The photovoltaic main beam 7 and the photovoltaic components installed on the photovoltaic main beam 7 are driven to rotate through the relative rotation between the polymer bearing 12 and the bearing seat 14. However, since most of the photovoltaic main beams 7 in the prior art are configured as hollow circular tubes, it is easy to cause slippage and friction between the polymer bearing 12 and the photovoltaic main beam 7, causing damage to the anti-corrosion coating on the surface of the photovoltaic main beam 7. Long-term slippage causes serious corrosion of the photovoltaic main beam 7, and it cannot meet the design service life standard of 25 years.

[0003] To solve the above problems, most existing manufacturers design the cross-section of the photovoltaic main beam 7 to have an angular structure, such as a D-shape, a hexagonal tube, an octagonal tube, etc. However, compared with the photovoltaic main beam 7 with a circular tube structure, the above solution increases the cost a lot compared with the photovoltaic main beam 7 with a hollow circular tube structure.

[0008] As a further improvement of the present invention, the tubular member is configured as a photovoltaic main beam or a connecting tube for connecting the photovoltaic main beam.

[0009] As a further improvement of the present invention, the photovoltaic main beam or the connecting tube is configured as a hollow circular tube, and the fixing surface is configured as an arc-shaped surface matching the outer wall of the hollow circular tube.

[0010] As a further improvement of the present invention, the photovoltaic main beam or connecting tube is set as a hollow rectangular tube, and the fixing surface is set as a plane.

[0011] As a further improvement of the present invention, the photovoltaic main beam or connecting tube is configured as a hollow tubular structure with curved side surfaces and flat upper and lower surfaces, and the fixing surface is configured as a flat surface.

[0012] As a further improvement of the present invention, the connecting block is fixedly connected to the connecting tube, one end of the photovoltaic main beam extends into the interior of the connecting tube, and the photovoltaic main beam and the connecting tube are fixedly connected by a second fastener.

[0013] As a further improvement of the present invention, the first fastener and the second fastener are configured as one of a T-bolt, a rivet, and a screw.

[0014] As a further improvement of the present invention, a countersunk hole is further provided at the connection between the first through hole and the top surface.

[0031] In some optional embodiments, the tubular member is set as a photovoltaic main beam 7, such as Figure 1 The photovoltaic main beam 7 shown in the figure is in the shape of a common hollow circular tube, and a second through hole 8 is respectively opened at the top and bottom of the photovoltaic main beam 7. The fixing surface 4 on the connecting block 1 is set as an arc surface that fits the hollow circular tube. The number, aperture size, and position of the first through holes 6 on the connecting block 1 match the second through holes 8 on the photovoltaic main beam 7. The photovoltaic main beam 7 is fixedly connected to the connecting block 1 by a first fastener 9 that penetrates the first through hole 6 and the second through hole 8 in sequence. The connecting block 1 can be set as follows Fig. 9 The long rectangular block shown in the figure, the connecting block 1 can be set as follows Figure 2 , Figure 3 The triangular prism-like structure shown has two connecting surfaces set as inclined surfaces, which can save costs compared with the connecting block 1 with a long rectangular block structure.

[0032] In some optional embodiments, the tubular member is set as a photovoltaic main beam 7, such as Figure 4 The photovoltaic main beam 7 shown in the figure has a rectangular cross section. Since the top surface of the photovoltaic main beam 7 in the shape of a hollow rectangular tube is set as a plane structure, the fixing surface 4 on the connecting block 1 is set as a corresponding plane structure, such as Figure 8 As shown, after the connecting block 1 is fixedly connected to the photovoltaic main beam 7 by the first fastener 9, a large protruding angular structure is formed on the photovoltaic main beam 7.

When used with a polymer bearing 12 of a corresponding shape, the problem of the connecting tube 10 and the polymer bearing 12 being prone to slipping can be effectively solved.

[0035] In some optional embodiments, similarly, when the tubular member is set as a connecting tube 10, the shape of the connecting tube 10 also has multiple options, such as a hollow circular tube, a hollow rectangular tube, or a hollow tubular structure with curved side surfaces, upper and lower surface planes, etc. The corresponding fixing surface 4 on the connecting block 1 is set to the same shape as the connection of the connecting tube 10 as needed, such as a plane or a curved surface.

[0036] In some optional embodiments, the first fastener 9 and the second fastener 11 can be configured as T-bolts, rivets, screws or other forms of fastening connection functions. As a preferred solution, Fig. 9 As shown, the first fastener 9 can be set as a T-bolt, the T-head of the T-bolt is set as an arc surface, and the first through hole 6 and the second through hole 8 are both set as rectangular holes.
