[0049] Example

[0050] Reference Figure 1 As shown, this embodiment provides a photovoltaic cleaning robot with dust and snow removal functions, comprising a frame 1, a travel system, a dust removal component, and a snow removal component. The frame 1 comprises two main beams 11 and two end beams 12, with the two main beams 11 connected to the two end beams 12, respectively. Since photovoltaic panels are generally large, the main beams 11 are generally long. In this embodiment, a crossbeam 13 is connected between the two main beams 11 to ensure the reliability of the frame 1. In other embodiments, the number of crossbeams 13 can be adjusted according to the length of the main beams 11.

[0051] Specifically, the travel system is mounted on the frame 1 and is used to drive the frame 1 to move. By driving the frame 1 back and forth over the photovoltaic panels, comprehensive dust and snow removal operations are achieved. The travel system includes a second drive member and a travel wheel 2. The travel wheel 2 is mounted on the end beam 12 or the cross beam 13. The second drive member is connected to the travel wheel 2. The second drive member drives the travel wheel 2 to move, thereby driving the cleaning robot as a whole to move in a direction perpendicular to the length of the main beam 11.

[0052] Specifically, the dust removal assembly includes a roller brush 3, which is rotatably mounted in the frame 1. One end of the roller brush 3 is rotatably connected to an end beam 12, and the other end is connected to a first drive member, which is mounted on the other end beam 12 and drives the roller brush 3 to rotate. In this embodiment, the roller brush 3 and the travel wheel 2 are respectively driven by separate drive elements. During operation, the roller brush 3 can be driven to rotate in the same direction as the travel wheel 2, or in the opposite direction. When the roller brush 3 rotates in the same direction as the travel wheel 2, it can provide auxiliary thrust for the movement of the cleaning robot; when the roller brush 3 rotates in the opposite direction to the travel wheel 2, it can improve the degree of cleaning.

[0053] Specifically, the snow removal assembly includes a snow removal shaft 4, a snow pusher 5, and an angle adjustment member. The snow removal shaft 4 is rotatably mounted on the frame 1; the snow pusher 5 is connected to the snow removal shaft 4 and is located on the side of the roller brush 3 in the direction of movement; the angle adjustment member is mounted on the frame 1 and connected to the snow removal shaft 4, driving the snow pusher 5 to change its angle. The angle adjustment member is specifically mounted within the end beam 12. The angle adjustment member adjusts the angle of the snow pusher 5. When the snow pusher 5 is at a specific angle, such as a vertically downward position, the snow pusher 5 is inserted into and contacts the accumulated snow, causing the cleaning robot to push the accumulated snow and cause it to fall during movement. When the snow pusher 5 is at another specific angle, such as a vertically upward position, the snow pusher 5 reduces its obstruction to the movement of the cleaning robot, preventing the snow pusher 5 from blocking dust raised by the roller brush 3.

[0054] The photovoltaic cleaning robot with dust and snow removal functions provided in this embodiment adjusts the angle of the snow pusher 5 through an angle adjustment part, so that the snow pusher 5 is at a certain specific angle, for example, when it is in a vertical downward state, it enters the snow removal mode, and when the snow pusher 5 is at another specific angle, for example, when it is in a vertical upward state, it enters the dust removal mode. It can switch between the dust removal and snow removal modes to meet the dust removal and snow removal requirements of the photovoltaic panels.

[0055] Specifically, in this embodiment, two forms of angle adjustment members are provided, one of which is referred to as Figure 2-6 As shown, another angle adjustment member is shown in FIG. Figure 7-8 shown.

[0056] It should be noted that, in this embodiment, the snow pusher 5 can be installed on one side or on both sides, that is, the snow pusher 5 is provided on only one side of the roller brush 3, or the snow pushers 5 are provided on both sides of the roller brush 3. In the following embodiments, the snow pushers 5 are provided on both sides for illustration.

[0057] The first angle adjustment member, refer to Figure 2 As shown, the angle adjustment member includes a telescopic push rod 61 and a transmission assembly. The transmission assembly comprises two sets of snow-pushing shafts, one for each side of the snow-pushing blade 5. The transmission assembly includes a rocker 62, a driving sprocket, a driven sprocket, and a chain 65. One end of the rocker 62 is rotatably mounted on the end of the frame 1, and the other end is hingedly connected to the telescopic push rod 61. Specifically, the ends of the telescopic push rod 61 are hingedly connected to the rockers 62 of the two transmission assemblies. The telescopic push rod 61 retracts and drives the two rockers 62 to rotate in opposite directions. The rotating sprocket is connected to the rocker 62 and rotates with it. The driven sprocket is connected to the snow-plowing shaft 4, driving the rotation of the snow-plowing shaft 4. The chain 65 is connected to the driving sprocket and the driven sprocket, respectively. Rotation of the rocker 62 drives the driving sprocket, which in turn drives the driven sprocket, ultimately rotating the snow-plowing shaft 4 and changing the angle of the snow-pushing blade 5.

[0058] Specifically, in this embodiment, the telescopic push rod 61 can be a one-way electric push rod, so that the telescopic push rod 61 is in a floating state, that is, the telescopic push rod 61 does not need to be connected to the frame 1. That is, the one-way extension of the telescopic push rod 61 can push the two rocking arms 62 to rotate.

[0059] Specifically, refer to Figure 5 and Figure 7 As shown, the transmission assembly also includes a mounting base 68, which is mounted on the end beam 12 and located at the end of the frame 1. The driving sprocket includes a driving shaft 66 and a driving sprocket body 63. The driving shaft 66 is rotatably connected to the mounting base 68 via a copper sleeve 681. The driving sprocket body 63 is connected to the driving shaft 66. The rocker 62 is also connected to the driving shaft 66. That is, the rocker 62 is rotatably mounted to the end of the frame 1 via the driving shaft 66 and the mounting base 68. The driven sprocket includes a driven shaft 67 and a driven sprocket body 64. The driven shaft 67 passes through the mounting base 68 and is rotatably connected to a first bearing seat 687 via a first bearing 686. The first bearing seat 687 is connected to the end beam 12. The driven shaft 67 is connected to the snow removal shaft 4, and the driven sprocket body 64 is connected to the driven shaft 67. Therefore, the driven shaft 67 is driven by the driven sprocket body 64, thereby driving the snow removal shaft 4.

[0060] Specifically, refer to Figure 6As shown, the driving sprocket is provided with a limit screw 682 that moves as the driving sprocket rotates. A first adjustment screw 683 and a second adjustment screw 684 are provided at the ends of the frame 1. The first and second adjustment screws 683 and 684 are respectively used to prevent the limit screw 682 from moving. The mounting base 68 is provided with an arcuate slot 685 that corresponds to the movement of the limit screw 682. The first and second adjustment screws 683 and 684 are respectively provided at the ends of the arcuate slot 685. When the limit screw 682 moves to abut against the first or second adjustment screw 683 or 684, further movement of the limit screw 682 is restricted, thereby restricting further rotation of the snow pusher 5. Therefore, when the limit screw 682 moves to abut against the first or second adjustment screw 683 or 684, the snow pusher 5 rotates to a vertically upward or vertically downward position.

[0061] By adopting the first angle adjustment member, a telescopic push rod 61 can be used to drive the snow pushers 5 on both sides to adjust the angle, which has low cost, light weight and easy control.

[0062] The second angle adjustment part, refer to Figure 7-8 The angle adjustment member includes a motor 601 , which is mounted on the frame 1 , and an output shaft 605 of the motor 601 is connected to the snow removal shaft 4 .

[0063] Specifically, the motor 601 is mounted on the end beam 12 via an adapter plate 602. A second bearing seat 604 is also mounted on the end beam 12. The output shaft 605 of the motor 601 passes through the end beam 12 and is connected to the second bearing seat 604 via a second bearing 603. A dust cover 606 and a retaining spring 607 are also provided on the end of the bearing seat away from the end beam 12. The output shaft 605 of the motor 601 passes through the dust cover 606 and is connected to the snow removal shaft 4.

[0064] The second angle adjustment member can be used to control the snow pushers 5 on both sides separately, but the cost is higher than that of the first method.

[0065] Specifically, refer to Figure 9 The snow removal shaft 4 includes a plurality of sub-shafts 41 arranged along its length direction; Figure 10 As shown, adjacent sub-rotating shafts 41 are respectively connected to adapter shafts 42; the adapter shafts 42 are rotatably connected to the support base 14, and the support base 14 is connected to the frame 1. By providing the support base 14 between adjacent sub-rotating shafts 41, the support base 14 supports the snow removal shaft 4, thereby preventing deformation of the snow removal shaft 4 during snow removal due to its relatively long length and improving the overall rigidity of the snow removal shaft 4.

[0066] Specifically, the snow pusher 5 includes a plurality of flexible plates 52. A pressure strip 51 is provided on the sub-rotating shaft 41. The flexible plates 52 are located between the sub-rotating shaft 41 and the pressure strip 51. The pressure strip 51 is connected to the sub-rotating shaft 41 and clamps the flexible plates 52. Using a flexible material as the snow pusher 5 avoids damage to the surface of the photovoltaic panel.

[0067] Working process: refer to Figure 11 As shown, the photovoltaic panels are generally in an inclined state, and the cleaning robot is placed on the photovoltaic panels so that it tilts along with the photovoltaic panels.

[0068] When snow removal is required, the snow pusher 5 is driven to rotate vertically downward by the angle adjustment member. Figure 12 As shown, the robot is driven by the travel system, pushing the accumulated snow, causing it to slide down the slope of the photovoltaic panels or fall into the gaps in the photovoltaic panel bridge. Depending on the needs of the operation, the drive roller brush 3 can be rotated in the same direction as the travel wheel 2 to provide auxiliary thrust for the robot, or the drive roller brush 3 can be rotated in the opposite direction to the travel wheel 2 to clean the photovoltaic panels more thoroughly.

[0069] When dust removal is required, the snow pusher 5 is driven to rotate vertically upwards by the angle adjustment member. Figure 13 As shown, the walking system drives the cleaning robot to move and at the same time drives the roller brush 3 to rotate to clean the inside of the photovoltaic panel.

[0070] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
