[0038] As Figures 1-19As shown in the embodiment, the offshore photovoltaic module sliding installation cable system includes a load-bearing cable 1, an end beam 6, and a plurality of middle beams 7 arranged in the middle of the end beam 6. The load-bearing cable 1 is anchored and tensioned on the end beam 6. The middle beam 7 and the end beam 6 are provided with a guide rail type embedding structure capable of enabling the photovoltaic module 4 to continuously slide. The guide rail type embedding structure includes a bottom plate, a guide rail, a Chinese character-shaped buckle, and a bolt. The bottom plate is fixed on the middle beam 7 or the end beam 6. The guide rail is fixed on the bottom plate. The guide rail is in an arc shape. The arc surface is provided with a semicircular guide groove with the same diameter as the load-bearing cable 1. The two side surfaces of the guide rail are provided with clamping grooves. The load-bearing cable 1 is embedded in the guide groove and fixed with the bottom plate through the Chinese character-shaped buckle and the bolt at the clamping groove position. The upper part of the Chinese character-shaped buckle is not exposed at the clamping groove position.

[0039] As shown in Figure 2 , 19 , the photovoltaic module 4 is placed on the two parallel load-bearing cables 1. Under the traction of the traction rope 5, the photovoltaic module 4 can slide from the end beam 6 to the designated installation position. The load-bearing cable 1 is continuously arranged in multiple spans. It is only tensioned and anchored on the end beams 6 at both ends. The guide rail type embedding structure can enable the pulley 81 of the sliding block 8 of the photovoltaic module 4 to smoothly slide through the guide rail of the middle beam 7 and the end beam 6, realize the continuous sliding of the photovoltaic module 4 in multiple spans, and greatly improve the construction efficiency and convenience.

[0040] Specifically, as shown in Figures 3-10 , the middle beam guide rail type embedding structure 2 on the middle beam 7 includes a bottom plate 21, a guide rail 22, a Chinese character-shaped buckle 23, and a bolt 24. The bottom plate 21 is welded and fixed with the middle beam 7. The guide rail 22 is welded and fixed with the bottom plate 21. The guide rail 22 is an arc-shaped steel structure. The arc surface is provided with a semicircular guide groove 221 with the same diameter as the load-bearing cable 1. The middle part is provided with a clamping groove 222 with the same width as the upper part of the Chinese character-shaped buckle 23. The Chinese character-shaped buckle 23 is installed at the clamping groove 222 position of the guide rail 22 and is fixed with the bottom plate 21 through the bolt 24. The Chinese character-shaped buckle 23 embeds the load-bearing cable 1 in the clamping groove 222. The upper part of the Chinese character-shaped buckle 23 is not exposed at the clamping groove 222 position, ensuring that the sliding skid 8 smoothly passes through the guide rail 22.

[0041] As shown in Figures 7-10As shown in , 15-17, the end beam guide rail type embedded structure 3 on the end beam 6 includes a base plate 31, a guide rail 32, an I-shaped clip 33, a bolt 34 and an anchor plate 35. The base plate 31 is welded and fixed to the end beam 6, and the guide rail 32 is welded and fixed to the base plate 31. The guide rail 32 is an arc-shaped steel structure, and its arc-shaped surface is provided with a semicircular guide groove 321. The diameter of the guide groove 321 is consistent with the diameter of the load-bearing cable 1, and a clip groove 322 is provided in the middle thereof.

The anchor plate 35 is installed on the top of the bottom plate 31 and is used for prestressed anchoring of the load-bearing cable 1 .

[0042] like Figures 11-14 As shown, the center beam 7 is provided with a guide mechanism 25 to guide the nylon line. The guide mechanism 25 includes a guide piece 251 and a guide rod 252. The guide piece 251 is bent from flat steel and fixed to the base plate 21 with a connecting bolt 253. Its upper end is tilted outward. The guide rod 252 is processed from smooth round steel. Its lower end is welded to the guide piece 251 and sharpened. The sharpening is for the convenience of welding and for leaving space for guidance. The guide mechanism 25 is installed on the base plate 21 before the line is released. It is used to guide the nylon line during the line release. After the line is released, the guide mechanism 25 is removed and the "X"-shaped buckle 23 is installed. The connecting bolt 253 of the guide mechanism 25 is used to connect the "X"-shaped buckle 23, that is, the bolt 24.

The guide frame 361 is formed by bending flat steel and is fixed to the outside of the bottom plate 31. The inner opening size of the bottom corresponds to the outer frame size of the photovoltaic module 4, and the upper part is inclined outward. The photovoltaic module 4 is hoisted onto the end beam 6 and, under the guidance of the guide frame 361, accurately falls onto the load-bearing cable 1. After being connected to the traction rope 5, it can slide. The photovoltaic module 4 can be easily hoisted onto the end beam 6 and, under the guidance of the guide plate mechanism 36, accurately placed on the load-bearing cable 1. At this time, the end beam 6 has become the starting point for the sliding of the photovoltaic module 4. Under the action of the traction rope 5, the photovoltaic module 4 can slide, which improves the installation efficiency, reduces the process of shifting the installation hull as the installation position of the photovoltaic module 4 changes, simplifies the construction process, and improves the construction accuracy.
