Description

Technical Field

[0001] This invention relates to the field of photovoltaic modules, and more particularly to a method for arranging photovoltaic modules. Background Technology

[0002] Agricultural photovoltaic industry is an information technology industry that organically combines photovoltaic industry and modern agriculture, representing a new model of compatible coexistence and coordinated development between photovoltaics and agriculture. Photovoltaic agricultural greenhouse and park projects refer to integrated photovoltaic power generation with agricultural production, prioritizing agriculture while simultaneously meeting the basic requirements of both photovoltaic power generation and agricultural production. This achieves the rational and effective utilization of solar resources, realizing a modern agricultural technology complex that is land-saving, energy-efficient, and highly effective. The land use for photovoltaic agricultural greenhouse and park projects should include three parts: agricultural greenhouse land, photovoltaic land, and public facility land. The overall layout of the project should ensure that photovoltaic power generation and crops do not compete for sunlight, and that the maximum installed capacity of photovoltaic power generation equipment is available while meeting the sunlight requirements for agricultural production.

[0003] Related applications have already emerged, such as the Chinese patent CN220255228U, which discloses a type of vegetable greenhouse combining an arched photovoltaic support structure. This greenhouse includes: a photovoltaic support structure, with several photovoltaic support structures evenly spaced; a supporting frame, with several supporting frames evenly spaced between adjacent photovoltaic support structures, the supporting frames being detachably connected to the photovoltaic support structures via connecting components; a plastic film covering the supporting frame; an insect-proof net, installed on the photovoltaic support structures, the insect-proof net and the plastic film working together to form a planting space; and several sets of photovoltaic panels, each set positioned at the top of the photovoltaic support structure, with gaps between adjacent photovoltaic panels. By adjusting the distance and height of the photovoltaic support structures, the expected lighting requirements inside the greenhouse can be met, realizing the dual attributes of power generation above the photovoltaic vegetable greenhouse and planting below.

[0004] However, during application, when facing terrain with significant undulations and large elevation differences, it is necessary to avoid slopes, resulting in low land utilization. Summary of the Invention

[0005] In order to adapt to uneven ground, increase the area of ​​photovoltaic panels laid on the ground, and improve land utilization, this invention provides a method for arranging photovoltaic modules.

[0006] This invention provides a method for arranging photovoltaic modules, employing the following technical solution:

[0007] A method for arranging photovoltaic modules includes the following steps:

[0008] Calculate the area of ​​shadow cast by height difference that can be eliminated by different spacing of photovoltaic panels.

[0009] Based on the actual terrain, stepped intervals are divided according to the elevation difference.

[0010] Pipe piles are installed on the ground, and brackets are installed at the end of the pipe piles that protrude from the ground. Photovoltaic panels are then installed on the brackets.

[0011] The photovoltaic panels are oriented to follow the terrain.

[0012] In one specific feasible implementation, the support structure consists of three rows of supports, such that the spacing between the pipe piles is greater than or equal to 5m.

[0013] In one specific feasible implementation, the spacing between the supports is 100-150mm, and the spacing between the photovoltaic panels is 200-250mm.

[0014] In one specific feasible implementation, the pipe pile includes a pile body and a pile tip, with the pile tip located at the bottom end of the pile body. The pile body has multiple sliding holes, and each sliding hole is equipped with a nozzle.

[0015] In one specific implementation scheme, the pile tip includes a connecting plate and a digging plate. The connecting plate is disposed on the end face of the pile body, and the digging plate is disposed on the side of the connecting plate opposite to the pile body. An installation hole is provided on the circumferential surface of the connecting plate, and a nozzle is disposed in the installation hole.

[0016] In one specific feasible implementation, after the pipe pile is inserted into the ground, grout is injected into the soil layer around the pile through nozzles and sprayers to form a support platform.

[0017] In one specific implementation scheme, a connecting block is provided at one end of the nozzle facing the pile body, the top surface of the connecting block is inclined, an abutment post is inserted into the pile body, and the bottom end of the abutment post is provided with an arc transition.

[0018] When the connecting post is inserted into the pile body, the arc transition of the connecting post abuts against the top surface of the first connecting block, pushing the nozzle to slide out of the pile body.

[0019] In one specific feasible implementation, a grouting hole communicating with a sliding hole is opened on the pile body. The grouting hole is connected to a nozzle. The grouting hole extends along the axial direction of the pile body. Multiple nozzles are arranged at intervals along the axial direction of the pile body, and each nozzle has a through-hole.

[0020] Normally, the connecting hole and the grouting hole are not connected. When the abutment column is inserted into the pile body, it pushes the nozzle to slide out of the pile body, so that the connecting hole on the nozzle and the grouting hole are connected.

[0021] In one specific feasible implementation, there is a gap between the abutment column and the inner wall of the pile body, and grouting is performed into the gap between the abutment column and the pile body.

[0022] In one specific feasible implementation, a cap is provided on the top surface of the pile body, which seals the opening in the gap between the abutment column and the pile body, and a grouting port is provided on the cap.

[0023] In one specific feasible implementation, a clearance hole is provided through the connecting plate, and the axis of the clearance hole is on the same straight line as the axis of the pile.

[0024] In one specific feasible implementation, a grouting hole is provided on the abutment column, the axis of the grouting hole is in the same straight line as the axis of the pile body, and a grouting pipe communicating with the grouting hole is provided on the side of the abutment column facing the connecting plate.

[0025] After the connecting column is inserted into the pile body, the grouting pipe is inserted into the relief hole of the connecting plate. Grouting is performed on the soil layer on the side of the connecting plate away from the pile body by injecting grout into the grouting hole.

[0026] In a specific feasible implementation plan, before grouting, soil samples from the same depth layer on site are obtained, grouting simulation is performed, and grouting pressure and grouting volume are calculated.

[0027] In one specific feasible implementation, the photovoltaic panels are arranged parallel to or nearly parallel to the high-voltage transmission line.

[0028] In summary, the present invention has at least one of the following beneficial technical effects:

[0029] 1. By adjusting the spacing between photovoltaic panels and constructing stepped intervals on the slope, more photovoltaic panels can be installed per unit area, thus improving land utilization.

[0030] 2. By increasing the spacing between the pipe piles and using a three-row support structure, the amount of photovoltaic pipe pile foundation used is reduced, which can lower construction costs. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-11 The present invention will be described in further detail below.

[0044] Example 1:

[0045] The photovoltaic module layout method includes the following steps:

[0046] S100, photovoltaic panel layout design.

[0047] Calculate the shaded area caused by the height difference between photovoltaic panels in the same row, and then calculate the spacing between the photovoltaic panels in the same row. Calculate the shaded area caused by the photovoltaic panels at the top of the slope, and set stepped spacing zones on the slope surface.

[0048] Reference Figure 1 and Figure 2 The pipe piles used for the mounting brackets of photovoltaic panels are prestressed pipe piles with a diameter of 300-400mm. The mounting brackets are arranged in three rows instead of the traditional two rows, thereby reducing the amount of pipe piles used, saving construction costs, and saving land for pipe pile foundations.

[0049] Reference Figure 3The purlins of the mounting bracket support the photovoltaic panels. To accommodate the installation space of the transformer blocks used to fix the photovoltaic panels and to allow for appropriate redundancy, the length of each purlin is 100mm longer than the length of the photovoltaic panel. To eliminate shading caused by height differences between photovoltaic panels in the same row during installation, an adjustment gap is set, typically 300mm according to an empirical formula. The spacing between photovoltaic panels = adjustment gap + length of purlins extending beyond the photovoltaic panels at both ends = 200 + 300 = 500mm.

[0050] Reference Figure 4 To minimize the spacing between photovoltaic panels and ensure that shadows cast by height differences between panels do not affect their operation, the length of the purlins extending beyond the panels was shortened to 50mm. Through actual measurement and calculation, the spacing was further reduced to 150mm, resulting in a total spacing of 250mm between the panels. By shortening the distance between the panels, more photovoltaic panels can be installed per unit area of ​​land, improving land utilization and the photovoltaic conversion efficiency.

[0051] The terrain of the area where the photovoltaic panels will be installed is surveyed, slopes are identified, and slope parameters are measured. Based on the calculated spacing between the photovoltaic panels, the amount of shading that can be eliminated at that spacing is calculated, and stepped spacing zones are established on the slope. For ease of understanding, the following example provides further illustration:

[0052] The slope has a vertical drop of 600mm. Originally, the design required a 750mm spacing between the two sets of photovoltaic panels to avoid the slope. Calculations showed that a 250mm spacing between the photovoltaic panels could eliminate shading caused by the 200mm vertical drop. This means that a spacing zone is constructed at a 200mm vertical drop and a 250mm horizontal distance from the top of the slope, and photovoltaic panels are installed in this zone. The next set of photovoltaic panels is installed in the same manner, thus reducing the spacing between the panels on the slope, further increasing the number of photovoltaic panels installed per unit area of ​​land, and further improving land utilization.

[0053] Reference Figure 5 and Figure 6Typically, photovoltaic (PV) panels are installed at a 0° azimuth angle, meaning the effective surface of the panel faces due south. However, during installation, it's necessary to avoid high-voltage power lines, and different terrain conditions result in varying installation difficulties. To facilitate installation, PV panels are often installed following the terrain while avoiding power lines. To further minimize the impact of avoiding power lines on PV panel placement, the orientation and arrangement of the PV panels are adjusted to be parallel or nearly parallel to the power lines. The PV panels no longer face due south, but at an angle to it, specifically -30° to 30° in this embodiment. This increases the spacing between rows of PV panels, placing the power lines within the spacing between rows, reducing wasted land due to power line avoidance, increasing the PV panel area, increasing the number of PV panels per unit area, and improving land utilization.

[0054] The terrain where photovoltaic panels are installed is mostly irregular, so a single size of photovoltaic panel is difficult to meet the design requirements. Therefore, photovoltaic panels of different sizes are used in combination. First, large-size photovoltaic panels are used to deploy as many as possible in the area according to the principle of deploying as much as possible. For corner areas where large-size photovoltaic panels cannot be deployed, smaller-size photovoltaic panels are used instead.

[0055] By selecting areas near main roads where small-sized photovoltaic panels cannot be installed, box-type transformers can be deployed. This not only avoids the occupation of open land by the box-type transformers, allowing the land to be prioritized for photovoltaic panels and agricultural facilities, but also eliminates the need to build separate maintenance roads for the box-type transformers, reducing the land used for public facilities in the project and further improving land utilization.

[0056] To facilitate agricultural production management, agricultural management buildings are set up. By combining agricultural management buildings with mounting brackets, the construction cost of agricultural management buildings can be reduced.

[0057] A photovoltaic sub-array with a suitable land area, located near a main road and a box-type transformer, was selected for the construction of the agricultural management building. Utilizing BIPV technology, the mounting brackets were replaced with waterproof brackets, and galvanized magnesium-aluminum M-shaped main water tanks and U-shaped secondary water tanks were added. Waterproof photovoltaic panels served as the photovoltaic roof of the agricultural management building. The original single-row pipe piles were replaced with double-row pipe piles, which also serve as the foundation and columns of the building. Plain concrete strip foundations were used between the pipe piles as the wall base, and thin-walled C-shaped steel was used as the wall beams. The walls of the management building were constructed of lightweight fireproof materials, enclosing the area within the photovoltaic roof. Doors and windows were installed at appropriate locations on the walls, and a road was paved at the entrance to connect seamlessly with the main road. The indoor floor of the management building was raised 300mm above the outdoor floor and hardened with concrete. Power for the management building could be connected from the low-voltage side of the adjacent box-type transformer, saving on power supply lines.

[0058] Agricultural greenhouses are constructed between adjacent rows of photovoltaic panels, with the greenhouses built beneath the panels. A large-span arched structure serves as the roof, with the span of the arch equal to the net distance between rows of pipe piles. The arches are connected to the pipe piles via clamps, and the arch material can be round or square tubing. A tie rod is installed at each end of the front and rear supports of the installation bracket, connecting to the arches of the greenhouse in front and behind. Each greenhouse arch has two tie rods at the front and back, further enhancing the stability of the greenhouse structure. Arch rods and horizontal tie rods are installed between the arches to support the greenhouse film and insulation blankets. The pipe piles in the front and rear rows serve as the greenhouse's columns and foundation. No additional load-bearing columns are needed along the length of the greenhouse; instead, end supports are installed around the perimeter to support and shape the greenhouse film and insulation blankets. The distance between the outer facades of the front and rear rows along the length of the greenhouse should be ≥1.0m to facilitate maintenance of the greenhouse film and insulation blankets. A drainage ditch is constructed next to the pipe piles in the middle of the front and rear rows of greenhouses.

[0059] S200, pipe pile construction and photovoltaic panel installation.

[0060] After the design is completed, a pilot hole is excavated in the ground, and a pipe pile is inserted into the pilot hole. An installation bracket for installing photovoltaic panels is fixed at the top of the pipe pile, and the photovoltaic panels are fixed on the installation bracket.

[0061] S300 involves the construction of box-type transformers, agricultural greenhouses, and agricultural management buildings.

[0062] Example 2:

[0063] After photovoltaic panels are installed, settlement of the pipe piles is a common problem. This settlement can be caused by various factors, such as soft soil with insufficient bearing capacity, frost heave in cold winters, and reduced friction between the soil and piles due to thawing and shrinkage in summer. These factors can lead to deformation of the mounting brackets installed on the pipe piles. This deformation then puts stress on the photovoltaic panels, causing them to twist and deform slightly, ultimately leading to problems like microcracks.

[0064] Reference Figure 7 and Figure 8 The difference between Example 2 and Example 1 is that the pipe pile includes a pile body 1 with a hollow structure and a pile tip 2. The pile tip 2 is located at the bottom end of the pile body 1. Multiple sliding holes 4 are opened on the pile body 1. The multiple sliding holes 4 are arranged at intervals along the circumference of the pile body 1. The sliding holes 4 are arranged in multiple rings along the axial direction of the pile body 1. Each sliding hole 4 is provided with a nozzle 5.

[0065] Reference Figure 9The pile tip 2 includes a connecting plate 21 and a digging plate 22. The connecting plate 21 is fixed to the end face of the pile body 1, and the digging plate 22 is fixed to the side of the connecting plate 21 facing away from the pile body 1. A clearance hole communicating with the pile body 1 is passed through the center of the connecting plate 21, and the axis of the clearance hole is on the same straight line as the axis of the pile body 1. A plurality of mounting holes 8 are spaced apart on the circumferential surface of the connecting plate 21, and a nozzle 9 is fixed in each mounting hole 8.

[0066] As the pile 1 penetrates deeper into the ground, the excavation plate 22 cuts the soil, reducing the resistance as the pile 1 penetrates deeper. After the pile 1 reaches the designated depth, silicate cement grout is sprayed into the surrounding soil through the nozzle 5 and the spray nozzle 9 to grout the soil. After the cement grout solidifies, it forms a support platform, dispersing the pressure of the pile 1 on the soil, supporting the pile 1, improving the soil's support capacity for the pile 1, and mitigating the settlement of the pipe pile.

[0067] Reference Figure 8 and Figure 10 The nozzle 5 has a connecting block 14 integrally formed at one end inside the pile body 1, and the top surface of the connecting block 14 is inclined. A connecting post 3 is inserted into the pile body 1, and the bottom end of the connecting post 3 has a rounded transition. As the connecting post 3 penetrates deeper into the pile body 1, the rounded transition of the connecting post 3 abuts against the top surface of the connecting block 14, and the connecting post 3 pushes the nozzle 5 to slide radially outward from the pile body 1. The pile body 1 has grouting holes 6 that communicate with both the sliding hole 4 and the mounting holes 8 on the connecting plate 21. The nozzle 5 has a connecting hole 7 that communicates with the grouting holes 6, and the nozzle 9 communicates with the grouting holes 6.

[0068] Reference Figure 8 and Figure 10 Initially, the connecting hole 7 of the nozzle 5 is misaligned with the grouting hole 6 and is not connected. That is, the outer wall of the nozzle 5 divides the grouting hole 6 into multiple segments, and the connecting hole 7 on the nozzle 5 faces the inner wall of the sliding hole 4. After the pile body 1 is installed, the abutment column 3 is inserted into the pile body 1. When the abutment column 3 is inserted, it pushes the nozzle 5 to move outward from the pile body 1, and the connecting hole 7 connects with the grouting hole 6, thus connecting the multiple segments of the grouting hole 6. While maintaining the suspension of the abutment column 3, cement grout is injected into the grouting hole 6. The cement grout enters the nozzle 5 and the mounting hole 8 through the grouting hole 6, and then enters the nozzle 9 through the mounting hole 8, so that the nozzle 5 and the nozzle 9 together spray cement grout into the soil.

[0069] Reference Figure 8 and Figure 9 A grouting hole 11 is provided on the abutment column 3. The axis of the grouting hole 11 is on the same straight line as the axis of the pile body 1. A grouting pipe 10 is fixed on the bottom surface of the abutment column 3. The grouting pipe 10 is connected to the grouting hole 11, and the axis of the grouting pipe 10 is on the same straight line as the axis of the grouting hole 11.

[0070] After the abutment column 3 is fully inserted into the pile body 1, the grouting pipe 10 passes through the relief hole on the connecting plate 21 and is inserted into the soil. By injecting cement grout into the grouting hole 11, the grouting pipe 10 reinforces the soil below the pile body 1 and improves the support effect on the pile body 1.

[0071] Reference Figure 8 and Figure 11 A gap exists between the abutment post 3 and the inner wall of the pile body 1. A cap 12 is provided on the top surface of the pile body 1, and a grouting port 13 is opened on the cap 12. Before the abutment post 3 is inserted into the pile body 1, a release agent is applied to the side wall of the abutment post 3. After the abutment post 3 is fully inserted into the pile body 1, the cap 12 is fixed to the pile body 1, and the abutment post 3 and the cap 12 are fixed together. Cement grout is injected into the grouting port 13 to seal the cavity inside the pile body 1. After the cement grout has solidified, the cap 12 is removed, and the abutment post 3 is withdrawn from the pile body 1.

[0072] It should be noted that due to the significant differences in the properties of different soil layers, the reinforcing effect of cement grout on the soil is also different. In order to ensure the reinforcing effect of cement grout, before grouting the pile body 1, soil samples of the same depth as the nozzle 5 and nozzle 9 are taken for grouting simulation. The grouting time and the amount of cement grout injected are calculated based on the simulation results.

[0073] The construction process of Example 2 is as follows: Soil from the construction site is used for grouting simulation, and the grouting time and volume are calculated in advance. After fixing the pile tip 2 to the pile body 1, the pile body 1 is inserted to a specified depth below the ground surface. A release agent is applied to the surface of the abutment column 3, and the abutment column 3 is inserted into the pile body 1, causing the nozzle 5 to slide outward from the pile body 1, with the nozzle 5 protruding from the outer wall of the pile body 1. The cap 12 is fixed to the top surface of the pipe pile, and the abutment column 3 is fixedly connected to the cap 12. Cement grout is injected into the injection hole 11, the grouting hole 6, and the injection port 13 to form a support platform outside the pile body 1 and reinforce the pile body 1. After the cement grout solidifies, the cap 12 is removed, and the abutment column 3 is taken out of the pile body 1.

[0074] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
