[0037] A 300MW agricultural and photovoltaic complementary power generation project in Guangxi is totally contracted and constructed by our company. The project site is a typical karst landform area, which is mostly steep, ditch, and complex mountainous land with serious land shortage. In order to meet the agricultural and photovoltaic complementary and fully utilize the land resources, it is decided to adopt the combination of fixed support and flexible support, to give play to the advantages of agricultural and photovoltaic complementary, and there are more than 1000 mu of land suitable for flexible support installation on site.

[0038] Example 2

[0039] A kind of cable buckle device for flexible photovoltaic support, as shown in Figure 6 And Figure 7 The technical scheme in the embodiment is basically consistent with that in example 1, and the difference is that (1) the inner pressing plate 3 is provided with anti-skid parts 7 on the side wall away from the outer pressing plate 2 and the inner side of the bottom wall of the U-shaped groove 1; (2) the embodiment is further provided with a limiting bolt 6.

[0040] The anti-skid parts 7 are arranged on the side wall of the inner pressing plate 3 away from the outer pressing plate 2 and the inner side of the bottom wall of the U-shaped groove 1, which can be rubber non-slip pads or anti-skid lines. The anti-skid parts 7 can increase the friction between the inner pressing plate 3, the U-shaped groove 1 and the steel cable. When the steel cable is subjected to external force (such as wind force, vibration, etc.), the sliding of the steel cable in the cable buckle device can be effectively prevented. In mountainous environment, the wind direction and wind force are changeable, and such anti-skid measure can significantly improve the stability of the steel cable fixation. Without the anti-skid parts 7, the contact between the steel cable and the smooth surface of the inner pressing plate 3 and the U-shaped groove 1 is mainly smooth, and the friction is relatively small. Once disturbed by external force, the steel cable is more likely to shift. With the anti-skid parts 7, the friction coefficient of the contact surface is greatly improved, so that the steel cable is more firmly fixed in the cable buckle device.

[0041] The opposite two side walls of the U-shaped groove 1 are respectively provided with through holes penetrating the top wall of the sliding groove 101, and the limiting bolt 6 is arranged in the through hole. The outer pressing plate 2 is inserted into the part of the sliding groove 101, and the limiting hole is arranged on the part of the outer pressing plate 2, and the limiting bolt 6 is connected with the limiting hole through the through hole. The limiting bolt 6 and the limiting hole can increase the connection stability of the outer pressing plate 2 and the U-shaped groove 1. When the cable buckle device provided in the embodiment is used, the inner pressing plate 3 and the U-shaped groove 1 are pressed tightly with the steel cable, and then the limiting bolt 6 is inserted into the limiting hole and tightened, as shown in Figure 7 .

[0042] The cable fastener device for flexible photovoltaic support is high in applicability, simple in installation, convenient for quick installation and applicable to various mountain landform cable structure flexible supports.

[0043] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or part or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
