Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and specifically refers to a column structure for a photovoltaic support. Background Technology

[0002] A photovoltaic (PV) support structure is an important structure used to support PV modules. It not only ensures the stability and safety of PV modules, but also effectively improves the power generation efficiency of PV systems.

[0003] In existing technologies, there are generally two methods for fixing photovoltaic (PV) brackets to the ground: the first is to fix them by pouring cement, which provides a stable structure but is cumbersome to construct, has a long construction period, is inconvenient to dismantle later, and is relatively expensive; the second is to fix them by ground piles, which is more commonly used in practice due to its convenient and quick construction and high flexibility. The bracket base (or "column base") is the connector between the ground piles and the column. The current installation process involves first driving the ground piles into the ground, and then assembling the bracket base, column, PV bracket, and PV modules in sequence from bottom to top. Since the ground piles are equivalent to the "foundation" of the entire PV bracket, their installation positions need to be pre-designed and fixed, resulting in the top of the column being already a certain distance above the ground after assembly. This means that installing the PV brackets and modules is already off-ground, requiring the use of tripods or other devices for elevation, which is inconvenient, especially when operators need to frequently move positions, leading to low installation efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a column structure for a photovoltaic support, which solves the problems existing in the prior art. The photovoltaic system can be assembled according to the conventional process, but the operation is simpler and more convenient.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A photovoltaic support column structure includes a ground pile, a support base, a column, a first bolt, a second bolt, and at least two third bolts; the support base includes a connecting plate at the bottom and two parallel connecting plates vertically connected to the upper surface of the connecting plate; the lower end of the column is inserted between the connecting plates; the first bolt and the second bolt both pass through the two connecting plates and the column; the third bolts pass through both connecting plates and are located on opposite sides of the column.

[0007] A flange is provided at the upper end of the ground pile; the connecting plate is connected and fixed to the flange by a number of fourth bolts, which are inserted into the connecting plate and the flange from top to bottom.

[0008] Preferably, the flange and the connecting plate are respectively provided with a plurality of flange holes and connecting holes for the fourth bolt to pass through; the flange holes are elongated holes extending radially along the flange and are arranged at equal angular intervals around the center of the flange; the connecting holes are arc holes concentric with the connecting plate and are arranged at equal angular intervals around the center of the connecting plate.

[0009] Preferably, a plurality of flange reinforcing ribs are provided between the upper circumferential surface of the ground pile and the lower surface of the flange.

[0010] The connecting plate is provided with a first mounting hole for the first bolt to pass through, a second mounting hole for the second bolt to pass through, and a third mounting hole for the third bolt to pass through; the lower end of the column is provided with a first through hole opposite to the first mounting hole and a second through hole opposite to the second mounting hole.

[0011] Preferably, the photovoltaic support column structure further includes at least two fifth bolts; the first bolt and the second bolt are arranged vertically; the fifth bolts are all inserted through the two connecting plates and the column, and are arranged in pairs on both sides of the first bolt.

Detailed Implementation

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] refer to Figures 1 to 3 As shown, this utility model discloses a column structure for a photovoltaic support, including a ground pile 1, a support base 2, a column 3, a first bolt 4, a second bolt 5, and at least two third bolts 6;

[0026] Ground pile 1 is usually driven into the ground by means of threaded connection;

[0027] The bracket base 2 includes a connecting plate 21 at the bottom and two parallel connecting plates 22 that are vertically connected to the upper surface of the connecting plate 21;

[0028] The lower end of the column 3 is inserted between the connecting plates 22 and locked by the first bolt 4 and the second bolt 5. The first bolt 4 and the second bolt 5 are both inserted through the two connecting plates 22 and the column 3.

[0029] The third bolt 6 is inserted into both connecting plates 22 and is located on opposite sides of the column 3.

[0030] refer to Figure 4 , 5 As shown, through the above scheme, when assembling the photovoltaic system, the present invention can follow the existing process to drive ground piles 1 into the ground (indicated by the dotted line in the figure), and then install the bracket base 2 and the column 3. When assembling the column 3, either the first bolt 4 or the second bolt 5 can be installed. At this time, the bracket base 2 can swing around the already installed first bolt 4 or second bolt 5 as an axis, so that the upper end of the column 3 is laid down on the ground or rested on a support a. First, the photovoltaic bracket b and photovoltaic module c are assembled on the upper end of the column 3. After assembly, the column 3 together with the photovoltaic bracket b and photovoltaic module c is lifted until the column 3 is in a vertical state. Finally, the second bolt 5 or the first bolt 4 and the third bolt 6 are locked in.

[0031] This invention eliminates the need to lock the column 3 to the support base 2 during assembly, allowing it to swing freely. Therefore, it eliminates the need to install the photovoltaic support b and photovoltaic module c off the ground, making operation more convenient and assembly more efficient. Simultaneously, the first bolt 4, the second bolt 5 passing through the column 3, and the third bolt 6 located on the side of the column 3 are used to lock and limit its movement, ensuring sufficient connection strength between the lower end of the column 3 and the support base 2, resulting in higher structural stability. Furthermore, the third bolt 6 on one side can be pre-locked during assembly for positioning the column 3 when it is lifted, ensuring that the column 3 can be quickly raised to a vertical position.

[0032] The following are specific embodiments of the present invention.

[0033] The upper end of the aforementioned pile 1 is provided with a flange 11; the connecting plate 21 is connected and fixed to the flange 11 by a number of fourth bolts 7, which are inserted from top to bottom through the connecting plate 21 and the flange 11.

[0034] Furthermore, the flange 11 and connecting plate 21 are respectively provided with a plurality of flange holes 111 and connecting holes 211 for the fourth bolt 7 to pass through. The flange holes 111 are elongated holes extending radially along the flange 11, and are arranged at equal angular intervals around the center of the flange 11. The connecting holes 211 are arc-shaped holes concentric with the connecting plate 21, and are arranged at equal angular intervals around the center of the connecting plate 21. As a result, there is a larger adjustment range when locking the flange 11 and the connecting plate 21, making the position adjustment of the support base 2 more flexible and convenient, and better able to adapt to the situation where the ground pile 1 deviates from the preset installation position, with a higher installation error tolerance. In addition, the arc shape of the connecting holes 211 makes the movement of the fourth bolt 7 in the connecting holes 211 smoother during adjustment, thereby reducing resistance, avoiding wear on the connecting holes 211, and improving service life.

[0035] Meanwhile, a number of flange reinforcing ribs 12 are provided between the upper circumferential surface of the aforementioned pile 1 and the lower surface of the flange 11 to improve the structural strength of the flange 11.

[0036] The connecting plate 22 is provided with a first mounting hole 221 for the first bolt 4 to pass through, a second mounting hole 222 for the second bolt 5 to pass through, and a third mounting hole 223 for the third bolt 6 to pass through; the lower end of the column 3 is provided with a first through hole 31 opposite to the first mounting hole 221 and a second through hole 32 opposite to the second mounting hole 222.

[0037] Furthermore, this utility model also includes at least two fifth bolts 8; the first bolt 4 and the second bolt 5 are arranged vertically; the fifth bolts 8 are all inserted through the two connecting plates 22 and the column 3, and are arranged in pairs on both sides of the first bolt 4 (they may not be at the same height as the first bolt 4), further improving the connection strength between the column 3 and the support base 2.

[0038] Secondly, the connecting plate 22 is provided with a fourth mounting hole 224 for the fifth bolt 8 to pass through, and the lower end of the column 3 is provided with a third through hole 33 opposite to the fourth mounting hole 224.

[0039] Furthermore, the first mounting hole 221, the second mounting hole 222, and the fourth mounting hole 224 are all elongated holes extending in the vertical direction, while the first through hole 31, the second through hole 32, and the third through hole 33 are all round holes. This allows for adjustment of the installation height of the column 3.

[0040] In this embodiment, two pairs of the third bolt 6 and the fifth bolt 8 are provided, resulting in higher connection strength.

[0041] A connecting plate reinforcing rib 23 is provided between the outer side of the connecting plate 22 and the upper surface of the connecting disk 21 to improve the structural strength of the connecting plate 22.

[0042] It should be noted that the bolts mentioned above are typically secured with nuts, washers, and shims to ensure that the bolt does not move axially after passing through the corresponding part. This is common knowledge, therefore the positional relationships of nuts, washers, and shims will not be elaborated upon when describing the corresponding connection relationships.

[0043] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
