Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic installation technology, and in particular to a marine photovoltaic integrated installation system. Background Technology

[0002] Currently, offshore photovoltaic (PV) systems mainly employ a modular hoisting method: PV modules are first assembled on shore, then transported to the construction area by ship, and subsequently hoisted onto the top of the PV pile using the ship's onboard lifting mechanism, finally secured manually. However, this method suffers from problems such as high construction difficulty, high safety risks, low efficiency, and high costs.

[0003] Some companies have attempted to adopt an integrated platform installation solution, which involves setting up a mobile work platform on top of the photovoltaic piles for the transfer, assembly, and installation of components. However, this method has the following problems: 1. Excessive load on the pile top: The platform's heavy weight leads to excessive pressure on the contact surface at the pile top, easily causing wear on the concrete surface, uneven settlement of the pile body, and damage to the anti-corrosion coating; 2. Difficulty in movement control: The platform needs to be moved with multi-point support on the discretely distributed photovoltaic pile tops, but due to the height difference at the pile tops and the heavy weight of the platform, the control precision during movement is insufficient, the walking mechanism malfunctions frequently, and the movement speed is limited, ultimately affecting construction efficiency.

[0004] Therefore, the current market urgently needs a marine photovoltaic integrated installation system that is highly secure, low-cost, has minimal impact on photovoltaic piles, and is highly efficient in construction. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems of high construction difficulty, low efficiency and high cost in the existing technology of offshore photovoltaic installation, and to propose an integrated system for offshore photovoltaic installation.

[0006] To achieve the above objectives, the present invention provides a marine photovoltaic installation integration system, which includes an installation platform that needs to be placed on a marine truss. The installation platform includes an electrically operated installation platform and an assembly platform. The electrically operated installation platform is fixedly connected to the assembly platform. A walking device is fixedly installed at the bottom of the electrically operated installation platform, enabling the installation platform to move autonomously on the marine truss.

[0007] Furthermore, the electric mounting platform has a long strip structure.

[0008] Furthermore, the electric mounting platform is longer than the assembly platform, and the assembly platform is located at the front end of the area between two adjacent electric mounting platforms. The two are fixedly connected and their upper surfaces are flush, together forming the assembly area.

[0009] Furthermore, the installation platform also includes a transport trolley A, which is located in the assembly area and is capable of moving within the assembly area.

[0010] Furthermore, the installation platform also includes an auxiliary installation gantry, which is horizontally mounted across two adjacent electric installation walkways. Its two ends are respectively supported on the tracks of the two electric installation walkways and can move longitudinally along the tracks.

[0011] Furthermore, the marine photovoltaic integrated installation system also includes a hoisting platform mounted on the marine truss, which can transport photovoltaic module components to the installation platform.

[0012] Furthermore, the hoisting platform includes an electric transport walkway longitudinally arranged on the marine truss, and a traveling device A is provided at the bottom of the electric transport walkway, with its tail end connected to the head end of the electric installation walkway.

[0013] Furthermore, the hoisting platform also includes an electric support walkway, hoisting equipment, and a transverse transport plate. The electric support walkway is longitudinally arranged on the marine truss and has a traveling device B at its bottom, located on both sides of the electric transport walkway and arranged parallel to it. The hoisting equipment is installed on the electric support walkway, and the transverse transport plate is located above the front ends of the electric support walkway and the electric transport walkway and is fixedly connected to both.

[0014] Furthermore, the marine photovoltaic integrated installation system also includes an unloading platform that needs to be placed on top of the marine photovoltaic piles. The unloading platform can lift the truss and photovoltaic module components onto the lifting platform.

[0015] Furthermore, the unloading platform includes two symmetrically arranged traveling mechanisms, column-supported rail beams, supporting trusses, and lifting equipment. The traveling mechanisms are installed on the top of the photovoltaic piles as the foundation for platform movement. The column-supported rail beams are vertically fixed above the traveling mechanisms. The supporting trusses are erected on the top of the column-supported rail beams, and slide rails are laid on their upper part. The lifting equipment is connected across the slide rails of the two supporting trusses and can move longitudinally along the slide rails.

[0016] Furthermore, the unloading platform also includes a construction platform, which is set between the two column-supported rail beams.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model relates to a marine photovoltaic integrated installation system. The integrated installation system includes an installation platform that needs to be placed on a marine truss. The installation platform includes a motorized installation walkway and an assembly platform. The motorized installation walkway is fixedly connected to the assembly platform. A walking device is provided at the bottom of the motorized installation walkway, allowing the installation platform to move autonomously on the marine truss. During construction, the installation system is placed on the already installed truss, avoiding the problem of excessive pressure on the pile top contact surface due to the weight of the platform, which could lead to wear on the pile top concrete surface, uneven settlement of the pile body, and damage to the anti-corrosion coating.

[0018] 2. In this utility model of marine photovoltaic integrated installation system, when the installation platform and unloading platform move forward, it is only necessary to control each electric walkway to move forward. Since the electric walkway is a long strip structure, this design effectively overcomes the problems of poor movement accuracy, high failure rate and slow speed caused by the height difference of photovoltaic piles and the heavy overall platform in traditional installation platforms. In addition, the installation platform and unloading platform integrate the functions of transportation, assembly and installation of photovoltaic modules and trusses, which greatly improves the installation efficiency.

[0019] 3. The marine photovoltaic integrated installation system of this utility model achieves automated transfer of truss and photovoltaic module components through the efficient coordination of the hoisting platform and the unloading platform, which greatly reduces the number of construction personnel and improves the transfer efficiency of truss and photovoltaic modules.

[0020] 4. This utility model of marine photovoltaic integrated installation system integrates the functions of hoisting, transporting, assembling and installing photovoltaic modules and trusses through the efficient coordination of unloading platform, hoisting platform and installation platform. It has the advantages of simple construction, high efficiency, good safety and low cost. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0024] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0025] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Furthermore, in the description of this application, the terms "front end" and "back end" are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Example 1

[0027] like Figure 1-2This embodiment provides a marine photovoltaic integrated installation system, including an installation platform 1 that needs to be placed on a marine truss 4. The installation platform 1 includes an electric installation walkway 11 and an assembly platform 12. The electric installation walkway 11 and the assembly platform 12 are fixedly connected. A walking device is fixedly installed at the bottom of the electric installation walkway 11. The walking device can walk on the marine truss 4 that has been installed on the top of the photovoltaic pile, so that the installation platform 1 can move autonomously on the marine truss 4. The truss 4 has an inverted triangular structure.

[0028] During construction, the installation platform 1 is first placed at a designated position on the offshore truss 4, which has already been installed on top of the photovoltaic piles. Then, the individual photovoltaic modules are transported from the outside to the assembly platform 12 for assembly. Finally, the assembled photovoltaic modules 6 are installed onto the offshore truss 4. After all the photovoltaic modules 6 at this position are installed, the driving device moves along the truss to the next position, and the installation of photovoltaic modules 6 at the next position is completed using the same method. This process is repeated until all photovoltaic modules 6 are installed. Compared to the traditional method of placing the installation platform on top of the photovoltaic piles for assembly and installation, this method assembles and installs the photovoltaic modules 6 on the truss. This avoids the problems of excessive pressure on the pile top contact surface due to the weight of the platform, which can lead to wear on the pile top concrete surface, uneven pile settlement, and damage to the anti-corrosion coating. It also effectively overcomes the problems of poor platform movement accuracy and high failure rate caused by the height difference of the photovoltaic piles 5.

[0029] More preferably, when the photovoltaic installation area is large, multiple motorized mounting walkways 11 and assembly platforms 12 can be set up. The motorized mounting walkways 11 are elongated, and the assembly platforms 12 are rectangular, with the motorized mounting walkways 11 being longer than the assembly platforms 12. Each assembly platform 12 is located at the front end of the area between two adjacent motorized mounting walkways 11, and the two are fixedly connected with their upper surfaces flush, together forming the assembly area.

[0030] The elongated design of the electric installation platform 11 greatly reduces the weight of the entire installation platform 11. When the platform moves, it is only necessary to control the electric installation platform 11 of each elongated structure to move forward, which effectively overcomes the problem of slow platform movement caused by the overall heavy installation platform and greatly improves construction efficiency.

[0031] More preferably, the installation platform 1 also includes a transport trolley A13, an auxiliary installation gantry 14, and a step 15. The transport trolley A13 is positioned in the assembly area, and two C-shaped tracks are provided above the assembly area, allowing the transport trolley A13 to move along the C-shaped tracks within the assembly area (e.g., ...). Figure 2 This enables precise delivery of photovoltaic module components from external transportation locations to various assembly platforms 12.

[0032] The auxiliary installation gantry 14 is spanned across two adjacent motorized installation walkways 11, with its bottom ends supported on tracks on the two walkways 11, allowing it to move longitudinally along the tracks. After the photovoltaic modules on the assembly platform 12 are assembled into a single unit, the auxiliary installation gantry 14 precisely lifts the entire assembly above the truss 4 for installation and fixation. The auxiliary installation gantry 14 significantly improves the installation efficiency for construction workers. A footboard 15 is located at the rear end of the area between the two adjacent motorized installation walkways 11, with the two fixedly connected and their upper surfaces flush, providing a platform for construction workers to operate the equipment. Example 2

[0033] like Figure 3-4 This embodiment is basically the same as the first embodiment. Furthermore, the marine photovoltaic integrated installation system also includes a hoisting platform 2 placed on the marine truss 4.

[0034] The hoisting platform 2 includes a motorized transport walkway 21 longitudinally mounted on the offshore truss 4. The tail end of the motorized transport walkway 21 is connected to the head end of a portion of the motorized installation walkway 11. During construction, photovoltaic module components hoisted from the outside onto the motorized transport walkway 21 can be transported to the assembly platform 12 using transport equipment on the motorized transport walkway 21. A traveling device A (with the same structure as the traveling device below the motorized installation walkway 11) is installed at the bottom of the motorized transport walkway 21, enabling it to move forward together with the motorized installation walkway 11 on the offshore truss 4. The installation of the motorized transport walkway 21 improves the efficiency of transporting photovoltaic module components to the assembly platform 12.

[0035] To enable the marine photovoltaic integrated installation system to simultaneously function as an installation platform for the marine truss, the lifting platform 2 also includes multiple electrically operated support walkways 22, multiple lifting devices 23, and a transverse transport plate 24. The electrically operated support walkways 22 are longitudinally arranged on the marine truss 4, located on both sides of the electrically operated transport walkway 21 and arranged parallel to it. The lifting devices 23 are mounted on the electrically operated support walkways 22; preferably, the lifting devices 23 are monorail gantry cranes. The transverse transport plate 24 is located above the front ends of the electrically operated support walkways 22 and the electrically operated transport walkway 21 and is fixedly connected to both. A transport trolley B26 is mounted on the transverse transport plate 24. More preferably, to ensure that the lifting platform 2 can maintain balance on the marine truss 4, the lifting platform 2 also includes an electrically operated balancing walkway 25. The electrically operated balancing walkway 25 is located between two adjacent electrically operated support walkways 22 (except where an electrically operated transport walkway 21 is located between two adjacent electrically operated support walkways 22), and its front end is located below the transverse transport plate 24 and is fixedly connected to it. Even better, the bottom of the electrically supported walkway 22 and the electrically balanced walkway 25 is provided with a traveling device B (this traveling device B has the same structure as the traveling device below the electrically installed walkway 11), which can move forward together with the electrically installed walkway 11 and the electrically transport walkway 21 on the marine truss 4.

[0036] Preferably, the electric transport platform 21, the electric support platform 22, and the electric balance platform 25 are all elongated structures.

[0037] During construction, the hoisting platform 2 is first placed on the offshore truss, and the tail end of the electric transport walkway 21 is connected to the head end of part of the electric installation walkway 11. Then, the photovoltaic module components are hoisted onto the electric transport walkway 21. Next, the photovoltaic module components are transported to the assembly platform 12 connected to the hoisting platform 2 using the transport equipment on the electric transport walkway 21. While transporting the photovoltaic module components, the segmented truss 4 is hoisted from the outside onto the transverse transport plate 24, and the segmented truss 4 is spliced ​​into a whole truss on the transverse transport plate 24. The hoisting equipment 23 is used to hoist the spliced ​​whole truss assembly to the top of the front row of photovoltaic piles and install and fix it. Example 3

[0038] like Figure 5 This embodiment is basically the same as embodiment two. However, it further adds an implementation scheme for an unloading platform 3 that needs to be placed on top of the offshore photovoltaic pile. The unloading platform 3 is located at the front end of the hoisting platform 2. The unloading platform 3 can hoist the truss 4 and photovoltaic module components onto the hoisting platform 2.

[0039] The unloading platform 3 includes two symmetrically arranged traveling mechanisms 31, column-supporting rail beams 32, supporting trusses 33, a construction platform 34, and a connecting truss 36 connecting the two supporting trusses. A lifting device 35 is also configured to facilitate material transport. Specifically, the traveling mechanism 31 is installed on top of the photovoltaic piles, serving as the platform's moving foundation; the column-supporting rail beams 32 are vertically fixed above the traveling mechanism 31; the supporting trusses 33 are erected on top of the column-supporting rail beams 32, with slide rails laid on their upper part; the lifting device 35 is a preferred single-beam double-trolley crane, bridging the slide rails of the two supporting trusses 33, and can move longitudinally along the slide rails; a construction platform 34 is set between the two column-supporting rail beams 32, providing a safe working space for personnel.

[0040] During construction, the unloading platform 3 is placed on top of the photovoltaic piles. The truss 4 on the transport ship is hoisted onto the transverse transport plate 24 on the hoisting platform 2 by the lifting equipment 35. The photovoltaic module components on the transport ship are then hoisted onto the electric transport walkway 21 on the hoisting platform 2.

[0041] This embodiment achieves automated transfer of truss 4 and photovoltaic module components through efficient collaboration between hoisting platform 2 and unloading platform 3, reducing manual intervention and improving construction efficiency. Example 4

[0042] like Figure 6-7 This embodiment, based on embodiments one, two, and three, provides an installation method for a marine photovoltaic integrated system, specifically including the following steps: (1) Platform positioning: The installation platform 1 and the hoisting platform 2 are hoisted to the predetermined position above the installed truss 4, and the unloading platform 3 is hoisted to the predetermined position on the top of the photovoltaic pile, ensuring that the unloading platform 3 is located at the front end of the hoisting platform 2; (2) Photovoltaic module installation: ① Position the transport ship carrying photovoltaic module components and truss 4 below the unloading platform 3; ② The photovoltaic module components are hoisted to the electric transport platform 21 by the lifting equipment 35 of the unloading platform 3; ③ Use the transport equipment on the electric transport platform 21 to transfer the photovoltaic module components to the assembly platform 12 connected to the hoisting platform 2; ④ The photovoltaic module components are distributed to each assembly platform 12 for assembly using the transport trolley A13; ⑤ The assembled photovoltaic module 6 is precisely positioned and installed onto the truss 4 using the auxiliary installation gantry 14; (3) Truss installation: ① Using the lifting equipment 35 of the unloading platform 3, the segmented trusses 4 on the transport ship are sequentially hoisted to the docking area of ​​the transverse transport plate 24 (i.e., the transverse transport plate 24 at the connection between the hoisting platform 2 and the unloading platform 1). ② The truss sections 4 are moved to their respective splicing positions on the transverse transport plate 24 by the transport trolley B26 on the transverse transport plate 24, and are then connected and fixed end to end according to the design requirements; ③ Using the hoisting equipment 23 of the hoisting platform 2, the assembled truss assembly is hoisted to the top of the front row of photovoltaic piles, and then the positioning is adjusted and the assembly is tightened. (4) Platform relocation: ① Control the walking mechanism 31 of the unloading platform 3 to move forward to the next work station; ② Synchronously control the walking devices of each electric walkway (11, 21, 22, 25) to move forward in coordination, so that the installation platform 1 and the hoisting platform 2 are positioned at the new work position; (5) Cyclic operation: Repeat steps (2)-(4) until the installation of all trusses 4 and photovoltaic modules 6 is completed.

[0043] It should be noted that installation steps (2) and (3) can be interchanged or performed simultaneously; the first end of this utility model refers to the end close to the unloading platform 3, and the tail end and rear end refer to the end far away from the unloading platform.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
