Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support joint structure and a photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting systems, as a crucial component of solar power generation systems, are widely used in rooftops, ground-mounted installations, and agriculture. They not only stably support the photovoltaic panels but also maximize solar energy absorption efficiency through optimized angles and orientations, providing key support for the effective utilization of clean energy. With the development of photovoltaic technology, to maximize the installation area of ​​PV mounting systems, the length of the main shafts has been continuously increasing, typically reaching 40 or 60 meters, or even longer. For ease of production and transportation, these longer main shafts are generally divided into several sections, which are then assembled at the PV power plant site.

[0003] Spindles are typically hollow, and common connection methods include bolted connections or on-site welding. Taking a bolted connection as an example, the process usually involves creating a through hole in one spindle and a corresponding through hole in the other spindle to be connected, along with a connecting rod with a through hole. During installation, both ends of the connecting rod are inserted into the two spindles respectively, and then bolts are passed through the corresponding through holes on the connecting rod and the spindles and tightened to achieve a secure connection between the two spindles.

[0004] However, this bolted connection method faces a challenge in practice: manually aligning the through holes on the connecting rod and the spindle is difficult, often requiring multiple adjustments to ensure accurate hole alignment for bolt insertion. This process is time-consuming and challenging, significantly reducing overall installation efficiency. Utility Model Content

[0005] To address the technical problems of high installation difficulty and low installation efficiency in existing technologies, this utility model provides a photovoltaic bracket joint structure and photovoltaic bracket that are simple to install and have high installation efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The photovoltaic support connector structure includes a first hollow shaft, a second hollow shaft, a connecting rod, and bolts. The first hollow shaft has a first through hole at its first end, and the second hollow shaft has a second through hole at its first end. Both ends of the connecting rod have third through holes. One end of the connecting rod is inserted into the first end of the first hollow shaft, and the other end is inserted into the first end of the second hollow shaft, aligning the first and third through holes for bolt insertion. The inner wall of the first hollow shaft has a first limiting member, and the inner wall of the second hollow shaft has a second limiting member. When both the first and second limiting members abut against the connecting rod, they restrict the axial movement of the connecting rod, and at this time, the first and third through holes are aligned, and the second and third through holes are aligned.

[0008] Furthermore, including the first limiting block, the first hollow shaft has a first groove on its circumference, and the first limiting member is formed by the first limiting block being inserted into the first hollow shaft through the first groove.

[0009] Furthermore, the first limiting block is L-shaped, with one end inserted into the first hollow shaft and the other end having a first mating through hole. The first mating through hole is aligned with the first through hole to allow bolts to pass through.

[0010] Furthermore, including a second limiting block, a second groove is provided on the circumference of the second hollow shaft, and the second limiting member is formed by the second limiting block being inserted into the interior of the second hollow shaft through the second groove.

[0011] Furthermore, the second limiting block is L-shaped, with one end inserted into the second hollow shaft and the other end having a second mating through hole. The second mating through hole is aligned with the second through hole to allow bolts to pass through.

[0012] Furthermore, the second groove is a strip-shaped groove, and the second limiting block can slide in the strip-shaped groove. When the second limiting block slides towards the direction of the first hollow shaft, it pushes the connecting rod to slide in the first hollow shaft and the second hollow shaft until the connecting rod abuts against the first limiting member, thereby restricting the axial movement of the connecting rod. At this time, the first mating through hole, the first through hole and the third through hole are aligned, and the second mating through hole, the second through hole and the third through hole are aligned.

[0013] Furthermore, the first hollow shaft, the second hollow shaft, and the connecting rod are square tubes.

[0014] This utility model also provides a photovoltaic support structure, including the photovoltaic support joint structure described in any of the above embodiments.

[0015] Furthermore, it also includes a column, a telescopic push rod mechanism, a crossbeam, a mounting frame, and positioning components. The column is vertically positioned, and the crossbeam is horizontally positioned. The top of the column is equipped with a hinged support, and the crossbeam is rotatably connected to the hinged support. The mounting frame is fixedly installed on the crossbeam, and photovoltaic panels are installed on the mounting frame. One end of the telescopic push rod mechanism is hinged to the column, and the other end of the telescopic push rod mechanism is hinged to the mounting frame. The telescopic push rod mechanism pushes the mounting frame to swing back and forth around the central axis of the hinged support. The front and rear sides of the mounting frame are provided with slots, and the positioning components have corresponding locking blocks that are inserted into the slots. The positioning components are used to limit the front and rear sides of the photovoltaic panels.

[0016] The beneficial effects of this utility model are:

[0017] By setting a first limiting member inside the first hollow shaft and a second limiting member inside the second hollow shaft, and inserting both ends of the connecting rod into the first and second hollow shafts respectively, the axial movement of the connecting rod can be restricted when both the first and second limiting members abut against the connecting rod. At this time, the first and third through holes are aligned, and the second and third through holes are also aligned. Bolts are then passed through the first and third through holes, and tightened to achieve fixation. This quick installation method reduces the time cost of repeatedly adjusting the position of the connecting rod in traditional installation processes, reduces installation difficulty, and significantly improves overall assembly speed and work efficiency.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0025] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixation," etc., should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 5 As shown, this utility model provides a photovoltaic bracket connector structure and a photovoltaic bracket.

[0029] like Figures 1 to 3 As shown, the photovoltaic support connector structure includes a first hollow shaft 1, a second hollow shaft 2, a connecting rod 3, and a bolt 4. The first hollow shaft 1 has a first through hole 5 at its first end, the second hollow shaft 2 has a second through hole 6 at its first end, and the connecting rod 3 has a third through hole 7 at both ends. One end of the connecting rod 3 is inserted into the first end of the first hollow shaft 1, and the other end of the connecting rod 3 is inserted into the first end of the second hollow shaft 2, so that the first through hole 5 and the third through hole 7 are aligned, and the second through hole 6 and the third through hole 7 are aligned, for the bolt 4 to pass through. The inner wall of the first hollow shaft 1 has a first limiting member, and the inner wall of the second hollow shaft 2 has a second limiting member. When both the first limiting member and the second limiting member abut against the connecting rod 3, the axial movement of the connecting rod 3 can be restricted, and at this time the first through hole 5 and the third through hole 7 are aligned, and the second through hole 6 and the third through hole 7 are aligned.

[0030] For the first hollow shaft 1, the second hollow shaft 2 and the connecting rod 3, square tubes are preferred in this scheme. Of course, round tubes or tubes of other shapes can also be used. When using round tubes, the connecting rod 3 should be prevented from rotating inside the first hollow shaft 1 and the second hollow shaft 2 to avoid difficulty in aligning the first through hole 5 with the third through hole 7, and the second through hole 6 with the third through hole 7.

[0031] The inner wall of the first hollow shaft 1 has a first limiting member. The first limiting member can be a protrusion formed on the inner wall of the first hollow shaft 1, or it can be a first limiting block 8. A first groove 9 is opened on the circumference of the first hollow shaft 1. The first limiting member is formed by the first limiting block 8 being inserted into the first hollow shaft 1 through the first groove 9, which facilitates manufacturing. Regarding the fit between the first groove 9 and the first limiting block 8, the size of the first groove 9 can be larger than the size of the first limiting block 8, allowing the first limiting block 8 to move within the first groove 9. The first limiting block 8 can be easily inserted into the first groove 9. When installing and limiting the connecting rod 3, it is necessary to hold the first limiting block 8 by hand. After the bolt 4 is inserted, the first limiting block 8 can be removed. Alternatively, the first limiting block 8 can be interference-fitted with the first concave side 9, with the first limiting block 8 snapping into the first groove 9. In this case, there is no need for manual support of the first limiting block 8, and the first limiting block 8 will not fall off.

[0032] Similarly, the second limiting member can be set in accordance with the first limiting member. That is, the second limiting member can be a protrusion formed on the inner wall of the second hollow shaft 2, or it can be a second limiting block 10. The second hollow shaft 2 has a second groove 11 on its circumference. The second limiting member is formed by the second limiting block 10 being inserted into the second hollow shaft 2 through the second groove 11, which facilitates manufacturing. For the fit between the second groove 11 and the second limiting block 10, the size of the second groove 11 can be larger than the size of the second limiting block 10. The second limiting block 10 can move within the second groove 11 and can be easily inserted into the second groove 11. When installing and limiting the connecting rod 3, it is necessary to hold the second limiting block 10 by hand. After the bolt 4 is inserted, the second limiting block 10 can be removed. Alternatively, the second limiting block 10 can be interference-fitted with the second groove 11, and the second limiting block 10 is inserted into the second groove 11. At this time, there is no need to manually support the second limiting block 10, and the second limiting block 10 will not fall off.

[0033] like Figures 1 to 3As shown, regarding the relative positions of the first groove 9 and the first through hole 5, when the first hollow shaft 1 is placed horizontally, the first end of the first hollow shaft 1 is located on the right side. Preferably, the first groove 9 is located on the left side of the first through hole 5. At this time, the first limiting block 8 abuts against one end of the connecting rod 3, thereby limiting the connecting rod 3. Alternatively, the first groove 9 can be located on the right side of the first through hole 5. In this case, a clearance groove is provided on the connecting rod 3 to avoid the first limiting block 8. The connecting rod 3 slides to the left. When the first limiting block 8 abuts against the side wall of the clearance groove, the connecting rod 3 stops moving, and the first through hole 5 and the third through hole 7 are aligned. Similarly, the relative positions of the second groove 11 and the second through hole 6 can also be designed in the above manner.

[0034] Furthermore, the first limiting block 8 can be designed in an L-shape, with one end inserted into the first hollow shaft 1 and the other end having a first mating through hole aligned with the first through hole 5. Bolts 4 are then inserted to fix the first limiting block 8 onto the first hollow shaft 1, preventing it from falling off and facilitating installation. Similarly, the second limiting block 10 can also be designed in an L-shape, with one end inserted into the second hollow shaft 2 and the other end having a second mating through hole aligned with the second through hole 6. Bolts 4 are then inserted to secure it.

[0035] like Figures 1 to 3 As shown, preferably, the second groove 11 is designed as a strip groove, and the second limiting block 10 can slide within the strip groove. When the second limiting block 10 slides towards the first hollow shaft 1, it pushes the connecting rod 3 to slide within the first hollow shaft 1 and the second hollow shaft 2 until the connecting rod 3 abuts against the first limiting member. At this time, the relative position of the connecting rod 3 is fixed, and the first mating through hole, the first through hole 5, and the third through hole 7 are aligned, as are the second mating through hole, the second through hole 6, and the third through hole 7. With this design, the connecting rod 3 can be directly pushed to slide using the second limiting block 10. Compared to pushing the connecting rod 3 by hand, this solution is more convenient and labor-saving, while also achieving rapid positioning.

[0036] This utility model also provides a photovoltaic bracket, including the photovoltaic bracket joint structure described in any of the above embodiments. The specific structure of the photovoltaic bracket joint structure is as described in the above embodiments. Since this photovoltaic bracket adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0037] like Figure 4 and Figure 5As shown, in this embodiment of the solution, there are columns 12, telescopic push rod mechanisms 13, crossbeams 14, mounting frames 15, and positioning components. The columns 12 are vertically arranged, and the crossbeams 14 are horizontally arranged. The top of the column 12 is provided with a hinged support, and the crossbeams 14 are rotatably connected to the hinged support. The mounting frames 15 are fixedly installed on the crossbeams 14, and photovoltaic panels 16 are installed on the mounting frames 15. One end of the telescopic push rod mechanism 13 is hinged to the column 12, and the other end of the telescopic push rod mechanism 13 is hinged to the mounting frames 15. The telescopic push rod mechanism 13 pushes the mounting frames 15 to swing back and forth around the central axis of the hinged support. The mounting frames 15 have slots 17 on the front and rear sides. The positioning components have blocks 18 corresponding to the slots 17. The blocks 18 are inserted into the slots 17. The positioning components are used to limit the front and rear sides of the photovoltaic panels 16.

[0038] In this embodiment, a positioning component is provided to limit the position of the photovoltaic panel 16, which facilitates the installation of the photovoltaic panel 16. This is because the mounting frame 15 can swing back and forth, making it difficult to keep the mounting frame 15 horizontal. When installing the photovoltaic panel 16, the photovoltaic panel 16 is prone to sliding along the upper surface of the mounting frame 15. On the one hand, the photovoltaic panel 16 is at risk of falling and being damaged. On the other hand, the mounting holes on the photovoltaic panel 16 are difficult to align with the threaded holes on the mounting frame 15, making it difficult to fix the photovoltaic panel 16 to the mounting frame 15 with screws. In this embodiment, the locking block 18 of the positioning component is inserted into the slot 17. The positioning component is used to limit the front and rear sides of the photovoltaic panel 16, so the photovoltaic panel 16 will not slide forward or backward. This can prevent the photovoltaic panel 16 from falling and facilitate subsequent fixing with screws.
