[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) During maintenance, the operator starts the drive motor to drive the active bevel gear to rotate. When the active bevel gear rotates, the threaded rod is driven to rotate through the driven bevel gear. When the threaded rod rotates, the threaded sleeve is driven to move downward. When the threaded sleeve moves downward, the moving block drives the two limit blocks to slide along the inside of the two limit grooves, thereby increasing the stability of the threaded sleeve when it moves. When the moving block moves downward, the mounting plate and the photovoltaic panel are driven downward through the support rod;

[0016] When the threaded sleeve moves downward, it will also drive the connecting block downward through the supporting arm, and when the connecting block moves downward, it will drive the signal light downward through the plug-in socket, and when the connecting block moves downward, it will drive the two contact heads to move downward along the two limit strips. Since the two limit strips are in the shape of oblique strips that are wide at the top and narrow at the bottom, when the connecting block moves downward, the elastic force of the two springs will push the two contact heads to move backwards, and when the two contact heads move backwards, they will drive the two clamping rods to move backwards, and when the two clamping rods move backwards, they will drive the slider to slide inside the slide slot, thereby increasing the stability of the two clamping rods when moving backwards. When the two clamping rods move backwards, they will exit the inside of the two clamping holes to release the limit, and when the signal light moves down to the bottom, the operator can directly pull the plug-in socket on the signal light out of the slot of the connecting block, so as to quickly disassemble the signal light, which is convenient for the operator to replace;

[0017] (2) When there is a lot of dust on the photovoltaic panel, the operator starts the servo motor to drive the lower sprocket to rotate, and the lower sprocket drives the transmission pin to rotate through the turntable. When the transmission pin rotates, it drives the transmission bar to move up and down. When the transmission bar moves, it drives the two sliding sleeves to slide along the surfaces of the two sliding rods, thereby increasing the stability of the transmission bar when it moves. When the transmission bar moves up and down, it drives the cleaning brush to move up and down through the connecting rod, thereby cleaning the dust on the surface of the photovoltaic panel;

[0018] When the lower sprocket rotates, it also drives the upper sprocket to rotate along the support frame through the chain. When the upper sprocket rotates, it drives the large gear to rotate along the positioning seat. When the large gear rotates, it drives the small gear to rotate along the rotating shaft. When the small gear rotates, it drives the shaft rod to rotate inside the shaft sleeve. When the shaft rod rotates, it drives the blower fan to rotate and blow air. The air blown by the blower fan is discharged through the air outlet, blowing away the dust swept by the cleaning brush, and at the same time blowing away the dust contaminated on the cleaning brush, so as to avoid the dust adhering to the cleaning brush and improve the cleaning effect of the cleaning brush.

[0019] (3) The fixed limit can be released simultaneously when the height of the traffic light is lowered, so that the light can be easily disassembled, and the dust on the cleaning brush can be blown away while cleaning the photovoltaic panel, thereby improving the cleaning effect.
