Description

Technical Field

[0001] This utility model relates to a central column structure, and more particularly to a lightweight flexible support central column structure. Background Technology

[0002] Flexible photovoltaic (PV) mounting systems are typically installed in mountainous areas with irregular terrain, which presents numerous design challenges. Unlike fixed PV mounting systems on flat ground, the slope, undulations, and rocks of mountainous terrain increase the complexity of system design. To ensure stable operation of PV modules and avoid structural failures and damage caused by uneven terrain, flexible PV mounting systems for mountainous areas need to possess strong adaptability and durability.

[0003] Among them, the central column of the mountain flexible support needs to provide support for the main cable of the photovoltaic module string, fix the photovoltaic module at a specified height, and also resist the negative impact of wind pressure and snow pressure on the photovoltaic module on the system stability. Therefore, the central column of the flexible support is relatively important in the flexible support system.

[0004] Meanwhile, the number of spans in a single row of flexible supports is often large, so the number of central columns used in flexible supports is much greater than that of side columns. The amount of steel used and the weight of the central columns often have a significant impact on the production and transportation costs of the flexible support system. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight flexible support column structure.

[0006] The purpose of this utility model is achieved through the following technical solution: a lightweight flexible support column structure, including a central column inclined beam, a corner brace base plate, a central column corner brace, a central column upright, and a central column base plate;

[0007] The corner brace base plate is fixedly connected to both sides of the lower end of the central column inclined beam. One end of the central column corner brace is fixedly connected to the lower end of the corner brace base plate, and the other end is fixedly connected to the central column upright. The lower end of the central column upright is fixedly connected to the central column base plate, and an mounting plate is fixed to the lower end of the central column base plate.

[0008] The connection between the central column corner brace and the central column upright is fixed with a first transverse ear plate and a second transverse ear plate, and the upper end of the central column upright is fixed with a longitudinal ear plate.

[0009] Furthermore, the fixed connection method is welding.

[0010] Furthermore, the tilt angle of the central column inclined beam is determined by the optimal power generation tilt angle of the photovoltaic module.

[0011] Furthermore, the length of the central column is determined by the arrangement of the central piles and the height of the pile foundation.

[0012] Furthermore, the central column structure of the support can be fixedly connected to the connecting rod through the first transverse ear plate and the second transverse ear plate; the central column structure of the support can be fixedly connected to the longitudinal support rod through the longitudinal ear plate, and the longitudinal support rod is fixedly connected to the horizontal ground through the longitudinal support pile.

[0013] The beneficial effects of this invention are as follows: After the flexible support column structure of this invention is used in a flexible support system, it can reduce the amount of steel used in the flexible support column, thereby lowering the production cost of the flexible support system, while maintaining the wind and snow pressure resistance of the flexible support column. Furthermore, the reduced weight of the flexible support column can further reduce the transportation cost of the flexible support system. Attached Figure Description

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments, and the purpose and effects of the present invention will become more apparent.

[0021] like Figures 1-4 As shown, this utility model provides a lightweight flexible support column structure, including a central column inclined beam 1, a corner support base plate 2, a central column corner support 3, a central column upright 7, a central column base plate 8, and a mounting plate 9.

[0022] The corner support base plates 2 are welded to both sides of the lower end of the central column inclined beam 1. One end of the central column corner support 3 is welded to the lower end of the corner support base plate 2, and the other end is welded to the central column upright 7. The lower end of the central column upright 7 is welded to the central column base plate 8, and the lower end of the central column base plate 8 is welded to the mounting plate 9. The mounting plate 9 is connected to the central pile by bolts to complete the installation of the central column. The inclination angle of the central column inclined beam 1 is determined by the optimal power generation tilt angle of the photovoltaic module, and the length of the central column upright 7 is determined by the arrangement of the central piles and the pile foundation height.

[0023] The connection between the central column corner brace 3 and the central column upright 7 is welded with a first transverse ear plate 4 and a second transverse ear plate 5, forming a reinforcing rib. Besides its transverse connection function, this also improves its resistance to deformation. A longitudinal ear plate 6 is fixedly connected to the upper end of the central column upright 7. Figure 5 As shown, the central column structure of the bracket can be fixedly connected to the connecting rod through the first transverse ear plate 4 and the second transverse ear plate 5 to form a transverse connection between the central columns; the central column structure of the bracket can be fixedly connected to the longitudinal support rod through the longitudinal ear plate 6, and the other end of the longitudinal support rod is fixed to the longitudinal support pile to form longitudinal support for the central column; wherein, the ear plate is connected to the connecting rod and the longitudinal support rod by bolt connection.

[0024] The lateral connections between the central columns enhance the overall wind resistance of the flexible support system, while the longitudinal bracing structure of the central columns strengthens their stability and resistance to deformation. The lengths of both the lateral connecting rods and the longitudinal bracing rods are adjustable to meet specific usage requirements.
