Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic component maintenance, and in particular to a photovoltaic component visual cleaning system and cleaning method. Background Art

[0002] Photovoltaic power generation is a renewable energy technology that converts solar energy into electrical energy. It generates direct current by shining sunlight on photovoltaic modules, and then converts the direct current into alternating current for use through an inverter. In deserts or similar sandy environments, there is sufficient sunlight, which is suitable for photovoltaic power generation and can effectively utilize this natural resource. Sandy environments are prone to produce sand and dust covering the surface of photovoltaic modules, reducing the area of ​​sunlight shining on photovoltaic cells, resulting in a decrease in the efficiency of converting light energy into electrical energy. In order to maintain the high efficiency of photovoltaic modules, it may be necessary to clean the photovoltaic panels more frequently. Due to the special environment of sandy land, it is not convenient to use water resources for cleaning. Directly use a rotating cleaning brush for cleaning. When the rotating brush contacts the surface of the photovoltaic panel, the friction and rotational motion will cause the attached sand and dust particles to be lifted up, and the sand and dust particles will return to the photovoltaic modules that have been cleaned, which will cause secondary pollution. This causes unnecessary impact on the photovoltaic components with cleaned surfaces and reduces the power generation efficiency of the photovoltaic panels. Secondly, a dust accumulation area will be formed on the inner side of the bottom frame of the photovoltaic panel, which is prone to accumulate dust, sand and other particles. Traditional rotating brushes are usually designed for flat surfaces and it is difficult to effectively enter the inside of the frame to clean the sand and dust particles.

[0030] A cleaning method used by a photovoltaic component visual cleaning system comprises the following steps: S1. First, the sand accumulation status on the surface of the photovoltaic module is monitored in real time through an external camera. When the accumulation of sand and dust is too large and affects the power generation of the photovoltaic module, the cleaning signal will be transmitted to the cleaning device to clean the sand and dust; S2, the cleaning device receives the cleaning signal and controls the driving device 8 to operate, and drives the cleaning device to move along the photovoltaic bracket 1 and the solar photovoltaic panel 2 through the driving device 8; S3, adjusting the angle of the spiral cleaning brush 603 through the tilt adjustment component 5 according to the cleaning needs, which helps to quickly discharge the sand and dust; S4, using the frame dust cleaning device 7 to clean the dust particles gathered on the bottom frame of the solar photovoltaic panel 2, so as to prevent the dust particles from gathering on the bottom frame of the solar photovoltaic panel 2; S5. As the cleaning device moves, the dust on the surface of the photovoltaic panel is cleaned and transported by the dust self-cleaning synchronous transport device 6 and discharged from the bottom to avoid the dust particles being carried to the surface of the solar photovoltaic panel 2 after cleaning to cause secondary pollution.

[0031] Working principle: First, the driving device 8 drives the cleaning device to move slowly along the outer frame of the photovoltaic bracket 1 and the solar photovoltaic panel 2. When the frame dust cleaning device 7 moves to the corner of the frame of the solar photovoltaic panel 2, the lifting cylinder 714 is controlled to start. Fig. 9 As shown, the driving end of the lifting electric cylinder 714 extends through the lifting frame 703 to drive the lifting column 704 and the vertical cleaning brush 705 to descend, so that the vertical cleaning brush 705 contacts the inner side of the photovoltaic panel frame, as shown in FIG. Figure 5 , Figure 6 As shown, the second motor 617 is then controlled to start, and the driving end of the second motor 617 drives the driving shaft 616 to rotate counterclockwise. The driving shaft 616 drives the transmission shaft 614 and the sliding shaft 613 to rotate through the second universal coupling 615. The sliding shaft 613 drives the cleaning shaft 602 to rotate through the first universal coupling 612. The rotation of the cleaning shaft 602 drives the spiral cleaning brush 603 to rotate counterclockwise synchronously. The spiral cleaning brush 603 rotates counterclockwise to sweep the sand and dust accumulated on the surface of the photovoltaic panel to the right. The sand and dust are lifted to the upper right by the action of the spiral cleaning brush 603. The lifted sand and dust hit the inner wall of the cleaning guide arc frame 601 and move to the top of the arc sand guide plate 610 under its reaction force, as shown in FIG. Figure 2 As shown, since the photovoltaic panel is installed at an angle, the cleaning guide arc frame 601 is kept parallel to the photovoltaic panel. Figure 8As shown in FIG. 6 , the sand and dust in the cleaning guide arc frame 601 will move downward along the arc sand guide plate 610 and be discharged from the sand discharge pipe 611, as shown in FIG. Figure 7 As shown, the cleaning shaft 602 drives the driven shaft 604 to rotate through the synchronous wheel transmission group during the rotation process, and the driven shaft 604 drives the lifting plate 607 to move up and down slightly under the action of the fixed limit rod 606 and the return spring 608 through the cam 605. The lifting plate 607 drives the arc-shaped sand guide plate 610 to move up and down slightly in the cleaning guide arc frame 601 through the connecting rod 609, so as to promote the discharge of sand and dust on the arc-shaped sand guide plate 610. Fig.10 As shown, the driving shaft 616 drives the third rotating shaft 715 to rotate synchronously through the synchronous wheel transmission group during the rotation process, and the third rotating shaft 715 drives the second rotating shaft 708 to rotate through the third bevel gear 716 and the fourth bevel gear 717. Fig. 9 As shown, the second rotating shaft 708 drives the first rotating shaft 706 to rotate through the first bevel gear 709 and the second bevel gear 710, and the first rotating shaft 706 drives the vertical cleaning brush 705 to rotate synchronously through the lifting column 704, and the dust inside the frame is cleaned by the rotation of the vertical cleaning brush 705. When too much dust accumulates at the corner of the frame of the solar photovoltaic panel 2, the driving end of the third motor 711 can be controlled to rotate, and the third motor 711 drives the reciprocating threaded rod 712 to rotate. The reciprocating threaded rod 712 drives the vertical cleaning brush 705 to move back and forth horizontally through the guide block 713 and the sliding plate 702, so as to expand the cleaning area at the corner of the frame. Before the cleaning device works, the angle of the spiral cleaning brush 603 can be controlled according to the cleaning needs, such as Figure 5 As shown, the No. 1 motor 510 is controlled to drive the one-way threaded rod 508 to rotate clockwise, and the one-way threaded rod 508 drives the guide slider 509 to move away from the No. 1 motor 510 under the action of the guide rod 511. The guide rod 511 drives the rotating shaft 504 to rotate counterclockwise through the swing frame 506. The rotating shaft 504 drives the two guide frames 503 and the corresponding adjustment plate 502 to move synchronously in the opposite direction under the guidance of the arc guide rail 501 through the rotating frame 505. The adjustment plate 502 drives the spiral cleaning brush 603 to rotate and adjust the angle around the rotating shaft 504 through the fixed rod 512, the cleaning guide arc frame 601 and the cleaning shaft 602. For reverse adjustment, the No. 1 motor 510 can be controlled to rotate in the opposite direction.
