Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic module installation, and particularly relates to an inclined pull embedded part and a flexible photovoltaic bracket. Background Technique

[0002] A flexible photovoltaic module bracket is a new type of photovoltaic support structure. It is usually made of flexible materials, can adapt to changing terrains, reduce land occupation, and improve the overall stability and power generation efficiency of the photovoltaic system. The design of the flexible bracket allows the module to move within a certain range to adapt to the influence of wind force and other environmental factors, reducing damage caused by wind vibration.

[0003] Since the flexible bracket uses prestressed steel cables for tensioning, an inclined pull structure is required at the end to be connected to the inclined pull foundation to transfer the prestress to the inclined pull foundation to achieve balance. For example, the Chinese utility model patent with the publication number CN214626855U discloses a steel cable pulling structure for a photovoltaic bracket. In this scheme, an inclined pull support needs to be installed on the inclined pull foundation to connect the inclined pull cable. The inclined pull support is connected to the inclined pull foundation using multiple nuts and embedded parts. Multiple embedded parts and supports are required, which uses a lot of materials. The installation requires installing the support first, with many installation steps and high labor costs.

[0004] In view of this, it is necessary to propose an inclined pull embedded part and a flexible photovoltaic bracket to solve the problems of large steel consumption of the support and troublesome installation in the existing flexible photovoltaic bracket. Content of the Utility Model

As shown in the figure, the stay - cable embedded part of this embodiment includes a concrete stay - cable foundation 1 and an embedded part poured in the concrete stay - cable foundation 1; the concrete stay - cable foundation 1 is a cylindrical cement - concrete pier column, most of the embedded part is embedded in the concrete stay - cable foundation 1, and a small part is exposed on the upper surface of the concrete stay - cable foundation 1; the embedded part includes a U - shaped steel bar 2 and a first rib plate 3 fixedly connected to the inner side of the U - shaped end of the U - shaped steel bar 2. The first rib plate 3 fills the inner side of the U - shaped end of the U - shaped steel bar 2, that is, the edge of the first rib plate 3 is in good contact with the inner side of the U - shaped steel bar 2. Specifically, a U - shaped solid metal plate adapted to the inner side size of the U - shaped end can be selected as the first rib plate 3 and welded to the inner side of the U - shaped steel bar 2. Among them, a stay - cable connection hole 5 is opened in the middle of the first rib plate 3, and this hole is used to connect the stay - cable 18 or rod.

[0037] To improve the structural stability, as Figure 1 shown, a second rib plate 6 is provided in the direction perpendicular to the stay - cable direction F. The second rib plate 6 is specifically perpendicular to the first rib plate 3 and the U - shaped steel bar 2. A notch is opened on the second rib plate 6, and the notch of the second rib plate 6 is inserted into the first rib plate 3, so that the second rib plate 6 vertically enters the inner side of the U - shaped end of the U - shaped steel bar 2, and then the second rib plate 6 is welded to the first rib plate 3, making the second rib plate 6, the first rib plate 3, and the U - shaped steel bar 2 an integral embedded part. The first rib plate 3 and the second rib plate 6 enhance the vertical and horizontal stress - bearing performance and prevent the embedded part from deforming when being tensioned.
