The second expansion plate 113 is parallel to the first expansion plate 112, and the second expansion plate 113 is located on a side of the first expansion plate 112 away from the first connecting frame 140. The second frame body 114 is located at one end of the first telescopic plate 112 and the second telescopic plate 113 far away from the first frame body 111, the second frame body 114 is respectively connected with the first telescopic plate 112 and the second telescopic plate 113 in a rotating mode, the rotating axis of the second frame body 114 relative to the first telescopic plate 112 is parallel to the axis of the first brush roller 150, and the rotating axis of the second frame body 114 relative to the second telescopic plate 113 is parallel to the axis of the first brush roller 150.

Referring to fig. 6 and 10, the first brush roller 150 is rotatably coupled to the first coupling frame 140, and a rotation axis of the first brush roller 150 is perpendicular to a length direction of the photovoltaic panel 210. The first gear 160 is respectively installed at two ends of the first brush roller 150, the first rack 170 for matching with the first gear 160 is installed on the outer frame 220 of the photovoltaic panel 210, the first rack 170 is installed at the top of the outer frame 220 of the photovoltaic panel 210, and the first rack 170 is meshed with the first gear 160, so that when the first brush roller 150 moves relative to the photovoltaic panel 210, the rotating direction of the position where the first brush roller 150 contacts with the photovoltaic panel 210 is the same as the moving direction of the first brush roller 150.

In this embodiment, the first connecting frame 140 is located between the outer frames 220 on both sides of the photovoltaic panel 210, and the first connecting frame 140 is slidably connected to the outer frames 220. The outer frame 220 of the photovoltaic panel 210 is provided with a guide groove which penetrates the outer frame 220 in the thickness direction of the outer frame 220 and extends in the longitudinal direction of the photovoltaic panel 210. The first rack 170 is disposed at an outer side of the outer frame 220, and the first gear 160 is disposed at a portion of the first brush roller 150 extending out of the outer frame 220, that is, the outer frame 220 of the photovoltaic panel 210 is located between the first gear 160 and the first connection frame 140, and the first connection frame 140 and the first gear 160 and the first rack 170 can be separated by the outer frame 220 of the photovoltaic panel 210. This can prevent dust on the photovoltaic panel 210 from falling between the first rack 170 and the first gear 160 when being lifted up, thereby ensuring long-term stable engagement of the first rack 170 and the first gear 160.

Referring to fig. 7 and 8, the first connecting frame 140 is provided with a first scraper 180, a first dust guide plate 190, a first elastic member (not shown), and a second elastic member (not shown). The first scraper 180 is located at a side of the first link frame 140 facing the rotary disk 120, i.e., the first scraper 180 is located below the first link frame 140. The first scraper 180 is slidably connected to the first connecting frame 140, and a sliding direction of the first scraper 180 is perpendicular to the photovoltaic panel 210. The two ends of the first elastic member are respectively connected with the first connecting frame 140 and the first scraper blade 180, and the first elastic member makes the first scraper blade 180 have a tendency to slide in a direction away from the photovoltaic panel 210.

When installed, the axis of the rotary disk 120 is located on the center line of the first link frame 140, and the first link 130 is connected to the middle of the first link frame 140. A first groove 181 is formed in a position where the first scraper 180 corresponds to the first connecting rod 130, one end of the first groove 181 is spaced from an end of the first scraper 180, the other end of the first groove 181 extends to a middle position of the first scraper 180, and when the first connecting rod 130 is clamped into the first groove 181, the first scraper 180 is separated from the photovoltaic panel 210. Referring to fig. 2, when the rotating disc 120 rotates to the two sides of the axis of the rotating disc 120, the first connecting rod 130 abuts against the top of the first scraper blade 180, and at this time, the first scraper blade 180 overcomes the acting force of the first elastic element and approaches to the photovoltaic panel 210, and abuts against the photovoltaic panel 210, and when the first connecting rod 130 drives the first connecting frame 140 to move, the first scraper blade 180 can scrape the photovoltaic panel 210, so as to clean the relatively tight impurities attached to the photovoltaic panel 210. Referring to fig. 3, when the rotating disc 120 rotates to the same side of the axis of the rotating disc 120 as the first connecting rod 130 and the first groove 181 are located, the first connecting rod 130 is clamped in the first groove 181, and at this time, the first scraper 180 moves away from the photovoltaic panel 210 under the action of the first elastic member and is separated from the photovoltaic panel 210. In a specific using process, the rotating disc 120 is made to rotate counterclockwise in fig. 2, in this process, when the rotating disc 120 rotates to the position in fig. 2 and continues to rotate, the first connecting frame 140 and the first scraper blade 180 move towards the lower side of the photovoltaic panel 210, and at this time, the first scraper blade 180 contacts with the photovoltaic panel 210, and at this time, the photovoltaic panel 210 is cleaned in a direction of "scraping before brushing"; when the rotating plate rotates to the position of fig. 3 and continues to rotate, the first connecting frame 140 and the first scraper blade 180 move towards the upper side of the photovoltaic panel 210, at this time, the first scraper blade 180 is separated from the photovoltaic panel 210, and at this time, the photovoltaic panel 210 is cleaned only by the first brush roller 150.

Referring to fig. 9, in the present embodiment, the first notch 181 extends from the middle position of the first scraper 180 toward the edge portion of the first scraper 180, and the recessed depth of the first notch 181 gradually increases from the middle position of the first scraper 180 toward the edge position thereof. Thus, when the first connecting rod 130 is engaged with the first groove 181, the first scraper 180 can move away from the photovoltaic panel 210 and approach the photovoltaic panel 210. Specifically, when the first link frame 140 moves, the distance from the first scraper 180 to the photovoltaic panel 210 gradually increases in the process that the first link frame 140 moves toward the upper side of the photovoltaic panel 210 from the position where the first link frame 140 is located below the photovoltaic panel 210, and the distance from the first scraper 180 to the photovoltaic panel 210 increases to the maximum by the time the first link frame 140 moves to the middle position of the photovoltaic panel 210; then, the first scraper 180 gradually approaches towards the photovoltaic panel 210, and when the first connecting frame 140 moves to the upper side of the photovoltaic panel 210, the first scraper 180 just abuts against the photovoltaic panel 210. The first scraper blade 180 is moved away from the photovoltaic panel 210 in a slow moving manner and then approaches the photovoltaic panel 210, so that the first scraper blade 180 and the photovoltaic panel 210 are prevented from being in relatively strong collision, and the photovoltaic panel 210 is prevented from being damaged.
