[0062] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0063] The principle of the photovoltaic bracket 10 proposed in this application is described in detail below:

[0064] In the related art, the installation process of the photovoltaic bracket is to tension the component cables and install the photovoltaic components on the component cables after the side columns and the center column are installed. The installation of the photovoltaic components is a high-altitude operation with low installation efficiency, high cost and great risk.

[0065] In order to solve this technical problem, the present application provides a photovoltaic bracket 10, which is referred to below. Figures 1-12 A photovoltaic bracket 10 according to an embodiment of the present application is described.

[0066] like Figure 1 As shown, the photovoltaic support 10 of the embodiment of the present application includes: a side support structure 100, a middle support structure 200, a component cable 300 and a diagonal cable 400.

[0067] like Figure 3 and Figure 4 As shown, the edge support structure 100 includes edge columns 110 and adjustment column feet 120 .

[0068] The side columns 110 may be made of aluminum alloy, stainless steel, hot-dip galvanized steel, or composite materials, and are not specifically limited in this embodiment.

[0069] The cross section of the side column 110 may be circular, rectangular, triangular or polygonal, and the shape may be customized according to specific installation needs and design requirements.

[0070] The adjusting column foot 120 is hinged to the bottom of the side column 110 along the first direction z1.

[0071] In this embodiment, the adjustment column foot 120 can be hinged to the bottom of the side column 110 along the first direction z1 through a pin shaft. The hinge between the adjustment column foot 120 and the bottom of the side column 110 can be subjected to rust-proof treatment such as coating, or metal materials that are not easy to rust, such as stainless steel, aluminum or copper, can be selected.

[0072] The side pillar 110 has a first posture and a second posture.

[0073] The angle between the side column 110 and the horizontal plane when the side column 110 is in the first posture is smaller than the angle between the side column 110 and the horizontal plane when the side column 110 is in the second posture.

[0074] like Figure 2 and Figure 6 As shown, in this embodiment, when the side column 110 is in the first posture, the top of the side column 110 is close to the construction ground, and the angle between the side column 110 and the horizontal plane is a first angle α1. When the side column 110 is in the second posture, the side column 110 is in a vertical state or has a certain inclination angle with the vertical direction. At this time, the angle between the side column 110 and the horizontal plane is a second angle α2, and the component cable 300 is in a tensioned state.

[0075] like Figure 7 As shown, the central support structure 200 includes a central pillar 210 and a central beam 220 .

[0076] The center column 210 can be made of aluminum alloy, stainless steel, hot-dip galvanized steel or composite materials. The material of the center column 210 can be the same as or different from that of the side columns 110.

[0077] In some embodiments, the installation height requirement of the photovoltaic assembly 20 is relatively high, and the center column 210 can be designed as a multi-section center column 210 structure. The multi-section center columns 210 are arranged layer by layer, and the multi-section center columns 210 can move relative to each other to adjust the height of the center column 210. After adjusting to the designed height, they are limited and tightened.

[0078] In this embodiment, the center column 210 is fixed to the pipe pile by welding.

[0079] The center beam 220 is mounted on the top of the center pillar 210 .

[0080] The center beam 220 can be installed on the center pillar 210 by bolt connection or welding.

[0081] In this embodiment, after the center beam 220 is installed on the top of the center column 210, the length direction of the center beam 220 forms a certain angle with the horizontal plane, so that the photovoltaic module 20 can better receive light.

[0082] For example, the center beam 220 is provided with a mounting hole, in which a wire rope clamp is installed for mounting the component rope 300 .

[0083] like Figure 1 As shown, the component cable 300 extends along a first direction z1.

[0084] In this embodiment, the first direction z1 is the length direction of the component cable 300 .

[0085] The component cable 300 is used to connect between the side columns 110 at both ends of the photovoltaic support 10 , and the component cable 300 is connected to the center beam 220 .

[0086] The stay cables 400 are used to fix the side columns 110 to the construction ground when the side columns 110 are in the second posture.

[0087] In this embodiment, when the side column 110 is in the second posture, the stay cable 400 fixes the side column 110 to the construction ground through the stay cable pile foundation.

[0088] like Figure 2 As shown, the side column 110 is used to install the component cable 300 and the photovoltaic component 20 when it is in the first posture.

[0089] In this embodiment, when the side column 110 is in the first posture, the top of the side column 110 is close to the construction ground, so that the component cable 300 and the photovoltaic component 20 can be installed at a low position, with low installation difficulty and high safety.

[0090] In some embodiments, the side column 110 is provided with a first ear plate and a second ear plate, the assembly cable 300 is connected to the first ear plate, and the inclined cable 400 is connected to the second ear plate.

[0091] In the related art, the installation process of the photovoltaic bracket is to tension the component cables and install the photovoltaic components on the component cables after the side columns and the center column are installed. The photovoltaic components have certain requirements for the installation height. The installation of photovoltaic components is a high-altitude operation, which is difficult to install, has low installation efficiency and high risks. In addition, the photovoltaic components are heavy, and the cost of lifting them to a high place for installation is high.

[0092] In the photovoltaic bracket 10 of this embodiment, after the side support structure 100 and the middle support structure 200 are installed, the side column 110 is in a first posture, and the component cable 300 is installed on the side column 110. At this time, the component cable 300 has no initial pre-tension and is in a relaxed state. The photovoltaic component 20 is installed on the component cable 300, and the installation difficulty is relatively small. The side column 110 is driven to rotate along the first direction z1 to the second posture. After the component cable 300 reaches a preset height, the lifting and tensioning of the component cable 300 are completed synchronously, the middle part of the component cable 300 is connected to the central beam 220, and the inclined cable 400 is connected to fix the side column 110. There are fewer installation steps, which facilitates the lifting and installation of the photovoltaic component 20. The installation efficiency is high, the cost is low, and there are fewer high-altitude operations, which is safer.

[0093] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting adjustment column feet 120 at the bottom of the side columns 110 at both ends of the photovoltaic bracket 10, the side columns 110 can be rotated along the first direction z1 to facilitate the low-position installation of the component rope 300 and the photovoltaic component 20. The installation difficulty is relatively small, the installation efficiency is relatively high, the cost is relatively low, and the safety is relatively high. At the same time, in the later use process, it is easy to adjust and tension the component rope 300 by rotating the side columns 110, and the stability of the photovoltaic bracket 10 is relatively good.

[0094] In some embodiments, as Figure 8 As shown, the photovoltaic support 10 may further include: a first rotating shaft 510 .

[0095] like Figure 8 As shown, the first rotation axis 510 is hinged to the side column 110 along the second direction z2, and the component cable 300 is hinged to the side column 110 through the first rotation axis 510, and the second direction z2 intersects with the first direction z1.

[0096] In this embodiment, the first rotating shaft 510 can be a pin shaft, and a through hole is provided on the side column 110. The first rotating shaft 510 is installed in the through hole. The axial direction of the first rotating shaft 510 is parallel to the second direction z2, and the second direction z2 is perpendicular to the first direction z1. The first direction z1 is the length direction of the component cable 300. The component cable 300 is hinged to the side column 110 through the first rotating shaft 510. When the side column 110 is rotated, the first rotating shaft 510 will also rotate within a certain range to adjust the component cable 300 and reduce the force in the direction of the component cable 300. The tensioning effect of the component cable 300 remains unchanged, the inclination angle of the photovoltaic component 20 remains unchanged, and the support for the photovoltaic component 20 is better.

[0097] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a first rotating shaft 510 hinged along the second direction z2 is provided so that the component cable 300 can rotate along with the side column 110 when the side column 110 rotates, thereby reducing the force in the direction of the component cable 300 and providing better support.

[0098] In some embodiments, as Figure 8 As shown, the circumference of the first rotating shaft 510 includes an arcuate surface 511 and a flat surface 512 .

[0099] The arcuate surface 511 is used for hinged connection with the side column 110 , and the flat surface 512 is used for installing the anchor of the component cable 300 .

[0100] In this embodiment, the first rotating shaft 510 can be a D-type rotating shaft with a D-shaped cross-section. The circumferential surface of the first rotating shaft 510 includes an arcuate surface 511 and a plane 512. The arcuate surface 511 is used to be hinged to the side column 110 and rotate in the through hole of the side column 110. The plane 512 is used to install the anchor of the component rope 300. In this embodiment, a clip-type anchor, an extrusion-type anchor or other anchors can be used to install the component rope 300.

[0101] It is understandable that the proportion of the arc surface 511 and the flat surface 512 to the circumferential surface can be set according to actual use requirements and is not specifically limited in this embodiment.

[0102] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the circumferential shape of the first rotating shaft 510 , the rotation effect of the first rotating shaft 510 is ensured while the fixing effect of the component cable 300 is better.

[0103] In some embodiments, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10 As shown, the photovoltaic support 10 may further include: a second rotating shaft 520 and a stay cable mounting bracket 600 .

[0104] The stay cable mounting bracket 600 is suitable for installation on a construction ground.

[0105] The stay cable mounting frame 600 may be fixed to the ground by using a stay cable pile foundation, anchor bolts, chemical anchors or other mechanical anchoring systems.

[0106] In this embodiment, the stay cable mounting frame 600 can be installed on the construction ground through the stay cable pile foundation, and has good stability.

[0107] The pile foundation of the inclined cable can be constructed by using pre-set steel piles or cast concrete pile foundations.

[0108] like Figure 9 and Figure 10 As shown, a second rotating shaft 520 is installed at both ends of the inclined cable 400, and both ends of the inclined cable 400 are hinged to the side column 110 and the inclined cable mounting frame 600 through the corresponding second rotating shaft 520.

[0109] In this embodiment, a second rotating shaft 520 is installed at both ends of the inclined cable 400. The second rotating shaft 520 can be a pin shaft. A through hole is provided on the side column 110 and the inclined cable mounting frame 600. The second rotating shaft 520 is installed in the through hole. The axial direction of the second rotating shaft 520 is parallel to the second direction z2, and the second direction z2 is perpendicular to the first direction z1. The first direction z1 is the length direction of the component cable 300. The two ends of the inclined cable 400 are respectively hinged to the side column 110 and the inclined cable mounting frame 600 through the corresponding second rotating shaft 520. When the side column 110 is rotated, the second rotating shaft 520 will also rotate within a certain range to adjust the direction of force on the inclined cable 400.

[0110] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a second rotating shaft 520 hinged along the second direction z2 is provided so that the inclined cable 400 can rotate along with the side column 110 when the side column 110 rotates, thereby reducing the force in the direction of the inclined cable 400 and providing better support.

[0111] In some embodiments, as Figure 9 and Figure 10 As shown, the circumference of the second rotating shaft 520 may include an arcuate surface 511 and a flat surface 512 .

[0112] The arcuate surface 511 is used for being hinged to the side column 110 and the inclined cable mounting bracket 600 , and the flat surface 512 is used for installing the anchor of the inclined cable 400 .

[0113] In this embodiment, the second rotating shaft 520 can be a D-type rotating shaft with a D-shaped cross-section. The circumferential surface of the second rotating shaft 520 includes an arcuate surface 511 and a plane surface 512. The arcuate surface 511 is used to be hinged with the side column 110 and the inclined cable mounting frame 600, and rotate in the through holes of the side column 110 and the inclined cable mounting frame 600. The plane surface 512 is used to install the anchor of the inclined cable 400. In this embodiment, a clip-type anchor, an extrusion-type anchor or other anchor installation component cable 300 can be used.

[0114] It is understandable that the proportion of the arc surface 511 and the flat surface 512 to the circumferential surface can be set according to actual use requirements and is not specifically limited in this embodiment.

[0115] According to the photovoltaic support 10 provided in the embodiment of the present application, by setting the circumferential shape of the second rotating shaft 520, the rotation effect of the second rotating shaft 520 is ensured while the fixing effect of the inclined cable 400 is better.

[0116] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the edge support structure 100 may include: a plurality of edge columns 110 .

[0117] The plurality of side columns 110 are spaced apart and distributed along the second direction z2.

[0118] In this embodiment, the second direction z2 is a direction perpendicular to the length direction of the component cable 300 , and the multiple rows of photovoltaic brackets 10 in the photovoltaic system 1 are also spaced apart and distributed along the second direction z2 .

[0119] The stay cable mounting bracket 600 includes a plurality of stay cable mounting brackets 600 , and the plurality of stay cable mounting brackets 600 are spaced apart and distributed along the second direction z2 .

[0120] The plurality of stay cable mounting frames 600 are connected to the plurality of side columns 110 in a one-to-one correspondence via corresponding stay cables 400 . The angle between the stay cables 400 corresponding to the side columns 110 with a relatively higher height and the horizontal plane is smaller.

[0121] In this embodiment, the side support structure 100 may include two side columns 110, and the two side columns 110 are spaced apart and distributed along the second direction z2. The two inclined cable mounting frames 600 are connected to the two side columns 110 one by one through corresponding inclined cables 400. The two side columns 110 have different heights, and the two inclined cable mounting frames 600 are at different positions along the first direction z1. The inclined cable 400 corresponding to the side column 110 with a higher relative height among the two side columns 110 has a smaller third angle α3 with the horizontal plane, and the component force of the inclined cable 400 acting on the side column 110 is smaller. The side column 110 is not easy to rotate, has better stability, and better support for the photovoltaic module 20.

[0122] In some embodiments, the side support structure 100 may further include a connecting beam 130, which is connected between the two side columns 110. The inclined cable 400 corresponding to the side column 110 with a relatively higher height among the two side columns 110 is connected to the portion of the side column 110 that is higher than the connecting beam 130, and the inclined cable 400 corresponding to the side column 110 with a relatively lower height among the two side columns 110 is connected to the portion of the side column 110 that is lower than the connecting beam 130. The connecting beam 130 bears part of the force of the side columns 110 to improve stability.

[0123] It should be noted that the distance between the position where the inclined cables 400 corresponding to the two side columns 110 are connected to the side columns 110 and the connection beam 130 is within a certain range.

[0124] According to the photovoltaic support 10 provided in the embodiment of the present application, the inclined cables 400 connected by the side columns 110 of different heights are arranged at different inclination angles, so that the side columns 110 are subjected to more reasonable forces, and have better stability and support.

[0125] In some embodiments, as Figure 2 、 Figure 5 and Figure 6As shown, the distance between the stayed cable mounting bracket 600 corresponding to the side column 110 with a higher relative height and the side column 110 along the first direction z1 is greater.

[0126] In this embodiment, the side support structure 100 may include two side columns 110, the two side columns 110 are spaced apart and distributed along the second direction z2, the two inclined cable mounting brackets 600 are connected to the two side columns 110 respectively through corresponding inclined cables 400, the two side columns 110 have different heights, the two inclined cable mounting brackets 600 are at different positions along the first direction z1, and the inclined cable mounting bracket corresponding to the side column 110 with a relatively higher height among the two side columns 110 is the same as the side column 110 with a relatively higher height. The distance between the frame 600 and the side column 110 along the first direction z1 is farther, one end of the inclined cable 400 is connected to the side column 110, and the other end is connected to the inclined cable mounting frame 600. The inclined cable 400 corresponding to the side column 110 with a higher relative height among the two side columns 110 has a smaller third angle α3 with the horizontal plane, and the component force of the inclined cable 400 acting on the side column 110 is smaller. The side column 110 is not easy to rotate, has better stability, and better support for the photovoltaic module 20.

[0127] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the inclined cable mounting frame 600 at different positions along the first direction z1, the inclined cables 400 connected to the side columns 110 of different heights can be tilted at different angles, thereby improving the stability and support of the side columns 110.

[0128] In some embodiments, as Figure 11 As shown, the photovoltaic support 10 may further include a temporary support frame 700 .

[0129] The temporary support frame 700 is suitable for being arranged near the center column 210 , and is used to support the component cables 300 when the component cables 300 are installed.

[0130] In this embodiment, the temporary support frame 700 is arranged at the bottom of the center column 210. When the component cable 300 is installed at a low position, the middle part of the component cable 300 can be supported on the temporary support frame 700. The temporary support frame 700 can ensure that the component cable 300 has a certain initial height during installation, providing operating space for the installation of the photovoltaic component 20. At the same time, the temporary support frame 700 can bear the weight of the component cable 300 and the photovoltaic component 20, ensuring that the component cable 300 can complete the tensioning.

[0131] Exemplarily, a groove may be provided above the temporary support frame 700 for supporting the assembly cable 300 .

[0132] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a temporary support frame 700 is set near the central column 210 to provide an operating space for the installation of the photovoltaic component 20 when the component cable 300 is installed. At the same time, the temporary support frame 700 can bear the weight of the component cable 300 and the photovoltaic component 20 to assist in the tensioning of the component cable 300.

[0133] The embodiment of the present application also provides a photovoltaic system 1 .

[0134] like Figure 1 and Figure 2 As shown, the photovoltaic system 1 includes: a photovoltaic bracket 10 and a photovoltaic component 20.

[0135] The photovoltaic bracket 10 is the photovoltaic bracket 10 of the above embodiment.

[0136] The photovoltaic module 20 is installed on the module cable 300 .

[0137] In this embodiment, the photovoltaic system 1 includes multiple rows of photovoltaic supports 10. After the side support structures 100 and the middle support structures 200 of each row are installed, the side columns 110 are in a first posture, and the component cables 300 are installed on the side columns 110. At this time, the component cables 300 have no initial pre-tension and are in a relaxed state. Multiple groups of photovoltaic components 20 are installed on the component cables 300, and the installation difficulty is relatively low. The side columns 110 are driven to rotate along the first direction z1 to the second posture, so that the component cables 300 reach a preset height. The lifting and tensioning of the component cables 300 are completed synchronously, and the middle part of the component cables 300 is connected to the central beam 220. The inclined cables 400 are connected to fix the side columns 110. There are fewer installation steps, which facilitates the lifting and installation of multiple groups of photovoltaic components 20. The installation efficiency is high, the cost is low, and there are fewer high-altitude operations, which is safer.

[0138] According to the photovoltaic system 1 provided in the embodiment of the present application, by setting adjustment column feet 120 at the bottom of the side columns 110 at both ends of each row of photovoltaic brackets 10, the side columns 110 can be rotated along the first direction z1 to facilitate the low-position installation of the component rope 300 and multiple groups of photovoltaic components 20. The installation difficulty is relatively small, the installation efficiency is relatively high, the cost is relatively low, and the safety is relatively high. At the same time, in the later use process, it is easy to adjust and tension the component rope 300 by rotating the side columns 110, and the stability of the photovoltaic bracket 10 is relatively good.

[0139] The embodiment of the present application also provides a construction method.

[0143] Step 930 : When the side column 110 is in the first posture, install the component cable 300 and the photovoltaic component 20 .

[0144] In this embodiment, the side column 110 is in a first posture, and the component cable 300 is installed on the side column 110. At this time, the component cable 300 has no initial pre-tension and is in a relaxed state. A plurality of photovoltaic components 20 are installed on the component cable 300. When installing, the photovoltaic components 20 are installed symmetrically from the middle of the component cable 300 to both sides, and the installation difficulty is relatively small.

[0145] Step 950 : Rotate and tension the side column 110 to a second posture, and install the component cable 300 on the center beam 220 .

[0146] In this embodiment, auxiliary equipment is set near the side column 110 to slowly push the side column 110 to the second posture. At the same time, the position of the middle column 210 can be assisted by lifting equipment such as a forklift or a crane, and the component cable 300 and the middle beam 220 are installed and locked by fasteners.

[0147] The auxiliary equipment provided near the side column 110 may be a hydraulic cylinder, a traction tool, a winch or an excavator.

[0148] Step 970: Fix the stay cable 400.

[0149] In this embodiment, after the assembly cables 300 at the center beam 220 are installed, the stay cables 400 at the side columns 110 are installed and fastened.

[0150] According to the construction method provided in the embodiment of the present application, by setting adjustment column feet 120 at the bottom of the side columns 110 at both ends of the photovoltaic bracket 10, the side columns 110 can be rotated along the first direction z1 to facilitate the low-position installation of the component rope 300 and the photovoltaic component 20. The installation difficulty is relatively small, the installation efficiency is relatively high, the cost is relatively low, and the safety is relatively high. At the same time, in the later use process, it is easy to adjust and tension the component rope 300 by rotating the side columns 110, and the stability of the photovoltaic bracket 10 is relatively good.
