[0076] like Figure 7 As shown, the middle support structure 200 includes a middle column 210 and a middle mounting frame 220 .

[0077] The center column 210 is suitable for installation on the construction ground.

[0081] Exemplarily, the middle mounting frame 220 includes a middle beam 221, a first rod 222 and two second rods 223. The middle beam 221 is used to connect the component rope 300. One end of the first rod 222 is connected to the middle beam 221, and the other end of the first rod 222 is hinged to the support 230. The middle beam 221 has a better rotation effect. The two second rods 223 are arranged on both sides of the first rod 222, and the two second rods 223 are connected to the middle of the first rod 222.

[0085] First, as Figure 6 and Figure 7 As shown, the side mounting frame 120 is provided with a component cable support lug, and the middle mounting frame 220 is provided with a component cable support.

[0086] In this embodiment, the component cable 300 is anchored to the component cable lug of the side mounting frame 120 by an anchor, and the middle portion of the component cable 300 is supported by the component cable support of the middle mounting frame 220 .

[0087] Secondly, the side mounting frames 120 and the middle mounting frame 220 are provided with component cable support ears.

[0088] In this embodiment, the component cable 300 is anchored to the component cable lugs of the side mounting frame 120 and the middle mounting frame 220 by means of anchors.

[0089] 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 support structure and the middle support structure are installed. The lower edge of the photovoltaic component is set at a certain height from the ground, which makes the installation of the photovoltaic component a high-altitude operation. The installation construction is relatively difficult, and the volume and weight of the photovoltaic component are large, the installation efficiency is low, the cost is high, and the risk is greater.

[0090] The photovoltaic bracket 10 of this embodiment, the side bracket 110 and the center column 210 are installed on the construction ground, the side mounting frame 120 and the middle mounting frame 220 are in a position close to the construction ground, the component rope 300 is installed on the side mounting frame 120 and the middle mounting frame 220, and the photovoltaic component 20 is installed on the component rope 300.

[0093] The first rotation axis l1 and the second rotation axis l2 are parallel to the length direction of the component cable 300 .

[0094] In this embodiment, the side mounting frame 120 is hinged to the side bracket 110, and the side bracket 110 is provided with a through hole. The side mounting frame 120 is rotatably connected to the through hole around the first rotation axis l1, and the middle mounting frame 220 is hinged to the support 230 of the center column 210 around the second rotation axis l2. The first rotation axis l1 and the second rotation axis l2 are parallel to the length direction of the component rope 300, and the side mounting frame 120 and the middle mounting frame 220 rotate synchronously to a preset height.

[0095] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the first rotation axis l1 and the second rotation axis l2 are set to be parallel to the length direction of the component cable 300, so that the side mounting frame 120 and the middle mounting frame 220 can be rotated synchronously to a preset height.

[0096] In some embodiments, the edge mounting bracket 120 may include: a connecting piece.

[0097] There are multiple connecting pieces, which are connected to each other. The multiple connected connecting pieces respectively form edges of the tetrahedron structure.

[0098] The cross-section of the connector can be circular, rectangular, triangular or polygonal, and the shape can be customized to meet specific installation needs and design requirements.

[0099] In this embodiment, Figure 6 As shown, multiple connected connectors respectively constitute the edges of the tetrahedron structure, one connector is used to install the component rope 300, one connector is used to be hinged to the edge bracket 110, and the remaining four connectors are connected between these two connectors to form a tetrahedron structure, which can evenly disperse stress and has better stability.

[0100] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the edge mounting frame 120 is provided with a tetrahedron structure composed of a plurality of connected connectors, so that the edge mounting frame 120 has better stability.

[0101] In some embodiments, the plurality of connected connectors may include: a first connector 121 , a second connector 122 and a plurality of third connectors 123 .

[0102] In this embodiment, the number of the third connecting members 123 is four.

[0103] like Figure 6 As shown, the component cable 300 is connected to the first connecting member 121 , the second connecting member 122 is hinged to the edge bracket 110 , and the two ends of the first connecting member 121 and the two ends of the second connecting member 122 are connected via four third connecting members 123 .

[0104] In this embodiment, the first connecting member 121 is provided with a lifting hole and a component rope 300 support ear, the component rope 300 is connected to the component rope 300 support ear of the first connecting member 121, and the second connecting member 122 is rotatably connected to the through hole of the edge bracket 110. The two ends of the first connecting member 121 are respectively connected to one end of two third connecting members 123, and the two ends of the second connecting member 122 are respectively connected to one end of two third connecting members 123 to form a tetrahedron structure.

[0105] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the number and connection method of the first connecting member 121, the second connecting member 122 and the third connecting member 123 are set so that the edge mounting frame 120 forms a stable tetrahedron structure.

[0106] In some embodiments, as Figure 5 and Figure 6 As shown, the side bracket 110 may include two lower supports 111 .

[0107] The two lower supports 111 are arranged opposite to each other.

[0108] In this embodiment, the two lower supports 111 are provided along the length direction of the component cable 300 .

[0109] The lower support 111 can be installed on the construction ground by means of a pre-set steel pile foundation or a cast concrete pile foundation, or can be directly installed on the construction ground.

[0110] The side mounting frame 120 is hinged to the two lower supports 111 .

[0111] In this embodiment, a through hole is provided on the upper portion of the two lower supports 111, and the second connecting member 122 of the edge mounting frame 120 is rotatably connected to the through hole of the lower support 111. The edge mounting frame 120 can rotate around the first rotation axis l1 between the two through holes, and the first rotation axis l1 is parallel to the length direction of the component cable 300.

[0112] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting two relatively arranged lower supports 111, the stability of the side support structure 100 is better, and when the side mounting frame 120 rotates, the side bracket 110 is not easy to fall over.

[0113] In some embodiments, as Figure 6 As shown, the edge support structure 100 may further include a blocking rod 130 .

[0114] The blocking rod 130 is connected between the two lower supports 111 , and is used to support the edge mounting frame 120 .

[0115] In this embodiment, the second connecting member 122 is hinged to the side bracket 110, the height of the blocking rod 130 is lower than the height of the second connecting member 122, and when the side mounting frame 120 is in a naturally tilted state, the height of the blocking rod 130 is higher than the height of the lowest end of the first connecting member 121, so that the side mounting frame 120 can be leaned against the blocking rod 130 in a naturally tilted state. When the side mounting frame 120 is leaning against the blocking rod 130, the installation and tensioning of the component rope 300 and the installation of the photovoltaic component 20 can be carried out near the construction ground.

[0116] According to the photovoltaic support 10 provided in the embodiment of the present application, a barrier rod 130 is provided between the two lower supports 111 to facilitate support when the side mounting frame 120 is not in use and when the component cable 300 is installed near the construction ground.

[0117] In some embodiments, as Figure 3 、 Figure 5 and Figure 6 As shown, the upper portions of the two lower supports 111 are closer to the side mounting brackets 120 than the lower portions.

[0118] In this embodiment, in the extension direction of the component cable 300, the upper parts of the two lower supports 111 are closer to the side mounting frame 120 than the lower parts, and the two lower supports 111 are tilted with the upper parts toward the side mounting frame 120. The side supports 110 along the length direction of the component cable 300 form a triangular structure. At the same time, the lower supports 111 of the side supports 110 along the direction perpendicular to the length direction of the component cable 300 are also triangular structures. The photovoltaic bracket 10 has good stability during use.

[0119] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the photovoltaic bracket 10 has better stability by setting the upper portion of the lower support 111 to be inclined toward the side mounting frame 120 compared to the lower portion.

[0120] In some embodiments, each lower support 111 may include: a plurality of rods 1111 .

[0121] like Figure 5 As shown, multiple rods 1111 are connected end to end, and the multiple rods 1111 are connected to form a polygonal structure.

[0122] The multiple rods 1111 can be connected to form a triangle, a quadrilateral or other polygonal structures.

[0123] In this embodiment, multiple rods 1111 can be connected into a triangular structure, two of the three vertices of the triangular structure are respectively connected to two pile foundations, and the other vertex of the triangular structure is hinged to the edge mounting frame 120, which has better stability, uses less structural materials, and has lower cost.

[0124] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the lower support 111 is provided as a polygonal structure formed by connecting multiple rods 1111, thereby improving stability and reducing costs.

[0129] One end of the support rod 140 is connected to the side bracket 110 , and the other end of the support rod 140 is connected to the side mounting bracket 120 .

[0130] In this embodiment, the support rod 140 can adopt a hydraulically adjustable support rod 140. After the side mounting frame 120 is rotated to a preset height, one end of the support rod 140 is connected to the side bracket 110, and the other end of the support rod 140 is connected to the side mounting frame 120. The side mounting frame 120 is fixed, and the inclination angle of the photovoltaic component 20 is also fixed at the same time. When there is a need to adjust the inclination angle of the photovoltaic component 20, the inclination angle of the photovoltaic component 20 can be adjusted in a small range by changing the length of the hydraulically adjustable support rod 140, so as to better receive light and have higher power generation efficiency.

[0161] According to the construction method provided in the embodiment of the present application, by tensioning the component cable 300 to a preset tension, the bearing capacity of the component cable 300 is improved, and the stability is better when installing and lifting the photovoltaic component 20.

[0162] In some embodiments, as Figure 11 As shown, step 590, fixing the edge mounting frame 120, may include:

[0163] Step 591 : Install the support rod 140 between the edge mounting frame 120 and the edge support 110 to fix the edge mounting frame 120 .

[0164] In this embodiment, one end of the support rod 140 is connected to the edge mounting frame 120 , and the other end of the support rod 140 is connected to the edge bracket 110 . The support rod 140 fixes the support angle of the edge mounting frame 120 and the inclination angle of the photovoltaic module 20 .
