[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] Please refer to the attached document. Figures 1-14 This application provides a photovoltaic cleaning robot 100, which is used to remove dust from the surface of photovoltaic panels. The photovoltaic cleaning robot 100 includes a robot body 10, a track assembly 20, a roller brush assembly 30, and a water spray assembly 40. The track assembly 20 is located on the left or right side of the robot body 10, the roller brush assembly 30 is located on the front or rear side of the robot body 10, and the water spray assembly 40 is located on the lower side of the robot body 10.

[0056] In this embodiment, the robot body 10 serves as a support component for the photovoltaic cleaning robot 100, and the robot body 10 is used to support the track assembly 20, the roller brush assembly 30, and the water spray assembly 40.

[0057] In this embodiment, the track assembly 20 is disposed on the left or right side of the robot body 10. The track assembly 20 is connected to the robot body 10 and moves relative to the photovoltaic panel to facilitate adjusting the position of the track assembly 20 relative to the photovoltaic panel. This allows the robot body 10 to move relative to the photovoltaic panel via the track assembly 20, thereby adjusting the overall position of the photovoltaic cleaning robot 100 and enabling movement of the photovoltaic panel to different positions.

[0058] At this time, the track assembly 20 includes a plurality of first track wheels 21 and a track 22; the plurality of first track wheels 21 are rotatably connected to the robot body 10 and arranged in a ring to facilitate adjustment of the position of the plurality of first track wheels 21 relative to the robot body 10; the track 22 is located on the outer periphery of the plurality of first track wheels 21 and is ring-fitted onto the plurality of first track wheels 21 to facilitate fixing the track 22 between the plurality of first track wheels 21, thereby facilitating the track 22 to roll as the plurality of first track wheels 21 rotate, so as to enable the track assembly 20 to travel relative to the photovoltaic panel.

[0059] The track 22 is provided with a first internal tooth portion 221 and a positioning portion 222. The positioning portion 222 is arranged adjacent to the first internal tooth portion 221. Multiple first track wheels 21 mesh with the first internal tooth portion 221 so that the track 22 can mesh with the multiple first track wheels 21 through the first internal tooth portion 221. This facilitates the track 22 to be fixed to the multiple first track wheels 21 by meshing, so that the track 22 can travel relative to the surface of the photovoltaic panel. The multiple first track wheels 21 are positioned and connected to the positioning portion 222 to limit the deviation of the track 22, so as to prevent the track 22 from deviating during travel. This ensures the meshing effect between the multiple first track wheels 21 and the first internal tooth portion 221 and improves the travel stability of the track assembly 20. Optionally, the first internal tooth portion 221 is an internal gear.

[0060] In addition, the positioning part 222 and the first internal tooth part 221 are arranged sequentially along the width direction of the track 22, and the positioning part 222 extends along the length direction of the track 22. The first track wheel 21 is provided with a first gear part 211 and a groove 21a. The first gear part 211 meshes with the first internal tooth part 221 so that the track 22 can be meshed with the first track wheel 21 through the first gear part 211 and the first internal tooth part 221. The groove 21a is for the positioning part 222 to pass through. The groove 21a is arranged around the first track wheel 21 so that the positioning part 222 can be positioned and connected with the first track wheel 21 through the groove 21a to limit the deviation of the track 22 and prevent the track 22 from deviating during travel. This ensures the meshing effect of multiple first track wheels 21 and the first internal tooth part 221 and improves the travel stability of the track assembly 20. Optionally, the first gear part 211 is an external gear.

[0061] In this embodiment, the groove 21a and the positioning part 222 are in clearance fit; or, the inner sidewall of the groove 21a can contact the sidewall of the positioning part 222, and the inner contour of the groove 21a is adapted to the outer contour of the positioning part 222, so that the positioning part 222 passes through the groove 21a, so that the positioning part 222 can be positioned and connected with the first track wheel 21 through the groove 21a, thereby limiting the deviation of the track 22, so that the track 22 can be prevented from deviating during driving, ensuring the meshing effect of the multiple first track wheels 21 and the first internal tooth part 221, and improving the driving stability of the track assembly 20.

[0062] There is a height difference between the surface of the positioning part 222 and the first internal tooth part 221, so that the top of the positioning part 222 is higher than the top of the first internal tooth part 221, thereby facilitating the positioning part 222 to pass through the groove 21a.

[0063] In this embodiment of the application, the first gear portion 211 has two, and a groove 21a is formed between the two first internal gear portions 221; the positioning portion 222 is located in the groove 21a; the positioning portion 222 is inserted into the groove 21a and is restricted by the inner sidewall of the groove 21a to limit the deviation of the positioning portion 222, thereby facilitating the restriction of the deviation of the track 22, and further facilitating the track 22 to prevent deviation during travel.

[0064] In this embodiment, the track assembly 20 includes a track wheel frame 23 and a plurality of second track wheels 24. The track wheel frame 23 is connected to the robot body 10 so that the track wheel frame 23 is fixed to the robot body 10. The plurality of second track wheels 24 are rotatably connected to the track wheel frame 23 so as to adjust the position of the plurality of second track wheels 24 relative to the track wheel frame 23. The plurality of second track wheels 24 engage with a first internal tooth portion 221 so that the plurality of second track wheels 24 are connected to the track 22 through the first internal tooth portion 221. This facilitates the increase of the rolling smoothness of the track 22 relative to the photovoltaic panel by arranging the plurality of second track wheels 24, thereby improving the driving smoothness of the track assembly 20.

[0065] At this time, multiple second track wheels 24 are located between two adjacent first track wheels 21 and are spaced apart along the length of the robot body 10; multiple second track wheels 24 are at the same height, so as to increase the contact area of ​​the track 22 with the surface of the photovoltaic panel, thereby improving the grip of the track assembly 20.

[0066] The diameter of the second track wheel 24 is smaller than that of the first track wheel 21, which saves the cost of the track assembly 20.

[0067] In this embodiment of the application, there are two track assemblies 20, which are arranged on both sides of the robot body 10 and connected to the robot body 10. By arranging the two track assemblies 20, the robot body 10 is kept in balance, thereby improving the driving stability of the track assembly 20.

[0068] In this embodiment, a first track wheel 21 is connected to a power assembly 25 so that the first track wheel 21 can be automatically rotated through the power assembly 25, thereby facilitating the rotation of the remaining first track wheels 21, second track wheels 24 and tracks 22.

[0069] At this time, the power assembly 25 includes a first motor 251, a first transmission module 252, and a first rotating shaft 253; the first motor 251 and the first transmission module 252 are both housed within the robot body 10; one end of the first transmission module 252 is connected to the output end of the first motor 251 so that the first transmission module 252 can rotate through the first motor 251, and the other end of the first transmission module 252 is connected to the first rotating shaft 253 so that the first transmission module 252 can drive the first rotating shaft 253 to rotate, and the first rotating shaft 253 is rotatably connected to the robot body 10. This is to facilitate adjusting the position of the first rotating shaft 253 relative to the robot body 10. The first rotating shaft 253 is connected to the first track wheel 21 to drive the first track wheel 21 to rotate. This allows the first track wheel 21 to rotate relative to the robot body 10 via the first motor 251, the first transmission module 252, and the first rotating shaft 253, thereby facilitating the rotation of the remaining first track wheel 21, second track wheel 24, and track 22 to achieve the movement of the track assembly 20. Optionally, the first transmission module 252 can be a gear transmission module or a synchronous transmission module, which is not limited here.

[0070] In this embodiment, the roller brush assembly 30 is disposed on the front or rear side of the robot body 10 and the track assembly 20. The roller brush assembly 30 includes a first connecting frame 31 and a roller brush 32. The roller brush 32 is rotatably connected to the first connecting frame 31. The roller brush 32 rotates along the axial direction of the connection between the roller brush 32 and the first connecting frame 31 to adjust the position of the roller brush 32 relative to the first connecting frame 31. The roller brush 32 is used to clean the photovoltaic panel to remove dust from the photovoltaic panel. The first connecting frame 31 is detachably installed on the robot body 10 so that the first connecting frame 31 can be connected to or detached from the robot body 10. The roller brush 32 covers the robot body 10 and the track assembly 20 in the left-right direction so that the photovoltaic panel locations traversed by the track assembly 20 are all cleaned.

[0071] Meanwhile, the first connecting frame 31 is swayably mounted on the robot body 10 and can swing in the up and down direction to be installed or removed relative to the robot body 10. Thus, the first connecting frame 31 is installed or removed relative to the robot body 10 based on the up and down swing of the first connecting frame 31, avoiding the need to loosen the screws when removing the first connecting frame 31, thereby improving the installation convenience of the first connecting frame 31 relative to the robot body 10 and realizing the quick installation and quick removal of the roller brush assembly 30 relative to the robot body 10.

[0072] The robot body 10 is provided with a first rotating shaft 11; the first connecting frame 31 is provided with a first rotating shaft groove 31a at the end away from the roller brush 32. The first rotating shaft groove 31a is recessed from the back to the front by the first connecting frame 31, and the groove opening of the first rotating shaft groove 31a faces the rear side; when the first connecting frame 31 is installed on the robot body 10, the first rotating shaft 11 is inserted into the first rotating shaft groove 31a so that the first connecting frame 31 can be connected to the robot body 10 through the first rotating shaft 11 and the first rotating shaft groove 31a. The inner contour of the first rotating shaft groove 31a is clearance-fitted with the outer contour of the track wheel frame 23. Under the action of external force, the first connecting frame 31 swings up and down along the axis of the first rotating shaft 11 so as to adjust the position of the first connecting frame 31 relative to the robot body 10.

[0073] The first rotating shaft groove 31a is provided with a side opening 31b, which is used for the first rotating shaft 11 to pass through, so that the first rotating shaft 11 can enter the first rotating shaft groove 31a through the side opening 31b, thereby facilitating the insertion of the first rotating shaft 11 into the first rotating shaft groove 31a, so as to realize the connection between the first connecting frame 31 and the robot body 10.

[0074] The robot body 10 is provided with a second rotating shaft 12, which is located on one side of the first rotating shaft 11. The axis of the second rotating shaft 12 is parallel to the axis of the first rotating shaft 11. The first connecting frame 31 is provided with a receiving groove 31c, which is located on one side of the first rotating shaft groove 31a and is used for the second rotating shaft 12 to pass through, so as to further increase the connection stability of the first connecting frame 31 relative to the robot body 10. When the first connecting frame 31 swings upward relative to the robot body 10, the position of the second rotating shaft 12 relative to the receiving groove 31c is adjusted. When the second rotating shaft 12 disengages from the receiving groove 31c, the first connecting frame 31 can be disassembled relative to the robot body 10, so that the first connecting frame 31 can move relative to the second rotating shaft 12 using the space of the receiving groove 31c. This facilitates the first connecting frame 31 disengaging from the robot body 10. The first connecting frame 31 can be disassembled relative to the robot body 10 by swinging upward, avoiding the need to loosen screws to disassemble the first connecting frame 31, and realizing the rapid disassembly of the roller brush assembly 30 relative to the robot body 10.

[0075] At this time, the receiving groove 31c includes an arc groove 31d and a bottom opening 31e. The bottom opening 31e is connected to the arc groove 31d and is used for the second rotating shaft 12 to pass through, so that the second rotating shaft 12 can move to the arc groove 31d through the bottom opening 31e. When the first connecting frame 31 swings relative to the robot body 10, the relative position of the second rotating shaft 12 and the arc groove 31d gradually changes, so that the first connecting frame 31 can swing relative to the second rotating shaft 12 through the arc groove 31d, thereby facilitating the adjustment of the position of the first connecting frame 31 relative to the robot body 10. The first connecting frame 31 can swing in the up and down direction, thereby realizing the installation or disassembly of the first connecting frame 31 relative to the track wheel frame 23 based on the up and down swing of the first connecting frame 31, avoiding the need to loosen the screws when disassembling the first connecting frame 31, thereby improving the installation convenience of the first connecting frame 31 relative to the robot body 10, and realizing the quick installation and quick disassembly of the roller brush assembly 30 relative to the robot body 10.

[0076] The length of the bottom opening 31e is greater than the width of the arc groove 31d, which improves the convenience of the bottom opening 31e for the second rotating shaft 12 to pass through, thus facilitating the second rotating shaft 12 to enter the arc groove 31d through the bottom opening 31e.

[0077] In this embodiment, the receiving groove 31c further includes a retraction groove 31f. The retraction groove 31f is disposed on one side of the arc groove 31d and connects the arc groove 31d and the bottom opening 31e, so that the second rotating shaft 12 can move to the arc groove 31d or the retraction groove 31f through the bottom opening 31e. When the second rotating shaft 12 moves to the retraction groove 31f through the bottom opening 31e, the first connecting frame 31 can move back and forth relative to the second rotating shaft 12 through the space of the retraction groove 31f, thereby facilitating the adjustment of the front and rear position of the first connecting frame 31 relative to the second rotating shaft 12, and thus facilitating the first rotating shaft groove 31a to disengage from or accommodate the first rotating shaft 11.

[0078] The retraction groove 31f extends from the end of the arc groove 31d near the bottom opening 31e toward the first rotating shaft groove 31a, so that the retraction groove 31f and the bottom opening 31e are arranged in the front-back direction, thereby facilitating the front-back movement of the first connecting frame 31 relative to the second rotating shaft 12, thereby facilitating the adjustment of the front-back position of the first connecting frame 31 relative to the second rotating shaft 12, and thus facilitating the first rotating shaft groove 31a to disengage from or accommodate the first rotating shaft 11.

[0079] In this embodiment of the application, a handle 33 is connected to the top of the first connecting frame 31. The handle 33 is located on the upper side of the first connecting frame 31. The handle 33 is used for the user to lift it so that the user can grasp the handle 33 to swing the first connecting frame 31, thereby improving the gripping convenience of the first connecting frame 31.

[0080] A second rotating shaft 34 is provided between the roller brush 32 and the first connecting frame 31. The second rotating shaft 34 is located between the roller brush 32 and the first connecting frame 31. The roller brush 32 is sleeved on the second rotating shaft 34. The second rotating shaft 34 is rotatably connected to the first connecting frame 31 so as to adjust the position of the second rotating shaft 34 relative to the first connecting frame 31. This allows the roller brush 32 to rotate with the rotation of the second rotating shaft 34, so that the roller brush 32 can rotate relative to the first connecting frame 31 and roll relative to the photovoltaic panel. During the rolling process, the roller brush 32 removes dust from the surface of the photovoltaic panel to achieve a cleaning effect.

[0081] In this embodiment, the water spraying component 40 is disposed on the front side of the track component 20 and sprays water on the front side of the track component 20 to clean the photovoltaic panel. At this time, the water spraying component 40 and the roller brush component 30 clean the photovoltaic panel in a coordinated manner, realizing dual cleaning of the photovoltaic panel, avoiding manual cleaning of the photovoltaic panel, and improving the cleaning effect of the photovoltaic cleaning robot 100 on the photovoltaic panel.

[0082] The water spray assembly 40 includes a support frame 41, a water spray pipe 42, and a water spray head 43. The support frame 41 is connected to the robot body 10 or the first connecting frame 31. The water spray pipe 42 is connected to and supported by the support frame 41 to facilitate fixing the water spray pipe 42 to the support frame 41. The water spray pipe 42 has an inlet 42a and an outlet 42b. The inlet 42a connects to the outlet 42b and is used to connect to a water pipe. The water spray head 43 is connected to the water spray pipe 42 to facilitate... Water from the water pipe flows through the inlet 42a and outlet 42b to the spray head 43. The spray head 43 is provided with a straight spray hole 43a, which is connected to the outlet 42b. The straight spray hole 43a outputs a straight water flow to the water output through the outlet 42b. The output range of the straight water flow is larger than that of the circular water flow, so as to expand the cleaning range through the straight water flow. The cleaning effect of the straight water flow is better and it is suitable for the square shape design of the photovoltaic panel.

[0083] The water spray pipe 42 includes an inlet pipe 421, a manifold pipe 422, and an outlet pipe 423. The inlet pipe 421 has an inlet port 42a for connecting to a water pipe, so that water output from the water pipe can flow through the inlet port 42a to the inlet pipe 421. The manifold pipe 422 is disposed between the inlet pipe 421 and at least one outlet pipe 423, and connects the inlet pipe 421 and the outlet pipe 423, so that water output from the water pipe can flow through the inlet pipe 421 and the manifold pipe 422 to the outlet pipe 423. 2 is connected to the support frame 41 so that the manifold 422 can be fixed to the support frame 41; the water outlet pipe 423 is connected to the spray head 43, so that the water output from the water pipe can flow through the water inlet pipe 421, the manifold 422, and the water outlet pipe 423 to the spray head 43. The spray head 43 outputs a straight water flow. The output range of the straight water flow is larger than that of the circular water flow, so as to expand the cleaning range through the straight water flow. The cleaning effect of the straight water flow is better and it is suitable for the square shape design of the photovoltaic panel.

[0084] The water spray pipe 42 is arranged vertically to improve the smoothness of water flow from the water spray pipe 42, thereby making it easier for the outlet 42b of the water spray pipe 42 to be aligned with the surface of the photovoltaic panel.

[0085] There are multiple water outlet pipes 423, which are arranged sequentially along the length of the manifold 422. All the water outlet pipes 423 are connected to the manifold 422. By arranging multiple water outlet pipes 423, the number of water outlet positions is increased, thereby facilitating the increase of the water outlet range.

[0086] Multiple water outlet pipes 423 are connected to corresponding spray heads 43 so that multiple spray heads 43 can output a straight water flow through multiple water outlets 42b, thereby facilitating the expansion of the cleaning range through the straight water flow. The straight water flows of two adjacent spray heads 43 have overlapping parts so that multiple spray heads 43 can meet the output range, thus facilitating the adaptation to the square shape design of the photovoltaic panel. Therefore, when the straight water flows of two adjacent spray heads 43 have overlapping parts, there is no gap between the straight water flows of two adjacent spray heads 43, thereby avoiding the existence of missed cleaning areas and making better use of the straight water flow arrangement.

[0087] There is a gap between the straight water flow of two adjacent water nozzles 43; the straight water nozzle 43a extends in a straight line and extends in the left and right direction to adapt to different scenarios, so that the straight water nozzle 43a can output a straight water flow. The output range of the straight water flow is larger than that of the circular water flow, so as to expand the cleaning range through the straight water flow. The cleaning effect of the straight water flow is better and it is suitable for the square shape design of the photovoltaic panel. There is no limitation here.

[0088] In this embodiment, the axis of the inlet pipe 421 is parallel to the axis of the outlet pipe 423, so that the water in the inlet pipe 421 can flow directly to the outlet pipe 423 under its own gravity.

[0089] Both ends of the manifold 422 are closed ends; both ends of the manifold 422 are respectively inserted into the support frame 41 so that the manifold 422 can be fixed to the support frame 41 through both ends of the manifold 422, and the middle part of the manifold 422 is in a connected state so that the water in the inlet pipe 421 can flow to the outlet pipe 423 through the manifold 422.

[0090] In this embodiment of the application, the water spray assembly 40 is further provided with two clamping blocks 44. The two clamping blocks 44 are connected to the support frame 41 and clamp both ends of the manifold 422 so that the manifold 422 can be connected to the support frame 41 through the clamping blocks 44, so that the manifold 422 can be fixed to the support frame 41.

[0091] The spray head 43 is provided with a water passage hole 43b, which extends along the axial direction of the spray head 43 and connects the straight spray hole 43a and the outlet 42b. This allows the water output from the outlet 42b to flow through the water passage hole 43b to the straight spray hole 43a, thereby facilitating the output of a straight water flow from the straight spray hole 43a. The output range of the straight water flow is greater than that of the annular water flow, which helps to expand the cleaning range. The straight water flow has a better cleaning effect and is suitable for the square shape design of the photovoltaic panel.

[0092] In this embodiment, the spray head 43 is screwed to the spray pipe 42 so that the spray head 43 is fixed to the spray pipe 42 by means of threaded connection. The spray head 43 is provided with external thread 431, and the spray pipe 42 is provided with internal thread 42c. The external thread 431 engages with the internal thread 42c so that the spray head 43 can be threadedly connected to the spray pipe 42 through the external thread 431 and the internal thread 42c. The spray pipe 42 outputs a straight water flow to the water output from the spray head 43. The output range of the straight water flow is larger than the output range of the circular water flow, so as to expand the cleaning range through the straight water flow. The cleaning effect of the straight water flow is better and it is suitable for the square shape design of the photovoltaic panel.

[0093] The photovoltaic cleaning robot 100 also includes an adsorption component 50, which is connected to the robot body 10 and located at the bottom of the robot body 10. The adsorption component 50 includes a mounting base 6151, a sleeve 52, and an adsorption element 53. The mounting base 6151 is installed on the robot body 10. The sleeve 52 is fixed to the robot body 10. The adsorption element 53 is vertically and vertically inserted through the sleeve 52 and rotates relative to the sleeve 52 to adjust the position of the adsorption element 53 relative to the sleeve 52, thus realizing the lifting and rotating functions of the adsorption element 53 relative to the sleeve 52. During the descent, the adsorption element 53 can contact the surface of the photovoltaic panel and adsorb onto the surface of the photovoltaic panel, so that the adsorption element 53 can adsorb onto the photovoltaic panel, thereby ensuring the positioning of the photovoltaic cleaning robot 100 relative to the photovoltaic panel. Furthermore, the adsorption element 53 rotates relative to the sleeve 52 to adapt to the rotation of the photovoltaic cleaning robot 100 relative to the photovoltaic panel, ensuring the positioning and rotation effects of the adsorption component 50 relative to the photovoltaic panel.

[0094] Optionally, the adsorption assembly 50 further includes a lifting seat 54 and a rotating component 55. The lifting seat 54 is located between the adsorption component 53 and the sleeve 52, and the lifting seat 54 is connected to the adsorption component 53. The lifting seat 54 is movably connected to the sleeve 52 and supports the adsorption component 53, so as to adjust the position of the lifting seat 54 relative to the sleeve 52, thereby facilitating the lifting of the adsorption component 53 as the lifting seat 54 rises and falls, thereby adjusting the position of the adsorption component 53 relative to the sleeve 52.

[0095] The rotating component 55 is located between the adsorption component 53 and the lifting seat 54, and the adsorption component 53 is sleeved on it. Under the action of the rotating component 55, the adsorption component 53 rotates relative to the lifting seat 54, so that the adsorption component 53 can rotate through the rotating component 55. This facilitates the adsorption component 53 to rotate with the lifting seat 54, ensuring the rotation function of the adsorption component 53. Furthermore, the adsorption component 53 rotates relative to the sleeve 52 to adapt to the rotation of the photovoltaic cleaning robot 100 relative to the photovoltaic panel, ensuring the positioning and rotation effects of the adsorption component 50 relative to the photovoltaic panel.

[0096] In this embodiment, the lifting seat 54 is located inside the sleeve 52, and the rotating member 55 is connected to the lifting seat 54. The inner side wall of the rotating member 55 is connected to the adsorption member 53, and the outer side wall of the rotating member 55 is connected to the lifting seat 54, so that the adsorption member 53 can rotate under the rotation of the rotating member 55. Optionally, the rotating member 55 is a brass part or a rotating bearing.

[0097] In this embodiment, a lubricant 521 is provided between the lifting seat 54 and the sleeve 52. The lubricant 521 contacts the inner side wall of the sleeve 52 and the outer side wall of the lifting seat 54 respectively, so as to reduce the friction between the lifting seat 54 and the sleeve 52. Optionally, the lubricant 521 is carbon powder or lubricating oil.

[0098] Therefore, the adsorption component 53 is connected to the lifting seat 54, and the adsorption component 53 rises and falls with the lifting seat 54 to adjust the position of the adsorption component 53 relative to the sleeve 52, thereby facilitating the lifting function of the adsorption component 53. The adsorption end of the adsorption component 53 is located outside the sleeve 52 and passes through the base plate robot body 10, so that the adsorption end of the adsorption component 53 is exposed to the external environment, thereby facilitating the adsorption component 53 to adsorb the photovoltaic panel, thus ensuring the positioning of the photovoltaic cleaning robot 100 relative to the photovoltaic panel. The adsorption component 53 rotates relative to the sleeve 52 to adapt to the rotation of the photovoltaic cleaning robot 100 relative to the photovoltaic panel, ensuring the positioning and rotation effects of the adsorption component 50 relative to the photovoltaic panel.

[0099] In this embodiment, the adsorption assembly 50 further includes a second motor 56, a swing rod 57, and a second connecting frame 58. The swing rod 57 is oscillatingly connected to the mounting base 6151 and swings along the axis of the connection between the swing rod 57 and the mounting base 6151 to adjust the position of the swing rod 57 relative to the mounting base 6151. The fixed end of the second motor 56 is connected to the mounting base 6151, and the output end of the second motor 56 is connected to the swing rod 57, driving the swing rod 57 to swing. This allows the swing rod 57 to swing relative to the mounting base 6151 via the second motor 56, thereby facilitating the automated swinging of the swing rod 57.

[0100] At this time, the second connecting frame 58 is located between the lifting seat 54 and the swing rod 57. The two ends of the second connecting frame 58 are respectively connected to the lifting seat 54 and the swing rod 57. The lifting seat 54 is connected to the swing rod 57 via the second connecting frame 58, and rises and falls relative to the sleeve 52 as the swing rod 57 swings, so that the swing rod 57 can drive the lifting seat 54 to rise and fall relative to the sleeve 52, thereby facilitating the lifting function of the lifting seat 54. During the descent, the adsorption component 53 can contact the surface of the photovoltaic panel and adsorb the surface of the photovoltaic panel, so that the adsorption component 53 can adsorb the photovoltaic panel, thereby ensuring the positioning of the photovoltaic cleaning robot 100 relative to the photovoltaic panel. Then, the adsorption component 53 rotates relative to the sleeve 52 to adapt to the rotation of the photovoltaic cleaning robot 100 relative to the photovoltaic panel, ensuring the positioning and rotation effects of the adsorption component 50 relative to the photovoltaic panel.

[0101] In this embodiment, the second connecting frame 58 is hinged to the middle of the swing rod 57. The two side walls of the second connecting frame 58 are positioned by the inner side wall of the swing rod 57, so as to ensure the positional accuracy of the second connecting frame 58 and the swing rod 57, thereby ensuring the connection stability of the second connecting frame 58 and the swing rod 57.

[0102] In this embodiment, the adsorption member 53 is a suction cup, and the second connecting frame 58 is provided with a clearance hole 58a. The clearance hole 58a is used to avoid the air tube connected to the adsorption member 53, so that the air tube can avoid the second connecting frame 58.

[0103] In this embodiment, the mounting base 6151 has a protruding boss 511, and the swing rod 57 is located between the boss 511 and the second motor 56. One end of the swing rod 57 is hinged to the boss 511, and the other end of the swing rod 57 is connected to the second motor 56, so that the swing rod 57 can be hinged to the mounting base 6151 through the boss 511, thereby facilitating the swing rod 57 to swing relative to the mounting base 6151.

[0104] At this time, the second connecting frame 58 is connected to the sensing arm 581, and the adsorption assembly 50 also includes a sensing switch 59. The sensing switch 59 is connected to the sensing arm 581, and the sensing end of the sensing switch 59 faces the second connecting frame 58. The sensing switch 59 senses the position of the second connecting frame 58.

[0105] The photovoltaic cleaning robot 100 also includes a charging component 60; the charging component 60 includes a mounting base 61 and a charging module 62; the mounting base 61 is installed on the bottom of the robot body 10 and covers the charging module 62. The charging module 62 is used for wireless charging with the charging station for cleaning photovoltaic panels, so that the photovoltaic cleaning robot 100 can achieve wireless charging from the bottom through the charging module 62, avoiding charging through cables and improving the charging convenience of the photovoltaic cleaning robot 100.

[0106] The charging module 62 is a wireless charging module. The charging module 62 is located below the robot body 10 so that the charging module 62 is exposed below the robot body 10, which makes it easy for the charging module 62 to be aligned with the charging station of the cleaning photovoltaic panel to achieve wireless charging. This avoids charging through cables and improves the charging convenience of the photovoltaic cleaning robot 100.

[0107] A sealed space 61a is formed between the mounting base 61 and the bottom of the robot body 10. The charging module 62 is located within the sealed space 61a, so that the mounting base 61 and the robot body 10 can enclose the charging module 62, preventing external dust and water from entering the charging module 62 and ensuring the performance of the charging module 62. At the same time, the outer surface of the mounting base 61 and the robot body 10 protects the charging module 62 from impacts by external debris. The charging module 62 wirelessly charges the charging station of the photovoltaic panel cleaning device, so that the photovoltaic cleaning robot 100 can achieve bottom wireless charging through the charging module 62, avoiding charging through cables and improving the charging convenience of the photovoltaic cleaning robot 100.

[0108] The charging module 62 is connected to the mounting base 61 so that the charging module 62 can be fixed to the mounting base 61, thereby facilitating the mounting base 61 to support the charging module 62, ensuring the distance between the charging module 62 and the ground, avoiding the charging module 62 from contacting the ground, and preventing the charging module 62 from rubbing against the ground.
