DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1, as Figure 1-4 As shown, the utility model provides a technical solution for the connection structure of anchors and steel strands: it includes two concrete bases 1, two vertical poles 3 are provided on one side of the two concrete bases 1, cement base columns 2 are fixed to the bottom of the two concrete bases 1 and the bottom of the two vertical poles 3, and docking components are fixed to the tops of the two vertical poles 3. The docking components include a docking frame 8, a docking sleeve 10 is provided inside the docking frame 8, and a bell mouth 11 is provided on one side of the docking sleeve 10.

[0023] The effect achieved by the entire embodiment 1 is that by adding the bell mouth 11 to the docking sleeve 10, the friction between the cable and the edge of the docking sleeve 10 can be reduced to the maximum extent, thereby reducing friction under the actual working state of the cable and ensuring the safety of the component.

[0024] Example 2, as Figure 1-4 As shown, an anchor 9 is provided on the top of the docking frame 8, a fastener 12 is provided on one side of the docking frame 8, one end of the docking sleeve 10 extends to one side of the fastener 12, a crossbeam 5 is provided between the opposite sides of the two vertical poles 3 near the top edge, and a fixing seat 6 is installed on the top of the two concrete bases 1. The tops of the two fixing seats 6 are provided with locking buckles 7, and the inner sides of the two locking buckles 7 are provided with oblique threaded steel bars 4. One ends of the two oblique threaded steel bars 4 extend to the inside of the docking sleeve 10, and the bottom outer surfaces of the two oblique threaded steel bars 4 are in contact with the inner wall of the bell mouth 11.

[0025] The effect achieved by the entire embodiment 2 is that, during the factory processing of the butt joint sleeve 10, a butt joint sleeve 10 with a bell mouth 11 is used. After the on-site tensioning is completed, the steel strand will swing up and down due to the action of gravity and wind suction. Due to the design of the bell mouth 11, the arc surface between the steel strand and the inner wall of the bell mouth 11 fits together, which can reduce the friction between the steel strand and the butt joint sleeve 10.

[0026] Instructions for use: During the construction of photovoltaic brackets, especially in mountain photovoltaic systems using multi-span prestressed cable structures, the cable surface is often easily worn due to the accumulated friction generated by the cable sagging and the anchor 9, resulting in anti-corrosion failure, which in turn affects the safety of the photovoltaic components in the later stage. This device can minimize the friction between the cable and the edge of the docking sleeve 10 by adding a bell mouth 11 to the docking sleeve 10, reduce friction under the actual working state of the cable, and ensure the safety of the component. During the processing of the docking sleeve 10 in the factory, a docking sleeve 10 with a bell mouth 11 is used. After the on-site tensioning is completed, the steel strand will swing up and down due to the action of gravity and wind suction. Due to the design of the bell mouth 11, the arc surface between the steel strand and the inner wall of the bell mouth 11 fits together, which can reduce the friction between the steel strand and the docking sleeve 10.

[0027] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
