[0055] The specific working principle is as follows:

[0056] When in use, the rest of the structure is fixed by the fixing component 6 on one side of the main body 1. When in use, the displacement hoop 61 is adjusted with the horizontal support plate 63 running through it, and the connecting block 62 is fixed by bolting the bearing block 11. When displacement is required, the slide groove 64 on the bearing block 11 is matched with the matching slider 612 to move horizontally in the slide groove 64, so that the protrusion 613 is displaced left and right, and the rolling wheel assists in rolling. When it reaches the specified spacing, the bolt can be locked in the bolt hole 611 for installation and fixation. After fixation, the high-definition camera 2 is nested into the sleeve 17 under the serial plate 16 at one end of the turning plate 12 through the rear fixing frame, so that the top is nested in the auxiliary rotating block 15. When the encoding motor 5 is triggered after the program is reversed, the encoding motor 5 drives the meshing gear ring 14 on the turning plate 12 to rotate, and the serial plate 16 is driven to displace. During the displacement process, the concave block in the auxiliary rotating block 15 fixes the top column 152 of 151. During the fixing process The rubber head 155 embedded on the surface reduces wear, and the card slots 153 on both sides engage with the fixing frame of the high-definition camera 2 to play a linkage role, so as to change the angle and monitor the blind spots in the industrial park in real time. At the same time, the wireless transmitter 34 on the photovoltaic device 3 can also transmit the real-time monitored video to the terminal, so as to achieve Internet of Things intercommunication. In order to enable the solar panel 37 in the fixed frame 31 to be self-sufficient for the real-time monitoring equipment, the encoding motor 5 rotates during use, and the pull rope 35 wrapped around the surface will be released, so that the transmission rod 381 makes the rollers 383 on both sides of the transmission rod 381 slide on the slide rail 36 when the pull rope becomes loose, so that the scraping strip a2 at the top of the scraping block 384 is displaced on the surface of the solar panel 37. During the displacement process, the spring a3 cooperates with the embedded column a4 to apply pressure, and cooperates with the scraping block 384 to clean the dust on the surface of the solar panel 37. At the same time, when the encoding motor 5 reverses, the pull rope 35 is reset, and the scraping block 384 restores the fixed frame 31 to the top.

[0057] It should be understood that the embodiments disclosed in the present invention are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features understood by ordinary technicians in the relevant field. It should also be understood that the terms used herein are only used for the purpose of describing specific embodiments and are not meant to be limiting.
