[0039] like Figure 1-5 As shown, Figure 1 This is a schematic diagram of a structural embodiment of the transformer substation support platform for offshore photovoltaic systems disclosed herein. Figure 2 for Figure 1 The image shows a side view of the transformer substation support platform for offshore photovoltaic systems. Figure 3 for Figure 1 The image shows a rear view of the transformer substation support platform for offshore photovoltaic systems. Figure 4 for Figure 1 The image shows a partially enlarged view of the transformer substation support platform for offshore photovoltaic systems. Figure 5 for Figure 2 The image shows a partially enlarged view of the transformer substation support platform for offshore photovoltaic systems. Among other things, Figure 2 Some of the foundation piles were removed.

[0040] The support platform for the offshore photovoltaic substation includes: multiple foundation piles 1, a support platform 2, an oil tank bracket 3, and an oil tank 4. The foundation piles 1 are fixed on the sea surface; the support platform 2 is fixed on the foundation piles and is used to support the prefabricated substation; the oil tank bracket 3 is fixed on the side of the support platform facing the sea; the oil tank 4 is fixed on the oil tank bracket and is connected to the prefabricated substation via an oil pipe; the oil tank bracket includes a support part 31 and two limiting parts 32, the two limiting parts are connected to both ends of the support part, the support part is used to support the oil tank, and the end of the limiting part away from the support part is fixed to the support platform; the support part and the two limiting parts form a U-shaped groove, which is used to accommodate the oil tank.

[0041] This exemplary embodiment provides a support platform for a marine photovoltaic substation, which supports the entry and exit of the substation via a support platform 2, and simultaneously supports an oil tank 4 via an oil tank bracket 3. When oil-filled electrical equipment such as the substation malfunctions, the oil can flow into the oil tank through a drain pipe, thereby preventing oil leakage and the escalation of accidents such as fires. Furthermore, the oil tank bracket 3 includes a support portion 31 and two limiting portions 32, providing stable support and limiting of the oil tank.

[0042] In this exemplary embodiment, as Figure 1-5As shown, the offshore photovoltaic power plant's transformer substation support platform includes multiple oil tank supports 3, which are distributed at horizontal intervals. These multiple oil tank supports 3 provide more stable support for the oil tanks, for example, as... Figure 1-5 As shown, the transformer substation support platform for offshore photovoltaic systems may include two oil tank supports 3.

[0043] In this exemplary embodiment, as Figure 1-5 As shown, the oil tank support also includes multiple support vertical bars 33, which are fixed between the midpoint and end points of the support section. The support vertical bars extend vertically, and the length of the support vertical bars 33 furthest from the midpoint of the support section is greater than the length of the support vertical bars 33 closest to the midpoint. The support vertical bars 33 can form an arc-shaped support structure, which can match the arc-shaped circumference of the oil tank to provide more stable support for the oil tank.

[0044] In this exemplary embodiment, as Figure 1-5 As shown, the support platform includes multiple support ribs, among which are: main support rib 21 and secondary support rib 22; the cross-sectional area of ​​the secondary support rib 22 is smaller than that of the main support rib; the oil tank bracket 3 is fixed to the main support rib 21. The main support rib 21 has high strength, and in this exemplary embodiment, the oil tank bracket 3 is fixed to the main support rib 21, thereby improving the connection strength of the main support rib.

[0045] In this exemplary embodiment, as Figure 1-5 As shown, the oil tank support 3 is fixed to the end of the support platform in the first direction X; multiple oil tank supports are spaced apart along the second direction Y, the second direction intersects the first direction, and the first direction, the second direction, and the horizontal direction are parallel. The oil tank support 3 is fixed to the end of the support platform 2 in the first direction X, thereby reserving space at the bottom of the support platform 2 for setting up other structures. The multiple oil tank supports 3 are spaced apart along the second direction Y, and correspondingly, the length direction of the oil tank 4 can also extend along the second direction Y. This arrangement can further reserve space at the bottom of the support platform 2 for setting up other structures.

[0046] In this exemplary embodiment, as Figure 1-5 As shown, there is a preset distance between the oil tank 4 and the support platform 2. This arrangement can reduce the risk of collision between the oil tank 4 and the support platform 2.

[0047] In this exemplary embodiment, as Figure 1-5As shown, the distance S between the oil tank 4 and the support platform 2 is denoted as 'S', and the vertical dimension of the oil tank 4 is denoted as 'H'. The ratio of H / S is 2-5. For example, H / S can be equal to 2, 3, 4, or 5. If H / S is too small and S is too large, the height of the oil tank support 3 will be too large, making the oil tank support 3 unstable. If H / S is too large and S is too small, the oil tank 4 is prone to colliding with the support platform 2. This exemplary embodiment sets H / S to a suitable size, which can ensure the stability of the oil tank support 3 while reducing the risk of collision between the oil tank 4 and the support platform 2.

[0048] In this exemplary embodiment, as Figure 1-5 As shown, there is a preset distance between the oil tank 4 and the foundation pile 1. This setting can prevent the oil tank 4 and the foundation pile 1 from colliding. For example, the distance between the oil tank 4 and the nearest foundation pile 1 can be 0.1 meters to 2 meters. Optionally, the distance between the oil tank 4 and the nearest foundation pile 1 can be equal to 0.1 meters, 0.5 meters, 1 meter, 1.5 meters, 2 meters, etc.

[0049] In this exemplary embodiment, as Figure 1-5 As shown, the oil tank 4 includes a main body 41 and a cover 42. The main body is cylindrical; the cover 42 is located at both ends of the cylinder and has an outwardly convex arc surface structure. Both the main body 41 and the cover 42 have arc-shaped surfaces, which can reduce the risk of the oil tank 4 colliding and damaging other structures.

[0050] In this exemplary embodiment, as Figure 1-5 As shown, the tank support and the supporting platform surface can be welded. It should be understood that in other exemplary embodiments, the tank support and the supporting platform surface can be connected by fixing methods such as bolts.

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.
