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.

[0078] The principle of the photovoltaic bracket 10 proposed in this application is described in detail below:

[0079] 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.

[0080] In order to solve this technical problem, the present application provides a photovoltaic bracket 10, which is referred to below. Figures 1-16 A photovoltaic bracket 10 according to an embodiment of the present application is described.

[0081] like Figures 1-6 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.

[0082] like Figure 1-Figure 7 As shown, the edge support structure 100 includes edge columns 110 and edge beams 120 .

[0083] 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.

[0084] 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.

[0085] The side column 110 is fixed to the ground by pouring concrete, using anchor bolts, chemical anchoring agents or other mechanical anchoring systems. In this embodiment, the side column 110 can be fixed to the ground by pile foundation 600, which has good stability.

[0086] It should be noted that if Figure 1-Figure 7 As shown, considering the flood level and the passability under the photovoltaic module, when the side column 110 is fixed to the ground through the pile foundation 600, the height of the side column 110 is higher than the pile foundation 600.

[0087] The side beam 120 is slidably assembled on the side column 110 along the height direction of the side column 110 .

[0088] like Figures 1-6 and Figure 10 As shown, the central support structure 200 includes a central pillar 210 and a central beam 220 .

[0089] 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.

[0090] 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.

[0091] The center beam 220 is installed on the center column 210 , and the center beam 220 is used to install the component cable 300 .

[0092] In this embodiment, after the center beam 220 is installed on the center column 210 , the length direction of the center beam 220 forms a certain angle with the ground, so that the photovoltaic assembly 20 can better receive light.

[0093] The component cable 300 is used to connect between the side beams 120 at both ends of the photovoltaic support 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 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.

[0095] In the photovoltaic bracket 10 of 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 side beams 120 are installed on the side columns 110, and the component cables 300 are connected between the side beams 120 at both ends of the photovoltaic bracket 10. The photovoltaic components 20 are installed on the component cables 300. The side beams 120 slide along the height direction of the side columns 110, driving the component cables 300 and the photovoltaic components 20 to be lifted to a high place. The component cables 300 are installed on the center beams 220 on the center columns 210 to complete the installation of the photovoltaic components 20.

[0096] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by arranging slidingly assembled side beams 120 on the side columns 110 at both ends of the photovoltaic bracket 10, the side beams 120 drive the component rope 300 and the photovoltaic component 20 to be lifted from a low position to a high position, the installation difficulty is relatively small, the installation efficiency is relatively high, the cost is relatively low, and the safety is relatively high.

[0097] In some embodiments, as Figure 11 and Figure 12 As shown, the side beam 120 may include a side beam body 121 and a sliding portion 122 .

[0098] like Figure 3-Figure 9 As shown, the side beam body 121 is used to connect the component cables 300 .

[0099] The side beam body 121 can be made of a variety of structures and materials. In this embodiment, the side beam body 121 can be made of H-shaped steel, which has high bending resistance and load-bearing capacity and low cost.

[0100] The side beam body 121 is provided with a mounting portion for connecting the component cable 300. In this embodiment, the mounting portion may be a through hole. After the component cable 300 passes through the through hole, it is fixed by an anchor.

[0101] The sliding portion 122 is mounted on the side beam body 121 . The sliding portion 122 is slidably assembled on the side column 110 along a height direction of the side column 110 .

[0102] According to the photovoltaic support 10 provided in the embodiment of the present application, by providing the side beam body 121 and the sliding portion 122 , it is convenient to connect the component cable 300 and slide it on the side column 110 .

[0103] In some embodiments, as Figure 11 and Figure 12 As shown, the side beam body 121 may be provided with a support ear 123 .

[0104] The lug 123 can be made of carbon steel, stainless steel, bronze alloy or composite material. In this embodiment, the lug 123 can be made of stainless steel, which has good corrosion resistance and high strength.

[0105] The support ear 123 is connected to the side beam body 121 to form a whole.

[0106] like Figure 11 and Figure 12 As shown, the sliding portion 122 is mounted on the lug 123 .

[0107] In this embodiment, the sliding portion 122 may be a roller, which is fixedly connected to the support ear 123 via a roller shaft, and the roller can rotate around the roller shaft.

[0108] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a support ear 123 is provided on the side beam body 121, and the sliding part 122 is installed on the support ear 123. The installation of the sliding part 122 is simple, and the side beam body 121 can leave a certain distance from the side column 110 to avoid interference between the side beam 120 and the side column 110 when the sliding part 122 moves.

[0109] In some embodiments, as Figure 7 As shown, the edge support structure 100 may include two edge columns 110 .

[0110] like Figure 11 and Figure 12 As shown, the side beam 120 may include a side beam body 121 and a sliding portion 122 .

[0111] The side beam body 121 can be made of a variety of structures and materials. In this embodiment, the side beam body 121 can be made of H-shaped steel, which has high bending resistance and load-bearing capacity and low cost.

[0112] The sliding parts 122 are mounted on both ends of the side beam body 121 .

[0113] In this embodiment, the sliding portion 122 may be two rollers, which are fixedly connected to the support lug 123 via a roller shaft. The rollers can rotate around the roller shaft. The two rollers are respectively mounted at both ends of the side beam body 121 .

[0114] The side beam body 121 is used to connect the component cables 300. In this embodiment, a through hole is provided on the side beam body 121 for connecting the component cables 300. After the component cables 300 pass through the through hole, they are fixed by anchors.

[0115] The sliding parts 122 are slidably assembled on the side column 110 along the height direction of the side column 110 , and the rotation axes of the two sliding parts 122 are not parallel to the length direction of the side beam body 121 .

[0116] In this embodiment, support ears 123 are installed at both ends of the side beam body 121, and the sliding parts 122 are installed on the support ears 123. The two sliding parts 122 are clamped between the two side columns 110, and the two sliding parts 122 can slide along the height direction of the side columns 110. The rotation axis of the two sliding parts 122 is not parallel to the length direction of the side beam body 121, so that the side beam body 121 has a certain inclination angle. After the component cable 300 is connected to the side beam body 121, the photovoltaic component 20 is installed on the component cable 300. Since the side beam body 121 has a certain inclination angle, the photovoltaic component 20 also has a inclination angle, which can better track the light and has a higher power generation efficiency.

[0117] According to the photovoltaic bracket 10 provided in the embodiment of the present application, two sliding parts 122 are provided to be slidably assembled on the two side columns 110, and the rotation axes of the two sliding parts 122 are not parallel to the length direction of the side beam body 121, so that the side beam body 121 has a certain inclination angle, which helps the photovoltaic component 20 to also have a inclination angle, so that it can better track the light and have a higher power generation efficiency.

[0118] In some embodiments, as Figure 8 As shown, the side column 110 may be provided with a limiting structure 400 .

[0119] The limiting structure 400 is used to lock the side beam 120 .

[0120] In this embodiment, after the sliding portion 122 is slidably assembled on the side column 110, the component cable 300 is connected to the side beam body 121, and the photovoltaic component 20 is installed on the component cable 300. The sliding portion 122 slides along the height direction of the side column 110, and after the component cable 300 and the photovoltaic component 20 are lifted to a suitable height, the sliding portion 122 of the side beam 120 is locked by the limiting structure 400.

[0121] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the limiting structure 400 is provided to lock the side beam 120, thereby facilitating the fixing of the photovoltaic assembly 20 to facilitate photovoltaic power generation and having better stability.

[0122] In some embodiments, as Figure 8 As shown, the limiting structure 400 may include a base plate 410 and a limiting member 420 .

[0123] The substrate 410 can be made of materials such as steel, aluminum alloy and composite materials.

[0124] In this embodiment, the substrate 410 can be made of stainless steel. The substrate 410 made of stainless steel has good corrosion resistance and high strength, and is low in cost.

[0125] The limiting members 420 are installed at both ends of the base plate 410 .

[0126] The base plate 410 is mounted on the side column 110 , and the limiting member 420 is used to clamp the sliding portion 122 .

After the side beam 120 is lifted to a suitable height, the two limiting blocks clamp the pulley to fix the side beam 120.

[0129] According to the photovoltaic bracket 10 provided in the embodiment of the present application, the sliding portion 122 is clamped by providing a limit member 420 installed on the base plate 410 to facilitate locking the side beam 120, which has a simple structure and good stability.

[0130] In some embodiments, as Figure 8 As shown, the limiting structure 400 may further include an adjusting rod 430 .

[0131] The adjusting rod 430 is adjustably mounted on the limiting member 420 and abuts against the sliding portion 122 .

[0132] In this embodiment, the adjusting rod 430 is a screw rod, which is fixed by adjusting the adjusting rod 430 to abut against the roller. At the same time, by rotating the adjusting rod 430, the length of the adjusting rods 430 at both ends passing through the limit piece 420 is adjusted, so that the side beam 120 can be adjusted in height within a certain range.

[0133] In this embodiment, the limiting structure 400 may further include limiting screws, which respectively penetrate the limiting members 420 and the side columns 110 at both ends of the base plate 410 to ensure that the limiting members 420 will not overturn when subjected to force.

[0134] It should be noted that the limiting structure 400 includes two parts, each of which contains a base plate 410, a limiting member 420 and an adjusting rod 430. The upper and lower parts of the limiting structure 400 can be installed on the side column 110 after the side beam 120 is lifted to a suitable height, or they can be pre-connected with the side beam 120 at the bottom of the side column 110, and elastic balls are arranged between the upper and lower parts of the limiting structure 400 and the inner walls on both sides of the side column 110 and between the sliding part 122, so that the limiting structure 400 can be installed on the side column 110 after following the side beam 120 to be lifted to a suitable height.

[0135] According to the photovoltaic support 10 provided in the embodiment of the present application, an adjustable adjustment rod 430 is provided on the limit member 420 to facilitate fixing the side beam 120 and adjusting the height of the side beam 120 within a certain range.

[0136] In some embodiments, as Figure 2 、 Figure 3 and Figure 10 As shown, the photovoltaic support 10 may further include a temporary support frame 500 .

[0137] The temporary support frame 500 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.

[0138] In this embodiment, the temporary support frame 500 is arranged at the bottom of the center column 210. When the component cable 300 is connected to the side beam 120, the middle part of the component cable 300 can be supported on the temporary support frame 500. The temporary support frame 500 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 500 can bear the weight of the component cable 300 and the photovoltaic component 20, ensuring that the component cable 300 can complete the tensioning.

[0139] For example, a groove may be provided above the temporary support frame 500 for supporting the assembly cable 300 .

[0140] According to the photovoltaic bracket 10 provided in the embodiment of the present application, a temporary support frame 500 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 500 can bear the weight of the component cable 300 and the photovoltaic component 20 to assist in the tensioning of the component cable 300.

[0141] In some embodiments, as Figure 10 As shown, the temporary support frame 500 may include a base 510 and a support rod 520 .

[0142] The support rod 520 is mounted on the base 510 .

[0143] The base 510 is suitable for being arranged adjacent to the center column 210 , and the support rods 520 are located on both sides of the center column 210 . The support rods 520 are used to support the component cables 300 when the component cables 300 are installed.

[0144] In this embodiment, the base 510 surrounds the bottom of the center column 210, and the support rod 520 is installed at the upper end of the base 510. The support rod 520 is located on both sides of the center column 210 and has a certain inclination angle. When the component cable 300 is installed, the middle part of the component cable 300 is supported by the support rod 520. Since the support rod 520 has a certain inclination angle, the photovoltaic component 20 is also installed at a certain inclination angle after being installed on the component cable 300, so that the photovoltaic component 20 can better receive light after being lifted.

[0145] According to the photovoltaic bracket 10 provided in the embodiment of the present application, by arranging the support rods 520 on the base 510, and the support rods 520 are located on both sides of the center column 210, the support for the component cable 300 and the photovoltaic component 20 is better and the stability is higher.

[0146] The embodiment of the present application also provides a photovoltaic system 1 .

[0147] like Figures 1-6 As shown, the photovoltaic system 1 includes: a photovoltaic bracket 10 and a photovoltaic component 20.

[0150] In this embodiment, the component rope 300 is installed on the side beam 120 of the photovoltaic bracket 10, and multiple groups of photovoltaic components 20 are installed on the component rope 300. The side beam 120 slides to drive the component rope 300 and multiple groups of photovoltaic components 20 to rise, and then fixed after rising to a suitable height.

[0151] The rotation axes of the two sliding parts 122 of the side beam 120 are not parallel to the length direction of the side beam body 121. After installation, the photovoltaic assembly 20 has a certain tilt angle, which can better receive light, and the photovoltaic system 1 has a higher power generation efficiency.

[0152] According to the photovoltaic system 1 provided in the embodiment of the present application, the installation of the photovoltaic system 1 can be completed by installing the component rope 300 on the side beam 120 of the photovoltaic bracket 10, installing the photovoltaic component 20 on the component rope 300, lifting the component rope 300 and the photovoltaic component 20 and fixing them.
