Description

Technical Field

[0001] The utility model relates to an intermediate column and a photovoltaic flexible bracket, belonging to the technical field of photovoltaic equipment. Background Art

[0002] The photovoltaic flexible support system requires safe and stable working performance requirements. If there is a problem in any component or node in the support system, it will have a great impact on the power generation of the entire photovoltaic base and increase the maintenance cost of the entire project.

[0003] like Figure 7 、 Figure 8 As shown, when the existing photovoltaic flexible bracket steel strand passes through the U-shaped mounting part 3, since the U-shaped mounting part 3 is welded to the end of the first cross bar 2, the steel strand is fixed by two first U-shaped bolts 4. After the photovoltaic component 22 is installed on the top of the steel strand, the steel strand is tensioned by the tensioning equipment to provide prestress. Since the U-shaped mounting part 3 cannot rotate, it is easy to cause the steel strand to be subjected to unbalanced force at the U-shaped mounting part 3, and it is easy to cause only one first U-shaped bolt 4 to bear a larger load, affecting the load capacity of the entire steel strand, and even causing the first cross bar 2 to twist and deform. At the same time, long-term use can easily cause wear or even breakage of the steel strand.

[0004] In order to solve the above problems, this application proposes an intermediate column and a photovoltaic flexible bracket. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an intermediate column and a photovoltaic flexible bracket. The load-bearing cable can better adapt to rugged terrain conditions and follow the slope, thereby avoiding the situation in which the load-bearing cable in the prior art is subjected to unbalanced force relative to the U-shaped mounting part after tensioning is completed, reducing the wear of the load-bearing cable, and effectively solving the problems in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A middle column and a photovoltaic flexible bracket include a vertical support rod, a first cross rod, a U-shaped mounting piece, and a first U-shaped bolt. The first cross rod is fixedly connected to the top of the vertical support rod. The first U-shaped bolt is fixedly connected to the U-shaped mounting piece for installing a steel strand. Before the steel strand is tensioned, the U-shaped mounting piece can be rotatably arranged at the left and right ends of the first cross rod. After the steel strand is tensioned, the U-shaped mounting piece is fixedly arranged at the left and right ends of the first cross rod.

[0008] As a further improvement of the present invention, both left and right ends of the first crossbar are rotatably connected to rotating ends, the rotating ends are configured as an annular structure, and the U-shaped mounting piece is fixedly connected to the rotating ends.

[0010] As a further improvement of the present invention, a first circular mounting hole is provided on the connecting ring, and a first arc-shaped mounting hole is provided on both the left and right ends of the first cross bar. The rotating end is fixedly connected to the first cross bar by a screw. During installation, the screw is passed through the first arc-shaped mounting hole and the first circular mounting hole, and a nut is screwed on the other end of the screw. When the steel wire rope is tensioned, the nut is tightened to fix the U-shaped connector on the rotating end.

[0011] As a further improvement of the present invention, the rotating end and one end of the first cross bar close to each other are fixedly connected with a flange, and the rotating end is fixedly connected to the first cross bar through the flange.

[0012] As a further improvement of the present invention, a second circular mounting hole and a second arc-shaped mounting hole are symmetrically provided on the flange, and two flanges are arranged in pairs as a group. The second circular mounting holes and the second arc-shaped mounting holes on the paired flanges are staggered, that is, the second circular mounting hole on one flange is used in conjunction with the second arc-shaped mounting hole on the other flange.

[0013] As a further improvement of the present invention, a clamping piece is fixedly connected below the U-shaped mounting piece through a second U-shaped bolt.

[0014] As a further improvement of the present invention, the clamping piece is set to be U-shaped, and a connecting plate is fixedly connected to the top of the clamping piece. The length of the second U-shaped bolt is greater than the length of the first U-shaped bolt. By increasing the length of the second U-shaped bolt, the second U-shaped bolt is used to fix the clamping piece and the U-shaped connecting piece at both ends of the first cross bar while fixing the steel wire rope.

[0015] A photovoltaic flexible bracket includes the above-mentioned middle column, and the vertical support rods are fixedly connected to ear plates. Adjacent vertical support rods are reinforced and connected by second cross rods and oblique connecting rods, and load-bearing cables are provided at the tops of the vertical support rods.

[0017] The beneficial effects of the utility model include: an intermediate column and a photovoltaic flexible bracket, which can rotate the U-shaped mounting piece relative to the first cross bar. During the tensioning process, the movement of the load-bearing rope made of steel strands can drive the U-shaped mounting piece to adaptively rotate relative to the first cross bar, so that after the steel strands are fixed on the U-shaped mounting piece, the steel strands and the U-shaped mounting piece are in a parallel state, and the two first U-shaped bolts can both make good contact with the steel strands, so that the load-bearing ropes can better adapt to rugged terrain conditions and follow the slope, avoiding the situation in which the load-bearing ropes in the prior art are subjected to unbalanced force relative to the U-shaped mounting piece after tensioning is completed, thereby reducing the wear of the load-bearing ropes.

The screw 8 passes through the first arc-shaped mounting hole 10 and the first circular mounting hole 11, and a nut is screwed on the other end of the screw 8. During the tensioning process, the steel strand drives the rotating end 7 to rotate slightly relative to the first cross bar 2 to avoid unbalanced force on the steel strand at the U-shaped connector 3. When the steel strand is tensioned, tighten the nut and the first U-shaped bolt 4 to fix the U-shaped connector 3 on the rotating end 7 and the steel strand is fixed on the top of the U-shaped mounting member 3.

[0040] Furthermore, a second circular mounting hole 16 and a second arc-shaped mounting hole 17 are symmetrically provided on the flange 15. Two flanges 15 are arranged in pairs as a group, and the second circular mounting holes 16 and the second arc-shaped mounting holes 17 on the paired flanges 15 are staggered, that is, the second circular mounting hole 16 on one flange 15 is used in conjunction with the second arc-shaped mounting hole 17 on the other flange 15, and the two flanges 15 are fixed by bolts.

[0041] During installation, the flanges 15 are docked together so that the second circular mounting hole 16 is aligned with the center of the second arc-shaped mounting hole 17. The steel strand is placed on the top of the U-shaped mounting member 3 through the first U-shaped bolt 4. The bolt is passed through the first arc-shaped mounting hole 10 and the first circular mounting hole 11. The nut is screwed on the other end of the bolt for pre-tightening.

Before the steel strand is tensioned, the U-shaped mounting member 3 can be rotatably set at the left and right ends of the first cross bar 2. After the steel strand is tensioned, the U-shaped mounting member 3 and the clamping member 12 are fixed to the left and right ends of the first cross bar 2 by the second U-shaped bolt 14.

[0044] Specifically, the clamping member 12 is configured to be U-shaped, a connecting plate 13 is fixedly connected to the top of the clamping member 12 , and the length of the second U-shaped bolt 14 is greater than that of the first U-shaped bolt 4 .

[0045] During installation, the U-shaped connector 3 and the clamping member 12 are connected to the first cross bar 2, the steel strand is placed on the top of the U-shaped mounting member 3 through the first U-shaped bolt 4, and pre-tightened at the bottom with a nut. During the tensioning process, the annular structure composed of the U-shaped connector 3 and the clamping member 12 can be rotated slightly relative to the first cross bar 2 to avoid unbalanced force on the steel strand at the U-shaped connector 3. When the steel strand is tensioned, the nut is tightened to fix the U-shaped connector 3 and the clamping member 12 on the first cross bar 2, and at the same time, the steel strand is fixed to the top of the U-shaped connector 3.

The top of the vertical support rod 1 is provided with a load-bearing cable 25, which is specifically set as a steel wire rope.

[0048] In some optional embodiments, a photovoltaic assembly 22 is fixedly installed on the top of the load-bearing cable 25, and terminal columns 21 are provided at both ends of the load-bearing cable 25. The ends of the load-bearing cable 25 are anchored on the terminal columns 21, and the terminal columns 21 are fixedly connected to the ground piles 24 through the inclined cables 23.

[0049] By rotating the U-shaped mounting member 3 relative to the first cross bar 2, the movement of the load-bearing rope 25 made of steel strands can drive the U-shaped mounting member 3 to adaptively rotate relative to the first cross bar 2 during the tensioning process, so that after the steel strands are fixed on the U-shaped mounting member 3, the steel strands and the U-shaped mounting member 3 are in a parallel state, which can enable the load-bearing rope 25 to better adapt to rugged terrain conditions and follow the slope, avoiding the situation in the prior art where the load-bearing rope 25 is subjected to unbalanced force relative to the U-shaped mounting member 3 after tensioning is completed, thereby reducing the wear of the load-bearing rope 25.
