[0055] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as limiting the present application.

[0056] The principle of the photovoltaic support 10 proposed in the present application is described in detail below:

[0057] In the related art, the installation process of the photovoltaic support is as follows: after the edge column and the middle column are installed, the assembly cable is tensioned and the photovoltaic assembly is installed on the assembly cable. The installation of the photovoltaic assembly is a high-altitude operation, which has low installation efficiency, high cost and great risk.

[0058] To solve the technical problem, the present application provides a photovoltaic support 10, which is described below with reference to Figures 1-9 The photovoltaic support 10 according to the embodiments of the present application is described below.

[0059] As shown in Figures 1-4 , the photovoltaic support 10 of the embodiments of the present application comprises: an edge support structure 100, a middle support structure 200 and an assembly cable 300.

[0060] As shown in Figures 1-5 , the edge support structure 100 comprises an edge column 110 and a rolling support mechanism 120.

[0061] The edge column 110 can be made of materials such as aluminum alloy, stainless steel, hot-dip galvanized steel or composite material, which is not specifically limited in the present embodiment.

[0062] The cross section of the edge column 110 can be circular, rectangular, triangular or polygonal, and can also be customized according to specific installation requirements and design requirements.

[0063] The edge column 110 is fixed to the ground, which can be fixed to the ground by pouring concrete, using anchor bolts, chemical anchoring agents or other mechanical anchoring systems, etc. In the present embodiment, the edge column 110 can be fixed to the ground by pile foundation, which has good stability.

[0064] For example, the edge support structure 100 can comprise a connecting beam 150 and two edge columns 110, the connecting beam 150 being connected between the two edge columns 110, the connecting beam 150 bearing part of the force of the edge column 110 to improve stability. As shown in Figure 5 , the rolling support mechanism 120 is installed at the top of the edge column 110, which is used to roll and support the assembly cable 300.

[0065] As shown in Figures 1-4 and Figure 7 , the middle support structure 200 comprises a middle column 210 and a middle beam 220.

[0066] The middle column 210 can be made of aluminum alloy, stainless steel, hot-dip galvanized steel or composite material, and the material of the middle column 210 can be the same as or different from that of the side column 110.

[0067] In some embodiments, the installation height requirement of the photovoltaic module 20 is high, and the middle column 210 can be designed as a multi-section middle column 210 structure, which is nested layer by layer and can be moved relative to each other to adjust the height of the middle column 210. After adjusting to the designed height, it is fixed and limited.

[0068] In this embodiment, the middle column 210 is installed on the pipe pile.

[0069] The middle beam 220 is installed on the top of the middle column 210.

[0070] In this embodiment, after the middle beam 220 is installed on the top of the middle column 210, the length direction of the middle beam 220 forms a certain angle with the ground, so that the photovoltaic module 20 can better receive light.

[0071] The assembly cable 300 is used to support the rolling support mechanism 120 at both ends of the photovoltaic support 10, and the assembly cable 300 is connected to the middle beam 220 and the side column 110.

[0072] In this embodiment, the middle beam 220 is provided with a steel wire rope clamp mounting hole, which is used to install the steel wire rope clamp of the assembly cable 300 after the assembly cable 300 is lifted.

[0073] In the related art, the installation process of the photovoltaic support is that after the side column and the middle column are installed, the assembly cable is tensioned and the photovoltaic module is installed on the assembly cable. The photovoltaic module has certain requirements on the installation height. The installation of the photovoltaic module is a high-altitude operation, which has great difficulty, low efficiency, high risk, and high cost of lifting and installing the heavy photovoltaic module to a high place.

[0074] In this embodiment, after the side support structure 100 and the middle support structure 200 of the photovoltaic support 10 are installed, the two ends of the assembly cable 300 are supported by the rolling support mechanism 120. The assembly cable 300 has no initial pre-tension and is in a relaxed state. The middle part of the assembly cable 300 is in a low position. The photovoltaic module 20 is installed in the low position. The installation difficulty is small. The assembly cable 300 is pulled on one side of the side column 110 to lift the photovoltaic module 20. After being lifted to the preset height, the assembly cable 300 is connected to the middle beam 220 and the side column 110, the installation of the photovoltaic module 20 is completed, the installation efficiency is high, the cost is low, and the safety is high. The tensioning of the assembly cable 300 is completed synchronously, and the installation steps are less.

[0075] The photovoltaic support 10 of the embodiment supports the component cable 300 through the rolling support mechanism 120 in addition to the support of the component cable 300 at the anchoring position of the component cable 300 after the photovoltaic module 20 is installed and used, so that the stress on the component cable 300 is more reasonable and the component cable 300 is less likely to break, and the stability of the component cable 300 is better in the case of strong wind and the like. In addition, the rolling support mechanism 120 has small resistance and good support when the tension of the component cable 300 is adjusted again.

[0076] It should be noted that the rolling support mechanism 120 can continue to support the component cable 300 after the photovoltaic module 20 is installed, or the rolling support mechanism 120 can be removed to assist other photovoltaic supports 10 to install the photovoltaic module 20.

[0077] According to the photovoltaic support 10 provided in the embodiments, the rolling support mechanism 120 is arranged on the edge column 110 at both ends of the photovoltaic support 10, so that the photovoltaic module 20 can be installed on the component cable 300 at a low position when the component cable 300 is supported by the rolling support mechanism 120, and the installation difficulty is small, the installation efficiency is high, the cost is low, and the safety is high. In addition, the rolling support mechanism 120 has good support on the component cable 300 during later use, and the component cable 300 is easy to adjust and tension, and the photovoltaic support 10 has good stability.

[0078] In some embodiments, the rolling support mechanism 120 can include a rolling part 121.

[0079] As shown in Figure 6 The rolling part 121 can be provided in multiple numbers and arranged at the top of the edge column 110 at intervals.

[0080] In the embodiment, the rolling parts 121 are arranged at the top of the edge column 110 at intervals, and the ends of the component cable 300 are supported by the rolling parts 121 after the edge support structure 100 and the middle support structure 200 are installed. The component cable 300 has no initial pre-tension and is in a relaxed state. When the component cable 300 is pulled on one side of the edge column 110, the force acting on the rolling parts 121 changes in size and direction, and the stress on the component cable 300 is more reasonable and less likely to break. The rolling parts 121 are provided in multiple numbers to make the pulling process labor-saving and stable. In the case of strong wind and the like, the stability of the component cable 300 is better, and the tension of the component cable 300 needs to be adjusted in the later period. When tensioned again, the rolling support mechanism 120 has small resistance, and the support and stability of the rolling parts 121 are better.

[0081] According to the photovoltaic support 10 provided in the embodiment of the present application, the plurality of rolling parts 121 are arranged at the top of the edge column 110, the support of the rolling support mechanism 120 is better, the stability during the traction lifting is better, and the tensioning and adjustment of the module cable 300 in the later stage are easier.

[0082] In some embodiments, the rotation axes of the rolling parts 121 can be parallel.

[0083] As shown in the figure, the height of the rotation axis of the rolling part 121 gradually increases in the direction away from the middle part of the module cable 300. Figure 6

[0084] In the embodiment, the rolling support mechanism 120 can include a first rolling part 121 and a second rolling part 121, the rotation axes of the first rolling part 121 and the second rolling part 121 are parallel, the heights of the rotation axes of the first rolling part 121 and the second rolling part 121 are inconsistent, the first rolling part 121 and the second rolling part 121 are arranged in the direction away from the middle part of the module cable 300, the height of the rotation axis of the second rolling part 121 is higher than that of the first rolling part 121, the edge support structure 100 and the middle support structure 200 are installed, the module cable 300 is supported by the first rolling part 121 and the second rolling part 121, the module cable 300 has no initial pre-tension and is in a relaxed state, when the module cable 300 is pulled on one side of the edge column 110, the module cable 300 slides on the first rolling part 121 and the second rolling part 121, the rotation axis of the first rolling part 121 is lower than that of the second rolling part 121, and the first rolling part 121 is closer to the edge of the top of the edge column 110, during the process that the module cable 300 is lifted from the low position to the preset height, the module cable 300 will not interfere with the edge column 110, and the support and stability are better.

[0085] According to the photovoltaic support 10 provided in the embodiment of the present application, the rolling parts 121 with different heights of rotation axes are arranged, during the traction lifting of the module cable 300, the interference between the module cable 300 and the edge column 110 is avoided, and the support and stability are better.

[0086] In some embodiments, the top of the edge column 110 can be provided with an ear 130.

[0087] As shown in the figure, the rolling part 121 is rolling assembled in the ear 130. Figure 6

[0088] In the embodiment, the rolling part 121 can be a pulley, the ear 130 can include two oppositely arranged side plates, the side plates are provided with through holes, a rotating shaft penetrates through the through holes, the rolling part 121 is rolling assembled in the rotating shaft, and the height of the rotation axis of the rotating shaft can be set according to actual use requirements.

[0089] ​​It can be understood that the rolling part 121 can also prevent the protective sleeve of the assembly cable 300 from being abraded during traction.

[0090] The rolling part 121 can be made of aluminum alloy, stainless steel, carbon steel, rubber, or composite material, and is not specifically limited in the embodiment.

[0091] According to the photovoltaic support 10 provided in the embodiment of the present application, the lug 130 is arranged at the top of the side column 110, and the rolling part 121 is rollingly assembled in the lug 130, so that the rolling part 121 does not interfere with the side column 110 when the assembly cable 300 is lifted.

[0092] In some embodiments, as shown in Figure 6 The side column 110 can be provided with a mounting part 140 at the top.

[0093] The mounting part 140 is located on one side of the rolling support mechanism 120 away from the middle of the assembly cable 300, and the assembly cable 300 is connected to the side column 110 through the mounting part 140.

[0094] In the embodiment, the mounting part 140 can be a through hole, and the assembly cable 300 passes through the mounting part 140. After the photovoltaic module 20 is lifted to a predetermined height, the assembly cable 300 is anchored at the mounting part 140 by an anchor.

[0095] According to the photovoltaic support 10 provided in the embodiment of the present application, the mounting part 140 is arranged at the top of the side column 110, so as to support and fix the assembly cable 300.

[0096] In some embodiments, the photovoltaic support 10 can further include a temporary support frame 400.

[0097] As shown in Figures 1-4 and Figure 7 The temporary support frame 400 is adapted to be arranged adjacent to the middle column 210, and the temporary support frame 400 is used to support the assembly cable 300 when the assembly cable 300 is installed.

[0098] In the embodiment, the temporary support frame 400 is arranged at the bottom of the middle column 210. When the assembly cable 300 is supported by the rolling support mechanism 120, the middle of the assembly cable 300 can be supported by the temporary support frame 400. The temporary support frame 400 can ensure that the assembly cable 300 has a certain initial height during installation, so as to provide an operation space for the installation of the photovoltaic module 20. Meanwhile, the temporary support frame 400 can bear the weight of the assembly cable 300 and the photovoltaic module 20, so as to ensure that the assembly cable 300 can be tensioned.

[0099] For example, a groove can be arranged above the temporary support frame 400, which is used to support the assembly cable 300.

[0100] According to the photovoltaic support 10 provided in the embodiment of the present application, the temporary support frame 400 is arranged near the middle column 210 to provide an operation space for the installation of the photovoltaic module 20 when the assembly cable 300 is installed, and the temporary support frame 400 can bear the weight of the assembly cable 300 and the photovoltaic module 20 to help tension the assembly cable 300.

[0103] The support rod 420 can be installed on the base 410 by bolt connection, welding or clamping, etc., which is not specifically limited in the embodiment.

[0104] In some embodiments, the support rod 420 and the base 410 can also be integrally formed.

[0105] The base 410 is suitable to be arranged near the middle column 210, and the support rod 420 is located on both sides of the middle column 210, and the support rod 420 is used to support the assembly cable 300 when the assembly cable 300 is installed.

[0129] According to the construction method provided in the embodiment of the present application, by setting a rolling support mechanism 120 on the side columns 110 at both ends of the photovoltaic bracket 10, when the component rope 300 is supported on the rolling support mechanism 120, the photovoltaic component 20 can be installed at a low position on the component rope 300, the installation difficulty is relatively small, the installation efficiency is relatively high, and the photovoltaic component 20 is lifted by traction equipment and lifting equipment, the cost is relatively low, and the safety is relatively high.

[0130] In some embodiments, as Figure 9 As shown, the construction method may include: step 531 and step 571.

[0131] In the case where the photovoltaic support 10 further includes a temporary support frame 400, step 530, installing the component cable 300 and supporting the component cable 300 on the rolling support mechanism 120, with the middle portion of the component cable 300 being lower than the height of the rolling support mechanism 120, may include:

[0132] like Figure 2 As shown, in step 531 , the component cable 300 is installed and supported on the rolling support mechanism 120 , with the middle portion of the component cable 300 lower than the rolling support mechanism 120 , and the middle portion of the component cable 300 is supported on the temporary support frame 400 .

[0133] In this embodiment, the temporary support frame 400 is arranged at the bottom of the center column 210. When the component cable 300 is supported on the rolling support mechanism 120, the middle part of the component cable 300 is lower than the rolling support mechanism 120, and the middle part of the component cable 300 can be supported on the temporary support frame 400. The temporary support frame 400 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 400 can bear the weight of the component cable 300 and the photovoltaic component 20, ensuring that the component cable 300 can complete the tensioning.

[0134] Step 570, pulling the assembly cable 300 outside the edge support structure 100 to lift the photovoltaic assembly 20 may include:

[0135] Step 571 : Pull the assembly rope 300 outside the edge support structure 100 and lift the temporary support frame 400 to elevate the photovoltaic assembly 20 .

[0136] like Figure 3 As shown, in this embodiment, when a traction device is used to pull the component rope 300 on the outside of the side column 110 of the side support structure 100, the temporary support frame 400 at the lower part of the middle column 210 can be synchronously assisted in lifting by a lifting device, so that the photovoltaic components 20 on the component rope 300 are synchronously raised to a preset height, avoiding damage to the component rope 300 and the photovoltaic component 20 due to the component rope 300 being too long and only being pulled from the outside of the side column 110.

[0137] It is understandable that the lifting equipment can be a forklift or other equipment. After the component rope 300 is lifted to a preset height, the middle part of the component rope 300 is installed on the middle beam 220 of the middle support structure 200. After the installation is completed, the temporary support frame 400 is removed and the photovoltaic component 20 is installed.

[0138] According to the construction method provided in the embodiment of the present application, a temporary support frame 400 is set near the center column 210. When the component cable 300 is supported on the rolling support mechanism 120, the middle part of the component cable 300 is supported on the temporary support frame 400, providing an operating space for the installation of the photovoltaic component 20. The component cable 300 is pulled outside the side support structure 100, and the temporary support frame 400 is lifted synchronously to lift the photovoltaic component 20, which has high installation efficiency and good stability.
