Description

Technical Field

[0001] This application relates to the field of offshore photovoltaic technology, and more specifically, to an installation facility for offshore photovoltaic pre-assembly. Background Technology

[0002] Offshore photovoltaics is a renewable energy technology that installs photovoltaic power generation systems on the surface of the ocean. It features high power generation, less land occupation, and easy integration with other industries. Offshore photovoltaics converts solar energy into electricity by building photovoltaic power stations on the sea. Compared with traditional ground-based photovoltaic power stations, offshore photovoltaic power stations do not occupy valuable land resources, and because the sea surface is open and there are few obstructions, they can make fuller use of solar energy resources and improve power generation efficiency.

[0003] During the construction of offshore solar power, the steel support structure, solar modules, and some electrical equipment are typically pre-assembled on land before being lifted to the sea and connected to the foundation. However, the pre-assembly process on land is frequently affected by severe weather, causing delays or even work stoppages, thus reducing the construction efficiency of offshore solar power pre-assembly.

[0004] Therefore, how to improve the construction efficiency of offshore photovoltaic pre-assembly has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an installation workshop for offshore photovoltaic pre-assembly in order to improve the construction efficiency of offshore photovoltaic pre-assembly.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An installation facility for pre-assembly of offshore photovoltaic systems includes:

[0008] The main body of the factory building includes a frame structure and a cover plate disposed on top of the frame structure, so that the frame structure and the cover plate enclose an installation space for pre-assembly of offshore photovoltaics.

[0009] The hoisting equipment, located in the installation space, is used to hoist the parts required for the pre-assembly of offshore photovoltaic systems.

[0010] A mobile device is installed at the bottom of the frame structure, and the mobile device is used to move the main body of the factory building.

[0011] Optionally, in the above-mentioned installation workshop, the frame structure includes two rows of parallel lattice columns and lattice beams connected to the top of the lattice columns. The lattice beams include a first lattice beam and a second lattice beam. Each row of lattice columns is connected by the first lattice beam, and the two rows of lattice columns are connected at their ends by the second lattice beam.

[0012] Optionally, in the aforementioned installation workshop, each row of lattice columns is provided with a support beam on the side facing the installation space, and the hoisting equipment is movably mounted on two of the support beams.

[0013] Optionally, in the aforementioned installation workshop, the hoisting equipment includes a track beam movable along the support beam and an electric hoist movable along the track beam. The track beam is arranged perpendicular to the support beam, and the electric hoist is used to hoist the parts required for the pre-assembly of offshore photovoltaic systems.

[0014] Optionally, in the above-mentioned installation workshop, the moving device includes a pulley disposed at the bottom of the lattice column and a slide rail cooperating with the pulley. The pulley can move along the slide rail to drive the main body of the workshop to move.

[0015] Optionally, in the aforementioned installation workshop, the slide rail is made of I-beams or double-row angle steel.

[0016] Optionally, in the aforementioned installation workshop, the lattice column is welded from multiple angle steels.

[0017] Optionally, in the above-mentioned installation workshop, there are at least four cover plates, and at least two of the cover plates are inclined and intersect at the central axis of the main body of the workshop.

[0020] The installation workshop for offshore photovoltaic (PV) pre-assembly provided in this application, through a frame structure and a cover plate installed on top of the frame structure, forms an installation space for offshore PV pre-assembly. The installation space is equipped with hoisting equipment to facilitate the hoisting of components required for offshore PV pre-assembly. Furthermore, a movable device is installed at the bottom of the frame structure, which can move the main body of the workshop, thereby achieving partial or complete shading of the offshore PV pre-assembly site according to weather conditions. As can be seen from the above example, the installation workshop for offshore PV pre-assembly provided in this application can achieve partial or complete shading of the offshore PV pre-assembly site through the movable main body of the workshop, ensuring that pre-assembly work can continue even when encountering severe weather during onshore pre-assembly, thus improving the construction efficiency of offshore PV pre-assembly.

[0030] The core of this application is to provide an installation workshop for offshore photovoltaic pre-assembly, so as to improve the construction efficiency of offshore photovoltaic pre-assembly.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] During the construction of offshore solar power, the steel support structure, solar modules, and some electrical equipment are typically pre-assembled on land before being lifted to the sea and connected to the foundation. However, the pre-assembly process on land is frequently affected by severe weather, causing delays or even work stoppages, thus reducing the construction efficiency of offshore solar power pre-assembly.

[0033] Therefore, such as Figure 1 As shown in the illustration, this application discloses an installation workshop 100 for offshore photovoltaic pre-assembly, including a workshop main body 10, hoisting equipment 20, and a moving device 30. By moving the workshop main body 10, a partial or complete shading effect can be achieved on the offshore photovoltaic pre-assembly site, ensuring that the steel supports, photovoltaic modules, and some electrical equipment can still be pre-assembled even in adverse weather conditions during onshore pre-assembly, thereby improving the construction efficiency of offshore photovoltaic pre-assembly.

[0034] The following will combine Figures 1 to 3 The installation plant 100 for offshore photovoltaic pre-assembly disclosed in the embodiments of this application will be explained and described in detail.

[0035] like Figure 1As shown, the main body 10 of the plant may include a frame structure 11 and a cover plate 12 disposed on top of the frame structure 11, so that the frame structure 11 and the cover plate 12 enclose an installation space, within which the steel brackets, photovoltaic modules, and some electrical equipment of the offshore photovoltaic system can be pre-assembled. Simultaneously, a hoisting device 20 is provided within the installation space to facilitate the hoisting of parts required for the pre-assembly of the offshore photovoltaic system. Furthermore, a moving device 30 is provided at the bottom of the frame structure 11, which can move the main body 10 of the plant, thereby achieving partial or complete shading of the offshore photovoltaic pre-assembly site according to weather conditions. This ensures that the steel brackets, photovoltaic modules, and some electrical equipment can still be pre-assembled even in severe weather conditions encountered during the pre-assembly process on land, thus improving the construction efficiency of the offshore photovoltaic pre-assembly.

[0036] In some embodiments, such as Figure 3 As shown, the frame structure 11 can be composed of two rows of parallel lattice columns 111 and lattice beams 112 connected to the top of the lattice columns 111. The lattice beams 112 can include a first lattice beam 1121 and a second lattice beam 1122. Each row of lattice columns 111 can be connected by the first lattice beam 1121, and the ends of the two rows of lattice columns 111 can be connected by the second lattice beam 1122 to form the frame structure 11. Optionally, each row of lattice columns 111 can have five columns, and the lattice columns 111 and lattice beams 112 can be fixed by high-strength bolts or welding. Of course, each row of lattice columns 111 can also have two, three, four, or more columns, and the specific number of lattice columns 111 can be determined according to the actual space requirements of the installation workshop.

[0037] In some embodiments, such as Figure 3 As shown, the lattice column 111 may include members 1111 and tie bars 1112. Two, three, or more members 1111 may be used to form a double- or multi-member lattice column structure. Multiple tie bars 1112 may be used, and each tie bar 1112 may be welded between two adjacent members 1111 to ensure the overall stability of the lattice column 111. Optionally, the lattice column 111 may be constructed from angle steel, meaning both members 1111 and tie bars 1112 may be made of angle steel, and each tie bar 1112 may be distributed crosswise between two adjacent members 1111 and connected by welding to improve the load-bearing capacity and stability of the lattice column 111.

[0038] Of course, the lattice column 111 may also include members 1111 and gusset plates. There may be four members 1111, and the members 1111 may be made of angle steel, so that the four members 1111 enclose a square lattice column. At the same time, the gusset plates may be welded between two adjacent members 1111, and multiple gusset plates may be distributed along the height direction of the members 1111 to ensure the overall stability of the square lattice column.

[0039] In some embodiments, such as Figure 1 As shown, the lattice beam 112 can be composed of an upper chord 1123, a lower chord 1124, and web members 1125. The upper chord 1123, lower chord 1124, and web members 1125 can all be made of structural steel, such as angle steel. The web members 1125 are welded between the upper chord 1123 and the lower chord 1124, bearing the tensile or compressive forces caused by bending moments through the upper chord 1123 and lower chord 1124. Simultaneously, the web members 1125 can transfer shear forces to the upper chord 1123 and lower chord 1124, and also constrain the deformation of the lattice beam 112. The web members 1125 can be diagonal or vertical, and their arrangement can be determined according to the structural stress characteristics and design requirements. In this embodiment, the web members 1125 can be diagonal members, and there are multiple web members 1125. Each web member 1125 is arranged crosswise between the upper chord member 1123 and the lower chord member 1124 to ensure the overall load-bearing capacity and stability of the lattice beam 112.

[0040] To facilitate the installation of hoisting equipment 20, such as Figure 1 As shown, a support beam 13 is provided on the side of each row of lattice columns 111 facing the installation space, and the hoisting equipment 20 is movably mounted on the two support beams 13 so that the hoisting equipment 20 can be moved to hoist the parts required for the pre-assembly of offshore photovoltaics.

[0041] In some embodiments, such as Figure 1 As shown, the support beam 13 can adopt a corbel structure, and the support beam 13 can be prefabricated from steel. The support beam 13 is then welded to the lattice column 111 to achieve the installation and fixation of the support beam 13 and the lattice column 111.

[0042] like Figure 1 As shown, the hoisting equipment 20 may include a track beam 21 that moves along the support beam 13 and an electric hoist 22 that moves along the track beam 21. The track beam 21 is set perpendicular to the support beam 13 so that the electric hoist 22 can move horizontally and longitudinally, thereby facilitating the hoisting of parts required for the pre-assembly of offshore photovoltaic systems.

[0043] In some embodiments, such as Figure 1 As shown, a track 131 can be provided on the support beam 13 to facilitate the movement of the track beam 21. Simultaneously, a moving wheel is provided at the bottom of the track beam 21, allowing it to move along the track 131 under the drive of the driving component. It should be noted that the driving component can be a servo motor or a telescopic cylinder, or any other driving component capable of moving the track beam 21; this is not limited to any particular type.

[0044] To enable the electric hoist 22 to move along the track beam 21, in some embodiments, the electric hoist 22 can be fixed to the traveling trolley with fasteners such as bolts, while the wheels of the traveling trolley are in contact with the track beam 21. When the electric hoist 22 is working, the traveling trolley rolls along the track beam 21, thereby driving the electric hoist 22 to move on the track beam 21.

[0045] In some embodiments, one or more sets of wheels may be installed on the bottom of the traveling trolley, and the wheels are in contact with the surface of the track beam 21. When the motor drives the electric hoist 22 to rotate, it also drives the wheels of the traveling trolley to rotate through the transmission device. Relying on the friction between the wheels and the track beam 21, the electric hoist 22 moves along the track beam 21. To ensure the smoothness and accuracy of travel, the wheels can be made of high-strength, high-wear-resistant steel.

[0046] Furthermore, the movement between the electric hoist 22 and the track beam 21 can be controlled by a control system. The control system can receive operator commands and can also operate automatically according to a preset program. By controlling the motor's speed and direction, the position and speed of the electric hoist 22 on the track beam 21 can be accurately controlled.

[0047] like Figures 1 to 3 As shown, the moving device 30 may include a pulley 31 disposed at the bottom of the lattice column 111 and a slide rail 32 that cooperates with the pulley 31. The slide rail 32 may be fixed to the ground by high-strength bolts so that the pulley 31 can move along the slide rail 32, thereby driving the main body of the factory building 10 to move.

[0048] In some embodiments, such as Figures 1 to 3 As shown, each lattice column 111 can be equipped with multiple pulleys 31 at its bottom, and these pulleys 31 can be arranged in one or more rows. The slide rails 32 can be made of I-beams or double-row angle steel to form a sliding groove that engages with the pulleys 31, ensuring that the pulleys 31 move within the groove and preventing displacement when the main body of the factory building 10 moves. It should be noted that the movement of the main body of the factory building 10 can be achieved by driving one or more pulleys 31 of the two rows of lattice columns 111 to rotate using servo motors or other driving components. Alternatively, the movement of the main body of the factory building 10 can be achieved using other driving components, such as telescopic cylinders, etc., which are not limited here.

[0049] In some embodiments, such as Figure 1As shown, the roof of the main factory building 10 can be a pitched roof, meaning that at least four cover plates 12 can be used, and at least two cover plates 12 can be inclined and intersect at the central axis of the main factory building 10 to form a ridge line at the central axis of the main factory building 10. This facilitates water flow to drain along both sides of the ridge line and ensures a large clear space inside the main factory building 10, which is convenient for the pre-assembly of offshore photovoltaic systems. It should be noted that the roof of the main factory building 10 can use two cover plates 12 inclined and intersecting at the central axis of the main factory building 10 to form a two-sloped roof. Of course, all four sides of the roof of the main factory building 10 can also be sloped to form a four-sloped roof. At the same time, each side of the roof of the main factory building 10 can be covered with one or more cover plates 12, which is not limited here.

[0050] In some embodiments, the roof of the main building 10 may also be a flat roof, that is, one or more cover plates 12 may be used, and the cover plates 12 are laid flat on the top of the frame structure 11 and fixed together with the lattice beams 112 of the frame structure 11 by welding or bolting, so as to achieve the effect of covering a local area of ​​the offshore photovoltaic pre-assembly site.

[0051] In the above embodiments, in order to facilitate the construction and transportation of the roof, the material of the cover plate 12 can be a lightweight material, such as color steel plate, aluminum plate or polycarbonate sheet.

[0052] like Figure 2 As shown, an enclosure 14 can be installed on the outside of the frame structure 11 to achieve a closed installation space, thereby effectively blocking dangerous factors such as flying sparks, fragments, and chemicals, and reducing damage to the surrounding area.

[0053] In some embodiments, the enclosure 14 may be a protective curtain, which can be detachably connected to the lattice columns 111 of the frame structure 11 via bolts or other fasteners. This allows for switching between enclosed and semi-enclosed installation spaces, effectively blocking hazardous factors such as flying sparks, debris, and chemicals, reducing harm to the surrounding area. Simultaneously, the color and markings of the protective curtain can serve as a warning, reminding people to pay attention to safety. Furthermore, it isolates hazardous areas from non-hazardous areas, preventing unauthorized personnel from entering hazardous areas and reducing the likelihood of accidents.

[0054] The installation workshop 100 for offshore photovoltaic pre-assembly disclosed in this application, through a frame structure 11 and a cover plate 12 disposed on top of the frame structure 11, forms an installation space for offshore photovoltaic pre-assembly. Simultaneously, a hoisting device 20 is provided within the installation space to facilitate the hoisting of components required for offshore photovoltaic pre-assembly. Furthermore, a moving device 30 is provided at the bottom of the frame structure 11, which can move the main body 10 of the workshop, thereby achieving partial or complete shading of the offshore photovoltaic pre-assembly site according to weather conditions.

[0055] The installation workshop 100 for offshore photovoltaic pre-assembly disclosed in this application embodiment can achieve partial or complete shading of the offshore photovoltaic pre-assembly site through the movable workshop main body 10, so as to ensure that the steel bracket, photovoltaic modules and some electrical equipment can still carry out pre-assembly work when encountering severe weather during the onshore pre-assembly process, thereby improving the construction efficiency of offshore photovoltaic pre-assembly.
