It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series or parallel to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0050] In order to be able to assemble a cleaning device of matching size according to the actual area size or shape of the photovoltaic panel, thereby improving the applicability of the cleaning device when used, a cleaning device for a photovoltaic panel is proposed in an embodiment of the present application. Figure 1 FIG. 1 is a schematic diagram of the structure of a cleaning device for a photovoltaic panel in an embodiment of the utility model. Figure 1 As shown, the cleaning device for photovoltaic panels may include: a first track assembly 1 having a first track 12 , a second track assembly 2 having a second track, a cleaning assembly 3 , a first drive assembly 4 and a second drive assembly 9 .

[0051] The first track assembly 1 may include a plurality of first sub-track members 11. A plurality of first sub-track members 11 are spliced ​​to form the first track assembly 1. According to the length of the first track assembly 1, a suitable number of first sub-track members 11 may be selected to form the first track assembly 1 by splicing, so that the length of the first track assembly 1 can be arbitrarily changed according to the size of the photovoltaic panel, for example, the width of the photovoltaic panel. Similarly, the second track assembly 2 may include a plurality of second sub-track members 21. A plurality of second sub-track members 21 are spliced ​​to form the second track assembly 2. According to the length of the second track assembly 2, a suitable number of second sub-track members 21 may be selected to form the second track assembly 2 by splicing, so that the length of the second track assembly 2 can be arbitrarily changed according to the size of the photovoltaic panel.

[0052] The cleaning assembly 3 is used to clean the photovoltaic panel. For example, the cleaning assembly 3 has a cleaning brush, and the photovoltaic panel is cleaned by the cleaning brush. The cleaning assembly 3 may include a plurality of sub-cleaning parts 31, and the plurality of sub-cleaning parts 31 are spliced ​​to form the cleaning assembly 3. In this way, the length of the cleaning assembly 3 can be arbitrarily changed according to the size of the photovoltaic panel, for example, the length of the photovoltaic panel.

[0053] The first driving assembly 4 is used to drive one end of the cleaning assembly 3 to move along the first track 12 of the first track assembly 1. The second driving assembly 9 is used to drive the other end of the cleaning assembly 3 to move along the first track 12 of the first track assembly 1. The first driving assembly 4 is installed on the first track assembly 1 and connected to one end of the cleaning assembly 3. The second driving assembly 9 is installed on the second track assembly 2 and connected to the other end of the cleaning assembly 3. The first driving assembly 4 can move on the first track 12, and the second driving assembly 9 can move on the second track, thereby driving the cleaning assembly 3 to move to clean different positions of the photovoltaic panel.

[0054] The first track assembly 1 and the second track assembly 2 in the present application can be respectively arranged on both sides of the photovoltaic power generation panel to be cleaned. Since the first track assembly 1 is formed by splicing a plurality of first sub-track members 11, and the second track assembly 2 is formed by splicing a plurality of second sub-track members 21, the number of the second sub-track members 21 can be arbitrarily changed according to the size of the photovoltaic power generation panel, thereby changing the length of the second track assembly 2, so that the length of the second track assembly 2 is adapted to photovoltaic power generation panels of different sizes; similarly, since the cleaning assembly 3 is formed by splicing a plurality of sub-cleaning members 31, the number of the sub-cleaning members 31 can be arbitrarily changed according to the size of the photovoltaic power generation panel, thereby changing the length of the cleaning assembly 3, so that the length of the cleaning assembly 3 is adapted to photovoltaic power generation panels of different sizes. Afterwards, the first drive assembly 4 installed on the first track assembly 1 and the second drive assembly 9 installed on the second track assembly 2 are used to drive the two ends of the cleaning assembly 3 to move to clean different positions of the photovoltaic power generation panel. By means of the above method, the cleaning device for photovoltaic panels can be assembled into a cleaning device of matching size according to the actual size of the photovoltaic panels, thereby improving the applicability of the cleaning device when in use; in addition, when the cleaning device is not in use, it can be disassembled for easy storage and transportation.

[0055] As a feasible method, two adjacent first sub-rail members 11 are connected by a first splicing assembly to form the first rail assembly 1 in a splicing manner. Figure 4 Schematic diagram of the structure of the joint of the sub-track parts in the embodiment of the utility model, as shown in Figure 4As shown, the first splicing assembly may include: a first slot component 141 and a first limiting mechanism 142 connected to the end of one of the first sub-track components 11; a first plug-in component 143 and a first positioning component 144 connected to the end of another of the first sub-track components 11. The first slot component 141 and one of the first sub-track components 11 form a first slot 1411, and the first plug-in component 143 can be inserted into the first slot 1411. Further, in order to prevent the two adjacent first sub-track components 11 from being easily separated, the first positioning component 144 and the first limiting mechanism 142 can have two states. When the two first sub-track components 11 are spliced ​​together, the first limiting mechanism 142 is in the first position so that the first positioning component 144 and the first limiting mechanism 142 are locked in a buckled state, and at this time, the two adjacent first sub-track components 11 cannot be separated. When the two first sub-track components 11 need to be separated, the first limiting mechanism 142 is in the second position so that the first positioning component 144 and the first limiting mechanism 142 are in a separable state. Whether the first limiting mechanism 142 is in the first position or the second position can be achieved by manually operating the first limiting mechanism 142 .

[0056] In a specific embodiment, Figure 4 As shown, the first limiting mechanism 142 may include: a first support 1421, a first rod 1422 disposed on the first support 1421, a first torsion spring 1423 sleeved on the first rod 1422, and a first limiting plate 1424. When the two first sub-track members 11 are spliced ​​together, the first limiting plate 1424 and the first positioning member 144 are buckled and kept in a locked state, and the first torsion spring 1423 can make the first limiting plate 1424 and the first positioning member 144 buckled and kept in a locked state. For example, the ends of the first limiting plate 1424 and the first positioning member 144 opposite to each other are V-shaped, so that the two are buckled, and the two cannot move in a direction away from each other, and thus the first positioning member 144 cannot be separated from the first limiting mechanism 142. When the two first sub-track members 11 need to be separated, the first limiting mechanism 142 needs to be operated to be in the second position, that is, the other end of the first limiting plate 1424 is pressed, so that the first torsion spring 1423 rotates, and the end of the first limiting plate 1424 that is engaged with the first positioning member 144 rotates, thereby separating from the first positioning member 144, and the engaged state is released. At this time, the first positioning member 144 and the first limiting mechanism 142 are in a separable state.

[0057] Similarly, two adjacent second sub-rail components 21 are spliced ​​together to form a second rail component 2 through a second splicing component. The second splicing component includes: a second slot component and a second limiting mechanism connected to the end of one of the second sub-rail components 21; a second plug-in component and a second positioning component connected to the end of another second sub-rail component 21. The second slot component and one of the second sub-rail components 21 form a second slot, and the second plug-in component can be inserted into the second slot. The second positioning component and the second limiting mechanism can have two states. When the two second sub-rail components 21 are spliced ​​together, the second limiting mechanism is in the first position so that the second positioning component and the second limiting mechanism are buckled and locked; when the two second sub-rail components 21 need to be separated, the second limiting mechanism is in the second position so that the second positioning component and the second limiting mechanism are in a separable state.

[0058] In a specific embodiment, the second limiting mechanism includes: a second support, a second rod body arranged on the second support, a second torsion spring sleeved on the second rod body and a second limiting plate, and the second torsion spring can make the second limiting plate and the second positioning member buckle and maintain a locked state.

[0059] As feasible, Figure 1 As shown, the plurality of first sub-rail members 11 include a first head rail member 111, at least one first middle rail member 112 and a first tail rail member 113. The first head rail member 111 is connected to a first middle rail member 112 by splicing, and the first tail rail member 113 is connected to a first middle rail member 112 by splicing. When there are multiple first middle rail members 112, the multiple first middle rail members 112 are sequentially connected by splicing. One end of the first head rail member 111 does not need to be spliced ​​again, so it can be disconnected from the first splicing assembly. One end of the first head rail member 111 can have a blocking portion to limit the moving range of the first drive assembly 4 to prevent it from being separated from the first head rail member 111. One end of the first tail rail member 113 does not need to be spliced ​​again, so it can be disconnected from the first splicing assembly. One end of the first tail rail member 113 can have a blocking portion to limit the moving range of the first drive assembly 4 to prevent it from being separated from the first head rail member 111.

[0060] Similarly, if Figure 1As shown, the plurality of second sub-rail members 21 include a second head rail member 211, at least one second middle rail member 212 and a second tail rail member 213. The second head rail member 211 is connected to a second middle rail member 212 by splicing, and the second tail rail member 213 is connected to a second middle rail member 212 by splicing. When there are multiple second middle rail members 212, the multiple second middle rail members 212 are sequentially connected by splicing. One end of the second head rail member 211 does not need to be spliced ​​again, so it can be disconnected from the second splicing assembly. One end of the second head rail member 211 can have a blocking portion to limit the moving range of the second drive assembly 9 to prevent it from being separated from the second head rail member 211. One end of the second tail rail member 213 does not need to be spliced ​​again, so it can be disconnected from the second splicing assembly. One end of the second tail rail member 213 can have a blocking portion to limit the moving range of the second drive assembly 9 to prevent it from being separated from the second head rail member 211.

[0061] As feasible, Figure 1 Shown, a plurality of sub-cleaning parts 31 can comprise a left cleaning part 311, at least one middle cleaning part 312, a right cleaning part 313.The first drive assembly 4 is connected with the left cleaning part 311, the second drive assembly 9 is connected with the right cleaning part 313, a side of at least one middle cleaning part 312 is connected with the left cleaning part 311 by splicing mode, and the other side of at least one middle cleaning part 312 is connected with the right cleaning part 313 by splicing mode.When the middle cleaning part 312 is a plurality of, a plurality of middle cleaning parts 312 are connected successively by splicing mode.

[0062] In a feasible embodiment, the splicing mode between the plurality of cleaning sub-pieces 31 is to adopt a plug-in structure for splicing. This structure is easy to process and splice, and the firmness after splicing is also strong.

[0063] Specifically, Figure 2 for Figure 1 The enlarged view of point A in the middle is as follows: Figure 2 As shown, one of the two adjacent sub-cleaning parts 31 has a docking groove 32, and the other has a docking protrusion 33, and the docking protrusion 33 can be inserted into the docking groove 32 to realize the splicing of the two sub-cleaning parts 31 using a plug-in structure. The number of the docking grooves 32 and the docking protrusions 33 corresponds, generally multiple, so as to ensure the firmness after splicing and the stability of the cleaning assembly 3 as a whole.

[0064] As feasible, Figure 3 FIG. 1 is a schematic diagram of a structure in which a driving assembly is installed on a first track assembly in an embodiment of the utility model. Figure 3As shown, the first track 12 has a T-shaped first slide groove; the first drive assembly 4 has a T-shaped first structure 41 installed in cooperation with the first slide groove. The above method can make the first drive assembly 4 not easy to be separated from the first track 12, and can ensure that the first drive assembly 4 slides along the first track 12. Similarly, the second track has a T-shaped second slide groove; the second drive assembly 9 has a T-shaped second structure installed in cooperation with the second slide groove.

[0065] In order to enable the first drive assembly 4 to actively move back and forth on the first track assembly 1, it is feasible to Figure 3 As shown, the first track assembly 1 includes a first rack portion 13; the first drive assembly 4 includes a first drive motor 42 connected to a first gear 43, and the first gear 43 is meshed with the first rack portion 13. The first drive motor 42 rotates to drive the first gear 43 to rotate, so that the first drive assembly 4 and the first track assembly 1 are relatively moved. Similarly, the second track assembly 2 includes a second rack portion; the second drive assembly 9 includes a second drive motor connected to a second gear, and the second gear is meshed with the second rack portion.

[0066] As feasible, the cleaning device for photovoltaic panels may include: a first support leg 5 and a second support leg 6 connected to the first track assembly 1, the support legs can make the first track assembly 1 have a required height so that the first track assembly 1 is slightly higher than the height of the photovoltaic panel. Since the photovoltaic panel is in an inclined state, the length of the first support leg 5 needs to be greater than the length of the second support leg 6. The cleaning device for photovoltaic panels may also include: a third support leg 7 and a fourth support leg 8 connected to the second track assembly 2, the support legs can make the second track assembly 2 have a required height so that the second track assembly 2 is slightly higher than the height of the photovoltaic panel. Since the photovoltaic panel is in an inclined state, the length of the third support leg 7 needs to be greater than the length of the fourth support leg 8. The length of the first support leg 5 can be equal to the length of the third support leg 7, and the length of the second support leg 6 can be equal to the length of the fourth support leg 8, so that the inclination of the first track assembly 1 and the second track assembly 2 is consistent. Further, the inclination of the first track assembly 1 and the second track assembly 2 can be consistent with the inclination of the photovoltaic panel, so as to ensure that the cleaning assembly 3 has the same degree of cleaning at different positions of the photovoltaic panel during the movement.
