Description

[0002] With the increasing global energy demand and the growing awareness of environmental protection, renewable energy, especially solar energy, is increasingly valued as a clean and pollution-free energy source. Traditional fixed photovoltaic panel supports can only receive sunlight for a limited period of time during the day, resulting in low photoelectric conversion efficiency. In order to improve the power generation efficiency, large-span flexible photovoltaic support technology has been gradually applied to photovoltaic power generation projects in various complex terrains and environmental conditions.

[0003] Currently, photovoltaic power generation projects are being developed and constructed in large-span ponds, complex geological conditions in mountainous areas, and above sewage collection pools. The common feature of these areas is complex terrain and difficult construction, and traditional fixed photovoltaic supports cannot meet the requirements. The flexible photovoltaic support is characterized by tensioning prestressed steel strands between two supports, fixing photovoltaic panels on the cable, and fixing the support on a rigid foundation. The support is kept stable by cable-stayed and can achieve a large range of span. This design allows photovoltaic panels to be installed on uneven or complex terrain, greatly expanding the application range of photovoltaic power generation.

[0004] However, in practical applications, especially when installing photovoltaic panels on complex terrains such as slopes, the following main problems exist:

[0005] Time-consuming and labor-intensive: Installing photovoltaic panels on slopes requires a large amount of manpower to transport the panels to the mountain, which not only takes a long time but also requires a high labor intensity. Especially in steep terrain or areas with poor transportation, manual transportation becomes more difficult.

[0006] High installation difficulty: The complex terrain on the slope requires consideration of factors such as slope and stability during installation, increasing the complexity and difficulty of installation. For example, the foundation construction of the support, cable laying, etc. all require additional technology and time.

[0007] High cost: Due to the need for a large amount of manpower and special equipment for transportation and installation, the overall cost is high. In addition, complex terrain may require additional materials and equipment to ensure the stability and safety of the structure.

[0008] Reliability issues: Complex terrain may cause the support structure to be unstable, affecting the long-term reliable operation of the system. For example, the stability of the support under strong winds or earthquakes and other natural disasters is an important consideration factor.

[0009] Therefore, a flexible photovoltaic panel support and its installation method are proposed to solve the above problems. SUMMARY

Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0047] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below by combining the figures.

[0048] The flexible photovoltaic panel support provided by the embodiment refers to Figures 1 to 9 , specifically comprises end rods 1, middle rods 2 and main cables 3, two end rods 1 form a group and are located at the ends of the main cables 3, and are used for fixing the main cables 3.

[0049] The middle rods 2 are arranged between the two end rods 1 at the ends and support and reinforce the main cables 3. The end rod top seat 19 at the top of the end rod 1 is provided with a main roller 191 and a power roller 192. The main roller 191 is used for bearing the main cables 3, and the power roller 192 is used for bearing the power cables 31.

[0050] The power cables 31 are provided with detachable clamping sliding members 5. The clamping sliding members 5 are installed on the photovoltaic panel support 62 and are clamped on the power cables 31 through locking members 52. The clamping sliding members 5 also slide and abut against the main cables 3. The photovoltaic panel 4 is dragged on the main cables 3 through the power cables 31 to realize long-distance transportation of the photovoltaic panel 4. After being moved to a predetermined position, the photovoltaic panel 4 can be fixed on the main cables 3 through the clamps 6 and the fixing blocks 61, thereby saving manpower, material resources and time.

[0051] As shown in Figure 1 , the end rod 1 is rotatably connected with the mounting seat 12 installed on the cement pier 13 through the end rod base 11 at the bottom. The rotation direction is consistent with the main cables 3, and the top of the end rod 1 is fixed through the stay cables 17. The tension of the main cables 3 can be adjusted according to the stay cables 17. The top of each end rod 1 is provided with two stay cables 17, and the two stay cables 17 are symmetrically distributed about the main cables 3. The angle between the two stay cables 17 is 5-30 degrees. In the embodiment, the angle between the two stay cables 17 is 10 degrees, which effectively fixes the end rod 1. Two tension rods 15 are arranged between the two end rods 1 at the same end. The two tension rods 15 are crosswise fixed on the top and bottom of the end rod 1. Each tension rod 15 is provided with a tensioner 16 for adjusting the position of the end rod. The top of the two end rods 1 can be additionally provided with a reinforcing rod 14 for reinforcement.

[0052] As shown in Figure 3 , the middle rod 2 is rotatably installed on the mounting seat 12 through the middle rod base 24 at the bottom. The top of the middle rod 2 is provided with a support rod 21 for supporting the main cables 3. The support rod 21 fixes the main cables 3 through the wire fixers 22 at the two ends. The two ends of the support rod 21 are also fixed with the stay cables 17, and the other ends of the stay cables 17 are fixed on the cement pier 13. The two ends of the support rod 21 are also fixed with the inclined braces 23, and the other ends of the inclined braces 23 are installed on the middle rod 2 to reinforce the support rod 21.

[0053] In another embodiment, as shown in Figure 4 , 5As shown, the bottom of the middle pole 2 is fixed to the cement block 13. The top of the middle pole 2, on the middle pole top seat 25, is equipped with an elevation angle rotating seat 26, an elevation angle adjusting rod 262, an azimuth angle rotating seat 27, and an azimuth angle adjusting rod 272. The elevation angle adjusting rod 262 is parallel to the main cable 3, with one end fixed to the elevation angle rotating seat 26. The other end of the elevation angle adjusting rod 262 is connected to one end of the elevation angle actuator 261, and the other end of the elevation angle actuator 261 is connected to the middle pole 2. Two azimuth angle rotating seats 27 are fixed to the elevation angle adjusting rod 262 and enclose the azimuth angle adjusting rod 272. An azimuth angle actuator 271 is installed on the azimuth angle adjusting rod 272, with one end of the azimuth angle actuator 271 installed on the elevation angle adjusting rod 262. Support rods 21 for supporting the main cable 3 are installed at both ends of the azimuth angle adjusting rod 272, and cable fasteners 22 for fixing the main cable 3 are installed at both ends of the support rods 21.

[0054] In this embodiment, both the elevation angle actuator 261 and the azimuth angle actuator 271 are electric cylinders, directly driven by electricity. The elevation angle actuator 261 drives the elevation angle adjustment rod 262 to rotate according to the sun's elevation angle, thereby adjusting the elevation angle of the photovoltaic panel 4 on the main cable 3 to maintain the optimal incident angle. The azimuth angle actuator 271 drives the azimuth angle adjustment rod 272 to rotate according to the sun's azimuth angle, thereby adjusting the horizontal direction of the photovoltaic panel 4 on the main cable 3 to ensure that the photovoltaic panel 4 faces the sun and optimizes the light reception efficiency.

[0055] This application also provides an installation method for a flexible photovoltaic panel bracket.

[0056] Specifically, the following steps are included:

[0057] S1: Installation and pre-fixing of end rod 1

[0058] First, two sets of end rods 1 are installed on the pre-cast concrete piers 13. Each set of end rods 1 consists of two rods, located at both ends of the entire support system. For example... Figure 1 As shown, the top of the end pole 1 is fixed by a guy wire 17, which can be used to tighten or loosen the main cable 3. The angle between the two guy wires 17 is 10 degrees. The other end of the guy wire 17 is fixed to the guy base 18 of the concrete block 13, effectively fixing the end pole 1. The design of the guy wire 17 should ensure that it can withstand the load from the main cable 3 and subsequent installation components. Two tensioning rods 15 are set between the two end poles 1 at the same end. The two tensioning rods 15 are fixed crosswise at the top and bottom of the end pole 1. Each tensioning rod 15 is equipped with a tensioner 16 for adjustment. The top of the two end poles 1 are also reinforced with a reinforcing rod 14.

[0059] S2: Laying the main cable 3

[0060] As shown in Figure 10 Two main cables 3 are laid parallel between the two end poles 1, and the main cables 3 are made of steel strands with appropriate diameters. The two ends of the main cables 3 need to pass around the main rollers 191 set on the top of each end pole 1, so as to ensure smooth operation of the main cables 3 and easy adjustment of tension. The two ends of the main cables 3 can be fixed on the concrete piers 13, but in this case, sufficient length of the main cables 3 needs to be reserved.

[0061] S3: Arrangement of power cables 31

[0062] As shown in Figure 10 Two power cables 31 are erected parallel on the same path, and the two cables also need to pass around the power rollers 192 on the top of the end poles 1. The power cables 31 are used to drive the photovoltaic panels 4 to move along the main cables 3 by connecting to the winches.

[0063] S4: Assembly of photovoltaic panels 4

[0064] As shown in Figure 7 Clamping slides 5 are installed on the four corners of the bottom of each photovoltaic panel 4, and the slides are firmly clamped on the power cables 31 by locking members 52; at the same time, the sliding pieces 51 or pulleys at the bottom of the clamping slides 5 are placed on the main cables 3, so that the photovoltaic panels 4 can move smoothly along the main cables 3.

[0065] S5: Transportation of photovoltaic panels 4

[0066] As shown in Figure 11 A group of photovoltaic panels 4 are connected in series, and then one end of the power cable 31 is connected to the winch. After starting the winch, it pulls the power cable 31, thereby driving the entire group of photovoltaic panels 4 to move along the main cable 3 to the predetermined position.

[0067] S6: Positioning and fixing of photovoltaic panels 4

[0068] As shown in Figure 11 When the photovoltaic panels 4 reach the designated position, a middle pole 2 is installed at the interval between each group of photovoltaic panels 4. Then, the main cable 3 is passed through the cable fasteners 22 at both ends of the support pole 21, as shown in Figure 3 or Figure 4 The clamping slides 5 are removed and replaced with the clamps 6 and the fixing blocks 61, as shown in Figure 8 The fixing blocks 61 are fixed at the bottom of the photovoltaic panel supports 62, and the clamps 6 are wrapped around the main cables 3 and locked by the fixing blocks 61.

[0069] S7: Forming a column of photovoltaic panels 4

[0070] According to step S6, a plurality of groups of photovoltaic panels 4 and middle poles 2 are installed, as shown in Figure 12As shown. After the traction and fixing of multiple photovoltaic panels 4 are completed, the main cable 3 is further fixed using the cable fastener 22 at the top of the central pole 2. At this point, the multiple photovoltaic panels 4, together with the end poles 1 at both ends and the central pole 2 in the middle, form a complete longitudinal row of photovoltaic panels 4. The power cable 31 can be removed as needed, and the main cable 3 can be adjusted appropriately.

[0071] S8: 4-array connection of photovoltaic panels

[0072] like Figure 9 As shown, the final step is to use connecting rods 28 to connect the middle rods 2 between adjacent columns, thereby enhancing the stability of the entire photovoltaic panel support system 62 and finally completing the construction of the multi-column photovoltaic panel support system 62. After installation, the photovoltaic panels 4 are electrically connected.

[0073] In addition, to optimize the angle at which the photovoltaic panel 4 receives sunlight, the central pole 2 adopts the following... Figure 4 , 5 The adjustment system shown is equipped with an altitude angle actuator 261 and an azimuth angle actuator 271 on the central pole 2, both of which are electric cylinders and electrically connected to sensors and a controller. This system can monitor the sun's position changes in real time and automatically calculate the optimal angle adjustment scheme, then instruct the actuators to execute the corresponding angle adjustment actions. In this way, not only can the photovoltaic panel 4 always face the sun, but the overall power generation efficiency can also be effectively improved.

[0074] The elevation angle actuator 261 controls the vertical angle adjustment of the photovoltaic panel 4, while the azimuth angle actuator 271 controls the horizontal angle adjustment. The two sets of photovoltaic panels 4 before and after the center pole 2 adjust the elevation angle of the photovoltaic panels 4 on the main cable 3 through the elevation angle actuator 261 on the center pole 2; the azimuth angle actuator 271 adjusts the horizontal angle of the photovoltaic panels 4 on the main cable 3.
