The professional terms used in the present application are only for the purpose of describing the specific embodiments and are not intended to limit the protection scope of the present application.

[0037] As shown in Figure 1 and Figure 4 The present application provides a photovoltaic cleaning robot, which comprises a base frame 1 and a support wheel set.

[0038] The support wheel set comprises a plurality of first support wheels 2, each of which is rollably connected to the base frame 1. Specifically, the first support wheel 2 comprises a cylindrical portion 21 and a conical portion 22, and the conical portion 22 is arranged at one end of the cylindrical portion 21. When the photovoltaic cleaning robot of the present application is placed on a photovoltaic panel, the cylindrical portion 21 of the first support wheel 2 first contacts the panel glass. Under the action of gravity, the photovoltaic cleaning robot slides down along the photovoltaic panel. When the first support wheel 2 slides down to the frame on the photovoltaic panel, under the guidance of the conical portion 22, the first support wheel 2 can easily overcome the obstacles such as the frame protrusion, so as to facilitate the photovoltaic cleaning robot to continue to slide down until the photovoltaic cleaning robot contacts the upper edge of the photovoltaic panel; at the same time, it can also avoid the first support wheel 2 of the photovoltaic cleaning robot from knocking against the frame of the photovoltaic panel when it is placed, thereby reducing the potential damage to the photovoltaic panel and its frame structure.

[0039] As shown in Figure 2 and Figure 3 In an embodiment of the present application, the support wheel set further comprises a second support wheel 3 and a support wheel frame 4. The second support wheel 3 is rotatably connected to the support wheel frame 4, and the rotation axis of the second support wheel 3 is not parallel to the photovoltaic panel, but is arranged at an angle with the photovoltaic panel, and the wheel surface of the second support wheel 3 is used to abut against the upper edge of the photovoltaic panel. Compared with the first support wheel 2, the second support wheel 3 is the uppermost support wheel in the support wheel set. When the photovoltaic cleaning robot is placed, the second support wheel 3 is the last support wheel in the support wheel set to contact the photovoltaic panel, therefore, the second support wheel 3 does not need a cylindrical portion parallel to the photovoltaic panel, but is arranged at an angle with the photovoltaic panel, and the whole plays a guiding role of the conical portion.

[0040] As shown in Figure 1 and Figure 2As shown in the drawings, in one embodiment of the present application, the base frame 1 comprises a main beam 11 and a plurality of support beams 12. The main beam 11 serves as the backbone of the entire frame, and bears the main load and connection function, providing a solid support foundation for the entire photovoltaic cleaning robot. The support beams 12 are spaced apart from each other and connected to the main beam 11, and the support beams 12 and the main beam 11 are arranged perpendicular to each other, not only enhancing the overall stability of the frame, but also effectively dispersing the load and improving the load-carrying capacity of the structure. The support wheel set is arranged on the main beam 11.

[0041] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in one embodiment of the present application, the first support wheels 2 are arranged spaced apart from each other along the extension direction of the main beam 11. This avoids mutual interference between the first support wheels 2, improves the overall motion fluency and stability of the robot, and also makes the load distribution of the robot more balanced, ensuring that the robot can maintain a stable posture in different working states, thereby improving the accuracy and efficiency of the cleaning operation.

[0042] As shown in the drawings, Figure 2 As shown in the drawings, in one embodiment of the present application, the walking wheel assembly 5 is arranged at one end of the main beam 11, and the walking wheel assembly 5 is used to contact the upper edge of the photovoltaic panel. The walking wheel assembly 5 is a functional component for driving the photovoltaic cleaning robot to walk on the photovoltaic panel. The walking wheel assembly 5 contacts the upper edge of the photovoltaic panel, which not only prevents the photovoltaic cleaning robot from continuing to slide down, but also uses the weight of the photovoltaic cleaning robot to press the walking wheel assembly 5 against the upper edge of the photovoltaic panel, thereby avoiding the walking wheel assembly 5 from slipping on the upper edge of the photovoltaic panel, and ensuring the driving stability of the walking wheel assembly 5.

[0043] As shown in the drawings, Figure 2 As shown in the drawings, in one embodiment of the present application, the walking wheel assembly 5 comprises a wheel seat 51 and a walking wheel 52. The wheel seat 51 is mounted at one end of the main beam 11, and the walking wheel 52 is rotatably connected to the wheel seat 51. The walking wheel 52 contacts the upper edge of the photovoltaic panel, and the rotation axis of the walking wheel 52 is perpendicular to the photovoltaic panel, so as to facilitate full contact between the walking wheel 52 and the upper edge of the photovoltaic panel, and ensure sufficient contact area between the walking wheel 52 and the photovoltaic panel.

[0044] As shown in the drawings, Figure 1 and Figure 2As shown in the drawings, in one embodiment of the present application, the photovoltaic cleaning robot of the present application further comprises a cleaning roller 6. The cleaning roller 6 is arranged in parallel with the main beam 11, one end of the cleaning roller 6 is connected to one support beam 12, and the other end of the cleaning roller 6 is connected to an adjacent support beam 12. The cleaning path of the cleaning roller 6 is consistent with the extension direction of the photovoltaic panel. The material, hardness and surface texture of the cleaning roller 6 are carefully selected and optimized to ensure that it can generate sufficient friction to remove dust and dirt on the surface when it is in contact with the photovoltaic panel, while avoiding any form of damage to the photovoltaic panel. In addition, the rotation speed and direction of the cleaning roller 6 can also be adjusted according to the specific work requirements to achieve the best cleaning effect.

[0045] As Figure 1 shown in the drawings, in one embodiment of the present application, the cleaning roller 6 is arranged in pairs, one of the pair of cleaning rollers 6 is located on one side of the main beam 11, and the other of the pair of cleaning rollers 6 is located on the other side of the main beam 11. When working, in the direction of travel of the photovoltaic cleaning robot, the pair of cleaning rollers 6 sequentially clean the photovoltaic panel in order, and the superposition effect of the two cleaning processes further improves the cleaning effect.

[0046] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
