[0002] As photovoltaic power generation projects become increasingly popular, photovoltaic trackers, which automatically rotate to track sunlight, are gaining increasing attention. When installing a photovoltaic tracker, a rotating device that can adjust the photovoltaic modules is required, and bearing seats play a very important role in this rotating device.

[0003] Currently, commonly used bearing seats are mainly composed of a welded combination of round tubes, stiffening plates and base plates. There are strict requirements on the welding process during production, which is prone to welding deformation. It is also easy to deform due to pressure during transportation, and the roundness of the bearing seat cannot be guaranteed, resulting in difficulties in installing the bearing seat and the main shaft. In addition, the one-piece round tube bearing seat is not convenient for the installation of the bracket. The heavy main shaft needs to be lifted and inserted from the side on site, which requires high construction intensity. In response to the above defects, this application is proposed.

[0025] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0026] Example 1:

[0027] A bearing seat, such as Figure 1 , including a base 1 and a clamp assembly.

[0028] The base 1 is made of sheet metal U-shaped bending, and the upper flange is stretched to form a mounting surface 11 with an arc. The bottom and side surfaces are provided with mounting holes, which can be fixed to the column of the tracking bracket.

[0029] The clamp assembly includes two groups of clamp units 2, but is not limited to two groups. In other embodiments, more than two groups may be used.

[0030] The clamp unit 2 is an arc-shaped clamp, which is connected to the base 1 by fasteners such as pins or bolts to form a three-petal clamp design. Compared with the clamp in the form of two halves, the curvature and size of each piece of the clamp are smaller, which is more conducive to the production and processing using processes such as sheet metal bending and stretching, and is not easily deformed by pressure during transportation.

[0031] The clamp unit 2 and the arc mounting surface 11 of the base together form a complete circular space that can be opened and closed freely. It is opened before the main shaft 3 is installed so that the main shaft can be placed on the bearing seat base from top to bottom without having to penetrate from one side, thereby improving the main shaft installation efficiency and reducing the labor intensity of workers.

[0032] The welding of the clamps in the original plan has been eliminated, which reduces the time taken for finished product production. After the welding-free design, the product can be directly processed and produced using pre-coated anti-corrosion steel, eliminating the subsequent hot-dip galvanizing anti-corrosion process, saving time and cost. The bearing seat can be disassembled and packaged for transportation to reduce the packaging volume; the parts can be assembled after arriving at the project site, which can effectively avoid deformation of the bearing seat due to extrusion during transportation.

[0033] The clamp unit 2 is provided with a connection structure for connecting adjacent clamp units 2 .

[0034] In this embodiment, the connection structure is a bent ear plate 22 , and bolt holes are provided on the bent ear plate 22 . Adjacent bent ear plates 22 are tightened and fixed by bolts.

[0035] like Figure 1 The hoop unit 2 has an outer flange 21, and the flange structure can improve the stress conditions of the bearing seat in the vertical and horizontal directions.

[0036] Furthermore, a curling edge 26 is provided at the connection between the hoop unit 2 and the base.

[0037] The bearing seat also includes a plastic bearing, which is used to be installed in the circular space. In this embodiment, a plastic bearing 4 with a flange is used to prevent axial movement.

[0038] Example 2:

[0039] On the basis of Example 1, Figure 4 In this embodiment, the curling edge 26 is not provided, and an ear plate 24 is provided at the connection between the hoop unit 2 and the base. The ear plate 24 and the outer flange 21 can also achieve the effect of strengthening the strength.

[0040] Example 3:

[0041] Different from Example 1, the clamp unit 2 has an inner flange 25, and the connection structure at the end of the clamp unit 2 is a cross curl 23, which is fixed by installing bolts in the cross curl 23. In this embodiment, the clamp unit 2 can be provided with a curl or an ear plate.

[0042] For use with plastic bearing 5 without flange.

[0043] A photovoltaic tracker comprises the bearing seat of any of the above embodiments, a main shaft 3 and a main shaft rotation drive device, wherein the photovoltaic assembly is mounted on the main shaft 3 and the tracking effect is achieved through the rotation of the main shaft 3.

[0044] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations and modifications may be made to the embodiments of the present invention without departing from the principles described.
