shaft to slide along the clearance slot, which in turn moves second gear 21.

[0041] When the second gear 21 moves, it meshes with the third rack 24, causing the third rack 24 to rotate the second gear 21, which in turn drives the second rack 22 to move. The movement of the second rack 22 drives the dust removal plate 23 toward the screw 13. The movement of the support shaft drives the piston plate 26 toward the screw 13. The piston plate 26 pushes the air in the air cavity out of the air outlet pipe 28 near the screw 13. The air is blown through the air holes 29 in the air blow pipe 28 toward the dust removal plate 23 and the photovoltaic panel 38.

[0042] At the same time, external air enters the air cavity through the air intake pipe 27 away from the screw rod 13.

[0043] As the second rack 12 gradually moves closer to the screw rod 13, it drives the pressure plate 25 into the corresponding mounting box 30 and squeezes the corresponding water bag 31. The water in the water bag 31 is then sprayed out of the nozzle 33 through the spray pipe 32. The sprayed water washes away dust and stains on the photovoltaic panel 38 and dust adhering to the dust cleaning plate 23. The wastewater then flows through the sun-facing side of the photovoltaic panel 38 to the water receiving tank 35, where it is filtered by a filter at the inlet of the water receiving tank 35. The filtered wastewater then flows back into the water tank 37 through the return pipe 36, thus completing the water circulation process.

[0044] When the mounting plate 15 slides to the lowest end of the mounting frame 7, the output shaft of the third motor 12 reverses, driving the screw 13 in reverse. The screw 13 pushes the movable block 14 back, which in turn drives the mounting plate 15 back, ultimately returning to the upper end of the mounting frame 7. During this process, the piston plate 26 slides away from the screw 13, and the air in the air cavity is blown out through the blow hole 29 on the blow pipe 28 away from the screw 13. External air enters the air cavity through the suction pipe 27 near the screw 13. Simultaneously, the second rack 22 drives the corresponding pressure plate 25 to move into the mounting box 30 away from the screw 13, squeezing the water bag 31 inside the mounting box 30. Simultaneously, the second rack 22 drives the pressure plate 25 near the screw 13 to disengage the squeezed water bag 31. During this process, the water bag 31 in the mounting box 30 near the screw 13 returns to its original state, and the water in the water tank 37 flows into the restored water bag 31 through the water inlet pipe 34.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
