Description

[0002] In the installation process of photovoltaic modules, in the face of the present situation of photovoltaic module frame height diversification, it is necessary to match different specifications of pressure codes to ensure that the module can be stably and effectively fixed on the to-be-installed guide rail. However, this approach also brings a series of challenges. First of all, different heights of the frame mean that multiple specifications of pressure codes need to be prepared, which not only increases the types of bracket materials, but also makes inventory management complex. Field construction personnel need to carefully check the frame height of each component and select the corresponding pressure code for installation, which greatly increases the complexity of work and the risk of errors.

[0003] Secondly, the installation direction of photovoltaic modules also needs to be adjusted according to actual needs during on-site installation. Especially in large-scale photovoltaic power station construction projects, multiple specifications of pressure codes need to be prepared, but multiple materials are mixed together, which can easily lead to installation errors or delays in construction period if there is no good organization and management. In addition, frequent replacement of pressure code specifications also reduces the operation efficiency of construction personnel because they need to constantly adapt to the installation methods and skills of different specifications of pressure codes.

[0037] The lower end of the pressing code connector 31 is clamped to the upper end of the to-be-installed guide rail 200, the pressing code connector 31, the pressing code direction adjusting piece 32 and the pressing code height adjusting piece 33 are sequentially installed on the to-be-installed guide rail 200 from bottom to top through the pressing code fastener 34, and the pressing code direction adjusting piece 32 and the pressing code height adjusting piece 33 can form four direction settings with the to-be-installed guide rail 200 with the pressing code fastener 34 as the pivot;

[0038] The pressing code direction adjusting piece 32 includes a pressing code pressing part 321 and a pressing code position adjusting part 322, one side of the pressing code pressing part 321 is fixedly connected with the pressing code position adjusting part 322, the pressing code pressing part 321 and the pressing code position adjusting part 322 are vertically arranged, the pressing code pressing part 321 is rotatably installed on the upper end of the pressing code connector 31 with the pressing code fastener 34 as the pivot, the inner side surface of the pressing code position adjusting part 322 abuts against the side surface of the pressing code connector 31 in one direction, and the outer side surface of the pressing code position adjusting part 322 is protrusively provided with a plurality of pressing code height clamping teeth 323;

[0039] The pressing code height adjusting piece 33 includes a pressing code pressing plate 331 and a pressing code height adjusting part 332, one side of the pressing code pressing plate 331 is fixedly connected with the pressing code height adjusting part 332, the pressing code pressing plate 331 and the pressing code height adjusting part 332 are vertically arranged, the bottom end of the pressing code height adjusting part 332 is protrusively provided with a pressing code fixed clamping tooth 333, the pressing code fixed clamping tooth 333 can abut against the guide rail surface of the to-be-installed guide rail 200 or abut against one of the pressing code height clamping teeth 323, so that the pressing code pressing plate 331 and part of the guide rail surface of the to-be-installed guide rail 200 form a pressing code placing cavity 30 with different heights, and the pressing code placing cavity 30 is used for placing a photovoltaic module.

[0040] As Figures 1-2 shown, the working principle of the universal pressing code 3 is based on the flexible matching and adjusting function between its components, aiming to adapt to the installation requirements of photovoltaic modules with different heights and angles. The specific working principle is as follows:

[0041] Firstly, the pressing code connector 31 is clamped to the upper end of the to-be-installed guide rail 200 to form preliminary fixation, serving as the basic support of the entire pressing code device.

[0042] Then, the code direction adjusting piece 32 and the code height adjusting piece 33 are sequentially installed on the code connecting piece 31, and the code connecting piece 31, the code direction adjusting piece 32 and the code height adjusting piece 33 are sequentially installed on the to-be-installed guide rail 200 from bottom to top by sequentially penetrating the corresponding hole positions with the code fastener 34, wherein the code pressing part 321 of the code direction adjusting piece 32 can rotate relative to the code connecting piece 31 and the to-be-installed guide rail 200 with the code fastener 34 as the pivot, so as to adjust the installation direction between the code position adjusting part 322 and the to-be-installed guide rail 200, as shown in Figures 3-4 The inner side of the code position adjusting part 322 abuts against the code connecting piece 31, and the outer side is provided with the code height clamping tooth 323, which allows the code direction adjusting piece 32 to be flexibly adjusted in direction while maintaining a certain stability.

[0043] Secondly, the code pressing plate 331 of the code height adjusting piece 33 is vertically arranged with the code height adjusting part 332, and the code placing cavity 30 is formed between the code pressing plate and the upper end of the to-be-installed guide rail 200, and the code fixing clamping tooth 333 at the bottom end of the code height adjusting part 332 can be selectively clamped with different code height clamping teeth 323 on the code direction adjusting piece 32. Only need to place the to-be-installed photovoltaic module in the code placing cavity 30, and according to the height of the photovoltaic module, the code fixing clamping tooth 333 selects the clamping tooth of appropriate height for clamping, so as to adjust the height of the code placing cavity 30 formed between the code pressing plate 331 and the upper end of the to-be-installed guide rail 200, as shown in Figures 5-7 .

[0044] Finally, after determining the installation direction and installation height of the to-be-installed photovoltaic module on the to-be-installed guide rail, the pressing effect of the code pressing plate 331 and the fastening effect of the code fastener are used to ensure that the photovoltaic module is stably installed on the to-be-installed guide rail 200.

[0045] In summary, the beneficial effects of the general code 3 are as follows:

[0046] 1. Strong flexibility: through the flexible cooperation of the code direction adjusting piece and the code height adjusting piece, the installation requirements of photovoltaic modules of different heights and angles can be effectively adapted, and the flexibility and universality of installation are improved.

[0047] 2. Simple structure: the entire device is composed of a small number of basic components, and the design is simple and clear, which is convenient for production, installation and maintenance.

[0048] 3. Easy to operate: users only need to perform simple rotating and clamping operations to quickly complete the angle and height adjustment of the photovoltaic module, which greatly reduces the installation difficulty and time cost.

[0049] 4. Improve installation efficiency: because the installation process is simple and fast, and can be adapted to a variety of specifications photovoltaic module at one time, so it can significantly improve the installation efficiency of photovoltaic system.

[0050] 5. High cost-effective: the pressure code device is low in cost, easy to popularize and promote, which helps to reduce the overall construction cost of photovoltaic system and improve the economic benefit of the project.

[0051] Further illustrate, the cross section of the to-be-installed guide rail 200 is concave, and two first guide rail clamping portions 2003 are arranged at the upper end notches of the to-be-installed guide rail 200, the first guide rail clamping portions 2003 are arranged opposite to each other and are not connected, and the upper end notches of the to-be-installed guide rail 200 and the two first guide rail clamping portions 2003 form a clamping groove.

[0052] The pressure code connecting piece 31 comprises a pressure code connecting fixed portion 311.

[0053] The lower ends of the pressure code connecting fixed portion 311 are respectively extended to be provided with pressure code connecting clamping portions 312, and the pressure code connecting clamping portions 312 are clamped with the clamping groove.

[0054] As shown in Figure 2 , 5 -7, after further refining the design of the pressure code connecting piece 31, the pressure code connecting piece 31 comprises a pressure code connecting fixed portion 311 and pressure code connecting clamping portions 312 respectively extended from the lower ends of the fixed portion 331. This design makes the pressure code connecting piece 31 more stably clamped with the clamping groove of the to-be-installed guide rail 200, thereby enhancing the stability and reliability of the pressure code connecting piece 31 and the to-be-installed guide rail 200. The specific working principle is as follows:

[0055] The pressure code connecting fixed portion 311 serves as the main part of the pressure code connecting piece 31, responsible for bearing and transmitting the pressing force from the pressure code direction adjusting piece 32, the pressure code height adjusting piece 33 and the pressure code fastener 34. At the same time, it also provides a stable support foundation for the pressure code connecting clamping portion 312. The pressure code connecting clamping portion 312 is respectively extended from the lower ends of the pressure code connecting fixed portion 311, and its shape and size are matched with the clamping groove of the guide rail. In the installation process, the pressure code connecting clamping portion 312 is inserted and clamped in the clamping groove, forming a stable mechanical connection.

[0056] Further illustrate, the pressure code connecting clamping portion 312 comprises a pressure code connecting clamping hook 313, and the pressure code connecting clamping hook 313 is outwardly protrudingly arranged along the extension direction of the pressure code connecting clamping portion 312.

[0057] As shown in Figure 2 , 5As shown in Figure 7, after a detailed description of the design of the compression code connection clamp portion 312 of the compression code connector 31, its operating principle can be further understood. The compression code connection clamp portion 312 includes a compression code connection hook 313, which protrudes outward along the extension direction of the compression code connection clamp portion 312. This design enables the compression code connection clamp portion 312 to more effectively engage with the engagement groove of the guide rail 200 to be installed, enhancing the stability and reliability of the connection.

[0058] First, the key components of the code-pressing connection hooks 313 are the key components of the code-pressing connection clamp 312. They protrude outward, creating a "barbed" effect. As the code-pressing connection clamp 312 is inserted into the engagement groove, the code-pressing connection hooks 313 gradually expand and contact the sidewalls of the engagement groove as the code-pressing connection clamp 312 moves deeper, ultimately fully engaging the clamp. These code-pressing connection hooks 313 can tightly engage the sidewalls of the engagement groove, forming a mechanical lock.

[0059] More importantly, due to the protruding design of the code connection hook 313, they can provide additional resistance when subjected to external force, preventing the code connection clamp 312 from accidentally falling out of the clamping groove. This design significantly improves the stability and reliability of the connection.

[0060] To further illustrate, a code-enhancing resistance pattern 314 is provided inside the code-enhancing connection card portion 312 .

[0061] like Figure 2 、 5 As shown in FIG-7 , the compression code resistance-enhancing lines 314 are a series of uneven textures or grooves engraved or pressed inside the compression code connection clamp 312. These compression code resistance-enhancing lines 314 can generate additional friction when in contact with the compression code fastener 34, preventing the compression code fastener 34 from sliding or disengaging when subjected to external forces, thereby further enhancing the stability and reliability of the connection.

[0062] To further explain, the coding plate 331 has a plurality of coding serrations 334 on the side facing the guide rail 200 to be installed, and the plurality of coding serrations 334 extend in the horizontal direction of the coding plate 331 , and the coding serrations 334 at the end do not exceed the installation position of the coding fastener 34 .

[0063] like Figure 2 、 5 As shown in Figure 7, in the design of the code height adjustment member 33, a plurality of code serrations 334 are provided on the side of the code pressing plate 331 facing the guide rail 200 to be installed. These code serrations extend horizontally along the code pressing plate 331. The working principle of this design is mainly reflected in the following aspects:

[0064] When the press code pressing plate 331 is fastened on the photovoltaic module to be installed, the press code sawtooth 334 on it will be in close contact with the surface of the photovoltaic module, forming multiple biting points. These biting points not only increase the friction between the press code pressing plate 331 and the photovoltaic module, but also make the position of the press code 331 on the photovoltaic module more stable and less likely to slip or loosen due to external forces.

[0065] Secondly, the design of the press code sawtooth 334 enables the press code pressing plate 331 to fit the guide rail surface more accurately, especially when fine-tuning the position of the photovoltaic module is needed. The user can adjust the position of the photovoltaic module so that the press code sawtooth 334 on the press code pressing plate 331 aligns with a specific position of the photovoltaic module, and then fasten the press code pressing plate 331 and the photovoltaic module firmly on the guide rail 200 to be installed by the press code fastener 34 such as screws, bolts, etc.

[0066] Finally, the press code sawtooth 334 located at the end of the press code pressing plate 331 is specially designed not to exceed the installation position of the press code fastener 34. This design ensures that the press code fastener 34 is not interfered by the press code sawtooth 334 during installation, thereby ensuring the smooth installation and effective fastening of the press code fastener 34. At the same time, it also avoids unnecessary wear and tear or damage to the press code fastener 34 caused by the press code sawtooth 334.

[0067] Further explanation, the side of the press code pressing plate 331 facing the guide rail 200 to be installed is convexly provided with a press code protection part 335, the convex height of the press code protection part 335 is higher than the convex height of the press code sawtooth 334, the press code protection part 335 is located close to the press code sawtooth 334 at the end, and the press code protection part 335 does not exceed the installation position of the press code fastener 34.

[0068] As shown in Figure 2 , 5 -7, in the further refinement of the design of the press code height adjustment part 33, the side of the press code pressing plate 331 facing the guide rail 200 to be installed is not only provided with a plurality of press code sawtooth 334, but also convexly provided with a press code protection part 335. The working principle of this design mainly embodies in the following aspects:

[0069] The main function of the press code protection part 335 is to protect the press code fastener 34 located nearby from external damage. Since the press code fastener 34 such as screws, bolts, etc. is the key component connecting the press code pressing plate 331 and the guide rail 200 to be installed, its integrity and stability are crucial to the installation of the entire photovoltaic module. The press code protection part 335 reduces the risk of accidental collision or scratching of the press code fastener 34 during installation, use and maintenance through physical isolation.

[0070] More importantly, the code protection part 335 is arranged close to the code sawtooth 334 at the end, and the design does not exceed the installation position of the code fastener 34. This layout ensures that the code protection part 335 provides protection while also providing positioning for the photovoltaic module to be installed, as the protruding height of the code protection part 335 is higher than the protruding height of the code sawtooth 334. The photovoltaic module can abut against the code protection part 335 without worrying about colliding with the code fastener 34.

[0071] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for the purpose of explaining the principles of the present application, and cannot be interpreted in any way as a limitation on the scope of protection of the present application. Based on the explanations herein, those skilled in the art can conceive of other specific embodiments of the present application without having to exert creative effort, and these equivalent variations or replacements are all included within the scope defined by the claims of the present application.
