Description

Technical Field

[0001] The invention relates to a photovoltaic flexible support tensioning cable protection structure, belonging to the technical field of photovoltaic supports. Background Art

[0002] As the global energy depletion problem becomes increasingly serious, solar energy as a renewable green and clean energy is becoming more and more important in my country's energy structure. As an important measure to effectively implement the "dual carbon" policy, photovoltaic power generation projects are developing more and more rapidly. In the construction of photovoltaic power stations, photovoltaic brackets are the core components of photovoltaic power generation systems, and their stability and efficiency directly affect the overall performance of the system.

[0003] Traditional ground-based rigid photovoltaic brackets can no longer fully meet various needs in certain scenarios due to their limitations in pile density, row spacing and clearance. Flexible photovoltaic brackets, with their structural characteristics of "large span, high clearance and long row spacing", effectively solve the adaptability and economic problems of brackets in certain scenarios. The flexible photovoltaic bracket system uses prestressed steel wire ropes stretched between the two fixed points to adapt to situations such as mountain undulations and increased vegetation. It only needs to set up the foundation at the appropriate location and tension the prestressed steel strands or wire ropes.

[0004] However, the load-bearing cable of the flexible photovoltaic support is a variable system with light weight, poor stability and wind resistance. Under the action of wind load, the strings on the flexible photovoltaic support are prone to collision, resulting in damage to the photovoltaic strings. Especially in the case of tight land use, the spacing between flexible photovoltaic supports is getting smaller and smaller, which increases the risk of collision between strings under the action of external wind loads. Therefore, the wind resistance design of flexible photovoltaic supports is particularly important. Summary of the invention

The wind cables are in a tensioned state.

[0008] Furthermore, the wind cable rope group includes more than one group, and each support frame corresponds to one group of wind cable rope groups.

[0009] Furthermore, it also includes a stabilizing cable group, which includes two stabilizing cables, and the two stabilizing cables are respectively arranged at the flexible bracket groups at the outermost edges of the left and right sides of the tensioning cable protection structure, one end of the stabilizing cable is connected to the support frame of the flexible bracket group on the corresponding side, and the other end of the stabilizing cable is fixedly connected to the ground on the corresponding side through a stabilizing side pile, and the end of the stabilizing cable connected to the stabilizing side pile is farther from the center of the tensioning cable protection structure than the end connected to the support frame.

[0010] Further, the horizontal cables and the oblique cables are connected by an integrated node, the integrated node is arranged on the support frames at the two sides of each group of flexible brackets, and the integrated node includes a body; The main body includes an inclined surface and a vertical surface, and a horizontal through hole and an oblique through hole are provided on the main body.

[0011] Furthermore, the outlet of the oblique through hole located on the vertical surface of the body is located above the outlet of the horizontal through hole located on the vertical surface of the body.

[0012] Furthermore, the main body includes four ribs, a first rectangular plate, a second rectangular plate and a third rectangular plate. The edge of the first rectangular plate is fixedly connected to the second rectangular plate to form an L-shaped structure. The third rectangular plate is fixedly connected to the L-shaped structure through the four ribs. The four ribs are distributed at equal intervals. The side of the third rectangular plate away from the ribs serves as the inclined surface of the main body, and the side of the second rectangular plate away from the ribs serves as the vertical surface of the main body.

[0013] Furthermore, the support frame includes a central column and a crossbeam, the middle portion of the crossbeam is fixedly connected to the upper end of the central column, and the lower end of the central column is fixedly connected to the ground.

[0014] Furthermore, concrete is poured into the inner cavity at the lower part of the central column.

[0015] Preferably, the support rod is a rod-type damper.

[0016] The beneficial effects of the present invention are: compared with the prior art, 1) The present invention is connected between the support frames of two adjacent flexible bracket groups through support rods. When the wind blows the photovoltaic modules and causes the photovoltaic brackets to move, the support rods play a role in fixing the two adjacent photovoltaic brackets, avoiding collision or mutual friction between adjacent photovoltaic modules, and reducing the damage rate of photovoltaic modules; 2) The present invention uses wind cables to fix the left and right sides of the support frame, and applies a tension force to the left and right sides of the photovoltaic bracket to prevent the photovoltaic bracket from moving in the opposite direction of the wind cable tension due to wind force, causing deformation and damage to the photovoltaic bracket; 3) The present invention uses a stabilizing cable to hold the left and right sides of the support frame of the flexible bracket group, providing tension constraints on the left and right sides of the photovoltaic module, thereby improving the anti-sway performance of the flexible bracket when subjected to external wind force; 4) The present invention connects the horizontal cable and the oblique cable through an integrated node, and utilizes the characteristic that the central axis of the oblique through hole and the horizontal through hole are located in the same plane, so that the tension of the horizontal cable and the oblique cable is always located in the same plane, thereby avoiding the moment generated at the connection node of the horizontal cable and the oblique cable to cause damage to the support frame, thereby improving the overall structural stability of the photovoltaic flexible support; 5) The present invention directly fixes the center column to the ground, and the center column is fixed to the ground statically, which can reduce the shaking of the flexible bracket as a whole. On the other hand, concrete is poured into the center column, so that the anti-sway performance of the flexible photovoltaic bracket is improved while the anti-bending performance of the center column is improved, thereby preventing the center column from breaking in strong winds; 6) The present invention is connected between the support frames of two adjacent flexible bracket groups through a rod-type damper. When wind blows the photovoltaic components and causes the photovoltaic brackets to move, the rod-type damper fixes the two adjacent photovoltaic brackets to avoid collision or mutual friction between adjacent photovoltaic components, thereby reducing the damage rate of the photovoltaic components. At the same time, when the rod-type damper is squeezed or stretched by the support frame, the rod-type damper will dissipate energy, thereby reducing the overall shaking of the photovoltaic bracket.
