Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] As Figures 1 to 6 shown, the present invention provides a slewing bearing for a photovoltaic bracket, including:

[0032] A circular ring 1, and a support ring 2 is fixedly installed on the right side of the circular ring 1;

[0033] A driving mechanism, which is arranged inside the circular ring 1;

[0034] A clamping mechanism, which is arranged on the right side of the circular ring 1;

[0035] Among them, the clamping mechanism includes a circular ring 3. The left side of the circular ring 3 is movably connected to the right side of the circular ring 1. The outer surface of the left end of the circular ring 3 is movably sleeved inside the support ring 2. The left side inside the circular ring 3 is fixedly sleeved with a first toothed ring 4. The right side inside the circular ring 3 is fixedly sleeved with a circular plate 5. An arc-shaped groove 6 is formed on the outer surface of the circular plate 5. A circular shaft 7 is movably connected inside the arc-shaped groove 6. The left end of the circular shaft 7 is fixedly sleeved with a moving plate 8. The right side of the moving plate 8 is movably connected to the left side of the circular plate 5. The other end of the moving plate 8 is fixedly installed with a first clamping block 9. The outer surface of the moving plate 8 is movably connected to a limiting block 10. One end of the limiting block 10 is movably connected to the left side of the circular plate 5. The other end of the limiting block 10 is fixedly connected to the inside of the circular ring 1.

[0036] Due to the design of the support ring 2, the circular ring 3 can only rotate along its interior. When the circular ring 3 drives the circular plate 5 to rotate, at this time, the interior of the arc-shaped groove 6 will squeeze and push the circular shaft 7, causing the circular shaft 7 to drive the moving plate 8 to move. Due to the limitation of the four limit blocks 10, at this time, the four moving plates 8 will respectively drive the four first clamping blocks 9 to move inward. At this time, the four first clamping blocks 9 will clamp the cross bar at the bottom of the photovoltaic panel during the inward movement, thus achieving the effect of connecting with the photovoltaic panel.

[0037] Among them, the driving mechanism includes:

[0038] A driving motor 11, the outer surface of the driving motor 11 is fixedly connected to the bottom end inside the circular ring 1, and the other end of the output shaft of the driving motor 11 is fixedly sleeved with a rotating shaft 12;

[0039] A first gear 13, the interior of the first gear 13 is fixedly sleeved with the outer surface of the rotating shaft 12, and the outer surface of the first gear 13 is meshed and connected with the interior of the first toothed ring 4.

[0040] When the driving motor 11 operates, at this time, the rotating shaft 12 will drive the first gear 13 to rotate. Since the outer surface of the first gear 13 is meshed and connected with the first toothed ring 4, at this time, the first gear 13 will drive the circular ring 3 to rotate through the first toothed ring 4.

[0041] Among them, the outer surface of the circular ring 1 is movably connected with a fixed plate 30. The interior of the top end of the fixed plate 30 is movably connected with a rotating ring 31, and the interior of the rotating ring 31 is fixedly sleeved with the outer surface of the circular ring 1.

[0042] Due to the design of the fixed plate 30, the rotating ring 31 can only rotate along the interior of the fixed plate 30.

[0043] Among them, a power motor 14 is fixedly installed on the right side of the fixed plate 30. The other end of the output shaft of the power motor 14 is fixedly sleeved with a rotating shaft 15, and the outer surface of the rotating shaft 15 is movably sleeved with the interior of the fixed plate 30.

[0044] When the power motor 14 operates, at this time, the rotating shaft 15 will rotate.

[0045] Among them, the other end of the rotating shaft 15 is fixedly sleeved with a second gear 16. The outer surface of the second gear 16 is meshed and connected with a second toothed ring 17. The interior of the second toothed ring 17 is fixedly sleeved with a rotating ring 18, and the right side of the rotating ring 18 is fixedly connected with the left side of the circular ring 1.

[0046] When the rotating shaft 15 rotates, the second gear 16 will rotate driven by the rotating shaft 15 at this time. Since the outer surface of the second gear 16 is meshed and connected with the second toothed ring 17, when the second gear 16 rotates, it will drive the rotating ring 18 to rotate through the second toothed ring 17. Immediately afterwards, the rotating ring 18 will drive the entire ring 1 to rotate. Due to the design of the fixed plate 30 and the rotating ring 31, the ring 1 will rotate along the outer surface of the top end of the fixed plate 30 at this time.

[0047] Among them, a bottom plate 19 is fixedly installed at the bottom end of the fixed plate 30. A long groove 20 is opened at the center of the bottom end of the bottom plate 19, and short grooves 21 are opened on both the front and rear sides of the bottom end of the bottom plate 19.

[0048] Due to the design of the long groove 20, the object located inside it will be limited, so that it can only move left and right. Due to the design of the two short grooves 21, the object located inside them will be limited, so that it can only move back and forth.

[0049] Among them, a dual-axis motor 22 is fixedly installed inside the long groove 20, and the other end of the output shaft of the dual-axis motor 22 is fixedly sleeved with a screw rod 23.

[0050] When the dual-axis motor 22 operates, the two screw rods 23 will rotate at this time.

[0051] Among them, the outer surface of the screw rod 23 is threadedly sleeved with a movable block 24, and the outer surface of the movable block 24 is movably connected with the inside of the long groove 20.

[0052] Since the outer surfaces of the two movable blocks 24 are both movably connected with the inside of the long groove 20, when the two screw rods 23 rotate, the two movable blocks 24 will move away from each other along the inside of the long groove 20 at this time.

[0053] Among them, a short shaft 25 is fixedly installed at the bottom end of the movable block 24. The outer surface of the short shaft 25 is movably sleeved with a moving rod 26. The other end of the moving rod 26 is hinged with a hinge block 27. The other end of the hinge block 27 is fixedly installed with a second clamping block 28, and the top end of the second clamping block 28 is movably connected with the bottom end of the bottom plate 19.

[0054] When the two movable blocks 24 move away from each other, the two movable blocks 24 will drive the four moving rods 26 to move through the four short shafts 25 at this time. Immediately afterwards, the four moving rods 26 will drive the four second clamping blocks 28 to move through the four hinge blocks 27.

[0055] Among them, a moving block 29 is fixedly installed at the top end of the second clamping block 28, and the outer surface of the moving block 29 is movably connected with the inside of the short groove 21.

[0056] When the two second clamping blocks 28 move, they will drive the two moving blocks 29 to move respectively. Due to the design of the two short grooves 21, the two second clamping blocks 28 will drive the two moving blocks 29 to move towards each other. Subsequently, the two second clamping blocks 28 will clamp the photovoltaic bracket during the inward movement, thus achieving the function of connecting with the photovoltaic bracket.

[0057] The working principle and usage process of the present utility model:

[0058] First, the operator inserts the bottom crossbar of the photovoltaic panel into the inside of the whole circular ring 1. Subsequently, the operator starts the driving motor 11. At this time, the rotating shaft 12 will drive the first gear 13 to rotate. Since the outer surface of the first gear 13 is meshed and connected with the inside of the first toothed ring 4, at this time, the first gear 13 will drive the first toothed ring 4 to rotate. Immediately afterwards, the first toothed ring 4 will drive the circular ring 3 to rotate along the inside of the support ring 2. At the same time, the circular plate 5 will be driven by the circular ring 3 to rotate. During this process, the inside of the four arc-shaped grooves 6 will squeeze and push the outer surfaces of the four circular shafts 7, so that the four circular shafts 7 drive the four moving plates 8 to move. Due to the design of the four limiting blocks 10, the movement of the four moving plates 8 will be limited, so that the four moving plates 8 can only move along the inside of the four limiting blocks 10. At this time, the four moving plates 8 will drive the four first clamping blocks 9 to move inwards along the inside of the four limiting blocks 10. Subsequently, the four first clamping blocks 9 will clamp the crossbar during the inward movement. At this time, the crossbar will be fixed inside the whole circular ring 1, thus realizing the function of being able to install photovoltaic panels of different sizes.

[0059] Then the operator starts the double-axis motor 22, and the two screws 23 will rotate at the same time. Since the outer surfaces of the two screws 23 are respectively sleeved with the internal threads of the two movable blocks 24, when the two screws 23 rotate, they will drive the two movable blocks 24 to move respectively. Since the outer surfaces of the two movable blocks 24 are movably connected with the inside of the long groove 20, the two movable blocks 24 will move away from each other along the inside of the long groove 20 driven by the two screws 23. At the same time, the two movable blocks 24 will drive the four short shafts 25 to move away from each other, and then the four short shafts 25 will respectively drive the four moving rods 26 to move, and then the other ends of the four moving rods 26 will respectively drive the four hinged blocks 27 to move. At this time, the four hinged blocks 27 will be driven by the two second clamping blocks 28 The two moving blocks 29 move, and due to the design of the two short grooves 21, the movement of the two moving blocks 29 will be limited so that they can only move forward and backward. At this time, the two second clamping blocks 28 will drive the two moving blocks 29 to move toward each other, and then the two second clamping blocks 28 will clamp the photovoltaic bracket during the movement toward each other, thereby realizing the function of rapid disassembly and assembly of the slewing bearing and the photovoltaic bracket. Then the operator starts the power motor 14, and the rotating shaft 15 will drive the second gear 16 to rotate. Since the outer surface of the second gear 16 is meshed with the second gear ring 17, the second gear 16 will drive the rotating ring 18 to rotate through the second gear ring 17, and then the rotating ring 18 will drive the ring 1 to rotate as a whole, so that the orientation angle of the photovoltaic panel can be adjusted according to the direct angle of the sun.
