[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] In order to be able to walk on the photovoltaic array and perform cleaning work, and improve the power generation efficiency of the photovoltaic array, this embodiment provides a walking mechanism and a photovoltaic cleaning device. Figures 1 to 6 The specific contents of this embodiment are described in detail.

[0045] This embodiment provides a walking mechanism, which includes at least two walking units 100, each of which includes a mobile frame 1, a floating adapter assembly 2, and a drive wheel assembly 3. The mobile frames 1 of two adjacent walking units 100 are hinged to each other, the first end of the floating adapter assembly 2 is connected to the mobile frame 1, and the drive wheel assembly 3 includes a first rotating shaft 31, a flip plate 32, and a second rotating shaft 34 with a roller 33. One end of the first rotating shaft 31 is rotatably connected to the second end of the floating adapter assembly 2, and the other end of the first rotating shaft 31 is fixedly connected to the flip plate 32. At least three second rotating shafts 34 are circumferentially spaced and rotatably arranged on the flip plate 32.

[0046] In short, the walking mechanism provided by the present invention hinges the mobile frames 1 of the two walking units 100 to each other, so as to facilitate and safely cross the gap between the two photovoltaic modules 003. The driving wheel group 3 is installed on the mobile frame 1 through the floating adapter assembly 2. When the driving wheel group 3 crosses an obstacle, the driving wheel group 3 floats up and down. When there is no obstacle and the walking mechanism is in the first working state, the three second rotating shafts 34 drive the three rollers 33 to rotate, so as to realize the movement of the walking mechanism on the photovoltaic module 003. When encountering an obstacle, the walking mechanism is in the second working state, and the first rotating shaft 31 drives the flip plate 32 and the rollers 33 on the flip plate 32 to revolve, so that the rollers 33 can cross the obstacle, thereby improving the obstacle-crossing ability of the walking mechanism and ensuring the smoothness of the movement of the walking mechanism. The roller brush assembly is installed on the walking mechanism, so that the roller brush assembly can clean the photovoltaic module 003 and improve the power generation efficiency of the photovoltaic array.

[0047] Furthermore, the circumferential wall of the roller 33 is provided with an annular groove 331. The steel strand 002 is positioned in the annular groove 331, ensuring that the roller 33 moves along the steel strand 002.

[0048] Specifically, the floating adapter assembly 2 includes a first mounting plate 21, a guide post 22, an elastic member 23, and a second mounting plate 24. The first mounting plate 21 is mounted on the mobile frame 1 and is provided with a guide sleeve. One end of the guide post 22 is connected to the second mounting plate 24, and the other end of the guide post 22 slides through the guide sleeve. The elastic member 23 is sleeved on the guide post 22 and located between the first mounting plate 21 and the second mounting plate 24. During movement, if an obstacle or a drop is encountered, the guide post 22, the second mounting plate 24, and the drive wheel assembly 3 float upward along the extension direction of the guide sleeve.

[0049] Exemplarily, at least two guide posts 22 and elastic members 23 are provided. By increasing the number of guide posts 22 and elastic members 23, it is convenient to balance the force on the left and right sides of the second mounting plate 24.

[0050] Optionally, the floating adapter assembly 2 further includes a limiting rod 25, to which the portions of the two guide posts 22 extending beyond the first mounting plate 21 are fixedly connected. When the roller 33 floats downward without contacting an object, the additional limiting rod 25 prevents the guide posts 22 from slipping out of the guide sleeve.

[0051] Furthermore, the traveling mechanism further includes a rotary power unit 4, which is disposed on the second mounting plate 24. The first rotating shaft 31 and at least three second rotating shafts 34 are all in transmission connection with the rotary power unit 4. For example, the rotary power unit 4 can be, but is not limited to, a motor.

[0052] Furthermore, the walking unit 100 further includes a support frame 5, and support frames 5 are provided at opposite ends of the mobile frame 1. By adding the support frames 5, not only the overall structural strength of the mobile frame 1 can be improved, but also the support frames 5 can be used for decoration and for mounting other parts.

[0053] Furthermore, a correction assembly 6 is provided on the outer wall of the support frame 5. The correction assembly 6 includes a cantilever rod 61, a fixed shaft 62, a torsion spring 63, a first swinging rod 65 with a first correction wheel 64, and a second swinging rod 67 with a second correction wheel 66. The cantilever rod 61 is connected to the outer wall of the support frame 5. The fixed shaft 62 is fixedly provided at the lower end of the cantilever rod 61. One end of the first and second swinging rods 65 and 67 are both rotatably connected to the fixed shaft 62. The spiral section of the torsion spring 63 is sleeved on the fixed shaft 62. The first connecting section of the torsion spring 63 is connected to the first swinging rod 65, and the second connecting section of the torsion spring 63 is connected to the second swinging rod 67. Under the action of the torsion spring 63, the first correction wheel 64 of the first swinging rod 65 and the second correction wheel 66 of the second swinging rod 67 always have a tendency to roll along the side of the photovoltaic module 003, thereby guiding the walking unit 100 from one photovoltaic module 003 to the next photovoltaic module 003 and preventing the walking unit 100 from deflecting during movement.

[0054] Furthermore, the outer wall surface of the support frame 5 is provided with an anti-slip assembly 7, which includes a support leg 71 and a first anti-slip wheel 72. The support leg 71 is fixedly connected to the support frame 5, and the first anti-slip wheel 72 is rotatably arranged at the bottom of the support leg 71, and / or a second anti-slip wheel 68 is provided on the fixed shaft 62. By adding the first anti-slip wheel 72 to the outer wall surface of each support frame 5, it is convenient to limit the position of the walking unit 100 in the upper and lower directions of the photovoltaic module 003. By adding the second anti-slip wheel 68, it is convenient to limit the position of the walking unit 100 on both sides of the photovoltaic module 003, thereby preventing the walking unit 100 from falling off the photovoltaic module 003.

[0055] This embodiment also provides a photovoltaic cleaning device, which includes a roller brush assembly and the above-mentioned walking mechanism. The roller brush assembly is arranged on the mobile frame 1, and the roller brush assembly is used to clean the photovoltaic assembly 003 to improve the power generation efficiency of the photovoltaic array.

Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention.
