[0002] As the global demand for renewable energy grows, photovoltaic power generation has been widely used as a clean and efficient energy source. Especially in large-scale photovoltaic power generation bases, the number and area of ​​photovoltaic panels are huge, and it is particularly important to ensure their operating efficiency. However, photovoltaic panels are easily affected by environmental factors during long-term use, such as dust, bird droppings, leaves and other dirt, which cause the light transmittance on the surface of the photovoltaic panels to decrease, thereby affecting the power generation efficiency of the photovoltaic system and the overall economic benefits.

[0003] Traditional photovoltaic panel cleaning methods mainly rely on manual cleaning or the use of simple mechanical equipment. Manual cleaning is not only costly, but also time-consuming and labor-intensive, and has great safety hazards. In addition, the safety risks are also increased when workers operate various cleaning equipment. Simple mechanical cleaning equipment often cannot adapt to complex environments, and the cleaning effect is not ideal, which often leads to incomplete cleaning. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent cleaning robot suitable for photovoltaic panels in large bases. The modular design makes the maintenance and upgrading process simpler and more efficient. The control system can clean the roller brush assembly and the motion assembly without human supervision. The roller brush with hard bristles can be used to directly perform dry brush cleaning on the photovoltaic panels to reduce the consumption of water resources.

[0005] To achieve the above-mentioned object, the present invention provides an intelligent cleaning robot suitable for photovoltaic panels of large bases, comprising a supporting frame, a roller brush assembly is installed on the supporting frame, the roller brush assembly comprises a mounting frame, a roller brush motor is installed on the mounting frame, the roller brush motor is connected to the roller brush through a coupling, a support block is provided in the middle of the roller brush, the support block is installed on the supporting frame, motion components are provided on both sides of the roller brush, and the roller brush assembly and the motion component are both connected to a control system; The motion component includes a T-shaped bracket, on which a walking wheel motor is provided. The walking wheel motor is connected to a driving wheel. The driving wheel and two driven wheels are driven by a belt. Both of the two driven wheels are connected to the walking wheel. Three auxiliary wheels are provided at the bottom of the T-shaped bracket.

[0006] Preferably, a tensioning wheel is provided between the driving wheel and the driven wheel which is far away, and the tensioning wheel is fixed on the T-shaped bracket through a mounting plate, and a sliding groove is provided on the mounting plate.

[0009] Preferably, the roller brush motor and the two travel wheel motors are connected to an electric control box, and the electric control box is located at one end of the support frame away from the roller brush motor.

[0010] Therefore, the present invention adopts the above-mentioned intelligent cleaning robot suitable for large-scale photovoltaic panels, which has the following beneficial effects: The modular design makes the maintenance and upgrade process simpler and more efficient.

[0018] Embodiment 1 like Figures 1 to 5 As shown, the present invention provides an intelligent cleaning robot suitable for photovoltaic panels of large bases, including a support frame 5. The support frame 5 supports the motion component and the roller brush component, which can effectively ensure the overall structural strength of the robot and provide an installation position for the robot shell 1. A shell 1 is provided above the support frame 5. The shell 1 is installed on the support frame 5 to shield and protect the entire robot. A photovoltaic power generation panel 2 is provided on the top of the shell 1. The photovoltaic power generation panel 2 can convert light energy into electrical energy to provide power for the robot. An electric control switch and an emergency stop button are integrated on one side of the top of the shell 1, which can be controlled in an emergency.

[0019] A roller brush assembly is installed on the support frame 5, and the roller brush assembly includes a mounting frame 9, and a roller brush motor 8 is installed on the mounting frame 9, and the mounting frame 9 provides support for the roller brush motor 8. The roller brush motor 8 is connected to the roller brush 16 through a coupling 18, and the roller brush motor 8 provides power for the rotation of the roller brush 16. When the roller brush motor 8 is started, the roller brush 16 can be driven to rotate through the coupling 18. A support block 17 is provided in the middle of the roller brush 16, and a second bearing is provided inside the support block 17. The support block 17 is installed on the support frame 5. The support block 17 can provide support for the middle of the roller brush 16 to prevent the roller brush 16 from being deformed due to excessive length, and ensure the structural strength of the roller brush 16. The second bearing facilitates the rotation of the roller brush 16. The roller brush 16 adopts a hard brush, and the roller brush 16 directly dry brushes to clean the photovoltaic panel, which can effectively remove stains without damaging the photovoltaic panel.

[0020] Both ends of the roller brush 16 pass through the T-shaped bracket 13 respectively, and a first bearing 19 is provided on the T-shaped bracket 13. The first bearing 19 is a square seat bearing, and a through hole corresponding to the first bearing 19 is provided on the T-shaped bracket 13 to facilitate the installation of the first bearing 19. A second bearing sleeve 20 is installed on the side of the first bearing 19 away from the roller brush motor 8. The second bearing sleeve 20 reduces the friction between the roller brush 16 and the hole, thereby extending the service life.

[0021] A motion assembly is provided on both sides of the roller brush 16, and the motion assembly includes a T-shaped bracket 13, which is the main supporting structure of the motion assembly. A walking wheel motor 7 is provided on the T-shaped bracket 13, and the walking wheel motor 7 is connected to the driving wheel 10. The walking wheel motor 7 outputs power to the driving wheel 10 to drive the driving wheel 10 to rotate. The driving wheel 10 and the two driven wheels 11 are driven by a belt 14, and the two driven wheels 11 are coaxially connected to the walking wheel 3. The driven wheel 11 and the walking wheel 3 are respectively located on both sides of the T-shaped bracket 13, and a first bearing sleeve 15 is provided between the driven wheel 11 and the T-shaped bracket 13. The rotation of the driving wheel 10 can drive the two driven wheels 11 to rotate through the belt 14, and the rotation of the driven wheel 11 will drive the walking wheel 3 to rotate. The walking wheel 3 can move along the upper edge of the photovoltaic panel, thereby realizing the movement of the robot along the photovoltaic panel. Three auxiliary wheels 4 are provided at the bottom of the T-shaped bracket 13, and the auxiliary wheels 4 are stuck on the side edge of the edge of the photovoltaic panel to prevent slipping due to tilting, and play a role of support and protection.

[0022] A tensioner 12 is provided between the driving wheel 10 and the driven wheel 11 which is far away. The tensioner 12 is fixed on a T-shaped bracket 13 through a mounting plate, and a slide groove is provided on the mounting plate. The tensioner 12 can move along the slide groove on the mounting plate to adjust the tightness of the belt 14 to ensure efficient transmission of power. If the desired effect cannot be achieved by adjusting the tensioner 12, the coupling 18 between the roller brush motor 8 and the roller brush 16 can be removed, and the roller brush 16 can be removed from the T-shaped bracket 13, and the belt 14 can be replaced.

[0023] The roller brush motor 8 and the two running wheel motors 7 are connected to the electric control box 6, which is located at one end of the support frame 5 away from the roller brush motor 8. The electric control box 6 controls the roller brush motor 8 and the running wheel motor 7. The roller brush assembly and the motion assembly are both connected to the control system. The control system can control the intelligent cleaning robot provided by the present invention to perform precise cleaning according to the specific lossless condition of the photovoltaic panel, with a higher level of automation and intelligence. The control system supports remote monitoring and management, and provides real-time cleaning status, data analysis and maintenance suggestions through the connection with the user's smart device through WIFI or Internet of Things technology. Users can perform remote monitoring at any location through mobile phone applications or PC terminals. This remote monitoring not only improves management efficiency, but also facilitates users to grasp the cleaning status of photovoltaic panels at any time and realize scientific management.

[0024] The intelligent cleaning robot can also form a closed-loop system of self-improvement through continuous learning and optimization. The data and experience accumulated by the robot during the cleaning process can be fed back to the control system, making it more intelligent in subsequent tasks and providing personalized cleaning solutions for different environments and photovoltaic bases. It can not only improve the efficiency of photovoltaic power generation, reduce cleaning costs, and ensure safety, but also provide strong technical support for the efficient operation of large-scale photovoltaic power generation bases.

[0025] When the intelligent cleaning robot for photovoltaic panels of a large base provided by the present invention is used, the intelligent cleaning robot is parked in a base station on one side of the photovoltaic array when not working. When the control system autonomously detects that the photovoltaic panel needs to be cleaned, the intelligent cleaning robot can autonomously start the cleaning operation. When working, the walking wheel motor 7 drives the motion device to move laterally along the photovoltaic panel, and at the same time, the roller brush motor 8 drives the roller brush 16 to rotate to clean the stains on the surface of the photovoltaic panel. The stains on the surface of the photovoltaic panel can be effectively cleaned through a back and forth movement. This process does not require manual intervention, which can effectively reduce the operation and maintenance costs of large photovoltaic bases and ensure the power generation efficiency of large-base photovoltaic stations.

[0026] Therefore, the present invention adopts the above-mentioned intelligent cleaning robot suitable for large-base photovoltaic panels, and adopts a modular design to make the maintenance and upgrade process simpler and more efficient. The control system can clean the roller brush assembly and the motion assembly without anyone managing it, and use a roller brush with hard bristles to directly dry-brush clean the photovoltaic panels, thereby reducing the consumption of water resources.
