[0002] The column base structure is the part of a photovoltaic system that is directly connected to the installation foundation such as the ground or roof. It is often used for column installation, thereby supporting the entire photovoltaic array.
[0003] In related technologies, column base structures typically only support the installation of columns with a single cross-sectional size, but they are difficult to support the installation of columns with different cross-sectional specifications, resulting in poor adaptability of column base structures. Utility Model Content
[0004] The problem addressed in this disclosure is: how to improve the adaptability of column base structures.
[0005] To address the aforementioned issues, this disclosure provides a column base structure and a photovoltaic system.
[0006] In a first aspect, this disclosure provides a column base structure, including:
[0007] A base plate, wherein a sliding groove is provided on the base plate;
[0008] A first upright plate, the bottom end of which is provided with a first guide block, the first guide block being engaged in the sliding groove and slidably disposed relative to the sliding groove;
[0009] The second upright plate is fixed to the base plate, or the bottom end of the second upright plate is provided with a second guide block, which is engaged in the slide groove and slidably disposed relative to the slide groove.
[0010] Optionally, the cross-sectional shape of the chute is an inverted T-shape, and both the first guide block and the second guide block are adapted to the shape of the chute.
[0011] Optionally, an elastic element is provided between the first guide block and the end wall of the slide groove; and / or, an elastic element is provided between the second guide block and the end wall of the slide groove.
[0012] Optionally, the first upright plate and / or the second upright plate are provided with a first fastening hole.
[0013] Optionally, the base plate is provided with an installation port, a connecting plate is snapped into the installation port, and the connecting plate is provided with a first connecting hole.
[0014] Optionally, the mounting port is connected to the slide groove;
[0015] The connecting plate has a shoulder on its periphery, which passes through the connection between the mounting port and the slide groove and extends into the slide groove.
[0016] Optionally, the groove wall of the chute forms a limiting surface, and the limiting surface is disposed facing the bottom end of the base plate;
[0017] The shoulder abuts against the limiting surface.
[0018] Optionally, an anchor is fixed to the base plate for anchoring to the mounting surface.
[0019] Secondly, this disclosure provides a photovoltaic system, including a column and a column base structure as described above, wherein the column is installed in the column base structure.
[0020] Optionally, the column includes:
[0021] The main body is connected to the first and second upright plates of the column base structure;
[0022] A partition is fixed in the inner cavity of the body and is connected to the connecting plate of the column base structure.
[0023] Optionally, the inner wall of the body is provided with a locking protrusion;
[0024] The partition plate has a slot on its periphery, and the slot engages with the protrusion.
[0025] By engaging the first guide block in the slide groove and allowing it to slide relative to the slide groove, the first upright plate can be adjusted in position relative to the base plate. Furthermore, by fixing the second upright plate to the base plate or engaging the second guide block in the slide groove and allowing it to slide relative to the slide groove, the second upright plate can connect to different side walls of the column, respectively, and the second upright plate can also be adjusted in position relative to the base plate when it is movably engaged in the slide groove. In this way, at least one of the first and second upright plates can be adjusted in position relative to the base plate, which facilitates adjusting the position of the upright plate according to the column with different cross-sectional specifications to adapt to the different side walls of the column. This allows for adaptation to columns with different cross-sectional specifications, thereby improving the adaptability of the column base structure. At the same time, it ensures that there is no need to produce different specifications of column base structures according to different cross-sectional specifications of columns, making the materials more uniform and helping to reduce production costs.

[0045] In related technologies, column base structures often include a base plate and an upright plate, with the upright plate fixedly mounted on the base plate. Since the column needs to be connected to the upright plate when installed in the column base structure, the fixed mounting of the upright plate results in a fixed cross-sectional specification of the column that the column base structure can support. This makes it impossible to support the installation of columns with different cross-sectional specifications, thus leading to poor adaptability of the column base structure.
[0046] To address the technical problems existing in related technologies, this disclosure provides a column base structure and a photovoltaic system to improve the adaptability of the column base structure. A detailed description is provided below with reference to specific embodiments.
[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, a column base structure 10 provided in this embodiment includes a base plate 11, a first upright plate 122, and a second upright plate 123. A sliding groove 111 is provided on the base plate 11. A first guide block 124 is provided at the bottom end of the first upright plate 122. The first guide block 124 is engaged in the sliding groove 111 and slidably disposed relative to the sliding groove 111. The second upright plate 123 is fixed on the base plate 11. Alternatively, a second guide block 125 is provided at the bottom end of the second upright plate 123. The second guide block 125 is engaged in the sliding groove 111 and slidably disposed relative to the sliding groove 111.
[0048] It should be noted that the second upright plate 123 can be fixed to the base plate 11, or it can be movably engaged in the slide groove 111 via the second guide block 125, for example, referring to... Figure 1 The second upright plate 123 can be fixed to the base plate 11 by fixing bolts 1231, or for example, refer to Figure 2 The second upright plate 123 and the first upright plate 122 are respectively movably engaged in corresponding sliding grooves 111. The number of sliding grooves 111 is not limited and can be determined based on the number of upright plates 122 and 123 that need to be movably engaged. For example, if both the first upright plate 122 and the first upright plate 123 need to be movably engaged, two sliding grooves 111 can be provided in the base plate 11; if only the first upright plate 122 needs to be movably engaged, one sliding groove 111 can be provided in the base plate 11. Of course, the number of second upright plates 123 is also not limited; for example, referring to… Figure 3 Multiple second upright plates 123 can be provided, and multiple second upright plates 123 together with the first upright plate 122 form an insertion space for the insertion and installation of the upright.
[0049] In this embodiment, by engaging the first guide block 124 in the slide groove 111 and slidably oriented relative to the slide groove 111, the first upright plate 122 can be adjusted in position relative to the base plate 11. Furthermore, by fixing the second upright plate 123 to the base plate 11 or engaging the second guide block 125 in the slide groove 111 and slidably oriented relative to the slide groove 111, the second upright plate 123 can be connected to different side walls of the column 20 (see reference 122). Figure 5Furthermore, when the second upright plate 123 is movably engaged in the sliding groove 111, its position relative to the base plate 11 can also be adjusted. In this way, at least one of the first upright plates 122 and the second upright plate 123 can be adjusted relative to the base plate 11. This facilitates the adjustment of the upright plate position according to the different cross-sectional specifications of the columns 20 to adapt to the different side walls of the connecting columns 20, thereby adapting to columns 20 with different cross-sectional specifications. This improves the adaptability of the column base structure. At the same time, it ensures that there is no need to produce different specifications of column base structures according to different cross-sectional specifications of columns 20, making the materials more uniform and helping to reduce production costs.
[0050] Optionally, such as Figure 4 , Figure 6 and Figure 7 As shown, the cross-sectional shape of the slide groove 111 is an inverted T-shape, and the first guide block 124 and the second guide block 125 are both adapted to the shape of the slide groove 111.
[0051] Of course, the cross-sectional shape of the groove 111 can also be dovetail-shaped, cross-shaped, etc.
[0052] In this optional embodiment, the inverted T-shaped groove 111 can restrict the first guide block 124 and the second guide block 125 from disengaging from the groove 111 in the vertical direction, preventing the upright plate from accidentally detaching from the base plate 11.
[0053] Optionally, such as Figure 8 As shown, an elastic element 13 is provided between the first guide block 124 and the groove end wall of the slide 111; and / or, an elastic element 13 is provided between the second guide block 125 and the groove end wall of the slide 111.
[0054] Specifically, the elastic element 13 can be a spring or a sheet, etc., without limitation. In addition, one end of the elastic element 13 can be fixedly connected to the end wall of the groove 111, and the other end can abut against the first guide block 124 or the second guide block 125 to ensure that the elastic element 13 will not detach from the groove 111 during the extension and retraction process.
[0055] In this optional embodiment, since an elastic element 13 is provided between the guide block and the groove end wall of the slide 111, the elastic element 13 has a tendency to drive the upright plate closer to the column 20. Therefore, when the column 20 is placed between the upright plates and not tightened, the elastic element 13 can drive the upright plate to abut against the column 20, for example in... Figure 5 In this process, the elastic element 13 can drive a first upright plate 122 and three second upright plates 123 to clamp the column 20 together, so that the column 20 is not easy to tilt. At this time, it is more convenient to insert fastening bolts 16 through the column 20 and the upright plate to fasten the two, thereby improving the installation efficiency.
[0056] Optionally, such as Figure 4 and Figure 9As shown, the first upright plate 122 and / or the second upright plate 123 are provided with a first fastening hole 121.
[0057] Specifically, the column 20 is provided with a second fastening hole 211, and the first fastening hole 121 can be connected to the second fastening hole 211 by fastening bolt 16 so that the upright plate and the column 20 are fixed relative to each other.
[0058] Optionally, such as Figure 4 , Figure 6 and Figure 9 As shown, the base plate 11 is provided with an installation port 112, and a connecting plate 14 is snapped into the installation port 112. The connecting plate 14 is provided with a first connecting hole 141.
[0059] Specifically, the column 20 is provided with a second connecting hole 221, and the first connecting hole 141 can be connected to the second connecting hole 221 by a pre-tightening bolt 15 so that the connecting plate 14 and the column 20 are relatively fixed.
[0060] In this optional embodiment, the column 20 can be fixed through the first connecting hole 141 of the connecting plate 14, thereby indirectly securing the column 20 to the base plate 11. This helps to ensure the reliable installation of the column 20 on the column base structure 10.
[0061] Optionally, such as Figure 10 and Figure 11 As shown, the mounting port 112 is connected to the slide groove 111; the connecting plate 14 is provided with a shoulder 142 on its periphery, the shoulder 142 passes through the connection between the mounting port 112 and the slide groove 111 and extends into the slide groove 111.
[0062] In this optional embodiment, the shoulder 142 is inserted into the groove 111, and the groove 111 can, in turn, limit the shoulder 142, thereby preventing the connecting plate 14 from rotating about the axis of the first connecting hole 141.
[0063] Optionally, such as Figure 7 and Figure 12 As shown, the groove wall of the slide 111 forms a limiting surface 1111, which is disposed facing the bottom end of the base plate 11; the shoulder 142 abuts against the limiting surface 1111.
[0064] In this optional embodiment, the shoulder 142 can be pressed against the limiting surface 1111 under the action of the pre-tightening bolt 15, thereby fastening the base plate 11, connecting plate 14, pre-tightening bolt 15 and column 20 together, improving the installation reliability of column 20 on base plate 11.
[0065] Optionally, such as Figure 3As shown, an anchor 17 is fixed on the base plate 11, and the anchor 17 is used to anchor to the mounting surface.
[0066] Specifically, the anchor 17 may include an expansion bolt and a threaded sleeve. The expansion bolt may be inserted into both the base plate 11 and the mounting surface, and the threaded sleeve is screwed onto the end of the expansion bolt that extends above the base plate 11 to fix the base plate 11 to the mounting surface. It should be noted that the mounting surface may be the ground, roof, etc.
[0067] In this optional embodiment, the anchor 17 can be anchored to the mounting surface, thereby securing the base plate 11 to the mounting surface.
[0068] like Figure 5 As shown in the figure, a photovoltaic system provided in this disclosure includes a column 20 and a column base structure 10 as described above, wherein the column 20 is installed in the column base structure 10.
[0069] In this embodiment, since the photovoltaic system includes the aforementioned column base structure 10, it possesses all the beneficial effects brought about by all embodiments of the aforementioned column base structure 10, which will not be described in detail here.
[0070] Optionally, such as Figure 13 As shown, the column 20 includes a body 21 and a partition 22; the body 21 is connected to the first upright plate 122 and the second upright plate 123 of the column base structure 10; the partition 22 is fixed in the inner cavity of the body 21 and is connected to the connecting plate 14 of the column base structure 10.
[0071] Specifically, the second connecting hole 221 can be provided on the partition 22, and the second fastening hole 211 can be provided on the side wall of the body 21.
[0072] In this optional embodiment, by setting the column 20 as a body 21 and a partition 22, and the partition 22 is located in the inner cavity of the body 21, the partition 22 can support the opposite side walls of the body 21, thereby improving the deformation resistance of the column 20.
[0073] Optionally, such as Figure 13 As shown, the inner wall of the body 21 is provided with a latching protrusion 212; the periphery of the partition 22 is provided with a latching groove 222, which engages with the latching protrusion 212.
[0074] Specifically, the two opposing inner wall surfaces of the main body 21 can each be provided with a latching protrusion 212, and the periphery of the partition 22 can be provided with two latching grooves 222, which are respectively engaged with the two latching protrusions 212. In addition, the distance between the inner wall surface adjacent to the inner wall surface of the main body 21 and the latching protrusion 212 can be greater than the width of the partition 22. In this way, when installing the partition 22, it can first enter the main body 21 through the lower opening until it reaches the space between the latching protrusion 212 and the adjacent inner wall surface, and then slide horizontally until the latching groove 222 engages with the latching protrusion 212, thus finally realizing the installation of the partition 22.
[0075] In this optional embodiment, the partition 22 can be fixed inside the body 21 by interlocking the slot 222 and the protrusion 212. The slot 222 and the protrusion 212 have simple structures, which facilitates the quick assembly of the partition 22 and the body 21, and can improve the assembly convenience of the column 20.
[0076] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this disclosure.
