Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic bracket installation, and specifically provides a photovoltaic bracket installation fixture. Background Technology

[0002] A photovoltaic (PV) support system is a crucial component used to support PV modules. It comprises columns, diagonal beams, and purlins. The lower end of the column is fixed to the foundation, and the diagonal beams are fixed to the upper end of the column. Multiple diagonal beams are installed, inclined relative to the horizontal plane, with the angle of inclination related to the sunlight angle at the installation location. Multiple purlins are spaced along the length of the diagonal beams and fixed to them. PV modules are mounted on the purlins, and the spacing between adjacent purlins is related to the length of the PV module.

[0003] Before installing the purlins, lines need to be drawn on the inclined beam according to the spacing between adjacent purlins. The purlins are then installed according to these lines to determine their installation positions. This installation method is inefficient and inaccurate. During installation, because the purlins are unsupported and easily cover the lines, they are prone to shifting, leading to errors in the spacing between adjacent purlins. This ultimately makes the installation of photovoltaic modules difficult. This is especially true in harsh environments such as polar regions, where construction is extremely difficult and installation errors are further amplified.

[0004] Therefore, there is an urgent need for a photovoltaic bracket installation fixture to solve the problem of poor purlin installation accuracy during the installation of existing photovoltaic brackets. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0032] To address the problem of poor purlin installation accuracy during the installation of existing photovoltaic brackets, this utility model provides an installation fixture for photovoltaic brackets.

[0033] like Figure 1 and Figure 2 As shown, the photovoltaic support structure of this utility model includes a column 1, a diagonal beam 2, and purlins 3. The lower end of the column 1 is fixed to the foundation, and the diagonal beam 2 is fixed to the upper end of the column 1. Multiple diagonal beams 2 are provided, inclined relative to the horizontal plane, and their angle of inclination is related to the sunlight angle at the installation location. Multiple purlins 3 are located above the diagonal beam 2 and intersect with it. The purlins 3 are spaced apart along the length of the diagonal beam 2 and fixed to it.

[0034] The installation fixture of this utility model is configured to be positioned above and parallel to the inclined beam 2, and both ends of the installation fixture can respectively abut against two adjacent purlins 3 to limit the spacing between adjacent purlins 3. Specifically, during the installation of purlins 3, firstly, the first purlin 3 is fixed to the inclined beam 2. Then, the installation fixture is placed on at least two inclined beams 2, with the lower end of the installation fixture abutting against the first purlin 3. Next, the second purlin 3 is placed on the inclined beam 2, with the upper end of the second purlin 3 abutting against the installation fixture, thereby precisely limiting the spacing between the two purlins 3. Finally, the second purlin 3 is fixed to the inclined beam 2. This process is repeated until all purlins 3 are installed. This invention utilizes an installation fixture to position two adjacent purlins 3, which can quickly and accurately define the spacing between the two adjacent purlins 3, thereby improving the efficiency and accuracy of purlin installation. It can also improve the parallelism of the two adjacent purlins 3 and reduce the installation difficulty of photovoltaic modules.

[0035] like Figure 3 As shown, the installation fixture of this utility model includes at least two support rods 4 and a locking member 5. Adjacent support rods 4 are interlocked to achieve telescoping along the axis of the installation fixture. The locking member 5 is located at the interlocking point of adjacent support rods 4 and is used to lock the adjacent support rods 4. By controlling the locking member 5, the telescoping between adjacent support rods 4 in the installation fixture can be locked, thereby changing the length of the installation fixture to adapt to different installation conditions. Furthermore, after the second purlin 3 is positioned, the installation fixture can be removed by shortening its length, reducing the difficulty of disassembling the installation fixture.

[0036] In the illustrations of this utility model, the mounting fixture includes two support rods 4, each with a rectangular cross-section. It should be noted that the above examples are merely for illustrating the structure of the mounting fixture in this utility model and are not intended to limit its specific application. Without departing from the principle of this utility model, the support rods 4 can also be three or more, and their cross-sectional shapes can be circular, triangular, etc.

[0037] like Figure 3 As shown, in two adjacent support rods 4, the outer support rod 4 has a through hole 41, and the inner support rod 4 has a limiting hole 42. As the two support rods 4 extend and retract along the axial direction, the through hole 41 and the limiting hole 42 can align. (The last sentence appears to be incomplete and possibly refers to a technical detail.) Figure 4 As shown, the locking component 5 includes a locking rod 51, which can pass through the through hole 41 and the limiting hole 42 to lock the two support rods 4. Of course, as the locking rod 51 disengages from the limiting hole 42, the two adjacent support rods 4 can be released from their locked state and extend or retract in the axial direction.

[0038] In the examples of this utility model, such as Figure 4 and Figure 5 As shown, the locking component 5 also includes a locking cap 52, a spring 53, and a guide portion 54. The guide portion 54 is fixed to the outermost support rod 4 among two adjacent support rods 4. The locking cap 52 is fixed to the end of the locking rod 51 away from the support rod 4. The locking rod 51 is inserted into the guide portion 54. The spring 53 is sleeved on the outside of the locking rod 51. One end of the spring 53 is fixed to the locking cap 52, and the other end is fixed to the guide portion 54. After the operator pulls the locking cap 52 and the locking rod 51 outward, the locking rod 51 gradually disengages from the limiting hole 42. At this time, the two adjacent support rods 4 can move along the axial direction to extend and retract. At the same time, the spring 53 deforms and changes to a stretched state. After the operator removes the external force, the spring 53 in the stretched state can drive the locking cap 52 and the locking rod 51 to move towards the support rod 4, and then insert into the limiting hole 42 to lock the two adjacent support rods 4.

[0039] The guide portion 54 is provided with an annular groove for accommodating the spring 53. When the spring 53 is in its natural state (i.e., when the locking member 5 is in its locked state), the spring 53 is completely accommodated in the annular groove of the guide portion 54.

[0040] In some examples, such as Figure 3 As shown, multiple limiting holes 42 are provided along the axial direction of the support rod 4. After the through hole 41 is aligned with different limiting holes 42, the total length of two adjacent support rods 4 will also be different, that is, the total length of the mounting fixture will be different, so that the length of the mounting fixture can be adjusted to meet the needs of different positioning lengths.

[0041] like Figure 3 and Figure 6 As shown, the installation fixture is equipped with a limiting member 6, which is connected to the inclined beam 2. The limiting member 6 is configured to guide the installation fixture along the length direction of the inclined beam 2 and limit the installation fixture along the length direction of the purlin 3. During the installation process, the second purlin 3 will inevitably move along its length direction to adjust its position. The limiting member 6's positioning of the installation fixture along the length direction of the purlin 3 prevents the installation fixture from shifting during this adjustment process, thus avoiding affecting the installation. Furthermore, the limiting member 6's guidance along the length direction of the inclined beam 2 ensures that the installation fixture can be arranged along the length direction of the inclined beam 2 and facilitates position adjustment. For example, the limiting member 6 can be plate-shaped, with an individual limiting member 6 on each support rod 4.

[0042] Furthermore, the limiting component 6 allows for a certain distance between the support rod 4 and the inclined beam 2, creating an installation space for initial fixing of the second purlin 3 and the inclined beam 2 using bolts or similar materials. Moreover, in conjunction with... Figure 2As shown, the limiting member 6 closest to the second purlin 3 (i.e. the purlin located at the upper end of the mounting fixture) is a certain distance from the end of the mounting fixture, so as to prevent the limiting member 6 from reducing the working space for fixing the second purlin 3 and the inclined beam 2.

[0043] Regarding the cooperation structure between the limiting member 6 and the inclined beam 2, this utility model provides several examples for reference.

[0044] In the first example, such as Figure 6 As shown, the inclined beam 2 has a limiting groove 21 along its length, and a portion of the limiting member 6 is accommodated within the limiting groove 21, thereby guiding the installation fixture along the length of the inclined beam 2. Simultaneously, along the length of the purlin 3, the size of the portion of the limiting member 6 accommodated in the limiting groove 21 is equal to the size of the limiting groove 21, thereby limiting the installation fixture along the length of the purlin 3. For example, along the length of the purlin 3, there may be one or more limiting grooves 21, and the size of the portion of each limiting member 6 accommodated in the limiting groove 21 is equal to the size of the limiting groove 21. For example, the limiting groove 21 may be located on the top surface or both sides of the inclined beam 2. For example, the limiting member 6 may be fixed to the bottom surface 71 or both sides of at least one support rod 4.

[0045] In the second example, such as Figure 7 As shown, the inclined beam 2 has a limiting groove 21 along its length direction. A portion of the limiting member 6 is accommodated in the limiting groove 21, thereby guiding the installation fixture along the length direction of the inclined beam 2. At the same time, the limiting groove 21 corresponds one-to-one with the limiting member 6, and at least two are provided along the length direction of the purlin 3. The inclined beam 2 between two adjacent limiting grooves 21 forms a protrusion 22. Along the length direction of the purlin 3, the size of the protrusion 22 is equal to the size between two adjacent limiting members 6, so as to limit the installation fixture along the length direction of the purlin 3.

[0046] In the third example, such as Figure 8As shown, a limiting groove 21 is formed along the length of the inclined beam 2. A portion of the limiting member 6 is housed within the limiting groove 21, thereby guiding the installation fixture along the length of the inclined beam 2. Simultaneously, a wedge-shaped clamping member 7 is provided within the limiting groove 21. The end of the wedge-shaped clamping member 7 is housed within the limiting groove 21, causing the limiting member 6 to adhere tightly to the side wall of the limiting groove 21, thereby limiting the installation fixture along the length of the purlin 3. Specifically, the wedge-shaped clamping member 7 includes an opposing bottom surface 71 and a wedge-shaped surface 72. The bottom surface 71 adheres tightly to the limiting member 6, and the wedge-shaped surface 72 contacts the side wall of the limiting groove 21. As the end of the wedge-shaped clamping member 7 is gradually inserted into the limiting groove 21, the wedge-shaped clamping member 7 forces the limiting member 6 to gradually adhere tightly to the other side wall of the limiting groove 21, thereby limiting the installation fixture along the length of the purlin 3. In addition, if the orthographic projection of at least one limiting member 6 on the inclined beam 2 falls outside the orthographic projection range of the mounting fixture on the inclined beam 2, then the wedge-shaped clamping member 7 can be installed in the limiting groove 21 corresponding to the limiting member 6 located outside the mounting fixture, so as to facilitate striking the wedge-shaped clamping member 7.

[0047] In summary, the usage process of the installation fixture provided by this utility model is as follows:

[0048] First, fix the first purlin 3 to the inclined beam 2. Then, place installation fixtures of suitable and equal length on at least two inclined beams 2, with the lower end of the fixture abutting against the first purlin 3. Next, place the second purlin 3 on the inclined beam 2, with the upper end of the second purlin 3 abutting against the installation fixture, thus quickly and accurately defining the spacing between the two purlins 3. After fixing the second purlin 3 to the inclined beam 2, release the locking piece 5 from the support rod 4, retract the installation fixture, and remove it. Repeat this process until all purlins 3 are installed.

[0049] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
