When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] The utility model provides a column assembly.

[0033] In this utility model technical solution, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 The column assembly includes a column body 100 and a sleeve 200. The sleeve 200 includes a tube body 210 and a bottom plate 220. The tube body 210 has an insertion groove 211. The insertion groove 211 has an insertion port 211a facing upward. The bottom end of the column body 100 is inserted into the tube body 210 through the insertion port 211a. The tube body 210 also has a grouting hole 212, which is connected to the insertion groove 211. The bottom plate 220 is connected to the bottom end of the tube body 210 for connecting with the installation surface.

[0034] The column body 100 is used as a part of the photovoltaic support to support the photovoltaic module. The column body 100 can be a prism or a cylinder or a column with a cross section of other special shapes. The sleeve 200 includes a tube body 210, and the tube body 210 has an insertion groove 211, and the insertion groove 211 has an insertion port 211a facing upward. The column body 100 is inserted into the insertion groove 211 of the tube body 210 through the insertion port 211a of the tube body 210, so that the tube body 210 has a certain protective effect on the bottom end of the column body 100, reducing the risk of the column body 100 being exposed to the outside and easily corroded and rusted by rain or humid environment. Specifically, the cross-sectional shape of the insertion groove 211 can be the same as the cross-sectional shape of the column body 100, or it can be different, as long as it is ensured that the column body 100 can be inserted into the insertion groove 211, so that the tube body 210 can protect the foot of the column body 100. In addition, the outer shape of the tube body 210 can be the same as the outer shape of the column body 100, or it can be different from the outer shape of the column body 100. For example, when the column body 100 is a prism, the outer shape of the tube body 210 can also be a prism, or it can also be a cylinder, or it can be a sphere or a hemisphere. In addition, the tube body 210 also has a grouting hole 212, and the grouting hole 212 is connected to the insertion groove 211. After the column body 100 is inserted into the insertion groove 211, concrete can be further poured into the insertion groove 211 through the grouting hole 212, so that the concrete fills the gap between the groove wall of the insertion groove 211 and the outer wall of the column body 100, so that the column body 100 forms a relatively firm connection effect with the tube body 210 through the concrete. Specifically, the grouting hole 212 can be a circular hole, a semicircular hole, a rectangular hole or a hole of other shapes, as long as it can achieve the effect of being connected to the insertion groove 211. In addition, the grouting hole 212 can be arranged adjacent to the insertion opening 211a so that the two are directly connected to each other, or the grouting hole 212 can also be arranged not adjacent to the insertion opening 211a so that the grouting hole 212 can only be connected to the insertion opening 211a through the insertion groove 211. Alternatively, the size of the insertion opening 211a can be set to be larger than the outer size of the column body 100, so that the insertion opening 211a can not only be used for the column body 100 to be inserted into the insertion groove 211, but also can be used as the grouting hole 212.

[0035] In order to ensure that the column assembly can be stably installed on the required installation surface, the bottom end of the tube body 210 is also connected to a bottom plate 220, and the column assembly can be connected to the installation surface through the bottom plate 220, so as to achieve the effect of connecting the entire column assembly to the installation surface. Specifically, the installation surface can be a roof or a ground. When the bottom plate 220 is connected to the installation surface, it can be connected by rivets, bolts 300, or concrete pouring. During the specific construction, the bottom plate 220 can be first connected to the installation surface, thereby achieving the effect of connecting the sleeve 200 to the installation surface, so that the sleeve 200 has a relatively stable state; then the column body 100 is inserted into the insertion groove 211 of the tube body 210 through the insertion port 211a, and then concrete is poured between the groove wall of the insertion groove 211 and the column body 100 through the grouting hole 212, so as to achieve the effect of fixing the column body 100 to the sleeve 200, so as to ensure that the column body 100 can stand stably on the installation surface. In addition, by pouring concrete between the groove wall of the insertion groove 211 and the column body 100 through the grouting hole 212, the insertion groove 211 and the column body 100 are well sealed, thereby further reducing the risk of the outer surface of the column body 100 being corroded by rain or a humid environment and rusting. Specifically, a connecting port can be opened at one end of the insertion groove 211 away from the insertion port 211a, thereby reducing the weight of the cylinder body 210; the bottom plate 220 can at least partially block the connecting port, or it can not block the connecting port. When the bottom plate 220 blocks the connecting port, the column body 100 can abut against the part of the bottom plate 220 that blocks the connecting port, and a connecting structure 222a for connecting to the mounting surface can be provided on the bottom plate 220, and the connecting structure 222a can be provided at the position of the bottom plate 220 for blocking the connecting port. In addition, the bottom plate 220 may further include a portion connected to the outer edge of the tube body 210 and extending in a direction away from the tube body 210 , and the portion may also be provided with a connection structure 222 a for connecting to the mounting surface.

[0036] By providing an insertion groove 211 on the main body 210 of the sleeve 200, and the insertion groove 211 has an insertion opening 211a facing upward, it is convenient for the column body 100 to be inserted into the insertion groove 211 from the insertion opening 211a of the insertion groove 211. In addition, by inserting the column body 100 into the insertion groove 211, the main body 210 can protect the foot of the column body 100, thereby reducing the risk of the column body 100 being corroded and rusted by rain or humid environment, thereby improving the service life of the column assembly. In addition, by also providing a grouting hole 212 on the main body 210, concrete can be poured into the insertion groove 211 through the grouting hole 212, so that the column body 100 can be connected to the main body 210 through the concrete, so as to achieve the effect of a stable connection between the column body 100 and the sleeve 200. By connecting the bottom plate 220 to the bottom end of the tube body 210 , the column assembly can be stably connected to the installation surface through the bottom plate 220 .

[0037] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The grouting hole 212 is formed by a depression in the inner wall of the insertion port 211 a and passes through the end surface of the tube body 210 away from the bottom plate 220 .

[0038] The grouting hole 212 is formed by a depression in the inner wall of the insertion port 211a, and the grouting hole 212 passes through the end surface of the tube body 210 away from the bottom plate 220, so that the grouting hole 212 is directly connected to the insertion port 211a, and it is also beneficial for the column body 100 to be inserted into the insertion groove 211 more smoothly.

[0039] Further, please refer to Figure 1 and Figure 5 At least two grouting holes 212 are provided, and the at least two grouting holes 212 are distributed at intervals along the circumference of the insertion port 211 a.

[0040] By providing at least two grouting holes 212, and at least two grouting holes 212 are distributed at intervals along the circumference of the insertion port 211a, concrete can be poured into the insertion groove 211 through the at least two grouting holes 212, thereby increasing the bonding area between the tube body 210 and the column body 100, thereby increasing the connection strength between the tube body 210 and the column body 100.

[0041] Specifically, when the column body 100 is a prism, each side edge of the column body 100 can be arranged corresponding to a grouting hole 212, so that when concrete is poured into the insertion groove 211 through these grouting holes 212, it is beneficial for the concrete to fill the gap between the groove wall of the insertion groove 211 and the column body 100, thereby further improving the connection strength between the column body 100 and the tube body 210.

[0042] Further, please refer to Figure 3 and Figure 6 The bottom plate 220 includes a relative portion 221 opposite to the insertion opening 211 a , and the relative portion 221 is connected to an end of the insertion groove 211 away from the insertion opening 211 a and abuts against the column body 100 .

[0043] By making the bottom plate 220 include the above-mentioned relative portion 221 , the column body 100 can abut against the relative portion 221 after being inserted into the insertion groove 211 without causing a risk of causing a large degree of damage to the installation surface.

[0044] Based on the solution that the bottom plate 220 includes the relative portion 221, further, please refer to Figure 3 and Figure 6 A limiting member 230 is disposed on one side of the relative portion 221 facing the insertion opening 211 a , and the limiting member 230 abuts against the side wall of the column body 100 to limit the circumferential position of the column body 100 .

[0045] By providing a limiter 230 on the side of the relative portion 221 facing the insertion opening 211 a and abutting against the side wall of the column body 100 , the column body 100 can be limited in the circumferential direction, thereby reducing the risk of the column body 100 tilting after being inserted into the insertion groove 211 .

[0046] Specifically, the limiting member 230 may be a plate-shaped limiting plate, a column-shaped limiting column, or a block-shaped limiting block, etc., and at least two limiting members 230 may be provided, so as to limit the opposite sides of the column body 100. More preferably, at least three limiting members 230 may be provided, and at least three limiting members 230 may be arranged at intervals along the circumference of the column body 100 to limit the entire circumference of the column body 100. Alternatively, the limiting member 230 may be a closed annular structure, and the annular structure is adapted to the shape of the column body 100. For example, when the column body 100 is a rectangular parallelepiped, the limiting member 230 may be a rectangular annular structure. When the column body 100 is a cylinder, the limiting member 230 may be a circular annular structure.

[0047] Based on the solution that the bottom plate 220 includes the relative portion 221, further, please refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 7 The bottom plate 220 further includes an extension portion 222 , which is connected to an edge of the opposite portion 221 , and the extension portion 222 is provided with a connection structure 222 a for connecting to the mounting surface.

[0048] By providing the above-mentioned extension part 222, and the extension part 222 is provided with a connection structure 222a connected to the installation surface, sufficient installation space can be provided for the user to connect the bottom plate 220 and the installation surface to each other. Specifically, the connection structure 222a can be a connection hole, or a connection column, etc. In one example, the extension part 222 is provided with at least two connection holes, and the connection holes are penetrated by bolts 300 or rivets to connect to the installation surface.

[0049] It is understandable that, in other embodiments, when the bottom plate 220 only has the relative portion 221 , the connecting structure 222 a may also be disposed on the relative portion 221 .

[0050] In one embodiment, please refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 7 A convex ring 223 is provided on one side of the bottom plate 220 facing the mounting surface. The connecting structure 222a is provided in the area enclosed by the convex ring 223. The convex ring 223 is used to abut against the mounting surface.

[0051] It is understandable that the conventional bottom plate 220 is usually in surface contact with the mounting surface, which results in poor sealing between the bottom plate 220 and the mounting surface. When the mounting surface is a roof, rainwater easily flows from the edge of the bottom plate 220 into the lower part of the bottom plate 220, and then flows into the roof through the connection structure 222a (for example, when the connection structure 222a is a connection hole), thereby causing leakage of the roof. In this example, after the bottom plate 220 is connected to the mounting surface, the bottom plate 220 can be pressed against the mounting surface. At this time, the bottom plate 220 abuts against the mounting surface through the convex ring 223 arranged toward the mounting surface, so that the contact form between the bottom plate 220 and the mounting surface is a line contact form, thereby improving the sealing between the bottom plate 220 and the mounting surface and reducing the risk of rainwater infiltrating into the house through the gap between the bottom plate 220 and the mounting surface. In addition, by arranging the connection structure 222a in the area enclosed by the convex ring 223, the convex ring 223 blocks rainwater, thereby reducing the risk of rainwater flowing into the roof through the connection structure 222a, and achieving a better waterproof effect. Specifically, the convex ring 223 can be formed by convexly convexly arranged from the side of the bottom plate 220 toward the installation surface. Alternatively, the convex ring 223 can also be a separate structure from the bottom plate 220, and the convex ring 223 is connected to the side of the bottom plate 220 facing the installation surface by bonding, welding or other connecting parts.

[0052] Furthermore, the protruding ring 223 may be disposed at an edge of the bottom plate 220 on a side facing the mounting surface, thereby further reducing the risk of rainwater entering the gap between the bottom plate 220 and the mounting surface.

[0053] Further, please refer to Figure 3 , Figure 4 , Figure 6as well as Figure 7 A reinforcing rib 224 is further provided on the side of the bottom plate 220 facing the mounting surface. The reinforcing rib 224 is located in the area enclosed by the convex ring 223 , and the two ends of the reinforcing rib 224 are respectively connected to the inner walls of the two opposite sides of the convex ring 223 .

[0054] By providing a reinforcing rib 224 on the side of the bottom plate 220 facing the installation, the reinforcing rib 224 is located in the area enclosed by the convex ring 223, and the two ends of the reinforcing rib 224 are respectively connected to the inner walls on the opposite sides of the convex ring 223. The convex ring 223 is made more stable through the reinforcing rib 224, thereby reducing the risk of the convex ring 223 being easily deformed. In addition, such a configuration also enhances the strength of the entire bottom plate 220.

[0055] Furthermore, a side of the reinforcing rib 224 facing the mounting surface is flush with a side of the convex ring 223 facing the mounting surface so as to abut against the mounting surface.

[0056] By arranging the side of the reinforcing rib 224 facing the mounting surface flush with the side of the convex ring 223 facing the mounting surface, the reinforcing rib 224 in this example can also abut the mounting surface under the premise that the convex ring 223 can abut against the mounting surface. As a result, after the convex ring 223 loses its waterproof effect, the reinforcing rib can further stop rainwater, thereby improving the waterproof level.

[0057] Further, please refer to Figure 4 and Figure 7 At least two reinforcing ribs 224 are provided, and at least two reinforcing ribs 224 are cross-arranged.

[0058] By providing two cross-arranged reinforcing ribs 224 , the two reinforcing ribs 224 can reinforce each other's strength, and the strength of the bottom plate 220 and the convex ring 223 are further strengthened.

[0059] Specifically, when the convex ring 223 is in a rectangular ring shape, the two reinforcing ribs 224 may be respectively disposed along two diagonal lines of the convex ring 223 , or the two reinforcing ribs 224 may respectively extend along two adjacent sides of the rectangular ring 223 .

[0060] Furthermore, the reinforcing ribs 224 divide the area enclosed by the protruding ring 223 into at least two sub-areas, and at least one connecting structure 222a is provided in each sub-area.

[0061] With such arrangement, on the one hand, the reinforcing strength of the reinforcing ribs 224 on the convex ring 223 and even the entire base plate 220 can be improved; on the other hand, when the seal at one of the connection structures 222a fails, the reinforcing ribs 224 can be used to seal other connection structures 222a, based on the premise that the reinforcing ribs 224 can abut against the installation surface, thereby reducing the risk of rainwater flowing to the roof and causing rainwater to penetrate the roof.

[0062] The present invention also proposes a photovoltaic bracket, which includes a column assembly. The specific structure of the column assembly refers to the above-mentioned embodiment. Since the photovoltaic bracket adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0063] The photovoltaic bracket is a structure used to support the photovoltaic module. The photovoltaic bracket may also include structures such as beams and purlins. The beams may be connected to the top of the column body 100 of the column assembly, and the purlins are connected to the beams and arranged at an angle to the beams, so that the photovoltaic module can be installed on the support structure formed by the interconnection of the beams and the purlins, thereby achieving a stable support effect for the photovoltaic module.

[0064] The present invention also proposes a photovoltaic system, which includes a photovoltaic bracket. The specific structure of the photovoltaic bracket refers to the above-mentioned embodiment. Since the photovoltaic system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0065] The photovoltaic system may also include photovoltaic modules, which are an important component of the photovoltaic system. The photovoltaic modules are installed on photovoltaic brackets to achieve a stable installation effect of the photovoltaic modules, thereby ensuring a stable working state of the photovoltaic system.
