Description

Technical Field

[0002] Solar photovoltaic panels are important structures in solar power generation systems and are usually installed in areas far from cities, near roads or in desert environments. These environments have strong winds and sand, and the environment is harsh, making it easy for impurities such as dust or bird droppings to adhere to the photovoltaic panels. This will reduce the ability of the component surface to reflect and absorb sunlight, resulting in a decrease in the output power of the photovoltaic module.

[0045] Referring to Figure 1 and Figure 2 , a solar photovoltaic panel cleaning robot provided by an embodiment of the present application includes:

[0046] a housing 10;

[0047] a traveling assembly 20, the traveling assembly 20 is connected to the housing 10, and the traveling assembly 20 is used to drive the robot to travel;

[0048] a cleaning assembly 30, the cleaning assembly 30 includes a cleaning frame 301, a cleaning brush 302 and a driving unit 303, the cleaning frame 301 is connected to the housing 10, the cleaning brush 302 is movably connected to the cleaning frame 301, the driving unit 303 is disposed on the cleaning frame 301, and drives the cleaning brush 302 to reciprocate along the width direction of the cleaning frame 301.

[0049] The present disclosure provides a solar photovoltaic panel cleaning robot, including a housing 10 and a traveling assembly 20, the traveling assembly 20 is connected to the housing 10, and the traveling assembly 20 is used to drive the robot to travel to a designated position. It further includes a cleaning assembly 30, the cleaning assembly 30 includes a cleaning frame 301, a cleaning brush 302 and a driving unit 303, the cleaning frame 301 is connected to the housing 10, the cleaning brush 302 is movably connected to the cleaning frame 301, the driving unit 303 is disposed on the cleaning frame 301, and drives the cleaning brush 302 to reciprocate along the width direction of the cleaning frame 301. The driving unit 303 can drive the cleaning brush 302 to reciprocate on the surface of the photovoltaic panel, so that during the cleaning process, the bristles of the cleaning brush 302 can be in full contact with the surface of the photovoltaic panel, and wipe and remove dirt such as dust and bird droppings on the surface. After the cleaning work at the designated position is completed, the traveling assembly 20 can be driven to travel to the next area to be cleaned and continue the cleaning operation until the cleaning work of all photovoltaic panels is completed.

[0050] With the above settings, the cleaning robot in the present disclosure can perform a more comprehensive and in-depth cleaning of the surface of the photovoltaic panel through the reciprocating motion of the cleaning brush 302 and the walking of the walking assembly 20. For stubborn dirt such as resin and bird droppings, the reciprocating motion of the cleaning brush 302 can increase the friction force and cleaning intensity on the dirt, effectively avoiding dirt residue and improving the cleaning quality. Since the dirt can be removed more effectively, the need for secondary cleaning is reduced, greatly improving the efficiency of the cleaning operation. At the same time, the reciprocating motion of the cleaning brush 302 and the walking of the robot can be carried out simultaneously, shortening the cleaning time and improving the work efficiency.

[0051] Specifically for the cleaning frame 301, the cleaning frame 301 includes positioning side plates 3011 and a connecting member 3012. The connecting member 3012 connects the positioning side plates 3011. The positioning side plates 3011 are arranged on both sides of the cleaning brush 302. The positioning side plates 3011 are provided with guide holes 3013, and the guide holes 3013 are elongated holes arranged along the width direction of the cleaning frame 301. Both ends of the cleaning brush 302 are provided with rotating shafts 3021, and the rotating shafts 3021 are inserted into the guide holes 3013. The driving unit 303 drives the rotating shafts 3021 to move in the guide holes 3013. In this embodiment, the cleaning frame 301 is connected to the housing 10. The cleaning frame 301 specifically includes positioning side plates 3011 and a connecting member 3012. The positioning side plates 3011 and the connecting member 3012 together form a T-shaped structure. The positioning side plates 3011 are further provided with guide holes 3013, and the guide holes 3013 are elongated holes arranged along the width direction of the cleaning frame 301. Both ends of the cleaning brush 302 are provided with rotating shafts 3021, and the rotating shafts 3021 are inserted into the guide holes 3013. The diameter of the rotating shafts 3021 matches the inner diameter of the guide holes 3013, ensuring that the rotating shafts 3021 can rotate freely in the guide holes 3013 and can also move along the guide holes 3013 under the action of the driving unit 303.

[0052] In addition, as Figure 3 and Figure 4 shown, the cleaning assembly 30 further includes a first water guide pipe 304 and a second water guide pipe 305. Both ends of the first water guide pipe 304 and the second water guide pipe 305 are communicated with the positioning side plates 3011. The first water guide pipe 304 is provided with a first spray head group 3041, and the second water guide pipe 305 is provided with a second spray head group 3051. The first water guide pipe 304 and the second water guide pipe 305 are respectively connected to the driving unit 303, and the driving unit 303 is adapted to drive the first water guide pipe 304 and the second water guide pipe 305 to rotate in opposite directions. During the cleaning process, the first water guide pipe 304 and the second water guide pipe 305 can rotate in opposite directions under the action of the driving unit 303. The first spray head group 3041 and the second spray head group 3051 can spray water on the surface of the photovoltaic panel, and in cooperation with the cleaning of the cleaning brush 302, the cleaning effect can be improved, especially for stubborn dirt, which can play a role in softening and flushing.

[0053] Specifically for the driving unit 303, as Figures 5 to 8 shown, the driving unit 303 is arranged on the positioning side plate 3011. The driving unit 303 includes a driving motor 3031, a guide wheel 3032, a first synchronous pulley 3033, a second synchronous pulley 3034, a synchronous belt 3035, a first gear 3036, a second gear 3037 and a connecting rod 3038. The first synchronous pulley 3033 is coaxially arranged with the guide wheel 3032, and the second synchronous pulley 3034 is coaxially arranged with the first gear 3036. The output shaft of the driving motor 3031 is connected to the guide wheel 3032. The synchronous belt 3035 is used to connect the first synchronous pulley 3033 and the second synchronous pulley 3034. The first gear 3036 and the second gear 3037 are meshed. The first gear 3036 is connected to the first water guide pipe 304, and the second gear 3037 is connected to the second water guide pipe 305. The eccentric position of the guide wheel 3032 is connected to the rotating shaft 3021 of the cleaning brush 302 through the connecting rod 3038.

[0054] During the working process, the driving motor 3031 drives the guide wheel 3032 to rotate. The rotation of the guide wheel 3032 will drive the first synchronous pulley 3033 coaxially arranged with it to rotate. The first synchronous pulley 3033 and the second synchronous pulley 3034 are connected by the synchronous belt 3035. Therefore, the second synchronous pulley 3034 also rotates synchronously under the action of the synchronous belt 3035. The second synchronous pulley 3034 is coaxially arranged with the first gear 3036, and the first gear 3036 also rotates synchronously. The second gear 3037 is meshed with the first gear 3036, and the second gear 3037 rotates relatively synchronously with the first gear 3036. And because the eccentric position of the guide wheel 3032 is connected to the rotating shaft 3021 of the cleaning brush 302 through the connecting rod 3038, the rotation of the guide wheel 3032 will drive the rotating shaft 3021 to move along the width direction of the cleaning frame 301 in the guide hole 3013. Through the above transmission structure, the power of the driving motor 3031 can drive the reciprocating movement of the cleaning brush 302 and the rotation of the first water guide pipe 304 and the second water guide pipe 305 at the same time. Thus, while the cleaning brush 302 reciprocates, the first water guide pipe 304 and the second water guide pipe 305 can also be used to spray water on the surface of the photovoltaic panel, improving the cleaning effect on the surface of the photovoltaic panel.

[0055] Furthermore, a roller group 306 is arranged on the side wall of the guide hole 3013, and the rotating shaft 3021 of the cleaning brush 302 is in rolling contact with the roller group 306. The roller group 306 is arranged on both the upper wall and the lower wall of the guide hole 3013. The rotating shaft 3021 of the cleaning brush 302 is in rolling contact with the roller group 306, reducing the friction force and making the movement of the cleaning brush 302 smoother.

[0056] Further, a limiting member 3022 is provided at one end of the rotating shaft 3021 passing through the guiding hole 3013. The limiting member 3022 is provided with a limiting surface parallel to the end surface of the rotating shaft 3021. The limiting surface is used to abut against the roller group 306 to realize the axial limiting of the rotating shaft 3021. A limiting member 3022 is provided at one end of the rotating shaft 3021 passing through the guiding hole 3013. The limiting member 3022 is provided with a limiting surface parallel to the end surface of the rotating shaft 3021. The limiting surface is used to abut against the roller group 306 to realize the axial limiting of the rotating shaft 3021 and prevent the cleaning brush 302 from axially shifting during movement.

[0057] In an embodiment of the present application, it further includes an adjusting assembly 40. One end of the adjusting assembly 40 is connected to the housing 10, and the other end of the adjusting assembly 40 is connected to the connecting member 3012. The adjusting assembly 40 is used to adjust the position of the cleaning assembly 30. One end of the adjusting assembly 40 is connected to the housing 10, and the other end of the adjusting assembly 40 is connected to the connecting member 3012, so as to be able to adjust the position of the cleaning assembly 30 relative to the housing 10 and expand the cleaning range of the cleaning assembly 30.

[0058] Specifically, the adjusting assembly 40 includes:

[0059] A driving seat 401, which is arranged on the side of the connecting member 3012 away from the cleaning brush 302;

[0060] An adjusting seat 402, which is arranged on the side of the driving seat 401 away from the connecting member 3012. The adjusting seat 402 is rotatably connected to the driving seat 401, and the adjusting seat 402 is used to control the rotation of the driving seat 401;

[0061] A connecting arm assembly 403, which is connected to the adjusting seat 402;

[0062] A rotating adjusting member, the first end of the rotating adjusting member is connected to the connecting arm assembly 403, and the second end of the rotating adjusting member is connected to the housing 10. The rotating adjusting member can rotate relative to the housing 10.

[0063] In the above embodiment, the adjusting seat 402 can adjust the rotating position of the cleaning brush 302. The connecting arm assembly 403 is used to connect the adjusting group and the rotating adjusting member. The two ends of the rotating adjusting member are respectively connected to the connecting arm assembly 403 and the housing 10, further increasing the flexibility of adjusting the position of the cleaning assembly 30.

[0064] Specifically for the connecting arm assembly 403, the connecting arm assembly 403 includes;

[0065] A first pneumatic adjusting arm 4031, which is arranged at one end of the adjusting seat 402 away from the driving seat 401;

[0066] The second pneumatic adjusting arm 4032 is arranged at one end of the first pneumatic adjusting arm 4031 away from the adjusting seat 402. The first pneumatic adjusting arm 4031 is used to adjust the included angle formed by the first pneumatic adjusting arm 4031 and the second pneumatic adjusting arm 4032. By adjusting the included angle between the first pneumatic adjusting arm 4031 and the second pneumatic adjusting arm 4032, the height and position of the cleaning assembly 30 can be changed to adapt to photovoltaic panels of different types and installation angles.

[0067] Specifically for the traveling assembly 20, the traveling assembly 20 includes traveling wheels and crawlers. The traveling wheels are arranged on both sides of the housing 10, and the crawlers are arranged on the traveling wheels. This crawler-type traveling assembly 20 can provide good grip and adaptability, enabling the robot to walk stably on the bottom surfaces with different surface conditions. Moreover, the traveling assembly 20 can also walk on the photovoltaic panel and adapt to the photovoltaic panel arranged in the horizontal direction.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0069] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
