[0044] Solar photovoltaic power generation is a new green and environmentally friendly way of power generation. The photovoltaic tracking bracket system is an important support system for photovoltaic components in solar power stations, which can effectively increase the power generation of components.

[0045] At present, the main beams of photovoltaic tracking brackets on the market are mostly square, hexagonal, octagonal, round, etc. Among them, the round tube main beam has great advantages in torsion resistance when the tracking bracket is in working state, but the round tube main beam cannot limit the relative rotation between itself and the bearing, which easily leads to increased wear of the bearing.

[0046] Reference Figures 1 to 3 , Figures 1 to 3 The structure of the bearing system 10 proposed in an embodiment of the present application is shown. An embodiment of the present application proposes a bearing system 10, which includes: a bearing base 11, a bearing 12, a round tube beam column 13 and at least one stopper 14, the bearing 12 includes a bearing inner ring 121 and a bearing outer ring 122 in rolling connection, the bearing outer ring 122 is installed on the bearing base 11, the inner surface of the bearing inner ring 121 is an arc surface, and the bearing inner ring 121 is provided with at least one opening facing inward; the round tube beam column 13 is penetrated by the bearing inner ring 121; the stopper 14 is fixed to the surface of the round tube beam column 13, and cooperates with the opening to limit the relative sliding between the round tube beam column 13 and the bearing inner ring 121.

[0047] Reference Figures 4 to 6 , Figures 4 to 6The structure of the bearing base 11 proposed in the embodiment of the present application is shown. The bearing base 11 serves as a fixed base of the bearing system 10 and is usually made of a strong and corrosion-resistant material. The shape and size of the bearing base 11 are designed according to actual needs to ensure the stability and safety of the bearing. The material of the bearing base 11 can be selected according to the actual application scenario and is not limited here. For example, the bearing base 11 can be made of materials such as cast iron or stainless steel.

[0048] Reference Figures 7 to 11 , Figures 7 to 11 The structure of the bearing 12 proposed in the embodiment of the present application is shown. The bearing 12 includes a bearing inner ring 121 and a bearing outer ring 122. The bearing outer ring 122 is mounted on the bearing base 11 and fixed by bolts or other fasteners. The bearing inner ring 121 and the bearing outer ring 122 can be rolled together by balls. When the bearing outer ring 122 is fixedly connected to the bearing base 11, the bearing inner ring 121 can rotate relative to the bearing outer ring 122. The material of the bearing can be the same as that of the bearing base 11, or it can be different from the bearing base 11. The material of the bearing can also be selected according to the actual application scenario, which is not limited here. For example, the bearing base 11 can be made of materials such as cast iron or stainless steel.

[0049] The inner surface of the bearing inner ring 121 is an arc surface, which matches the outer surface of the round tube beam column 13 to achieve rolling connection.

[0050] The circular tube beam column 13 is mainly used to support photovoltaic modules, photovoltaic tracking controllers, etc. The outer surface of the circular tube beam column 13 matches the arc surface of the bearing inner ring 121, and the circular tube beam column 13 can rotate according to the instructions of the controller, thereby ensuring that the photovoltaic module can always be aligned with the sun to maximize the reception of solar energy.

[0051] The stopper 14 is fixed to the surface of the circular tube beam column 13 and cooperates with the opening of the bearing inner ring 121. When the circular tube beam column 13 rotates circumferentially in the bearing inner ring 121, the stopper 14 interacts with the opening of the bearing inner ring 121, thereby limiting the relative sliding between the circular tube beam column 13 and the bearing inner ring 121 and reducing the friction between the beam column and the bearing.

[0052] The stopper 14 is usually made of wear-resistant and corrosion-resistant materials. The specific material of the stopper 14 can be selected according to the actual application scenario and is not limited here. For example, the stopper 14 can be made of chrome steel, carbon steel or stainless steel.

[0053] According to the bearing system 10 of the present application, the limit member 14 is fixed to the surface of the circular tube beam column 13 and cooperates with the opening on the bearing inner ring 121. When the circular tube beam column 13 rotates in the circumferential direction, the limit member 14 drives the bearing inner ring 121 to rotate, which can ensure the synchronous rotation of the circular tube beam column 13 and the bearing, thereby effectively limiting the relative rotation between the circular tube beam column 13 and the bearing and reducing the friction between the beam column and the bearing.

[0054] Reference Figure 12 to Figure 14 , Figure 12 to Figure 14 The structure of the stopper 14 proposed in the embodiment of the present application is shown. In some embodiments, the stopper 14 includes a connecting portion 141 and an extending portion 142, the connecting portion 141 is detachably connected to the surface of the circular tube beam column 13, and the extending portion 142 extends from the connecting portion 141 in a direction away from the circular tube beam column 13 to extend into and stop at the opening.

[0055] The connection part 141 of the limit member 14 is detachably connected to the surface of the circular tube beam column 13, and its specific connection method can be selected according to the actual application scenario and is not limited here. For example, the connection part 141 of the limit member 14 and the surface of the circular tube beam column 13 can be detachably connected by bolts, clips or threads.

[0056] The extension portion 142 of the limiting member 14 extends from the connecting portion 141 in a direction away from the round tube beam column 13 , and is mainly used to extend into the opening of the bearing inner ring 121 and stop at the opening to play a limiting role.

[0057] The connecting portion 141 and the extending portion 142 may be made of the same material or different materials. The materials of the connecting portion 141 and the extending portion 142 may be selected according to the actual application scenario and are not limited here. For example, the connecting portion 141 and the extending portion 142 may both be made of stainless steel.

[0058] The length and shape of the connecting portion 141 and the extending portion 142 can be selected according to the actual application scenario, and are not limited here. For example, the connecting portion 141 can be in a long strip shape, and the extending portion 142 can also be in a long strip shape. The length of the extending portion 142 can be the same as the length of the connecting portion 141, or it can be different from the length of the connecting portion 141.

[0059] In some embodiments, the connection portion 141 is in an elongated strip shape and extends along the axial direction of the circular tube beam column 13 . The extension portion 142 includes two ribs formed on both sides of the connection portion 141 , and the ribs extend along the axial direction of the circular tube beam column 13 .

[0060] The connecting portion 141 is in the shape of a long strip, which can ensure that the stopper 14 can also contact the bearing inner ring 121 when there is an installation error, making the present solution more applicable. The length of the connecting portion 141 can be selected according to the actual application scenario, which is not limited here. For example, the length of the connecting portion 141 can be 15 cm.

[0061] In some embodiments, the surface of the connection part 141 that contacts the circular tube beam column 13 is an arc surface, the connection part 141 is provided with a mounting hole 143, the circular tube beam column 13 is provided with a pre-installed hole, and the mounting hole 143 and the pre-installed hole are connected by rivets.

[0062] The side of the connection portion 141 that contacts the circular tube beam 13 is an arc surface, so that the limiting member 14 fits better with the outer surface of the circular tube beam 13 and avoids friction between the limiting member 14 and the surface of the circular tube beam 13.

[0063] The connection part 141 is provided with an installation hole 143 adapted to the pre-installed hole on the surface of the circular tube beam column 13, which can realize the connection between the limiter 14 and the circular tube beam column 13 before the circular tube beam column 13 is passed through the bearing inner ring 121, making the installation more convenient.

[0064] In some embodiments, the connecting portion 141 and the extending portion 142 are integrally formed by stamping.

[0065] The stopper 14 produced by the stamping process has a high degree of reliability and consistency. The precision and stability of the mold ensure that the quality of each stopper 14 is consistent, and high-speed, large-scale production can be achieved. In addition, the connecting portion 141 and the extension portion 142 have a simple structure. Through one-time stamping, the welding process of the connecting portion 141 and the extension portion 142 is reduced, and the steps of processing and assembling multiple parts in traditional processing are avoided, thereby reducing production costs. Thereby improving production efficiency, the use of materials can also be more economical and economical.

[0066] In some embodiments, in the axial direction of the circular tube beam column 13 , the lengths of the connecting portion 141 and the extending portion 142 are both greater than the length of the bearing 12 , and are both symmetrically arranged relative to the bearing 12 .

[0067] The lengths of the connecting portion 141 and the extending portion 142 in the axial direction of the circular tube beam column 13 are both greater than the length of the bearing 12, which can ensure that the stopper 14 can also contact the inner ring 121 of the bearing when there is an installation error, making the application range of this solution wider. The connecting portion 141 and the extending portion 142 are symmetrically arranged relative to the bearing 12, which can make the bearing 12 more evenly stressed, ensuring that when the circular tube beam column 13 rotates in the circumferential direction, the stopper 14 drives the inner ring 121 of the bearing to rotate synchronously.

[0068] The lengths of the connecting portion 141 and the extending portion 142 can be selected according to actual application scenarios and are not limited here. For example, the lengths of the connecting portion 141 and the extending portion 142 can both be 16 cm.

[0069] In some embodiments, the inner surface of the bearing inner ring 121 is a hollow structure.

[0070] Compared with a solid structure, the hollow structure is lighter, which is beneficial to increasing the rotation speed of the bearing 12. In addition, the inner surface of the bearing inner ring 121 adopts a hollow structure to make material use more efficient, reduce material waste, and thus reduce manufacturing costs.

[0071] In some embodiments, there are multiple limiters 14 , and each limiter 14 is evenly arranged along the circumference of the circular tube beam column 13 .

[0072] The multiple limiters 14 can better realize the synchronous rotation of the circular tube beam column 13 and the bearing 12, ensuring that the bearing 12 is supported and limited in multiple directions, thereby improving the stability of the entire structure. The limiters 14 are evenly arranged along the circumference of the circular tube beam column 13, so that the bearing 12 is more evenly stressed. In addition, the uniform arrangement of the multiple limiters 14 can disperse the external force to each limiter 14, reduce the stress on a single limiter 14, and reduce the risk of damage caused by stress concentration. This way of dispersing the force can extend the service life of the limiters 14 and the circular tube beam column 13.

[0073] In some embodiments, the bearing system 10 further includes a column 15 and a U-shaped bearing support 16. The U-shaped bearing support 16 has a bottom plate and two side plates formed on opposite sides of the bottom plate, and the side plates are fixedly connected to the column 15; wherein the bearing base 11 is fixed to the bottom plate.

[0074] The column 15 is the main supporting part of the bearing system 10 and is responsible for bearing the weight and transmitted force of the bearing and the components above it.

[0075] The design of the U-shaped bearing support 16 makes the installation of the bearing base 11 simple and convenient. By fixing it to the bottom plate, the installation and positioning of the bearing can be completed quickly.

[0076] The side plates of the U-shaped bearing support 16 are formed on opposite sides of the bottom plate and are usually fixedly connected to the column 15 by bolts, welding or other means to ensure the stability and rigidity of the U-shaped bearing support 16 .

[0077] An embodiment of the present application provides a photovoltaic tracking bracket, which includes the aforementioned bearing system 10 , and the photovoltaic tracking bracket includes at least one circular tube beam column 13 .

[0078] The circular tube beam column 13 is usually passed through the aforementioned bearing system 10. Photovoltaic panels and photovoltaic tracking controllers are fixed on the cylindrical main beam. The cylindrical main beam rotates circumferentially according to the signal transmitted by the photovoltaic tracking controller so that the photovoltaic components follow the movement of sunlight, thereby improving the power generation efficiency of the photovoltaic panels.

[0079] The specific structure of the bearing system 10 may refer to the aforementioned embodiment and will not be described in detail here.

[0080] According to the photovoltaic tracking bracket of the present application, the limit member 14 is fixed to the surface of the circular tube beam column 13 and cooperates with the opening on the inner ring 121 of the bearing. When the circular tube beam column 13 rotates in the circumferential direction, the limit member 14 drives the inner ring 121 of the bearing to rotate, which can ensure the synchronous rotation of the circular tube beam column 13 and the bearing, thereby effectively limiting the relative rotation between the circular tube beam column 13 and the bearing and reducing the friction between the beam column and the bearing.
