[0057] In this embodiment, referring to Figure 1 and Figure 4 , initially, the photovoltaic panel 3 faces east, and as the sun moves from east to west, the synchronous shaft 5 is pushed to drive the mounting bracket 7 to overturn the steering rod 4, so that the photovoltaic panel 3 faces west (as shown in Figure 9 ). In this process, as the photovoltaic panel 3 overturns counterclockwise around the steering rod 4, referring to Figure 4 and Figure 7 , the outer frame 2 drives the rotating roller 66 to revolve counterclockwise through the fixed plate 68, the rotating roller 66 pulls the elastic traction rope 67, so that the elastic traction rope 67 is stretched and deformed to the state as shown in Figure 9 , as the photovoltaic panel 3 is further overturned, referring to Figure 10 , the second plug plate 632 will be in contact with the arc-shaped stopper 11, and since the arc-shaped stopper 11 is fixed in position, the second plug plate 632 extends to the inner side of the outer frame 2, referring to Figure 6 , under the action of the linkage gear 635, the first plug plate 631 moves downward, the limiting of the reciprocating sliding block 62 is removed, the stretched elastic traction rope 67 needs to deform and reset, thereby driving the reciprocating sliding block 62 to move right along the side wall of the outer frame 2, thereby driving the rubber scraping strip 61 to move right, and the photovoltaic panel 3 is cleaned, until the reciprocating sliding block 62 slides to the rightmost side of the right-angle sliding groove 65, that is, after the photovoltaic panel 3 is turned from east to west for one day, the photovoltaic panel 3 is cleaned once.

[0058] In this embodiment, in order to enable the photovoltaic panel 3 to face the sun in the east on the second day, it is necessary to re-tilt the photovoltaic panel 3 to face the east, that is, the photovoltaic panel 3 is turned from Figure 9The position shown is transformed into... Figure 4 The location shown. During this process, refer to... Figure 9 The steering rod 4 drives the photovoltaic panel 3 to rotate clockwise. The steering rod 4, through the second gear 94, drives the first gear 92 to rotate counterclockwise. The first gear 92 drives the telescopic rod 93 to rotate counterclockwise.

This allows the rectangular push frame 96 to push the reciprocating slider 62 when it slides down or moves to the left along the side wall of the outer frame 2, causing the reciprocating slider 62 to slide downwards or to the left to reset. (Reference) Figure 8 When the photovoltaic panel 3 flips back to face east, the rectangular push frame 96 pushes the reciprocating slider 62 to the left end of the outer frame 2, as shown in the reference. Figure 5 and Figure 6 When the reciprocating slider 62 moves to the left to reset, it pushes the rounded end of the upper side of the first insert plate 631, causing the first insert plate 631 to slide inward to the outer frame 2 and compress the reset spring 633. When the reciprocating slider 62 slides to the left side of the first insert plate 631, the first insert plate 631 extends outward to the outer side of the outer frame 2 again under the action of the reset spring 633, thus limiting the reciprocating slider 62.

[0059] Working principle and usage process:

[0060] First, the multi-functional support frame 8 is installed in rows along a straight line at equal intervals in the work area. Then, the multi-functional support frame 8 is distributed in multiple rows according to work needs, so that the multi-functional support frame 8 is arranged in a matrix in the work area.

[0061] Next, the two fixed outer rings 822 are flipped open via the rotating shaft 823, and the steering rod 4 is placed inside the rotating semi-ring 821. The longer steering rod 4 will span several multi-functional support frames 8 simultaneously, and adjacent steering rods 4 can be connected by bolts. When the multi-functional support frames 8 are distributed in a matrix, or during the placement of the steering rods 4, the structure of the multi-functional support frames 8 can be adjusted. The support height of the rotating component 82 can be adjusted by the support column 81. By rotating the worm gear 86, the worm wheel 87 drives the support platform 89 to rotate, thereby adjusting the direction of the mounting holes of the rotating component 82. By rotating the lead screw 88, the chassis 85 can be translated, thereby moving the rotating component 82 along a direction perpendicular to the central axis of the steering rod 4, thus distributing multiple steering rods 4 along the same straight line.

[0062] After the plurality of steering rods 4 are arranged along the same straight line by the multifunctional support frame 8, the mounting frame 7 is installed on the steering rod 4, which is used for mounting the photovoltaic panel 3 with the outer frame 2, and the synchronous shaft 5 is fixedly installed at the same position of each row of steering rods 4, and the synchronous shaft 5 is located at the middle position of each row of steering rods 4, and the synchronous shafts 5 in the row are connected in series by a push-pull rod. In addition to the prior art, the push-pull rod is pushed and pulled by the external driving device, the push-pull rod rotates the synchronous shaft 5, and the rotation of the steering rod 4 is realized, which will not be described in detail here. The two fixed outer rings 822 are turned and closed and fixed by bolts, so that the steering rod 4 is clamped inside the two rotating half rings 821. When the external driving device synchronously pushes and pulls each synchronous shaft 5 through the push-pull rod, each synchronous shaft 5 drives each row of steering rods 4 to synchronously turn over, so that the mounting frame 7 drives the photovoltaic panel 3 to adjust the direction;

[0063] At the beginning or in the morning, the photovoltaic panel 3 is oriented to approach the east, and the inclined surface faces the sun. As the sun moves from east to west, the orientation of the photovoltaic panel 3 is turned from approaching the east to approaching the west. In this process, the photovoltaic panel 3 can be cleaned once by the rubber scraping strip 61 and the reciprocating slider 62 on the cleaning mechanism 6. When the orientation of the photovoltaic panel 3 returns to the east, the rubber scraping strip 61 and the reciprocating slider 62 after cleaning can be reset by the reset mechanism 9 to realize secondary cleaning. Specifically, refer to Figure 1 and Figure 4 At the beginning, the photovoltaic panel 3 is oriented to approach the east. As the sun moves from east to west, the steering rod 4 drives the mounting frame 7 to turn over by pushing the synchronous shaft 5, so that the photovoltaic panel 3 is oriented to approach the west (as shown in Figure 9 ). In this process, as the photovoltaic panel 3 turns over counterclockwise with the steering rod 4 as the axis, refer to Figure 4 and Figure 7 The outer frame 2 drives the rotating roller 66 to revolve counterclockwise by the fixed plate 68, the rotating roller 66 pulls the elastic traction rope 67, so that the elastic traction rope 67 is stretched and deformed to the state as shown in Figure 9 . As the photovoltaic panel 3 further turns over, refer to Figure 10 , the second plug plate 632 will be in contact with the arc-shaped resisting rod 11. Because the arc-shaped resisting rod 11 is fixed in position, the second plug plate 632 extends to the inside of the outer frame 2, refer to Figure 6 , under the action of the linkage gear 635, the first plug plate 631 moves downward, removing the limitation of the reciprocating slider 62, the stretched elastic traction rope 67 needs to deform and reset, thereby driving the reciprocating slider 62 to move right along the side wall of the outer frame 2, thereby driving the rubber scraping strip 61 to move right, wiping and cleaning the photovoltaic panel 3, until the reciprocating slider 62 slides to the rightmost side of the right-angle sliding groove 65, that is, after the orientation of the photovoltaic panel 3 is changed from east to west in a day, the photovoltaic panel 3 is self-cleaned once.

[0064] Afterwards, in order to enable the photovoltaic panel 3 to face the east sun of the next day, it is needed to re-invert the photovoltaic panel 3 to face the east, i.e. the photovoltaic panel 3 is transformed from the position shown in Figure 9 to the position shown in Figure 4 . In this process, referring to Figure 9 , the turning lever 4 drives the photovoltaic panel 3 to invert clockwise, the turning lever 4 drives the first gear 92 to rotate anticlockwise through the second gear 94, the first gear 92 drives the telescopic rod 93 to rotate anticlockwise, the telescopic rod 93 drives the rectangular push frame 96 to slide down along the side wall of the outer frame 2 through the connecting rod 95, and the T-shaped slider on the rectangular push frame 96 slides along the inner side of the T-shaped slide 64. It is needed to be explained that the reciprocating slider 62 at this time has been located at the right end of the outer frame 2 due to the traction of the elastic traction rope 67, i.e. the reciprocating slider 62 is in contact with the left end of the rectangular push frame 96, so that the rectangular push frame 96 can push the reciprocating slider 62 when it slides down or moves left along the side wall of the outer frame 2, and the reciprocating slider 62 slides down or left to reset. Referring to Figure 8 , when the photovoltaic panel 3 is re-inverted to face the east, the rectangular push frame 96 pushes the reciprocating slider 62 to the left end of the outer frame 2, referring to Figure 5 and Figure 6 , when the reciprocating slider 62 moves left to reset, it will push the upside of the first insertion plate 631, so that the first insertion plate 631 slides to the inner side of the outer frame 2, and the reset spring 633 is compressed. When the reciprocating slider 62 slides to the left side of the first insertion plate 631, the first insertion plate 631 re-extends to the outer side of the outer frame 2 under the action of the reset spring 633, and limits the reciprocating slider 62.
