Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to a photovoltaic support column base structure. Background Technology

[0002] A solar photovoltaic (PV) bracket is a special support structure designed for placing, installing, and fixing solar panels in a solar PV power generation system. The base of the bracket is fixed to the ground, and the base is used to determine the installation height of the bracket.

[0003] Common photovoltaic (PV) column bases typically consist of a support column and a base. The support column is usually welded to the base using welding. The high temperature of welding causes material deformation and residual stress, which may lead to cracks or embrittlement. Furthermore, the quality of the weld is greatly affected by the welder's skill, resulting in unstable structural strength of the column base after welding. Utility Model Content

[0004] To make the column base structure more stable, this application provides a photovoltaic support column base structure.

[0005] This application provides a photovoltaic support column base structure, which adopts the following technical solution:

[0006] A photovoltaic support column base structure includes a support column, the bottom of which is integrally formed with a base. The base has several through holes circumferentially formed for fixing bolts to pass through. The support column is a hollow structure, and a connecting hole is formed on one side of the support column. The connecting hole horizontally penetrates the opposite side of the support column and allows connecting bolts to pass through. When the support is located inside the support column, the connecting bolt passes through the connecting hole and exits from the other side of the support column, thus fixing the support inside the support column.

[0007] By adopting the above technical solution, the column base is fixed to the ground by fixing bolts passing through the through holes, which has good stability. When installing the bracket, the bracket is located inside the support column, and the connecting bolts pass through the connecting holes to make the bracket firmly fixed inside the support column. The support column and the base are integrally formed and molded in one piece, making the column base structure more stable and less prone to cracking or embrittlement.

[0008] Optionally, the inner wall at the connection between the support column and the base protrudes outward to form a convex arc surface.

[0009] By adopting the above technical solution, the convex arc surface improves the structural strength of the column base.

[0010] Optionally, there are four convex arc surfaces, the support column is a cuboid structure, the convex arc surfaces correspond one-to-one with the four sides of the cuboid, and the convex arc surfaces are located in the middle of one side of the support column.

[0011] By adopting the above technical solution, the convex arc surface is located in the middle of one side of the support column, which further improves the structural strength of the column base and reduces stress concentration.

[0012] Optionally, the connecting holes are provided in two sets. One set of the connecting holes includes two horizontally arranged connecting holes opened on one side of the support column, and the two sets of the connecting holes are respectively opened at the top and bottom of the support column.

[0013] By adopting the above technical solution, two sets of connection holes are respectively opened at the top and bottom of the support column, which improves the stability of the photovoltaic bracket installation.

[0014] Optionally, two first locking holes are vertically formed on one side of the support column, and the first locking holes horizontally penetrate the opposite side of the support column. Two second locking holes are formed on the side of the support column adjacent to the first locking holes, and the second locking holes horizontally penetrate the opposite side of the support column. One of the second locking holes is located between the two first locking holes at a vertical height, and the other second locking hole is higher than the first locking hole with the highest vertical height.

[0015] By adopting the above technical solution, the two first locking holes improve the stability of the photovoltaic bracket when it is installed on the column base, and the two second locking holes further improve the stability of the photovoltaic bracket when it is installed on the column base. The first locking holes and the second locking holes are vertically intersecting, making the photovoltaic bracket installation more secure.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The support column and base are integrally molded in one piece, making the column base structure more stable and less prone to cracking or embrittlement;

[0018] 2. The convex arc surface located in the middle of the supporting column reduces stress concentration and improves the structural strength of the column base;

[0019] 3. The first and second locking holes make the photovoltaic bracket installation more secure. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] This application discloses a photovoltaic support column base structure. (Refer to...) Figure 1 , Figure 2 A photovoltaic support column structure includes a support column 1. A base 2 is integrally formed at the bottom of the support column 1. The base 2 has several through holes 3 circumferentially formed for fixing bolts (not shown in the figure) to pass through. The inner wall at the connection between the support column 1 and the base 2 protrudes outward to form a convex arc surface 5. The support column 1, base 2, and convex arc surfaces 5 are integrally formed. There are four convex arc surfaces 5. The support column 1 has a cuboid structure, and the convex arc surfaces 5 correspond one-to-one with the four sides of the cuboid. The convex arc surfaces 5 are located at the center of one side of the support column 1.

[0025] Reference Figure 1 The support column 1 is a hollow structure. A connecting hole 4 is provided on one side of the support column 1, horizontally penetrating the opposite side of the support column 1. The connecting hole 4 allows a connecting bolt (not shown in the figure) to pass through. There are two sets of connecting holes 4. One set includes two horizontally arranged connecting holes 4 on one side of the support column 1, with the two sets of connecting holes 4 located at the top and bottom of the support column 1, respectively. When the bracket is located inside the support column 1, the connecting bolt passes through the connecting hole 4 and exits from the other side of the support column 1, fixing the bracket inside the support column 1.

[0026] Reference Figure 1 Two first locking holes 6 are vertically formed on one side of the support column 1, and the first locking holes 6 horizontally penetrate the opposite side of the support column 1. Two second locking holes 7 are formed on the side of the support column 1 adjacent to the first locking holes 6, and the second locking holes 7 horizontally penetrate the opposite side of the support column 1. One second locking hole 7 is located vertically between the two first locking holes 6, and the other second locking hole 7 is higher than the first locking hole 6 with the highest vertical height. Both the first locking holes 6 and the second locking holes 7 are for locking bolts (not shown in the figure) to pass through, and the locking bolts securely fix the bracket to the support column 1.

[0027] The implementation principle of a photovoltaic support column base structure in this application embodiment is as follows: fixing bolts pass through the through holes 3 on the column base and are fixed to the ground. When installing the photovoltaic support, the support is placed inside the support column 1. Connecting bolts pass through the connecting holes 4 at the top and bottom of the support column 1 respectively to make the support firmly fixed inside the support column 1. Then, locking bolts pass through two first locking holes 6 and two second locking holes 7 to further fix the support inside the support column 1. The support is firmly fixed. The support column 1 and the base 2 are integrally formed. The one-time forming structure has high strength, and the column base structure has more stable strength and is not prone to cracking or embrittlement.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
