[0036] Due to its unique marine environment, offshore photovoltaic projects have extremely high requirements for construction. How to carry out construction efficiently and safely has become a key issue that needs to be solved urgently. Especially in the construction process of fixed pile-based offshore photovoltaics (i.e., photovoltaic panels are supported above the sea surface by pile foundations and photovoltaic brackets), the operation management of ship engines is particularly important, and safety hazards such as collisions must be avoided. In view of the complexity and challenges of offshore photovoltaic construction, we urgently need a new construction method to ensure a smooth construction process.

[0037] Based on this, the present disclosure provides a fixed pile foundation offshore photovoltaic water flow construction method, such as Figure 1 As shown, the construction method includes steps S11 to S120, wherein:

[0038] Step S110, dividing the offshore photovoltaic area into a plurality of construction areas distributed side by side, each of the construction areas having at least one side facing the sea, and different construction areas being adjacent to each other;

[0039] Step S120, different construction areas are synchronously subjected to flow construction, the construction direction of the construction area is directed from the center of the construction area to the periphery of the construction area, and the construction directions of adjacent construction areas are different.

[0040] like Figure 2 As shown, the multiple construction areas include a first construction area 1, a second construction area 2, and a third construction area 3. The length of the edge line of the first construction area 1 facing the sea is greater than the length of the edge line of the first construction area 1 not facing the sea; the length of the edge line of the second construction area 2 facing the sea is less than the length of the edge line of the first construction area 1 not facing the sea; the length of the edge line of the third construction area 3 facing the sea is greater than the length of the edge line of the first construction area 1 not facing the sea. The area of ​​the first construction area 1, the area of ​​the second construction area 2, and the area of ​​the third construction area 3 are different.

[0041] In some embodiments of the present disclosure, the flow construction method of the present disclosure may further include:

[0042] Step S130, assembling photovoltaic support members in the land area 5 to form a photovoltaic support; the land area 5 is connected to the first construction area 1 through the waterway 4;

[0043] Step S140, transporting the photovoltaic support to the first construction area 1 through the waterway 4;

[0044] Step S150: transporting the photovoltaic support to the third construction area 3 along the edge line of the first construction area 1 facing the sea.

[0045] The edge line of the first construction area 1 facing the sea is located on a side of the first construction area 1 close to the land area 5 .

[0046] The fixed pile foundation offshore photovoltaic flow construction method disclosed in the present invention divides the photovoltaic area 100 into a plurality of parallel and adjacent construction areas (including the first construction area 1, the second construction area 2 and the third construction area 3), and ensures that at least one side of each construction area is close to the sea, which can facilitate material transportation, reduce the difficulty of material handling, and facilitate rapid response and evacuation in emergency situations, and the construction safety is high; at the same time, the boundaries of the construction area are clear, which is convenient for efficient management and monitoring. At the same time, the first construction area 1 has a long seaward edge line, which is convenient for connection with the land area 5 through the waterway 4, providing convenience for the transportation of photovoltaic brackets.

[0047] By adopting a synchronous flow construction strategy, each construction area advances in an orderly manner from the center to the surrounding areas, and the construction directions of adjacent construction areas are different, which can reduce cross-operation between construction teams and fundamentally avoid construction conflicts, such as ship-machine collision and other safety hazards, thereby improving construction efficiency and reducing safety risks.

[0048] At the same time, the zoning construction strategy makes large-scale photovoltaic projects easy to manage. Each area can independently plan the construction process according to the actual situation, which can simplify the complexity of construction organization. In addition, the synchronous construction strategy ensures that all construction areas can be advanced synchronously, effectively avoiding the overall progress lag caused by local delays. The construction strategy in different directions of adjacent areas promotes the flexible scheduling and optimal allocation of construction resources, allowing personnel, machinery, etc. to flow efficiently between different areas, avoiding idleness and waste of resources, and further improving construction efficiency and economic benefits.

[0049] The following is a detailed description of the various steps and specific details of the fixed pile foundation offshore photovoltaic flow water construction method in the embodiment of the present disclosure:

[0050] like Figure 1 As shown, in step S110, the offshore photovoltaic area 100 is divided into a plurality of construction areas distributed side by side, each construction area is adjacent to the sea on at least one side, and different construction areas are adjacent to each other.

[0051] The offshore photovoltaic area 100 can be determined according to the geographical features of the sea area, water depth, tidal conditions, wind and wave conditions, and the layout requirements of the photovoltaic array. The photovoltaic area 100 can be rectangular, polygonal, or irregular in shape, and is not specifically limited here. The area of ​​the photovoltaic area 100 can be 5km 2 ~8km 2 There is no special limitation on the area of ​​the photovoltaic area 100. The photovoltaic area 100 can be 2.0 km away from the coast at its shortest distance and 6.5 km away from the coast at its farthest distance. The water depth of the photovoltaic area 100 is about 8m to 12m.

[0052] Please continue to see Figure 2As shown, the photovoltaic area 100 can be divided into a plurality of construction areas arranged side by side, and each construction area is at least one side facing the sea. With such a design, the ocean can be used as a natural logistics channel to facilitate the transportation and installation of large equipment (such as crane ships or pile-driving ships, etc.), materials, and photovoltaic brackets, and can also effectively reduce the cost and risk of land transportation. The construction area on the sea side often serves as the logistics hub of the entire project, and undertakes the important tasks of docking with the land area 5 and the distribution of materials; at the same time, it can also ensure that the ship and machinery can be smoothly withdrawn after the construction is completed.

[0053] In an exemplary embodiment of the present disclosure, different construction areas are adjacent to each other to ensure that each construction area can work independently and cooperate with each other. Buffer zones or shared channels can be set between adjacent construction areas to facilitate the flexible transfer of construction teams, equipment, and materials between different areas, while avoiding construction conflicts and resource competition. This not only helps to improve construction efficiency, but also enhances the overall coordination and controllability of the project.

[0054] In an exemplary embodiment of the present disclosure, please continue to refer to Figure 2 As shown, the multiple construction areas may include a first construction area 1, a second construction area 2 and a third construction area 3, wherein:

[0055] The first construction area 1 can serve as the logistics hub and starting point of the entire offshore photovoltaic system. Its edge line facing the sea is relatively long. For example, the length of the edge line facing the sea in the first construction area 1 is greater than the length of the edge line not facing the sea in the first construction area 1, so that large equipment, photovoltaic brackets and construction materials can be smoothly transported directly to the construction site by sea. At the same time, the long edge line facing the sea provides a wide working space for the construction team, which is convenient for the rapid development and efficient advancement of construction activities.

[0056] Please continue to see Figure 2 As shown, compared with the first construction area 1, the length of the seaward edge line of the second construction area 2 is relatively small. For example, the length of the seaward edge line in the second construction area 2 is smaller than the length of the non-seaward edge line in the first construction area 1, and the seaward edge line in the second construction area 2 is connected to the seaward edge line in the first construction area 1. The second construction area 2 is mainly used in the finishing stage of the project construction. Its smaller seaward edge line reduces direct contact with the outside world and reduces external interference during the construction process, which is conducive to the construction team to concentrate on completing the final finishing work (for example, photovoltaic panel installation). At the same time, the non-seaward edge line provides a relatively closed working environment for the construction team, which helps to improve construction efficiency and safety.

[0057] Please continue to see Figure 2As shown, the third construction area 3 adjacent to the second construction area 2 also has a long seaward edge line. For example, the length of the seaward edge line in the third construction area 3 is greater than the length of the non-seaward edge line in the first construction area 1. Moreover, the seaward edge line in the third construction area 3 is connected to the seaward edge line in the first construction area 1 and the seaward edge line in the second construction area 2. This layout not only maintains the continuity of the logistics channel, allowing materials to flow quickly between the two construction areas, but also further enhances the flexibility and coordination of construction activities in the third construction area 3.

[0058] In some embodiments of the present disclosure, the area of ​​the first construction area 1, the area of ​​the second construction area 2, and the area of ​​the third construction area 3 can be set according to different operation requirements, that is, when the first construction area 1, the second construction area 2, and the third construction area 3 respectively carry different operation tasks, the areas of the first construction area 1, the second construction area 2, and the third construction area 3 are different. For example, the first construction area 1 can be used to set up a substation and lay a collector line; the second construction area 2 can be used to transport photovoltaic panels and perform performance parameter testing on photovoltaic panels; the third construction area 3 can be used to install photovoltaic brackets and lay cables.

[0059] In an exemplary embodiment of the present disclosure, please continue to refer to Figure 2 As shown, the first construction area 1 includes a first inner line 11, a second inner line 12 and a first edge line 13. The first inner line 11 and the second inner line 12 can both be straight lines. One end of the first inner line 11 is connected to one end of the second inner line 12, and the first inner line 11 and the second inner line 12 are not colinear; for example, the first inner line 11 and the second inner line 12 can be perpendicular to each other. The first edge line 13 can be a broken line, and the first edge line 13 is connected between the end of the first inner line 11 away from the second inner line 12 and the end of the second inner line 12 away from the first inner line 11. The first inner line 11, the second inner line 12 and the first edge line 13 together enclose the first construction area 1, wherein the first edge line 13 is distributed near the sea, and some areas of the first inner line 11 and the second inner line 12 are adjacent to the second construction area 2. In some embodiments of the present disclosure, the angle between the first inner line 11 and the second inner line 12 can be defined as an inner angle, and the first edge line 13 is connected to the side away from the inner angle.

[0060] Please continue to see Figure 2As shown, the second construction area 2 is composed of the third inner line 21, the fourth inner line 22, the fifth inner line 23, the sixth inner line 24 and the second edge line 25 connected end to end in sequence. The third inner line 21, the fourth inner line 22, the fifth inner line 23, the sixth inner line 24 and the second edge line 25 can all be straight lines, and no two adjacent lines are collinear. The third inner line 21 and the first inner line 11 are parallel and adjacently arranged, and the space formed between them is the first channel 10, which can be used for logistics transportation or personnel passage during the construction process; the fourth inner line 22 and the second inner line 12 can also be parallel and adjacently arranged, and the length of the fourth inner line 22 can be less than the length of the second inner line 12. The interval between the fourth inner line 22 and the second inner line 12 constitutes the second channel 20, which can also be used for logistics transportation or personnel passage within the construction area.

[0061] In an exemplary embodiment of the present disclosure, when the first inner line 11 is perpendicular to the second inner line 12, the third inner line 21 may also be perpendicular to the fourth inner line 22. At the same time, the fifth inner line 23 may be perpendicular to the fourth inner line 22, and the fifth inner line 23 is located on the side of the fourth inner line 22 away from the second inner line 12. The sixth inner line 24 may be perpendicular to the fifth inner line 23, that is, the sixth inner line 24 may be distributed parallel to the fourth inner line 22. The second edge line 25 is connected between the third inner line 21 and the sixth inner line 24, and the second edge line 25 is distributed near the sea. At the same time, the third inner line 21 and the fourth inner line 22 are both adjacent to the first construction area 1, and the fifth inner line 23 and the sixth inner line 24 are both adjacent to the third construction area 3.

[0062] The second edge line 25 serves as the closed boundary of the entire second construction area 2. It can be a straight line, a broken line or a curve, as long as it can adapt to the topography and work requirements of the construction site. The second edge line 25 is connected between the end of the sixth inner line 24 away from the fifth inner line 23 and the end of the third inner line 21 away from the fourth inner line 22, thereby enclosing a complete and functionally clear second construction area 2 together with the remaining inner lines.

[0063] In some embodiments of the present disclosure, in order to optimize construction efficiency and management, the width, position of the first channel 10 and the second channel 20 and the protective measures on both sides of the channels can be adjusted according to the actual needs of the construction activities. For example, safety isolation fences, signs or lighting facilities can be added to ensure traffic safety and smooth operations in the construction area.

[0064] Please continue to see Figure 2As shown, the third construction area 3 includes a third edge line 34 and the seventh inner line 31, the eighth inner line 32, and the ninth inner line 33 connected in sequence, that is, the third edge line 34 and the closely connected seventh inner line 31, the eighth inner line 32, and the ninth inner line 33 together enclose the third construction area 3. Among them, the seventh inner line 31 is parallel to and adjacent to the sixth inner line 24, and the third channel 30 is between the seventh inner line 31 and the sixth inner line 24; the third channel 30 can be used for material transportation and personnel flow during construction, ensuring efficient logistics and safe passage of personnel. The width of the third channel 30 can be matched with the needs of construction activities, and the width of the third channel 30 is not specifically limited here. The eighth inner line 32 is parallel to and adjacent to the fifth inner line 23, and the fourth channel 40 is between the fifth inner line 23 and the eighth inner line 32; the fourth channel 40 also bears the function of traffic diversion in the construction area, which can be convenient for alleviating traffic pressure that may occur during construction. In order to further improve the safety and efficiency of the channel, necessary traffic signs, safety fences and lighting systems can be installed on both sides of the channel to ensure smooth construction activities.

[0065] The ninth inner wire 33 is arranged in the same line as the fourth inner wire 22 to improve space utilization. The ninth inner wire 33 can be arranged parallel to and adjacent to the second inner wire 12, and the fifth channel 50 is between the second inner wire 12 and the ninth inner wire 33; the establishment of the fifth channel 50 provides another important path for horizontal communication within the construction area, thereby enhancing the connectivity and flexibility within the construction area.

[0066] The third edge line 34 is distributed along the sea. The third edge line 34 serves as the outer boundary of the third construction area 3. Its shape can be flexibly adjusted according to the specific terrain, geological conditions and construction requirements of the construction site. Whether it is a straight line, a broken line or a curve shape, it is intended to ensure the safe closure and efficient management of the construction area. The third edge line 34 is connected between the seventh inner line 31 and the ninth inner line 33 (for example, the third edge line 34 is connected between the end of the seventh inner line 31 away from the eighth inner line 32 and the end of the ninth inner line 33 away from the eighth inner line 32), and cooperates with each inner line to enclose the third construction area 3.

[0067] In addition, in order to further optimize the construction process and improve management efficiency, the width, location and protection measures of the passages in the third construction area 3 can be dynamically adjusted according to the construction progress and actual conditions. For example, temporary roads can be added in the third construction area 3, the layout of the passages can be adjusted, and safety protection measures can be strengthened to ensure that construction activities are carried out smoothly in a safe and efficient environment.

[0068] It should be noted that the first edge line 13 (i.e., the edge line facing the sea in the first construction area 1), the second edge line 25 (i.e., the edge line facing the sea in the second construction area 2) and the third edge line 34 (i.e., the edge line facing the sea in the third construction area 3) can jointly enclose the photovoltaic area 100 disclosed herein.

[0069] like Figure 1 As shown, in step S120, different construction areas are synchronously subjected to flow construction, the construction direction of the construction area is from the center of the construction area to the surroundings of the construction area, and the construction directions of adjacent construction areas are different.

[0070] Flow construction can be carried out simultaneously in different construction areas. For example, flow construction can be carried out simultaneously in the first construction area 1, the second construction area 2 and the third construction area 3. During this process, each construction area can be advanced from the center to the surrounding areas. Since the construction directions of adjacent construction areas are different, it not only reduces the cross-operation between construction teams and avoids construction conflicts (for example, ship-machine collision), but also improves construction efficiency and reduces safety risks. At the same time, zoning construction makes large-scale projects easier to manage. Each area can plan the construction process independently, reducing the complexity of construction organization. In addition, the synchronous construction strategy ensures that all areas are advanced synchronously, avoiding overall progress lags due to local delays. Construction strategies in different directions promote flexible scheduling and optimal allocation of resources. Personnel and machinery can flow efficiently between different areas, avoiding idle resources.

[0071] In some embodiments of the present disclosure, the flow construction may include at least equipment installation, photovoltaic bracket installation, cable laying, photovoltaic panel installation, etc. The simultaneous flow construction in different construction areas (i.e., step S120) may include steps S210 to S240, such as Figure 3 As shown, where:

[0072] Step S210, installing the equipment in the first construction area, wherein the equipment installation includes setting up a substation and laying a collector line.

[0073] The substation infrastructure components can be transported to the predetermined location. Due to the special offshore environment, floating cranes or offshore cranes are required for precise lifting, and divers are required to fix and inspect the underwater infrastructure components. After the substation infrastructure components are stabilized, the main equipment of the substation is installed. The main equipment may include transformers, switchgear, control systems, etc. It should be noted that these equipment must be treated with anti-corrosion to adapt to the marine environment.

[0074] The collection line can be laid using ships and professional offshore cable laying equipment. The line needs to be laid along a preset seabed or sea surface path, and buoys or seabed markers are set to mark the line direction. Cable traction and fixing devices can be used during the laying process to ensure the stability and safety of the cable in the marine environment.

[0075] Step S220, transporting the photovoltaic panels to the second construction area, and inspecting performance parameters of the photovoltaic panels in the second construction area.

[0076] The photovoltaic panels can be transported from the land area 5 or the warehouse to the second construction area 2 by a transport ship. Subsequently, the staff can be organized to check the performance parameters of the photovoltaic panels and record the test results. The performance parameters may include the power, voltage, current, efficiency, and waterproof performance of the photovoltaic panels. Photovoltaic panels that do not meet the requirements must be marked and isolated in time to avoid flowing into the subsequent installation links.

[0077] Step S230, installing the photovoltaic support in the third construction area and laying the cable.

[0078] The installation location and layout of the photovoltaic bracket can be determined according to the design drawings and actual site conditions. During the installation process, professional offshore construction equipment and tools, such as offshore cranes, screwdrivers, wrenches, etc., must be used, and strict installation specifications and operating procedures must be followed. After the photovoltaic bracket is installed, a stability check is required to ensure that the photovoltaic bracket can withstand the weight of the photovoltaic panel and the test of the marine environment.

[0079] After the photovoltaic bracket is installed, you can start laying cables. The cables need to be laid along the bracket or the preset path and fixed with cable clamps or fixing devices. During the laying process, cable joints and junction boxes need to be set up, and the insulation and conductivity of the cables need to be ensured to be good.

[0080] Step S240, installing the photovoltaic panel on the photovoltaic bracket after the photovoltaic bracket and the cable are laid in the third construction area.

[0081] After the photovoltaic brackets and cables are laid, the photovoltaic panel installation phase begins. For example, the installation order and location of the photovoltaic panels can be determined based on the design drawings and the performance parameters of the photovoltaic panels. Then, the photovoltaic panels are hoisted one by one onto the photovoltaic brackets using offshore cranes or lifting equipment, and fixed using tools such as screwdrivers and wrenches. During the installation process, it is necessary to ensure that the connection between the photovoltaic panel and the photovoltaic bracket is firm and reliable, and adjust the angle and orientation of the photovoltaic panel to maximize the use of solar energy.

[0082] After the photovoltaic panels are installed, electrical connections and commissioning are required. For example, the photovoltaic panels can be connected to cables and necessary protection devices and monitoring systems can be set up. Finally, the entire photovoltaic system is fully inspected and tested to ensure that the system can operate normally and meet the design requirements.

[0083] In an exemplary embodiment of the present disclosure, Figure 4 As shown, the fixed pile foundation offshore photovoltaic flowing water construction method disclosed in the present invention may also include steps S130 to S150, wherein:

[0084] Step S130, assembling photovoltaic support members in a land area to form a photovoltaic support; the land area is connected to the first construction area through a waterway.

[0085] A land area 5 close to the photovoltaic area 100 and with convenient transportation can be selected on the coast as an assembly site. The area has a flat terrain and no obstructions, which is convenient for the entry and exit and operation of large equipment and materials. Considering the convenience of subsequent transportation, the site of the land area 5 can be selected as close to the entrance of the waterway 4 as possible.

[0086] Photovoltaic supports (e.g., support grids, support beams, support rods, fixings and connectors, etc.) can be assembled in the land area 5 to form a photovoltaic support for supporting photovoltaic panels. The land area 5 can be planned with clear logistics channels, assembly areas, storage areas and temporary facilities areas to ensure that the functional areas do not interfere with each other and the process is smooth. The materials such as the support grids, support beams, support rods, fixings and connectors required for the photovoltaic supports can be transported to the land area 5 in advance and stored in categories as needed. The support grids, support beams, support rods, fixings and connectors are assembled according to the design drawings to form a photovoltaic support.

[0087] It should be noted that the process of assembling photovoltaic support members in the land area 5 can be carried out simultaneously with the flow construction process in the first construction area 1, the second construction area 2 and the third construction area 3, thus realizing efficient use of construction resources and rapid advancement of construction progress. The land area 5 and each construction area can ensure smooth construction and timely resolution of problems through effective communication and coordination mechanisms.

[0088] Step S140: transport the photovoltaic support to the first construction area through the waterway.

[0089] The edge line of the first construction area 1 facing the sea (i.e., the first edge line 13) is located on the side of the first construction area 1 close to the land area 5, that is, the first edge line 13 is close to the boundary of the ocean, and the assembled photovoltaic brackets in the land area 5 can be transported to the first edge line 13 of the first construction area 1 through the waterway 4. The waterway 4 can be a straight waterway 4, which can shorten the transportation distance to the maximum extent and improve the logistics speed; and the straight design helps to simplify the navigation route, reduce the difficulty of navigation, and thus improve the safety of transportation.

[0090] Step S150: transporting the photovoltaic support to the third construction area along the edge line of the first construction area facing the sea.

[0091] After arriving at the first construction area 1 , the photovoltaic support can be transported to the third construction area 3 along the first edge line 13 .
