Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component installation, in particular to a double-column bracket for installing photovoltaic components. Background Art

[0002] See also Figure 1 The current dual-column structure for photovoltaic module installation consists of a front column 1, a rear column 2, a diagonal beam 3, a front diagonal brace 4, and a rear diagonal brace 5. The diagonal beam 3 is mounted on top of the front and rear columns 1 and 2 via a U-shaped joint. The front diagonal brace 4 is bolted to the diagonal beam 3 at one end and connected to the front column 1 at the other end via a clamp. The rear diagonal brace 5 is bolted to the diagonal beam 3 at one end and connected to the rear column 2 at the other end via a clamp. Purlins 6 are mounted on the diagonal beam 3, and photovoltaic modules 7 are mounted on the purlins 6. The existing dual-column structure for photovoltaic module installation makes it difficult to adjust the tilt angle of the diagonal beam 3 after installation.

[0003] In response to this problem, Chinese patent document CN221227427U, published (announcement) date: 2024.06.25, discloses a double-column photovoltaic bracket and photovoltaic support system, wherein the double-column photovoltaic bracket includes: an inclined beam; two retractable columns, both vertically arranged on the ground; the top ends of the two retractable columns are respectively rotatably connected to the two ends of an inclined beam to support the inclined beam; two retractable diagonal braces, one end of each of which is rotatably connected to the inclined beam, and the other end is respectively rotatably connected to the bottom of the two retractable columns. Its feature is that by setting two retractable columns that can be telescopically adjusted and two retractable diagonal braces, the diagonal beam on the double-column photovoltaic bracket can be adjusted, thereby adjusting the inclination of the photovoltaic component; its disadvantage is that when the column in the bracket is telescopically adjusted, its threaded sleeve 102 is against the bolt 104, that is, the force of the entire column is all on this bolt 104, and since the column of the photovoltaic bracket is made of round tubes, the stability of the installation of the bolt 104 itself is poor, thereby reducing the structural stability of the entire double-column photovoltaic bracket.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] Example 1:

[0028] See Figure 2-5 A dual-column bracket for mounting photovoltaic modules includes a front column 1, a rear column 2, a diagonal beam 3, a front diagonal brace 4, and a rear diagonal brace 5. The diagonal beam 3 is mounted on the tops of the front column 1 and the rear column 2. One end of the front diagonal brace 4 is connected to the diagonal beam 3, and the other end is connected to the front column 1 via a clamp. The rear diagonal brace 5 is connected to the diagonal beam 3 at one end, and the other end is connected to the rear column 2 via a clamp. The diagonal beam 3 is used to mount purlins 6, and the purlins 6 are used to mount photovoltaic modules 7. An adjustment member is mounted on the front column 1 or the rear column 2, or on both the front column 1 and the rear column 2. By rotating the adjustment member, the height of the front column 1 and / or the rear column 2 can be adjusted.

[0029] In this embodiment, see Figure 3The adjusting member includes a screw rod 8 and a first adjusting nut 81. One end of the screw rod 8 is fixedly connected to the front column 1 or the rear column 2, and the other end is inserted into the front column 1 or the rear column 2. The first adjusting nut 81 is screwed and installed on the screw rod 8. One end of the screw rod 8 inserted into the front column 1 or the rear column 2 is provided with an axial long hole 83, and a limit bolt 84 passes through the front column 1 or the rear column 2 and the long hole 83. After loosening the limit bolt 84, the height of the front column 1 or the rear column 2 can be adjusted by rotating the first adjusting nut 81. The weight above the column is borne on the limit bolt 84, and the structural stability is better. After the adjustment is completed, the limit bolt 84 is tightened. Since the screw rod 8 has threads on the outside, after tightening the limit bolt 84, the column will deform and tightly press against the screw rod 8, which increases the friction between the column and the screw 8, further improving the structural stability.

[0030] Furthermore, a first limiting screw 82 is screwed onto the first adjusting nut 81. After the first limiting screw 82 is tightened, the first limiting screw 82 abuts against the screw rod 8, thereby preventing the first adjusting nut 81 from rotating.

[0031] Example 2:

[0032] In this embodiment, see Figure 4 The adjusting member includes a double-ended screw rod 9 with positive and negative threads, and the upper and lower ends of the double-ended screw rod 9 are respectively threadedly connected to the front column 1 or the rear column 2 on the upper and lower sides. By rotating the double-ended screw rod 9, the height of the column can be conveniently adjusted. Specifically, the double-ended screw rod 9 has a solid rod structure with high structural strength and good structural stability. The two ends of the double-ended screw rod 9 are respectively processed with positive external threads and negative external threads, and the upper and lower ends of the front column 1 or the rear column 2 are also respectively processed with positive internal threads and negative internal threads.

[0033] Furthermore, corresponding second adjustment nuts 91 are screwed onto the two ends of the double-ended screw rod 9. By tightening the second adjustment nuts 91, the double-ended screw rod 9 and the front column 1 or the rear column 2 are prevented from shaking, and at the same time, the upper end of the front column 1 or the rear column 2 is stressed on the second adjustment nuts 91, thereby improving the stability of the structure.

[0034] Furthermore, a second limiting screw 92 is screwed onto the second adjusting nut 91 . After the second limiting screw 92 is tightened, the second limiting screw 92 abuts against the double-headed screw 9 with positive and negative threads, thereby preventing the second adjusting nut 91 from rotating.

[0035] Example 3:

[0036] In this embodiment, see Figure 5The adjusting member includes a nut sleeve 10, the ends of which are threadedly connected to the upper and lower front columns 1 or rear columns 2, respectively. The nut sleeve 10 has positive and negative threads. By rotating the nut sleeve 10, the height of the front column 1 or rear column 2 can be adjusted.

[0037] Of course, nuts can also be screwed onto the front column 1 or the rear column 2 located at the upper and lower ends of the nut sleeve 10 to abut against the nut sleeve 10 .

[0038] Furthermore, one end or both ends of the nut sleeve 10 are screwed with a third limiting screw 11. After tightening the third limiting screw 11, the third limiting screw 11 abuts against the front column 1 or the rear column 2, thereby preventing the nut sleeve 10 from rotating.

[0039] The working principle or action process of the utility model is as follows:

[0040] See also Figure 2 To adjust the tilt angle of the diagonal beam 3, first loosen the clamps connecting the front diagonal brace 4 to the front column 1 and the rear diagonal brace 5 to the rear column 2. The clamps can now slide on the columns. By rotating the adjustment member, the height of the front column 1 and / or the rear column 2 can be adjusted, thereby adjusting the tilt angle of the diagonal beam 3. After the adjustment is complete, tighten the clamps. This type of adjustment is generally fine-tuning, with an optimal adjustment range of approximately 30 mm. It is mainly used in mountainous or sloping areas with complex on-site installation conditions.
