Description

Technical Field

[0001] The utility model relates to a middle column of a flexible bracket adaptable to terrain, belonging to the technical field of photovoltaic bracket equipment. Background Art

[0002] Flexible photovoltaic supports are usually composed of flexible load-bearing cables, steel columns, steel inclined columns and inclined cables, steel beams and foundations. They have advantages that traditional supports lack, such as simple structure, less material used, light weight, and short construction period. Existing flexible photovoltaic supports have certain problems in actual use. Since their photovoltaic modules are connected in series by cables made of steel strands, the load-bearing cables will inevitably deform due to terrain reasons when passing through the middle columns. Most of the existing middle columns only use U-bolts to press down and fix the load-bearing cables. The load-bearing cables are severely worn here and even break, causing damage to the photovoltaic modules. In addition, when the middle column is an upper pull-up column, after the steel strands are tensioned, the U-bolts cannot form an effective connection with the steel strands. Under the action of long-term dynamic loads, the nuts of the U-bolts will loosen or even fall off. In order to solve the above problems, this application proposes a middle column of a flexible support that mainly adapts to the terrain. Utility Model Content

The cable fixing mechanism includes an upper fixing plate and a lower fixing plate. When the load-bearing cable bends upward after tensioning, the load-bearing cable is fixedly connected to the bottom of the upper fixing plate by a U-shaped bolt. When the load-bearing cable bends downward after tensioning, the load-bearing cable is fixedly connected to the top of the lower fixing plate by a U-shaped bolt.

[0006] As a further improvement of the present invention, the ends of the upper fixing plate and the lower fixing plate are bent to form guide plates for guiding the load-bearing cables.

[0007] As a further improvement of the present invention, the guide plate on the upper fixing plate is bent upward, and the guide plate on the lower fixing plate is bent downward.

[0026] Example 1

[0027] like Figures 1-4 As shown, a middle column of a flexible support that adapts to the terrain is mainly composed of a vertical support rod 1, a transverse support rod 2, a cable fixing mechanism 4, and a load-bearing cable 5, wherein the transverse support rod 2 is fixedly connected to the top of the vertical support rod 1, the cable fixing mechanism 4 is fixedly connected to the two ends of the transverse support rod 2, and the load-bearing cable 5 is fixedly connected to the cable fixing mechanism 4. The cable fixing mechanism 4 is specifically composed of an upper fixed plate 7, a lower fixed plate 6, and a connecting plate connecting the upper fixed plate 7 and the lower fixed plate 6. When the load-bearing cable 5 bends upward after tensioning, the load-bearing cable 5 is fixedly connected to the bottom of the upper fixed plate 7 by a U-bolt 8. When the load-bearing cable 5 bends downward after tensioning, the load-bearing cable 5 is fixedly connected to the top of the lower fixed plate 6 by a U-bolt 8.

[0028] like Figure 2 As shown, when the load-bearing cable 5 bends upward, that is, the load-bearing cable 5 bears the upward pulling force,

[0029] Furthermore, in order to improve the stability of the connection between the transverse support rod 1 and the transverse support rod 2, a diagonal support rod 3 is fixedly connected between the vertical support rod 1 and the transverse support rod 2 for reinforcement.

[0030] In some optional embodiments, the ends of the upper fixing plate 7 and the lower fixing plate 6 are bent to form guide plates 9 for guiding the load-bearing cables 5 .

[0031] Furthermore, the guide plate 9 on the upper fixing plate 7 is bent upward, and the guide plate 9 on the lower fixing plate 6 is bent downward.

[0032] In some optional embodiments, the number of upper fixing plates 7 is set to one, and a first connecting plate 10 is fixedly connected between the upper fixing plate 7 and the lower fixing plate 6 .

[0033] Furthermore, the first connecting plate 10 is configured as an isosceles trapezoid.

[0034] like Figure 2 or Figure 4As shown, the lower fixing plate 6 and the first connecting plate 10 are both set as two pieces. The lower fixing plate 6 is fixedly connected to the side of the transverse support rod 2 by welding. The first connecting plate 10 is respectively fixedly connected to the lower fixing plate 6 and the upper fixing plate 7 by welding, thereby forming a through-hole space for the load-bearing cable 5 to pass through. If the load-bearing cable 5 bends upward after being tensioned, that is, the load-bearing cable 5 is subjected to upward pulling force, the U-bolt 6 opens upward to fix the load-bearing cable 5 on the upper fixing plate 7. If the load-bearing cable 5 bends downward after being tensioned, that is, the load-bearing cable 5 is subjected to downward pressure, the U-bolt 6 opens downward to fix the load-bearing cable 5 on the lower pressure plate 6. The guide plate 9 provided can increase the force-bearing area of ​​the load-bearing cable 5 at the cable fixing mechanism 4. When the load-bearing cable 5 vibrates up and down due to wind load, the upper fixing plate 7, the lower fixing plate 6 and the guide plate 9 can play an effective blocking role to prevent the load-bearing cable 5 from escaping from the cable fixing mechanism 4 and causing danger.

[0035] Example 2

[0036] like Figure 5-Figure 8 As shown, the number of upper fixing plates 7 is set to two, the number of guide plates 9 provided on each upper fixing plate 7 is set to one, and a second connecting plate 11 is fixedly connected between the upper fixing plate 7 and the lower fixing plate 6 .

[0037] In some optional embodiments, the second connecting plate 11 is configured as a rectangular plate.

[0038] Compared with embodiment 1, the use of two upper fixing plates 7 can provide one more support point when the load-bearing cable 5 is subjected to the upward pulling force, thereby reducing the concentrated load on the load-bearing cable 5 and being suitable for occasions with longer single-row spans.

[0039] The above is a preferred embodiment of the present invention. The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
