Description

Technical Field

[0001] This application relates to the technical field of solar brackets, and particularly to a purlin and a photovoltaic tracking bracket. Background Art

[0002] In the photovoltaic power station project, the pile foundation project and installation project of the photovoltaic bracket are the parts with the largest civil engineering and mechanical and electrical engineering quantities in the whole photovoltaic power station. The purlin system in the photovoltaic bracket system is an important node, which is responsible for installing the photovoltaic modules on the overall tracking bracket. The time consumed for installing the purlins and photovoltaic modules accounts for about 30% of the total time for installing a row of brackets, and the labor cost accounts for a large proportion. Reducing the difficulty of installing the photovoltaic modules on the purlins and improving the installation efficiency to realize the quick installation plan of the photovoltaic tracking bracket is one of the trends in high-labor-cost areas. Currently, purlins generally need to be equipped with other hooks and positioning parts. There are many overall moving parts and they are cumbersome, which is not convenient for operators to position and install. There are many parts with great operation difficulty, which greatly reduces the installation efficiency.

[0034] Next, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments described herein.

[0035] As one aspect of the present application, a purlin is provided.

[0036] As Figures 1-6 shown, the purlin of the embodiment of the present application is mounted on the rectangular tube 3 and is used to connect the photovoltaic module 4 so as to mount the photovoltaic module 4 on the rectangular tube 3.

[0037] The purlin includes a purlin body 1, a first mounting plate 11, a second mounting plate 12 and at least one set of connection components; the purlin body 1 has a mounting cavity 14, and the mounting cavity 14 adopted in the embodiment of the present application is in a "U" shape. The purlin body 1 is connected to the rectangular tube 3 by screws. The bottom of the mounting cavity 14 has screw holes, and the screws pass through the screw holes to connect to the rectangular tube 3. One side of the first mounting plate 11 is integrally connected to the top of the purlin body 1 and is close to the opening of the mounting cavity 14, and the other side extends away from the purlin body 1. One side of the second mounting plate 12 is integrally connected to the top of the purlin body 1 and is close to the opening of the mounting cavity 14, and the other side extends away from the purlin body 1. The first mounting plate 11 and the second mounting plate 12 are located on both sides of the purlin body 1, that is, the mounting cavity 14 is located between the first mounting plate 11 and the second mounting plate 12. The purlin body 1 is used to connect the rectangular tube 3 and the connection components, and the connection components are used to connect the photovoltaic module 4.

[0038] The number of sets of connection components is not limited. In this embodiment, one set of connection components is adopted, and the connection components are arranged in the middle of the purlin. The connection components include a first hanging piece 21 and a second hanging piece 22 spaced on the first mounting plate 11, and the direction of the first hanging piece 21 facing the second hanging piece 22 is the same as the length direction of the first mounting plate 11. A first mounting opening 23 for accommodating the frame 41 of the photovoltaic module 4 is formed between the first hanging piece 21 and the second hanging piece 22 for hanging the frame 41 of the photovoltaic module 4. The connection components further include a third hanging piece 24 and a fourth hanging piece 25 spaced on the second mounting plate 12, and the direction of the third hanging piece 24 facing the fourth hanging piece 25 is the same as the direction of the second mounting plate 12. A second mounting opening 26 is formed between the third hanging piece 24 and the fourth hanging piece 25 for hanging the frame 41 of another photovoltaic module 4. In this embodiment, the first hanging piece 21 and the second hanging piece 22 are integrally connected to the first mounting plate 11, and both are perpendicular to the first mounting plate 11. The third hanging piece 24 and the fourth hanging piece 25 are integrally connected to the second mounting plate 12, and both are perpendicular to the second mounting plate 12.

[0039] In this embodiment, when installed at a large angle, the end of the frame 41 of the photovoltaic module 4 can be directly hung on the connection component of the purlin to prevent the photovoltaic module 4 from sliding down. The frame 41 of the photovoltaic module 4 is hung on the purlin body 1 through the connection component. During the hanging process, only the end parts of the frame 41 of the photovoltaic module 4 need to be inserted into the first installation opening 23 and the second installation opening 26 respectively. At this time, the first hanging piece 21 and the second hanging piece 22 are in contact with one of the frames 41, and the third hanging piece 24 and the fourth hanging piece 25 are both in contact with the other frame 41, so as to limit the frame 41 and make it stably hung on the purlin; the purlin structure of this application embodiment is simple, with very few overall moving parts, greatly reducing the number of components, realizing rapid installation, and significantly improving the installation efficiency and reducing the labor cost.

[0040] In an alternative embodiment, the third hanging piece 24 is correspondingly arranged with the first hanging piece 21, and the fourth hanging piece 25 is correspondingly arranged with the second hanging piece 22. Therefore, the first hanging piece 21, the second hanging piece 22, the third hanging piece 24 and the fourth hanging piece 25 are distributed in a rectangular shape on the purlin.

[0041] In this embodiment, since the third hanging piece 24 is correspondingly arranged with the first hanging piece 21, and the fourth hanging piece 25 is correspondingly arranged with the second hanging piece 22, adjacent two photovoltaic modules 4 can be symmetrically installed on the purlin, which is convenient and fast to install and the purlin is stressed evenly and stably, further improving the installation efficiency and installation stability of the photovoltaic module 4.

[0042] In an alternative embodiment, positioning holes 13 are provided on both the first mounting plate 11 and the second mounting plate 12. A positioning portion protrudes from the periphery of the positioning hole 13, and the positioning hole 13 is located in the positioning portion; the bottom of the frame 41 of the photovoltaic module 4 has mounting holes, and the positioning portion can be located in the mounting holes. It should be noted that in this embodiment, the number of the positioning holes 13 is not limited, and the number of the positioning holes 13 is the same as that of the mounting holes. When the photovoltaic module 4 is installed on the purlin, the positioning portion is located in the mounting hole at this time. The setting of the positioning portion can achieve the function of accurately positioning the photovoltaic module 4 after it is moved left and right, without the need to additionally increase a positioning device.

[0043] The difference from the above embodiment is that as Figure 5 shown, in this purlin, the connection component is detachably arranged on the purlin body 1. The first hanging piece 21 and the second hanging piece 22 are connected through a first fixing portion, and the first fixing portion is detachably connected to the first mounting plate 11; the third hanging piece 24 and the fourth hanging piece 25 are connected through a second fixing portion, and the second fixing portion is detachably connected to the second mounting plate 12.

[0044] In this embodiment, the first hanging piece 21 and the second hanging piece 22 are detachably linked to the first mounting plate 11 through the first fixing portion, and the third hanging piece 24 and the fourth hanging piece 25 are detachably linked to the second mounting plate 12 through the second fixing portion. It can be seen from this that when the first hanging piece 21, the second hanging piece 22, the third hanging piece 24 and the fourth hanging piece 25 are damaged due to long-term use, they can be replaced, effectively improving the service life of the purlin.

[0045] In an alternative embodiment, the first fixing portion includes a first connecting piece 271 and a first fixing piece 272 connected to the purlin body 1. The first hanging piece 21 and the second hanging piece 22 are connected to the first fixing piece 272 through the first connecting piece 271, and the first connecting piece 271 is attached to the first mounting plate 11. Among them, the first connecting piece 271 and the first fixing piece 272 are perpendicularly arranged, and both the first hanging piece 21 and the second hanging piece 22 are perpendicular to the first connecting piece 271, so that both the first hanging piece 21 and the second hanging piece 22 are parallel to the first fixing piece 272.

[0046] The second fixing portion includes a second connecting piece 281 and a second fixing piece 282 connected to the purlin body 1. The third hanging piece 24 and the fourth hanging piece 25 are connected to the second fixing piece 282 through the second connecting piece 281, and the second connecting piece 281 is attached to the second mounting plate 12. Among them, the second connecting piece 281 and the second fixing piece 282 are perpendicularly arranged, and both the third hanging piece 24 and the fourth hanging piece 25 are perpendicular to the second connecting piece 281, so that both the third hanging piece 24 and the fourth hanging piece 25 are parallel to the second fixing piece 282. The purlin body 1 is located between the first fixing piece 272 and the second fixing piece 282, and the first fixing piece 272 and the second fixing piece 282 are fixed to the purlin body 1 through a fixing member 29.

[0047] In this embodiment, the first hanging piece 21 and the second hanging piece 22 are connected to the first fixing piece 272 through the first connecting piece 271, so that the first hanging piece 21 and the second hanging piece 22 are in a whole, which is convenient and fast during the installation process, and effectively improves the installation efficiency of the first hanging piece 21 and the second hanging piece 22; at the same time, since the first connecting piece 271 is arranged in a fitting manner with the first mounting plate 11 and the two are parallel to each other, it plays a role in strengthening the load-bearing of the first mounting plate 11, and further improves the load-bearing strength of the first mounting plate 11. The third hanging piece 24 and the fourth hanging piece 25 are connected to the second fixing piece 282 through the second connecting piece 281, so that the third hanging piece 24 and the fourth hanging piece 25 are in a whole, which is convenient and fast during the installation process, and effectively improves the installation efficiency of the third hanging piece 24 and the fourth hanging piece 25; at the same time, since the second connecting piece 281 is arranged in a fitting manner with the second mounting plate 12 and the two are parallel to each other, it plays a role in strengthening the load-bearing of the second mounting plate 12, and further improves the load-bearing strength of the second mounting plate 12. In addition, since the first fixing piece 272 and the second fixing piece 282 are fixed to the purlin body 1 through the fixing member 29, when it is necessary to replace the first fixing piece 272 and the second fixing piece 282, only the fixing member 29 needs to be removed from the purlin body 1, and then the other first fixing piece 272 and the second fixing piece 282 are reinstalled to the purlin body 1 through the fixing member 29.

[0048] In an alternative embodiment, the fixing member 29 includes a fixing screw and a fixing nut, and the fixing nut has a thread. The fixing screw has a nut and a screw rod, and an external thread is provided on the circumferential side of the screw rod. One end of the screw rod of the fixing screw away from the nut sequentially passes through the second fixing piece 282, the purlin body 1, the first fixing piece 272 and is threadedly connected to the fixing nut, thereby realizing the detachable connection of the first fixing piece 272 and the second fixing piece 282 to the purlin body 1.

[0049] In an alternative embodiment, a fixing sleeve 30 is sleeved on the fixing screw, that is, the fixing sleeve 30 is sleeved on the screw rod. The fixing sleeve 30 is located in the installation cavity 14, one end of the fixing sleeve 30 abuts against the inner side wall of the installation cavity 14, and the other end abuts against the other inner side wall of the installation cavity 14.

[0050] In this embodiment, during the installation process of the first fixing piece 272 and the second fixing piece 282, if the fixing screw is screwed too much, both ends of the fixing sleeve 30 will exert forces on both sides of the installation cavity 14 to prevent the purlin body 1 from deforming. Therefore, the setting of the fixing sleeve 30 effectively improves the situation that the purlin body 1 is deformed due to excessive screwing of the fixing screw.

[0051] The difference from the above embodiment is that, as Figures 6-7As shown, in this purlin, the first hanging piece 21 has a first clamping interface 273 that can be entered, the second hanging piece 22 has a second clamping interface 274 that can be entered, and the first clamping interface 273 and the second clamping interface 274 are opened towards each other; the third hanging piece 24 has a third clamping interface 283 that can be entered, the fourth hanging piece 25 has a fourth clamping interface 284 that can be entered, and the third clamping interface 283 and the fourth clamping interface 284 are opened towards each other.

[0052] In this embodiment, when the photovoltaic module 4 is installed on the purlin at a large angle, in extreme environments, such as in strong winds, if only the end of the frame 41 of the photovoltaic module 4 is hung on the first installation opening 23 and the second installation opening 26, it is easy to blow up the photovoltaic module 4 when the wind blows, so that it disengages from the purlin and is difficult to install in extreme weather. Therefore, the openings of the first clamping interface 273, the second clamping interface 274, the third clamping interface 283 and the fourth clamping interface 284 enable a part of the frame 41 of the photovoltaic module 4 to be respectively clamped in the first clamping interface 273, the second clamping interface 274, the third clamping interface 283 and the fourth clamping interface 284, which can limit the frame 41 of the photovoltaic module 4, thereby reducing the situation that the photovoltaic module 4 is blown up by strong winds, further improving the installation efficiency, installation stability and ensuring the safety of installation workers.

[0053] In summary, the structure of the purlin in the embodiment of the present application is simple and integrates multiple functions. Compared with the traditional purlin structure, its installation parts are greatly reduced, which can significantly improve the installation efficiency of the photovoltaic module 4 and reduce the labor cost. The structure of the connecting component of the purlin is simple to process. When the photovoltaic module 4 is installed on the purlin at a large angle, the end of the frame 41 of the photovoltaic module 4 can be directly hung on the connecting component of the purlin body 1 to prevent the photovoltaic module 4 from sliding down. In addition, several positioning holes 13 are provided at the part of the purlin body 1 in contact with the bottom surface of the frame 41 of the photovoltaic module 4. The positioning holes 13 correspond to the installation holes on the frame 41 of the photovoltaic module 4, and the positioning parts on the positioning holes 13 can be located in the installation holes to achieve the function of accurate positioning after the photovoltaic module 4 is moved left and right.

[0054] As the second aspect of the present invention, a photovoltaic tracking bracket is provided. The photovoltaic tracking bracket includes a rectangular tube 3, a column and the purlin provided in any of the above embodiments. The purlin is connected to the rectangular tube 3, and the rectangular tube 3 is connected to a column (not shown in the figure).
