Description

Technical Field

[0001] The utility model relates to the technical field of new energy photovoltaic power generation, in particular to a flexible photovoltaic bracket. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] "Fish-photovoltaic complementarity" refers to the combination of fishery farming and photovoltaic power generation. A photovoltaic panel array is set up above the water surface of the fish pond, and fish and shrimp can be farmed in the water area below the photovoltaic panels. The photovoltaic array can also provide good shielding for fish farming, forming a new power generation model of "generating electricity above and farming fish below".

[0004] In the "Fish-Photovoltaic Complementary" project, the photovoltaic panel array is supported by a flexible photovoltaic bracket. At the end of the flexible photovoltaic bracket, two inclined cables are generally connected with pull-out piles as the horizontal load-bearing components of each array group.

[0005] This method requires a large amount of construction work and requires a large number of pull-out piles at the ends. At the same time, the cable-stayed cable has a strong tensile bearing capacity. When two cables are used, the tensile bearing capacity of the material is usually much lower than its designed bearing capacity, resulting in low material utilization and waste of materials. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide a flexible photovoltaic bracket, which can significantly reduce the number of pull-out piles while ensuring the stability of the structural system, thereby saving materials while shortening the construction period.

In order to ensure the horizontal bearing capacity of the pull-out pile, its cross-section is reduced, and a rigid tie rod is added between the pull-out pile and the column pile, so that the pull-out pile and the column pile can jointly bear the horizontal force of the inclined cable, thereby making full use of the bearing capacity of the existing components.

[0021] Furthermore, a lug plate is provided on the top of the pull-out pile, and an anchor is provided on the lug plate;

[0022] The ear plate is connected to one end of the inclined cable through an anchor.

[0023] By adopting the above technical solution, the connection between the inclined cable and the pull-out pile is facilitated by the arrangement of the ear plate, and the stability of the connection between the pull-out pile and the inclined cable is enhanced by the anchor.

[0024] Furthermore, the steel cross beam is symmetrically provided with stiffening ribs on both sides along the length direction, the stiffening ribs on one side are connected to the triangular brace, and the stiffening ribs on the other side are connected to the load-bearing cables.

[0025] By adopting the above technical solution, the tie points of the load-bearing cables and the triangular braces are located on the same cross section of the steel beam, making the force more balanced.

[0026] Preferably, the stiffening rib is connected to the load-bearing cable via an anchor.

[0027] By adopting the above technical solution, the stability of the connection between the steel beam and the load-bearing cable is enhanced.

[0030] By adopting the above technical solution, the stability of the connection between the inclined cable and the triangular support is enhanced.

[0031] Furthermore, the steel cross beam is welded to the column pile.

[0032] By adopting the above technical solution, the steel beams and column piles are connected by welds, making the structure more stable.

[0033] The technical solution provided in the utility model has at least the following technical effects or advantages:

[0034] 1. The technical solution provided by the utility model adopts a "stayed cable + triangular brace" as the main tension member of the end horizontal load-bearing structure. Compared with the traditional form of two stay cables, it can not only ensure the stability of the structural system, but also greatly reduce the number of pull-out piles, thus saving materials while shortening the construction period and having good economic benefits.

[0035] 2. In order to ensure the horizontal bearing capacity of the pull-out piles and reduce their cross-section, a rigid tie rod is added between the pull-out piles and the column piles so that the pull-out piles and the column piles can jointly bear the horizontal force of the inclined cable.
