[0037] like Figure 8 The limiting device 13 includes a supporting cavity 28, a second rack 29, a screw rod 30, a top bracket 31, a latch plate 32, a driving motor 33, a rear end bearing frame 34, a supporting base 35 and a transverse bracket 36.

The driving motor 33 is fixedly mounted at the right end center of the supporting cavity 28. The screw rod 30 is fixedly mounted on the output end of the driving motor 33. The top bracket 31 is fixedly mounted on the top front end of the supporting cavity 28. The second rack 29 is fixedly mounted on the top rear end of the top bracket 31.

The groove at both ends of the top inner part of the top bracket 31 is expanded outward at 30°, so that the contact sheet 7 and the sponge sheet 18 can pass through the inside of the groove.

[0038] The L-shaped card key 8 is slidably inserted into the inside of the horizontal bracket 36, the extended rear frame 27 is fixedly installed at the rear of the side end of the support base 35, the latch plate 32 is slidably inserted into the top of the support base 35, the displacement vertical frame 20 is threadedly sleeved on the screw rod 30, and the outer surface of the displacement vertical frame 20 is in contact with the inner wall of the support cavity 28, the support shaft 9 is rotatably installed in the extended rear frame 27 near the vertical frame 26, the bottom end of the lower cover plate 5 is hollow, and the contact piece 7 is slidably inserted into the inside of the lower cover plate 5, and there is an electrical connection between the contact piece 7 and the photovoltaic panel 4, and round holes are opened at both ends of the covering side plate 10. The top inner part of the top bracket 31 A groove is provided, and the sponge sheet 18 and the nylon brush 16 are aligned with the groove, a conductive sheet is installed in the groove, and the conductive sheet corresponds to the contact sheet 7 for power transmission; the first gear 14 is meshed with the second rack 29, and the rear end of the support cavity 28 is symmetrically fixed with a key, and a slot is provided at the rear end of the rear end bearing frame 34, and a card slot is provided inside the transverse bracket 36, the second gear 24 is meshed with the first rack 23, and the two sides of the first rack 23 are in contact with the inner walls of the two supporting vertical frames 19, and the two ends of the inner groove at the top of the top bracket 31 are both inclined at 30°, and a square hole is provided inside the top of the supporting base 35.

[0039] The working principle of Example 1 is as follows: when in use, the support base 35 is first moved and placed in the designated installation area, and then the external bolts are passed through the installation holes at the bottom ends of the support bases 35, so that the support bases 35 can be installed on the base platform on the external ground. Subsequently, the support cavity 28 can be inserted into the interior of the rear end support frame 34. At the same time, when the support cavity 28 is inserted into the interior of the rear end support frame 34, the latch plate 32 can be driven to be inserted into the square hole inside the top end of the support base 35, so that the integrity of the rear end of the support base 35 can be improved. At the same time, the key at the rear end of the support cavity 28 can be inserted into the slot at the rear end of the rear end support frame 34, so that the support cavity 28 can be prevented from being skewed. Subsequently, the photovoltaic panel 4 can be moved as a whole to coincide with the horizontal bracket. 36 is aligned, and then the L-shaped card key 8 is slidably inserted into the card slot inside the horizontal bracket 36, so that the photovoltaic panel 4 can be supported for temporary placement. Subsequently, the driving motor 33 can be started to drive the screw rod 30 to rotate clockwise, thereby driving the displacement vertical frame 20 to move toward one end close to the photovoltaic panel 4. When the limiting rod 15 moves to contact the photovoltaic panel 4, the limiting rod 15 can be rotated to the end away from the limiting side plate 21 through the blocking of the photovoltaic panel 4. At the same time, when the limiting rod 15 is rotating, it can drive the first rack 23 to move toward the end close to the limiting side plate 21, so that it is convenient for the limiting rod 15 to pass through the photovoltaic panel 4. At this time, the first rack 23 is always active and abuts against the top of the displacement vertical frame 20; when the limiting rod 15 completely passes the bottom end of the photovoltaic panel 4, the limiting rod 15 will lose the blocking of the photovoltaic panel 4, and the elasticity of the second spring 22 will pull the first rack 23 to reset, and the first rack 23 will fit with the inner walls of the two supporting vertical frames 19, so that the first rack 23 can be guaranteed to be in a straight line position. When the first rack 23 is reset, the second gear 24 and the limiting rod 15 can be driven to reset at the same time, so that the limiting rod 15 is rotated to be placed in a vertical posture when it contacts the limiting side plate 21. Subsequently, the driving motor 33 can be started again to drive the screw rod 30 to rotate counterclockwise, so that the displacement vertical frame 20 can be displaced toward one end of the driving motor 33. At this time, when the limiting rod 15 contacts the photovoltaic panel 4, the limiting side plate 21 is restricted to prevent the limiting rod 15 from rotating toward the end close to the limiting side plate 21, thereby displacing the vertical frame 20. When displacing, the photovoltaic panel 4 can be driven to one end position close to the driving motor 33. At the same time, when the displacement vertical frame 20 is displaced, the sponge sheet 18 can be driven to pass through the groove inside the top of the top bracket 31, so that the dust and impurities accumulated in the groove can be swept out; and when the displacement vertical frame 20 is displaced, the first gear 14 can also be driven to move on the second rack 29, so that the first gear 14 can drive the nylon brush 16 to rotate at the same time, so that the nylon brush 16 and the sponge sheet 18 can cooperate to remove the impurities inside the top of the top bracket 31; then, when the photovoltaic panel 4 is pushed to the limit position by the limiting rod 15, the L-shaped card key 8 can be displaced to the limit position in the card slot inside the horizontal bracket 36, so that the L-shaped card key 8 can be prevented from falling off;At the same time, when the photovoltaic panel 4 moves to the limit position, the contact piece 7 can be driven to move accurately to the groove inside the top of the top bracket 31, so that the contact piece 7 can contact the conductive piece in the groove, so that the photovoltaic panel 4 can output energy through the contact piece 7 and the conductive piece. By repeating the above steps, multiple photovoltaic panels 4 can be pushed and positioned. After the last photovoltaic panel 4 is installed, the limiting rod 15 can be located on the left side of the photovoltaic panel 4 on the leftmost side of the horizontal bracket 36, so as to prevent the photovoltaic panel 4 installed and placed from sliding again. Subsequently, the covering side panel 10 can be flipped upward to a vertical state, so that the circular holes at both ends of the covering side panel 10 can be horizontally aligned with the positioning bolts 25. At this time, the positioning bolts 25 can be screwed and rotated into the circular holes of the covering side panel 10, so that the covering side panel 10 can be limited and positioned to prevent the covering side panel 10 from rotating again, so that the covering side panel 10 can be located at the rear end of the supporting foot 35 to protect the driving motor 33 and the screw rod 30, and the work is completed. ;

[0040] Example 2

[0041] On the basis of Example 1, Fig. 9 As shown, the photovoltaic panel 4 further includes an energy absorbing bracket 37 and a plastic pad 38 . The energy absorbing bracket 37 is symmetrically fixedly installed on both sides of the photovoltaic panel 4 , and the plastic pad 38 is symmetrically fixedly installed on the side end of the energy absorbing bracket 37 away from the photovoltaic panel 4 .

[0042] When implementing this embodiment, the plastic pad 38 and the energy absorbing bracket 37 are located on both sides of the photovoltaic panel 4, so that when the two photovoltaic panels 4 contact each other, the plastic pads 38 can contact each other, thereby preventing a rigid collision between the two photovoltaic panels 4 and avoiding damage to the photovoltaic panels 4, thereby greatly improving the safety and stability of the photovoltaic panels 4 during installation.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
