Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic bracket accessories, and in particular relates to a horizontal tie rod suitable for photovoltaic brackets. Background Technology

[0002] In photovoltaic power generation systems, photovoltaic brackets are an important structure supporting photovoltaic modules, and their stability is directly related to the operational safety and efficiency of the entire power generation system. Horizontal tie rods, as key components of photovoltaic brackets, play a role in connecting and reinforcing the steel beams of photovoltaic brackets, thereby maintaining the overall structural stability of photovoltaic brackets.

[0003] However, the existing horizontal tie rods of photovoltaic (PV) brackets have the following drawbacks in actual use: First, the existing horizontal tie rods of PV brackets require the installation of independent shims on site (increasing the time and difficulty of on-site work), and there is a lack of fixed connection between the shims and the PV bracket steel beams (during long-term use, the shims are prone to loosening, which in turn affects the overall stability of the PV bracket); Second, the length of the existing horizontal tie rods of PV brackets is fixed, making it difficult to adapt to PV bracket steel beams with different spacing (the spacing of the PV bracket steel beams needs to be varied according to the actual installation requirements and location).

[0004] Therefore, it is essential to invent a horizontal tie rod suitable for photovoltaic brackets. Utility Model Content

[0005] To address the above problems, this utility model proposes a horizontal tie rod suitable for photovoltaic brackets. The technical solution used is as follows:

[0006] A horizontal tie rod suitable for photovoltaic (PV) brackets includes a tie rod body, washers, nuts, and mounting holes. Each end of the tie rod body has a corresponding mounting hole passing through it, which is formed on the corresponding PV bracket steel beam. Washers are provided on both sides of each mounting hole, and these washers are fixed to the PV bracket steel beam by welding. Nuts are threadedly fixed to both ends of the tie rod body, and these nuts are respectively fitted into the corresponding washers.

[0007] Furthermore, the tie rod body includes a first connecting post, a sleeve, and a second connecting post. The first and second connecting posts are respectively movably passed through corresponding mounting holes, and nuts are fixed on both the first and second connecting posts by thread engagement. One end of the first connecting post is fixed inside the sleeve by thread engagement, and the other end of the sleeve is fixed to the second connecting post by welding. This configuration can adapt to photovoltaic support steel beams with different spacing.

[0008] Furthermore, the first connecting post and the second connecting post have the same diameter, and the structural shapes of both ends of the first connecting post are the same. This arrangement allows the first connecting post to be used independently after the second connecting post and the sleeve are removed.

[0009] Furthermore, the gasket is semi-elliptical in shape, and its flat surface is fixed to the photovoltaic support steel beam by welding. The arc-shaped surface of the gasket is fitted with the corresponding nut. With this configuration, the gasket does not need to be installed on-site when installing the tie rod body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The gasket of this utility model can improve the stability between the tie rod body, the nut and the photovoltaic support steel beam. In addition, since the gasket is directly fixed to the photovoltaic support steel beam, on-site installation is not required when installing the tie rod body.

[0012] 2. The design of the tie rod body of this utility model allows for adjustment of the length of the first connecting column inside the sleeve by rotating the sleeve and the second connecting column according to the spacing of the corresponding photovoltaic bracket steel beams. This makes the overall length of the tie rod body adapt to the spacing of the corresponding photovoltaic bracket steel frame. Furthermore, when the spacing of the photovoltaic bracket steel frames is small, the second connecting column and the sleeve can be removed from the first connecting column, allowing the first connecting column to be used independently.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Please see Figures 1 to 3 As shown, this utility model is a horizontal tie rod applicable to photovoltaic brackets, including a tie rod body 1, a washer 2, a nut 3, and mounting holes 4. The two ends of the tie rod body 1 are respectively provided with corresponding mounting holes 4, which are respectively opened through the corresponding photovoltaic bracket steel beams 5. The washer 2 is provided on both sides of the mounting hole 4, and the washer 2 is fixed to the photovoltaic bracket steel beams 5 by welding. The two ends of the tie rod body 1 are respectively fixed with nuts 3 by thread engagement, and the nuts 3 are respectively fitted with the corresponding washer 2.

[0022] Specifically, the pull rod body 1 includes a first connecting post 11, a sleeve 12, and a second connecting post 13. The first connecting post 11 and the second connecting post 13 are respectively movably passed through corresponding mounting holes 4, and nuts 3 are fixed to the first connecting post 11 and the second connecting post 13 by thread engagement. One end of the first connecting post 11 is fixed inside the sleeve 12 by thread engagement, and the other end of the sleeve 12 is fixed to the second connecting post 13 by welding. In use, the length of the first connecting post 11 inside the sleeve 12 can be adjusted by rotating the sleeve 12 and the second connecting post 13 according to the spacing of the corresponding photovoltaic bracket steel beams 5, so that the overall length of the pull rod body 1 is adapted to the spacing of the corresponding photovoltaic bracket steel frame 5. In addition, when the spacing of the photovoltaic bracket steel frame 5 is small, the second connecting post 13 and the sleeve 12 can be removed from the first connecting post 11, and the first connecting post 11 can be used alone.

[0023] Specifically, the first connecting post 11 and the second connecting post 13 have the same diameter, and the two ends of the first connecting post 11 have the same structural shape. When in use, after the second connecting post 13 and the sleeve 12 are removed, the first connecting post 11 is used alone.

[0024] Specifically, the gasket 2 is semi-elliptical in shape, and the flat surface of the gasket 2 is fixed to the photovoltaic support steel beam 5 by welding. The arc-shaped surface of the gasket 2 is fitted with the corresponding nut 3. In use, the semi-elliptical gasket 2 can improve the stability between the tie rod body 1, the nut 3 and the photovoltaic support steel beam 5. In addition, since the gasket 2 is directly fixed to the photovoltaic support steel beam 5, on-site installation is not required when installing the tie rod body 1.

[0025] Please see Figure 1-3 As shown, this utility model is a horizontal tie rod applicable to photovoltaic brackets. Its working principle is as follows: When in use, firstly, adjust the length of the tie rod body 1 according to the spacing of the corresponding photovoltaic bracket steel beams 5, then pass the tie rod body 1 through the corresponding mounting holes 4, and then fix nuts 3 at both ends of the tie rod body 1, thereby preventing the position of the photovoltaic bracket steel beams 5 from changing through the nuts 3.
