[0017] like Figure 1-5As shown, the visual monitoring system of the photovoltaic module cleaning machine, the cleaning machine moves on the photovoltaic module, the cleaning machine includes a frame 8, a rotating shaft and a rotating motor driving the rotating shaft are installed in the frame 8, and a plurality of brushes are installed on the circumferential surface of the rotating shaft.

[0018] Further, the camera mounting frame includes a mounting seat 40 and a rotating arm 41. The mounting seat 40 is fixed to the middle part of the frame 8. A circular groove 42 is provided on the mounting seat 40. A rotating plate 43 is rotatably installed in the circular groove 42. A connecting shaft 44 is fixedly connected to the rotating plate 43. The connecting shaft 44 is fixedly connected to one end of the rotating arm 41. The CCD industrial recognition camera is installed at the other end of the rotating arm 41. Two arc-shaped notches 45 are arranged opposite to each other on the rotating plate 43. Two telescopic channels 46 are arranged opposite to each other on the mounting seat 40. A locking spring 47 is movably inserted in the telescopic channel 46. The locking spring 47 is inserted into the locking channel 46. One end of the spring 47 is located in the circular groove 42 and is connected to a clamping head 48 matching the arc-shaped notch 45. The other end of the clamping spring 47 is fixed on the mounting seat 40.
