[0039] like Figure 1-4 As shown, Figure 1 This is a schematic diagram of an exemplary embodiment of the offshore photovoltaic column-mounted transformer substation support platform disclosed herein. Figure 2 for Figure 1 The diagram shows another structural perspective of the offshore photovoltaic column-mounted transformer substation support platform. Figure 3 for Figure 1 The image shows a bottom view of the offshore photovoltaic column-mounted transformer substation support platform. Figure 4 for Figure 1 The image shows a top view of the offshore photovoltaic (PV) column-mounted transformer substation support platform. Among them, Figure 2 Two piles 1 were omitted.
[0040] The offshore photovoltaic (PV) gantry-type prefabricated substation support platform includes a prefabricated substation support assembly, which is used to house the prefabricated substation. The assembly includes: multiple pile foundations 1, a support platform 2, and vertical reinforcement 4. The multiple pile foundations 1 extend vertically and are spaced apart, and are fixed to the sea surface. The support platform 2 is fixed to the pile foundations 1 and is used to support the prefabricated substation. An auxiliary platform 3 is located between the support platform 2 and the sea surface. The vertical reinforcement 4 is fixed between the support platform 2 and the auxiliary platform 3. The auxiliary platform 3 is located within the space enclosed by the multiple pile foundations 1.
[0041] The prefabricated substation support assembly provided in this exemplary embodiment can not only support the prefabricated substation via the support platform 2, but also support devices such as submarine cables via the auxiliary platform 3. Furthermore, the auxiliary platform 3, located within the space enclosed by multiple pile foundations 1, can be physically protected by the pile foundations 1.
[0042] In this exemplary embodiment, as Figure 1-4 As shown, the auxiliary platform 3 includes: multiple first main ribs 31, multiple first secondary ribs 32, and multiple second secondary ribs 33. The multiple first main ribs 31 form a polygonal main frame; the multiple first secondary ribs 32 extend along a first direction X and are spaced apart along a second direction Y, and are fixed between opposite first main ribs 31 in the first direction X, where the first direction X and the second direction Y intersect; the multiple second secondary ribs 33 extend along the second direction Y and are spaced apart along the first direction X, and are fixed between opposite first main ribs 31 in the second direction Y; the cross-sectional area of the first main ribs 31 is larger than the cross-sectional area of the first secondary ribs 32, and the cross-sectional area of the first main ribs 31 is larger than the cross-sectional area of the second secondary ribs 33. In this exemplary embodiment, the auxiliary platform 3 is composed of a first main rib, a first secondary rib, and a second secondary rib. The first main rib 31 can improve the overall strength of the auxiliary platform 3, thereby facilitating the support of heavy components. The first main rib, the first secondary rib, and the second secondary rib can form a grid structure, which can facilitate the support of smaller components. At the same time, the first secondary rib and the second secondary rib can reduce the weight of the auxiliary platform 3, thereby reducing the load on the support platform 2.
[0043] In this exemplary embodiment, as Figure 1-4 As shown, the first secondary rib 32 and the second secondary rib 33 intersecting with it are fixedly connected. The first secondary rib 32 and the second secondary rib 33 intersecting with it can form a grid structure, which can be used to support devices such as submarine cables.
[0044] In this exemplary embodiment, as Figure 1-4 As shown, the vertical reinforcement 4 is fixed between the first main reinforcement 31 and the supporting platform 2. The first main reinforcement 31 has high strength, and the auxiliary platform 3 is fixedly connected to the first main reinforcement 31 and the vertical reinforcement 4, thereby improving the stability of the auxiliary platform 3.
[0045] In this exemplary embodiment, as Figure 1-4 As shown, the vertical reinforcement 4 is fixed at the intersection of two adjacent first main reinforcement bars 31, and the vertical reinforcement 4 can be fixedly connected to the two adjacent first main reinforcement bars 31. The intersection of the two adjacent first main reinforcement bars 31 is the location where the main frame formed by the first main reinforcement bars 31 is weaker. This exemplary embodiment improves the overall strength of the auxiliary platform 3 by connecting the vertical reinforcement 4 to the intersection of the two adjacent first main reinforcement bars 31.
[0046] In this exemplary embodiment, as Figure 1-4 As shown, the transformer substation support assembly includes a ladder 5, which is fixed to the pile foundation 1. One end of the ladder 5 extends to the support platform 2, and the other end extends to the sea surface. Workers can use the ladder 5 to enter or leave the support platform 2 to install and maintain the components on the support platform 2.
[0047] In this exemplary embodiment, as Figure 1-4 As shown, the auxiliary platform 3 is octagonal in shape. Accordingly, the auxiliary platform 3 can be fixedly connected to the supporting platform 2 via eight vertical ribs 4. It should be understood that in other exemplary embodiments, the auxiliary platform 3 can also be other closed shapes, such as circles, other polygons, irregular shapes, etc.
[0048] In this exemplary embodiment, as Figure 1-4 As shown, the area occupied by the support platform 2 is larger than the area occupied by the auxiliary platform 3. The support platform 2 can be located at least partially outside the area enclosed by the pile foundation 1, so that the support platform 2 has a larger space.
[0049] In this exemplary embodiment, as Figure 1-4 As shown, the support platform 2 includes: multiple second main reinforcement bars 21, multiple third main reinforcement bars 22, and multiple third secondary reinforcement bars 23. The multiple second main reinforcement bars 21 extend along a first direction X and are spaced apart along a second direction Y, where the first direction X and the second direction Y intersect. The multiple third main reinforcement bars 22 extend along the second direction Y and are spaced apart along the first direction X, with the second main reinforcement bars 21 and at least a portion of the intersecting third main reinforcement bars 22 fixedly connected. The multiple third secondary reinforcement bars 23 extend along the second direction Y and are spaced apart along the first direction X, with at least a portion of the intersecting second main reinforcement bars 21 fixedly connected. The cross-sectional area of the second main reinforcement bars 21 is larger than that of the third secondary reinforcement bars 23. Vertical reinforcement bars 4 are fixed to the second main reinforcement bars 21 or the third main reinforcement bars 22. The larger cross-sectional areas of the second main reinforcement bars 21 and the third main reinforcement bars 22 can improve the overall strength of the support platform 2, while the fixing of the vertical reinforcement bars 4 to the second main reinforcement bars 21 or the third main reinforcement bars 22 can improve the stability of the auxiliary platform 3. The third secondary rib 23 can form a smaller grid structure with the second main rib 21 and the third main rib 22 to support small-volume components.
[0050] In this exemplary embodiment, as Figure 1-4 As shown, the first main reinforcement 31 and the vertical reinforcement 4 are I-beam structures. The second main reinforcement 21 and the third main reinforcement 22 can also be I-beam structures. It should be understood that in other exemplary embodiments, the first main reinforcement 31, the vertical reinforcement 4, the second main reinforcement 21, and the third main reinforcement 22 can also be other structures.
[0051] In this exemplary embodiment, as Figure 1-4 As shown, the transformer substation support components may include steel structures, aluminum structures, etc.
[0052] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
