[0042] Please refer to Figures 1 to 4 As shown, this utility model provides a flexible bracket photovoltaic cleaning robot 100 capable of autonomously detecting the dust content of photovoltaic modules. It is used to clean flexible bracket photovoltaic modules and includes a walking beam 1, an upper walking device 2, and a lower walking device (not shown) located at both ends of the walking beam 1. The walking beam 1 has several cleaning components 4 that abut against the flexible bracket photovoltaic modules. The walking beam 1 also has solar panels 5 and a central control system 6. A camera system 7 for image acquisition of the photovoltaic modules is located on one side of the walking beam 1. The camera system 7, solar panels 5, upper walking device 2, and lower walking device are all electrically connected to the central control system 6. The camera system 7 transmits the acquired images back to a preset program to detect the dust content of the photovoltaic modules. By setting the camera system 7 on the flexible bracket cleaning robot to obtain surface images of the photovoltaic modules, and by ensuring that the camera system 7 and the cleaning robot are always in a relatively fixed position, the acquired images are more stable and can more accurately reflect the surface condition of the photovoltaic modules. This provides maintenance strategy support for the cleaning and maintenance of photovoltaic power plants, reduces the cost of power plant maintenance, and has a simple overall structure.

[0043] In this embodiment, the imaging system 7 is assembled to one side of the traveling beam 1 corresponding to the forward direction via mounting component 73, and the imaging system 7 is located 600mm-650mm above the photovoltaic module. Positioning the imaging system 7 on the forward side of the traveling beam 1 allows it to capture a wider image of the photovoltaic module. Admittedly, the height setting of the imaging system 7 relative to the photovoltaic module is related to the lens focal length and sensor of the camera 71; however, the height setting of the imaging system 7 relative to the photovoltaic module in this invention is not limited by the data range in the above embodiments. In this invention, the camera 71 uses a large-size sensor industrial camera to obtain clear images of the photovoltaic module's status.

[0044] In this embodiment, the upper walking device 2 is provided with a first protective cover 21, and the lower walking device is provided with a second protective cover 31. By providing the first protective cover 21 and the second protective cover 31, the upper walking device 2 and the lower walking device can be protected, reducing the impact of wind, sand, rain, snow, bird droppings, and other contaminants on their mechanical components, thus reducing the impact on the service life of the cleaning robot.

[0045] The mounting assembly 73 includes a support rod 731 and an assembly block 732 for fixing the support rod 731 to the traveling beam 1.

[0046] Specifically, the support rod 731 has an L-shaped structure. The first end of the support rod 731 is fixedly connected to the shooting system 7, and the second end of the support rod 731 is connected to the assembly block 732. The assembly block 732 includes a base 733 and a base portion 734. The center of the base portion 734 has a first assembly hole 735 through which the second end of the support rod 731 passes. The base portion 734 has a threaded hole 736 penetrating the base 733. A fastener 75 passes through the threaded hole 736 to fix the assembly block 732 onto the traveling beam 1. The centerline of the first assembly hole 735 is perpendicular to the centerline of the threaded hole 736. In a preferred embodiment, the base 733 has a third assembly hole 737, and a first fastener 77 passes through the third assembly hole 737 to fix the assembly block 732 onto the traveling beam 1.

[0047] In this utility model, the solar panel 5 is positioned near the upper walking device 2, and the central control system 6 is positioned near the lower walking device. The imaging system 7 is positioned in the middle of the walking beam 1, and the distance between the vertical portion of the support rod 731 and the walking beam 1 is 30mm-50mm. If the solar panel 5 is positioned beyond the physical center of the walking beam 1, the distance between the vertical portion of the support rod 731 and the frame of the solar panel 5 is 30mm-50mm. An arc-shaped transition structure is provided at the connection between the vertical and horizontal portions of the L-shaped support rod 731.

[0048] In this embodiment, the shooting system 7 includes a housing 70 and a camera 71 disposed within the housing 70. The housing 70 consists of a detachable bottom shell 701, a top cover 704, a front cover 705, and a rear cover 706, with the front cover 705 hinged to the top cover 704. The front cover 705 is used when the flexible support cleaning robot is in operation.

[0049] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
