And when the second motor drives the second winding drum to rotate, the second winding drum wins and recovers the second pull rope, and the scraper trolley is pulled to slide towards the other side of the guide rail assembly through the second pull rope.
In the practical application process, the motor driving device can drive the first winding drum or the second winding drum to rotate, the first winding drum or the second winding drum rotates to wind and unwind the rope, the scraper trolley is pulled to move, and the scraper 22 is cleaned on the photovoltaic panel 4.
As shown in fig. 3, the doctor assembly 2 includes: the beam 21 is connected between the two scraper trolleys, and the scraper 22 is arranged on the beam 21, and the two scraper trolleys press the scraper 22 on the beam 21 against the surface of the photovoltaic panel 4 assembly;
as shown in fig. 2, each photovoltaic panel 4 in the assembly of photovoltaic panels 4 may also have a problem of straightness, that is, two adjacent photovoltaic panels 4 are not flush, and the length of each scraper 22 in the length direction of the cross beam 22 is long, so that the area swept by each scraper when the cross beam 21 moves covers all the photovoltaic panels 4, so that the scraper 22 can completely clean the surfaces of all the photovoltaic panels 4, there is no photovoltaic panel 4 which is not cleaned locally, and the cleaning effect is good.
As shown in fig. 2, the scrapers 22 are disposed in a strip shape, and a first preset angle is formed between the length direction of the scrapers 22 and the length direction of the cross beam, in this embodiment, the first preset angle is 30 °, however, the first preset angle may be other angles, and in this embodiment, only 30 ° is taken as an example, and is not limited specifically. As shown in fig. 2, that is, the scrapers 22 are obliquely arranged, in the photovoltaic module array, the gaps between the adjacent photovoltaic panels 4 are not completely the same, which indicates that the scrapers 22 are located at different positions on the photovoltaic module array during movement, when the scrapers 22 are obliquely arranged, the length of the scrapers 22 in the moving direction of the cross beam is greater than the distance between any two photovoltaic panels, and when the scrapers 22 pass through the gaps, a part of the scrapers 22 is always located outside the gaps, and cannot fall into the gaps, so that the stagnation of the movement of the scraper assemblies 2 is avoided, and the continuous movement of the scraper assemblies 2 on the photovoltaic panels 4 can be ensured. Six parallel scrapers 22 are arranged on the beam 21 to clean the two rows of photovoltaic panels 4, but of course, the number of the scrapers 22 may be other, and may be adjusted according to the number of each row of photovoltaic panels 4.
It is noted that, as shown in fig. 2, each photovoltaic panel 4 in the assembly of photovoltaic panels 4 may also suffer from straightness issues, i.e. where two adjacent photovoltaic panels 4 are not flush, the photovoltaic panels 4 include: photovoltaic panel body 41 for power generation, frame 42 that encircles photovoltaic panel body 41, with reference to fig. 3, the thickness of frame 42 is higher than photovoltaic panel body 41, and is upwards protruding, and frame 42 includes: perpendicular to two horizontal strake 421 of crossbeam 21, parallel with two straight strakes of crossbeam, when two photovoltaic panel 4 are not parallel and level, two corresponding horizontal strakes 421 of photovoltaic panel 4 are not on same straight line, scraper 22 is from a photovoltaic to when removing on another photovoltaic board, because the problem of straightness accuracy can collide with horizontal strake 421, scraper 22 is flexible, the position that offsets with horizontal strake 421 can be lifted up by horizontal strake 421, because scraper 22 length is longer, the crooked radian in position that lifts up is great, make photovoltaic board body 41 form clean dead angle near horizontal strake 421, scraper 22 can't clean the dead angle, clean effect is relatively poor.
In this embodiment, the cleaning of the row of photovoltaic panels 4 is achieved by three scrapers 22, the three scrapers 22 are arranged on the beam 21, wherein the scraper 22 located in the middle does not touch the horizontal frame 42, and the scrapers 22 located at the two ends respectively abut against the two horizontal frames 421.

No dead angle for cleaning is left, and the cleaning quality is improved.
As shown in fig. 4 and 5, the main body portion 221 includes: a blade used for abutting against the photovoltaic panel body 41, and a fixed end 5 used for installing the blade on the beam 21.
It is worth noting that each photovoltaic panel 4 in the photovoltaic panel 4 array can also have the problem of flatness, the height of each photovoltaic panel 4 is not completely the same, when cleaning one photovoltaic panel 4, the blade abuts against the photovoltaic panel 4 and cleans the photovoltaic panel 4 when moving, when cleaning another photovoltaic panel 4 with different height, the blade can bend and abut against the photovoltaic panel 4, because the heights of the two photovoltaic panels 4 are different, the positions where the blade abuts against the photovoltaic panel 4 twice are different, the side cleaning capability of the blade is weaker, and the cleaning effect of the photovoltaic panels 4 with different heights cannot be guaranteed to ensure higher quality.
The blade includes: blade body and the arch 6 of establishing on the blade body, the blade body includes: a blade edge side facing the mounting side of the beam 21, a first side and a second side opposite to each other in the moving direction of the beam 21; the projections 6 are provided on the first and second sides and the nose side, respectively. Because the height of each photovoltaic board body 41 is different, the blade needs to be abutted against the photovoltaic board body 41 through the blade tip or the first side or the second side and cleans the photovoltaic board body 41 through the protrusion 6, and the protrusion 6 can ensure that the cleaning effect of the photovoltaic panels 4 with different heights ensures higher quality.
The bulge 6 arranged on the tool nose is square; the protrusions 6 arranged on the first side and the second side are strip-shaped protrusions 61, the strip-shaped protrusions 61 are arranged in a plurality of numbers and are symmetrically arranged on the first side and the second side respectively, the strip-shaped protrusions 61 are arranged along the direction opposite to the tool tip side of the installation side, and when the tool body abuts against the photovoltaic panel body 41 through the protrusions 6 at the tool tip part, the photovoltaic panel body 41 is cleaned through the protrusions 6 at the tool tip part; when the blade body is bent to abut against the photovoltaic panel body 41, at least one strip-shaped protrusion 61 abuts against the photovoltaic panel body 41, and the photovoltaic panel body 41 is cleaned when the cross beam 21 moves. As shown in fig. 5, the blade body takes place the bending of different degrees when offsetting with the photovoltaic board body 41 of co-altitude, the cross-section of strip arch 61 is triangle-shaped, triangle-shaped includes base and the protruding 6 angle relative with the base, the base is established on the first side or the second side of blade body, strip arch 61 offsets with photovoltaic board body 41 through protruding 6 angles, offset and the reciprocal motion cleans photovoltaic board body 41 through the line face, clean effect is better, many strip arch 61 can guarantee to have strip arch 61 to offset with photovoltaic board body 41 all the time, can clean photovoltaic board body 41, and clean effect all guarantees higher quality.
