Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and specifically relates to a highly stable solar photovoltaic support. Background Technology

[0002] As an important component of solar power generation systems, the stability and reliability of solar photovoltaic (PV) brackets directly affect the power generation efficiency and safety of the entire system. With the continuous development of solar energy technology and the expansion of its application fields, the requirements for solar PV brackets are becoming increasingly stringent.

[0003] The current announcement of Chinese utility model patent CN219918825U discloses a solar panel with a sun-tracking system. The panel has an I-shaped mounting frame with a windproof mechanism on its surface. The windproof mechanism houses the sun-tracking mechanism. In use, the solar panel folds according to wind speed to change its wind-receiving area and increase its wind resistance. The sun-tracking mechanism then causes the solar panel to rotate with the sun, improving energy conversion efficiency. The windproof mechanism includes a first rotating groove, a second rotating groove, a U-shaped frame, a rotating block, a connecting rod, a pulley, a limiting groove, a limiting frame, and a power component. In use, the U-shaped frame rotates in the first rotating groove, and the rotating block rotates in the second rotating groove, thereby driving the connecting rod to rotate.

[0004] This patent uses bolts to fix the solar panel to the ground. However, the fixing effect of bolts decreases after long-term use, and the solar panel is prone to tilting in strong winds, affecting its stability. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable solar photovoltaic support bracket, which solves the problem that existing solar panels with a sun-tracking system are fixed to the ground with bolts. However, the fixing effect of bolts decreases after long-term use, and the bracket is prone to tilting in strong winds, affecting its stability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a highly stable solar photovoltaic support, including a foundation and a pre-embedded pit opened on the foundation, a stable connection mechanism is provided in the pre-embedded pit, a column is provided on the stable connection mechanism, the number of columns is two and they are symmetrically arranged, and a solar panel is provided on the upper surface of the column.

[0007] The stable connection mechanism includes a concrete short column, anchor bolts, a base plate, nuts, spring grooves, sliding grooves, springs, and limiting blocks. The concrete short column is fixedly connected to the pre-embedded pit and is made of corrosion-resistant material. The anchor bolts are cast into the concrete short column and are evenly distributed. The base plate is placed on the concrete short column, and the upper end of the anchor bolt penetrates through the base plate. The nuts are placed on the anchor bolts and located on both sides of the base plate. The spring grooves are formed on the side wall of the concrete short column and are symmetrically distributed. The sliding groove is formed at one end of the spring groove, and the spring is fixedly placed in the spring groove. The limiting block is slidably placed in the sliding groove and contacts the side wall of the pre-embedded pit. A layer of concrete is filled between the concrete short column and the pre-embedded pit.

[0008] By adopting the above technical solution, through the setting of a foundation, a pre-buried pit, a stabilizing connection mechanism, a column, and a solar panel, in use, the stabilizing connection mechanism is first fixed in the pre-buried pit in the foundation, and then the column is fixed to the stabilizing connection mechanism. The pre-buried pit is then filled with concrete, which improves the stability of the column. The stabilizing connection mechanism includes a concrete short column, anchor bolts, a base plate, and nuts. In use, the concrete short column is first fixed in the pre-buried pit. The concrete short column has anti-corrosion properties, which can improve the service life of the concrete short column. Then, the anchor bolts can improve the strength of the concrete short column and can be connected to the base plate through the nuts. After the base plate and the column are fixed to the concrete short column, the pre-buried pit is filled with concrete, which can improve the strength of the column fixation and thus improve the stability of the column.

[0009] Furthermore: a first fixing seat is fixedly connected to the column, and a second fixing seat is fixedly connected to the foundation. The second fixing seat is located between the two columns, and a connecting plate is fixedly connected between the first fixing seat and the second fixing seat. The connecting plate is inclined.

[0010] By adopting the above technical solution, and by setting a first fixing seat, a second fixing seat, and a connecting plate, in use, the first fixing seat is first fixed on the column, and the two first fixing seats are set correspondingly. Then, the second fixing seat is fixed on the foundation and located between the two columns. The first fixing seat and the second fixing seat are connected by the connecting plate, which can improve the connection between the two columns and thus improve the stability of the columns.

[0011] Furthermore: a mounting base is fixedly connected to the upper end of the column, and a connecting block is fixedly connected to the mounting base, the connecting block being fixedly connected to the solar panel.

[0012] By adopting the above technical solution, by setting up an mounting base and a connecting block, the mounting base is fixed to the upper surface of the column during use, and then connected to the solar panel through the connecting block, thereby fixing the solar panel to the upper end of the column.

[0013] Furthermore: a horizontal plate is fixedly connected to the column by bolts, a support column is fixedly connected to the horizontal plate, and the other end of the support column is fixedly connected to the solar panel.

[0014] By adopting the above technical solution, and by setting up horizontal plates and support columns, the horizontal plates are first fixed to the columns during use, and then the solar panels are supported by the support columns, which further improves the stability of the columns in fixing the solar panels.

[0015] Furthermore: a shear groove is provided at the upper end of the concrete short column, and a shear key is fixedly connected to the lower surface of the base plate, the shear key being located in the shear groove.

[0016] By adopting the above technical solution, when the base plate and the concrete short column are connected by the shear key and the shear groove, the shear key will be completely embedded in the shear groove. This not only increases the contact area at the connection, but also significantly improves the shear bearing capacity of the connection through the physical locking effect. When subjected to horizontal shear force, the interaction between the shear key and the shear groove will effectively disperse and resist these forces, thereby preventing shear failure at the connection.

[0017] Furthermore: a reinforcing plate is fixedly connected between the base plate and the column, and the number of reinforcing plates is several and evenly arranged, and the cross-section of the reinforcing plate is triangular.

[0018] By adopting the above technical solution and setting up a reinforcing plate, the connection strength between the base plate and the column can be improved during use, thereby improving the stability of the column.

[0019] Furthermore: the column is made of a rotating profile.

[0020] By adopting the above technical solution, the material of the column is set. The column adopts a rotating profile, whose cross-sectional shape is rotationally symmetrical around a central axis. This not only provides uniform mechanical properties, but also makes the column have similar load-bearing capacity and stability in all directions.

[0021] Furthermore, a 40-60mm gap is reserved between the base plate and the short concrete column.

[0022] By adopting the above technical solution, and by setting a gap between the base plate and the concrete short column, the concrete can enter between the base plate and the concrete short column during use, thereby making the connection between the base plate and the concrete short column stronger and improving the stability of the column.

[0023] In summary, this utility model has the following beneficial effects:

[0024] By setting up a stable connection mechanism, the concrete short column is first fixed in the pre-embedded pit during use. The concrete short column has anti-corrosion effect, which can improve the service life of the concrete short column. Then, the anchor bolt can improve the strength of the concrete short column and can be connected to the base plate through the nut. After the base plate and the column are fixed on the concrete short column, the pre-embedded pit is filled with concrete to form a concrete layer, which can improve the strength of the column fixation and thus improve the stability of the column.

[0025] By setting up a first fixing seat, a second fixing seat, and a connecting plate, in use, the first fixing seat is first fixed on the column, and the two first fixing seats are set correspondingly. Then, the second fixing seat is fixed on the foundation and located between the two columns. The first fixing seat and the second fixing seat are connected by the connecting plate, which can improve the connection between the two columns and thus improve the stability of the columns.

[0026] Based on the above improvements, the overall technical effect achieved by this device is that it can make the connection between the column and the foundation more solid through concrete pouring, and prevent the column from being corroded by pre-embedding corrosion-resistant short concrete columns in the pre-embedded pit.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] Please see Figures 1-6 The present invention provides a technical solution: a highly stable solar photovoltaic support, including a foundation 1 and a pre-embedded pit 2 opened on the foundation 1. A stable connection mechanism 3 is provided in the pre-embedded pit 2. A column 4 is provided on the stable connection mechanism 3. There are two columns 4 arranged symmetrically. A solar panel 5 is provided on the upper surface of the column 4.

[0037] The stabilizing connection mechanism 3 includes a concrete short column 301, anchor bolts 302, a base plate 303, a nut 304, a spring groove 305, a sliding groove 306, a spring 307, and a limiting block 308. The concrete short column 301 is fixedly connected to the pre-embedded pit 2 and is made of corrosion-resistant material. The anchor bolts 302 are cast into the concrete short column 301, and there are several anchor bolts 302 evenly distributed. The base plate 303 is set on the concrete short column 301, and the upper end of the anchor bolt 302 passes through it. The base plate 303 and nuts 304 are set on the anchor bolts 302 and located on both sides of the base plate 303. Spring grooves 305 are opened on the side wall of the concrete short column 301. There are several spring grooves 305 and they are symmetrically arranged. A sliding groove 306 is opened at one end of the spring groove 305. The spring 307 is fixedly set in the spring groove 305. The limiting block 308 is slidably set in the sliding groove 306. The limiting block 308 is in contact with the side wall of the pre-embedded pit 2. A concrete layer is filled between the concrete short column 301 and the pre-embedded pit 2.

[0038] By setting up a foundation 1, a pre-buried pit 2, a stabilizing connection mechanism 3, a column 4, and a solar panel 5, in use, the stabilizing connection mechanism 3 is first fixed in the pre-buried pit 2 in the foundation 1, and then the column 4 is fixed to the stabilizing connection mechanism 3. The pre-buried pit 2 is then filled to improve the stability of the column 4. The stabilizing connection mechanism 3 includes a concrete short column 301, anchor bolts 302, a base plate 303, a nut 304, a spring groove 305, a sliding groove 306, a spring 307, and a limiting block 308. In use, the concrete short column 301 is first fixed in the pre-buried pit 2. The concrete short column 301 has anti-corrosion properties, which can improve its service life. Then, the anchor bolts 302 can improve the strength of the concrete short column 301 and can be fixed by the nut. 304 is connected to the base plate 303. After the base plate 303 and the column 4 are fixed on the concrete short column 301, the pre-embedded pit 2 is filled with concrete, which can improve the strength of the column 4 and thus improve the stability of the column 4. When the concrete short column 301 is placed into the pre-embedded pit 2, the side wall of the pre-embedded pit 2 can squeeze the limiting block 308, which in turn squeezes the spring 307. The force of the spring 307 restoring its deformation acts in the opposite direction on the limiting block 308, which squeezes the side wall of the pre-embedded pit 2, thus fixing the concrete short column 301 in the pre-embedded pit 2. This makes it easier to install the column 4 on the concrete short column 301 later and avoids the concrete short column 301 from shifting during the installation of the column 4, which would increase the installation difficulty.

[0039] refer to Figure 3 A first fixing seat 6 is fixedly connected to the column 4, and a second fixing seat 7 is fixedly connected to the foundation 1. The second fixing seat 7 is located between the two columns 4. A connecting plate 8 is fixedly connected between the first fixing seat 6 and the second fixing seat 7. The connecting plate 8 is set at an angle. By setting the first fixing seat 6, the second fixing seat 7 and the connecting plate 8, in use, the first fixing seat 6 is first fixed to the column 4 and the two first fixing seats 6 are set correspondingly. Then the second fixing seat 7 is fixed to the foundation 1 and is located between the two columns 4. The first fixing seat 6 and the second fixing seat 7 are connected by the connecting plate 8, which can improve the connection between the two columns 4 and thus improve the stability of the columns 4.

[0040] refer to Figure 2 An mounting base 9 is fixedly connected to the upper end of the column 4. A connecting block 10 is fixedly connected to the mounting base 9. The connecting block 10 is fixedly connected to the solar panel 5. By setting the mounting base 9 and the connecting block 10, the mounting base 9 is fixed to the upper surface of the column 4 during use, and then the connecting block 10 is connected to the solar panel 5, thereby fixing the solar panel 5 to the upper end of the column 4.

[0041] refer to Figure 2A horizontal plate 11 is fixedly connected to the column 4 by bolts, and a support column 12 is fixedly connected to the horizontal plate 11. The other end of the support column 12 is fixedly connected to the solar panel 5. By setting the horizontal plate 11 and the support column 12, when in use, the horizontal plate 11 is first fixed to the column 4, and then the solar panel 5 is supported by the support column 12, which further improves the stability of the column 4 in fixing the solar panel 5.

[0042] refer to Figure 5 The upper end of the concrete short column 301 is provided with a shear groove 13, and the lower surface of the base plate 303 is fixedly connected with a shear key 14. The shear key 14 is located in the shear groove 13. By setting the shear groove 13 and the shear key 14, when the base plate 303 and the concrete short column 301 are connected by the shear key 14 and the shear groove 13, the shear key 14 will be completely embedded in the shear groove 13. This not only increases the contact area at the connection, but also significantly improves the shear bearing capacity of the connection through the physical locking effect. When subjected to horizontal shear force, the interaction between the shear key 14 and the shear groove 13 will effectively disperse and resist these forces, thereby preventing shear failure at the connection.

[0043] refer to Figure 4 A reinforcing plate 15 is fixedly connected between the base plate 303 and the column 4. The reinforcing plate 15 is a number of plates and is evenly distributed. The cross-section of the reinforcing plate 15 is triangular. By setting the reinforcing plate 15, the connection strength between the base plate 303 and the column 4 can be improved during use, thereby improving the stability of the column 4.

[0044] refer to Figure 2 The column 4 is made of a rotating profile. By setting the material of the column 4, the column 4 adopts a rotating profile, whose cross-sectional shape is rotationally symmetrical about a central axis. This not only provides uniform mechanical properties, but also makes the column 4 have similar load-bearing capacity and stability in all directions.

[0045] refer to Figure 5 A 40-60mm gap is reserved between the base plate 303 and the concrete short column 301. By setting the gap between the base plate 303 and the concrete short column 301, the concrete can enter between the base plate 303 and the concrete short column 301 during use, thereby making the connection between the base plate 303 and the concrete short column 301 more solid and improving the stability of the column 4.

[0046] Brief description of usage:

[0047] In use, the concrete short column 301 is first fixed in the pre-embedded pit 2. The concrete short column 301 has anti-corrosion properties, which can improve its service life. Then, the anchor bolt 302 can improve the strength of the concrete short column 301 and can be connected to the base plate 303 through the nut 304. After the base plate 303 and the column 4 are fixed to the concrete short column 301, the pre-embedded pit 2 is poured with concrete, which can improve the fixing strength of the column 4 and thus improve the stability of the column 4. When the base plate 303 and the concrete short column 301 are connected through the shear key 14 and the shear groove 13, the shear key 14 will be completely embedded in the shear groove 13, which not only increases the contact area at the connection, but also significantly improves the connection through the physical locking effect. The shear bearing capacity of the joint is such that when subjected to horizontal shear force, the interaction between the shear key 14 and the shear groove 13 effectively disperses and resists these forces, thereby preventing shear failure at the joint. Furthermore, when the concrete short column 301 is placed into the pre-embedded pit 2, the side wall of the pre-embedded pit 2 can compress the limiting block 308, which in turn compresses the spring 307. The force of the spring 307 restoring its deformation acts in the opposite direction on the limiting block 308, and the limiting block 308 compresses the side wall of the pre-embedded pit 2, thereby fixing the concrete short column 301 in the pre-embedded pit 2. This facilitates the subsequent installation of the column 4 on the concrete short column 301 and prevents the concrete short column 301 from shifting during the installation of the column 4, thus reducing the difficulty of installation.

[0048] Then, the first fixing seat 6 is fixed on the column 4, and two first fixing seats 6 are set correspondingly. Then, the second fixing seat 7 is fixed on the foundation 1 and located between the two columns 4. The first fixing seat 6 and the second fixing seat 7 are connected by the connecting plate 8, which can improve the connection between the two columns 4 and thus improve the stability of the columns 4.

[0049] Finally, the mounting base 9 is fixed to the upper surface of the column 4, and then connected to the solar panel 5 through the connecting block 10, thereby fixing the solar panel 5 to the upper end of the column 4. The horizontal plate 11 is fixed on the column 4, and then the solar panel 5 is supported by the support column 12, further improving the stability of the column 4 in fixing the solar panel 5.

[0050] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
