[0076] 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.

[0077] The principle of the photovoltaic bracket 10 proposed in this application is described in detail below:

[0078] 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.

[0079] In order to solve this technical problem, the present application provides a photovoltaic bracket 10, which is referred to below. Figures 1-15 A photovoltaic bracket 10 according to an embodiment of the present application is described.

[0080] like Figure 1 As shown, the photovoltaic bracket 10 of the embodiment of the present application includes: a side support structure 100, a middle support structure 200 and a component cable 300.

[0081] like Figure 2 As shown, the edge support structure 100 includes an edge column 110 and a first adjustment column foot 120 .

[0082] 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.

[0083] 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.

[0084] like Figure 2 As shown, the first adjustment column foot 120 is installed at the bottom of the side column 110.

[0085] In this embodiment, the first adjustment column foot 120 can rotate with multiple degrees of freedom, including but not limited to rotation along the length direction of the component cable 300 and rotation along a direction perpendicular to the length direction of the component cable 300.

[0086] like Figure 10 As shown, the middle support structure 200 includes a middle column 210 , a second adjustment column foot 230 and a middle beam 220 .

[0087] The material of the center column 210 may be the same as or different from that of the side columns 110 .

[0088] like Figure 10 As shown, the second adjustment column foot 230 and the center beam 220 are respectively installed at both ends of the center column 210.

[0089] In this embodiment, after the center beam 220 is installed on the center column 210, the length direction of the center beam 220 can form a certain angle with the ground according to usage requirements, so that after the component cable 300 is installed on the center beam 220, the photovoltaic component 20 can better receive light.

[0090] like Figure 2 As shown, the second adjustment column foot 230 can rotate along the first direction z1 and the second direction z2.

[0091] In this embodiment, the second adjustment column foot 230 can rotate with multiple degrees of freedom. The first direction z1 can be the length direction of the component cable 300, and the second direction z2 can be a direction perpendicular to the length direction of the component cable 300.

[0092] The first adjusting column foot 120 and the second adjusting column foot 230 may be ball joints or other hinge structures.

[0093] The component cable 300 is used to connect between the side support structures 100 at both ends of the photovoltaic bracket 10 , and the component cable 300 is connected to the center beam 220 , and the photovoltaic component 20 is installed on the component cable 300 .

[0094] In this embodiment, the component cable 300 passes through the middle beam 220 of the center column 210 and is connected to the side columns 110 at both ends of the photovoltaic support 10 respectively.

[0095] 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 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 photovoltaic component is large in size and weight, resulting in low installation efficiency, high cost, and greater risk.

[0096] After the photovoltaic bracket 10 of this embodiment is installed, the side columns 110 of the side support structure 100 and the center column 210 of the middle support structure 200 are rotated, the first adjustment column foot 120 and the second adjustment column foot 230 are rotated so that the side columns 110 and the center column 210 are close to the ground, and the component cable 300 is reserved for tensioning, and the component cable 300 is connected to the center beam 220 and the side columns 110 at both ends of the photovoltaic bracket 10, and the photovoltaic component 20 is installed on the component cable 300. After the photovoltaic component 20 is installed, the first adjustment column foot 120 and the second adjustment column foot 230 are rotated. The tensioning side column 110 is rotated to a preset height, and the middle column 210 rotates along with the side column 110, driving the component rope 300 and the photovoltaic component 20 to be lifted to a high position and then fixing the side column 110 to complete the installation of the photovoltaic component 20. The installation efficiency is high, and there is no need to use lifting tools to lift the workers and the photovoltaic component 20 to a high position for construction. The cost and risk are low. The installation work of the component rope 300 and the photovoltaic component 20 is completed at a low position, and the component rope 300 is tensioned synchronously, which makes the tensioning of the component rope 300 easier.

[0097] It should be noted that when the first adjustment column foot 120 and the second adjustment column foot 230 are rotated so that the side column 110 and the center column 210 are close to the ground, the rotation direction can be a direction perpendicular to the length direction of the component rope 300, and the side column 110 and the center column 210 can be rotated until the length direction is parallel to the ground.

[0098] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the first adjustment column foot 120 and the second adjustment column foot 230, the side column 110 and the middle column 210 can be rotated to a lower position to install the component rope 300 and the photovoltaic component 20, which has high installation efficiency, less high-altitude work, and low cost and risk.

[0099] In some embodiments, the photovoltaic support 10 may further include a component cable connector 400 .

[0100] like Figure 2 and Figure 3 As shown, the component cable connector 400 is rotatably assembled on the side column 110 around the first rotation axis l1 , and the component cable 300 is connected to the component cable connector 400 .

[0101] In this embodiment, the component cable connector 400 is installed on the side column 110, and the component cable 300 is connected to the component cable connector 400. The component cable connector 400 can rotate around the first rotation axis l1 to facilitate the component cable 300 to rotate and adjust the angle of the photovoltaic component 20, thereby realizing the photovoltaic bracket 10 tracking the light.

[0102] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the component cable connector 400 on the side column 110, the component cable 300 is rotated to adjust the angle of the photovoltaic component 20, so that the photovoltaic bracket 10 can track the light and have a higher power generation efficiency.

[0103] In some embodiments, the component cable connector 400 may include a first mounting portion 410 and a first connecting portion 420 .

[0104] like Figure 2 and Figure 3 As shown, the first mounting portion 410 is mounted on the side column 110 , the first connecting portion 420 is rotatably assembled on the first mounting portion 410 around the first rotation axis l1 , and the assembly cable 300 is connected to the first connecting portion 420 .

[0105] In this embodiment, the first mounting portion 410 can be a through bolt, which passes through the side column 110 and the first connecting portion 420. The component cable 300 is connected to the first connecting portion 420. The first connecting portion 420 can rotate around the first rotation axis l1. When the first connecting portion 420 rotates, it drives the component cable 300 to rotate, so that the component cable 300 can rotate to adjust the angle of the photovoltaic component 20, thereby realizing the tracking of light by the photovoltaic bracket 10.

[0106] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the first mounting portion 410 and the first connecting portion 420, the component cable connector 400 is rotated around the first rotation axis l1, so that the component cable 300 can rotate to adjust the angle of the photovoltaic component 20, thereby realizing the photovoltaic bracket 10 tracking the light and having a higher power generation efficiency.

[0107] In some embodiments, the photovoltaic support 10 may further include a stay cable 500 and a stay cable connector 600 .

[0108] like Figure 2 and Figure 3 As shown, the inclined cable connector 600 is rotatably assembled on the side column 110 around the second rotation axis l2, one end of the inclined cable 500 is connected to the inclined cable connector 600, and the other end of the inclined cable 500 is connected to the construction ground.

[0109] In this embodiment, the inclined cable connector 600 is installed on the side column 110, one end of the inclined cable 500 is connected to the inclined cable connector 600, and the other end of the inclined cable 500 is connected to the construction ground. After the inclined cable 500 is connected to the inclined cable connector 600, when the side column 110 is rotated from a low position to a preset height, the inclined cable connector 600 can rotate relative to the side column 110 around the second rotation axis l2, thereby avoiding the twisting of the side column 110 caused by the angle change during the tensioning process, which may damage the structure of the photovoltaic bracket 10.

[0110] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the inclined cable connector 600 is arranged to be rotatably assembled on the side column 110 around the second rotation axis l2, thereby preventing the side column 110 from being twisted by the inclined cable 500 during the process of rotating and tensioning the side column 110, and having better stability.

[0111] In some embodiments, the stay cable connector 600 may include a second mounting portion 610 and a second connecting portion 620 .

[0112] like Figure 2 and Figure 3 As shown, a plurality of second connection parts 620 may be provided.

[0113] The second mounting portion 610 is rotatably mounted on the side column 110 around the second rotation axis l2. A plurality of second connecting portions 620 are spaced apart on the second mounting portion 610. One end of the inclined cable 500 is connected to the second connecting portion 620, and the other end of the inclined cable 500 is connected to the construction ground.

[0114] In this embodiment, the second mounting portion 610 can be a tubular structure, and the second mounting portion 610 is installed on the side column 110. Multiple second connecting portions 620 are arranged at intervals on the outer wall of the second mounting portion 610. One end of the inclined cable 500 is connected to one of the second connecting portions 620, and the other end of the inclined cable 500 is connected to the construction ground. When the side column 110 is rotated from a low position to a preset height, the second mounting portion 610 can rotate relative to the side column 110 around the second rotation axis l2 to avoid twisting of the side column 110 caused by angle changes during tensioning, which may damage the structure of the photovoltaic bracket 10.

[0115] In some embodiments, there may be two inclined cables 500 symmetrically arranged about the side column 110. One end of the inclined cable 500 is pre-connected to the second mounting portion 610, and the other end of the inclined cable 500 is connected to the anchor pile on the construction ground after the side column 110 and the component cable 300 are rotated and tensioned. After installation, the inclined cable 500 is in a straight state.

[0116] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by setting the second mounting portion 610 and the second connecting portion 620, the inclined cable connector 600 can be rotated around the second rotation axis l2, thereby preventing the side column 110 from being twisted by the inclined cable 500 during the process of rotating the tensioned side column 110, and having better stability.

[0117] In some embodiments, as Figure 4 As shown, the first adjustment column foot 120 may be provided with an inclined surface 121 .

[0118] The inclined surface 121 is connected to the construction ground, and an angle is formed between the inclined surface 121 and the construction ground.

[0119] In this embodiment, the first adjustment column foot 120 may include a connecting rod 122 and an inclined surface 121. One end of the connecting rod 122 is connected to the bottom of the side column 110, and the other end of the connecting rod 122 is hinged to the inclined surface 121. The inclined surface 121 is installed on the construction ground or pile foundation, and an angle is formed between the inclined surface 121 and the horizontal plane of the construction ground or pile foundation. The connecting rod 122 can be rotated in a direction perpendicular to the component cable 300 to a low position to install the component cable 300 and the photovoltaic component 20.

[0120] It should be noted that the specific angle formed between the inclined surface 121 and the horizontal plane of the construction ground or the pile foundation is determined according to the actual installation requirements. The angle in this embodiment is determined by calculating the reserved length of the component cable 300, and the angle can be between 30 and 70 degrees. Since the inclined surface 121 has a preset angle, the side column 110 also has a preset angle with the ground. After the component cable 300 and the photovoltaic component 20 are installed, the side column 110 is rotated to a preset height in a direction perpendicular to the component cable 300, and the tensioning of the component cable 300 is completed synchronously.

[0121] In some embodiments, the first adjustment column foot 120 may also be hinged to the construction ground or pile foundation only through the ball joint of the connecting rod 122 to achieve multi-angle rotation of the side column 110.

[0122] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a slope 121 having a certain angle with the construction ground is set on the first adjustment column foot 120, so that the component rope 300 can be tensioned synchronously after the side column 110 is rotated to a preset height, which has high installation efficiency and low cost.

[0125] In this embodiment, the first adjustment column foot 120 is installed at the bottom of the side column 110, and the first adjustment column foot 120 is hinged to the side pile foundation 710. The first adjustment column foot 120 can rotate with multiple degrees of freedom, including but not limited to rotation along the length direction of the component cable 300 and rotation along a direction perpendicular to the length direction of the component cable 300.

[0126] like Figure 1 and Figure 10 As shown, the second adjustment column foot 230 is connected to the construction ground through the middle pile foundation 720.

[0127] In this embodiment, the second adjustment column foot 230 is installed at the bottom of the central column 210, and the second adjustment column foot 230 is hinged to the middle pile foundation 720. The second adjustment column foot 230 can rotate with multiple degrees of freedom, including but not limited to rotation along the length direction of the component cable 300 and rotation along a direction perpendicular to the length direction of the component cable 300.

[0128] like Figure 1 、 Figure 2 、 Figure 5-Figure 7 and Figure 9 As shown, the stay cable 500 is connected to the construction ground via a stay cable pile foundation 730 .

[0129] In this embodiment, two inclined cable pile foundations 730 are symmetrically arranged about the side column 110, one end of the inclined cable 500 is pre-connected to the second mounting portion 610, and the other end of the inclined cable 500 is connected to the inclined cable pile foundation 730 after the side column 110 and the component cable 300 are rotated and tensioned.

[0130] The side pile foundations 710 , the middle pile foundation 720 and the cable-stayed pile foundation 730 may be steel piles, concrete pile foundations or other forms of pile foundations, which are not specifically limited in this embodiment.

[0131] According to the photovoltaic support 10 provided in the embodiment of the present application, by setting the side pile foundation 710, the middle pile foundation 720 and the inclined cable pile foundation 730, it is convenient to hinge the first adjustment column foot 120 and the second adjustment column foot 230 and connect the inclined cable 500.

[0134] The photovoltaic bracket 10 is the photovoltaic bracket 10 of the above embodiment.

[0135] The photovoltaic module 20 is installed on the module cable 300 .

[0136] In this embodiment, after the side columns 110 of the side support structure 100 and the center column 210 of the middle support structure 200 are installed, the first adjustment column foot 120 and the second adjustment column foot 230 are rotated so that the side columns 110 and the center column 210 are close to the ground. After the component cable 300 reserves a tensioning margin, the component cable 300 is connected to the center beam 220 and the side columns 110 at both ends of the photovoltaic bracket 10. Multiple groups of photovoltaic components 20 are installed on the component cable 300. After the photovoltaic components 20 are installed, the tensioning is rotated. Pull the side column 110 to a preset height, and the middle column 210 rotates along with the side column 110, driving the component cable 300 and the photovoltaic component 20 to rise, and fix them after rising to a suitable height, completing the installation of the photovoltaic component 20. The installation of the component cable 300 and the photovoltaic component 20 is completed at a low position, and the component cable 300 is tensioned synchronously. The tensioning of the component cable 300 is easier, and the installation efficiency is higher. There is no need to lift the workers and the photovoltaic component 20 to a high place for construction using lifting tools, and the cost and risk are lower.

[0137] According to the photovoltaic system 1 provided in the embodiment of the present application, the component rope 300 and multiple groups of photovoltaic components 20 can be installed by rotating the side columns 110 and the center column 210 of the photovoltaic bracket 10 to a low position. The side columns 110 are rotated to a preset height, and the center column 210 follows the rotation of the side columns 110 to complete the installation of multiple groups of photovoltaic components 20. The installation is simple, safe, low-cost, and has high power generation efficiency.

The component cable support rods 30 of multiple rows of photovoltaic systems 1 are connected by inter-row tie rods 40, and the inter-row tie rods 40 are rotatably connected to the component cable support rods 30. When the component cables 300 of a group of photovoltaic brackets 10 adjust their angles, the inter-row tie rods 40 will rotate synchronously, so that the component cables 300 of other rows of photovoltaic brackets 10 of the photovoltaic system 1 will follow and rotate to the same angle, so that they can better receive light. The photovoltaic system 1 has high power generation efficiency and is easy to operate.

[0141] It should be noted that the inter-row tie rods 40 and the component cable support rods 30 are parallelograms, which can simultaneously achieve angle adjustment of multiple rows of photovoltaic brackets 10 within a certain range, while enhancing the integrity of the photovoltaic bracket 10 structure and improving the wind resistance of the photovoltaic system 1.

[0142] According to the photovoltaic system 1 provided in the embodiment of the present application, by arranging component cable supports 30 on the photovoltaic brackets 10 and arranging inter-row tie rods 40 between the component cable supports 30 of multiple rows of photovoltaic systems 1, synchronous angle adjustment of the photovoltaic brackets 10 of multiple rows of photovoltaic systems 1 is achieved.
