Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic power generation facility construction, specifically to an integrated installation system platform for offshore photovoltaic power generators and its construction and installation method. Background Technology

[0002] In traditional offshore photovoltaic (PV) structure installation, the common approach is to integrate and assemble at the dock, transport the entire unit, and then hoist it onto the site. This approach is based on the fundamental assumption that integrated assembly line operations rely on large, stable sites. Based on this assumption, two technical paths have emerged in this field: one is to scale up the offshore platform (using larger transport ships or jack-up platforms) in an attempt to replicate the large-scale sites on land at sea. However, the deck area of ​​ships can never match that of land-based docks, and scaling up the platform leads to significantly increased costs, deeper drafts, and inability to access shallow water areas. The other approach relies on onshore or dockside assembly, transporting the complete unit to the sea as a whole. However, ultra-large units are easily damaged during transport due to ship swaying, and there is a lack of large lifting equipment on-site capable of precise positioning under swaying conditions.

[0003] Neither of the aforementioned approaches has overcome the inherent perception that assembly line operations must rely on large, stable sites. When the area of ​​the offshore platform is objectively limited and the environment is subject to movement, the industry generally believes that efficient and safe integrated assembly line operations cannot be directly achieved at sea. This technological bias has long constrained research in this field, causing engineers to constantly seek solutions within the framework of expanding the site or avoiding offshore operations.

[0004] Therefore, how to achieve integrated assembly line operations that originally required a large area of ​​stable space in marine conditions with limited area and swaying environment is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned technical issues, the aim is to provide an integrated installation system platform and construction and installation method for marine photovoltaic (PV) systems. This system enables efficient and safe in-situ assembly line assembly under the objectively limited area of ​​the offshore operating platform and the swaying environment. It avoids the problems of increased costs, increased draft, and limited shallow water areas caused by a single enlarged platform, and eliminates the risks of transportation damage after overall assembly on land and the difficulty of accurate positioning under swaying conditions at sea.

[0006] This invention is achieved through the following technical solution:

[0007] An integrated installation system platform for marine photovoltaic (PV) systems includes an unloading platform, a hoisting platform, and an installation platform. The unloading platform, hoisting platform, and installation platform are all independent working platforms installed on top of piles, and are arranged sequentially along the construction direction. The unloading platform and the hoisting platform, as well as the hoisting platform and the installation platform, are connected by connecting bridges or transport channels.

[0008] The beneficial effects of this invention are that, by adopting a structure in which the unloading platform, hoisting platform, and installation platform are set as three independent working platforms installed on the top of the pile, arranged sequentially along the construction direction and connected to each other by a connecting bridge or transport channel, the integrated assembly line operation, which originally required a large area of ​​stable space, can be disassembled into three independent small-area platforms for parallel and coordinated execution. This breaks through the long-standing technical prejudice in the field that assembly line operations must rely on a large area of ​​stable space. It achieves efficient and safe in-situ assembly line assembly under the objectively limited area of ​​offshore working platforms and environmental swaying conditions. It avoids the problems of increased costs, increased draft, and limited shallow water areas caused by a single enlarged platform, and eliminates the risks of transportation damage after overall assembly on land and the difficulty of accurate positioning under marine swaying conditions.

[0009] In some embodiments, the unloading platform is equipped with an unloading and stacking platform, which is installed on top of the piles. A hoisting platform is positioned above the unloading platform, and a hoisting pre-reserved opening is provided in the middle of the unloading and stacking platform. A single-beam double-trolley crane is located at the upper end of the unloading platform, directly above the hoisting pre-reserved opening. By adopting a structure where the unloading and stacking platform is installed at the bottom of the unloading platform and on top of the piles, and the hoisting platform is positioned above the unloading platform with a hoisting pre-reserved opening in the middle of the unloading and stacking platform, and the single-beam double-trolley crane is positioned directly opposite the opening, materials on the transport ship can be directly hoisted to the unloading and stacking platform via the hoisting pre-reserved opening. This achieves vertical spatial separation and smooth connection between unloading operations and subsequent hoisting operations, avoiding secondary material handling on the deck. Within the limited area of ​​the offshore platform, unloading and stacking functions are effectively integrated, providing an efficient material replenishment starting point for subsequent distributed assembly line operations.

[0010] In some embodiments, a support frame is provided at the bottom of the unloading platform. The support frame includes a main beam and secondary beams symmetrically arranged on both sides of the main beam. The main beam is horizontally supported at the bottom of the unloading platform, and pulleys are provided between the secondary beams and the main beam. The support frame can be moved forward by a moving device to transfer the load of the unloading platform to the top of the piles. Because of the support frame consisting of a main beam and secondary beams at the bottom of the unloading platform, with the main beam horizontally supported and the secondary beams and main beams transferring the load to the top of the piles, the unloading platform can evenly distribute the load to multiple pile tops through the overall rigidity of the welded frame when subjected to the dynamic impact load generated by the crane lifting materials and the overturning moment caused by sea waves. This significantly enhances the structural stability of the platform in swaying environments, thereby ensuring the safety and reliability of the unloading operation and providing a stable working foundation for subsequent assembly processes.

[0011] In some embodiments, the lifting platform includes a trolley transport platform; at least one transport trolley is mounted on the trolley transport platform, the transport trolley including a transport mobile flatbed and a transport bracket fixed to the transport mobile flatbed; a monorail gantry crane system is erected above the trolley transport platform and is arranged along the same track or adjacent to the travel trajectory of the transport trolley, enabling the transport trolley to directly transport the component to the lifting position below the monorail gantry crane system. Because of the structure that arranges the transport trolley and the monorail gantry crane system along the same track or adjacent to each other, and allows the transport trolley to directly transport the component to the lifting position below, the process from transfer to lifting does not require intermediate manual unhooking or secondary fixing. This eliminates the dangerous manual transition link in the swaying environment at sea, avoiding the risk of component collision and personnel injury, while significantly improving the efficiency and accuracy of lifting alignment, thus overcoming the technical bottleneck of traditional single-point lifting's difficulty in precise positioning under swaying conditions.

[0012] In some embodiments, a photovoltaic module transport assembly is further included, disposed between the unloading platform and the installation platform. The photovoltaic module transport assembly includes: photovoltaic module transport channels, photovoltaic module transport trolleys, and transport tracks. The transport tracks are laid along the surface of the unloading platform and the pre-installation platform surface of the installation platform, forming multiple photovoltaic module transport channels. The photovoltaic module transport trolleys are slidably mounted on corresponding transport tracks. This allows for the continuous and stable transfer of loose components such as support materials, purlins, and photovoltaic panels from the unloading platform to the pre-installation platform of the installation platform, achieving mechanization and streamlined material transfer. This avoids the inefficiency and safety hazards of manual handling in a swaying environment, thereby providing an uninterrupted material supply for parallel pre-assembly operations on the installation platform.

[0013] In some embodiments, the installation platform includes a pre-installation platform, auxiliary installation gantry frames, and auxiliary installation gantry frame moving tracks. The pre-installation platform is mounted on the top of the pile, and several auxiliary installation gantry frame moving tracks are laid parallel to each other on the pre-installation platform. The auxiliary installation gantry frames are slidably mounted on adjacent auxiliary installation gantry frame moving tracks, dividing the pre-installation platform into several installation units. These installation units are used to assemble photovoltaic modules. This allows the assembly of photovoltaic modules to be carried out simultaneously in multiple units, forming a standardized, modular assembly line pre-installation station. By moving the gantry frames along the tracks, the sequential hoisting of finished products from each unit onto the limited-area platform maximizes the parallel operation capability, thereby overcoming the efficiency limitations of sequential operation at a single station.

[0014] This invention also provides a construction and installation method based on the aforementioned marine photovoltaic (PV) generator integrated installation system platform, comprising the following steps: S1: mooring the transport ship in the middle channel of the unloading platform; S2: using the lifting equipment on the unloading platform to lift the truss components from the transport ship to the unloading platform, and after transfer, assembling the truss at the assembly position, and then using the lifting equipment to lift and fix the assembled truss onto the foundation piles; S3: using the lifting equipment on the unloading platform to lift the photovoltaic components from the transport ship to the unloading platform, and after transfer, pre-assembling the photovoltaic modules in the pre-assembly area of ​​the installation platform, and then lifting the pre-assembled photovoltaic module unit as a whole onto the installed truss and fixing it; S4: after completing the installation of one span, moving the unloading platform, the lifting platform, and the installation platform forward one pile distance in sequence and fixing them; S5: repeating steps S2 to S4 until all installations are completed. By decomposing the construction process into three core steps—truss hoisting, assembly and fixing, photovoltaic component transfer, pre-assembly and overall hoisting, and the sequential migration of the three platforms after completing one span—and executing them cyclically, truss installation and photovoltaic module pre-installation can be carried out in time or in part in parallel. Furthermore, by migrating sequentially, the production line can be continuously transferred between different pile spans. From a methodological perspective, the reliance on large-area stable sites on land is completely eliminated, and a complete in-situ cyclic production line operation process is constructed in the swaying and confined working environment at sea.

[0015] In some embodiments, step S2 includes: using a single-beam double-trolley crane on the unloading platform to lift the truss components from the transport ship to the unloading and stacking platform; transferring the truss components to the pre-installation platform of the installation platform via a transport trolley; assembling and connecting long and short truss sections into a complete truss on the unloading and stacking platform or the pre-installation platform; and hoisting and fixing the truss to the foundation piles via a monorail gantry crane system erected on the hoisting platform. Because step S2 utilizes a single-beam double-trolley crane to lift the truss components to the unloading and stacking platform, transfers them via a transport trolley to the pre-installation platform, and completes the truss assembly on the unloading and stacking platform or the pre-installation platform before hoisting and fixing them via a monorail gantry crane system, the truss assembly position can be flexibly selected according to site conditions (stacking platform or pre-installation platform) to fully utilize limited space. Simultaneously, the close connection between the transport trolley and the gantry crane achieves a short-process transfer from assembly to hoisting, thereby ensuring the accuracy and efficiency of truss installation even in swaying environments.

[0016] In some embodiments, step S3 includes: using a single-beam double-trolley crane on the unloading platform to lift the support material, purlins, and photovoltaic panels from the transport ship to the unloading and stacking platform; transferring the support material, purlins, and photovoltaic panels to the pre-installation platform of the installation platform through a photovoltaic module transport channel, the photovoltaic module transport channel including a photovoltaic module transport trolley and a transport track; installing the support material and purlins on the purlin installation bracket on the pre-installation platform, stacking the photovoltaic panels on the purlins to form an uninstalled photovoltaic unit, and fixing the uninstalled photovoltaic unit on the photovoltaic module transport trolley; transporting the assembled unit to a designated position to complete the final support fixing and photovoltaic panel installation, forming a photovoltaic panel pre-installation unit; and hoisting the photovoltaic panel pre-installation unit as a whole onto the installed truss and fixing it through an auxiliary installation gantry. Because of the multi-stage operation adopted in step S3, in which photovoltaic components are hoisted to the unloading and stacking platform by a single-beam double-trolley crane, transferred to the pre-installation platform via the photovoltaic module transport channel, purlin bracket installation and photovoltaic panel stacking to form uninstalled units are completed on the pre-installation platform, and then the pre-installation units are hoisted as a whole onto the installed truss by the auxiliary installation gantry, most of the photovoltaic module assembly work is completed on the pre-installation platform, with only the final step involving overall hoisting. This significantly reduces the amount of high-altitude work at sea. At the same time, the track travel and overall hoisting functions of the auxiliary gantry enable rapid positioning, thereby improving installation safety and construction speed.

[0017] In some embodiments, step S4 specifically includes: sequentially moving the unloading platform and the installation platform forward by one pile distance and fixing them; the hoisting platform moves by traction from the installation platform. Specifically, the unloading platform moves by moving its main beam at the pile stop, and then moves other associated devices by moving the upper unloading platform's sub-beam; the installation platform moves by using a track laid at its bottom; and the hoisting platform moves by traction from the installation platform. Because of the time-sequential coordinated step-by-step migration method adopted in step S4, which involves moving the unloading platform forward by one pile distance and fixing it, then moving the installation platform forward by one pile distance and fixing it, and finally moving the hoisting platform as a whole under the traction of the installation platform, and finally moving (towards the area where the photovoltaic subarray is not installed) and fixing it, and because each platform adapts to the movement by relying on the walking mechanism beam, the moving track and the support frame, the three independent platforms can move forward with precise timing and reliable movement mechanism after completing the installation of one span. This not only does not interrupt the process connection of each platform, but also ensures the relative position accuracy between the platforms after migration, thereby realizing seamless cyclic operation of the production line between multiple spans, and completely breaking through the inefficient mode of traditional single platform overall movement or ship positioning.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] 1. By adopting a structure in which the unloading platform, hoisting platform, and installation platform are set as three independent working platforms installed on the top of the piles and arranged sequentially along the construction direction and connected to each other by connecting bridges or transportation channels, the integrated assembly line operation, which originally required a large area of ​​stable site, can be disassembled into three independent small-area platforms for parallel and coordinated execution. This breaks through the long-standing technical bias in this field and achieves efficient and safe in-situ assembly line assembly under the objectively limited area of ​​offshore working platforms and environmental swaying conditions. It avoids the problems of increased costs, increased draft, and limited shallow water areas caused by a single enlarged platform, and eliminates the risks of transportation damage after overall assembly on land and the difficulty of accurate positioning under marine swaying conditions.

[0020] 2. Because the structure adopts the arrangement of the transport trolley and the monorail gantry crane system on the same rail or adjacent to each other, and the transport trolley directly transports the components to the area below the hoisting position, the process from transfer to hoisting of the components does not require manual unhooking or secondary fixing in the middle. In the swaying environment at sea, the dangerous manual transition link is eliminated, avoiding the risk of component collision and personnel injury.

[0021] 3. The photovoltaic components are hoisted to the unloading and stacking platform using a single-girder double-trolley crane, then transferred to the pre-installation platform via the photovoltaic module transport channel. On the pre-installation platform, the purlin brackets are installed and the photovoltaic panels are stacked to form the uninstalled units. Finally, the pre-installation units are hoisted onto the installed trusses by the auxiliary installation gantry. This multi-stage operation allows most of the photovoltaic module assembly work to be completed on the pre-installation platform, with only the final step involving overall hoisting. This significantly reduces the amount of high-altitude work at sea. At the same time, the track travel and overall hoisting functions of the auxiliary gantry enable rapid positioning, thereby improving installation safety and construction speed.

[0035] Example 1

[0036] like Figures 1-6 As shown, this embodiment 1 provides an integrated installation system platform for a marine photovoltaic (PV) system, including an unloading platform 100, a hoisting platform 200, and an installation platform 300. The unloading platform 100, hoisting platform 200, and installation platform 300 are all independent working platforms installed on the top of the piles, and the three are arranged sequentially along the construction direction. The unloading platform 100 and the hoisting platform 200, and the hoisting platform 200 and the installation platform 300 are connected by connecting bridges or transport channels.

[0037] See Figures 1-3 The unloading platform 100 is equipped with an unloading stacking platform 130, which is installed on the top of the pile. The hoisting platform 200 is arranged above the unloading platform 100, and a hoisting reserved opening 140 is opened in the middle of the unloading stacking platform 130. A single beam double trolley crane 120 is provided at the upper end of the unloading platform 100, and the single beam double trolley crane 120 is located directly above the hoisting reserved opening 140. By adopting a structure in which an unloading and stacking platform 130 is set at the bottom of the unloading platform 100 and installed on the top of the pile, and a hoisting platform 200 is arranged above the unloading platform 100, a hoisting reserved opening 140 is opened in the middle of the unloading and stacking platform 130, and a single-beam double-trolley crane 120 is arranged facing the opening, the materials on the transport ship 6 can be directly hoisted to the unloading and stacking platform 130 through the hoisting reserved opening 140 by the crane. This achieves spatial separation and smooth connection between unloading operations and subsequent hoisting operations in the vertical direction, avoids secondary transfer of materials on the deck, and effectively integrates unloading and stacking functions within the limited area of ​​the offshore platform, thus providing an efficient material replenishment starting point for subsequent distributed assembly line operations.

[0038] Specifically, the unloading platform 100 is equipped with two single-beam double-trolley cranes 120. The projection distance between the hooks of the two cranes on the horizontal plane is adjustable to match trusses of different lengths and achieve synchronous lifting at two points. Due to the use of a dual-crane collaborative lifting structure with adjustable spacing, both ends of the long truss can be lifted simultaneously, effectively reducing the vertical displacement difference between the two ends of the component in a swaying marine environment and avoiding the risk of swaying and collision caused by single-point lifting.

[0039] See Figures 1-3 The unloading platform 100 has a support frame 110 at its bottom. The support frame 110 includes a main beam 111 and secondary beams 112 symmetrically arranged on both sides of the main beam 111. The main beam 111 is horizontally supported at the bottom of the unloading platform 100. Pullers are installed between the secondary beams 112 and the main beam 111, allowing the platform to move forward via a moving device and transfer the load of the unloading platform to the pile tops. Because of the support frame 110 consisting of the main beam 111 and secondary beams 112 at the bottom of the unloading platform 100, with the main beam 111 horizontally supported and the secondary beams 112 and main beam 111 transferring the load to the pile tops, the unloading platform 100 can evenly distribute the load to multiple pile tops through the overall rigidity of the welded frame when subjected to dynamic impact loads generated by cranes lifting materials and overturning moments caused by sea waves. This significantly enhances the structural stability of the platform in swaying environments, ensuring the safety and reliability of unloading operations and providing a stable working foundation for subsequent assembly processes. (See also...) Figures 1-5 The hoisting platform 200 includes a trolley transport platform 220; at least one transport trolley 210 is mounted on the trolley transport platform 220, the transport trolley 210 includes a transport mobile flatbed 211 and a transport bracket 212 fixed on the transport mobile flatbed 211; a monorail gantry crane system 230 is erected above the trolley transport platform 220 and is arranged along the same track or adjacent to the travel trajectory of the transport trolley 210, so that the transport trolley 210 can directly transport the components to the hoisting position below the monorail gantry crane system 230. By adopting a structure in which the transport trolley 210 and the monorail gantry crane system 230 are arranged on the same rail or adjacent to each other, and the transport trolley 210 directly transports the components to the area below the hoisting position, the process from transfer to hoisting does not require manual unhooking or secondary fixing in the middle. In the swaying environment at sea, the dangerous manual transition link is eliminated, avoiding the risk of component collision and personnel injury. At the same time, the efficiency and accuracy of hoisting and positioning are greatly improved, thus breaking through the technical bottleneck of traditional single-point hoisting which is difficult to accurately position under swaying conditions.

[0040] See Figure 1 and Figure 6The system also includes a photovoltaic module transport assembly, which is positioned between the unloading platform 100 and the installation platform 300. The photovoltaic module transport assembly includes: photovoltaic module transport channels 70, photovoltaic module transport trolleys 71, and transport tracks 72. The transport tracks 72 are laid along the surface of the unloading platform 100 and the pre-installation platform 310 of the installation platform 300, forming multiple photovoltaic module transport channels 70. The photovoltaic module transport trolleys 71 are slidably mounted on corresponding transport tracks 72. This allows for the continuous and stable transfer of components such as support materials, purlins, and photovoltaic panels from the unloading platform 100 to the pre-installation platform 310 of the installation platform 300, achieving mechanization and streamlined material transfer. This avoids the inefficiency and safety hazards of manual handling in a swaying environment, thus providing an uninterrupted material supply for parallel pre-assembly operations on the installation platform 300.

[0041] Specifically, each installation unit is provided with a purlin mounting bracket 350; an uninstalled photovoltaic unit 360 is placed on the purlin mounting bracket 350, and the uninstalled photovoltaic unit 360 is composed of photovoltaic panels stacked on the purlin; the auxiliary installation gantry 330 is used to hoist the photovoltaic panel pre-installation unit 340 assembled on the pre-installation platform 310 as a whole onto the installed connecting truss; the photovoltaic panel pre-installation unit 340 includes purlins fixed to the purlin mounting bracket 350 and photovoltaic panels stacked on the purlins.

[0042] See Figures 1-5 The installation platform 300 includes a pre-installation platform 310, an auxiliary installation gantry 330, and auxiliary installation gantry moving tracks 320. The pre-installation platform 310 is installed on the top of the pile. Several auxiliary installation gantry moving tracks 320 are laid parallel to each other on the pre-installation platform 310. The auxiliary installation gantry 330 is slidably installed on adjacent auxiliary installation gantry moving tracks 320, dividing the pre-installation platform 310 into several installation units. The installation units are used to assemble photovoltaic modules. The span of the auxiliary installation gantry 330 is greater than or equal to the overall width of the photovoltaic panel pre-installation unit 340, and its lifting mechanism is hydraulically driven, enabling horizontal fine-tuning and alignment after vertical lifting to ensure precise docking with the truss during overall hoisting. This allows the assembly of photovoltaic modules to be carried out simultaneously in multiple units, forming a standardized and modular assembly line pre-installation station. By moving the gantry along the tracks, the sequential hoisting of finished products from each unit is achieved, maximizing the parallel operation capability on a platform with limited area, thereby overcoming the efficiency limitations of sequential operation at a single station.

[0043] Specifically, the unloading platform 100 includes a main beam 111 and a secondary beam 112. The main beam 111 is extended outwards and moved to the top of the new pile by a jacking cylinder and fixed thereon. A chain conveyor mechanism is provided between the main beam 111 and the secondary beam 112, which is used to move the secondary beam 112 and its upper components together to the top of the new pile. A moving track is laid at the bottom of the installation platform 300 to allow it to move along the track. Rollers are installed at the bottom of the hoisting platform 200, and these rollers cooperate with a guide rail located above the installation platform 300, allowing the hoisting platform 200 to move along the guide rail. This system eliminates the need for external auxiliary vessels, enabling long-distance autonomous migration, completely freeing construction rhythm from the constraints of vessel scheduling, and enhancing the system's independent operation capability.

[0044] Example 2

[0045] This embodiment 2 provides a construction and installation method based on the aforementioned marine photovoltaic integrated installation system platform, including the following steps:

[0046] S0: Based on the pile dimensions, elevation, and spacing of the offshore photovoltaic construction drawings, fabricate and install each component, and install the un-photovoltaic subarray area 5 of the unloading platform 100, hoisting platform 200, and installation platform 300.

[0047] S1: Moor the transport ship 6 in the middle channel of the unloading platform 100, and position the transport ship 6 directly below the effective working range of the single-beam double-trolley crane 120 on the unloading platform 100.

[0048] S2: The truss components are hoisted from the transport ship 6 to the unloading and stacking platform 130 using the single-beam double-trolley crane 120 on the unloading platform 100; the truss components are transferred to the pre-installation platform 310 of the installation platform 300 via the transport trolley 210; the long and short truss sections are assembled and connected into a complete truss on the unloading and stacking platform 130 or the pre-installation platform 310; the assembled truss is hoisted and fixed to the foundation piles by the monorail gantry crane system 230 erected on the hoisting platform 200; when hoisting the long truss, two single-beam double-trolley cranes 120 are used to hoist both ends of the long truss respectively to achieve synchronous hoisting at two points, so as to reduce the vertical displacement difference under swaying environment.

[0049] S3: Using the single-beam double-trolley crane 120 on the unloading platform 100, the support materials, purlins, and photovoltaic panels are hoisted from the transport ship 6 to the unloading and stacking platform 130; the materials are transferred to the pre-installation platform 310 of the installation platform 300 via the photovoltaic module transport channel 70; on the pre-installation platform 310, the support materials and purlins are installed on the purlin installation brackets 350, the photovoltaic panels are stacked on the purlins to form uninstalled photovoltaic units 360, and the uninstalled photovoltaic units 360 are fixed to the photovoltaic module transport... On the trolley 71, the assembled unit is transported to the designated position, and the final bracket fixing and photovoltaic panel installation are completed to form a photovoltaic panel pre-installation unit 340. The photovoltaic panel pre-installation unit 340 is hoisted onto the installed truss and fixed by the auxiliary installation gantry 330 to form the installed photovoltaic sub-array area 4. The auxiliary installation gantry 330 moves along the track to above the pre-installation unit, and its span covers the overall width of the photovoltaic panel pre-installation unit 340. After being lifted vertically by hydraulic drive, it is horizontally fine-tuned for alignment.

[0050] S4: After completing the installation of one span, retract the lifting support legs of each platform to detach them from the top of the pile; move the unloading platform 100 and the installation platform 300 forward by one pile distance and fix them in place; finally, the hoisting platform 200 moves by traction from the installation platform 300. Specifically, the unloading platform 100 moves by moving the main beam 111 of the unloading platform while it is fixed on the pile, and then moves the other upper components by moving the secondary beam 112 of the upper unloading platform. The installation platform 300 moves by using a moving track laid at its bottom, and the hoisting platform 200 moves by traction from the installation platform.

[0051] S5: Repeat steps S2 to S4 until the entire installation is complete.

[0052] By adopting the above steps, the truss installation and photovoltaic module pre-installation can be carried out in a time-sharing or partially parallel manner. Furthermore, the continuous transfer of the production line between different pile spans is achieved through sequential migration.
