Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, specifically to a vertical photovoltaic bracket. Background Technology

[0002] With continuous innovation in photovoltaic power generation technology, ground-mounted photovoltaic power station support systems are gradually developing towards higher efficiency and greater efficiency. Vertical support systems, by arranging photovoltaic modules vertically at 90°, not only improve power generation efficiency in the morning and evening but also avoid the severe snow accumulation problems in some areas during winter. Currently, vertical photovoltaic support systems are showing broad application potential in agricultural ecology, road fencing, complex mountainous terrain, and high-latitude snowy regions.

[0003] When installing photovoltaic modules on a photovoltaic support column, the installation (locking bolts) is complex because the photovoltaic modules are placed vertically, and often requires high installation precision, which undoubtedly increases the difficulty of fixing bolts or other fasteners. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a vertical photovoltaic bracket that can greatly reduce the installation difficulty and improve the installation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vertical photovoltaic (PV) bracket includes columns, crossbeams, and locking components. At least two crossbeams are positioned between each pair of adjacent columns, forming mounting grooves for placing PV modules between adjacent crossbeams in the vertical direction. Each crossbeam has at least two locking components. Each locking component includes a pressure plate, a locking screw, and a locking block. The threaded end of the locking screw passes through the pressure plate and is threadedly connected to the locking block. The crossbeam has a through-hole for the locking block to pass through, a limiting hole that engages with the locking block, and an anti-rotation groove that engages with the locking block to prevent rotation. The through-hole and the limiting hole are interconnected, and both are located at the bottom of the anti-rotation groove. When the locking block is placed in the anti-rotation groove and the locking screw is tightened with the anti-rotation component, the pressure plate engages with the mounting groove to press the PV modules firmly.

[0006] After the above setup, before installing the photovoltaic modules, the locking assembly can be pre-connected, ensuring that the threaded end of the locking screw passes through the pressure plate and connects with the threaded block (without tightening). Then, the photovoltaic module is placed into the mounting slot, allowing the block to pass through the through hole and move to the limit hole position. At this point, rotating the locking screw causes the block to engage with the anti-rotation groove, allowing the locking screw to tighten. This ensures that the pressure plate and mounting slot work together to secure the photovoltaic module, achieving a stable installation of the photovoltaic module on the bracket. This operation eliminates the need for two people to be positioned at the front and back of the bracket to tighten the bolts, allowing for single-person operation. The process is simple and convenient, improving the efficiency and ease of photovoltaic installation.

[0007] The locking block is arched, and when placed in the anti-rotation groove, the arched top of the locking block faces the opening of the anti-rotation groove. When the locking screw is tightened, the arched locking block can rotate to a certain extent, thereby preventing loosening.

[0008] The locking block has a first edge, a second edge, a third edge, and a fourth edge. The first edge and the second edge are parallel to each other, and the third edge and the fourth edge are also parallel to each other. The third edge is located on one side of the first edge, and the fourth edge is located on the other side of the first edge. The included angle between the first edge and the third edge is an obtuse angle or an acute angle. The distance between the first edge and the second edge matches the width of the anti-rotation groove, and the length of the first edge is less than the width of the anti-rotation groove. The distance between the third edge and the fourth edge matches the width of the through hole. The inclined locking block can effectively achieve anti-rotation engagement with the anti-rotation groove, facilitating the tightening of the locking screw.

[0009] The crossbeam has a symmetrical structure, comprising a first connecting portion, two second connecting portions, and two third connecting portions. One third connecting portion, one second connecting portion, the first connecting portion, another second connecting portion, and another third connecting portion are sequentially connected. The two third connecting portions are on the same plane and parallel to the first connecting portion. The two second connecting portions are parallel to each other, and the first connecting portion is perpendicular to or at an angle to the second connecting portions. A through hole and a limiting hole are provided on the first connecting portion, and the first connecting portion and the two second connecting portions cooperate to form the anti-rotation groove. In vertically adjacent crossbeams, the second connecting portions and third connecting portions on adjacent sides of the two crossbeams cooperate to form the mounting groove. This type of crossbeam can cooperate with the crossbeams above and below to construct mounting grooves, simplifying the structure, and is also easy to process and shape.

[0010] The pressure plate is bent at its middle position to form a first slot, and the crossbeam is partially inserted into the first slot and abuts against the slot wall. With this configuration, the pressure plate will not rotate after the locking screws are tightened, thus ensuring reliable clamping of the photovoltaic module. In addition, when installing the locking assembly, the insertion of the pressure plate and the crossbeam facilitates one-handed operation.

[0011] The vertical photovoltaic support also includes connectors for connecting the columns and beams. These connectors are bolted or welded to both the columns and beams. The connectors ensure a secure connection between the columns and beams.

[0012] The connector includes a column connector and a crossbeam connector. The crossbeam connector connects to one side of the column connector, forming an L-shaped structure. The column connector, column, crossbeam connector, and crossbeam are all provided with connection holes for bolt engagement. This design makes the connector simple and easy to manufacture.

[0013] The connecting holes on both the column connection and the crossbeam connection are elongated oval holes. Several connecting holes are provided on the column, and these holes are spaced apart along the length of the column. The elongated oval holes better accommodate installation errors. Multiple connecting holes in the vertical direction of the column facilitate adjustment of the crossbeam height, thus adapting well to varying terrain and different specifications of photovoltaic modules, improving the versatility of the support system.

[0014] The connector includes a column connecting part and two crossbeam connecting parts. The two crossbeam connecting parts are respectively connected to both sides of the column connecting part. The middle position of the column connecting part is bent to form a second slot. The column is partially inserted into the second slot and abuts against the slot wall. The column connecting part, the column, the crossbeam connecting part, and the crossbeams are all provided with connecting holes for bolt engagement. This type of connector can be used to connect the crossbeams on both sides of the column, which helps to simplify the support structure. Furthermore, the second slot ensures that the connector will not rotate after being locked, which helps to maintain the structural stability of the support.

[0015] The connecting holes on the crossbeam connectors are all oblong holes; the column has several connecting holes, which are spaced apart along the length of the column. The oblong holes allow for better tolerance to bracket installation errors.

[0016] With the above solution, the bracket structure of this utility model is simple, which allows for vertical installation of photovoltaic modules. Moreover, it reduces the installation difficulty and makes the operation convenient, thereby improving the efficiency of photovoltaic installation. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0020] Example 1 like Figure 1-2 As shown, this utility model discloses a vertical photovoltaic support, which includes columns 10, crossbeams 20, and locking components 30. The number of columns 10 is adjusted according to the actual installation, but at least two columns 10 are provided. At least two crossbeams 20 are provided between each pair of adjacent columns 10, and these crossbeams 20 are spaced apart in the vertical direction. A mounting groove 25 for placing photovoltaic modules 50 is formed between each pair of adjacent crossbeams 20 in the vertical direction.

[0021] like Figure 3 and Figure 4As shown, in this embodiment, the column 10 and the crossbeam 20 are connected by a connector 40. The connector 40 has a column connecting part 41 and a crossbeam connecting part 42, which are connected to form an L-shaped structure. The connector 40 is bolted to the column 10 through the column connecting part 41 and to the crossbeam 20 through the crossbeam connecting part 42. The column connecting part 41, the column 10, the crossbeam connecting part 42, and the crossbeam 20 are all provided with connecting holes for bolting. The connecting holes on the column connecting part 41 and the crossbeam connecting part 42 are elongated holes 43, which can well accommodate the installation errors of the column 10. In addition, in order to facilitate the adjustment of the installation height of the crossbeam 20, the column 10 is provided with several connecting holes 11 spaced along its length. By passing bolts through the elongated holes 43 on the connector 40 and the connecting holes 11 on the column 10 and tightening them, the connector 40 and the column 10 are connected. Of course, as an alternative, connector 40 can be directly welded to crossbeam 20.

[0022] like Figure 5-13 As shown, the crossbeam 20 is a symmetrical, one-piece structure with a Z-shaped cross-section. It includes a first connecting portion 21, two second connecting portions 22, and two third connecting portions 23. One third connecting portion 23, one second connecting portion 22, the first connecting portion 21, another second connecting portion 22, and another third connecting portion 23 are connected sequentially. The two third connecting portions 23 are on the same plane and parallel to the first connecting portion 21, while the two second connecting portions 22 are parallel to each other. The first connecting portion 21 and the second connecting portions 22 are perpendicular to each other or at an angle, preferably the former. The first connecting portion 21 and the two second connecting portions 22 cooperate to form an anti-rotation groove 24. In the vertical direction, the second connecting portions 22 and third connecting portions 23 on adjacent sides of the crossbeams 20 cooperate to form the mounting groove 25.

[0023] Each crossbeam 20 is equipped with at least two locking components 30. Generally, a set of photovoltaic modules 50 corresponds to four sets of locking components 30 to ensure the stable installation of the photovoltaic modules 50. Each locking component 30 includes a pressure plate 31, a locking screw 32, and a locking block 33. The threaded end of the locking screw 32 passes through the pressure plate 31 and is threadedly connected to the locking block 33. The first connecting part 21 of the crossbeam 20 is provided with through holes 26 and limiting holes 27, each corresponding to a locking component 30. That is, the through holes 26 and limiting holes 27 are located at the bottom of the anti-rotation groove 24. The through holes 26 and limiting holes 27 are interconnected. It is preferable that the limiting holes 27 have a certain length, and it is preferable that the width W1 of the limiting holes 27 matches the diameter of the locking screw 32. The width W2 of the through holes 26 is greater than the width W1 of the limiting holes 27. The locking block 33 can pass through the through holes 26.

[0024] When the threaded end of the locking screw 32 passes through the pressure plate 31 and is threadedly connected to the locking block 33 (not tightened), the locking block 33 passes through the through hole 26 and is placed in the anti-rotation groove 24. Then, the locking block 33 moves towards the limiting hole 27, at which point the locking block 33 is in a stop-locking engagement with the limiting hole 27. Then, rotating the locking screw 32 causes the locking block 33 to rotate a certain angle, after which the locking block 33 is in an anti-rotation engagement with the anti-rotation groove 24. Continuing to rotate the locking screw 32 allows the threaded end of the locking screw 32 to be screwed into the locking block 33 until it is tightened. At this point, the pressure plate 31 presses tightly against the crossbeam 20. The pressure plate 31 partially extends into the crossbeam 20 and engages with the mounting groove 25 to press the photovoltaic module 50. The photovoltaic module 50 will not detach from the mounting groove 25 due to the obstruction of the pressure plate 31. It should be noted that the width of the mounting groove 25 should be compatible with the width of the photovoltaic module 50. The connection between the locking assembly 30 and the crossbeam 20 is simple and convenient to operate, and has high installation efficiency.

[0025] To prevent loosening, the locking block 33 is arched, and when placed in the anti-rotation groove 24, the arch apex 34 of the locking block 33 faces the opening of the anti-rotation groove 24. Furthermore, to ensure a reliable anti-rotation engagement between the locking block 33 and the anti-rotation groove 24, the shape of the locking block 33 is designed. Specifically, the locking block 33 has a first edge 35, a second edge 36, a third edge 37, and a fourth edge 38. The first edge 35 and the second edge 36 are parallel to each other, and the third edge 37 and the fourth edge 38 are parallel to each other. The third edge 37 is located on one side of the first edge 35, and the fourth edge 38 is located on the other side of the first edge 35. Similarly, the third edge 37 is also located on one side of the second edge 36, and the fourth edge 38 is located on the other side of the second edge 36. The angle between the first edge 35 and the third edge 37 is an obtuse or acute angle; that is, the first edge 35 and the third edge 37 are not perpendicular. The distance L1 between the first edge 35 and the second edge 36 is adapted to the groove width W3 of the anti-rotation groove 24, and the length L2 of the first edge 35 is less than the groove width W3 of the anti-rotation groove 24. The distance L3 between the third edge 37 and the fourth edge 38 is adapted to the width W2 of the through hole 26. The inclined locking block 33 can effectively achieve anti-rotation engagement with the anti-rotation groove 24, which is conducive to tightening the locking screw 32.

[0026] To prevent the pressure plate 31 from rotating and to ensure that the photovoltaic module 50 is reliably pressed, and to facilitate one-handed operation, the middle position of the pressure plate 31 is bent to form a first slot 39. A portion of the crossbeam 20 (all of the first connecting part 21 and part of the second connecting part 22) is inserted into the first slot 39 and abuts against the groove wall of the first slot 39.

[0027] Example 2 like Figure 14 and Figure 15As shown, the difference between this embodiment and Embodiment 1 lies in the adjustment of the structure of the connector 40. Specifically, the connector 40 in this embodiment has a column connecting part 41 and two crossbeam connecting parts 42. The column connecting part 41 is bent in the middle to form a second slot 44. The two crossbeam connecting parts 42 are respectively connected to both sides of the column connecting part 41, forming a U-shaped structure. The column connecting part 41, the column 10, the crossbeam connecting parts 42, and the crossbeam 20 are all provided with connecting holes for bolt engagement. The connecting holes on the two crossbeam connecting parts 42 are oblong holes 43. When the connector 40 is connected to the column 10, a portion of the column 10 is inserted into the second slot 44 and abuts against the groove wall of the second slot 44. In this way, the connector 40 will not rotate after being locked, which helps to maintain the structural stability of the bracket. The two crossbeam connecting parts 42 are respectively located on both sides of the column 10, so the connector 40 can be used to connect the crossbeams 20 on both sides of the column 10 at the same time, which helps to simplify the bracket structure.

[0028] In addition, the shape of the column 10 can be adapted to fit the connector 40 described in this embodiment.

[0029] In summary, the bracket structure of this utility model is simple, enabling the photovoltaic module 50 to be installed vertically. Moreover, it reduces the installation difficulty and is easy to operate, thereby improving the efficiency of photovoltaic installation.

Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
