Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a pile-based offshore photovoltaic installation system. Background Art

[0002] Pile-based offshore photovoltaic is a system that uses marine resources to generate renewable energy. By installing photovoltaic modules on offshore piles, the effective use of solar energy can be achieved. Without occupying land resources, the vast ocean space can be used for clean energy production. The pile foundation is usually made of steel or concrete and can withstand the impact of waves, wind and tides.

[0003] Pile-based offshore photovoltaic systems are usually built in areas close to the coastline, where the water depth is shallow and the seabed geological conditions are relatively easy to carry out piling operations. Photovoltaic modules are usually installed by hoisting operations. For example, a method disclosed in Chinese patent application CN117552396A is: pre-assemble the photovoltaic unit in the pre-assembly area; then use a second crane on the construction ship to hoist the photovoltaic unit onto the pile foundation where the piling operation has been completed to complete the photovoltaic installation.

[0004] Although photovoltaic modules are lightweight, they still require high lifting equipment due to their large coverage area. Especially when installing over a large area, they face problems of low efficiency and high cost. In particular, due to the limited distance between pile foundations, the installation ship cannot enter between the pile foundations for installation. If some photovoltaic modules are damaged later, replacement work will also face great difficulties. Summary of the invention

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "electrically connected" should be understood in a broad sense. For example, it can be a fixed electrical connection, a detachable electrical connection, or an integral electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the implementation method, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0050] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0052] In view of the problems of low efficiency and high cost when carrying out large-area photovoltaic module hoisting and installation operations, an embodiment of the present invention provides a pile-based offshore photovoltaic installation system. Figures 1 to 3 As shown, the pile-based offshore photovoltaic installation system provided in this embodiment includes a pile foundation module, a transportation module and an installation module.

[0053] like Figures 1 to 5As shown, the pile foundation module includes multiple groups of offshore pile foundations 11 distributed at intervals. The offshore pile foundation 11 can be a tubular structure supported by steel and fixed to the seabed by vibration or impact; the pile foundation 11 can also be a concrete pile, or a composite pile made of reinforced concrete, and the concrete pile or the composite pile is prefabricated in advance or cast on site. No further restrictions are imposed on the specific material, shape and number of the offshore pile foundation 11. In one or more embodiments of the present invention, the heights of the multiple groups of offshore pile foundations 11 are the same. The multiple groups of offshore pile foundations 11 are distributed at equal intervals.

[0054] A continuous installation slideway 12 and a traction slideway 13 are laid on the top of multiple groups of offshore pile foundations 11. Specifically, a truss 15 is arranged on the top of the offshore pile foundation 11. The truss 15 is composed of a plurality of triangular units. The design of the triangular units enables the truss 15 to remain stable and not deform when subjected to force. The installation slideway 12 and the traction slideway 13 are laid on the top of the truss 15. The installation slideway 12 and the traction slideway 13 are made of corrosion-resistant materials, such as coated steel with a corrosion-resistant coating.

[0055] The installation slideway 12 and the traction slideway 13 extend along the first direction D1. Figures 1 to 3 As shown, multiple groups of offshore pile foundations 11 are distributed in a linear manner. Corresponding to the distribution direction of the offshore pile foundations 11, the first direction D1 is the distribution direction of the multiple groups of offshore pile foundations 11. The traction slide 13 is used to guide the traction motor 14 to slide, and the traction motor 14 is used to drive the photovoltaic unit 100 to slide along the installation slide 12.

[0056] The transport module includes a transport ship 21. When the photovoltaic unit 100 is installed, the transport ship 21 is positioned at one end of the pile foundation module.

[0057] The transport ship 21 is provided with a photovoltaic unit rack 22. A mounting bracket 23 is provided in any layer of the photovoltaic unit rack 22. A connecting slide 24 is provided on the mounting bracket 23. The connecting slide 24 extends along the first direction D1. When preparing for installation, a slider under the photovoltaic unit 100 slides in from one end of the connecting slide 24 so that the photovoltaic unit 100 is slidably installed in the photovoltaic unit rack 22.

[0058] In one or more embodiments of the present invention, each layer of the photovoltaic unit rack 22 is slidably mounted with a photovoltaic unit 100, so that the transport ship 21 has a maximum carrying capacity during a single installation, thereby improving the installation efficiency. The photovoltaic unit 100 slidably mounted in the photovoltaic unit rack 22 can be further fixed by a cable or a limiting structure to maintain stability during marine transportation. After the photovoltaic unit 100 is loaded into each layer of the photovoltaic unit rack 22, the transport ship 21 moves to the sea area near the pile foundation module and is positioned at one end of the pile foundation module.

[0059] When the transport ship 21 is positioned at one end of the pile foundation module, the installation module is located between the pile foundation module and the transport module. The installation module includes a transfer device 31 , a lifting device 32 and a motion stabilization device 33 .

[0060] The transfer device 31 has a straight arm section 35 extending outward along a second direction D2. The second direction D2 is perpendicular to the first direction D1. The straight arm section 35 is provided with a pair of limit blocks 34 that can move along the straight arm section 35 and extend upward.

[0061] The lifting device 32 drives the transfer device 31 to rise and fall along the height direction of the photovoltaic unit rack 22. The lifting device 32 can slide along the moving slide 25 provided on the transport ship 21. The moving slide 25 extends along the second direction D2.

[0062] The motion stabilizing device 33 is disposed between the transfer device 31 and the lifting device 32 to adjust the height of the transfer device 31 .

[0063] During installation, the lifting device 32 adjusts the height of the transfer device 31 so that the transfer device 31 is aligned with any layer of the photovoltaic unit shelf 22. The lifting device 32 moves toward the photovoltaic unit shelf 22 along the moving slide 25. The straight arm section 35 extends below the mounting bracket 23, and the lifting device 32 adjusts the height of the transfer device 31 so that the mounting bracket 23 is embedded between the limit blocks 34. The lifting device 32 adjusts the height of the transfer device 31 again, and the transfer device 31 lifts the mounting bracket 23 upward, so that the mounting bracket 23 is separated from the photovoltaic unit shelf 22. The limit blocks 34 are further driven to move along the straight arm section 35 in a direction away from the photovoltaic unit shelf 22, and the photovoltaic unit 100 is taken out of the photovoltaic unit shelf 22. The lifting device 32 adjusts the height of the transfer device 31, and the motion stabilizing device 33 adjusts the angle of the transfer device 31 so that the mounting slide 12 is aligned with the slider below the photovoltaic unit 100 supported by the transfer device 31. The slider below the photovoltaic unit 100 and the installation slide 12 are slidably matched, and the traction motor 14 is connected to the photovoltaic unit 100 through the traction cable, driving the photovoltaic unit 100 into the installation slide 12, and the traction motor 14 further pulls the photovoltaic unit 100 to slide to the installation position.

[0064] The pile-based offshore photovoltaic installation system provided by the present invention does not require the use of lifting equipment and can be operated at a relatively low height, thereby significantly reducing safety risks and reducing the occurrence of accidents. The pile-based offshore photovoltaic installation system adopts a modular design, and the pile foundation module, the transportation module and the installation module can cooperate with each other and move the photovoltaic unit to the installation position, realizing automated placement and movement, effectively reducing manual intervention, improving installation efficiency, and shortening installation time. It is particularly suitable for the installation of large-area photovoltaic panels.

[0065] like Fig.10 and Fig.11 As shown, in one or more embodiments of the present invention, the transfer device 31 includes symmetrically arranged straight arm sections 35. Each straight arm section 35 is provided with a pair of limit blocks 34 that can move along the straight arm section 35 and extend upward. The movement of the limit blocks 34 along the straight arm section 35 is driven by a crawler drive unit. The crawler drive unit includes two crawlers, two sets of synchronous pulleys 38, an intermediate transmission shaft 37 and a crawler drive motor 36. The longitudinal cross-section of each straight arm section 35 is designed to be runway-shaped, and the two straight arm sections 35 are used to support the crawlers and play a guiding role, and are also used to accommodate the synchronous pulleys 38. The intermediate transmission shaft 37 is arranged between the two straight arm sections 35, and a set of synchronous pulleys 38 are respectively arranged at both ends of the intermediate transmission shaft 37. The crawler drive motor 36 is arranged on one side of one of the straight arm sections 35, and the intermediate transmission shaft 37 can distribute the power of the crawler drive motor 36 to the synchronous pulleys 38 on both sides to ensure that the crawlers on both sides move synchronously, and further make the limit blocks 34 move along the straight arm section 35.

[0066] In one or more embodiments of the present invention, the motion stabilizing device 33 includes a fixed plate 331 and a driving cylinder 332. The transfer device 31 is mounted on the fixed plate 331, and the driving cylinders 332 are evenly distributed below the fixed plate 331. The plurality of driving cylinders 332 are independently extended and retracted to drive the fixed plate 331 to rotate and adjust the angle of the transfer device 31. Fig.10 and Fig.11 As shown, three driving cylinders 332 may be provided in the motion stabilizing device 33, and the three driving cylinders 332 are distributed in an equilateral triangle. The motion stabilizing device 33 may also realize motion compensation to offset the fluctuation of the transport ship 21 caused by waves.

[0067] In one or more embodiments of the present invention, the lifting device 32 includes a base 321 and a lifting platform 322. The motion stabilizing device 33 is fixedly connected to the top of the lifting platform 322, and the lifting platform 322 is installed on the base 321. The base 321 can drive the lifting platform 322 to slide along the moving slide 25. The lifting platform 322 can be a hydraulic lifting platform 322.

[0068] like Figure 6 As shown, in one or more embodiments of the present invention, a plurality of installation slideways 12 are laid on the top of the plurality of offshore pile foundations 11 in a continuous and mutually parallel manner. Each installation slideway 12 includes a continuous installation slideway body 121 and an installation slideway end 122, and the installation slideway end 122 tapers to form an angle less than 90°, which can also be called a "tip", and the angle can accurately position the slider under the photovoltaic unit 100, so as to facilitate the alignment and connection of the installation slideway 12 and the slider.

[0069] like Figure 8 and Fig. 9 As shown, in one or more embodiments of the present invention, a shelf slide 221 is fixedly provided in each layer of the photovoltaic unit shelf 22. The shelf slide 221 extends along the second direction D2, and the lower corners of the mounting bracket 23 respectively form limiting edges 231. The limiting edges 231 are arranged corresponding to the shelf slide 221, and the two overlap in the height direction of the shelf of the photovoltaic unit 100. Through the cooperation of the limiting edge 231 and the shelf slide 221, the mounting bracket 23 can only move upward to separate from the shelf slide 221. This overlapping structure can also ensure that during installation or transportation, the mounting bracket 23 will not move in other directions and maintain sufficient stability.

[0070] The pile-based offshore photovoltaic installation system provided by the present invention is particularly suitable for the installation of photovoltaic panels. That is, the photovoltaic unit 100 is a rectangular photovoltaic panel. Rectangular photovoltaic panels are easy to manufacture, install and connect. In one or more embodiments of the present invention, two connecting slideways 24 are arranged in parallel on the upper side of the mounting bracket 23 to match the photovoltaic panel.

[0071] like Figure 7 As shown, a first slider group 101 and a second slider group 102 are arranged below the photovoltaic panel as the photovoltaic unit 100. The first slider group 101 includes at least two sliders, and the two sliders in the first slider group 101 are spaced apart along the first direction D1 (for example, the length direction of the photovoltaic panel, that is, the distribution direction of the multiple groups of offshore pile foundations 11), and the two sliders in the second slider group 102 are also spaced apart along the first direction D1. The first slider group 101 and the second slider group 102 are spaced apart and parallel in the second direction D2 (for example, the width direction of the photovoltaic panel), and one of the two connecting slideways 24 passes through the two sliders in the first slider group 101, and the other passes through the two sliders in the second slider group 102.

[0072] On one side of the installation slide 12, the traction motor 14 is connected to the photovoltaic unit 100 through a traction cable. The two slides of the installation slide 12 pass through the two sliders in the first slider group 101 and the two sliders in the second slider group 102 respectively. The traction motor 14 pulls the photovoltaic unit 100 to slide to the installation position.

[0073] For example, Figures 1 to 5 As shown, two groups of installation slideways 12 are symmetrically laid on the top of the multiple groups of offshore pile foundations 11, and the traction slideway 13 is located between the two groups of installation slideways 12. Each group of installation slideways 12 can be installed with a photovoltaic unit 100. The traction motor 14 located between the two groups of installation slideways 12 is connected to the two photovoltaic units 100 through the traction cable, that is, the traction motor 14 can simultaneously pull the photovoltaic unit 100 to slide to the installation position, thereby improving the installation efficiency.

[0074] The second aspect of the present invention provides a pile-based offshore photovoltaic installation method, which uses the pile-based offshore photovoltaic system described in detail in the above embodiment. The pile-based offshore photovoltaic installation method includes the following steps.

[0075] Align the slider under the photovoltaic unit 100 to be installed with the connecting slide 24 on the mounting bracket 23 in the photovoltaic unit frame 22, and slide the slider into one end of the connecting slide 24 so that the photovoltaic unit 100 to be installed is slidably installed in the photovoltaic unit frame 22.

[0076] The transport vessel 21 is positioned at one end of the pile foundation module.

[0077] The lifting device 32 adjusts the height of the transfer device 31 so that the transfer device 31 is aligned with any layer of the photovoltaic unit shelf 22, and the straight arm section 35 extends under the mounting bracket 23. The lifting device 32 adjusts the height of the transfer device 31 so that the mounting bracket 23 is embedded between the limit blocks 34; the lifting device 32 adjusts the height of the transfer device 31 again, and the transfer device 31 lifts the mounting bracket 23 upward, so that the mounting bracket 23 is separated from the photovoltaic unit shelf 22; the limit blocks 34 are driven to move along the straight arm section 35 in a direction away from the photovoltaic unit shelf 22 to take out the photovoltaic unit 100 from the photovoltaic unit shelf 22; the lifting device 32 adjusts the height of the transfer device 31, and the motion stabilizing device 33 adjusts the angle of the transfer device 31 so that the installation slide 12 is aligned with the slider under the photovoltaic unit 100 supported by the transfer device 31; the slider under the photovoltaic unit 100 slides with the installation slide 12.

[0078] The traction motor 14 and the photovoltaic unit 100 are connected by a traction cable, driving the photovoltaic unit 100 to enter the installation slide 12, and the traction photovoltaic unit 100 slides to the installation position.

[0079] The pile-based offshore photovoltaic installation method provided by the present invention can effectively improve the installation efficiency of large-area photovoltaic panels.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents.
