Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a flexible photovoltaic panel bracket and a mounting method thereof. Background Art

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

[0003] At present, the development and construction of photovoltaic power generation projects have been gradually carried out in areas such as large-span ponds, mountainous areas with complex geological conditions, and above sewage collection pools. The common characteristics of these areas are complex terrain and difficult construction, and traditional fixed photovoltaic brackets are difficult to meet the requirements. The characteristics of flexible photovoltaic brackets are that prestressed steel strands are tensioned between two brackets, photovoltaic panels are fixed on the cables, and brackets are fixed on a rigid foundation. The brackets are kept stable by diagonal tension and can achieve a wide range of spans. This design enables 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 hillsides, there are the following main problems:

[0005] Time-consuming and labor-intensive: Installing photovoltaic panels on a hillside requires a large amount of manpower to carry the photovoltaic panels to the mountain, which is not only time-consuming but also labor-intensive. Especially in areas with steep terrain or inconvenient transportation, manual transportation becomes more difficult.

[0006] High installation difficulty: The terrain on the hillside is complex, and factors such as slope and stability need to be considered during the installation process, which increases the complexity and difficulty of installation. For example, the foundation construction of the bracket and the laying of cables require additional technology and time.

[0007] High cost: The overall cost is high due to the need for a lot of manpower and special equipment for handling and installation. In addition, complex terrain may also 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 natural disasters such as strong winds or earthquakes is an important consideration.

[0009] To this end, a flexible photovoltaic panel bracket and an installation method thereof are proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0048] This embodiment provides a flexible photovoltaic panel bracket, referring to Figures 1 to 9 , specifically comprising an end rod 1, a middle rod 2, and a main cable 3, wherein two end rods 1 form a group and are located at the end of the main cable 3, and are used to fix the main cable 3;

[0049] The middle pole 2 is provided with a plurality of end poles 1 distributed between the end poles 1 at both ends to support and reinforce the main cable 3. The end pole top seat 19 at the top of the end pole 1 is provided with a main roller 191 and a power roller 192. The main roller 191 is used to carry the main cable 3, and the power roller 192 is used to carry the power cable 31.

[0050] A detachable clamping slide 5 is installed on the power cable 31, and the clamping slide 5 is installed on the photovoltaic panel bracket 62 and clamped on the power cable 31 through the locking member 52. The clamping slide 5 also slides against the main cable 3. The photovoltaic panel 4 is pulled by the power cable 31 to move on the main cable 3, so that the photovoltaic panel 4 can be transported over a long distance. After moving to a predetermined position, it can be fixed on the main cable 3 through the clamp 6 and the fixing block 61, saving manpower, material resources and time.

[0051] like Figure 1 As shown, the end rod 1 is rotatably connected to the mounting seat 12 installed on the cement pier 13 through the end rod base 11 at the bottom, and the rotation direction is consistent with the main cable 3. The top of the end rod 1 is fixed by the inclined strands 17, and the main cable 3 can be tightened or loosened according to the inclined strands 17. Two inclined strands 17 are arranged on the top of each end rod 1, and the two inclined strands 17 are symmetrically distributed with the main cable 3. The angle between the two inclined strands 17 is 5 degrees to 30 degrees. In this embodiment, the angle between the two inclined strands 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 cross-fixed at the top and bottom of the end rod 1. A tensioner 16 is arranged on each tension rod 15 to adjust the position of the end rod. Reinforcement rods 14 can also be installed on the top of the two end rods 1 for reinforcement.

[0052] like Figure 3 As shown, the middle pole 2 is rotatably mounted on the mounting seat 12 through the middle pole base 24 at the bottom, and a support rod 21 for supporting the main cable 3 is arranged on the top of the middle pole 2. The support rod 21 fixes the main cable 3 through the wire fixers 22 at both ends, and the two ends of the support rod 21 are also fixed with oblique stranded wires 17, and the other end of the oblique stranded wire 17 is fixed on the cement pier 13; the two ends of the support rod 21 are also fixed with oblique braces 23, and the other end of the oblique brace 23 is mounted on the middle pole 2 to reinforce the support rod 21.

[0053] In another embodiment, if Figure 4 , 5As shown, the bottom of the middle pole 2 is fixed on the cement pier 13, and the middle pole top seat 25 at the top of the middle pole 2 is provided 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 and one end is fixed on the elevation angle rotating seat 26, and the other end of the elevation angle adjusting rod 262 is connected to one end of the elevation angle driver 261, and the other end of the elevation angle driver 261 is connected to the middle pole 2. The azimuth angle rotating seat 27 is fixed on the elevation angle adjusting rod 262. The azimuth angle rotating seat 27 is provided with two and wraps the azimuth angle adjusting rods 272, and the azimuth angle driver 271 is installed on the azimuth angle adjusting rod 272. One end of the azimuth angle driver 271 is installed on the elevation angle adjusting rod 262. Support rods 21 supporting the main cable 3 are installed at both ends of the azimuth angle adjusting rod 272, and cable fixers 22 fixing the main cable 3 are arranged at both ends of the support rod 21.

[0054] In this embodiment, both the elevation angle driver 261 and the azimuth angle driver 271 are electric cylinders, which are directly driven by electricity. The elevation angle driver 261 drives the elevation angle adjustment rod 262 to rotate according to the elevation angle of the sun, thereby driving the photovoltaic panel 4 on the main cable 3 to adjust the elevation angle direction to maintain the best incident angle; the azimuth angle driver 271 drives the azimuth angle adjustment rod 272 to rotate according to the azimuth angle of the sun, thereby driving the photovoltaic panel 4 on the main cable 3 to adjust the horizontal direction, ensuring that the photovoltaic panel 4 faces the sun and optimizes the light receiving efficiency.

[0055] The present application also provides a method for installing a flexible photovoltaic panel bracket.

[0056] The specific steps include:

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

[0058] First, two sets of end rods 1 are installed on the pre-cast concrete pier 13. Each set of end rods 1 consists of two rods, which are located at the two ends of the entire support system. Figure 1 As shown, the top of the end rod 1 is fixed by an oblique strand 17, and the main cable 3 can be tightened or loosened according to the oblique strand 17. The angle between the two oblique strands 17 is 10 degrees. The other end of the oblique strand 17 is fixed on the oblique base 18 of the cement pier 13, which effectively fixes the end rod 1. The design of the oblique strand 17 should ensure that it can withstand the load from the main cable 3 and subsequent installation components. Two tension rods 15 are arranged between the two end rods 1 at the same end. The two tension rods 15 are cross-fixed at the top and bottom of the end rod 1. A tensioner 16 is arranged on each tension rod 15 for adjustment. A reinforcing rod 14 is also installed on the top of the two end rods 1 for reinforcement.

[0059] S2: Laying down the main cable 3

[0060] like Fig.10 As shown, two main cables 3 are laid in parallel between the two end rods 1. The main cables 3 are made of steel strands with appropriate diameters. Both ends of the main cables 3 need to pass over the main rollers 191 provided on the top of each end rod 1 to ensure that the main cables 3 run smoothly and are easy to adjust the tension. Both ends of the main cables 3 can be fixed on the cement pier 13, but at this time, a sufficient length of the main cables 3 needs to be reserved.

[0061] S3: Power cable 31 layout

[0062] like Fig.10 As shown, two power cables 31 are set up in parallel on the same path, and these two cables also need to pass around the power roller 192 at the top of the end rod 1. The function of the power cable 31 is to drive the photovoltaic panel 4 to move along the main cable 3 by connecting the winch.

[0063] S4: Photovoltaic panel 4 assembly

[0064] like Figure 7 As shown, clamping slides 5 are installed at the four corners of the bottom of each photovoltaic panel 4, and these slides are firmly clamped on the power cable 31 through locking members 52; at the same time, the sliding sheet 51 or pulley at the bottom of the clamping slide 5 should be placed on the main cable 3 so that the photovoltaic panel 4 can move smoothly along the main cable 3.

[0065] S5: Photovoltaic Panel 4 Transportation

[0066] like Fig.11 As shown, 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 the winch is started, it pulls the power cable 31, thereby driving the entire group of photovoltaic panels 4 to advance to a predetermined position along the main cable 3.

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

[0068] like Fig.11 As shown in FIG. 1 , when the photovoltaic panels 4 reach the designated position, the middle pole 2 is installed at the interval between each group of photovoltaic panels 4. Next, the main cable 3 is passed through the cable holders 22 at both ends of the support pole 21, as shown in FIG. Figure 3 or Figure 4 Remove the clamping slide 5 and replace it with a clamp 6 and a fixing block 61, as shown. Figure 8 The fixing block 61 is fixed to the bottom of the photovoltaic panel support 62 , and the clamp 6 surrounds the main cable 3 and is locked by the fixing block 61 .

[0069] S7: Forming 4 vertical rows of photovoltaic panels

[0070] According to step S6, multiple groups of photovoltaic panels 4 and the middle pole 2 are installed. Fig.12As shown. After the pulling and fixing of the multiple photovoltaic panels 4 are completed, the main cable 3 is further fixed by the cable fixer 22 on the top of the middle pole 2. At this time, the multiple photovoltaic panels 4, the end poles 1 at both ends and the middle pole 2 in the middle together form a complete vertical column 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 photovoltaic arrays connected

[0072] like Fig. 9 As shown, the last step is to use the connecting rod 28 to connect the middle poles 2 between two adjacent columns to enhance the stability of the entire photovoltaic panel support 62 system and finally complete the construction of the multi-column photovoltaic panel support 62. After installation, the photovoltaic panels 4 are electrically connected.

[0073] In addition, in order to optimize the angle at which the photovoltaic panel 4 receives light, the middle pole 2 is Figure 4 , 5 The adjustment system shown. The middle pole 2 is equipped with an altitude angle driver 261 and an azimuth angle driver 271, both of which use electric cylinders, which are electrically connected to the sensor and the controller. This system can monitor the position changes of the sun in real time, automatically calculate the best angle adjustment plan, and then instruct the driver to perform the corresponding angle adjustment action. In this way, it can not only ensure that the photovoltaic panel 4 is always facing the sun, but also effectively improve the overall power generation efficiency.

[0074] The elevation angle driver 261 is responsible for controlling the vertical angle adjustment of the photovoltaic panels 4, while the azimuth angle driver 271 is responsible for the horizontal angle adjustment. The two groups of photovoltaic panels 4 in front and behind the middle pole 2 drive the photovoltaic panels 4 on the main cable 3 to adjust the elevation angle through the elevation angle driver 261 on the middle pole 2; the azimuth angle driver 271 drives the photovoltaic panels 4 on the main cable 3 to adjust the horizontal direction.
