This is the elongation process, then the third rotating shaft 34 and the fifth rotating shaft 36 When the telescopic rod between the two starts to shrink, and the output shaft of the rotary motor 29 starts to rotate counterclockwise, the insertion rod 38 threadedly connected to the output shaft of the rotary motor 29 starts to move in the direction close to the sleeve rod 37, which is the shrinking process. At this time, the square frame 5 is located on the side of the first rotating shaft 32 and begins to rise upward with the third rotating shaft 34 as the center, and the square frame 5 is located on the side of the third rotating shaft 34 and begins to descend downward with the third rotating shaft 34 as the center. When the telescopic rod between the first rotating shaft 32 and the fourth rotating shaft 35 is contracted, when the output shaft of the rotary motor 29 starts to rotate counterclockwise, the insertion rod 38 threadedly connected with the output shaft of the rotary motor 29 begins to move toward the shaft close to the sleeve rod 37. direction movement, this is a shrinking process, then the telescopic rod between the third rotating shaft 34 and the fifth rotating shaft 36 begins to stretch, and when the rotary motor 29 starts to rotate clockwise, the output shaft of the rotary motor 29 also starts to rotate clockwise at this time, At this time, the insertion rod 38 threadedly connected with the output shaft of the rotary motor 29 starts to move away from the sleeve rod 37 , which is an elongation process. At this time, the square frame 5 is located on one side of the first rotating shaft 32 with the second rotating shaft 33 as the center Begin to lower down, the square frame 5 is located on the side of the third rotating shaft 34 and starts to rise upward with the second rotating shaft 33 as the center. When the angle between the square frame 5 and the ground is adjusted to an appropriate angle, the rotating motor 29 stops working at this time. , the first rotating shaft 32 and the third rotating shaft 34 are hinged with the square frame 5, the fourth rotating shaft 35 and the fifth rotating shaft 36 are hinged with the two triangular support frames 31, which can make the upper and lower ends of the two telescopic rods change different angles. 3. When sensing that the photovoltaic power generation panel 2 is adjusted to an appropriate illumination angle, the controller 4 controls the rotating motor 29 and the telescopic motor 39 to stop working, and the entire cleaning and illumination angle adjustment process is completed.
