[0031] This application provides a photovoltaic cleaning robot.

[0032] Combination Figure 1 and Figure 2 As shown, the photovoltaic cleaning robot provided in this application includes a body 100, a suction head 200, a suction assembly 300, at least one roller brush 400, and a roller brush drive assembly 500.

[0033] The vehicle body 100 includes a mobile chassis 101 and a traveling assembly 102 disposed on the mobile chassis 101, the traveling assembly 102 being capable of driving the mobile chassis 101 to turn. A vacuum head 200 is connected to the mobile chassis 101, and the vacuum head 200 is provided with a vacuum port 201. A vacuum assembly 300 communicates with the vacuum port 201. A roller brush 400 is rotatably disposed at the vacuum port 201. A roller brush drive assembly 500 is used to drive the roller brush 400 to rotate.

[0034] Under the premise of adopting the above technical solution, the photovoltaic cleaning robot is powered by the walking component 102 to achieve turning. The roller brush drive component 500 drives the roller brush 400 to rotate, and the rotation of the roller brush 400 stirs up the dust on the surface of the photovoltaic panel. The dust suction component 300 sucks up and collects the dust through the suction port 201 of the suction head 200, thus cleaning the photovoltaic panel. In this application, the walking component 102 controls the walking direction of the photovoltaic cleaning robot. During the cleaning process, the roller brush 400 does not need to change its rotation direction as in related technologies, which can avoid the photovoltaic panel being re-attached by dust and improve the cleaning effect of the photovoltaic panel.

[0035] Optionally, the walking component can also drive the mobile chassis forward or backward.

[0036] The main body 100 is the main frame of the photovoltaic cleaning robot. The main body 100 includes a mobile chassis 101 and a walking assembly 102 disposed on the mobile chassis 101.

[0037] Optionally, combined Figure 3As shown, the mobile chassis 101 includes a support frame 1011 and a suspension plate disposed on the support frame 1011. The support frame 1011 serves as a fixed support, and the suspension plate disposed on the support frame 1011 facilitates the arrangement and installation of the photovoltaic cleaning robot's components.

[0038] Optionally, combined Figure 3 As shown, the support frame is a rectangular support frame formed by four profiles fixedly connected end to end, or the support frame is a one-piece molded rectangular support frame. The manufacturing process of the support frame can be flexibly selected, as long as it meets the strength and load-bearing requirements of the support frame.

[0039] Optionally, the support frame can be circular, square, or triangular, etc., and the shape of the support frame can be flexibly set according to actual needs.

[0040] In some embodiments, combined with Figure 3 and Figure 7 As shown, the walking assembly 102 includes multiple wheel drive assemblies 1021 and multiple wheels 1022. Each wheel drive assembly 1021 includes a drive motor 1023 mounted on the mobile chassis 101, and each drive motor 1023 is equipped with an output shaft. The multiple wheels 1022 are connected to the output shafts one-to-one. With this configuration, the rotational speed and direction of each wheel 1022 can be controlled independently, enabling the photovoltaic cleaning robot to move flexibly.

[0041] Optionally, the main body 100 is rectangular, and the walking assembly 102 includes four wheel drive assemblies 1021 and four wheels 1022, with the four wheels 1022 respectively located at the four corners of the main body 100. In this way, the main body 100 can be stably supported, the four wheel drive assemblies 1021 provide power, and the photovoltaic cleaning robot has good power, load-bearing capacity and balance.

[0042] In some embodiments, combined with Figure 3 As shown, the walking assembly 102 also includes multiple protective plates 1024 fixed to the mobile chassis 101. Each protective plate 1024 is correspondingly positioned on the side of the drive motor 1023 closest to the wheel 1022. Each protective plate 1024 has a clearance hole through which the output shaft passes to connect to the wheel 1022. By placing the walking assembly 102 between the wheel 1022 and the drive motor 1023, the drive motor 1023 can be protected from environmental factors such as dust, rain, and snow when the photovoltaic cleaning robot cleans dust, ensuring that the drive motor 1023 can operate normally and continuously.

[0043] In some embodiments, combined with Figure 3As shown, the protective plate 1024 is a U-shaped cover, with the opening of the U-shaped cover facing away from the wheel 1022 corresponding to the U-shaped cover. In this way, the protection effect on the drive motor 1023 can be improved.

[0044] Optionally, the drive motor 1023 can be fixed to the mobile chassis 101 via the protection plate 1024, or the drive motor 1023 can be directly fixed to the mobile chassis 101.

[0045] In some embodiments, combined with Figure 3 As shown, the walking assembly 102 also includes multiple motor rear covers 1025, which are correspondingly disposed at the end of the drive motor 1023 away from the wheel 1022. The rear end of the drive motor 1023 is equipped with a motor rear cover 1025 to protect the drive motor 1023 from environmental factors such as dust, rain, and snow, and to ensure that the drive motor 1023 can work normally and continuously.

[0046] In some embodiments, the wheel 1022 is a tireless wheel. A tireless wheel can operate normally without internal air pressure, avoiding the risk of tire blowouts, reducing maintenance needs, extending service life, and enabling operation in harsh environments. By making the wheel 1022 a tireless wheel, the durability of the photovoltaic cleaning robot is improved.

[0047] In some embodiments, combined with Figure 7 As shown, the photovoltaic cleaning robot also includes a vision camera 1016, a lidar 1012, and a controller 1013 mounted on a mobile chassis 101. The lidar 1012 is used to model the surrounding environment, and the vision camera 1016 is used to observe the location of dust on the photovoltaic panels to facilitate fast and efficient cleaning. The lidar 1012 and vision camera 1016 perceive environmental information on the surface of the photovoltaic panels, which is then fed back to the controller 1013 to control the photovoltaic cleaning robot to perform vacuuming and cleaning.

[0048] In some embodiments, combined with Figure 7 As shown, the photovoltaic cleaning robot also includes a start / stop switch 1014 and an emergency stop switch 1015 mounted on the mobile chassis 101. The start / stop switch 1014 is used to start or stop the robot, and the emergency stop switch 1015 is used to stop the operation of the photovoltaic cleaning robot in an emergency. For example, when the photovoltaic cleaning robot loses control of its speed and is about to rush out of the photovoltaic panel or get entangled in foreign objects, the operator can press the emergency stop switch 1015 to cut off the power supply to the photovoltaic cleaning robot and immediately stop its operation.

[0049] The suction head 200 has a suction port 201 on its bottom surface, which can work with the roller brush 400 and the suction assembly 300 to remove dust from the surface of the photovoltaic panel.

[0050] Optionally, combined Figure 4 As shown, the suction head 200 includes an upper cover plate 202, a first side plate 203 and a second side plate disposed opposite to each other, and a front side plate 204 and a rear side plate disposed opposite to each other, wherein the front side plate 204 and the rear side plate are perpendicular to the forward direction of the photovoltaic cleaning robot. The upper cover plate, the first side plate 203, the second side plate, the front side plate 204 and the rear side plate enclose to form the suction head 200, and the lower end of the suction head 200 is open to form a suction port 201.

[0051] Optionally, the suction head 200 includes a first side plate 203 and a second side plate disposed opposite to each other. The first side plate 203 and the second side plate are respectively provided with a first bearing bracket 205 and a second bearing bracket. The two ends of the roller brush 400 are rotatably disposed on the first bearing bracket 205 and the second bearing bracket. The first side plate 203 and the second side plate are parallel to the forward direction of the photovoltaic cleaning robot. Thus, the first side plate 203 and the second side plate can provide effective support for the roller brush 400, which is rotatably disposed at the suction port 201.

[0052] Optionally, the suction head 200 is located on the forward side of the main body 100. In this way, during the operation of the photovoltaic cleaning robot, the suction head 200 first sucks up the dust on the surface of the photovoltaic panel, and the photovoltaic panel that the walking component 102 contacts is a relatively clean area that has been cleaned. This can prevent the walking component 102 from picking up dust and carrying it to other places, which would cause the photovoltaic panel to be re-attached with dust.

[0053] In some embodiments, combined with Figure 2 As shown, the photovoltaic cleaning robot also includes at least one dust removal filament 206, which is correspondingly positioned on the side of the roller brush 400 near the suction port 201. During the rotation of the roller brush 400, the roller brush 400 can sweep over the dust removal filament 206. After the roller brush 400 sweeps up the dust, it is sucked away by the suction port 201 of the suction head 200. For the dust adhering to the roller brush 400, the dust removal filament 206 is specially designed. The dust removal filament 206 is installed on the side of the roller brush 400 near the suction port 201. When the roller brush 400 rotates, it will continuously sweep over the dust removal filament 206, so that the bristles of the roller brush 400 vibrate and shake off the dust adhering to the roller brush 400. The dust is shaken off near the suction port 201, which is conducive to the suction component 300 sucking out the dust in time and avoiding secondary pollution.

[0054] Optionally, the length of the dust-removing filaments 206 is the same as the length of the roller brush 400. This helps to improve the cleaning effect of the dust-removing filaments 206 on the roller brush 400.

[0055] The vacuuming component 300 is used to vacuum and collect dust.

[0056] In some embodiments, combined with Figure 1 and Figure 5 As shown, the vacuuming assembly 300 includes a vacuum pump 301, at least one vacuum bend 302, and a vacuum hose 303. The vacuum pump 301 is mounted on a movable chassis 101. At least one vacuum bend 302 is mounted on the vacuum head 200 and is connected to the vacuum inlet 201. The first end of the vacuum hose 303 is connected to the suction inlet of the vacuum pump 301, and the second end of the vacuum hose 303 is connected to at least one vacuum bend 302. The vacuum pump 301 provides suction, and the vacuum hose 303 connects the vacuum head 200 and the vacuum bend 302. By providing multiple vacuum bends 302, each connected to the vacuum inlet 201, the area to be vacuumed is reduced, and the air velocity at the vacuum bend 302 is increased, thereby improving the vacuuming effect.

[0057] Compared to a single large suction bend, multiple suction bends 3021 can better guide airflow, reducing airflow resistance and turbulence. This helps improve suction efficiency and ensures a more efficient cleaning process. It also reduces the risk of clogging. With a single large suction bend, dust, sand, and other debris may accumulate during turns, increasing the risk of blockage. Multiple suction bends 3021 reduce this risk, allowing dust to enter the suction assembly 300 more smoothly. Furthermore, multiple smaller suction bends 3021 can more flexibly adapt to space constraints in photovoltaic cleaning robot designs, especially at the bottom of the robot or in compact structures. This allows for better utilization of limited space, ensuring the suction inlet of the suction bend 3021 is not interfered with by other components. Additionally, multiple suction bends 3021 provide better structural strength and stability, better withstanding the pressure of suction and reducing potential damage due to structural instability.

[0058] The roller brush drive assembly 500 is used to drive the roller brush 400 to rotate.

[0059] In some embodiments, combined with Figure 6 As shown, the roller brush drive assembly 500 includes a roller brush motor 501 and at least one transmission assembly 502. The roller brush motor 501 is disposed on the suction head 200. Each transmission assembly 502 includes a bearing housing 5021, a drive shaft 5022 disposed on the bearing housing 5021, and a first rotating wheel 5023 disposed on the drive shaft 5022. The drive shaft 5022 of one transmission assembly 502 is connected to the output shaft of the roller brush motor 501. Each first rotating wheel 5023 is connected to the corresponding roller brush 400 through a first transmission belt 5024. The drive shafts 5022 of two adjacent transmission assemblies 502 are connected by a synchronization structure.

[0060] The bearing housing 5021 supports the drive shaft 5022, allowing the drive shaft 5022 to be rotatably mounted on the bearing housing 5021. The rotation of the output shaft of the roller brush motor 501 drives the drive shaft 5022 to rotate, which in turn drives the first rotating wheel 5023 to rotate. Since the first rotating wheel 5023 is connected to the corresponding roller brush 400 via the first transmission belt 5024, the rotation of the first rotating wheel 5023 can drive the corresponding roller brush 400 to rotate. Furthermore, when the photovoltaic cleaning robot includes two or more roller brushes, the synchronization structure can drive the drive shafts 5022 of two adjacent transmission components 502 to rotate, requiring only one roller brush motor 501 to drive all roller brushes 400 to rotate synchronously.

[0061] In some embodiments, combined with Figure 6 As shown, the roller brush drive assembly includes multiple transmission components 502. The synchronization structure includes a timing belt 5025 and a second rotating wheel 5026 disposed on the transmission shaft 5022. The timing belt 5025 is sleeved on the second rotating wheel 5026 of two adjacent transmission components 502. With this configuration, the roller brush motor 501 drives the transmission shaft 5022 directly connected to it to rotate. The timing belt 5025, sleeved on the second rotating wheel 5026 of two adjacent transmission components 502, can drive the two adjacent transmission components 502 to rotate synchronously, thereby driving multiple roller brushes 400 to rotate synchronously. Only one roller brush motor 501 is needed to drive all roller brushes 400 to rotate synchronously.

[0062] In this application, "multiple" means two or more.

[0063] In some embodiments, combined with Figure 8 As shown, the photovoltaic cleaning robot also includes a base plate 103 disposed below the mobile chassis 101, and the base plate 103 and the mobile chassis 101 are fixedly connected by a connecting column 104. The base plate 103 is used to support other structures of the photovoltaic cleaning robot, such as a development board.

[0064] The technical solutions of this application have been described in conjunction with the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions resulting from these changes or substitutions will all fall within the scope of protection of this application.
