Description

Technical Field

[0001] This invention relates to the field of photovoltaic construction technology, and more specifically to a method for rapid horizontal arrangement of photovoltaic modules. Background Technology

[0002] In the field of new energy, the installation method of photovoltaic (PV) modules directly affects the construction efficiency and cost control of PV power generation systems. Currently, traditional PV module installation mainly relies on manual installation, piece by piece, requiring workers to constantly adjust their positions as the installation progresses. This installation method has several drawbacks: 1. Traditional installation methods require one person to push the photovoltaic modules and two people to install the bolts for fixing. This requires multiple people to work together and results in wasted time. Each photovoltaic panel requires four sets of bolts, which is a large number of bolts used, wasting materials and increasing the tightening time. 2. Frequent relocation of work sites by workers necessitates the rearrangement of safety measures, which not only wastes time but also increases safety risks during construction due to the movement of work sites. 3. It is difficult to adapt to automated equipment such as robots or robotic arms for large-scale installation, which limits the improvement of installation efficiency and quality. Summary of the Invention

[0006] In a preferred embodiment, in step S1, the C-beam has an internal hollow structure.

[0007] In a preferred embodiment, the top surface of the C-shaped beam is fixedly connected to the fixing plate by bolts on the top of the C-shaped beam. The fixing plate is arranged parallel to the top surface of the C-shaped beam and is used to clamp and fix the photovoltaic modules at the edges.

[0008] In a preferred embodiment, in step S2, the ends of the conveying rails are provided with hinges, multiple conveying rails are rotatably hinged together by the hinges, and scale strips are provided on the sides of the conveying rails.

[0009] In the preferred embodiment, the bottom of the conveyor rail is provided with a magnetic absorbing plate, which is magnetically connected to the T-beam and the C-beam; the inner side of the conveyor rail is provided with a guide roller, which makes rolling contact with the photovoltaic module.

[0010] In a preferred embodiment, in step S6, a guide rail is provided on the bottom surface of the intermediate pressure plate, and the guide rail is engaged between the photovoltaic modules to limit and guide the photovoltaic modules; a flexible protective pad is provided at the contact surface between the intermediate pressure plate and the photovoltaic modules.

[0011] In a preferred embodiment, a conical platform is vertically arranged at the center of the bottom surface of the intermediate pressure plate, and an installation hole is provided on the T-beam. The bottom surface of the conical platform is vertically connected to the screw, and the other end of the screw passes through the installation hole and is threadedly connected to the pressure plate fixing bolt.

[0012] In a preferred embodiment, a third pressure plate is provided at the bottom surface of the pressure plate fixing bolt, and a spring sheet is provided at the contact surface between the third pressure plate and the T-beam.

[0013] In the preferred embodiment, the specific arrangement steps of step S1 include: S1.1 Align the groove on the bottom surface of the T-beam with the purlin of the photovoltaic bracket, so that the hook plate of the T-beam engages with one end of the T-beam fixing bolt; S1.2. Pass the other end of the T-beam fixing bolt through the purlin and thread it to the T-beam fixing nut. Install the first pressure plate on the upper end face of the T-beam fixing nut and tighten the nut so that the first pressure plate clamps and fixes the purlin and the T-beam. S1.3 Align the groove on the bottom surface of the C-beam with the purlin of the photovoltaic bracket, so that the hook plate of the C-beam engages with one end of the C-beam fixing bolt; S1.4.

[0014] A method for rapid horizontal arrangement of photovoltaic modules has the following beneficial effects, including but not limited to: 1. Utilizing a support structure of T-beams and C-beams, photovoltaic panels can be directly placed between the beams, eliminating the need for multiple people to support them in traditional methods. A single person can complete the positioning and installation of the panels, significantly reducing labor requirements. The guide rails are articulated and quickly fixed to the beams, allowing the photovoltaic modules to slide laterally along the rails for transport. This significantly improves installation efficiency compared to traditional manual handling, making it particularly suitable for large-scale, long-distance photovoltaic array construction. 2. The centralized transport of photovoltaic modules via guide rails reduces frequent movement of the construction work surface and lowers the frequency of safety measure resetting. Simultaneously, the robotic arm's design for grasping and transporting photovoltaic panels along the guide rails can replace manual high-altitude handling, reducing personnel climbing and movement, and effectively lowering safety risks during construction. 3. Optimize the clamping block fixing structure to reduce the number of bolts, thereby lowering material costs and tightening time. The guide rail is installed using a magnetic attraction method, and can be folded and reused after removal, reducing the consumption of auxiliary materials and further controlling installation costs; 4. The fixing plate and pressure block at the top of the C-shaped beam cooperate to form a clamping structure, enhancing the photovoltaic modules' resistance to wind loads and preventing side-blowing. The scale on the side of the guide rail and the limiting design of the pressure plate guide rail improve the positioning accuracy of the photovoltaic panel installation, ensuring the reliability of subsequent electrical connections.

Detailed Implementation

[0017] Example 1: Standard implementation of a method for rapid lateral placement of photovoltaic modules: S1. Beam installation and fixing: S1.1 Align the groove on the bottom surface of the T-beam 2 with the purlin 1 of the photovoltaic support, so that the hook plate 204 of the T-beam engages with one end of the T-beam fixing bolt 201; the other end of the T-beam fixing bolt 201 passes through the purlin 1 and is threadedly connected to the T-beam fixing nut 202. Install the first pressure plate 203 on the upper end face of the T-beam fixing nut 202, and tighten the nut to clamp and fix the purlin 1 and the T-beam 2 with the first pressure plate 203. The T-beam 2 adopts an internal hollow structure to reduce weight while ensuring support strength; S1.2 Align the groove on the bottom surface of the C-beam 3 with the purlin 1 of the photovoltaic bracket, so that the C-beam hook plate 304 engages with one end of the C-beam fixing bolt 301; the other end of the C-beam fixing bolt 301 passes through the purlin 1 and is threadedly connected to the C-beam fixing nut 302. Install the second pressure plate 303 on the upper end face of the C-beam fixing nut 302, and tighten the nut to clamp and fix the purlin 1 and the C-beam 3. Fix the fixing plate 305 to the top surface of the C-beam 3 using the C-beam top bolt 306. The fixing plate 305 is set parallel to the top surface of the C-beam 3 and is used to clamp the photovoltaic modules 9 at the edges later. S2, Guide Rail 5 Layout and Assembly: Based on the installation length of the photovoltaic module 9, multiple conveying rails 5 are rotatably hinged at their ends via hinges 6 to form a continuous conveying track; magnetic plates 8 are installed at the bottom of the conveying rails 5, which are quickly fixed to the top support surfaces of the T-beam 2 and C-beam 3 by magnetic attraction; the scale strips on the side of the conveying rails 5 are used to accurately position the installation position of the photovoltaic module 9 to ensure the array arrangement accuracy; S3, Photovoltaic Module 9 Transmission and Positioning: A robotic arm is used to pick up the photovoltaic module 9 and place it on the conveyor rail 5. Under its own weight and with human assistance, the photovoltaic module 9 rolls and moves along the guide roller 7 on the inner side of the conveyor rail 5 to the preset installation position. The photovoltaic module 9, which has been conveyed to the designated position, is aligned with the support structure of the T-beam 2 and C-beam 3 to complete the initial positioning and expose the corners and side areas of the photovoltaic module 9. S4, dismantling of guide rail 5 and fixing of pressure block: Utilizing the detachable nature of the magnetic chuck 8, the conveyor rail 5 is quickly removed and folded away via the hinge 6 for easy reuse. An intermediate pressure plate 4 is installed at the corner of the photovoltaic module 9. The guide rail 401 on the bottom surface of the intermediate pressure plate 4 engages between the photovoltaic modules 9, providing positioning guidance. A flexible pad 402 is placed on the contact surface between the intermediate pressure plate 4 and the photovoltaic module 9. The conical platform 403 at the axial center of the bottom surface of the intermediate pressure plate 4 passes through the mounting hole 205 of the T-beam 2 via a screw 404 and is threadedly connected to the pressure plate fixing bolt 405. A spring sheet 407 is placed between the third pressure plate 406 on the bottom surface of the pressure plate fixing bolt 405 and the T-beam 2, forming an elastic fastening structure after tightening. S5, Side anti-pinch reinforcement: At the side edge of the photovoltaic module 9 array, a Z-shaped pressure plate is installed corresponding to the hole position of the T-beam 2. One side of the Z-shaped pressure plate is attached to the side surface of the photovoltaic module 9, and the other side is fastened to the hole position of the T-beam 2 by bolts to form an anti-side-lifting fixing structure.

[0018] Example 2: Optimized Implementation of Large-Scale Construction: S1. Modular pre-installation of beams: For megawatt-level photovoltaic bases, T-beams 2 and C-beams 3 are pre-assembled into beam modules on the ground at preset intervals. T-beams 2 are fixed to purlins 1 via T-beam hook plates 204, T-beam fixing bolts 201, and first pressure plates 203. C-beams 3 are fixed to purlins 1 via C-beam hook plates 304, C-beam fixing bolts 301, and second pressure plates 303. Fixing plates 305 are pre-installed on the top of C-beams 3. The beam modules are then installed onto the photovoltaic support structure using hoisting equipment, improving the efficiency of high-altitude operations. S2, Guide Rail 5 Cluster Deployment: The conveyor rails 5 are spliced ​​together in 50-meter lengths to form guide rail modules, which are connected by hinges 6 and fixed by magnetic 8; scale lines are marked on the side of the guide rail modules, and with the help of a total station for positioning, the guide rails 5 are accurately extended along the lateral arrangement direction of the photovoltaic modules 9; at the same time, multiple sets of guide rails 5 are deployed and installed in parallel to form a matrix conveying system. S3, Automated conveying of robotic arm clusters: Five robotic arms are used to form a working unit. Each robotic arm is responsible for picking up photovoltaic modules 9 in a specific area. The robotic arms use a vision positioning system to identify the scale marks on the conveyor rail 5 and accurately place the photovoltaic modules 9 at the starting end of the guide rail 5. The photovoltaic modules 9 automatically slide to the preset position under the action of the guide roller 7, and the robotic arms perform positioning calibration at the same time. S4. Quick fastening and quality inspection: Automatic torque wrenches were used to tighten the bolts 405 of the intermediate pressure plate 4 in batches, and the tightening torque of the bolts corresponding to the cross-shaped pressure blocks was controlled within the standard range. After tightening, the flatness of the photovoltaic module 9 was checked by a laser rangefinder, and the error was controlled within the allowable range. The Z-shaped pressure plate was installed at the same time, and pneumatic tools were used to complete the side anti-lifting fixation. S5, guide rail 5 cyclic reuse process: After the single-zone photovoltaic module 9 is installed, the conveyor rail 5 is removed by a robotic arm and folded to 1 / 3 of its original length using hinges 6. The folded conveyor rail 5 is then transported to the next work area by a logistics trolley. It can be reused at least 50 times, significantly reducing the cost of auxiliary materials.
