[0039] Reference Figures 1-8The bottom of the support column 3 is connected to the ground by a special high-strength anchor bolt with a specification of M24, which is embedded 1 meter underground and fixed by concrete pouring, and the surface is brushed with two coats of anti-rust primer and two coats of gray finish paint to prevent rust. The cable-stayed assembly 5 uses a steel wire rope with a diameter of 16 mm and is made of 7 strands of steel wire with a diameter of 2 mm, and its cable-stayed installation clamp 17 is firmly connected to the ground with M16 expansion bolts (4 for each clamp). The bottom of the placing turntable 12 is equipped with a 6205 bearing to ensure flexible rotation to facilitate the operation of the cable lock parking structure 11, and the edge is equipped with a 5mm rubber protection ring to prevent collision. The nylon pulley of the pulley device 1 has a diameter of 200mm and a wheel groove depth of 15mm, and the rolling shaft column 15 at both ends is equipped with a 6304 bearing to reduce friction and improve efficiency. The arc surface of the compression structure 8 is covered with a 3mm rubber pad to buffer and increase friction, and is welded to the second I-beam frame 19 through an 8mm steel plate connecting seat.

[0040] During assembly, the support column 3 is first firmly installed on the ground through the bolts at the bottom to provide a stable support foundation for the entire support structure.

[0045] The anti-slip tensioning device 2 between the first I-beam frame 9 and the second I-beam frame 19 is used to prevent the second tensioning rope 21 from slipping. The anti-slip key 16 in it cooperates with the tensioning device 7, when the second tensioning rope 21 has a tendency to slip under external force, the anti-slip key 16 relies on the friction between the serrated pattern and the internal clamping groove of the tensioning device 7 to prevent slipping, ensuring the stability and safety of the entire structure.

[0046] In summary:

[0047] 1. In the device, the support column 3 at the bottom is connected to the ground by a special high-strength foundation bolt with a specification of M24, which is 1 meter deep underground and is fixed by concrete pouring, and the surface is brushed with two coats of anti-rust primer and two coats of gray finish paint to prevent rust. The stay assembly 5 uses a steel wire rope with a diameter of 16 mm and is made of 7 strands of steel wire with a diameter of 2 mm, and its stay installation clamp 17 is firmly connected to the ground with M16 expansion bolts (4 for each clamp). The bottom of the turntable 12 is installed with a 6205 bearing to ensure flexible rotation to facilitate the operation of the cable lock parking structure 11, and a 5mm rubber protection ring is provided on the edge to prevent collision. The nylon pulley of the pulley device 1 has a diameter of 200mm and a groove depth of 15mm, and the two ends of the rolling shaft column 15 are equipped with 6304 bearings to reduce friction and improve efficiency.

[0048] 2. During assembly, first, the support column 3 is firmly installed on the ground through the bolts at the bottom to provide a stable support foundation for the entire support structure.

[0049] The stay assembly 5 is installed obliquely from the front and back of the first I-beam frame 9 and the third I-beam frame 20 to the bottom, and its bottom end is fixed to the ground through the stay installation clamp 17. The stay assembly 5 uses its oblique tension to tighten the I-beam frames to the sides, enhancing the lateral stability of the entire support structure and preventing lateral overturning when bearing the weight of photovoltaic panels and external forces such as wind load.

[0050] The placing turntable 12 is placed on one side of the device, and the cable locking parking structure 11 on the top of the placing turntable 12 can be used for parking and arranging related cable and other components, facilitating construction and maintenance operation.
