Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to a bearing assembly and a photovoltaic tracking support. Background Technology

[0002] With the world's energy resources becoming increasingly depleted and the development and utilization of renewable energy deepening, the comprehensive and efficient use of solar energy has become a goal pursued by industry professionals. Photovoltaic power generation devices use solar panels to receive sunlight and convert light energy into electrical energy. The power generation capacity of a solar panel is directly proportional to the intensity of the sunlight it receives, and the power generation capacity is strongest when the incident sunlight is perpendicular to the solar panel.

[0003] Photovoltaic (PV) mounting systems can be categorized by function into fixed systems and tracking systems. Tracking systems primarily utilize single-axis tracking systems, which employ astronomical algorithms to adjust the tilt angle of solar panels in real time, enabling them to continuously track the sun's trajectory. Currently, the bearing components of PV tracking systems on the market typically use cylindrical or spherical shapes. Without restraint mechanisms, these cylindrical or spherical bearings can shift axially, preventing the tracking system from functioning properly.

[0036] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0037] like Figures 1-3 As shown, in a first aspect, embodiments of this application may provide a bearing assembly for a photovoltaic tracking bracket, which may include:

[0038] Bearing housing 1, used for mounting on the column 3 of the photovoltaic tracking bracket;

[0039] Bearing 2 is rotatably mounted in bearing housing 1, and bearing 2 and bearing housing 1 are coaxially arranged; bearing housing 1 has a snap-fit ​​part on the side facing bearing 2, and bearing 2 has a snap-fit ​​groove 21 adapted to the snap-fit ​​part on the side facing bearing housing 1, and the snap-fit ​​groove 21 is opened along the circumferential direction of bearing 2.

[0040] Among them, bearing 2 is used to fix the main beam 4; during the rotation of bearing 2, the snap-fit ​​part slides in the snap-fit ​​groove 21.

[0041] In this embodiment, when the bearing 2 rotates on the bearing housing 1, the locking part slides in the locking groove 21, thereby limiting the bearing 2 to move in the axial direction, solving the problem of the bearing 2 moving out of the axial direction; in addition, the bearing assembly of this application has better structural mechanical performance and reasonable design, ensuring the stability and reliability of the rotation of the main beam 4; and the bearing assembly has fewer types of installation parts, reducing the installation difficulty, and also facilitating the batch processing of parts, making it more economical.

[0042] It should be noted that, in this embodiment, the structure of the snap-fit ​​part is not limited, and can be a rod-shaped structure, a plate-shaped structure, or a protruding structure. When the snap-fit ​​part is located in the snap-fit ​​groove 21, when the bearing 2 rotates on the bearing seat 1, the snap-fit ​​part is always in the snap-fit ​​groove 21 and slides relative to the snap-fit ​​groove 21.

[0043] In an optional embodiment, the bearing housing 1 includes a bearing base 13 and a bearing end cap 20, which together form a mounting hole 14; the snap-fit ​​portion includes a first snap-fit ​​protrusion 11 and a second snap-fit ​​protrusion 12, the first snap-fit ​​protrusion 11 being located on the side of the bearing base 13 facing the bearing 2, and the second snap-fit ​​protrusion 12 being located on the side of the bearing end cap 20 facing the bearing 2; wherein the bearing 2 is rotatably disposed within the mounting hole 14; the bearing base 13 and the bearing end cap 20 are detachably connected by a connector 15.

[0044] In this embodiment, the bearing housing 1 includes a bearing base 13 and a bearing end cap 20, which are separate designs. This improves the installation efficiency and portability of the bearing 2 mounted on the bearing housing 1. Furthermore, since the bearing base 13 and the bearing end cap 20 are detachably connected by a connector 15, they can be removed and replaced if one component is damaged, thus extending the service life of the bearing assembly and reducing operating costs. In this embodiment, the connector 15 can be a bolt, nut, or screw. In this embodiment, the first snap-fit ​​protrusion 11 is integrally formed with the bearing base 13, and the second snap-fit ​​protrusion 12 is integrally formed with the bearing end cap 20, facilitating production.

[0045] In an optional embodiment, a first mounting plate 16 and a second mounting plate 17 are arranged side by side on the side of the bearing base 13 away from the bearing 2, and a part of the column 3 is located between the first mounting plate 16 and the second mounting plate 17; the column 3 is connected to the first mounting plate 16 and the second mounting plate 17 by a fastener 18.

[0046] In this embodiment, the first mounting plate 16 and the second mounting plate 17 can be integrally formed with the bearing base 13, which effectively improves the installation efficiency of the bearing base 1 on the column 3; the first mounting plate 16 and the second mounting plate 17 are integrally stamped with the bearing base 13, which is convenient for mass production; and since a part of the column 3 (web plate) is located between the first mounting plate 16 and the second mounting plate 17, the connection between the two is more solid, which improves the connection stability between the bearing base 1 and the column 3.

[0047] In an optional embodiment, the first mounting plate 16 and the second mounting plate 17 are each provided with a through adjustment hole 31, and the fastener 18 fixes the first mounting plate 16, the second mounting plate 17 and the column 3 through the adjustment hole 31; wherein, the opening direction of the adjustment hole 31 is perpendicular to the length direction of the column 3.

[0048] In this embodiment, since the opening direction of the adjustment hole 31 is perpendicular to the length direction of the column 3, the installation position of the bearing seat 1 can be adjusted along the direction perpendicular to the column 3 (horizontal direction), and then fixed by the fastener 18. In addition, in this embodiment, the fastener 18 can be a bolt, nut, or screw.

[0049] In an optional embodiment, the first snap-fit ​​protrusion 11 and the second snap-fit ​​protrusion 12 are respectively and independently arc-shaped protrusions; the snap-fit ​​groove 21 is an arc-shaped groove, and the arc-shaped groove is adapted to the arc-shaped protrusion.

[0050] In this embodiment, since the arc-shaped groove and the arc-shaped protrusion are adapted to each other, the relative friction between them is extremely small. While improving the stability and reliability of the bearing 2 rotating on the bearing seat 1, it can also play a role in removing sand and dust, reducing the accumulation of sand and dust in the bearing seat 1, reducing the wear of sand and dust on the bearing assembly, and improving the service life of the bearing assembly.

[0051] It should be noted that the bearing assembly of this application embodiment can be applied to windy and sandy areas. Since the arc-shaped protrusion is set on the inner side of the bearing seat 1, the structure of the protrusion can reduce the accumulation of sand and dust, there is no place to store sand and dust, and when the arc-shaped protrusion rotates in the arc-shaped groove, it can also remove excess sand and dust, reducing the impact of sand and dust on the rotational stability of the bearing assembly.

[0052] In an optional embodiment, the distance between the top of the first snap-fit ​​protrusion 11 and the inner side of the bearing base 13 is greater than 2cm; the distance between the top of the second snap-fit ​​protrusion 12 and the inner side of the bearing end cap 20 is greater than 2cm.

[0053] In this embodiment, the distance between the top of the first snap-fit ​​protrusion 11 and the inner side of the bearing base 13 (i.e., the thickness of the first snap-fit ​​protrusion 11) is greater than 2cm, which can increase the thickness of the first snap-fit ​​protrusion 11 entering the snap-fit ​​groove 21, increase the contact area between the first snap-fit ​​protrusion 11 and the snap-fit ​​groove 21, and further improve the rotational stability and reliability of the bearing base 13 and the bearing 2; the distance between the top of the second snap-fit ​​protrusion 12 and the inner side of the bearing base 13 (i.e., the thickness of the second snap-fit ​​protrusion 12) is greater than 2cm, which can increase the thickness of the second snap-fit ​​protrusion 12 entering the snap-fit ​​groove 21, increase the contact area between the second snap-fit ​​protrusion 12 and the snap-fit ​​groove 21, and further improve the rotational stability and reliability of the bearing end cover 20 and the bearing 2.

[0054] In an optional embodiment, the bearing base 13 and the bearing end cap 20 each have a rounded corner 19 on both sides, independently.

[0055] In this embodiment, the opening of the fillet 19 can improve the efficiency of dust discharge and reduce the wear of dust on the bearing assembly.

[0056] In an optional embodiment, the bearing 2 includes a first bearing 22 and a second bearing 23, which together form a insertion hole 24; a portion of the snap-fit ​​groove 21 is located on the first bearing 22, and the other portion is located on the second bearing 23; wherein, the main beam 4 is disposed in the insertion hole 24, and the shape of the insertion hole 24 is adapted to the shape of the main beam 4.

[0057] In this embodiment, the bearing 2 adopts a split design, which makes it easy to insert the main beam 4 into the insertion hole 24, thereby improving the installation efficiency of the bearing assembly when installing the main beam 4.

[0058] In an optional embodiment, the main beam 4 includes one of a square tube, a hexagonal tube, an octagonal tube, and a round tube.

[0059] In this embodiment, since the shape of the insertion hole 24 is adapted to the shape of the main beam 4, the shape of the main beam 4 is not limited, which increases the types of main beam 4 that can be installed on the bearing assembly, thereby increasing the applicability of the bearing assembly.

[0060] Secondly, embodiments of this application may provide a photovoltaic tracking bracket, which may include a column 3 and a bearing assembly of the photovoltaic tracking bracket as described in any of the above embodiments, wherein the bearing 2 is rotatably mounted on the column 3 via a bearing seat 1.
