[0034] In related technologies, photovoltaic power stations can use a counterweight block with a certain weight to connect with the support to form a photovoltaic bracket. The counterweight block is subjected to a greater gravity to play a more stable anchoring role on the support column, so that the photovoltaic bracket can stably support and fix the photovoltaic module, prevent the photovoltaic module from being overturned by the large wind load, and ensure the stable operation of the photovoltaic power station. However, the shape of the counterweight block is mostly complex and the overall weight is relatively large, which makes the processing and manufacturing process of the photovoltaic bracket more complicated and more difficult to transport and install, resulting in inconvenient construction of the photovoltaic bracket and low assembly efficiency. In response to the above problems, the present application proposes a photovoltaic bracket.

[0035] See also Figures 1 to 10 In one embodiment of the present specification, the photovoltaic bracket 1000 includes at least two support columns 200 and at least two column base structures 100, and at least two support columns 200 are arranged at intervals; one column base structure 100 is connected to one support column 200, and at least part of the structure of the column base structure 100 is used to be pre-embedded in the wall of a building.

[0036] In this embodiment, the photovoltaic power station can make the photovoltaic bracket 1000 include at least two support columns 200 and at least two column base structures 100. By connecting and installing a support column 200 on a column base structure 100, the support column 200 can be stably and reliably anchored under the coordinated fixing action of the column base structure 100 and the building wall. Two or more support columns 200 can be used to respectively connect and fix the opposite sides of a photovoltaic component 400; or multiple support columns 200 and column base structures 100 can be arranged in an array on the building wall, and multiple support columns 200 can be used to connect the four sides of the photovoltaic component 400 according to the weight of the photovoltaic component 400, so that the photovoltaic bracket 1000 can stably connect and support the photovoltaic component 400, thereby ensuring the stable and reliable operation of the photovoltaic power station. Among them, the photovoltaic bracket 1000 can use a pressure block to press the frame of the photovoltaic component 400 at the end of the support column 200, or can use fasteners such as bolts, pins, and self-tapping screws to connect and fix the photovoltaic component 400 to the end of the support column 200 to achieve stable installation of the photovoltaic component 400 and the support column 200.

[0037] The column base structure 100 can be a block structure with a certain volume size, or it can be a frame structure formed by splicing and combining multiple plates. The photovoltaic bracket 1000 can pre-embed the column base structure 100 in the building wall when the building wall is cast and constructed, so that the column base structure 100 can be stably set on the building wall when the building wall is solidified; or, a certain size of installation groove can be opened on the building wall, and the column base structure 100 can be placed in the installation groove and then filled with filling glue or concrete that is tightly connected to the wall material, so that the column base structure 100 is pre-embedded in the building wall. Furthermore, by pre-embedding at least part of the column base structure 100 in the wall of the building, the column base structure 100 and the building wall can form an integrated structure, effectively enhancing the tensile strength of the column base structure 100 on the building wall, which is beneficial for preventing the photovoltaic component 400 from overturning the photovoltaic bracket 1000 when subjected to external forces such as wind loads, so that the photovoltaic bracket 1000 can more stably and reliably support and fix the photovoltaic component 400, thereby improving the overall structural stability and reliability of the photovoltaic bracket 1000.

[0038] By embedding the column foot structure 100 of the photovoltaic bracket 1000 in the building wall to anchor the support column 200, there is no need to set a heavy counterweight to fix the support column 200, so that construction workers do not need to transfer and transport heavy counterweights during assembly, which can better reduce the workload of construction workers, achieve more convenient and reliable construction and assembly of the photovoltaic bracket 1000, and effectively improve the assembly convenience and efficiency of the photovoltaic bracket 1000. Compared with the method of directly installing the support column 200 on the wall using expansion screws, the use of the column foot structure 100 embedded in the wall can reduce damage to the building wall and reduce the risk of water seepage. At the same time, the pre-embedding of the column foot structure 100 in the wall can better improve the pull-out resistance of the photovoltaic bracket 1000, ensure the stable assembly of the photovoltaic bracket 1000, and improve the practicality and reliability of the photovoltaic bracket 1000.

[0039] In one embodiment of the present specification, by pre-embedding at least a portion of the column base structure 100 within the wall of a building, and connecting the column base structure 100 to the support column 200 on the wall of the building, the column base structure 100 can be connected to the building wall and form a whole with the building wall, effectively improving the pull-out resistance of the column base structure 100, so that the support column 200 can stably connect and support the photovoltaic module 400 when connected to the column base structure 100, effectively improving the load-bearing capacity of the photovoltaic bracket 1000, and ensuring that the photovoltaic bracket 1000 provides stable and reliable support for the photovoltaic module 400. By pre-embedding the column base structure 100, the photovoltaic bracket 1000 can be assembled by directly connecting the support column 200 during the construction process, effectively improving the assembly convenience and efficiency of the photovoltaic bracket 1000.

[0040] See Figure 3 、 Figure 4 and Figure 6 In one embodiment of the present specification, the column base structure 100 includes a mounting portion 10 and a fixing portion 30. The mounting portion 10 is provided with a connecting structure for connecting to the support column 200. At least a portion of the mounting portion 10 is pre-embedded in the wall of a building. The fixing portion 30 is connected to one side of the mounting portion 10 and is pre-embedded in the wall of the building.

[0041] In this embodiment, the column base structure 100 can have the fixing portion 30 be configured as a plate or block structure with a certain contact volume, so that when the fixing portion 30 is pre-embedded in the building wall, it can fully fit in contact with the building material, thereby improving the stable connection between the column base structure 100 and the building wall; alternatively, a certain number of holes can be opened on the fixing portion 30, and when the fixing portion 30 is pre-embedded, concrete or a filling connection colloid can be passed through the holes to solidify, so that the fixing portion 30 can be more firmly embedded in the building wall; or alternatively, a protruding structure can be provided on the outer periphery of the fixing portion 30, so that the protruding structure can provide a larger gripping area when the fixing portion 30 is embedded in the wall, thereby achieving a tight connection between the column base structure 100 and the building wall. Furthermore, by using the fixing portion 30 to be embedded in the building wall, the column base structure 100 can be effectively prevented from being pulled out of the building wall due to a large tensile force, thereby achieving stable support of the column base structure 100 to the support column 200.

[0042] At this time, when the column base structure 100 is installed in the wall, the connection structure on the mounting portion 10 can be exposed on the wall surface of the building. At least part of the structure of the mounting portion 10 and the fixing portion 30 can be used to cooperate with the building wall for embedded installation, thereby achieving stable support for the connection structure and ensuring the supporting effect of the column base structure 100. The connection structure can be a protruding bolt; or it can be a screw hole provided in the mounting portion 10, so that the entrance of the screw hole is exposed; or it can be a boss protruding on the wall surface, so that the support column 200 of the photovoltaic bracket 1000 can be connected and fixed to the connection structure and the support column 200 using a nut that cooperates with the bolt, or bolts can be provided on the bottom plate of the support column 200 to cooperate with the screw holes of the connection structure, or the bottom plate of the support column 200 and the boss of the connection structure can be welded to achieve stable installation and fixation of the support column 200 and the column base structure 100, thereby ensuring the structural stability and reliability of the photovoltaic bracket 1000.

[0043] Furthermore, by making the column base structure 100 embedded in the wall of the building using at least part of the structure of the mounting part 10 and the fixing part 30, the connection structure of the mounting part 10 is exposed on the wall of the building to connect the support column 200. This allows the column base structure 100 to be better combined with the building wall to form an overall structure, which is conducive to better supporting and fixing the support column 200, so that the photovoltaic bracket 1000 can stably and reliably support the installation of the photovoltaic module 400, thereby ensuring the stable operation of the photovoltaic power station.

[0044] See Figure 4 、 Figure 6 and Figure 9In one embodiment of the present invention, the mounting portion 10 includes a mounting panel 11 and a connecting post 13. The fixing portion 30 is connected to the mounting panel 11. The connecting post 13 is connected to the mounting panel 11 and is arranged side by side with the fixing portion 30. The connecting post 13 has a mounting hole 131 defined therein, and the mounting panel 11 has a relief opening corresponding to and communicating with the mounting hole 131. The relief opening and the mounting hole 131 form a connecting structure.

[0045] In this embodiment, the mounting portion 10 can expose one side of the mounting panel 11 on the wall of the building when the column base structure 100 is pre-buried and installed, so that the support column 200 can be more conveniently assembled in correspondence with the position of the column base structure 100. By providing a connecting column 13 on the other side of the mounting panel 11, the connecting column 13 can be arranged side by side with the fixing portion 30, so that when the column base structure 100 is pre-buried and installed in the building wall, the connecting column 13 and the fixing portion 30 can be embedded in the building wall, further increasing the contact area between the column base structure 100 and the building wall, and achieving a more stable and reliable installation and fixing effect of the column base structure 100. Among them, by setting a mounting hole 131 in the connecting column 13 and setting an avoidance opening connected to the mounting hole 131 on the mounting panel 11, an internal thread can be set in the mounting hole 131, and a bolt can be used to pass through the bottom plate 33 of the support column 200 and the avoidance opening to enter the mounting hole 131, and the bolt is threadedly connected with the connecting column 13, thereby realizing convenient assembly of the support column 200 and the column base structure 100, which is conducive to better improving the practicality and reliability of the photovoltaic bracket 1000.

[0046] Among them, the installation part 10 can be provided with at least two connecting columns 13 on one side of the installation panel 11, so that the column base structure 100 can further increase the connection and fixing effect with the building wall under the action of at least two connecting columns 13, and at the same time, at least two connecting columns 13 can be used to increase the connection area with the support column 200, which is conducive to better improving the pull-out resistance of the column base structure 100, and further improving the connection stability between the column base structure 100 and the support column 200, so that the photovoltaic bracket 1000 can more stably and reliably support and fix the photovoltaic component 400.

[0047] See Figure 8 In one embodiment of the present specification, the width of the connecting pillar 13 is configured to gradually increase along the first direction.

[0048] It can be understood that the first direction can be the depth direction of the column base structure 100 embedded in the wall. By setting the width of the connecting column 13 to gradually increase along the first direction, the connecting column 13 can be set in a structural form with a narrow upper part and a wide lower part in the first direction. In this way, when the column base structure 100 is embedded and installed in the building wall, the connecting column 13 and the wall structure can be installed in a coordinated and limited manner, thereby better improving the connection stability and reliability between the connecting column 13 and the building wall, which is conducive to better improving the pull-out resistance of the column base structure 100 after installation, preventing the column base structure 100 from detaching from the wall, and further improving the assembly stability and reliability of the photovoltaic bracket 1000.

[0049] See Figure 6 and Figure 7 In one embodiment of the present specification, the mounting portion 10 is further provided with a first waterproof structure 15 , and the first waterproof structure 15 is connected to the outer peripheral side of the mounting panel 11 in a surrounding manner.

[0050] In this embodiment, the first waterproof structure 15 is connected around the periphery of the mounting panel 11. The first waterproof structure 15 can be fixedly adhered to the outer peripheral side of the mounting panel 11 by waterproof adhesive, or a groove structure or a protrusion structure can be provided on the outer peripheral side of the mounting panel 11 to be fastened to the first waterproof structure 15. Alternatively, the mounting panel 11 and the first waterproof structure 15 can be formed using an integral molding process to ensure a tight fit between the mounting panel 11 and the first waterproof structure 15. In this case, the material of the first waterproof structure 15 can be set to a material that has a certain fit and connection performance with concrete, so that when the column base structure 100 is pre-buried in the building wall, the fit and connection between the first waterproof structure 15 and the building wall can be used to achieve a better waterproof effect, effectively preventing water falling on the building wall from seeping into the building wall through the gap between the column base structure 100 and the building wall, thereby effectively improving the practicality and reliability of the photovoltaic bracket 1000.

[0051] See Figure 5 and Figure 7 In one embodiment of the present specification, a limiting groove 111 is provided on the outer peripheral side of the mounting panel 11 , and the first waterproof structure 15 is snapped into the limiting groove 111 .

[0052] In this embodiment, the shape of the retaining groove 111 can correspond to the shape of the first waterproof structure 15, so that the first waterproof structure 15 can be snap-fitted into the retaining groove 111, thereby improving the stability and reliability of the connection between the first waterproof structure 15 and the installation panel 11, better preventing water leakage after the column base structure 100 is installed, and further improving the practicality and reliability of the column base structure 100. Specifically, snap-fitting protrusions can be provided on the opposing inner sidewalls of the retaining groove 111, which abut against the outer wall of the first waterproof structure 15, further improving the stability and reliability of the connection between the installation panel 11 and the first waterproof structure 15. Alternatively, two spaced-apart retaining top plates can be provided at the notch of the retaining groove 111, and the retaining groove 111 can be provided on the opposing outer sidewalls of the first waterproof structure 15. The snap-fitting engagement between the retaining top plates and the retaining groove 111 can ensure a secure installation of the first waterproof structure 15 on the installation panel 11, further improving the stability of the connection between the first waterproof structure 15 and the installation panel 11.

[0053] See Figure 10 In one embodiment of the present specification, the fixing portion 30 is a support block, and the width of the support block is configured to gradually increase along the first direction.

[0054] In this embodiment, the fixing portion 30 can be arranged in a support block structure with a certain volume. At this time, by gradually increasing the width of the support block along the first direction, that is, the fixing portion 30 is arranged to be narrow at the top and wide at the bottom along the embedding depth direction of the column base structure 100, after the column base structure 100 is installed on the wall, the fixing portion 30 and the wall of the building can achieve a certain limiting assembly effect, which is conducive to better preventing the column base structure 100 from being pulled out of the wall of the building with a certain probability when subjected to a large upward force, further improving the tensile strength of the column base structure 100 after installation, and ensuring the stable support of the photovoltaic bracket 1000 on the photovoltaic component 400.

[0055] See Figure 3 、 Figure 6 and Figure 8 In one embodiment of the present specification, the fixing portion 30 includes a connecting plate 31 and a bottom plate 33 . The bottom plate 33 is disposed opposite to the mounting portion 10 , and the connecting plate 31 connects the mounting portion 10 and the bottom plate 33 .

[0056] In this embodiment, the fixing portion 30 may include a connecting plate 31 and a base plate 33. By using the connecting plate 31 to connect the base plate 33 and the mounting portion 10, the front view of the column base structure 100 can be similar to an I-shaped structural setting. Furthermore, when the column base structure 100 is pre-embedded in the wall of the building, part of the wall structure can be solidified and formed between the mounting portion 10 and the base plate 33, and connected to the opposite sides of the connecting plate 31, so that the column base structure 100 can achieve a better limited installation effect with the wall of the building, effectively preventing the column base structure 100 from being pulled out of the building wall, improving the pull-out resistance of the column base structure 100 after installation, ensuring that the photovoltaic bracket 1000 has a more stable support effect on the photovoltaic component 400, and further improving the practicality and reliability of the photovoltaic bracket 1000.

[0057] Among them, such as Figure 8 As shown, the width of the connecting plate 31 can be set to gradually increase along the first direction. At this time, the connecting plate 31 can be set in a structural form with a narrow upper part and a wide lower part in the first direction. In this way, the limiting installation effect of the column base structure 100 and the building wall can be further improved, which is conducive to better preventing the column base structure 100 from being pulled out of the building wall, achieving a more reliable anchoring effect of the column base structure 100 on the support column 200, ensuring the stable support of the photovoltaic bracket 1000 to the photovoltaic component 400, and further improving the practicality and reliability of the column base structure 100.

[0058] See Figure 3 and Figure 6 In one embodiment of the present specification, the fixing portion 30 is provided with a second waterproof structure 35 , and the second waterproof structure 35 is arranged around the connection node between the connecting plate 31 and the bottom plate 33 .

[0059] In this embodiment, by arranging the second waterproof structure 35 around the connection node between the connecting plate 31 and the bottom plate 33, the second waterproof structure 35 can be fixedly adhered to the connection node by a waterproof adhesive, or a groove structure or a protrusion structure that is fastened to the second waterproof structure 35 can be provided on the connecting plate 31 and the bottom plate 33, or the connecting plate 31, the bottom plate 33 and the second waterproof structure 35 can be formed by an integral molding process to ensure a tight fit connection between the fixing portion 30 and the second waterproof structure 35. Under the action of the second waterproof structure 35, the second waterproof structure 35 can be better utilized to fill the gap between the fixing part 30 and the building wall, thereby achieving a better waterproof effect and ensuring the stable and reliable assembly of the column base structure 100 on the building wall; at the same time, the second waterproof structure 35 can be utilized to isolate moisture from acting on the connection node between the connecting plate 31 and the bottom plate 33, thereby better preventing the fixing part 30 from being corroded by water vapor and having a certain probability of causing the connecting plate 31 and the bottom plate 33 to break, thereby further improving the structural stability and reliability of the column base structure 100 and ensuring the stable and reliable installation of the photovoltaic bracket 1000 on the building wall.

[0060] See Figure 1 、 Figure 2 、 Figure 3 and Figure 9 In one embodiment of the present specification, the fixing portion 30 of the column base structure 100 is provided with a serial hole 311, and the photovoltaic bracket 1000 further includes a serial rib 300, which is passed through the serial hole 311 and is pre-embedded in the wall of the building.

[0061] In this embodiment, by passing the series ribs 300 through the series holes 311 of the fixing part 30, and then pre-embedded and installed together with the fixing part 30 in the wall of the building, the series ribs 300 can be used to further increase the connection area between the column base structure 100 and the building wall, thereby realizing the limiting assembly function of the column base structure 100 and the building wall, which is conducive to better preventing the column base structure 100 from being pulled out of the building wall and improving the installation stability and reliability of the column base structure 100 in the building wall. Among them, when the photovoltaic bracket 1000 is provided with multiple column base structures 100 connecting multiple support columns 200, the series ribs 300 can be set with ribs of larger length, which is conducive to using the series ribs 300 to pass through the series holes 311 of multiple column base structures 100, and making the multiple column base structures 100 install the support columns 200 at intervals required. The overall structural stability and reliability of the photovoltaic bracket 1000 can be further improved under the series fixing action of the series ribs 300, which is conducive to using the series ribs 300 to transfer the tension of some column base structures 100 to other column base structures 100, ensuring the overall force balance of the photovoltaic bracket 1000, so that the photovoltaic bracket 1000 can more stably support and fix multiple photovoltaic modules 400, further improving the practicality and reliability of the photovoltaic bracket 1000.

[0062] In one embodiment of the present specification, the support column 200 and the column base structure 100 are detachably connected; or, the support column 200 and the column base structure 100 are integrally formed.

[0063] It can be understood that one end of the support column 200 can be provided with a chassis that is installed in conjunction with the column base structure 100. At this time, the chassis of the support column 200 and the mounting portion 10 of the column base structure 100 can be connected by fastening bolts, expansion screws or pins; or a clip structure can be used to clamp the chassis of the fixed support column 200 and the mounting portion 10 of the column base structure 100, so that the support column 200 and the column base structure 100 can adopt a detachable connection combination structure setting, which is conducive to more convenient connection and fixation of the support column 200 and the column base structure 100 during the construction process, thereby realizing quick assembly of the photovoltaic module 400. At the same time, only the support column 200 can be removed from the building wall for maintenance and replacement, reducing damage to the building wall during inspection and maintenance of the photovoltaic bracket 1000, and further improving the practicality and reliability of the photovoltaic bracket 1000.
